The Design of a Light Leather Factory Manufactures 2400 pieces
of Cattle Hide (Upper Leather) daily
ABSTRACT
This design is about a tannery, which can produce 2400 pieces of cattle hide leather (Upper leather) every day. The site selected in Guigang Guangxi Dragon Pearl green leather industrial city. This design make a simple analysis of the current situation about the leather industry at home and abroad, and a detailed argument to the finished product standards and environmental protection requirements on the production process, and to give priority to domestic equipment, the choice of a steel frame structure plant to build factories. The factory The factory The factory covers an area of 4545 acres,employs 230 people, 203 ordinary workers, 27 managers and technical staff. Each of leather that processing compeleted consumption chemical materials worth 138.5 yuan., and water consumption 0.466 t, power consumption 3.65 degrees, gas consumption of 17.8 kg. Total equipment investment costs 11.8726 million yuan , the profit is 114.065 million yuan each year.The plant is equipped with a complete sewage treatment facilities, ensure that the sewage to reach the national standard, and to adapt to the new era enterprise development requirements.
