Description

Technical Field

[0001] This utility model relates to the technical field of low-dose polyaluminum chloride purification devices for slightly polluted water bodies, specifically a low-dose polyaluminum chloride purification device for slightly polluted water bodies. Background Technology

[0002] The low-dose polyaluminum chloride purification device for slightly polluted water is a device used to treat slightly polluted water. By adding a low dose of polyaluminum chloride as a flocculant, suspended particles and organic matter in the water are aggregated to form larger flocs, thereby achieving the purpose of water purification.

[0003] Currently, Chinese patent CN217600444U discloses a high-efficiency and environmentally friendly polyaluminum chloride water purification device, including a purification tank. A connecting seat is connected to the outer wall of the bottom of the purification tank, and a drain pipe is connected to the middle of the bottom of the purification tank. A filter plate is installed on the inner wall of the drain pipe. A top cover is snapped onto the top of the purification tank, and a rotary motor is installed in the middle of the top cover. A connecting rod is provided between the rotary motor and the lower end of the top cover, and a stirring assembly is connected to the inner wall of the connecting rod. A replacement assembly is installed inside the purification tank. A water inlet pipe is connected to the right side of the top cover, and a feeding assembly is connected to the left side of the top cover. The feeding assembly includes a feeding hood and a conveying frame. The feeding hood is connected to the left side of the top cover, and the conveying frame is connected to the bottom of the feeding hood. The replacement assembly facilitates the removal of the replacement box from the purification tank later. By separating the clips of the replacement box from the purification tank, the replacement box can be disassembled for quick cleaning.

[0004] The above-mentioned problems still exist in use. The scraper is fixedly connected to the connecting frame. If the inner wall of the purification box is worn after long-term use, the gap between the scraper and the inner wall will increase, which will make it impossible to effectively scrape off the flocs adhering to the box wall, affecting the uniformity of stirring and the subsequent sedimentation effect.

Anti-detachment components for preventing the corresponding scrapers from detaching are provided on the opposite sides of both sets of limiting grooves. An inspection port for inspecting the interior of the tank is opened on the top of the other side of the tank.

[0008] The elastic pusher includes hollow columns fixedly installed in the middle of opposite sides of the two sets of limiting grooves. Each set of hollow columns has a spring inside its opposite end. Each set of springs has a sliding disc at its opposite end. Each set of sliding discs has a connecting rod fixedly connected to its opposite end. Each set of connecting rods has a sliding sealing end that passes through the corresponding hollow column and limiting groove and abuts against the surface of the corresponding limiting plate.

[0009] As a preferred technical solution, the detachable component package is fixedly sleeved on the upper and lower surfaces of the transmission rod with fixing rings. Connecting plates are fixedly connected to both sides of the two sets of fixing rings. Limiting clips are respectively sleeved on the upper surfaces of the two sets of connecting plates facing away from each other. The ends of the two sets of limiting clips are fixedly connected to the surfaces of the corresponding side limiting grooves. Fixing bolts are inserted into the tops of the two sets of limiting clips. The ends of the two sets of fixing bolts pass downward through the corresponding side limiting clips and are threaded to the ends of the corresponding side connecting plates. The ends of the two sets of connecting plates located below are connected to the lower surfaces of the corresponding side limiting grooves through connectors.

[0010] As a preferred technical solution, the connector includes a connector plate that is fixedly installed on the lower part of one side of the two sets of limiting grooves respectively. The top of the two sets of connecting plates located below are provided with sockets corresponding to the connector plates. The ends of the two sets of connector plates are bent downward and inserted into the inner cavity of the corresponding side sockets.

[0011] As a preferred technical solution, the lower part of the opposite side of the two sets of limiting grooves is respectively engaged with U-shaped clips, and the ends of the two sets of U-shaped clips are respectively fixedly connected to the ends of the corresponding side connecting plates.

