Description

TECHNICAL FIELD

[0002] In coal mining operations, underground accumulated water needs to be lifted to the ground drainage pool for treatment through a pipeline. Since the discharged accumulated water usually contains a large amount of fine coal mine impurities, in order to achieve solid-liquid separation, the conventional method is to let the accumulated water stand and deposit in the drainage pool before being discharged. However, this treatment method has the following disadvantages: after the drainage is completed, a large amount of coal mine impurities will be deposited in the middle and bottom of the inner wall of the drainage pool, which needs to be manually or separately removed by special equipment, thereby increasing the operation steps, consuming a large amount of manpower and material resources, and increasing the overall use cost.

[0049] The working principle of the present application is as follows:

[0050] The water in the coal mine underground water well is lifted to the inside of the drainage tank 1 on the ground through the pipeline, and the water flows into the inside of the drainage tank 1 from the left side. Since there are a lot of coal ash mixed in the water, when the water flows into the inside of the drainage tank 1, a lot of coal ash is deposited on the upper end of the four push plates 21, and a part of the coal ash is directly deposited on the bottom surface of the drainage tank 1.

[0051] When it is needed to discharge the water inside the drainage pool 1, the control motor 27 is opened, the motor 27 drives the third rotating rod 28 to rotate, the third rotating rod 28 drives the hollow pipe 12 to rotate, at the same time, the third rotating rod 28 drives the transmission rod 30 to rotate through the meshing of the driving bevel gear 29 and the driven bevel gear 31, the transmission rod 30 drives the first rotating rod 17 to rotate through the driving belt 34, the first rotating rod 17 drives the two second rotating rods 5 to rotate simultaneously through the synchronous belt 36. When the first rotating rod 17 rotates, it drives the four eccentric wheels 19 and a ring of blades 18 to rotate simultaneously, the eccentric wheels 19 drive the sliding rods 20 to reciprocatingly lift and fall when rotating, the sliding rods 20 drive the four push plates 21 to reciprocatingly lift and fall, the reciprocating lift and fall strokes of the four push plates 21 are different, so that the cinder on the upper end of the first push plate 21 on the left side slides to the upper end of the second push plate 21 on the left side, the cinder on the upper end of the second push plate 21 on the left side slides to the upper end of the third push plate 21 on the left side, the cinder on the upper end of the third push plate 21 on the left side slides to the upper end of the fourth push plate 21 on the left side, and the cinder on the upper end of the fourth push plate 21 on the left side slides to the innermost right end of the drainage pool 1. The scraper 7 is driven by the second rotating rod 5 to reciprocate from left to right, so as to scrape and send the cinder deposited at the bottom of the drainage pool 1 to the innermost right end of the drainage pool 1. Since the first rotating rod 17 drives the blades 18 to rotate simultaneously, the blades 18 in rotation mix the water and the cinder at the innermost right side of the drainage pool 1 evenly.

[0052] The water pump 8 is opened, the mixed water and cinder at the innermost right side of the drainage pool 1 are all pumped into the innermost right end of the feeding hopper 25 through the conveying pipe 9, the water and cinder mixture in the innermost right end of the feeding hopper 25 enters into the hollow pipe 12 through the feeding pipe and the feeding cylinder 13, and is input into the filter cylinder 11 from the water outlet hole 14 at the lower end of the hollow pipe 12. The water and cinder mixture in the filter cylinder 11 is lifted upwards by the action of the spiral plate 15, in the process of lifting upwards, the water flows into the treatment tank 10 after being filtered through the filter holes on the filter cylinder 11, while the cinder is continuously lifted by the spiral plate 15 and finally conveyed into the connecting channel 38 from the discharge port 26, and the filtered water in the treatment tank 10 is discharged outward from the drain pipe 24.

[0053] When the cinder enters into the connecting channel 38, the hollow tube 12 drives the feeding cylinder 13 to rotate synchronously, and the feeding cylinder 13 drives the push block 47 to rotate synchronously, when the push block 47 contacts with the horizontal section of the L-shaped rod 46, the L-shaped rod 46 is pushed to move away from the hollow tube 12, and the L-shaped rod 46 drives the extrusion block 41 to move away from the hollow tube 12, and the spring 45 is compressed. When the push block 47 passes through the horizontal section of the L-shaped rod 46, the extrusion block 41 and the L-shaped rod 46 return to the initial position under the rebound force of the spring 45, so that the reciprocating sliding of the extrusion block 41 is realized. The reciprocating sliding of the extrusion block 41 can reciprocally extrude the cinder entering into the connecting channel 38, and the water in the cinder can be squeezed out through the reciprocating extrusion of the extrusion block 41, and enters into the treatment tank 10 through the through hole in the bottom plate of the connecting channel 38. The extruded cinder is discharged outward through the discharge pipe 39.

[0054] During the extrusion of the extrusion block 41, the extrusion rod 42 and the extrusion sheet 44 synchronously participate in the work, the extrusion rod 42 is inserted into the cinder along with the sliding of the extrusion block 41, and plays a role of dispersing the clumped impurities. The extrusion sheet 44 continues to extrude the cinder after contacting with the cinder, and the water in the cinder is squeezed out to the maximum extent through the multi-layer extrusion, so that the dehydration effect is improved.
