[0032] Please refer to Figures 1-7A refrigerant storage tank for chemical production includes a tank body 1. A sealing cover 2 is installed on the side of the tank body 1. The sealing cover 2 is provided with multiple limiting blocks 28. The tank body 1 is provided with multiple limiting grooves 29 to facilitate the limiting of the sealing cover 2. A first sealing gasket 3 is provided between the sealing cover 2 and the tank body 1. A square groove 4 is provided at one end of the sealing cover 2 inside the tank body 1. A first rotating shaft 5 is rotatably connected to the sealing cover 2. A first bevel gear 6 is fixedly connected to one end of the first rotating shaft 5 extending into the square groove 4. Multiple sliding grooves 7 are evenly provided on the sealing cover 2. A locking post 8 is slidably provided inside each of the multiple sliding grooves 7. A first inclined side 9 is provided on each locking post 8. A screw rod 10 is threadedly connected to the side end of each locking post 8. A second rotating shaft 11 is fixedly connected to the side end of the screw rod 10. The second rotating shaft 11 is connected to the sealing cover. 2. Rotary connection: Multiple second rotating shafts 11 extend into the square groove 4, and one end is fixedly connected to a second bevel gear 12. Multiple second bevel gears 12 mesh with a first bevel gear 6. Multiple slots 13 are evenly arranged inside the tank body 1. A second inclined edge 14 is provided on the side end of the slot 13. A second annular groove 24 is provided on the outside of the sealing cover 2. A second sealing ring 25 is sleeved inside the second annular groove 24. The locking post 8 is located in the middle of the first sealing gasket 3 and the second sealing ring 25 to ensure the sealing performance between the sealing cover 2 and the tank body 1. A sealing plate 26 is installed on the sealing cover 2 to seal the square groove 4, which facilitates the sealing of the square groove 4. A second sealing gasket 27 is provided between the sealing plate 26 and the sealing cover 2 to ensure the sealing performance between the sealing plate 26 and the sealing cover 2.
[0033] Specifically, the sealing cap 2 is inserted into the tank body 1, and multiple limiting blocks 28 are respectively inserted into multiple limiting grooves 29. Then, the first rotating shaft 5 and the first bevel gear 6 are rotated clockwise. The first bevel gear 6 drives multiple second bevel gears 12, multiple second rotating shafts 11, and multiple screws 10 to rotate. The rotation of the multiple screws 10 causes multiple locking pins 8 to move outward of the sliding groove 7, and the locking pins 8 are respectively inserted into the multiple locking grooves 13. Through the cooperation of the first inclined side 9 and the second inclined side 14, the sealing cap 2 is pressed tightly onto the tank body 1, thereby completing the sealing installation of the sealing cap 2 onto the tank body 1. By rotating the first rotating shaft 5 and the first bevel gear 6 counterclockwise, the first bevel gear 6 drives multiple second bevel gears 12... Multiple second rotating shafts 11 and multiple screws 10 rotate, causing multiple locking pins 8 to move into the sliding groove 7, separating the multiple locking pins 8 from the multiple locking grooves 13 respectively. Then, the sealing cover 2 can be removed from the tank body 1. This avoids the need to remove multiple bolts to disassemble the sealing cover 2. The method of disassembling the sealing cover 2 is simple and time-saving, improving the efficiency of internal maintenance of the tank body 1. The sealing plate 26 and the second sealing gasket 27 seal the square groove 4. The second sealing ring ensures the sealing performance of the connection between the first rotating shaft 5 and the sealing cover 2. The first sealing ring 19 and the sealing gasket facilitate the double-layer sealing between the sealing cover 2 and the tank body 1, thereby ensuring the sealing effect of the connection between the sealing cover 2 and the tank body 1.
[0034] Please see Figure 1 , Figure 4 , Figure 5 and Figure 7 A circular groove 15 is provided on the sealing cover 2 at a position corresponding to the first rotating shaft 5. A rotating seat 16 is rotatably connected inside the circular groove 15. The side end of the rotating seat 16 is fixedly connected to the side end of the first rotating shaft 5. A regular hexagonal groove 17 is provided on the side end of the rotating seat 16 to facilitate the rotation of the first rotating shaft 5. A first annular groove 18 is provided on the outside of the first rotating shaft 5. A first sealing ring 19 is sleeved inside the first annular groove 18 to ensure the sealing between the first rotating shaft 5 and the sealing cover 2. A limiting ring 20 is installed on the sealing cover 2. The side end of the limiting ring 20 contacts the side end of the rotating seat 16 to facilitate limiting the rotating seat 16 inside the circular groove 15. Multiple fixing grooves 21 are arranged in a circular array on the side end of the rotating seat 16. A fixing screw 22 is threadedly connected to the limiting ring 20. A fixing post 23 that matches the fixing groove 21 is fixedly connected to the side end of the fixing screw 22 to facilitate the fixing of the rotating seat 16.
[0035] Specifically, by inserting a hexagonal wrench into the hexagonal groove 17, it is easy to rotate the rotating base 16, the first rotating shaft 5, and the first bevel gear 6. The limiting ring 20 helps to limit the rotating base 16 inside the circular groove 15. By rotating the fixing screw 22 clockwise, the fixing screw 22 is moved to the side closer to the rotating base 16, and the fixing post 23 is inserted into the corresponding fixing groove 21. During use, the rotating base 16 is prevented from rotating, ensuring the stability of the connection between the sealing cover 2 and the tank body 1.
[0036] In summary, when using the overall equipment:
[0037] Insert the sealing cap 2 into the tank body 1, and insert multiple limiting blocks 28 into multiple limiting grooves 29 respectively. At this time, the second sealing ring 25 is located on the inner side of the tank body 1 relative to the multiple limiting grooves 29. Then, insert a hex wrench into the regular hexagonal groove 17 and rotate the rotating seat 16, the first rotating shaft 5 and the first bevel gear 6 clockwise with the hex wrench. The first bevel gear 6 drives multiple second bevel gears 12, multiple second rotating shafts 11 and multiple screws 10 to rotate. The rotation of multiple screws 10 causes multiple locking pins 8 to move outward of the sliding groove 7 and insert the locking pins 8 into the multiple locking grooves 13 respectively. Through the cooperation of the first inclined side 9 and the second inclined side 14, the sealing cap 2 is pressed onto the tank body 1, thereby completing the sealing installation of the sealing cap 2 onto the tank body 1. Then, tighten the fixing screw 22 to insert the fixing pin 23 into the corresponding fixing groove 21 to fix the rotating seat 16.
[0038] When it is necessary to remove the sealing cap 2, loosen the fixing screw 22 to separate the fixing post 23 from the fixing groove 21. Then, use a hex wrench to rotate the rotating base 16, the first rotating shaft 5 and the first bevel gear 6 counterclockwise. The first bevel gear 6 drives multiple second bevel gears 12, multiple second rotating shafts 11 and multiple screws 10 to rotate. The rotation of multiple screws 10 causes multiple locking posts 8 to move into the sliding groove 7, so that multiple locking posts 8 are separated from multiple locking grooves 13 respectively. Then, the sealing cap 2 can be pulled out from the inside of the tank body 1.
[0039] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
