Description

Technical Field

[0001] The present invention belongs to the technical field of water quality treatment, and particularly relates to a self-cleaning gas floating fiber filter tank. Background Art

[0002] The treatment of raw water into tap water is a complex process, which usually includes multiple steps to ensure the safety and cleanliness of water quality, including a pretreatment stage, a filtration stage, a disinfection stage, etc. Among them, the filtration stage is crucial. In the filtration stage, through physical interception, suspended solids, colloids, organic matters, bacteria, viruses and other impurities in water are effectively removed, significantly improving water quality; if these impurities are not filtered, they will directly affect the clarity and safety of tap water and may even pose a hazard to human health.

[0003] In the filtration stage, fiber filter tanks are often used. It can remove most of the suspended solids and impurities in water in the filtration stage, providing a good water source for subsequent treatment processes. At the same time, in the advanced treatment stage, the fiber filter tank can further remove fine particles and microorganisms in water, improving the quality of the effluent. Therefore, it plays an important role in the process of treating raw water into tap water.

[0004] However, during the use of the fiber filter tank, impurities such as suspended solids, organic matters, and microorganisms will gradually accumulate. These impurities will reduce the filtration efficiency of the filter tank. There are currently situations where the cleaning method is inefficient and not thoroughly cleaned, which also affects the subsequent treatment effect of raw water. Summary of the Invention

[0005] The purpose of the present invention is to provide a self-cleaning gas floating fiber filter tank to solve the problems in the prior art that when cleaning the fiber filter tank, the cleaning is not in place, which not only prolongs the raw water treatment time but also reduces the subsequent raw water treatment efficiency.

[0006] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0007] A self-cleaning gas floating fiber filter tank. Inside the top surface of the filter tank near the water inlet, there is a bubble plate. The bubble plate is provided with uniformly distributed bubble outlets. A gas supply component is provided on the bubble plate. Above the bubble plate, there is a collection component for collecting the floating impurities. The installation frame is located on the side of the bubble plate away from the water inlet. Inside the installation frame, there is a filter fiber layer. A cleaning component is provided on the filter fiber layer for cleaning both sides of the filter fiber layer.

[0008] The bubble plate is fixedly connected inside the filtration tank. The air supply assembly includes an air delivery pipe and a bubble generator. The bubble generator is externally powered and fixed on the outer wall of the filtration tank. The air delivery pipe is connected to both sides of the bubble plate and communicates with the bubble outlets. The other end of the air delivery pipe is connected to the bubble generator. By providing a bubble plate inside the filtration tank, the bubble generator transports gas through the air delivery pipe to the bubble plate, and the bubbles move upward through the bubble outlets, so that the bubbles adhere to the suspended particles in the raw water, causing the suspended particles to float to the water surface together with the bubbles, thereby achieving solid-liquid separation and quickly removing suspended substances and oil impurities in the water. Moreover, after the raw water is treated, the water will continue to contact the filtration fiber layer on the installation frame to further treat the raw water, thereby removing most of the suspended substances and impurities in the water, providing a good water source for the subsequent treatment process. At the same time, in the advanced treatment stage, the fiber filtration tank further removes fine particles and microorganisms in the water, improving the water quality of the effluent.

[0009] The collection assembly includes a baffle and a collection box. The baffle is located above the bubble plate and fixedly connected inside the filtration tank. The highest water level inside the filtration tank is below the baffle. When the raw water enters the filtration tank, its water level inside the filtration tank will be below the baffle, so that the floating impurities are below the baffle and are collected by the collection box. The inside of the collection box has fine mesh holes to allow water molecules to pass through. After the bubbles float the impurities, the impurities will float on the water surface and finally enter the collection box. The water molecules pass through the collection box, and the large-particle suspended substances are collected by the collection box, thus achieving the collection of impurities.

[0010] At the top of the side of the baffle away from the bubble plate, there are spaced-apart snap rings. The collection box is located at the bottom of the baffle and below the snap rings, and the inlet position of the collection box is behind the bubble plate. The top of the collection box is provided with spaced-apart plastic buckles. When the plastic buckles are snapped into the snap rings, the collection box is fixed to the bottom of the baffle.

