DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0029] Embodiment:

[0030] With reference to Figures 1-5 A dust prevention device for coal block crushing in a thermal power plant, comprising a support 1, a crushing seat 2 connected to the support 1, a drive rod 201 rotatably connected to the crushing seat 2, and a crushing roller 2011 connected to the drive rod 201, further comprising:

[0031] A dustproof box 3 fixedly connected to the crushing seat 2;

[0032] A feed pipe 4 fixedly connected to the dustproof box 3;

[0033] A discharge pipe 101 fixedly connected to the bottom of the crushing seat 2;

[0034] An air suction pump 5 fixedly connected to the dustproof box 3;

[0035] An air suction pipe 6 fixedly connected to the driving end of the air suction pump 5;

[0036] The end of the air suction pipe 6 away from the air suction pump 5 is in communication with the feed pipe 4.

[0037] The filter screen 601 is fixedly connected in the air suction pipe 6.

[0038] The pressure storage cylinder 8 is fixedly connected in the dustproof box 3, the back flushing pipe 9 is fixedly connected to the pressure storage cylinder 8, and the gas outlet end of the back flushing pipe 9 faces the filter screen 601.

[0039] The drive cylinder 7 is also fixedly connected in the dustproof box 3, the sliding plug 702 is slidingly connected in the drive cylinder 7, the gas delivery pipe 801 is fixedly connected to the drive cylinder 7, and the end of the gas delivery pipe 801 away from the drive cylinder 7 is in communication with the pressure storage cylinder 8.

[0040] The feeding pipe 4 is rotationally connected with a rotating shaft 401, and the rotating shaft 401 is fixedly connected with a push plate 4011. The driving cylinder 7 is slidably connected with a sliding rod 703, and the sliding rod 703 is fixedly connected with the sliding plug 702. The end of the sliding rod 703, which is away from the sliding plug 702, is abutted against the push plate 4011.

[0041] With reference to Figure 4 The driving cylinder 7 is connected with an air inlet pipe 701, and the air inlet pipe 701 and the air outlet pipe 801 are both provided with a one-way valve.

[0042] The rotating shaft 401 is fixedly connected with a driving plate 402.

[0043] The driving plate 402 is fixedly connected with a first spring 4021, and the end of the first spring 4021, which is away from the driving plate 402, is fixedly connected to the inner side wall of the feeding pipe 4.

[0044] With reference to Figure 4 The first spring 4021 arranged on the driving plate 402 can effectively push the driving plate 402 to reset when the coal blocks fall.

[0045] The sliding rod 703 is sleeved with a second spring 7031.

[0046] With reference to Figure 4 The second spring 7031 arranged on the sliding rod 703 can pull the sliding plug 702 to quickly reset.

[0047] With reference to Figures 1-5 In use, the coal blocks are sequentially poured into the feeding pipe 4. The coal blocks in the feeding pipe 4 sequentially fall. The coal blocks impact the driving plate 402 in the falling process. The driving plate 402 rotates under the impact. The driving plate 402 rotates to drive the push plate 4011 to rotate. The push plate 4011 rotates to drive the sliding rod 703 to move upwards. The sliding rod 703 moves upwards to synchronously drive the sliding plug 702, which is fixedly connected with the sliding rod 703, to slide. The sliding plug 702 slides to press the gas in the driving cylinder 7. The gas in the driving cylinder 7 enters the pressure accumulating cylinder 8 through the air outlet pipe 801. The gas in the pressure accumulating cylinder 8 is stored in the pressure accumulating cylinder 8.

[0048] With reference to Figure 3 The input coal blocks are crushed under the action of the rotating crushing roller 2011. The crushed coal powder is discharged through the discharge pipe 101.

[0049] With reference to Figures 2-5 In the process of conveying the coal blocks and crushing the coal blocks, the worker can start the air suction pump 5. The air suction pump 5 will extract the air and dust, which are diffused through the feeding pipe 4, through the air suction pipe 6.

[0050] It should be noted that the outlet end of the air suction pipe 6 can be connected with a dust collecting box, thereby collecting the extracted dust.

[0051] Through the air suction pump 5 and the air suction pipe 6 arranged in the device, the escaped dust gas can be effectively extracted, thereby effectively preventing the dust gas from escaping into the air, ensuring that the surrounding environment is not polluted during the production process and ensuring the physical health of the production workers.

[0052] Referring to Figure 2 , Figure 5 After a period of air suction, the worker can open the pressure relief valve on the back blowing pipe 9, at which time the gas in the pressure accumulating cylinder 8 will be instantaneously sprayed out through the back blowing pipe 9, and the gas sprayed out through the back blowing pipe 9 will blow against the filter screen 601, thereby effectively blowing off the dust particles adhered and clogged on the filter screen 601, thereby ensuring the air suction effect of the mesh holes on the filter screen 601.

[0053] It should be noted that during the back blowing process, the air suction pump 5 can be temporarily stopped to ensure that the back blowing pipe 9 can effectively blow off the dust particles on the filter screen 601.

[0054] The above is only a preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
