Description

Technical Field

[0002] Pump stations are indispensable infrastructure in urban drainage, rainwater and sewage lifting, water resource allocation and other systems. Traditional pump stations are usually made of on-site cast concrete, with a huge structure and a long construction period. A large amount of civil engineering work is required during the construction process. The construction process involves multiple processes such as on-site equipment installation, pipeline layout, and electronic control system integration. Construction is greatly affected by weather, topography, geology and other factors. Integrated prefabricated pump stations have a compact structure, easy maintenance, energy saving and environmental protection. Compared with traditional pump stations, integrated prefabricated pump stations have significant advantages. When existing integrated prefabricated pump stations are used for a long time, impurities will accumulate on the bottom and inner wall of the pump station, which will affect the efficiency of the pump station. When large impurities in sewage enter the sludge pump, it will cause the sludge pump to be blocked, which will reduce the sludge pump's transportation efficiency. Long-term wear and tear by large impurities will damage the sludge pump components, increasing maintenance costs. Summary of the Invention

[0014] Compared with the prior art, the present invention has the following beneficial effects:

When impurities are deposited or attached to the wall and bottom during the operation of the pump station, the attached materials can be effectively scraped off, which can prevent problems such as pipe blockage and increased pump load caused by long-term accumulation of impurities, thereby ensuring the transportation efficiency and operation stability of the pump station, thereby extending the service life of the equipment;

[0016] 2. The present invention adopts impurity separation technology to pre-treat the sewage entering the pumping station, separate large impurities, and prevent them from flowing into the subsequent sludge pump system with the medium. The separated large impurities are dehydrated to prevent transportation difficulties caused by high moisture content. At the same time, impurities attached to the wall of the separation cylinder can be scraped off to avoid long-term accumulation and blockage, which affects the separation efficiency. This improves the operational safety and reliability of the sludge pump and extends the service life of the equipment.

[0017] 3. The present invention adopts automatic water spraying technology. When the pump station is not used for a period of time, in order to prevent the impurities at the bottom from settling, agglomerating or adhering to cause blockage, water is sprayed inside the pump station at regular intervals. The water spraying process can effectively dilute the sludge, gravel and other solid impurities deposited at the bottom, so that they are suspended again, which is convenient for subsequent smooth pumping through the sludge pump, preventing the pump body from being overloaded or damaged due to excessive accumulation, reducing the frequency of manual cleaning, and ensuring that the pump station can be in good working condition for a long time.

[0044] Working principle of the present invention:

[0045] When sewage enters the separation drum 433 from the water inlet pipe 42, the second motor 41 is controlled to start, and the output shaft of the second motor 41 drives the second rotating shaft 46 to rotate, and the second rotating shaft 46 drives the fifth bevel gear 439 to rotate, and the fifth bevel gear 439 drives the fourth bevel gear 438 to rotate, and the fourth bevel gear 438 drives the screw rod 435 to rotate, and the screw rod 435 drives the separation drum 433 to rotate. Large impurities in the sewage will remain inside the separation drum 433, and the sewage will enter the cylinder body 31 after pre-filtration. Under the action of centrifugal force, the large impurities will stick to the wall of the separation drum 433 and rotate. When the large impurities rotate to the top of the feed trough, they fall into the collection pipe 436 under the action of gravity, and the large impurities are transported to the discharge pipe by the screw rod 435.

[0046] When the second motor 41 is started, the second rotating shaft 46 drives the fourth pinion 444 to rotate, the fourth pinion 444 drives the second belt 445 to rotate, the second belt 445 drives the third pinion 446 to rotate, the third pinion 446 drives the fourth rotating shaft to rotate, the fourth rotating shaft drives the second half gear 443 and the second pinion to rotate, the second pinion drives the first belt 447 to rotate, the first belt 447 drives the first pinion to rotate, the first pinion drives the first half gear 442 to rotate, when the first half gear 442 is engaged with the first rack, the second half gear 443 is disengaged from the second rack, the first half gear 442 drives the first gear 443 to rotate. The rack moves in the direction away from the bottom plate 431, the first rack drives the connecting plate 441 to move, and the connecting plate 441 drives the slider to slide in the track 434. When the first half gear 442 is disengaged from the first rack, the second half gear 443 is engaged with the second rack, and the second half gear 443 drives the second rack to move in the direction close to the bottom plate 431, the second rack drives the connecting plate 441 to move, and the connecting plate 441 drives the slider to slide in the track 434. The slider drives the brush to slide on the outer surface of the separation cylinder 433, and the brush will brush off the impurities attached to the inner wall of the separation cylinder 433, avoiding long-term accumulation of impurities and blockage, thereby extending the service life.

