Product description

1. Brief introduction of peripheral drive mud scraper

Peripheral drive mud scraper is a commonly used sedimentation tank mud scraping equipment in urban water plants and urban sewage treatment plants. Adopt middle water inlet, mud drain, and peripheral drain to ensure uniform water flow.

2. Advantages of peripheral drive mud scraper

1. The working bridge adopts a truss structure, which is simple, beautiful and light.

2. The maintenance is simple and convenient, and the operating cost is low. A siphon pipe is usually used to discharge the sludge from the sludge collecting tank to the central sludge discharge pipe without dynamic sealing to avoid short flow of supernatant liquid.

3. It adopts a new type of sludge discharge regulating valve, which is reliable in operation, convenient to use, and guarantees the concentration of sludge.

4. Multiple choices of transmission reducer: adopt shaft-mounted type, simple and compact structure, convenient for maintenance; adopt cycloidal pinwheel reducer, which is inexpensive and good-quality, and has high transmission efficiency.

5. According to the needs of users, the material of the travel wheel surface can be engineering rubber wheels (standard configuration), steel wheels, nylon wheels, and polyurethane wheels.

6. The electrical components are all outdoor type, which can be controlled randomly and remotely.

7. The equipment can be manufactured according to the user's specific size, and can provide flat bottom pools, inclined bottom pools and mud scrapers with large flat nozzle suction mouths that do not require mud collectors. The parts in contact with water can be made of stainless steel.

3. Main performance of peripheral drive mud scraper

1. Scraping mud at the bottom of the pool and skimming the slag on the water surface. The driving device adopts a shaft-mounted gear reduction motor and a direct connection transmission with an active roller, which has a compact structure and high mechanical efficiency.

2. Parallel dislocation line scraper, good continuity and high mud collection efficiency. There is a rubber scraper at the bottom of the stainless steel scraper to ensure that the scraping mud is completely clean and there will be no floating mud phenomenon.

3. The bottom slope ratio of the pool is 1:10, and the sludge resistance when scraping mud is negligible. Special hinge support structure, strong overload capacity.

4. The main beam is made of square steel with high structural strength. It adopts the hot-dip galvanizing and spraying finish process, which has strong anti-corrosion performance.

5. Simple operation and remote control can be realized.

4. Application of peripheral drive mud scraper

The peripheral drive mud scraper is mainly used in the primary sedimentation tank and the secondary sedimentation tank of urban water plants and sewage treatment plants. The product series range from DN20m-DN35m in diameter to various specifications, which can meet the sludge removal of sedimentation tanks with different treatment capacities.

5. Maintenance skills of peripheral drive mud scraper

1. Keep the oil mark position of the reducer lubricating oil when the mud scraper is running, and fill the roller bearing with oil once a month.

2. Check whether the connection of water parts is loose.

3. Check the seal of the transmission device.

4. Check the brushes of the collector.

5. Check the corrosion of various underwater parts, and replace the rubber scraper when it is severely worn and corroded.

6. Reapply anti-corrosion paint during overhaul.

7. When the mud scraper is running, attention should be paid to the changes in the amount of sewage and the degree of pollution.

8. If it is necessary to stop and drain the fault, stop discharging sewage into the pool, and then discharge the sewage after the fault is eliminated, and then drive again.
