Apparatus for cleaning and transporting coal-mine water sump slurry

Abstract

The invention relates to a water coal mud clear transforming device used in the mine well which is set with the center pump room, the inner / out center water store and bypass parallel with the mine lane. The lower of the inner / out center water store are opened with the left / right drainage lane and dog hole. The left and right drainage lanes are connected with the bypass, the drainage hole is opened at the bottom of the water cabin bottom; the output of the drainage hole is fixed with the upper / lower steel frame between which is fixed with the pressure releasing buffer valve. Under it has the coal mud dewater treating vehicle. The vehicle includes the condensing box, the slag pump, the hydraulic pressure station, the filter press, the spiral conveyer and the tank car. The output of the slag pump is connected with the inlet of the filter press. The filter press is controlled by the hydraulic pressure station which the output is fixed with the spiral conveyer, under which is the tank car. It can improve the safety ratio and water resistance ability.

Description

technical field [0001] The invention relates to a cleaning and transportation device for coal slime in an underground water bin of a coal mine. Background technique [0002] As one of the four major disasters in coal mines (water, fire, gas, and coal dust), mine flooding in coal mines is crucial to the safety of coal mines. Therefore, in general mine design, each mine and each mining of each mine Levels are all selected near the bottom of the well or at a suitable location in the central area, and are designed with two water tanks (or inner and outer) in the center and a central pump room. The two central water tanks are connected with the central pump house and used alternately, that is, one is used and the other is used for clearing and digging. Clearing and digging water tanks has always been a major problem in coal mine production organization and management. The sediments are thick, sticky, and thin. It sounds very difficult and annoying. In the past, many people hav...

Problems solved by technology

[0003] Manual dredging tank truck transportation is the most primitive way of dredging. People use shovels or small barrels to load coal slime into tank trucks. In addition to sticking coal slime, it is difficult to operate and labor-intensive. It is also impossible to transport tank trucks through slopes. When the tanker is full, it can only be filled with one-half or one-third, otherwise the mud will flow out once it is lifted and transported on a slope, and it is often because it is not easy to control the loading volume, and the tanker itself is not well sealed and leaks slurry, so As a result, every time a water tank is dug, it will cause serious pollution along the transportation, which not only brings difficulties to pedestrians, but also seriously affects the normal use of transportation safety facilities (tank stalls).

Since each tanker cannot be fully filled, half-load transportation is formed, which not only occupies more tankers, but also causes great waste of energy consumption and labor

There are also tank trucks that once transport coal slime, causing serious pollution, and tank trucks participate in the transportation turnover of the whole mine, and then load coal cinders, the coal cinders will stick to the inside of the tank trucks, commonly known as "big tank bottoms", which are extremely difficult to remove. The volume of the tank car becomes smaller and the load is empty. Therefore, it is said that using a tank car to transport mud for clearing the water tank will cause endless troubles, which will bring great pressure to the mine car transportation, and it is also a great waste
