Description

Technical Field

[0001] This application relates to the technical field of river water treatment, and specifically relates to a sedimentation and filtration system for turbid river water. Background Art

[0002] River scenery is not only a common landscape form, but also an important ecological corridor and recreation resource, with extremely high value in environmental protection and tourism development. However, due to the variability of river scenery, the protection of river scenery has many characteristics and difficulties of its own. Through the analysis of typical cases, think about the protection of river scenery from aspects such as nature understanding, regional coordination, tourism mode, ecological water replenishment, river channel landscape, shoreline control, and institutional innovation. The history of human utilization of rivers is also the history of transforming the natural landscape of rivers. The variability of rivers makes the task of protecting river scenery even more arduous. Especially, the problem of water pollution is not optimistic.

[0003] After retrieval, the publication number is: CN107806062B, which provides "A construction method of a biological filtration slope protection for river channel restoration", and provides the following technical solution: Based on a trapezoidal river channel section, it consists of a water intercepting and water distribution system and a biological filtration wetland from upstream to downstream. The water intercepting and water distribution system is set in the upper reaches of the river channel. The river channel water level is raised by using a rubber dam, and the water distribution well system uses perforated water distribution pipes to convey river water to the biological filtration wetland on the river channel slope protection. Each water distribution well corresponds to a biological filtration zone. The perforated water distribution pipes will drain water evenly along the biological filtration zone, and the river water will pass through the biological filtration layer, transition layer, and drainage layer of the biological filtration zone in sequence. Finally, the treated river water will be drained out of the system by the perforated drainage pipes and re-drained into the river channel. The present invention has the effect of purifying polluted river water, operates under no-power conditions, the system can freely arrange the number of pressure water distribution wells and biological filtration zones according to the river channel topography, the layout is flexible, does not affect the normal water discharge of the river channel, and has the function of urban landscape.

[0004] River water treatment is an important environmental protection work, aiming to protect the water quality of rivers, prevent pollution, and maintain ecological balance. The treatment of river water includes eliminating organic pollution, reducing the content of water body nutrients, controlling algal blooms, improving water color and water transparency, reducing endogenous pollution of sediment, and oxidizing pollutants in the sediment. The above technical solution filters river water by setting multiple biological filtration zones. However, the biological filtration zones are only set on the slopes on both sides and cannot completely filter the river water, resulting in poor filtration effect and a long time required to form a good water quality environment. Utility Model Content

[0005] In view of the deficiencies of the prior art, the present application provides a sedimentation and filtration system for turbid river water, which has advantages such as good filtration effect, and solves the problems that the biological filtration belt is only arranged on the slopes on both sides, cannot completely filter the river water, has poor filtration effect, and takes a long time to form a good water quality environment.

[0006] To achieve the above object, the present application provides the following technical solution: A sedimentation and filtration system for turbid river water includes two slopes. An interceptor is fixedly arranged between the two slopes. A plurality of sluices are arranged between the two interceptors. A filtration chamber is formed between two adjacent sluices. A filtration device is arranged in each filtration chamber. A vortex chamber is formed between the right side of the first sluice on the right and the two interceptors. A vortex device is arranged in the vortex chamber. The vortex device is used to make the water in the vortex chamber form an up-and-down flowing vortex.

[0007] Through the above solution, during use, the turbid river water flows into the vortex chamber, is intercepted by the first sluice on the right, and gathers in the vortex chamber. The water in the vortex chamber is stirred by the vortex device to form an up-and-down circulating vortex. The foreign matters in the river water will be evenly mixed in the river water to avoid the precipitation of foreign matters. Control the opening of the first sluice on the right, so that the river water in the vortex chamber overflows from the upper part to the first filtration chamber on the right. The filtration device in the first filtration chamber on the right filters the river water. The foreign matters stay on the upper end surface of the filtration device. The river water gathers at the bottom of the first filtration chamber on the right. When the river water at the bottom of the first filtration chamber on the right rises to the opening of the adjacent sluice on the left, the river water flows into the adjacent filtration chamber on the left and is also filtered by the filtration device. In this way, the river water is filtered step by step and finally reaches the purification standard of the river water and flows downstream.

[0008] Further, a side plate is fixedly arranged on the upper end surface of each interceptor. The sluice includes a water storage plate fixedly arranged between the two interceptors at the bottom of the riverbed, and a gate slidably connected up and down between the two side plates. The height of the water storage plate of the sluice on the left is lower than the height of the water storage plate of the sluice on the right.

