Description

Technical Field

[0001] This utility model relates to the field of PP tank technology, and in particular to a corrosion-resistant PP tank. Background Technology

[0002] PP pickling tanks are made of polypropylene sheets and are used for filtering, cleaning, or soaking corrosive materials such as hydrochloric acid. They can be used for cleaning or soaking instruments in chemical, medical, teaching, and research units and laboratories.

[0003] During use, filters trap a large number of impurities. Over time, these impurities accumulate on the filters. Since they cannot be disassembled, they cannot be removed for thorough cleaning. They can only be cleaned by simple rinsing, which is insufficient to completely remove the dirt from the pores and surface of the filters. This leads to a gradual decrease in the filtering effect of the filters. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a corrosion-resistant PP tank. When a button is pressed, the limiting plate is disengaged from the fixed box. During disengagement, the sliding plate is pulled to move the sliding box, allowing the filter screen to be replaced while the sliding box is moving. This effectively removes accumulated impurities, dirt, and microorganisms, restoring the filter screen's filtration performance.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A corrosion-resistant PP tank includes: a tank body serving as the storage body; an infusion tube fixedly connected to the left end of the tank body; a fixed box fixedly connected to the inner wall of the infusion tube; a sliding plate slidably connected to the inner wall of the fixed box; limit plates slidably connected to both sides of the inner wall of the sliding plate; insert blocks fixedly connected to opposite ends of the limit plates; a first spring provided between the inner walls of the sliding plate and the limit plates; a sliding box fixedly connected to the bottom end of the sliding plate; a filter screen slidably connected to the inner wall of the sliding box; connecting frames fixedly connected to both sides of the outer wall of the fixed box; a fixed cylinder fixedly connected to the inner wall of each connecting frame; a movable plate slidably connected to the inner wall of each fixed cylinder; a button fixedly connected to the inner wall of each movable plate; a second spring provided between the inner walls of the fixed cylinder and the movable plate; and a partition assembly provided on the inner wall of the tank body.

[0007] Furthermore, one end of each of the first springs is connected to the limiting plate, and the other end of each of the first springs is connected to the inner wall of the slide plate.

[0008] Furthermore, one end of each of the second springs is connected to the movable plate, and the other end of each of the second springs is connected to the inner wall of the fixed cylinder.

[0009] Furthermore, a feed pipe is fixedly connected to the bottom end of the tank.

[0010] Furthermore, the separating component includes connecting boxes fixedly connected to both sides of the inner wall of the tank, with baffles slidably connected to the inner walls of the connecting boxes, and fixing frames fixedly connected to both sides of the outer wall of the tank. Pull rods are slidably connected to the inner walls of the fixing frames, and fixing plates are fixedly connected to the outer walls of the pull rods. A third spring is provided between the fixing plate and the inner wall of the fixing frame.

[0011] Furthermore, the inner wall of the baffle is provided with multiple fixing holes corresponding to the tie rod.

[0012] Furthermore, one end of each of the third springs is connected to the fixed plate, and the other end of each of the third springs is connected to the inner wall of the fixed frame.

Detailed Implementation

[0024] 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.

[0025] Reference Figures 1-3 This utility model provides an embodiment of a corrosion-resistant PP tank, comprising: a tank body 1 serving as the storage body; an infusion tube 2 fixedly connected to the left end of the tank body 1; a fixing box 3 fixedly connected to the inner wall of the infusion tube 2; a sliding plate 4 slidably connected to the inner wall of the fixing box 3; limit plates 5 slidably connected to both sides of the inner wall of the sliding plate 4; insert blocks 6 fixedly connected to opposite ends of the limit plates 5; a first spring 7 provided between the inner walls of the sliding plate 4 and the limit plates 5; a sliding box 8 fixedly connected to the bottom end of the sliding plate 4; a filter screen 9 slidably connected to the inner wall of the sliding box 8; and connecting brackets 10 fixedly connected to both sides of the outer wall of the fixing box 3. The inner wall of the connecting frame 10 is fixedly connected to a fixed cylinder 11, the inner wall of the fixed cylinder 11 is slidably connected to a moving plate 12, the inner wall of the moving plate 12 is fixedly connected to a button 13, a second spring 14 is provided between the inner walls of the fixed cylinder 11 and the moving plate 12, the inner wall of the trough 1 is provided with a partition component, one end of the first spring 7 is connected to the limiting plate 5, the other end of the first spring 7 is connected to the inner wall of the slide plate 4, one end of the second spring 14 is connected to the moving plate 12, the other end of the second spring 14 is connected to the inner wall of the fixed cylinder 11, and the bottom end of the trough 1 is fixedly connected to a discharge pipe 22.

