Description

Technical Field

[0001] The present application relates to the field of sludge fermentation, and in particular, to a sludge fermentation tank that is easy to clean. Background Art

[0002] With the development of economy, the amount of sludge generated in life and production process is also increasing year by year, so it is necessary to treat the sludge. Sludge treatment is the process of reducing, stabilizing and harmless treatment of sludge. The higher the degree of sewage treatment, the more sludge residue will be produced and need to be treated. Sludge fermentation is an important method of sludge treatment. Through sludge fermentation, the substances and energy in the sludge can be greatly utilized, which not only reduces sludge pollution but also prevents the waste of resources.

[0004] In this regard, the Chinese patent application number is CN201921447253.8, which discloses an improved sludge fermentation tank. Through the cooperation of the first adjusting motor, the first screw rod, the first connecting piece, the cross bar, the second adjusting motor, the second screw rod and the second connecting piece, the liquid storage barrel is driven to move forward and backward and left and right in the horizontal direction, so that the microbial agent is evenly sprayed on the sludge, preventing the accumulation of some microbial agents, thereby increasing the fermentation efficiency. In addition, through the cooperation of the cleaning motor, the cleaning shaft and the cleaning plate, the residual sludge in the fermentation tank is cleaned to the discharge pipe, which facilitates the rapid cleaning of the residual sludge and reduces the labor of the user.

However, during the cleaning process, due to the low height of the cleaning plate, some sludge will still remain on the inner wall of the fermentation tank, thereby reducing the cleaning effect and the practicability of the device.
