Description

Technical Field

[0001] The utility model relates to the technical field of heating regeneration adsorption type drying machines, in particular to a blast heating regeneration adsorption type drying device. Background Art

[0002] The blast heating regeneration adsorption dryer is a highly efficient compressed air drying equipment. It uses desiccant to adsorb moisture carried in humid gas. In order to continuously provide clean dry compressed gas for plant use, it works based on the principle of temperature and pressure swing adsorption. The ambient air is inhaled through the blower, and the adsorbent is desorbed and regenerated after pressurization and heating. The adsorption process is carried out at room temperature, while the regeneration process is carried out at high temperature.

[0003] In most existing adsorption dryers with forced air heating regeneration, when the adsorption tower is regenerated to restore the adsorption capacity of the adsorbent, hot air is usually introduced into the adsorption tower from the top, and flows through the adsorbent layer from top to bottom to take away the moisture in the adsorbent. However, when the adsorption tower is long, the upper adsorbent is first exposed to the high-temperature hot air, so that the adsorbent closer to the top of the adsorption tower completes the purification and regeneration better, which seriously affects the purification and regeneration efficiency of the adsorbent at the bottom of the adsorption tower.

[0004] Therefore, a blast heating regeneration adsorption drying device is proposed. Utility Model Content

[0005] The utility model aims to provide a blast heating regeneration adsorption drying device to solve the problem that in most existing blast heating regeneration adsorption dryers proposed in the above background technology, when the adsorption tower in the adsorption tower is restored to the adsorption capacity of the adsorbent for regeneration, hot air is usually introduced into the adsorption tower from the top of the adsorption tower, and flows through the adsorbent layer from top to bottom to take away the moisture in the adsorbent. However, when the adsorption tower is long, the upper adsorbent is first exposed to the high-temperature hot air, so that the adsorbent closer to the top of the adsorption tower completes the purification and regeneration better, which seriously affects the purification and regeneration efficiency of the adsorbent in the middle or bottom of the adsorption tower.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a blast heating regeneration adsorption drying equipment, comprising a bracket and an adsorption tower fixedly mounted on the bracket, a movable plate is provided in the adsorption tower, and a transfer box is fixedly connected to the movable plate; a mobilization component for transferring adsorbent is provided on the transfer box, the mobilization component comprises a sealing plate slidably connected in the transfer box, a push block is fixedly connected to the sealing plate, and a block is provided in the adsorption tower for cooperating with the push block to open the sealing plate; and the utility model also comprises a discharge component arranged at the bottom end of the transfer box for the adsorbent to fall out, the discharge component comprises a baffle plate arranged at the bottom end of the transfer box, an inner baffle plate is slidably connected in the baffle plate, and a tension spring is fixedly connected between the transfer box and the baffle plate.

[0012] Preferably, a groove is provided in the inner partition, a plurality of balls are provided in the groove, and a baffle is threadably connected to the inner partition via bolts.

[0013] Preferably, a plurality of through holes are provided on the baffle plate and the inner baffle plate, and the through holes on the baffle plate and the through holes on the inner baffle plate are distributed in a staggered manner.

[0014] Beneficial effects of the utility model:

[0015] The utility model can arrange a transfer assembly so that the moving plate can drive the transfer box to move toward the bottom of the inner cavity of the adsorption tower under the drive of the motor, and the two sealing plates can be separated under the cooperation of the push block and the stop block, so that the adsorbent at the bottom of the adsorption tower can fall into the transfer box. At the same time, under the action of the discharge assembly, when the transfer box drives the adsorbent at the bottom to move upward, the push rod pushes the baffle plate to rotate through the rotating shaft, so that the adsorbent in the transfer box can fall out, and at the same time, the inner partition plate can slide, so that the originally staggered through holes can correspond one by one, thereby accelerating the falling of the adsorbent;

[0016] When the entire device is performing adsorbent purification and regeneration, the adsorbent at the bottom of the adsorption tower can be transferred to the top, thereby reacting with the hot air to remove moisture, thereby improving the purification and regeneration efficiency of the adsorbent at the bottom of the inner cavity of the adsorption tower.

[0027] like Figures 1 to 6 As shown, a specific embodiment of the utility model provides a blast heating regeneration adsorption drying device, including a bracket 1 and an adsorption tower 2 fixedly mounted on the bracket 1, a movable plate 3 is provided in the adsorption tower 2, and a transfer box 4 is fixedly connected to the movable plate 3; a mobilization component for transferring adsorbent is provided on the transfer box 4, and the adsorbent at the bottom of the adsorption tower 2 can be transferred to the top of the inner cavity of the adsorption tower 2 by setting the mobilization component, so as to facilitate the reaction with the heated hot air, thereby taking away the moisture in the adsorbent, the mobilization component includes a sealing plate 5 slidably connected to the transfer box 4, a push block 6 is fixedly connected to the sealing plate 5, and a stopper 7 cooperating with the push block 6 to open the sealing plate 5 is provided in the adsorption tower 2; it also includes a discharge component arranged at the bottom end of the transfer box 4 for the adsorbent to fall out, and the discharge component can be arranged so that the adsorbent transferred from the bottom of the adsorption tower 2 can be discharged from the transfer box 4, the discharge component includes a baffle plate 8 arranged at the bottom end of the transfer box 4, an inner baffle plate 9 is slidably connected to the baffle plate 8, and a tension spring 10 is fixedly connected between the transfer box 4 and the baffle plate 8.

