Description
Technical field
The utility model application pulverized coal preparation industry is related to a kind of dynamic powder concentrator of screening coal dust.
Background technology
It needs to make after broken screening using industry of the coal dust as combustion medium, such as limekiln, power plant, coal dust
With.Coal dust screening is as shown in Fig. 1, and coal dust material is entered by the feed inlet 1 of dynamic powder concentrator, is dispersed in the air-flow of rising,
The air-flow that carry powder rises along charging cone 3, enters rotor mechanism 6 by guide vane 5, rotor mechanism 6 is filled in power
It sets and is rotated under 8 drive, guide vane 5 can make air-flow and powder granule generate rotary motion, be classified in advance, and collect
By rotor mechanism 6 throw away Lai coarse granule, the speed of air-flow can also be uniformly distributed in the height of entire rotor, by water conservancy diversion leaf
The coarse granule that piece 5 is collected is fallen in coarse powder cone 4, and being back to grinder by returning charge mouth 2 re-grinds.And fine powdered coal and gas
It flows into the middle part of rotor, coal powder collection device is sent to by discharge port 7.
Charging cone 3 is to protect the core component of coarse powder cone 4, is welded using compound wear-resisting steel plates, the heap outside steel plate
Weld one layer of wearing layer.Coal dust powder under the action of air-flow, to charging cone 3 have it is strong wash away rubbing action, due to built-up welding
Wearing layer abrasion-resistance is poor, and charging cone 3 can be caused abrasion broken hole, to cause coarse powder cone 4 to destroy, meeting when serious occur
Cause the damage of 6 body of entire rotor mechanism.Especially for charging cone 3 head, coal dust scouring force bigger, and head without
Any absolute construction uses build-up wear-resistant layer as charging cone, but head built-up welding is uneven, and service life is short, needs to spend
Take a large amount of time progress hand inspection and maintenance.
Invention content
The technical issues of the utility model is solved be：A kind of new composite wear-resistant layer and wear-resisting head are provided, charging is improved
The wear-resistant service life of cone mitigates the maintenance intensity of charging cone head.
Technical solution used by the utility model is：
The charging cone of coal dust powder concentrator is divided into conehead and cone two parts.Cone is welded by cone steel plate and conehead steel plate
It is integrated, including cone steel plate and the composite wear-resistant layer that is covered on cone steel plate.The conehead is connect with conehead steel plate, including
Wear-resisting head, the screw bolt and nut for connecting wear-resisting head；Wear-resisting head is made by high chromium cast iron material.
Further, composite wear-resistant layer includes wire netting and iron-filing mortar, and the wire netting and cone steel plate are welded and fixed company
It connects, skeleton booster action is played in composite wear-resistant layer, the iron-filing mortar is applied after mixing by cement, sand, iron filings, water
It is put on cone steel plate, becomes composite wear-resistant layer after dry.
Further, rubber seal is used in bolt head, protects bolt, be convenient for the disassembling, assembling and replacing of bolt.
The utility model has the beneficial effects that：Wear-resisting head wear resistence is excellent, easy for removal and installation, greatly reduces maintenance
Cost；Composite wear-resistant layer improves anti-coal dust scouring capability, and service life increases, while having saved material cost, easy for construction.

Specific implementation mode
Attached drawing 1 is the present embodiment structural schematic diagram, and charging cone 3 is divided into conehead and cone two parts, and attached drawing 2 is conehead office
Portion's enlarged drawing.Cone has cone steel plate 9 to be welded as a whole with conehead steel plate 10, and one layer of complex abrasion-proof is covered on cone steel plate 9
Layer, conehead include wear-resisting head 12, connect the bolt 14 and nut 11 of wear-resisting head 12.When necessary, using 13 sealing bolt head of rubber
Portion, rubber 13 has wear resistence, for protecting bolt head, is convenient for the disassembling, assembling and replacing of bolt.Wear-resisting head 12 uses rich chromium cast iron
It makes, rich chromium cast iron is the metal material for having good wear resistence.When wear-resisting head 12 abrasion to a certain extent, rubber can be removed
13, or nut 11 is directly unclamped, wear-resisting head 12 is replaced, periodic maintenance and replacement are conducive to.This mode for replacing wear-resisting head is big
The big maintenance work intensity for alleviating conehead, has saved time cost and material cost.
One layer of cementitious composite wearing layer 15 is covered on cone steel plate 9, which includes wire netting and iron filings
Mortar.Wire netting and cone steel plate 9 are welded and fixed connection, play skeleton booster action, iron-filing mortar by cement, sand, iron filings,
Water is applied to after mixing on cone steel plate, becomes composite wear-resistant layer 15 after dry, has good anti-coal dust souring,
Substantially increase the wear-resisting service life of cone.Compared with build-up wear-resistant layer, material is cheap, easy for construction, and service life is long, drop
Low production and maintenance cost.
