Description

Retractable dust fall chute device

Technical Field

The utility model relates to a XX, specifically speaking relate to a retractable dust fall chute device.

Background

The existing floor coal chute of a coal preparation plant is a fixed chute, a square fixed chute with the periphery sealed is formed by welding iron plates and is installed on a belt head frame, coal flow is unloaded from a belt head and is led out by the fixed chute to fall to the ground, and the height of a coal pile needs to be ensured in order to ensure the storage capacity of a coal storage yard, so that the bottom of the fixed coal chute has higher height from the ground, and the serious dust raising phenomenon in the coal falling process is caused, and the environmental pollution is serious.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a retractable dust fall chute device that can not produce serious raise dust phenomenon at the coal breakage in-process.

In order to solve the technical problem, the utility model discloses a retractable dust fall chute device has square fixed chute, and the upper portion of fixed chute is the coal breakage mouth, the bottom of fixed chute from top to bottom even has the square coal breakage section of thick bamboo of multisection, and the top of each section coal breakage section of thick bamboo is equipped with limiting flange, even has soft wire rope between the limiting flange at adjacent coal breakage section of thick bamboo top, and the coal breakage section of thick bamboo adjacent with fixed chute is adorned in the nozzle department of fixed chute bottom with the limiting flange at its top admittedly, and the bottom nozzle of the coal breakage section of thick bamboo that lies in the top stretches into the upper portion nozzle of the adjacent coal breakage section of thick bamboo that lies in the below, and the internal diameter size of the coal breakage section of thick bamboo top limiting flange that lies in the below is less than the external diameter size; the coal chute is characterized by further comprising a speed reducing motor, two rollers are mounted on an output shaft of the speed reducing motor, lifting steel wire ropes are mounted on the two rollers respectively, lifting rings are mounted on the side walls of the two opposite sides of the coal chute located at the lowest position of the fixed chute respectively, and the tail ends of the two lifting steel wire ropes on the two rollers are connected with the lifting rings on the two side walls of the coal chute respectively.

When the telescopic dust-falling chute device with the structure is used, the speed reducing motor is required to be fixed above the fixed chute, the two rollers on the output shaft are positioned right above the central line of the multi-section square coal chute and correspond to the positions of the hoisting rings at the two sides of the coal chute at the bottom of the fixed chute, when the coal pile is lifted, the speed reducing motor can be controlled to drive the two rollers to rotate, the coal chute at the bottom is firstly lifted to keep the proper height with the coal pile, when the limiting flange at the top of the coal chute at the bottom is contacted with the limiting flange at the adjacent upper coal chute, because the inner diameter of the limiting flange at the top of the coal chute at the bottom is smaller than the outer diameter of the limiting flange at the top of the coal chute at the top, the coal chute at the bottom can jack the coal chute at the top to continuously lift up, namely, the bottom of the coal chute at the bottom can be gradually lifted along with the height increase of the coal pile, therefore, the dust emission phenomenon in the coal falling process can be greatly reduced.

As the improvement of the utility model, the coal dropping device is further provided with two direction-changing pulleys, two hoisting steel wire ropes on the double-roller are respectively wound around the two direction-changing pulleys and then are respectively connected with the hoisting ring on the two side walls of the coal dropping cylinder.

The utility model discloses after well increasing two change pulleys, can be according to place space adjustment gear motor's mounted position, two change pulley's mounted position this moment will be located the square coal breakage section of thick bamboo central line of multisection directly over and corresponding with the position of fixed chute both sides hoisting ring of coal breakage.
