Description

A kind of impact breaker that is equipped with scattering impact plate
Technical field
The invention belongs to the disintegrating machine technical field, more specifically say a kind of impact breaker that is equipped with scattering impact plate.
Background technology
Impact breaker utilizes the rotor of High Rotation Speed that the material of knocking down in the crusher chamber is produced high speed impact, and materials casting to counterpunch board, material is fallen by gravity and bounce, but the rotor of High Rotation Speed drives bar tangentially clashes into material again, material is thrown to another piece counterpunch board, material is by further broken, then again from the counterpunch board bar that rebounds, repeat said process, in this process, be subject to the strike of bar, impact and the material collision each other of counterpunch board owing to material, material constantly produces the crack, until loose pulverizing.When raw meal particle size during less than the discharge slit between counterpunch board and the bar, just drawn off crusher chamber.Yet the shortcoming of impact breaker maximum is that bar and counterpunch board are easy to wear especially, especially broken hard ore, and it is even more serious to wear and tear, and needs often to change.But it still has the value of existence, and namely its advantage is to have good shaping feature, and selecting impact breaker in the reality mainly is the shaping feature that utilizes it.
Because the broken Shape of impact plate of prior art counterattack is solid flat board, the material counterattack is " reflecting in order shape ", namely strike back logistics and concentrate on a direction, be unfavorable for abundant bump and polishing between material and the material, the direct result of more than bringing is that fragmentation and shaping effect are all undesirable.
Summary of the invention
The object of the invention is to promote fragmentation and the shaping effect of prior art impact breaker, a kind of scattering impact plate is provided, it can make material produce the crushing effect of scattering back-beating, thereby significantly improves fragmentation and the shaping efficient of impact breaker.
In order to reach above purpose, the present invention is achieved through the following technical solutions: a kind of impact breaker that is equipped with scattering impact plate, comprise frame, and frame is provided with feeding-passage, counterpunch board, angle regulator, rotor assembly and discharge gate; The week of rotor assembly upwards is provided with bar, forms crusher chamber between rotor assembly and the counterpunch board, and counterpunch board one end directly is hinged on the frame, and the other end is located on the frame by angle regulator; It is characterized in that, be arranged to the mesh network pore structure on the described counterpunch board.
Core technology of the present invention is: make the broken Cracking Mechanism of prior art counterattack become " reflecting in order shape " counterattack and be " disordered chain shape " counterattack, and allow material prolong the holdup time in crusher chamber.
Remarkable result of the present invention is in shattering process, the bump between material and the material, the polishing probability is higher, number of times is more and more abundant effectively, thereby promote counterattack broken fragmentation and shaping feature.
Counterpunch board is set to the mesh network pore structure, and it brings following benefit:
(1) with the counterpunch board of mesh network pore structure so that material rebounds unordered in crusher chamber, form a kind of scattering phenomenon, so that each corner angle of material are impacted polishing mutually, can access well pin, the sheet problem of finished product material and to solve, the specification item matter of acquisition is very high like this.
(2) the mesh network pore structure be so that after material forms scattering phenomenon, can also make between material and the material and mutually touch, and in the time of further in small, broken bits, can reduce machine loss again, reduces cost.
(3) in the counterpunch board manufacture process, carry out the quenching heat treatment operation, namely be immersed in the water quick cooling heating to red-hot crushing wall, to reach the purpose of quench hardening.The present invention is provided with thickly dotted reticulated cell group with counterpunch board, has greatly increased the contact area of quenching counterpunch board and water, greatly is conducive to the quenching degree in the quenching technical, thereby has strengthened hardness, wearability and the service life of counterpunch board.
As preferably, this network structure be by the hexagon mesh form cellular.
Cellular is structure the most special in the network structure, and it not only has cancellated all characteristics, and its easier realization is at random, nondirectional shearing-crushing power, makes it have larger broken snap-in force.In addition, in all network structures, in the situation that forms the formed objects area, the hollow ratio of cellular formation larger (hollow ratio=hollow area/gross area), it has strengthened " split broken, folding is broken, squeeze broken " etc. crushing function, more be conducive to improve crushing efficiency.
As preferably, described mesh is through hole.
Through hole is the first-selected embodiment of mesh design of the present invention, and wherein the specification material less than through-hole diameter can withdraw from fragmentation in advance, so that fragmentation can transition.
As the alternative of such scheme, described mesh is blind hole.
Reaching under the key property prerequisite of the present invention, blind hole also is the embodiment that can be used as mesh design of the present invention.
