Description

Technical Field

[0001] This utility model relates to the field of candle filters, specifically a purification device for disinfectant production. Background Technology

[0002] When purifying chlorine-containing disinfectants (such as sodium hypochlorite), the sodium hypochlorite needs to be filtered first to remove any insoluble impurities that may be present, such as unreacted solid particles. Then, steps such as evaporation and concentration, and cooling and crystallization are carried out.

[0003] In existing technologies, candle filters are generally used to filter sodium hypochlorite solutions to remove insoluble impurities. The filter mechanism of a candle filter is a tubular porous tube with a filter element inside. It is inserted into the upper connecting plate and threaded to the lower connecting plate. This method requires workers to stand on top of the tank to dismantle the filter one by one during installation and dismantling, which requires a long period of high-altitude work and poses a high safety risk.

Detailed Implementation

[0017] 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.

[0018] Please see Figures 1-4 In this embodiment of the present invention, a purification device for disinfectant production includes a tank 1. A top cover 2 is detachably connected to the top of the tank 1. An outwardly protruding feed pipe 4 is integrally formed on the upper outer periphery of the tank 1. A downwardly protruding discharge pipe 3 is integrally formed at the bottom of the tank 1. The discharge pipe 3 and the feed pipe 4 are connected to the inner cavity of the tank 1. A limiting mechanism is integrally formed on the inner wall of the tank 1 and the bottom of the top cover 2. The limiting mechanism is used to limit the upper connecting plate 7 and the lower connecting plate 9. The upper connecting plate 7 and the lower connecting plate 9 are located in the inner cavity of the tank 1. The upper connecting plate 7 is located above the lower connecting plate 9. A filter mechanism is connected inside the upper connecting plate 7 and the lower connecting plate 9.

[0019] In this embodiment: when purifying and filtering sodium hypochlorite solution, sodium hypochlorite solution is pumped into tank 1 through feed pipe 4. The sodium hypochlorite solution entering tank 1 comes into contact with the filtration mechanism. Solid particles or solid impurities contained in sodium hypochlorite solution are intercepted by the filtration mechanism, and sodium hypochlorite solution is discharged from discharge pipe 3 through the filtration mechanism.

[0020] After prolonged use, the filter mechanism needs to be cleaned or maintained. To do this, rotate and remove the bolts and nuts connecting the tank 1 and the top cover 2. Then, remove the top cover 2. Pull the upper connecting plate 7, which will move the lower connecting plate 9 upwards through the filter mechanism. This allows the upper connecting plate 7, the lower connecting plate 9, and the filter mechanism to be removed simultaneously. After removal, the filter mechanism can be cleaned externally. Once cleaning is complete, the upper connecting plate 7, the lower connecting plate 9, and the filter mechanism can be reinstalled.

[0021] Please refer to this carefully. Figure 2The limiting mechanism includes an upper support ring 6 integrally formed on the upper inner wall of the tank 1, which supports and limits the bottom end of the upper connecting plate 7. The limiting mechanism also includes a lower support ring 10 integrally formed on the lower inner wall of the tank 1, whose top surface supports and limits the bottom end of the lower connecting plate 9. A sealing ring 11 is integrally formed on the inner wall of the tank 1 at the top of the lower support ring 10, which seals the gap between the lower connecting plate 9 and the tank 1. The limiting mechanism also includes a pressing plate 5 integrally formed on the top of the inner wall of the upper cover 2 and protruding downward. The outer circumference of the pressing plate 5 is equal to the inner circumference of the tank 1. The bottom end of the pressing plate 5 is used to press the top end of the upper connecting plate 7. The outer diameter of the upper connecting plate 7 is equal to the inner diameter of the tank 1. The outer diameter of the lower connecting plate 9 is equal to the inner diameter of the upper support ring 6. The inner diameter of the sealing ring 11 is equal to the outer diameter of the lower connecting plate 9.

[0022] In this embodiment: when the upper connecting plate 7, the lower connecting plate 9 and the filter mechanism are reinstalled, the lower connecting plate 9 moves from top to bottom, passing over the upper support ring 6 and moving downward until the lower connecting plate 9 contacts the top of the lower support ring 10. At this time, the upper connecting plate 7 contacts the top of the upper support ring 6. Since the outer circumference of the upper connecting plate 7 is equal to the inner circumference diameter of the tank 1, there will be no installation deviation problem during the installation process. Since the diameter of the upper connecting plate 7 is larger than the diameter of the lower connecting plate 9, the lower connecting plate 9 will not be interfered with by the upper support ring 6 during the downward movement of the filter mechanism.

[0023] Then, the top cover 2 is placed on top of the tank body 1. At this time, the top cover 2 drives the pressing plate 5 to be inserted into the inner wall of the tank body 1. When the top of the top cover 2 contacts the top of the tank body 1, the bottom end of the pressing plate 5 presses against the top end of the upper connecting plate 7, limiting the upper connecting plate 7. At this time, the upper connecting plate 7 restricts the position of the lower connecting plate 9 through the filtering mechanism, thus playing an effective limiting function.

[0024] During the above process, it should be noted that when connecting the upper cover 2, the round hole on the clamping plate 5 should be aligned with the feed pipe 4, and then bolts and nuts can be used to fix and install the upper cover 2.

[0025] Please refer to this carefully. Figure 3The filtration mechanism includes a porous tube 8. The upper connecting plate 7 has a through hole 12 for inserting the porous tube 8. The bottom end of the porous tube 8 is integrally formed with a threaded tube 14. The lower connecting plate 9 has a threaded hole 13 for threaded connection with the threaded tube 14. The upper outer wall of the porous tube 8 has an integrally formed protruding plate 15. The top of the inner wall of the porous tube 8 is threadedly connected with a connector 16. The bottom of the inner wall of the porous tube 8 has an integrally formed porous plate 17 with a porous structure. The bottom end of the threaded tube 14 has an open structure. The inner cavity of the porous tube 8, located between the connector 16 and the porous plate 17, is filled with a filter element.

[0026] In this embodiment: After the upper connecting plate 7, the lower connecting plate 9 and the filter mechanism are disassembled and transferred out of the tank 1, the porous tube 8 is rotated, which drives the threaded tube 14 and the screw hole 13 to rotate and separate. Then, by pulling out the porous tube 8, the porous tube 8 can be separated from the through hole 12, completing the disassembly. Then, a hex wrench is used to connect with the hexagonal hole at the top of the connector 16 and rotated to disassemble the connector 16. Then, the filter element (such as a non-woven filter element) can be taken out from the porous tube 8. After that, the porous tube 8 can be cleaned.

[0027] During installation, the new filter element is placed into the porous tube 8. Then, the porous tube 8 is first inserted into the through hole 12, and the threaded tube 14 is threaded into the screw hole 13. After the threaded tube 14 and the screw hole 13 are fully connected, the protruding plate 15 contacts the top of the upper connecting plate 7. Then, force can be applied to the porous upper connecting plate 7 (e.g., by passing the connecting rope through other holes on the upper connecting plate 7 that are not through holes 12) and the upper connecting plate 7 is pulled by the connecting rope. The upper connecting plate 7 drives the filter mechanism to move synchronously through the protruding plate 15. The filter mechanism can then drive the lower connecting plate 9 to move synchronously, so that the filter mechanism, the upper connecting plate 7, and the lower connecting plate 9 can be installed into the tank 1.

[0028] 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.
