Description
Technical field
The present invention relates to a kind of calcium-removing reactor, particularly relate to and a kind ofly adopt that magnetic force drives, the calcium-removing reactor of hermetically sealed, mechanical stirrer.
Background technology
Along with science and technology development, China needs highly purified nuclear grade sodium increasing in research and production, and produce this highly purified sodium is as raw material with industrial sodium, after adding respective substance therein, through a series of operation, reaction and operation, one of them very important link is exactly the calcium impurities of removing wherein, the calcium-removing reactor of tradition use at present adopts the method for water-cooled, the shortcoming of this method maximum is to be absolutely unsafe, as everyone knows, sodium Metal 99.5 is met water and can sharply be reacted and blast, and the mode of water-cooled deliming has the leakage of water unavoidably, just in case this thing happens, consequence is with hardly imaginable; What the present in addition water-cooled deliming of using was adopted on equipment is dynamic seal, and this sealing method is needing examination and maintenance constantly in the work for a long time, and the probability that this sealing method generation is leaked is relatively large.As for considering that from energy-conservation and angle environmental protection the water-cooled deliming just more should not adopt.
Based on defective and the problem that water-cooled deliming method exists, people wish to abandon water-cooling pattern and adopt a kind of safer wind cooling method, rely on magnetic force driving, reliable sealing calcium-removing reactor.
Summary of the invention
The present invention be the shortcoming that exists of the water-cooled calcium-removing reactor that adopts in order to solve the highly purified nuclear grade sodium of present production with not enough, and provide a kind of calcium-removing reactor air-cooled, magnetic force driving that adopts.
The technical scheme that adopts:
Calcium-removing reactor comprises driving mechanism, covering heat shading apparatus, air cooling equipment, reactor shell and is installed in the intravital blade-carrying stir shaft of reactor cylinder that its structural feature is:
Described driving mechanism, comprise motor, speed reduction unit, external magnetic region, inner magnetic region, the input shaft of motor output shaft connection reducer, reducer output shaft is fixedlyed connected with the upper end of external magnetic region, external magnetic region is provided with centre hole, inner magnetic region is positioned at the external magnetic region centre hole, fixedlys connected with stir shaft in the lower end of inner magnetic region, and inner magnetic region and external magnetic region are installed in the magnetic drive shell body.
Described covering heat shading apparatus comprises heat shielding case, a plurality of heat shielding umbrella, and a plurality of heat shielding umbrellas are installed in the heat shielding case, fixedlys connected with stir shaft respectively in the center of a plurality of heat shielding umbrellas.
Described air cooling equipment, comprise reactor shell, air-cooled chuck, air-cooled inlet, air-cooled outlet, air-cooled chuck is installed in the outside of reactor shell, between upper and lower two end sockets, air-cooled inlet is installed in the bottom of a side of air-cooled chuck, is provided with air-cooled outlet at the middle part of relative opposite side.
Above-mentioned magnetic drive shell body upper flange is connected with upper bracket lower flange bolt, and magnetic drive shell body lower flange is connected with the lower bracket upper flange.
The following end flanges of above-mentioned heat shielding case is connected with the flange bolt at reactor shell upper cover top, and the upper flanges of heat shielding case is connected with bolt with the following end flanges of lower bracket.
Above-mentioned a plurality of heat shielding umbrellas are to make circle, umbrella with stainless steel plate.
Above-mentioned heat shielding umbrella is to make with the thick stainless steel plate of 0.6mm.
Principle of work
Motor rotates through variator external magnetic region is rotated, thereby has formed rotatingfield, makes inner magnetic region follow rotation, and the stir shaft that is connected with inner magnetic region drives blade and rotates.
Industry sodium enters raw material relevant in the reactor from the sodium inlet tube and adds from reinforced organ pipe, postheating, stirring, reaction, and the calcium slag of removing is discharged from the bottom scum pipe of reactor.Highly purified nuclear grade sodium takes out from the sodium outlet pipe, because of the reaction needed heating, naturally some heat has been used on the chemical reaction, yet also have some unnecessary heats along upwards conduction of stir shaft, be transmitted to inside and outside magnetic drives always, inside and outside magnetic drives and can lose magnetism gradually in the environment long-time, that temperature is too high, and the forfeiture serviceability.Installed heat shielding umbrella additional, along running into a plurality of heat shielding umbrellas in the process of stir shaft conduction, heat shielding umbrella plays the effect of heat radiation at heat for this reason, remains under the normal temperature conditions thereby make inside and outside magnetic drive envrionment temperature on every side.
The present invention adopts magnetic force driving, is active in one's movements, reliably, do not have the machinery wearing and tearing, do not have noise, sealing is reliable, the safety coefficient height of whole reactor work, the potential safety hazard that adopts air-cooled technology to produce so as not to sodium that leaks and water reaction, while is save energy again, has played environmental-protection function again.Utilized the mode of heat shielding umbrella to shield the conduction of heat effectively worn-out.Inside and outside magnetic is driven always work in the normal temps, prolonged the work-ing life that magnetic drives.Of the present invention being skillfully constructed, simple in structure, maintenance is few, and operation cost is low, the reactor that the suitable band that is applied in petroleum chemical industry stirs.Need to prove that under the prerequisite that does not change present principles, can also make some changes or distortion to the present invention, this belongs to protection scope of the present invention equally.