[0009] Through the above solution, the gate moves downward to dock with the lower water storage plate to form an interception of the river water on the right. The gate moves upward to separate from the lower water storage plate, so that when the river water on the right reaches the height of the water storage plate, it can flow into the filtration chamber on the left side of the water storage plate from the gap between the water storage plate and the gate. In addition, when the gate moves upward, it is slidably connected up and down with the two side plates.

[0010] Further, there are three sluices. The sluice on the left, the sluice in the middle and the sluice on the right together form two adjacent filtration chambers.

[0011] Through the above solution, the river water is filtered through the two filtration chambers and finally reaches the purification standard of the river water and flows downstream.

[0012] Furthermore, at the top ends of the two side plates, there is a top plate fixedly arranged with both side plates. The eddy current device includes a vertical shaft rotatably connected to the top plate. On the outer surface of the vertical shaft located in the eddy current chamber, there is a spiral conveyor blade fixedly arranged. Between the two intercepting bodies, there is a bottom plate forming the bottom wall of the eddy current chamber fixedly arranged. The bottom end of the vertical shaft is rotatably connected to the bottom plate. On the outer surface of the top plate, there is a motor fixedly arranged. The output end of the motor passes through the top plate and is fixedly arranged with the vertical shaft.

[0013] With the above solution, during use, the motor rotates to drive the vertical shaft to rotate, so that the vertical shaft drives the spiral conveyor blade to rotate, stirring the river water in the eddy current chamber, causing the river water in the eddy current chamber to form an up-and-down circulating eddy current, making the foreign objects in the river water in the eddy current chamber evenly mix with the river water, and preventing the foreign objects in the river water from settling to the bottom of the eddy current chamber.

[0014] Furthermore, between the two intercepting bodies on the right side of the vertical shaft, there is a blocking plate slidably connected in the up-and-down direction. When the blocking plate moves upward, the blocking plate is slidably connected to the two side plates in the up-and-down direction. When the blocking plate moves downward and contacts the bottom plate, a circumferentially closed chamber is formed in the eddy current chamber.

[0015] With the above solution, when the blocking plate moves downward and contacts the bottom plate, the river water is intercepted to the right of the blocking plate, and a circumferentially closed chamber is formed in the eddy current chamber. When the blocking plate moves upward, separating the blocking plate from the bottom plate, the river water flows into the eddy current chamber through the lower part of the blocking plate.

[0016] Furthermore, cleaning plates are arranged at the bottoms of the left filtering chamber and the right filtering chamber respectively. Inside each cleaning plate, through holes are opened in the front-back direction, and a number of spray holes communicating with the corresponding through holes are opened on the upper end surface of each cleaning plate.

[0017] With the above solution, after the filtering chamber has been used for a long time and needs to be cleaned at the bottom, high-pressure water is input from one end of the through hole of the cleaning plate and flows out from the other end. When the high-pressure water flows through the through hole, it will spray out from the spray holes of the cleaning plate. The high-speed water flow stirs up the sediment deposited at the bottom of the filtering chamber. With the continuous input of high-pressure water, the water in the eddy current chamber will be gradually replaced, and at the same time, a large amount of sediment will also be carried away by the high-pressure water flow, achieving the purpose of cleaning the filtering chamber.

[0018] Further, a pump chamber is provided on the upper end surface of the front intercepting body. A water pump is fixedly arranged in the pump chamber. The output end of the water pump is fixedly communicated with two high-pressure water pipes. One end of each high-pressure water pipe away from the water pump is communicated with the front end of the through hole of the corresponding cleaning plate. The high-pressure water pipes are fixedly arranged in the front intercepting body. The input end of the water pump is fixedly communicated with a water suction pipe. One end of the water suction pipe away from the water pump is fixedly arranged on the slope protection on the right side of the baffle plate and extends between the two slope protections. The rear ends of the through holes of the two cleaning plates are both communicated with a discharge pipe. One end of the discharge pipe away from the through hole of the cleaning plate is communicated with the eddy current chamber. The discharge pipe is fixedly arranged in the rear intercepting body.

