Problems solved by technology

Almost all the current coal preparation plants in my country have raw coal preparation workshops, and most mines without coal preparation plants also have raw coal preparation workshops. With the increase of the gangue content of raw coal mined in some mines, the original design The advanced screening and sorting system can no longer meet the current mine production and coal quality requirements, which seriously restricts the development of the mine and the sales of products

Embodiment 1

[0057] see figure 1 As shown, the intelligent gangue selection method comprises the following steps:

[0058] -Primary screening of raw coal, and control of raw coal blanking speed and weight after screening;

[0059] - The industrial camera 52 collects images of the raw coal that is partly blanked and sends them to the control unit 50. The control unit 50 calculates the position of the gangue according to the image data and controls the first manipulator 53 to remove the gangue. The processing flow of the control unit 50 for receiving image data is as follows: Image input, image preprocessing, image feature extraction, image recognition classification and output results;

[0060] -Acquisition and analysis of the second image of the raw coal after gangue removal, check whether there is gangue in the raw coal, and when it is judged that there is gangue that has not been discharged, the control unit 50 controls the second manipulator 56 to discharge the gangue that has not been...

Embodiment 2

[0078] see Figure 2-6 Shown, a kind of intelligent gangue selection device comprises:

[0079] The first conveying assembly 10 is used for conveying raw coal;

[0080] The first sieve plate 20, the first sieve plate 20 is arranged obliquely, the inclined high end is arranged below the discharge end of the first conveying assembly 10, and the inclined bottom end is connected with a blanking assembly 60 for controlling the blanking speed of raw coal;

[0081]The second conveying assembly 70 is used to receive the blanking of the blanking assembly 60, and the receiving end is provided with a counter 54 for counting the blanking, an industrial camera 52 for obtaining images of the blanking, and a first second for removing gangue. A manipulator 53, a second industrial camera 55 and a second manipulator 56 are provided at the discharge end of the second conveying assembly 70,

[0082] Wherein, industrial camera 52, counter 54, first manipulator 53, second industrial camera 55 and...

Embodiment 3

[0098] The present invention actually carries out gangue selection operation:

[0099] S10. According to the shaking mode of the first sieve plate 20 by rotating the first sieve plate 20 according to the type of gangue selection, specifically select the shaking of the shaking assembly 30 or the shaking of the runner 23, and select the transmission speed of the first transmission assembly 10 and the second transmission assembly 70 according to the selection of gangue. .

[0100] S20. Put the raw coal on the first conveying assembly 10, the raw coal falls onto the first sieve plate 20, and the first sieve plate 20 sieves the material to remove particles with a particle size of less than 50mm, and the control unit 50 controls the blowing The blowing speed of the air unit 50 prolongs the residence time of the material on the first sieve plate 20, and the screened small particles fall into the first collecting box 40 for further sorting;

[0101] S30, the screened material falls t...

Abstract

The invention discloses an intelligent gangue selection method and device, which belong to the technical field of coal mine separation. The gangue selection method of the present invention includes the following steps: primary screening of raw coal, and controlling the raw coal blanking speed and component blanking after screening; industrial camera The image acquisition of the batched raw coal is carried out and sent to the control unit, and the control unit calculates the position of the gangue based on the image data and controls the first manipulator to remove the gangue; the secondary image acquisition and analysis of the raw coal after the gangue is removed. The invention also discloses an intelligent gangue selection device. The invention pre-screens the raw coal and then performs intelligent gangue discharge, which realizes the discharge of large and small-sized gangue while the raw coal selection operation is in progress, and effectively avoids misuse of dust, coal, etc. Misjudgment results of gangue selection caused by mud, etc., improve the efficiency and quality of gangue sorting.

Description

technical field [0001] The invention belongs to the technical field of coal mine separation, and in particular relates to an intelligent gangue separation method and device. Background technique [0002] In recent years, with the promotion of caving coal mining technology and the deepening of mine development, the amount of gangue in raw coal has also increased, and the gangue content of raw coal in some mines has risen to 2 to 3 times the original. Almost all the current coal preparation plants in my country have raw coal preparation workshops, and most mines without coal preparation plants also have raw coal preparation workshops. With the increase of the gangue content of raw coal mined in some mines, the original design The advanced screening and sorting system can no longer meet the current mine production and coal quality requirements, which seriously restricts the development of mines and the sales of products. Contents of the invention [0003] The first object of ...
