一种餐厨垃圾的预处理装置

Kitchen waste pretreatment device

Abstract

The utility model provides a kitchen waste pretreatment device, which comprises a discharge device, wherein the discharge device is communicated with a crusher; the outlet of the crusher is connected with the inlet of a screw extruder; a screen mesh is arranged in the screw extruder; a slag discharge opening is formed in one side of the screw extruder; the bottom of the screw extruder is communicated with a triphase separator; the triphase separator is connected with a heating tank through a pump; the heating tank is connected with a grit-water separator; the kitchen waste enters the crusher from the discharge device for crushing; the crushed materials are fed into the screw extruder for extrusion and filtering; slurry enters the triphase separator for separation and then fed in the heating tank for heating to 50 DEG C through the pump; the solid content ratio of the materials in the heating tank is adjusted to be 5%; the materials are fed in the grit-water separator through a discharge pump at the feeding speed; the water flow with pressure enters from the water inlet of the grit-water separator in the tangential direction, the water with low density rises and is discharged from a water outlet, and grains of sand with high density are discharged from a pollutant discharge opening in the bottom of the equipment; the kitchen waste treatment pretreatment device has the characteristics that the structure is simple, the process is simple, the service lives of other equipment are prolonged, and the failure rate is reduced.
