The ore pulp can be in various forms, for example, the ore pulp can be slurry formed by mixing gasification filter cake and water; specifically, the element composition of the gasified filter cake contains a large amount of magnetic elements such as Fe, Mn, Ti and the like besides main elements such as Si, Al, Ca and the like, and inorganic mineral substances formed by the magnetic elements are also main contributors of the ash content of the gasified filter cake, so that the magnetic device can selectively attract and carry fine ash downwards in a magnetic attraction manner according to the magnetic difference of the minerals so as to further reduce the ash content in the ore pulp. It should be noted that the coarse ash particles and the fine ash are particles with higher ash content, and the difference is that the particle size of the coarse ash particles is larger than that of the fine ash particles; by char-containing slurry is meant a slurry of the pulp after removal of coarse ash particles and fine ash, wherein the char content of the char-containing slurry is much higher than the char content of the pulp.

Further, magnetic means includes magnetic force piece 13 and moving mechanism, magnetic force piece 13 sets up to attract through the magnetism mode fine ash, moving mechanism sets up to drive magnetic force piece 13 moves down, so that fine ash is in move down under magnetic force piece 13's the drive effect, and the structure is more simple, and the design is more reasonable. The magnetic member may be in various forms, such as a magnet, etc.

Further, as shown in fig. 1, the moving mechanism includes a motor 8, a support 15 and a chain transmission assembly, the chain transmission assembly includes a chain 9, a driving sprocket 10 and a driven sprocket 11, the magnetic member 13 is installed on the chain 9, the driving sprocket 10 is disposed below the driven sprocket 11 and is in transmission connection with the driven sprocket 11 through the chain 9, the driving sprocket 10 and the driven sprocket 11 are installed on the support 15, and a driving shaft of the motor 8 is in transmission connection with the driving sprocket 10, so that the motor 8 can drive the chain 9 to rotate through the driving sprocket 10, and the structure is simpler, and is convenient to manufacture and process. When the magnetic chain wheel is used, the motor 8 drives the driving chain wheel 10 to rotate through the driving shaft, the driving chain wheel 10 drives the driven chain wheel 11 to rotate through the chain 9, and the chain link of the chain 9, which is provided with the magnetic part 13, moves downwards. In addition, the driving shaft of the motor 8 can also be in transmission connection with the driving chain wheel 10 through a speed reducer.

Further, the shell comprises a cylindrical portion 6 and a conical portion 7, the conical portion 7 is wide at the top and narrow at the bottom and is connected to the bottom of the cylindrical portion 6, the charcoal discharge port is formed in the top of the cylindrical portion 6, the ash discharge port 5 is formed in the bottom of the conical portion 7, the driven sprocket 11 is arranged outside the cylindrical portion 6, the driving sprocket 10 is arranged outside the conical portion 7, the chain transmission assembly further comprises a steering sprocket 12 located at the junction of the cylindrical portion 6 and the conical portion 7, the steering sprocket 12 is in transmission connection with the chain 9 and can change the extending direction of the chain 9, fine ash can be moved downwards to the ash discharge port 5 under the driving action of the magnetic member 13, and fine ash in the cyclone chamber 3 can be discharged smoothly.

Through the structure, the connecting line of the driving chain wheel 10 and the steering chain wheel 12 is intersected with the connecting line of the steering chain wheel 12 and the driven chain wheel 11 to form a bending connecting line together, and the space between two parts of the chain 9 positioned at two sides of the bending connecting line and the shell is also different; when the dust remover is used, the driving sprocket 10 can drive the chain 9 to rotate, so that one part of the chain 9 close to the housing moves downwards, and the other part of the chain 9 far away from the housing also moves upwards, and in view of the fact that the magnetic member 13 on one part of the chain 9 is closer to the housing (which is equivalent to the magnetic member 13 on the other part of the chain 9), the fine dust in the chamber 3 moves downwards along with the magnetic attraction of the magnetic member 13 on the part, and therefore the fine dust can be smoothly discharged out of the chamber 3 from the dust discharge port 5.

Further, the separation device comprises an overflow pipe 4, wherein the overflow pipe 4 is arranged to be inserted into the chamber 3 from the charcoal discharge port and can output the charcoal-containing slurry out of the chamber 3.

According to some embodiments of the present invention, when the separation device performs ash removal separation operation on the ore pulp, the specific process is as follows: firstly, when the water medium swirler initially works, the working pressure of the water medium swirler is normally adjusted, and the water medium swirler can be normally driven without being blocked as long as the water medium swirler is ensured; then, after the working condition of the water medium cyclone is stabilized, the rotating speed of the motor 8 is adjusted by the frequency converter 14, specifically, when the ash content of the high ash product (wherein the high ash product refers to a product with higher ash content, namely the above mentioned coarse ash particles and fine ash) at the ash discharge port 5 of the water medium cyclone is lower than the process requirement, the rotating speed of the motor 8 is reduced by the frequency converter 14 to reduce the rotating speed of the chain 9, so that the magnet can more stably drive the fine ash to move downwards to increase the ash content of the high ash product discharged from the ash discharge port 5, otherwise, the rotating speed of the chain 9 is increased by the frequency converter 14. In addition, if the rotating speed of the chain still cannot meet the technological requirements by adjusting, the brand of the magnet can be replaced to improve the magnetic field intensity; if the process requirements can not be met by changing the marks of the magnets, the caliber of the ash discharge port 5 (namely, the flow area of the ash discharge port 5) and the insertion depth of the overflow pipe 4 can be adjusted, so that the high-ash product at the ash discharge port 5 can meet the process requirements.
