Description
Technical field
The present invention relates to pulverizer, especially relate to a kind of rotor mill and always become.
Background technology
Along with China's Economic development, sale of automobile increases increasingly, and increasing of junked tire creates environmental stress thereupon. According to incomplete statistics, China is often only the retired amount of junked tire and is about more than 1,400,000 tons, and every year with 15% speed increase, " black pollution " that more and more junked tires is formed brings threat to our living environment. Junked tire is carried out recycling and not only solves environmental issue, also solve the demand of rubber raw materials.
Disclosing a kind of coarse crusher for rubber in prior art, its application number is CN201020688652.6, discloses disintegrating apparatus and comprises: frame, drive unit, transmission mechanism, shredding unit and hopper. This equipment utilization set of knives tear effect, the rubber grain that enters in crushiing chamber device is pulverized. But unstable when this machine runs at a high speed, noise is big, and does not have denoising device; If there is overload phenomenon, there is no safeguard procedures yet, axle can be caused very big impact and infringement.
Summary of the invention
Shake for solving in prior art, noise is big, lack the problem of machine overload protection, and the present invention provides a kind of novel rotor mill and always becomes.
The technical scheme of the present invention is:
A kind of novel rotor mill always becomes; comprising rotor, rotor drive, the overload protection arrangement being arranged at rotor side and be arranged at the equilibrator of another side of rotor, equilibrator comprises flywheel and flywheel and shears, by flywheel, flywheel coupling covering plate that bolt is connected, is connected rotor main shaft with flywheel and is coupled the flywheel swelling cover of covering plate. Flywheel considerably increases the rotational inertia of rotor, and by this mass force, in crushing process, rotor is able to steady running, and can effectively reduce vibrations and noise.
Overload protection arrangement comprises the belt pulley being connected with rotor drive and shears the belt pulley coupling covering plate that bolt is connected, the belt pulley swelling cover connecting belt pulley coupling covering plate and rotor main shaft with belt pulley by belt pulley. When there is overload situations, rotor stops rotating, and the coupling covering plate being connected with main shaft by swelling cover is also stopped thereupon, and belt pulley will remain in operation due to the effect of inertia due to the effect of drive unit, flywheel.Now; the flywheel shearing bolt of connection belt pulley and coupling covering plate, connection flywheel and coupling covering plate can rupture under the effect of torsion, destroys the drive connection of belt pulley and main shaft, main shaft and flywheel, and belt pulley, flywheel all dally; protect main shaft, also ensure that the stability of device.
Belt pulley is sheared and is had annular groove on the screw rod circumferential direction of bolt and flywheel shearing bolt. Making cross section, groove place be dangerous section, when torsion is excessive, screw rod can rupture at this section. Belt pulley is dallied, plays the effect of mechanical protection, avoid damage and other disadvantageous effects that main shaft is caused by overload.
Overload protection arrangement also comprises the security lock arrangement being arranged on flywheel coupling covering plate. After overload protection comes into force; belt pulley coupling masking shield and flywheel coupling masking shield stop; and flywheel and belt pulley idle running; the safety lock being then installed on flywheel coupling masking shield is opened; lock core ejects; touch the safety switch being installed on shield cap, make system alarm and stop in the very first time, thus play the effect of safeguard protection.
Rotor comprises main shaft, knife rest, cutter, cutter pressing plate, cutter retaining plate and wear-resistant sleeve, and described cutter pressing plate is connected with retaining plate by screw; Cutter pressing plate side arranges groove, and itself and retaining plate junction form cutter and hold groove. Can conveniently complete replacing, the maintenance of cutter, and because rotor is one-piece construction, it is possible to meet intensity and toughness.
Main shaft, knife rest and retaining plate are welding. For making weldment reach the requirement of high tenacity, high abrasion, before welding, it is necessary to main shaft, knife rest and retaining plate are carried out suitable thermal treatment.
Cutter is evenly arranged on main shaft circumferential direction, and by screw fastening on knife rest. Cutter, in the distribution of main shaft circumferential direction array, ensures cutter uniform force.
Cutter is adjusted by the tightening screw on described cutter pressing plate in extrusion circumferentially.
Cutter is parallelogram. Reduce cutter manufacture cost, this parallelogram sturcutre makes cutter upon wear, overturn 180 ° can reuse, when wearing and tearing all in cutter two ends, cutter can be pulled down and carry out sword mill, the cutter after sword grinds, identical with new cutter performance, when installing sword knife milling tool, the abrasion loss of cutter easily realizes compensating by the tightening screw on cutter pressing plate, and cutter is worth and can be played to greatest extent; Cutter preferably adopts the alloy material of high strength, high abrasion, by the change for cutter shape and material, effectively extends cutter life.
The angle [alpha] of cutter blade and main shaft meets 0 °, and < α≤15 °, impact load can be converted into even load in ground when high speed rotating carries out crushing material by rotor, makes rotor be able to steady running, it is also possible to the noise produced when effectively reducing crushing material.
The technique effect of the present invention is:
Reduce vibrations, reduce noise, be main shaft machine overload protection is provided, and shut down by safety lock, with ensuring equipment safety, stable, run efficiently.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described:
As shown in accompanying drawing 1-5, rotor mill always becomes, and comprises rotor, rotor drive, the overload protection arrangement being arranged at rotor side and is arranged at the equilibrator of another side of rotor.Equilibrator comprises flywheel 15 and flywheel 15 and shears, by flywheel, flywheel coupling covering plate 13 that bolt 14 is connected, is connected rotor main shaft 1 with flywheel and is coupled the flywheel swelling of covering plate 13 and overlap 12. Overload protection arrangement comprises the belt pulley 8 being connected with rotor drive and shears the belt pulley coupling covering plate 10 that bolt 9 is connected, the belt pulley swelling cover 11 connecting belt pulley coupling covering plate 10 and rotor main shaft 1 with belt pulley 8 by belt pulley. Rotor comprises main shaft 1, knife rest 2, retaining plate 3, cutter 4 and cutter pressing plate 5, and knife rest 2 is set on main shaft 1, and retaining plate 3 is arranged in the card groove of knife rest 2, and main shaft 1, knife rest 2 and retaining plate 3 are fixed installation; Cutter pressing plate 5 is connected with retaining plate 3 by tightening screw 7; Cutter pressing plate 5 side arranges groove, and itself and retaining plate 3 junction form cutter and hold groove. Cutter 4 is evenly arranged on main shaft 1 circumferential direction, and by being anchored on knife rest 2 closing screw 6. Cutter 4 is parallelogram.
