Description

Technical Field

[0001] This utility model relates to the field of papermaking wastewater sedimentation technology, specifically a papermaking wastewater sedimentation and recovery device. Background Technology

[0002] In the process of paper production, a large amount of wastewater is generated. In addition to harmful chemical inorganic substances, the wastewater discharged by paper mills also contains volatile phenols, precipitated solids, suspended solids, lignin and other organic substances. The wastewater is then precipitated, and after the pulp settles, the wastewater is discharged and the pulp is recycled. A search revealed CN220385876U, which discloses a papermaking wastewater sedimentation and recovery device. The device involves starting a drive motor, which rotates a stirring rod. The stirring rod then rotates two vortex fan blades to efficiently mix wastewater, coagulant, and disinfectant, promoting sedimentation while simultaneously disinfecting. However, during mixing, impurities in the wastewater and coagulant adhere to the tank. Furthermore, the device rotates only in one direction, resulting in insufficient mixing of the wastewater and coagulant, which is inconvenient. Therefore, we propose a papermaking wastewater sedimentation and recovery device. Utility Model Content

[0003] The purpose of this invention is to provide a sedimentation and recycling device for papermaking wastewater.

[0004] To address the problems mentioned in the background art, this utility model provides the following technical solution: a papermaking wastewater sedimentation and recovery device, comprising a sedimentation tank, a plurality of bottom blocks fixed at the lower end of the sedimentation tank, a control plate provided at one end of the bottom blocks, a feed pipe fixed at the upper side of one side of the sedimentation tank, an mounting plate fixed at the center of the upper end of the sedimentation tank, a stepper motor provided at the upper end of the mounting plate, a pulley installed at the lower end of the stepper motor, a rotating groove opened on one side of the upper end of the sedimentation tank, a rotating cylinder rotatably arranged inside the rotating groove, a screw provided inside the rotating cylinder, a scraper fixed at the lower end of the screw, a sliding column fixed at one side of the upper end of the scraper, a limit plate fixed at the upper end of both the screw and the sliding column, a mixing column fixed at the lower end of the pulley, and a plurality of mixing blades fixed on the side wall of the mixing column.

[0005] Preferably, the pulley is rotatably connected to the rotating drum via a transmission belt, and both the mixing column and the mixing blade are located inside the sedimentation tank.

[0006] Preferably, the scraper is located inside the sedimentation tank and is slidably connected to the sedimentation tank.

[0007] Preferably, one end of the sliding column passes through the sedimentation tank and is fixedly connected to one end of the limiting plate, and the sliding column is slidably connected to the sedimentation tank.

[0008] Preferably, a filter plate and a collection box are respectively installed through the other side of the sedimentation tank. Multiple sets of fixing blocks are fixed at both ends of the sedimentation tank near the other side. A sliding rod is fixed at one end of each fixing block. A first moving plate and a second moving plate are respectively installed at both ends of the sliding rod. An insert block is fixed at one end of each of the first and second moving plates. Springs are provided at both ends of the lower end of the first moving plate.

[0009] Preferably, the filter plate and the collection box are both slidably connected to the sedimentation tank, and the spring is located between the first moving plate and the second moving plate.

[0010] Preferably, the slide bar passes through the first movable plate and the second movable plate, and both the first movable plate and the second movable plate are slidably connected to the slide bar.

[0011] Using the above technical solution, through the cooperation of stepper motor and pulley, the mixing column drives the mixing blade to mix the wastewater and sediment inside the sedimentation tank, and the transmission belt drives the rotating drum to rotate inside the rotating trough, so that the screw can scrape the inner wall of the sedimentation tank through the scraper. Then, through the cooperation of the limiting plate, the scraper will not collide with the filter plate during scraping. This allows the papermaking wastewater sedimentation and recovery device to mix the wastewater and coagulant inside the sedimentation tank, and to scrape off the impurities and coagulant adhering to the inner wall of the sedimentation tank during the mixing process. By adopting the above technical solution, the filter plate can be quickly loaded and unloaded through the insertion block by the cooperation of the first moving plate, the slide rod and the spring, which facilitates the loading and unloading of the filter plate. Then, with the cooperation of the second moving plate, the slide rod and the spring, the collection box can be quickly loaded and unloaded, which facilitates the collection of sediment inside the collection box. This allows the papermaking wastewater sedimentation and recovery device to quickly load and unload the filter plate and the collection box, which facilitates the replacement of the filter plate and the collection of sediment inside the collection box.

