具体实施方式Detailed ways
下面将结合附图和实施例对本实用新型做详细的介绍：The utility model will be described in detail below in conjunction with accompanying drawing and embodiment:
如图1所示，这种超声波雾化换能器，适用于雾化除尘、降温，食品加工领域等。在中高频(20kHz～70kHz)工作情况下，具有雾化量大、雾化作用范围广、输出功率大、不易结垢、高低温环境下性能稳定、应用领域范围较广等特点，并且成品率高、成本较低。主要包括换能器、雾化头5和超声驱动电源，换能器与超声驱动电源相连接，其中换能器包括前盖板7、后盖板2和PZT-8压电陶瓷3，导水管1从换能器的后盖板2进入直接通到前端的雾化头5并与之相连接，雾化头5呈倒圆台形结构并采用耐用较轻和韧性好的钛合金制成。换能器的前盖板7上设有节点法兰4，用于将换能器安装在流水线安装板6上；液体从导水管1进入，通过PZT-8压电陶瓷3的高频振荡，将液态水分子结构打散，通过雾化头5的底孔喷出，形成雾状。As shown in Figure 1, this ultrasonic atomization transducer is suitable for atomization dust removal, cooling, and food processing fields. Under the working condition of medium and high frequency (20kHz～70kHz), it has the characteristics of large amount of atomization, wide range of atomization, large output power, not easy to scale, stable performance in high and low temperature environment, wide application range, etc., and the yield rate is high. High and low cost. It mainly includes a transducer, an atomizing head 5 and an ultrasonic driving power supply. The transducer is connected to the ultrasonic driving power supply. The transducer includes a front cover 7, a rear cover 2, a PZT-8 piezoelectric ceramic 3, and an aqueduct 1. From the rear cover plate 2 of the transducer, it enters and connects with the atomizing head 5 directly leading to the front end. The atomizing head 5 has a rounded truncated structure and is made of durable, light and tough titanium alloy. The front cover plate 7 of the transducer is provided with a node flange 4, which is used to install the transducer on the assembly line mounting plate 6; the liquid enters from the aqueduct 1, passes through the high-frequency oscillation of the PZT-8 piezoelectric ceramic 3, The molecular structure of liquid water is broken up and sprayed out through the bottom hole of the atomizing head 5 to form a mist.
所述的雾化头5的底孔形状是多个菱形孔的组合结构，增大雾化头底孔的孔径，更好的达到增大雾化作用面积的效果。The shape of the bottom hole of the atomizing head 5 is a combined structure of multiple diamond-shaped holes, increasing the aperture of the bottom hole of the atomizing head to better achieve the effect of increasing the atomization area.
由于采用了导水管1从换能器的后盖板2进入直接通到前端的雾化头5并与之相连接的结构，因此导水管1可以做的比其他部位进水要大，本实用新型中按需加大了导水孔的孔径大小，以增加液体流量；再通过计算，设计和流量相适应的振子、前盖板及雾化头。在本实用新型设计中，相应的增加了换能器的输出功率和振子振幅，以保证对扩大了的导水管内液体能够完全进行处理，在保证雾化效果的同时，增加雾化量。Since the water guide pipe 1 enters from the rear cover plate 2 of the transducer and directly leads to the atomizing head 5 at the front end and is connected with it, the water guide pipe 1 can be made larger than other parts of the water inlet. In the new model, the diameter of the water guide hole is increased as needed to increase the liquid flow; and then through calculation, the vibrator, front cover and atomizing head are designed to match the flow. In the design of the utility model, the output power of the transducer and the amplitude of the vibrator are correspondingly increased to ensure that the liquid in the enlarged aqueduct can be completely processed, and the atomization amount is increased while ensuring the atomization effect.
工业应用中要根据实际情况来确定最佳雾化颗粒大小。本实用新型设计中，通过计算仿真，调整换能器的振幅大小，来改变产生的雾化颗粒大小。通过改变换能器频率、功率容量、导水管孔径和雾化头锥面来改变雾化的参数。In industrial applications, the optimal atomized particle size should be determined according to the actual situation. In the design of the utility model, the size of the generated atomized particles is changed by adjusting the amplitude of the transducer through calculation and simulation. The atomization parameters are changed by changing the frequency of the transducer, power capacity, aperture of the water guide pipe and the cone surface of the atomization head.
如图2所示，多个换能器安装在流水线安装板6上，并联后与超声驱动电源相连接，是一体式的整机安装整体系统，主要是组合整列使用。As shown in Figure 2, multiple transducers are installed on the assembly line mounting plate 6, and connected in parallel with the ultrasonic drive power supply.
