Description

The single roller swinging of binary channels high energy crusher

(1) technical field

The utility model relates to a kind of disintegrating apparatus, the single roller swinging of particularly a kind of binary channels high energy crusher, it is applicable to that compression strength such as all kinds of ores, clinker, industrial chemicals, lime stone, refractory material, quartz sand, glass, pottery, corundum are lower than the following material grinding operation of 350Mpa.

(2) background technology

Disintegrating machine type in the market is a lot, and jaw crusher, hammer mill, cone crusher, oppositely rolling roller crusher or the like are arranged.With regard to jaw crusher, from technical standpoint, belong to the typing old product, do not have big breakthrough on the structure, efficient is lower, ratio of reduction smaller defect but it exists; Then there is a problem that tup is easy to wear in hammer mill, and producing cost is higher; For cone crusher, though discharging-material size is even substantially, controllable granularity is built in less than 25 millimeters, but this size does not satisfy the requirement of present grinding process, moreover the adjusting play is pretty troublesome, if very do not fall into ironware, deal with quite thornyly, moreover equipment manufacturing cost is high too; Oppositely rolling roller crusher can be guaranteed uniform discharging-material size, but requires less to material size.Therefore, if with below the material primary fragmentation to 20 of 120-220 millimeter millimeter, above-mentioned disintegrating apparatus all can not meet the demands.

(3) summary of the invention

A kind of new type crushing machine that the purpose of this utility model designs at existing weak point in the above-mentioned prior art just, this machine is reasonable in design, adopt binary channels, single roller rotational structure, surfacing has the high alloy high-abrasive material on the breaker roll, has that energy-efficient, the ratio of reduction is big, the characteristics of mill part long service life.

The purpose of this utility model realizes by following scheme: the single roller swinging of this binary channels high energy crusher comprises body, be positioned at the breaker roll that body is connect by bearing by main shaft, tooth plate seat and be fixed on arc tooth plate on the tooth plate seat, wherein: two arc tooth plates of determining are symmetricly set on the breaker roll both sides, main shaft is an eccentric shaft, its two ends are held in place on the two end wall panels bearing block outward of body by bearing respectively, and the two ends at eccentric main axis is equipped with flywheel and belt pulley respectively, two tooth plate seat tops are suspended on respectively on two horizontal axis tams that are positioned at breaker roll two upper lateral parts, the two ends of two horizontal axis tams frame respectively are placed on two end wall panels of body, form broken passage between breaker roll and the both sides arc tooth plate, the lower end edge of breaker roll and both sides arc tooth plate is discharge gate.

In the utility model, breaker roll and eccentric main axis connect by radial roller bearing; The bottom of two tooth plate seats is respectively equipped with the adjustment safeties, and the width of broken passage discharge gate can be regulated by adjusting safeties; These adjustment safeties are made of screw rod, screw bolt seat and safety bolt, the rear portion of screw rod is connected on the body framed side wallboard by screw bolt seat and safety bolt, both can adjust the gap on arc tooth plate and breaker roll surface by this device, can play the security insurance effect again, when falling into ironware or super scope hard ware material in the broken passage, arc tooth plate will be given bigger thrust of screw rod by the tooth plate seat, when its thrust exceeds the limit holding capacity of safety bolt, this safety bolt will break, the tooth plate seat will retreat this moment, thereby play safety effect.

Lower end at two tooth plate seats is respectively equipped with hook, and this hook is connected with the take-up device of being made up of the pull bar that is coated with spring on it, and the rear portion of pull bar is arranged on the body framed side wallboard, and its effect is further tooth plate seat bottom to be strained and fixed, and reduces vibration.

Axle head at corresponding two horizontal axis tams is connected with an arm-tie respectively, and two arm-ties all are located at the outside of two end wall panels of body, makes whole machine body more fastening stable; Bearing block is installed on the outer bedplate vertical with wallboard of body wallboard.

Operation principle of the present utility model is: the core members of this disintegrating machine be one be contained on the eccentric shaft and and eccentric shaft the breaker roll of relative motion (revolution and swing) and two up big and down small broken passages of the broken tooth plate composition of the arc that is arranged on its both sides are arranged, during work material from it the batch meter of portion enter two broken passages, by means of the rotation of breaker roll on the eccentric shaft and swing and the double action that produces extruding, splitting makes material alternately obtain fragmentation in two broken passages, its qualified products are discharged continuously from the discharge gate of two side lower parts.Two broken passages of this machine are that the camber line shape by the band saw profile of tooth constitutes, its outlet is unblocked, bulk materials falls after crowded broken at the feeder connection place, middle and lower part at its passage forms the higher multilayer dose of filling rate, the energy that motor transmits acts in the middle of the material by roller, it is broken that the broken complementary energy that produces is carried out once more, contacts with the direct of work package thereby reduce material, improves energy utilization ratio the service life of prolongation wear-out part.The eccentric throw of this machine tradition is confidential much smaller, and rotating speed is high slightly, therefore turn over and have good ultra-fine fragility energy, the vibration of machine is less simultaneously, breaker roll is swung with moving of eccentric shaft eccentric position, fragmentation is operated in its passage to be done, breaker roll is connected with the biserial radial roller bearing of eccentric shaft by the band sleeve, therefore when breaker roll with the motion of eccentric shaft during broken material, roll surface will produce with the slow-speed of eccentric shaft switched in opposite moving, so, will reduce the wearing and tearing of material pair of rollers, effectively improve the service life of wearing piece.

The advantage that the utility model is compared with prior art possessed is:

(1), thereby the utilization rate of power source is not fully exerted because this machine has changed the single pass broken theory of disintegrating machine in the past, all actings that promptly moves forward and backward, so energy-saving effect is remarkable, the general disintegrating machine of energy consumption reduces by 50%.

(2) on designing, be conceived to bigger material admission passage, and the less and non-resistance of the outlet gap of passage, thereby make this machine that the bigger ratio of reduction (ratio of reduction i=15-60) be arranged.

(3) breaker roll adopts high alloy new material and surfacing new technology, and be connected with rolling bearing between breaker roll and the eccentric shaft, thereby the slow-speed that breaker roll can be done reduce friction is moving, make roll surface wearing more even, service life of wearing piece thereby be multiplied, be prior art 3----5 doubly.
