Adsorption drier with adsorbent protection screen

Abstract

This utility model relates to an adsorption dryer with an adsorbent protective filter, belonging to the technical field of adsorption dryers. It includes a dryer body with two towers. A support filter is fixedly connected to the inner side of each tower. An adsorbent body is mounted on top of the support filter. A sealing cover is provided on the top of each tower. Connecting components for easy connection to the tower are provided on both sides of the sealing cover. Each connecting component includes a frame fixedly connected to the left and right sides of the sealing cover. This adsorption dryer with an adsorbent protective filter uses a design that achieves non-contact power transmission through magnetic coupling between a driving magnetic chuck and a driven magnetic chuck. When cleaning the support filter is required, the operator only needs to rotate a lever outside the tower, causing the driving magnetic chuck to rotate. The resulting rotating magnetic field penetrates the tower wall, thereby driving a scraper to clean the support filter.

Description

Technical Field

[0001] This utility model relates to the field of adsorption dryer technology, specifically an adsorption dryer with an adsorbent protective filter. Background Technology

[0002] In industrial production, compressed air is widely used in many fields as an important power source and process medium. However, compressed air often contains a large amount of moisture. If it is not dried, the moisture will cause serious corrosion to the equipment and pipelines of the compressed air system, affecting the service life and performance of the equipment, and may also lead to a decline in product quality or even safety accidents.

[0003] Over time, impurities and dust accumulate on the filters inside dryers, especially the support filters, affecting their air permeability and filtration efficiency. However, cleaning existing dryers typically requires opening the entire dryer and disassembling the filters for cleaning. This is not only cumbersome but also risks damaging the dryer's seals, increasing the risk of equipment failure. Furthermore, it's inconvenient to disassemble and reassemble the tower's sealing cover when replacing the adsorbent. Therefore, this paper proposes an adsorption dryer with an adsorbent protection filter to address these issues. Utility Model Content

A connecting plate is fixedly connected to the bottom of the connecting block, and a locking rod is fixedly connected to the mounting surface of the connecting plate. Connecting cylinders that are compatible with the locking rods are fixedly connected to both the left and right sides of the tower body.

[0008] The inner side of the tower body is equipped with a scraping assembly for cleaning the support filter screen.

[0015] Compared with the prior art, this utility model provides an adsorption dryer with an adsorbent protective filter, which has the following beneficial effects:

[0016] This adsorption dryer with an adsorbent protective filter uses a design that achieves non-contact power transmission through magnetic coupling between a drive magnetic chuck and a driven magnetic chuck. When the support filter needs to be cleaned, the operator only needs to rotate the rotating rod outside the tower body to drive the drive magnetic chuck to rotate. The resulting rotating magnetic field penetrates the tower wall and drives the driven magnetic chuck inside to rotate synchronously, thereby driving the scraper to scrape and clean the support filter. In addition, the operator can easily connect and disconnect the sealing cover from the tower body by rotating the operating wheel clockwise or counterclockwise, which greatly saves time and labor costs for replacing or maintaining the adsorbent.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 3 An adsorption dryer with an adsorbent protective filter screen in this embodiment includes a dryer body 1. The dryer body 1 is provided with two towers 101. A support filter screen 102 is fixedly connected to the inner side of the tower 101. An adsorbent body 103 is provided on the top of the support filter screen 102. A sealing cover 104 is provided on the top of the tower 101. The left and right sides of the sealing cover 104 are provided with connecting components that facilitate connection with the tower 101.

[0023] Please see Figure 1 In this embodiment, the connecting assembly includes a frame 2 that is fixedly connected to the left and right sides of the sealing cover 104 respectively. A threaded rod 3 is rotatably connected to the inner side of the frame 2. An operating wheel 4 is fixedly connected to the other end of the threaded rod 3. A threaded block 5 is threadedly connected to the outer side of the threaded rod 3. A connecting block 6 is fixedly connected to the bottom of the threaded block 5. A connecting plate 7 is fixedly connected to the bottom of the connecting block 6. A locking rod 8 is fixedly connected to the mounting surface of the connecting plate 7. Connecting cylinders 9 that are compatible with the locking rod 8 are fixedly connected to both the left and right sides of the tower body 101.

