Description

Technical Field

[0001] This utility model relates to the field of rainwater treatment technology, and more specifically, to a rainwater treatment device. Background Technology

[0002] Rainwater treatment refers to the process of treating and purifying recycled rainwater through a series of technological means to meet certain water quality standards for reuse. This process helps conserve water resources, reduces pressure on urban drainage systems, and provides a sustainable water source for non-potable uses (such as irrigation, toilet flushing, and landscaping), playing a vital role in our modern lives and future development.

[0003] Currently, rainwater harvesting and treatment typically involves installing filters to prevent large debris from entering the rainwater. However, during use, debris and other contaminants accumulate on the filters, clogging the mesh and significantly reducing the efficiency of rainwater collection and treatment. This greatly affects the treatment effect of the treatment tank, requiring frequent cleaning by staff, which is labor-intensive, time-consuming, and ineffective.

[0004] Therefore, it is necessary to provide a rainwater treatment device to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a rainwater treatment device to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rainwater treatment device includes a treatment tank and an inlet hopper disposed thereon, wherein the treatment tank has a collection chamber inside, and further includes:

[0008] A filter plate is flexibly disposed within the collection chamber, and the filter plate has multiple filter holes.

[0009] The filter has multiple plug rods that are adapted to the filter holes, and the collection chamber is equipped with a lifting mechanism for moving the plug rods up and down.

[0010] The pusher plate contacts the upper surface of the filter plate, and the processing box is provided with a first telescopic member for driving the pusher plate to move horizontally.

[0011] A collection box is provided on the processing box, and the collection box has a material cavity that communicates with the collection chamber.

[0012] Furthermore, the sidewall of the collection chamber is provided with multiple sliding grooves, and a slider is slidably connected to the inner wall of the sliding groove. The outer end of the slider is connected to the filter plate, and a first elastic element is provided between the slider and the bottom wall of the sliding groove.

[0013] Furthermore, the pusher plate includes an outer plate and a lower scraper. The outer plate has an inner groove, and the lower scraper is slidably connected in the inner groove. A second elastic member is provided between the upper end of the lower scraper and the upper wall of the inner groove.

[0014] Furthermore, the lifting mechanism includes:

[0015] The second telescopic component is provided on the inner wall of the collection cavity and there are multiple of them. The telescopic end of the second telescopic component is provided with a connecting frame, and the multiple plug rods are all provided on the connecting frame.

[0016] Furthermore, the inner wall of the material cavity is provided with an inner groove, a sliding rod is provided in the inner groove, a moving block is slidably connected to the sliding rod, a third elastic element is provided between the moving block and the inner wall of the inner groove, a baffle is connected to the lower end of the sliding rod, and a stop rod is provided on the outer plate.

[0017] Furthermore, a trigger rod and a lower support plate are movably passed through the outer wall of the processing box. The lower support plate is located below the filter plate. One end of the trigger rod and the lower support plate are connected to a connecting plate. A fourth elastic element is provided between the connecting plate and the outer wall of the processing box.

[0018] Furthermore, the inside of the collection chamber is also provided with a fine filter screen, which is located below the filter plate.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. In this solution, when some debris accumulates on the filter plate, the filter plate will gradually become heavier and move downwards. At this time, the lifting mechanism will drive the unblocking rod to move upwards. The unblocking rod will pass through the filter hole and squeeze out the debris in the filter hole, thus realizing the unblocking effect of the filter hole. This can avoid the filter hole from becoming clogged, greatly ensure the filtration effect of the filter plate, and thus improve the efficiency and quality of rainwater recycling and treatment.

[0021] 2. In this solution, the first telescopic component will drive the pusher plate to move horizontally, pushing the debris accumulated on the filter plate into the material cavity of the collection box. This avoids the accumulation of debris on the filter plate and further prevents the filter plate and the treatment box from being affected by the accumulation of debris. It can significantly improve the treatment efficiency of rainwater, extend the service life of the filter plate, greatly reduce the number of times the staff cleans it, save a lot of labor and time, save time and effort, and has good effect. It can be widely used.

[0022] 3. In this solution, the outer plate of the pusher plate is always in contact with the upper surface of the filter plate. When there are many impurities on the filter plate, causing the filter plate to descend, the second elastic element will drive the lower scraper to move and maintain contact with the filter plate. Thus, when the first telescopic element drives the pusher plate to move, the lower scraper can always contact the filter plate and push away the impurities on its surface, which is highly flexible.

