Biogas digester reloading device suitable for reloading of low-temperature biogas digesters

Abstract

The present invention discloses a biogas digester reloading device suitable for reloading of low-temperature biogas digesters. The biogas digester reloading device comprises a foundation, a heating cavity and a gear cavity are formed in the foundation, a biogas digester is arranged in the foundation, a fermentation cavity is formed in the biogas digester, a raw material tank is fixedly arranged onan upper end of the foundation, a feeding valve communicates with a lower end of the raw material tank, a lower end of the feeding valve communicates with a feeding cavity, and the device fishes up biogas residues in the biogas digester while conducts automatic reloading, pours the biogas residues on a feeding device, uses residual heat of the biogas residues to conduct initial heating of fed materials, improves an initial temperature of the fed materials entering the biogas digester, solves a problem that a biogas production effect of the biogas digester is affected by excessively low feeding temperature during feeding in winter, improves utilization of the biogas residues, also does not need manual residue removal, and eliminates potential safety hazards during the manual residue removal.

Description

Technical field [0001] The present invention relates to a low temperature suitable for biogas digester refueling refueling equipment, refueling relates digester art. Background technique [0002] Biogas digester is a manufacturing facility. [0003] Biogas is organic matter in an anaerobic environment, at a certain temperature, humidity, pH conditions, for use by microbial fermentation, a combustible gas produced. Since this gas was first discovered in swamps, lakes, ponds, so people call it biogas. [0004] Porcine, dung biogas fermentation feedstock, typically a year in the spring or autumn large refueling 1 or 2 times when fertilizer. Refueling should pay attention: If there is no holding facilities should not be large refueling in the winter season, or start a bad impact gas production effect. [0005] Digester carrying the discharge channel is discharged liquid slag usually only able to flow within the digester, biogas sludge agglomerates are retained in the digester over ti...

AI Technical Summary

Problems solved by technology

[0005] The discharge channel of the biogas digester usually only discharges the slag liquid that can flow in the biogas digester, and the agglomerated biogas residue accumulates in the biogas digester, which reduces the space for fermentation in the biogas digester and reduces the biogas production.

Only by regularly opening the biogas tank to manually clean the biogas slag, but manual removal of slag in the biogas tank has certain safety hazards, and the biogas slag in the biogas tank still has a high temperature, directly shoveling out the heat in the biogas slag is wasted, so this equipment is designed Solve the above-mentioned problems that the gas production effect is easily affected during refueling in winter and manual slag removal is required
