Description

Technical Field

[0001] The utility model belongs to the field of coal mines, and in particular relates to a vibrating screen based on the anti-splashing function of coal slag and coal slurry. Background Art

[0002] Vibrating screens are widely used in the coal and other industries for grading, washing, dehydrating, and removing media from coal slag and coal slurry. Linear vibrating screens are widely used due to their high production efficiency, excellent grading performance, and easy maintenance. During operation, the dynamic performance of the vibrating screen directly affects its screening efficiency and service life. The vibrating screen utilizes a vibrating motor as a vibration source, causing the coal slag and coal slurry to be thrown onto the screen while simultaneously moving forward in a linear motion. The coal slag and coal slurry enter the screening machine's feed port evenly from the feeder, passing through multiple layers of screens to produce oversize and undersize materials of varying sizes, which are then discharged from their respective outlets.

[0003] There are still some problems in the actual use of existing vibrating screens. For example, when the coal-water mixture enters the vibrating screen, the coal-water mixture will splash outward, thereby possibly contaminating the vibrating screen device and the surrounding environment.

[0016] One of the vibrating screens based on the anti-splashing function of coal slag and coal slurry also includes an anti-splashing water equalization component 13, and the anti-splashing water equalization component 13 is fixedly connected to the upper left side of the screening box 4, which is conducive to achieving the effect of preventing coal slag and coal slurry from splashing, and can effectively avoid the problem of coal-water mixture splashing outward, thereby avoiding the problem of pollution of the environment near the vibrating screen.

[0017] In this embodiment, combined with the Figure 3 As shown, the splash-proof water-equalizing component 13 includes a splash-proof cover 131, and the inner left opening of the splash-proof cover 131 is integrally connected with a water-equalizing tank 132, and the inner lower right side of the water-equalizing tank 132 is provided with a water outlet 133; the inner middle and upper sides of the water-equalizing tank 132 are fixedly connected with water-equalizing plates 134 in sequence from left to right, and the lower sides of the water-equalizing plates 134 are tilted to the right; the openings in the middle of the left side of the water-equalizing tank 132 are fixedly connected with water inlet pipes 135 in sequence from front to back, and the water inlet pipes 135 are all located on the upper side of the splash-proof cover 131.

[0018] In this embodiment, specifically, the splash-proof cover plate 131 is fixedly connected to the upper left side of the screening box 4 .

[0019] In this embodiment, specifically, the water averaging tank 132 is located inside the screening box 4 .

[0020] In this embodiment, specifically, the splash-proof cover plate 131 is a stainless steel plate with a rectangular cross section.

[0021] In this embodiment, specifically, the water averaging tank 132 is a stainless steel box with a rectangular cross section.

When the coal-water mixture enters the interior of the water equalizing tank 132, part of the coal-water mixture can be blocked by the water equalizing plate 134, and the blocked coal-water mixture will flow to the front and back sides of the interior of the water equalizing tank 132, so that the coal-water mixture is evenly distributed in the water equalizing tank 132. Then, when the coal-water mixture is discharged onto the screen 7 through the water outlet 133, the coal-water mixture can be more evenly distributed on the screen 7, thereby improving the utilization rate of the screen 7; because the anti-splash cover 131 blocks the vicinity of the water outlet 133, it can effectively avoid the problem of the coal-water mixture splashing outwards, and thus effectively avoid the problem of the coal-water mixture polluting the environment near the vibrating screen, thereby achieving the effect of preventing coal slag coal slurry from splashing.
