Description

TECHNICAL FIELD

[0001] The present application belongs to the field of air floatation treatment, and particularly relates to a bubble stacking tube and an air floatation separation device. BACKGROUND

[0002] In the industrial fields of sewage treatment, mineral flotation, aquatic plant feeding, etc., air floatation technology is an important separation and enrichment method, and the generation and stabilization of bubbles play a key role in the separation of target substances.

[0003] The conventional bubble stacking tube adopts a single space channel to stack bubbles, and relies on the gap between the bubbles to remove liquid. When the bubbles break, the interference waves generated will spread, causing the adjacent bubbles to break or deform, damaging the liquid removal process, reducing the liquid removal effect of a single bubble, and affecting the bubble floatation liquid removal efficiency; the liquid removed from the upper bubbles of the conventional bubble stacking tube will be absorbed by the lower bubbles, resulting in low liquid removal efficiency; therefore, the conventional bubble stacking tube needs to be improved. SUMMARY

[0004] The present application aims to provide a bubble stacking tube capable of effectively reducing the interference diffusion of bubble burst, thereby significantly improving the liquid removal efficiency.

[0005] The bubble stacking tube (1) has the following design highlights: it contains multiple small tubes (2) inside; the top of the small tubes (2) is lower than the top of the bubble stacking tube (1), and the space between the tops of the two forms a bubble observation cavity (3); the small tubes (2) are circular tubes, and at least three small tubes (2) form a gap (4) with the outer walls of the small tubes as the boundaries.

[0006] Further, the material of the small tubes (2) is plastic, glass, metal or ceramic.

[0007] Further, the material of the small tubes (2) is a composite material.

[0008] Further, the inner diameter of the small tubes (2) is between 9 mm and 11 mm.

[0009] Further, the small tubes (2) are fixed by the friction force of the outer wall contact.

[0010] Further, the bubble stacking tube (1) is composed of multiple or single components.

[0011] Further, the small tubes (2) are shorter than the bubble stacking tube (1).

[0012] Further, the small tubes (2) are deformable and can be squeezed and deformed.

[0013] The air floatation separation device has a bubble stacking tube, and the design highlights of the bubble stacking tube are as follows: the bubble stacking tube is the aforementioned bubble stacking tube.

[0014] Working principle: A1, during air floatation, the bubbles carrying target substances rise in the bubble stacking tube to remove liquid. The principle of the bubble stacking tube of the present application is as follows:

[0015] The rising foam is divided into independent micro spaces by the internal small tubes. When a certain bubble breaks, the energy is released in the small tube enclosed area, the small tube absorbs and disperses the energy, prevents the wave from spreading, limits the interference range, stabilizes the foam group and the liquid extraction process, and improves the liquid extraction efficiency.

[0016] A2, the foam in the traditional bubble tube is disturbed and cannot be fully extracted. The bubble tube of the present application reduces interference, so that the foam can be extracted within a stable time period. The liquid is orderly extracted under the action of gravity and other factors and flows down along the inner wall. This stable and efficient liquid extraction improves the overall efficiency, reduces the air flotation time and energy consumption, and enhances the economic efficiency and practicality of the air flotation process.

[0017] A3, the top of the small tube (2) is lower than the top of the bubble tube (1) to form a foam observation cavity (3), which facilitates observation of the foam consistency.

[0018] A4, the small tube (2) is a circular tube and the outer wall is in contact, the gap cross-sectional area is smaller than the tube cavity cross-sectional area and the corner is sharp, the air resistance is large, so that the liquid extracted in the foam observation cavity (3) preferentially flows back from the gap, reducing the difficulty of liquid extraction and improving the efficiency.

[0019] A5, the circular tube is stable and mature in production and inexpensive, and the present application uses it to construct a liquid extraction and backflow separation structure, which is easy to process and low in cost. Advantages

[0020] A new technical idea for improving the liquid extraction efficiency of air flotation foam is provided.

[0021] Improve the liquid extraction efficiency: by limiting the interference of bubble rupture and optimizing the liquid extraction path, the foam can stably and orderly complete the liquid extraction process, significantly improving the overall liquid extraction efficiency.

[0022] Simple structure: the bubble tube is mainly composed of a plurality of small tubes, the overall structure is clear and easy to understand and implement.

[0023] Easy to process: the commonly used circular tube is used as the basic building block, and its production process is mature. The required structure is formed by simple combination of the circular tubes, which is low in processing and manufacturing difficulty and convenient for production.

[0024] Low cost: the circular tube itself is low in cost, and the whole device structure is simple, without the need for special materials or complex processing procedures, thereby effectively controlling the production cost and having high economic efficiency.

[0025] Convenient to use: in actual application, the bubble tube and air flotation separation device are convenient to operate, easy to install, maintain and integrate into the existing air flotation treatment system, and convenient for users to use.

[0026] In summary, the present application improves the efficiency of liquid removal, has simple structure, is easy to process, low in cost, and convenient to use, and provides a new idea. BRIEF DESCRIPTION OF DRAWINGS