[0014] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0015] Example 1: Please see Figure 1-4 This utility model provides a technical solution: a papermaking wastewater sedimentation and recovery device, including a sedimentation tank 1. Multiple sets of bottom blocks 2 are fixed to the lower end of the sedimentation tank 1. A control plate 3 is installed at one end of each bottom block 2. A feed pipe 4 is fixed to one side of the sedimentation tank 1 near the upper side. An mounting plate 5 is fixed to the center of the upper end of the sedimentation tank 1. A stepper motor 6 is installed at the upper end of the mounting plate 5. A pulley 7 is installed at the lower end of the stepper motor 6. A rotating groove 8 is opened on one side of the upper end of the sedimentation tank 1. A rotating cylinder 9 is rotatably installed inside the rotating groove 8. A screw 11 is installed inside the rotating cylinder 9. A scraper is fixed to the lower end of the screw 11. A sliding column 15 is fixed to one side of the upper end of the plate 12 and scraper 12. A limiting disk 16 is fixed to the upper end of both the screw 11 and the sliding column 15. A mixing column 13 is fixed to the lower end of the pulley 7. Multiple sets of mixing blades 14 are fixed to the side walls of the mixing column 13. The pulley 7 is rotatably connected to the drum 9 through the transmission belt 10. The mixing column 13 and the mixing blades 14 are both located inside the sedimentation tank 1. The scraper 12 is located inside the sedimentation tank 1 and is slidably connected to the sedimentation tank 1. One end of the sliding column 15 passes through the sedimentation tank 1 and is fixedly connected to one end of the limiting disk 16. The sliding column 15 is slidably connected to the sedimentation tank 1.

[0016] Specifically, wastewater and coagulant are discharged into sedimentation tank 1 through feed pipe 4. Then, stepper motor 6 is started by control board 3, causing pulley 7 to rotate clockwise. At this time, pulley 7 drives mixing column 13 to rotate. Then, mixing blades 14 on the side wall of mixing column 13 mix the wastewater and coagulant inside sedimentation tank 1. Simultaneously, as pulley 7 rotates, it drives rotating drum 9 to rotate inside rotating trough 8 via transmission belt 10. When rotating drum 9 rotates, it drives internal screw 11 to move upward, and scraper 12 will... The screw 11 moves together with the slide column 15 and slides on the sedimentation tank 1. As the scraper 12 moves, it scrapes off the impurities attached to the inner wall of the sedimentation tank 1. When the scraper 12 moves to the top of the sedimentation tank 1, the stepper motor 6 drives the pulley 7 to rotate in the opposite direction, causing the scraper 12 to move downward and scrape off the inner wall of the sedimentation tank 1 again. This process is repeated so that the papermaking wastewater sedimentation and recovery device can mix the wastewater and coagulant inside the sedimentation tank 1 and scrape off the impurities and coagulant attached to the inner wall of the sedimentation tank 1 during the mixing process.

[0017] Example 2: Please see Figure 1-4 This utility model provides a technical solution: a papermaking wastewater sedimentation and recovery device, wherein a filter plate 17 and a collection box 18 are respectively installed through the other side of the sedimentation tank 1, and multiple sets of fixing blocks 19 are fixed at both ends of the sedimentation tank 1 near the other side. A sliding rod 20 is fixed at one end of the fixing block 19, and a first moving plate 21 and a second moving plate 22 are respectively installed at both ends of the sliding rod 20. An insert block 23 is fixed at one end of the first moving plate 21 and the second moving plate 22, and springs 24 are provided at both ends of the lower end of the first moving plate 21. The filter plate 17 and the collection box 18 are slidably connected to the sedimentation tank 1, and the springs 24 are located between the first moving plate 21 and the second moving plate 22. The sliding rod 20 passes through the first moving plate 21 and the second moving plate 22, and the first moving plate 21 and the second moving plate 22 are slidably connected to the sliding rod 20.

[0018] Specifically, when the filter plate 17 needs to be replaced, pressing the first moving plate 21 causes it to slide on the slide rod 20. This compresses the spring 24, causing the upper insert block 23 to move and slide out of the filter plate 17, thus removing the fixation between the sedimentation tank 1 and the filter plate 17. Then, pulling the filter plate 17 slides it out of the sedimentation tank 1, and inserting the replacement filter plate 17 into the sedimentation tank 1. Releasing the first moving plate 21 allows it to push the insert block 23 back to its original position under the elasticity of the spring 24, thus fixing the filter plate 17 in place. When it is necessary to recover the sediment inside the collection tank 18, the control plate 3 is activated. The pump 25 is activated to discharge the wastewater from the sedimentation tank 1 through the drain pipe 26. After discharge, the second moving plate 22 is pulled to compress the spring 24 and pull the lower insert 23 out of the collection box 18. The collection box 18 is then pulled out, and the sediment inside is collected. The collection box 18 is then returned to its original position, and the second moving plate 22 is released. Under the elasticity of the spring 24, the second moving plate 22 pushes the insert 23 back to its original position, fixing the collection box 18 to the sedimentation tank 1 again. This allows the papermaking wastewater sedimentation and recovery device to quickly install and remove the filter plate 17 and the collection box 18, facilitating the replacement of the filter plate 17 and the collection of sediment inside the collection box 18.

For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