[0023] 4. In this solution, when the first telescopic component moves the pusher plate, it will move the abutment rod. After the abutment rod contacts the baffle, it will push the baffle to the right. The debris pushed away by the outer sleeve plate and the lower scraper will enter the material cavity. When the first telescopic component moves the pusher plate back to its original position, the baffle will return to its initial position and block the opening between the filter plate and the material cavity, which can effectively prevent rainwater from entering the material cavity of the collection box directly without treatment.

[0034] 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.

[0035] Please see Figure 1-8 A rainwater treatment device includes a treatment tank 1 and an inlet hopper 2 disposed thereon. The treatment tank 1 has a collection chamber 3 inside. It also includes: a filter plate 4, which is elastically disposed in the collection chamber 3 and has multiple filter holes 5; a plug rod 6, which has multiple plug rods and is adapted to the filter holes 5. The collection chamber 3 is provided with a lifting mechanism 7 for driving the plug rod 6 to move up and down; a pusher plate 8, which is in contact with the upper end surface of the filter plate 4. The treatment tank 1 is provided with a first telescopic member 9 for driving the pusher plate 8 to move horizontally; and a collection box 10, which is disposed on the treatment tank 1 and has a material cavity 11 that communicates with the collection chamber 3. The first telescopic member 9 in this application is an electric telescopic rod. The side wall of the collection chamber 3 is provided with multiple sliding grooves 12. A slider 13 is slidably connected to the inner wall of the sliding groove 12. The outer end of the slider 13 is connected to the filter plate 4. A first elastic element 14 is provided between the slider 13 and the bottom wall of the sliding groove 12. The first elastic element 14 in this application can be a spring or a damper. A displacement sensor is installed in the processing box 1 to monitor the up and down position of the filter plate 4.

[0036] In use, the collected rainwater is introduced into the treatment tank 1 through the inlet hopper 2. The rainwater enters the collection chamber 3, passes through the filter holes 5 of the filter plate 4, and falls to the lower side of the treatment tank 1. The filter plate 4 can block and filter impurities in the rainwater and impurities falling from the inlet hopper 2. After a period of use, some impurities accumulate on the filter plate 4, and the collection effect of the filter plate 4 will deteriorate. At this time, the filter plate 4 will gradually become heavier, which will drive the slider 13 to move along the slide groove 12 and compress the first elastic element 14. After the displacement sensor detects the movement of the filter plate 4, it will activate the lifting mechanism 7. The lifting mechanism 7 will drive the unblocking rod 6 to move upward. The unblocking rod 6 will pass through the filter hole 5, thereby squeezing out the impurities in the filter hole 5, thus realizing the unblocking effect of the filter hole 5. This can prevent the filter hole 5 of the filter plate 4 from becoming blocked during use, greatly ensuring the filtration effect of the filter plate 4, and thus improving the efficiency and quality of rainwater recycling and treatment. The lifting mechanism 7 moves the plug rod 6 upward to penetrate the filter hole 5 and then descends back to the initial position. It can move up and down repeatedly multiple times before stopping and waiting for the next operation.

[0037] After a period of use, the first telescopic component 9 will activate and drive the pusher plate 8 to move. The pusher plate 8 will move horizontally along the filter plate 4, thereby pushing away the debris accumulated on the filter plate 4 and finally pushing the debris into the material cavity 11 of the collection box 10. The material cavity 11 temporarily collects the debris, thus avoiding the accumulation of debris on the filter plate 4. This further prevents the accumulation of debris from affecting the filtration of the filter plate 4 and the treatment effect of the treatment box 1. It can significantly improve the treatment efficiency of rainwater, extend the service life of the filter plate 4, greatly reduce the number of times the staff clean it, save a lot of labor and time, save time and effort, and has good effect. It can be widely used.

[0038] A door 27 is installed on the outer wall of the processing box 1, and a cleaning door 28 is installed on the outer wall of the collection box 10. The interior of the processing box 1 can be maintained and cleaned by opening the door 27; the debris in the collection box 10 can be removed by opening the cleaning door 28. The cleaning operation is simple and convenient for continuous use.