[0028] like Figures 2 to 4As shown, specifically, a support box 11 is fixedly installed in the adsorption tower 2, a motor 12 is fixedly installed in the support box 11, a threaded rod 13 is fixedly connected to the output shaft of the motor 12, and the threaded rod 13 is threadedly connected to the movable plate 3, a limiting groove 14 is provided in the adsorption tower 2, and the movable plate 3 is slidably connected in the limiting groove 14, when the adsorption tower 2 desorbs and regenerates the adsorbent, the motor 12 is started to drive the threaded rod 13 to rotate, so that the movable plate 3 moves downward in the limiting groove 14, and the movable plate 3 moves downward to drive the transfer box 4 to move downward, and the transfer box 4 moves downward to gradually enter the adsorbent and approach the bottom of the adsorption tower 2, and the sealing plate 5 is fixedly connected with a block 15, and a spring 16 is fixedly connected between the block 15 and the transfer box 4. When the transfer box 4 moves to the bottom of the adsorption tower 2, the push block 6 gradually approaches the stop block 7 and applies pressure to the stop block 7. Since the push block 6 and the stop block 7 are both provided with inclined surfaces of the same angle, the two adjacent sealing plates 5 are separated. At this time, the spring 16 is forced to contract and generate a reaction force, and the separation of the sealing plates 5 allows the adsorbent at the bottom position of the adsorption tower 2 to slide into the transfer box 4. Here, the tension spring 10 is selected with higher strength, so that the gravity generated by the adsorbent in the transfer box 4 will not separate the blocking plate 8 from the transfer box 4.

[0029] like Figures 2 to 6As shown, specifically, the baffle plate 8 is rotatably connected to the transfer box 4 through a rotating shaft, the baffle plate 8 is inclined and close to the bottom end of the transfer box 4, a connecting plate 17 is fixedly connected in the adsorption tower 2, and a push rod 18 is fixedly connected to the bottom end of the connecting plate 17. When the transfer box 4 is filled with adsorbent, the reverse driving motor 12 causes the moving plate 3 to drive the transfer box 4 to move upward and reset, until the transfer box 4 moves to the top of the inner cavity of the adsorption tower 2, the baffle plate 8 at the bottom end of the transfer box 4 contacts the push rod 18, so that the push rod 18 pushes the baffle plate 8 with the cooperation of the connecting plate 17 so that the baffle plate 8 is moved through the rotating shaft. The baffle plate 8 is rotated, and at this time, the baffle plate 8 is no longer tightly attached to the transfer box 4. One end of the baffle plate 8 pulls the tension spring 10 downward under the action of the push rod 18. The tension spring 10 is forced to shrink and generate a reaction force, so that the adsorbent in the transfer box 4 falls down. A groove 19 is provided in the inner baffle plate 9, and a plurality of balls 20 are provided in the groove 19. A baffle plate 21 is connected to the inner baffle plate 9 through bolt threads. A plurality of through holes 22 are provided on the baffle plate 8 and the inner baffle plate 9, and the through holes 22 on the baffle plate 8 are distributed in a staggered manner. At the same time, the baffle plate 8 One end moves downward so that the inner partition plate 9 slides toward the other end in the blocking plate 8. The setting of the ball 20 can reduce friction and facilitate the sliding of the inner partition plate 9. When the inner partition plate 9 slides to the other end, the through holes 22 on the blocking plate 8 and the inner partition plate 9 are staggered and correspond to each other, so that the adsorbent in the transfer box 4 can fall from the through holes 22, thereby accelerating the falling speed of the adsorbent in the transfer box 4. After all the adsorbent in the transfer box 4 falls, the sealing plate 5 is reset under the reaction force of the spring 16, so that the top of the transfer box 4 is re-sealed. The transfer of the adsorbent at the bottom of the adsorption tower 2 to the top of the inner cavity of the adsorption tower 2 is completed, so that the incoming hot air can react with it. When the next adsorbent transfer is circulated, after the transfer box 4 moves downward and the baffle plate 8 is separated from the push rod 18, the baffle plate 8 is reset under the reaction force of the tension spring 10 and is tightly attached to the bottom end of the transfer box 4, thereby achieving the sealing of the bottom end of the transfer box 4. After the baffle plate 8 is reset, the inner partition plate 9 inside it slides to the initial position again, and the through holes 22 on the baffle plate 8 and the through holes 22 on the inner partition plate 9 are again staggered.
