Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically to a modular wastewater treatment station. Background Technology

[0002] Modular wastewater treatment plants break down the wastewater treatment process into multiple independent functional modules, which are prefabricated in the factory and then transported to the site for assembly. These modules include: a pretreatment module to remove large suspended solids and floating matter and balance water quality and quantity; a biological treatment module to decompose organic pollutants through microbial metabolism; an advanced treatment module to further remove residual pollutants; a disinfection module to kill harmful bacteria; and a sludge treatment module responsible for sludge thickening and dewatering.

[0003] After prolonged use, sludge sedimentation tanks in traditional modular wastewater treatment plants accumulate sludge at the bottom. This is typically treated with a sludge scraper, but the scraper moves in a reciprocating straight line or circular motion along the bottom of the tank, only removing the bottom sludge. There are blind spots on the tank walls, allowing sludge to accumulate easily. As the sludge thickens, pollutants are released, leading to a deterioration in the effluent quality, affecting subsequent treatment, and making it difficult for the water to meet discharge or reuse standards. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a modular sewage treatment plant to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a modular sewage treatment station, including a sewage treatment station body and a sedimentation tank disposed inside the sewage treatment station body, wherein a sludge scraping assembly is installed on the top of the sewage treatment station body above the sedimentation tank;

[0006] The sludge scraping assembly includes a side plate fixedly connected to the surface of the main body of the sewage treatment plant. A motor is fixedly installed on the top of the side plate. A threaded rod is fixedly connected to the output end of the motor. A sliding column is threadedly connected to the outer surface of the threaded rod. A connecting column is fixedly connected to the center of the bottom of the threaded rod. A fixing frame is fixedly connected to the end face of the connecting column away from the threaded rod. A scraper is fixedly installed on the side of the fixing frame by bolts. A drive assembly is installed at the end of the sliding column away from the side plate.

[0007] Furthermore, the drive assembly includes a fixed box fixedly connected to the surface of the main body of the sewage treatment plant. The fixed box has a sliding groove inside, a sliding rod fixedly connected inside the sliding groove, a connecting rod fixedly connected to the surface of the sliding rod, a connecting pipe fixedly connected inside the connecting rod, a rubber sealing plate fixedly connected to the end face of the connecting rod, a first DC one-way valve fixedly installed at the input end of the connecting pipe, an air outlet groove and a water storage groove inside the fixed box, a second DC one-way valve fixedly installed inside the fixed box, a water inlet pipe fixedly connected to the input end of the second DC one-way valve, and nozzles equidistantly installed inside the connecting column.

[0008] Furthermore, the outer surface of the slide bar is inserted into the interior of the sliding column, and the sliding column is slidably connected to the interior of the slide groove via the slide bar.

[0009] Furthermore, the interior of the water storage tank is connected to the input end of the nozzles via a first DC one-way valve, a connecting pipe, and the nozzles themselves. There are four nozzles and four scrapers, and the scrapers are triangular in shape.

[0010] Furthermore, the end of the water inlet pipe away from the second DC one-way valve is placed in the water tank.

[0011] Furthermore, the inner top of the water storage tank is connected to the outside of the fixed box through an air outlet, and the outer surface of the rubber sealing plate is slidably connected to the inside of the water storage tank.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model, by setting up a sludge scraping component, can automatically scrape and clean the sludge around the inside of the sedimentation tank. When the fixed frame slides up and down, it can suck in the liquid inside the water storage tank and spray the liquid sucked in from the water storage tank through the nozzle to rinse the inner wall of the sedimentation tank. This makes up for the defect of traditional sludge scraper machines that cannot clean the tank wall, can remove the accumulated sludge in time, prevent the sludge from hardening due to long-term adhesion, reduce the difficulty of sludge cleaning, maintain good sedimentation and separation effect of the sedimentation tank, and ensure the smooth flow of sewage treatment process.

[0014] 2. By setting the fixing frame outside the sedimentation tank, this utility model can prevent sludge from adhering to the surface of the fixing frame or scraper when the sewage inside the sedimentation tank is settling, thus avoiding the situation where the water quality is polluted again. This helps to ensure the quality of sewage treatment, making the effluent water quality more stable and easier to meet the discharge standards or reuse standards. Attached Figure Description

[0020] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0021] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0022] Specifically, a modular sewage treatment plant includes a sewage treatment plant body 1 and a sedimentation tank 2 set inside the sewage treatment plant body 1. A sludge scraping assembly 3 is installed on the top of the sewage treatment plant body 1 above the sedimentation tank 2.

