Abstract
The invention discloses a pretreatment device for kitchen waste. The pretreatment device comprises a material discharging device, wherein the material discharging device is communicated with a crushing machine; an outlet of the crushing machine is connected with an inlet of a spiral extruder; a screen is arranged in the spiral extruder; a slag discharging opening is formed in one side of the spiral extruder; the bottom of the spiral extruder is communicated with a three-phase separator; the three-phase separator is connected with a heating tank through a pump; the heating tank is connected with a sand-water separator. A pretreatment method for the kitchen waste comprises the steps of (1) pouring the kitchen waste into the material discharging device, and crushing the kitchen waste through the crushing machine; (2) conveying the crushed materials into the spiral extruder for extrusion filtering, and separating slurry entering the three-phase separator; (3) pumping the slurry into the heating tank and heating to 50 DEG C, adjusting the solid content of the materials in the heating tank to be 5 percent, and conveying the materials into the sand-water separator through a material outlet pump at the speed same as the material feeding speed; and (4) enabling pressurized water flow to enter the sand-water separator from a water inlet of the sand-water separator in a tangent manner, wherein water with low density rises up and is discharged from a water outlet, and sand with high density is discharged from a pollutant discharging outlet in the bottom of device.
