This not only results in enormous energy waste but also exacerbates environmental heat pollution problems.

[0003] According to the authorized announcement number CN217083257U, a waste heat recovery device for textile printing and dyeing is disclosed, including a waste heat recovery box. A waste heat recovery pipe is connected to the top of one side of the waste heat recovery box. A sealing flange is fixedly installed at the top of one side of the waste heat recovery pipe. A connection and fastening groove is opened on the surface of the sealing flange. A preliminary filter screen is detachably installed inside one side of the waste heat recovery box. A first disassembly handle is fixedly connected to the top of one side of the preliminary filter screen. A precision filter is opened on one side of the preliminary filter screen.

[0004] In the process of developing this utility model, the inventors discovered that at least the following problems remain unresolved in the prior art. The aforementioned example, through the cooperation of a preliminary filter, a first disassembly handle, a precision filter, and a second disassembly handle, effectively filters impurities in the hot air during waste heat recovery, specifically the lint on the fabric surface, preventing the accumulation of impurities inside the device. However, during use, the lint in the hot air adheres to the outside of the filter, easily affecting its normal operation; repeated disassembly and cleaning of the filter by operators increases their workload and necessitates frequent shutdowns, impacting the normal use of the equipment.

[0005] Therefore, we propose a waste heat recovery device for textile printing and dyeing, which can automatically adjust the filtration position of the filter cartridge and automatically clean the threads on the outside of the filter cartridge. Utility Model Content

[0018] Please see Figures 1-2 This utility model provides a technical solution: a waste heat recovery device for textile printing and dyeing, including a recovery cylinder 1, a waste heat connecting pipe 11 that is installed through and fixedly installed in the middle of the inner wall of one side of the recovery cylinder 1, a waste heat recovery pipe 12 that is fixedly installed at the upper end of the recovery cylinder 1 away from the waste heat connecting pipe 11, a filter cylinder 13 that is provided inside the recovery cylinder 1, filter holes 14 that are equidistantly opened on the outer side of the filter cylinder 13, and an adjustment mechanism for adjusting the filtration position of the filter cylinder 13, and a cleaning mechanism for automatically cleaning the filter holes 14. The adjustment mechanism includes a drive motor 2, a drive pipe 15 that is vertically installed through and fixedly installed in the middle of the inner wall of the top of the filter cylinder 13, the shaft end of the drive motor 2 that is fixedly connected to the top end of the drive pipe 15, and the drive motor 2 that is fixedly connected to the middle of the upper surface of the recovery cylinder 1.

[0019] In this technical solution, hot air can be introduced into the recovery cylinder 1 through the waste heat connecting pipe 11. The filter holes 14 opened on the outside of the filter cylinder 13 can filter the filaments in the hot air. The corresponding controller controls the drive motor 2 to work, and the drive pipe 15 can drive the filter cylinder 13 to rotate stably in the recovery cylinder 1. This makes it easy to adjust the filtration position of the filter cylinder 13 and prevent impurities in the hot air from accumulating on one side of the filter cylinder 13, which would affect the filtration effect of the filter cylinder 13.

[0020] In this embodiment, the cleaning mechanism includes a brush strip 21. The cleaning end of the brush strip 21 is attached to the outer side of the filter cartridge 13, and the size of the brush strip 21 and the filter cartridge 13 are matched. A mounting groove 24 is vertically opened through the side of the recovery cylinder 1 away from the waste heat connecting pipe 11. The mounting groove 24 is movably connected to the brush strip 21. A sealing plate 25 is fixedly connected to the end of the brush strip 21 placed on the outer side of the recovery cylinder 1. The sealing plate 25 is sealed to the outer side of the recovery cylinder 1 by bolts. A funnel-shaped collection groove 22 is opened through the inner wall of the bottom end of the recovery cylinder 1. A plug 23 is detachably installed at the bottom end of the collection groove 22.

[0021] In this technical solution, a brush strip 21 is vertically installed on the side of the recovery cylinder 1 away from the waste heat connecting pipe 11. The cleaning end of the brush strip 21 is in contact with the outer side of the filter cylinder 13. When the drive motor 2 drives the filter cylinder 13 to rotate and adjusts the relative position of the filter hole 14 and the waste heat connecting pipe 11, the brush strip 21 can automatically clean the filaments generated by filtration on the outer side of the filter cylinder 13, further improving the filtration effect of the filter cylinder 13. Opening the plug 23 makes it convenient for staff to clean the filaments in the collection tank 22. When it is necessary to replace the brush strip 21, the bolts on the outer side of the sealing plate 25 are removed, and the brush strip 21 inside the installation groove 24 can be pulled out.

[0022] In this embodiment, a connecting groove 17 is provided in the middle of the top of the recovery cylinder 1. The drive pipe 15 is rotatably connected to the inner wall of the connecting groove 17 through a sealed bearing. Air inlets 16 are provided at equal intervals on the outer side of the drive pipe 15. The connecting groove 17 is connected to the drive pipe 15 through the air inlets 16. The air inlet of the waste heat recovery pipe 12 is connected to the connecting groove 17.

[0023] In this technical solution, the hot air filtered by the filter cartridge 13 enters the connecting groove 17 through the air guide port 16 opened on the outside of the drive tube 15. Since the air inlet of the waste heat recovery pipe 12 is connected to the connecting groove 17, the further filtered hot air is discharged through the waste heat recovery pipe 12 to the corresponding heat exchange box (not shown in the figure) for heat exchange operation.

[0024] When a waste heat recovery device for textile printing and dyeing is used, the hot air to be recovered can be introduced into the recovery cylinder 1 through the waste heat connecting pipe 11. The filter holes 14 on the outside of the filter cylinder 13 can filter the filaments in the hot air. The filtered hot air enters the connecting groove 17 through the air guide port 16 on the outside of the drive pipe 15, and is discharged into the corresponding heat exchange box through the waste heat recovery pipe 12 for heat exchange. The drive motor 2 is controlled by the corresponding controller to drive the filter cylinder 13 to rotate stably in the recovery cylinder 1 through the drive pipe 15, which facilitates the adjustment of the filter position of the filter cylinder 13. At the same time, the brush strip 21 on the side of the recovery cylinder 1 away from the waste heat connecting pipe 11 can automatically clean the filaments generated by the filter on the outside of the filter cylinder 13. Opening the plug 23 makes it convenient for the staff to clean the inside of the collection groove 22. The brush strip 21 cleans the filaments generated by the filter cylinder 13. When the brush strip 21 needs to be replaced, the bolts on the outside of the sealing plate 25 are removed, and the brush strip 21 on the inside of the mounting groove 24 can be pulled out.
