Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment technology, and in particular to a non-powered dustproof guide trough for belt conveyors. Background Technology

[0002] A non-powered dustproof guide chute for belt conveyors is a device used to reduce dust generated during material conveying. This device is usually installed at the loading or transfer point of the belt conveyor. Its main function is to isolate the material from the external environment in a closed or semi-closed manner, thereby effectively controlling the spread of dust, improving the working environment, and reducing pollution to the surrounding air.

[0003] In the prior art (application number CN221970763U, patent name 202420216037.7 A non-powered dust removal and material guiding trough device), a suction pipe and a fan are installed. A third limiting pin is threadedly connected to the inner side of one side of the suction pipe, and a dustproof groove is threadedly connected to the outer side of the third limiting pin. A fan is fixedly connected to the inner side of the suction pipe, and a dust collection box is slidably connected to the bottom of the suction pipe. When using the material guiding trough to transport materials, the bottom plate is placed under the conveyor belt. In implementing this technical solution, the inventors discovered at least the following problems in the prior art:

[0004] Currently, most dust removal systems for belt conveyors use external power sources such as fans and motors to clean the filter devices or maintain a negative pressure environment. This design results in high energy consumption and requires additional power systems, increasing operating costs. Existing devices often neglect the cleaning of filter plates, which can easily lead to blockages in the airflow channels after long-term operation, affecting overall ventilation capacity. Furthermore, the cleaning of filter plates usually relies on manual periodic cleaning or timed electric vibration devices. Utility Model Content

The flow-limiting damping curtain is detachably connected to the feed box.

[0008] Preferably, a bearing plate is fixedly connected to the side wall of the F-shaped bracket, and a half roller is fixedly connected to the top of the bearing plate, with the half roller in contact with the inner side of the conveyor belt of the conveyor.

[0009] Preferably, the bottom of the guide box is bolted with a composite anti-overflow skirt, and the side wall of the guide box is fixedly connected with a side anti-overflow plate, the side wall of the side anti-overflow plate being in contact with the inner side of the conveyor belt of the conveyor.

[0012] Preferably, the striking mechanism further includes a support frame fixedly connected to the inner wall of the dust collector, a return spring fixedly connected to the top of the support frame, and a filter plate fixedly connected to the top of the return spring.

[0013] Preferably, the outer wall of the connecting rod is provided with a cleaning mechanism, the cleaning mechanism including a reciprocating threaded groove formed on the outer wall of the connecting rod, a reciprocating moving plate being threadedly connected to the inner wall of the reciprocating threaded groove, a slide rod being slidably provided on the top of the reciprocating moving plate, and the bottom end of the slide rod penetrating the top of the reciprocating moving plate and extending to the outside.

[0014] Preferably, the cleaning mechanism further includes a sliding plate fixedly connected to the top of the slide rod, with guide rails slidably connected to both ends of the sliding plate, the top of the guide rails fixedly connected to the bottom of the filter plate, and a scraper fixedly connected to the side wall of the sliding plate, the outer surface of the scraper being in contact with the bottom of the filter plate.

[0015] Preferably, a discharge dust curtain is fixedly connected to the end of the guide box away from the feed hopper.

[0016] The beneficial effects of this application are:

[0017] This belt conveyor uses a non-powered dustproof guide chute. During material unloading from the feed hopper, a large amount of dust is generated. As the material falls into the hopper, it creates an impact airflow. This internal airflow disperses along the conveyor belt's running direction. The dust-laden airflow is guided back into the guide box via a return guide pipe, forming a circulating dust suppression system and reducing external emissions. When the air pressure inside the guide box becomes too high, the dust-laden airflow enters the dust collector. The filter plates filter the dust, and the louvers in the dust collector release pressure. When the dust-laden airflow passes through the S-shaped damping curtain, the curtain extends the path of the dust-laden airflow, causing the dust to adhere to its surface and settle. The flow-limiting damping curtain restricts the flow of the dust-laden airflow. Excess dust-laden airflow can flow from one end of the pressure-relief turbulence filter box to the other. The pressure-relief turbulence filter box then further reduces the speed, pressure, and dust concentration of the dust-laden airflow.

[0018] This belt conveyor features a non-powered dustproof guide chute. When the material descends from the feed hopper and enters the arc-shaped limiting groove, the inertia and gravity of the material push the arc-shaped plate to move. The arc-shaped plate then drives the drive roller and drive shaft to rotate. The drive shaft drives the connecting rod to rotate via the transmission belt. The connecting rod drives the collision component to periodically strike the surface of the filter plate. During the collision process, the dust adsorbed on the filter plate can be loosened and detached, improving filtration permeability and extending the service life of the filter material.

