Problems solved by technology

At present, most of the microbubble generators used in the above fields have complex structures, some require additional water pumps, and some require multiple valves to control. At the same time, there are many restrictions on the way of entering the water, resulting in high costs.
Among them, the setting of the cavitation part of the micro-bubble generator not only occupies a large volume, but also has an unreasonable structure, and it is very inconvenient to install and manufacture.

Embodiment 1

[0075] Such as Image 6 As shown, under the premise of the same structure, changing the diameter d1 of the throat 252 of the cavitation element 2, the microbubble water obtained by the cavitation element 2 is different under each parameter selection range. When the diameter d1 of the throat pipe 252 is selected as 0.2-0.5mm, the water changes from transparent color to rich floating white color, thus it can be inferred that the content of microbubbles in the water is high. When the diameter d1 of the throat pipe 252 is selected to be 0.5-2mm, the water will keep a rich floating white color. From this, it can be inferred that the content of microbubbles in the water is still high, and the water velocity of the cavitation part 2 is applicable in this interval. When the diameter d1 of the throat pipe 252 is chosen to be less than 0.2mm, the flow rate of the water flow through the cavitation element 2 is too small, which is no longer applicable. However, when the diameter d1 of t...

Embodiment 2

[0077] Such as Figure 7 As shown, under the premise of the same structure, changing the multiple of the diameter d2 of the end of the tapered section 251 and the diameter d1 of the throat pipe 252 in the cavitation part 2, the experiment found that under the conditions of different multiples, the water production of the cavitation part 2 The microbubble content is different. When the multiple of the end diameter d2 of the tapering section 251 and the diameter d1 of the throat 252 is less than 1.05, the water is clear, and it can be inferred that the microbubble content in the water is too small. And when the diameter multiple is 1.05-1.3, it can be inferred from the color of the water that the content of microbubbles in the water increases significantly. Especially when the diameter multiple exceeds 1.3, the prepared water is rich and floating white, indicating that the content of microbubbles in the water is very high.

[0078] Under the same structural premise, similar ex...

Embodiment 3

[0080] Such as Figure 8 As shown, changing the cavitation element 2 under the same structural premise, it can be seen that when the ratio of the length L2 of the divergent section 253 to the length L1 of the tapered section 251 changes, the bubble-making effect will also change significantly.

[0081] After the bubbles are generated in the throat pipe 252, if the gradient of the diverging section 253 changes too much, the generated bubbles are very easy to burst. Therefore, if the length ratio of the diverging section 253 and the tapering section 251 is less than or even equal to 1:1, a large number of bubbles will Immediately after it is produced, it is destroyed, so the concentration of air bubbles in the water is not high. When the length ratio of the diverging section 253 and the converging section 251 is between 1-4, the produced water is rich and floating white, and the air bubble content in the water is very high. When the length ratio of the diverging section 253 to ...

Abstract

The invention discloses a cavitation piece of a micro-bubble generator, the micro-bubble generator and a washing device. The cavitation piece has a cavitation inlet and a cavitation outlet for water flow enters and exits; at least one Venturi channel extending from the cavitation inlet toward the cavitation outlet is defined in the cavitation piece; each Venturi channel, in the water flow direction, sequentially comprises a tapered section, a pipeline and an expanding section; the flow area of the tapered section gradually decreases in the direction from the cavitation inlet to the pipeline, the flow area of the expanding section gradually increases in the direction from the pipeline to the cavitation outlet, and the diameter of the pipeline is 0.2-2.0 mm. The cavitation piece provided bythe invention can guarantee the foaming capacity of the cavitation piece and can control the moderate flow rate on the one hand, and has a simple structure, convenient processing and easy cost controlon the other hand.
