Description

Technical Field

[0001] The present application relates to the technical field of sewage treatment, and specifically to a sewage sedimentation tank. Background Art

[0002] Sewage refers to the discharged water from life and production that is polluted to a certain extent. Water that has lost its original use function is simply called sewage. Sewage is caused by the addition of new substances into the water or due to changes in external conditions, which causes the water to deteriorate and can no longer maintain its original use function. Sewage usually comes from domestic wastewater, industrial wastewater, and agricultural wastewater. In order to improve the utilization rate of water resources, it is usually necessary to purify sewage. In the process of sewage treatment, sewage sedimentation treatment is an indispensable part. Sewage sedimentation treatment can effectively remove suspended matter, plankton, organic particles and some dissolved pollutants in sewage. Through sedimentation, these pollutants can settle to the bottom to form sludge, thereby purifying the water quality.

[0003] For example, the patent with authorization announcement number CN213171609U discloses a sewage sedimentation tank, including a main tank body, an infrared transmitting device, an infrared receiving device, a small centrifugal water pump and an installed buoyancy platform. The threaded assembly method is used so that the buoyancy platform can automatically adjust the height according to the internal water body, making the extraction method more diverse.

[0004] Although the above-mentioned device realizes the treatment of sewage, since sewage does not only come from life and industry, when the rainy season comes, the erosion of rainwater will also bring a large amount of pollutants such as mud and stone particles to mix with rainwater to form sewage, so that some sewage will contain more particulate matter. When the sewage sedimentation tank settles the sewage, the mixture of silt and stone particles will settle at the bottom of the treatment tank. However, when the sedimentation tank discharges the sewage, the pollutants are often only sucked out of the sedimentation tank through a sewage pipe and a suction pump. However, due to the limited diameter of the sewage pipe, when a large amount of mud and stone particles enter the sewage pipe, it is easy to cause blockage in the sewage pipe, thereby affecting the subsequent sewage treatment. Therefore, it is necessary to provide a sewage sedimentation tank to solve the above problems.

[0005] It should be noted that the above information disclosed in this Background section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute prior art. Summary of the Invention

[0006] Based on the above problems existing in the prior art, the problem to be solved by this application is: to provide a sewage sedimentation tank, which solves the problem that the sewage sedimentation tank cannot screen the mixture of mud and stone particles, resulting in blockage of the sewage pipe.

[0007] The technical solution adopted by the present application to solve its technical problems is: a sewage sedimentation tank, including a tank body, a drain outlet is provided on one side of the tank body; an auxiliary flow device, which is installed in the tank body, the auxiliary flow device includes a guide tube with a bearing installed at the center of the bottom of the tank body, and a driving device is fixedly installed on the top of the guide tube; a horn groove, which is arranged at the bottom of the tank body, and a sewage outlet is provided on one side of the horn groove; a fixed sleeve, the fixed sleeve bearing is installed on the surface of the guide tube, and a return spring is fixedly installed on the bottom of the fixed sleeve; a sliding sleeve, the sliding sleeve is fixedly installed on the bottom of the return spring, the surface bearing of the guide tube is installed with a sleeve, and the sliding sleeve is slidably installed on the surface of the sleeve; a filter plate, which is fixedly installed on the outer ring of the sliding sleeve, the outer ring of the filter plate is fixedly connected to the top of the inner wall of the horn groove, and at least two groups of filter holes are provided on the surface of the filter plate.

[0008] Furthermore, the horn groove is provided with an opening, which gradually narrows in a direction away from the upper end of the guide tube, and the bottom of the pool body is inclined downward in a direction away from the inner wall of the pool body.

[0009] Furthermore, the filter plate is made of rubber.

[0010] Furthermore, a support platform is fixedly installed on the top of the inner wall of the pool body, the driving device is fixedly connected to the driving device, and a lower auxiliary flow rod is fixedly installed on the surface of the bottom of the guide tube, and the side of the lower auxiliary flow rod away from the guide tube is in contact with the inside of the bottom of the pool body.

[0022] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0024] like Figure 1-Figure 2 As shown, the present application provides a sewage sedimentation tank, including a tank body 1, which is the sewage sedimentation tank body. The interior of the tank body 1 is hollow and provided with a sewage inlet to facilitate the entry and storage of sewage. Under normal circumstances, when sewage enters the tank body 1, due to gravity, impurities in the sewage will freely settle at the bottom of the tank body 1. This process is called initial sedimentation, and the initial evolution of the sewage is achieved without any operation.

