Description

Technical Field

[0001] This utility model relates to the field of environmental protection and energy-saving equipment, and in particular to the regulating damper of a dust collector. Background Technology

[0002] With the acceleration of industrialization, various industrial production activities are becoming increasingly frequent, such as mining, metallurgy, power generation, cement, chemical processing, and grain cleaning. These industries generate large amounts of dust during production. If this dust is released directly into the atmosphere without effective treatment, it will not only cause serious environmental pollution, affecting air quality and ecological balance, but also endanger workers' health, causing occupational diseases such as pneumoconiosis. To reduce dust pollution and protect workers' health and the environment, dust collectors are being used more and more widely.

[0003] During production, operating conditions may change, such as variations in flue gas volume and dust concentration. Dust collectors may struggle to adapt to these changes, leading to a significant drop in dust collection efficiency during periods of fluctuating operating conditions. Unstable and uneven airflow can cause additional impact and wear on various components of the dust collector, making it difficult to maintain stable dust collection performance, shortening equipment lifespan, increasing maintenance costs and the frequency of component replacement, and necessitating regular cleaning. During dust collector operation, dust flows with the airflow, and some dust may adhere to parts such as the blades of regulating dampers. Over time, this dust accumulation gradually blocks the damper passages, reducing the effective ventilation area of ​​the dampers, affecting normal airflow, and ultimately reducing the overall performance of the dust collector. Utility Model Content

[0004] The main purpose of this utility model is to provide a dust collector regulating damper, which can effectively solve the problems that cause the dust collector to have difficulty maintaining stable dust removal performance, shorten the service life of the equipment, increase maintenance costs and the frequency of replacing parts, require regular cleaning, and reduce the effective ventilation area of ​​the damper, affecting the normal passage of airflow, and thus reducing the overall performance of the dust collector.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dust collector regulating damper, including a flow guide box, wherein an regulating mechanism is provided inside the front side wall of the flow guide box;

[0006] The adjustment mechanism includes: an outer frame, two fixed brackets, and a first support rod. The outer side of the outer frame is located inside the front side wall of the flow guide box. An outer support plate is fixedly connected to the outer side of the front side wall of the outer frame. The rear side wall of the outer support plate is threadedly connected to the inner wall of the flow guide box. The two fixed brackets are fixedly connected to the left and right sides of the outer frame. Three sleeves are fixedly connected inside each fixed bracket. The other ends of the six sleeves are connected through to the left and right side walls of the outer frame. A first rotating rod is rotatably connected inside the middle sleeve. A first connecting cylinder is threadedly connected to the outer side of the middle part of the first rotating rod. A first fixing ring is fixedly connected to both the left and right ends of the first connecting cylinder. A first blade is fixedly connected to both the upper and lower sides of the first fixing ring.

[0007] Furthermore, a first support rod is fixedly connected to the outer left end of the first rotating rod, a connecting column is rotatably connected to the inner front side of the first support rod, a handle is fixedly connected to the front side of the first support rod, and a second rotating rod is rotatably connected to the inner sides of the upper and lower sleeves. A second connecting cylinder is threadedly connected to the outer middle part of each pair of second rotating rods.

[0008] Furthermore, each of the second connecting cylinders is fixedly connected to the left and right ends with a second fixing ring, and each of the second connecting cylinders is fixedly connected to the upper and lower sides with a second blade. The outer left end of each of the two second rotating rods is fixedly connected to a second support rod, and the front side of each of the second support rods is rotatably connected to a connecting rod. The other end of each of the two connecting rods is rotatably connected to the outer left end of the connecting column.

[0009] Furthermore, a control panel is fixedly connected to the right side wall of the flow guide box, and protective boxes are fixedly connected to both the upper and lower sides of the right side wall of the flow guide box. A motor is installed inside each of the two protective boxes, and guide rails are fixedly connected to both the upper and lower sides of the inner front side wall of the flow guide box. The two guide rails are arranged on the upper and lower sides of the outer support plate.

[0010] Furthermore, the output ends of the two motors are fixedly connected to rotating shafts, and pulleys are fixedly connected to the outer top of the two rotating shafts. Belts are installed inside the two pulleys, and the left sides of the two belts are installed inside two guide rails. Slider blocks are installed on the front sidewalls of the two guide rails, and four pulleys are fixedly connected to the rear sidewall of each slider.

[0011] Furthermore, each set of four pulleys is slidably connected to the upper and lower slots of a guide rail, and each slider has a fixing block inside. Each fixing block is threaded to fix a portion of the front side of the belt inside the slider, and a connecting plate is fixedly connected to the front sidewall of each of the two sliders.

