Description
Technical field
The present invention relates to pulverizers, more particularly, to a kind of rotor mill assembly.
Background technique
With China's economic development, sale of automobile increases increasingly, and increasing for waste tire produces environmental pressure therewith.According to
According to incompletely statistics, it is about 1,400,000 tons or more that the retired amount of waste tire is often only in China, and every year with 15% speed increase,
" black pollution " that more and more waste tires are formed brings threat to our living environment.Waste tire is carried out
Resource utilization not only solves environmental issue, also solves the demand of rubber raw materials.
A kind of coarse crusher for rubber is disclosed in the prior art, and application No. is CN201020688652.6, disclose powder
Broken equipment includes: rack, driving device, transmission device, grinding device and feed hopper.The tearing of the equipment utilization cutter group is made
With the rubber grain that will enter in crushing chamber device crushes.But it is unstable when machine at high speeds operation, noise is big, and does not have
There is denoising device；It will cause very big impact and damage to axis also without safeguard procedures in case of overload phenomenon.
Summary of the invention
To solve the problems, such as that vibration in the prior art, noise are big, lacking machine overload protection, the present invention provides a kind of new
Type rotor mill assembly.
The technical solution of the present invention is as follows:
A kind of crusher rotor assembly, including rotor, rotor drive, the overload protection for being set to rotor side
Device and the balancing device for being set to the rotor other side, balancing device include flywheel, are connected by flywheel shearing bolt with flywheel
The flywheel coupling covering plate, the connection rotor main shaft that connect couple the flywheel expansion sleeve of covering plate with flywheel.Flywheel, which considerably increases, to be turned
The rotary inertia of son, by this inertia force, in crushing process, rotor is steadily operated, and can effectively be reduced
Vibration and noise.
Overload protection arrangement includes the belt pulley connecting with rotor drive, with belt pulley by belt pulley shears bolt
Belt pulley coupling covering plate, the connection belt pulley of connection couple the belt pulley expansion sleeve of covering plate and rotor main shaft.When occurring
Carry situation when, rotor stops operating, and the coupling covering plate being connected by expansion sleeve with main shaft also stops therewith, and belt pulley by
It continues to operate due to the effect of inertia in the effect of driving device, flywheel.At this point, connection belt pulley and coupling covering plate,
Connection flywheel and the flywheel shearing bolt for coupling covering plate can be broken under the action of torsion, destroy belt pulley and main shaft,
The drive connection of main shaft and flywheel, belt pulley, flywheel dally, and protect main shaft, also ensure the stability of device.
Annular groove is provided on the screw rod circumferencial direction of belt pulley shearing bolt and flywheel shearing bolt.Section where making slot
For dangerouse cross-section, when torsion is excessive, screw rod can be broken at this section.So that belt pulley is dallied, plays mechanical protection
Effect avoids overload damage caused by main shaft and other adverse effects.
Overload protection arrangement further includes the security lock arrangement being arranged on flywheel coupling covering plate.After overload protection comes into force,
Belt pulley couples shield and flywheel coupling shield stops, and flywheel and belt pulley idle running, then is installed on flywheel coupling masking
Safety lock on plate is opened, and lock core pop-up touches the safety switch being installed on shield, makes system alarm and at the first time
Parking, thus plays the role of safeguard protection.
Rotor includes main shaft, knife rest, cutter, cutter pressing plate, cutter fixed plate and wear-resistant sleeve, and the cutter pressing plate passes through
Screw is connect with fixed plate；Slot is arranged in cutter pressing plate side, forms cutter holding tank with fixed plate junction.It can be convenient ground
Replacement, the maintenance of cutter are completed, and because rotor is overall structure, can satisfy intensity and toughness.
Main shaft, knife rest and fixed plate are welding.To make weldment reach the requirement of high tenacity, high abrasion, before welding, need
Heat treatment appropriate is carried out to main shaft, knife rest and fixed plate.
Cutter is uniformly arranged on main shaft circumferencial direction, and is anchored on knife rest by screw.Cutter is in main shaft circumferencial direction
Array distribution, guarantees cutter uniform force.
The extension elongation of cutter circumferentially is adjusted by the holding screw on the cutter pressing plate.
Cutter is parallelogram.Cutter manufacture cost is reduced, which turn over cutter upon wear
Turning 180 ° can reuse, and when cutter both ends are worn-out, can remove cutter and sharpen, the cutter after sharpening,
Identical as new knife performance, when installation sharpens cutter, the abrasion loss of cutter easily realizes benefit by the holding screw on cutter pressing plate
It repays, cutter is worth available maximum performance；Cutter preferably uses high-intensitive, high abrasion alloy material, by right
In the change of the shape of tool and material, effective tool life.
The angle [alpha] of cutter blade and main shaft meets 0 ° < α≤15 °, and rotor can ground when high speed rotation carries out crushing material
Uniform load is converted by impact load, rotor is enable steadily to operate, is generated when crushing material can also be effectively reduced
Noise.
Technical effect of the invention are as follows:
Vibration is reduced, noise is reduced, machine overload protection is provided for main shaft, and is shut down by safety lock, with ensuring equipment
Safe and stable, efficient operation.
