Background technique

At present, the filter tanks used to treat cooling water and waste water mostly adopt rotary disc filter tanks or cross-flow filter tanks, such as the Chinese invention patent "A Filter Pool" with application number 200910097605.6 (publication number CN101549222A). A filter pond of the cross-flow filtration type is disclosed. It includes a square pool body, a multi-piece unit filter element arranged in the pool body, a first partition, a second partition, and a third partition connected in sequence in the pool body. The first partition is erected at the end of the water outlet and connected to multiple Between the ends of the unit filter element, the second partition is supported on the bottom of the multi-piece unit filter element and has a distance from the bottom of the pool body. The filter element holder in each unit filter element includes a base plate and a frame-type side plate, filtering The medium is tiled on the outer surface of the frame-type side plate, and at least one clean water outlet is opened on the base plate at the bottom, and a clean water inlet is opened on the second partition corresponding to each clean water outlet. Compared with the rotary disc filter, the cross-flow filter has a great improvement in structure and principle, solves the problem of high energy consumption in the rotary filter, and has a more significant sewage treatment effect.

After a long time of filtration in the cross-flow filtration filter tank, a lot of silt will settle at the bottom of the filter area. If the silt is not cleaned in time, it will block the filter medium, thereby reducing the filtration efficiency and affecting processing effect. Therefore, it is necessary to clean up the sludge at the bottom of the pool body in time.

In order to further enhance the sewage discharge effect, there are two third horizontal conveying pipes and two second vertical conveying pipes.

Because there is silt deposited on the bottom of the pool body, the bottom of the pool body will be high and low. Therefore, as a further improvement, the suction pan can be movably arranged next to the bottom of the sludge riser, and the outlet of the suction pan It is connected to the sludge riser through a hose. This avoids the rigid contact between the suction pan and the bottom of the pool body, preventing damage to the suction pan and other devices.

Various existing technologies can be used for the movable arrangement of the mud suction pan at the bottom of the sludge riser, such as being arranged in a form that can be rotated or moved up and down through a connecting plate.

As a further technical improvement, considering the simplicity of the process, the bottom end of the sludge riser is open, the suction pan is directly connected to the bottom of the sludge riser, and the outlet of the suction pan is directly connected to the sludge lift The opening at the bottom of the pipe is connected. When working, there is always a certain distance between the bottom of the mud suction pan and the bottom of the pool, so that accidents such as collisions will not occur, and the mud discharge function is guaranteed while ensuring the safe operation of the equipment.

The support that can walk longitudinally on the top of the pool body can adopt various existing technologies. In order to make the structure simpler and easy to implement, the support can be a motor-driven frame, and, on the top of the pool body, two There is a pair of rails arranged longitudinally along the side. The rollers in the frame walk on the rails driven by the motor. The motor is fixed on the top of the L-shaped sewage pipe. The motors all move with the frame.

Compared with the prior art, through the cleaning device of the utility model, the sludge deposited on the bottom of the pool body can be cleaned in time, and the structure is simple, the operation is convenient and the cleaning effect is good.
