Description

Technical Field

[0001] The utility model relates to the technical field of air dryers, and particularly relates to a filtering mechanism for a compressed air dryer. Background Technique

[0002] Compressed air dryers are divided into refrigerated compressed air dryers, which use the principle of cooling air to reduce the air temperature, and separate the moisture in the wet air by condensation to obtain relatively dry air. Adsorption compressed air dryers use the principle of pressure swing adsorption. When wet air passes through the adsorbent, the moisture is adsorbed by the adsorbent to obtain dry air.

[0003] A compressed air dryer water storage tank disclosed in Chinese Patent CN218516330U includes a machine shell and a dryer main body. A recovery mechanism is arranged inside the machine shell, and a filtering mechanism is arranged inside the machine shell. The recovery mechanism includes a recovery box fixedly connected to the inner top wall of the machine shell. An electric push rod is fixedly installed inside the recovery box. The filtering mechanism includes a water storage tank fixedly connected to the inner bottom wall of the machine shell. A driving motor is fixedly connected to the top of the water storage tank. A rotating shaft is fixedly connected to the output shaft of the driving motor. A support rod is fixedly connected to the outside of the rotating shaft. A cleaning scraping rod is fixedly connected to one end of the support rod away from the rotating shaft.

[0004] When the above-mentioned existing compressed air dryer water storage tank is in use, the moisture in the air is adsorbed by the water-absorbing cotton. When it is necessary to squeeze out the moisture on the water-absorbing cotton, the staff needs to start the electric push rod to squeeze the water-absorbing cotton; it cannot automatically squeeze the water-absorbing cotton when the dryer starts and stops, and manual control is still required, which is likely to cause the situation that the staff forgets to squeeze the water from the water-absorbing cotton, resulting in the water-absorbing cotton being attached with water for a long time, which in turn causes bacteria to breed, and further causes the drying gas to have an abnormal smell during the next drying gas operation.

[0030] The installation plate 11 is in contact with the inner wall of the recovery box 10.

[0031] Water-absorbing sponges 19 are respectively fixedly connected to both sides of the installation plate 11. Water squeezing plates 26 are slidably installed on both sides of the installation plate 11 in a limited manner. The water squeezing plates 26 are arranged outside the corresponding water-absorbing sponges 19 and squeeze the water-absorbing sponges 19. A linkage assembly is arranged between the water squeezing plates 26 and the installation plate 11.

[0032] The linkage assembly includes a second roller 13, a second rope 14, a second fixing block 15, a first roller 16, a first rope 17, and a first fixing block 18.

[0033] The second roller 13 is fixedly installed at the top end of one side of the installation plate 11. The second rope 14 is fixedly connected to the upper end surface of the water squeezing plate 26 on the same side. A wire hole 22 is formed at the top end of the installation plate 11.

The first rope 17 bypasses the first roller 16 and is fixedly connected to the corresponding first fixing block 18.

[0035] Sliding grooves 24 are respectively formed on the side wall of the installation plate 11 corresponding to both ends of the water squeezing plate 26. Both ends of the water squeezing plate 26 are respectively slidably installed inside the sliding grooves 24. First springs 12 are respectively fixedly connected to the top ends inside the sliding grooves 24. The other ends of the first springs 12 are fixedly connected to the upper end surfaces of the corresponding water squeezing plates 26.

[0036] Limit rods 25 are fixedly installed on the inner walls of the sliding grooves 24. Grooves are respectively formed on the water squeezing plates 26 corresponding to the limit rods 25. The limit rods 25 are slidably connected to the corresponding grooves.

[0037] At the upper and lower ends of the side wall of the dryer main body 9, an air inlet pipe 8 and a return pipe 6 are fixedly connected respectively. The air inlet pipe 8 is internally communicated with the recovery box 10. The return pipe 6 is internally communicated with the filter box 5. At the bottom end of the other side of the dryer main body 9, an air extraction pipe 20 is fixedly connected, and the air extraction pipe 20 extends to the outside of the machine shell 1.

[0038] At the top end of the filter box 5, a connecting pipe 7 is fixedly connected, and the connecting pipe 7 is fixedly connected to the side of the lower end face of the recovery box 10 away from the dryer main body 9. At the upper and lower sides of the side wall of the filter box 5, a water inlet pipe 3 and a drain pipe 4 are fixedly connected respectively, and both the water inlet pipe 3 and the drain pipe 4 extend to the outside of the machine shell 1.

[0039] On the side wall of the recovery box 10 away from the dryer main body 9, an air outlet pipe 2 is fixedly connected, and the air outlet pipe 2 extends to the outside of the machine shell 1.

[0040] Working principle:

[0041] When the dryer main body 9 is started, gas enters the recovery box 10 from the air inlet pipe 8 and impacts the mounting plate 11, thereby causing the mounting plate 11 to slide along the slideway 23 in the direction close to the air outlet pipe 2. At this time, the second spring 21 is stretched and deformed. Since one end of the rope 17 is fixedly connected to the first fixed block 18, the first roller 16 gradually moves away from the first fixed block 18, causing the rope 17 to pull the water squeezing plate 26 on one side to move upward.

[0042] At the same time, one end of the rope 14 is fixed to the second fixed block 15, and the second roller 13 gradually moves away from the second fixed block 15. Therefore, the rope 14 pulls the water squeezing plate 26 on the other side to move upward through the second roller 13. At this time, the first spring 12 in the chute 24 is compressed. As the mounting plate 11 moves, the water squeezing plates 26 on both sides perform a water squeezing operation on the water absorption sponge 19. The water in the water absorption sponge 19 is squeezed out, preventing the water absorption sponge 19 from still adsorbing water, which may cause the problem of low processing efficiency of the water absorption sponge 19 for humid gas during the operation of the dryer main body 9, and improving the processing effect of the water absorption sponge 19 on humid gas.

[0043] The processed dry gas is discharged through the air outlet pipe 2.

[0044] When the dryer main body 9 is closed, there is no longer gas impacting the surface of the mounting plate 11. The second spring 21 resumes deformation and drives the mounting plate 11 to slide away from the air outlet pipe 2. At this time, since the first roller 16 and the second roller 13 gradually approach the first fixing block 18 and the second fixing block 15, the water squeezing plates 26 on both sides move downward under the action of the first spring 12. Thus, when the dryer main body 9 stops operating, the water squeezing plates 26 on both sides automatically squeeze the water-absorbing sponge 19, preventing the water-absorbing sponge 19 from being left with water for a long time due to forgetting to squeeze it when the machine stops, which may cause bacteria to breed. Furthermore, it avoids the situation where the drying gas has an odor during the next drying gas operation, improving the quality of the drying gas of the equipment.

[0045] It should be noted that the water squeezing plates 26 on both sides cooperate to squeeze the water-absorbing sponge 19, and the squeezed water enters the filter box 5 through the connecting pipe 7 for filtration. The filtered water flows back into the dryer main body 9 through the return pipe 6.

[0046] The functions of the water inlet pipe 3 and the drain pipe 4 are to inject water into the filter box 5 from the water inlet pipe 3 and drain the waste water in the filter box 5 from the drain pipe 4 when the filter box 5 needs to be cleaned.

[0047] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of the present invention.
