New high-pressure bubble crushing device

Abstract

The invention discloses a novel high-pressure air bubble crushing device, which comprises a jet, a main cylinder and a cutting device; the outlet end of the jet communicates with the main cylinder; a main shaft is arranged in the main cylinder, and a helical blade is arranged on the main shaft; A high-speed motor is provided on the top of the cylinder, and the output shaft of the high-speed motor is connected to the main shaft; the bottom of the main cylinder is connected to the cutting device, and the cutting device includes a cylindrical shell with a rotating shaft in the center of the cylindrical shell, and the upper end of the cylindrical shell The upper fixed orifice plate is fixedly connected, the lower fixed orifice plate is fixedly connected to the bottom of the cylindrical shell, the upper rotating orifice plate and the lower rotating orifice plate are fixedly connected to the rotating shaft, and the stirring blade is arranged on the rotating shaft; the bottom of the cylindrical shell is fixedly connected with a bottom plate, The base plate is connected with a conveying pipe; each orifice plate is evenly provided with small holes. The invention has low cost, the size of the formed micro-bubbles makes the rising speed consistent with the speed at which oxygen in the bubbles dissolves in water, and the bubbles stay in the water for a long time, thereby achieving the best oxygen-increasing effect.

Description

technical field [0001] The invention relates to a pulverizer, in particular to a pulverizing device for air bubbles in water in fish pond cultivation. Background technique [0002] At present, in pond culture, due to the relatively high density of fish, the lack of oxygen in the fish pond water is extremely unfavorable for fish growth. In the two seasons of summer and autumn, the phenomenon of hypoxia in fish pond water is particularly serious. After the water is hypoxic, the pond will also produce a relatively large odor, which will deteriorate the breeding environment. [0003] In order to cope with the lack of oxygen in the water, it is necessary to increase oxygen in the fish pond. Existing fishpond aeration devices just mechanically stir the fishpond water surface to form larger volume air bubbles. Bubbles can only sink to shallow places below the water surface, and the effect of increasing oxygen in deeper places is not good. At the same time, the bubbles are large i...

AI Technical Summary

Problems solved by technology

Bubbles can only sink to shallow places below the water surface, and the effect of increasing oxygen in deeper places is not good. At the same time, the bubbles are large in size and can easily rise to the surface of the water quickly, so they must be constantly stirred to increase oxygen, which is inefficient. no significant effect

The existing nano-bubble generating devices in the market are expensive

At present, there is a lack of a bubble crushing device with low cost, moderate residence time of bubbles in water (oxygen dissolution time is consistent with the residence time of bubbles in water), and high oxygenation efficiency in fish ponds.
