Abstract
The utility model discloses a wear-resistant magnetic extractor roller comprising an inner roller body, an outer roller body and a shaft, wherein the inner roller body is a cylindrical thin-wall roller made of austenitic stainless steel materials, both ends of the inner roller body are provided with extended shafts with the coaxial-line structures, and the outer roller body is made of ceramic materials and is coaxially sleeved on the outer wall of the inner roller body. In the utility model, the inner roller body and the outer roller body are made of nonmagnetic materials and are beneficial to increasing the quality and the efficiency for choosing iron ore, moreover, the outer roller body which is in direct contact with iron sand is made of the ceramic materials with better wear-resisting property, therefore, the service life of the roller is greatly prolonged, the maintaining workload is reduced in the producing process, work hours are reduced and the use benefits are increased. The utility model is suitable for magnetic extractor rollers with various specifications.
Description
Technical field
The utility model relates to a kind of wear-resisting formula magnetic separator cylinder of iron ore choiceness equipment, particularly a kind of external ceramic jacket.
Background technology
Magnetic separator is the indispensable equipment of iron ore choiceness, and in order to improve choicest quality and efficient, the magnetic separator cylinder does not allow magnetic in the use.Prior art is generally made the magnetic separator cylinder with stainless steel or nonmetallic materials, and the cylinder of this type of material can be avoided being magnetized fully.But the wearability of this type of material can not satisfy the instructions for use of magnetic separator.Existing a kind of technical scheme can solve wear-resisting problem preferably in the prior art, and it is external one deck rubber sleeve on cylinder outer wall, utilizes its anti-wear performance to remedy stainless deficiency.However, the intrinsic shortcoming of rubber material is easily aging, ageing of rubber restricted join service life of magnetic separator cylinder.Generally speaking, neither one mature technique scheme can increase substantially magnetic separator cylinder service life in the prior art.
The utility model content
The utility model is primarily aimed at the deficiencies in the prior art, proposes a kind of wear-resisting formula magnetic separator cylinder of external ceramic jacket, and this composite construction is simple, rationally utilizes superpower anti-wear performance of pottery and the performance that is not magnetized, and increases substantially cylinder service life.
The utility model is achieved through the following technical solutions technical goal.
Wear-resisting formula magnetic separator cylinder, it comprises inner barrel, outer cylinder body and axle.Described inner barrel is the cylinder-shaped thin wall tube of austenitic stainless steel material, and its two ends are provided with the outrigger shaft of coaxial line structure, and its improvements are: described outer cylinder body is a ceramic material, and outer cylinder body is coaxial to be linked on the inner barrel outer wall.
In the said structure, the material of outer cylinder body is the alundum (Al pottery, its wall thickness 2mm～5mm.
The utility model compared with prior art has following good effect:
1, compound one deck pottery simple in structure on the inner barrel outer wall made easily;
2, the outer cylinder body abrasive resistance of ceramic material is strong, the service life of improving cylinder greatly;
3, the used material of inner barrel and outer cylinder body is all nonmagnetic, helps improving iron ore choiceness quality and efficient.
Description of drawings
Fig. 1 is the utility model structural profile schematic diagram.
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.
Wear-resisting formula magnetic separator cylinder shown in Figure 1, it comprises inner barrel 1, outer cylinder body 2 and axle 3.Described inner barrel 1 is the cylinder-shaped thin wall tube of 1Cr18Ni9Ti material, and its two ends are provided with the outrigger shaft 3 of coaxial line structure.Outer cylinder body 2 coaxial being compounded on inner barrel 1 outer wall, outer cylinder body 2 is the alundum (Al pottery, the wall thickness of outer cylinder body 2 is 3mm in the present embodiment.The material that inner barrel 1 and outer cylinder body 2 used materials all are not magnetized in the utility model, help improving iron ore choiceness quality and efficient, and are the good especially ceramic materials of anti-wear performance with outer cylinder body 2 that iron ore directly contacts, so cylinder improves service life greatly, also reduce the workload of maintaining in the production, not only saved man-hour but also increase utilization benefit.
