Abstract
Description
Technical Field
[0001] This utility model belongs to the field of conveying equipment, and specifically relates to a dust sealing structure for a coal conveyor belt. Background Technology
[0002] Coal conveyor belts are widely used in coal mines, power plants, ports, and other locations for transporting coal. During operation, mechanical vibrations and material drop impacts during loading, unloading, and conveying generate significant amounts of dust. On one hand, this dust can enter the conveyor belt's drive components, accelerating wear on rollers and idler bearings, increasing equipment failure frequency, and shortening service life. On the other hand, the dispersed dust pollutes the surrounding environment, and some dust settles and accumulates on the conveyor belt surface, potentially causing belt misalignment and affecting conveying efficiency and stability. Conventional methods include water spraying to suppress dust, but excessive moisture increases the coal's moisture content, affecting coal quality and combustion performance, and can also cause the conveyor belt to slip due to dampness. Cleaning devices are also used to promptly remove spilled dust; however, the cleaning process easily disturbs settled dust and cannot control dust generation at its source. Delayed cleaning can also cause secondary dust re-entrainment, making it difficult to fundamentally solve the dust pollution and equipment wear problems caused by the lack of a sealed structure. Therefore, a new structure is needed to address these technical issues. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a dust sealing structure for coal conveyor belts, and solve the problems mentioned in the background art.
[0004] This utility model is achieved through the following technical solution: a dust sealing structure for a coal conveyor belt, comprising: a conveying component, a sealing component, and a dust collection component. The upper surface of the conveying component is equipped with a sealing component for sealing dust, and the upper surface of the sealing component is equipped with a dust collection component for collecting coal dust. The conveying component includes a mounting frame for mounting the conveyor belt, the sealing component is composed of multiple sealing covers, and the dust collection component includes a dust collection pipe for collecting dust, with a dust collection head installed at the lower end of the dust collection pipe.
[0005] In a preferred embodiment, a plurality of support legs are evenly mounted on the lower surface of the mounting frame, and an output roller is rotatably mounted on the front and rear edges of the mounting frame. A drive motor is mounted on the right side surface of the front output roller, and a conveyor belt is rotatably mounted inside the mounting frame via two output rollers.
[0006] In a preferred embodiment, multiple sets of bearing seats are symmetrically installed on the lower side of the mounting frame, and a receiving roller is rotatably installed between two of the bearing seats. The outer surface of the receiving roller abuts against the lower surface of the conveyor belt, and a baffle is installed on the left and right edges of the upper surface of the mounting frame.
[0007] In a preferred embodiment, a feed cylinder is installed on the rear edge of the upper surface of the mounting frame. The upper surface of the feed cylinder is open, and the opening of the lower surface of the feed cylinder is aligned with the upper surface of the conveyor belt. A cover plate is hinged to the rear edge of the upper surface of the feed cylinder.
[0008] In a preferred embodiment, the lower surface of the cover plate abuts against the upper surface of the feed cylinder. Multiple sealing covers are mounted on the upper part of the conveyor belt via mounting brackets. The multiple sealing covers have the same structure and abut against each other. Sealing gaskets are provided at the abutment points between the sealing covers. In use, the multiple sealing covers can be arranged along the length and width of the conveyor belt to fully cover the upper surface of the conveyor belt, effectively preventing dust generated during coal transportation from flying outward, reducing the diffusion of dust in the working environment, and improving the sealing effect.
[0009] In a preferred embodiment, a handle is installed on the left and right surfaces of the sealing cover, a circular through hole is provided at the center of the upper surface of the sealing cover, the circular through holes are spaced apart, and the suction pipe has an L-shaped structure.
[0010] In a preferred embodiment, the end of the suction pipe furthest from the sealing cover is connected to a vacuuming device. A connecting flange is installed on the outer surface of the suction pipe, and the suction pipe is sealed to a circular through-hole through the connecting flange. The suction head at the lower end of the suction pipe is located inside the sealing cover. During use, the suction pipe and the suction head work together to continuously suck out the dust from the sealing assembly, creating a relative negative pressure in the sealed space. This helps to prevent dust from leaking out from the gaps in the sealing cover and, together with the sealing assembly, further improves the dust sealing effect.
[0011] After adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. By setting a sealing component, a sealing component for sealing dust is installed on the upper surface of the conveying component. The conveying component includes a mounting frame for installing the conveyor belt. The sealing component is composed of multiple sealing covers. In use, the multiple sealing covers can be arranged along the length and width of the conveyor belt, which can fully cover the upper surface of the conveyor belt, effectively blocking the dust generated during coal transportation from flying outward, reducing the diffusion of dust in the working environment, and improving the sealing effect.
