Description
Technical Field
[0001] This utility model relates to the technical field of sediment filtration devices, and in particular to a sediment filtration device for water conservancy projects. Background Technology
[0002] Sediment filtration devices are used in water conservancy projects to filter sediment in water. The device consists of a filter tank, inlet, outlet, sand storage tank, sand discharge pipe, and valves. When using the device, the worker fixes the external water pipe to the inlet, allowing water to be pumped into the filter tank. Under a certain pressure, the water flows tangentially into the equipment from the inlet, generating a strong rotational motion. Due to the different densities of sand and water, under the action of centrifugal force, centripetal force, buoyancy, and fluid drag, the less dense water rises and is discharged from the outlet, while the denser sand particles fall into the sand storage tank. During sand discharge, the valve is opened, allowing the sand to be discharged through the sand discharge pipe.
[0003] In their daily work, the inventors discovered that when using a sediment filtration device, in order to filter out sediment from the water as much as possible, a filter screen is usually installed at the outlet after the filter tank for further filtration. However, when water comes out of the outlet, there may be a small amount of sediment particles in the water that are about the same size as the filter screen pores, which can enter the filter screen pores. Due to the sharp edges of the sediment particles, they may get stuck in the filter screen pores and cause blockage, which may affect the filtration efficiency. Utility Model Content
[0004] The purpose of this utility model is to solve the problem that in actual use, in order to filter out as much mud and sand as possible in the water, a filter screen is usually installed at the outlet after the filter tank is used for further filtration. However, when the water comes out of the outlet, there may be a small amount of mud and sand particles in the water that are about the same size as the filter screen pores. These particles can enter the filter screen pores, but due to the sharp edges of the mud and sand particles, they may get stuck in the filter screen pores and cause blockage, which may affect the filtration efficiency. Therefore, a mud and sand filtration device for water conservancy projects is proposed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a sediment filtration device for water conservancy projects, comprising a filter tank, a sand storage tank fixedly connected to the lower end of the filter tank, an installation frame fixedly connected to the lower end of the sand storage tank, a sand discharge pipe fixedly connected to the arc surface of the sand storage tank, a valve installed on the arc surface of the sand discharge pipe, a water inlet fixedly connected to the arc surface of the filter tank, an installation pipe fixedly connected to the upper end of the filter tank, a connecting pipe fixedly connected to the upper end of the installation pipe, a component for easy replacement provided on the arc surface of the connecting pipe, a water outlet fixedly connected to the upper end of the connecting pipe, an anti-clogging component provided on the inner wall of the installation pipe, the anti-clogging component comprising a rotating rod and a driving mechanism disposed on the inner wall of the installation pipe, a sliding plate slidably connected to the inner wall of the rotating rod, bristles fixedly connected to the upper end of the sliding plate, the bristles being flexible, and the driving mechanism used to control the rotation of the rotating rod.
[0006] The effect achieved by the above components is as follows: by setting up anti-clogging components, when it is necessary to prevent the filter screen from clogging, the drive mechanism causes the rotating rod to rotate, which causes the bristles on the sliding plate to rotate. The bristles rotate on the filter screen and enter the filter screen to poke out the clogging mud and sand, thereby minimizing the impact of filter screen clogging on the filtration efficiency.
[0007] Preferably, a spring is fixedly connected to the lower end of the slide plate, and the other end of the spring is fixed to the rotating rod.
[0008] The effect achieved by the above components is as follows: by setting a spring, when the brush bristles come into contact with the filter screen, the spring is compressed, so that the spring has a reverse force, pushing the slide plate, so that the brush bristles come into full contact with the filter screen.
[0009] Preferably, the driving mechanism includes a mounting component fixedly connected to the inner wall of the mounting tube, and the inner wall of the mounting component is provided with a rotating shaft rotatably connected by means of a bearing, wherein the rotating shaft and the rotating rod are fixed.
[0010] The effect achieved by the above components is that the rotating shaft on the mounting piece rotates, causing the rotating rod to rotate.
