—Focus on the research, development and production of full-automatic horizontal stripping molding machine!!
In the past three or four years in China, in order to improve the prevention and control of air pollution in Beijing, Tianjin, Hebei and surrounding areas, the relevant environmental protection departments in some regions have upgraded and transformed the regional foundry enterprises according to the environmental protection policies, and directly listed the foundry industry in some regions (such as residential land, high-tech enterprise land, etc.) as the industries to be withdrawn from the list; while for the regions with more concentrated Foundry Enterprises According to the environmental protection policy and the requirements put forward by China Foundry Association, some foundry enterprises that do not respond to the environmental protection requirements within the specified period and do not report the project will be considered as quitting. After the rectification and acceptance, the enterprises can continue to produce. In winter, they need to implement peak shifting production according to the local weather warning.
At present, the main areas with centralized rectification and specific indicators in China are Botou, Xianxian, Shijiazhuang, Laizhou and Weifang in Shandong Province; most areas (such as Xuchang, Changge and Linzhou in Henan Province) have relatively unclear environmental protection policies, and the specific requirements for rectification of foundry enterprises (sand casting) are as follows:
15mg/m2
First of all, the foundry enterprise shall report the current basic situation - plant area, production scale, production process and current production equipment, and make a detailed rectification plan for its own enterprise according to the environmental protection index. For example, the smelting equipment shall adopt the steel shell electric furnace, the furnace top shall be equipped with dust absorption hood, which can achieve 90% leakage free collection, and the exterior shall be equipped with bag filter to ensure the powder There is no leakage of dust, and the emission concentration of dust particles is less than 15mg / m2;
UV15mg/m25mg/m2
The backward manual or semi-automatic sanding molding will be eliminated in the sanding molding. Relevant molding equipment and molding line, pouring line, cooling line, etc. shall be equipped to ensure that the sand does not fall on the ground during the production process. The pouring line and cooling line at the fixed pouring end shall adopt side suction dust removal or fully enclosed dust removal cover. The gas shall be subject to dust removal and bag treatment before entering the UV light oxygen for secondary treatment to ensure the powder The emission concentration of dust particles is less than 15mg / m2, and the emission concentration of post particles is less than 5mg / m2; ensure that the closed link is tight without dust overflow; the sand falling link at the end of the production line also needs to adopt closed dedusting;
15mg/m2
In the sand treatment process, the sand treatment production line shall be installed according to the plant design, and the automatic sand mixing and automatic conveying shall be carried out to provide molding sand for the molding equipment. In the screening process and sand mixing process, bag type dust removal equipment shall also be installed to remove dust from the used sand, so as to ensure that the sand does not fall on the ground and no dust particles overflow, and the emission concentration of dust particles is less than 15mg / m2;
80
Bag type dust removal is also used in cleaning and throwing process to ensure no dust spillage. Sound insulation and silencer and damping pad are installed in the dust remover to reduce noise and ensure that the noise level within the plant boundary is not more than 80 dB;
GB50016-2014
Requirements for supporting facilities in the plant area, such as:
Fire fighting facilities: fire extinguishers shall be placed at the designated position of the workshop, and the word "emergency exit" shall be marked on the floor of the workshop passage. Smoke alarms, escape signs, alarm facilities, etc. shall be set in the workshop according to the code for fire protection design of buildings (gb50016-2014);
Safety facilities: safety signs shall be set up in the workshop, safety appliances and other safety supplies shall be placed and management shall be strengthened;
Sanitary facilities: set up fixed storage points for industrial waste and domestic waste, regularly carry out outbound treatment, and assign special personnel to carry out environmental health maintenance in each area of the plant, so as to make the plant clean and tidy;
5S
The requirements for enterprise management are as follows:
The internal and external environment of the plant area shall be hardened, both sides of the road shall be afforested, and the public activity area and parking area shall be set up and divided; the 5S management concept shall be implemented: for example, the reasonable transfer, storage, placement and warehousing of finished products shall be strictly in accordance with the specified process for standardized management, regular inspection, maintenance and management of public and auxiliary facilities by specially assigned personnel, which shall be clear and standardized;