[0023] The sludge scraping assembly 3 includes a side plate 31 fixedly connected to the surface of the main body 1 of the sewage treatment plant. A motor 32 is fixedly installed on the top of the side plate 31. A threaded rod 34 is fixedly connected to the output end of the motor 32. A sliding column 33 is threadedly connected to the outer surface of the threaded rod 34. A connecting column 35 is fixedly connected to the center of the bottom of the threaded rod 34. A fixing frame 36 is fixedly connected to the end face of the connecting column 35 away from the threaded rod 34. A scraper 37 is fixedly installed on the side of the fixing frame 36 by bolts. A drive assembly 38 is installed at the end of the sliding column 33 away from the side plate 31. The drive assembly 38 includes a fixing box 381 fixedly connected to the surface of the main body 1 of the sewage treatment plant. The interior of the fixing box 381... A sliding groove 382 is provided, and a sliding rod 383 is fixedly connected inside the sliding groove 382. A connecting rod 384 is fixedly connected to the surface of the sliding rod 383. A connecting pipe 385 is fixedly connected inside the connecting rod 384. A rubber sealing plate 387 is fixedly connected to the end face of the connecting rod 384. A first DC one-way valve 388 is fixedly installed at the input end of the connecting pipe 385. An air outlet groove 386 and a water storage groove 389 are provided inside the fixed box 381. A second DC one-way valve 3810 is fixedly installed inside the fixed box 381. A water inlet pipe 3811 is fixedly connected to the input end of the second DC one-way valve 3810. Spray nozzles 4 are installed at equal intervals inside the connecting column 35.

[0024] In this implementation scheme, by setting up the sludge scraping component 3, the sludge can be automatically scraped and cleaned around the inside of the sedimentation tank 2. When the fixed frame 36 slides up and down, it can suck up the liquid inside the water storage tank 389 and spray the liquid sucked in from the water storage tank 389 through the nozzle 4 to rinse the inner wall of the sedimentation tank 2. This makes up for the defect of traditional sludge scraper machines that cannot clean the tank wall, can remove the accumulated sludge in time, prevent the sludge from hardening due to long-term adhesion, reduce the difficulty of sludge removal, maintain the good sedimentation and separation effect of the sedimentation tank 2, and ensure the smooth flow of sewage treatment process.

[0025] Specifically, the outer surface of the slider 383 is inserted into the interior of the sliding post 33, and the sliding post 33 is slidably connected to the interior of the groove 382 through the slider 383.

[0026] In this embodiment, by setting the slider 383, the stability of the sliding column 33 can be improved.

[0027] Specifically, the interior of the water storage tank 389 is connected to the input end of the nozzle 4 via the first DC one-way valve 388, the connecting pipe 385, and the nozzle 4. There are four nozzles 4 and four scrapers 37, which are triangular in shape.

[0028] In this embodiment, four nozzles 4 are installed to rinse the inner wall of the sedimentation tank 2.

[0029] Specifically, the end of the inlet pipe 3811 that is away from the second DC one-way valve 3810 is placed in the water tank.

[0030] In this embodiment, by setting a second DC one-way valve 3810, the liquid inside the water storage tank 389 can be prevented from flowing back through the water inlet pipe 3811.

[0031] Specifically, the top of the interior of the water storage tank 389 is connected to the exterior of the fixed box 381 through the air outlet 386, and the outer surface of the rubber sealing plate 387 is slidably connected to the interior of the water storage tank 389.

[0032] In this embodiment, the air pressure inside the water storage tank 389 can be controlled by setting a rubber sealing plate 387.

[0033] The working principle and usage process of this utility model are as follows: During use, the starting motor 32 drives the threaded rod 34 to rotate. Through the engagement of the threaded rod 34 with the sliding column 33, the sliding column 33 slides. The sliding column 33, via the connecting column 35, drives the fixed frame 36 and scraper 37 to slide inside the sedimentation tank 2. This up-and-down sliding motion cleans the sludge around the inner wall of the sedimentation tank 2. When the sliding column 33 slides downwards, it drives the rubber sealing plate 387 downwards via the connecting rod 384. At this time, the water storage tank 389 is under high pressure, and the second DC one-way valve 3810 is in a sealed state. Water inside the water storage tank 389 flows through the first DC one-way valve 388 and the connecting pipe 38... 5. Spraying from nozzle 4, it can clean the inner wall of sedimentation tank 2. When the sliding column 33 drives the connecting rod 384 and the rubber sealing plate 387 to slide upward, the water storage tank 389 is under negative pressure. The first DC one-way valve 388 is closed, and the water in the water tank can enter the water storage tank 389 through the inlet pipe 3811 and the second DC one-way valve 3810 to store water in the water storage tank 389. This cycle continues. This cleaning method makes up for the shortcomings of traditional sludge scraper machines that cannot clean the tank wall. It can remove the accumulated sludge in time, prevent the sludge from hardening due to long-term adhesion, reduce the difficulty of sludge removal, maintain the good sedimentation and separation effect of sedimentation tank 2, and ensure the smooth flow of sewage treatment process.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