[0025] An auxiliary flow device 2 is installed inside the tank body 1. The auxiliary flow device 2 is mainly used to assist sewage sedimentation and facilitate the separation of impurities in the sewage. The auxiliary flow device 2 includes a guide tube 21 with a bearing installed at the center of the bottom of the tank body 1. The guide tube 21 can be understood as a pipe. Through the guide tube 21, liquid for sewage sedimentation can be easily injected from the bottom into the tank body 1;

[0026] A support platform 24 is fixedly installed on the top of the inner wall of the pool body 1. A driving device 22 is fixedly installed at the center of the support platform 24. The output end of the driving device 22 passes through the support platform 24 and is fixedly connected to the top of the guide tube 21. In this application, the driving device 22 is an electric motor or a drive motor. When the driving device 22 is started, it can drive the guide tube 21 to rotate.

[0027] It should be noted that, in order not to affect the injection of liquid into the pool body 1 by the guide tube 21, the upper end of the guide tube 21 can be set as a solid part, and the driving device 22 is connected to the solid part, and a plurality of through holes are opened on the surface of the guide tube 21 near the solid part, so that the liquid injected by the guide tube 21 is discharged from the through holes;

[0028] Continue to refer Figure 2 A lower auxiliary flow rod 23 is fixedly mounted on the surface of the bottom of the guide cylinder 21. The side of the lower auxiliary flow rod 23 away from the guide cylinder 21 contacts the inner wall of the bottom of the pool body 1. When the guide cylinder 21 rotates under the drive of the driving device 22, the lower auxiliary flow rod 23 rotates synchronously, mainly used to stir the pollutants deposited at the bottom of the pool body 1, so as to facilitate the cleaning of the pollutants attached to the bottom of the pool body 1;

[0029] After the sewage has settled for a period of time, the heavy pollutants will fall to the bottom of the tank body 1, while the lighter pollutants will float on the sewage. Figure 2 As shown, an upper auxiliary flow rod 26 is fixedly mounted above the surface of the guide cylinder 21. The upper auxiliary flow rod 26 rotates synchronously when the driving device 22 is started to sweep away the lighter pollutants on the sewage in the tank body 1. A slag collecting hopper 27 is also fixedly mounted in the tank body 1 to collect the swept pollutants.

[0030] A clean water channel 25 is fixedly installed at the bottom of the support platform 24 near the inner wall of the tank body 1. The clean water channel 25 is located at a higher position in the inner cavity of the tank body 1 and is mainly used to collect sewage with less pollutants after sedimentation.

[0031] A drain outlet 5 is provided on one side of the tank body 1. The height of the drain outlet 5 is consistent with the high position of the clean water channel 25. When too much water accumulates in the clean water channel 25, the settled sewage will overflow the clean water channel 25 and be discharged from the drain outlet 5, thereby facilitating the collection of the settled sewage.

[0032] like Figure 2-Figure 3 As shown, a trumpet groove 7 is provided at the bottom of the tank body 1. The trumpet groove 7 is provided with an opening, which gradually narrows in a direction away from the upper end of the guide cylinder 21, and the bottom of the tank body 1 is inclined, and its inclination direction is downward in a direction away from the inner wall of the tank body 1. Therefore, the pollutants settled at the bottom of the tank body 1 will continuously slide into the trumpet groove 7 due to the inclination of the bottom of the tank body 1 and accumulate in the trumpet groove 7. The trumpet groove 7 can be understood as a collection part in the tank body 1 for collecting pollutants with a larger weight after precipitation;

[0033] A sewage outlet 8 is provided on one side of the horn groove 7, and the other side of the sewage outlet 8 extends to the outside of the tank body 1. At the same time, a sewage pipe 3 is fixedly installed on the other side of the sewage outlet 8. The pollutants accumulated in the horn groove 7 can be discharged from the sewage pipe 3 through the sewage outlet 8. In order to improve the sewage discharge efficiency, a pump can be installed on one side of the sewage pipe 3 to facilitate the rapid removal of pollutants in the sewage pipe 3.

[0034] The bottom of the guide tube 21 is penetrated by the horn groove 7 and fixedly installed with a water inlet pipe 4. When clean water is needed in the sewage sedimentation process, clean water can be injected into the guide tube 21 through the water inlet pipe 4 to assist the sewage sedimentation;

[0035] Therefore, when sewage is being precipitated, after the staff injects sewage into the tank body 1, the heavier pollutants will be deposited at the bottom of the tank body 1 and accumulated at the horn groove 7. At this time, the staff can start the pump. After the pump is started, the sewage pipe 3 generates suction, and the pollutants accumulated at the bottom of the tank body 1 are discharged through the sewage outlet 8 and the sewage pipe 3;

[0036] During this process, the staff can also start the driving device 22, which drives the guide tube 21 to rotate, and simultaneously drives the lower auxiliary flow rod 23 and the upper auxiliary flow rod 26 to rotate synchronously. The lower auxiliary flow rod 23 scrapes off the pollutants adhering to the bottom of the pool body 1, while the upper auxiliary flow rod 26 sweeps away the lighter pollutants floating on the sewage.

