Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, and in particular to a multi-stage vibration anti-siltation filter device for water conservancy projects. Background Technology

[0002] During the operation of water conservancy projects, pumping station systems, and large-scale water supply facilities, raw water often contains a large amount of impurities such as silt, leaves, and aquatic plants. If these impurities are not effectively intercepted at the initial stage of water intake, they can easily cause blockages, wear, or even failures in subsequent pipes, valves, pumps, and other equipment, affecting the overall system's operational stability and water supply safety. Therefore, filtration devices are often installed before the water enters the main water supply system to filter the water.

[0003] As shown in the reference case "A Water Filtration Device" (Announcement No. CN210085124U), the scraper slides in the groove on the inner wall of the outer shell through the sliders on the front and rear sides, causing the scraper to slide down at an angle. This allows the scraper to remove impurities adhering to the upper surface of the inclined plate, and the impurities fall into the slag outlet through the inclined plate and are discharged. This facilitates the cleaning of impurities adhering to the inner wall and also facilitates the cleaning of the entire device later.

[0004] In practical applications, the raw water in the water conservancy system has a large impurity content and strong silt viscosity, which fluctuates significantly, especially during the rainy season or dry season. Simply scraping the structure is not enough to completely clean the sediment adhering to the filter screen, which makes the filter screen prone to clogging and failure. Utility Model Content

[0005] Based on this, it is necessary to address the problem that in practical applications, the raw water in water conservancy systems has a high impurity content and strong silt viscosity, especially with significant fluctuations during the rainy or dry seasons. Simple scraping structures are insufficient to thoroughly clean the sediment adhering to the filter screen, leading to filter screen clogging and failure. Therefore, a multi-stage vibration anti-siltation filtration device for water conservancy projects is provided, comprising: a filter box, with connecting water pipes fixedly installed on both sides of the filter box; and an anti-siltation filtration mechanism, which is disposed inside the filter box to prevent clogging. The anti-siltation filtration mechanism includes multiple filter plates disposed inside the filter box, and an anti-clogging component is provided inside the filter box, with a movable component on one side of the anti-clogging component.

[0006] In one embodiment, the anti-clogging component includes a rotating ring rotatably installed inside the filter box, a plurality of filter plates being fixedly installed on the surface of the rotating ring, the plurality of filter plates being arranged in a ring-like manner, the plurality of filter plates being located at one end of two adjacent connecting water pipes, a movable plate being provided inside the filter box, two support plates being fixedly installed on one side of the movable plate, the two support plates being located on one side of the plurality of filter plates respectively, a guide plate being fixedly installed on the surface of the support plate, and a plurality of high-pressure nozzles being fixedly installed on one side of the guide plate.

[0007] In one embodiment, the support plate is configured as an arc shape, and two vibrators are fixedly mounted on the surface of the support plate. A vibrating plate is rotatably mounted on the output end of the vibrator, and the vibrating plate is located on one side of an adjacent filter plate.

[0008] In one embodiment, one side of the vibrating plate is configured as a semi-circular shape, and the two vibrating plates are respectively located on both sides of the guide plate.

[0009] In one embodiment, the movable component includes a motor fixedly mounted inside the filter box, the output of which is fixedly connected to one side of the movable plate.

[0010] In one embodiment, a guide ring is fixedly installed inside the filter box. The guide ring has an internal hollow structure. A movable ring is rotatably installed on the surface of the guide ring. The movable ring is connected to the inside of the guide ring. A water inlet pipe is fixedly connected to one side of the guide ring. Both guide plates are connected to the movable ring.

[0011] In one embodiment, two input tubes are fixedly mounted on the surface of the movable ring, and the other ends of the two input tubes are respectively fixedly connected to two guide plates.

[0012] In one embodiment, the plurality of high-pressure nozzles are equidistantly distributed and are located between the plurality of filter plates.

[0013] Beneficial effects

[0014] The above-mentioned water conservancy projects use multi-stage vibration anti-siltation filtration devices:

[0015] 1. When the working filter plate becomes clogged or its efficiency decreases, the spare filter plate can be switched to the working position by rotation, realizing online replacement without stopping the machine; the replaced filter plate is moved to the anti-clogging component, which removes impurities such as mud and water plants from the surface to prevent clogging and accumulation; the moving component drives the anti-clogging component to move, adjust the cleaning position, and improve the cleaning range and effect;

[0016] 2. After the motor starts, it drives the movable plate to swing back and forth at a small angle, which drives the vibrating plate and the high-pressure nozzle to move synchronously, so that the vibration cleaning and rinsing process covers different areas of the filter plate, improves the cleaning coverage and eliminates dead corners.

[0030] The following is combined with Figures 1-5 This utility model describes a multi-stage vibration anti-siltation filtration device for water conservancy projects.

