[0002] Clean coal refers to coal products that have been processed by mechanical methods using selected low-sulfur and low-volatile anthracite powder to which adhesives, combustion aids, sulfur fixation, waterproofing and other additives have been added. Clean coal does not require drying and can solidify naturally. After packaging, it will not break or pollute during storage and transportation, and it is smokeless, odorless and dust-free during combustion, allowing different stoves to achieve clean emissions. Therefore, clean coal will receive widespread attention in the future.

[0003] After the clean coal is processed, the overall quality of the clean coal is uneven.

[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0025] like Figures 1 to 5 As shown, a clean coal quality separation device comprises a mounting frame 1, a sieve plate 4 is movably provided on the surface of the mounting frame 1, three groups of sieve holes 5 are provided on the surface of the sieve plate 4, the sizes of the three groups of sieve holes 5 gradually increase, the size of the sieve holes 5 on one side away from the sieve plate 4 is larger than the size of the sieve holes 5 on the other side, and an oscillation unit is installed on the side wall of the mounting frame 1, and the oscillation unit is used to oscillate the sieve plate 4;

[0026] The oscillation unit includes a cam 11, a limit slider 14 is slidably installed on the outer surface of the cam 11, a vertical rod 15 is vertically installed on the top of the limit slider 14, and the vertical rod 15 is in a vertical state. An arch bracket 17 is installed at the bottom of the screen plate 4, and the bottom of the vertical rod 15 is slidably connected to the arch bracket 17.

[0027] A sieve plate is installed with gradually increasing sieve holes. When the cam of the oscillation unit rotates, the limit slider on the cam surface is driven to move up and down, and the bottom sieve plate is driven to oscillate and rotate synchronously through the vertical rod. During the oscillation and rotation process, the sieve plate oscillates as a whole, thereby achieving the purpose of screening. During the oscillation, the entire sieve plate is in an inclined state, so that the material can move on the sieve plate, reducing the occurrence of pushing on the sieve plate, and can automatically move to different sieve holes, facilitating screening and separation.

[0028] like Figures 1 to 5As shown, in a specific embodiment, three discharge ports 2 are provided at the bottom of the mounting frame 1, and conveyor belts 3 are installed inside the three discharge ports 2. The bottom of the conveyor belt 3 corresponds to the vertical position of the three groups of sieve holes 5. Different sizes of raw materials are screened through different sieve holes 5, and the screened raw materials are transported outward through the conveyor belt 3 at the bottom, while the raw materials on the surface that cannot be successfully screened are discharged through the inclined discharge port 10.

[0029] like Figures 1 to 5 As shown, further, a rotating shaft 7 is fixedly installed on one side of the sieve plate 4, and both ends of the rotating shaft 7 are movably installed on the inner wall of the mounting frame 1, and two blocking plates 6 are installed on the side wall of the sieve plate 4, each blocking plate 6 blocks two adjacent sieve holes 5, and the blocking plate 6 is in a convex state. A fence 8 is installed on the outer surface of the sieve plate 4, and the fence 8 is C-shaped. A guide block 9 is installed at the end of the fence 8, and the guide block 9 is in an inclined state. A discharge port 10 is opened inside the end of the guide block 9. The successfully screened raw materials are discharged through the inclined discharge port 10. The fence 8 reduces the possibility of scattering of raw materials.

[0030] like Figures 1 to 5 As shown, the outer wall of the cam 11 is provided with two cam grooves 13, and a limit slider 14 is slidably installed on the surface of each cam groove 13. The central axis of the cam 11 movably penetrates the side wall of the mounting frame 1, and a driving motor 12 is installed on the outer wall of the mounting frame 1. The output shaft of the driving motor 12 is fixedly connected to the central axis of the cam 11. When the driving motor 12 is started, the cam 11 connected to the output shaft is driven to rotate by the driving motor 12.

[0031] like Figures 1 to 5 As shown, a notch 18 is provided inside the arch support 17, and a vertical rod 15 is slidably installed inside the notch 18. A sliding rod 16 is installed on the top of the vertical rod 15, and the sliding rod 16 slides on the inner wall of the arch support 17. A limit plate 19 is installed horizontally on the outer wall of the vertical rod 15, and a limit rod 20 is installed on both sides of the limit plate 19, and the bottom of the limit rod 20 is welded to the base of the inner cavity of the installation frame 1. The cam 11 rotates, and a cam groove 13 is provided on the surface of the cam 11, and a limit slider 14 is slidably installed on the surface of the cam groove 13, and the rotation of the limit slider 14 is limited by the limit rod 20, which eventually causes the limit slider 14 to move up and down as the position of the cam groove 13 changes, and in the process of the limit slider 14 moving up and down, the top vertical rod 15 is pushed to move up and down, driving the sliding rod 16 at the end of the vertical rod 15 to slide on the arch support 17, driving the entire screen plate 4 to shake continuously.

[0032] The implementation principle of a clean coal mass separation device in this embodiment is as follows:

[0033] When normal screening is required, the raw materials need to be poured onto the surface of the leftmost sieve plate 4 first, and then the user needs to start the driving motor 12, and the cam 11 connected to the output shaft is driven to rotate by the driving motor 12, and a cam groove 13 is provided on the surface of the cam 11, and a limit slider 14 is slidably installed on the surface of the cam groove 13, and the rotational movement of the limit slider 14 is limited by the limit rod 20, which eventually leads to the change of the position of the cam groove 13, driving the limit slider 14 to move up and down, and in the process of the limit slider 14 moving up and down, the top vertical rod 15 is pushed to move up and down, driving the slide bar 16 at the end of the vertical rod 15 to slide on the arch bracket 17, driving the entire sieve plate 4 to shake continuously, and when the sieve plate 4 is shaking, the angle of the sieve plate 4 is tilted, so that the raw materials on the surface of the sieve plate 4 roll down continuously, and different raw material sizes are screened through different sieve holes 5, and the screened raw materials are transported outward through the conveyor belt 3 at the bottom, while the raw materials on the surface that cannot be screened successfully are discharged through the inclined discharge port 10.
