The circulating tooth rake cleaning machine mainly consists of a frame, a driving device (motor reducer), two-side traction chains, guide sprockets, hook grids, Cleaning consists of rotating brush and on-site control box.

Tooth rake

Tooth rake is composed of many small tooth rakes connected to each other to form a huge rotating surface. It can remove slag thoroughly, cleanly, and operate flexibly and reliably. The tooth rake has sufficient strength and rigidity and will not cause bending of the connecting shaft or affect the smooth movement of the rake grid or dechain. The return rake grid after unloading is equipped with a practical and reliable dirt discharge suction nozzle to prevent dirt from adhering to it. The rake teeth are made of stainless steel or nylon.

Frame and frame guard

The frame and frame guard of the grille machine are welded with ordinary steel or stainless steel of considerable size to form a rigid support structure. . The frame and guard are continuously welded to prevent sewage from leaking out. The inside of the equipment frame is equipped with a traction chain circulating motion rail guide. Both sides of the frame are made of ordinary steel plates or stainless steel plates, which form the frame of the circulating tooth rake cleaning machine. Its cross-sectional size is sufficient to meet the maximum working load interception requirements. The gap between both sides of the rack and the grill well is protected from garbage by rubber sealing plates on both sides of the rack.

Rake chain

The rake chain is assembled from a unique set of rake teeth, with strong load-bearing capacity and minimal ring damage. The rake teeth run smoothly, the rake teeth are evenly set, easy to replace and have sufficient strength and rigidity. In order to prevent debris from entering the rake tooth traction chain, a closed traction chain is creatively designed, making the equipment operation more stable and reliable. The rake tooth ends are rounded, which can effectively remove debris and prevent it from returning to the sewage.

The upper part of the equipment is equipped with a cleaning device. This mechanism has flexible movement and adjustable position. It has good cleaning ability. It can remove a small amount of debris adhered to the rake teeth through the reverse rotation of the cleaning brush. to clean, no clogging will occur, and the daily maintenance workload is very small

Driving device

The driving device of the circulating tooth rake cleaning machine has a compact structure and is easy to adjust and maintain. convenient. The driving device is equipped with a chain tensioning mechanism and a mechanical overload device, and the safety factor of the chain is greater than. The driving device is flexible, stable and reliable, and has no abnormal noise.

The driving device is equipped with a protective cover. Its structure is convenient for maintenance and inspection and can meet the requirements of outdoor installation.

The driving shaft can withstand the load of bending moment and button moment at the same time. , the lubrication of bearings and all rotating parts of the equipment can be carried out automatically. The drive motor is grade insulated, , and the rated power of the motor is greater than the maximum actual power consumption of the grille.

Measures to prevent chain falling off

The falling off of the traction chain is generally caused by the horizontal movement of the conveyor chain and poor meshing of the sprocket teeth due to the chain being too long. First of all, during design, The pins on the inside of the conveyor chains on the left and right sides are designed as convex shoulders, and one end of the pin is fixed with a circlip. The conveyor chain will inevitably become longer due to working under tension for a long time. At this time, the tensioner should be adjusted to ensure the normal meshing of the chain drive and ensure the normal operation of the chain drive in the vertical direction.

Underwater rotating wheel

The underwater rotating wheel should be in the form of a guide roller to prevent the entanglement of screen debris in the structure.
