Description

Technical Field

[0001] The utility model belongs to the technical field of self-flowing water of sedimentation tanks, and particularly relates to a self-flowing water structure of a sedimentation tank for solar cell processing. Background Technique

[0002] During the processing of solar cells, the sedimentation tank mainly coagulates, adds medicine, and precipitates the passing water. The precipitated water is transported to the pH adjustment intermediate water tank through a water delivery pipe for subsequent treatment. When the water precipitates in the sedimentation tank, most of the impurities in the water will sink to the bottom of the tank after being coagulated by the medicine, but there will still be a small part of floating substances floating on the water surface all the time, resulting in the most impurities at the bottom of the water in the sedimentation tank, followed by the surface, and instead the water quality in the middle part is the best.

[0003] In the prior art, the water outlet pipe of the sedimentation tank is connected to the tank wall. When the water in the sedimentation tank is higher than the lower wall of the water outlet pipe, the water will automatically flow into the water outlet pipe under the action of gravity, and the floating substances on the water surface will also enter the pH adjustment intermediate water tank along with the water flow, which may cause the water quality in the pH adjustment intermediate water tank not to meet the production standard and affect the production and processing of solar cells.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a self-flowing water structure of a sedimentation tank for solar cell processing.

[0005] The information disclosed in this background art section is only intended to enhance the understanding of the overall background of the present utility model and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art. Summary of the Utility Model

[0006] The purpose of the present utility model is to provide a self-flowing water structure of a sedimentation tank for solar cell processing, which can be used to solve the above problems.

[0007] To achieve the above purpose, a specific embodiment of the present utility model provides a self-flowing water structure of a sedimentation tank for solar cell processing, including a sedimentation tank. An inlet pipe, an outlet pipe, and a sewage pipe are fixedly connected to the sedimentation tank. An opening and closing assembly is installed on the sedimentation tank. The opening and closing assembly includes a frame body fixedly connected to the inner wall of the sedimentation tank. The position of the frame body matches that of the outlet pipe. A sealing plate is slidably connected in the frame body. The opening and closing assembly further includes a buoyancy ball. A sliding column is connected between the buoyancy ball and the sealing plate. When the buoyancy ball floats, the sealing plate opens. When the buoyancy ball descends, the sealing plate seals the frame body. The opening and closing assembly can automatically open or close the frame body as the water level rises or falls, realizing automatic water discharge.

[0008] In one or more embodiments of the present utility model, the frame body is rectangular, and first sealing grooves matching the sealing plates are formed on the inner walls of the four circles of the frame body, and the sealing plates are slidably connected in the first sealing grooves.

[0009] In one or more embodiments of the present utility model, a cover plate is fixedly connected to the sealing plate, a second sealing groove matching the cover plate is formed on the upper panel of the frame body, and the first sealing groove penetrates the bottom wall of the second sealing groove. The sealing plate can be drawn out of the frame body. When the sealing plate is inserted into the frame body, the frame body is sealed to prevent water from flowing into the water outlet pipe from the frame body.

[0010] In one or more embodiments of the present utility model, a connecting block is fixedly connected to the end face of the cover plate away from the sealing plate, and the sliding column is fixedly connected to the connecting block.

[0011] In one or more embodiments of the present utility model, a magnet block is provided between the connecting block and the buoyancy ball. The magnet block is fixedly connected to the sliding column, and the sliding column penetrates the magnet block. The weight of the magnet block can give a downward pressure to the sealing plate, making the sealing plate more stable in the first sealing groove.

[0012] In one or more embodiments of the present utility model, a filter screen is installed on the frame body. A threaded hole is formed on the end face of the side wall of the frame body away from the sedimentation tank. A bolt matching the threaded hole is provided on the filter screen, and the filter screen is threadedly connected to the frame body through the bolt. The filter screen filters fine particles in the water, which can improve the water quality flowing out of the water outlet pipe.

[0013] In one or more embodiments of the present utility model, a cleaning assembly is fixedly connected to the connecting block.

[0014] In one or more embodiments of the present utility model, the cleaning assembly includes a fixing plate. The fixing plate is L-shaped, and a cleaning strip is fixedly connected to the fixing plate. As the fixing plate moves downward, the cleaning strip can automatically brush the particles adhered to the filter screen clean.

[0015] In one or more embodiments of the present utility model, a locking block is fixedly connected to the inner wall of the sedimentation tank, and the upper panel of the locking block is in contact with the lower panel of the magnet block.