[0011] The number of installation frames is not less than two. There are card slots on the inner bottom surface of the filtration tank, and the installation frames are inserted into the card slots. On the left and right side plates of the filtration tank, there are opposed limit plates, and a limit groove is formed between the two limit plates. The two sides of the installation frame are inserted into the limit groove for sealing. There is a sealing strip between the limit plates and the installation frame, which ensures that after the installation frame is installed, when treating the raw water, water will not leak from between the installation frame and the filtration tank. At the same time, by setting card slots on the filtration tank and inserting the installation frames into the card slots, the stability of the installation frames is ensured.

[0012] The inlet position of the collection box is located behind the bubble plate, so that the impurities attached by the bubbles will flow into the collection box, avoiding the situation that the impurities do not enter the collection box. Moreover, by setting plastic buckles on the top of the collection box, the plastic card slots have a certain ductility and are fixed by being snapped into the snap rings, thus realizing the installation of the collection box and also facilitating disassembly to easily remove the impurities accumulated inside the collection box.

[0013] The cleaning component includes a lifting plate, a brush part and a spray head. The lifting plates are symmetrically located on both sides of the filter fiber layer. The brush part is connected to and fits against the side of the lifting plate close to the filter fiber layer. The spray heads are spaced apart and distributed on the side of the other lifting plate close to the filter fiber layer. The spray heads are provided with water pipes that pass through the lifting plate and extend to the outside of the filter tank. The outer wall of the filter tank is provided with a water tank for the inner wall water pump, and the other end of the water pipe is connected to the water tank. The lifting plate is provided with a power component, and the power component drives the two lifting plates to achieve alternating lifting and lowering.

[0014] The power component includes a power wheel, a power cable, a power shaft and a motor. The power wheels are symmetrically distributed above the installation frame. The power shaft passes through the power wheel and is fixedly connected to it. Both ends of the power shaft are provided with mounting plates connected to the top of the filter tank. The power cable is wound around the power wheel, and its two ends are respectively connected to the lifting plates on both sides of the filter fiber layer. The cleaning component is arranged on both sides of the filter fiber layer. When the filter fiber layer is attached with suspended matter, organic matter and microbial impurities, the power component drives the lifting plate to change its height. Among them, under the rotation of the power wheel, the power cable moves on the power wheel. The two ends of the power cable are respectively connected to the lifting plates. The spray direction of the spray head is similar to the water flow direction, and the water is sprayed on the filter fiber layer in the reverse direction, making the attached impurities more likely to fall off. Moreover, after the spraying is completed, the brush part on the other side will immediately scrape the impurities on the filter fiber layer again. Through the linkage of the two, the impurities on the filter fiber layer are effectively removed, improving the purification treatment effect of the raw water.

[0015] A groove is provided at the top of the lifting plate, and a counterweight plate is arranged in the groove; the counterweight plate is installed in the groove, and the weight of the counterweight plate is greater than that of the lifting plate, so as to drive the lifting plate to move downward in the raw water and avoid the situation that the lifting plate cannot move downward due to excessive buoyancy.

[0016] Two adjacent limiting plates on the same side are provided with vertical mating grooves on the back. The cross-section of the mating groove is T-shaped, and the vertical section of the T-shape faces outward. The two sides of the lifting plate are provided with limiting card strips, and the limiting card strips are movably inserted into the mating grooves to cooperate with each other; the limiting card strips and the mating grooves cooperate with each other, thus limiting the movement stroke of the lifting plate so that it can only move vertically in height, avoiding the situation of shaking during the movement of the lifting plate and ensuring the normal operation of the brush part and the spray head.

[0017] The beneficial effects achieved by the present invention are as follows:

[0018] In the present invention, cleaning components are arranged on both sides of the filter fiber layer. When impurities such as suspended matter, organic matter, and microorganisms adhere to the filter fiber layer, the lifting plate is driven by the power component to change its height. Among them, under the rotation of the power wheel, the power cable moves on the power wheel. Both ends of the power cable are respectively connected to the lifting plate. The spraying direction of the spray head of the spray head is similar to the water flow direction, and water is sprayed on the filter fiber layer in a reverse manner, making the attached impurities more easily fall off. Moreover, after spraying, the brush part on the other side immediately scrapes the impurities on the filter fiber layer again. Through the linkage of the two, the impurities on the filter fiber layer are effectively removed, improving the purification treatment effect of raw water.

