Description
Technical field
The utility model relates to the breaking chamber structure technology of centrifugal breaking type, especially has the centrifugal crusher of dark cavity configuration.
Background technology
At present, in the design of the centrifugal crusher breaking cavity of China, most chamber shape or do translation and material to be broken is in static state as model take moving jaw makes the performance of its function be subject to certain limitation.The flow regime of material in crusher chamber will be subject to the impact of mover Asynchrony characteristic, mainly is to be determined in the packed density of this layer by material bed height of drop and the material when the moving reciprocating swing one time that is in differing heights in the chamber.Each material bed fall time in the chamber, highly, packed density changes with the chamber is high.Take into full account these factors during the design of breaking cavity, it is more reasonable to design.Crusher chamber is the groundwork space of disintegrating machine, and whether the shape of crusher chamber is reasonable, directly affects the indexs such as equipment crushing effect, productivity ratio, energy consumption, wear liner, the ratio of reduction.Such as, existing crusher chamber is linear pattern basically, the width of ore discharge stone is determining granularity and the disposal ability of product to a great extent.After ore enters crusher chamber, but be subject to entering parallel band behind the impact grinding of mantle and the bump of the grinding between the ore.Enter the ore of parallel band, but continue to be subject on the one hand the impact grinding of mantle, constantly discharge on the one hand crusher chamber.Because parallel band is shorter, ore is few by the impact grinding number of times in parallel band, and mutual impact machine can reduce between the ore, so fine fraction content is low in the ore discharge, newborn fine fraction is less.This explanation has the part ore not have fine fragmentation just to discharge crusher chamber by parallel band.
Exist the reason of defects to be that mainly the stroke of ore materials in crusher chamber is shorter, after ore enters parallel band, be subject to the pinch shock between two conical surfaces, there is not in other respects restraining force, only has the obstruction between the material, so exist inevitably diffusion in shattering process, this just provides ore to have the chance of large-size at dispersal direction; On the other hand, the part ore is subject to the one-shot fragmentation in parallel band, does not reach the product granularity requirement; Simultaneously, ore has obtained larger kinetic energy before entering parallel band, some ore is not subject to the impact grinding crusher chamber that just flies out in parallel band, therefore, ore time of staying in crusher chamber is shorter, and the ore amount that holds in the crusher chamber is few, makes mutually extruding between the ore, friction, collision opportunity reduce, and just make some strips or flat ore can not get fragmentation and have just discharged crusher chamber.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of centrifugal crusher with dark cavity configuration, and the crusher chamber of this structure provides the stroke that is enough to guarantee material crushing.
Realize that goal of the invention measure of the present utility model is: upper rack is installed into hopper, discoid casing is installed in the bottom simultaneously, coaxial installation rotor in the casing, rotor bottom picks out main shaft, rotor hollow forms the axle feed bin, and rotor peripheries is installed impeller, and the rotor upper opening taps into hopper, form crusher chamber between casing inner wall and the rotor, discharging opening is arranged at the crusher chamber bottom in the casing.
The utility model has the advantage of, improve rotor-position, increase broken working space, effectively utilize the equipment centrifugal action, reach better crushing effect, and the raising thruput, have that crushing force is large, efficient is high, treating capacity is high, energy-conserving and environment-protective, action cost are low, easy to adjust, use the economic dispatch characteristics.
Description of drawings
Fig. 1 is the utility model structural representation.
Reference numeral comprises:
The specific embodiment
Below in conjunction with the embodiment explanation.
As shown in Figure 1, frame 1 top is installed into hopper 2, discoid casing 11 is installed in the bottom simultaneously, casing 11 interior coaxial installation rotors 12, rotor 12 bottoms pick out main shaft 7, and rotor 12 hollows form axle feed bin 6, rotor 12 peripheries are installed impeller 5, rotor 12 upper openings tap into hopper 2, form crusher chamber 4 between casing 11 inwalls and the rotor 12, and discharging opening 9 is arranged at casing 11 interior crusher chamber 4 bottoms.
Riser 14 is installed on the casing 11 inner edge walls in the crusher chamber 4, towards rotor 12 1 sides impact block 10 is installed at local riser 14, casing 11 inner edge end faces are installed backplate 13 in crusher chamber 4 simultaneously.
Especially, axle feed bin 6 upper openings project upwards near feed hopper 2, and simultaneously, crusher chamber 4 height are greater than axle feed bin 6.
Especially, impact block 10 tilts facing up towards the active side of rotor 12.
The utility model is by the transmission of motor, rotate by main shaft 7 rotor drivens 12, material in the feed hopper 2 enters axle feed bin 6 downwards through charging aperture 3, along with rotor 12 rotates, material in the axle feed bin 6 obtain centrifugal force and to around accelerate fast moving, through between the blade on the impeller 5, have and open jet material out, collision impact piece 10 towards behind the work side of rotor 12 to above bump behind the lower bullet with backplate 13 again, collide from jet material out again with rear, crushing efficiency significantly promotes therebetween, and the material after the fragmentation effluxes by discharging opening 9 downwards.
In the utility model, rotor 12 carries out the deep cavity shape design, and cavity strengthens; under the action of the centrifugal, material obtains abundant acceleration, and crushing effect is large; material movement locus height in equipment changes to some extent, and simultaneously, thruput improves about 30%; further improve output, thus long service life, and the epigranular of crushed product; reduced and followed the row load, and adopted the hydraulic pressure cavity clearing system, the hydraulic pressure insurance system; reduced downtime, reduced greatly maintenance rate and enhance productivity.
The utlity model has that crushing force is large, efficient is high, easy to adjust, use the characteristics such as economy, life-span are long, can be widely used in metallurgical industry, building materials industry, road work, chemical industry and the silicate industry, be applicable to broken medium or hard various ores and rock, such as iron ore, Copper Ores, lime stone, granite, quartzite etc.
