Environmental protection planning of automatic Foundry: decoration layout of die casting workshop to reduce energy consumption

Environmental protection planning of automatic Foundry: decoration layout of die casting workshop to reduce energy consumption



A metal casting process is characterized in that a mold cavity is used to apply high pressure to molten metal. The mold is usually made of alloy with higher strength. This process is somewhat similar to injection molding. Most die castings are iron free, such as zinc, copper, aluminum, magnesium, lead, tin and lead tin alloys and their alloys. Depending on the type of die casting, it is necessary to use a cold chamber die casting machine or a hot chamber die casting machine. Powerful enterprises will also introduce advanced technology and management mode to realize the automation and intelligence of die-casting production, which plays a very important role in optimizing the die-casting process, improving the economic and technical indicators of the die-casting workshop, and improving the ability to produce high-performance and high-precision parts. In recent years, the zinc die-casting industry in China has developed rapidly. Many enterprises have invested in the research and development of new processes, new technologies and new equipment, which have created a good foundation for the efficient production of the zinc die-casting industry. The following is about the construction of the die casting plant.



The planning of die casting workshop is an important link in the construction of die casting factory. First of all, we should make clear the planning purpose of the die casting workshop: according to the guidelines and policies of the national industrial construction, absorb the latest scientific research achievements and practical experience of the die casting industry at home and abroad, select the appropriate plant site, determine the appropriate production scale, design various technological processes, select reasonable production equipment, equip necessary labor personnel, and scientifically formulate various economic and technical indicators of the workshop.



For the site selection of die casting plant, the factors such as geography, geology, climate conditions, supply of raw materials, fuel and power, transportation and other supporting industries shall be comprehensively investigated. Ensure convenient transportation, abundant power resources such as raw materials, water, electricity and gas, and perfect supporting industries, so as to save manpower, material resources, transportation, energy and environmental treatment costs to the greatest extent. The scale of the die casting workshop shall be determined according to the enterprise's own economic conditions, current production tasks and future development prospects. It must not only meet the current production needs of the enterprise, but also leave enough space for future development. He has rich experience in workshop transformation, so when many old plants need to be upgraded into modern workshops with automatic / semi-automatic R & D and production integration, he habitually finds Muya and hopes to help the enterprise complete the upgrading and transformation tasks with the help of Muya's experience in EPC integration services in this field.



The "production process flow" of the die casting workshop is the main basis for planning and design. The height, span and column spacing of the workshop shall be determined according to the size of the die casting machine and the level of automation in the workshop. According to the type of factory and the nature of products, the production equipment configuration of the die-casting workshop is also particular. Let's first take a look at the equipment volume of the die-casting workshop (large amount of equipment and heavy equipment). > > Business negotiation, click here, online consultation



Main equipment of die casting workshop:



Smelting equipment, die casting equipment, cleaning and polishing equipment, processing equipment, surface treatment equipment, etc.



Auxiliary equipment of die casting workshop:



Cooling water supply equipment, such as cooling water tower and chiller; Lifting and transportation equipment, such as crane, forklift, conveyor belt, compressed air supply equipment, ventilation and exhaust, smoke control equipment, testing and testing equipment, etc. According to the level of automation, some equipment is also equipped with various types of peripheral equipment, such as the peripheral equipment of the die casting machine, such as automatic soup dispenser, automatic soup feeder, automatic spray machine, and automatic parts taking machine.



During the graphic design, the designer shall fully consider the installation of workshop equipment, logistics channels, lighting, ventilation and exhaust, waste gas treatment and other factors, especially the ventilation and exhaust system. As the designer shared with us, in the process of die casting production, many links will produce smoke, harmful gas, oil droplets, oil pollution, noise and heat radiation. When the amount of these pollutants exceeds the national or local standards, It will affect or pollute the environment. In order to ensure the good production environment of the workshop and the health of workers, from the perspective of clean engineering design and construction, we will focus on the design of ventilation and exhaust system of the supporting system of the production workshop. In addition, the plane planning of the die casting workshop should also pay attention to the following contents:



1. The die casting workshop belongs to the hot processing workshop, which generates more smoke. From the perspective of environmental protection, the die casting workshop should be arranged in the downwind area of the prevailing wind direction in summer and far away from the factory entrance. However, it shall not be close to the forging press and sand mold casting workshop.



2. Considering the convenient transportation of castings, it shall be as close to the machining workshop as possible.



3. According to the production scale, technical level and development possibility of the plant, there should be room for development.



4. To create a good working environment, natural ventilation and natural lighting shall be fully utilized to avoid the western sun. The longitudinal skylight axis of the plant shall form an angle of 60-90 ° with the prevailing wind direction of summer wind, so as to discharge smoke and harmful gases.



5. According to the fire protection requirements, there should be a certain distance between the die casting workshop and the adjacent buildings, and there should be a road for fire engines around the workshop.



6. The magnesium alloy die casting workshop shall be an independent single storey building, and the floor of the workshop shall be higher than other floors.



7. In the construction of die casting workshop, attention should be paid to the comprehensive treatment of waste water, slag, smoke and exhaust gas.



Die casting production is a high energy consumption and polluting industry. Enterprises need to strengthen the environmental management of the workshop when building the workshop. "How to reduce energy consumption?" This ultimate goal runs through the whole layout design and process design. This is also the design and decoration concept that professional clean engineering integration service providers such as Muya have always implemented in the design and decoration.
