Description

Technical Field

[0001] This utility model relates to the field of artificial leather processing technology, specifically to an artificial leather processing waste gas purification device. Background Technology

[0002] In leather production, the process begins by removing unwanted materials such as hair, epidermis, fat, and subcutaneous tissue from the raw hide, loosening the collagen fibers, and then tanning to transform the raw hide into leather. Finally, leather finishing and splitting are performed using a series of leather chemicals and various mechanical processes to obtain leather with different uses. During this process, a large amount of production auxiliaries, mixed with the odors emitted by the leather itself and dust, create a foul odor that permeates the air, irritating human senses and causing aversion. Some harmful substances in the gas directly endanger human health. This not only creates a very poor production environment but also seriously affects the surrounding environment of the production plant. Furthermore, replacing the filter element requires disassembling the external side panels, and the equipment must be shut down during the replacement process, making the process cumbersome. Therefore, we propose a waste gas purification device for artificial leather processing. Utility Model Content

A linkage shaft is fixedly connected to the middle of one side of the replacement frame, and an impeller in the backup passage is fixedly connected to one end of the linkage shaft. When the purification component at the purification outlet becomes blocked, the impeller is rotated under air pressure, switching the purification component.

[0005] Optionally, the diameter of the end of the purification outlet and the main pipeline connected to the purification component is smaller than the diameter of the purification component and is in contact with the end of the purification component. Similarly, the diameter of the end of the backup outlet and the backup passage connected to the purification component is smaller than the diameter of the purification component and is in contact with the end of the purification component.

[0006] Optionally, the main body of the purification equipment has an installation port and a material pusher on one side.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 6A purification device for exhaust gas from artificial leather processing includes a main body 1. The main body 1 contains a purification component 6 for filtration, which purifies the air (this is existing technology and will not be described in detail here). One side of the main body 1 has a purification outlet 2 and a backup outlet 3. A replacement frame 7 is connected to the main body 1 via a pivot pin, allowing the replacement frame 7 to rotate in a fixed position on the main body 1. This rotation drives the purification component 6 to rotate and switch positions. Multiple purification components 6 are installed on the replacement frame 7, with each purification outlet 2 and backup outlet 3 corresponding to one of the purification components 6. The other side of the main body 1 has an air inlet 10. Inside the air inlet 10 are a main pipeline 12 and a backup passage, both connected to the air inlet 10. The purification outlet 2 and backup outlet 3... The outlet 3 corresponds to the main pipeline 12 and the backup passage, respectively. A linkage shaft 8 is fixedly connected to the middle of one side of the replacement rack 7. One end of the linkage shaft 8 is fixedly connected to the impeller 9 in the backup passage. When the purification component 6 at the purification outlet 2 becomes blocked, the impeller 9 is driven to rotate under the action of air pressure, switching the purification component 6. Then, during normal filtration, air can enter the purification component 6 from the main pipeline 12 for purification. After filtering the dust carried in the air for a long time, the purification component 6 at the purification outlet 2 will become blocked, affecting the air intake, thus allowing the air to enter the backup passage. When the air passes through the drive groove 15, it drives the impeller 9 to rotate, which in turn drives the linkage shaft 8 to rotate. Driven by the linkage shaft 8, the replacement rack 7 can rotate to quickly replace the purification component 6.

[0022] Please see Figures 1 to 6 The diameter of the ends of the purification outlet 2 and the main pipeline 12 that connect to the purification component 6 is smaller than the diameter of the purification component 6 and are in contact with the end of the purification component 6. The diameter of the ends of the backup outlet 3 and the backup passage that connect to the purification component 6 is smaller than the diameter of the purification component 6 and are in contact with the end of the purification component 6, thereby enabling the purification component 6 at the purification outlet 2 and the backup outlet 3 to rotate and switch stably.

[0023] Please see Figures 1 to 6 The main body 1 of the purification equipment has an installation port 4 and a push port 5 on one side. The purification outlet 2, the spare outlet 3, the installation port 4, and the push port 5 are arranged in a circular pattern. The diameter of the installation port 4 is larger than the diameter of the purification component 6, so that the purification component 6 can be installed on the replacement frame 7 through the installation port 4, so as to reserve one purification component 6 in advance, thereby ensuring the smooth replacement of the purification component 6. The diameter of the push port 5 is smaller than the diameter of the purification component 6, so that the purification component 6 can be pushed from the push port 5, which facilitates the disassembly of the purification component 6.

[0024] Please see Figures 1 to 6The bottom of the main body 1 of the purification equipment is provided with a discharge trough 13 that can be connected to the push port 5. The diameter of the discharge trough 13 is larger than the diameter of the purification component 6. The purification component 6 can be pushed through the push port 5, so that the purification component 6 can be disassembled from the replacement frame 7 and moved into the discharge trough 13 for discharge.

[0025] Please see Figures 1 to 6 The backup passage includes a backup inlet pipe 11, a drive trough 15, and a backup outlet pipe 14 connected in sequence. The drive trough 15 is circular, and the outer side of the impeller 9 is in contact with the inner wall of the drive trough 15. The impeller 9 can rotate within the drive trough 15. The backup inlet pipe 11 is connected to the air inlet 10, and the backup outlet pipe 14 corresponds to the purification outlet 2.

[0026] Please see Figures 1 to 6 The backup outlet pipe 14 has a tapered structure that gradually decreases in size from the purification component 6 to the impeller 9. A cross 16 is fixedly connected to the inner wall of the tapered structure of the backup outlet pipe 14. A valve plate 17 for one-way closure of the backup outlet pipe 14 is movably connected to the middle of the cross 16. The backup outlet pipe 14 can be opened by moving the valve plate 17. The end of the valve plate 17 near the purification component 6 is in contact with the inner wall of the backup outlet pipe 14. The other end of the valve plate 17 passes through the middle of the cross 16 and is fixedly connected to a spring 18. One end of the spring 18 is fixed to the cross 16, and the other end of the valve plate 17 has a smaller diameter than the cross 16 and does not contact the inner wall of the backup outlet pipe 14. Under the action of the spring force of the spring 18, the valve plate 17 can remain in a closed state for a long time. When the purification component 6 at the purification outlet 2 is blocked, the valve plate 17 can be opened by the air pressure.

[0027] In summary, this artificial leather processing exhaust gas purification equipment, during use, introduces purified air through the air inlet 10, and then through the main pipeline 12 into the purification component 6 corresponding to the purification outlet 2, thus purifying the air. After prolonged filtration of dust carried in the air, the purification component 6 at the purification outlet 2 will become clogged, affecting the air intake. This allows the air to enter the backup inlet pipeline 11, pushing the valve plate 17 to open the backup outlet pipeline 14. When the air passes through the drive groove 15, the impeller 9 rotates under the push of the air, which in turn drives the replacement frame 7 to rotate. Driven by the replacement frame 7, the purification component 6 at the backup outlet 3 can be quickly switched to the purification outlet 2. At the same time, the purification component 6 at the installation port 4 switches to the backup outlet 3, and the purification component 6 at the purification outlet 2 switches to the push port 5. The purification component 6 is filled by pushing the installation purification component 6 into the installation port 4, and the purification component 6 can be disassembled from the discharge trough 13 by pushing the purification component 6 from the push port 5.
