Description

Technical Field

[0001] This utility model relates to the field of filter bed cleaning technology, specifically a filter bed cleaning device. Background Technology

[0002] A filter is a device used for water treatment. It removes solid particles and impurities from water using specific filter media (such as sand and activated carbon) to purify the water. Backwashing is a maintenance process for filters. It involves using a reverse flow of water, usually pushing clean water or gas from the bottom of the filter to remove deposits and dirt from the filter media, thereby restoring filtration efficiency. This process typically involves stopping normal filtration, starting the flushing pump, adjusting valves to switch the water flow direction, backwashing through the filter media, ensuring timely discharge of wastewater after flushing, and finally resuming normal filtration operation. Publication number CN216095399U discloses a V-type filter cleaning device. The V-type filter includes a drainage trough. The cleaning device includes a movable base, a lifting base, a cleaning roller, and a cleaning disc. The movable base is connected to a moving component. The lifting base has an air inlet chamber connected to an air inlet hose. Air outlet chambers are located on both sides of the air inlet chamber, connected to air outlet pipes. The air outlet chamber and the air inlet chamber are separated by a partition with through holes. A rotating shaft is located inside the air outlet chamber, and a vortex component is mounted on the shaft. The cleaning roller is connected to the lifting base and a first transmission gear is connected to it. The cleaning disc is connected to the rotating shaft, and a second transmission gear is connected to it. Both the cleaning roller and the cleaning disc are equipped with cleaning bristles. This invention has a simple structure, is easy to use, and can achieve online cleaning of the V-type filter drainage trough, greatly reducing workload and improving cleaning efficiency.

[0003] However, during the filter cleaning process, this device may struggle to thoroughly remove deposits and particulate matter from the filter media surface. Furthermore, during backwashing, the water flow may not be strong enough to loosen firmly attached contaminants, leading to the filter media surface gradually becoming covered and reducing its filtration efficiency. To address these issues, the inventors have proposed a filter cleaning device. Utility Model Content

[0004] To address the problem that deposits and particulate matter on the surface of filter media may be difficult to thoroughly clean, the purpose of this invention is to provide a filter cleaning device.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a filter cleaning device, including a base, a water supply pipe installed at the top of the base, a connecting pipe installed on the water supply pipe, a flushing pump, a water flushing valve and a clean water valve connected to the outside of the water supply pipe respectively, a symmetrically distributed support frame installed at the top of the base, a symmetrically distributed vibrating steel plate installed on the inner wall of the top of the support frame, a rotating shaft rotatably provided on the inner wall of the top of the support frame, a swing plate fixedly provided on the outside of the rotating shaft, two hammer balls installed on the outside of the swing plate, a rotating rod rotatably provided inside the support frame, a rotating plate fixedly provided on the outside of the rotating rod, a fixed rod fixedly provided at the bottom of the rotating plate, a square groove opened in the swing plate, and the fixed rod movably inserted into the square groove.

[0006] Preferably, a bubble generator is installed on the outside of the connecting pipe, and an outlet pipe and an inlet pipe are respectively installed at the output end and input end of the bubble generator. The outlet pipe and the inlet pipe are connected to the connecting pipe through a flange.

[0007] Preferably, the base is equipped with feet arranged in a rectangular array at the bottom, and connecting flanges are fixed at both ends of the water pipe. Two vibrating steel plates are installed on the outside of the support frame by screws.

[0008] Preferably, a motor is installed at the top of the support frame, the motor output end is inserted through the support frame and fixedly connected to the rotating rod, and a protective box is installed at the top of the support frame, with the motor installed inside the protective box.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. In this utility model, by setting up a swing plate, a hammer ball, a vibrating steel plate and a rotating shaft and other structures to work together, the hammer ball can be driven to swing back and forth, thereby hammering the vibrating steel plate to vibrate. The vibration of the water driven by the vibrating steel plate not only increases the porosity of the filter material and improves the penetration of the water flow, thus ensuring that the backwash water can clean the entire filter layer evenly and effectively, but also significantly improves the cleaning efficiency, reduces the required rinsing time and reduces energy consumption.

[0011] 2. In this utility model, by setting up a bubble generator, an inlet pipe and an outlet pipe and other structures to work together, gas is introduced into the water flow during the backwashing process to form bubbles, which can significantly improve the power and impact of the water flow, effectively break up dirt and particles deposited on the surface of the filter media, and improve the uniformity and thoroughness of cleaning.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figure 1-4 As shown, this utility model provides a filter cleaning device, including a base 1, a water supply pipe 11 installed at the top of the base 1, a connecting pipe 12 connected to the water supply pipe 11, a flushing pump 13, a water flushing valve 14 and a clean water valve 15 connected to the outside of the water supply pipe 11 respectively. The flushing pump 13 transmits the pumped clean water to the bottom of the filter. The water flushing valve 14 is connected to the outlet pipe from the flushing pump 13 to input the water flow that needs to be backwashed. The clean water valve 15 is connected to the inlet of the filter body 4 to ensure that the clean water can flow smoothly into the filter for backwashing.

