Background
The magnetic roller of the dry magnetic separator of the fly ash iron extraction production line is frequently invalid due to a sealing structure, and ash leakage phenomenon can occur in the running process of the production line. Because the fly ash materials are lighter, the fly ash leaks from the materials, so that dust drifts around, the field environment quality is poor, and the physical and psychological health of workers is not facilitated. Therefore, the improvement of the magnetic roller sealing structure of the existing dry magnetic separator, the prolongation of the service life of the magnetic roller sealing structure of the dry magnetic separator and the reduction of the failure risk of the sealing structure are the problems to be solved urgently.
The powdery particles fall down at the output end of the first row of magnetic rollers through a discharging opening in the dry magnetic separator, and nonmagnetic materials fall down under the driving of the rotation of the first row of spiral magnetic rollers; the magnetic material falls down at the input end by the driving of the spiral magnetic roller. The second magnetic roller is used for sorting the first magnetic material falling down, the third magnetic roller is used for sorting the second magnetic material falling down ┈ ┈, the sorting operation is repeated, and the filling packing of the output end and the input end in the magnetic separator is invalid under the condition of material scouring or abrasion, so that the magnetic roller of the magnetic separator leaks ash. The inner part of the dry magnetic separator cavity is driven by the air flow of the ash conveying pipe network to form a negative pressure state, and the worn magnetic roller gap between the output end and the input end has air flow to take out powdery materials and float in the air of a factory building. The dust concentration and the silicon dioxide content in the site exceed the standard, and the physical and mental health and mood of workers are affected. In order to avoid leakage, the maintenance or packing replacement operation can only be carried out after production stopping and shutdown, ash leakage occurs for several days in a few half months after the replacement of the graphite ethylene packing, and then the graphite ethylene packing is replaced, so that the workload is increased, and the cost is increased.

Detailed Description
The utility model is further described below with reference to the accompanying drawings:
the magnetic roller sealing structure of the dry magnetic separator comprises a shaft sleeve 2 group sleeved at two ends of a magnetic roller 1 of the dry magnetic separator, wherein the shaft sleeve 2 group comprises a circular sleeve 2 and a metal gasket; the inner diameter of the sleeve 2 is equal to the outer diameter of the magnetic roller, the sleeve 2 is made of wear-resistant materials, the sleeve 2 comprises a plurality of sleeves 2 which are sequentially sleeved, and a metal gasket 3 is sleeved behind the sleeve 2 at the outermost end. The end face of the sleeve pipe 2 at the outermost end is positioned in the dry magnetic separator frame box body 4, the outer surface of the dry magnetic separator frame box body 4 is connected with a pressing disc 5 for sealing the magnetic roller, an accommodating space is formed between the pressing disc 5 and the metal gasket, and wear-resistant particles are filled in the accommodating space. The length of the sleeve 2 is 8-12 mm.
The plurality of sleeves 2 spliced in sequence form a leakage-proof section of the sealing structure, and the metal gasket and the subsequent wear-resistant particles form an isolation section of the sealing structure.
According to the technical scheme provided by the utility model, the leakage-proof section positioned in the dry magnetic separator frame box body 4 has good flushing resistance, so that the problem that the magnetic roller leaks materials due to inner cavity pressure or packing abrasion, the screening operation of powdery particles is influenced, the working environment is improved, the cost is saved, and the workload is reduced.
