Description

Technical Field

[0001] The utility model relates to the technical field of wind coal separation devices, and more specifically, to a wind coal separation device. Background Art

[0002] Wind coal separation means that people use the principle of judging the quality of coal by its weight, generate wind with equipment, and screen the quality of coal according to the magnitude of the wind. A wind coal separation device is a device used to realize the function of wind coal separation.

[0003] For example, a wind coal separation device proposed in the patent with the publication number CN107983646B includes a frame, a wind separation device and a dust removal device. The wind separation device includes a coal throwing plate arranged in a wind separation box, a coal throwing power mechanism for driving the coal throwing plate to perform a throwing action, and a fan. The dust removal device includes a dust removal box and a sprayer arranged in the dust removal box. The coal fly ash generated after the wind separation by the wind separation device enters the dust removal device for spray dust reduction. In the present invention, the coarse coal on the coal throwing plate is repeatedly thrown into the air and dispersed by the coal throwing power mechanism, and the dispersed coarse coal is wind separated by classification, greatly improving the efficiency of wind coal separation. And the coal fly ash generated by the wind separation is discharged after physical dust removal, avoiding dust pollution to the air.

[0004] The above patent has the following defects in the use process:

[0005] Before the coarse coal material is subjected to coal throwing and dispersion treatment, it is generally gathered together, and the coal inlet is relatively narrow, and there is also a lack of a corresponding auxiliary feeding mechanism. As a result, it is easy to cause feeding blockage during the process of the coarse coal material entering the wind separation box through the coal inlet. Moreover, for some coarse coal material groups with strong aggregation, multiple operations are required to achieve the dispersion effect during the subsequent coal throwing treatment, which is time-consuming and laborious and reduces the working efficiency. Therefore, it is urgent to improve the technology of the wind coal separation device to perfect this equipment.

[0006] Therefore, the utility model proposes a wind coal separation device. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model; obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Embodiment:

[0029] Please refer toFigures 1-4 , a wind coal separation device, including an installation frame 1, a pair of wind separation devices 2 and a dust removal device 3 are installed at the upper end of the installation frame 1, and a pair of wind separation devices 2 are both connected to the dust removal device 3. Feed pipes 4 are installed at the upper ends of a pair of wind separation devices 2. A connecting pipe 5 is provided on the feed pipe 4, and an insertion assembly 6 is installed between the connecting pipe 5 and the feed pipe 4. Rectangular through openings are drilled at the front and rear ends of a pair of connecting pipes 5, and a moving plate 9 that is in close contact with the inner wall thereof is provided inside the rectangular through openings. Elastic telescopic diaphragms 10 are fixedly connected between the upper and lower ends of the moving plate 9 and the inner top and inner bottom of the rectangular through openings. A screening filter plate 11 is fixedly connected between a pair of moving plates 9. A rotary dialing mechanism 12 is installed on the connecting pipe 5, and a magnetic repulsion vibration screening mechanism 13 is installed between the rotary dialing mechanism 12 and the screening filter plate 11.

[0030] During the use of this solution, first cover the connecting pipe 5 on the feed pipe 4, so that the insertion plate 601 in the insertion assembly 6 is inserted into the insertion slot 602. After the insertion plate 601 is inserted and docked with the insertion slot 602, turn the bolt to drive the mounting plate 7 to be connected to the wind separation device 2 to realize the fixed installation of the connecting pipe 5. After the coarse coal material enters the inside of the connecting pipe 5, drive the rotary motor 1202 in the rotary dialing mechanism 12 to work, so that it drives the rotating rod 1201 to rotate. The rotating rod 1201 drives a plurality of dialing pieces 1203 to rotate and disperse the coarse coal material. Then the dispersed coarse coal material falls into the screening filter plate 11. At the same time, the magnet block 1302 on the upper side in the magnetic repulsion vibration screening mechanism 13 rotates synchronously with the rotating rod 1201. When the magnet block 1302 on the upper side rotates 180 degrees and the magnetic end faces downward, it corresponds to the magnet block 1302 on the double-hole sleeve plate 1301, and the two are in a magnetic repulsion state. With the repulsion force, drive the double-hole sleeve plate 1301 and the magnet block 1302 to move downward along the T-shaped rod 1204 and compress the spring 1303. The double-hole sleeve plate 1301 synchronously drives the moving plate 9 and the screening filter plate 11 to move downward with the assistance of the elastic telescopic diaphragm 10. After the magnetic end of the magnet block 1302 on the rotating rod 1201 rotates and resets, after the double-hole sleeve plate 1301 and the screening filter plate 11 lose the action of the magnetic repulsion force, they respectively reset upward under the elastic reset action of the spring 1303 and the elastic telescopic diaphragm 10. Repeatedly like this, the screening filter plate 11 moves up and down under the alternating action of the magnetic repulsion force and the elastic force, and the larger coarse coal material blocks in the dispersed state are vibrated and dispersed again through vibration, so that they are dispersed into multiple small coarse coal material blocks, and then enter the wind separation device 2 through the feed pipe 4, reducing the possibility of feed blockage. At the same time, the dispersed small coarse coal material blocks can complete the work more quickly and conveniently in the subsequent coal throwing process, reducing the coal throwing pressure and improving the work efficiency.