[0020] See Figure 2 In this application, both ends of the water pipe 11 are fixedly provided with connecting flanges 16, and the bottom of the base 1 is equipped with foot blocks 17 distributed in a rectangular array.

[0021] See Figure 2 The base 1 of this application is equipped with a symmetrically distributed support frame 2 at its top. The inner wall of the top of the support frame 2 is equipped with symmetrically distributed vibrating steel plates 21. The vibration of the vibrating steel plates 21 can cause the water source to shake. The two vibrating steel plates 21 are installed on the outside of the support frame 2 by screws. The vibrating steel plates 21 are in contact with the water source in the filter body 4, causing the vibrating steel plates 21 to vibrate.

[0022] See Figure 2 The support frame 2 of this application has a rotating shaft 22 on the inner wall of the top end. The rotating shaft 22 is used to support the swing plate 23 to swing. The swing plate 23 is fixed on the outside of the rotating shaft 22. Two hammer balls 24 are installed on the outside of the swing plate 23, so that the hammer balls 24 on both sides can hammer the vibrating steel plates 21 on both sides, thereby causing the water source to shake.

[0023] See Figure 2 The support frame 2 of this application has a rotating rod 26 rotatably mounted inside, a rotating plate 27 fixedly mounted on the outside of the rotating rod 26, a fixed rod 28 fixedly mounted at the bottom of the rotating plate 27, a square groove 25 opened in the swing plate 23, and the fixed rod 28 is movably inserted into the square groove 25; a motor 29 is installed at the top of the support frame 2, the output end of the motor 29 is inserted through the support frame 2 and fixedly connected to the rotating rod 26, a protective box 18 is installed at the top of the support frame 2, and the motor 29 is installed inside the protective box 18.

[0024] See Figure 2 A bubble generator 3 is installed on the outside of the connecting pipe 12 of this application. The bubble generator 3 is of the NZ-NM series. The output end and input end of the bubble generator 3 are respectively installed with a liquid outlet pipe 32 and a liquid inlet pipe 31. The liquid outlet pipe 32 and the liquid inlet pipe 31 are connected to the connecting pipe 12 through flanges.

[0025] See Figure 4 The filter body 4 of this application includes a filtration zone 41, a V-shaped plate 42, a collection chamber 43, and an inlet tank 44, etc.

[0026] See Figure 4 The filtration zone 41 of this application is provided with a filter media layer to filter the water source, while backwashing is mainly used to clean the impurities attached to the outside.

[0027] The working principle of this application is as follows: First, the flushing pump 13 is connected to a clean water source (such as a water storage tank or water tank) to draw clean water into the filter body 4. At this time, the flushing pump 13 backwashes the water into the filter body 4. The incoming water washes the filter media in reverse, thereby cleaning the impurities on the outside of the filter media. The washing water enters the V-shaped plate 42, and then enters the collection chamber 43 and the inlet tank 44 in sequence to complete the collection of the washing wastewater. The backwashing is completed when the discharged water is clear.

[0028] During the water delivery process, the bubble generator 3 is activated, causing it to start working. The gas (usually air) from the bubble generator 3 is injected into the liquid to form small bubbles. A portion of the liquid is injected into the bubbles and then enters the filter body 4. This allows the bubbles to significantly enhance the power and impact of the water flow, effectively breaking down the dirt and particles deposited on the surface of the filter media, thus improving the uniformity and thoroughness of the cleaning.

[0029] At the same time, the motor 29 is started, causing it to work. The output of the motor 29 rotates, driving the rotating rod 26 to rotate. The rotating rod 26 rotates, driving the rotating plate 27 to rotate. The rotating plate 27 rotates, causing the fixed rod 28 to swing. The swinging of the fixed rod 28 drives the swinging plate 23 to swing around the rotating shaft 22 through the square groove 25. The swinging of the swinging plate 23 drives the two hammer balls 24 on the outside to swing, causing the hammer balls 24 to hammer the vibrating steel plates 21 on both sides. This causes the vibrating steel plates 21 to vibrate in the water source within the filter body 4. The vibration of the water driven by the vibrating steel plates 21 not only increases the porosity of the filter media and improves the penetration of the water flow, thus ensuring that the backwash water can clean the entire filter layer evenly and effectively, but also significantly improves the cleaning efficiency, reduces the required rinsing time, and reduces energy consumption.

[0030] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
