Rotary grille cleaning machine

Rotary grille cleaning machineIt is a specialized water treatment equipment that can continuously and automatically intercept and remove various shaped impurities in fluids, and can be widely used in urban sewage treatment. The water supply industry, power plant inlet, and can also serve as front-end screening equipment in wastewater treatment processes for industries such as textiles, food processing, papermaking, and leather.

Working Principle:

According to the direction of water flow, the rake chain is similar to a grille, and the clearance between the rake teeth assembled on the rake chain shaft can be selected according to the usage conditions. When the rake teeth separate solid suspended solids in the fluid, it can ensure smooth flow of water. The entire work process can be continuous or intermittent.

Performance characteristics:

1. Compact structure, good overall performance, large water flow area, stable and reliable operation.

2. Simple operation, good cleaning effect, high efficiency, and long lifespan.

3. Easy to maintain, there are no fixed screws on the underwater part of the grille.

4. The grid rotation cycle, slag removal, and cleaning work are fully automated.

5. It has control functions such as automatic, jog, emergency stop, and cut-off, which facilitate operation and maintenance.

6. Each cleaning machine is equipped with a set of control box (indoor), all electrical components are made of domestic products, and PLC interfaces can be reserved according to user requirements.

7. Equipped with mechanical and electrical dual overload protection devices.

A A 、 Mechanical protection measures: A safety pin is installed in the transmission sprocket, which can instantly cut off the safety pin in case of overload to prevent damage to the transmission components.

B B 、 Electrical protection: Overcurrent protection is installed in electrical design to ensure effective protection of the motor from burning out in the event of equipment failure.

8. The chain of the cleaning machine is made of stainless steel material, and the small wheel of the chain is also made of stainless steel material; The underwater guiding part of the chain adopts a sliding track method, which does not require lubricating oil, making the chain less likely to be stuck by dirt.

9. The driving device is equipped with a protective cover, which not only meets the requirements of outdoor installation, but also facilitates inspection and maintenance;

10. A chain plate is installed between the chain and the rake teeth, forming a closed structure with the angle steel of the water blocking edge of the equipment, making the rake chain a closed chain, thereby preventing garbage from entering the machine's running track and preventing chain infarction and other faults;

11. When the toothed rake chain reaches the rear of the equipment, relative displacement occurs between the toothed rakes, performing self-cleaning motion, and the slag falls into the slag trolley. Therefore, there will be no blockage, so the daily maintenance workload is minimal and there will be no dead corners where dirt accumulates at the bottom of the grille.

12. When installing the equipment, seal the two sides in contact with the ditch wall with rubber sealing tape and fix them with steel pressure strips; There is a flat plate and rubber sealing tape in front of the bottom rake chain to achieve sealing between the equipment and the civil engineering, preventing the leakage of impurities in the water.

13. There are maintenance holes on both sides of the upper part of the equipment. Even if the rake teeth and other components are damaged due to large debris, they only need to be replaced on the work platform without underwater maintenance, which does not affect the water flow rate.
