Geometric-pitch screw extrusion pulverization lifting box

Abstract

The invention discloses a geometric-pitch screw extrusion pulverization lifting box which comprises a lifting box body, a screw conveying extrusion device, a grinding device and a drive device, wherein the lifting box body is inclined upwards, and the height of a feed inlet of the lifting box body is smaller than that of a feed outlet of the lifting box body; the screw conveying extrusion device is arranged inside the lifting box body, and is used for extruding and dewatering materials simultaneously in the process of conveying the materials; the grinding device is arranged behind the screw conveying extrusion device, and is used for extruding and grinding the materials which are extruded and dewatered by the screw conveying extrusion device; the drive device is arranged at the outer side of the lifting box body, and is used for providing power output for the screw conveying extrusion device and the grinding device; and an opening is formed at a bottom plate at the feed inlet of the lifting box body and a filter screen for filtering out residual liquid in the conveying process is arranged on the bottom plate. The geometric-pitch screw extrusion pulverization lifting box disclosed by the invention can effectively lower the solid humidity of kitchen wastes and meets requirements on the solid kitchen waste humidity in the fermentation process.

Description

technical field [0001] The invention relates to an equal-pitch helical extrusion crushing lifting box. Background technique [0002] Food waste refers to food leftovers discarded during food processing, food leftovers after eating and drinking, and untreated sewage generated in the process of washing food and washing tableware. Its components mainly include peel and broken bones, meal crumbs, insoluble protein, fibrous and starchy insoluble organic matter, and its composition is extremely complex according to different meals. Since food waste is rich in nutrients, if it is discharged directly into the natural world without treatment, it will rot and deteriorate in a short period of time under the action of suitable temperature and bacteria, which will not only pollute the surrounding environment, breed mosquitoes and flies, but also invade a large number of wastes. land, but also cause a lot of waste of resources. Based on this, the research and development of food waste t...

Problems solved by technology

However, due to the influence of the viscosity and concentration of food waste on the crushing effect, it is often difficult for the general rotor hammer crushing equipment to achieve the expected effect. After crushing, the solid humidity still reaches 70%, and the noise is relatively large and the minimum reaches 5.0P. In order to meet the For the condition requirements in the fermentation process of solid food waste, it is necessary to further squeeze and pulverize the crushed solid food waste
