Abstract
The utility model discloses an upper magnetic stirring apparatus which comprises a drive mechanism, a stirring shaft as well as stirring blades and also comprises an internal magnetic shaft, an external magnetic shaft and an isolating sleeve, wherein, the stirring blades are arranged on the stirring shaft; the isolating sleeve is welded with the top part of a pot into a whole; the internal magnetic shaft is arranged in the isolating sleeve; the external magnetic shaft is arranged outside the isolating sleeve; a permanent magnet is arranged on the internal magnetic shaft; a permanent magnet is arranged at one end of the external magnetic shaft, which is corresponding to the internal magnetic shaft; a center locating shaft is arranged at the lower part of the isolating sleeve; the external magnetic shaft is arranged and positioned on the center locating shaft of the isolating sleeve through a bearing; the external magnetic shaft is fixedly connected with the stirring shaft the length of which reaches to the bottom of the seal pot. With the upper magnetic stirring apparatus, the mechanical transmission in the prior art is changed into the magnetic transmission torque, the isolating sleeve is integrated with the top of the pot, no mechanical sealing is needed, and no leakage exists, thereby satisfying the stirring demand of the sanitary medicine.
Description
Technical field
The utility model relates to a kind of agitating device, particularly a kind of pharmaceutical sanitary field that is applied in, the last magnetic stirring apparatus that stirs by the magnetic force transmission.
Background technology
Traditional mechanical agitator is to adopt machine driving to transmit moment of torsion, drives shaft and stirrer paddle.Frame is installed on the stirred vessel, motor reducer is fixed on the frame of stirred vessel, rigid bearing is arranged in the middle of the frame, shaft is divided into major axis and minor axis, minor axis one end of shaft links to each other with the output shaft of motor reducer, the other end extend into stirred vessel inside, links to each other with major axis by shaft coupling, between shaft and the stirred vessel mechanical seal is installed.For higher stirred vessel, need bearing or pull bar be installed in the stirred vessel bottom, to prevent the swing of shaft.Because the mechanical seal of installing between shaft and the stirred vessel belongs to movable sealing, there is the hidden danger of leakage, mechanical seal simultaneously belongs to easily-consumed products, and often maintenance and maintenance do not meet the requirement that allows leakage anything but of special industry.
The utility model content
The problem of the easy leakage that exists at prior art, the purpose of this utility model is to provide a kind of mechanical seal of saving, and avoids the last magnetic stirring apparatus that leaks fully.
The technical scheme in the invention for solving the technical problem is: a kind of magnetic stirring apparatus of going up, comprise transmission device, shaft and stirrer paddle, stirrer paddle is installed on the shaft, also be provided with interior magnetic axis, outer magnetic axis, separation sleeve, described separation sleeve and tank top are integrally welded, magnetic axis is positioned at separation sleeve inside in described, described outer magnetic axis is positioned at the separation sleeve outside, on the magnetic axis alnico magnets are housed in described, the end that described outer magnetic axis is relative with described interior magnetic axis is equipped with alnico magnets, described separation sleeve bottom is a centralized positioning axle, described outer magnetic axis is installed by bearing and is positioned on the described separation sleeve centralized positioning axle, described outer magnetic axis is fixedlyed connected with described shaft, and described shaft length is to the hermetically sealed can bottom.
The described magnetic stirring apparatus of going up, described outer magnetic axis is installed on the centralized positioning axle of described separation sleeve by two wear-resisting ceramic bearings, and fixes by hanging bolt.
Described magnetic stirring apparatus, described interior magnetic axis upper end is equipped with the up-down adjustment device, and described up-down adjustment device comprises set screw, handwheel.
Described magnetic stirring apparatus, described outer magnetic axis is an Open architecture.
Described magnetic stirring apparatus, the permanent magnet outsourcing on the described outer magnetic axis is with 316L type stainless steel sleeve.
The utility model transmits moment of torsion by mechanical transfer of the prior art being changed into magnetic force, fuse by separation sleeve and tank deck, do not need mechanical seal, and exhausted nothing is leaked, and the up-down adjustment device that is provided with can be for convenience detach, debugging, dismounting and packing, and the open by design of outer magnetic axis, the water that coagulates of cleaning and sterilization can flow out along the centralized positioning shaft end of separation sleeve, satisfies the needs that clean and sterilize.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of magnetic stirring apparatus of going up, comprise transmission device 27, shaft 2 and stirrer paddle, 1 stirrer paddle 1 is installed on the shaft 2, magnetic axis 10, outer magnetic axis 6, separation sleeve 11 in also being provided with, separation sleeve 11 is integral with the hermetically sealed can welded top, interior magnetic axis 10 is positioned at separation sleeve 11 inside, outer magnetic axis 6 is positioned at separation sleeve 11 outsides, on the interior magnetic axis 10 alnico magnets 9 are housed, the end that outer magnetic axis 6 is relative with interior magnetic axis is equipped with alnico magnets 8, and 8 outsourcings of the permanent magnet on the magnetic axis outside are with 316L type stainless steel sleeve.
For the ease of dismounting and maintenance, in interior magnetic axis 10 upper ends the up-down adjustment device is installed, described up-down adjustment device comprises set screw 24 and handwheel 23.In the time of dismounting, interior magnetic axis 10 is raised pull out outside the magnetic field so easily dismounting earlier.
Outer magnetic axis 6 is an Open architecture, and the water with fixed attention in the time of can making CIP that whom clean with the SIP sterilization flows out along the centralized positioning shaft end of separation sleeve, and no dead angle can be carried out SIP sterilization and CIP cleaning on the spot, satisfies the requirement of CMP to equipment.
More than be preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model when the function that is produced does not exceed the scope of technical solutions of the utility model, all belong to protection domain of the present utility model.
