The number and combination of cyclones in the multi-stage cyclone separation and high-efficiency filtration dry dust collection device can be flexibly adjusted according to different dust characteristics and working conditions, as well as different high-efficiency filter media.
[0003] The daily production activities in factories such as steel mills and cement plants generate a large amount of dust. If this dust is not cleaned up in a timely manner, factory workers will inhale a large amount of dust during production, which will harm their health. Therefore, dust in factories needs to be cleaned up in a timely manner. In the existing technology, most dust collection devices are single-stage cyclone separation devices. Since the diameter distribution of dust particles in factories is relatively wide, single-stage separation dust collection devices are difficult to clean up the dust in factories effectively. The air discharged by the dust collection devices contains a lot of fine dust particles, which will pollute the air and affect the health of factory workers, causing harm. Utility Model Content

[0014] 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.
[0015] Example: Reference Figure 1 , Figure 2 and Figure 3 A multi-stage cyclone separation and high-efficiency filtration dry dust collection device includes a trolley 1, a dust collection box 2 fixedly connected to the top of the trolley 1, a filter box 3 fixedly connected to the top of the dust collection box 2, a dust collection assembly on the top of the dust collection box 2, the dust collection assembly including a blower body 4 fixedly connected to the top of the dust collection box 2, a first cyclone separator 6, a second cyclone separator 7 and a third cyclone separator 8 fixedly connected to the top of the dust collection box 2 respectively, a first guide pipe 9 fixedly connected between the first cyclone separator 6 and the second cyclone separator 7, a second guide pipe 26 fixedly connected between the second cyclone separator 7 and the third cyclone separator 8, a guide pipe 5 fixedly connected to the top of the dust collection box 2, the guide pipe 5 fixedly connected to the blower body 4, an exhaust pipe 10 fixedly connected to the top of the third cyclone separator 8, a collection assembly inside the dust collection box 2, and a control switch 25 fixedly connected to the outside of the trolley 1, the control switch 25 being electrically connected to the blower body 4. When dust removal is required in the factory via the set-in diversion pipe 5, the staff first aligns the bottom of the diversion pipe 5 with the area to be dusted, then presses the control switch 25 to start the induced draft fan 4. Dust then flows into the induced draft fan 4 from the diversion pipe 5, and the dust-laden air enters the first cyclone separator 6 from the exhaust port of the induced draft fan 4. Large-diameter particles are then thrown against the wall of the first cyclone separator 6 under centrifugal force, lose kinetic energy after collision, and fall down the wall into the ash hopper. The purified gas then enters the second cyclone separator 7 through the first guide pipe 9, repeating the centrifugal separation process to capture smaller-diameter particles. The purified gas then enters the third cyclone separator 8 through the second guide pipe 26, repeating the centrifugal separation process to capture even smaller-diameter particles. Finally, the purified gas is discharged through the exhaust pipe 10. By connecting multiple stages in series, the dust removal device can capture smaller-diameter particles, significantly reducing the particulate matter content of the discharged gas and effectively reducing pollution to the surrounding air.
[0016] refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 The collection assembly includes a first collection box 11, with a second collection box 12 and a third collection box 13 respectively located inside the dust collection box 2. Each of the first, second, and third collection boxes 11 and 12 has a handle 14 fixedly connected to its exterior. The first, second, and third collection boxes 11, 12, and 13 correspond to the ash discharge ports at the bottom of the first cyclone separator 6, second cyclone separator 7, and third cyclone separator 8, respectively. The trolley 1 has several grooves 18 on its inner bottom surface. The bottom of the first collection box 11, the second collection box 12, and the third collection box 13 are respectively provided with two positioning grooves 27. A connecting rod 15 is fixedly connected inside the positioning groove 27. A roller 16 is movably sleeved on the outer circular wall of the connecting rod 15. Several rollers 16 are slidably connected to several sliding grooves 18. The bottom of the first collection box 11, the second collection box 12, and the third collection box 13 are respectively provided with support grooves 17. A limit spring 28 is fixedly connected to the top surface inside the support groove 17. A second locking block 29 is fixedly connected to the bottom of the limit spring 28. Several second locking blocks 29 are movably locked to several sliding grooves 18. With the dust collection box 2 in place, when the dust in the first cyclone separator 6 is full, the staff first opens the door of the dust collection box 2. Then, the staff discharges the dust in the first cyclone separator 6 into the third collection box 13 through the ash discharge port. When too much dust accumulates in the second cyclone separator 7, the staff discharges the dust in the second cyclone separator 7 into the first collection box 11 through the ash discharge port. When too much dust accumulates in the third cyclone separator 8, the staff discharges the dust in the second cyclone separator 7 into the first collection box 11 through the ash discharge port. This reduces the staff's dust removal operation time, avoids increased equipment downtime due to dust removal, and ensures the continuous and efficient operation of the entire dust removal system. With the handle 14 in place, when a large amount of dust accumulates in the first collection box 11, the second collection box 12, or the third collection box 13, the handle 14 is pulled first. Then, the first collection box 11, the second collection box 12, or the third collection box 13 begins to move away from the dust collection box 2. Subsequently, the limiting spring 28 moves closer to the first collection box 11, the second collection box 12, or the third collection box 13. Then, the second locking block 29 moves closer to the first collection box 11, the second collection box 12, or the third collection box 13. Subsequently, the roller 16 moves along the inner wall of the slide 18 away from the dust collection box 2, so that the first collection box 11, the second collection box 12, or the third collection box 13 can be removed from the dust collection box 2. This makes it easier for workers to clean the dust in the first collection box 11, the second collection box 12, or the third collection box 13, greatly reducing the labor intensity of dust cleaning and improving the convenience of the overall operation.
