Large-substance sorting system for food waste

Abstract

The invention discloses a large-substance sorting system for food waste. The large-substance sorting system comprises a sorting mechanism, wherein the sorting mechanism comprises a screen, a sorting assembly, a rotary transmission assembly which is in transmission connection with the sorting assembly, and a driving assembly which is in transmission connection with the rotary transmission assembly;the sorting assembly comprises a swing shaft which is in transmission connection with the rotary transmission assembly, and stirring paddles which are arranged on the swing shaft; the screen is an arc-shaped grating plate, is obliquely arranged, and comprises a first supporting piece, a second supporting piece, a plurality of grating holes, a plurality of arc-shaped spacing plates and a pluralityof straight rods, the two ends of the arc-shaped spacing plates are connected with the first supporting piece and the second supporting piece, each straight rod penetrates through the plurality of arc-shaped spacing plates, and the grating holes are composed of the arc-shaped spacing plates and the straight rods; and swinging arcs of the stirring paddles are parallel to extension lines of the arc-shaped spacing plates, and round tubes are rotationally arranged on the parts, forming the grating holes, of the straight rods in a sleeve mode. The large-substance sorting system has the advantagesthat the high screening purity of large substances is achieved, the screening efficiency is high, and the screen is not easy to block.

Description

technical field [0001] The invention belongs to the field of catering waste sorting, and in particular relates to a large-material sorting system for catering waste. Background technique [0002] Catering waste has material characteristics such as high moisture content and high corrosiveness. In the process of recycling traditional food waste, it is necessary to classify materials through screening. At present, simple screens such as drum sieves are mostly used to sort large materials in food waste. . However, the existing sieves still have the following disadvantages for sorting large materials: 1. The sieve holes are easy to block (due to the strong viscosity of food waste materials and the presence of other complex interferences, the sieve holes are easy to block), resulting in a low screening and sorting efficiency. 2. The equipment occupies a large space and the cost is high; 3. It is difficult to clean up after the material is blocked, and the labor intensity is high....

Problems solved by technology

However, this patent achieves the separation of substrate and floating material (suspended material and floating material) in the sorting tank by directly omitting the screen. Although the separation of food waste is realized to a certain extent, the screen is avoided. However, on the one hand, the degree of separation is not thorough enough, it can only separate the floating material and the sinking bottom, and there is a problem that the sinking heavy objects such as large bones, broken bowls, and broken dinner plates cannot be sorted out, and cannot Thoroughly sort out the large material and the small material or viscous base material that adheres to the large material. On the other hand, after the screen is omitted, the food waste is completely separated by the stirring plate and the pushing plate, and the efficiency itself is excellent. Low, unable to quickly sort and stratify, the faster the speed, the better the sorting effect will be.
