Description
Technical field
This utility model belongs to the wear Protection device of grinding attachment inwall, relates to the abrasion-proof backing block with permanent magnetism being prepared from by permanent magnet material, both abrasive rubbers compound.
Background technology
Tower grinding machine is a kind of vertical mixing ore grinding equipment, and its stirring cylinder inboard wall is chronically at Frotteurism, and wear extent is very big, therefore adheres to anti-wearing liner on the inwall of cylinder.The effect of anti-wearing liner is that instead of cylinder and rubs with ore pulp in cylinder and milling medium, and therefore wear extent is bigger, it is necessary to often change；And inner barrel narrow space, therefore change workload relatively big, labor intensity of operating staff is big, affects equipment service efficiency；Meanwhile, with bolts between current lining and cylinder, the ore pulp of the inside and milling medium are likely to from the hole of cylinder to reveal, thus affecting onsite application environment.
Summary of the invention
Problem to be solved in the utility model is to provide the abrasion-proof backing block that a kind of anti-wear performance is excellent, and its service life is very long, it may be achieved life-time service is free of replacement, and omnidistance non-maintaining, it is not necessary to labor intensive thing, substantially increases equipment service efficiency.Meanwhile, this novel lining plate it also avoid the material leakage in tower grinding machine cylinder.
This utility model one combined multi-stage magnetic liner plate, it includes some pieces of ndfeb magnets, abrasive rubber；Abrasive rubber is tabular, and its A face has several square grooves, and ndfeb magnet is placed in the square groove of abrasive rubber；Be N pole before first ndfeb magnet, after be S pole, be S pole before second ndfeb magnet of its next-door neighbour, after be N pole, the rest may be inferred: the magnetic level of namely adjacent ndfeb magnet is in opposite direction.
Wherein, abrasive rubber is the flexible material of the wear resistant corrosion resistants such as neoprene, nitrile rubber or polyurethane.
This utility model in use, utilizes the magnetic of ndfeb magnet itself to make to be adsorbed in tower grinding mill barrel below the A face of abrasive rubber and ndfeb magnet, has the magnetic liner plate that some pieces of bases are novel in whole cylinder.This novel operation principle is: the high-gradient magnetic field produced after utilizing ndfeb magnet to magnetize, make the B face of abrasive rubber is tightly adsorbed steel ball and magnetic mineral fine, form one layer of exogenous overcoat, thus substituting steel ball that liner plate self and inner barrel constantly stir and breeze rubs.Even if being worn disappearance also can supplement rapidly the overcoat that generation is new under the action of a magnetic field.Therefore in actual use, the life-span of this magnetic liner plate is very long, it might even be possible to accomplish non-maintaining free of replacement, can thoroughly replace alloy wear resistant lining plate and wear-resistant rubber liner completely.Simultaneously as composite magnetic liner plate is to be wrapped magnetic piece by the rubber in outside, it is possible to avoid magnetic piece to be immersed in subject to corrosion in the ore pulp that corrosivity is stronger.Further, since rubber self is flexible, it is also possible to reduce the pinch shock that magnetic piece is subject to, it is to avoid in use self crushes.
Therefore, service life of the present utility model is very long, it may be achieved life-time service is free of replacement, and omnidistance non-maintaining, it is not necessary to labor intensive thing, substantially increases equipment service efficiency.Simultaneously as it is to utilize magnetic absorption in tower grinding mill barrel, it is not necessary to perforate on tower grinding mill barrel, thus avoids the material in cylinder and reveal.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
From accompanying drawing it can be seen that this utility model one combined multi-stage magnetic liner plate, it includes some pieces of ndfeb magnets, abrasive rubber 2；Abrasive rubber 2 is tabular, and its A face has several square grooves, and ndfeb magnet is placed in the square groove of abrasive rubber 2；Be N pole before first ndfeb magnet 1-1, below for S pole, be S pole before ndfeb magnet the 2nd 1-2 of its next-door neighbour, after be N pole, the rest may be inferred: the magnetic level of namely adjacent ndfeb magnet is in opposite direction.Certainly, can also be S pole before the first ndfeb magnet 1-1, below for N pole, be N pole before the second ndfeb magnet 1-2 of its next-door neighbour, after be S pole.Namely, in monoblock magnetic liner plate, the adjacent ndfeb magnet polar contribution on same surface is contrary, and namely N pole, S pole, N pole or S pole, N pole, S pole, be multistage magnetic.
Wherein, the thickness of ndfeb magnet is 15-40mm, concrete size is varied from according to the size being suitable for cylinder, ndfeb magnet thickness is more thick, the surface induction intensity of magnetic liner plate is more big, the steel ball of surface adsorption and breeze are also more many, but on grinding power consumption and running efficiency generation impact, generally can be advisable less than 40mm.
Wherein, abrasive rubber 2 can be chosen as the flexible material of the wear resistant corrosion resistants such as neoprene, nitrile rubber or polyurethane according to the kind processing material.
In the fabrication process, first ndfeb magnet is magnetized to saturation, it is fixed in unitary mould according to the opposite polarity order of adjacent magnetic piece, carry out filling and sulfuration, the curing process of rubber or polyurethane material again, ndfeb magnet and abrasive rubber in the produced magnetic liner plate of this technique combine very tight, even if in use operating mode is very severe without coming off.
As a kind of improved procedure that this is novel, the A face portion that abrasive rubber 2 is between ndfeb magnet two pieces adjacent is provided with groove 3.So, whole liner plate can bend so that it is adhesively tightr with side in arc tube body.
As another improved procedure that this is novel, the B face of abrasive rubber 2 is provided with right-angled trapezium projection 4.In use right-angle side is contrary with mixing direction, it is possible to stop the steel ball rolling at backing surface.Meanwhile, in order to not reduce the intensity of liner plate, the optimum position of right-angled trapezium projection 4 is corresponding with the position of groove 3.
From accompanying drawing, the scheme that this utility model provides is to have the permanent magnet ndfeb magnetic piece of three kinds of polarity in monoblock composite magnetic liner plate.The program is also extensible for there being the permanent magnet ndfeb magnetic piece of four kinds of polarity or more kinds of polarity in monoblock composite magnetic liner plate.That is: this novel middle ndfeb magnet is at least three pieces.
This utility model in use, utilizes the magnetic of ndfeb magnet itself to make to be adsorbed in tower grinding mill barrel below the A face of abrasive rubber and ndfeb magnet, has the magnetic liner plate that some pieces of bases are novel in whole cylinder.This novel operation principle is: the high-gradient magnetic field produced after utilizing ndfeb magnet to magnetize, make the B face of abrasive rubber is tightly adsorbed steel ball and magnetic mineral fine, form one layer of exogenous overcoat, thus substituting steel ball that liner plate self and inner barrel constantly stir and breeze rubs.Even if being worn disappearance also can supplement rapidly the overcoat that generation is new under the action of a magnetic field.Therefore in actual use, the life-span of this magnetic liner plate is very long, it might even be possible to accomplish non-maintaining free of replacement, can thoroughly replace alloy wear resistant lining plate and wear-resistant rubber liner completely.Simultaneously as composite magnetic liner plate is to be wrapped magnetic piece by the rubber in outside, it is possible to avoid magnetic piece to be immersed in the ore pulp that corrosivity is stronger and be corroded.Further, since rubber self is flexible, it is also possible to reduce the pinch shock that magnetic piece is subject to, it is to avoid in use self crushes.
Therefore to provide a kind of life-span longer for this utility model, installs tower grinding mill barrel wearing layer more easily.