[0012] Furthermore, a support plate is fixedly connected to the front sidewall of the two connecting plates, and a brush is fixedly connected to the rear sidewall of the support plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model, through its adjustable mechanism, solves the problems that cause dust collectors to struggle to maintain stable dust removal performance, shorten equipment lifespan, increase maintenance costs and the frequency of component replacement, and require regular cleaning. When the second rotating rod rotates, the second connecting cylinder moves axially along the rod. The second connecting cylinder is fixedly connected to second fixing rings at its left and right ends, and to second blades at its upper and lower sides. Therefore, the movement of the second connecting cylinder drives the movement of the second blades. This movement of the second blades further alters the airflow channel and distribution within the guide box, working in conjunction with the first blade to more precisely regulate the airflow within the guide box. This effectively improves overall dust removal efficiency, extends equipment lifespan, reduces maintenance costs and downtime, and enhances the stability and reliability of the entire device.

[0015] 2. By incorporating a motor, guide rail, pulleys, belt, sheaves, support plate, and brushes, the system effectively addresses the problem of reduced ventilation area at the damper, hindering normal airflow and consequently lowering the overall performance of the dust collector. A fixed block, threaded with screws, secures a portion of the front side of the belt inside the slider, ensuring synchronized movement between the slider and belt. As the slider moves, the connecting plate fixedly connected to its front side wall also moves accordingly. The support plate, fixedly connected to the front side walls of the two connecting plates, moves up and down along the guide rail along with the slider. The brushes fixedly connected to the rear side wall of the support plate also move synchronously, effectively improving dust removal efficiency at each stage, reducing downtime for maintenance, and enhancing system operating efficiency and production continuity.

[0031] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0032] like Figure 1 - Figure 6As shown: The dust collector regulating damper includes a flow guide box 1, and an regulating mechanism 2 is provided inside the front side wall of the flow guide box 1;

[0033] The adjustment mechanism 2 includes an outer frame 201, two fixing brackets 203, and a first support rod 209. The outer side of the outer frame 201 is located inside the front side wall of the guide box 1. An outer support plate 202 is fixedly connected to the outer side of the front side wall of the outer frame 201. The rear side wall of the outer support plate 202 is threadedly connected to the inner wall of the guide box 1. The outer frame 201 is fixed inside the guide box 1 by the outer support plate 202 on the outer side of the front side of the outer frame 201. The two fixing brackets 203 are fixedly connected to the left and right sides of the outer frame 201. Three sleeves 204 are fixedly connected inside each fixing bracket 203. The other ends of the six sleeves 204 are connected through the left and right side walls of the outer frame 201. The fixing brackets 203 on the left and right sides of the outer frame 201 support and fix the sleeves 204 inside, thereby providing a stable rotation effect for the internal components.

[0034] A first rotating rod 205 is rotatably connected inside a sleeve 204 in the middle. A first connecting sleeve 206 is threadedly connected to the outer side of the middle of the first rotating rod 205. First fixing rings 207 are fixedly connected to both ends of the first connecting sleeve 206. First blades 208 are fixedly connected to the upper and lower sides of the first fixing rings 207. The sleeve 204 supports the left and right sides of the first rotating rod 205, providing a stable and balanced effect. The outer side of the first rotating rod 205 is connected to the first connecting sleeve 206 by bolts. When the first rotating rod 205 rotates, the first connecting sleeve 206... A rotating rod 205 drives the first connecting cylinder 206 to rotate inside the outer frame 201, and is fixed to the left and right ends of the first connecting cylinder 206 by the first fixing ring 207 to support the first connecting cylinder 206. The first connecting cylinder 206 and the first fixing ring 207 are connected to the external first blade 208. When the first rotating rod 205 is driven, it drives the first blade 208 to rotate, and the rotation of the first blade 208 opens the interior of the outer frame 201 to block or guide the airflow in the guide box 1, and initially adjust the airflow.

[0035] like Figure 1 - Figure 6As shown, a first support rod 209 is fixedly connected to the outer left end of the first rotating rod 205. A connecting column 210 is rotatably connected to the inner front side of the first support rod 209. A handle 215 is fixedly connected to the front side of the first support rod 209. When the operator pulls the handle 215, the first support rod 209 connected to the handle 215 will also rotate synchronously. The handle 215 is fixedly connected to the outer left end of the first rotating rod 205 through the rear side of the first support rod 209. Thus, by pulling the handle 215, the first connecting cylinder 206 and the first blade 208 inside the outer frame 201 can be rotated to open and close the flow port of the outer frame 201.

