[0002] Liquid chlorine, also known as liquid chlorine, is a yellow-green liquid at room temperature. It has strong oxidizing and corrosive properties. Industrially, liquid chlorine is mainly used to produce chemical products such as hydrochloric acid, polyvinyl chloride, plastics, and pesticides. It is also an important raw material for industries such as metallurgy, textiles, and papermaking.

[0003] During the production and transportation of liquid chlorine, various impurities are often mixed in. At this time, filtration devices are needed to deal with the possible impurities, such as particulate matter or other pollutants. Existing liquid chlorine solution filtration devices have a complex structure, are difficult to disassemble and assemble, and require purging the system when replacing the filter element, which may cause workers to come into contact with toxic substances. In addition, the filtration efficiency is low, it is easy to clog, and maintenance is frequent. Utility Model Content

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The liquid chlorine solution filtration device is electrically connected to the control panel via a magnetic pump, converting electrical energy into kinetic energy to drive the liquid chlorine flow. It is suitable for continuous flow scenarios. The magnetic pump has an air inlet on top. When the magnetic pump fails or the pressure is insufficient, inert gas can be introduced through the air inlet to pressurize and drive the liquid chlorine flow. It is suitable for intermittent operation or standby drive. By attaching a cooling sleeve to the outer wall of the pressurizing cylinder, the temperature of the liquid chlorine is kept below its boiling point, preventing liquid chlorine from vaporizing and causing filter element blockage or pressure system fluctuations, which greatly improves the filtration efficiency.

[0013] 2. The filtration device for this liquid chlorine solution features two filtration stages: a coarse filter head and a fine filter head. This effectively removes impurities from the liquid chlorine solution. Both filter heads have threads on their outer walls, resulting in a simple structure that is easy to install and remove. When replacing the filter element, simply rotate the filter head to remove it. This achieves highly efficient purification of the liquid chlorine solution. Furthermore, an emergency spray pipe is installed inside the storage tank. When the liquid chlorine solution inside the storage tank leaks, the emergency spray pipe will automatically sense the leak and spray an alkaline liquid to neutralize it, preventing workers from coming into contact with toxic substances.

The top of the connecting flange 401 is provided with an air inlet 405. When the magnetic pump 4 fails or the pressure is insufficient, inert gas can be introduced through the air inlet 405 to pressurize and drive the liquid chlorine flow, which is suitable for intermittent operation or standby drive. By connecting a cooling sleeve 406 to the outer wall of the pressurizing cylinder 402, the temperature of the liquid chlorine is kept below its boiling point to prevent the liquid chlorine from vaporizing and causing filter element blockage or pressure system fluctuations.

[0026] In a preferred embodiment, the coarse filter head 5 includes a coarse filter cylinder 501, a second connector 502 is fixedly installed at the bottom of the coarse filter cylinder 501, a first fixing plate 504 is fixedly assembled in the inner cavity of the coarse filter cylinder 501, a coarse filter element 503 is movably connected to the top of the first fixing plate 504, the outer wall of the coarse filter cylinder 501 is provided with threads, and the inner cavity of the second connector 502 is provided with threads.

[0027] It should be noted that by assembling a coarse filter element 503 in the inner cavity of the coarse filter cartridge 501, larger impurities in the liquid chlorine solution can be removed. Furthermore, by assembling a first fixing plate 504 in the inner cavity of the coarse filter cartridge 501, the coarse filter element 503 is limited, preventing it from falling off and affecting its filtration efficiency. The coarse filter head 5 is conveniently replaced and maintained by having threads in the inner cavity of the second connector 502.

[0029] It should be noted that by assembling a fine filter element 602 in the inner cavity of the fine filter cartridge 601, larger impurities in the liquid chlorine solution can be removed. Furthermore, by assembling a second fixing plate 603 in the inner cavity of the fine filter cartridge 601, the fine filter element 602 is limited, preventing it from falling off and affecting its filtration efficiency.

[0031] It should be noted that by installing an emergency spray pipe 706 inside the storage tank 702, when the liquid chlorine solution inside the storage tank 702 leaks, the emergency spray pipe 706 will automatically sense and spray alkaline liquid to neutralize it, thus preventing personnel from coming into contact with toxic substances. In addition, the emergency spray pipe 706 is electrically connected to the control panel 8, allowing personnel to observe the concentration of the liquid chlorine solution in real time, thus avoiding losses caused by liquid chlorine solution leakage.

[0032] In a preferred embodiment, the support column 3 has two symmetrically arranged columns, and the second mounting plate 2 is fixedly assembled with the drain head 7.

[0033] It should be noted that by providing two support columns 3, the entire device can be fixed, and by fixing the second mounting plate 2 to the funnel head 7, the entire structure is further made more stable.

[0034] Working principle: When using this device, first connect the magnetic pump 4 and the liquid chlorine storage container. The magnetic pump 4 drives the liquid chlorine to flow, and the liquid chlorine will enter the pressurization cylinder 402. Due to the pressure, it will flow through the first connector 403 to the coarse filter head 5. When the liquid chlorine solution enters the coarse filter cylinder 501, the coarse filter element 503 inside will filter out larger impurities. The filtered liquid chlorine solution will continue to flow through the second connector 502 to the fine filter head 6. When the liquid chlorine solution is inside the fine filter cylinder 601, it will undergo a second filtration and purification by the fine filter element 602 inside. The filtered solution will continue to flow through the third connector 701 to the drain head 7. At this time, the filtered liquid chlorine will enter the storage cylinder 702 in the drain head 7. Then, the liquid chlorine solution will enter the conduit 704 from the storage cylinder 702, and then be discharged into the container through the filling head 705, thus completing the entire liquid chlorine solution filtration and purification process.
