Detailed description of the invention
Below provide specific embodiment of the utility model, it should be noted that the utility model is not limited to following specific embodiment, all equivalents done on technical scheme basis all fall into protection domain of the present utility model.
Embodiment:
Defer to technique scheme, as shown in Figure 1 to Figure 3, the present embodiment provides a kind of sorting unit for the sorting of low speed coal mill steel ball, comprise airtight housing 1, described housing 1 is arranged on buffering stand 2, and side, housing 1 top is provided with charging aperture 3, and housing 1 outside is provided with vibration source 4;
Housing 1 inside is tiltedly installed with multilayer steel ball separating sieve 5 from top to bottom successively, steel ball separating sieve 5 near one end of charging aperture 3 higher than steel ball separating sieve 5 one end away from charging aperture 3, the one end away from charging aperture 3 is provided with steel ball feeder 6 for every layer of steel ball separating sieve 5;
Steel ball separating sieve 5 is provided with the coal powder collection plate 7 parallel with steel ball separating sieve 5 below, and bottom housing 1, the side of charging aperture 3 is provided with coal powder collection mouth 8, coal dust is from coal powder collection plate 7 landing to coal powder collection mouth 8.
Airtight housing 1 prevents the coal dust escape airborne dust when sorting unit works on steel ball.
Vibration source 4 turns to contrary vibrating motor to provide exciting force for two.
Further, buffering stand 2 is provided with road wheel 9.
Further, buffering stand 2 is connected with hauling machine 10, hauling machine 10 adopts battery truck.
Further, charging aperture 3 is connected with feed riser machine 11, feed riser machine 11 adopts width to be the drag conveyor of 500mm, carries road wheel.
Further, steel ball separating sieve 5 is 5 ° with the inclination angle on ground, prevents steel ball from piling up on sorting layer, also prevents coal dust from entering in steel ball feeder 6.
Further, multilayer steel ball separating sieve 5 is four layers, is followed successively by 60 millimeters of separating sieve 5-1,50 millimeters of separating sieve 5-2,40 millimeters of separating sieve 5-3 from top to bottom and is less than 40 millimeters of separating sieve 5-4.
Further, the sieve aperture on 60 millimeters of separating sieve 5-1,50 millimeters of separating sieve 5-2 and 40 millimeter of separating sieve 5-3 is bar hole, and the described sieve aperture being less than 40 millimeters of separating sieve 5-4 is circular port.The cooperation of bar hole and circular port can well by steel ball and coal dust separately, and unlikely coal dust enters in steel ball feeder 6 together along with steel ball again.
The course of work of the present utility model is as described below:
Buffering stand 2 and feed riser machine 11 draw to Active workings by hauling machine 10, pack up the road wheel 9 of buffering stand 2, are directly supported on the ground by buffering stand 2, Vibration on Start-up source 4.To treat in coal-grinding machine barrel that the steel ball dump truck of sorting is transported to feed riser machine 11 lower end, steel ball delivers to the charging aperture 3 of housing 1 upper end by feed riser machine 11, enters in housing 1.
The steel ball that diameter is greater than 60mm is stayed on 60 millimeters of separating sieve 5-1, and enter steel ball feeder 6 along 60 millimeters of separating sieve 5-1, the steel ball that diameter is greater than 60mm is collected separately, diameter is less than the steel ball of 60mm and other foreign material (coal dust etc.) enter 50 millimeters of separating sieve 5-2 through 60 millimeters of separating sieve 5-1, pushes away according to part of speech.
Coal dust falls into coal powder collection plate 7 from being less than 40 millimeters of separating sieve 5-4, and due to the inclination of coal powder collection plate 7, under the effect of vibration of vibration source 4, coal dust slips into coal powder collection mouth 8 along coal powder collection plate 7 and collects separately.
