Description

Technical Field

[0001] This utility model relates to the field of coal gangue screening technology, specifically to a coal gangue solid waste crushing and screening device. Background Technology

[0002] Coal-based solid waste mainly originates from various solid wastes generated during coal mining and utilization, primarily including coal gangue, coal ash, slag, and coal slime. Coal gangue is a blackish-gray sedimentary rock associated with coal seams, with a lower carbon content and higher hardness compared to coal. A common way to utilize coal gangue is in road paving. Currently, most of the coal gangue used in road paving is untreated, raw coal gangue, with complex mineral composition and extremely uneven particle size and strength, easily resulting in poor quality of the paved roads. Therefore, it is necessary to crush and sort the raw coal gangue.

[0003] The existing technology has the following problems:

[0004] 1. The existing coal gangue solid waste crushing and screening equipment does not crush the stones in a concentrated manner during the crushing process, resulting in uneven crushing of many stones. This leads to a wide range of particle sizes in the later screening process and makes the screening steps complicated.

[0005] 2. Existing coal gangue solid waste crushing and screening equipment cannot accurately screen coal gangue particles according to size, which affects the subsequent utilization of coal gangue. Utility Model Content

The two sets of rollers 73 roll and crush each other, which can crush the coal gangue from the middle of the device into the bottom of the device, achieving a better screening effect. At the same time, the bottom of the crushing device 7 is equipped with a support plate 11, which provides support and facilitates the blocking of large pieces of coal gangue, making subsequent screening more convenient. Example 3

[0029] The screening device 13 includes a screening plate 131, with multiple sets of secondary screening holes 133 on the top of the screening plate 131. A discharge pipe 132 is provided inside the screening plate 131, and the discharge pipe 132 is installed at the bottom of the secondary screening holes 133 in an inclined shape.

[0033] The working principle of this coal gangue solid waste crushing and screening device will be explained in detail below.

[0034] like Figure 1-4As shown, when this coal gangue solid waste crushing and screening device is in use, the top of the screening box 1 is fixedly connected to the support plate 2. The support plate 2 is installed on the top of the screening box 1, which can play an environmental protection role in the crushing of coal gangue and reduce coal dust flying. The top of the support cover 4 supports the drive motor 5. The drive motor 5 controls the bottom crushing rod 51 to rotate and crush, which allows the material to directly enter the device from the feed pipe 6 for crushing. Then it enters the device from the dividing hopper 31. The crushing rod 51 installed at the bottom of the drive motor 5 crushes the coal gangue. Then the crushed stones enter the top of the crushing device 7 from the bottom of the dividing hopper 31. The rotating motor 71 of the crushing device 7 drives the roller 73 to roll. Another set of rollers 73 is driven by another set of motors to roll. The two sets of rollers 73 roll and crush in opposite directions, which can crush the coal gangue from the middle of the device into the bottom of the device. To achieve better screening results, a support plate 11 is installed at the bottom of the crushing device 7. The support plate 11 provides support and facilitates the blocking of large pieces of coal gangue, allowing the crushing device 7 to repeatedly crush and stir. A pushing device 14 is installed on the top of the screening device 13. A pusher scraper 147 is installed on the top of the screening plate 131. The pusher scraper 147 is installed on both sides of the connecting component 145, and a connecting plate 144 connected at one end is connected by a threaded rod 143. After the servo motor 142 rotates, the connecting plate 144 moves left and right along the fixed box 141, causing the pusher scraper 147 to move left and right on the screening plate 131. Larger stones are pushed out from the primary sorting port 8, while smaller powdery materials enter the interior of the discharge pipe 132 through the secondary screening hole 133 and are then discharged from the interior of the secondary sorting port 9, making the device more refined and easier to use.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