[0019] In the present invention, a bubble plate is provided inside the filter tank. The bubble generator transports gas to the bubble plate through the air delivery pipe, and the bubbles move upward through the bubble outlet, so that the bubbles adhere to the suspended particles in the raw water, and the suspended particles float to the water surface together with the bubbles, thereby realizing solid-liquid separation, and quickly removing impurities such as suspended matter and oil in the water. Moreover, after the raw water is treated, the water will continue to contact the filter fiber layer on the installation frame to further treat the raw water, thereby removing most of the suspended matter and impurities in the water, providing a good water source for the subsequent treatment process. At the same time, in the deep treatment stage, the fiber filter tank can further remove the fine particles and microorganisms in the water, improving the water quality of the effluent.

[0020] In the present invention, the inlet position of the collection box is set behind the bubble plate, so that the impurities attached by the bubbles will flow into the collection box, avoiding the situation that the impurities do not enter the collection box. Moreover, by setting plastic buckles on the top of the collection box, the plastic card slots have a certain ductility and can be fixed by being snapped into the snap ring, thereby realizing the installation of the collection box and also facilitating disassembly, and the impurities accumulated inside the collection box can be easily removed.

Detailed implementation manners

[0030] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] The technical solution of the present invention is realized as follows: It includes a filter tank 1. Inside the top surface of the filter tank 1 near the water inlet, there is a bubble plate 2. The bubble plate 2 is provided with evenly distributed bubble outlets 3. A gas supply assembly is provided on the bubble plate 2. Above the bubble plate 2, there is a collection assembly for collecting the floating impurities.

[0032] An installation frame 4 is located on the side of the bubble plate 2 away from the water inlet. Inside the installation frame 4, there is a filter fiber layer 5. A cleaning component is provided on the filter fiber layer 5 for cleaning both sides of the filter fiber layer 5.

[0033] It should be noted that by providing a bubble plate 2 inside the filter tank 1, the bubble generator 7 conveys gas through the air delivery pipe 6 to the bubble plate 2. Through the bubble outlets 3, the bubbles move upward, so that the bubbles adhere to the suspended particles in the raw water, and the suspended particles float to the water surface together with the bubbles, thereby realizing solid-liquid separation and quickly removing impurities such as suspended substances and oils in the water.

[0034] Moreover, after the raw water is treated, the water will continue to contact the filter fiber layer 5 on the installation frame 4 to further treat the raw water, thereby removing most of the suspended solids and impurities in the water and providing a good water source for the subsequent treatment process. At the same time, in the advanced treatment stage, the fiber filter tank can further remove the fine particles and microorganisms in the water and improve the water quality of the effluent.

[0035] In this embodiment, the bubble plate 2 is fixedly connected inside the filter tank 1. The air supply assembly includes an air delivery pipe 6 and a bubble generator 7. The bubble generator 7 is externally powered and fixed on the outer side wall of the filter tank 1. The air delivery pipe 6 is connected to both sides of the bubble plate 2 and communicates with the bubble outlet 3. The other end of the air delivery pipe 6 is connected to the bubble generator 7.

[0036] It should be noted that the bubble generator 7 is externally powered. The bubble generator 7 delivers gas into the bubble plate 2 through the air delivery pipe 6. The bubbles will come out from the bubble outlet 3 and move upward. Thus, when the bubbles burst during the upward movement, they will adsorb impurities, effectively floating the particulate impurities in the raw water, and the impurities will be collected through the subsequent collection assembly.

[0037] In this embodiment, the collection assembly includes a baffle 8 and a collection box 9. The baffle 8 is located above the bubble plate 2 and is fixedly connected inside the filter tank 1. The highest water level inside the filter tank 1 is below the baffle 8.

[0038] It should be noted that when the raw water enters the filter tank 1, its water level inside the filter tank 1 will be below the baffle 8, so that the floating impurities are below the baffle 8 and are collected through the collection box 9. The inside of the collection box 9 has fine mesh holes that allow water molecules to pass through. Thus, after the bubbles float the impurities, the impurities will float on the water surface and finally enter the collection box 9. The water molecules can pass through the collection box 9, but the large particulate suspended solids will be collected by the collection box 9, thereby achieving the collection of impurities.

[0039] In this embodiment, the top of one side of the baffle 8 away from the bubble plate 2 is provided with spaced-apart snap rings 10. The collection box 9 is located at the bottom of the baffle 8 and below the snap rings 10. The inlet position of the collection box 9 is behind the bubble plate 2. The top of the collection box 9 is provided with spaced-apart plastic fasteners 11. When the plastic fasteners 11 are snapped into the snap rings 10, the collection box 9 is fixed to the bottom of the baffle 8.

