Description

Technical Field

[0001] The present invention relates to the technical field of ecological restoration, and more specifically, to a drainage water treatment system for mine ecological restoration. Background Art

[0002] Drainage water refers to the drainage water that gushes out from the coal seam during the coal mining process. There are many sources of drainage water, such as surface infiltration water and groundwater water generated during mine mining. It is polluted by sand and mud particles, dust, dissolved salts, acids and alkalis, coal particles, oils, etc., which affect the ecology of artificial wetlands and are very polluting. Mine drainage water has always been regarded as a water hazard to be prevented and controlled.

[0003] There are fine rocks in the drainage water. Directly passing the drainage water containing fine rocks through the purification and treatment equipment will cause damage to the purification and treatment equipment, reduce the service life of the purification and treatment equipment, and increase the subsequent maintenance cost. Therefore, the drainage water needs to be cleaned out of the fine rocks before preventive treatment. In the prior art, the drainage water is usually passed through a filter plate to filter the rocks. However, as time goes by, rocks and silt accumulate on the filter plate, causing the filter plate to be blocked. The filter plate needs to be cleaned in time. The cleaning process requires stopping the delivery of the drainage water, and online cleaning cannot be achieved, which seriously affects work efficiency. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a drainage water treatment system for mine ecological restoration, which transports drainage water to a separation box through a feed pipe, and at the same time controls the rotation of the conveying component, so that the drainage water and most of the silt are discharged through the second filter plate, and the finely crushed rock is transported to the discharge port along the first filter plate and falls into the recovery box to be collected, thereby realizing the automatic online circulation separation of the finely crushed rock and improving the separation efficiency of the finely crushed rock in the drainage water.

When the first filter plate 8 on the conveying assembly 5 is transmitted through the corrugated guide plate 16, the corresponding ball head 14 slides along the corrugated guide plate 16, and cooperates with the return spring 17 to make the scraper 12 and the first inclined surface 13 on the corresponding pushing assembly 10 slide back and forth along the corresponding first filter plate 8, and push the crushed rocks on the corresponding first filter plate 8 to the discharge assembly 40 through the discharge port 19.

[0052] When the corresponding first filter plate 8 moves to the top of the discharge assembly 40 and presses the two gear rods 47, the corresponding first filter plate 8 descends, driving the discharge assembly 40 to descend synchronously, and the tension spring 60 is stretched. When the guide ball 48 moves to the second inclined surface 51, the two gear rods 47 are pulled away from each other under the elastic reset force of the corresponding connecting spring 49 until they are separated from the first filter plate 8. The first filter plate 8 is smoothly separated from the avoidance groove 44, and the discharge assembly 40 is driven to rise and reset under the elastic reset force of the tension spring 60, thereby realizing the reciprocating lifting of the discharge assembly 40. In this process, the cam 56 is driven to rotate back and forth through the meshing cooperation of the gear 57 and the tooth plate 58, thereby driving the discharge plate 53 to swing, further improving the efficiency of crushed stone discharge.