[0039] In this embodiment, preferably, please refer to [reference needed]. Figure 2-3 and Figure 5-8The pusher plate 8 includes an outer plate 81 and a lower scraper 82. The outer plate 81 has an inner groove 15. The lower scraper 82 is slidably connected in the inner groove 15. A second elastic element 16 is provided between the upper end of the lower scraper 82 and the upper wall of the inner groove 15. The second elastic element 16 in this application adopts a combination of spring and damper. The outer plate 81 of the pusher plate 8 is always in contact with the upper surface of the filter plate 4. The elastic force of the first elastic member 14 is greater than that of the second elastic member 16. When the filter plate 4 is in the initial state, the second elastic member 16 is in a compressed state. When there are many impurities on the filter plate 4, causing the filter plate 4 to descend, the second elastic member 16 will drive the lower scraper 82 to move along the inner groove 15. At this time, the lower scraper 82 will descend and remain in contact with the filter plate 4. Thus, when the first telescopic member 9 drives the pusher plate 8 to move, the lower scraper 82 can always contact the filter plate 4 and push away the impurities on its surface. It is highly flexible, meets the usage requirements, and has a good usage effect.

[0040] In this embodiment, preferably, please refer to [reference needed]. Figure 2-3 and Figure 5-6 The lifting mechanism 7 includes: a second telescopic member 71, which is disposed on the inner wall of the collecting cavity 3 and has multiple members; the telescopic end of the second telescopic member 71 is provided with a connecting frame 72, and multiple plug rods 6 are disposed on the connecting frame 72. The second telescopic member 71 in this application is an electric telescopic rod, and a displacement sensor is electrically connected to the second telescopic member 71. After the second telescopic member 71 is activated, it will drive the connecting frame 72 to move up and down, thereby driving the plug rods 6 to move up and down.

[0041] In this embodiment, preferably, please refer to [reference needed]. Figure 2 and Figure 4-6 The inner wall of the material cavity 11 has an inner groove, in which a slide rod 17 is installed. A moving block 18 is slidably connected to the slide rod 17. A third elastic element 19 is provided between the moving block 18 and the inner wall of the inner groove. A baffle 20 is connected to the lower end of the slide rod 17. A stop rod 21 is provided on the outer sleeve plate 81. The third elastic element 19 in this application is a spring or other elastic device. When the first telescopic member 9 drives the pusher plate 8 to move, the outer sleeve plate 81 will drive the stop rod 21 to move, so as to... Figure 6For example, when the abutment rod 21 moves to the right to the position of the baffle 20, it will push the baffle 20 to the right. The baffle 20 will then drive the moving block 18 to move along the sliding rod 17 and compress the third elastic member 19. After the baffle 20 moves to the right, the material cavity 11 is connected to the upper part of the filter plate 4. The debris pushed away by the outer sleeve plate 81 and the lower scraper 82 will enter the material cavity 11. When the first telescopic member 9 drives the pusher plate 8 to move to the left and return to its original position, the abutment rod 21 will also gradually move to the left and no longer squeeze the baffle 20. The rebound force of the third elastic member 19 will drive the baffle 20 to move to the left. The baffle 20 will return to its initial position and block the opening between the filter plate 4 and the material cavity 11. This can effectively prevent rainwater from entering the material cavity 11 of the collection box 10 directly without treatment. The collection box 10 is provided with multiple water outlets so that some of the rainwater entering the material cavity 11 can flow out, thereby increasing the collection capacity of debris.

[0042] In this embodiment, preferably, please refer to [reference needed]. Figure 1-2 and Figure 5-7 A trigger rod 22 and a lower support plate 23 are movably connected through the outer wall of the treatment box 1. The lower support plate 23 is located below the filter plate 4. One end of the trigger rod 22 and the lower support plate 23 are connected to a connecting plate 24. A fourth elastic element 25 is provided between the connecting plate 24 and the outer wall of the treatment box 1. In this application, the fourth elastic element 25 can be a spring. Figure 6 Taking the state shown as an example, when the pusher plate 8 is in the leftmost initial position, the trigger rod 22 is squeezed by the pusher plate 8, and the fourth elastic element 25 is in a stretched state. When the first telescopic element 9 drives the pusher plate 8 to move to the right, the trigger rod 22 is no longer compressed, and the fourth elastic element 25 drives the lower support plate 23 to move to the right. When the filter plate 4 is still above the lower support plate 23, the lower support plate 23 will move to the right below the filter plate 4. This avoids the filter plate 4 from falling when the pusher plate 8 moves to push the material, thus better pushing away the debris on the filter plate 4, resulting in good performance and improved cleaning performance.

[0043] In this embodiment, preferably, please refer to [reference needed]. Figure 2 and Figure 6 The collection chamber 3 is also equipped with a fine filter screen 26, which is located below the filter plate 4. Rainwater falling from the filter plate 4 will be filtered again by the fine filter screen 26, which can filter out some small impurities in the rainwater, thereby improving the subsequent utilization of rainwater. The fine filter screen 26 can be cleaned or replaced by opening the box door 27, making it highly practical.