[0031] Furthermore, a pair of plug-in components 6 each include a plug plate 601 fixedly connected to the lower end of the connecting tube 5 , a pair of slots 602 are formed at the upper end of the feed tube 4 , and the plug plate 601 is located in the slots 602 .

[0032] During use of this solution, by setting the plug plate 601 and the slot 602, the connection pipe 5 and the feed pipe 4 are kept precisely docked during the installation and connection process, so as to facilitate subsequent fixed installation.

[0033] Furthermore, the adjacent ends of a pair of connecting pipes 5 are fixedly connected with an L-shaped rod 8, and the lower end of the L-shaped rod 8 is fixedly connected with a mounting plate 7, and the mounting plate 7 is connected to the air selection device 2 by bolts.

[0034] During use, the present invention can drive the mounting plate 7 and the air selection device 2 to be fixed by means of detachable bolts, so as to facilitate the connection pipe 5 to be fixedly installed. Moreover, it can be conveniently disassembled during subsequent inspection and maintenance, thereby improving the convenience of use.

[0035] Furthermore, a pair of rotating dialing mechanisms 12 are rotatably connected to a rotating rod 1201 on the connecting tube 5, and a plurality of dialing plates 1203 are fixedly connected to the outer end of the rotating rod 1201. A pair of T-shaped rods 1204 are fixedly connected to the front and rear ends of the connecting tube 5, and the front ends of the pair of T-shaped rods 1204 located on the front side are fixedly connected to connecting rods 1205. A rotating motor 1202 is installed between the pair of connecting rods 1205, and the output end of the rotating motor 1202 is fixedly connected to the front end of the rotating rod 1201.

[0036] During use of this solution, the rotating motor 1202 drives the rotating rod 1201 to rotate, and the rotating rod 1201 drives the multiple paddles 1203 to rotate, and the coarse coal is spread out and scattered to reduce the aggregation of large pieces of coarse coal and avoid blockage inside the connecting pipe 5 and the feeding pipe 4.

[0037] Furthermore, a pair of magnetic repulsion vibrating screen mechanisms 13 each include a pair of double-hole sleeve plates 1301, which are respectively sleeved on two pairs of T-shaped rods 1204, the upper end of the rotating rod 1201 and the upper end of the pair of double-hole sleeve plates 1301 are fixedly connected with magnet blocks 1302, and the upper ends of the two magnet blocks 1302 in the vertical direction repel each other, the outer ends of the two pairs of T-shaped rods 1204 are sleeved with springs 1303, and the upper and lower ends of the springs 1303 are respectively fixedly connected to the inner top ends of the T-shaped rods 1204 and the upper ends of the double-hole sleeve plates 1301, and the lower ends of the two pairs of T-shaped rods 1204 are fixedly connected with circular baffles 1304.

[0038] During the use of this solution, when the rotating rod 1201 rotates, the magnet block 1302 on the rotating rod 1201 rotates synchronously. When it rotates 180 degrees and the magnetic end faces downward, the magnet block 1302 on the rotating rod 1201 corresponds to the magnet block 1302 on the double-hole sleeve plate 1301, and the two are in a magnetic repulsion state. With the help of the repulsive force, the double-hole sleeve plate 1301 and the magnet block 1302 move downward along the T-shaped rod 1204 and compress the spring 1303. At the same time, the double-hole sleeve plate 1301 drives the moving plate 9 and the screening filter plate 11 to move downward with the assistance of the elastic telescopic diaphragm 10. After the magnetic end of the magnet block 1302 on the rotating rod 1201 rotates back to its original position, when the double-hole sleeve plate 1301 and the screening filter plate 11 lose the effect of the magnetic repulsive force, they respectively return upward under the elastic reset action of the spring 1303 and the elastic telescopic diaphragm 10. This process repeats, causing the screening filter plate 11 to move up and down under the alternating action of magnetic repulsive force and elastic force, and vibrating and dispersing the larger-sized coarse coal blocks during the breakup process again, so that they are dispersed into multiple small coarse coal blocks, reducing the possibility of feed blockage. At the same time, the dispersed small coarse coal blocks can complete the subsequent coal throwing process more quickly and conveniently, reducing the coal throwing pressure and improving work efficiency.

[0039] Further, the two pairs of magnet blocks 1302 are both single-sided magnet blocks, and the upper ends of the two pairs of magnet blocks 1302 are both magnetic ends.

[0040] During the use of this solution, by setting the magnet block 1302 as a single-sided magnet block, with one end having magnetism and the other end not having magnetism, it is possible to reduce the magnetic interference between each other during use and enhance the use effect.

[0041] This solution is an improvement on the coal inlet structure in the patent solution in the background technology. It is written and improved on the basis of the air coal separation device in this solution. Therefore, on this basis, the air separation device 2 and the dust removal device 3 will not be described in detail.

[0042] The wiring diagram of the rotating motor 1202 in this solution belongs to the common knowledge in the field. Its working principle is already known technology, and its model is selected according to actual use. Therefore, the control method and wiring layout of the rotating motor 1202 will not be explained in detail.

[0043] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
