Description

Technical Field

[0001] This invention relates to the field of water filtration equipment technology, specifically to a water source filtration and algae removal device. Background Technology

[0002] Water conservancy projects typically utilize water pipelines for water delivery. To reduce the likelihood of debris entering and clogging these pipelines, filters are usually installed inside. However, water sources generally contain significant amounts of algae. When these algae enter the pipeline with the water flow, they adhere to the surface of the filter, causing it to stick to the filter. This slows down the flow rate and can even completely clog the filter, severely impacting the pipeline's water delivery efficiency. Summary of the Invention

[0003] The present invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of the present invention propose a water source filtration and algae removal device with high water conveyance efficiency.

[0004] The water source filtration and algae removal device of this invention includes a main pipe, a filter plate, a mounting frame, and a return spring. The main pipe has an inlet and an outlet. The inlet is used to communicate with a water source, and the outlet is used to communicate with a water supply pipe. A sliding groove extending along the axial direction of the main pipe is provided on the inner wall of the main pipe.

[0005] The filter plate and the mounting bracket are spaced apart along the axial direction of the main pipe inside the main pipe. The filter plate is located near the inlet of the main pipe. The filter plate includes a plate body and a sliding part. The plate body has a plurality of spaced filter holes. The sliding part is slidably engaged with the sliding groove along the axial direction of the main pipe. The mounting bracket has a plurality of pins on one side near the filter plate. The plurality of pins correspond one-to-one with the plurality of filter holes. The pins extend along the axial direction of the main pipe and are used to pass through the filter holes to push out algae derivatives that block the filter holes.

[0006] The return spring is disposed inside the main pipe, and the return spring is used to provide the filter plate with an elastic force along the axial direction of the main pipe away from the ejector pin.

[0007] In some embodiments, the plate body has a first through hole extending along its thickness direction, the mounting bracket has a first push rod extending axially along the main pipe, one end of the first push rod passes through the first through hole, the outer circumferential surface of the first push rod has a first sliding groove spirally arranged, the plate body has a first sleeve rotatably provided on the side away from the ejector pin, the first sleeve is sleeved on the first push rod, the inner wall of the first sleeve has a first sliding rod extending radially along the first sleeve, at least a portion of the first sliding rod is placed in the first sliding groove and slides in cooperation with the first sliding groove, so that when the first push rod moves axially relative to the first sleeve in the main pipe, it can drive the first sleeve to rotate, the outer circumferential surface of the first sleeve has a scraper extending radially along the first sleeve, the scraper is used to scrape off algae derivatives on the filter plate.

[0008] In some embodiments, the length of the ejector pin is the same as the depth of the filter hole.

[0009] In some embodiments, the diameter of the ejector pin is d, and the inner diameter of the filter hole is D, where 1 / 3D≤d≤2 / 3D.

[0010] In some embodiments, the number of scrapers is multiple, and the multiple scrapers are arranged at circumferential intervals along the first sleeve. Each scraper has a first cutting edge and a second cutting edge arranged opposite to each other in its width direction.

[0011] In some embodiments, a drain outlet is provided at the bottom of the main pipe, and a sludge storage tank communicating with the drain outlet is provided on the main pipe. An opening and closing cover for sealing the drain outlet is provided on the side of the filter plate near the pin. When the filter plate moves in a direction closer to the pin, the opening and closing cover opens the drain outlet, so that the scraper scrapes the algae derivatives on the filter plate into the sludge storage tank.

[0012] In some embodiments, the main pipe has a first water passage hole and a second water passage hole on the pipe wall on both sides of the filter plate. The first water passage hole is located near the water inlet. A branch pipe is provided between the first water passage hole and the second water passage hole. A sealing valve plate is provided on the second water passage hole. The sealing valve plate is rotatably connected to the main pipe. A control component is provided between the filter plate and the sealing valve plate.

[0013] When the filter plate moves axially toward the pin along the main pipe, the control component controls the sealing valve plate to rotate to open the second water passage. When the filter plate moves axially away from the pin along the main pipe, the control component controls the sealing valve plate to rotate to close the second water passage.

