Description

Technical Field

[0001] The utility model belongs to the technical field of urban sewage treatment, and particularly relates to a structure for clearing impurities in urban sewage sedimentation. Background Art

[0002] Urban sewage treatment refers to a series of physical, chemical, and biological treatment processes to remove pollutants in urban sewage to protect the water environment and public health. The treatment process usually includes steps such as pretreatment, primary treatment, secondary treatment, advanced treatment, and sludge treatment. Pretreatment aims to remove large particulate solids and floating objects. Primary treatment removes suspended solids through sedimentation. Secondary treatment uses biodegradation to remove organic matter. Advanced treatment further improves water quality. Sludge treatment involves treating and disposing of the sludge generated during the treatment process. Urban sewage treatment technologies mainly include physical treatment technologies, chemical treatment technologies, physicochemical treatment technologies, and biological treatment technologies. Physical treatment technologies include sedimentation, filtration, and air flotation. Chemical treatment technologies involve neutralization, dosing coagulation, etc. Biological treatment technologies include the activated sludge method and the biofilm method, etc.

[0003] Currently, after the urban sewage undergoes flocculation sedimentation, a large amount of impurities will accumulate in the sedimentation tank. Generally, the impurities in the sedimentation tank are treated by direct discharge. However, due to the flocculated substances contained in the impurities, the various impurities will adhere to each other, resulting in the accumulation of impurities in one piece and making it difficult to directly discharge. Based on this, a structure for clearing impurities in urban sewage sedimentation is proposed. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a structure for clearing impurities in urban sewage sedimentation with simple structure and reasonable design to solve the above problems.

[0005] The utility model realizes the above purpose through the following technical solutions:

[0006] A structure for clearing impurities in urban sewage sedimentation includes a sedimentation tank, and further includes:

[0007] A fixed frame fixedly connected to the top of the sedimentation tank. A motor is installed in the middle of the top of the fixed frame. The output end of the motor is fixedly connected to a rotating shaft. A cleaning plate is fixedly connected to the rotating shaft. A cleaning frame is fixedly connected to the bottom of the cleaning plate. A dredging frame is fixedly connected to the cleaning frame.

[0008] Among them, the cleaning frame is fixedly connected to the rotating shaft, and the cleaning frame fits on the inner wall of the sedimentation tank.

[0009] As a further optimized scheme of the utility model, a magnetic plate is fixedly connected to the cleaning plate. A conveying blade is fixedly connected to the bottom of the rotating shaft. The rotating shaft penetrates through the fixed frame and is rotatably connected to the fixed frame.

[0010] As a further optimized solution of the present utility model, a baffle is fixedly connected to the inner wall of the sedimentation bucket. One side of the baffle is the water inlet side, and the other side is the water drainage side. A filter screen is slidably connected to the water drainage side of the baffle, and a magnetic block is fixedly connected to the filter screen.

[0011] As a further optimized solution of the present utility model, a fixing plate is fixedly connected to the inner wall of the sedimentation bucket. A shaking spring is fixedly connected to the bottom of the fixing plate, and the shaking spring is fixedly connected to the top of the filter screen. The fixing plate is also fixedly connected to the water drainage side of the baffle, and the filter screen is slidably connected to the inner wall of the sedimentation bucket.

[0012] As a further optimized solution of the present utility model, the magnetic block and the magnetic plate are adapted to each other, and the rotating shaft penetrates through the filter screen and fits with the filter screen.

[0013] As a further optimized solution of the present utility model, a water inlet pipe and a drain pipe are fixedly connected to the fixing frame. The water inlet pipe is arranged on the water inlet side of the baffle, and the drain pipe is arranged on the water drainage side of the baffle. A waste discharge pipe is fixedly connected to the bottom of the sedimentation bucket. A valve is installed at the discharge end of the waste discharge pipe, and the conveying blade is located in the waste discharge pipe.

[0014] The beneficial effects of the present utility model are as follows: Through the combined use of the cleaning frame, the dredging frame and the conveying blade, when removing the impurity sediment, the rotation of the cleaning frame enables the cleaning frame to scrape the inner bottom of the sedimentation bucket.

[0022] Embodiment

[0023] As Figure 1 、 Figure 2 、 Figure 4 and Figure 5 shown, an urban sewage impurity precipitation and removal structure includes a precipitation bucket 1, and further includes: a fixing frame 6 fixedly connected to the top of the precipitation bucket 1, a motor 801 installed in the middle of the top of the fixing frame 6, an output end of the motor 801 fixedly connected to a rotating shaft 802, a cleaning plate 803 fixedly connected to the rotating shaft 802, a cleaning frame 805 fixedly connected to the bottom of the cleaning plate 803, a dredging frame 806 fixedly connected to the cleaning frame 805, wherein the cleaning frame 805 is fixedly connected to the rotating shaft 802, the cleaning frame 805 is attached to the inner wall of the precipitation bucket 1, a magnetic plate 804 is fixedly connected to the cleaning plate 803, a conveying blade 807 is fixedly connected to the bottom of the rotating shaft 802, and the rotating shaft 802 penetrates through the fixing frame 6 and is rotatably connected to the fixing frame 6.

