The specific embodiment
The utility model is described in further detail below in conjunction with specific embodiment.
Embodiment
Present embodiment provides a kind of double-shaft crusher, can be used on the scrap rubber material is handled, utilize extruding, shear action between the cutter, material is carried out fragmentation, can be used as the pre-treating technology equipment of the scrap rubber processing of multiple working procedure, shown in Fig. 1～4, this disintegrating apparatus comprises: frame 3, crushing chamber 8, drive unit 1, speed reduction gearing 2, two power transmission shafts 10, cutter and stationary knife groups 5; Wherein, drive unit 1 can adopt motor or engine; Speed reduction gearing 2 can adopt reductor, and drive unit can be connected with power transmission shaft 10 through shaft coupling 12 by speed reduction gearing 2;
Wherein, crushing chamber 8, drive unit 1 and speed reduction gearing 2 all are arranged on the frame 3; Crushing chamber 8 is provided with charging aperture and discharging opening, at the charging aperture place feed hopper 9 can be set, make things convenient for the material of auxiliary breaking to join in the crushing chamber 8, and can on feed hopper 9, install tire support device additional, can make broken tire material angle on request enter in the crushing chamber, improve broken efficient; Be provided with dump skip 11 at the discharging opening place, make things convenient for the material after the fragmentation to draw off; Outside the crushing chamber 8 screen cloth 4 can be set, screen cloth 4 covers on outside the crushing chamber 8 ringwise, and screen cloth 4 is driven in crushing chamber 8 inner rotary by the screen cloth drive unit 7 that is provided with on the frame 3;
Two power transmission shafts 10 are driven through speed reduction gearing 2 by described drive unit 1 respectively, can adopt two drive units and two speed reduction gearings, a drive unit drives a power transmission shaft through a speed reduction gearing, can guarantee power utilization rate height like this, simplify transmission system, and reduction breakdown rate, the front end of two power transmission shafts all extend in the crushing chamber 8, two power transmission shaft branches can be located at the both sides of crushing chamber 8, the front end of two power transmission shafts extend in the crushing chamber 8 from both sides respectively, the front end of two power transmission shafts be arranged in parallel in crushing chamber 8, be equipped with cutter on two power transmission shafts in crushing chamber 8, the mutual interlock of the knife edge part of two cutters forms movable cutter set 6; Cutter can adopt annular to have a plurality of cutters that pile up the blade of setting, the interlaced interlock of blade of the cutter on two power transmission shafts,
The crushing chamber 8 of movable cutter set 6 corresponding positions is provided with stationary knife group 5, and stationary knife group 5 can be arranged on the sidewall of crushing chamber 8 of movable cutter set 6 correspondences, is provided with interocclusal clearance between stationary knife group 5 and the movable cutter set 6.The cutting edge of carbide alloy can be set on the blade of the cutter of movable cutter set 6, stationary knife group 5, can increase the rigidity of cutter, strengthened to broken scrap rubber material sting shear force.
In the reality, an end that can make two power transmission shaft mounting cutters form movable cutter set 6 floats in crushing chamber 8, and the outer partial fixing of crushing chamber 8, asphyxia by external pressure on the chest and abdomen bearing in the time of can preventing that power transmission shaft is out of shape vertically, and then transmission is broken down.
Cutter on a pair of power transmission shaft of above-mentioned disintegrating apparatus rotates in opposite directions under drive unit, speed reduction gearing drive and forms movable cutter set, and close with the stationary knife assembly that is fixed on the crushing chamber sidewall, movable cutter set is rotated in opposite directions, engaged and broken and downward convey materials, turn over 180 ° after with interlock of stationary knife group and broken material once more.And, the rotatable screen cloth that outside crushing chamber, is provided with, feasible material less than the screen cloth mesh enters the next stage operation, and the blob of viscose of failing to sieve comes back to enter under the gravity effect in movable cutter set and the stationary knife group on the crushing chamber proceeds fragmentation.This disintegrating apparatus can to material movable cutter set that cutter forms, with the stationary knife group between be subjected to extruding greatly and shearing double action, diameter directly can be carried out fragmentation less than the damaged tire of 1100mm, whole tire can be broken for the following blob of viscose of 50 * 50mm, the tire commonly used of all size all can be broken, crushing chamber does not have material and overstocks, compact conformation, easy to operate, the production efficiency height.
With the damaged tire is example, when utilizing above-mentioned disintegrating apparatus to carry out fragmentation, damaged tire feed hopper is from the side entered into crushing chamber, it in the middle of the crushing chamber a pair of movable cutter set of rotation in opposite directions, damaged tire enters between the cutter of two movable cutter set, be squeezed and brought into downwards between the cutter, the gap of cutter is very little, and tire is sheared in the gap; Tire is subjected to these two kinds of effects and is torn, cuts off; Crushing chamber below is the discharging opening that opens wide, and crushing chamber is provided with the screen cloth of a rotation outward, and the tire by the moving knife fragmentation directly drops on the screen cloth; The diameter of screened port is bigger, and the material littler than sieve screen apertures fallen in the blowpit of its below, enters next process by belt feeder.The screen cloth that is rotated of the material by sieve screen apertures is not brought feed hopper (striker plate can be set) again on screen cloth, enters movable cutter set once more and carries out fragmentation; Fixedly install the stationary knife group on the crushing chamber sidewall, do not come off from cutter after by movable cutter set as material, then moving knife and stationary knife interact, and material is broken or material come off from moving knife.
In sum, the disintegrating apparatus of the utility model embodiment has following advantage: the adaptability height: energy is the tire of fragmentation from 200mm to 1100mm directly, also can broken contain the tire of steel wire; Power consumption is little, and output is big: because material percent of pass height, crushing chamber does not have the thing of overstocking down, so power consumption is little.Cutter is more, can give full play to its effect, and crushing is big; Easy to operate, the automaticity height: tire is delivered in the hopper by belt feeder, enters crushing chamber along hopper; Tool wear is little: because material is subjected to the extruding of cutter earlier, be shear action then, thus little to tool wear, reduce use cost.
The above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
