Coal mine central sump sludge cleaning device

Abstract

The invention discloses a coal mine central water sump sludge cleaning device which comprises a shell and a filter cover, wherein a pump with an output end in communication with a pipeline is fixedlyinstalled at the bottom of an inner cavity of the shell, supporting rods are movably connected to the front side and the rear side of the left end of the top of the shell through rotating shafts, anda supporting plate is movably connected to the tops of the supporting rods through rotating shafts. Through arrangement of a sludge pumping pipe, a sleeve, the pipeline and the pump, the pump pumps out sludge through the sludge pumping pipe and the pipeline; through arrangement of the supporting rods, the rotating shafts, first electric telescopic rods and the supporting plate, the purpose of adjusting an inclination angle of the sludge pumping pipe can be achieved, and people can conveniently pump out sludge at different positions; and through arrangement of a second clamping rod, a first clamping rod, a second connecting rod, a second electric telescopic rod, a fourth connecting rod, a third connecting rod, a first connecting rod, a bearing and a clamping plate, the purpose of adjustinga horizontal angle of the sludge pumping pipe can be achieved, and people can conveniently pump out sludge at different positions.

Description

technical field [0001] The invention relates to the technical field of coal mines, in particular to a coal mine central water tank sludge cleaning device. Background technique [0002] The underground mining of coal mines is faced with the threat of various water hazards, which requires the groundwater in each mining area to be drained into the central water tank dug in advance through pipelines, and the floating coal and various industrial wastes also flow into the central water tank along with the water. In the water tank, in order to ensure the safe production of the coal mine, the coal mine safety regulations stipulate that before the rainy season comes every year, the sludge accumulated in the central water tank must be thoroughly excavated. However, the existing dredging methods are manual cleaning, which not only increases people The amount of labor, but also reduces the dredging efficiency, for this reason, we propose a coal mine central water tank sludge cleaning de...
