Description

Technical Field

[0001] This utility model relates to the technical field of coal preparation equipment, and more specifically, to a wind-powered coal preparation device with dust reduction effect. Background Technology

[0002] Wind-powered coal preparation devices utilize aerodynamic principles, using a fan to generate high-speed airflow to separate coal and gangue of different densities. They feature no wastewater, low energy consumption, and simple structure, making them suitable for water-scarce and environmentally friendly applications. Those with dust reduction capabilities incorporate a sealed chamber and dust collection components to minimize dust leakage and facilitate collection and filtration, retaining the advantages while reducing pollution.

[0003] Publication No. (CN220092464U) discloses a coal preparation device with a dust removal structure, including a fixed box. An inlet is provided on one end face of the fixed box, and a spray structure and a dust collection structure are also provided on the end face. An outlet is provided on the side wall of the fixed box, and a drive motor is connected to the other side wall. The left and right side walls of the fixed box are hollow. This invention utilizes a reciprocating motion structure to drive the dust removal structure to move horizontally to the left. When it reaches a bend, a connecting rod abuts against a limiting groove, causing the connecting rod to move from one end of the limiting groove to the other end, thereby driving the dust removal structure to move to the right. This allows the dust removal structure to move left and right, enabling it to brush away dust adsorbed in the inner cavity of the fixed box, resulting in better and more effective dust removal.

[0004] However, this type of coal preparation device with a dust-reducing structure has the following drawbacks: Although it can achieve dust reduction and clean the dust in the inner cavity of the fixed box, the internal humidity increases during the process of spraying water mist and absorbing dust. While still absorbing dust, the filter plate will draw in the moist air, causing impurities in the filter plate to mix with the moisture, which will clog the filter plate. This makes it impossible to quickly maintain the filter plate that filters smoke and dust, and also to achieve the effect of pre-cleaning the filter plate, thus reducing the burden of subsequent maintenance. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a wind-powered coal preparation device with dust reduction effect, so as to solve the problem that the filter plates for filtering smoke and dust cannot be quickly maintained and the filter plates can be pre-cleaned at the same time in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a wind-powered coal preparation device with dust reduction effect, comprising...

[0007] A support base is provided, with a protective cover fixedly connected to its exterior. Two processing boxes are fixedly connected to the end of the protective cover away from the support base.

[0010] The outer side of the frame is in contact with the outer side of the cleaning plate, and the end of the arc-shaped block away from the frame is in contact with the outer side of the filter plate.

[0011] The outer side of the arc-shaped locking block is slidably connected to the inner wall of the arc-shaped groove, and the end of the arc-shaped locking block away from the arc-shaped groove is fixedly connected to the outside of the S-shaped elastic element.

[0012] The pull block is slidably connected to the inner wall of the mounting groove, and the outer side of the discharge plate is in contact with the outer side of the screen plate.

[0025] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0026] Example 1: Please refer to Figures 1 to 7 This utility model provides a technical solution: a wind-powered coal preparation device with dust reduction effect, including a support base 1, a protective cover 2 fixedly connected to the outside of the support base 1, two processing boxes 3 fixedly connected to the end of the protective cover 2 away from the support base 1, a guide block 4 fixedly connected inside each of the two processing boxes 3, a frame 5 movably connected to the inner wall of the processing box 3, a filter plate 8 detachably connected to the inner wall of the frame 5, an S-shaped elastic element 6 fixedly connected to the inner wall of the frame 5, an arc-shaped locking block 7 slidably connected to the inner wall of the frame 5, a cleaning plate 12 fixedly connected to the outside of the frame 5, the outside of the frame 5 contacting the outside of the cleaning plate 12, and the end of the arc-shaped locking block 7 away from the frame 5 contacting the outside of the filter plate 8.

[0027] During the coal preparation process in the coal mine, dust will be generated through the support base 1. At this time, the fan in the protective cover 2 can draw the dust into the interior of the treatment box 3 for dust suppression. Under the influence of the guide block 4, the dust can be blown evenly into the filter plate 8, so that the dust can be filtered evenly and avoid concentrated blowing in, which would reduce the dust suppression effect. At the same time, when maintaining the filter plate 8, the S-shaped elastic element 6 and the arc-shaped clamping block 7 can achieve the effect of pre-cleaning the impurities attached to the filter plate 8, reducing the burden of subsequent maintenance.