[0016] In one or more embodiments of the present utility model, a through hole matching the sliding column is formed on the locking block, and the sliding column is slidably connected in the through hole on the locking block. When the magnet block slides up and down following the sliding column, it can be adsorbed on the locking block. Only when the water level is higher than the buoyancy ball, the buoyancy will be greater than the magnetic attraction between the magnet block and the locking block, and the opening and closing assembly can be opened, so that the floating objects on the water surface will not flow out of the water outlet pipe.

[0017] Compared with the prior art, the self-flowing water structure of the sedimentation tank for solar cell processing of the present utility model can make the water in the middle part of the sedimentation tank flow out automatically from the water outlet pipe, which can effectively improve the water quality of the water flowing out of the sedimentation tank and contribute to the production of solar cells.

Detailed Description of the Embodiment

[0027] In order to enable those skilled in the art to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] As Figure 1 shown, the self-flowing water structure of the sedimentation tank for solar cell processing in an embodiment of the present utility model includes a sedimentation tank 1, on which a water inlet pipe 11, a water outlet pipe 12 and a sewage pipe 13 are welded. Water enters the inside of the sedimentation tank 1 from the water inlet pipe 11. When the water in the sedimentation tank 1 is higher than the lower wall of the water outlet pipe 12, the water in the sedimentation tank 1 flows out of the sedimentation tank 1 from the water outlet pipe 12 under the action of gravity. After long-term use, a large amount of impurities will accumulate on the bottom wall of the sedimentation tank 1. Opening the sewage pipe 13 can discharge the accumulated impurities in the sedimentation tank 1.

[0029] As Figures 1 to 4 shown, when the water surface in the sedimentation tank 1 is higher than the bottom wall of the water outlet pipe 12, the floating objects floating on the water will enter the water outlet pipe 12 along with the water flow, resulting in poor water quality flowing out of the water outlet pipe 12. In order to enable the water in the middle part of the sedimentation tank 1 to flow out of the water outlet pipe 12 automatically, an opening and closing assembly is installed on the sedimentation tank 1. The opening and closing assembly includes a frame body 2, and the four outer walls of the frame body 2 are welded to the inner wall of the sedimentation tank 1, and the position of the frame body 2 matches that of the water outlet pipe 12. A sealing plate 24 is slidably connected in the frame body 2.

[0030] Specifically, the frame body 2 is rectangular, and first sealing grooves 22 matching the sealing plate 24 are provided on the four inner walls of the frame body 2. A cover plate 25 is integrally formed on the upper panel of the sealing plate 24. A second sealing groove 21 matching the cover plate 25 is provided on the upper panel of the frame body 2. The first sealing groove 22 penetrates the bottom wall of the second sealing groove 21, and the sealing plate 24 can slide in the frame body 2. When the sealing plate 24 is completely inside the frame body 2, the cover plate 25 covers the second sealing groove 21, and the bottom of the sealing plate 24 is inserted into the first sealing groove 22 on the bottom wall of the frame body 2, and the sealing plate 24 can block the frame body 2. Specifically, the sealing plate 24 seals the first sealing groove 22, and the cover plate 25 seals the second sealing groove 21, so that the water inside the sedimentation tank 1 cannot flow from the frame body 2 to the water outlet pipe 12.

[0031] A connecting block 26 is integrally formed on the end face of the cover plate 25 away from the sealing plate 24. A sliding column 27 is welded to the end of the connecting block 26 away from the cover plate 25. A buoyancy ball 29 is bonded to the end of the sliding column 27 away from the connecting block 26.

[0032] Specifically, when the water level in the sedimentation tank 1 is higher than the bottom wall of the frame 2, due to the partition of the sealing plate 24, the water cannot flow into the outlet pipe 12, so the floating objects on the water surface also cannot flow into the outlet pipe 12. When the water level in the sedimentation tank 1 rises to the position of the buoyancy ball 29, under the buoyancy force, the buoyancy ball 29 drives the sealing plate 24 to float upward through the sliding column 27, the bottom wall of the sealing plate 24 moves away from the bottom wall of the frame 2, and the water can flow from the inside of the frame 2 into the outlet pipe 12 to complete self-flow. At this time, the water level in the sedimentation tank 1 is much higher than that of the frame 2, and the floating objects floating on the water surface will not enter the outlet pipe 12, so the water quality flowing out of the sedimentation tank 1 can be effectively improved.

[0033] It should be noted that when the water in the sedimentation tank 1 precipitates, there will be sediment falling on the inner wall of the water inlet of the frame 2. As Figures 1 to 3 shown, a filter screen 3 is installed on the frame 2, and the filter screen 3 can block the frame 2 to prevent the precipitated particles in the water from falling into the frame 2.

