Efficient biogas digester for removing slag

Abstract

The invention discloses an efficient biogas digester for removing slag. The efficient biogas digester comprises an anaerobic fermentation tank; a tank cover is arranged at and matched with the top ofthe anaerobic fermentation tank; a mounting rack is arranged on the top of the tank cover; a bacteria hopper is arranged on one side of the mounting rack while a second exhaust pipe is arranged on theother side; a blanking pipe of the bacteria hopper and the second exhaust pipe are both communicated with the anaerobic fermentation tank; a positive and negative motor is arranged on the top of themounting rack; a disc is embedded on the tank cover; an output shaft of the positive and negative motor is in driving connection with the disc; an external shaft is arranged on the bottom of the disc.The efficient biogas digester for removing slag utilizes a stirring blade and a stirring rod to simultaneously mix the raw materials and bacteria in the anaerobic fermentation tank in the manner of dual overlapping stirring, so that the mixture can be more quickly and uniformly mixed. In the mixing process, a heating pipe and a heating wire are adopted for generating heat, so as to increase the temperature in the anaerobic fermentation tank, promote the activity of strains and accelerate the generation of methane.

Description

technical field [0001] The invention relates to the field of biogas production equipment, in particular to a high-efficiency biogas digester which is convenient for slag removal. Background technique [0002] As we all know, biogas is an energy-saving, environmentally friendly and economical green energy, which is widely favored. The production of biogas can deal with domestic waste, which is energy-saving and environmentally friendly. Biogas residue and biogas slurry can be used as green fertilizers for farmland fertilization, which can reduce chemical fertilizers. The usage amount can produce green organic vegetables and food. However, during the use of the existing biogas digesters, due to insufficient contact between the raw material and the bacterial material and the influence of the temperature of the fermentation environment, the biogas production efficiency is low, and the cleaning of the biogas residue in the later stage is also troublesome. [0003] Therefore, it ...
