Movable pebble coal sealing collector

Abstract

The invention relates to a movable pebble coal sealing collector, which comprises a slideway plate and a casing, a left barrier strip and a right barrier strip are arranged on the slideway plate, a block is provided at back of a vertical plate and at the front of the slideway plate, a car-covering block is provided at inner side of the barrier strip, an aslant downward feed inlet is provided over the casing, a downward discharge hatch with a circular table surface shape is provided at the lower part of the casing, a bottom plate is hinged beside the discharge hatch, a truncated cone-shaped wedge cooperated with the discharge hatch with a circular table surface shape is provided on the bottom plate, the walking wheels are provided under the bottom plate, a plugboard against the lower part of the above block is provided at the front of the body of the casing, an inspection port is provided on the body of the casing, a fork truck lug is arranged at the back of the body of the casing, a connecting ring of the feed inlet is connected against an upper connecting ring, and an elastic sealing ring in a circular ring shape is embedded at the lower side surface of the upper connecting ring. According to the invention, the pebble coal can be freely slipped to an enclosed casing without obstacle under the condition of constant pressure, coal dust can not be discharged, the working environment is clean, the health of the operators can be ensured, after the casing is filled by the pebble coal, a fork truck is used for transporting the casing filled with the pebble coal, the labor intensity is low, and the operating efficiency is high.

Description

technical field [0001] The invention relates to a pebble coal collecting device used in a pebble coal discharge system, in particular to a pebble coal sealing collector. Background technique [0002] During the coal grinding operation of the medium-speed coal mill in the pulverizing system of thermal power plants, there are always some granular materials that are difficult to grind, and these granular materials are called pebble coal. During the coal grinding process of the medium-speed coal mill, the pebble coal can be separated and enter the pebble cinder box at the lower side of the medium-speed coal pulverizer. The coal discharge port is connected with a discharge valve, oblique to the effective diameter and discharge angle of the pebble coal discharge port, to ensure that the pebble coal can slide and discharge freely, and the discharge valve is used to keep the medium-speed coal mill closed when not discharging During the operation of the medium-speed coal mill, the d...

AI Technical Summary

Problems solved by technology

Using an open temporary storage tank to store the pebble coal discharged from the discharge port will cause dust to fly on the site, resulting in a bad working environment and greatly endangering the health of the staff; in addition, manually removing the pebble coal from the temporary storage tank Loading it on a transport vehicle is labor-intensive and the work efficiency is very low

[0008] In the prior art, there is no better temporary storage device for discharging pebble coal from the oblique discharge port of a medium-speed coal mill in a dress with a good working environment, low labor intensity and high work efficiency.
