Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of horizontal molecular sieve adsorbers, specifically a horizontal molecular sieve adsorber. Background Technology
[0002] Molecular sieve adsorbers, as core equipment for gas separation, dehydration and drying, and impurity purification, are characterized by large loading capacity and uniform material distribution. However, horizontal molecular sieve adsorbers require periodic replacement of the molecular sieves in the adsorption tank. Traditional equipment relies on gravity or manual assistance to remove waste molecular sieves. Due to the horizontal layout of the horizontal structure, a large number of particles are easily left at the bottom of the tank. Especially when the molecular sieves are damp and clumped, the removal time can take several hours, seriously affecting the continuity of production. Furthermore, during the removal process, the dust and impurities remaining on the molecular sieves adhere to the tank wall, requiring manual entry into the tank for cleaning, which increases the labor intensity of workers. Therefore, we propose a horizontal molecular sieve adsorber. Utility Model Content

Two sets of internally threaded sliders 23 are evenly screwed onto the outer side of the bidirectional screw 21. A set of through holes is opened on both the left and right sides of the horizontal adsorption tank 1. The connecting rods 24 pass through the through holes and connect to the internally threaded sliders 23. A second sealing ring is fixedly installed inside the through holes. 27. A set of first sealing rings 26 is fixedly installed on the opposite sides of each of the two sets of second sealing rings 27. A pressure ring 25 is fixedly sleeved on the outer side of the connecting rod 24. The pressure ring 25 fits against the first sealing ring 26. Molecular sieve particles 32 are filled between the two sets of filter discs 3. The first sealing ring 26 and the second sealing ring 27 are integrally molded. The opposite sides of the two sets of first sealing rings 26 fit against the left and right sides of the inner wall of the horizontal adsorption tank 1, respectively. The side of the connecting rod 24 away from the filter disc 3 passes through the first sealing ring 26 and the second sealing ring 27 and connects to the internal threaded slider 23. The sealing ring 27 seals the connection gap between the connecting rod 24 and the through hole of the horizontal adsorption tank 1. The first sealing ring 26 seals the connection gap between the connecting rod 24 and the pressure ring 25 and the horizontal adsorption tank 1. The cooperation of the second sealing ring 27 and the first sealing ring 26 provides a double seal for the connection gaps in the device, preventing material leakage and improving reliability. The top of the horizontal adsorption tank 1 is connected to the feed valve 11 and the material inlet valve 13, and the bottom of the horizontal adsorption tank 1 is connected to the discharge valve 12 and the material discharge valve 14. After opening the feed valve 11… Molecular sieve particles 32 can be poured into the horizontal adsorption tank 1 through the feed valve 11, and the molecular sieve particles 32 will fill the space between the two sets of filter discs 3. Then, the material is fed into the horizontal adsorption tank 1 through the feed valve 13 to come into contact with the molecular sieve particles 32 for adsorption, and the material is discharged through the discharge valve 14. When it is necessary to replace the molecular sieve particles 32, the discharge valve 12 is opened first. At this time, some of the molecular sieve particles 32 in the horizontal adsorption tank 1 will fall and be discharged automatically through the discharge valve 12. The feed valve 13 and the discharge valve 14 are located to the left of the feed valve 11 and the discharge valve 12, respectively.
[0019] A guide rail 2 is fixedly installed on the rear side of the horizontal adsorption tank 1. A bidirectional lead screw 21 is rotatably installed inside the guide rail 2. Two sets of internally threaded sliders 23 are evenly slidably installed inside the guide rail 2. A servo motor 22 is fixedly installed on the left side of the guide rail 2. The left side of the bidirectional lead screw 21 passes through the left side of the guide rail 2 and is connected to the output end of the servo motor 22. The bidirectional lead screw 21 of the servo motor 22 rotates, driving the two sets of internally threaded sliders 23 to move inward synchronously. The two sets of internally threaded sliders 23 drive the two sets of filter discs 3 to move inward synchronously through two sets of connecting rods 24, thereby pushing the molecular sieve particles 32 between the two sets of filter discs 3 inward, thereby increasing the speed at which the molecular sieve particles 32 are discharged from the discharge valve 12. When the filter discs 3 move, they will drive the scraper ring 31 to move synchronously. The scraper ring 31 scrapes off the molecular sieve particles 32 and dust adhering to the inner wall of the horizontal adsorption tank 1 and pushes them toward the discharge valve 12 for discharge, thereby reducing the amount of labor required for workers to clean the inside of the horizontal adsorption tank 1 later.
[0020] Working principle: The second sealing ring 27 seals the connection gap between the connecting rod 24 and the through hole of the horizontal adsorption tank 1, and the first sealing ring 26 seals the connection gap between the connecting rod 24 and the pressure ring 25 and the horizontal adsorption tank 1. The cooperation of the second sealing ring 27 and the first sealing ring 26 provides a double seal for the connection gaps in the device, preventing material leakage and improving reliability. After opening the feed valve 11, the molecular sieve particles 32 can be poured into the horizontal adsorption tank 1, filling the space between the two sets of filter discs 3. Then, the material is fed into the horizontal adsorption tank 1 through the material inlet valve 13 to contact the molecular sieve particles 32 for adsorption, and discharged through the material outlet valve 14. When it is necessary to replace the molecular sieve particles 32... First, open the discharge valve 12. At this time, some molecular sieve particles 32 inside the horizontal adsorption tank 1 will automatically fall and be discharged through the discharge valve 12. Then, the bidirectional lead screw 21 of the servo motor 22 rotates, and the bidirectional lead screw 21 drives two sets of internal thread sliders 23 to move inward synchronously. The two sets of internal thread sliders 23 drive two sets of filter discs 3 to move inward synchronously through two sets of connecting rods 24, thereby pushing the molecular sieve particles 32 between the two sets of filter discs 3 inward, thereby increasing the speed at which the molecular sieve particles 32 are discharged from the discharge valve 12. When the filter discs 3 move, they will drive the scraper ring 31 to move synchronously. The scraper ring 31 scrapes off the molecular sieve particles 32 and dust adhering to the inner wall of the horizontal adsorption tank 1 and pushes them toward the discharge valve 12 for discharge, thereby reducing the amount of labor required for workers to clean the inside of the horizontal adsorption tank 1 later.
