Description

Technical Field

[0001] This utility model relates to the technical field of polyaluminum chloride processing equipment, specifically to a polyaluminum chloride dissolving equipment with an anti-clogging structure. Background Technology

[0002] Polyaluminum chloride (PAC) is an inorganic compound used as an emerging water purification material and inorganic polymeric coagulant, widely applied in urban water supply and drainage purification, sewage treatment, and other fields. Before actual use, solid PAC typically needs to be dissolved and mixed with water. This requires specialized dissolution equipment to achieve an efficient and uniform dissolution process. Due to the inherent properties of PAC, it is prone to clumping, resulting in undissolved lumps in the solution. This reduces product quality and may cause pipeline blockages during subsequent transportation and use.

[0003] Traditional anti-clogging structures often use tapping on the filter screen to achieve the anti-clogging effect. However, prolonged tapping can easily damage the filter screen. Therefore, a polyaluminum chloride dissolving device with an anti-clogging structure is proposed to solve the problems mentioned above. Utility Model Content

[0004] To solve the above-mentioned technical problems, a polyaluminum chloride dissolving device with an anti-clogging structure is provided. This technical solution solves the problem mentioned in the background that the traditional anti-clogging structure is prone to damage to the filter screen due to prolonged knocking.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A polyaluminum chloride dissolving device with an anti-clogging structure includes a dissolving tank. A frame is fixedly connected inside the dissolving tank. Two guide rods are fixedly connected between the upper and lower inner walls of the dissolving tank on the right side of the frame. A lead screw is rotatably connected between the upper and lower inner walls of the dissolving tank on the right side of the guide rods. A movable seat is threadedly connected to the outer surface of the lead screw. A cleaning roller is rotatably connected between the two movable seats. Several evenly distributed cleaning heads are fixedly connected to the outer surface of the cleaning roller.

[0016] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0017] Reference Figures 1-6 As shown, a polyaluminum chloride dissolving device with an anti-clogging structure includes a dissolving tank 1. A frame 5 is fixedly connected inside the dissolving tank 1. The frame 5 is used to fix and support a filter screen 6, ensuring the filter screen 6 remains stable during operation and preventing displacement due to material impact or cleaning operations. Two guide rods 7 are fixedly connected between the upper and lower inner walls of the dissolving tank 1 on the right side of the frame 5. A lead screw 8 is rotatably connected between the upper and lower inner walls of the dissolving tank 1 on the right side of the guide rods 7. Two drive motors 9 are fixedly installed on the upper surface of the dissolving tank 1. The output ends of both drive motors 9 penetrate the upper surface of the dissolving tank 1 and are fixedly connected to the upper ends of the two lead screws 8 respectively. A movable seat 10 is threadedly connected to the outer surface of the lead screw 8. The movable seat 10 is slidably connected to the outer surface of the guide rods 7, and the lead screw 8 drives the movable seat 10 to move up and down through threaded transmission. A cleaning roller 11 is rotatably connected between two movable seats 10. Several evenly distributed cleaning heads 12 are fixedly connected to the outer surface of the cleaning roller 11. Two drive motors 9 rotate synchronously through a PLC controller, thereby driving the lead screw 8 to rotate synchronously. The cleaning roller 11 moves up and down under the drive of the lead screw 8 and the guidance of the guide rod 7, thereby driving the cleaning roller 11 and the cleaning head 12 to move synchronously.

[0018] Furthermore, a collection trough 13 is provided on the bottom inner wall of the dissolving tank 1 on the left side of the frame 5. A collection basket 14 is movably inserted into the collection trough 13. Connecting rods 15 are fixedly connected to both the front and rear ends of the collection basket 14. A pull rod 17 is fixedly connected between the two connecting rods 15. The collection basket 14 is used to hold the impurities cleaned from the filter screen 6. The impurities fall into the collection basket 14 and are taken out from the collection trough 13 by the pull rod 17 for impurity cleaning.

[0019] Furthermore, a cleaning port 19 is provided through the upper surface of the dissolving tank 1 at the corresponding position of the collection basket 14. A sealing cover 20 is connected between the inner walls of the front and rear sides of the cleaning port 19. A pull block 21 is fixedly connected to the sealing cover 20. When the collection basket 14 is not being cleaned, the sealing cover 20 is closed on the cleaning port 19 to prevent the solution from splashing out. When cleaning is required, the pull block 21 is held and pulled to rotate the sealing cover 20, thereby opening or closing the cleaning port 19.

[0020] Furthermore, the left end of the dissolving tank 1 is connected to the inlet 2, and the right end of the dissolving tank 1 is connected to the outlet 4. The inlet 2 is equipped with a shut-off valve 3. When the shut-off valve 3 is opened, the material is introduced into the dissolving tank 1 through the inlet 2. After the feeding is completed, the channel can be closed in conjunction with the shut-off valve 3.

[0021] Furthermore, a filter screen 6 is fixedly connected to the inner side of the frame 5. Several filter holes are opened through the surface of the filter screen 6. The filter holes are inserted and matched with the cleaning head 12. The filter screen 6 is used to filter large impurities or particles that have not been dissolved during the dissolution process, preventing them from entering the subsequent process and causing blockage. After the filter screen 6 intercepts large impurities or particles, the cleaning head 12 is inserted into the filter hole as the cleaning roller 11 moves and rotates, pushing out the impurities that are blocking the filter hole. There is no hard contact with the filter screen 6, thus achieving anti-clogging cleaning of the filter screen 6 and avoiding damage to the filter screen 6 caused by the traditional knocking method.

[0022] Furthermore, the inner walls on both the front and rear sides of the dissolving tank 1 are provided with grooves 18 on the left side of the frame 5. Slider 16 is fixedly connected to the opposite side of the two connecting rods 15. The slider 16 is slidably connected to the inside of the groove 18. The slider 16 slides along the groove 18 to provide guidance for the up and down movement of the collection basket 14, ensuring that the collection basket 14 can be smoothly taken out or put in.

[0023] Working principle: When using this utility model, first connect the external power supply of the device, open the shut-off valve 3, and add polyaluminum chloride raw material and appropriate amount of solvent into the dissolving tank 1 through the feed port 2. After the feeding is completed, close the shut-off valve 3. The material dissolves in the dissolving tank 1. During the process, start the drive motor 9. The drive motor 9 drives the lead screw 8 to rotate. The moving seat 10 moves up and down along the guide rod 7 under the action of the thread. The cleaning roller 11 moves with the moving seat 10. The cleaning head 12 is inserted into the filter hole of the filter screen 6 and pushes the blockage to the left. The impurities fall into the collection basket 14. After the dissolution is completed, open the discharge port 4. The filtered solution is discharged through the discharge port 4 and enters the subsequent processing stage. When there are many impurities in the collection basket 14, open the sealing cover 20 by pulling the pull block 21, hold the pull rod 17 and pull it up. The slider 16 slides along the slide groove 18 to take the collection basket 14 out from the cleaning port 19. After cleaning the impurities, put it back into the collection tank 13 and close the sealing cover 20.
