Description

Cleaning device and cleaning method for organic fertilizer fermentation tank Technical Field The invention relates to the technical field of organic fertilizer production, in particular to a cleaning device and a cleaning method for an organic fertilizer fermentation tank. Background The organic fertilizer fermentation tank is core equipment for recycling organic wastes such as livestock manure, crop straws and the like. In the aerobic fermentation process, materials are easy to form a plate layer on the inner wall of the tank body, so that the heat exchange efficiency is reduced, ventilation is blocked, and the fermentation uniformity and the product quality are seriously affected. Therefore, the periodic cleaning of the inner wall of the fermenter is a key element to ensure the fermentation efficiency. The existing fermentation tank cleaning device is mainly divided into the following types (one) a fixed scraping plate device, wherein a rigid scraping plate is arranged on a rotating shaft and rotates along with the rotating shaft to scrape attachments on the inner wall of a tank body. The gap between the scraping plate and the tank wall of the device is fixed, so that the device cannot adapt to the ovality deformation or the local scaling thickness difference of the tank body, and the scraping is not clean or the scraping plate is blocked easily. Meanwhile, the scraping plate is in long-term rigid contact with the tank wall, abrasion is serious, and the service life is short. And (II) a rotary brush type cleaning device adopts a rotary brush to replace a rigid scraping plate, and cleaning is realized through flexible contact between bristles and the tank wall. Such devices typically secure the cleaning brush directly to the shaft or sleeve, with all the cleaning brushes rotating in the same direction with the shaft. The structure has the following defects that firstly, large unidirectional torque is generated by the same-direction rotation, the equipment is severely vibrated, the requirement on the strength of a frame is high, secondly, the cleaning track of bristles is single, materials are easy to push to one side to form accumulation, effective turning of the materials cannot be realized, thirdly, the pressing force of the bristles and the tank wall cannot be dynamically adjusted according to working conditions, the insufficient pressing force possibly occurs during high-speed rotation, the cleaning is not thorough, or the excessive pressing force aggravates the abrasion of the bristles during low-speed rotation, and the existing fermentation tank cleaning device has obvious defects in the aspects of a motion mode, self-adaptive adjustment capability and multi-brush collaborative operation. Disclosure of Invention Aiming at the defects existing in the prior art, the invention aims to provide a cleaning device and a cleaning method for an organic fertilizer fermentation tank, so as to solve the technical problems of incomplete cleaning coverage and low cleaning efficiency of the cleaning device in the prior art. In order to achieve the above purpose, the present invention adopts the following technical scheme: A cleaning device for a organic fertilizer fermenter, installed in the fermenter, the fermenter having a height direction, the cleaning device comprising: The upper frame body is arranged at the feeding end of the fermentation tank; the cleaning assembly is arranged on the frame body and extends into the fermentation tank, and comprises a rotating shaft and a plurality of cleaning brushes, wherein the cleaning brushes are obliquely arranged on the rotating shaft; The swinging assembly is arranged between the rotating shaft and the cleaning brush to change the working angle of the cleaning brush under the action of external force; the cleaning brush is meshed with the corresponding gears through the mounting cylinder. Further, the swing assembly includes: The mounting seat is connected with the rotating shaft; the near end of the connecting rod is hinged to the mounting seat, and the far end of the connecting rod is connected with the cleaning brush; The limiting rod is arranged in parallel with the connecting rod, and two ends of the limiting rod are respectively connected with the mounting seat and the cleaning brush; The swing block is movably arranged at one end of the limiting rod, which is close to the mounting seat.