[0019] With the above solution, during use, when the sediment at the bottom of the eddy current chamber needs to be cleaned, the water pump is started, so that the water pump pumps water from between the two slope protections on the right side of the upstream baffle plate through the water suction pipe. Then the pumped river water is pressurized by the water pump to form high-pressure water and is respectively input from the two high-pressure water pipes into the front ends of the through holes of the two cleaning plates. When the high-pressure water flows through the through holes of the cleaning plates, part of the high-pressure water will spray out from the spray holes of the cleaning plates, so that the accumulated sediment at the bottom of the filtration chamber is lifted by the high-pressure water. With the continuous input of the high-pressure water, the water in the eddy current chamber will be gradually replaced. At the same time, a large amount of sediment is also carried away by the high-pressure water flow and flows out from the rear end of the through hole of the cleaning plate and is discharged into the eddy current chamber through the discharge pipe for re-step-by-step filtration of the river water. It should be noted that the step-by-step sedimentation and filtration system for turbid river water of the present application does not filter sediment. There is endless sediment in the river water and there is no need to filter it. The filtering device filters foreign matters in the river water, such as plant corpses, garbage and other sundries. Therefore, after using for a long time, sediment will precipitate at the bottom of the filtration chamber. And through the setting of the cleaning plate, the sediment precipitation in the filtration chamber can be exempted from manual cleaning, and only regular high-pressure water flushing is required. The sediment washed away by the high-pressure water is discharged into the eddy current chamber for re-filtration, not for filtering sediment, but for filtering foreign matters, because there are inevitably foreign matters washed out in the high-pressure water, and most of the sediment will flow into the downstream after step-by-step filtration, and a part of it will still precipitate to the bottom of the filtration chamber, which is inevitable. Therefore, only the cleaning plate of the eddy current chamber needs to be regularly cleaned with high-pressure water.

[0020] Further, a first threaded rod is fixedly arranged on the upper end surface of the gate. The top end of the first threaded rod penetrates upward through the top plate. A first hand wheel is threadedly connected to the outer surface of the first threaded rod above the top plate. The bottom end of the first hand wheel extends into the interior of the top plate and is rotationally connected to the top plate.

[0021] With the above solution, by rotating the first hand wheel, the first threaded rod and the gate are driven to move up and down synchronously, so as to achieve the purpose of docking and separating the bottom surface of the gate from the upper end surface of the lower water storage plate.

[0022] Further, the upper end surface of the baffle is fixedly connected with a second threaded rod. The top end of the second threaded rod extends upward through the top plate. A second handwheel is threadedly connected to the second threaded rod above the top plate. The bottom end of the second handwheel extends into the top plate and is rotatably connected to the top plate.

[0023] Through the above solution, by rotating the second handwheel, the second threaded rod and the baffle are driven to move up and down synchronously, achieving the purpose of opening and closing the baffle for the eddy current chamber.

[0024] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0025] In the sedimentation and filtration system for turbid river water, by providing a plurality of sluice gates, eddy current devices, and filtration devices, when the device is in use, the turbid river water converges in the eddy current chamber. The water in the eddy current chamber is stirred by the eddy current device to form an up-and-down circulating eddy current. The foreign matters in the river water will be evenly mixed in the river water to avoid the precipitation of foreign matters. The first sluice gate on the right side is controlled to open, so that the river water in the eddy current chamber overflows from the upper part to the first filtration chamber on the right side. The filtration device in the first filtration chamber on the right side filters the river water, and the foreign matters are retained on the upper end surface of the filtration device. The river water converges at the bottom of the first filtration chamber on the right side. When the river water at the bottom of the first filtration chamber on the right side rises to the opening of the adjacent left sluice gate, the river water flows into the adjacent left filtration chamber and is also filtered by the filtration device. In this way, the river water is filtered step by step and finally reaches the purification standard of the river water and flows downstream. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0035] Please refer to Figure 1 - Figure 6 , a turbid river water sedimentation and filtration system in this embodiment includes two slope protections 1. An intercepting body 2 is fixedly arranged between the two slope protections 1. A plurality of sluices 3 are arranged between the two intercepting bodies 2. A filtration chamber 4 is formed between two adjacent sluices 3. A filtration device 5 is arranged in each filtration chamber 4. A vortex chamber 6 is formed between the right side of the first sluice 3 on the right and the two intercepting bodies 2. A vortex device is arranged in the vortex chamber 6, and the vortex device is used to make the water in the vortex chamber 6 form an up-and-down flowing vortex.

