Description
Technical field
The present invention relates to a kind of multifunctional mixer, is a kind of ultrasonic wave temperature control reinforcement mixer.
Background technology
Reinforcement mixer is that plurality of raw materials is uniformly mixed by one, makes it the equipment becoming a kind of mixture or have suitable viscosity.Some have the material of particular/special requirement, to dispersion precision and uniformity requirement very high, reinforcement mixer is only used to be difficult to meet the demands, as high speed nano lubricating fat and the preparation of other nanometer materials, the current comparative maturity of ultrasonic dispersion technique, the particle diameter of dispersion reaches below 1um, is far smaller than the smallest particles diameter of reinforcement mixer dispersion, have excellent dispersive property, ultrasonic dispersion technique is by means of " cavitation effect " Basic Mechanism.By supersonic generator by the signal of telecommunication higher than 20KHz frequency, after carrying out electrical power amplification, high-frequency mechanical vibration is changed into through hyperacoustic inversion electrical effect, energy is by the acoustic emanation of medium, the molecular oscillation in medium is made to produce countless tiny bubbles, these bubbles are cavitation bubble, cavitation bubble is formed along transonic direction at negative pressuren zone, growth, and thousands of atmospheric instantaneous pressures are produced at zone of positive pressure rapid closing, and the countless microcosmic high-pressure shocking wave of closed formation, cause physics, chemical change, this phenomenon is called as " cavitation effect ".During cavitation bubble collapse, the high temperature of more than 5000K is produced in the little space of extremely short time around its bubble, the high pressure of 5 × 107Pa, the rate of change of temperature up to 109K/s, and supervenes strong shock wave (producing high gas density) and the speed per hour jet up to 400Km/s.The high temperature formed in bubble, High Voltage, high gas density serve good stirring action, thus make two kinds of inconsistent liquid generation emulsifications, add the dispersing and dissolving of fast solute.Existing reinforcement mixer equipment does not possess ultrasonic disperse function, narrow application range, is difficult to the dispersion requirement meeting high accuracy nanometer materials.
Stir in production in reality, in order to by even for material stirring of different nature, require that agitating device possesses the function of emulsification, dispersion, homogeneous, mixing and pulverizing simultaneously, may need to use the stirring-head of number of different types to stir, to improve stirring efficiency simultaneously, strengthen mixing effect, particle in logistics is disperseed further, and traditional reinforcement mixer only has a stirring-head, inefficiency, change loaded down with trivial details, be difficult to realize above-mentioned functions.
The mixing dispersion of partial material needs to carry out at a certain temperature because of the requirement of its physicochemical properties, requires that mixing plant accurately controls stirring processing temperature, and traditional reinforcement mixer seldom possesses temperature control system because of the restriction of structure.
When stirring production, need the volume being uniformly mixed material may adjust change to some extent, require that rabbling mechanism possesses elevating function to adjust the relative altitude of stirring-head in barrel, traditional reinforcement mixer structure is simple, large multiplex manual adjustments mode is carried out, complex operation, positioning precision is poor, is difficult to realize automatic lifting and controls.