[0012] As a preferred technical solution, the anti-detachment component includes guide rods respectively inserted into the upper and lower parts of the opposite side of two sets of limiting grooves. The two sets of guide rods on the same side slide through the corresponding side limiting grooves and are fixedly connected to threaded rods. Threaded holes are opened on the opposite side of the two sets of limiting plates and at positions corresponding to each set of threaded rods. Each set of threaded rods is threadedly connected to the inner cavity of the threaded hole at the corresponding position. A turntable is fixedly connected to the end of each guide rod. The length of the guide rod is greater than the maximum sliding stroke of the limiting plate in the limiting groove, and the diameter of the turntable is greater than the diameter of the through hole of the guide rod in the limiting groove.

[0014] As a preferred technical solution, the surfaces of both sets of scrapers are coated with a wear-resistant coating.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model, through the setting of the elastic pusher, enables the scraper to always be in close contact with the inner wall of the tank under the action of the spring force. Even if the tank wears out due to long-term use, it can adaptively adjust the gap between the scraper and the inner wall, effectively scraping off the flocs attached to the tank wall, ensuring the uniformity of mixing and improving the processing.

[0017] 2. With the addition of detachable parts, this utility model eliminates the need for complex tools during equipment maintenance or component replacement. By simply unscrewing the fixing bolts and pulling out the plug plate, the limiting groove can be quickly separated from the transmission rod, facilitating the inspection and replacement of components such as scrapers and limiting grooves. This reduces maintenance difficulty and time costs, and improves the maintainability of the equipment.

[0018] 3. This utility model, through the setting of the anti-detachment component, on the one hand, the guide rod provides precise guidance for the sliding of the limiting plate in the limiting groove, ensuring that the limiting plate can only slide in the horizontal direction and preventing it from deviating or getting stuck. On the other hand, the setting of the turntable effectively limits the sliding range of the limiting plate, preventing the limiting plate from falling out of the limiting groove, ensuring that the scraper is always in an effective working position under the action of the elastic pushing component, thus improving the safety and reliability of the device operation. At the same time, the threaded rod fixedly connected to the end of the guide rod is threaded to the inner cavity of the threaded hole on the surface of the limiting plate, which facilitates the disassembly of the guide rod and greatly improves the convenience of maintenance.

[0028] 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.

[0029] Please see Figure 1-3This embodiment provides a low-dose polyaluminum chloride purification device for slightly polluted water, including a tank 100. A feed pipe 101 for feeding polyaluminum chloride into the tank 100 is connected to the top of one side of the tank 100. A discharge pipe 104 is connected to the bottom of one side of the tank 100, and a valve 103 is connected to the outlet end of the discharge pipe 104. A transmission rod 201 is rotatably connected inside the tank 100. Both ends of the transmission rod 201 are respectively connected to limiting grooves 402 via detachable parts. The openings of the two sets of limiting grooves 402 are arranged opposite to each other, and limiting plates 400 are slidably connected to the inner cavities of both sets of limiting grooves 402. Each of the two sets of limiting plates 400 has a scraper 401 fixedly connected to one of their opposite ends. The ends of the two sets of scrapers 401 pass through the openings of the corresponding side limiting grooves 402 and contact the corresponding side inner wall of the tank 100. Each of the two sets of limiting grooves 402 has an elastic pushing member that pushes the scraper 401 outward on one side. The top of the tank 100 has a drive assembly for rotating the transmission rod 201. Each of the two sets of limiting grooves 402 has an anti-detachment assembly to prevent the corresponding side scraper 401 from detaching on one side. The other side of the top of the tank 100 has an inspection port 102 for inspecting the inside of the tank 100.

[0030] The elastic pusher includes hollow columns 503 fixedly installed in the middle of the opposite side of the two sets of limiting grooves 402. Each set of hollow columns 503 has a spring 502 inside its opposite end. The opposite ends of the two sets of springs 502 are in contact with sliding discs 501. The opposite ends of the two sets of sliding discs 501 are fixedly connected to connecting rods 500. The opposite ends of the two sets of connecting rods 500 slide and seal through the corresponding hollow column 503 and limiting groove 402 and abut against the surface of the corresponding limiting plate 400. Through the setting of the elastic pusher, the scraper 401 can always be tightly attached to the inner wall of the tank 100 under the elastic force of the spring 502. Even if the tank 100 is worn due to long-term use, the gap between the scraper 401 and the inner wall can be adjusted adaptively to effectively scrape off the flocs attached to the tank wall, ensure the uniformity of mixing, and improve the processing efficiency.

