Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to a tooth rake grille cleaning machine. Background Art

[0002] The tooth rake screen cleaner is a special water treatment equipment that can automatically and continuously intercept and remove various shapes of debris in the fluid. A set of rotating screen chains is assembled by a unique rake tooth. Driven by the motor reducer, the rake chain performs a rotating motion in the opposite direction of the water flow. When the rake chain runs to the upper part of the equipment, due to the guidance of the groove wheel and the curved rail, a relative self-cleaning motion is generated between each set of rake teeth, and most of the solid matter falls by gravity. The other part relies on the reverse movement of the cleaner to clean up the solid debris stuck on the rake teeth. In terms of the direction of water flow, the rake chain is similar to the screen, and the rake gap assembled on the rake chain shaft can be selected according to the use conditions. When the rake teeth separate the solid suspended matter in the fluid, the water flow can be guaranteed to flow smoothly.

[0003] In the use and operation of the fully automatic operation mode, the tooth rake screen cleaner and the shaftless screw conveyor press have brought convenience and reduced the labor and material input caused by the workload. After a long period of operation practice, the following problems were found to be urgently solved:

[0004] 1. During operation, the tooth rake screen cleaning machine may have strong adhesion due to the complex composition of sewage and dirt it contacts, causing the screen residue to accumulate and adhere to the tooth rake.

[0005] 2. The silo opening and distance between the tooth rake screen cleaner and the conveyor press are unreasonable, which will cause the solid waste dropped by the cleaner to adhere to the wall of the silo and require manual intervention and cleaning.

[0006] 3. After squeezing, there will be residual sewage with sticky components in the silo of the shaftless screw conveyor and press, and nodules and residual waste residues will form on the wall of the silo, affecting the use effect of the conveyor. In addition, some larger particles of solid waste will not be decomposed in time due to drying, causing blockage of the silo outlet.

[0007] 4. At the interface between the silo and the sedimentation press outlet, the solid and liquid cannot be completely separated because the sedimentation press outlet is gravity squeezed. In this process, a certain amount of sedimented garbage will flow out with the sewage and form lumps in the drainage hole and below it, which cannot flow into the sewage pool, causing blockage and requiring frequent cleaning. Therefore, designing a tooth rake grille cleaning machine that can achieve rapid cleaning and flushing and reduce garbage residue has become a technical problem that needs to be solved urgently by those skilled in the art.