[0024] The inner side of the tower body 101 is provided with a scraping assembly for cleaning the support filter screen 102. The scraping assembly includes a rotating ring 10 fixedly connected to the inner side of the tower body 101. A driven magnetic chuck 11 is rotatably connected to the inner side of the rotating ring 10. An installation rod 12 is fixedly connected to the fixed surface of the driven magnetic chuck 11. A scraper 13 is fixedly connected to the outer side of the installation rod 12.

[0025] Specifically, a drive magnetic chuck 14 is provided on the opposite side of each of the two tower bodies 101. A rotating rod 15 is fixedly connected to the fixed surface of the drive magnetic chuck 14. The magnetic poles of the drive magnetic chuck 14 and the driven magnetic chuck 11 are positive and negative poles of each other.

[0026] It should be noted that the drive magnetic chuck 14 and the driven magnetic chuck 11 achieve non-contact power transmission through magnetic coupling. When the drive magnetic chuck 14 is driven to rotate outside the tower body 101 by the rotating rod 15, the rotating magnetic field it generates attracts and drives the driven magnetic chuck 11 inside the tower body 101 to rotate synchronously. This design realizes the transmission of power from the outside to the inside of the tower body 101, while ensuring the complete sealing of the tower body 101 and avoiding the leakage risk that may be caused by the need for dynamic seals.

[0027] Specifically, the end of the mounting rod 12 away from the driven magnetic chuck 11 is rotatably connected to the inner wall of the tower body 101.

[0028] It should be noted that this setup creates a stable rotational support structure.

[0029] Specifically, the scraper 13 is located directly below the support filter 102, and the top of the scraper 13 is in contact with the support filter 102.

[0030] Specifically, the inner top wall of the sealing cover 104 is fixedly connected with two fixing rods 16, and a pressing filter 17 is fixedly connected between the bottom ends of the two fixing rods 16. The pressing filter 17 is the same size as the supporting filter 102.

[0031] It should be noted that the compression filter 17 applies a slight compressive force to the adsorbent bed, which helps to maintain the stability of the adsorbent bed and reduce the loosening of adsorbent particles caused by the periodic switching of airflow.

[0032] Specifically, the bottom of the inner side of the frame 2 is provided with an opening that matches the connecting block 6, and the connecting block 6 is slidably connected to the inner side of the opening.

[0033] The working principle of the above embodiments is as follows:

[0034] The operator aligns the sealing cap 104 with the top opening of the tower body 101 and places it stably. At this time, the locking rods 8 on the connecting plates 7 on both sides of the sealing cap 104 will initially align with the inlet of the connecting cylinder 9 on the side of the tower body 101. The operator rotates the operating wheel 4 clockwise. The operating wheel 4 drives the threaded rod 3 fixed to it to rotate synchronously in the frame 2. The rotating threaded rod 3 drives the threaded block 5 that is threaded to it to move towards the connecting cylinder 9. The threaded block 5 drives the connecting plate 7 and the locking rod 8 to move towards the connecting cylinder 9 through the connecting block 6, so that the locking rod 8 is finally fully inserted into the connecting cylinder 9, thereby completing the connection between the sealing cap 104 and the tower body 101. The filter screen 17 also compacts the adsorbent body 103 in this process.

[0035] The operator rotates the operating wheel 4 counterclockwise, which drives the threaded rod 3 to reverse and drives the threaded block 5 to gradually move away from the connecting cylinder 9. The threaded block 5 pulls the locking rod 8 out of the connecting cylinder 9 through the connecting block 6 and the connecting plate 7. The operator can then lift and remove the sealing cover 104 to disconnect the sealing cover 104 from the tower body 101.

[0036] When it is necessary to clean the support filter 102, rotate the rotating rod 15, which in turn drives the rotation of the transmission magnetic chuck 14. Since the magnetic poles of the transmission magnetic chuck 14 and the driven magnetic chuck 11 inside the tower body 101 are positive and negative poles respectively, the rotating magnetic field of the transmission magnetic chuck 14 will penetrate the wall of the tower body 101 and drive the driven magnetic chuck 11 inside to rotate synchronously. The rotation of the driven magnetic chuck 11 drives the mounting rod 12 fixedly connected to it to rotate. The mounting rod 12 then drives the scraper 13 fixedly connected to it to rotate. The rotating scraper 13 scrapes the bottom surface of the support filter 102.

[0037] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented.