[0014] In some embodiments, the control component includes a rotating shaft and a second sleeve. The extending direction of the rotating shaft is parallel to the extending direction of the main pipe and is rotatably connected to the pipe wall of the main pipe. One end of the rotating shaft is connected to the sealing valve plate, and a second sliding groove is provided on the outer circumferential surface of the other end of the rotating shaft.

[0015] The second sleeve is coaxially arranged with the rotating shaft. One end of the second sleeve is connected to the filter plate, and the other end of the second sleeve is sleeved on the rotating shaft. A second sliding rod is provided on the inner wall of the second sleeve, extending radially along the second sleeve. The second sliding rod is placed in the second sliding groove and slides in cooperation with the second sliding groove, so that when the second sleeve moves relative to the rotating shaft in the axial direction of the main pipe, it can drive the rotating shaft to rotate.

[0016] In some embodiments, the main pipe has a second through hole on its wall. The extension direction of the second through hole is parallel to the axial direction of the main pipe and communicates with the sliding groove and the second water passage hole respectively. At least a portion of the second sleeve is disposed in the sliding groove and connected to the sliding part of the filter plate. At least a portion of the rotating shaft is disposed in the second through hole and rotatably engages with the second through hole.

[0017] In some embodiments, the return spring is sleeved in the sliding groove and on the second sleeve, with its two ends abutting against the sliding part and the sidewall of the sliding groove, respectively.

[0018] In use, the water source filtration and algae removal device of this invention connects the inlet of the main pipeline to the water source and the outlet of the main pipeline to the water supply pipeline. When algae in the water source clog the filter holes, preventing water from flowing normally through them, a pressure difference is generated upstream and downstream of the filter holes. Under the force of the upstream water pressure, the filter plate slides along the axial direction of the main pipeline towards the push pin, allowing the push pin to enter the filter holes and push away the algae blocking the filter holes or adhering to the filter plate surface, keeping the filter plate unobstructed. Once the filter plate is unobstructed, the pressure difference between the upstream and downstream of the filter holes decreases, the filter plate resets under the elastic force of the return spring, and the push pin separates from the filter holes, ensuring that water can flow normally through them. Thus, the water source filtration and algae removal device of this invention can effectively filter and remove algae from the water source, ensuring water quality cleanliness and safety, preventing algae in the water source from reducing the water flow rate of the main pipeline due to filter plate clogging, and greatly improving water supply efficiency.

[0033] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0034] like Figures 1 to 12 As shown, the water source filtration and algae removal device 100 of this embodiment includes a main pipe 1, a filter plate 2, a mounting bracket 3, and a return spring 5. The main pipe 1 has an inlet 101 and an outlet 102. The inlet 101 is used to communicate with a water source, and the outlet 102 is used to communicate with a water supply pipe. A sliding groove 103 extending axially along the main pipe 1 is provided on the inner wall of the main pipe 1.

[0035] The filter plate 2 and the mounting bracket 3 are spaced apart in the main pipe 1 along the axial direction. The filter plate 2 is located near the water inlet 101 of the main pipe 1. The filter plate 2 includes a plate body 201 and a sliding part 202. The plate body 201 has a plurality of spaced filter holes 2011. The sliding part 202 is slidably engaged with the sliding groove 103 along the axial direction of the main pipe 1.

[0036] The mounting bracket 3 has multiple ejector pins 4 on one side near the filter plate 2. Each ejector pin 4 corresponds to a filter hole 2011. The ejector pins 4 extend axially along the main pipe 1 and are used to pass through the filter holes 2011 to push out algae derivatives that are clogging the filter holes 2011. A return spring 5 is provided inside the main pipe 1. The return spring 5 is used to provide the filter plate 2 with an elastic force along the axial direction of the main pipe 1 away from the ejector pins 4.

