Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to a dryer for a refrigeration unit. Background Art

[0002] Refrigeration units mostly use Freon as refrigerant, which has strong water absorption and requires special lipid lubricant. Lipid lubricant is also very easy to absorb water. During the routine inspection and maintenance work, it is inevitable that water will be enriched in the refrigeration system, which will not only accelerate the decomposition of the compressor oil, but also cause ice blockage, resulting in the compressor being unable to refrigerate. The traditional method of dealing with ice blockage is to stop the machine and extract the refrigerant for water separation. This operation will not only cause a large loss of refrigerant, but also affect the stable operation of the system.

A first threaded joint 5 is plugged and fixed at the center of the left side of the first shell 1, and a second threaded joint 6 is plugged and fixed at the center of the right side of the second shell 2.

[0020] The traction mechanism includes a sleeve 19, and the sleeve 19 is slidably connected to the inner cavity of the second shell 2. The inner diameter length of the sleeve 19 is consistent with the outer diameter length of the sleeve 4. The inner cavity of the sleeve 19 is slidably connected with a threaded rod 18. A threaded hole adapted to the threaded rod 18 is provided on the right side of the second shell 2. One end of the threaded rod 18 passes through the inner cavity of the threaded hole and is fixedly connected to a crank 20. The other end of the threaded rod 18 is fixedly connected to a connector 16, and two connecting rods 17 distributed up and down are fixedly connected to the connector 16. , and the other end of the connecting rod 17 is fixedly connected to the inner wall of the sleeve 4, the outer wall of the threaded rod 18 is sleeved with an extrusion spring 21, and the two ends of the extrusion spring 21 are respectively fixedly connected to the sleeve 19 and the right wall of the inner cavity of the second shell 2.

[0023] Working principle: When the utility model is in use, when the desiccant needs to be replaced, the two cranks 20 are rotated in opposite directions at the same time, and the threaded rod 18 is driven to rotate, so that the connector 16 on the side to be replaced pulls the sleeve 4 to move horizontally to the right and extends into the inner cavity of the sleeve 19. At the same time, the sleeve 4 storing the new desiccant can be screwed out from the inner cavity of the sleeve 19 and sleeved on the outer wall of the hollow tube 11. After the sleeve 4 is completely separated from the hollow tube 11, the pull ring 28 is pulled to drive the pull rod 27 to separate from the inner cavity of the annular groove 13, so that the hollow tube 11 can be removed from the first circular hole 7, and then the new desiccant can be refilled. Into the inner cavity of the hollow cylinder 11, at the same time, by inserting the pull rod 27 into the inner cavity of the annular groove 13 on the newly replaced hollow cylinder 11, the hollow cylinder 11 can be locked to improve the stability of the dryer during use, and the liquid refrigerant is passed through the desiccant in the inner cavity of the hollow cylinder 11 to separate the moisture in the refrigeration system of the refrigeration unit. The moisture in the refrigeration system can be separated when the refrigeration unit is running, effectively reducing the water content of the refrigeration unit, ensuring the stable operation of the unit, reducing the loss of refrigerant, and avoiding maintenance losses. Through the arrangement of double hollow cylinders 11, the desiccant can be replaced without stopping the machine, which is more efficient and convenient to use.