[0031] The detachable component package includes fixing rings 202 that are fixedly sleeved on the upper and lower surfaces of the transmission rod 201. Connecting plates 204 are fixedly connected to both sides of the two sets of fixing rings 202. Limiting clips 300 are respectively fitted onto the upper surfaces of the opposite ends of the two sets of connecting plates 204 located at the top. The ends of the two sets of limiting clips 300 are fixedly connected to the surfaces of the corresponding side limiting grooves 402. Fixing bolts 301 are inserted into the tops of the two sets of limiting clips 300, and the ends of the two sets of fixing bolts 301 penetrate downwards through the corresponding side limiting clips 300 and are threaded together. The ends of the two sets of connecting plates 204 located below are connected to the lower surface of the corresponding side limiting groove 402 via plug-in parts. With the setting of detachable parts, during equipment maintenance or component replacement, no complicated tools are required. By unscrewing the fixing bolts 301 and pulling out the plug-in plate 303, the limiting groove 402 can be quickly separated from the transmission rod 201. This facilitates the inspection and replacement of components such as scraper 401 and limiting groove 402, reduces maintenance difficulty and time cost, and improves the maintainability of the equipment.

[0032] The connector includes a connector plate 303 fixedly installed on the lower part of one side of each of the two sets of limiting grooves 402. The top of the opposite ends of the two sets of connecting plates 204 located below are provided with sockets 304 corresponding to the connector plates 303. The ends of the two sets of connector plates 303 are bent downward and inserted into the inner cavity of the corresponding sockets 304. Through the design of the connector, after the downward bent connector plate 303 is inserted into the socket 304, it can effectively limit the horizontal displacement of the limiting groove 402 and prevent it from loosening during equipment operation. At the same time, it cooperates with the upper limiting clip 300 and fixing bolt 301 to form a double fixing structure, ensuring that the components are firmly connected during high-speed rotation and stirring, thus improving the reliability of equipment operation.

[0033] Among them, the lower part of the opposite side of the two sets of limiting grooves 402 is respectively engaged with U-shaped clips 302. The ends of the two sets of U-shaped clips 302 are respectively fixedly connected to the ends of the corresponding side connecting plates 204. With the setting of U-shaped clips 302, the U-shaped clips 302 can effectively prevent the limiting grooves 402 from shaking or displacing, ensuring the stability of the scraper 401's trajectory during operation, avoiding poor contact between the scraper 401 and the inner wall of the tank 100 due to loose connection, thereby improving the scraping effect and the stability of equipment operation.

[0034] The anti-detachment component includes guide rods 405 inserted into the upper and lower parts of two sets of limiting grooves 402 on opposite sides. The two sets of guide rods 405 on the same side slide through the corresponding limiting grooves 402 and are fixedly connected to threaded rods 404. Threaded holes 403 are provided on opposite sides of the two sets of limiting plates 400, corresponding to each set of threaded rods 404. Each set of threaded rods 404 is threaded into the inner cavity of the corresponding threaded hole 403. A turntable 406 is fixedly connected to the end of each guide rod 405. The length of the guide rod 405 is greater than the maximum sliding stroke of the limiting plate 400 within the limiting groove 402, and the diameter of the turntable 406 is greater than the diameter of the through hole in the limiting groove 402 of the guide rod 405. This anti-detachment mechanism... The design of the detachment assembly serves two purposes. First, the guide rod 405 provides precise guidance for the sliding of the limiting plate 400 within the limiting groove 402, ensuring that the limiting plate 400 can only slide horizontally and preventing it from shifting or jamming. Second, the turntable 406 effectively limits the sliding range of the limiting plate 400, preventing it from detaching from the limiting groove 402 and ensuring that the scraper 401 remains in an effective working position under the action of the elastic pusher, thus improving the safety and reliability of the device operation. At the same time, the threaded rod 404 fixedly connected to the end of the guide rod 405 is threaded into the inner cavity of the threaded hole 403 on the surface of the limiting plate 400, facilitating the disassembly of the guide rod 405 and greatly improving maintenance convenience.