[0019] This belt conveyor features a non-powered dustproof guide chute. When the connecting rod rotates, it drives the reciprocating moving plate to move back and forth through the reciprocating threaded groove. The reciprocating moving plate drives the sliding rod and the sliding plate to move back and forth, thereby causing the sliding plate to drive the scraper to stick to the bottom surface of the filter plate for reciprocating scraping operation. This removes the dust particles deposited at the bottom of the filter plate, prevents dust accumulation from causing airflow blockage, improves the overall dust removal efficiency, and ensures the long-term stable operation of the system.

[0030] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0031] Please refer to Figures 1 to 8This utility model embodiment provides a non-powered dustproof material guide chute for a belt conveyor, including a conveyor 101. An F-shaped bracket 102 is fixedly connected to the side wall of the conveyor 101, and a guide box 103 is fixedly connected to the side wall of the F-shaped bracket 102. The guide box 103 serves as the main structure of the material conveying channel, guiding the directional flow of materials and forming a sealed space in conjunction with other dustproof components. A discharge dustproof curtain 104 is fixedly connected to the end of the guide box 103 away from the feed hopper 301. The discharge dustproof curtain 104 is located at the end of the guide box 103, and its flexible material reduces material impact while preventing dust overflow. It also includes:

[0032] The top of the feed box 103 is connected to a feed hopper 301, and the side wall of the feed hopper 301 is connected to a return guide pipe 302. The bottom end of the return guide pipe 302 passes through the top of the feed box 103 and extends to the inside. The return guide pipe 302 guides the dust airflow generated by the material falling on the conveyor 101 back into the feed hopper 301, forming a circulating dust suppression system and reducing external emissions. The top of the feed box 103 is connected to a dust collector 303, which is used to collect and treat the dust generated during the feeding process. At the same time, the louvers of the dust collector 303 can depressurize the feed box 103. The top of the feed box 103 is detachably equipped with an S-shaped damping curtain 304. The S-shaped damping curtain 304 can extend the travel path of the dust airflow, allowing the dust to be adsorbed on the surface of the S-shaped damping curtain 304 and thus settle. The top of the guide box 103 is fixedly connected to the pressure relief turbulence filter box 305. Both ends of the pressure relief turbulence filter box 305 are connected to the guide box 103. The pressure relief turbulence filter box 305 can further reduce the speed, pressure and dust of the dust-laden airflow. The bottom of the pressure relief turbulence filter box 305 is provided with a flow-limiting damping curtain 306. The flow-limiting damping curtain 306 is detachably connected to the guide box 103. The flow-limiting damping curtain 306 limits the flow of the dust-laden airflow. Excess dust-laden airflow can flow from one end of the pressure relief turbulence filter box 305 to the other end.

[0033] The side wall of the F-shaped bracket 102 is fixedly connected to a bearing plate 201, and the top of the bearing plate 201 is fixedly connected to a half roller 202. The half roller 202 is set to contact the inner side of the conveyor belt of the conveyor 101. The half roller 202 is used to help support the edge of the conveyor belt, prevent deviation or sagging, and reduce the risk of material spillage.

[0034] The bottom of the feed box 103 is bolted with a composite anti-overflow skirt 204. The composite anti-overflow skirt 204 fits tightly against the surface of the conveyor belt, preventing dust and fine materials from leaking from the bottom. The side wall of the feed box 103 is fixedly connected with a side anti-overflow plate 205. The side wall of the side anti-overflow plate 205 is set to contact the inner side of the conveyor belt of the conveyor 101. The side anti-overflow plate 205 and the inner side of the conveyor belt form a lateral seal to prevent materials from overflowing on the side of the conveyor belt.

[0035] A drive shaft 31 is rotatably connected to the side wall of the feed hopper 301. A drive roller 32 is fixedly connected to the outer wall of the drive shaft 31. The drive roller 32 is located inside the feed hopper 301. An arc-shaped limiting groove 33 is provided on the outer wall of the drive roller 32. A fixing rod 34 is fixedly connected to the inner wall of the arc-shaped limiting groove 33. An arc-shaped plate 35 is rotatably connected to the outer wall of the fixing rod 34. This arrangement is so that when the material descends from the feed hopper 301, when the material enters the arc-shaped limiting groove 33, the inertia and gravity generated by the material will push the arc-shaped plate 35 to move. The arc-shaped plate 35 will then drive the drive roller 32 and the drive shaft 31 to rotate.

