Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a booster pump tank with sediment removal capabilities. Background Technology

[0002] Currently, wastewater treatment plants strive to minimize the number of times wastewater is lifted, often employing gravity flow where elevation permits. However, most plants are constrained by influent elevation and require underground lift pump tanks upstream of the main treatment process to collect the incoming water before pumping it into subsequent processes. This satisfies the elevation requirements of these processes and ensures continuous influent flow. However, due to the high suspended solids content in most wastewater treatment plants and the lack of effective sludge removal measures in the lift pump tanks, despite agitation, some large particles inevitably settle at the bottom of the tank while lighter suspended solids float on top. Over time, the accumulated sludge and large particles reduce the usable volume of the lift pump tank, and the level gauge readings become inaccurate, ultimately affecting the wastewater lifting efficiency and impacting the entire process. To ensure operational efficiency, the lift pump tanks are periodically shut down for maintenance and manual cleaning, which is time-consuming, labor-intensive, and poses safety hazards. Utility Model Content

[0023] like Figure 1 As shown, a preferred embodiment of the present invention provides a booster pump tank with sediment removal capability, including a frame 1, a tank body 2 mounted on the frame 1, a stirring mechanism, a sludge crushing mechanism, a sludge discharge mechanism, and a sludge scraping mechanism mounted on the tank body 2.

[0024] The pool body 2 is equipped with an inlet pipe 21 and an outlet pipe 22. A conical hopper 23 is located at the bottom of the pool body 2. One end of the outlet pipe 22 is connected to the outlet of the pool body 2, which is located at the top of the conical hopper 23. Wastewater to be treated enters the pool body 2 through the inlet pipe 21 and is discharged through the outlet pipe 22 after being processed by the sludge removal and scraping mechanisms. The other end of the outlet pipe 22 is connected to a water pump 8 located outside the pool body 2 to pump out the treated wastewater from the pool body 2. Since the primary purpose of the booster pump pool is not to remove suspended solids, but only to collect and remove large, easily settling particles, the angle of inclination of the conical hopper 23 at the bottom of the pool body 2 does not need to be too large to avoid wasting the usable volume of the pool body 2.

[0025] The mixing mechanism includes a lifting device 31 and a submersible mixer 32. When the pump tank is running, the submersible mixer 32 is in a normally open state. By mixing, it reduces the settling of suspended solids in the tank 2, achieves uniform water quality, and stabilizes the water supply for subsequent processes. When the tank 2 is under maintenance, the submersible mixer 32 can be lifted to the ground by the lifting device 31 for inspection and maintenance. The lifting device 31 may include a gear and a toothed belt sleeved on the gear. The toothed belt is connected to the submersible mixer 32, and the gear is connected to a motor. The motor drives the gear and toothed belt to rotate, thereby driving the submersible mixer 32 to rise and fall, thereby adjusting the position of the submersible mixer 32 in the tank 2.

[0026] The sludge discharge mechanism is located at the conical hopper 23 and includes a sludge discharge pipe 51 and a sludge discharge pump 52. One end of the sludge discharge pipe 51 is connected to the bottom of the conical hopper 23, and the other end is connected to the sludge discharge pump 52. The other end of the sludge discharge pipe 51 is equipped with a sludge discharge valve 53. By opening the sludge discharge valve 53, the sludge discharge pump 52 can easily discharge the sludge and wastewater deposited in the conical hopper 23. The sludge discharge pump 52 facilitates the collection and timely discharge of large particles that are heavier, ensuring the usable volume of the booster pump tank. Figure 2 As shown, the sludge pump 52 is provided with a pump inlet 521 and a pump outlet 522. The pump inlet 521 is connected to the other end of the sludge discharge pipe 51. When the sludge pump 52 is started, the pump inlet 521 of the sludge pump 52 will generate suction to continuously draw the sludge and sewage in the cone hopper 23 into the sludge pump 52 and discharge it from the pump outlet 522 of the sludge pump 52.

