Description

Technical Field

[0001] The utility model belongs to the technical field of soil and water conservation, and in particular relates to a soil and water conservation sedimentation tank. Background Art

[0002] Hydrogeology refers to the various changes and movements of groundwater in nature. In the research and investigation of hydrogeological engineering, in order to prevent and control soil erosion caused by natural factors and human activities, some projects are often built. Soil and water conservation sedimentation tank is one of them, which can separate sand from water to prevent affecting the operation of subsequent treatment equipment.

[0003] The Chinese patent with application number CN202221543040.7 discloses a soil and water conservation sedimentation tank, including a sedimentation tank body and a filter plate that slides vertically inside the sedimentation tank body. The top of the sedimentation tank body is provided with a driving mechanism that drives the filter plate to move upward; the driving mechanism includes an installation box, a driving motor arranged inside the installation box, a storage wheel connected to the output end of the driving motor, and two first pull ropes wound on the storage wheel, one end of each of the two first pull ropes is fixedly connected to two second pull ropes, and one end of the second pull rope is fixedly connected to a corner of the top of the filter plate. It relates to the technical field of sedimentation tanks. The utility model allows the filter plate to slowly settle inside the sedimentation tank body under the action of its own gravity. When the filter plate is settling, the filter plate will drive the impurities and sand and mud in the sewage to settle downward, thereby accelerating the sedimentation of sand and soil, shortening the sedimentation cycle of sand and soil, and improving work efficiency.

[0004] However, when the existing sand settling tank is used for water and soil conservation, the sewage flows through the filter screen, which is easily blocked due to frequent filtering of mud, and the filtering effect will decrease accordingly, and the sand settling efficiency will decrease. It is necessary to manually remove the filter screen frequently for cleaning, which is time-consuming and laborious. Therefore, a soil and water conservation sand settling tank is improved and designed. Utility Model Content

[0005] In view of the above-mentioned deficiencies existing in the prior art, the utility model provides a soil and water conservation sedimentation tank to solve the problems in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A soil and water conservation sedimentation tank comprises a sedimentation tank, the top of which is open, a mud discharge pipe is arranged at the bottom of the sedimentation tank, a filter plate is movably arranged inside the sedimentation tank, and a plurality of filter holes are opened on the plate body of the filter plate;

[0008] A cleaning assembly for unclogging the filter holes is provided below the filter plate. The cleaning assembly includes a plurality of cleaning cones. The cleaning cones include connecting columns and cone heads. The cone heads are fixedly connected to the pool bottom via the connecting columns. The cone heads can penetrate into the clogged filter holes and push out the silt in the filter holes, thereby achieving the purpose of unclogging the filter holes.

[0009] By adopting the above structural design, the soil and water conservation sedimentation tank is provided with a filter plate that can be raised and lowered in the sedimentation tank, and a cleaning component for dredging the filter holes on the filter plate is provided below the filter plate. The cleaning component is composed of a cleaning cone. When in use, after the filter holes on the filter plate are blocked by sediment, sediment accumulates on the filter plate, the flow of water is also blocked, and the overall weight of the filter plate increases, causing the filter plate to move downward. After the filter plate moves downward, a contact cone head is opened. As the filter plate continues to move downward, the cone head begins to penetrate into the blocked filter holes and push out the sediment in the filter holes, thereby achieving the purpose of automatically dredging the filter holes.

[0010] Furthermore, the filter hole array is arranged on the filter plate, the number of the cleaning cones is the same as the number of the filter holes, each cleaning cone corresponds to one filter hole and is arranged directly below the filter hole.

[0011] Furthermore, positioning holes are opened at the four top corners of the filter plate, and guide rods are arranged in the positioning holes. The guide rods are fixedly connected to the bottom of the pool, and a spring is sleeved on the outer periphery of the guide rods. One end of the spring is fixedly connected to the filter plate, and the other end is fixedly connected to the bottom of the pool. The top of the guide rod is detachably connected to a limiting block.

[0012] Furthermore, the spring is a corrosion-resistant composite rubber spring.

[0013] By adopting the above structural design, positioning holes are opened at the four top corners of the filter plate, guide rods are arranged in the positioning holes, and a spring is connected to the bottom of the filter plate. When the filter holes of the filter plate are blocked, the weight on the filter plate increases, thereby compressing the spring to move downward. As the filter plate continues to move downward, the cone head begins to penetrate into the blocked filter holes and push out the sediment in the filter holes, thereby achieving the purpose of automatically unblocking the filter holes. When the filter holes are unblocked, they are automatically reset under the action of the spring.

[0014] Furthermore, a water inlet is provided at the upper portion of the grit chamber, a drain pipe is provided at the middle portion of the grit chamber, and the drain pipe is arranged above the filter plate.

[0015] Furthermore, the height of the spring is greater than the height of the cleaning cone, and the initial position of the filter plate is higher than the cleaning cone.

