The left view (charging aperture is not shown among the figure) of the granular material rotary screen that Fig. 2 provides for the embodiment of the invention.
The specific embodiment
In order to understand the present invention in depth, the present invention is elaborated below in conjunction with accompanying drawing and specific embodiment.
Referring to accompanying drawing 1 and accompanying drawing 2, granular material rotary 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 the shell 2.
Rotating shaft 7 is arranged in the center of cylindric screen cloth, makes that cylindric screen cloth can serve as that axle rotates with rotating shaft 7.
The end of charging aperture 1 is connected in cylindric screen cloth, makes granular material after getting into cylindric screen cloth, can rotate with cylindric screen cloth, perhaps because gravity is spilt cylindric screen cloth.
Discharging opening 18 is arranged at the bottom of shell 2.
Present embodiment is applied to blast-furnace coal powder injection technology, and shell 2 is full-closed structures, so both can prevent that coal dust from leaking, and can stop air to enter into shell 2 again, thereby, satisfy of the requirement of blast-furnace coal powder injection technology to the oxygen content restriction.
Wherein, shell 2 bottoms can be provided with ash bucket 17, and discharging opening 18 is connected in ash bucket 17 lower ends, thereby 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 the cylindric skeleton 3 by press strip 5.
Wherein, rotating shaft 7 one ends can be connected with motor 12, and under the drive of motor 12, rotating shaft 7 is rotated, thereby, realize the electronic rotation of rotating shaft 7.In the present embodiment, motor 12 is a fire-proof motor.
Wherein, can be connected with deceleration device 11 on the motor 12, thereby the power output of motor is cut down.In the present embodiment, deceleration device 11 is a spindle wheel swinging reducer.
Wherein, can be arranged at intervals with bracing or strutting arrangement in the cylindric screen cloth, thereby, make the shape of cylindric screen cloth obtain better fixing.In the present embodiment, bracing or strutting arrangement is a support bar 8.
Wherein, thereby cylindric screen cloth can be obliquely installed and has high-end and low side, and charging aperture 1 end is connected in high-end, and low side is provided with I kind baffle plate 9, helps axial the making full use of of cylinder shape screen cloth like this, helps cylinder shape screen cloth in axial making full use of; The inwall of cylindric screen cloth is provided with a plurality of II kind baffle plates 6, can granular material be brought to the working part of cylindric screen cloth, helps cylinder shape screen cloth making full use of at circumferencial direction; Both combinations can improve the utilization rate of cylinder shape screen cloth, thereby improve 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; Thereby, the light impurities in the granular material is brought in the deslagging chute 15 through II kind baffle plate 6, thereby; Avoid the light impurities in the granular material to leak in the discharging opening, removed the foreign material that screening is come out effectively.
Wherein, II kind baffle plate 6 can have the space between direction high-end near cylindric screen cloth and cylindric screen cloth, thereby the unlikely granular material that influences is spilt cylindric screen cloth under the gravity effect.