[0026] Specifically, when it is necessary to disassemble the filter screen 9, press button 13. After button 13 is pressed, it will cause the limiting plate 5 to detach from the fixed box 3. At this time, pull the sliding plate 4. The sliding plate 4 will move the sliding box 8. After the sliding box 8 moves, the filter screen 9 can be replaced. This can effectively remove the impurities, dirt and microorganisms accumulated on the filter screen 9, allowing the filter screen 9 to restore good filtration performance. To install the filter screen 9, insert the sliding plate 4 into the fixed box 3. At this time, the first spring 7 will generate elastic force to push the limiting plate 5. When the limiting plate 5 moves, it will drive the insert block 6 to insert into the inner wall of the fixed box 3, thereby realizing the fixed installation of the filter screen 9. This PP tank is made of polypropylene material. Polypropylene has excellent chemical stability and can resist most corrosive substances such as acids, alkalis and salts. Therefore, this PP tank can be used for long-term storage and treatment of various corrosive liquids and is not easily corroded and damaged, ensuring its reliable use in corrosive environments such as chemical and electroplating industries.

[0027] Reference Figures 4-6 The partition assembly includes a connecting box 15 fixedly connected to both sides of the inner wall of the tank 1. The inner wall of the connecting box 15 is slidably connected to a baffle 16. The outer wall of the tank 1 is fixedly connected to both sides of a fixing frame 17. The inner wall of the fixing frame 17 is slidably connected to a pull rod 18. The outer wall of the pull rod 18 is fixedly connected to a fixing plate 19. A third spring 20 is provided between the fixing plate 19 and the inner wall of the fixing frame 17. The inner wall of the baffle 16 is provided with multiple fixing holes 21 corresponding to the pull rod 18. One end of the third spring 20 is connected to the fixing plate 19, and the other end of the third spring 20 is connected to the inner wall of the fixing frame 17.

[0028] Specifically, when it is necessary to divide the interior of the corrosion-resistant PP tank, the liquid is slowly injected from the infusion pipe 2. During the injection process, the filter screen 9 performs its filtering function, intercepting impurities in the liquid and ensuring that the liquid flowing into the tank 1 is pure. After the liquid injection is completed, the pull rod 18 is pulled to precisely insert the baffle 16 into the connecting box 15. Then the pull rod 18 is released. At this time, the third spring 20 immediately releases its elastic force, pushing the fixing plate 19 forward. The movement of the fixing plate 19 drives the pull rod 18 to move in tandem, thereby embedding the fixing plate 19 into the fixing hole 21 for firm fixation. Through this operation, the internal space of the tank 1 can be flexibly divided according to the material characteristics or process flow, significantly improving management efficiency. When it is necessary to discharge the liquid, the baffle 16 is first pulled out, and then the control valve on the discharge pipe 22 is opened, and the liquid can flow out smoothly from the discharge pipe 22.

[0029] Working principle: First, when internal separation is needed, liquid is injected through the infusion pipe 2. During injection, the filter screen 9 filters the liquid, and the filtered liquid flows into the tank 1. At this time, the pull rod 18 is pulled, and the baffle 16 is inserted into the connecting box 15. Then, the pull rod 18 is released. When the pull rod 18 is released, the third spring 20 will spring the fixing plate 19. When the fixing plate 19 is springed, it drives the pull rod 18 to move. When the pull rod 18 moves, it drives the fixing plate 19 to move. When the fixing plate 19 moves, it is inserted into the fixing hole 21 for fixation. This allows for separation according to the material properties or processing flow, improving management efficiency. When liquid needs to be discharged, the baffle 16 is removed, and then the control valve on the discharge pipe 22 is opened to allow the liquid to flow out. To disassemble filter 9, press button 13. When button 13 is pressed, the limiting plate 5 is disengaged from the inside of the fixing box 3. When disengaged, the sliding plate 4 is pulled to move the sliding box 8. When the sliding box 8 moves, filter 9 is replaced, thereby effectively removing accumulated impurities, dirt and microorganisms, and restoring the filtration performance of filter 9. When installation is required, insert the sliding plate 4 into the fixing box 3. At this time, the first spring 7 will spring the limiting plate 5. When the limiting plate 5 is springed, the insert block 6 is inserted into the inner wall of the fixing box 3 for fixation. PP tank is made of polypropylene material. Polypropylene has excellent chemical stability and good resistance to most corrosive substances such as acids, alkalis and salts. It can store and handle various corrosive liquids for a long time and is not easily corroded and damaged, ensuring the reliable use of PP tank in corrosive environments such as chemical industry and electroplating.
