Organic fertilizer high-speed aerobic fermentation machine

Abstract

The invention relates to an organic fertilizer high-speed aerobic fermentation machine, belonging to the technical field of fermentation machines. The organic fertilizer high-speed aerobic fermentation machine comprises a PLC control center, and a fermentation tank, a loading mechanism, a feeding mechanism, a ratchet driving mechanism, a weighing mechanism, a dual-channel air intake mechanism, a discharging mechanism and a purifying mechanism which are connected with the PLC control center, wherein the front side edge of the top part of the fermentation tank is connected with the feeding mechanism, the feeding mechanism is butted with the loading mechanism, and the loading mechanism is installed on the front side of the fermentation tank; the right side edge of the top part of the fermentation tank is provided with an exhaust gas outlet, the exhaust gas outlet is connected with the purifying mechanism, and the purifying mechanism is installed on the right side of the fermentation tank;the oxygen and temperature required for aerobic fermentation of organic matters in the fermentation tank are effectively controlled by means of the dual-channel air intake mechanism and a temperaturecontrol device in the fermentation tank; fully aerobic fermentation of the organic matters is effectively controlled by means of the weighing mechanism; and the exhaust gas generated in the aerobic fermentation process is effectively purified by means of the purifying mechanism.

Description

technical field [0001] The invention relates to a high-speed aerobic fermenter for organic fertilizers, in particular to a fermenter for high-speed aerobic fermentation of organic matter, which belongs to the technical field of fermenters. Background technique [0002] Since the fermentation of livestock manure, catering residues or sludge requires stable oxygen and temperature, in the existing fermentation device, oxygen is sent into the fermentation tank through a pipeline for gas supply, and the oxygen cannot be fully contacted during the fermentation process, resulting in a long fermentation time; Unstable temperature leads to long fermentation time and insufficient aerobic fermentation of organic matter; during the process of aerobic fermentation of organic matter, a large amount of high-concentration malodorous exhaust gas will be generated, which will be directly discharged into the atmosphere and form a large amount of aerosol, which not only seriously threatens the o...

Problems solved by technology

[0002] Since the fermentation of livestock manure, catering residues or sludge requires stable oxygen and temperature, in the existing fermentation device, oxygen is sent into the fermentation tank through a pipeline for gas supply, and the oxygen cannot be fully contacted during the fermentation process, resulting in a long fermentation time; Unstable temperature leads to long fermentation time and insufficient aerobic fermentation of organic matter; during the process of aerobic fermentation of organic matter, a large amount of high-concentration malodorous exhaust gas will be generated, which will be directly discharged into the atmosphere and form a large amount of aerosol, which not only seriously threatens the on-site staff The health and safety of the environment, and it is difficult to eliminate the accumulation in the atmosphere, resulting in the odor. The existing odor treatment technology mainly refers to the chemical unit operation technology, such as absorption, adsorption, oxidation, combustion, etc., and the efficiency of such odorous waste gas treatment can reach 80% %-90%, but it is not suitable for the treatment of high-concentration malodorous waste gas; resulting in the inability to realize fully automatic control of organic fertilizer feeding, feeding and weighing, full aerobic fermentation and waste gas treatment and discharge, etc.
