Description

Technical Field

[0001] This utility model relates to the field of operational technology, and in particular to a separation device for aluminum ash pickling waste liquid. Background Technology

[0002] In the treatment of aluminum ash pickling waste liquid, pipeline filters are one of the key pieces of equipment for achieving solid-liquid separation and ensuring the stable operation of subsequent treatment stages. Aluminum ash pickling waste liquid contains a large amount of unreacted aluminum ash particles, metal oxides, and other solid impurities. These impurities can seriously affect subsequent chemical precipitation, ion exchange, and reverse osmosis processes, such as clogging pipelines, damaging equipment, and reducing treatment efficiency. Therefore, pre-treating the waste liquid with pipeline filters to remove solid impurities is crucial. Currently, most pipeline filters used for aluminum ash pickling waste liquid treatment on the market use traditional fixed installation methods for their filter elements. This installation method usually requires the use of wrenches, screwdrivers, and other tools to fix the filter element inside the filter body using bolts and flanges. When the filter element needs cleaning or replacement due to the trapping of a large amount of impurities, operators need to spend a lot of time and effort disassembling the filter housing and loosening bolts. The entire operation process is cumbersome and complex, not only reducing equipment maintenance efficiency but also increasing labor costs. Furthermore, improper operation or improper use of tools can easily lead to filter element damage or sealing component failure, resulting in waste liquid leakage. Utility Model Content

[0029] Please see Figure 1-4 This utility model provides a technical solution: an aluminum ash pickling waste liquid separation device, including a regulating tank 1, a pipeline filter body 4 and a reaction sedimentation tank 6;

[0030] A limit device is provided on the main body 4 of the pipeline filter;

[0031] The limiting device includes a mounting base 8, a filter element 13, and three protective shells 5. All three protective shells 5 are fixedly connected to the lower outer wall of the pipeline filter body 4. A mounting groove 17 is formed on the lower outer wall of the pipeline filter body 4, and the interior of the mounting groove 17 communicates with the interior of the pipeline filter body 4. The outer wall of the mounting base 8 is slidably connected to the interior of the mounting groove 17. Three second limiting block grooves 16 are formed inside the mounting groove 17, and limiting blocks 15 are slidably connected inside each of the three second limiting block grooves 16. The interiors of the three protective shells 5 communicate with the interiors of their respective second limiting block grooves 16. Three first limiting block grooves 14 are formed on the outer wall of the mounting base 8. The ends of the three limiting blocks 15 near the first limiting block grooves 14 slidably extend into the interior of the mounting groove 17 and are slidably connected to the interiors of their respective first limiting block grooves 14. The filter element 13 is fixedly mounted on the mounting base 8. On one end of the outer wall of the mounting base 8, the lower surface of the three protrusions at the lower end of the pipeline filter body 4 is provided with T-shaped block grooves 12. Three T-shaped blocks 9 are fixedly connected to the outer wall of the mounting base 8. The outer walls of the three T-shaped blocks 9 are slidably connected to the interior of the corresponding T-shaped block grooves 12. The outer walls of the three protective shells 5 are rotatably connected with rotating threaded rod sleeves 10. Rotating threaded rods 11 are provided inside the interior of the three second limit block grooves 16. The ends of the three rotating threaded rods 11 near the limit block 15 are rotatably connected to the ends of the corresponding limit blocks 15. The ends of the three rotating threaded rod sleeves 10 near the limit block 15 are rotatably extended into the interior of the second limit block grooves 16. The outer walls of the ends of the three rotating threaded rods 11 near the rotating threaded rod sleeves 10 are threadedly connected to the interior of the corresponding rotating threaded rod sleeves 10. The upper end of the pipeline filter body 4 is connected to the lower end of the regulating tank 1 through a flange.

[0032] The regulating tank 1 is rotatably connected to a stirring shaft 7. The reaction sedimentation tank 6 is connected to the outlet flange on the pipeline filter body 4 via a connecting pipe. A motor 3 is installed at the upper end of the regulating tank 1. The output end of the motor 3 extends rotatably into the interior of the regulating tank 1 and is fixedly connected to one end of the stirring shaft 7. A feed pipe 2 is installed at the upper end of the regulating tank 1. The interior of the feed pipe 2 is connected to the interior of the regulating tank 1. An outlet pipe is provided at the lower end of the pipeline filter body 4.

