Description

Technical Field

[0001] The utility model relates to the technical field of coal washing, in particular to a large-particle-size coal washing device. Background Art

[0002] Coal washing is the process of physically or mechanically removing impurities (such as ash, ore, wood chips, and ironware) that may have entered the coal during its generation, mining, and transportation, thereby changing its shape and particle size and improving its quality. This process not only removes impurities from the raw coal but also separates high-quality and low-quality coal, making it a crucial industrial process.

[0003] Most of the large-particle coal washing equipment currently in use cannot turn over the large-particle coal when it is moved. Due to the large volume of large-particle coal, it will not be easily turned over when it is moved, and the surface underneath it cannot be cleaned. This will cause the surface of one side of the coal to be unable to be effectively cleaned, thereby reducing the washing effect. In addition, a small amount of small-particle coal will remain in the large-particle coal during the washing process. The washing equipment cannot collect this part of the coal, and this part of the coal will be treated together with the sewage, thereby reducing the overall coal processing benefits.

[0027] Working principle: When washing coal, turn on the stepper motor 81, and the rotating rod 82 can be rotated under the action of the stepper motor 81. When the rotating rod 82 rotates, it can drive the installation sleeve 83 to rotate, and then the installation sleeve 83 rotates to rotate the dial plate 84. Next, the dial plate 84 rotates to turn over the large-particle coal passing through. Under this action, the side where the large-particle coal contacts the surface of the transmission plate 4 can be cleaned. When the small-particle coal dropped from the discharge shell 9 through the second filter trough 11 is sufficient, the hydraulic rods 141 on both sides are turned on. Under the action of the hydraulic rods 141, the sleeves 142 on both sides can be raised. When the sleeves 142 rise, the cross bar 143 can be driven to rise. Then the rise of the cross bar 143 can drive the fixing frame 144 to rise. Next, the fixing frame 144 The rise can drive the filter plate 145 to rise, and when the filter plate 145 rises, the fence 146 can be driven to rise. At the same time, when the filter plate 145 rises, the fixing rod 147 can be driven to rise. Then, when the fixing rod 147 rises to the maximum distance along the inner wall of the slide 15, the fixing frame 144 can be rotated along the surface of the shell 142. Then, when the fixing frame 144 rotates, the filter plate 145 can be rotated. When the filter plate 145 rotates and tilts, the small-particle coal above the filter plate 145 can fall into the interior of the aggregate box 20. At the same time, when the filter plate 145 rotates, the fence 146 can be tilted. When the fence 146 tilts, the fixed blocks 16 on both sides can slide along the inner walls on both sides of the guide plate 17. Under this action, the fence 146 can be guided and limited.