[0037] In use, the water source filtration and algae removal device 100 of this embodiment connects the inlet 101 of the main pipe 1 to the water source and the outlet 102 of the main pipe 1 to the water supply pipe. When algae in the water source clog the filter hole 2011, preventing water from flowing normally through the filter hole 2011, a pressure difference is generated upstream and downstream of the filter hole 2011. Under the force of the upstream water pressure, the filter plate 2 slides along the axial direction of the main pipe 1 towards the push pin 4, allowing the push pin 4 to enter the filter hole 2011 and push open the algae that are blocking the filter hole 2011 or adhering to the surface of the filter plate 2, keeping the filter plate 2 unobstructed. When the filter plate 2 is unobstructed, the water pressure difference upstream and downstream of the filter hole 2011 decreases, and the filter plate 2 resets under the elastic force of the return spring 5. At the same time, the push pin 4 separates from the filter hole 2011, ensuring that the water can flow normally through the filter hole 2011.

[0038] Therefore, the water source filtration and algae removal device 100 of this embodiment of the invention can effectively filter and remove algae from the water source, ensuring the cleanliness and safety of the water quality, preventing algae derivatives in the water source from clogging the filter plate 2 and reducing the water flow of the main pipeline 1, and greatly improving the water conveyance efficiency.

[0039] In some embodiments, the plate body 201 is provided with a first through hole (not shown in the figure) extending in the thickness direction, and the mounting bracket 3 is provided with a first push rod 6 extending axially along the main pipe 1. One end of the first push rod 6 passes through the first through hole, and a first groove 601 spirally arranged on the outer peripheral surface of the first push rod 6.

[0040] A first sleeve 7 is rotatably provided on the side of the plate body 201 away from the ejector pin 4. The first sleeve 7 is sleeved on the first push rod 6. A first slide rod 8 extending radially along the inner wall of the first sleeve 7 is provided. At least a portion of the first slide rod 8 is placed in and slides in the first slide groove 601, so that when the first push rod 6 moves axially relative to the first sleeve 7 in the main pipe 1, it can drive the first sleeve 7 to rotate. A scraper 9 extending radially along the outer circumference of the first sleeve 7 is provided. The scraper 9 is used to scrape off algae derivatives on the filter plate 2.

[0041] Specifically, such as Figure 8 , Figure 9 and Figure 11 As shown, when the filter plate 2 moves axially towards the ejector pin 4 in the main pipe 1, the first push rod 6 can move relative to the first sleeve 7. Under the action of the first sliding groove 601 and the first sliding rod 8, the first push rod 6 can drive the first sleeve 7 to rotate. While the first sleeve 7 is rotating, it can drive the scraper 9 to rotate. The rotation of the scraper 9 can not only scrape off the algae derivatives attached to the filter plate 2, but also push the ejector pin 4 out of the filter hole 2011 to scrape off the algae derivatives, thereby improving the cleaning efficiency of the water source filtration and algae removal device 100 of this embodiment of the invention.

[0042] Optionally, the length of the ejector pin 4 is the same as the depth of the filter hole 2011. If the length of the ejector pin 4 is set too long, for example, greater than the depth of the filter hole 2011, there is a risk of interference and collision between the ejector pin 4 and the scraper 9 as it passes through the filter hole 2011. If the length of the ejector pin 4 is set too short, for example, less than the depth of the filter hole 2011, algae derivatives inside the filter hole 2011 may not be completely ejected, resulting in incomplete cleaning. Therefore, by setting the length of the ejector pin 4 to be the same as the depth of the filter hole 2011, both the operational safety of the ejector pin 4 and its cleaning reliability can be effectively guaranteed.

[0043] Optionally, the diameter of the ejector pin 4 is d, and the inner diameter of the filter hole 2011 is D, where 1 / 3D ≤ d ≤ 2 / 3D. For example, the diameter of the ejector pin 4 is 1 / 3, 1 / 2, or 2 / 3 of the diameter of the filter hole 2011. By rationally designing the diameter of the ejector pin 4, it has sufficient force to effectively clean the algae derivatives in the filter hole 2011 when pushing them, without being too large and damaging the filter hole 2011 or the filter plate 2. This helps improve the cleaning effect while reducing damage to the filtration equipment.

[0044] In some embodiments, there are multiple scrapers 9, which are spaced apart circumferentially along the first sleeve 7. Each scraper 9 has a first cutting edge 901 and a second cutting edge 902 that are arranged opposite to each other in its width direction.

