Description

Technical Field

[0001] The utility model belongs to the technical field of filtering equipment, and particularly relates to a filtering device for aluminum sulfate solution. Background Art

[0002] During the production of aluminum sulfate solution in the existing workshop, due to trace amounts of non-reactive impurities in the raw materials, or due to production fluctuations resulting in some aluminum hydroxide not reacting with concentrated sulfuric acid, fine particulate impurities will be contained in the aluminum sulfate solution. After sedimentation, there will still be a small amount of suspended particulate matter. After the product is input into the storage tank or filled into a closed container for storage, it is extremely easy to form precipitates or hydrolyzates with the suspended impurities as crystal nuclei, which has a great impact on the product quality. Therefore, it is necessary to filter the solution.

[0003] The existing filtering device for aluminum sulfate solution directly uses filter rods to filter the solution. As impurities accumulate, the passing rate of the solution through the filter rods becomes lower. At this time, it is necessary to stop the machine to replace the filter rods, which affects the filtering efficiency. At the same time, the solution needs a certain driving force to pass through the filter rods. Relying only on the fluidity of water to flow through the filter rods will affect the discharge efficiency of the solution, and thus affect the overall processing efficiency. And relying on components such as water pumps to pressurize the flow of the solution is difficult to ensure that the impurities in the solution will not block the power components. Summary of the Utility Model

The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0021] An embodiment of the present utility model provides a filter device for aluminum sulfate solution, as shown in Figures 1-4As shown in the figure, the aluminum sulfate solution filtering device includes: a storage tank 1 for storing the filtered aluminum sulfate solution; a support frame 2 installed on the top of the storage tank 1; a buffer hopper 3 for temporarily storing the unfiltered aluminum sulfate solution; two connecting pipes 4, both of the two connecting pipes 4 are installed at the bottom of the buffer hopper 3, and threaded blocks 5 are installed at the bottoms of the two connecting pipes 4; two filter cartridges 6, the two filter cartridges 6 are respectively threadedly installed on the two threaded blocks 5, the filter cartridge 6 is used to filter impurities in the aluminum sulfate solution, and hoses 7 extending into the storage tank 1 are rotatably installed at the bottoms of the two filter cartridges 6; an adjusting assembly, the adjusting assembly is arranged on the storage tank 1 and is used to adjust the air pressure in the storage tank 1.

[0022] In this embodiment, the storage tank 1 not only collects and stores the pure aluminum sulfate solution after filtration treatment, but also provides a stable support foundation for the entire device through its structural design. The buffer hopper 3 is used to temporarily store the unfiltered aluminum sulfate solution, increasing the stability of the solution flowing into the filter cartridge 6, thereby reducing the pressure on the filtration system. The buffer hopper 3 also facilitates the centralized delivery of the solution, improving the operation efficiency. The connecting pipe 4 and the threaded block 5 cooperate with each other to achieve the quick connection and disassembly between the buffer hopper 3 and the filter cartridge 6. The connecting pipe 4 ensures that the aluminum sulfate solution can flow smoothly from the buffer hopper 3 into the filter cartridge 6, while the threaded block 5 makes the installation and replacement of the filter cartridge 6 more convenient and fast through the threaded connection method, improving the flexibility and maintenance efficiency of the device. The hose 7 is rotatably installed at the bottom of the filter cartridge 6. This design enables the filter cartridge 6 to flexibly adjust the angle during the filtration process to meet different working requirements, and at the same time, the hose 7 ensures that the solution can flow smoothly into the storage tank 1.

[0023] In a further preferred embodiment of the present invention, the adjusting assembly includes a vacuum pump 10 and a partition plate 11. The vacuum pump 10 is installed on the top of the storage tank 1, the intake end of the vacuum pump 10 extends into the storage tank 1, the partition plate 11 is installed in the storage tank 1, the partition plate 11 is sleeved outside the liquid discharge end of the vacuum pump 10, and the partition plate 11 is used to isolate the splashing aluminum sulfate solution.

[0024] In this embodiment, the vacuum pump 10 can directly act on the space inside the storage tank 1, adjust the air pressure inside the storage tank 1 by generating negative pressure, and enable the solution to pass through the filter cartridge 6 faster, thereby improving the filtration efficiency and maintaining the stability of the system. Usually, the vacuum pump 10 does not directly drain liquid. The liquid is prevented from entering the pump body by the partition plate 11. The main function of the partition plate 11 is to isolate the aluminum sulfate solution that may splash due to improper operation or equipment failure. The aluminum sulfate solution has certain corrosiveness. If it directly contacts the vacuum pump 10 or other sensitive components, it may cause damage or safety hazards. Therefore, the existence of the partition plate 11 provides an additional protective barrier for the entire system, enhancing the safety and durability of the equipment.

[0025] In a further preferred embodiment of the present invention, filter cloths 8 for filtering impurities are laid in both filter cartridges 6. Plastic brackets 9 are placed in both filter cartridges 6. The two plastic brackets 9 are respectively in contact with the two filter cloths 8. The plastic brackets 9 are used to support the filter cloths 8, and the plastic brackets 9 have elasticity.

