Fireproof mixing device for mining

Abstract

The invention discloses a fireproof mixing device for mining. The device comprises a grouting pipe and a mixing pipe, wherein the diameter of the mixing pipe is larger than the diameter of the grouting pipe; the mixing pipe communicates with the grouting pipe through a transition pipe; a one-way valve is arranged at the joint of the grouting pipe and the transition pipe; an end cover is arranged on the mixing pipe; a micro motor is arranged on the end cover; the micro motor is provided with a stirring shaft; the stirring shaft is arranged in the mixing pipe; the stirring shaft is provided withstirring blades; and the side surface of the mixing pipe is provided with a feeding pipe and an auxiliary material pipe. The fireproof mixing device has a simple structure and is convenient to use; the mixing pipe is arranged on the grouting pipe, the stirring shaft is arranged in the mixing pipe, and a colloid or a foam solution is fully stirred in the mixing pipe, so that the foam solution or the colloid solution is mixed again, therefore, mixing is uniform, and an optimal foaming and glue injection effect is achieved.

Description

technical field [0001] The invention relates to a mixing device, in particular to a mine fireproof mixing device. Background technique [0002] The implementation of gel injection and foaming at high temperature points in the mine is one of the important control measures taken by our mine in the treatment of high temperature points. During the implementation of foaming and gel injection, grouting pipelines are used, and it is necessary to put The gelling agent is mixed with mud or nitrogen and foaming liquid, and then drilled into the high-temperature point of the goaf to play a role in fire prevention. At present, when foaming or gel injection is carried out, it is necessary to make an additional foamer on the grouting pipeline. Foaming and gel injection cannot be used together with a set of mixing facilities. At the same time, the mixed foam or gel is often mixed unevenly , The disadvantage of poor mixing effect affects the progress and effect of fire prevention and extin...
