[0002] Chemical raw materials are raw materials produced using chemical methods. They include inorganic chemical products other than fertilizers, inorganic pesticides, and inorganic pigments, as well as various products mainly manufactured using polymer materials in the organic synthesis industry. During the reaction and processing of chemical liquid raw materials, it is necessary to store the chemical liquid raw materials through some storage devices.

[0003] A search revealed a Chinese patent publication number CN209225852U, which discloses a corrosion-resistant chemical raw material storage device, including a storage tank, a tank cover, a cooling fan, and a pressure relief unit. The pressure relief unit includes a fixed plug, a sliding plug, and a spring.

[0004] This patented technology uses a silica layer to make the storage tank less susceptible to corrosion when storing chemical raw materials due to the inertness of silica in chemical reactions, thus improving the corrosion resistance of the storage tank. However, it cannot clean the chemical raw materials adhering to the inner wall of the storage tank, resulting in waste. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a leak-proof storage device for liquid chemical raw materials.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A leak-proof storage device for liquid chemical raw materials includes a tank body. A tank cover is bolted to the top of the tank body. A drive assembly is installed on the top of the inner wall of the tank cover. Multiple scrapers are connected to the bottom of the drive assembly via a connecting frame. One end of each scraper is inclined downwards, and the outer wall of the scraper contacts the inner wall of the tank body. The drive assembly includes multiple telescopic cylinders and a folding airbag. The multiple telescopic cylinders are interconnected via two sliding grooves and guide blocks.

[0008] As a further improvement of this utility model: a sealing ring is provided at the adjacent end of the can lid and the can body, and the sealing rings on the can lid and the can body are engaged with each other.

[0009] As a further embodiment of this utility model: two grooves are opened in parallel on the outer wall of the telescopic cylinder, and the groove trajectory is spiral. Two guide blocks are fixed relative to each other at the top of the inner wall of the telescopic cylinder, and the guide blocks slide in cooperation with the inner wall of the groove.

[0010] As a further embodiment of this utility model: the connecting frame and the scraper are connected by a connecting assembly, the connecting assembly including a cavity and a plug rod, the cavity being opened at one end of the connecting frame, and the plug rod being connected to one end of the scraper.

[0015] Compared with the prior art, the present invention provides a leak-proof storage device for liquid chemical raw materials, which has the following beneficial effects:

[0016] This invention comprises a drive assembly, a connecting frame, a scraper, an air pump, and an exhaust valve. The air pump inflates the folding airbag, propelling the telescopic cylinder downwards and causing it to rotate. This allows the scraper to clean the inner wall of the tank, reducing the adhesion of chemical materials. Furthermore, the invention includes a sliding groove and a guide block.

[0026] Example 1

[0027] A leak-proof storage device for liquid chemical raw materials, such as Figures 1 to 4As shown, the device includes a tank body 1, with a tank cover 2 bolted to the top of the tank body 1. A sealing ring 4 is provided at the end of the tank cover 2 adjacent to the tank body 1, and the sealing rings 4 on the tank cover 2 and the tank body 1 mesh with each other. A discharge port 3 is provided on the bottom side wall of the tank body 1. A drive assembly 5 is provided at the top of the inner wall of the tank cover 2. Multiple scrapers 7 are connected to the bottom of the drive assembly 5 via a connecting frame 6. One end of each scraper 7 is inclined downwards, and the outer wall of the scraper 7 contacts and engages with the inner wall of the tank body 1. The drive assembly 5 includes multiple telescopic cylinders 11 and folding airbags 12. The multiple telescopic cylinders 11 are interconnected via two sliding grooves 15 and guide blocks 16. The two sliding grooves 15 are parallel to each other on the outer wall of the telescopic cylinders 11. The slide groove 15 has a spiral trajectory. The two guide blocks 16 are fixed to the top of the inner wall of the telescopic cylinder 11. The guide blocks 16 slide in cooperation with the inner wall of the slide groove 15. The bottom end of the folded airbag 12 is connected to the bottom end of the inner wall of the outermost telescopic cylinder 11. The other end of the folded airbag 12 is connected to the inner wall of the top of the can lid 2. A tension spring 13 is fixed to the inner wall of the top of the can lid 2. The other end of the tension spring 13 is connected to the outermost telescopic cylinder 11. A fixing frame 8 is fixed to the outer wall of the top of the can lid 2. An air pump 9 is fixed to the outer wall of the top of the fixing frame 8. The output end of the air pump 9 is connected to the folded airbag 12 through a connecting pipe 14. An exhaust valve 10 is provided on one side of the outer wall of the connecting pipe 14.

[0028] During the discharge of chemical raw materials stored in tank 1 through outlet 3, air pump 9 inflates folded airbag 12 through connecting pipe 14, pushing telescopic cylinder 11 to move down layer by layer. Tension spring 13 is stretched, causing connecting frame 6 to drive scraper 7 to scrape the inner wall of tank 1 from top to bottom. At the same time, since the outer wall of telescopic cylinder 11 is provided with sliding groove 15, when telescopic cylinder 11 moves down, guide block 16 will drive telescopic cylinder 11 to rotate along sliding groove 15, causing scraper 7 to rotate, so that scraper 7 can clean the inner wall of tank 1 better. After cleaning stops, air pump 9 stops, exhaust valve 10 opens, tension spring 13 pulls telescopic cylinder 11 to reset, squeezes folded airbag 12, and causes gas inside folded airbag 12 to be discharged. The interlocking sealing ring 4 can seal the gap between tank cover 2 and tank body 1 after tank cover 2 and tank body 1 are closed, reducing the volatilization of chemical raw materials.

