Problems solved by technology

This situation is often seen in floods in open-pit mines. Generally, it is necessary to re-purchase water pumps and lay temporary drainage pipes, resulting in a shutdown of production for about half a year and heavy losses.

Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings.

[0012] figure 1 Among them, the stagnant water between the calm flood water surface 1 and the still sand and gravel sedimentation surface 2 is relatively clear. Between the sandstone sedimentation surface 2 and the pit bottom surface 4 is the sandstone carried by the flood, and the mine vertical pump has been buried under the sandstone. In normal times, the water level is generally at the level of 3. Because the bottom plane of the suction bottom valve 7 has a large hole filter screen 6, the sand near the filter screen with the water flow can be sucked away at any time, and this just reaches the effect of removing silt, and drainage is unimpeded.

[0013] Simultaneously buried under the sand and gravel also has the small hole filter screen and its supporting frame 8 of vertical placement. figure 1 Among them, four identical aperture filter screens and their suppor...

Abstract

The invention discloses a mine stand pump capable of being embedded in gravels. The water pump of the mine stand pump capable of being embedded in gravels comprises a permeable small-hole filter screen embedded in the gravels and capable of preventing sand grains and gravels, and a support framework thereof. The small-hole filter screen is directly connected with a water suction hole of a water suction bottom valve or directly connected with a water suction hole of the water pump. The support framework can be a long pipe with holes in the pipe wall, the support framework can be mounted horizontally or vertically, and the support framework upwardly extends to clear water body above a gravel precipitation surface. The mine stand pump capable of being embedded in gravels solves the difficulty that an existing submerged pump or an ordinary centrifugal pump for strip mine would be embedded in the gravels and immediately lose the water drainage ability after the gravels are rushed down by flood especially the flood breaks a dam.

Description

technical field [0001] The invention relates to a mining vertical pump which can be buried under sand. Background technique [0002] When the sand and rocks are washed down by the waves of the flood, especially after a large amount of sand and rocks come in when the flood breaks the dam, the existing submersible pumps or ordinary centrifugal pumps will be buried under the sand and rocks, and immediately lose their drainage capacity. This kind of situation is often seen in floods in open-pit mines. Generally, it is necessary to re-purchase water pumps and lay temporary drainage pipes, resulting in a shutdown of production for about half a year and heavy losses. Contents of the invention [0003] The purpose of the present invention is to provide an improved high-power mining vertical pump for professional sand removal, which can drain water as usual even if it has been buried under sand during the above-mentioned flood. At the same time, when there is no flood, the sand an...
