Description

Technical Field

[0001] This utility model relates to the technical field of multi-stage baffle dust suppression devices, and in particular to a multi-stage baffle dust suppression device. Background Technology

[0002] The baffle is used to guide the polluted gas, so that the gas can be blown towards the central area of ​​the water spray from multiple spray dust suppression heads to achieve a better dust suppression effect.

[0003] In order to further improve the dust reduction effect, multi-stage baffles are often used for dust removal. However, when the gas carrying dust and water vapor passes through the subsequent baffles, it is easy to stick to the baffles, which will solidify on the baffles and affect the baffles' guiding effect on the subsequent gas. Utility Model Content

[0004] Therefore, it is necessary to provide a multi-stage baffle dust suppression device to address the technical problem of impurities easily adhering to the baffle plates mentioned above.

[0005] To achieve the above objectives, this utility model provides a multi-stage baffle dust suppression device, including a frame and a pipe. Several baffles are installed inside the pipe, and several rotating rings are rotatably and sealed on the pipe. The rotating rings are spaced apart from the baffles, and several scrapers are installed inside the rotating rings. A ring rack is installed on the rotating rings. A threaded rod is rotatably installed on the frame, and a gear is threadedly connected to the threaded rod. A fixing plate is installed on the pipe, and the gear, ring rack, and fixing plate are configured to cooperate. A limit plate is installed on the pipe, and an abutment plate is installed on the ring rack.

[0006] Preferably, a rotary drive device is mounted on the frame, and the output end of the rotary drive device is connected to the threaded rod drive.

[0007] Preferably, a plurality of rollers are rotatably mounted on the fixed plate.

[0008] Preferably, a storage box is installed at the bottom of the pipe using bolt fasteners.

[0009] Preferably, the scraper has a groove in the middle, and a brush is installed in the groove.

[0010] Preferably, the limiting plate is located on the upper and lower sides of the fixing plate, the limiting plate is made of magnetic material, and the abutment plate is made of magnet.

[0011] Compared with existing technologies, this technical solution has at least one of the following beneficial effects:

[0012] 1. Through the meshing transmission of gears and ring racks, the rotating ring can drive several scrapers inside to scrape off the solidified impurities on the surface of the baffle plate, thereby improving the baffle plate's deflection effect.

[0013] 2. By setting up a fixed plate, a limiting plate, and an abutment plate, the gear can drive one ring rack after it has finished driving one ring rack, and then be driven forward by the threaded rod to drive the next ring rack. Thus, a single drive source is used to drive and clean multiple baffles, reducing production costs. Attached Figure Description

Detailed Implementation

[0018] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0019] Please see Figures 1 to 3 This application provides a multi-stage baffle dust suppression device, including a frame 1 and a pipe 2. The two ends of the pipe 2 can extend to a gas collection device and an exhaust pipe. A plurality of baffles 3 are fixedly installed inside the pipe 2. A plurality of rotating rings 4 are rotatably sealed on the pipe 2. The pipe 2 and the rotating rings 4 can be mutually inserted by setting an annular concave groove and an annular convex block, and cooperate with a sealing bearing to achieve a rotatable sealing connection. The rotating rings 4 and the baffles 3 are spaced apart. A plurality of scrapers 5 are fixedly installed inside the rotating rings 4. An annular rack 6 is fixedly installed on the rotating rings 4. A threaded rod 7 is rotatably installed on the frame 1. A gear 8 is threadedly connected to the threaded rod 7. A fixing plate 9 is fixedly installed on the pipe 2. The gear 8 is configured to cooperate with the annular rack 6 and the fixing plate 9. A limit plate 10 is fixedly installed on the pipe 2. An abutment plate 11 is fixedly installed on the annular rack 6.

[0020] In this embodiment, polluted gas is input from one end of pipe 2, and after being deflected by baffle 3 and dusted by several spray heads on pipe 2, it is discharged from the other end of pipe 2. When cleaning baffle 3, the threaded rod 7 drives gear 8 to move. At this time, since the upper teeth of gear 8 abut against fixed plate 9, gear 8 can move forward. When gear 8 moves to the annular rack 6, since the rotating ring 4 is rotatably mounted on pipe 2, gear 8 can drive the rotating ring 4 to rotate through the annular rack 6. Thus, several scrapers 5 inside the rotating ring 4 can scrape and clean the surface of baffle 3. After the annular rack 6 rotates a suitable distance, its abutting plate 11 abuts against the limiting plate 10 on pipe 2. At this time, the annular rack 6... Since rack 6 is essentially fixed, the gear 8 that abuts against it can be driven forward by threaded rod 7 until it abuts against fixed plate 9, and then move to the next ring rack 6 to drive it to rotate. Thus, a single drive source can drive the cleaning work of several baffles 3. When gear 8 is driven to the end, it can be reversed by threaded rod 7 to drive it back and repeat the cleaning work. The smoothness of rotation of rotating ring 4 can be improved by reducing the weight of rotating ring 4 and timely injecting lubricating oil to lubricate the sealing bearing between rotating ring 4 and pipe 2, thereby preventing gear 8 from being driven forward when meshing with ring rack 6. The width of ring rack 6 can also be widened to cope with the short forward movement distance when gear 8 meshes.

[0021] In some embodiments, to facilitate driving the threaded rod 7, a rotary drive device 12 is fixedly mounted on the frame 1. The rotary drive device 12 can be a servo motor, and can be specially designed as a servo motor with a low speed. The output end of the rotary drive device 12 is connected to the threaded rod 7 for transmission.

[0022] In some embodiments, in order to reduce the frictional force when the gear 8 abuts against the fixed plate 9, a plurality of rollers 13 are rotatably mounted on the fixed plate 9.

[0023] In some embodiments, to facilitate the collection and processing of impurities scraped off by the scraper 5, a collection box 14 is installed at the bottom of the pipe 2 by bolt fasteners. A sealing gasket should be installed between the collection box 14 and the pipe 2 to improve the sealing performance. The scraped impurities have a certain gravity, so a portion of them can fall into the collection box 14. The collection box 14 can be removed periodically for storage.

[0024] In some embodiments, to facilitate the cleaning of impurities within the holes of the baffle 5, a groove 15 is provided in the middle of the scraper 5, and a brush 16 is fixedly installed within the groove 15. The brush 16 is preferably made of a material with good elasticity, so that it can pop out and squeeze the impurities as it passes through the holes, causing them to fall off.

[0025] In some embodiments, to ensure that the rotating ring 4 will not rotate after the limiting plate 10 abuts against the fixing plate 9, the limiting plate 10 is positioned on the upper and lower sides of the fixing plate 9, so as not to affect the operation of the gear 8. The limiting plate 10 is made of magnetic material, the abutting plate 11 is made of magnet, and the other materials are preferably made of non-magnetic materials. This allows the limiting plate 10 and the abutting plate 11 to adhere to each other after abutting, preventing rotation due to internal airflow. Furthermore, by increasing the volume of both, the bearing capacity after abutting is improved, making it less likely for them to break when the gear 8 moves forward. Two limiting plates 10 are provided to avoid affecting the operation of the gear 8, and regardless of which limiting plate 10 the abutting plate 11 abuts against, the gear 8 can move to continue abutting against the fixing plate 9.

[0026] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
