Abstract

The invention discloses a dewatering device and method for grouting filling in mining industry. The device comprises an all-metal casing, a grouting flattening plate, a motor connecting rod, a thrusthydraulic oil cylinder, a centrifugal water suction pump, a protective top plate and a top plate suspension hook, wherein the grouting press plate is arranged in the all-metal casing; the centrifugalwater suction pump is mounted above a water suction pipe; the protective top plate is mounted above the centrifugal water suction pump; the top plate suspension hook is mounted above the protective top plate; a water storage tank is mounted below the top plate suspension hook; a water flow outlet is formed in one side of the water storage tank; a water outlet control valve is mounted above the water flow outlet; an oil cylinder pressurizing pump is mounted on one side of the thrust hydraulic oil cylinder; operation control buttons are mounted on the outer side of the all-metal casing. The dewatering device has the following beneficial effects: filling surface water after grouting can be removed by suction, the filling surface after suction can be flattened, and the filling effect is guaranteed.

Description

technical field [0001] The invention relates to the field of mining equipment, and the invention relates to a mining grouting filling dehydration device and method. Background technique [0002] Grouting is divided into ceramic craft grouting and construction engineering grouting. Ceramic technology grouting is a process of injecting prepared mud into ceramic production. Construction engineering is a method of injecting some curable grout into the cracks or pores of rock foundations with appropriate methods, and improving its physical and mechanical properties by means of replacement, filling, extrusion, etc. General mining underground mining grouting filling project adopts a sealing wall to close the filling area at the mouth of the filling area. A grouting input pipe passes through the wall from outside the filling area and enters the filling area and is located on the top of the filling area. When transported into the filling area, since the upper layer of the slurry is...
