Earthworm stereoscopic circulating breeding equipment for treating sludge

Abstract

The invention discloses earthworm stereoscopic circulating breeding equipment for treating sludge. The earthworm stereoscopic circulating breeding equipment for treating the sludge comprises an elevator, a plurality of earthworm breeding boxes and a sludge conveying mechanism, wherein the earthworm breeding boxes are sequentially hinged to the elevator; the sludge conveying mechanism comprises a hopper, a conveyor, a rotating support frame, a movable rack with rollers and a track; the hopper is arranged on the conveyor; a discharging opening of the hopper communicates with a feeding opening ofthe conveyor; the rotating support frame is connected to the lower portion of the conveyor; the rotating support frame rotates on the movable rack; the conveyor is driven to convey materials into theearthworm breeding boxes by rotation; the movable rack rolls on the rack through the rollers; and the length direction of the track is parallel to the length directions of the earthworm breeding boxes. The earthworm stereoscopic circulating breeding equipment for treating the sludge is simple in structure, small in occupation area and high in earthworm breeding efficiency; and the sludge can be treated effectively.

Description

Technical field [0001] The invention relates to the technical field of earthworm processing sludge, in particular to an earthworm three-dimensional circulation breeding equipment used for sludge treatment. Background technique [0002] A large amount of sludge will be produced in the process of sewage treatment. The organic components in the sludge are mainly composed of organic matter adsorbed by microorganisms. These microorganisms are mainly heterotrophic aerobic bacteria, which have strong decomposition and transformation of organic matter. It is an inorganic function, but the living environment of microorganisms will change after the sludge is dehydrated. The microorganisms are in an endogenous respiration state, and the diffusion of metabolites is difficult, resulting in poor stability of the sludge. When the oxygen supply is insufficient, it is very easy to decompose and smell. Produce secondary pollution to the environment. The current sludge treatment methods mainly inc...

AI Technical Summary

Problems solved by technology

[0003] Earthworm breeding is mainly realized through box-type culture beds, pool-type culture beds and trough-type culture beds. The cost of box-type culture beds is low and easy to build. It is a more commonly used method at present, but it is inconvenient to operate and the bearing capacity of the bed surface is limited. , the range of earthworm activities is small, and the earthworm material on the four walls is easy to dry out; the pond-type culture bed is suitable for large-scale cultivation, but the bed body occupies a large area, serious waste of water resources, easy to produce anaerobic dead ends, and earthworms grow slowly; the trough-type culture bed Distributed in the field, the temperature is difficult to control, the waste of water resources is serious, and the phenomenon of earthworm escape is easy to occur, which seriously affects the production of earthworms