[0033] Furthermore, when using this device, it is started by connecting to an external power source. The aluminum ash pickling waste liquid first enters the regulating tank 1 through the feed pipe 2. The motor 3 starts, driving the stirring shaft 7 to rotate, thoroughly mixing the waste liquid to ensure uniform composition and provide good conditions for subsequent treatment. Then, the uniformly mixed waste liquid flows into the pipeline filter body 4 through the flange connection between the regulating tank 1 and the pipeline filter body 4. When installing the filter element 13, the mounting base 8 is slid into the mounting base groove 17, so that the T-block 9 is initially positioned by engaging with the T-block groove 12. Then, the rotating threaded rod sleeve 10 on the outer wall of the protective shell 5 is rotated. The rotating threaded rod sleeve 10 engages with the rotating threaded rod 11, pushing the limit block 15 towards the mounting base 8. Until the limiting block 15 slides into the first limiting block groove 14 and fixes the mounting base 8, the filter element 13 is installed. In this way, when the waste liquid passes through the filter element 13, the solid impurities in it are intercepted by the filter element 13, realizing the initial separation of solid and liquid. The waste liquid after initial filtration flows into the reaction sedimentation tank 6 through the liquid outlet pipe of the pipeline filter body 4. In the reaction sedimentation tank 6, the waste liquid undergoes further reaction and sedimentation, causing the remaining impurities to settle down, thereby completing the entire separation process of aluminum ash pickling waste liquid. Then, when it is necessary to replace the filter element 13, rotate the threaded rod sleeve 10 in the opposite direction to make the limiting block 15 exit from the first limiting block groove 14, releasing the limitation on the mounting base 8. Then slide the mounting base 8 out from the mounting base groove 17, and the filter element 13 can be taken out for replacement.

[0034] By rotating the threaded sleeve 10 in the limiting device, the limiting block 15 is disengaged from the first limiting block groove 14, releasing the limiting of the mounting seat 8. Then, the mounting seat 8 is slid out from the mounting seat groove 17, and the filter element 13 can be removed for replacement. This method of disassembling the filter element 13 is simple and quick, avoiding the need for workers to use tools to loosen bolts to disassemble the filter element 13, and effectively improving the maintenance and repair efficiency of the filter element 13.

[0035] Structural Description: Regulating Tank 1: Regulating Tank 1 is the starting point of the entire separation process. It is internally connected to a stirring shaft 7, and an electric motor 3 is installed at the upper end of the tank body. The output end of the electric motor 3 is connected to the stirring shaft 7. During operation, the electric motor 3 drives the stirring shaft 7 to rotate, which can fully stir and mix the aluminum ash pickling waste liquid entering the regulating tank 1 to ensure that the waste liquid composition is uniform. At the same time, the upper end of the regulating tank 1 is equipped with a feed pipe 2 to facilitate the entry of aluminum ash pickling waste liquid into the regulating tank 1, in preparation for subsequent treatment.

[0036] Pipeline filter body 4: Pipeline filter body 4 is the core component for achieving waste liquid filtration and separation. Three protective shells 5 are fixedly connected to its lower outer wall. An installation seat groove 17 is opened on the lower outer wall. The inside of the groove is connected to the inside of the pipeline filter body 4 and is used to install filter element 13 and related components. In addition, a discharge pipe is provided at the lower end of the pipeline filter body 4. The filtered waste liquid is discharged through the discharge pipe. The upper end is connected to the lower end of the regulating tank 1 through a flange to ensure that the uniformly stirred waste liquid in the regulating tank 1 can flow smoothly into the pipeline filter body 4.

[0037] Reaction sedimentation tank 6: The reaction sedimentation tank 6 is connected to the outlet pipe flange on the pipeline filter body 4 via a connecting pipe. It is used to receive the waste liquid filtered by the pipeline filter body 4 and to carry out reaction sedimentation to further separate impurities in the waste liquid.

[0038] Mounting seat 8: The outer wall of mounting seat 8 is slidably connected to the inside of mounting seat groove 17. One end of its outer wall is fixedly mounted with filter element 13, which is the bearing component of filter element 13. The filter element 13 can be installed and removed by sliding in the mounting seat groove 17. Three T-shaped blocks 9 are also fixedly connected to the outer wall of mounting seat 8, which cooperate with the T-shaped block groove 12 on the lower surface of the protrusion at the lower end of the pipeline filter body 4 to play a preliminary positioning role.

[0039] Filter element 13: Filter element 13 is installed on the mounting base 8 and is used to filter the waste liquid entering the pipeline filter body 4, intercept solid impurities in the waste liquid, and achieve preliminary solid-liquid separation;

[0040] Protective shell 5: Three protective shells 5 are located on the lower outer wall of the main body 4 of the pipeline filter. Their interiors are connected to the corresponding second limit block groove 16. They mainly serve to protect internal rotating threaded rods 11 and other components, and prevent external impurities from entering and affecting the normal operation of the limit device.

[0041] Limiting block 15: Three limiting blocks 15 are slidably connected in three second limiting block grooves 16 respectively, and one end can slide to the mounting seat groove 17 and slide to connect with the first limiting block groove 14 on the outer wall of the mounting seat 8. The movement of the limiting blocks 15 realizes the limiting and fixing of the mounting seat 8, ensuring that the filter element 13 is installed firmly.

[0042] Rotating threaded sleeve 10 and rotating threaded rod 11: Rotating threaded sleeve 10 is rotatably connected to the outer wall of protective shell 5. One end of rotating threaded rod 11 is rotatably connected to limiting block 15, and the other end is threadedly connected to rotating threaded sleeve 10. By rotating rotating threaded sleeve 10, rotating threaded rod 11 can be moved, thereby pushing limiting block 15 to slide in second limiting block groove 16, so as to limit or release the mounting seat 8.

[0043] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