[0012] 2. By setting up a dust collection component, a dust collection component for collecting coal dust is installed on the upper surface of the sealing component. The dust collection component includes a dust collection pipe for collecting dust, and a dust collection head is installed at the lower end of the dust collection pipe. During use, the dust collection pipe and the dust collection head work together to continuously suck out the dust inside the sealing component, so that a relative negative pressure is formed in the sealed space.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1 to 3This utility model provides a technical solution: a dust sealing structure for a coal conveyor belt, comprising: a conveying component, a sealing component, and a dust collection component. The upper surface of the conveying component is equipped with a sealing component for sealing dust, and the upper surface of the sealing component is equipped with a dust collection component for collecting coal dust. The conveying component includes a mounting frame 100 for mounting the conveyor belt 140. The sealing component is composed of multiple sealing covers 200. The dust collection component includes a dust collection pipe 300 for dust collection, and a dust collection head 320 is installed at the lower end of the dust collection pipe 300.
[0022] Please see Figures 1 to 3 As the first embodiment of this utility model: a plurality of support legs 110 are evenly installed on the lower surface of the mounting frame 100, and an output roller 150 is rotatably installed on the front edge and the rear edge of the inner side of the mounting frame 100 respectively. A drive motor 130 is installed on the right side surface of the front output roller 150, and a conveyor belt 140 is rotatably installed inside the mounting frame 100 through the two output rollers 150.
[0023] Multiple sets of bearing seats 120 are symmetrically installed on the lower side inside the mounting frame 100. A receiving roller is rotatably installed between two bearing seats 120. The outer surface of the receiving roller abuts against the lower surface of the conveyor belt 140. A baffle 160 is installed on the left and right edges of the upper surface of the mounting frame 100 respectively.
[0024] A feed cylinder 220 is installed on the rear edge of the upper surface of the mounting bracket 100. The upper surface of the feed cylinder 220 is designed to be open. The opening of the lower surface of the feed cylinder 220 is aligned with the upper surface of the conveyor belt 140. A cover plate 230 is hinged to the rear edge of the upper surface of the feed cylinder 220.
[0025] The lower surface of the cover plate 230 abuts against the upper surface of the feed cylinder 220. Multiple sealing covers 200 are fastened above the conveyor belt 140 by the mounting bracket 100. The multiple sealing covers 200 have the same structure and abut against each other. A sealing gasket is provided at the abutment point between the sealing covers 200.
[0026] In use, the user first aligns the coal blocks being conveyed with the opening on the upper surface of the feed cylinder 220. After alignment, the user starts the drive motor 130, which drives the conveyor wheel to rotate, thereby rotating the conveyor belt 140 between the two conveyor rollers. This conveys the coal blocks falling onto the surface of the feed cylinder 220. During conveying, the user can select a suitable length of conveyor belt 140 according to actual needs. After selecting the length, the user can then install the sealing covers 200 sequentially on the upper surface of the conveyor belt 140, so that multiple sealing covers 200 abut against each other to form a complete sealing cover 200, thus achieving a sealing effect. Since multiple sealing covers 200 can be arranged along the length and width of the conveyor belt 140 during use, they can fully cover the upper surface of the conveyor belt 140, effectively preventing dust generated during coal conveying from flying outward, reducing dust diffusion in the working environment, and improving the sealing effect.
[0027] Please see Figures 1 to 3 As a second embodiment of the present invention: a handle 201 is installed on the left and right surfaces of the sealing cover 200 respectively, a circular through hole 210 is opened at the center of the upper surface of the sealing cover 200, the circular through holes 210 are spaced apart, and the suction pipe 300 has an L-shaped structure.
[0028] The end of the suction pipe 300 away from the sealing cover 200 is connected to the vacuuming equipment. A connecting flange 310 is installed on the outer surface of the suction pipe 300. The suction pipe 300 is sealed to the circular through hole 210 through the connecting flange 310. The suction head 320 at the lower end of the suction pipe 300 is located inside the sealing cover 200.
[0029] When using the equipment, if coal blocks are being transported according to the operating steps of the first embodiment, the user can activate an external dust collection device (the dust collection device is existing technology, and its specific working principle and structure will not be described in detail here). When the dust collection device is activated, a negative pressure suction force is generated inside the dust collection pipe 300. At this time, the dust collection head 320 of the dust collection pipe 300 will also generate a negative pressure suction force. Since the dust collection head 320 is aligned with the conveyor belt 140, when dust is generated during the transport of coal blocks, it will be sucked into the dust collection pipe 300 and then discharged and collected. Due to the cooperation of the dust collection pipe 300 and the dust collection head 320, the dust inside the sealing component is continuously sucked out, so that a relative negative pressure is formed in the sealed space. This helps to prevent dust from leaking out from the gaps in the sealing cover 200. Together with the sealing component, it further improves the dust sealing effect.
[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
