Telescopic finger-plucking type anaerobic fermentation raw material slagging machine

Abstract

Telescopic finger-type anaerobic fermentation raw material deslagging machine. Including the bracket, the outer shell, the cylindrical shaft installed through the spoke disc in the outer shell, one end of the cylindrical shaft is connected with the driving mechanism, the eccentric crankshaft is installed in the cylindrical shaft through the inner spoke disc, one end is fixed with the outer shell, and a set of bushings is set on it. One finger is fixed on the shaft sleeve, and the finger goes out along the finger sleeve fixed on the cylinder shaft. A sieve plate and a deflector are arranged under the cylinder shaft. The end of the deflector is connected to the discharge port. There is a slag outlet, and a feed inlet and a water inlet are arranged above the outer casing. The livestock and poultry manure containing weeds and animal cilia, after dilution, realizes the separation of dregs and livestock manure under the action of a series of three consecutive actions of grasping, moving and throwing by the telescopic finger, thus realizing the separation process. The invention has a simple structure, does not waste water resources, improves the purity of fermentation raw materials, eliminates the hidden dangers of blockage of material inlet and outlet pipelines in biogas projects and crusting or deposition of raw materials in ponds, and is beneficial to the smooth operation of the entire biogas project.

Description

【Technical field】: [0001] The invention belongs to the field of environmental protection and relates to a pretreatment device for anaerobic fermentation of livestock and poultry manure. 【Background technique】: [0002] In biogas projects and general rural sewage treatment processes, the main raw material for anaerobic fermentation is general livestock and poultry manure, which is usually mixed with more weeds, straw and animal cilia. [0003] Weeds and straw are rich in long and difficult-to-decompose cellulose and hemicellulose. These substances are easy to block the feed pipeline and decompose slowly after the raw materials are put into the anaerobic reactor. They are easy to float and crust and block the gas path. And the discharge pipeline, and reduce the gas storage space of the anaerobic reactor, which brings many unnecessary troubles to the biogas production and seriously affects the normal operation of the entire system. The usual solution is to stack and retting th...

AI Technical Summary

Problems solved by technology

[0003] Weeds and straw are rich in long and difficult-to-decompose cellulose and hemicellulose. These substances are easy to block the feed pipeline and decompose slowly after the raw materials are put into the anaerobic reactor. They are easy to float and crust and block the gas path. And the discharge pipeline, and reduce the gas storage space of the anaerobic reactor, which brings many unnecessary troubles to the biogas production and seriously affects the normal operation of the entire system

The usual solution is to stack and retting the slag-containing raw materials for a long time before anaerobic fermentation to degrade cellulose and hemicellulose, but this will delay the feeding time of raw materials, and cannot feed in time, reducing the utilization rate, resulting in a certain degree of environmental pollution

[0004] The feces of livestock and poultry farms contain a large amount of animal cilia. These cilia are long and thin, hard to corrode and difficult to decompose. They are easy to block the feed, discharge and circulation pipes of the feed liquid. After entering the anaerobic reactor, they are easy to deposit and shrink. The effective volume of the reactor also brings great inconvenience to the effective use of the anaerobic reaction system, reduces the efficiency of the entire system, and causes unnecessary economic losses