[0036] The outer wall of the drive shaft 31 is provided with a striking mechanism 4. The striking mechanism 4 includes a transmission belt 401 sleeved on the outer wall of the drive shaft 31. A connecting rod 402 is connected to the inner wall of the transmission belt 401. The connecting rod 402 passes through the side wall of the dust collector 303 and extends to the outside. A collision member 403 is fixedly connected to the outer wall of the connecting rod 402. The striking mechanism 4 also includes a support frame 404 fixedly connected to the inner wall of the dust collector 303. A return spring 405 is fixedly connected to the top of the support frame 404. A filter plate 406 is fixedly connected to the top of the return spring 405. This arrangement is so that the drive shaft 31 drives the connecting rod 402 to rotate through the transmission belt 401, and the connecting rod 402 drives the collision member 403 to periodically strike the surface of the filter plate 406.

[0037] The outer wall of the connecting rod 402 is provided with a cleaning mechanism 5. The cleaning mechanism 5 includes a reciprocating threaded groove 501 formed on the outer wall of the connecting rod 402. A reciprocating moving plate 502 is threadedly connected to the inner wall of the reciprocating threaded groove 501. A slide rod 503 is slidably disposed on the top of the reciprocating moving plate 502. The bottom end of the slide rod 503 passes through the top of the reciprocating moving plate 502 and extends to the outside. The cleaning mechanism 5 also includes a sliding plate 504 fixedly connected to the top end of the slide rod 503. Guide rails 505 are slidably connected to both ends of the sliding plate 504. The top of the guide rail 505 is fixedly connected to the bottom of the filter plate 406. A scraper 506 is fixedly connected to the side wall of the sliding plate 504. The outer surface of the scraper 506 is in contact with the bottom of the filter plate 406. This arrangement is such that when the connecting rod 402 rotates, it drives the reciprocating moving plate 502 to reciprocate through the reciprocating threaded groove 501. The reciprocating moving plate 502 drives the slide rod 503 and the sliding plate 504 to reciprocate, thereby causing the sliding plate 504 to drive the scraper 506 to adhere to the bottom surface of the filter plate 406 for reciprocating scraping operation.

[0038] In summary, the working principle of the belt conveyor dustproof guide chute of this utility model embodiment is as follows: During use, a large amount of dust is generated during the unloading process of the material through the feed hopper 301. When the material falls into the feed hopper 301, it generates an impact airflow. The internal airflow disperses in all directions along the running direction of the conveyor belt. The dust-laden airflow is guided back into the guide box 103 through the return guide pipe 302, forming a circulating dust suppression and reducing external emissions. When the air pressure inside the guide box 103 is too high, the dust-laden airflow then enters the dust collection box 303, where the filter plate 406... Dust is filtered, and the louvers of the dust collector 303 depressurize the airflow. When the dust-laden airflow passes through the S-shaped damping curtain 304, the S-shaped damping curtain 304 extends the path of the dust-laden airflow, causing the dust to be adsorbed on the surface of the S-shaped damping curtain 304 and thus settle. The flow-limiting damping curtain 306 limits the flow of the dust-laden airflow. Excess dust-laden airflow can flow from one end of the pressure relief and turbulence filter box 305 to the other end. Subsequently, the pressure relief and turbulence filter box 305 can again reduce the speed, pressure and dust of the dust-laden airflow. The material after dust settling is discharged from the discharge dust curtain 104.

[0039] When the material descends from the feed hopper 301, its inertia and gravity push the arc plate 35 to move when it enters the arc-shaped limiting groove 33. The arc plate 35 then drives the drive roller 32 and drive shaft 31 to rotate. The drive shaft 31 drives the connecting rod 402 to rotate via the transmission belt 401. The connecting rod 402 drives the collision component 403 to periodically strike the surface of the filter plate 406. During the collision process, the dust adsorbed on the filter plate 406 can be loosened and detached, improving filtration permeability and extending the service life of the filter material. When the connecting rod 402 rotates, it drives the reciprocating moving plate 502 to reciprocate through the reciprocating threaded groove 501. The reciprocating moving plate 502 drives the sliding rod 503 and sliding plate 504 to reciprocate, thereby causing the sliding plate 504 to drive the scraper 506 to reciprocate and scrape against the bottom surface of the filter plate 406 to remove dust particles deposited at the bottom of the filter plate 406, preventing dust accumulation from causing airflow blockage, improving overall dust removal efficiency, and ensuring long-term stable operation of the system.

[0040] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
