A kind of fast stirring device for mine grouting material

Abstract

The invention discloses a quick stirring device for mine grouting materials, which comprises a mixing drum seat, a supporting base, an upper supporting frame, a feeding hopper, a stirring and mixing assembly and a vibrating feeding assembly. A mixing drum seat is vertically arranged, and the feeding hopper is used to feed grouting materials into the mixing drum seat; an upper support frame is fixed on the side wall of the mixing drum seat, and the vertical The center position in the vertical direction is provided with a relatively rotatable stirring and mixing assembly, which can uniformly mix and stir the grouting material in the mixing cylinder seat, and the upper end surface of the upper support frame is equipped with a drive motor, so The output end of the driving motor is connected and fixed to the stirring and mixing assembly through a reduction gear, and multiple sets of vibrating feeding assemblies are arranged inside the lower end surface of the stirring and mixing drum base, and each vibrating feeding assembly grouts the interior from multiple directions. The material provides auxiliary vibration.

Description

technical field [0001] The invention relates to the technical field of grouting material preparation equipment, in particular to a rapid stirring device for mine grouting material. Background technique [0002] Mine water damage is one of the main hidden dangers that threaten the safety of coal mine production, and it is also an important factor that restricts production activities and sustainable development in many mining areas. At present, with the increase of mining depth, the amount of water gushing out of mines continues to increase, and the discontinuous surfaces such as joints and fissures in the broken rock formations are just water-conducting channels, resulting in a large amount of water gushing in the coal rock body, which poses a serious threat to the safety of coal mines , in order to prevent the threat of water inrush from the confined aquifer of the coal seam floor, grouting water blocking has become one of the effective measures to prevent and control mine w...

Problems solved by technology

However, in the prior art, in the preparation process of grouting materials, because most of the materials are granular, they are easy to form sediment in the mixing tank, resulting in insufficient mixing, and the interior is affected by gravity to form stratification, and most materials cannot be completely grouted. Therefore, it is necessary to propose a fast stirring device for mine grouting materials to solve the above problems
