Abstract
Description
Technical Field
[0001] This utility model relates to the field of coal washing equipment technology, and in particular to a coal washing device. Background Technology
[0002] Coal is a solid combustible mineral formed gradually from ancient plants buried underground through complex biochemical and physicochemical changes. Known as "black gold" and the "food of industry," coal has been one of the world's primary energy sources since the 18th century. While its value has diminished considerably in the 21st century, it will remain an indispensable energy source for human production and daily life for a considerable period. The supply of coal is also crucial to the stability of my country's industrial development and all aspects of society.
[0003] In related technologies, existing coal washing devices typically place raw coal on a filter screen and clean it using a spraying device. Because the raw coal is directly poured onto the filter screen, the bottom layer of raw coal cannot be rinsed by the spray liquid. At the same time, the nozzle is fixed, and the spray liquid can only be sprayed onto the surface of the raw coal at a fixed angle, which greatly reduces the cleaning effect of the raw coal. Therefore, we propose a coal washing device.
[0004] The information disclosed in this background section is only for understanding the background technology of the inventive concept, and therefore may include information that does not constitute prior art. Utility Model Content
[0005] The purpose of this invention is to provide a coal washing device to solve the problems mentioned in the background art. Existing coal washing devices typically place raw coal on a filter screen and use a spraying device to clean it. Because the raw coal is directly poured onto the filter screen, the bottom layer of raw coal cannot be rinsed by the spray liquid. At the same time, the nozzle is fixed, and the spray liquid can only be sprayed onto the surface of the raw coal at a fixed angle, resulting in a significant reduction in the cleaning effect of the raw coal.

The left side of the rotating stud 25 is rotatably mounted inside a movable sleeve 10, and the right side of the rotating stud 25 penetrates the wall of the housing 1 and is connected to the left output end of a first motor 6. The first motor 6 is fixedly mounted on the upper right side of the housing 1. A mounting block 4 is threadedly engaged on the outer side of the rotating stud 25. The feeding box 2 is welded and fixedly mounted on the upper end of the mounting block 4. A feed pipe 3 is connected to the upper end of the feeding box 2, and a feeding pipe 5 is connected to the lower end of the feeding box 2. A through hole 24 is opened on the mounting block 4 at the corresponding position of the feeding pipe 5. The housing 1 is fixedly mounted with... A perforated support plate 11 is provided, with its left and right sides connected and fixed to the inner wall of the outer casing 1. Three sets of stirring shafts 8 are horizontally installed above the perforated support plate 11 inside the outer casing 1. The left side of the stirring shaft 8 is rotatably mounted inside the movable sleeve 10, and the right side of the stirring shaft 8 passes through the wall of the outer casing 1 and is connected to the output end of the second motor 7. Multiple sets of stirring blades 9 are welded and fixed at intervals on the side of the stirring shaft 8. The lower end of the stirring blades 9 is attached to the upper end face of the perforated support plate 11. The stirring blades 9 flip the coal blocks above the perforated support plate 11, improving the cleaning effect of the coal blocks. The position of the feeding box 2 can be adjusted by the first motor 6 and the rotating stud 25 to make the coal blocks evenly distributed on the perforated support plate 11.
[0024] In specific implementation of the embodiments of this utility model, such as Figure 1 , 2 As shown, a spray pipe 17 is installed at the upper end of the device housing 1 at the front end of the feeding box 2. Multiple spray heads are installed at intervals at the lower end of the spray pipe 17. The left side of the spray pipe 17 penetrates the wall of the device housing 1 and is connected to the inside of the storage box 15. The coal blocks on the upper end of the hollow support plate 11 are sprayed and cleaned through the spray pipe 17 and the spray heads.
[0025] In specific implementation of the embodiments of this utility model, such as Figure 1 , 2As shown, a spray pump 18 is installed on the spray pipe 17, and the storage tank 15 is filled with cleaning fluid 16. An observation window 22 is installed at the front end of the storage tank 15. A water supply pipe and a drain pipe are connected to the storage tank 15. A connecting pipe 13 is connected to the lower right end of the storage tank 15. The right side of the connecting pipe 13 is connected to the lower end of the device housing 1. A filter screen 12 is installed at the contact position between the connecting pipe 13 and the device housing 1. A circulation pump 14 is installed on the connecting pipe 13. The cleaning fluid 16 is recycled through the connecting pipe 13 and the circulation pump 14, thus saving resources.
[0026] In specific implementation of the embodiments of this utility model, such as Figure 1 , 3 As shown, discharge ports 19 are symmetrically installed at the front and rear ends of the device housing 1. Synchronous telescopic columns 20 are installed at intervals on the discharge ports 19. Push plates 23 are fixedly installed on the movable ends of the synchronous telescopic columns 20. The lower end of the push plate 23 is fitted to the upper end surface of the hollow support plate 11. A controller 21 is installed at the front end of the device housing 1 below the discharge port 19. The push plate 23 pushes the coal blocks located at the edge of the hollow support plate 11 to the stirring blades 9, thereby improving the cleaning effect on the coal blocks.
[0027] In this embodiment, raw coal is fed into the feeding box 2 through the feed pipe 3. Driven by the rotating screw 25 and the first motor 6, the feeding box 2 can move left and right inside the outer casing 1 of the device to adjust the feeding amount and position, ensuring that the coal blocks fall evenly onto the perforated support plate 11. The stirring blades 9 tumble and agitate the coal blocks above the perforated support plate 11, improving the cleaning effect. The spray pipe 17 and spray head spray and clean the coal blocks at the top of the perforated support plate 11, removing surface clay and mud, improving coal quality and utilization. The cleaning solution 16 is circulated through the connecting pipe 13 and the circulating pump 14. The system recycles coal, saves resources and costs, and reduces environmental pollution. The pusher plate 23 pushes the coal block located at the edge of the hollow support plate 11 to the stirring blade 9, improving the cleaning effect of the coal block. Then, the cleaned coal block is transported out through the discharge port 19. The pusher plate and synchronous telescopic column at the front end of the device shell are installed on the discharge port. When discharge is required, the discharge port 19 is removed, and the pusher plate 23 and synchronous telescopic column 20 at the rear end of the device shell 1 work to discharge the raw coal from the device shell 1. The length of the synchronous telescopic column 20 at the rear end of the device shell 1 ensures that the pusher plate 23 at the rear end can smoothly push the raw coal out of the device shell 1.