[0016] Furthermore, the limit block and the guide rod are threadedly connected to achieve a detachable connection.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] 1. The soil and water conservation sedimentation tank is provided with a filter plate that can be raised and lowered in the sedimentation tank, and a cleaning component for dredging the filter holes on the filter plate is provided below the filter plate. The cleaning component is composed of a cleaning cone. When in use, after the filter holes on the filter plate are blocked by sediment, sediment accumulates on the filter plate, and the flow of water is also blocked. The overall weight of the filter plate increases, causing the filter plate to move downward. After the filter plate moves downward, a contact cone head is opened. As the filter plate continues to move downward, the cone head begins to penetrate into the blocked filter holes and push out the sediment in the filter holes, thereby achieving the purpose of automatically dredging the filter holes;

[0019] 2. The four top corners of the filter plate are provided with positioning holes, in which guide rods are arranged. A spring is connected to the bottom of the filter plate. When the filter holes of the filter plate are blocked, the weight on the filter plate increases, thereby compressing the spring to move downward. As the filter plate continues to move downward, the cone head begins to penetrate into the blocked filter holes and push out the mud and sand in the filter holes, thereby achieving the purpose of automatically unblocking the filter holes. When the filter holes are unblocked, they automatically reset under the action of the spring. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Embodiment 1:

[0030] like Figure 1-3 Specifically, a soil and water conservation sedimentation tank comprises a sedimentation tank 1, the top of the sedimentation tank 1 is open, a mud discharge pipe 13 is arranged at the bottom of the sedimentation tank 1, a filter plate 2 is movably arranged inside the sedimentation tank 1, and a plurality of filter holes 21 are opened on the plate body of the filter plate 2; a cleaning assembly 3 for unblocking the filter holes 21 is arranged below the filter plate 2, and the cleaning assembly 3 comprises a plurality of cleaning cones 33, and the cleaning cone 33 comprises a connecting column 331 and a cone head 332, and the cone head 332 is fixedly connected to the pool bottom 14 through the connecting column 331, and the cone head 332 can penetrate into the blocked filter hole 21 to push out the silt in the filter hole 21, so as to achieve the purpose of unblocking the filter hole 21.

[0031] By adopting the above-mentioned structural design, the soil and water conservation sedimentation tank is provided with a filter plate 2 that can be raised and lowered in the sedimentation tank 1, and a cleaning component 3 for dredging the filter holes 21 on the filter plate 2 is provided below the filter plate 2. The cleaning component 3 is composed of a cleaning cone 33. When in use, after the filter holes 21 on the filter plate 2 are blocked by silt, silt accumulates on the filter plate 2, the flow of water is also blocked, and the overall weight of the filter plate 2 increases, causing the filter plate 2 to move downward. After the filter plate 2 moves downward, a contact cone head 332 is opened. As the filter plate 2 continues to move downward, the cone head 332 begins to penetrate into the blocked filter holes 21 and push out the silt in the filter holes 21, thereby achieving the purpose of automatically dredging the filter holes 21.

[0032] In this embodiment, the filter holes 21 are arranged in an array on the filter plate 2 , the number of the cleaning cones 33 is the same as the number of the filter holes 21 , and each cleaning cone 33 corresponds to one filter hole 21 and is arranged directly below the filter hole 21 .

[0033] In this embodiment, positioning holes 22 are opened at the four top corners of the filter plate 2, and a guide rod 31 is arranged in the positioning hole 22. The guide rod 31 is fixedly connected to the pool bottom 14. A spring 32 is sleeved on the outer periphery of the guide rod 31. One end of the spring 32 is fixedly connected to the filter plate 2, and the other end is fixedly connected to the pool bottom 14. The top of the guide rod 31 is detachably connected to a limiting block 311.

[0034] In this embodiment, the spring 32 is a corrosion-resistant composite rubber spring.

[0035] By adopting the above structural design, positioning holes 22 are opened at the four top corners of the filter plate 2, and guide rods 31 are arranged in the positioning holes 22. A spring 32 is connected to the bottom of the filter plate 2. When the filter hole 21 of the filter plate 2 is blocked, the weight on the filter plate 2 increases, thereby compressing the spring 32 to move downward. As the filter plate 2 continues to move downward, the cone head 332 begins to penetrate into the blocked filter hole 21 and push out the sediment in the filter hole 21, thereby achieving the purpose of automatically unblocking the filter hole 21. When the filter hole 21 is unblocked, it automatically resets under the action of the spring 32.

[0036] In this embodiment, a water inlet 11 is provided at the upper portion of the grit chamber 1 , a drain pipe 12 is provided at the middle portion of the grit chamber 1 , and the drain pipe 12 is disposed above the filter plate 2 .

[0037] In this embodiment, the height of the spring 32 is greater than the height of the cleaning cone 33 , and the initial position of the filter plate 2 is higher than the cleaning cone 33 .

[0038] In this embodiment, the stop block 311 and the guide rod 31 are threadedly connected to achieve a detachable connection. By adopting the above structural design, the stop block 311 can be removed from the top of the guide rod 31 and the filter plate 2 can be taken out.

[0039] Working principle: When using the soil and water conservation sedimentation tank, the sewage to be filtered is introduced into the sedimentation tank 1 from the top opening of the sedimentation tank 1 or the water inlet 11. The larger mud and gravel contained in the sewage will be blocked by the filter mesh 2 just above the tank body 1, so that the clean water and fine sand can pass through the filter plate 2 and settle at the bottom of the tank. The clean water after sedimentation can be discharged through the drain pipe 12 or a pumping mechanism such as a water pump, and the mud and sand can be discharged through the mud discharge pipe 13. A control valve is installed on the mud discharge pipe 13 to control the circulation. When the filter hole 21 of the filter plate 2 is blocked, the weight on the filter plate 2 increases, thereby compressing the spring 32 to move downward. As the filter plate 2 continues to move downward, the cone head 332 begins to penetrate into the blocked filter hole 21 and push out the mud and sand in the filter hole 21, thereby achieving the purpose of automatically unblocking the filter hole 21. When the filter hole 21 is unblocked, it automatically resets under the action of the spring 32.
