Embodiment 1

[0037] Embodiment 1: A high-precision gangue identification system

[0038] refer to figure 1 , this embodiment proposes a high-precision gangue identification system, including: a base 1 , a cloth queuing device 100 and a gangue identification device 200 .

[0039] The fabric queuing device 100 includes: a hopper 101 , a star feeder 102 and a first support foot 104 .

[0040] The star feeder 102 is installed on the base 1 through the first supporting foot 104 , and the feeding hopper 101 is arranged on the star feeder 102 . The top of the feeding hopper 101 is open, and the bottom is provided with a monolithic material outlet and communicated with the mineral material inlet of the star feeder 102 . In this way, the mineral material fed into the hopper 101 is discharged through the star feeder 102, realizing the intermittent and uniform discharge of the mineral material. During specific implementation, the feeding hopper 101 can also be set as an upper-wide loading structur...

Embodiment 2

[0055] Embodiment 2: A coal gangue identification device

[0056] refer to figure 2 , image 3 , this embodiment provides a structure of the gangue identification device in Embodiment 1.

[0057] In this embodiment, the rotating support frame includes a vertically arranged first rotating shaft 217 and a loading bracket connected to the first rotating shaft 217 and rotating synchronously with the first rotating shaft 217 . Specifically, in this embodiment, the first rotating shaft 217 is connected with a first motor 219 for driving its rotation. The bottom end of the first rotating shaft 217 is also provided with an axial thrust bearing 218 to ensure its stable rotation. In this embodiment, a first cylinder 211 is further provided on the base 1 , and the top of the first cylinder 211 is open. The first rotating shaft 217 is disposed in the first cylinder 211 through an axial thrust bearing 218 , and the loading units are also located in the first cylinder 211 . In this wa...

Embodiment 3

[0064] Embodiment 3: A kind of wheel-type gangue identification device

[0065] This embodiment provides another structure of the gangue identification device in Embodiment 1.

[0066] refer to Figure 7 to Figure 11 , in this embodiment, the rotating support frame includes: a second rotating shaft 225 . The second rotating shaft 225 is horizontally installed on the base 1 and is connected with a second motor 229 for driving it to rotate. The second weighing cylinder 227 as a loading unit is arranged on the second rotating shaft 225 and is evenly distributed along its rotating circumferential direction, and the second weighing cylinder 227 and the second rotating shaft 225 rotate synchronously. The opening direction of the second weighing cylinder 227 is consistent with the rotation direction of the second rotating shaft 225 , and the second weighing cylinder 227 located in the water injection area 20 a is located in the circulating water tank 201 . In this way, with the ro...

Abstract

The invention provides a coal and gangue separation device. The coal and gangue separation device comprises a first supporting seat, a guide part and a plurality of stock bins, wherein the guide partis hinged to the first supporting seat and rotates in the vertical direction; and inlets of the plurality of stock bins are sequentially distributed on the rotating track of the movable end of the guide part. The coal and gangue separation device has the advantages that high-pressure airflow of high-pressure spray nozzles acts on a screen bar driving mechanism instead of directly acting on materials; the screen bar driving mechanism drives cantilever screen bars to rotate; directional discharging of mineral aggregates is achieved, so that gangue can accurately enter a gangue collecting box; and clean coal can accurately enter a clean coal collecting box.

Description

technical field [0001] The invention relates to the field of coal and gangue separation equipment, in particular to a coal and gangue separation device. Background technique [0002] Coal and gangue identification and coal and gangue separation are indispensable in raw coal and gangue removal. The separation of coal and gangue in the traditional photoelectric separation device is carried out by airflow injection, and there is uncertainty in the confinement of the airflow, resulting in scattered thrust, and the separation of coal and gangue of materials is difficult to control the strength of the airflow. Contents of the invention [0003] In order to solve the above-mentioned defects of separating coal and gangue by air flow in the prior art, the present invention proposes a coal and gangue separation device. [0004] The present invention adopts following technical scheme: [0005] A coal and gangue separation device is characterized in that it comprises: a first suppor...
