Description

Technical Field

[0001] This invention relates to the field of molecular sieve dehydration technology, and in particular to a continuous dehydration device for adsorbents. Background Technology

[0002] Molecular sieves are synthetically produced hydrated aluminosilicates (zeolites) or natural zeolites that sieve molecules. Structurally, they contain numerous uniformly sized channels and neatly arranged pores. Molecular sieves with different pore sizes separate molecules of different sizes and shapes. Different pore sizes are obtained based on the molecular ratio of SiO2 to Al2O3. Types include: 3A (potassium A type), 4A (sodium A type), 5A (calcium A type), 10Z (calcium Z type), 13Z (sodium Z type), Y (sodium Y type), and sodium mordenite zeolite, etc. They possess high adsorption capacity, strong selectivity, and high temperature resistance. Existing dehydration devices primarily use air blowing to dehydrate adsorbents. This method significantly reduces the overall dehydration effect when large quantities of adsorbent are stacked together. For continuous and large quantities of adsorbent, the overall dehydration rate decreases, resulting in unsatisfactory dehydration. Summary of the Invention

[0004] The present invention achieves the above objectives through the following technical solutions:

[0005] A continuous dehydration device for an adsorbent includes a drive mechanism, a dehydration mechanism for air-drying the adsorbent, a conveying mechanism for conveying the pre-dehydrated adsorbent, and an adsorption mechanism for adsorbing the adsorbent conveyed within the conveying mechanism. The drive mechanism is located below the dehydration mechanism, the conveying mechanism is located inside the dehydration mechanism, and the adsorption mechanism is located at the end of the conveying mechanism.

[0006] Preferably, the dehydration mechanism includes a dehydration box, a dehydration cylinder, a feed hopper, a discharge pipe, and a dehydration sleeve. The dehydration cylinder is installed inside the dehydration box, and the dehydration sleeve is located inside the dehydration cylinder. A spiral plate is welded to the outside of the dehydration sleeve. An air inlet is provided at one end of the dehydration cylinder. The feed hopper is welded to the upper side of the dehydration cylinder, and the upper end of the feed hopper extends out of the top of the dehydration box. The discharge pipe is welded to the lower side of the dehydration cylinder and extends out of the lower end of the dehydration box.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] like Figures 1-8 As shown, a continuous dehydration device for an adsorbent includes a drive mechanism 4, a dehydration mechanism 1 for air-drying the adsorbent, a conveying mechanism 2 for conveying the pre-dehydrated adsorbent, and an adsorption mechanism 3 for adsorbing the adsorbent conveyed in the conveying mechanism 2. The drive mechanism 4 is located below the dehydration mechanism 1, the conveying mechanism 2 is located inside the dehydration mechanism 1, and the adsorption mechanism 3 is located at the end of the conveying mechanism 2.

[0029] In this embodiment, the dehydration mechanism 1 includes a dehydration box 11, a dehydration cylinder 12, a feed hopper 13, a discharge pipe 14, and a dehydration sleeve 15. The dehydration cylinder 12 is installed inside the dehydration box 11, and the dehydration sleeve 15 is located inside the dehydration cylinder 12. A spiral plate is welded to the outside of the dehydration sleeve 15. An air inlet is provided at one end of the dehydration cylinder 12. The feed hopper 13 is welded to the upper side of the dehydration cylinder 12, and the upper end of the feed hopper 13 extends out of the top of the dehydration box 11. The discharge pipe 14 is welded to the lower side of the dehydration cylinder 12 and extends out of the lower end of the dehydration box 11. The adsorbent to be dehydrated is introduced into the space between the dehydration cylinder 12 and the dehydration sleeve 15 by the feed hopper 13. The adsorbent is transported to the drive mechanism 4 by the rotation of the dehydration sleeve 15. At the same time, the air inlet at one end of the dehydration cylinder 12 is used to send flowing air into the conveying mechanism 2.