[0036] The inner sides of the upper and lower sleeves 204 are rotatably connected to second rotating rods 211. A second connecting sleeve 212 is threadedly connected to the outer side of the middle portion of each pair of second rotating rods 211. Second fixing rings 213 are fixedly connected to both ends of each second connecting sleeve 212. Second blades 214 are fixedly connected to the upper and lower sides of each second connecting sleeve 212. A second support rod 217 is fixedly connected to the outer side of the left end of each of the two second rotating rods 211. A connecting rod 216 is rotatably connected to the front side of each second support rod 217. The other ends of the two connecting rods 216 are rotatably connected to a connecting post 21. On the outer left side of the 0, a connecting rod 216 on the connecting column 210 connects to the second support rods 217 on the upper and lower sides. When the handle 215 is pulled, the two second support rods 217 rotate simultaneously, causing the second rotating rod 211 inside the rear side of the two second support rods 217 to rotate within the upper and lower sleeves 204. When the second rotating rod 211 rotates, the second connecting cylinder 212 moves along the axial direction of the second rotating rod 211, and the movement of the second connecting cylinder 212 causes the second fixing ring 213 and the second blade 214 to rotate inside the outer frame 201. The rotation of the second blade 214 further changes the airflow channel and airflow distribution within the guide box 1, working in conjunction with the first blade 208 to more precisely regulate the airflow within the guide box 1.

[0037] Additionally, when adjusting mechanism 2 is closed, such as Figure 4 As shown, baffles are fixed on both the upper and lower sides of the inner side of the outer frame 201. When the operator pulls the handle 215 upward, it connects to the two second support rods 217 through the connecting rod 216 on the connecting column 210. This simultaneously drives the first blade 208 and the two second blades 214 to rotate. When the rotation reaches a certain extent, the rear sides of the upper and lower second blades 214 will contact the baffles inside the outer frame 201 to prevent the second blades 214 from rotating excessively when the adjustment mechanism 2 is closed, thus preventing the first blade 208 and the second blades 214 from sticking together and failing to achieve the closing effect.

[0038] like Figure 1 - Figure 11As shown, a control panel 3 is fixedly connected to the right side wall of the flow guide box 1, and the entire device is controlled through the control panel 3. Protective boxes 4 are fixedly connected to both the upper and lower sides of the right side wall of the flow guide box 1. Motors 5 are installed inside both protective boxes 4. The protective boxes 4 on the upper and lower sides of the right side wall of the flow guide box 1 provide external protection and support for the two motors 5.

[0039] The upper and lower sides of the inner front wall of the flow guide box 1 are fixedly connected to guide rails 6. The two guide rails 6 are set on the upper and lower sides of the outer support plate 202. The output ends of the two motors 5 are fixedly connected to rotating shafts 7. The outer sides of the top of the two rotating shafts 7 are fixedly connected to pulleys 8. The two pulleys 8 are equipped with belts 9. The left side of the two belts 9 is set inside the two guide rails 6. The control panel 3 sends a start command to the motors 5. When the motors 5 start, the rotating shafts 7 on the output end of the motors 5 will rotate on the pulleys 8 at their top. When the pulleys 8 rotate, they generate friction with the belts 9 inside, which drives the belts 9 to rotate. When the belts 9 rotate, the other side of the belts 9 will rotate inside the guide rails 6.

[0040] Both guide rails 6 are equipped with sliders 10 on their front sidewalls. Each slider 10 is fixedly connected to four pulleys 11 on its rear sidewall. Each set of four pulleys 11 is slidably connected in the slots on the upper and lower sides of a guide rail 6. When the slider 10 is driven, the pulleys 11 on the rear side of the slider 10 will slide in the slots on the upper and lower sides of the guide rail 6 to support the slider 10 and provide a stable sliding effect.

[0041] like Figure 1 - Figure 12 As shown, each slider 10 has a fixing block 12 inside. Each fixing block 12 fixes a portion of the front side of the belt 9 to the inside of the slider 10 by means of threads. The front side of the belt 9 and the fixing block 12 are fixed in the inside of the slider 10 by means of threads, so that when the motor 5 rotates in both directions, it drives the belt 9 and the slider 10 to slide left and right on the front side wall of the guide rail 6.

