Green design analysis of light industrial machinery

1 background

green design, in short, refers to the design aimed at making efficient use of resources and energy to obtain green products. Green products refer to products that do not cause harm to the environment (including animals and plants) and human health on the premise of having specific functions

Green design, which can be calibrated according to the instruction manual, is an advanced design idea rising internationally in the early 1990s. The direct background is that the international community pays more and more attention to sustainable development and human health

in the past 200 years, the world has achieved rapid development, and its development model is basically achieved at the cost of a large consumption of resources and energy (especially disposable resources and energy). However, the disposable resources and energy on the earth are limited after all. With the increasing population of the world and people's higher and higher requirements for material life, whether this development mode of high investment and high output can continue and how long it can last has become a key research topic of the international community, and there have been a series of theories related to it, such as the quadruple factor theory and the development limit theory. The analysis and demonstration shows that changing the traditional extensive development mode of high investment and high output and adopting the intensive development mode characterized by the efficient utilization of resources and energy is the fundamental way to achieve sustainable development, and green design takes the efficient utilization of resources and energy as its fundamental starting point

at the same time, the massive exploitation and inefficient utilization of resources and energy have also caused a large number of wastes (including many toxic and harmful substances) to enter the environment, forming a series of environmental problems represented by the ten major environmental problems, deteriorating the environmental quality on which human beings and other animals and plants rely for survival and obtain a high-quality life, and posing a threat to human health and even life safety. In addition, due to the traditional emphasis on product functions, some products introduce substances harmful to human body in the production process, such as pesticides, volatile organic solvents and even radioactive substances, so that people are not only enjoying their functions, but also paying the cost of health. This series of problems are causing the international community to reflect, and actively explore in product objectives, product design and manufacturing mode, human consumption lifestyle, etc., with a view to enjoying a healthy, comfortable and convenient green life in a green environment in the near future. Green design is the starting point and the most important link to realize the above ideal

To sum up, green design is an inevitable requirement for human beings to achieve sustainable development, have a high-quality living environment and enjoy a healthy life, and it is also the general trend of future technological and economic development

2 internal letter of green design

2.1 definition of green design

green design is such a plan that Huaibei city also promotes demonstration utilization in multiple ways, that is, in the whole life cycle of products (design, manufacturing, transportation, sales, use or consumption, waste treatment), it focuses on considering the environmental attributes of products (utilization of natural resources, impact on the environment and people, disassembly, recyclability, reusability, etc.), And take it as the design goal. While meeting the requirements of environmental goals, the basic functions, service life, economy and quality of the product should be considered and guaranteed in parallel

2.2 characteristics of green design

(1) design objectives in addition to considering functions, performance, quality, cost and other aspects, we must also consider the friendliness of products with the environment and people in the whole life cycle

(2) in addition to conventional design methods, design technology must also have new design ideas and methods such as human removable design, recyclable design, modular design, etc

(3) design evaluation comprehensively considers that the total load on the environment in the whole life cycle, such as raw material extraction, material processing, component manufacturing, product assembly, product packaging, product transportation, product use, recycling, reuse and treatment after product abandonment, is the minimum

(4) the design process is parallel closed-loop design. In green design, the abandoned products are not discharged into the environment as garbage, but are considered to be re applied to the manufacturing process of new products through reuse, repair, reprocessing, recycling and other means, so that the ideal green products can be close to achieving zero emission to the environment

(5) the design purpose takes into account the needs and environment

2.3 key technologies of green design

(1) green material design includes the design technology of photodegradable or biodegradable materials in the environment and the development and application of natural materials

(2) material selection and management minimize the types of materials, minimize the use of toxic and harmful materials and precious and scarce materials, and try to do a good job in material classification management and recycling of waste and leftover materials

(3) modular design shall be adopted for the removable and easy recycling design of products, the connection method easy to disassemble shall be adopted, and the coating treatment of material surface shall be minimized

(4) green process design realizes low or even zero emissions through process simplification, comprehensive utilization and recycling of raw materials and auxiliary materials and by-products in the production and manufacturing process

(5) renewable energy should be used as much as possible in the design of green energy consumption scheme to improve the energy utilization rate and strengthen the comprehensive utilization of energy and waste heat recovery

(6) environmental and social cost assessment includes environmental pollution control cost, environmental restoration cost, waste social treatment cost, medical cost causing damage to human health, etc

(7) waste recycling, treatment and recycling, including waste reduction, harmless, waste recycling and reuse technology, waste deep processing and recycling technology, etc

(8) green design database, knowledge base and green design integration tools include material performance database, material environmental load database, energy production and utilization environmental load database, domestic and foreign laws, regulations and standards, quantitative evaluation index system, computer-aided green design tools, etc

2.4 typical green design Wearable flexible strain sensors have become the key research direction for the development of intelligent materials in the future. Methods

(1) life cycle design is a design method that comprehensively considers the impact of various links in the life cycle, such as research, development, design, manufacturing, sales, use, recycling, treatment, on the environment and people

(2) concurrent engineering design uses concurrent engineering technology, comprehensively considers various factors in product green design, and carries out information exchange and feedback between links at any time in the design process, so as to realize the global optimization of multi factor, multi-objective and closed-loop design process

(3) modular design can realize the integration of function and structure, and then realize the rapid development of green products and the requirements of easy disassembly and recycling

3 analysis of special work required for green design of light industrial machinery

light industrial machinery covers papermaking, plastics, brewing beverages, dairy products, leather, clothing, ceramics, sugar making, washing, daily chemical industry, daily glass, woodworking furniture, blades, packaging and decoration clocks, five gold, batteries, lighting appliances, salt making machinery, etc. (quoted from "China light industrial machinery communication")

it can be seen that light industrial machinery covers many industries, and the types of materials handled by various machines vary greatly. Therefore, in order to realize the green design of light industrial machinery, in addition to the basic key technologies required by the above green design, the following basic work is required:

(1) physical property data research and physical property database construction of pulp, plastics, dairy products, glass and other materials

4 application prospect of green design in light industrial machinery design

4.1 green design of light industrial machinery can improve the competitiveness of light industrial machinery products and enterprises

one of the essential characteristics of green design is an advanced design method to improve the utilization of resources and energy through technology and management

without affecting the traditional indicators such as function, life and quality of products. In the sense of economics, green technology is a technology that reduces the cost of products and adds value to technology or resources and energy. That is, on the premise of the same amount of resources and energy, green design technology is an advanced design technology that strives to obtain more and better products than traditional design methods and makes the production process from extensive to intensive, which is full of vitality. With the integration of China into the world market, the market competition of light industrial machinery products will become increasingly fierce, and green design technology is a powerful weapon to improve the competitiveness of products and enterprises

4.2 the green design of light industrial machinery can effectively reduce the environmental risks in the development of enterprises

with the continuous improvement of social requirements for environmental protection, light industrial enterprises with heavy waste treatment tasks such as papermaking, sugar making, leather, brewing, washing, etc. if they do not adopt high-performance machinery with green design, they will be in danger of being shut down, stopped, merged and transferred due to environmental problems at any time, which will cause serious hidden dangers in the development of enterprises. On the contrary, if enterprises adopt light industrial machinery based on green design to realize cleaner production, it can create a space for enterprises to develop continuously, stably and efficiently

in addition, light industrial machinery with green design can also provide a good working environment for on-site staff with a large amount of safety reserves and improve work efficiency due to low noise and friendly man-machine interface. In conclusion, a series of advantages of light industrial machinery with green design technology show that the green design of light industrial machinery has a good application prospect. (end)
