Description

Technical Field

[0001] The utility model relates to the technical field of silt removal devices, in particular to a silt removal device for a rainwater and sewage pump station. Background Art

[0002] The main function of a sewage pumping station is to raise the level of sewage so that it can be discharged smoothly out of the urban area. A sewage pumping station is usually composed of a water pump, a motor, a control system, a pipeline, etc., and the pumping and discharge of sewage is achieved through an automated control system.

[0003] A Chinese patent discloses a novel sewage pump station desilting device (publication number: CN214574555U). The patent comprises a tank body and an air pump. An aeration plate is provided at the bottom of the tank body. The air inlet end of the aeration plate is connected to the air pump pipeline. A support tube is provided at the top of the aeration plate, which is connected to the aeration plate. A stirring paddle is connected to the shaft on the outer wall of the support tube. The interior of the stirring paddle is a hollow structure, which is connected to the support tube. The outer wall of the stirring paddle is provided with an air outlet. The utility model utilizes the aeration plate to aerate the sludge at the bottom of the tank. At the same time, the aeration plate is modified to provide aeration holes in all directions of the aeration plate. This allows the sludge at the bottom of the tank to float, thereby achieving the purpose of clearing the sludge at the bottom of the tank. At the same time, utilizing the principle of gas injection, the stirring paddle added to the top of the aeration plate is connected to the air pipe of the aeration plate. The angled air outlet provided on the stirring paddle provides power to the stirring paddle, further achieving the effect of clearing the sludge at the bottom of the tank.

[0004] This patent uses the cooperation of air holes and stirring paddles to clean the sludge at the bottom of the tank. However, when cleaning the sludge, the stirring paddles and air holes cannot clean the sludge on both sides of the tank, resulting in the accumulation of sludge on both sides of the tank, resulting in poor cleaning effect. Utility Model Content

[0005] The technical problems to be solved by the present utility model are as follows:

[0006] When cleaning the sludge, the stirring paddles and air holes are unable to clean the sludge on both sides of the tank, resulting in the accumulation of sludge on both sides of the tank and poor cleaning effect.

[0007] The purpose of the utility model can be achieved through the following technical solutions:

[0008] A rainwater and sewage pump station silt clearing device includes a device body, one side of the device body is fixedly connected to a water pipe, the top of the device body is provided with a cleaning assembly, the cleaning assembly includes a connecting plate, one side of the connecting plate is fixedly connected to a fixing plate, one side of the fixing plate is installed with a first motor, the output end of the first motor is fixedly connected to a gear, the gear is rotatably connected to the fixing plate, one side of the connecting plate is fixedly connected to a connecting rod, one side of the connecting rod is fixedly connected to a limiting sleeve, the interior of the limiting sleeve is slidably connected to a rack, and the rack is slidably connected to the device body.

[0009] Furthermore, the bottom of the rack is rotatably connected to a scraper shell, and cleaning brushes are symmetrically fixed around the scraper shell, and the cleaning brushes abut against the inner wall of the device body.

[0010] Furthermore, a square plate is symmetrically fixed on the top of the device body, a block is symmetrically fixed on one side of the square plate, a second motor is installed on the top of the block, a threaded rod is rotatably connected between the blocks, and the output end of the second motor is fixedly connected to the threaded rod.

[0011] Furthermore, a threaded sleeve is sleeved on the outside of the threaded rod, one side of the threaded sleeve is fixedly connected to a square rod, one side of the square rod is fixedly connected to a telescopic rod, the telescopic rod is rotatably connected to the scraper shell, and a sliding groove is provided at the rotating shaft of the scraper shell and the telescopic rod.

[0012] Furthermore, a limiting rod is fixedly connected between the blocks, a sliding sleeve is slidably connected to the outside of the limiting rod, and the sliding sleeve is fixedly connected to the threaded sleeve.

[0013] Furthermore, slide plates are symmetrically slid on both sides of the device body, an auxiliary block is symmetrically fixed on one side of the slide plate, a bolt is threadedly connected to one side of the auxiliary block, and the bolt passes through the auxiliary block and is threadedly connected to the device body.

[0014] Furthermore, the cleaning brushes are arranged in a ring shape.

[0015] Beneficial effects of the utility model:

[0016] 1. By setting up a cleaning component, the first motor drives the gear to rotate, and then the gear drives the rack to move downward, and then the rack drives the scraper shell to move downward. Secondly, the downward movement of the scraper shell will drive the telescopic rod to stretch. When the scraper shell moves, it will drive the cleaning brush to move, so that the cleaning brush cleans the inner wall of the device body, and then the scraper shell will cover the silt at the bottom. Start the second motor on one side, so that the second motor drives the threaded rod to rotate, so that the telescopic rod will drive the scraper shell to scrape the silt inside the device body.

[0017] 2. When the scraper shell is finished scraping, the second motor on the other side can be started, so that the telescopic rod on the other side drives the scraper shell to scrape in the opposite direction, thereby scraping the sludge inside the device body to both sides of the inside of the device body. Then, the bolts on both sides can be removed and the slide plate can be pulled out to manually clean out the sludge inside the device body. This solves the problem that the stirring paddle and the air hole cannot clean the sludge on both sides of the tank during sludge cleaning, which causes the sludge to accumulate on both sides of the tank and the cleaning effect is poor.