[0042] Both sliders 10 have connecting plates 13 fixedly connected to their front sidewalls. Support plates 14 are fixedly connected to the front sidewalls of the two connecting plates 13. A brush 15 is fixedly connected to the rear sidewall of the support plate 14. The connecting plates 13 on the front sidewalls of the two sliders 10 connect to the support plate 14, and the support plate 14 connects to the brush 15 at the bottom, causing the support plate 14 and brush 15 to slide left and right. The brush 15 is located on the front sidewall of the outer frame 201, corresponding to the first blade 208 and the two second blades 214. When started, the motor 5 drives the brush 15 to slide left and right on the front sidewalls of the outer frame 201 and the first and second blades 208 and 214, cleaning the front sidewalls of the first and second blades 208 and removing dust adhering to them.

[0043] It should be noted that this utility model is a dust collector regulating damper. First, the control panel 3 and the motor 5 are connected to an external power source to supply power to the device.

[0044] When the operator turns handle 215, the first support rod 209 connected to handle 215 will rotate accordingly. Since the first support rod 209 is fixedly connected to the outer left end of the first rotating rod 205, the first rotating rod 205 will rotate within the sleeve 204 in the middle. The direction of rotation of the first rotating rod 205 is determined by the direction of rotation of handle 215.

[0045] The first rotating rod 205 is threadedly connected to the first connecting cylinder 206 on its outer side. When the first rotating rod 205 rotates, according to the principle of threaded transmission, the first connecting cylinder 206 will move along the axial direction of the first rotating rod 205. The left and right ends of the first connecting cylinder 206 are fixedly connected to the first fixing ring 207, and the upper and lower sides of the first fixing ring 207 are fixedly connected to the first blade 208. Therefore, the movement of the first connecting cylinder 206 will drive the first blade 208 to move. The movement of the first blade 208 will change its position in the guide box 1, thereby blocking or guiding the airflow in the guide box 1 and initially regulating the airflow.

[0046] When the first support rod 209 rotates, the connecting column 210, which is rotatably connected to its front side, also moves. The rotation of the first support rod 209 drives the second support rod 217 to rotate through the connecting column 210 and the connecting rod 216, thereby causing the second rotating rod 211 to rotate within the upper and lower sleeves 204. The second rotating rod 211 is threadedly connected to the second connecting cylinder 212 on the outer side of its middle section. When the second rotating rod 211 rotates, the second connecting cylinder 212 moves along the axial direction of the second rotating rod 211. The second connecting cylinder 212 is fixedly connected to the second fixing ring 213 at both ends and to the second blade 214 on both the upper and lower sides. Therefore, the movement of the second connecting cylinder 212 will drive the movement of the second blade 214. The movement of the second blade 214 further changes the airflow channel and airflow distribution within the guide box 1, working in conjunction with the first blade 208 to more precisely regulate the airflow within the guide box 1.

[0047] Operators can flexibly adjust the positions of the first blade 208 and the second blade 214 by rotating the handle 215 according to actual needs, thereby changing the size and shape of the airflow channel in the guide box 1 and adjusting the airflow volume and distribution of the dust collector. When it is necessary to increase the airflow, the handle 215 can be rotated to open the blades at a larger angle and expand the airflow channel; when it is necessary to decrease the airflow, the handle 215 can be rotated to close the blades at a fixed angle and narrow the airflow channel.

[0048] After the motor 5 starts, the rotating shaft 7 at its output end begins to rotate, driving the pulley 8 on the outer side of the top to rotate. The rotation of the pulley 8 causes the mating belt 9 to move. Since the left side of the belt 9 is located inside the guide rail 6, the belt 9 rotates in a cycle under the constraint of the guide rail 6. When the belt 9 moves, the slider 10 on its front side wall moves along with the belt 9. The four pulleys 11 on the rear side wall of the slider 10 slide in the slots on the upper and lower sides of the guide rail 6, providing support and guidance to ensure that the slider 10 can move smoothly along the guide rail 6. The fixing block 12 fixes a part of the front side of the belt 9 inside the slider 10 by threads, ensuring the synchronous movement of the slider 10 and the belt 9. When the slider 10 moves, the connecting plate 13 fixedly connected to its front side wall also moves accordingly. The front side walls of the two connecting plates 13 are fixedly connected to the support plate 14, so the support plate 14 moves up and down along the guide rail 6 along with the slider 10. The brush 15 fixedly connected to the rear side wall of the support plate 14 also moves synchronously.

[0049] Since the brush 15 is correspondingly arranged with the first blade 208 and the two second blades 214, when the brush 15 moves left and right, it cleans the surfaces of the first blade 208 and the second blades 214, removing dust adhering to the blades. This prevents dust accumulation from affecting the normal adjustment function of the blades, ensures the adjustment accuracy and efficiency of the adjustment mechanism, and extends the service life of the adjustment mechanism.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
