Description

Technical Field

[0001] The present invention belongs to the technical field of air flotation separation, and specifically relates to an air flotation foam collection structure, a mineral powder flotation device, an aquaculture device, and a water purification device. Background Art

[0002] Air flotation separation is a technology that uses bubbles to adsorb and float out substances in a liquid, and is commonly used in fields that require substance separation such as water purification, waste liquid purification, extraction of microorganisms in water, extraction of organic substances in water, aquaculture purification, or mineral powder flotation;

[0003] Air flotation separation can directly separate and discharge organic substances in sewage and wastewater using air and electricity, and has the advantages of environmental protection, speed, and simplicity of implementation. The inventor believes that air flotation will surely shine in human production and life in the future, so the inventor has been researching in this field for many years.

[0004] The prior art collects air flotation foam by discharging it through methods such as accumulation and discharge in a cavity, scraping and collecting and discharging, etc.; Accumulation and discharge in a cavity has the advantage of relatively small equipment used; However, it accumulates and discharges the de-liquefied and concentrated dry foam in a fixed open cavity; There are the following technical problems:

[0005] Technical Problem 1: During the foam de-liquefaction process, the pressure on the contact surface between the foam and the atmosphere is fixed at atmospheric pressure, resulting in the pressure on the upper side of the liquid film being mainly atmospheric pressure. The force of the pressure de-liquefaction effect is limited, and there is room for improvement in the foam de-liquefaction speed;

[0006] Technical Problem 2: Since the foaming degree of different liquids is different, the height of the foam column accumulated in the accumulation cavity is different. Facing liquids with a large amount of foaming substances, it is necessary to reduce the air flow rate on-site to reduce the height of the foam column in order to ensure a high degree of de-liquefaction of the discharged dry foam. However, air flotation relies on bubbles to adsorb substances. Reducing the air flow rate means that the amount of substances adsorbed by bubbles per unit time becomes less, reducing the amount of substances separated per unit time and reducing the separation efficiency; In the case of the same liquid, the upper limit of the applicable air flow rate is restricted by the height of the foam accumulation tube; In the case of the same air flow rate, the upper limit of the adaptation range of the liquid foaming substance concentration is restricted by the height of the foam accumulation tube; There is room for improvement in the adaptability to liquids; If the upper limit is to be increased, the foam accumulation tube needs to be enlarged or lengthened, increasing the harshness requirements for the installation environment; There is room for improvement in space adaptability.

[0007] In summary, it can be seen that in the prior art, there is room for improvement in de-liquefaction speed and applicability. Summary of the Invention

[0008] In order to solve Technical Problem 1 or Technical Problem 2, the following technical solutions are proposed.

[0009] A1. Air flotation foam collection structure, including a foam accumulation pipe (1), and its advantages are as follows: it includes a regulating valve (2); the regulating valve (2) has an a end and a b end; the a end is hermetically connected to the foam accumulation pipe (1), and the b end communicates with the atmosphere; the discharge path of the foam or the gas released by the bursting of the foam in the foam accumulation pipe (1) passes through the regulating valve (2).

[0014] A6. Based on A1, its advantages are as follows: the regulating valve (2) is an electronically controlled regulating valve.

[0015] A7. Based on A1, its advantages are as follows: the connection between the a end and the foam accumulation pipe (1) is a movable seal connection.

[0017] Technical principle: During use, according to the actual application environment and usage requirements, operate the regulating valve (2) to change the inner diameter of the fluid passage of the regulating valve (2), thereby adjusting the air pressure in the foam accumulation pipe (1), so that the pressure on the liquid film is appropriately increased. Without reducing the gas flow rate of the bubble generation device, the height of the foam column can be reduced; the pressure on the liquid film increases, accelerating the liquid separation speed; the applicability to liquids is enhanced; without changing the size of the foam accumulation pipe (1), the upper limit of the gas flow rate and the upper limit of the liquid foaming degree can be increased, and the applicability to the installation space is also enhanced. Beneficial effects

[0018] 1. It provides a new technical idea for adjusting the internal pressure of the foam accumulation pipe (1) to accelerate the liquid separation speed.

[0022] 5. The height of the foam column is reduced, and the applicability to the installation space is also enhanced.

In summary, the present invention provides multiple new ideas, low cost, faster liquid drainage speed, can control the height of the foam column without controlling the air flow rate of the air pump, has better applicability, and achieves multiple beneficial effects with a simple structure, and the design is concise and ingenious.
