Description

A kind of leather material pulverizer

technical field

The utility model relates to a pulverizing machine, in particular to a leather material pulverizer. the

Background technique

In recent years, with the increasingly severe global ecological problems such as resources and environment, my country's leather industry is facing the severe challenge of the "sustainable development" strategy. my country is a big country in the leather industry. The traditional leather industry has caused a large loss of animal resources. The solid waste generated by cutting and tailoring after tanning accounts for about 30%. my country produces more than 1.4 million tons of leather waste every year. If If these solid wastes cannot be treated reasonably, on the one hand, it will seriously pollute the environment, and on the other hand, it will also cause a large loss of collagen fibers. Therefore, the reuse of leather waste has become one of the important topics that domestic and foreign tannery and environmental protection workers pay attention to and devote themselves to research. Extracting long collagen fibers from it is one of the effective ways. Collagen long fiber is a natural fiber, which has the characteristics of strong tensile force, strong hygroscopicity, softness, no peculiar smell, antistatic and flame retardant. the

Products such as pigskin, cowhide, horsehide, sheepskin and other animal skins are processed as raw materials for various genuine leather garments, bags, footwear, wallets, belts, etc., which have always been favored by human beings. The following two methods are usually used to dispose of the unreusable leftovers cut during the processing: one is to bury them in a centralized manner; the other is to incinerate them. Landfill will pollute the soil, because this kind of leftover material is cut or left from the finished leather. The rotting period of the treated waste leather is extremely long, and even if it rots, it will cause harm to the soil quality. In addition, it will also damage the water system environment, because when the water seeps into the soil filled with waste leather, it will naturally bring water pollution. Hazardous pollution; incineration will pollute the air, and the diffuse smoke and odor produced during incineration will immediately damage human health. In addition, since incineration is a diffuse combustion, it takes a long time to burn out, which often causes fires. Therefore, for the current manufacturers of genuine leather processed leather products, not only can not make the best use of everything, but they are often troubled by the waste disposal of discarded corners. the

With the increasingly stringent environmental protection requirements, the binding force on leather product manufacturers in the disposal of waste scraps is becoming more and more restricted, and the environmental protection fees charged by the environmental protection department are increasing day by day. However, this is only treating the symptoms and not the root cause, because so far, no matter whether it is domestic or foreign, the traditional incineration and landfill treatment are still basically continued. Although people all know that a large amount of ingredients in animal skins such as pigskin and cowhide are fibers, it is a very regrettable thing to landfill and burn them without utilizing them. Because once the fiber can be extracted, the extracted fiber can be applied to textiles after treatment, so as to solve the problem of environmental protection and make the best use of everything. Therefore, if a cheap and simple-structured special device for leather crushing can crush such scraps, it would be a good move. The existing leather is broken and the shearing structure adopts the upper and lower blades to fully contact and shear the leather. This kind of shearing equipment has the defects of high power consumption, low shearing efficiency, easy to wear and loud noise. the
