Multifunctional foam generator

Abstract

The invention discloses a multifunctional foam generator made of metal. The multifunctional foam generator comprises a liquid preparation part and a gas mixing part. The liquid preparation part sequentially comprises a water inlet end, a medicine inlet section and a foam generation section from left to right. A water-medicine mixing hole is formed in the center of the liquid preparation part and comprises a water inlet threaded hole, a conical shrinkage cavity, a water-medicine mixing straight hole and a mixing hole. The gas mixing part sequentially comprises a gas inlet end, a mixing sectionand a water outlet end from left to right. The center of the gas mixing part consists of three cylindrical holes, namely a liquid-gas mixing hole, a transition hole and a water outlet threaded hole insequence from left to right. The foam generation section of the liquid preparation part is inserted into the liquid-gas mixing hole of the gas mixing part, and the right end surface of the medicine inlet section of the liquid preparation part and the left end surface of the gas inlet end of the gas mixing part are closely attached and welded into a whole. The multifunctional foam generator can use various kinds of liquid medicine at the same time, the sealing performance is good, air, the liquid medicine and water are fully mixed, and foam is uniform and rich.

Description

technical field [0001] The invention relates to a foam mixed liquid generating device, in particular to a multifunctional foam generator for high-pressure cleaning equipment used in workplaces of food and drug industries. Background technique [0002] High-pressure cleaning equipment is widely used to clean courtyards, buildings, vehicles, workplaces, etc. In order to achieve better cleaning results, it is generally necessary to spray the cleaning objects with foam, and to disinfect the cleaning objects in workplaces such as food and drug industries. Liquid foam for disinfection. A foam generator is a device used to generate foam. It sucks cleaning or disinfecting liquid (hereinafter referred to as liquid medicine) and air into the pipeline through the principle of Venturi effect, and fully mixes it with water in the pipeline. Whether the foam is rich or not depends on the mixing ratio of air, liquid medicine and water, and whether they are fully mixed. [0003] Chinese pa...

AI Technical Summary

Problems solved by technology

[0005] However, there are still some defects in the existing foam generators. The one is that the liquid medicine is single, and only one kind of liquid medicine can be used at a time, such as cleaning liquid; First, the pressure of each flow channel in the foam generator is unstable, and the foam is uneven and rich; third, the design of the flow channel is unreasonable, so that the liquid medicine, air and water cannot be fully mixed, less foam occurs, and the cleaning effect is poor
