Description
Technical Field
[0001] The utility model belongs to the technical field of dust removal of expansion agents, in particular to a dust removal device for expansion agent production. Background Art
[0002] Expansive agents are a crucial material used in construction projects. They can moderately expand concrete or mortar, compensating for shrinkage and effectively preventing cracking. Expansive agents work by generating expansive products during hydration, creating pre-compressive stress in the concrete during the hardening phase, thereby improving its crack resistance and impermeability. Different types of expansive agents are suitable for different project requirements and environmental conditions, providing a strong guarantee for building quality and safety. Expansive agent production is often used in dust removal devices.
[0003] The dust removal device for expansion agent production usually consists of a dust suction port, a pipe, a filter component, a fan and a dust collection box. The dust suction port is close to the dust-generating point of the expansion agent production equipment and is connected to the filter component through a pipe. The principle is that the dust-laden gas enters the pipe under the action of the fan. When passing through the filter component, larger dust particles are intercepted, while smaller dust adheres to the filter screen or the surface of the filter bag. As time goes by, the dust on the filter screen gradually increases. When the resistance reaches a certain value, the dust is removed by pulse blowing or vibration and falls into the dust collection box.
[0004] The existing dust removal device for expansion agent production mostly performs one-time filtration in the dust removal operation of the expansion agent. However, the general expansion agent may contain many kinds of dust, which may cause some large particles of dust to clog the filter structure and affect the subsequent dust removal operation; and the existing dust removal device for expansion agent production has insufficient cleaning effect on the filamentous impurities inside the expansion agent, which may cause the filamentous impurities to clog the device and make the subsequent dust removal operation impossible. Therefore, in response to the above problems, an expansion agent production dust removal device is proposed. Utility Model Content
[0005] In order to make up for the deficiencies of the prior art and address the problems existing in the existing equipment, the utility model proposes a dust removal device for expansion agent production.
[0006] The technical solution adopted by the present utility model to solve its technical problems is a dust removal device for expanding agent production, including a fuselage. At the top of the fuselage, there is a feeding table. Inside the feeding table, there is a feeding port, and the feeding port is connected to the inside of the fuselage. On both sides of the top of the feeding port, there are support rods. At the top of the two groups of support rods, there is a top plate. On the top of the top plate, three first motors are installed. The output end of the first motor is provided with a screw rod, and the bottom end of the screw rod is placed inside the feeding port. At the bottom of the feeding port, there is a first filter plate. At the bottom end of one side of the first filter plate, there is a first support plate. Inside the first support plate, there is a protective box. Inside the protective box, a second motor is installed. The output end of the second motor is linked to a rotating shaft, and in the center of the rotating shaft, there is a second support plate. In the center of the second support plate, there is a punching hammer. A circular hole is opened in the center of the first support plate. The punching hammer passes through the circular hole in the center of the first support plate and closely adheres to the bottom side of the first filter plate. Through the design of adding a stirring device at the feeding port, the flocculent dust of the expanding agent is processed by the stirring device to avoid the flocculent dust blocking the device.
[0007] Preferably, the bottom of the first support plate is welded and connected to a second filter plate. On the side of the second filter plate away from the first support plate, there is a baffle. On the side of the first filter plate away from the first support plate, it closely adheres to the first outlet. On the side of the second filter plate close to the first support plate, there are through holes. The through holes on one side of the first support plate closely adhere to the second outlet. Through the design of adding a baffle on one side of the filter plate, when the expanding agent passes through the baffle, the expanding agent can be blocked by the baffle to avoid the leakage of the expanding agent. And through the design of adding through holes on the other side of the filter plate, it can assist the dust filtered out by the expanding agent to be discharged from the device to avoid the reduction of dust removal efficiency caused by dust accumulation.
[0008] Preferably, the bottom end of the baffle is welded and connected to the first support plate. The bottom end of the first support plate is welded and connected to a third filter plate. The design of both sides of the third filter plate is the same as that of both sides of the second filter plate. The opening on one side of the third filter plate is connected to a converging port, and the bottom end of the converging port is connected to a third outlet. Outside the converging port, there is a base. At the bottom end of the base outside the converging port, there are three support seats. Through the design of adding a converging port at the bottom of the device, it can assist in discharging materials, and adding support seats at the bottom of the base increases the stability of the device operation.
[0009] The advantages of the present utility model are as follows:
[0010] Through the design of adding a baffle on one side of the filter plate, the expander can be blocked by the baffle when passing through the baffle, avoiding the leakage of the expander. And through the design of adding perforations on the other side of the filter plate, it can assist in discharging the dust filtered out by the expander from the device, avoiding the reduction of the dust removal efficiency caused by dust accumulation. The dust removal operation of the expander is carried out by filtering through three groups of filter plates and adding an oscillation device at the bottom of the filter plate, thereby avoiding the problem of insufficient dust removal due to insufficient filtering.

