Description
Technical field
The utility model relates to a kind of coal dust and transports screening system.
Background technology
In various enterprises, the application of raw coal is all compared extensively.Generally all be that former coal dust is delivered to vibratory sieve through screening through convey coal pipe, the product that granule is qualified gets into belt conveyor, and oarse-grained rough coal is sent to and carries out fragmentation in the disintegrating machine, the circulation screening of broken back.This mode is sieved the thickness coal dust to a certain extent.Also has the following disadvantages: higher speed vibrating screen, fine coal particles is not too late to roll off the opinions from the shaker was driven by crude coal into the crusher, that generative force coarse coal coal easy to sneak into the crusher, the crusher increased load, likely to cause burn-crusher.Frequent maintenance or broken disintegrating machine not only increase cost, and have wasted the time, and production efficiency is low.
Summary of the invention
The purpose of the utility model just is to overcome above-mentioned deficiency provides a kind of coal dust to transport system.
The purpose of the utility model can realize through following technical scheme:
A kind of coal dust transports system, comprises convey coal pipe, screening plant is set below the convey coal pipe; Belt conveyor is set below the screening plant, and screening plant also leads in the shredder hopper through discharge nozzle, and said screening plant is a rotary screen; Comprise the housing that is obliquely installed, in housing, be provided with the screen cloth tube with same angle of inclination, the end that convey coal pipe passes housing extend in the screen cloth tube; Be provided with bearing between convey coal pipe and the screen cloth tube end cap, the center of another end cap of screen cloth tube is provided with rotating shaft, and the output shaft fixed connection of housing end plug and motor is stretched out in rotating shaft; Be provided with bearing between rotating shaft and the housing end plug, the screen cloth tube is little mesh screen cloth near the part of convey coal pipe, is big mesh screen cloth in the part near motor side; Little mesh screen cloth corresponding shell is provided with discharging opening, and discharging opening is provided with hopper, is provided with belt conveyor below the hopper; Big mesh screen cloth corresponding shell is provided with discharging opening; In discharging opening, be provided with the coarse fodder bucket, the coarse fodder bucket is connected with pulverizer through pipeline, and the pulverizer discharging opening is communicated on the convey coal pipe through defeated material hoisting mechanism.
Above-mentioned coal dust transports system, and said screen cloth tube is made up of screen bed base and the screen cloth that is enclosed within on the screen bed base, and screen bed base is to be made up of many that are fixed between the two end cap bracing frames that are parallel to each other.
Above-mentioned coal dust transports system; The bottom end cover of said screen cloth tube is to be the steel column that is provided with radially of center with the rotating shaft and to be that the annular cylinder muscle in the center of circle constitutes with the rotating shaft by many; One end of steel column is fixed on that the other end is fixed on the annular cylinder muscle in the rotating shaft; One end of support column is fixed on the annular cylinder muscle, and the other end is fixed on the plate of screen cloth tube upper end cover plate on week.
Adopt technique scheme, the utility model has following advantage: because screening plant is a rotary screen, the screen cloth tube can rotate in housing; Material carries out in the screen cloth tube like this; Under constantly rolling, coal dust is separated, housing and screen cloth tube are to be obliquely installed on the other hand; Material tumbles from sieve screen apertures in the rotating process not stopping under the effect of its gravity.The thickness of its coal dust is separated thoroughly, thereby guarantees not contain duff in the rough coal, guarantees normally carrying out smoothly of postorder shattering process.The utility model is simple in structure, and is easy to use, and effect is remarkable.The screening that is fit to coal dust is transported.
