Background

The kitchen waste is also called swill and hogwash, is a domestic waste formed in the process of domestic consumption, is extremely easy to rot and deteriorate, emits foul smell, and transmits bacteria and viruses, the main components comprise rice and flour food residues, vegetables, animal and vegetable oil, meat and bones and the like, the water content of the kitchen waste is up to 80-95%, and if the kitchen waste is not treated in time, the kitchen waste pollutes the environment, harms the health of human bodies and transmits diseases. In the process of waste treatment, the step of dewatering is very important. Because wet rubbish water content is very high, if do not carry out effectual dehydration, can aggravate the burden when dry, the extravagant energy, current equipment adopts screw extrusion dewatering equipment more often.

As shown in the 'kitchen garbage dewatering device' disclosed in the Chinese utility model with the patent number of CN201822214289.3 (the publication number of CN209682996U), the squeezing roller is arranged in the shell, the squeezing roller close to one end of the shell with the feed inlet is a conical section, the squeezing roller close to the other end of the shell is a cylindrical section integrally connected with the conical section, the conical section and the cylindrical section are provided with helical blades, the surface of the lower end of the shell is provided with a plurality of openings, a water collecting tank is arranged below the plurality of openings, and the lowest point of the water collecting tank is provided with a water outlet. The conical section not only conveys materials, but also can extrude and dewater the materials.

But have hard material in the rubbish, for example bone etc. difficult quilt is smashed, if the volume of hard material is great, blocks up the discharge gate easily in discharge gate department to because the external diameter of toper section is crescent from feed inlet to discharge gate, hard material still blocks between shells inner wall and squeeze roll easily, leads to the rotation that the squeeze roll can not be normal.