[0031] In one embodiment, a multi-stage vibration anti-siltation filtration device for hydraulic engineering, such as Figure 1As shown, the multi-stage vibration anti-siltation filtration device for water conservancy projects in this embodiment includes: a filter box 100, with connecting water pipes 200 fixedly installed on both sides of the filter box 100; an anti-siltation filtration mechanism 300, which is disposed inside the filter box 100 to prevent siltation and clogging; wherein, the anti-siltation filtration mechanism 300 includes multiple filter plates 310 disposed inside the filter box 100, an anti-clogging component 320 is disposed inside the filter box 100, and a moving component 330 is disposed on one side of the anti-clogging component 320.

[0032] In this embodiment, the filter box 100 is installed at the front end of the water intake or upstream of the water pump inlet in the water conservancy project. It is used to perform preliminary impurity interception treatment before the raw water enters the main water supply system or the booster pump station. Multiple filter plates 310 are arranged in a ring inside the filter box 100 to form an alternating working structure. Only two filter plates 310 are used for filtration at a time, while the remaining two filter plates 310 are in standby or waiting to be cleaned. When the working filter plate 310 becomes clogged or the filtration efficiency decreases, the standby filter plate 310 can be switched to the working position by rotation, realizing online replacement without stopping the machine. The replaced filter plates 310 can be moved to one side of the anti-clogging component 320 in sequence. The anti-clogging component 320 cleans the mud, sand, aquatic plants and other impurities attached to its surface, effectively avoiding the accumulation of blockage. The moving component 330 drives the anti-clogging component 320 to move, thereby realizing the relative position adjustment of the filter plates 310, expanding the cleaning range and improving the cleaning effect.

[0033] It should be noted that existing filtration devices typically include basic components such as a filter box 100, a water flow channel, a fixed filter screen, and an impurity collection port. The anti-clogging component 320 and the moving component 330, which are set inside the filter box 100, are structurally independent of the water flow channel. They only participate in the cleaning process after the filter plate 310 is switched to a non-working state, without changing the main water flow path or the normal filtration state of the filter plate 310. The filter plate 310 maintains a sealed fit with the inner cavity of the filter box 100 during rotation. The moving component 330 drives the anti-clogging component 320 to move locally without contacting or interfering with the interface structure of the main water flow channel and the connecting water pipe 200. Therefore, the setting of the anti-clogging component 320 and the moving component 330 will not affect the normal use of the filtration device and the stable flow process of the water.

[0034] like Figure 2 , Figure 3 and Figure 4As shown, the anti-clogging component 320 includes a rotating ring 321 rotatably installed inside the filter box 100. Multiple filter plates 310 are fixedly installed on the surface of the rotating ring 321. The multiple filter plates 310 are arranged in a ring shape and are located at the adjacent ends of two connecting water pipes 200. A movable plate 327 is provided inside the filter box 100. Two support plates 322 are fixedly installed on one side of the movable plate 327. The two support plates 322 are located on one side of the multiple filter plates 310 respectively. A guide plate 323 is fixedly installed on the surface of the support plate 322. Multiple high-pressure nozzles 324 are fixedly installed on one side of the guide plate 323.

[0035] In this embodiment, the rotating ring 321 is used to support multiple filter plates 310. The multiple filter plates 310 are distributed in a ring shape along its surface and can rotate as a whole with the rotating ring 321 to realize the switching between working filter plates 310 and filter plates 310 to be cleaned. When the two filter plates 310 are switched to the state to be cleaned, multiple high-pressure nozzles 324 perform directional high-pressure water flow rinsing on the surface of the filter plates 310, effectively removing silt, aquatic plants, impurity particles and other attachments adhering to the filter screen, and achieving a cleaning effect.

[0036] The support plate 322 is set in an arc shape. Two vibrators 325 are fixedly installed on the surface of the support plate 322. A vibrating plate 326 is rotatably installed at the output end of the vibrator 325. The vibrating plate 326 is located on one side of the adjacent filter plate 310.

[0037] In this embodiment, the support plate 322 is set in an arc shape, which can better fit the curved contour of the filter plate 310. When the vibrator 325 is working, it drives the vibrating plate 326 to generate continuous disturbance, which can directly transfer the vibration energy to the filter plate 310 and achieve synchronous vibration effect. On the basis of high-pressure water flushing, a vibration auxiliary mechanism is introduced to effectively enhance the desorption effect of impurities on the filter screen.

[0038] It should be noted that the vibrator 325 is installed in a sealed protective housing. The vibrator 325 is a device that generates mechanical vibration force through the rotation of an internal eccentric rotor. It is often used to provide periodic or continuous vibration to external structures. In this device, the vibrator 325 is driven by a power source to rotate the internal eccentric shaft at high speed, which in turn drives the vibrating plate 326 connected to its output end to generate reciprocating vibration or disturbance impact. This vibration process can be transmitted to the surface of the filter plate 310 that is close to it, so that the silt, aquatic plants and fine impurities adhering to the filter screen are loosened and detached due to the periodic vibration.

