Technical Field
[0001] The utility model relates to the technical field of coal ash collection, and specifically to a coal ash compacting and collecting device for a thermal power plant. Background Art
[0002] Fly ash is the main solid waste discharged from coal-fired power plants. With the development of the electric power industry, the fly ash emissions from coal-fired power plants have increased year by year, becoming one of the largest industrial waste residues in my country. If a large amount of fly ash is not treated, it will generate dust and pollute the atmosphere. If it is discharged into the water system, it will cause river siltation. Therefore, we propose a coal ash compaction and collection device.

The fly ash collection device can isolate the fly ash inside the chassis by setting the filter column, so that the clean gas is discharged to the outside, and the purpose of filtering the gas is achieved.
[0004] The above technical solution uses scraper plates, filter screens and other methods to transport the coal ash into the collection box. The coal ash easily floats in the box and remains above the scraper plates, which makes cleaning more complicated. The collection device is too simple and is not conducive to collecting more fixed waste of coal ash. Therefore, we propose a coal ash compaction collection device for thermal power plants.

[0024] Embodiment 1, as Figure 1-5 As shown, the utility model provides a coal ash compacting and collecting device for a thermal power plant, comprising a workbench 1, a hydraulic device 3, a water tank mechanism 5 and a collecting device 4. A box body 2 is arranged above the workbench 1, a coal ash air inlet pipe 9 is arranged on the left side of the box body 2, and a first filter screen 10 is arranged inside the air inlet end of the coal ash air inlet pipe 9. The first filter screen 10 is convenient for filtering some larger unburned coal, and the coal ash is driven into the coal ash air inlet pipe 9 by the action of an external fan. A controller 8 is arranged on the right end of the surface of the workbench 1, and a second filter screen 11 and an air outlet 12 are arranged on the top of the box body 2.
[0025] The following is a detailed description of the specific settings and functions of its collection device, hydraulic device and water tank mechanism.
[0026] like Figure 1 and Figure 4 , Figure 5 As shown, the hydraulic device 3 includes two symmetrically arranged hydraulic lifts 31, both of which are fixedly installed on the surface of the workbench 1, and the output ends of the two hydraulic lifts 31 are commonly fixedly connected with a compacting plate 32, and a first through hole 33 is opened at the center of the compacting plate 32. The compacting plate 32 is arranged at the bottom of the workbench 1 and does not abut against the frame of the collection box 407. The collecting device 4 includes a fixed plate 401, and the fixed plate 401 is fixedly installed on the front surface of the workbench 1. The surface of the fixed plate 401 is fixedly connected with a first telescopic spring 402, and one end of the first telescopic spring 402 away from the fixed plate 401 is fixedly connected with a sleeve rod 404. The bottom of the fixed plate 401 is fixedly connected with a fixed rod 403, and the fixed rod 403 is inserted into the surface of the first telescopic spring 402 and is slidably connected thereto. One end of the fixed rod 403 away from the fixed plate 401 is inserted into the inner wall of the sleeve rod 404 and is slidably connected to the bottom surface of the workbench 1 is fixedly connected to two symmetrically arranged slide rails 405, and the inner sliding connection of the two slide rails 405 is connected with a slider 406, and the surfaces of the two sliders 406 are commonly fixedly connected to a collection box 407, and the surface of the collection box 407 is fixedly connected to a stop block 408, and the stop block 408 is abutted against the surface of the sleeve rod 404, and the surface of the stop block 408 is fixedly connected to a second telescopic spring 409, and the surface of the second telescopic spring 409 is fixedly connected to a limiting rod 410, which is inserted into the inner wall of the stop block 408 and is slidably connected to the same, and the end of the limiting rod 410 away from the second telescopic spring 409 is fixedly connected to a pull rod 411, and the pull rod 411 is abutted against the surface of the stop block 408.
[0027] The effect achieved by the entire device is that, by setting the collecting device 4 and the hydraulic device 3, when it is necessary to compact and collect the coal ash, first pull the pull rod 411 to drive the limit rod 410 to slide in the same direction, and the second telescopic spring 409 is deformed, so that the collection box 407 is slid parallel to the workbench 1 through the slide rail 405, and the sleeve rod 404 is pulled. When the sleeve rod 404 abuts against the block 408, the pull rod 411 is released, the second telescopic spring 409 is reset, and the limit rod 410 is reset. The sleeve rod 404 is released, and the first telescopic spring 402 is reset to complete the fixing of the collection box 407. When a certain amount of coal ash is collected in the collection box 407, the hydraulic lift 31 drives the compacting plate 32 to descend, and the coal ash in the collection box 407 is compacted to facilitate more collection.
[0028] like Figure 1 and Figure 2 , Figure 3 As shown, the water tank mechanism 5 includes a water tank body 51, which is fixedly mounted on the front surface of the box body 2. The output end of the water tank body 51 extends to the interior of the box body 2 through a water pump and is connected to a water pipe 52. The outer surface of the water pipe 52 is provided with a plurality of spray holes 53 distributed at equal distances.
[0029] The effect achieved by the entire device is that during the collection process, the water pump works to transport the water inside the water tank body 51 to the water pipe 52 inside the box body 2, and then sprays it out through the spray hole 53 on the surface of the water pipe 52, so that the water source and the coal ash are mixed, and then fall to the bottom of the box body 2, and fall into the collection box 407 through the second through hole 13, so as to avoid the coal ash floating inside the box body 2 as much as possible, and then the filtered gas is dissipated through the second filter screen 11 and the air outlet 12.
[0030] Embodiment 2 is different from embodiment 1 in that Figure 1 As shown, the four corners of the bottom of the workbench 1 are fixedly connected with support columns 6, and the bottoms of the four support columns 6 are installed with rollers 7. Installing the rollers 7 facilitates the movement of the entire device. A second through hole 13 is opened at the center of the bottom of the box body 2, and the second through hole 13 and the output end of the coal ash inlet pipe 9 are in the same vertical direction, which is convenient for directly transporting the coal ash into the collection box 407. The controller 8 is electrically connected to the hydraulic lift 31 and the water pump.
[0031] The overall working principle is as follows: the utility model is a coal ash compacting and collecting device for thermal power plants. First, the hydraulic lift 31, the water pump and the controller power supply are connected, the water pump and the external fan are turned on to allow the coal ash to enter the box through the coal ash air inlet pipe 9. At this time, the spray hole 53 on the surface of the water pipe 52 sprays water into the box 2, and the floating coal ash combines with the water source. Then, the filtered gas is emitted through the second filter screen 11 and the air outlet 12. The collected coal ash enters the collection box 407 through the second through hole 13 and the first through hole 33. When a certain amount of coal ash is collected in the collection box 407, the hydraulic lift 31 drives the compacting plate 32 to descend, compacting the coal ash in the collection box 407 to facilitate more collection. When the collection box 407 is full, the pull rod 411 is pulled to separate the limit rod 410 from the sleeve rod 404. Then the slider 406 on the surface of the collection box 407 slides out from the slide rail, and the collected coal ash can be taken out.
[0032] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
