Description

Jaw crusher

Technical field

Utility model is to the broken improvement with jaw crusher of material, relate in particular to a kind of can direct broken viscous material, the big jaw crusher of broken reducing scope.

Background technology

It is broken that jaw crusher is called for short Hubei Province, though multiple version is arranged, the basic principle structure mainly comprises broken with fixed moving Hubei Province plate 2 of deciding Hubei Province plate 1 and swing attrition crushing as shown in Figure 1.Operation principle: periodically break (folder) material that minces to decide Hubei Province plate swing by moving Hubei Province plate, the dispatch of broken material then is to leave when deciding Hubei Province plate and swinging round about at moving Hubei Province plate, deadweight moves downward by material to produce big gap, each the periodic wobble motion of moving Hubei Province makes material be subjected to once crushing, and downward dispatch one segment distance, material is at last outside two Hubei Province plate lower end discharge gate discharge machine.Jaw crusher, have simple in structure, the ratio of reduction is big, reliable operation, keep in repair easy, running cost economic dispatch characteristics are widely used in numerous industries such as mine, smelting, building materials, cement, chemical industry, coal, refractory material and pottery, do material in broken and in small, broken bits, broken compression strength generally be no more than the various soft or hard materials of 320 MPas.

Yet because broken Hubei Province plate upwards do not have any motion at the oscillating motion axis, causing broken material is to be swung away from by moving Hubei Province to decide Hubei Province generation spacing, according to the gravity discharge that falls naturally gradually.Decision can only broken hard and non-sticking dryness material thus, and can not broken wet viscous material (viscous material easily adhere to Hubei Province plate can not fall discharge), and two Hubei Province plate bottom gap also can not do very carefully (main consider stop up), cause the primary fragmentation particle size range less relatively, can not be directly used in and be crushed to granule, to smelt ore reduction is example: the mineral material need usually broken through Hubei Province, circular cone is broken, broken three grades of fine powder, causes broken total energy consumption higher.Main two big shortcomings are broken in above-mentioned formation Hubei Province, particularly can not broken viscous material, cause the viscous material fragmentation, must dry by the fire or dry, make viscosity reduce the back fragmentation significantly, bring very burden for the viscous material fragmentation, cause the fragmentation of viscous mineral material to become global problem, so far above-mentioned defective is unresolved, and the improved place of being worth is arranged.

The utility model content

The utility model purpose is to overcome above-mentioned the deficiencies in the prior art, provides a kind of and can overcome the broken two big shortcomings in existing Hubei Province, and primary fragmentation change of size scope is big, and the jaw crusher of the direct broken viscous material of energy.

The utility model purpose realizes, the main improvement is to have the broken carrier bar of revolution that moves, decides to coat outside the plate of Hubei Province similar tank track of jaw crusher now, thereby drive material by the gyration of turning round broken carrier bar and move down discharge, become former dependence gravity blanking and drive blanking into broken carrier bar revolution, overcome the deficiencies in the prior art, not only can direct broken viscous material, and can make two Hubei Province plate bottom gaps do lessly, enlarge primary fragmentation reducing scope, realized the utility model purpose.Specifically, the utility model jaw crusher comprises and decides Hubei Province plate and the moving Hubei Province of swing plate that it is characterized in that moving, decide Hubei Province plate has moving runner in two ends up and down, is surrounded by the broken carrier bar of revolution hard outward.

Utility model is said:

Move, decide Hubei Province plate, support mainly as the broken carrier bar of revolution, enable between the carrier bar face, to form extruding force (prevent to turn round broken carrier bar indent and lose attrition crushing power), because of moving, decide Hubei Province plate major function is to set off the anti-indent distortion of carrier bar, directly do not contact broken material, get final product, can consider the wearability of material so only need rigidity to support, reality does not almost have former broken Hubei Province plate function yet, and this patent is just used its title.The swing of moving Hubei Province can be adopted prior art cam crank form, or other known swings or rotary oscillation mode, for example eccentric shaft swing.

The two ends moving runner, the revolution that is mainly the broken carrier bar of revolution provides power and helical pitch, makes broken carrier bar can produce gyration.Support carrier bar gyration mode that multiple concrete form can be arranged, chain wheel drive for example, this belongs to prior art.

The broken carrier bar of revolution hard, similar tank track on the version can gyration, the carrier bar hard, mainly from broken angle, its hardness is greater than and is minced, use always and can adopt the antifriction metal (AFM) plate, also do not get rid of other materials certainly, select according to broken material character as prior art.The leaf chain structure mainly is to consider from broken angle, if only be the narrower chain of width, then can reduce crushing effect.Broken carrier bar, length direction better is en-block construction, helps turning round the drives structure design; Carrier bar can be an optic panel, also can be the non-shiny surface, particularly tooth plate structure of band sags and crests or bastard, both can strengthen carrier bar intensity, the skidding of hard material in the time of preventing fragmentation again, tooth plate wherein better is teeth groove and gyration axially parallel, more helps the broken material automatic discharge.Certainly carrier bar can also be a surface roughness, is used for more broken granularities and requires the homogeneous material fragmentation.Each thickness of link plates according to broken material hardness, can change between 5-10cm; The carrier bar width is preferably 10-30cm.

In addition, for preventing that broken material from entering carrier bar and causing jam, improve operation stability, reduce clearing times, carrier bar is in abutting connection with both sides, respectively there is alternate not penetrating oblique concave surface raker tooth embedded structure at a kind of more preferably back side in abutting connection with both sides, so both having satisfied carrier bar, to go to the driving wheel side face curved, can guarantee that again adjacent carrier bar what adjacent side, front, position (plane of disruption) in office do not have broken material and embed the slit.

The utility model jaw crusher, with respect to prior art, owing to adopt moving, decide Hubei Province plate and coat the broken carrier bar of revolution outward, former jaw crusher crumbling method and function have not only been kept, and because crushing shell is the revolution chain structure, can drive material whereabouts (material moves down by the broken carrier bar of revolution and drives), originally can only rely on material gravity to fall naturally thereby overcome, cause the material haftplatte can not broken viscous material, and primary fragmentation change of size scope is little, can not directly be broken into granule (the too small meeting in gap results in blockage) two big long-term existence, and unsolved defective, enlarged the jaw crusher scope of application, broken particle size range also obtains increasing, and is not very high material of requirement to some final fineness, can put in place by primary fragmentation, directly obtain fine grained, not only shorten crushing circuit, and reduced broken total energy consumption, as calculated at least can be energy-conservation more than 50%.The utility model jaw crusher turns round broken carrier bar and interior the support is to constitute this patent the most basic two big distinguishing characteristics, is different from existing jaw crusher.

Below in conjunction with an exemplary embodiment; utility model essence is further understood in exemplary illustration and help; but the embodiment detail only is for utility model is described; do not represent utility model design whole technical schemes down; therefore should not be construed as the total technical scheme of utility model is limited; some are In the view of the technical staff; the unsubstantiality that does not depart from the utility model design increases and/or change; for example change or replace, all truely use novel protected scope so that technical characterictic with same or similar technique effect is simple.
