Description

Technical Field

[0001] The utility model relates to the technical field of kaolin screening, in particular to a screening device for iron removal and purification of kaolin. Background Technique

[0002] The components of kaolin mainly consist of minerals such as kaolinite, halloysite, sericite, illite, montmorillonite, quartz, and feldspar. Pure kaolin is white, delicate, and soft, with good physical and chemical properties such as plasticity and refractoriness. Therefore, it is widely mined and used. When kaolin is mined, a screening device is needed to screen it and remove some impurities contained in the kaolin, such as impurities containing iron or other magnetic metals. The iron filings in the kaolin are sucked away by a rotating magnetic drum to complete the iron removal of kaolin. However, due to the direct inflow of kaolin, the kaolin can fall concentratedly, resulting in the fact that the magnetic drum cannot suck away the iron filings in the middle, thereby reducing the iron removal effect. For this reason, we propose a screening device for iron removal and purification of kaolin. Content of the Utility Model

[0003] The utility model provides a screening device for iron removal and purification of kaolin, which solves the problems raised in the above background technique.

[0004] To achieve the above purposes, the utility model is realized through the following technical solutions: A screening device for iron removal and purification of kaolin includes a main body. An inlet is opened at the top of the main body. A plurality of vertically arranged guiding plates are fixedly installed inside the main body, and a diversion plate corresponding to the guiding plates is fixedly installed inside the main body. The bottom end of the guiding plate is located at the top end of the diversion plate, and a rotatable magnetic drum is movably sleeved inside the main body. An electromagnetic device is fixed inside the magnetic drum. A plurality of discharge ports are opened at the position corresponding to the bottom end of the diversion plate inside the main body, and all the discharge ports are communicated with each other.

[0005] Optionally, a dispersion plate is movably connected to the bottom end of the guiding plate. A motor is fixedly installed on the outer side of the main body, and an output shaft of the motor is fixedly connected with a first gear.

[0006] Optionally, the first gear is connected inside the main body through a shaft pin, and a second gear is engaged on one side of the first gear. One end of a transmission wheel is fixedly installed at one end of the magnetic drum, and the second gear is fixed to one end of one of the transmission wheels.

[0007] Optionally, a rotating seat corresponding to the dispersion plate is movably sleeved inside the main body, and a second transmission belt is jointly sleeved on the outer sides of the transmission wheel and the rotating seat.

[0008] Optionally, one end of the rotating base is movably connected with a cross-shaped linkage base, and one end of the linkage base extending into the rotating base is fixedly connected with a spring, and one end of the spring is fixed to the rotating base.

[0009] Optionally, a plurality of continuous arc-shaped grooves are formed at one end of the linkage base extending out of the rotating base, and arc-shaped convex blocks corresponding to the linkage base are fixedly installed inside the main body, and the arc-shaped convex blocks can move into the arc-shaped grooves.

[0010] The utility model has the following beneficial effects:

[0011] 1. For the screening device for kaolin iron removal and purification, under the action of the reciprocating movement of the dispersion plate, the dispersion plate can relatively lay flat the kaolin, so that it can form a flat thin layer of kaolin along the guiding table board, effectively avoiding the accumulation of kaolin, and thus making the iron removal more thorough.

[0012] 2. For the screening device for kaolin iron removal and purification, through the multi-layer electromagnetic devices and magnetic adsorption drums, and with the cooperation of the dispersion plates on the corresponding layers, the kaolin can be screened layer by layer, and then the kaolin can be screened multiple times, avoiding the insufficient screening of iron filings caused by the too fast flow rate of kaolin, thus ensuring the iron removal effect.

And a rotatable magnetic adsorption roller 8 is movably sleeved inside the main body 1. An electromagnetic device 7 is fixed inside the magnetic adsorption roller 8, and the electromagnetic device 7 is fixed on the main body 1. Under the suction of the electromagnetic device 7, the iron filings in the kaolin can be adsorbed on the magnetic adsorption roller 8. Then, under the rotation of the magnetic adsorption roller 8, the magnetic adsorption roller 8 can drive the iron filings away from 70, so that the iron filings can be smoothly thrown out, thus achieving the effect of iron removal. A plurality of discharge ports 6 are opened at the position corresponding to the bottom end of the flow guiding plate 5 inside the main body 1, and all the discharge ports 6 are communicated. Through the discharge ports 6, the screened iron filings can be centrally processed, making it more convenient.

[0024] Please refer toFigures 1 to 6 Inside the main body 1, a rotating base 15 corresponding to the dispersion plate 9 is sleeved. The rotating base 15 can rotate at a fixed position on the main body 1. A second transmission belt 14 is commonly sleeved on the outer sides of the transmission wheels 11 and the outer side of the rotating base 15. Through the transmission of the second transmission belt 14, the rotating base 15 can rotate. At the same time, a first transmission belt 13 is commonly sleeved between the transmission wheels 11. Through the transmission of the first transmission belt 13, the transmission wheels 11 can rotate.

[0025] Please refer to Figures 1 to 6 One end of the rotating base 15 is movably connected to a cross-shaped linkage seat 16. Through the transmission of the rotating base 15, the linkage seat 16 can rotate. The linkage seat 16 can rotate at a fixed position on the rotating base 15. One end of the linkage seat 16 extending into the interior of the rotating base 15 is fixedly connected to a spring 18. One end of the spring 18 is fixed to the rotating base 15. Under the action of the elastic force of the spring 18, the linkage seat 16 can always be in contact with the arc-shaped convex block.

[0026] Please refer to Figures 1 to 6 One end of the linkage seat 16 extending out of the rotating base 15 is provided with a plurality of continuous arc-shaped grooves 17.

Under the action of the elastic force of the spring 18, the linkage seat 16 can rotate. The rotation of the linkage seat 16 can continuously contact the arc-shaped convex block, and then the linkage seat 16 can move back and forth, further enabling the dispersion plate 9 to move back and forth, so that the kaolin can slide down relatively flat through the diversion plate 5, and then the kaolin slides flat towards the magnetic adsorption drum 8. Under the suction of the electromagnet 7 and the centrifugal force of the rotation of the magnetic adsorption drum 8, the iron filings can be screened into the discharge port 6. Through the screening of multiple magnetic adsorption drums 8, the iron removal is more thorough.
