Description
Technical Field
The utility model relates to the technical field of ultrasound, in particular to an ultrasonic injection syringe structure with a circulating heat preservation function for dispersing and uniformly mixing.
Background
Ultrasonic dispersion or mixing is to use ultrasonic vibration generated by a transducer to generate instant high-pressure vacuoles generated by cavitation effect in water (or liquid) to impact solid suspended particles in the water (or liquid), so that the solid particles can be uniformly suspended in the water (or liquid) without precipitation or agglomeration.
At present, the spraying liquid used in the spraying industry, especially the ultrasonic spraying industry, contains fixed particles with nanometer diameters, such as Pt/C particles contained in a fuel cell, and the fixed particles usually have cohesiveness and high density and are easy to precipitate at the bottom, when liquid is supplied through a needle cylinder, the solution is easy to be inhomogeneous in the conveying process, the concentration of the solid particles is uneven, so that the difference of the solid particles on the coating surface after spraying is large, and if the solid particles precipitate at the bottom, effective coating cannot be realized. Meanwhile, some spraying liquids have certain requirements on temperature, and the liquids can generate certain modification when the temperature is higher, so that the effects after coating are not good; for some more viscous liquids, the increased temperature increases the fluidity of the liquid, which facilitates the flow of the liquid through the pipe, and additional heating is required to increase the fluidity.
In order to solve the problem of liquid mixing, an ultrasonic injection needle cylinder with an ultrasonic mixing function is adopted in the prior art, but after ultrasonic vibration works for a period of time, a transducer generates heat and transfers the heat to liquid, meanwhile, vibration waves form a cavitation effect in the liquid, and the liquid can generate heat under the stirring action of the vibration waves, so that the temperature of the liquid is increased, and thus, the liquid modified due to the temperature increase is adversely affected;
the ultrasonic injection syringe with the ultrasonic mixing function in the prior art does not have a heat preservation function, and for some viscous liquid which needs to be heated to improve fluidity, the viscous liquid is heated in a water bath and then is sucked into the injection syringe, so that the operation is complex, and the longer the liquid supply process with low micro flow rate is, the more the temperature is reduced, and the greater limitation is realized.
Based on the above problems, how to provide a blending mode can maintain the ultrasonic dispersion or blending effect and also have good heating and cooling effects to maintain the temperature state of the sprayed liquid in the process of conveying the liquid, thereby not only realizing the uniform suspension of fixed particles in water (or liquid), but also maintaining the physicochemical characteristics of the fixed particles at the required temperature.
