Problems solved by technology

[0003] When the existing drainage device drains the water in the open-pit mine water tank, a large amount of impurities at the bottom of the filter screen will accumulate. When the accumulation is too much, manual cleaning is often required, which is time-consuming and laborious. Moreover, the accumulation of impurities will not only increase the operating efficiency of the centrifugal pump. load, and will increase the power consumption of the centrifugal pump, in view of this, a drainage device for open-pit mines is now provided

Abstract

The invention relates to the technical field of drainage devices, and particularly relates to a drainage device for an open pit mine. The drainage device comprises a mounting frame and a centrifugal pump, wherein a floating body is movably arranged in the mounting frame, a fixing box is fixedly arranged at the bottom of the floating body, the top of the fixing box is connected with the input end of the centrifugal pump through a telescopic hose, a groove and two slag discharging grooves are formed in the end face of the bottom of the fixing box, crushing assemblies are arranged in the slag discharging grooves, two water inlet grooves are formed in the groove, filter screens are fixedly arranged in the water inlet grooves, shifting blocks are arranged on the filter screens, and the shifting blocks are slidably connected to the bottom surfaces of the filter screens and are driven by a driving assembly. The driving assembly is arranged so that the automatic cleaning effect on the filter screens can be achieved, the drainage blockage caused by accumulation of a large number of impurities is avoided to a certain extent, the working efficiency of drainage is greatly improved, meanwhile, the load of the centrifugal pump is reduced, the probability of faults of the centrifugal pump is reduced, the electric energy consumed by the centrifugal pump is also reduced, and the device is more environment-friendly.

Description

technical field [0001] The invention relates to the technical field of drainage devices, in particular to a drainage device for open-pit mines. Background technique [0002] In the process of mining ore, groundwater and surface water sources in the rock formation voids will accumulate in the pit. The drainage method of open-pit mines includes centralized drainage at the bottom of open-pit mines, that is, collecting groundwater and other water sources in the rock formation gaps in the water tanks at the bottom of the open-pit mines, and then using centrifugal pumps to transport the water in the water tanks to the water storage tanks on the surface. The filtered water can be used for other purposes, improving the utilization rate of water resources. [0003] When the existing drainage device drains the water in the open-pit mine water tank, a large amount of impurities at the bottom of the filter screen will accumulate. When the accumulation is too much, manual cleaning is of...