[0024] As Figures 1 - 5As shown in the figure, a baffle 701 is fixedly connected to the inner wall of the sedimentation bucket 1. One side of the baffle 701 is the water inlet side, and the other side is the water drainage side. A filter screen 702 is slidably connected to the water drainage side of the baffle 701. A magnetic block 705 is fixedly connected to the filter screen 702. A fixing plate 704 is fixedly connected to the inner wall of the sedimentation bucket 1. A shaking spring 703 is fixedly connected to the bottom of the fixing plate 704. The shaking spring 703 is fixedly connected to the top of the filter screen 702. The fixing plate 704 is also fixedly connected to the water drainage side of the baffle 701. The filter screen 702 is slidably connected to the inner wall of the sedimentation bucket 1. The magnetic block 705 is adapted to a magnetic plate 804. A rotating shaft 802 penetrates through the filter screen 702 and is in contact with the filter screen 702. A water inlet pipe 4 and a drain pipe 5 are fixedly connected to the fixing frame 6. A water pump is installed at the water inlet end of the water inlet pipe 4, and a water pump is installed at the water drainage end of the drain pipe 5. The water inlet pipe 4 is arranged on the water inlet side of the baffle 701, and the drain pipe 5 is arranged on the water drainage side of the baffle 701. A waste discharge pipe 2 is fixedly connected to the bottom of the sedimentation bucket 1. A valve 3 is installed at the discharging end of the waste discharge pipe 2. The valve 3 is electrically driven. A conveying blade 807 is located in the waste discharge pipe 2.

[0025] During use, urban sewage that needs to be sedimented is added into the sedimentation bucket 1 through the water inlet pipe 4. The urban sewage flows through the filter screen 702 after being blocked by the baffle 701 and flows to the top of the filter screen 702 until the entire sedimentation bucket 1 is filled with urban sewage. The filter screen 702 can filter the urban sewage, making the water at the top of the filter screen 702 relatively clean water. Then, the sewage in the sedimentation bucket 1 is left to stand.

[0026] After reaching the specified standing time, the sedimented urban sewage in the sedimentation bucket 1 is discharged through the drain pipe 5. After the discharge is completed, the valve 3 is opened so that the waste discharge pipe 2 can discharge the impurity sediment. Then, the motor 801 is started to drive the rotating shaft 802 to drive the cleaning plate 803 and the cleaning frame 805 to rotate. As a result, the dredging frame 806 rotates with the rotation of the cleaning frame 805 where it is located. When the cleaning frame 805 rotates, it will scrape the inner wall of the sedimentation bucket 1, and the rotation of the dredging frame 806 will break the impurities that adhere together, improving the fluidity of the impurities. At the same time, the rotation of the rotating shaft 802 will also drive the conveying blade 807 to rotate, causing the conveying blade 807 to discharge the scraped and broken impurities through the waste discharge pipe 2.

[0027] This prevents the accumulation of impurities from making it difficult to remove the impurities at the bottom of the sedimentation bucket 1, ensuring the quality and efficiency of removing the impurities at the bottom of the sedimentation bucket 1.

[0028] And during this process, the rotation of the cleaning plate 803 will clean the bottom of the filter screen 702. At the same time, when the magnetic plate 804 provided on the cleaning plate 803 rotates to the position where the magnetic block 705 is located, the filter screen 702 will move upward under the action of the repulsive force, squeezing the jitter spring 703. When the magnetic plate 804 disengages from the position where the magnetic block 705 is located, at this time, the filter screen 702 will vibrate downward under the action of the jitter spring 703 and impact the cleaning plate 803, causing the filter screen 702, the cleaning plate 803, the cleaning frame 805 and the dredging frame 806 to vibrate, so that the impurities adhered to the filter screen 702 can be shaken off. At the same time, it prevents impurities from adhering to the cleaning frame 805 and the dredging frame 806 from affecting the cleaning efficiency of the impurities at the bottom of the sedimentation tank 1, further ensuring the cleaning efficiency and cleaning quality of the impurities at the bottom of the sedimentation tank 1, and at the same time ensuring the cleanliness of the sedimentation tank 1 when the urban sewage is sedimented again;

[0029] After the impurities inside the sedimentation tank 1 are cleaned, turn off the motor 801 and make the valve 3 block the waste discharge pipe 2, then the next sedimentation operation can be carried out.

[0030] The above embodiments only represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