[0011] Preferably, a connecting rod is fixedly connected to the arc surface of the rotating shaft, and a rotating blade is fixedly connected to the other end of the connecting rod.
[0012] The effect achieved by the above components is that when water enters from the inlet and is sprayed into the filter tank, it causes the rotating blades to rotate, thereby causing the shaft on the mounting to rotate.
[0013] Preferably, the easy-to-replace component includes a mounting block inserted into the arc surface of the connecting pipe, and a filter screen is fixedly connected to the inner arc surface of the mounting block.
[0014] The effect achieved by the above components is that when it is necessary to easily replace the filter screen, the mounting block can be dragged to separate it from the connecting pipe, thereby pulling out the filter screen and replacing it with a new one, thus making it as convenient as possible to replace the filter screen.
[0015] Preferably, the connecting pipe has arc-shaped mounting plates on both sides of its arc surface, and the two arc-shaped mounting plates are fixed together by bolts.
[0016] The effect achieved by the above components is to fix the two arc-shaped mounting plates to the mounting block part of the connecting pipe with bolts, thereby fixing the mounting block.
[0017] Preferably, a sealing gasket is provided between the mounting block and the connecting pipe, and the rotating rod is located below the filter screen.
[0018] The effect achieved by the above components is to seal the space between the mounting block and the connecting pipe by setting a sealing gasket.
[0019] In summary, the beneficial effects of this utility model are as follows:
[0020] In this invention, by setting an anti-clogging component, when it is necessary to prevent the filter screen from clogging, the driving mechanism causes the rotating rod to rotate, which in turn causes the bristles on the sliding plate to rotate. The bristles rotate on the filter screen and enter the filter screen to poke out the clogging mud and sand, thereby minimizing the impact of filter screen clogging on the filtration efficiency. This solves the problem that in order to filter out as much mud and sand as possible, a filter screen is usually installed at the outlet after the filter tank for further filtration. However, when water comes out of the outlet, there may be a small amount of mud and sand particles in the water that are about the same size as the filter screen pores. These particles may enter the filter screen pores, but due to their own sharp edges, they may get stuck in the filter screen pores and cause clogging, which may affect the filtration efficiency.

[0026] Reference Figure 1 and Figure 2 As shown, this utility model provides a technical solution: a sediment filtration device for water conservancy projects includes a filter tank 1, a sand storage tank 4 fixedly connected to the lower end of the filter tank 1, an installation frame 5 fixedly connected to the lower end of the sand storage tank 4, a sand discharge pipe 6 fixedly connected to the arc surface of the sand storage tank 4, a valve 7 installed on the arc surface of the sand discharge pipe 6, a water inlet 8 fixedly connected to the arc surface of the filter tank 1, an installation pipe 11 fixedly connected to the upper end of the filter tank 1, a connecting pipe 10 fixedly connected to the upper end of the installation pipe 11, a replacement component 3 provided on the arc surface of the connecting pipe 10, a water outlet 9 fixedly connected to the upper end of the connecting pipe 10, and an anti-clogging component 2 provided on the inner wall of the installation pipe 11.
[0027] The following section will explain the specific settings and functions of the anti-clogging component 2 and the easy-to-replace component 3.