[0017] refer to Figure 1 , Figure 3 and Figure 7 The exhaust pipe 10 has several slots 24 inside, and a filter disc 19 is provided inside the exhaust pipe 10. Several limiting slots 20 are provided on the outer circular wall of the filter disc 19. A fixing block 21 is fixedly connected to the inner circular wall of the limiting slot 20. A telescopic spring 22 is fixedly connected inside the fixing block 21. A first locking block 23 is fixedly connected to the end of the telescopic spring 22 away from the fixing block 21. The first locking block 23 is movably engaged with the slot 24. When air from the third cyclone separator 8 is discharged through the exhaust pipe 10 via the filter disc 19, fine particles in the exhaust pipe 10 are intercepted by the filter disc 19. When the filter holes of the filter disc 19 are clogged with dust, reducing the air discharge capacity of the exhaust pipe 10, the operator removes the filter disc 19, moving it away from the exhaust pipe 10. This causes the telescopic spring 22 to move closer to the filter disc 19, and subsequently, the first locking block 23 moves closer to the filter disc 19, allowing it to be removed. After the operator cleans the filter disc 19, it moves closer to the exhaust pipe 10. The spring 22 moves towards the filter plate 19, and then the first locking block 23 moves towards the filter plate 19. Under the force generated by the deformation of the spring 22, the first locking block 23 moves away from the filter plate 19, so that the first locking block 23 and the slot 24 are locked together. This allows the slot 24 to filter the fine particles in the air discharged from the exhaust pipe 10, making it easy for staff to clean or replace it regularly. This avoids secondary pollution caused by the direct emission of fine dust, and at the same time ensures the unobstructed flow of the exhaust pipe 10, ensuring the long-term stable exhaust effect of the equipment.
[0018] Working principle: Please refer to Figures 1-7 As shown, when dust removal is required in the factory via the set diversion pipe 5, the operator first aligns the bottom of the diversion pipe 5 with the area to be dusted, then presses the control switch 25 to start the induced draft fan 4. Dust then flows into the induced draft fan 4 from the diversion pipe 5, and the dust-laden air enters the first cyclone separator 6 from the exhaust port of the induced draft fan 4. Large-diameter particles are then thrown against the wall of the first cyclone separator 6 under centrifugal force, lose kinetic energy after collision, and fall down the wall into the ash hopper. The purified gas then enters the second cyclone separator 7 through the first guide pipe 9, repeating the centrifugal separation process to capture smaller-diameter particles. The purified gas then enters the third cyclone separator 8 through the second guide pipe 26, repeating the centrifugal separation process to capture even smaller-diameter particles. Finally, the purified gas is discharged through the exhaust pipe 10. By connecting multiple stages in series, the dust removal device can capture smaller-diameter particles, reduce the particulate matter content of the discharged gas, and reduce air pollution.
[0019] With the dust collection box 2 in place, when the dust in the first cyclone separator 6 is full, the staff first opens the door of the dust collection box 2. Then, the staff discharges the dust in the first cyclone separator 6 into the third collection box 13 through the ash discharge port. When too much dust accumulates in the second cyclone separator 7, the staff discharges the dust in the second cyclone separator 7 into the first collection box 11 through the ash discharge port. When too much dust accumulates in the third cyclone separator 8, the staff discharges the dust in the second cyclone separator 7 into the first collection box 11 through the ash discharge port. This reduces the cleaning time for the staff and improves the dust removal efficiency of the first cyclone separator 6, the second cyclone separator 7, and the third cyclone separator 8.
[0020] When a large amount of dust accumulates in the first collection box 11, the second collection box 12, or the third collection box 13, the handle 14 is pulled first. Then, the first collection box 11, the second collection box 12, or the third collection box 13 begins to move away from the dust collection box 2. Subsequently, the limiting spring 28 moves closer to the first collection box 11, the second collection box 12, or the third collection box 13. Then, the second locking block 29 moves closer to the first collection box 11, the second collection box 12, or the third collection box 13. Subsequently, the roller 16 moves along the inner wall of the slide 18 away from the dust collection box 2, so that the first collection box 11, the second collection box 12, or the third collection box 13 can be removed from the dust collection box 2, making it easier for staff to clean the dust in the first collection box 11, the second collection box 12, or the third collection box 13.
[0021] When air from the third cyclone separator 8 is discharged through the exhaust pipe 10 via the filter disc 19, fine particles in the exhaust pipe 10 are intercepted by the filter disc 19. When the filter holes of the filter disc 19 become clogged with dust, reducing the air discharge capacity of the exhaust pipe 10, the operator removes the filter disc 19, moving it away from the exhaust pipe 10. This causes the telescopic spring 22 to move closer to the filter disc 19, and subsequently, the first locking block 23 moves closer to the filter disc 19, allowing it to be removed. After the filter disc 19 is cleaned, it is moved closer to the exhaust pipe 10. Consequently, the telescopic spring 22 moves closer to the filter disc 19, and then the first locking block 23 moves closer to the filter disc 19. Under the force generated by the deformation of the telescopic spring 22, the first locking block 23 moves away from the filter disc 19, so that the first locking block 23 and the locking groove 24 are locked together. This allows the locking groove 24 to filter the fine particles in the air discharged from the exhaust pipe 10, thereby improving the cleanliness of the air discharged from the exhaust pipe 10.
