Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange equipment, in particular to a heat exchange device for a textile setting machine. Background Art

[0002] The setting machine is a key equipment for textile printing and dyeing finishing. During the heat setting process of the fabric, the temperature is high, so a large amount of high-temperature gas is generated in the oven of the setting machine. The high-temperature gas contains pollutants such as organic oil, dyes, dye additives, lubricating oil, fiber particles, etc. The molecular clusters of oil mist volatilized in the atmosphere can inhale particles with complex composition and strong adsorption capacity. It is the "carrier" and "catalyst" of various pollutants, and sometimes it can become a collection of various pollutants.

[0003] Patent publication number CN216245719U proposes a heat exchanger, including an air-to-air heat energy exchange mechanism and a cleaning mechanism both located in a heat exchange box body, the air-to-air heat energy exchange mechanism includes an air-to-air heat exchange box assembly, an air outlet pipeline and a blower, the cleaning mechanism includes a plurality of cleaning branches, the air-to-air heat exchange box assembly is located on one side of the cleaning branch, one end of the air-to-air heat exchange box assembly is fixedly connected to the blower, and the other end is fixedly connected to the air inlet of an external device through an air outlet pipeline, and the blower and the cleaning mechanism are both connected to the controller by signal. This heat exchanger has a simple structure and is provided with two-stage filtration, which can not only block most of the dust and fluff in the exhaust gas, reduce unnecessary shutdown and heat energy loss caused by cleaning the dust, reduce the fire hazard caused by excessive dust accumulation and low heat recovery efficiency, intermittent automatic cleaning, save manpower, and reduce the daily maintenance workload of operators. When this structure is actually used, compressed air is used to clean the dust on the surface of the filter. Since the exhaust gas of the setting machine contains a large amount of oil, the oil will adhere dust and other impurities to the filter, and it is difficult to clean the filter with compressed air. At the same time, the oil will also adhere to the heat exchange tube. Since the oil is not easily soluble in water, it is difficult to clean the oil by spraying the heat exchange tube with a spray pipe. For this reason, we provide a heat exchange device for a textile setting machine. Utility Model Content

[0030] See also Figure 2 , Figure 6 , Figure 7 , Figure 8The oil removal mechanism 7 includes a servo motor 71 fixed to the side of the heat exchange box body 1, and a screw 72 is connected to the output shaft of the servo motor 71. The external thread of the screw 72 is sleeved with a thread sleeve 73.

[0031] In summary, when the heat exchange device of the textile setting machine is used, the high-temperature exhaust gas discharged by the setting machine is discharged from the air inlet 11 into the heat exchange box 1, and then the high-temperature exhaust gas passes through the filter 23 for dust removal. When the filter 23 moves to the cleaning mechanism 3, clean water is transported from the water inlet pipe 32 to the cleaning mechanism 3, and the scraper 1 34 is used to scrape off the oil stains adhering to the surface of the filter 23. The cleaning wheel 35 is driven to rotate by the driving motor 2 36, so that the cleaning wheel 35 cleans the oil stains remaining on the surface of the filter 23. At the same time, the solenoid valve 42 is opened to add the degreasing agent in the degreasing agent tank 41 to the cleaning mechanism 3, and the oil stains adhering to the surface of the filter 23 are removed. The oil stains on the surface are dissolved, and the dissolved sewage is discharged from the outlet pipe 33. The filtered exhaust gas enters the gas-to-gas heat exchange mechanism 6 for gas-to-gas heat exchange, and then passes through the gas-to-water heat exchange mechanism 9 for gas-to-water heat exchange. When oil stains are attached to the surface of the gas-to-water heat exchange mechanism 9, the servo motor 71 drives the lead screw 72 to rotate, so that the threaded sleeve 73 and the movable plate 74 move along the lead screw 72, and the threaded sleeve 76 rotates around the lead screw 77 during the movement. The threaded sleeve 76 drives the oil removal ring 75 to rotate, so that the scraper 751 can scrape off the oil stains attached to the surface of the gas-to-water heat exchange mechanism 9.