[0035] The drive assembly includes a drive motor 200 fixedly installed on the top of the tank 100, and the end of the transmission rod 201 extends upward through the tank 100 and is keyed to the output shaft of the drive motor 200. The drive assembly provides a stable and reliable power output to the transmission rod 201.

[0036] Both sets of scrapers 401 are coated with a wear-resistant coating 407. The wear-resistant coating 407 significantly improves the wear resistance of the scrapers 401, extends their service life, reduces the frequency of replacement due to wear, reduces equipment maintenance costs and downtime, and ensures that the scrapers 401 always maintain a good scraping effect, thus improving the long-term operational stability of the water purification device.

[0037] Among them, the wear-resistant coating 407 is one or a combination of metal-based wear-resistant coating 407, ceramic coating, and polymer coating.

[0038] Working principle;

[0039] First, a low dose of polyaluminum chloride from slightly polluted water is introduced into the tank 100 through the feed pipe 101. At the same time, the water to be purified also enters the tank 100. Then, the drive motor 200 located at the top of the tank 100 is started. The output shaft of the drive motor 200 drives the transmission rod 201 to rotate. The transmission rod 201 further drives the limiting grooves 402 at both ends to rotate. Since the limiting plate 400 is slidably connected to the limiting groove 402 and the scraper 401 is fixed on the limiting plate 400, the scraper 401 will move in a circle around the center of the tank 100 together with the limiting groove 402.

[0040] During the rotation of scraper 401, polyaluminum chloride and water are fully mixed and stirred to achieve water purification. After purification, valve 103 at the outlet end of discharge pipe 104 is opened, and the purified water is discharged from tank 100 through discharge pipe 104.

[0041] The spring 502 in the elastic pusher is in a compressed state. Its elastic force is transmitted to the limiting plate 400 through the sliding plate 501 and the connecting rod 500, thereby pushing the scraper 401 to always be in close contact with the inner wall of the tank 100. Even if the inside of the tank 100 is worn due to long-term use, the spring 502 can adaptively compensate for the gap, ensuring that the scraper 401 is always in contact with the inner wall of the tank 100, effectively scraping off the flocs adhering to the tank wall, maintaining the uniformity of stirring, and ensuring the subsequent sedimentation effect.

[0042] Furthermore, when the scraper 401 needs to be repaired or replaced, simply unscrew the fixing bolt 301, pull out the plug plate 303, and the limiting groove 402 can be removed from the transmission rod 201 and pulled out from the inspection port 102. At the same time, rotate the turntable 406 to unscrew the threaded rod 404 from the threaded hole 403, thereby causing the guide rod 405 to disengage from the limiting plate 400. Then, pull the limiting plate 400 upwards, thereby pulling the limiting plate 400 and the scraper 401 out of the inner cavity of the limiting groove 402 together.

[0043] Then, press the connecting rod 500 inward to move the sliding plate 501 inward and compress the spring 502. Take out the new limiting plate 400 and the scraper 401 and insert them into the inner cavity of the limiting groove 402 so that the surface of the limiting plate 400 contacts the connecting rod 500. Use the guide rod 405 to pass through the limiting groove 402. At the same time, rotate the turntable 406 so that the threaded rod 404 at its end is threaded into the inner cavity of the corresponding side threaded hole 403.

[0044] At this time, the limiting groove 402 is inserted into the tank body 100 through the inspection port 102. The limiting clip 300 located on the upper side of the limiting groove 402 is engaged with the end of the connecting plate 204, and the limiting groove 402 is pushed down so that it is fully engaged with the surface of the connecting plate 204. The end of the insertion plate 303 on the lower surface of the limiting groove 402 is inserted into the insertion port 304. Then, the fixing bolt 301 is used to pass through the limiting clip 300 and threaded to the end of the connecting plate 204, thereby fixing the limiting groove 402.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