[0036] During use, the turbid river water flows into the vortex chamber 6 and is intercepted by the first sluice 3 on the right, gathering in the vortex chamber 6. The water in the vortex chamber 6 is stirred by the vortex device to form an up-and-down circulating vortex. The foreign matters in the river water will be evenly mixed in the river water to avoid the precipitation of foreign matters. Control the first sluice 3 on the right to open, so that the river water in the vortex chamber 6 overflows from the upper part to the first filtration chamber 4 on the right. The filtration device 5 in the first filtration chamber 4 on the right filters the river water, and the foreign matters stay on the upper end surface of the filtration device 5. The river water gathers at the bottom of the first filtration chamber 4 on the right. When the river water at the bottom of the first filtration chamber 4 on the right rises to the opening of the adjacent left sluice 3, the river water flows into the adjacent left filtration chamber 4 and is also filtered by the filtration device 5. In this way, the river water is filtered step by step and finally reaches the purification standard of the river water and flows to the downstream.

[0037] In this embodiment, side plates 7 are fixedly arranged on the upper end surfaces of each intercepting body 2. The water gate 3 includes a water storage plate 8 fixedly arranged between the two intercepting bodies 2 at the bottom of the riverbed and a gate 9 slidably connected up and down between the two side plates 7. The height of the water storage plate 8 of the water gate 3 on the left side is lower than that of the water storage plate 8 of the water gate 3 on the right side. The gate 9 moves downward to dock with the lower water storage plate 8 to form an interception of the river water on the right side. The gate 9 moves upward to separate from the lower water storage plate 8, so that when the river water on the right side reaches the height of the water storage plate 8, it can flow into the filtration chamber 4 on the left side of the water storage plate 8 through the gap between the water storage plate 8 and the gate 9. In addition, when the gate 9 moves upward, it is slidably connected up and down with the two side plates 7.

[0038] In order to achieve the purpose of driving the gate 9 to move up and down, in this embodiment, a first threaded rod 10 is fixedly arranged on the upper end surface of the gate 9. The top end of the first threaded rod 10 penetrates upward through the top plate 11. A first handwheel 12 is threadedly connected to the outer surface of the first threaded rod 10 above the top plate 11. The bottom end of the first handwheel 12 extends into the interior of the top plate 11 and is rotatably connected to the top plate 11. By rotating the first handwheel 12, the first threaded rod 10 and the gate 9 are driven to move up and down synchronously, so as to achieve the purpose of docking and separating the bottom surface of the gate 9 from the upper end surface of the lower water storage plate 8.

[0039] In this embodiment, there are three water gates 3. The water gate 3 on the left side, the water gate 3 in the middle and the water gate 3 on the right side together form two adjacent filtration chambers 4. The river water is filtered through the two filtration chambers 4 and finally reaches the purification standard of the river water and flows downstream.

[0040] In order to achieve the purpose of mixing the foreign matters in the river water in the eddy current chamber 6 evenly with the river water and preventing the foreign matters in the river water from settling and remaining at the bottom of the eddy current chamber 6, in this embodiment, the eddy current device includes a vertical shaft 13 rotatably connected to the top plate 11. A spiral conveyor blade 14 is fixedly arranged on the outer surface of the vertical shaft 13 located in the eddy current chamber 6. A bottom plate 15 forming the inner bottom wall of the eddy current chamber 6 is fixedly arranged between the two intercepting bodies 2. The bottom end of the vertical shaft 13 is rotatably connected to the bottom plate 15. A motor 16 is fixedly arranged on the outer surface of the top plate 11. The output end of the motor 16 passes through the top plate 11 and is fixedly arranged with the vertical shaft 13. When in use, the motor 16 rotates to drive the vertical shaft 13 to rotate, so that the vertical shaft 13 drives the spiral conveyor blade 14 to rotate, so that the spiral conveyor blade 14 stirs the river water in the eddy current chamber 6, so that the river water in the eddy current chamber 6 forms an up and down circulating eddy current, so that the foreign matters in the river water in the eddy current chamber 6 are evenly mixed with the river water, and the foreign matters in the river water are prevented from settling to the bottom of the eddy current chamber 6.

[0041] In order to achieve the purpose of controlling the entry of river water into the eddy chamber 6, in this embodiment, a baffle 17 is slidably connected in the vertical direction between two intercepting bodies 2 on the right side of the vertical shaft 13. When the baffle 17 moves upward, the baffle 17 is slidably connected to the two side plates 7 in the vertical direction. When the baffle 17 moves downward and contacts the bottom plate 15, the river water is intercepted to the right of the baffle 17, and a circumferentially closed chamber is formed in the eddy chamber 6. When the baffle 17 moves upward, the baffle 17 is separated from the bottom plate 15, and the river water flows into the eddy chamber 6 through the lower part of the baffle 17.

