Description

Technical Field

[0001] This utility model relates to the field of compressed air desiccation technology, and more specifically, to a compressed air desiccation device. Background Technology

[0002] Currently, compressed air produced by air compressors contains a certain amount of moisture, which can cause significant damage to pneumatic components. Therefore, air drying equipment such as dryers and air-water separators are widely used in industries, manufacturing, and medical fields to ensure the dryness and cleanliness of compressed air. Adsorption drying devices generally use cooling, adsorption, membrane separation, and freeze drying methods to remove moisture from compressed air. Adsorption is widely used because it has a relatively simple structure and is fast-acting.

[0003] However, after traditional desiccant devices are used, water tends to accumulate inside the device due to the large amount of water inside the absorbent material. If the water is not drained for a long time, it will not only affect the desiccant drying effect of the next compressed air, but also cause corrosion inside the device.

[0004] Furthermore, the absorbent material is not easy to replace, and with prolonged use, impurities from the compressed air will inevitably accumulate inside, causing blockages and affecting the ventilation effect. Utility Model Content

An air inlet pipe 23 is fixedly disposed on the outer wall of the water storage tank 5. A support leg 26 is fixedly disposed on the outer wall of the water storage tank 5.

[0032] In this embodiment, a sealing groove 12 is provided at the connection position between the cover 10 and the housing 1. A sealing gasket 13 is provided inside the sealing groove 12. The sealing gasket 13 abuts against the inner wall of the sealing groove 12. A flange 14 is provided on the outer wall of both the cover 10 and the housing 1. The two flanges 14 are fixedly installed by bolts.

[0033] More specifically, the user can control the hydraulic push rod 6 to move the first filter plate 7 and the second filter plate 9 upwards to squeeze the water-absorbing sponge 4, thereby quickly squeezing out the water inside and discharging it through the drain pipe 24. Furthermore, by setting the first filter plate 7 and the second filter plate 9 at the upper end of the hydraulic push rod 6, impurities in the compressed air can be filtered to prevent them from accumulating in the water-absorbing sponge 4 and affecting its ventilation effect. The user can disassemble the cover 10 and the housing 1 by removing the bolts on the flange 14, at which point the water-absorbing sponge 4 inside the housing 1 can be removed for easy replacement.

[0034] Please see Figure 1 and Figure 3As an implementation method for adjusting the angle of the elbow 17: an air outlet pipe 15 is fixedly provided on the upper end face of the cover 10, a sealed bearing is provided at the upper end of the air outlet pipe 15, a collar 16 is provided at the outer end of the sealed bearing, the collar 16 is rotatably installed with the air outlet pipe 15 through the sealed bearing, an elbow 17 is fixedly provided on the upper end face of the collar 16, a connecting plate 18 is provided at the other end of the elbow 17, a cylinder 19 is fixedly provided at the bottom of the collar 16, the inner wall of the cylinder 19 is in contact with the outer wall of the air outlet pipe 15, a locking hole 20 is provided on the outer wall of the cylinder 19, a locking pin 21 is provided inside the locking hole 20, the locking pin 21 is threadedly connected to the locking hole 20, and a turning block 22 is fixedly provided at one end of the locking pin 21.

[0035] Specifically, the user can loosen the locking pin 21 by turning the block 22, and then rotate the elbow 17 through the sealed bearing to adjust the air outlet direction of the device, which also makes it easier to connect with pneumatic components in different positions and increases flexibility.

[0037] Specifically, users can open valve 25 to drain the water inside the water tank 5 in a timely manner to prevent accumulation.

[0038] In summary, when using the overall equipment: the user can first connect the compressed gas discharged from the compressor to the air inlet pipe 23. The gas then enters the water storage chamber and the housing 1, and after being filtered by the first filter plate 7 and the second filter plate 9, it enters the absorbent sponge 4. The absorbent sponge 4 then absorbs the moisture in the compressed gas, and finally discharges it through the elbow 17 into the pneumatic device for convenient use. After use, the hydraulic push rod 6 can be controlled to move the first filter plate 7 and the second filter plate 9 upwards, squeezing the absorbent sponge 4 to quickly expel the water inside, which is then discharged through the drain pipe 24 to prevent accumulation from affecting subsequent water absorption. Furthermore, by setting the first filter plate 7 and the second filter plate 9 at the upper end of the hydraulic push rod 6, impurities in the compressed air can be filtered to prevent them from accumulating in the water-absorbing sponge 4 and affecting its ventilation effect. Users can also disassemble the cover 10 and the housing 1 by removing the bolts on the flange 14. At this time, the water-absorbing sponge 4 inside the housing 1 can be taken out for easy replacement. When it is necessary to adjust the installation angle of the elbow 17, the locking pin 21 can be loosened by turning the block 22 first. Then, the elbow 17 can be rotated by the sealed bearing to adjust the air outlet direction of the device. This also facilitates connection with pneumatic components in different positions and increases flexibility.