[0037] After a series of sewage discharge, the staff can inject clean water into the guide tube 21 through the water inlet pipe 4. As the clean water is injected, the water level in the tank body 1 will rise, and the sewage containing less pollutants will overflow into the clean water channel 25 and finally be discharged through the drain port 5 to collect the settled sewage.

[0038] However, since the heavier pollutants are all discharged from the sewage outlet 8, and the cost of the pollutants inside is also more complicated due to the different types of sewage, when the sewage contains larger particles or more silt, the horn groove 7 and the sewage outlet 8 are prone to blockage. In order to solve this problem, Figure 2-Figure 3As shown, a cleaning assembly 6 for filtering particulate matter and cleaning the horn groove 7 is installed at the horn groove 7. The cleaning assembly 6 includes a fixed sleeve 61 with a bearing mounted on the surface of the guide cylinder 21. When the guide cylinder 21 rotates, the fixed sleeve 61 does not rotate.

[0039] A return spring 62 is fixedly mounted on the bottom of the fixed sleeve 61, and a sliding sleeve 63 is fixedly mounted on the bottom of the return spring 62. It should be noted that a sleeve (not shown in the figure) is also bearing-mounted on the surface of the guide cylinder 21, and the sliding sleeve 63 is slidably mounted on the surface of the sleeve. When subjected to external force, the sliding sleeve 63 is suitable for sliding up and down on the surface of the sleeve;

[0040] A filter plate 64 is fixedly mounted on the outer ring of the sliding sleeve 63. The surface of the filter plate 64 is provided with a plurality of filter holes 641. The filter plate 64 is mainly used to filter out larger pollutants to prevent them from reaching the bottom of the filter plate 64 and then entering the horn groove 7, thereby clogging the horn groove 7. The outer ring of the filter plate 64 is fixedly connected to the top of the inner wall of the horn groove 7, so that pollutants need to pass through the filter plate 64 before entering the horn groove 7.

[0041] In the present application, the filter plate 64 is made of a rubber material, which is elastic. In the initial state, due to the elastic action of the return spring 62, the sliding sleeve 63 is located near the fixed sleeve 61, and the surface of the filter plate 64 is inclined downward along a position away from the fixed sleeve 61. Since the pollutants entering the horn groove 7 need to pass through the filter plate 64 first, the pollutants accumulated on the filter plate 64 will flow downward along the surface of the filter plate 64, and then slide along the inner wall of the horn groove 7 to the bottom of the horn groove 7. The pollutants sliding down from the inner wall of the horn groove 7 will slide to the bottom of the horn groove 7 faster due to the inclined setting of the horn groove 7, and finally be discharged through the sewage outlet 8;

[0042] When a lot of pollutants accumulate, the filter plate 64 will deform due to gravity. Since its outer ring is fixed, and the center of the filter plate 64 is slidably connected to the sliding sleeve 63, the sliding sleeve 63 slides downward, and the return spring 62 stretches. For details, please refer to Figure 3 At this time, the pollutants on the filter plate 64 will slide toward the center of the filter plate 64 and fall from the center of the filter plate 64 along the filter holes 641 to the bottom of the horn groove 7. The pollutants will pass through the bottom of the horn groove 7 less, avoiding more silt adhering to the inner wall of the horn groove 7 and making it difficult to clean;

[0043] It should be noted that since sewage sedimentation is a long-term and continuous operation, the filter plate 64 may become clogged after a long period of operation, so the staff needs to clean the filter plate 64 to ensure that the filter holes 641 can remain unobstructed. When the filter plate 64 needs to be cleaned, the staff can directly enter the tank body 1 to clean the filter plate 64.

[0044] However, the filter plate 64 may be damaged after being used for a long time. To solve this problem, the outer ring of the filter plate 64 can be connected to the top of the horn groove 7 by bolts, and the connection between the inner ring of the filter plate 64 and the sliding sleeve 63 can also be changed to a bolt connection. Then, when the filter plate 64 needs to be replaced, the staff can first remove the bolts of the inner and outer rings of the filter plate 64, and then destroy the original damaged filter plate 64. Finally, the damaged filter plate 64 is removed from the horn groove 7, and the new filter plate 64 is reinstalled and locked with the bolts.

[0045] In summary, the above device uses the deformable filter plate 64 to screen out pollutants with larger particles and changes the flow direction of the pollutants, further reducing the risk of pollutants clogging the horn groove 7 and the sewage outlet 8.

[0046] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
