Description
Technical field
The invention belongs to the pharmaceutical equipment field, particularly relate to the blade that is applied in the mixer and change mechanism.
Background technology
Be applied to blade in the mixer and change mechanism and utilize mechanical force and gravity etc., the machinery that two or more material is evenly mixed.Being applied to blade in the mixer changes mechanism's tool and is widely used in pharmaceutical industry.Being applied to blade in the mixer changes mechanism and not only various materials can be fitted in uniform mixture; Can also increase the material contact surface area, to promote chemical reaction; Can also accelerate physical change, for example granular solute adds solvent, but changes the effect accelerate dissolution mixing of mechanism's tool by being applied to blade in the mixer.
Main body convection current diffusion and eddy diffusivity that stirring causes, the surface area that increases molecular diffusion between different liquids has reduced diffusion length, thereby shortens the time of molecular diffusion.If treat that the viscosity of mixed liquid is not high, can in not long mixing time, reach the state that mixes at random; If viscosity is higher, then need long incorporation time.
The blade in the mixer of being applied to of a small amount of undissolved powdery solid and liquid changes mechanism's reason, and is different from the density composition, and to change mechanism's reason identical for the blade in the mixer of being applied to of immiscible liquid, just stirs the granularity that can not change powdery solid.If solid particle can not make its sinking speed less than the flowing velocity of liquid before mixing, adopt which kind of agitating mode all to can not form uniform suspension.
The mixing of different pastes mainly is to treat that mixed material repeatedly cuts apart and make it strong shear action that action produces such as be pressed, roll over, squeeze, subsequently again through repeatedly merging, mediating, to reach at last desired mixability.This mixing is difficult to reach desirable and mixes, and only can reach at random and mix.Powdery solid be paste after a small amount of liquid mixes, it is applied to blade in the mixer, and to change mechanism's reason identical with the mechanism of plaster material mixing.
Different thermoplastic and thermoplastic are mixed with a small amount of powdery solid, need to rely on strong shear action, rub repeatedly and mediate, and just can reach at random and mix.
If the granular solids owner of good fluidity is by the revolution of container itself, or be mounted on the effect of moving component in the container, stir repeatedly, admix and mixed, this class material also available air-flow generation convection current or turbulent flow to reach mixing.The convection current of solid particle or turbulent flow are difficult for producing eddy current, and mixing velocity is far below the mixing of liquid, and mixability generally also can only reach at random mixes.
Mobile very poor, the particle or the powdery solid that adhere to occurs mutually, then often need with stir and press with machinery, the blade that is applied in the mixer of the action such as rolling changes mechanism's tool.
The existing blade that is applied in the mixer changes the common complex structure of mechanism in the market, and cost is higher, all is not suitable for using at small-size laboratory.Therefore, need a kind of blade that is applied in the mixer simple in structure, that manufacturing cost is lower of development to change mechanism.
Summary of the invention
Technical problem to be solved by this invention provides a kind of blade that is applied in the mixer and changes mechanism, and this is applied to blade in the mixer, and to change mechanism structure simple, and manufacturing cost is lower; Be highly suitable in the laboratory the even mixing to dryness or moist powder, and in mixed process, can not produce melting, the volatilization or rotten of material.
The present invention solves the problems of the technologies described above the technical scheme that adopts: the blade that is applied in the mixer changes mechanism, comprise mainframe, hopper, rotating shaft and the motor that drives the rotating shaft running, described hopper is made of two side and bottom surfaces in opposite directions; Two sides of hopper are provided with two circular holes in opposite directions; Described rotating shaft is connected with paddle shaft, locating shaft in turn, and rotating shaft is connected with by nut and is applied in its inner paddle shaft, and described paddle shaft runs through away from an end of rotating shaft and is arranged on locating shaft inside, and described paddle shaft is provided with blade; Rotating shaft and locating shaft are installed in respectively circular hole inside.
Based on foregoing, the present invention will be in order to be transformed into mixer for convenience detach with the mixer that mainframe, hopper, rotating shaft three parts consist of, the spy is connected with paddle shaft, locating shaft in turn on the basis of rotating shaft, the position of blade is moved on on the paddle shaft by rotating shaft, because the locating shaft among the present invention and the inside of rotating shaft all are the structures that adopt hollow, therefore paddle shaft can move in the inside of locating shaft and rotating shaft, and paddle shaft relies on nut and rotating shaft to be fixed together simultaneously.Utilize rotating shaft drive paddle shaft and blade to rotate together.When dismounting, be about to nut and unclamp, paddle shaft is moved towards locating shaft or rotating shaft direction, until an end of paddle shaft is revealed the position.Can take off blade this moment from paddle shaft, the blade that then more renews, and then reverse aforesaid operations is installed.Can realize easily dismounting and installation.
Described hopper top also arranges the groove lid that is complementary.
Described groove covers to be provided with and lifts ring.
The cross section of described hopper is U-shaped.
Described blade is spiral-shaped; And the quantity of described blade is 2.The below of described hopper is provided with casing.
In sum, the present invention compared with prior art has following advantage:
(1), the present invention arranges simple in structurely, manufacturing cost is lower, it is also comparatively convenient to operate.
(2), the present invention can automation mechanized operation, saves manpower.
(3), the present invention is not only applicable to pharmaceutical industry to the mixing of material, also be applicable to chemical industry, food, etc. the industrial department small lot mix different major-minor materials.
(4), the present invention is particularly suitable in the laboratory the even mixing to dryness or moist powder, and can not produces melting, the volatilization or rotten of material in mixed process.
