Abstract

The utility model relates to an ultrasonic heating device. The device comprises a control cavity and a heating bar. The control cavity is provided with a wiring port, a control switch, a handle and the like. When the control switch is connected, high-frequency currents generated by an ultrasonic power source are input into a piezoelectric patch located in the heating bar through a first high-frequency wire and a second high-frequency wire, the piezoelectric patch generates high-frequency vibration under the effects of the high-frequency currents, the high-frequency vibration is transmitted to a matching layer, the matching layer transmits the high-frequency vibration to fluid around the heating bar in the mode of ultrasonic waves, and accordingly the fluid is stirred and heated. The ultrasonic heating device can heat high-viscosity, low-heat-conductivity and inflammable fluid, sound energy of the ultrasonic heating is dissipated more quickly in the high-viscosity fluid and the heating effect is better; due to the existence of sound streams, mixing and stirring are accelerated, and the low-heat-conductivity fluid can be heated quickly; meanwhile, due to the fact that the sound energy has good energy transmission performance, the phenomenon that the local temperature of the fluid is too high is unlikely to occur, and therefore the inflammable fluid can be heated safely.

The specific embodiment

Below by drawings and Examples, the technical solution of the utility model is described in further detail.

Ultrasonic Heating device of the present utility model not only can heat common fluid, can also be sticky to height, lower thermal conductivity and inflammable fluid heat.

Fig. 1 is the structure principle chart of the Ultrasonic Heating device of a kind of embodiment of the present utility model, Fig. 2 is the structural representation of the Ultrasonic Heating device of a kind of embodiment of the present utility model, shown in Fig. 1 and Fig. 2, Ultrasonic Heating device mainly comprises control chamber 11, gauge tap, heating rod 31.

Control chamber 11, is provided with connection jaws 12, the first high frequency wires 41 and passes in control chamber 11 by connection jaws 12.Gauge tap is used for connecting the first high frequency wire 41 and the second high frequency wire 42, and gauge tap comprises total control switch 13 and hierarchical control switch 14, be arranged on control chamber 11, hierarchical control switch 14 the scope of application that has expanded Ultrasonic Heating device is set.In heating rod 31, be equipped with the second high frequency wire 42, the surface of heating rod 31 is provided with protruding matching layer 32, and matching layer 32 has notch in the chamber of heating rod 31, is equipped with piezoelectric patches 43 in notch, be connected with the second high frequency wire 42, piezoelectric patches 43 sticks on the notch of matching layer 32.

In the time that total control switch 13 is closed, the high frequency electric that ultrasonic-frequency power supply produces is inputted in piezoelectric patches 43 by the first high frequency wire 41 and the second high frequency wire 42, piezoelectric patches 43 produces dither under the effect of high frequency electric, and pass to matching layer 32, matching layer 32 transmits with hyperacoustic form dither in heating rod 31 fluid around again, thereby stirs and add hot fluid.Particularly, the macroscopic view that can produce fluid in ultrasonic vibration communication process flows, i.e. acoustic streaming, and acoustic streaming can be pushed near fluid matching layer 32 at a distance to, thereby realizes fluid agitation and heat transportation.Because matching layer 32 has acoustic impedance matching effect, can make the acoustic energy transmitance of transmitting in heating rod 31 fluid around improve more than 20%, reduce the energy loss causing due to acoustic impedance difference because of between piezoelectric patches 43 and heated fluid, matching layer 32 needs according to the acoustic impedance characteristic special design of heated fluid.In addition, matching layer 32 has the effect being in contact with one another between isolation piezoelectric patches 43 and heated fluid, meets safety in production and explosion-proof code requirement.

Further, control chamber 11 is connected with heating rod 31 by flange 21.On control chamber 11, be provided with handle 15, facilitate the hand-held mobile operation that waits.There is support column 33 at the top of heating rod 31, for preventing the wearing and tearing of heating rod 31 ends.Ultrasonic Heating device of the present utility model can also comprise preventing idle load device, can auto-breaking in the time that heating rod 31 exposes fluid, prevent piezoelectric patches 43 zero loads.

Particularly, the operating frequency of piezoelectric patches is 0.8MHz-4MHz.

The Ultrasonic Heating device course of work of the present utility model is as follows:

The handle 15 of hand-held ultrasound heater, is submerged into heating rod 31 in fluid to be heated; Start high frequency electric source, and closed total control switch 13, in the time of needs hierarchical control, the hierarchical control switch that now closed pair is answered; Now the first high frequency wire 41 is inputted piezoelectric patches 43 by the high frequency electric of high frequency electric source output by the second high frequency wire 42, piezoelectric patches 43 produces high frequency ultrasound and vibrates and pass to matching layer 32 under the effect of high frequency electric, matching layer 32 transmits ultrasonic vibration in heating rod 31 fluid around again, thereby stirs and add hot fluid; After to be heated completing, first powered-down, then heating rod is taken out, in order to avoid piezoelectric patches 43 zero loads are burned.

Ultrasonic Heating device of the present utility model, not only can heat common fluid, but also can be sticky to height, lower thermal conductivity and inflammable fluid heat.In the time that highly viscous fluid is heated, because acoustic energy dissipates sooner in highly viscous fluid, heating effect is better; In the time that the fluid of lower thermal conductivity is heated, because mix and blend has been accelerated in the existence of acoustic streaming, therefore Ultrasonic Heating device can heat the fluid of lower thermal conductivity faster; When flammable fluid is heated, because acoustic energy has good Energy transfer performance, fluid is difficult for producing the too high phenomenon of local temperature, heating flammable fluid that therefore can be safer.