[0034] Specifically, a threaded hole 23 is provided on one end face of the side wall of the frame 2 away from the sedimentation tank 1, and a bolt 31 matching the threaded hole 23 is provided on the filter screen 3. The filter screen 3 is threadedly connected to the frame 2 through the bolt 31. The water in the sedimentation tank 1 enters the frame 2 after being filtered by the filter screen 3, further improving the water quality of the water flowing out of the frame 2.

[0035] As Figures 2 to 6 shown, a magnet block 28 is welded on the outer wall of the sliding column 27, the sliding column 27 penetrates through the magnet block 28, and the magnet block 28 is arranged between the buoyancy ball 29 and the connecting block 26. A locking block 14 is welded on the inner wall of the sedimentation tank 1, the upper panel of the locking block 14 is in contact with the lower panel of the magnet block 28, and a through hole matching the outer diameter of the sliding column 27 is provided on the locking block 14. The sliding column 27 also penetrates through the locking block 14, and the sliding column 27 can slide in the through hole on the locking block 14.

[0036] Specifically, when the water level in the sedimentation tank 1 is lower than the buoyancy ball 29, the magnet block 28 is magnetically attracted to the locking block 14, and the suction force between the magnet block 28 and the locking block 14 can exert a downward pressure on the cover plate 25 and the sealing plate 24, making the sealing effect of the sealing plate 24 and the cover plate 25 on the frame 2 better.

[0037] When the water level in the sedimentation tank 1 submerges the buoyancy ball 29, the buoyancy of the buoyancy ball 29 is greater than the magnetic suction force between the magnet block 28 and the locking block 14, the magnet block 28 is separated from the locking block 14, the buoyancy ball 29 floats upward and drives the sealing plate 24 to move upward, and the opening degree of the frame 2 will also become larger, so that the water in the sedimentation tank 1 quickly flows from the inside of the frame 2 to the outlet pipe 12.

[0038] When water flows into the frame 2, the particles that are being precipitated in the water will flow toward the frame 2 along with the water flow, and the particles flowing toward the frame 2 will also be blocked by the filter 3. After long-term use, more particles will adhere to the surface of the filter 3, affecting the flow of water into the frame 2. Further, a cleaning component is provided on the connecting block 26. The cleaning component includes a fixing plate 261, the fixing plate 261 is L-shaped, one end of the fixing plate 261 is welded to the connecting block 26, and a cleaning strip 262 is integrally formed on the side wall of the fixing plate 261 away from the connecting block 26, and the cleaning strip 262 is attached to the surface of the filter 3.

[0039] Specifically, when the buoyancy ball 29 floats up, the cleaning strip 262 can scrape off the particles adhering to the surface of the filter screen 3, and when water flows through the frame 2, the filter screen 3 remains clean, without affecting the flow of water from the filter screen 3 into the frame 2. After the water level drops, the cleaning strip 262 also drops, and can scrape off the particles adhering to the filter screen 3 again.

[0040] Furthermore, a limit plate 241 is integrally formed on the side wall of the sealing plate 24. When the sealing plate 24 is driven to float up by the buoyancy ball 29, if the limit plate 241 can resist the inner wall of the upper panel of the frame 2, the sealing plate 24 is prevented from detaching from the frame 2.

[0041] The water in the sedimentation tank 1 continues to flow out, and as the water level drops, the buoyancy ball 29 also drops, and the magnet block 28 and the locking block 14 are magnetically attracted together after contacting. At this time, the bottom wall of the sealing plate 24 is also inserted into the first sealing groove 22 on the bottom wall of the frame 2.

[0042] When using, Figure 5 and Figure 6 As shown, when the water level in the sedimentation tank 1 rises above the buoyancy ball 29, the buoyancy ball 29 drives the connection block 26 and the sealing plate 24 to float together, and the frame 2 forms a passage. At the same time, the cleaning strip 262 scrapes off the particles adhering to the filter screen 3, and the water flows into the outlet pipe 12 from the frame 2 after being filtered by the filter screen 3. When the water level in the sedimentation tank 1 drops, the buoyancy ball 29 drops, the magnet block 28 is magnetically attracted to the locking block 14, and the sealing plate 24 is plugged into the first sealing groove 22 on the bottom wall of the frame 2, sealing the frame 2, and the water surface will always be above the frame 2, and floating objects on the water surface will not enter the frame 2, which can effectively prevent floating objects on the water surface from flowing out of the frame 2.
