A flow hood is installed on one side of the cooler 4, and an electrostatic device 21 and a temperature monitoring probe 22 are installed on the flow hood. A first exhaust pipe 17 is installed on the other side of the flow hood, and a purification and emission mechanism is installed at the other end of the first exhaust pipe 17. The purification and emission mechanism includes a mounting base 18, a filter screen 19, a rubber pad 20, a locking assembly, a torsion assembly, and a protective assembly. An overlap groove is provided on one side of the mounting base 18, and a support body overlaps inside the overlap groove. The rubber pad 20 is embedded in one side of the support body, and the filter screen 19 is installed at the bottom of the support body. At the center of the unit, a locking component is used to lock the position of the filter screen 19, a twisting component is used to release the lock on the filter screen 19, and a protective component is used to seal the operating end of the twisting component. When in use, the device can lock the position of the filter screen 19 through the locking component, release the lock on the filter screen 19 through the twisting component, and seal the operating end of the twisting component through the protective component. A cooler 4 is installed at the end of the exhaust pipe 2 away from the dryer 1. A flow hood is installed on one side of the cooler 4. An electrostatic device 21 and a temperature monitoring probe 22 are installed on the flow hood. The structure is simple and easy to operate, effectively reducing the environmental hazards of exhaust gas emissions, improving the product's smoothness, moisture regain, oil content and other quality standards, and facilitating the quick replacement and assembly of the filter screen 19 by staff, further improving work efficiency.

[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a second exhaust pipe is embedded at the other end of the mounting base 18, and an exhaust hood is installed at the other end of the second exhaust pipe. An exhaust gas index monitoring probe 16 is installed on the exhaust hood. First, the dryer 1 consists of 14 circulation zones. The original dehumidification system was divided into two major zones, 1-5 and 6-14, which had poor dehumidification effect. Now the system has re-planned the dehumidification areas, which are 1-3, 4-6, 7-9, and 10-14. The internal partitions and partitions of the dryer 1 have all been rebuilt and upgraded around the newly planned dehumidification areas. The exhaust pipe 2 has been upgraded to the four newly planned zones. The number of centrifugal fans 3 has been increased to 4 to match the newly planned areas. The exhaust pipes 2 of the four zones are connected to the exhaust outlet. The addition of a cooler 4 can reduce the exhaust gas temperature to meet the emission requirements. The addition of an electrostatic device 21 can treat the oil mist molecules in the exhaust gas to meet the emission requirements. Temperature monitoring probe 22 and exhaust gas index monitoring probe 16 have been added to monitor the exhaust gas emission at all times.

[0024] In this embodiment, as Figure 2 , Figure 3 and Figure 4As shown, the locking assembly includes a mating hole inside the rubber pad 20. A locking block 5 is installed on one side of the bracket body at the mating hole. The outer wall of the locking block 5 fits against the inner wall of the mating hole. A slot is provided on the outer wall of the mounting base 18 corresponding to the mating hole. The locking block 5 and the slot are slidably connected. A locking groove is provided inside the mounting base 18 on one side of the slot. A rotating rod 6 is rotatably connected to the inner side of the locking groove. A locking block 7 is sleeved on the outer side of the rotating rod 6. Then, the bracket body is fitted with the overlapping groove on the mounting base 18, and the rubber pad 20... Contact mounting base 18, push the locking block 5 into the mating hole, and it will enter the inner side of the slot, continuing to squeeze the rubber pad 20. As the rubber pad 20 retracts, the locking block 5 enters the inner side of the locking groove and contacts the locking block 7. The slopes 10 of the two press against each other, forcing the locking block 7 to rotate around the rotating rod 6. The connecting spring 9 is stretched accordingly. After the locking block 5 contacts the abutment plate 11, the slope 10 and the inclined surface press against each other, forcing the abutment rod to drive the reset torsion spring 12 to retract, allowing the abutment plate 11 to completely retract into the retraction groove.

[0025] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, a connecting groove is provided on one side of the locking block 7, and a fixing plate 8 is installed on one side of the inner wall of the locking groove. A connecting spring 9 is installed between the inner wall of the connecting groove and the fixing plate 8. The contact surfaces of the locking block 5 and the locking block 7 are provided with mutually contacting slopes 10. Further, the bracket body is fitted with the overlapping groove on the mounting base 18, the rubber pad 20 contacts the mounting base 18, and the locking block 5 is pushed in through the docking hole and enters the inner side of the groove. The rubber pad 20 is further squeezed. As the rubber pad 20 retracts, the locking block 5 enters the inner side of the locking groove and contacts the locking block 7. The slopes 10 of the two press against each other, forcing the locking block 7 to rotate around the rotating rod 6. The connecting spring 9 is stretched accordingly. After the locking block 5 contacts the abutment plate 11, the slope 10 and the inclined surface press against each other, forcing the abutment rod to drive the reset torsion spring 12 to retract, so that the abutment plate 11 is completely retracted to the inner side of the retraction groove.

