Description
Technical field
The present invention relates to a kind of rotor block of vertical shaft crusher, belong to impact crushing equipment technical field.
Background technology
Vertical shaft crusher and impacting vertical crusher, the core of its fragmentation is rotor block, the profile of rotor block is a hollow cylinder, by upper, lower rotor part dish and the cutting plate combination be positioned between the two are formed, rotor block is divided into multiple transmitting runner by the cutting plate on rotor between dish and lower wall, enter at transmitting runner, outlet is provided with the sub butt ends that special material is made, thrower head, deflector and counterpunch board, the center of rotor block is charging hole, material separating disc is provided with in the bottom of charging hole, after material is admitted to rotor block, material first contacts with the material separating disc moved with rotor block, under the effect of material separating disc and sub butt ends, material enters different transmitting runners, and under centrifugal force accelerate to the impelling of 60-75m/s speed and go out, impact the material lining in Turbulent chamber, carry out strong certainly pulverizing.
In use material is dispersed in rotor block after contacting with sub butt ends, under centrifugal force to fly out rotor block from thrower head again, because material mutually launches between crusher chamber and rotor block, so thrower head, counterpunch board and deflector also belong to vulnerable part, often need change it.Thrower head in existing vertical shaft crusher rotor is column type, mounting means is that thrower head two ends are inserted into the upper of rotor block respectively, lower wall, need during replacing completely rotor to be separated, dismantle related 3 groups of parts could keep in repair, change and have very large difficulty, no matter existing thrower head vertical shaft breaks rotor entirety by the wear resistant material piece being what shape simultaneously, same position is all adopt one-piece parts to make, so no doubt there is structure simple, advantage easy to make, if but in monoblock, have subregion to occur the problem of serious wear, will require that monoblock is replaced, have the lower problem of effect.
Simultaneously at material from the process that rotor block flies out, material also can cause wearing and tearing to the upper and lower dish of rotor, for preventing the upper and lower adjustment debit of rotor bad, the method of existing employing can carry out in the surface coverage of the upper and lower dish of rotor the deflector changed, the connected mode of deflector offers screw thereon, adopt bolt directly to compress, this connected mode in use causes deflector point of attachment intensity step-down, easily ruptures.
Summary of the invention
The technical problem to be solved in the present invention is: the rotor block providing a kind of easy for installation, vertical shaft crusher that cost is low, can overcome the deficiencies in the prior art.
Technical scheme of the present invention is: a kind of rotor block of vertical shaft crusher, it comprises dish and rotor lower wall on rotor, rotor is provided with five groups of T-shaped material casting risers between dish with rotor lower wall, thrower head, counterpunch board, cutting plate and deflector, thrower head and counterpunch board are connected to material casting riser away from side, the center of circle, cutting plate is connected to the end of material casting riser near side, the center of circle, deflector to be fitted on rotor on dish or rotor lower wall, and in the region that deflector is connected in two pieces of material casting risers and cylindricality thrower head thereof, counterpunch board, cutting plate are formed.
The rotor block of above-mentioned vertical shaft crusher is, material casting riser is provided with the pressing table of extension with the contact side of deflector, and lower surface and the deflector end face of pressing table compress edge and contact.
The rotor block of above-mentioned vertical shaft crusher is, is provided with extension shoulder at the opposite side at compression edge, deflector upper surface, on rotor dish and rotor lower wall on extension shoulder be connected with puller bolt from side, the center of circle.
The rotor block of upper described vertical shaft crusher is provided with the backing strap groove of sinking.The thrower head of vertical shaft crusher, it comprises dish and rotor lower wall on rotor, rotor is provided with material casting riser between dish and rotor lower wall, is connected with thrower head at material casting riser away from side, the center of circle.
The thrower head of above-mentioned vertical shaft crusher is, thrower head is made up of cylindricality stub bar and connecting plate, end face and the cylindricality stub bar of connecting plate are tangent, two exhausting holes are offered at the contact area of material casting riser and thrower head, the connecting plate of thrower head offers positioning through hole, cylindricality stub bar offers screw, and material casting riser and thrower head are bolted.
The thrower head of aforesaid vertical shaft crusher is, the cylindricality stub bar of thrower head is connected with wear-resistant alloy layer.
The rotor block of aforesaid vertical shaft crusher is, counterpunch board is made up of the little counterpunch board split of three pieces of splayed structures, and the little counterpunch board of every block offers screw, and little counterpunch board is bolted on material casting riser.
The upper and lower two pieces of little counterpunch boards forming three pieces of little counterpunch boards of counterpunch board are provided with wear-resistant alloy layer.
Wear-resistant alloy layer is positioned at two corners outside counterpunch board.
Compared with the prior art, the present invention adopts the deflector of new construction, and this deflector eliminates the bolt presses structure of kidney slot, use the mode that skewback, limited block are fixing, the intensity of deflector can be made so significantly to be promoted, can prevent it from rupturing, affect service life.Contact because mounting means becomes face from point cantact, reduce, can cut down finished cost to the flatness requirement of part installed surface, the design of backing strap groove simultaneously decreases the part of non-effective work, reduces product weight, has saved goods cost.Connect bar type thrower head at material casting riser away from side, the center of circle simultaneously, the many advantages of bar type thrower head can be retained like this, thrower head is fixed by bolts on material casting riser, have changed mounting means, make the maintenance of thrower head simpler, convenient, fast with replacing, a difficult problem difficult to thrower head maintenance before solving.The cylindricality stub bar of thrower head is connected with wear-resistant alloy layer, and it is readjusted in alloy arrangement according to the concrete abration position of thrower head, and alloy can be cancelled in the position of not wearing and tearing, thus can reduce the production cost of thrower head.
The existing wearing piece counterpunch board for global design is processed into the structure of subregion formula, has the following advantages like this:
1, the structure taking partition group box-like, can carry out local replacing according to corresponding eroded area, and relatively existing overall structure can significantly reduce later maintenance cost and frequency of maintenance;
2, on the make, no longer comparatively large by mould during monoblock cast, the restriction of molten steel flow, cooling etc., considerably reduces the phenomenons such as pore, loose, crackle, improves castability preferably.
3, different counterpunch boards can be changed according to the difference of broken material, to be applicable to different materials or the broken requirement of material;
4, can have found region easy to wear is at work lower outside root, its position is adopted more higher leveled wearing piece, reduces frequency of maintenance, can reduce production cost simultaneously.
5, found by practice, three pieces of little counterpunch boards are processed into splayed structure, and more opposing parallel segmented has good intensity.
