Description

Technical Field

[0001] This utility model relates to the field of molecular sieve processing, and in particular to a reaction tower for preparing molecular sieve products. Background Technology

[0002] Molecular sieves are artificially synthesized hydrated aluminosilicates or natural zeolites that have the function of screening molecules. When a fluid flows through a molecular sieve, some molecules in the fluid collide with the surface of the adsorbent due to irregular motion, resulting in molecular aggregation on the surface. This reduces the number of such molecules in the fluid, achieving the purpose of separation and removal. In the preparation of molecular sieves, the molecular sieve production material is introduced into a reaction tower, where it comes into contact with and reacts with a fixed catalyst or adsorbent, producing the desired chemical transformation or separation effect.

[0003] For example, patent document CN221536693U discloses a reaction tower for preparing molecular sieve products. During use, the molecular sieve and the desiccant reacting together are transported into the interior of the reaction tower body, the sealing plate is closed, and heating is performed using a heating rod. The motor drives the rotating seat to rotate gear two, which in turn drives gear three to rotate gear four. The connecting plate drives stirring rod one to rotate. At the same time as the rotating seat rotates, stirring rod two also rotates. Stirring rod two rotates in the forward direction, while stirring rod one rotates in a small circle in the reverse direction. This ensures that the molecular sieve is continuously stirred during the reaction, mixes evenly with the desiccant, reduces reaction time, and improves production efficiency.

[0004] However, after the molecular sieve reaction tower is used, some material will remain on the inner wall. In order not to affect the next use and the molecular sieve reaction, the reaction tower usually needs to be cleaned. Currently, most of the cleaning is done manually by hand-held water spray guns to rinse the inner wall of the reaction tower. This method is labor-intensive, and it is not convenient for operators to observe the inner wall of the reaction tower, making the cleaning operation very inconvenient. Utility Model Content

[0005] The purpose of this invention is to provide a reaction tower for preparing molecular sieve products in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A reaction tower for preparing molecular sieve products includes a tower body, a stirring and scraping mechanism disposed within the tower body, the stirring and scraping mechanism including a hollow shaft rotatably mounted within the tower body, multiple hollow rods fixedly connected to the side wall of the hollow shaft, a water spray box fixedly connected to the end of each hollow rod away from the hollow shaft, water spray pipes fixedly connected to both sides of the water spray box, a scraper strip disposed at the end of the water spray box away from the hollow rods, an elastic mechanism disposed within the water spray box for driving the scraper strip to move, a sealing mechanism disposed within the water spray pipes, a water inlet mechanism communicating with the hollow shaft disposed at the top of the tower body, and a power mechanism disposed at the top of the tower body for driving the hollow shaft to rotate.

[0008] Preferably, the elastic mechanism includes a movable plate that is slidably connected inside the spray box. A movable rod is fixedly connected to the side of the movable plate away from the hollow rod. The movable rod extends out of the spray box and is fixedly connected to the scraper. The movable rod is slidably connected to the spray box. A first spring is sleeved on the movable rod and is fixedly connected between the movable plate and the inner wall of the spray box.

[0009] Preferably, the sealing mechanism includes a fixed base, which is fixedly connected to the inner wall of the water spray pipe. A second spring is fixedly connected to the side of the fixed base near the water outlet of the water spray pipe, and a sealing ball is fixedly connected to the other end of the second spring. Under the action of the second spring, the sealing ball is stuck at the water outlet of the water spray pipe.

[0010] Preferably, the water inlet mechanism includes a fixed column, which is fixedly connected to the top of the tower body. A fixed ring is fixedly connected to the top of the fixed column. A hollow circular shell is rotatably engaged on the fixed ring. A water inlet pipe is fixedly connected to the fixed ring and communicates with the hollow circular shell. The hollow circular shell is fixedly connected to a hollow shaft. A through hole is provided on the hollow shaft, and the hollow circular shell and the hollow shaft communicate with each other through the through hole.

[0011] Preferably, the power mechanism includes a bracket, which is fixedly connected to the top of the tower body. A motor is fixedly connected to the top of the bracket, and the output shaft of the motor is fixedly connected to a coupling. The top of the hollow shaft is fixedly connected to the coupling.

[0012] Preferably, a helical blade is fixedly connected to the hollow shaft.

[0013] The beneficial effects are as follows: external water is introduced into the hollow shaft through the water inlet mechanism, and then the water flows into the spray box through the hollow rod. Under the action of water pressure, the elastic mechanism drives the scraper to move, and the scraper fits against the inner wall of the tower. Due to the movement of the elastic mechanism, the water can be sprayed onto the inner wall of the tower through the spray pipe. The scraper rotates along the inner wall of the tower to scrape away debris, eliminating the need for manual cleaning and making it convenient to use. In addition, a sealing mechanism is installed inside the spray pipe. Under natural conditions or when the material is stirred, the sealing mechanism blocks the opening of the spray pipe to prevent material from entering the spray pipe. During cleaning, under the action of water pressure, the sealing mechanism no longer blocks the opening of the spray pipe, and the water flows out smoothly. Furthermore, the sealing mechanism can disperse the water flow and expand the rinsing range.

Therefore, they should not be construed as limitations on this utility model.

