Upper mechanical stirring, with being continuously increased to sealing requirements, lower magnetic agitation has gradually replaced mechanical stirring, becomes mainstream
Trend, either foreign countries or home brands, lower magnetic agitation mostly use contact to design greatly now, and existing axial rub also has
Radial friction uses such design for large tank, is axially and radially intended to bear very big frictional force and itself weight
Power, therefore it is easy to appear phenomena such as rubbing abnormal sound or ceramic bearing damage in use, it is even external existing at present
Floated design, due to its design and design feature, use scope is limited, and can not change agitating paddle according to customer demand
Leaf form, is unable to satisfy that client is multiple batches of, multi-item production requirement.Furthermore the impeller of current lower magnetic stirring apparatus and outer magnetic
Steel is fixed on one, and end face magnet steel, end face magnet steel and the end face magnet steel phase being located at the top of isolation cover are also equipped at the top of impeller
Mutually repel, although phenomena such as being able to solve existing friction abnormal sound or ceramic bearing damage, to replace impeller according to customer requirement
When, then it needs together to unload the end face magnet steel on entire outer steel, impeller, operation is very troublesome, cannot be according to customer demand
Using the impeller of customization form.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the prior arts, provide it is a kind of it is compact-sized, realize no end face
Friction transmitting power can use the impeller of customization form according to customer demand, can do the lower magnetic suspension mixing plant turned.
The purpose of this utility model is achieved through the following technical solutions: a kind of lower magnetic suspension mixing plant, it includes electricity
Machine, the speed reducer being sequentially arranged from lower to upper and motor support base, the outside of the motor support base are installed with ring flange, ring flange
Top is installed with isolation cover, and end face lower magnetic steel and bearing inner race are provided at the top of isolation cover, and the motor is connect with speed reducer,
The output shaft of speed reducer is connected with the shaft coupling being inserted into motor support base, and coupling sleeve, coupling sleeve are provided at the top of shaft coupling
Protrude into isolation cover, interior magnet steel is provided on the outer wall of coupling sleeve；The bearing inner race is arranged with bearing outer ring, bearing outer ring
Outside be installed with rotary sleeve, the outside of rotary sleeve is provided with impeller, and wheel hub of the impeller through screw through impeller is fixed on rotation
It puts on, the bottom of rotary sleeve offers cavity, and cavity covers in outside isolation cover, and the bottom of cavity is provided with end face upper magnetic steel, end
Face upper magnetic steel and the opposed setting of end face lower magnetic steel are provided with outer steel on the inner wall of cavity, and outer steel and interior magnet steel are opposed
Setting.
Bearing is provided in the motor support base.
The shaft coupling is installed in bearing.
The outside of the isolation cover is provided with mounting plate.
The bearing outer ring is set to the middle part of end face lower magnetic steel.
The utility model has the advantage that
(1) power is transmitted by magnetic coupling, is separated outer steel and interior magnet steel using isolation cover, radial magnetic field and end face
Magnetic field all has Automatic-centripetal physical characteristic, and bearing inner race and bearing outer ring can be made to form stable spacing, while making interior magnetic
Steel and outer steel form stable spacing, to realize no end face friction transmitting power, effectively prevent because of the bring that rubs
The pollution risk of abnormal sound and abrasive dust to liquid in tank body.
(2) designed using new-type magnetic suspension structure: end face upper magnetic steel, which forms end face magnetcisuspension with end face lower magnetic steel, is isolated, and increases
It is isolated the magnetic suspension force in face, the liquid because being stirred effectively is overcome and stirring self gravity is excessive the friction of isolation face occurs
Phenomenon.
(3) impeller is fixed on rotary sleeve through screw through the wheel hub of impeller, when replacing impeller shape according to customer requirement
When formula, only need to back-out screw directly can unload impeller from rotary sleeve, without unloading rotary sleeve, outer steel and end face magnet steel
Under, therefore when not changing outer magnetic structure, impeller can use customization form according to customer demand, effectively overcome existing
The not replaceable drawback of structure further increases flexibility and diversity that product uses.

Specific embodiment
The utility model is further described with reference to the accompanying drawing, the protection scope of the utility model be not limited to
It is lower described:
As shown in Figure 1 and 2, a kind of lower magnetic suspension mixing plant, the speed reducer that it includes motor 1, is sequentially arranged from lower to upper
2 and motor support base 3, the outside of the motor support base 3 be installed with ring flange 4, the top of ring flange 4 is installed with isolation cover 5, isolation
The top of cover 5 is provided with end face lower magnetic steel 6 and bearing inner race 7, and the motor 1 is connect with speed reducer 2, the output shaft 8 of speed reducer 2
Be connected with the shaft coupling 9 being inserted into motor support base 3, the top of shaft coupling 9 is provided with coupling sleeve 10, coupling sleeve 10 protrude into every
From in cover 5, being provided with interior magnet steel 11 on the outer wall of coupling sleeve 10；The bearing inner race 7 is arranged with bearing outer ring 12, bearing outer ring
12 outside is installed with rotary sleeve 13, and the outside of rotary sleeve 13 is provided with impeller 14, and impeller 14 is through screw 15 through impeller 14
Wheel hub is fixed on rotary sleeve 13, and the bottom of rotary sleeve 13 offers cavity 16, and cavity 16 covers in outside isolation cover 5, cavity 16
Bottom be provided with end face upper magnetic steel 17, end face upper magnetic steel 17 and the opposed setting of end face lower magnetic steel 6 are set on the inner wall of cavity 16
It is equipped with outer steel 18, outer steel 18 and the opposed setting of interior magnet steel 11.
Bearing 19 is provided in the motor support base 3, the shaft coupling 9 is installed in bearing 19.Outside the isolation cover 5
Portion is provided with mounting plate 20.The bearing outer ring 12 is set to the middle part of end face lower magnetic steel 6.
The course of work of the utility model is as follows: mounting plate 20 being mounted on to the bottom of large tank, by impeller 14
It is placed in large tank with rotary sleeve 13, starts motor 1, the torque of motor 1 passes to shaft coupling 9 after the deceleration of speed reducer 2, joins
Axis device 9 rotates, and shaft coupling 9 drives the interior magnet steel 11 on coupling sleeve 10 to make rotating motion again, in interior magnet steel 11 and outer steel 18
Outer steel 18 is driven to make rotating motion under coupling, so that rotary sleeve 13 is driven to make rotating motion around bearing inner race 7, impeller
The 14 stirring intracorporal liquid of large tank.
