[0002] During the coal mining process, due to mine water inrush, water used for cutting coal seams, water used for underground dust removal, etc., a large amount of underground coal slime water will be generated, which will accumulate at the bottom of the sump for a long time and form accumulated coal slime. This not only reduces the effective volume of the sump, but also once the accumulation amount exceeds the threshold, a large amount of coal slime will enter the water distribution small well of the main drainage system, and the contained coal slime particles will wear the drainage system. In serious cases, it may block the suction port of the main drainage pump, endangering production safety. The traditional dehydration device has a high vibration intensity, the sieve plate is easily damaged, and its dehydration ability for high water content coal slime is limited. The free water content of the separated coal body is still relatively high, and the pressure in the transportation and lifting links is relatively large. The probability of safety accidents caused by transporting and lifting water coal is relatively high. Content of the Utility Model

[0020] The following further describes the present utility model with reference to the drawings.

[0021] As shown in Figures 1-6As shown in the figure, a mine vibration dehydration device includes a base 1 and a vibrating screen 2. The base 1 and the vibrating screen 2 are connected by shock absorbers 3 to reduce the vibration amplitude of the base 1 and improve the stability of the device. The vibrating screen 2 includes two oppositely arranged side plates 4. A mounting plate 5 is fixedly connected between the tops of the side plates 4. A vibrating table 6 is fixedly connected to the mounting plate 5. Two vibrating shafts 7 are rotatably connected to the vibrating table 6. An eccentric block 8 is fixedly connected to each vibrating shaft 7. Two driving motors 9 are fixedly connected to the outside of the side plates 4. Each vibrating shaft 7 corresponds to one driving motor 9. The output end of the driving motor 9 is softly connected to the vibrating shaft 7. The driving motor 9 drives the eccentric block 8 to rotate, so that the vibrating table 6 vibrates, serving as the vibration source of the device. The two driving motors 9 can operate independently or simultaneously, so as to adjust the vibration intensity of the device and dehydrate slime with different water contents.

[0022] Two sieve plates 10 are arranged inside the side plate 4. The two sieve plates 10 are arranged in layers. The sieve plate 10 includes a sieve mesh 12 and a fixing mechanism 11. The two ends of the sieve mesh 12 are fixedly connected with horizontally arranged limiting plates 13. Limiting holes 17 are opened at both ends of the limiting plate 13. A rubber sleeve 18 is arranged in the limiting hole 17. The rubber sleeve 18 can protect the limiting rod 15 and avoid causing a large impact on the limiting rod 15 during vibration. Four fixing mechanisms 11 are provided, corresponding to the four limiting holes 17 respectively. The fixing mechanism 11 includes a fixing frame 14. A limiting rod 15 is vertically arranged on the fixing frame 14. The limiting plate 13 is slidably connected with the limiting rod 15. The limiting rod 15 passes through the corresponding limiting hole 17. The aperture of the rubber sleeve 18 is larger than the diameter of the limiting rod 15. The sieve mesh 12 can vibrate in both horizontal and vertical directions. A spring 16 is arranged between the top of the limiting plate 13 and the top of the fixing frame 14. A spring 16 is also arranged between the bottom of the limiting plate 13 and the bottom of the fixing frame 14. The spring 16 is sleeved on the limiting rod 15. The spring 16 can play a buffering role and make the sieve plate 10 vibrate stably. A vertically arranged adjusting hole is opened on the side plate 4. An adjusting screw rod 19 corresponding to the adjusting hole is fixedly connected to the fixing frame 14. The adjusting screw rod 19 passes through the adjusting hole and is locked and fixed by a nut.

Through the double driving motors 9, the vibration frequency is adjusted to adjust the processing capacity and dehydration efficiency, cope with the impact on the dehydration device caused by uneven water and coal volume, relieve the transportation pressure, and reduce the frequency of pull bin accidents caused by water pressure.
