Sorting equipment for kitchen waste

Abstract

The invention discloses sorting equipment for kitchen waste, and relates to the field of environmental protection. The sorting equipment for the kitchen waste comprises a feeding spiral sorting machine, a roller and a first driving mechanism, wherein the feeding spiral sorting machine comprises a material conveying barrel, a spiral conveying blade, a second driving mechanism and an extruding mechanism, the material conveying barrel is provided with a material inlet, a first material outlet, first-stage sieve holes and filter holes, the spiral conveying blade is arranged in the material conveying barrel, the second driving mechanism is in transmission connection with the spiral conveying blade, the extruding mechanism is arranged at the material discharging end of the material conveying barrel, so that material residues obtained after first-stage sieving undergo the extruding treatment to be discharged through the first material outlet, the second end of the roller is lower than the first end of the roller and is provided with a second material outlet, the roller sleeves the material conveying barrel, moreover, a second-stage sieve cavity is formed between the roller and the outer wall of the material conveying barrel, second-stage sieve holes are formed in the roller, and the first driving mechanism is in transmission connection with the roller. According to the sorting equipment, the purpose of synchronously performing two stages of screening can be realized, and meanwhile, the service life of the sorting equipment for the kitchen waste is prolonged.

Description

technical field [0001] This application relates to the field of environmental protection, in particular, to a sorting device for kitchen waste. Background technique [0002] There are a lot of foreign substances in the kitchen waste, such as glass, ceramics, bones, tableware, sand and gravel, etc. If such non-degradable foreign substances are not sorted during the treatment of kitchen waste, it will cause serious damage to the processing equipment. Wear or damage reduces the service life of the equipment, and at the same time it is easy to block pipes and switches in subsequent processing structures. [0003] Although the sorting equipment with crushing can break bags or crush organic matter, it will also produce destructive foreign matter such as ceramics, glass fragments, bones, and shells. These destructive foreign objects will aggravate the wear and tear of subsequent processing equipment, pipeline blockage and other problems, and even stop production for maintenance. ...

AI Technical Summary

Problems solved by technology

These destructive foreign bodies will aggravate the wear and tear of subsequent processing equipment, pipeline blockage and other problems, and even stop production for maintenance

Moreover, high-speed crushing and sorting equipment consumes a lot of power. The high-speed rotating crushing shaft is easily damaged by hard materials such as metal, and the low-speed cutting tool shaft is easily entangled by plastic bags and fabric kitchen waste.

Therefore, the sorting equipment with crushing has a high failure rate, serious wear and tear, and large power consumption
