Middle-feeding ultrasonic powerful resonance pulsed jet spray head device

Abstract

The invention relates to a middle-feeding ultrasonic powerful resonance pulsed jet spray head device. The device comprises an ultrasonic energy converter and a spray head fixedly connected with the ultrasonic energy converter, wherein the ultrasonic energy converter comprises an energy converter chamber formed by an energy converter shell and an energy converter upper cover; a longitudinally through high pressure water inlet pipe is fixedly arranged in the energy converter chamber; a longitudinal high pressure water channel is formed in the high pressure water inlet pipe; a piezoelectric ceramic sheet is fixedly arranged outside the high pressure water inlet pipe; the spray head comprises a spray head shell; an oscillation cavity is formed in the spray head shell and is communicated with the high pressure water channel; the upper end of the spray head shell is fixedly connected with the lower end of the high pressure water inlet pipe; the lower end of the spray head shell is provided with a nozzle; an amplitude-variable rod is arranged in the oscillation cavity; and the upper end of the amplitude-variable rod is connected with the lower end of the high pressure water inlet pipe. The jet pipeline of high pressure water is arranged in the ultrasonic energy converter, so that the device has a compact structure and small volume and cannot interfere with other parts.

Description

technical field [0001] The invention relates to an ultrasonic pulse jet spraying device, in particular to a mid-entry ultrasonic strong resonance pulse jet spraying device. Background technique [0002] Pulse high-pressure water jet technology is a high-tech developed in the 1990s and widely used in industrial cleaning, cutting, deburring, surface coating peeling, rust and paint removal, etc. After more than ten years of rapid development, it has Form unsteady water jet, cavitation water jet, natural pulse water jet, ultrasonic pulse water jet and other major fields. Among them, the ultrasonic pulsed water jet technology can provide discontinuous, or high-frequency pulsed water jets called "bullet beams"; due to the impact force caused by the water hammer phenomenon, the impact force obtained by the high-frequency oscillation pulse of the water jet is amplified The magnification is about 3~5 times. In order to achieve the same cleaning capacity, it only needs to operate wi...

Problems solved by technology

Although this device has good cleaning effect, there are still various problems and shortcomings as follows: 1. The jet pipeline is arranged outside the ultrasonic transducer, which is bulky and easy to interfere; 2. The heat dissipation effect of the ultrasonic transducer is poor, and it is easy to Heat generation affects the stable operation of the ultrasonic transducer