[0028] Example 2: Based on Example 1, in order to facilitate the maintenance of the filter plate 8, multiple arc-shaped grooves 9 are provided at both ends of the filter plate 8, a pull block 11 is fixedly connected to the outside of the filter plate 8, an installation groove 10 is provided on the inner wall of the frame 5, the outside of the arc-shaped locking block 7 is slidably connected to the inner wall of the arc-shaped groove 9, and the end of the arc-shaped locking block 7 away from the arc-shaped groove 9 is fixedly connected to the outside of the S-shaped elastic member 6.

[0029] During maintenance of the filter plate 8, the frame 5 is swung 90 degrees. Then, the filter plate 8 is pulled out of the frame 5 by pulling the pull block 11. When the filter plate 8 is pulled, the arc grooves 9 on both sides of the filter plate 8 and the arc-shaped locking blocks 7 work together to continuously squeeze the S-shaped elastic element 6, causing the S-shaped elastic element 6 to release space. This allows the arc-shaped locking blocks 7 to slide along the outside of the arc grooves 9. The arc-shaped locking blocks 7 can continuously impact the filter plate 8, and the cleaning plate 12 can clean stubborn impurities inside the holes of the filter plate 8 from the outside. This enables the quick disassembly of the filter plate 8 for subsequent maintenance, and also achieves a pre-cleaning effect on the impurities attached to the filter plate 8, reducing the burden of subsequent maintenance.

[0030] Example 3: Based on Example 2, in order to facilitate the guidance of smoke and dust, a screen plate 13 is fixedly connected to the inner wall of the support base 1, a discharge plate 14 is fixedly connected to the outside of the support base 1, a discharge plate 15 is fixedly connected to the outside of the support base 1, a feed bin 16 is fixedly connected to the outside of the support base 1, the filter plate 8 is slidably connected to the inner wall of the mounting groove 10, the pull block 11 is slidably connected to the inner wall of the mounting groove 10, the outside of the discharge plate 14 is in contact with the outside of the screen plate 13, the outside of the discharge plate 15 is in contact with the outside of the screen plate 13, and the outside of the frame 5 is in contact with the outside of the processing box 3.

[0031] When coal is poured into the feed hopper 16, the vibration of the support base 1 and the blowing of the fan cause the gangue in the coal to separate from the coal. The gangue will be discharged from the discharge plate 14, while the lighter coal will be continuously moved towards the discharge plate 2 15 under the action of the fan and vibration and then discharged from the discharge plate 2 15. During this process, dust will be generated. At this time, the fan in the protective cover 2 is activated to draw the smoke and dust into the processing box 3. The guide block 4 in the processing box 3 can guide the smoke and dust and blow it evenly onto the filter plate 8 for filtration, avoiding the blockage caused by the smoke and dust being blown into a local area. In this way, the dust generated during coal preparation is reduced.

[0032] The working process of this utility model is as follows:

[0033] First, the coal is poured into the feed hopper 16. Under the vibration of the support base 1 and the blowing of the fan, the gangue in the coal is separated from the coal. The gangue is discharged from the discharge plate 14, while the lighter coal, under the action of the fan and vibration, moves towards the discharge plate 15 and is then discharged from it. During this process, dust is generated. The fan in the protective cover 2 is then activated, drawing the dust into the treatment box 3. The guide blocks 4 in the treatment box 3 guide the dust evenly towards the filter plates 8 for filtration, preventing dust from concentrating in a localized area and causing blockage. This achieves dust reduction during coal preparation. Meanwhile, when maintaining the filter plate 8, the frame 5 is swung 90 degrees, and the filter plate 8 is pulled out of the frame 5 by pulling the pull block 11. When the filter plate 8 is pulled, the arc grooves 9 on both sides of the filter plate 8 and the arc-shaped locking blocks 7 cooperate to make the arc-shaped locking blocks 7 continuously squeeze the S-shaped elastic element 6, so that the S-shaped elastic element 6 releases space. This satisfies the requirement that the arc-shaped locking blocks 7 slide along the outside of the arc grooves 9. The arc-shaped locking blocks 7 can continuously impact the filter plate 8, and the cleaning plate 12 can clean the stubborn impurities inside the holes of the filter plate 8 from the outside. This realizes the quick disassembly of the filter plate 8 for subsequent maintenance, and at the same time, it can achieve the effect of pre-cleaning the impurities attached to the filter plate 8, reducing the burden of subsequent maintenance.
