Detailed description of the invention
In order to understand the present invention in depth, below in conjunction with drawings and the specific embodiments, the present invention is described in detail.
See accompanying drawing 1 and accompanying drawing 2, powdery material drum screen provided by the invention comprises shell 2, cylindric screen cloth, rotating shaft 7, charging aperture 1 and discharging opening 18.
Cylindric screen cloth is arranged in the middle of shell 2.
Rotating shaft 7 is arranged in the center of cylindric screen cloth, make cylindric screen cloth can with rotating shaft 7 for axle rotate.
The end of charging aperture 1 is connected to cylindric screen cloth, and granular material can be rotated with cylindric screen cloth after entering cylindric screen cloth, or is spilt cylindric screen cloth due to gravity.
Discharging opening 18 is arranged at the bottom of shell 2.
The present embodiment is applied to blast-furnace coal powder injection technique, and shell 2 is full-closed structures, so both can prevent coal dust from leaking, and air can be stoped again to enter into shell 2, thus, meet the requirement that blast-furnace coal powder injection technique limits oxygen content.
Wherein, shell 2 bottom can be provided with ash bucket 17, and discharging opening 18 is connected to ash bucket 17 lower end, thus makes discharging more smooth.
Wherein, as a kind of concrete implementation of cylindric screen cloth, cylindric screen cloth can comprise cylindric skeleton 3, screen cloth 4 and press strip 5, and screen cloth 4 is fixed on cylindric skeleton 3 by press strip 5.
Wherein, rotating shaft 7 one end can be connected with motor 12, and under the drive of motor 12, rotating shaft 7 is rotated, thus, realize the electronic rotation of rotating shaft 7.In the present embodiment, motor 12 is fire-proof motor.
Wherein, motor 12 can be connected with deceleration device 11, thus the power output of motor is cut down.In the present embodiment, deceleration device 11 is spindle wheel swinging reducer.
Wherein, in cylindric screen cloth, can bracing or strutting arrangement be arranged at intervals with, thus, the shape of cylindric screen cloth is better fixed.In the present embodiment, bracing or strutting arrangement is support bar 8.
Wherein, cylindric screen cloth can be obliquely installed thus have high-end and low side, and charging aperture 1 end is connected to high-end, and low side is provided with the Ith kind of baffle plate 9, is conducive to like this rolling making full use of of cylindrical sieve axis, is conducive to rolling cylindrical sieve making full use of in axis; The inwall of cylindric screen cloth is provided with multiple IIth kind of baffle plate 6, granular material can be brought to the working part of cylindric screen cloth, be conducive to rolling cylindrical sieve making full use of at circumferencial direction; Both combine can improve the utilization rate of rolling cylindrical sieve, thus improves the sieving capacity of cylinder dress screen cloth.Low side is provided with deslagging chute 15 towards cylindric screen cloth inside, deslagging chute 15 is externally connected to glove compartment 16, thus, the light impurities in granular material is made to be brought in deslagging chute 15 by the IIth kind of baffle plate 6, thus, the light impurities avoided in granular material leaks in discharging opening, effectively removes screening foreign material out.
