Abstract
The utility model provides a two-phase flow shock wave highly effective surface treatment device which relates to the object cleaning or derusting device. A fluid feed mechanism, a coupling tube, an adjustable valve and a shock wave generator are fixed connected in order to form the utility model. The injection lumen of the shock wave generator is communicated with an air hole which is arranged on the outer surface of the injection lumen. When the fluid feed mechanism is started, the air can be injected to form supersonic flow in the shock wave generator in order to produce shock wave effect and cavitation effect. The utility model can be applied to the cleaning, derusting and other surface treatment of the surfaces of apparatus, equipment, roads, walls, etc. The utility model has the characteristics of simple structure, easy usage, power saving, water conservation, environmental protection and high efficiency. The fluid pressure and flow quantity are adjustable. The utility model can be widely used in the fields of chemical industry, energy resource, architecture, traffic, and environmental protection.
Description
Technical field:
The utility model relates to the cleaning or the derusting device of body surface, is applicable to chemical industry, the energy, building, traffic, environmental protection field.
Background technology:
At present the target pursued of surface processing device is energy-conservation, water saving and high efficiency.By literature search, find that existing patented technology addresses the above problem attempting, but result's imperfection all.As domestic utility model patent 97220377.X, its name is called " high pressure aqueous vapor cleaning machine ", is made up of air compressor, water storage tank, give vent to anger pipeline and regulating gate, and as cleaning power, injection water formation two-phase flow is cleaned with compressed air.This cleaning machine is owing to need air compressor, water storage tank, complex structure, and range of application is restricted, and fluid pressure is lower, and efficient is low, power consumption.
Summary of the invention:
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, provide a kind of two phase flow shock wave efficient surface processing device, this device forms the mobile and generation shock wave of two-phase supersonic speed with pressure fluid injection air, finish processing by shock-wave effect and cavitation effect to body surface, water-saving and environmental protection not only, fluid pressure and flow are adjustable, and simple structure, the efficient height, power saving.
In order to realize the purpose of above-mentioned utility model, its technical scheme is, this device is sealedly and fixedly connected successively by fluid supply mechanism, junction pipe, control valve and shock wave generator, on the surface at the ejection cavity place of shock wave generator, the pore that communicates with this ejection cavity is arranged, utilize shock-wave effect and cavitation effect, carry out surface treatment.
The utility model compared with prior art, its technique effect is that simple in structure, the commute treatment surface can directly utilize running water to handle, and is easy to use; Utilize water and air as working media, can not pollute clean environment firendly environment; Fluid flow and adjustable in pressure; Utilize the characteristics of the low velocity of sound of two phase flow, the design shock wave generator realizes that the two-phase supersonic speed flows and produces shock wave, finishes processing to body surface by shock-wave effect and cavitation effect, and efficient is higher, economizes on electricity more, economizes on water, applied range.