[0040] It should be noted that the inlet position of the collection box 9 is located behind the bubble plate 2, so that the impurities attached by the bubbles will flow into the collection box 9, avoiding the situation where the impurities do not enter the collection box 9. Moreover, by setting a plastic buckle 11 on the top of the collection box 9, the plastic card slot 12 has a certain ductility and can be fixed by being snapped into the snap ring 10, thus realizing the installation of the collection box 9 and also facilitating disassembly, and the impurities accumulated inside the collection box 9 can be easily removed.

[0041] In this embodiment, the number of installation frames 4 is not less than two. There are card slots 12 on the inner bottom surface of the filtration tank 1, and the installation frames 4 are inserted into the card slots 12. There are position - opposite limiting plates 13 on the left and right side plates of the filtration tank 1. One limiting plate 13 is composed of two limiting plates 13, and a limiting groove 14 is formed between the two limiting plates 13, and both sides of the installation frame 4 are inserted into the limiting groove 14 for sealing.

[0042] It should be noted that there is a sealing strip between the limiting plate 13 and the installation frame 4, so as to ensure that after the installation frame 4 is installed, when treating the raw water, water will not leak from between the installation frame 4 and the filtration tank 1. At the same time, by setting the card slot 12 on the filtration tank 1 and inserting the installation frame 4 into the card slot 12, the stability of the installation frame 4 is ensured.

[0043] In this embodiment, the cleaning component includes a lifting plate 15, a brush part 16 and a spray head 17. The lifting plates 15 are symmetrically located on both sides of the filter fiber layer 5. The brush part 16 is connected to and fits against the side of the lifting plate 15 close to the filter fiber layer 5. The spray heads 17 are distributed at intervals on the side of the other lifting plate 15 close to the filter fiber layer 5. A water delivery pipe 18 passing through the lifting plate 15 and extending to the outside of the filtration tank 1 is provided on the spray head 17. There is a water tank 19 with an inner wall water pump on the outer wall of the filtration tank 1, and the other end of the water delivery pipe 18 is connected to the water tank 19. A power component is provided on the lifting plate 15, and the power component drives the two lifting plates 15 to achieve alternating lifting.

[0044] In this embodiment, the power component includes a power wheel 20, a power cable 21, a power shaft 22 and a motor 23. The power wheels 20 are symmetrically distributed above the installation frame 4. The power shaft 22 passes through the power wheel 20 and is fixedly connected to it. Installation plates 24 connected to the top of the filtration tank 1 are provided at both ends of the power shaft 22. The power cable 21 is wound around the power wheel 20, and its two ends are respectively connected to the lifting plates 15 on both sides of the filter fiber layer 5.

[0045] It should be noted that cleaning components are provided on both sides of the filter fiber layer 5. When the filter fiber layer 5 is attached with impurities such as suspended matter, organic matter, and microorganisms, the lifting plate 15 is driven by the power component to change its height. Among them, under the rotation of the power wheel 20, the power cable 21 moves on the power wheel 20. Both ends of the power cable 21 are respectively connected to the lifting plate 15. The spraying direction of the spray head 17 of the spray head is similar to the water flow direction, and water is sprayed on the filter fiber layer 5 in the reverse direction, making the attached impurities more easily fall off. Moreover, after spraying, the brush part 16 on the other side immediately scrapes the impurities on the filter fiber layer 5 again. Through the linkage of the two, the impurities on the filter fiber layer 5 are effectively removed, improving the purification treatment effect of the raw water.

[0046] In this embodiment, a groove 25 is provided at the top of the lifting plate 15, and a counterweight plate 26 is provided in the groove 25.

[0047] It should be noted that the counterweight plate 26 is installed in the groove 25, and the weight of the counterweight plate 26 is greater than the weight of the lifting plate 15, thereby driving the lifting plate 15 to move downward in the raw water and avoiding the situation where the lifting plate 15 cannot move downward due to excessive buoyancy.

[0048] In this embodiment, two adjacent limiting plates 13 on the same side are provided with vertical mating grooves 27 on the back. The cross-section of the mating groove 27 is "T" shaped, and the vertical section of the "T" shape faces outward. Limiting card strips 28 are provided on both sides of the lifting plate 15, and the limiting card strips 28 are movably inserted into the mating grooves 27 for cooperation.