[0047] When large impurities enter the discharge pipe, the discharge pipe transports the large impurities to the discharge barrel 451 through the receiving pipe, and the second rotating shaft 46 drives the sixth bevel gear 452 to rotate, and the sixth bevel gear 452 drives the seventh bevel gear 453 to rotate, and the seventh bevel gear 453 drives the crankshaft 454 to rotate, and the crankshaft 454 drives the rocker 455 to rotate, and the rocker 455 drives the punch head 456 to slide up and down on the inner wall of the discharge barrel 451, pressing the large impurities in the discharge barrel 451 onto the filter plate 458, and filtering the water in the large impurities into the cylinder body 31. When the large impurities in the discharge barrel 451 accumulate to a certain volume, the punch head 456 squeezes the large impurities, and the second one-way valve prevents the large impurities from flowing back into the receiving pipe. When the pressure exceeds the elastic force of the pre-tightening spring of the first one-way valve, the first one-way valve opens, and the large impurities are discharged from the discharge pipe 457.

[0048] When a predetermined time interval passes, the control system controls the first motor 343 to start, the output shaft of the first motor 343 drives the support frame to rotate, the support frame drives the sun gear 342 to rotate, the sun gear 342 drives the planetary gears to rotate, and at the same time the planetary gears revolve around the sun gear 342, the planetary gears drive the first rotating shaft 344 to rotate, the first rotating shaft 344 drives the scraper to rotate, the scraper scrapes off the impurities attached to the inner wall of the cylinder 31, the sun gear 342 drives the first bevel gear 347 to rotate, the first bevel gear 347 drives the second bevel gear 348 to rotate, the second bevel gear 348 drives the third bevel gear to rotate, the third bevel gear drives the rotating disk 3491 to rotate, the rotating disk 3491 drives the slide rail 3492 to rotate, at this time the slide rail 3492 and the sun gear 342 Rotating in the opposite direction, the slide rail 3492 drives the protruding rod 3493 to rotate around the cam 346, and the protruding rod 3493 slides on the cam 346. When the protruding rod 3493 slides to the flange of the cam 346, the cam 346 pushes the protruding rod 3493 to slide in the slide rail 3492, and the protruding rod 3493 slides in the direction close to the inner wall of the cylinder 31, and the protruding rod 3493 drives the scraping head 3494 to slide. When the protruding rod 3493 slides to the base circle of the cam 346, the spring tension drives the protruding rod 3493 to slide in the slide rail 3492, and the protruding rod 3493 slides in the direction away from the inner wall of the cylinder 31, and the protruding rod 3493 drives the scraping head 3494 to slide. When the protruding rod 3493 rotates to the first rotating shaft 344, the protruding rod 3493 is just in contact with the base circle of the cam 346.

[0049] When sewage enters the cylinder 31, the sludge pump 52 is controlled to start. The sludge pump 52 pumps the sewage in the cylinder 31 into the sewage pipe 53, and the sewage enters the diversion box 54. Part of the sewage enters the outlet pipe 55 for discharge, and the other part of the sewage enters the water storage tank 56 through the return pipe, and the sewage is filtered by the filter plate. The filtered water is stored in the water storage tank 56. When a certain amount of water is stored, the float valve blocks the return pipe. When the pump station is not used for a period of time, the drain valve is controlled to start, and water is sprayed into the cylinder 31 from the water pipe to dilute the sludge, gravel and other solid impurities deposited at the bottom, so that they are suspended again, which is convenient for the sludge pump 52 to pump and discharge smoothly.
