Description

Technical Field

[0002] As a mechanical device that relies on friction to continuously transport materials, the core components of a belt conveyor include a frame, a conveyor belt, support rollers, a drive roller, a tension adjustment system, and a power transmission component. This equipment can realize the flow of materials from the starting feeding point to the terminal unloading point on a preset conveying path. It is suitable for both bulk material handling and packaged goods transportation. In addition, it can also be flexibly integrated into the process flow of various industrial production processes to build a coordinated and orderly automated material transportation line.

The rotation of the vertical rod 13 can drive the first rotating shaft 19 to rotate through the third bevel gear 21 and the fourth bevel gear 20, and the rotation of the first rotating shaft 19 can drive the positive conductive cylinder 11 to rotate.

[0020] See also Figure 1 , Figure 8 and Fig. 9 A dust collecting device is provided at the bottom of the positive conductive cylinder 11, and the dust collecting device includes a collecting box 12, and the collecting box 12 is fixedly connected to the left wall of the feeding port 9. The collecting box 12 is located below the positive conductive cylinder 11, and an inclined scraper 23 is fixedly connected to the side wall of the collecting box 12. The upper side of the scraper 23 is against the side wall of the positive conductive cylinder 11. When the positive conductive cylinder 11 rotates, the dust adsorbed on the surface of the positive conductive cylinder 11 will be scraped off by the scraper 23 and fall into the collecting box 12 for unified collection.

[0021] A plurality of magnet plates 22 are arranged in the fixed cylinder 1, each magnet plate 22 is made of high-strength neodymium iron boron magnet, a protective pad 24 is fixedly connected to the upper side of each magnet plate 22, and the protective pad 24 is made of rubber material, and a plurality of magnet plates 22 are connected to the left and right side walls of the fixed cylinder 1 in an inclined staggered sliding manner, and each magnet plate 22 is connected to the side wall of the fixed cylinder 1 through a vibration device, and each vibration device includes a sliding rod 27, and the sliding rod 27 is fixedly connected to the bottom side wall of the magnet plate 22, and the bottom end of the sliding rod 27 is fixedly connected to a baffle 28, and the sliding rod 27 is fixedly connected to the bottom side wall of the magnet plate 22.

A vibration spring 25 is sleeved on the side wall of the sliding rod 27, and the two ends of the vibration spring 25 are respectively against the side walls of the magnet plate 22 and the support plate 26. When each magnet plate 22 is impacted, the magnet plate 22 vibrates up and down under the action of the vibration spring 25. When multiple magnet plates 22 vibrate up and down, the induction wire 7 wound on the outside of the fixed cylinder 1 will cut the magnetic flux lines of multiple magnet plates 22, so that an induced current is generated on the induction wire 7.

[0022] One side of the positive conductive cylinder 11 penetrates the side wall of the feeding port 9 and extends into the feeding port 9. The side of the feeding port 9 away from the positive conductive cylinder 11 is fixedly connected with the negative conductive plate 10. A plurality of conductive spikes are arranged on the side wall of the negative conductive plate 10. The outer wall of the fixed cylinder 1 is wound with an induction wire 7. The induction wire 7 is electrically connected to the second fixed plate 29 and the negative conductive plate 10 through a rectifier filter 32. Figure 6 As shown, both ends of the induction wire 7 are electrically connected to the input end of the rectifier filter 32. The rectifier filter 32 is used to convert the induced alternating current generated by the induction wire 7 into direct current. Then, the rectifier filter 32 outputs the converted direct current at the positive and negative ends, respectively, and electrically connects the second fixed plate 29 and the negative conductive plate 10. The second fixed plate 29, the conductive bearing 30, the second rotating shaft 31, the positive conductive cylinder 11 and the negative conductive plate 10 are all made of conductive materials, and the first rotating shaft 19 and the fixed cylinder 1 are made of insulating materials.

[0023] The working principle of the present invention is: When the gangue to be filled needs to be transported from the conveyor belt 3, the motor 16 can be started first. The motor 16 drives the conveyor belt 3 to rotate by driving the roller shaft 5, and then the gangue is put into the upper end of the feeding port 9. After being put into the fixed cylinder 1, the gangue will slide down from the multiple vertically staggered magnet plates 22 in turn. Finally, after the gangue slides down from the bottom magnet plate 22, it will flow from the discharge port 2 to the conveyor belt 3 for transportation. By using the multiple magnet plates 22 to fully unload the gangue and slowly guide it to roll onto the conveyor belt 3, a smooth connection of the mineral material transfer is achieved, and the contact impact between the conveyor belt 3 and the mineral material is reduced; When each magnet plate 22 is impacted by coal gangue, the vibration spring 25 on the bottom side of the magnet plate 22 can not only buffer and absorb the kinetic energy of the magnet plate 22, thereby achieving energy absorption buffering of the mineral material, but also the vibration spring 25 can make the magnet plate 22 vibrate up and down. When multiple magnet plates 22 vibrate up and down, the induction wire 7 wound on the outside of the fixed cylinder 1 will cut the magnetic flux lines of multiple magnet plates 22, so that an induced current is generated on the induction wire 7. After the induced alternating current on the induction wire 7 is converted into direct current through the rectifier filter 32, the positive and negative ends of the direct current output are electrically connected to the second fixed plate 29 and the negative conductive plate 10 respectively, and the positive conductive cylinder 11 is electrically connected to the first fixed plate 29 and the negative conductive plate 10 respectively. The two fixed plates 29 are conductively connected, so a large amount of positive charges will be gathered on the positive electrode conductive cylinder 11, and a large amount of negative charges will be gathered on the negative electrode conductive plate 10. The large amount of negative charges on the negative electrode conductive plate 10 will produce tip discharge on the conductive spikes on the side wall of the negative electrode conductive plate 10, releasing a large amount of electrons in the air. A large amount of electrons will move toward the positively charged positive electrode conductive cylinder 11. At this time, a large amount of dust generated in the feeding port 9 when the coal gangue is put in is also carried away by a large amount of electrons and floats toward the positive electrode conductive cylinder 11, so that the dust in the feeding port 9 is adsorbed on the side wall of the positive electrode conductive cylinder 11, so as to prevent the dust from escaping into the air and polluting the environment; While the roller 5 is rotating, the roller 5 can drive the vertical rod 13 to rotate through the first bevel gear 18 and the second bevel gear 15. The rotation of the vertical rod 13 can drive the first rotating shaft 19 to rotate through the third bevel gear 21 and the fourth bevel gear 20. The rotation of the first rotating shaft 19 can drive the positive conductive cylinder 11 to rotate. The rotation of the positive conductive cylinder 11 can cause the dust adsorbed on the surface of the positive conductive cylinder 11 to be scraped off by the scraper 23 and fall into the collection box 12 for unified collection.
