Description

Technical Field

[0002] Sewage treatment is the top priority in environmental protection. At present, the commonly used sewage treatment method generally adopts magnetic coagulation treatment. Magnetic coagulation sedimentation is to add magnetic powder to the ordinary coagulation sedimentation process to make the pollutants flocculate and combine into one, so that the generated flocs are denser and stronger, thereby achieving the purpose of high-speed sedimentation. After the sewage is precipitated in the sedimentation tank, the precipitated water is discharged through the pump body, and the precipitated sediment is discharged through the sludge pump. When the precipitated water is discharged, the action of the pump will cause part of the sediment to accumulate at the drain outlet, which is easy to cause blockage of the drain outlet, and then lead to poor drainage. In addition, a certain amount of sediment will accumulate on the inner wall and bottom surface of the sedimentation tank, which cannot be discharged through the sludge pump, and it is inconvenient to clean.

In addition, when the support driving plate moves downward, the sediment on the inner wall of the sedimentation tank can be scraped off and accumulated at the bottom of the tank under the action of the convex ring plate under the inclined surface.

[0015] 2. After the water in the sedimentation tank is discharged, the sediment can be discharged. After the sedimentation is discharged, a certain amount of sediment will accumulate at the bottom of the tank. Start the electric telescopic rod to move the support driving plate upward. As the support driving plate moves upward, the top bar will contact the inclined movable block, which will push the inclined movable block to move upward. As the inclined movable block moves upward, the two movable material plates in the sedimentation tank will move toward each other under the action of the articulated matching rod, so that the sediment at the bottom of the tank will be accumulated in the middle position of the sedimentation tank, which is more convenient for the staff to clean the bottom of the tank.

[0016] 3. As the inclined movable block moves upward, the connecting block will be inserted into the connecting slot. As the inclined movable block moves upward, it will also drive the movable plug rod to move. As the movable plug rod moves upward, it will drive the movable matching block to move under the action of the connecting channel, and then drive the inclined movable block to move and separate it from the matching top strip, so that the linkage matching strip can be reset under the action of the second connecting spring.

[0038] A sediment limitation method comprising the following steps: Step 1: Moving the support and driving plate 2 downward: Starting the electric telescopic rod 17 to drive the support and driving plate 2 to move downward into the sedimentation tank 11; Step 2: Closing the support and driving plate 2: As the support and driving plate 2 moves downward, the movable matching plate 4 is driven to move relative to the support and driving plate 2, so that the water-permeable through hole 41 is in a closed state, thereby closing the support and driving plate 2 and limiting the sediment; Step 3: Scraping down the sediment on the inner wall of the sedimentation tank 11: The sediment on the inner wall of the sedimentation tank 11 is scraped down to the bottom of the tank under the action of the lower convex ring plate 28 of the inclined surface; Step 4: Concentration of sediment at the bottom of the pool: The support driving plate 2 moves upward to drive the movable material plate 6 to move toward each other to concentrate the sediment, so as to facilitate its cleaning.

[0039] After the sewage is precipitated, the electric telescopic rod 17 is started to move the support driving plate 2 downward. In the process of moving downward, the arc pushing surface 24 will contact the inclined movable block 53, so that the inclined movable block 53 will be pushed to move under the action of the arc pushing surface 24, so that the arc pushing surface 24 can smoothly move over the inclined movable block 53 downward, and the support driving plate 2 is inserted into the sedimentation tank 11. Under the action of the convex ring plate 28 under the slope, the sediment on the inner wall of the sedimentation tank 11 can be scraped to the bottom of the tank, and water passes through the water-permeable through hole 41. When the support driving plate 2 is inserted into the sedimentation tank 11, the sediment on the inner wall of the sedimentation tank 11 can be scraped to the bottom of the tank, and water passes through the water-permeable through hole 41. Before the supporting and driving plate 2 moves down to the working position, as the supporting and driving plate 2 moves down, the connecting movable bottom block 33 will contact the matching supporting plate 16. At this time, the connecting movable bottom block 33 will no longer move, and the matching plate 4 will be pushed to move under the action of the matching linkage rod 34, thereby making the water-permeable through hole 41 closed, so that the sediment can be restricted under the supporting and driving plate 2. At this time, the supporting and driving plate 2 is under the drain outlet, so that there will be no sediment blocking the drain outlet during drainage. When the water is drained, the sediment is discharged. The sludge pump 16 is used to pump the sludge from the bottom of the pool until a small amount of sediment at the bottom of the pool cannot be discharged by the sludge pump. At this time, the electric telescopic rod 17 is started to move the supporting driving plate 2 upward. During the upward movement, the matching top bar 22 will contact the inclined movable block 53, so that the inclined movable block 53 will be driven to move upward under the action of the matching top bar 22. As the inclined movable block 53 moves upward, the linkage matching bar 5 will also be driven to move upward. In this way, under the action of the hinged matching rod 59, the movable material plate 6 in the sedimentation tank 11 will be driven to move toward each other, and the sediment at the bottom of the pool can be sunk to the bottom of the pool. The middle position of the sedimentation pool 11 is pushed to facilitate the staff to clean the sediment at the bottom of the pool. When the inclined movable block 53 moves upward, the connecting block 78 will be inserted into the connecting slot 55, and then the linkage matching strip 5 can drive the movable plug rod 73 to move upward. As the movable plug rod 73 moves upward, it will drive the movable matching block 7 to move under the action of the connecting channel 194, and then drive the inclined movable block 53 to move, so that the matching top strip 22 is separated from the inclined movable block 53, so that the linkage matching strip 5 is reset under the action of the second connecting spring 58.