[0045] For example, such as Figure 6 As shown, when the filter plate 2 moves axially towards the ejector pin 4 in the main pipe 1, the first push rod 6 drives the first sleeve 7 to rotate clockwise, which in turn drives the scraper 9 to rotate clockwise. When the filter plate 2 is reset by the return spring 5, that is, when the filter plate 2 moves axially away from the ejector pin 4 in the main pipe 1, the first push rod 6 drives the first sleeve 7 to rotate counterclockwise, which in turn drives the scraper 9 to rotate counterclockwise. Since the scraper 9 has a first blade 901 and a second blade 902 arranged opposite each other along its width direction, the scraper 9 scrapes off algae derivatives on the filter plate 2 during both clockwise and counterclockwise rotations, further improving the cleaning effect of the water source filtration and algae removal device 100 of this embodiment of the invention.

[0046] In some embodiments, a drain outlet 107 is provided at the bottom of the main pipe 1, and a sludge storage tank 10 communicating with the drain outlet 107 is provided on the main pipe 1. An opening and closing cover 11 for sealing the drain outlet 107 is provided on the side of the filter plate 2 near the ejector pin 4. When the filter plate 2 moves in a direction closer to the ejector pin 4, the opening and closing cover 11 opens the drain outlet 107 so that the scraper 9 scrapes the algae derivatives on the filter plate 2 into the sludge storage tank 10.

[0047] For example, such as Figure 2 , Figure 3 and Figure 8As shown, when the filter plate 2 moves axially towards the ejector pin 4 in the main pipe 1, the filter plate 2 will cause the opening and closing cover 11 to move towards the ejector pin 4. The opening and closing cover 11 opens the drain port 107, and the scraper 9 scrapes off the algae derivatives on the filter plate 2. Under the action of gravity, the algae will enter the sludge storage tank 10 through the drain port 107 for storage. When the filter plate 2 returns to its original position axially away from the ejector pin 4 in the main pipe 1, the filter plate 2 will cause the opening and closing cover 11 to move away from the ejector pin 4. The opening and closing cover 11 closes the drain port 107 to prevent the algae derivatives stored in the sludge storage tank 10 from returning to the main pipe 1 and clogging the filter plate 2. It should be noted that the algae derivatives in the sludge storage tank 10 can be cleaned periodically to ensure that there is sufficient storage space in the sludge storage tank 10 for storing the scraped algae derivatives.

[0048] In some embodiments, the main pipe 1 has a first water passage hole 104 and a second water passage hole 105 on the pipe walls on both sides of the filter plate 2. The first water passage hole 104 is located near the water inlet 101, and a branch pipe 12 is provided between the first water passage hole 104 and the second water passage hole 105. A sealing valve plate 13 is provided on the second water passage hole 105, and the sealing valve plate 13 is rotatably connected to the main pipe 1. A control component is provided between the filter plate 2 and the sealing valve plate 13.

[0049] When the filter plate 2 moves axially along the main pipe 1 towards the pin 4, the control component controls the sealing valve plate 13 to rotate, thereby opening the second water passage 105. When the filter plate 2 moves axially along the main pipe 1 away from the pin 4, the control component controls the sealing valve plate 13 to rotate, thereby closing the second water passage 105.

[0050] Specifically, such as Figures 2 to 8 As shown, when filter plate 2 moves axially towards the pin 4 in the main pipe 1, it indicates that filter plate 2 has been blocked by algae derivatives, resulting in a pressure difference between the upstream and downstream sides of filter plate 2. When the pressure difference exceeds the elastic force of the return spring 5, filter plate 2 will overcome the elastic force of the return spring 5 and move towards the pin 4. At the same time, due to the blockage of filter plate 2 by algae derivatives, the water flow rate in the main pipe 1 decreases. During the process of filter plate 2 moving axially towards the pin 4 in the main pipe 1, the control component will control the sealing valve plate 13 to rotate, thereby opening the second water passage 105, allowing some water upstream of filter plate 2 to flow downstream of filter plate 2 through branch pipe 12, so as to effectively ensure the water flow rate and water delivery efficiency of the main pipe 1.

