Description

Technical Field

[0001] The invention relates to the technical field of coal gangue processing, and in particular to a coal gangue high-efficiency crushing and processing device suitable for use in a coal mine well construction process. Background Art

[0002] Gangue is a rock with dry ash content greater than 50% produced during the construction of coal mines, development and excavation, coal mining and coal washing, and its emission accounts for about 10% to 20% of coal production. Gangue solid waste occupies a large amount of land resources, causing serious environmental damage and causing varying degrees of pollution to the atmosphere, water sources, soil, etc. Gangue is a solid waste discharged during the coal mining and coal washing process. It is a black-gray rock with a low carbon content and harder than coal that is associated with coal seams during the coal formation process. It includes excavation gangue during tunnel excavation, gangue mined from the roof, floor and interlayer during mining, and washed gangue picked out during coal washing. China has accumulated about 1,000 Mt of gangue over the years, and continues to emit about 100 Mt every year. It not only accumulates and occupies land, but also can spontaneously combust to pollute the air or cause fires.

[0003] Therefore, it is necessary to crush the coal gangue and produce cement and other building materials from the processed coal gangue, turning waste into treasure and alleviating the pollution caused by coal gangue.

[0004] The patent application with application number CN202210117571.8 provides a coal gangue sorting and crushing device, which realizes the crushing of coal gangue mixture by setting a crushing mechanism above the bottom plate and setting two synchronously oppositely moving toothed rollers in the crushing mechanism. However, although this technology has achieved the goal of improving the efficiency of coal gangue crushing to a certain extent, there are some problems: first, the transportation of coal gangue is inconvenient, which increases the cost of coal gangue processing; second, coal gangue placed in the open air is easy to agglomerate, which affects the later crushing effect; third, the crushing method is single, and the coal gangue cannot be refined; fourth, the device shakes a lot when crushing, which is easy to cause noise pollution.

[0040] Working principle: When in use, the first drive motor 7 is started, and the rotating shaft 71 drives the gangue processor 8 to rotate 90° counterclockwise to enter the stone-taking operation state, and the user moves the device to the open-air gangue site;

[0041] Next, the second drive motor 811 is started, the stone taking screw rod 812 starts to rotate at a uniform speed, the stone taking semi-sliding door 10 moves outward along the stone taking screw rod 812, and the third drive motor 9 installed on the upper part of the stone taking semi-sliding door 10 moves out to the stone taking barrel section 81, and then the third drive motor 9 is started, the third drive motor 9 drives the rotating rod 91 to rotate, the rotating rod 91 drives the three sets of loosening shafts 92 to rotate, and then the stone taking barrel section 81 is inserted into the coal gangue pile, and the loosening shaft 92 loosens the agglomerated coal gangue that is about to enter the stone crushing barrel section 82;

[0042] The loosened gangue enters the stone removing barrel section 81, the device moves backward, the gangue processor 8 moves out of the gangue pile, the first drive motor 7 is started in reverse, the shaft 71 drives the gangue processor 8 to rotate 100° clockwise, the gangue in the stone removing barrel section 81 enters the coarse crushing barrel 821, then the shaft 71 drives the gangue processor 8 to rotate 10° counterclockwise, and the gangue processor 8 is in a vertical state, so that the gangue processor 8 enters the stone crushing operation state.

[0043] When the first drive motor 7 starts, the electromagnetic seat 62 starts synchronously, and the electromagnetic seat 62 is energized to generate magnetism, so as to move the bracket 65 at the bottom of the adsorption slide 64 upward out of the horizontal U-shaped fixed groove 61.

[0045] Then, the fourth drive motor 12 is started, and the fourth drive motor 12 drives multiple groups of crushing rods 122 to perform rough processing on the incoming coal gangue. The coarse stones that meet the requirements pass through the disc screen 13 and enter the fine crushing cylinder 822. The stones fall on the disc screen 13, causing the disc screen 13 to shake up and down driven by the shaking spring 132, thereby improving the efficiency of the coarse stones that meet the requirements passing through the disc screen 13 and preventing the coarse stones that do not meet the requirements from clogging the disc screen 13.