[0027] like Figure 3 , Figure 4 As shown, a screen 65 and a screen clearing mechanism are provided on the inner side of one end of the sludge discharge pipe 51. The screen clearing mechanism includes multiple fixed spokes 61, an impeller 62, a rotating shaft 63, and a scraper 64 disposed on the inner side of the sludge discharge pipe 51. The fixed spokes 61 and the screen 65 are fixedly connected to the inner wall of the sludge discharge pipe 51, and the fixed spokes 61 and the screen 65 are spaced apart. The screen 65 is used to intercept large particles in the sludge to prevent large particles from entering the sludge discharge pump 52 and causing blockage inside the pump inlet 521. One end of the multiple fixed spokes 61 is connected to the inner wall of the sludge discharge pipe 51, and the other end intersects. The rotating shaft 63 is rotatably connected to the position where the multiple fixed spokes 61 intersect. One end of the rotating shaft 63 is connected to a scraper 64, which is attached to the screen 65. The other end of the rotating shaft 63, away from the screen 65, is fixedly connected to an impeller 62. When the sludge pump 52 works to pump the sludge and sewage in the cone hopper 23 into the sludge pump 52, the impeller 62 inside the sludge discharge pipe 51 is rotated by the impact of the water flow and sludge. The rotation of the impeller 62 drives the rotating shaft 63 and the scraper 64 to rotate. Thus, the rotation of the scraper 64 scrapes off the large particles intercepted by the screen 65, preventing the large particles from accumulating on one side of the screen 65 and causing blockage inside the screen 65 and the sludge discharge pipe 51, thereby improving the sludge discharge efficiency of the sludge pump 52.

[0028] The sludge crushing mechanism is located in the cone hopper 23 and includes a rotating shaft 41, multiple crushing blades 42 disposed on the outer periphery of the rotating shaft 41, and a drive motor 43 connected to the rotating shaft 41. The drive motor 43 is installed at the bottom of the cone hopper 23, and the rotating shaft 41 and the crushing blades 42 are located inside the cone hopper 23. The drive motor 43 drives the rotating shaft 41 to rotate, which in turn drives the crushing blades 42 to rotate. Large particles in the sludge settle into the cone hopper 23 and are quickly crushed by the rotating multiple crushing blades 42, effectively reducing the entry of large particles in the sludge into the sludge discharge pump 52 and causing blockage inside the pump inlet 521. In addition, by quickly crushing large particles in the sludge through the sludge crushing mechanism, large particles are prevented from being discharged by the sludge discharge pump 52 and deposited at the bottom of the cone hopper 23, realizing non-manual sludge discharge during continuous operation and saving manpower.

[0029] The sludge scraping mechanism is located at the upper part of the pool body 2 and is used to promptly scrape off the floating sludge in the pool body 2 to avoid affecting the level gauge data due to excessive floating sludge and causing fluctuations in the water quality of subsequent incoming water due to floating sludge being sucked up by the water pump 8. The sludge scraping mechanism includes a sprocket 71, a chain 72, and multiple scraper blades 73. A floating sludge collection trough 74 is provided on one side inside the pool body 2, and the floating sludge collection trough 74 is close to the sludge scraping mechanism. The chain 72 is sleeved on the sprocket 71, and the multiple scraper blades 73 are fixed on the chain 72. The sprocket 71 is connected to a motor, which drives the sprocket 71 to rotate, causing the chain 72 and the scraper blades 73 to rotate around the sprocket 71, so that the scraper blades 73 scrape the floating sludge in the pool body 2 to the floating sludge collection trough 74.

[0030] Preferably, the sludge discharge pipe 51 is provided with a sludge discharge branch pipe 55, which extends upward and communicates with the floating sludge collection tank 74, so that the sludge discharge pump 52 can discharge the floating sludge collected in the floating sludge collection tank 74 through the sludge discharge branch pipe 55.

[0031] Preferably, the screen 65 and screen unblocking mechanism can also be provided inside the sludge discharge branch pipe 55 to prevent the sludge discharge pump 52 and the screen 65 from becoming clogged, thereby ensuring the sludge discharge efficiency of the sludge discharge pump 52.

[0032] The aforementioned booster pump pool, through the agitation mechanism, sludge crushing mechanism, sludge discharge mechanism, and sludge scraping mechanism installed in the pool body 2, enables the booster pump pool to have a certain ability to clean and remove sludge when treating sewage with high suspended solids, reducing the need for manual labor. When floating sludge appears on the surface of the pool body 2, it can be cleaned by the sludge scraping mechanism installed on the upper part of the pool body 2, which saves manpower and ensures the visibility of the water surface in the booster pump pool, ensuring the accuracy of the level gauge. When the usable volume of the booster pump pool gradually decreases due to the accumulation of large particles, the sludge crushing mechanism can be used to quickly crush the large particles in the sludge to prevent them from settling at the bottom of the cone hopper 23. Then, the sludge discharge mechanism can be used to discharge the sediment from the pool body 2 in a timely manner, which not only ensures the usable volume of the booster pump pool, but also avoids the blockage of the sludge discharge pump 52 due to a large amount of large particles entering the sludge discharge pump 52. This achieves non-manual sludge discharge during continuous operation of the booster pump pool, saving manpower.
