Technical Field
[0001] This utility model relates to the field of environmental protection dust removal technology, and in particular to an environmental protection dust removal device for a dry powder material production line. Background Technology
[0002] The production of dry powder easily generates a large amount of dust, which not only wastes raw materials but also seriously pollutes the workshop and surrounding environment, endangers the health of employees, and poses an explosion risk. With increasingly stringent environmental protection policies, traditional open production can no longer meet the requirements of clean production. Environmental dust removal devices use technologies such as negative pressure collection and high-efficiency filtration to achieve dynamic closed-loop capture and purification of dust throughout the production process, significantly reducing fugitive emissions, ensuring workplace cleanliness and production safety, and are a necessary technical means to achieve green manufacturing. Currently, pulse-jet baghouse dust collectors are commonly used for dust collection and removal in dry powder production lines. However, when these collectors use jet jets to shake off dust from the filter bags, the shaken-off dust may collide with the sucked-in dust, causing it to remain suspended. This prevents the dust from falling into the collection box immediately, resulting in poor pulse-jet dust removal efficiency. Utility Model Content
[0003] To achieve the above objectives, the present invention adopts the following technical solution: An environmentally friendly dust removal device for a dry powder material production line includes: The dust collector includes a dust collection box and a collection box. A bracket is fixedly installed on the lower side of the dust collection box. An air inlet pipe is fixedly connected to the side wall of the dust collection box, and a dust suction port is fixedly connected to one end of the air inlet pipe. A frame is fixedly connected to the inner side of the dust collection box, and filter bags are fixedly installed on the side wall of the frame. A tube sheet is fixedly installed on the inner side of the dust collection box, and a ventilator is fixedly installed on the side wall of the tube sheet. An air manifold is fixedly installed on the upper side of the dust collection box, and a pulse jet cleaning system is installed on the air manifold. Ventilation openings are provided on the side wall of the dust collection box.
[0004] Preferably, the dust collector is equipped with a circulation switch structure, which includes a fixed frame fixedly connected to the inside of the dust collector. Multiple rotating shafts are rotatably connected to the side wall of the fixed frame. The rotating shafts are arranged in pairs, and a rotating plate is fixedly connected to the outer side of each pair of rotating shafts. The two rotating shafts are connected by a gear assembly. A spur gear I and a spur gear II are rotatably mounted on the side wall of the dust collector, both meshing with the gear assembly. Two drive shafts are rotatably connected to the side wall of the dust collector. A drive motor is fixedly mounted at one end of one of the drive shafts. Circular plates are fixedly sleeved on the outer sides of both drive shafts. A belt is rotatably sleeved on the outer sides of the two circular plates. A spur rack I and a spur rack II are fixedly connected to the side wall of the belt.
[0005] Preferably, a vibration structure is installed on the fixed frame. The vibration structure includes multiple sliders slidably connected to the side wall of the fixed frame. Each of the multiple sliders is fixedly connected to the fixed frame with a spring. Vibration blocks are fixedly connected to the lower side of each of the multiple sliders. Multiple extrusion blocks are fixedly connected to the side wall of each of the multiple rotating plates.
[0006] Preferably, the gear assembly includes two rotating shafts rotatably connected to the side wall of the dust collector, and spur gears are fixedly sleeved on the outer sides of the two rotating shafts, with adjacent spur gears meshing with each other.
[0007] Preferably, a slide rail is fixedly connected to the side wall of the dust collector, and a slide groove is opened on the inner side of the slide rail. Both the first straight rack and the second straight rack are slidably connected to the slide groove.
[0008] Preferably, a reinforcing rod is fixedly connected to the side wall of the bracket.
[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, the rotating plate on the fixed frame can be cyclically switched by the cyclic switch structure, so that the rotating plate is closed during the pulse, thereby reducing the entry of dust-laden gas and avoiding the situation of suspension caused by collision with falling dust, so as to make the pulse shaking effect better. 2. In this utility model, the vibration structure enables the rotating plate to squeeze the vibration block when it rotates downwards and opens, thereby vibrating the rotating plate through the elastic force of the spring, so that the dust remaining on the surface of the rotating plate can fall off, avoiding the situation where a large amount of dust remains on the rotating plate.

[0012] Reference Figures 1-6 An environmentally friendly dust removal device for a dry powder material production line, comprising: The dust collector 1 and the collection box 10 are configured such that the collection box 10 corresponds to the dust outlet on the lower side of the dust collector 1 and can collect the falling dust, thus avoiding environmental pollution. A bracket 2 is fixedly installed on the lower side of the dust collector 1, and a reinforcing rod 27 is fixedly connected to the side wall of the bracket 2. The reinforcing rod 27 and the bracket 2 form a triangular stable structure, which can make the structural strength of the bracket 2 higher. An air inlet pipe 3 is fixedly connected to the side wall of the dust collector 1, and a dust suction port is fixedly connected to one end of the air inlet pipe 3. A frame 4 is fixedly connected to the inside of the dust collector 1, and filter bags 5 are fixedly installed on the side wall of the frame 4. A tube sheet 6 is fixedly installed inside the dust collector 1, which divides the dust collector 1 into an upper layer. The dust collector consists of two parts: a clean air chamber and a lower filter chamber. A venturi tube 7 is fixedly installed on the side wall of the tube sheet 6. An air manifold 8 is fixedly installed on the upper side of the dust collector 1. A pulse jet system 9 is installed on the air manifold 8. The pulse jet system 9 contains multiple jet pipes and pulse valves. By intelligently controlling the opening and closing of the pulse valves, high-pressure gas can be ejected through the jet pipes. Each jet pipe corresponds to a filter bag 5. The ejected gas can accurately enter the filter bag 5 through the venturi tube 7, thereby causing the filter bag 5 to shake. This is existing technology and will not be described in detail. Ventilation openings are opened on the side wall of the dust collector 1, and the filtered clean gas is discharged through the ventilation openings.