[0030] In this embodiment: the conveying mechanism 2 includes a spiral conveying plate 21, a conveying cylinder 22, a fan 23, and a rotating gear 24. The conveying cylinder 22 is rotatably connected inside the dehydration cylinder 12. The spiral conveying plate 21 is welded to the outside of the conveying cylinder 22. The fan 23 is bolted to one end of the dehydration box 11. The rotating gear 24 is located below the conveying cylinder 22. A T-groove that mates with the dehydration cylinder 12 is opened on the outer side of one end of the dehydration sleeve 15. The other end of the dehydration sleeve 15 is rotatably connected to the inner end face of the dehydration cylinder 12. An air guide groove is opened on the outer side of the conveying cylinder 22. A fixed part is located on the outer side of the conveying cylinder 22 at the rotating gear 24. The dehydration cylinder 12 has teeth that mesh with the rotating gear 24. The dehydration sleeve 15 has an outlet slot near the rotating gear 24. The rotation of the rotating gear 24 drives the dehydration sleeve 15 and the conveying cylinder 22 to rotate in opposite directions. The pre-dehydrated adsorbent is introduced into the space between the dehydration sleeve 15 and the conveying cylinder 22 through the outlet slot of the dehydration sleeve 15. At the same time, the dehydrating agent is conveyed to one side by the spiral conveying plate 21 under the rotation of the conveying cylinder 22. During this process, the fan 23 is used to blow air into the dehydration box 11 and between the dehydration sleeve 15 and the conveying cylinder 22.

[0031] In this embodiment, the adsorption mechanism 3 includes a conical hood 31 and a conical seat 32. The conical hood 31 is welded to the end of the conveying cylinder 22, and the conical seat 32 is disposed inside the conical seat 32. There is a 1cm gap between the conical hood 31 and the conical seat 32. The gap between the conical hood 31 and the conical seat 32 is used to communicate with the inside of the conveying cylinder 22. By the high-speed airflow from the outside of the conical hood 31 and the conical seat 32, a suction force is formed at the gap between the conical hood 31 and the conical seat 32. Then, the adsorbent on the outside of the conveying cylinder 22 is absorbed by the air guide groove on the outside of the conveying cylinder 22, thereby completing the secondary dehydration process.

[0032] In this embodiment, the drive mechanism 4 includes a drive motor 41, a worm 42, and a worm wheel 43. The drive motor 41 is bolted to the front of the dehydration tank 11. The worm wheel 43 is connected to the rotating gear 24 via a transmission shaft. The worm 42 is located below the worm wheel 43, and the worm wheel 43 is connected to the rotating part of the drive motor 41. The rotating part of the drive motor 41 drives the worm 42 to rotate, and the rotation of the worm 42 drives the worm wheel 43 to rotate. The rotating gear 24, connected by the transmission shaft between the worm wheel 43 and the rotating gear 24, also rotates accordingly.

[0033] Working principle: In use, first turn on the power of the blower 23 to make it rotate at high speed and generate air force. The air force generated by the blower 23 blows into the dehydration tank 11 and is sent into the position between the dehydration sleeve 15 and the conveying cylinder 22 through the air inlet at one end of the dehydration cylinder 12. There is high-speed airflow between the dehydration tank 11 and the dehydration cylinder 12, and a preliminary air drying and dehydration area is formed on the outside of the dehydration sleeve 15. Then the air is sent out from the other end of the dehydration tank 11. At the same time, during the process of air flowing out of the dehydration tank 11... In the middle, the gap between the conical hood 31 and the conical seat 32 generates suction under the drive of high-speed flowing air. Then, the air inside the conveying cylinder 22 flows towards the conical hood 31 along its interior. Subsequently, the air flowing inside the conveying cylinder 22 flows out from the conical hood 31 and the conical seat 32. This position is the secondary air drying and dehydration area. Then, the adsorbent to be dehydrated is introduced into the feed hopper 13. The adsorbent is introduced into the dehydration cylinder 12 and the dehydration sleeve 15 through the feed hopper 13. At the same time, the drive motor 41 rotates. The worm gear 42 rotates, which in turn drives the worm wheel 43 to rotate synchronously. The transmission shaft between the worm wheel 43 and the rotating gear 24 drives the rotating gear 24 to rotate. Subsequently, the dehydration sleeve 15 and the conveying cylinder 22 rotate in opposite directions via the transmission of the rotating gear 24. Then, the adsorbent between the dehydration sleeve 15 and the dehydration cylinder 12 moves towards the adsorption mechanism 3 under the action of the spiral plate on the outer side of the dehydration sleeve 15. Simultaneously, during this process, the adsorbent undergoes initial dehydration. When the adsorbent falls from the outlet of the dehydration sleeve 15 into the space between the conveying cylinder 22 and the dehydration sleeve 15, the adsorbent is transported towards the discharge pipe 14 by the reverse rotation of the conveying cylinder 22 and the spiral conveying plate 21. During this process, air is sent into the space between the conveying cylinder 22 and the dehydration sleeve 15 through the air inlet of the dehydration cylinder 12. The adsorbent is dehydrated again by the flowing air. At the same time, the adsorbent at this position is subjected to a second water absorption and dehydration process by the air guide groove of the conveying cylinder 22.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