[0039] One side of the vibrating plate 326 is set in a semi-circular shape, and the two vibrating plates 326 are located on both sides of the guide plate 323 respectively.

[0040] In this embodiment, the semi-circular shape of the vibrating plate 326 can fit the local curved surface shape of the filter plate 310, and can also generate a larger contact area with the filter plate 310 during vibration.

[0041] like Figure 2 , Figure 3 and Figure 5 As shown, the moving component 330 includes a motor 335 fixedly installed inside the filter box 100, and the output end of the motor 335 is fixedly connected to one side of the movable plate 327.

[0042] In this embodiment, when the motor 335 is started, it can drive the movable plate 327 to swing forward and backward at a small angle, thereby driving the vibrating plate 326 and the high-pressure nozzle 324 installed on it to move synchronously within the angle range. This allows the vibration cleaning and spray rinsing process to cover different areas of the filter plate 310 surface, enhancing the cleaning coverage and the ability to remove dead corners.

[0043] A guide ring 331 is fixedly installed inside the filter box 100. The guide ring 331 is designed with an internal hollow structure. A movable ring 332 is rotatably installed on the surface of the guide ring 331. The movable ring 332 is connected to the inside of the guide ring 331. A water inlet pipe 333 is fixedly connected to one side of the guide ring 331. Both guide plates 323 are connected to the movable ring 332.

[0044] In this embodiment, the guide ring 331 has a hollow structure and can be used as an internal water flow channel. The movable ring 332 is internally connected to the guide ring 331 and can be rotated and adjusted relative to the guide ring 331. A water inlet pipe 333 is fixedly connected to one side of the guide ring 331 for introducing high-pressure cleaning water. Both guide plates 323 are connected to the movable ring 332, so that the water flow required by the high-pressure nozzle 324 can form a closed water supply channel through the water inlet pipe 333, the guide ring 331, and the movable ring 332 and flow to the high-pressure nozzle 324. This can avoid affecting the use of the high-pressure nozzle 324 due to the adjustment of the anti-clogging component 320.

[0045] Two input tubes 334 are fixedly mounted on the surface of the movable ring 332, and the other ends of the two input tubes 334 are fixedly connected to two guide plates 323 respectively.

[0046] In this embodiment, high-pressure water flows into the guide ring 331 through the inlet pipe 333, and then is sequentially delivered to the two guide plates 323 through the movable ring 332 and the input pipe 334, forming a stable and continuous flushing water flow in conjunction with the high-pressure nozzle 324.

[0047] The multiple high-pressure nozzles 324 are equidistantly distributed and are located between the multiple filter plates 310.

[0048] In this embodiment, since the high-pressure nozzles 324 are evenly distributed and the spray angle is consistent with the cleaning intensity, it can be ensured that each set of filter plates 310 receives a balanced and efficient cleaning treatment after rotating to the cleaning area.

[0049] Working principle: Raw water enters the filter box 100 through the connecting water pipe 200 and is filtered by two filter plates 310 in the working position, intercepting impurities such as silt and aquatic plants. The purified water is discharged through the other connecting water pipe 200. When the filter plates 310 accumulate more impurities and the filtration efficiency decreases, the spare filter plate 310 can be rotated to the working position by rotating the rotating ring 321 to complete the online switching and ensure continuous filtration. The replaced filter plate 310 is rotated to the corresponding area of ​​the anti-clogging component 320 and fixed by the support plate 322. Then, it is directionally flushed by the high-pressure nozzle 324 on the guide plate 323 to remove surface impurities. Impurities are removed, and the vibrator 325 drives the vibrating plate 326 to contact and vibrate the filter plate 310, causing the attached substances to loosen. Combined with the water flow, the cleaning efficiency is further improved. The motor 335 drives the movable plate 327 to reciprocate at a small angle, causing the cleaning area of ​​the vibrating plate 326 and the high-pressure nozzle 324 to swing accordingly, expanding the cleaning coverage and avoiding dead corners. The cleaning water enters the guide ring 331 through the water inlet pipe 333, and then is transported to the guide plate 323 through the movable ring 332 and the input pipe 334. It is then sprayed evenly by the high-pressure nozzle 324. Multiple high-pressure nozzles 324 are equidistantly arranged between the filter plates 310 to form a stable and uniform rinsing effect.

[0050] It should be noted that the high-pressure nozzles, vibrators, and motors mentioned above are all devices with relatively mature existing technologies. Specific models can be selected according to actual needs. At the same time, the high-pressure nozzles, vibrators, and motors can be powered by built-in power supplies or by mains power. The specific power supply method should be selected according to the situation, and will not be elaborated here.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
