The stirring device in the utility model is on the basis of the current stirring device composed by a connecting device connected with the power source, a speed reduction device and stirring blades, the input shaft connected with the speed reduction device is coupled with the output shaft via a magnetic force transmission device, a connecting device is disposed between the output shaft and the stirring blades.
Description
Technical field
The utility model relates to a kind of device, particularly Installed System Memory that medium in the system is stirred of being used at inflammable, explosive, murder by poisoning or corrosive medium, the device that the system that requires sealing to avoid medium to leak stirs.
Background technology
At present; sealing of device conventional machinery or packing seal that Installed System Memory is stirred at inflammable, explosive, murder by poisoning or corrosive medium; the corollary equipment one flue gas desulfurization side-feeding mixer that for example shows domestic flue gas desulfurization device in thermal power plant; mechanical seal or the gland sealed axle envelope agitators that adopt import more; the structure of this agitator the sealing leak problem can occur inevitably; the axle envelope is often damaged; service life is short; disorderly closedown is frequent; not only environment is polluted, and strengthened the overhaul of the equipments replacement cost.
Summary of the invention
The utility model is a kind of agitating device that overcomes the prior art deficiency.Non-failure operation time is long, makes very big broadening of time between overhauls(TBO), is provided with the on-bne repair device especially.
Device of the present utility model is on the basis of the existing agitating device that is made of the coupling arrangement, deceleration device and the stirrer paddle that link with power source, the power shaft that links to each other with deceleration device is provided with coupling arrangement by a magnetic drive device and output shaft coupling between output shaft and stirrer paddle.
Magnetic drive device in the agitating device of the present utility model by: with the active magnetic rotor of power shaft rigid attachment, mate the driven magnet rotor that carries out transmission with the active magnetic rotor, be arranged at the separation sleeve of the magnetic conduction between active magnetic rotor and the driven magnet rotor, and the shell that is used to be provided with active magnetic rotor and driven magnet rotor.
As a kind of preferred structure of the present utility model, be that the active magnetic rotor is outer magnet rotor, driven magnet rotor is interior magnet rotor.
The technical solution of the utility model is based on Drive Technology, uses the magnetic force of permanent-magnet material or electromagnet generation, comes a kind of technology of realizable force or moment of torsion non contact transmission.Magnetic driver is made up of inside and outside magnet rotor and separation sleeve three parts, and inside and outside magnet rotor is isolated fully by separation sleeve, and promptly inside and outside magnet rotor does not contact.Owing to have magnetic field between the inside and outside magnet rotor, when magnet rotor rotates outside driving machine drives, outer magnet rotor can rotate thereby drive the work package that is connected with interior magnet rotor synchronously by the magnetic force coupling in interior magnet rotor, has realized the purpose of non contact transmission moment of torsion.The design feature of magnetic driver is: do not have axle envelope, static seal, inside and outside magnet rotor is isolated fully by separation sleeve, carries out floppy drive by magnetic force and moves.Sealing is compared with existing mechanical, can thoroughly solve to leak and machine envelope wear problem.
Agitating device of the present utility model can thoroughly solve the leakage problem of prior art, and can reduce wear, and prolongs the service life (20000 hours) of agitating device, and has advantages such as simple in structure, easy to maintenance.
Description of drawings
Accompanying drawing 1 is the overall structure schematic diagram of an embodiment of the utility model, and accompanying drawing 2 is the part rotation section enlarged diagram at A position among Fig. 1.Among the figure: 1 is drive motors, 2 is deceleration device, 3 for being provided with the shell of magnetic drive device, 4 for being arranged at the coupling arrangement between output shaft and paddle shaft, and 5 is stirrer paddle, and 6 is output shaft, 7 for being fixedly set in the interior magnet rotor on the axle 6,8 are 9 separation sleeve between magnet rotor 6 in being arranged at and outer magnet rotor, and 9 is outer magnet rotor, and 10 is the power shaft of outer magnet rotor.
The specific embodiment
Accompanying drawing provides an embodiment of the present utility model, below in conjunction with description of drawings.
Embodiment of the present utility model shown in Figure 1 is by as motor 1, the deceleration device 2 of agitating device power source and be arranged at magnetic drive device in the shell 3, be used to connect the coupling arrangement 4 of paddle rachis and magnetic drive device output shaft, and stirrer paddle 5 constitutes.In the present embodiment, the moment of torsion of exporting from deceleration device 2 is directly to transmit with axle, can certainly realize the transmission of moment of torsion as shaft coupling by another coupling arrangement of other setting.
The interior details of magnetic drive device that is positioned at shell 3 among Fig. 1 is referring to accompanying drawing 2.As seen from Figure 2, pass on the outer magnet rotor 9 that fixedly installs thereon through power shaft 10, and the magnet rotor 7 that is positioned at outer magnet rotor 9 is fixedly set on the output shaft 6 through installing 2 moments of torsion after slowing down.Magnet rotor in the present embodiment all adopts the permanent-magnet material manufacturing, also can adopt electromagnet to make magnet rotor according to different requirements certainly.But between inside and outside magnet rotor 7 and 9, be provided with the separation sleeve of manufacturing by permeability magnetic material 8, as can be seen from Fig. 2, separation sleeve free end, an end that just keeps left among Fig. 2 is on the flange that is fixed in the system of being stirred, therefore, be communicated with in the separation sleeve with in being stirred system, the separation sleeve outside then complete be stirred system and insulate mutually.Because inside and outside magnet rotor 7 is isolated by separation sleeve 8 fully with 9, so do not contact fully between inside and outside magnet rotor.But owing to have magnetic field between the inside and outside magnet rotor, when magnet rotor 9 rotates outside drive motors 1 drives, the coupling that outer magnet rotor 9 can pass through magnetic force is carried out the rotation of basic synchronization in interior magnet rotor 7 thereby drive the blade 5 that is connected with interior magnet rotor 7, has realized the non contact transmission moment of torsion.And between inside and outside magnet rotor, do not have any relative friction campaign, therefore there are not disadvantages such as ubiquitous wearing and tearing, seal break-off in the prior art fully.Can reach more than 20000 hours its service life.
