Description

Technical Field

[0001] The utility model relates to the technical field of cleaning devices, and particularly relates to a residue cleaning device for a precipitation reaction tank. Background Art

[0002] A precipitation reaction tank is an essential infrastructure in the sewage treatment process. By using the action of gravity, the suspended substances in water can automatically settle, so as to remove the suspended substances in water. However, after long-term use, a large amount of dirt, silt and other residues will remain at the bottom of the precipitation reaction tank. To keep the precipitation reaction tank clean and the water treatment quality, it is necessary to regularly clean the inside of the precipitation reaction tank.

[0003] Traditionally, for cleaning the residues at the bottom of the tank, it is usually necessary for workers to hold a sludge scraping board and enter the tank to scrape up the residues, then put the scraped residues into a bucket for collection, and then lift the bucket out and pour out the residues inside. This cleaning method is cumbersome and requires excessive manual intervention, making it difficult to accelerate the cleaning speed of the residues at the bottom of the tank. Content of the Utility Model

[0004] The purpose of the utility model is to provide a residue cleaning device for a precipitation reaction tank in view of the defects and deficiencies of the prior art.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A residue cleaning device for a precipitation reaction tank, comprising a tank body, a water storage cavity opened on the tank body, a drain pipe arranged on the side end face of the tank body and communicated with the water storage cavity, and further comprising a cleaning opening opened on the side end face of the tank body and communicated with the water storage cavity for discharging residues outwards, a moving plate slidably arranged on the bottom surface of the tank body inside the water storage cavity and capable of moving closer to or away from the cleaning opening end under the drive of an external force, a cleaning scraper arranged on the lower end face of the moving plate and abutted against the bottom surface of the tank body for pushing the residues on the inner bottom surface of the tank body outwards through the cleaning opening when the moving plate moves closer to the cleaning opening end, a driving device arranged between the tank body and the moving plate for driving the moving plate to move closer to or away from the cleaning opening end in the water storage cavity, a plugging plate detachably arranged on the tank body inside the cleaning opening for closing or opening the cleaning opening, and a fixing device arranged between the plugging plate and the side end face of the tank body for fixing or releasing the fixing of the plugging plate in the cleaning opening when the plugging plate closes the cleaning opening. The bottom surface of the cleaning opening is parallel to the bottom surface of the water storage cavity.

[0006] Further improvement is that: the end face of the cleaning scraper close to the cleaning opening is an inclined surface.

[0007] Further improvements are as follows: The driving device includes a rotating screw rod rotatably arranged in the water storage cavity on the pool body, a linkage plate threadedly connected to the rotating screw rod in the water storage cavity, a guiding member arranged between the linkage plate and the pool body in the water storage cavity for restricting the rotation of the linkage rod when the rotating screw rod rotates so that the linkage plate moves on the rotating screw rod, a servo rotating motor with a fixed end arranged on the side end face of the pool body and an output end connected to the rotating screw rod, and a linkage rod arranged between the lower end of the linkage plate and the upper end of the moving plate.

[0008] Further improvements are as follows: The guiding member includes two guiding rods symmetrically arranged on both sides of the rotating screw rod on the pool body in the water storage cavity, and guiding holes formed in the linkage plate and in clearance fit with the two guiding rods respectively.

[0009] Further improvements are as follows: Sealing blocks for sealing the cleaning opening are respectively arranged on the upper and lower end faces and the left and right end faces of the plugging plate.

[0010] Further improvements are as follows: The sealing block is a rubber block.

[0011] Further improvements are as follows: The fixing device includes a mounting seat arranged on the side end face of the pool body and above the cleaning opening, a rotating rod rotatably arranged on the mounting seat, a connecting plate with an upper end fixedly arranged on the rotating rod and a lower end fixedly connected to the side end face of the plugging plate, and a fixing member arranged between the connecting plate and the pool body for fixedly connecting or removably fixing the connecting plate to the side end face of the pool body. The connecting plate is an L-shaped plate.

[0012] Further improvements are as follows: The fixing member includes a fixing seat arranged on the side end face of the pool body between the connecting plate and the side end face of the pool body, a corresponding jack formed in the connecting plate and corresponding to the fixing seat, and a fixing bolt threadedly connected to the fixing seat and located in the corresponding jack. The screw part of the fixing bolt is threadedly connected to the fixing seat, the screw part of the fixing bolt is located in the corresponding jack, and the head of the fixing bolt is located on one side of the connecting plate and away from the end face of the fixing seat.

[0013] Further improvements are as follows: A pulling handle is arranged on the side end face of the connecting plate.

[0014] Further improvements are as follows: An auxiliary inclined plane for facilitating the entry of the plugging plate into the cleaning opening is formed at the lower end of the side end face of the pool body at the cleaning opening.

[0015] After adopting the above technical solution, the beneficial effects of the present utility model are as follows: When it is necessary to clean the residue on the bottom surface of the pool body, first drain the precipitated sewage outwards through the drain pipe, and then fix the plugging plate in contact with the cleaning opening through the fixing device. Remove the plugging plate from the cleaning opening to open the cleaning opening. At this time, drive the moving plate to approach the cleaning opening end in the water storage cavity through the driving device, thereby driving the cleaning scraper to push the residue on the inner bottom surface of the pool body outwards through the cleaning opening. There is no need for manual entry into the pool to clean the residue. The cleaning method is simple and does not require excessive manual intervention, which can accelerate the cleaning speed of the residue at the bottom of the pool.

[0016] Further effect: When the cleaning scraper scrapes up the residue and moves towards the cleaning opening, the inclined surface can make the gradually scraped-up residue accumulate along the inclination angle of the inclined surface, improving the cleaning effect of the residue. Compared with directly setting a vertical scraper, it reduces the phenomenon that the scraped-up residue moves to both sides.

[0017] Further effect: When the rotating screw rotates, through the guide rod and the guide hole, the linkage plate will not rotate along with the rotating screw, and the linkage plate moves horizontally as the rotating screw rotates.

[0018] Further effect: When the plugging plate plugs the cleaning opening and it is necessary to fix the position of the plugging plate, squeeze the connecting plate so that its side end surface fits with the side end surface of the fixed seat. At this time, the corresponding jack is aligned with the threaded hole on the fixed seat. Insert the fixing bolt through the corresponding jack and thread it with the fixed seat. Rotate the fixing bolt so that its head gradually approaches one side of the connecting plate until the head of the fixing bolt abuts against one side of the connecting plate, thereby restricting the swing of the connecting plate on the rotating rod.

[0019] Further effect: When the plugging plate is pushed into the cleaning opening, the auxiliary inclined surface can make the sealing block of the plugging plate be squeezed by the auxiliary inclined surface and gradually generate elastic deformation, and as the plugging plate is pushed, it completely enters the cleaning opening.