[0028] Reference Figure 2 and Figure 3As shown in this embodiment: the anti-clogging component 2 includes a rotating rod 21 and a driving mechanism 25 disposed on the inner wall of the mounting tube 11. A sliding plate 22 is slidably connected to the inner wall of the rotating rod 21. A brush bristle 23 is fixedly connected to the upper end of the sliding plate 22. The brush bristle 23 is flexible. The driving mechanism 25 is used to control the rotation of the rotating rod 21. By setting the anti-clogging component 2, when it is necessary to prevent the filter screen 32 from clogging, the driving mechanism 25 causes the rotating rod 21 to rotate, causing the brush bristle 23 on the sliding plate to rotate. The brush bristle 23 rotates on the filter screen 32 and enters the filter screen 32 to poke out the clogging mud and sand, thereby achieving the effect of avoiding the filter screen 32 from clogging and affecting the filtration efficiency of the filter screen 32 as much as possible. A spring 24 is fixedly connected to the lower end of the sliding plate 22. The other end of the spring 24 is connected to the rotating rod 21. The mechanism is fixed by setting a spring 24. When the brush bristles 23 come into contact with the filter screen 32, the spring 24 is compressed, which causes the spring 24 to exert a reverse force, pushing the slide plate 22 so that the brush bristles 23 can fully contact the filter screen 32. The drive mechanism 25 includes a mounting part 251 fixedly connected to the inner wall of the mounting tube 11. The inner wall of the mounting part 251 is provided with a rotating shaft 252 rotatably connected by a bearing. The rotating shaft 252 and the rotating rod 21 are fixed. When the rotating shaft 252 on the mounting part 251 rotates, the rotating rod 21 rotates. The arc surface of the rotating shaft 252 is fixedly connected to a connecting rod 253. The other end of the connecting rod 253 is fixedly connected to a rotating blade 254. When water enters from the inlet 8 and sprays out into the filter tank 1, it pushes the rotating blade 254 to rotate, thereby causing the rotating shaft 252 on the mounting part 251 to rotate.
[0029] Reference Figure 3 and Figure 4 As shown in this embodiment: the easy-to-replace component 3 includes a mounting block 31 inserted into the arc surface of the connecting pipe 10. A filter screen 32 is fixedly connected to the inner arc surface of the mounting block 31. When it is necessary to easily replace the filter screen 32, the mounting block 31 is dragged to separate it from the connecting pipe, thereby removing the filter screen 32 and replacing it with a new filter screen 32, thus maximizing the ease of filter screen replacement. Arc-shaped mounting plates 33 are provided on both sides of the arc surface of the connecting pipe 10. The two arc-shaped mounting plates 33 are fixed by bolts 34. The two arc-shaped mounting plates 33 are fixed to the mounting block 31 part of the connecting pipe 10 by bolts 34, thereby fixing the mounting block 31. A sealing gasket is provided between the mounting block 31 and the connecting pipe 10. The rotating rod 21 is located below the filter screen 32. By providing a sealing gasket, the mounting block 31 and the connecting pipe 10 are sealed.
[0030] Working principle:
[0031] When using the silt filtration device, the worker fixes the external water pipe to the inlet 8, allowing water to be pumped into the filter tank 1. Under a certain pressure, the water flows tangentially into the equipment from the inlet 8 of the filter tank 1, generating a strong rotational motion. Due to the different densities of sand and water, under the action of centrifugal force, centripetal force, buoyancy, and fluid drag, the less dense water rises and is discharged from the outlet 9, while the denser sand particles fall into the sand storage tank 4. During sand discharge, the valve 7 is opened, allowing the sand to be discharged through the discharge pipe 6. To prevent the filter screen 32 from clogging, when water enters from the inlet 8 and sprays out into the filter tank 1, it drives the rotating blade 254 to rotate, thereby causing the rotating shaft 252 on the mounting component 251 to rotate, which in turn causes the rotating rod 21 to rotate, causing the brush bristles 23 on the sliding plate to rotate. The brush bristles 23 rotate on the filter screen 32. The bristles 23 enter the filter screen 32 to poke out the blocked mud and sand, thereby minimizing the impact of filter screen 32 blockage on filtration efficiency. A spring 24 is provided; when the bristles 23 contact the filter screen 32, the spring 24 is compressed, causing the spring 24 to exert a counterforce, pushing the slide plate 22 to ensure full contact between the bristles 23 and the filter screen 32. When easy replacement of the filter screen 32 is needed, the mounting block 31 is dragged to separate from the connecting pipe, allowing the filter screen 32 to be removed and replaced with a new one, thus maximizing the convenience of filter screen replacement. Two arc-shaped mounting plates 33 are fixed to the mounting block 31 portion of the connecting pipe 10 using bolts 34, thus securing the mounting block 31. A sealing gasket is used to seal the space between the mounting block 31 and the connecting pipe 10.