[0026] In this embodiment, the filter cloth 8 is a key filtering medium inside the filter cartridge 6. Its material and design can effectively intercept impurities and particulate matters in the aluminum sulfate solution, ensuring the purity of the output solution. The main function of the plastic bracket 9 is to support the filter cloth 8, preventing it from deforming or breaking due to solution pressure or impurity accumulation during the filtration process. At the same time, the elastic design of the plastic bracket 9 enables it to adapt to the minor deformations of the filter cloth 8 during the filtration process, maintaining the stability and filtration effect of the filter cloth 8.

[0027] In a further preferred embodiment of the present invention, a drain pipe 12 is provided on one side of the storage tank 1. Valves 14 are installed on the drain pipe 12 and the two connecting pipes 4. An observation window 13 is provided on one side of the storage tank 1.

[0028] In this embodiment, through the drain pipe 12, users can easily export the filtered and stored aluminum sulfate solution for subsequent use or treatment. This design not only improves the flexibility of solution management but also avoids the risk of solution splashing or contamination caused by directly opening the top cover of the storage tank 1. The valve 14 is used to control the on-off of each pipeline. By adjusting the opening and closing state of the valve 14, users can precisely control the flow path of the aluminum sulfate solution, ensuring the smooth progress of the filtration process and the safe storage of the solution in the storage tank 1. Through the observation window 13, users can clearly see information such as the liquid level, color, and state of the aluminum sulfate solution in the storage tank 1, thereby timely judging the filtration effect, storage volume, and whether the solution needs to be discharged, etc.

[0029] In a further preferred embodiment of the present utility model, a plurality of ventilation holes 15 are provided at the top of the storage box 1. A rubber protective sleeve 19 and a spring 16 sleeved outside the plurality of ventilation holes 15 are installed on the top of the storage box 1. The spring 16 is located inside the rubber protective sleeve 19. An installation plate 17 is installed at the top of the spring 16. The installation plate 17 is fixedly connected to the rubber protective sleeve 19. A trigger button 18 is provided at the top of the installation plate 17. A trigger plate 21 that can come into contact with the trigger button 18 is installed on the support frame 2.

[0030] In this embodiment, the softness and elasticity of the rubber protective sleeve 19 can effectively prevent external impurities from entering the ventilation holes 15, while ensuring the smoothness of the ventilation holes 15. When the air pressure in the storage box 1 is relatively low, the rubber protective sleeve 19 is in a compressed state to realize the monitoring of the air pressure. Due to the elastic effect of the spring 16, the trigger button 18 can come into contact with the trigger plate 21 when the air pressure is relatively high. The installation plate 17 not only provides an installation basis for the trigger button 18, but also transmits the elastic force of the spring 16 to the rubber protective sleeve 19 through its structural design, realizing the adjustment function of the ventilation holes 15.

[0031] In a further preferred embodiment of the present utility model, a limit telescopic rod 20 is provided inside the spring 16. The limit telescopic rod 20 is fixed between the installation plate 17 and the storage box 1. A shock pad is installed at the bottom of the trigger plate 21.

[0032] In this embodiment, the main function of the limit telescopic rod 20 is to limit the deformation range of the spring 16 during the telescopic process, preventing it from being damaged or failing due to excessive telescoping. By ensuring that the spring 16 works within a predetermined stroke, the limit telescopic rod 20 improves the stability and reliability of the entire ventilation hole 15 adjustment mechanism. At the same time, it also helps to maintain the precise alignment between the trigger button 18 and the trigger plate 21, ensuring the accuracy of automatic control. The shock pad can effectively absorb and disperse the impact force, reduce noise and vibration, and protect the trigger plate 21 and its related components from damage.

[0033] In a further preferred embodiment of the present utility model, a separation net 22 is installed in the buffer hopper 3. The separation net 22 is used to prevent the splashing of the aluminum sulfate solution. A support ring is installed on the separation net 22. The support ring is in contact with the inner wall of the buffer hopper 3.

[0034] In this embodiment, the main function of the isolation net 22 is to prevent the splashing of the aluminum sulfate solution during filtration or flow due to the impact force or vortex effect. The isolation net 22 can intercept and disperse these splashing droplets, making them converge again and flow in a predetermined direction, thus maintaining the cleanliness and orderliness of the internal environment of the buffer hopper 3. The main function of the support ring is to support and fix the isolation net 22 to prevent it from loosening or deforming due to uneven force or vibration during operation. By ensuring the close fit and stable connection between the isolation net 22 and the inner wall of the buffer hopper 3, the support ring improves the reliability and durability of the entire protective structure.

[0035] In summary, compared with the related art, by setting two filter cartridges 6 in this device, the filtration work can be continuously carried out when cleaning one of the filter cartridges 6, ensuring the processing efficiency. By setting the vacuum pump 10 to reduce the air pressure in the storage tank 1, the solution can pass through the filter cloth 8 and enter the storage tank 1 faster, increasing the filtration efficiency. By setting the spring 16, the mounting plate 17, the trigger button 18 and the rubber protective sleeve 19, the air pressure in the storage tank 1 can be monitored, facilitating timely processing and adjustment. The buffer hopper 3 can cache the aluminum sulfate solution to ensure the coherence of the solution entering the filter cartridge 6, thus facilitating the adjustment of the air pressure in the storage tank 1.