[0029] By setting up a drive assembly 5, a connecting frame 6, a scraper 7, an air pump 9, and an exhaust valve 10, the air pump 9 inflates the folded airbag 12, pushing the telescopic cylinder 11 to rotate downwards, so that the scraper 7 cleans the inner wall of the tank 1, reducing the adhesion of chemical raw materials to the inner wall of the tank 1.

[0030] By setting the chute 15 and guide block 16, when the telescopic cylinder 11 moves downward, the guide block 16 will drive the telescopic cylinder 11 to rotate along the chute 15, causing the scraper 7 to rotate, so that the scraper 7 can clean the inner wall of the tank 1 better.

[0031] Example 2

[0032] A leak-proof storage device for liquid chemical raw materials is provided in this embodiment, which is based on Embodiment 1 and makes the following improvements, such as... Figure 5 As shown, the connecting frame 6 and the scraper 7 are connected by a connecting assembly, which includes a cavity 17 and a rod 18. The cavity 17 is located at one end of the connecting frame 6, and the rod 18 is connected to one end of the scraper 7. The rod 18 is slidably connected to the cavity 17. Limiting cavities 19 are provided on both sides of the cavity 17. A limiting rod 20 is slidably connected to one end of the limiting cavity 19. A limiting hole is provided on the outer wall of the rod 18 to limit the limiting rod 20. An inclined block 21 is fixed on one side of the outer wall of the limiting rod 20. The limiting cavity 19 is located away from the limiting rod 20. A pull rod 22 is slidably connected to one end of the rod 20. The pull rod 22 is in sliding contact with the surface of the inclined block 21. A return spring 23 is fixed to the outer wall of one side of the pull rod 22. The other end of the return spring 23 is connected to the inner wall of the limiting cavity 19. A limiting spring 24 is fixed to the outer wall of one end of the limiting rod 20. The other end of the limiting spring 24 is connected to the limiting cavity 19. The limiting spring 24 and the return spring 23 are staggered. A sealing plate 25 is fixed to one side of the pull rod 22. A clearance groove is opened at one end of the limiting cavity 19 to slide with the sealing plate 25.

[0033] When the scraper 7 shows signs of wear and needs to be replaced, remove the tank cover 2, take the connecting frame 6 and scraper 7 out of the tank body 1, push the pull rod 22 to one side, compress the return spring 23, and through the pressure of the pull rod 22 on the inclined block 21, cause the limiting rod 20 to retract into the limiting cavity 19, compress the limiting spring 24, and at this time the restriction on the insertion rod 18 is released. Pull the insertion rod 18 out of the cavity 17, replace the scraper 7, and seal the limiting cavity 19 with the sealing plate 25 to reduce the entry of chemical raw material volatilized gas into the limiting cavity 19 during use.

[0034] By setting up a connecting component, pushing the pull rod 22 to one side can release the restriction on the insertion rod 18, making it easier to replace the scraper 7. The sealing plate 25 seals the limiting cavity 19, reducing the entry of chemical raw material volatilized gas into the limiting cavity 19 during use.

[0035] Working principle: During the discharge of chemical raw materials stored in tank 1 through outlet 3, air pump 9 inflates folded airbag 12 through connecting pipe 14, pushing telescopic cylinder 11 to move downwards layer by layer. Tension spring 13 stretches, causing connecting frame 6 to drive scraper 7 to scrape the inner wall of tank 1 from top to bottom. Simultaneously, because the outer wall of telescopic cylinder 11 is provided with a sliding groove 15, when telescopic cylinder 11 moves downwards, guide block 16 drives telescopic cylinder 11 to rotate along the sliding groove 15, causing scraper 7 to rotate, thus improving the cleaning effect of scraper 7 on the inner wall of tank 1. After cleaning stops, air pump 9 stops, exhaust valve 10 opens, tension spring 13 pulls telescopic cylinder 11 back to its original position, squeezing folded airbag 12, causing the gas inside folded airbag 12 to be discharged. The interlocking sealing rings 4 can seal the gap between the can lid 2 and the can body 1 after the can lid 2 and the can body 1 are combined, reducing the volatilization of chemical raw materials. When the scraper 7 is worn and needs to be replaced, the can lid 2 is removed, the connecting frame 6 and the scraper 7 are taken out of the can body 1, the pull rod 22 is pushed to one side, the return spring 23 is compressed, and the limit rod 20 is retracted into the limit cavity 19 by the pressure of the pull rod 22 on the inclined block 21. The limit spring 24 is compressed, and the restriction on the insertion rod 18 is released. The insertion rod 18 is pulled out from the cavity 17, the scraper 7 is replaced, and the sealing plate 25 seals the limit cavity 19 to reduce the entry of the volatilized gas of chemical raw materials into the limit cavity 19 during use.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
