Description

Technical Field

[0001] This utility model relates to the field of sludge degradation and sedimentation technology, specifically a vertical flow sludge degradation and sedimentation tank. Background Technology

[0002] Vertical flow sludge degradation sedimentation tank is a special sedimentation tank design, mainly used for the degradation and sedimentation of sludge in the sewage treatment process.

[0003] Chinese utility model patent CN221971415U discloses a reaction tank for wastewater treatment engineering, relating to the field of wastewater treatment engineering technology. The reaction tank includes an inlet tank and a reaction tank body. The inlet tank is located on one side of the reaction tank body and has a sieve plate inside. A scraper plate inside the reaction tank body agitates the sludge and impurities at the bottom of the reaction tank body, preventing them from settling and adhering to the bottom for extended periods. Simultaneously, the scraper plate ensures sufficient contact between the sludge containing microorganisms and the wastewater, improving the biodegradation efficiency of the reaction tank. The sieve plate inside the inlet tank provides preliminary treatment of the wastewater, removing impurities that are difficult to biodegrade. An inclined plate inside the sedimentation tank causes the sludge to encounter resistance and settle, allowing for thorough sedimentation and separation of the sludge and microorganisms, preventing the loss of microorganisms from the sludge.

[0004] However, although the above-mentioned device can degrade and settle wastewater, it does not have the function of cleaning the screen plate. If a lot of impurities accumulate on the top of the screen plate, it will affect the screening efficiency of the screen plate, thereby affecting the use of the entire device and making it inconvenient for users to use.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 This utility model discloses a vertical flow sludge degradation sedimentation tank, including a reaction tank 1, an inlet tank 3, and a sedimentation tank 5. An inlet box 101 is fixedly installed at the bottom of the reaction tank 1, and an outlet trough 102 is fixedly installed on one side of the reaction tank 1. An inlet 301 is fixedly installed at the top of the inlet tank 3. A sieve plate 302 is movably installed inside the inlet tank 3. A threaded rod 305 is movably installed inside the inlet tank 3 and above the sieve plate 302. One end of the threaded rod 305 passes through one side of the inlet tank 3 and extends to the outside of the inlet tank 3. A rotating handle 306 is fixedly installed at one end of the threaded rod 305. A nut seat 307 is movably installed outside the threaded rod 305. A cleaning brush 308 is fixedly installed at the bottom of the nut seat 307. A sealing plate 309 is bolted to one side of the inlet tank 3.

[0020] Specifically, a motor 2 is fixedly installed on the top of the reaction tank 1. The output shaft of the motor 2 passes through the top of the reaction tank 1 and extends into the interior of the reaction tank 1. The output shaft of the motor 2 is fixedly connected to the top of the connecting plate 201. A scraper 202 is fixedly installed on the bottom of the connecting plate 201.

[0021] In this embodiment, by setting up a motor 2, a connecting plate 201 and a scraper 202, starting the motor 2 causes its output shaft to drive the connecting plate 201 to rotate, which in turn causes the connecting plate 201 to drive the scraper 202 to rotate, so that the degradation liquid and sewage are mixed more thoroughly. The scraper 202 can scrape off the sludge on the inner wall of the reaction tank 1, improving the cleaning efficiency of the reaction tank 1. It has strong practicality and is easy for users to use.

[0022] Specifically, sliders 303 are fixedly installed on both sides of the sieve plate 302, and grooves 304 adapted to sliders 303 are opened on both sides of the inner wall of the water inlet tank 3. The connection between sliders 303 and grooves 304 is a sliding connection.

[0023] In this embodiment, by setting up a slider 303 and a chute 304, and utilizing the sliding connection between the slider 303 and the chute 304, when it is necessary to disassemble the sieve plate 302, the sieve plate 302 can be pulled out from the inside of the water inlet tank 3 by pulling the sieve plate 302, which facilitates the maintenance of the sieve plate 302, ensures the screening efficiency of the sieve plate 302, has strong practicality, and is easy for users to use.

[0024] Specifically, the connection between the threaded rod 305 and the nut seat 307 is a threaded connection, and the nut seat 307 has a threaded hole inside that is compatible with the threaded rod 305.

[0025] In this embodiment, by setting a threaded rod 305 and a nut seat 307, and utilizing the threaded connection between the threaded rod 305 and the nut seat 307, the threaded rod 305 is rotated by rotating the rotating handle 306, which causes the nut seat 307 to drive the cleaning brush 308 to move horizontally, thereby cleaning the screen plate 302.

[0026] Specifically, a first pipe 4 is fixedly installed at the bottom of the water inlet tank 3, a first water pump 401 is installed on the outside of the first pipe 4, and the other end of the first pipe 4 passes through the water inlet box 101 and extends into the interior of the reaction tank 1.

[0027] In this embodiment, by setting up a first pipeline 4 and a first water pump 401, the first water pump 401 is started to draw the sewage from the water inlet tank 3 and transport it through the first pipeline 4 to the inside of the reaction tank 1, so that it can be mixed with the degradation liquid inside the reaction tank 1, and the sewage can be degraded.

[0028] Specifically, an inclined plate 501 is fixedly installed inside the sedimentation tank 5, a drain pipe 502 is fixedly installed on one side of the sedimentation tank 5, the other end of the drain pipe 502 is fixedly connected to one side of the water inlet box 101, a second pipe 503 is fixedly installed on the top of the sedimentation tank 5, the other end of the second pipe 503 is fixedly connected to the top of the reaction tank 1, and a second water pump 504 is installed outside the second pipe 503.

[0029] In this embodiment, by setting up a sedimentation tank 5, a sewage discharge pipe 502, a second pipe 503 and a second water pump 504, the sewage after reaction in the reaction tank 1 enters the sedimentation tank 5 for sedimentation. Then, by starting the second water pump 504, the undegraded sewage in the sedimentation tank 5 is transported to the interior of the reaction tank 1 through the second pipe 503 for re-degradation, thereby improving the sewage degradation efficiency.

[0030] In use, the user first pours the wastewater into the inlet tank 3. After the impurities are filtered by the sieve plate 302, the first water pump 401 is started to draw the wastewater from the inlet tank 3 and transport it through the first pipe 4 to the inside of the reaction tank 1, where it mixes with the degradation liquid inside the reaction tank 1. The motor 2 is started to make its output shaft drive the connecting plate 201 to rotate, which in turn drives the scraper 202 to rotate, making the degradation liquid and wastewater mix more thoroughly. The scraper 202 can scrape off the sludge on the inner wall of the reaction tank 1, improving the cleaning efficiency of the reaction tank 1. After the wastewater reacts in the reaction tank 1, it enters the sedimentation tank 5 for sedimentation. Then, the second water pump 504 is started to transport the undegraded wastewater in the sedimentation tank 5 through the second pipe 503 to the inside of the reaction tank 1 for re-degradation, improving the wastewater degradation efficiency.

[0031] In summary, this vertical flow sludge degradation sedimentation tank, by incorporating cleaning brushes 308, allows for easy cleaning of impurities on the top of the screen plate 302. Users first remove the sealing plate 309 by rotating the bolts, then rotate the rotating handle 306 to rotate the threaded rod 305. This causes the nut seat 307 to move horizontally along the outside of the threaded rod 305, which in turn causes the cleaning brushes 308 to move horizontally, thus removing impurities from the top of the screen plate 302 from the discharge outlet. This improves the convenience of impurity cleaning, making it highly practical and user-friendly.
