Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to a waste water and sludge separation device with a self-cleaning function. Background Art

[0002] Some production enterprises will generate a large amount of waste water during the production process. In the process of waste water treatment, the separation of sludge is an important treatment link. In this treatment process, the centrifugal separation method is mostly used. The centrifugal separation method sprays the waste water through a pipeline onto a high-speed rotating filter screen inside the treatment equipment. However, in this treatment process, although the waste water and sludge have been separated, due to the centrifugal force, the sludge will continuously accumulate on the inner wall of the filter screen, thereby gradually reducing the sludge separation efficiency of the equipment. At the same time, there may also be a situation where the sludge blocks the holes of the filter screen. Therefore, it is particularly important to provide a waste water and sludge separation device with a self-cleaning function to solve the above problems. Content of the Utility Model

[0030] Working principle: When performing sludge separation operation, first start the first motor 4 and the fourth motor 28, which drive the rotating rod 10 and the filter screen 23 to rotate. Then connect the external sewage pipeline to the wastewater interface 5. The sewage flows through the wastewater downpipe 3 under the action of the stirring blade 601 and is sprayed onto the inner wall of the rapidly rotating filter screen 23 through the diversion cover 8. At this time, the sludge is blocked on the inner wall of the filter screen 23 and accumulates on the inner surface of the filter screen 23. Then, by controlling the rotation of the second motor 13, the rotating rod 10 is driven to rotate, so that the side of the scraper 1001 gradually approaches the inside of the filter screen 23, and the accumulated sludge is scraped into the sludge tank 24 at the bottom. The sludge is discharged from the sludge outlet 25 through the rotating auger 602. At the same time, the wastewater passes through the filter screen 23 and enters the V-shaped water tank 29 and is discharged through the drain port 30 to enter the next process. When stopping the sludge separation operation, the third motor 22 can be started, which drives the screw 16 to rotate, and then the slider 15 makes a vertical displacement, driving the annular pipeline 17 and the nozzle 18 to make a vertical displacement. At the same time, the water inlet hose 19 is automatically drawn out from the water inlet hose automatic storage box 20, and the water sprayed through the nozzle 18 is used to clean the filter screen 23. At the same time, control the rotation of the second motor 13, which drives the rotating rod 10 and the brush plate 1002 to rotate, so that the brush plate 1002 gradually approaches the inner wall of the filter screen 23 and performs auxiliary cleaning operation on it.