[0019] Please refer to Figures 1-5As shown in the figure, a dust removal device for the production of an expanding agent includes a fuselage 1. At the top of the fuselage 1, there is a feeding table 6. Inside the feeding table 6, there is a feeding port 11, and the feeding port 11 is connected to the inside of the fuselage 1. On both sides of the top of the feeding port 11, there are support rods 7. At the top of the two groups of support rods 7, there is a top plate 8. On the top of the top plate 8, three first motors 9 are installed. The output end of the first motor 9 is provided with a screw rod 10, and the bottom end of the screw rod 10 is placed inside the feeding port 11. At the bottom of the feeding port 11, there is a first filter plate 12. At the bottom side of one side of the first filter plate 12, there is a first support plate 13. Inside the first support plate 13, there is a protective box 17. Inside the protective box 17, a second motor 19 is installed. The output end of the second motor 19 is linked to a rotating shaft 20. At the center of the rotating shaft 20, there is a second support plate 21. At the center of the second support plate 21, there is a punching hammer 22. There is a circular hole dug at the center of the first support plate 13. The punching hammer 22 passes through the circular hole at the center of the first support plate 13 and closely adheres to the bottom side of the first filter plate 12. The bottom of the first support plate 13 is welded to connect a second filter plate 16. On the side of the second filter plate 16 away from the first support plate 13, there is a baffle 18. The side of the first filter plate 12 away from the first support plate 13 closely adheres to the first outlet 2 on one side of the fuselage 1. When cleaning the flocculent dust inside the expanding agent, at this time, the operator places the expanding agent inside the feeding table 6, and then starts the first motor 9 at the top of the device. At this time, the first motor 9 drives the screw rod 10 at its bottom. At this time, the expanding agent starts to fall along the feeding port 11 under the action of the oscillation device at its bottom end. During this process, it will pass through the screw rod 10. At this time, the rotating screw rod 10 will stir the expanding agent and wind the flocculent dust inside the expanding agent around the surface of the screw rod 10, thereby completing the cleaning operation of the flocculent dust.
[0020] A perforation is provided on the side of the second filter plate 16 close to the first support plate 13, and the perforation on one side of the first support plate 13 is in close contact with the second outlet 3; the bottom end of the baffle 18 is welded to the first support plate 13, the bottom end of the first support plate 13 is welded to the third filter plate 15, and the designs on both sides of the third filter plate 15 are the same as those on both sides of the second filter plate 16; an opening on one side of the third filter plate 15 communicates with the converging port 14, and the bottom end of the converging port 14 communicates with the third outlet 4; a base is provided outside the converging port 14, and three support seats 5 are provided at the bottom end of the base outside the converging port 14; when dust removal operation is carried out on the expander, at this time the expander will enter the fuselage 1 along the feed port 11. At this time, the operator starts the second motor 19. Under the drive of the second motor 19, the rotating shaft 20 starts to drive the second support plate 21 to rotate, and the rammer 22 at its center starts to perform lifting operations, and when the rammer 22 reaches the apex, it impacts the filter plate. At this time, the expander will fall onto the first filter plate 12. Under the action of oscillation, the expander will enter the second filter plate 16 through the gap at the center of the first filter plate 12. In fact, the larger impurities will remain on the top of the first filter plate 12 and be discharged from the device along the first outlet 2 through the inclined design and the effect of oscillation; at the same time, the expander will fall into the second filter plate 16 under the action of the baffle 18. Similarly, the expander with a smaller volume will fall into the lower third filter plate 15 through the gap at the center of the second filter plate 16, while the larger dust will be discharged from the second outlet 3 through the perforation on one side of the second filter plate 16 under the action of oscillation; finally, the filtered expander will enter the converging port 14 through the perforation on one side of the third filter plate 15 under the action of oscillation and be discharged from the device along the third outlet 4.
[0021] Working principle: When cleaning the flocculent dust inside the expander, the operator places the expander inside the feeding table 6 at this time, and then starts the first motor 9 at the top of the device. At this time, the first motor 9 drives the screw 10 at its bottom. At this time, the expander starts to fall along the feeding port 11 under the action of the oscillation device at its bottom end. During this period, it will pass through the screw 10. At this time, the rotating screw 10 will stir the expander and wind the flocculent dust inside the expander around the surface of the screw 10, thus completing the cleaning operation of the flocculent dust; When performing the dust removal operation on the expander, at this time, the expander will enter the fuselage 1 along the feeding port 11. At this time, the operator starts the second motor 19. Under the drive of the second motor 19, the rotating shaft 20 starts to drive the second support plate 21 to rotate, and the impact hammer 22 at its center starts to perform lifting operations. When the impact hammer 22 reaches the apex, it will impact the filter plate. At this time, the expander will fall onto the first filter plate 12. Under the action of oscillation, the expander will enter the second filter plate 16 through the gap at the center of the first filter plate 12. In fact, the larger impurities will remain on the top of the first filter plate 12 and be discharged from the device along the first outlet 2 through the inclined design and the effect of oscillation; At the same time, the expander will fall onto the second filter plate 16 under the action of the baffle 18. Similarly, the expander with a smaller volume will fall into the lower third filter plate 15 through the gap at the center of the second filter plate 16, while the larger dust will be discharged from the second outlet 3 along the perforation on one side of the second filter plate 16 under the action of oscillation; Finally, the filtered expander will enter the converging port 14 along the perforation on one side of the third filter plate 15 under the action of oscillation and be discharged from the device along the third outlet 4.
