Abstract
The utility model relates to a coal pillar pipeline conveying chain type feeding and feeding-back device which can pour a coal pillar into a pipeline by means of a feeding chain and pressure of a power pump, and meanwhile can recycle the coal pillar and convey the coal pillar back to a bin from the pipeline. The coal pillar pipeline conveying chain type feeding and feeding-back device comprises a feeding system, a feeding-back system, the feeding chain, an air evacuation valve and a buffer tank. The feeding system comprises a power pump, the buffer tank, a feeding pipe and a stop valve, and the feeding-back system comprises the stop valve, a feeding-back pipe, a metal net conveying belt, a water fender, a water storage pond and a coal pillar bin.
Description
Affiliated technical field
The utility model relates to a kind of coal column ducting chain type and advances feed back equipment, can be widely used in the ducting coal column engineering item, uses as the feed back equipment that advances of ducting coal column, belongs to ducting coal column equipment technical field.
Background technology
Before the utility model is made; The charging of ducting coal column is to accomplish charging through alternately controlling the valve that is arranged on the rhombus pipeline; The feed back equipment of ducting coal column also is to arrange separately, thisly advances the feed back mode and needs floor area big, complex process; And advance feed back and have some setbacks, influenced the normal safe operation of ducting coal column.
Summary of the invention
Advance the feed back problem for what improve the ducting coal column, improve existing coal column pipeline and advance the feed back mode, simplify technological process; Reduce floor area; Guarantee the normal safe operation of ducting coal column, the utility model provides a kind of coal column ducting chain type to advance feed back equipment, and it is simple that this coal column ducting chain type is advanced the feed back device structure; Easy for installation, it is effective that coal column advances feed back.
The utility model solves the technical scheme that its technical matters adopted: it is made up of feed system, material return system, feeding chain, blow off valve and expansion tank; Wherein feed system is to be made up of kinetic pump, expansion tank, feed pipe and shutoff valve, and material return system is to be made up of shutoff valve, feed back pipe, metal gauze transport tape, manger, tank and coal column storehouse.
The beneficial effect of the utility model is that the coal column that can be used for any ducting coal column engineering item advances feed back equipment to be used, thereby has reduced floor area, has simplified technological process, has guaranteed the normal safe operation of ducting coal column.
