Background

In the existing organic matter aerobic roller fermentation process, a sealing device between a front fixed end plate and a rotatable roller body is fixed, and simple replacement and maintenance cannot be carried out from the outer side of equipment. Along with the increase of the service life of the roller, the sealing material at the position becomes thinner and thinner along with the play extrusion and the abrasion of the roller, and when the thickness of the sealing material is abraded to a certain degree, the material in the cylinder leaks out of the cylinder from the sealed gap, so that the sealing failure is caused. After the sealing is failed, the micro negative pressure environment in the roller is not favorably maintained, and the scattered materials can emit unpleasant odor to cause harm to the surrounding environment.

In order to solve the problems, the original aerobic roller needs to be shut down and overhauled after being used for a period of time, and because the sealing plates at two sides contacting with the sealing material are all whole fixing plates, when the sealing material is damaged, the sealing material cannot be repaired from the outside, and only after the sealing material is shut down and the material in the roller is emptied, a maintenance worker enters the interior of the roller to replace the sealing material.
