Abstract
The utility model relates to a stirring device which is especially applicable to acidity environment as well as the easily corrosive and abrasive acidity environment of an organic medium solution. The stirring device structurally comprises a stirring shaft, a stirring paddle fixing plate, a fixed flange, a blade type stirring paddle, an upper protective cover and a lower protective cover, wherein the stirring paddle fixing plate penetrates through the stirring shaft and is clamped on a boss at the lower bottom end of the stirring shaft, the fixed flange is pressed on the stirring paddle fixing plate, the upper edge of the blade type stirring paddle is fixed at the lower bottom of the stirring paddle fixing plate, the upper protective cover is buckled and pressed on the top surface of the stirring paddle fixing plate, and the lower protective cover is buckled and pressed on the bottom surface of the stirring paddle fixing plate. In the stirring device provided by the utility model, the metal stirring shaft, metal fixed bolts and nuts can be separated from a medium solution, and metal impurities are prevented from entering a stirring medium so that the extraction quality is guaranteed; and the corrosion resistance of a stirring paddle in the medium is effectively increased, and the service life of the stirring paddle is long. The stirring device is easy in combination and convenient to assemble and disassemble.
Description
Technical field
A kind of agitating device relates to the agitating device that uses under a kind of perishable, abrasion environment of perishable, wearing and tearing acidity and the organic media solution that is specially adapted to acidity and organic media solution.
Background technology
In metallurgy, chemical engineering industry, the equipment that uses often is to use under perishable, the abrasion environment of acidity and organic media solution, operating equipment very easily produces perishable, the damage of acidity and organic media solution, and the corrosion resistance of the agitating device of use is extremely important.In chemical process, its whipping process ordinary circumstance is above reaction vessel, and agitating device is set.Its agitating device is generally the corrosion resistant metal mold, such as titanium, and steel lining plastic and plastics etc., all there is certain defective in its agitating mode.Titanium has good corrosion resistant performance, but the titanium material is light, is subjected to the impact of buoyancy at running, easily causes shaft to fracture; Although steel lining plastic can be avoided the problem of fractureing, the anti-rot plastic layer of steel lining plastic easily is scratched, and acid medium infiltrates its corrosion of steel, causes iron tramp to enter solution influenced product quality; Although plastics have overcome above-mentioned deficiency, not only wear-resisting but also corrosion resistant, shaft and paddle weld easily come off, and cause the general liquid of mixer-settler extractor.
Summary of the invention
The purpose of this utility model is exactly the deficiency that exists for above-mentioned technology, provides that a kind of cost of manufacture is low, corrosion resistant and anti-wear performance is good, long service life, agitating device that mixing effect is good.
The purpose of this utility model is achieved through the following technical solutions.
A kind of agitating device is characterized in that its structure comprises:
Shaft, this shaft are the vertical rotation axle that is covered with the plastics jacket layer on the axial wall, and the bottom is provided with boss structure under the axle;
Paddle fixed head, this paddle fixed head are one to have between two parties the circular flat board of through hole; This paddle fixed head through hole from having is passed shaft, is installed on the boss of bottom under the shaft;
Mounting flange, this mounting flange are to be fitted in plane face flange on the stirring arm fixed head and that be fixedly connected by bolt, nut with the stirring arm fixed head, described mounting flange and stirring arm fixed head and shaft key connecting;
Paddle, this stirring arm is fixed on the vane type paddle of paddle fixed head on going to the bottom for circumferential uniform, upper edge;
Upper protective cover, this protective cover are one to be provided with between two parties that to pass shaft through hole, lower end be that box-like cover body on the paddle fixed head, that mounting flange is buckled in the inside is withheld on uncovered, lower edge;
Lower protective cover, this protective cover be the coaxial setting of a shaft, upper end be uncovered, upper edge withhold below the paddle fixed head, with shaft lower end, set bolt and nut be buckled in the inside box-like cover body.
A kind of agitating device of the present utility model; the metal shaft is provided with the plastic protective sleeve layer; the upper and lower protective cover that is provided with plays metal flange metal, shaft lower end and metal set bolt, nut cover; itself and medium solution are separated; avoided metal impurities to enter agitated medium, the extraction quality is protected.The part that paddle contacts with corrosive medium-metal shaft, metal flange and bolt adopt respectively plastic bushing and plastic protective plate to weld parcel, have improved the corrosion resistance of stirring arm in medium, long service life.The metal shaft adopts bolted to be connected with stirring cover plate, can solve well the radial location of shaft, makes its difficult drop-off that is in operation, and is easy to combination, and is easy to loading and unloading.
Description of drawings
Fig. 1 is the structural representation of utility model.
The specific embodiment
A kind of agitating device is characterized in that its structure comprises:
Paddle fixed head 3, this paddle fixed head are one to have between two parties the circular flat board of through hole; This paddle fixed head through hole from having is passed shaft, is installed on the boss of bottom under the shaft;
Mounting flange 4, this mounting flange are to be fitted in plane face flange on the stirring arm fixed head and that be fixedly connected by bolt, nut 5 with the stirring arm fixed head, described mounting flange and stirring arm fixed head and shaft key connecting;
Upper protective cover 7, this protective cover are one to be provided with between two parties that to pass shaft through hole, lower end be that box-like cover body on the paddle fixed head, that mounting flange is buckled in the inside is withheld on uncovered, lower edge;
Lower protective cover 8, this protective cover be the coaxial setting of a shaft, upper end be uncovered, upper edge withhold below the paddle fixed head, with shaft lower end, set bolt and nut be buckled in the inside box-like cover body.
During making; metal shaft outside cover is lined with plastic bushing; the plastics stirring vane is welded on paddle fixed head lower surface; metal shaft lower end key connection metal ring flange; the paddle fixed head is fixedly connected on metal flange through bolt, and protective cover on the plastics is installed in paddle fixed head upper surface, protective cover under the plastics is installed in the lower surface.The protective cover material can be the polyvinyl chloride backplate, and bolt head and the clamp nut that will expose respectively seal, thus make shaft and stirring arm junction fully and medium solution separate, greatly improved the corrosion resistance of agitating device.