[0013] A circulation switch structure is installed on the dust collector 1. The circulation switch structure includes a fixed frame 11 fixedly connected to the inner side of the dust collector 1. Multiple rotating shafts 12 are rotatably connected to the side wall of the fixed frame 11. The multiple rotating shafts 12 are grouped in pairs. A rotating plate 13 is fixedly connected to the outer side of each group of rotating shafts 12. The two rotating shafts 12 are connected by a gear assembly. The gear assembly includes two rotating shafts rotatably connected to the side wall of the dust collector 1. A spur gear 25 is fixedly sleeved on the outer side of each of the two rotating shafts and the two rotating shafts 12. Adjacent spur gears 25 mesh with each other. The number of teeth of the four spur gears 25 is exactly the same. The two outermost spur gears 25 in the gear assembly are connected to the rotating shaft 1. 2. Fixed connection: A spur gear 14 and a spur gear 25 are rotatably mounted on the side wall of the dust collector 1. Both spur gears 14 and 25 mesh with a gear assembly. Spur gear 14 meshes with the leftmost spur gear 35 in the gear assembly, and spur gear 25 meshes with the rightmost spur gear 35 in the gear assembly. Spur gears 14 and 25 are not on the same plane. Two drive shafts are rotatably connected to the side wall of the dust collector 1. A drive motor 16 is fixedly mounted on one end of one drive shaft. Circular plates 17 are fixedly sleeved on the outer sides of both drive shafts. Belts 18 are rotatably sleeved on the outer sides of the two circular plates 17. A spur rack 19 and a spur gear 10 are fixedly connected to the side wall of the belt 18. As rack 20 and spur rack 19 move with belt 18, they mesh with spur gear 14, causing spur gear 14 to rotate clockwise. This, in turn, causes the two rotating plates 13 to rotate upwards via the gear assembly, thus completing the closing state. Spur rack 20 meshes with spur gear 25, causing spur gear 25 to rotate clockwise. This, in turn, causes the two rotating plates 13 to rotate downwards via the gear assembly, changing the state from closed to open. The number of teeth on both rack 19 and rack 20 is sufficient to rotate the rotating plate 13 by 90 degrees. Furthermore, when rack 19 is not meshing with the last spur gear 14 during its movement, the spur gear... Only when rack 20 can it begin to mesh with the first spur gear 15, and vice versa. Both rack 19 and rack 20 have a certain degree of flexibility. A slide rail 26 is fixedly connected to the side wall of the dust collector 1. A slide groove is opened on the inner side of the slide rail 26. Both rack 19 and rack 20 are slidably connected to the slide groove. By sliding in the slide groove, the support of rack 19 and rack 20 is ensured, and the situation of sagging and failure to mesh is avoided. The rotating connection of the aforementioned spur gear 14, spur gear 25 and spur gear 3 all have rubber gaskets with a high coefficient of friction, which prevents rotation under normal conditions and has a certain self-locking ability.
[0014] A vibration structure is installed on the fixed frame 11. The vibration structure includes multiple sliders 21 slidably connected to the side wall of the fixed frame 11. The upper side of the sliders 21 has an inclined sliding surface. Each slider 21 is fixedly connected to the fixed frame 11 with a spring 22. Vibration blocks 23 are fixedly connected to the lower side of the sliders 21. Multiple pressing blocks 24 are fixedly connected to the side wall of the rotating plate 13. Each pressing block 24 corresponds to one slider 21. During the movement of the rotating plate 13 and the pressing blocks 24, the sliders 21 can be pressed. After the pressing is released, the sliders 21 are reset by the elastic force of the spring 22, thereby vibrating the rotating plate 13 by the vibration blocks 23.
[0015] In this invention, dust from the dry powder production line is first drawn in through the suction port and then enters the dust collector 1 through the air inlet pipe 3. The dust is filtered by the filter bags 5 inside the dust collector 1, causing the dust to adhere to the surface of the filter bags 5. After a certain period, the filter bags 5 are blown by the pulse jet system 9, causing them to shake and dislodge the dust. At this time, the drive motor 16 drives one of the circular plates 17 to rotate via the drive shaft, which in turn causes the belt 18 to rotate. The rotation of the belt 18 causes the first spur rack 19 and the second spur rack 20 to move along with the belt 18. During the movement, the first spur rack 19 meshes with the first spur gear 14, thereby driving the rotating plate 13 to rotate upwards through the gear assembly, thus completing the closing process. After the first spur rack 19 has finished meshing with the last spur gear 14, the second spur rack 20 begins to mesh with the first spur gear. The gear 15 engages, causing the rotating plate 13 to rotate downwards via the gear assembly, and then open sequentially. The closed rotating plate 13 can block the entry of dust-laden gas, thus avoiding the situation where dust is suspended due to collision with the shaken-off dust. After the rotating plate 13 is opened, dust-laden gas can re-enter. At this time, the shaken-off dust has completely settled on the rotating plate 13, and the entry of dust-laden gas will no longer cause dust to be suspended. The rotation of the belt 18 causes the rotating plate 13 to switch between the open and closed states, thereby improving the dust filtration efficiency. When the rotating plate 13 rotates downwards, the squeezing block 24 on the side wall can squeeze the corresponding slider 21. After the squeezing stops, the slider 21 can be ejected by the elastic force of the spring 22, thereby causing the vibrating block 23 to vibrate the rotating plate 13, so that the dust on the surface of the rotating plate 13 can fall off better, avoiding the situation where too much dust remains.
