Description

Technical Field

[0001] The present application relates to the field of dyeing machines, and in particular to a detachable heat exchange device for a dyeing machine. Background Art

[0002] A dyeing machine is a device used for dyeing textiles, which can apply dyes evenly to textiles to achieve a dyeing effect.

[0003] The dyeing machine usually consists of a dyeing tank, a circulation system, a control system and a heating system. When working, the textile to be dyed is placed in the dyeing tank, and an appropriate amount of dye and auxiliaries are added. The heating system is started, and the dye and textile in the dyeing tank are heated to a certain temperature. The circulation system is started to spray the dye evenly onto the textile. At the same time, various parameters are adjusted through the control system to ensure the stability and effect of the dyeing process. When the dyeing is completed, the heating system is turned off and the cooling device is started to cool the dyeing tank.

[0004] When natural gas is used to heat the dye solution, it is usually necessary to pass the flue gas after combustion to the heat exchange tube of the water exchange tank for waste heat recovery before discharge. After long-term use, the heat exchange tube in the water exchange tank is easily blocked due to flue gas deposition and the small diameter of the heat exchange tube. When the tube is blocked, the end cover of the water exchange tank needs to be removed and the heat exchange tube needs to be taken out for cleaning. However, the end cover is usually fixedly connected to the water exchange tank by bolts, and the removal and replacement operation is inconvenient. Summary of the invention

[0050] The implementation principle of a detachable heat exchange device for a dyeing machine in an embodiment of the present application is as follows: the smoke from the smoke pipe 15 passes through the end cover 2 on one side and is transported through the heat exchange tube 14. The smoke from the heat exchange tube 14 passes through the end cover 2 on the other side and is sent out from the smoke pipe 15 on the other side. Water enters the box body 1 through the water inlet 12, and the heat exchange tube 14 exchanges heat with the water in the box body 1 and is sent out from the water outlet 13. When the heat exchange tube 14 needs to be replaced, the top block 62 is pressed into the limiting groove 24, and the connecting ring 42 is slidably pushed to drive the limiting ring 31 to move to the accommodating chamber 171. At this time, the top block 62 is pushed by the push spring 61 to press against one side of the connecting ring 42, and the rotating ring 51 is rotated until the insertion rod 52 and the abutment block 311 are separated, and the end cover 2 is pulled until the clamping plate 211 is disengaged from the box body 1. At this time, the end cover 2 is removed, and then the heat exchange tube 14 is removed and replaced. After replacement, one end of the end cover 2 is slidably inserted into the outer wall of the box body 1. At this time, the rotating ring 51 is rotated until the insertion rod 52 is inserted into the abutment block 311. When the end cover 2 slides, it pushes the limit ring 31 to slide to the accommodating chamber 171, and the clamping plate 21 is clamped at the same time. At this time, the top block 62 is pressed into the limit groove 24, and the limit spring 32 pushes the limit ring 31 to drive the connecting ring 42 to move to the other side of the top block 62. At this time, the push spring 61 pushes one side of the top block 62 to press against the other side of the connecting ring 42, and the end cover 2 is installed.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
