AI Technical Summary

Technical Problem

Existing anaerobic fermentation devices for livestock and poultry manure cannot effectively separate wastewater and manure, resulting in some nutrients in the mixture not being utilized or transformed during fermentation, thus affecting the fermentation effect.

Method used

Design an anaerobic fermentation tank including a sewage treatment tank and a fecal fermentation tank. The first filter screen separates the fecal matter into sewage and solid feces, which are treated separately. The pneumatic cylinder and scraper system maintain the permeability of the filter screen, and the reverse rotation of the stirring blades ensures that the anaerobic bacteria are in full contact with the feces.

Benefits of technology

It achieves efficient separation and targeted treatment of sewage and solid feces, improves fermentation effect, avoids resource waste and low treatment efficiency, and ensures the continuity and stability of the fermentation process.

Abstract

The utility model belongs to the technical field of livestock and poultry manure anaerobic fermentation, and particularly relates to a livestock and poultry manure anaerobic fermentation pool which comprises a box body, the box body is composed of a sewage treatment tank and a manure fermentation tank, the top side of the box body is fixedly connected with a supporting seat, the supporting seat is fixedly connected with a solid-liquid separation box, and the solid-liquid separation box is fixedly connected with a liquid storage tank. A first positioning groove is formed in the inner wall of one side wall of the solid-liquid separation box, a first inserting groove is formed in the other side wall of the solid-liquid separation box, and a first filter screen plate is inserted into the first through groove and the first positioning groove in a matched mode; according to the livestock and poultry manure fermentation device, before livestock and poultry manure is fermented, sewage and solid manure in the manure are separated through the first filter screen plate and enter the sewage treatment tank and the manure fermentation tank respectively, so that subsequent targeted treatment on the sewage and the manure is facilitated, and the problems of resource waste and low treatment efficiency caused by mixed treatment are solved; the manure fermentation treatment effect is greatly improved.
