DETAILED DESCRIPTION

[0024] Combined with attachment Figure 1-6As shown, an intelligent coal beneficiation device includes a feeding unit 1, a discharging unit 2, a ray identification unit 3, a separation unit 4, a conveying unit 5, a dispersion unit 6 and a restriction unit 7. The feeding unit 1 and the discharging unit 2 are respectively arranged on both sides of the conveying unit 5, and the dispersion unit 6, the restriction unit 7, the ray identification unit 3 and the separation unit 4 are sequentially arranged on the conveying unit 5. The feeding unit 1 is connected to the dispersion unit 6, and the separation unit 4 is connected to the discharging unit 2. The coal material enters the conveying unit 5 through the feeding unit 1, and the input coal material is conveyed by the conveying unit 5. The coal material on the conveying unit 5 is broken up by the conveying unit 5 so that it can be evenly conveyed on the conveying unit 5. The stacking height of the coal material is limited by the restriction unit 7, so as to prevent the coal material from being piled up too high and affecting the recognition accuracy of the ray identification unit 3. The coal material detected by the ray identification unit 3 is separated by the separation unit 4 and enters the discharging unit 2 for output.

[0025] In some embodiments, the dispersion unit 6 includes a dispersion motor 61, a dispersion rocker arm 62, a dispersion crank 63, a dispersion connecting rod 64 and a rocker shaft 65. The rocker shaft 65 is fixedly arranged above the conveying unit 5, and the top of the dispersion rocker arm 62 is rotatably mounted on the rocker shaft 65. The side end of the dispersion rocker arm 62 is rotatably mounted with a dispersion connecting rod 64. The dispersion crank 63 is fixedly mounted on the output end of the dispersion motor 61. The dispersion motor 61 drives the dispersion crank 63 to rotate along the output shaft of the dispersion motor 61. One end of the dispersion crank 63 is hinged to the dispersion connecting rod 64. The dispersion crank 63 is rotated by the rotation of the dispersion motor 61, and the dispersion rocker arm 62 is driven to move by the dispersion crank 63. The dispersion connecting rod 64 is driven to swing back and forth along the axis of the rocker shaft 65 by the dispersion rocker arm 62. The coal material on the conveying unit 5 is dispersed, swung and combed by the reciprocating swing of the dispersion rocker arm 62, so that the coal material on the conveying unit 5 moves evenly.

[0026] In some embodiments, the dispersion unit 6 also includes a dispersion shell 66, the dispersion rocker arm 62, the dispersion crank 63 and the dispersion connecting rod 64 are respectively located on the inner side of the dispersion shell 66, and the dispersion motor 61 is fixedly installed on the side end of the dispersion shell 66. The output end of the dispersion motor 61 passes through the dispersion shell 66 and is transmission-connected to the dispersion crank 63 located on the inner side thereof. The dispersion unit 6 is covered by the set dispersion shell 66 to prevent the coal mineral material from flying during the operation of the equipment.

[0027] In some embodiments, the dispersion unit 6 also includes a dispersion rake 67, which is fixedly installed at the lower end of the dispersion rocker arm 62. The dispersion rake 67 can cover a larger range, thereby improving the efficiency and uniformity of the dispersion unit 6 in breaking up the coal ore on the conveying unit 5.

[0028] In some embodiments, two dispersion units 6 are provided, and the two dispersion units 6 are symmetrically arranged on both sides of the interior of the dispersion shell 66. The dispersion rocker arms 62 on the two dispersion units 6 are driven in opposite directions. During the operation of the equipment, the staggered reciprocating swings of the two dispersion units 6 can improve their effect on breaking up the coal ore and increase the uniformity of coal ore transportation.

[0029] In some embodiments, the limiting unit 7 includes a limiting shell 71, a lifting mechanism 72 and a limiting hopper 73. The limiting shell 71 is fixedly mounted on the conveying unit 5, the lifting mechanism 72 is arranged on the limiting shell 71, and the limiting hopper 73 is installed on the lifting mechanism 72. The limiting hopper 73 is in the limiting shell 71 and is on the conveying unit 5. The lifting mechanism 72 controls the limiting hopper 73 to move in the vertical direction. The setting of the lifting mechanism 72 can control the limiting hopper 73 to be raised and lowered in the limiting shell 71, thereby controlling the setting height limit, thereby ensuring that the current batch of mineral materials can be detected by the radiation identification unit 3.

[0030] In some embodiments, the limiting hopper 73 is set at an angle, and the side of the limiting hopper 73 close to the dispersion unit 6 is set at a height lower than the side close to the radiation identification unit 3; when in use, when the coal material piled up by the conveying mechanism is higher than the set height, the coal material will enter the hopper, and when the coal material driven by the conveying mechanism is lower than the limited height, the coal material previously piled up in the hopper will slide down to the conveying unit 5 under the action of gravity.

[0031] In some embodiments, the lifting mechanism 72 includes a lifting motor 721, a lifting screw 722, a lifting slide 723, a lifting slide frame 724 and a lifting spring 725. The lifting slide frame 724 is vertically slidably set on the limiting shell 71, and the mineral hopper is fixedly installed below the lifting slide frame 724. The lifting spring 725 is sleeved on the lifting slide frame 724. The lifting spring 725 presses down the lifting slide member, and the lifting slide member 723 is horizontally slidably set on the upper end surface of the limiting shell 71. The lifting screw 722 is horizontally set on the limiting shell 71. The lifting slide member 723 is provided with a screw groove that fits with the lifting screw 722. The output end of the lifting motor 721 is connected to the lifting screw 722 for transmission. The lifting motor 721 rotates to drive the lifting screw rod 722 to rotate and drive the lifting slide 723 to slide horizontally on the limiting shell 71. The upper end surface of the lifting slide 723 is inclined, and the top of the lifting slide frame 724 is provided with a sliding frame top plate 726. The lower end surface of the sliding frame top plate 726 is provided with an inclined surface that fits with the upper end surface of the lifting slide 723. The lifting motor 721 drives the lifting screw rod 722 to rotate, and the lifting screw rod 722 drives the static slide to move horizontally. While the lifting slide 723 moves horizontally, it cooperates with the sliding frame top plate 726 to adjust the height of the lifting slide. The lifting spring 725 provided can facilitate the downward movement of the lifting slide frame 724, thereby preventing the lifting slide frame 724 from being stuck.

[0032] In some embodiments, a vibration motor 727 is provided on the top plate 726 of the sliding frame. The vibration motor 727 can drive the sliding integral lifting sliding frame 724 to vibrate, thereby facilitating the shaking out of the coal material in the ore hopper.

The conveying unit 5 conveys the mineral material between the radiation source and the radiation source receiving device, activates the radiation source to emit radiation that passes through the mineral material and is received by the radiation source receiving device, and determines the type of the current mineral material based on the received radiation data;

[0034] The separation unit 4 includes a nozzle row with a plurality of nozzles. The moving position of the mineral material is determined based on the mineral material data identified by the ray recognition unit 3 and the conveying speed of the conveying unit 5. When the mineral material moves to the appropriate position, the nozzle at the corresponding position is activated to generate aerodynamic force to push the mineral material to the appropriate position.

[0035] The conveying unit 5 includes a conveying motor, a main power roller, a driven power roller and a conveyor belt. The main power roller and the driven power roller are arranged at intervals. The conveyor belt is sleeved on the main power roller and the driven power roller. The conveying motor is connected to the main power roller through a transmission. The main power roller can be driven by the conveying motor to operate, thereby driving the conveyor belt to drive the mineral material to be conveyed.
