Description

Technical Field

[0001] The invention relates to an automatic feeding control method for kitchen waste treatment, belonging to the technical field of kitchen waste treatment. Background Art

[0002] The current process route for kitchen waste treatment is that the kitchen waste is transported to a crusher through a conveying equipment and crushed. The crushed kitchen waste is then transported to an extrusion dehydrator through a conveying equipment for slurry extrusion to separate the organic slurry and residue, and the organic slurry and residue are treated separately.

[0003] When kitchen waste is transported from the conveying equipment to the extrusion dehydrator for material extrusion, the conveying capacity of the conveying equipment and the processing capacity of the extrusion dehydrator often do not match, causing kitchen waste to overflow through the connection ports of various equipment. The overflow of kitchen waste not only brings unpleasant odor to the production workshop, but also makes it very difficult for workers to clean up. Summary of the invention

[0004] In order to solve the above problems, an object of the present invention is to provide an automatic feeding control method for kitchen waste treatment.

[0005] The objective of the present invention is achieved through the following technical solutions:

[0007] Perform a dehydrator operating condition test. If the dehydrator operating conditions are met, proceed directly to the next step; otherwise, shut down the bottom screw conveyor, crusher feed conveyor, crusher and dehydrator feed conveyor in sequence, and keep the dehydrator running until the dehydrator operating conditions are met before proceeding to the next step;