[0042] In order to achieve the purpose of driving the baffle 17 to move up and down, in this embodiment, the upper end surface of the baffle 17 is fixedly connected with a second threaded rod 18. The top end of the second threaded rod 18 extends upward through the top plate 11. A second handwheel 19 is threadedly connected to the second threaded rod 18 above the top plate 11. The bottom end of the second handwheel 19 extends into the top plate 11 and is rotatably connected to the top plate 11. By rotating the second handwheel 19, the second threaded rod 18 and the baffle 17 are driven to move up and down synchronously, so as to achieve the purpose of opening and closing the eddy chamber 6 by the baffle 17.

[0043] During normal use, first rotate the second handwheel 19 to drive the baffle 17 to move upward, so that the river water on the right side of the baffle 17 flows into the eddy chamber 6. Then, the motor 16 drives the spiral conveyor 14 to rotate through the vertical shaft 13, so that the spiral conveyor 14 stirs the river water in the eddy chamber 6, causing the river water in the eddy chamber 6 to roll up and down to form an eddy. By rotating the first handwheel 12 of the right gate 9, the right gate 9 and the first threaded rod 10 move upward synchronously, so that the turbid river water in the right eddy chamber 6 flows into the right filter chamber 4 through the gap between the right gate 9 and the right storage plate 8 below. And the filtering device 5 in the right filter chamber 4 filters the river water, and foreign matters stay on the upper end surface of the filtering device 5 in the right filter chamber 4. The river water gathers at the bottom of the right filter chamber 4. When the water level of the river water in the right filter chamber 4 rises to the height of the middle storage plate 8, by rotating the first handwheel 12 of the middle gate 9, the middle gate 9 moves upward, so that the river water in the right filter chamber 4 flows into the left filter chamber 4 through the gap between the middle gate 9 and the middle storage plate 8, and is filtered by the filtering device 5 in the left filter chamber 4, so that foreign matters stay on the upper end surface of the filtering device 5 in the left filter chamber 4. The river water gathers at the bottom of the left filter chamber 4. When the water level of the river water in the left filter chamber 4 rises to the height of the left storage plate 8, by rotating the first handwheel 12 of the left gate 9, the left gate 9 moves upward, and the river water in the left filter chamber 4 flows to the downstream through the gap between the left gate 9 and the left storage plate 8, completing the secondary filtration of the turbid river water.

[0044] Since the filtration chamber 4 of the present application also has a sedimentation effect, after the filtration chamber 4 has been used for a long time, a large amount of sediment will accumulate at the inner bottom wall of the filtration chamber 4. To achieve the purpose of cleaning the sediment at the bottom of the filtration chamber 4, in this embodiment, cleaning plates 20 are provided at the bottoms of the left filtration chamber 4 and the right filtration chamber 4. Through holes 21 are formed in each cleaning plate 20 in the front-rear direction, and a number of spray holes 22 communicating with the corresponding through holes 21 are formed in the upper end surface of each cleaning plate 20; when the filtration chamber 4 has been used for a long time and the bottom of the filtration chamber 4 needs to be cleaned, high-pressure water is input from one end of the through hole 21 of the cleaning plate 20 and flows out from the other end. When the high-pressure water flows through the through hole 21, it will spray out from the spray hole 22 of the cleaning plate 20. The high-speed water flow stirs up the sediment deposited at the bottom of the filtration chamber 4. As the high-pressure water continues to be input, the water in the eddy chamber 6 will be gradually replaced, and at the same time, a large amount of sediment will also be carried away by the high-pressure water flow, achieving the purpose of cleaning the filtration chamber 4.

