Embodiment 1

[0043] Embodiment 1: A high-precision gangue identification system

[0044] 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 .

[0045] The fabric queuing device 100 includes: a hopper 101 , a star feeder 102 and a first support foot 104 .

[0046] 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

[0061] Embodiment 2: A coal gangue identification device

[0062] refer to figure 2 , image 3 , this embodiment provides a structure of the gangue identification device in Embodiment 1.

[0063] 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

[0070] Embodiment 3: A kind of wheel-type gangue identification device

[0071] This embodiment provides another structure of the gangue identification device in Embodiment 1.

[0072] 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

An underground raw coal gangue discharge system, comprising: a material distribution queuing device, a coal and gangue identification device, a coal and gangue tracking unit, and a coal and gangue separation device; the material distribution queuing device is used to input mineral materials to the coal and gangue identification device; the coal and gangue identification device is used to measure The volume and weight of the mineral material, and identify the mineral material according to the volume and weight; the coal gangue tracking unit is used to track the identified mineral material according to the identification result of the coal gangue identification device; the coal gangue separation device is used to track the identified mineral material according to the The tracking result of the gangue tracking unit sorts the ore identified by the gangue identification device. In the present invention, a coal gangue tracking unit is set up. After the coal gangue is identified, the identified mineral material is tracked in real time according to the coal gangue identification result, and the directional delivery of the mineral material is controlled according to the tracking result, which avoids the The mixed cutting of coal and gangue ensures the accurate separation of coal and gangue after identification.

Description

technical field [0001] The invention relates to the field of coal gangue sorting equipment, in particular to an underground raw coal gangue discharge system. Background technique [0002] Coal and gangue identification and coal and gangue separation are indispensable in raw coal and gangue removal. At present, photoelectric separation is mainly used to separate coal and gangue. The photoelectric sorting device has precise structure, complex operation and high environmental requirements. Moreover, the γ-rays or X-rays used in the photoelectric separation device have the risk of radiation pollution, so its protective measures will be more complicated, so that the equipment design and installation will be limited by the limited space in the mine, and it cannot be operated in the mine. Moreover, after the identification of coal and gangue, the position changes in real time during the transportation process, and it is easy to cause mixing of coal and gangue. Contents of the i...
