Description
Technical field
The utility model belongs to mechanical engineering technical field, the closed blender of specially a kind of electromagnetic drive.The stirring
Closed stirring of the machine for the poisonous and harmful raw material of chemical machinery industry.
Background technique
In chemical machinery industry, various materials are often stirred, manually stir time-consuming and laborious low efficiency, people just start
Mechanical mixers are researched and developed, thus mechanical mixers also just produce.
The mechanical mixers to come into operation at this stage are nearly all to drive agitating shaft, the agitating shaft other end with stirring motor
Spice is protruded into, and has stirring blade in stirring shaft end, stirring blade rotation is reachable to stir material under the drive of the motor
To good mixing effect.Since the transmission system of traditional agitating device still retains mechanically operated mode, in order to realize sealing
Property, designer installs seal member, such as rubber additional in the place that agitating shaft is in contact with the bung of agitator, on the periphery of agitating shaft
Rubber mat, sponge ring, Composite Material Seal Ring etc., but structure is complicated at this, poor reliability, need to often maintain, such as replacement rubber pad,
Supplemental lubrication agent etc. causes the pollution of stirring material in addition, lubricant is possible to fall into agitator.And in chemical machinery row
In industry, but often stir it is some it is poisonous and harmful have volatile material, traditional blender leakproofness is not achieved good close
Effect is sealed, is had a very important significance so designing the blender that a kind of structure is simple, leakproofness is excellent.
Utility model content
In view of the deficiencies of the prior art, the technical issues of the utility model intends to solve is to provide a kind of the close of electromagnetic drive
Close blender.The blender uses for reference the working principle of motor, blade of stirrer oneself rotation may be implemented, without having with outside
Mechanical Contact, excellent sealing function can be reached by not needing complicated sealing device at work, save cost and sealing
Effect is original more preferable compared to relatively, substantially increases reliability.
The technical solution that the utility model solves the technical problem is to provide a kind of closed blender of electromagnetic drive,
Including cover, agitator, cover and agitator constitute confined space, it is characterised in that the blender further include threephase stator around
Group, cage rotor and multiple supporting mechanisms, the agitator is interior to support fixed cage rotor by supporting mechanism, turns with mouse cage
Multiple threephase stator windings are uniformly distributed on the agitator outer wall of sub- corresponding height；Master is installed on the axis of the cage rotor
Axis, main shaft and cage rotor using transmitting power by the way of key connection, main shaft lower end pass through cage rotor lower end center and
The bottom of agitator is connected and fixed by bearing；Main shaft positioned at cage rotor lower end central upper is equipped with the shaft shoulder, passes through axis
Shoulder fixes stirring blade on main shaft；
Multiple supporting mechanisms are evenly arranged in the marginal position of cage rotor lower surface along the circumferencial direction of cage rotor, more
The upper surface of a supporting mechanism and the lower surface of cage rotor are in rolling contact, and the lower end of multiple supporting mechanisms is fixed on agitator bottom
On face.
Compared with prior art, the utility model has the beneficial effects that:
1. structure is simple: the utility model blender realizes the biography without Mechanical Contact using the principle of electromagnetic driven torque
It is dynamic, the cage rotor rotation in electromagnetic drive (not needing transmission shaft) agitator is directlyed adopt, the cover of agitator is without design
At original labyrinth, only cage rotor need to be integrally put into agitator, then be covered with cover, sealing can be realized,
Greatly reduce the structural complexity of blender.
2. good reliability: it is hermetically sealed that the utility model blender may be implemented no dead angle, i.e., inside blender with it is extraneous every
Exhausted effect is fine, compared to punching on cover more originally, for the kind of drive that agitating shaft protrudes into, without beating on cover here
Hole, after placing stirring material, covering cover can be realized sealing stirring, can have when stirring is poisonous and harmful volatile liquid
The safety of the protection operator of effect.
3. high-efficient: having abandoned original machine driving, eliminated the frictional force between original agitating shaft and bung, improved
Transmission efficiency.Because blender originally is all to drive agitating shaft by motor, then agitating shaft is protruded into inside blender, into
Row stirring, wherein energy loss part includes: that the transmission of (1) motor and agitating shaft has energy loss (2) cover of part
On have a hole so that agitating shaft protrudes into blender, will use bearing (ball) cover, bearing, sealing felt collar at the hole and be sealed, this
Sample one will also result in partial frictional, off-energy.In this way, which transmission efficiency will be lower.And the blender of the application is
It drives stirring blade to rotate using electromagnetic force, eliminates the machine driving of original complexity, greatly improve the efficiency.
