Disc screen for kitchen waste impurity removal in hermetia illucens cultivation

Abstract

The invention discloses a disc screen mainly for a kitchen waste impurity removal process in hermetia illucens cultivation. The disc screen mainly comprises anti-winding smooth star-shaped disc sheets, square center shafts and circular shaft sleeves. According to the smooth star-shaped disc sheets, the diameter of a protruding part is 250-300 mm, the diameter of an inner ring is 40-60 mm smaller than that of the protruding part, the thickness of the disc sheets is 10-20 mm, 6-8 smooth protrusions are arranged on each star-shaped disc sheet, and scraping teeth are arranged on one of the protrusions and used for preventing a small number of objects from being possibly wound; and the interiors of the smooth star-shaped disc sheets and the shaft sleeves are of square structures and are connected in series through the square shafts, and each square shaft is provided with 10-16 sets of discs which are sequentially connected with the shaft sleeves in a staggered mode. When the disc screen runs, to-be-treated materials cannot be wound around the disc, the shaft sleeves or the edges of the shaft, and impurities such as plastic and large bones in kitchen waste generated during hermetia illucens breeding can be efficiently screened out.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to a disc sieve used for removing impurities from kitchen wastes raised by black soldier flies. Background technique [0002] Food waste treatment is an important part of the harmless treatment of domestic waste. Due to its characteristics of organic matter, high moisture content, and easy breeding of pathogenic microorganisms, food waste cannot be landfilled or incinerated together with ordinary domestic waste. Garbage is disposed of separately. At the same time, because of the high content of biomass organic matter and nutrients in kitchen waste, people have invented a method to treat kitchen waste by breeding black soldier flies. The use of food waste to breed black soldier flies can not only consume the biomass organic matter in the food waste almost completely through the metabolism of the black soldier flies, effectively prevent the growth of various pathogen...

AI Technical Summary

Problems solved by technology

[0004] In the process of separating food waste, disc sieve separation is a relatively efficient separation method. However, due to the disc size and structure of the existing disc sieve, it is easy to cause serious problems such as entanglement when separating flexible debris such as plastics. , seriously affecting the efficiency and stability of impurity removal

The existing disc sieve needs to regularly remove the related impurities entangled on the disc sieve, the removal efficiency is low, and it is almost difficult to be directly applied to the process of removing impurities from the kitchen waste of black soldier fly breeding