[0026] In this embodiment, as Figure 2 , Figure 3 and Figure 4As shown, the locking block 7 has a retraction groove at its slope 10, and an abutment rod is rotatably connected to the inside of the retraction groove. An abutment plate 11 is sleeved on the outside of the abutment rod. A reset torsion spring 12 is installed between the abutment rod and the inner wall of the retraction groove. The locking block 5 has an abutment groove at its slope 10, and an inclined surface corresponding to and fitting the slope 10 is opened on one side of the abutment plate 11. The torsion assembly includes a limiting groove opened on one side of the inner wall of the locking groove. A limiting plate 14 that is slidably connected to the limiting groove is installed at the end of the locking block 7 away from the slope 10. The mounting base 18 has an internal... An extension groove is provided on one side of the locking groove. A knob 15 is installed at one end of the rotating rod 6 that extends into the extension groove. Furthermore, when maintenance or cleaning of the filter screen 19 is required, the knob 15 can be turned to rotate the rotating rod 6, which in turn rotates the locking block 7. The abutment plate 11 is pulled away from the inner wall of the abutment groove. At this time, the rubber pad 20 fully resets and rebounds. The locking block 5 continues to move. After the abutment groove and the retraction groove are misaligned, the abutment plate 11 will no longer be stuck inside the abutment groove. Then the bracket body can be removed to maintain or replace the filter screen 19.

[0027] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, the protective assembly includes a protective cover 23 installed on one side of the mounting base 18. A closed cover 24 overlaps one side of the protective cover 23. A connecting groove is provided on the top side of the protective cover 23. A synchronization block that is slidably connected to the synchronization groove 13 is installed at the bottom end of the closed cover 24. The cross-section of the synchronization block and the synchronization groove 13 is T-shaped. Magnetic components are embedded at the opposite ends of the protective cover 23 and the closed cover 24. The two sets of magnetic components have opposite magnetic properties and attract each other. Furthermore, after the filter screen 19 is assembled, holding the closed cover 24 can drive the synchronization block to slide inside the synchronization groove 13, so that the closed cover 24 and the protective cover 23 fit together. The two sets of magnetic components attract each other and cover the knob 15, preventing the operator from accidentally touching the knob 15 after installation and causing the connected parts to loosen.

[0028] The implementation principle of the hollow fiber drying and dehumidification device in this application embodiment is as follows: The bracket body is attached to the overlapping groove on the mounting base 18, the rubber pad 20 contacts the mounting base 18, and the locking block 5 is pushed in through the docking hole and enters the inner side of the locking groove, continuing to squeeze the rubber pad 20. As the rubber pad 20 retracts, the locking block 5 enters the inner side of the locking groove and contacts the locking block 7. The slopes 10 of the two press against each other, forcing the locking block 7 to rotate around the rotating rod 6. The connecting spring 9 is stretched accordingly. After the locking block 5 contacts the abutment plate 11, the slope 10 and the inclined surface press against each other, forcing the abutment rod to drive the return torsion spring 12 to retract, allowing the abutment plate 11 to completely retract into the retraction groove. Until the abutment groove is close to the retraction groove, the abutment plate 11 is ejected into the inner side of the abutment groove by the return torsion spring 12. At this time, the bracket body is released, and the rubber pad 20 will rebound, causing the locking block 5 to move back to the abutment plate 11. The filter screen 19 is fixed tightly against the inner wall of the abutment groove and installed between the first exhaust pipe 7 and the second exhaust pipe to filter the passing exhaust gas. When the filter screen 19 needs to be inspected, maintained or cleaned, the knob 15 can be turned to drive the rotating rod 6 to rotate, which in turn drives the locking block 7 to rotate. The abutment plate 11 is pulled away from the inner wall of the abutment groove. At this time, the rubber pad 20 is fully reset and rebounds, and the locking block 5 continues to move. After the abutment groove and the retraction groove are misaligned, the abutment plate 11 will no longer be stuck inside the abutment groove. Then the bracket body can be removed to maintain or replace the filter screen 19. After the filter screen 19 is assembled, the closing cover 24 can be held to drive the synchronous block to slide inside the synchronous groove 13, so that the closing cover 24 and the protective cover 23 are attached together. The two sets of magnetic parts attract each other to cover the knob 15, preventing the staff from accidentally touching the knob 15 after installation and causing the connected parts to loosen.

[0029] The control method of this utility model is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