[0045] To achieve the purpose of inputting high-pressure water into the through hole 21 of the cleaning plate 20, in this embodiment, a pump chamber is formed in the upper end surface of the front intercepting body 2. A water pump 23 is fixedly arranged in the pump chamber. The output end of the water pump 23 is fixedly communicated with two high-pressure water pipes 24. One end of each high-pressure water pipe 24 away from the water pump 23 is communicated with the front end of the through hole 21 of the corresponding cleaning plate 20. The high-pressure water pipe 24 is fixedly arranged in the front intercepting body 2; the input end of the water pump 23 is fixedly communicated with a water suction pipe 25. One end of the water suction pipe 25 away from the water pump 23 is fixedly arranged on the slope protection 1 to the right of the baffle plate 17 and extends between the two slope protections 1; the rear ends of the through holes 21 of the two cleaning plates 20 are both communicated with a discharge pipe 26 fixedly arranged in the rear intercepting body 2. One end of the discharge pipe 26 away from the through hole 21 of the cleaning plate 20 is communicated with the eddy chamber 6.

[0046] During use, when the sediment at the bottom of the eddy current chamber 6 needs to be cleaned, the water pump 23 is started, so that the water pump 23 pumps water from between the two slope protections 1 on the right side of the upstream baffle 17 through the water suction pipe 25. Then, the pumped river water forms high-pressure water through the pressurization of the water pump 23 and is input from the front ends of the through holes 21 of the two cleaning plates 20 through the two high-pressure water pipes 24 respectively. When the high-pressure water flows through the through holes 21 of the cleaning plate 20, part of the high-pressure water will be ejected from the spray holes 22 of the cleaning plate 20, so that the accumulated sediment at the bottom of the filtration chamber 4 is flushed up by the high-pressure water. With the continuous input of the high-pressure water, the water in the eddy current chamber 6 will be gradually replaced. At the same time, a large amount of sediment is also carried away by the high-pressure water flow and flows out from the rear ends of the through holes 21 of the cleaning plate 20 and is discharged into the eddy current chamber 6 through the discharge pipe 26 for re-stepped filtration of the river water; it should be noted that the stepped sedimentation and filtration system for turbid river water of the present application does not filter sediment. There is endless sediment in the river water and there is no need to filter it. The filtration device 5 filters foreign matters in the river water, such as plant corpses, garbage and other sundries. Therefore, after long-term use, sediment will precipitate at the bottom of the filtration chamber 4. The setting of the cleaning plate 20 can prevent the sediment precipitation in the filtration chamber 4 from being manually cleaned, and only regular high-pressure water flushing is required. The sediment washed away by the high-pressure water is discharged into the eddy current chamber 6 for re-filtration, not for filtering sediment, but for filtering foreign matters, because there are inevitably foreign matters washed out in the high-pressure water, and most of the sediment will flow into the downstream after stepped filtration, and a part of it will still precipitate to the bottom of the filtration chamber 4, which is inevitable. Therefore, it is only necessary to regularly clean the cleaning plate 20 of the eddy current chamber 6 with high-pressure water.

[0047] The working principle of the above embodiments is as follows: During normal use, first rotate the second handwheel 19 to drive the baffle 17 to move upward, so that the river water on the right side of the baffle 17 flows into the eddy chamber 6. Then, drive the spiral conveyor blade 14 to rotate through the motor 16 via the vertical shaft 13, so that the spiral conveyor blade 14 stirs the river water in the eddy chamber 6, causing the river water in the eddy chamber 6 to roll up and down to form an eddy. By rotating the first handwheel 12 of the right gate 9, the right gate 9 and the first threaded rod 10 move upward synchronously, so that the turbid river water in the right eddy chamber 6 flows into the right filter chamber 4 through the gap between the right gate 9 and the right water storage plate 8 below. And the filtering device 5 in the right filter chamber 4 filters the river water, and foreign matters remain on the upper end surface of the filtering device 5 in the right filter chamber 4. The river water gathers at the bottom of the right filter chamber 4. When the water level of the river water in the right filter chamber 4 rises to the height of the middle water storage plate 8, by rotating the first handwheel 12 of the middle gate 9, the middle gate 9 moves upward, so that the river water in the right filter chamber 4 flows into the left filter chamber 4 through the gap between the middle gate 9 and the middle water storage plate 8, and is filtered by the filtering device 5 in the left filter chamber 4, so that foreign matters remain on the upper end surface of the filtering device 5 in the left filter chamber 4. The river water gathers at the bottom of the left filter. When the water level of the river water in the left filter chamber 4 rises to the height of the left water storage plate 8, by rotating the first handwheel 12 of the left gate 9, the left gate 9 moves upward, and the river water in the left filter chamber 4 flows downstream through the gap between the left gate 9 and the left water storage plate 8, completing the secondary filtration of the turbid river water.
