Abstract
The utility model discloses a magnetic transmission stirring device for a laboratory glass reaction bulb, mainly composed of an inner magnetic rotor, an outer magnetic rotor, a separation sleeve, a bearing seat, a stirring axle, a stirring blade, a corresponding bearing and a corresponding sealing element. The utility model has the advantages of good sealing effect, without dynamic seal leakage problem. The utility model is especially suitable for being used under the vacuum conditions, with compact device structure, convenient mounting, dismounting and replacing of components, stable and reliable operation and long service life.
Description
Technical field: the utility model relates to a kind of transmission agitating device of glass reaction bottle usefulness, the magnetic drives agitating device that particularly a kind of vacuum state lower-glass reaction bulb is used.
Background technology: be used for the stirring transmission device of glass reaction bottle in the existing laboratory, mainly by electric mixer, shaft and on paddle, formations such as rubber stopper and seal.This stirring relies on the movable sealing between seal and the shaft to realize sealing, in use have the following disadvantages: have inevitable sealing leak, can't adapt to some seal requests very high agitation reaction (as the stirring under the vacuum state), and along with the wearing and tearing service life and the reliability of seal also is affected.
Summary of the invention: the purpose of this utility model is at deficiency of the prior art, and proposes a kind of magnetic drives agitating device of glass reaction bottle usefulness, and its seal form is a static seal, can solve the leakage problem that movable sealing exists fully.Other purpose of the present utility model is: mate fully with existing glass reaction bottle specification, it is very easy to substitute former agitator, the apparatus structure compactness, and it is convenient that parts are changed in mounting or dismounting, and running is steadily reliable, long service life.
Can realize the purpose of this utility model by following technical proposals: a kind of magnetic drives agitating device of glass reaction bottle usefulness, comprise electric mixer, shaft and on paddle, it is characterized in that shaft top is provided with magnet rotor in the tubular, shaft is fixed in the bearing block with axle sleeve, separation sleeve with magnet rotor cover in shaft top and the tubular within it, its bottom is connected with the bearing block static seal by clamp nut, bearing block cooperates with the bottleneck static seal of reaction bulb, be provided with an outer magnet rotor that is rotatably assorted synchronously with interior magnet rotor in the separation sleeve outside, outer magnet rotor is connected with electric mixer by plastic flexible pipe.
Magnet rotor is to be made of the iron rotor ring that outer wall is provided with watt type permanent magnet of lining up circumference in the tubular, and its outside is provided with a corrosion protective covering.Outer magnet rotor is provided with the iron outer rotor of watt type permanent magnet of lining up circumference and outer bearing and bearing cap by its inwall and forms, outer bearing sleeve is at the separation sleeve lateral wall, supported by step on it, iron outer rotor top is provided with one section little axle and is connected by plastic flexible pipe with the output shaft of electric mixer.
Shaft is slidingly matched by two two carbon graphite axle sleeves and bearing blocks that are located at bearing block inner chamber upper and lower side.Bearing block is provided with the positioning boss that cooperates with separation sleeve, and the mating surface of separation sleeve and bearing block is provided with an O RunddichtringO at least.
Its axial cross section of bottleneck mating surface of bearing block and glass reaction bottle is a back taper, is provided with an O RunddichtringO on mating surface at least.
According to different service conditions, separation sleeve is made by engineering plastics or stainless steel.
Effect of the present utility model is: 1, good sealing effect, this mainly is to adopt magnetic force static seal drive technology can stop fully to leak, and the pressure of system (or vacuum) relies on the static seal between separation sleeve and bearing block and bearing block and the vial to guarantee.Therefore this device very is suitable for the various stirring reactions high to seal request in the laboratory.2, the interface specification of bearing block is consistent with existing glass bottle opening specification, need not other change, can on existing glass reaction bottle, dispose this utility model.3, apparatus structure compactness, easy accessibility can be changed various paddle easily to adapt to different stirring demands.4, operate steadily, contactless wearing and tearing, physical life is long.This is that mainly self-lubricating effect is good between shaft and the carbon graphite axle sleeve, and the resistance to chemical attack of carbon graphite own.5, separation sleeve can adopt engineering plastics to make, and has avoided the generation of magnetic eddy current, is suitable for the high-speed stirred environment.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment: referring to accompanying drawing, shaft 1 epimere is contained in the bearing block 2, is slidingly matched fixing by two carbon graphite axle sleeves 5 that are located at bearing block 2 inner chamber upper and lower sides between them.Magnet rotor 6 is enclosed within shaft 1 upper end in the tubular, transmits moment of torsion by sector, and magnet rotor 6 is made of the iron rotor ring and the corrosion protective covering that are pasted with watt type permanent magnet that is arranged in circumference on it in the tubular.Anticorrosive coat can be that plastics or stainless steel are made.Separation sleeve 8 is connected and fixed by clamp nut 9 with bearing block 2, and both connect the place, plane and are provided with an O RunddichtringO 10 at least, relies on the pretightning force of clamp nut 9 to realize static seal.Be with outer magnet rotor 7 outside the separation sleeve 8, outer magnet rotor 7 is pasted with iron outer rotor, outer bearing 4 and bearing cap 3 formations of watt type permanent magnet that is arranged in circumference by its inwall.Iron outer rotor top is provided with one section little axle and is connected by plastic flexible pipe with the output shaft of electric mixer.Outer bearing 4 is installed on separation sleeve 8 lateral walls, is axially supported by the step that is located on the sidewall.Axial restraint is tightened by threaded bearing cap 3 in outer bearing 4 outer rings.The latter half of bearing block 2 is and the corresponding to inverted cone-shaped structure of glass reaction bottle bottleneck specification, is provided with an O RunddichtringO 11 at least on both mating surface.Bearing block 2 lower port inner cavity surface are provided with screw thread, a cock cap 12 be threaded, can prevent down that graphite bushing 5 skids off vertically.Separation sleeve 8 is made by engineering plastics or stainless steel, and inside and outside watt of type permanent magnet can be ferrite, neodymium iron boron or rare earth magnetic steel.Outer bearing 4 can use deep groove ball bearing, needle bearing or sliding bearing.
The workflow of this device is: electric mixer drives the outer magnet rotor 7 of cartridge type and rotates, and drives magnet rotor 6 rotations in the cartridge type by the transmission of magnetic force moment of torsion, and makes its rotation for the paddle 14 that is connected on it transmission of power by shaft 1 with shaft coupling 13.