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figures 1-7 As shown, a reaction tower for preparing molecular sieve products includes a tower body 1. A feed pipe 101 and an exhaust pipe 102 are fixedly connected to the top of the tower body 1, and a discharge pipe 103 is fixedly connected to the bottom of the tower body 1. Multiple heating rings 104 are fixed to the side walls of the tower body 1. The heating rings 104 are heated using heating wires or heating tubes. The heating rings 104 are existing technology and will not be described in detail. A stirring and scraping mechanism 2 is provided inside the tower body 1. The stirring and scraping mechanism 2 includes... Includes a hollow shaft 201, which is mounted inside the tower body 1 via bearings. Multiple hollow rods 202 are welded to the side wall of the hollow shaft 201. A water spray box 203 is welded to the end of each hollow rod 202 away from the hollow shaft 201. Water spray pipes 205 are welded to both sides of the water spray box 203. A scraper 204 is provided at the end of the water spray box 203 away from the hollow rods 202. During the reaction stage, the hollow shaft 201 drives the hollow rods 202 to rotate, and the hollow rods 202... The material is stirred, and a spiral blade 7 is fixedly connected to the hollow shaft 201. The rotation of the spiral blade 7 can turn the material upward, improve the stirring effect, speed up the reaction, and improve efficiency. An elastic mechanism 3 is set in the water spray box 203. The elastic mechanism 3 is used to drive the scraper 204 to move. During cleaning, water flows from the hollow shaft 201 through the hollow rod 202 into the water spray box 203. Under the action of water pressure, the elastic mechanism 3 drives the scraper 204 to move, so that the scraper 204 is in contact with the inner wall of the tower body 1, and the water flows out through the water spray pipe 205. With the circumferential movement of the scraper 204, the inside of the tower body 1 is rinsed and scraped. A sealing mechanism 4 is set in the water spray pipe 205 to prevent material from entering the water spray pipe 205. A water inlet mechanism 5 connected to the hollow shaft 201 is set at the top of the tower body 1. A power mechanism 6 for driving the hollow shaft 201 to rotate is set at the top of the tower body 1.

[0028] The elastic mechanism 3 includes a movable plate 301, which is slidably connected inside the water spray box 203. A movable rod 302 is fixedly connected to the side of the movable plate 301 away from the hollow rod 202. The movable rod 302 extends out of the water spray box 203 and is fixedly connected to the scraper 204. The movable rod 302 is slidably connected to the water spray box 203. The water flow will push the movable plate 301 to move, thereby causing the movable rod 302 to drive the scraper 204 to move. A first spring 303 is sleeved on the movable rod 302. The first spring 303 is fixedly connected between the movable plate 301 and the inner wall of the water spray box 203. The first spring 303 is always in a compressed state. Therefore, in the natural state, the scraper 204 is in contact with the water spray box 203. Thus, during the stirring of materials, the scraper 204 does not contact the inner wall of the tower body 1, which can reduce wear on the one hand and reduce the power consumed by stirring on the other hand.

[0029] The blocking mechanism 4 includes a fixed base 401, which is welded to the inner wall of the water spray pipe 205. A second spring 402 is fixedly connected to the side of the fixed base 401 near the outlet of the water spray pipe 205. A blocking ball 403 is fixedly connected to the other end of the second spring 402. The second spring 402 is always in a stretched state. Therefore, under the action of the second spring 402, the blocking ball 403 is stuck at the outlet of the water spray pipe 205. Under the action of water pressure, the water flow will push the blocking ball 403 away from the water spray pipe 205, so that the water flow can be sprayed out smoothly. Moreover, the blocking ball 403 can disperse the water flow and expand the spray range.

[0030] The water inlet mechanism 5 includes a fixed column 501, which is fixedly connected to the top of the tower body 1. A fixed ring 502 is fixedly connected to the top of the fixed column 501. A hollow circular shell 503 is rotatably engaged on the fixed ring 502. A water inlet pipe 504 is fixedly connected to the fixed ring 502 and communicates with the hollow circular shell 503. A high-pressure water source is connected to the outside of the water inlet pipe 504, and water flows through the water inlet pipe 504 into the interior of the hollow circular shell 503. 503 is welded onto the hollow shaft 201. The hollow shaft 201 has a through hole 2011. The hollow shell 503 and the hollow shaft 201 are connected through the through hole 2011. Water flows into the hollow shaft 201 through the through hole 2011. Since the hollow shell 503 can rotate on the fixed ring 502, water can continuously flow into the hollow shaft 201 as the hollow shaft 201 drives the hollow shell 503 to rotate.

[0031] The power mechanism 6 includes a bracket 601, which is connected to the top of the tower body 1 by screws. A motor 602 is bolted to the top of the bracket 601. The output shaft of the motor 602 is fixedly connected to a coupling 603. The top of the hollow shaft 201 is fixedly connected to the coupling 603.

[0032] Working principle: During use, the materials required for the reaction are added into the tower body 1 through the feed pipe 101. The heating ring 104 is energized to start heating, and the hollow shaft 201 is driven to rotate by the motor 602. The hollow shaft 201 drives the hollow rod 202 and the spiral blade 7 to rotate. The hollow rod 202 stirs the materials, and the spiral blade 7 tumbles the materials upward to improve the stirring effect. The gas containing water vapor during the reaction is discharged through the exhaust pipe 102. After the reaction is completed, the materials are discharged through the discharge pipe 103. When it is necessary to clean the inner wall of the tower body 1, the external high-pressure water source is introduced into the hollow shaft through the water inlet pipe 504. Inside the round shell 503, water flows sequentially through the through hole 2011, the hollow shaft 201, and the hollow rod 202. Under the action of water pressure, the water flow pushes the movable plate 301 to move. The movable plate 301 drives the scraper 204 to move through the movable rod 302. The scraper 204 is in contact with the inner wall of the tower body 1. At the same time, water flows from the spray box 203 into the spray pipe 205. Under the action of water pressure, the water flow pushes open the sealing ball 403, so that the water flow is sprayed out from the spray pipe 205, thereby rinsing the inner wall of the tower body 1. At this time, the hollow shaft 201 is rotated, so that the scraper 204 scrapes the inner wall of the tower body 1.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
