Example Embodiment

[0037] Example 1: A high precision coal mean identification system

[0038] Refer figure 1 This embodiment proposes a high-precision coal gangue identification system, including: base 1, fabric queuing device 100 and coal gangue identification device 200.

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

[0040] The star feeder 102 is mounted on the base 1 by the first support pin 104, and the hopper 101 is disposed on the star feeder 102. The entrance of the hopper 101 is open, and at the bottom thereof is provided with an exit and a mineral inlet of the star type feeder 102. As such, the mineral in the hopper 101 is discharged through the star feeder 102, and the intermittent discharge of the ore is achieved. In the specific implementation, the injection 101 can also be set to a wider download structure to facilitate the decline in the mineral.

[0041] In this embodiment, the coal gangue recognition apparatus 200 inc...

Example Embodiment

[0055] Example 2: A coal mean identification device

[0056] Refer figure 2 , image 3 In this embodiment, a structure of the coal gangue identification apparatus in Example 1 is given.

[0057] In this embodiment, the rotating support frame includes a first rotating shaft 217 that is disposed vertically and a loading bracket that is coupled to the first rotating shaft 217 and rotatably rotatable with the first axis 217. Specifically, in the present embodiment, the first rotating shaft 217 is connected to a first motor 219 for driving its rotation. A axial thrust bearing 218 is also provided at the bottom end of the first shaft 217 to ensure that its rotation is smooth. In this embodiment, the base 1 is also provided with a first cylinder 211, and the first open open setting of the first cylinder 211 is provided. The first rotating shaft 217 is disposed within the first cylindrical 211 by an axial thrust bearing 218, and the loading unit is also located within the first cylindric...

Example Embodiment

[0064] Example 3: One Runar Coal Generation Device

[0065] This example gives another structure of the coal gangue identification device in Example 1.

[0066] Refer Figure 7 to 11 In this embodiment, the rotary support frame includes a second axis 225. The second axis 225 is horizontally mounted on the base 1 and is connected to a second motor 229 for driving the rotation. The second weighing cylinder 227 as the loading unit is disposed on the second shaft 225 and extended in the rotational circumferential direction, and the second weighing cylinder 227 is simultaneously rotated from the second axis 225. The opening direction of the second weighing cylinder 227 is consistent with the direction of rotation of the second shaft 225, and the second weighing cylinder 227 located in the injection region 20a is located in the circulating water tank 201. As described above, as the second shaft 225 is rotated, when the second weighing cylinder 227 enters the circulating water tank 201 a...

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...
