Description

Technical Field

[0001] The utility model relates to the field of dryers, in particular to a multi-stage purification refrigeration dryer. Background Art

[0002] A refrigerated dryer is an air dryer that uses physical principles to freeze the moisture in compressed air to below the dew point, causing it to precipitate from the air. The refrigerated dryer has a built-in drying unit, which is mainly composed of an evaporator assembly, a refrigeration compressor and a heat dissipation copper tube.

[0003] The existing refrigerated dryer needs to filter the inhaled air during the suction process of the compressor. The existing filtering method mainly relies on an air filter element, which is a relatively simple filtering method. Moreover, the filtration efficiency of the air filter element will decrease after long-term use, so the air filter element needs to be replaced regularly. However, the existing air filter element is difficult to install and remove, and is cumbersome to replace. In addition, the refrigerated dryer needs to be stopped during the replacement process, which wastes a lot of time and affects the working efficiency of the refrigerated dryer. Utility Model Content

[0033] Working principle of this utility model:

[0034] Refer to the instruction manual Figure 1-5 When the multi-stage purification refrigeration dryer of the present invention is in use, the outside air is sucked into the first air collecting box 9 through the air inlet 18, and the outside air is preliminarily filtered by the filter 19 provided on the inner wall of the air inlet 18. The outside air enters the purification chamber 11 through the air guide hole 17 opened on the top of the purification box 8. The air filter element 16 in the purification chamber 11 will further filter the gas and clean the inhaled gas. After passing through the air filter element 16, the gas in the purification chamber 11 will enter the second air collecting box 10 through the positioning pipe 15 and the docking pipe 20. The gas in the second air collecting box 10 is sucked into the dryer body 1 through the air inlet pipe 24 for gas drying.

[0035] When the air filter element 16 needs to be replaced after long-term use, it is only necessary to close the valve 21 on the corresponding connecting pipe 20 of the designated air filter element 16, and then open the sealing door 22 through the door handle 23. It is only necessary to lift the air filter element 16 upwards, and the outer wall of the top of the air filter element 16 squeezes the spring 13 through the squeezing ring 14, and the bottom of the air filter element 16 moves out from the top of the positioning tube 15. Then the air filter element 16 is taken out, which is convenient for disassembling the air filter element 16. After the air filter element 16 is cleaned, the air filter element 16 is aligned with the positioning column 12 and moved upwards, and then the bottom of the air filter element 16 is aligned with the positioning tube 15 and released. The spring 13 squeezes the air filter element 16 downwards through the squeezing ring 14 to fix the air filter element 16. After the air filter element 16 is installed, the sealing door 22 is closed through the door handle 23, and then the valve 21 is opened.

[0036] The utility model not only realizes the rapid installation and disassembly of the air filter element 16, but also does not affect the continued operation of the other air filter elements 16 during the replacement process. The air filter element 16 can be replaced during the operation of the dryer body 1, thereby improving the working efficiency of the dryer.