[0051] Of course, the opening angle of the sealing valve plate 13 can be adjusted according to the displacement of the filter plate 2, so that the reduced water flow in the main pipeline 1 can be compensated by the branch pipeline 12, so as to effectively ensure the water conveyance efficiency of the main pipeline 1.

[0052] In some embodiments, the control component includes a rotating shaft 14 and a second sleeve 15. The rotating shaft 14 extends parallel to the extension direction of the main pipe 1 and is rotatably connected to the pipe wall of the main pipe 1. One end of the rotating shaft 14 is connected to a sealing valve plate 13, and a second groove 1401 spirally arranged is provided on the outer circumferential surface of the other end of the rotating shaft 14.

[0053] The second sleeve 15 is coaxially arranged with the rotating shaft 14. One end of the second sleeve 15 is connected to the filter plate 2, and the other end of the second sleeve 15 is sleeved on the rotating shaft 14. A second slide rod 16 extending radially along the inner wall of the second sleeve 15 is provided. The second slide rod 16 is placed in the second slide groove 1401 and slides in cooperation with the second slide groove 1401, so that when the second sleeve 15 moves axially relative to the rotating shaft 14 in the main pipe 1, it can drive the rotating shaft 14 to rotate.

[0054] For example, such as Figure 7 , Figure 10 and Figure 12 As shown, when the filter plate 2 moves axially in the main pipe 1, it can drive the second sleeve 15 to move axially in the main pipe 1. When the second sleeve 15 moves axially in the main pipe 1 relative to the rotating shaft 14, it can drive the rotating shaft 14 to rotate, which can effectively control the rotation of the sealing valve plate 13 and realize the opening and closing of the second water passage 105. The combination of the rotating shaft 14 and the second sleeve 15 can realize the rotation control of the sealing valve plate 13 and ensure that the opening and closing process of the second water passage 105 is smooth and accurate.

[0055] The sliding fit between the second sliding groove 1401 spirally arranged around the rotating shaft 14 and the second sliding rod 16 on the second sleeve 15 helps to realize the relative movement between the rotating shaft 14 and the second sleeve 15, thereby ensuring the accurate rotation of the sealing valve plate 13. This structural design is simple and reliable. Through the dynamic adjustment of the control components, the flow rate of water through the second water passage 105 can be effectively controlled, making the operation of the filtration system more stable and efficient.

[0056] In some embodiments, the main pipe 1 has a second through hole 106 on its wall. The extension direction of the second through hole 106 is parallel to the axial direction of the main pipe 1 and is connected to the sliding groove 103 and the second water passage hole 105 respectively. At least a portion of the second sleeve 15 is disposed in the sliding groove 103 and connected to the sliding part 202 of the filter plate 2. At least a portion of the rotating shaft 14 is disposed in the second through hole 106 and is rotatably engaged with the second through hole 106.

[0057] For example, such as Figure 8 and Figure 10As shown, a portion of the second sleeve 15 is disposed within the sliding groove 103 and connected to the sliding part 202 of the filter plate 2, thus saving space occupied by the main pipe 1. A portion of the rotating shaft 14 is disposed within the second through hole 106 and rotatably engages with the second through hole 106, thereby facilitating the installation and rotation of the rotating shaft 14, which in turn facilitates the control of the rotation of the sealing valve plate 13 and the opening and closing of the second water passage 105.

[0058] Optionally, the return spring 5 is sleeved in the sliding groove 103 and on the second sleeve 15, with the two ends of the return spring 5 abutting against the sliding part 202 and the groove sidewall of the sliding groove 103, respectively.

[0059] For example, such as Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the function of the return spring 5 is to provide a certain preload to ensure the stability of the movement of the filter plate 1, thereby ensuring the stability of the sliding fit between the filter plate 2 and the main pipe 1. Simultaneously, when the filter plate 2 needs to move, the return spring 5 can provide a certain thrust to allow the filter plate 2 to move smoothly. This design improves the stability and reliability of the filtration operation.