[0049] It should be noted that the limiting card strips 28 cooperate with the mating grooves 27, thereby limiting the movement stroke of the lifting plate 15 so that it can only move vertically in height, avoiding the situation where the lifting plate 15 shakes during the movement, and ensuring the normal operation of the brush part 16 and the spray head 17.

[0050] The key points and points to be protected by the present invention are:

[0051] 1. By spraying water on the filter fiber layer in the reverse direction, the attached impurities can fall off more easily. Moreover, after spraying, the brush part on the other side immediately scrapes the impurities on the filter fiber layer again. Through the linkage of the two, the impurities on the filter fiber layer are effectively removed, improving the purification treatment effect of the raw water.

[0052] 2. In the advanced treatment stage, the fiber filter tank can further remove fine particles and microorganisms in the water, improving the water quality of the effluent.

[0053] 3. The installation of the collection box is realized, and it is also convenient for disassembly, and the impurities accumulated inside the collection box can be easily removed.

[0054] When the raw water needs to be treated, the raw water is first introduced into the water inlet of the filter tank 1 so that it enters the filter tank 1. At this time, the bubble generator 7 is started, and the bubble generator 7 will transport the gas to the gas pipe 6 and enter the bubble plate 2. The top of the bubble plate 2 has evenly distributed bubble outlets 3, so that bubbles will continuously emerge and move upward from the bottom of the filter tank 1. The bubbles break in the process of rising and adhere to the impurities in the raw water, driving the impurities to move upward. Finally, the impurities will float on the surface of the raw water and flow to the bottom of the baffle 8 driven by the water flow. A collection box 9 is installed at the bottom of the baffle 8 to collect the impurities.

[0055] After the first step of treatment, the raw water will contact the filter fiber layer 5 on the mounting frame 4, and the filter fiber layer 5 will further process the raw water, blocking more fine impurities, and further processing the water. During the water treatment process of the filter fiber layer 5, impurities will also adhere to the surface of the filter fiber layer 5. When there are more impurities attached, the cleaning component starts to work, and the motor 23 drives the power shaft 22 to rotate, thereby starting the connected power wheel 20 to rotate. The power wheel 20 is wound with a power cable 21, and the power cable 21 is The two ends are respectively connected to the lifting plates 15 on both sides of the filter fiber layer 5. In the initial state, the lifting plates 15 on both sides are one high and one low. The lifting plates 15 are respectively provided with a spray head 17 and a brush part 16. The water pump in the water tank 19 delivers water to the spray head 17 through the water pipe 18. The water will be sprayed from the spray head 17 to the filter fiber layer 5. The spray direction of the spray head 17 is opposite to the water flow direction in the filter tank 1, so as to flush the filter fiber layer 5 from the back, so that impurities can be better dropped from the filter fiber layer 5.

[0056] When the power cable 21 drives the lifting plate 15 on the spray head 17 to move upward, the lifting plate 15 on the brush part 16 on the other side will move downward to brush the place sprayed by the spray head 17. When the spray head 17 descends, it will drive the brush part 16 to move upward. Therefore, during the back and forth movement, the spray head 17 and the brush part 16 will cooperate with each other to remove impurities on the filter fiber layer 5, thereby treating the raw water and cleaning the filter pool 1 at the same time.

[0057] The embodiments of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.

The self-cleaning gas floating fiber filter according to claim 7, characterized in that: A groove is provided on the top of the lifting plate, and a counterweight plate is provided in the groove; the counterweight plate is installed in the groove, and the weight of the counterweight plate is greater than the weight of the lifting plate, thereby driving the lifting plate to move downward in the raw water, avoiding the situation where the lifting plate cannot move downward due to excessive buoyancy.

10. The self-cleaning gas floating fiber filter according to claim 7, characterized in that: Two adjacent limit plates on the same side are provided with vertical matching grooves on the back side. The cross-section of the matching groove is T-shaped, and the vertical section of the T-shape faces outward. Limit card strips are provided on both sides of the lifting plate, and the limit card strips are movably inserted into the matching grooves to cooperate with each other; the limit card strips and the matching grooves cooperate with each other, thereby limiting the movement stroke of the lifting plate so that it can only achieve vertical height movement, avoiding shaking of the lifting plate during movement, and ensuring the normal operation of the brush part and the sprinkler head.
