Description

Technical Field

[0001] The present invention belongs to the field of air flotation separation, and particularly relates to a design method of an air flotation bubble stacking tube, an air flotation bubble stacking tube, and an air flotation separation 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; Air flotation separation can directly separate and discharge pollutants in sewage and wastewater by using air and electricity, and has the advantages of environmental protection, speed, and simple implementation. Based on the judgment of the broad application prospects of air flotation technology, the inventor has been committed to the research and improvement in this field for a long time.

[0003] In an air flotation device, the bubble stacking tube is one of the key components, mainly used for aggregating or stacking air flotation bubbles.

[0004] In existing air flotation devices, the bubble stacking tube usually has a simple straight tube structure, and does not consider the coupling effect between foam, water body, and upward disturbance. As a result, in situations such as water level fluctuations and sudden increase in pollutants, problems such as too dilute discharged liquid and excessive foam disturbance, that is, the problem of low anti-explosion and impact resistance, are likely to occur, thereby weakening the sewage discharge effect and system stability.

[0005] The bubble stacking tubes in the prior art are all simple tube cavities, resulting in existing air flotation devices having low anti-explosion and impact resistance and having room for improvement. Summary of the Invention

[0006] In order to increase the anti-explosion and impact resistance, the present invention provides a design method of an air flotation bubble stacking tube, an air flotation bubble stacking tube, and an air flotation separation device.

[0007] The design method of the air flotation bubble stacking tube is excellent in that it is designed for an air flotation bubble stacking tube with a separation structure. At the lower end of the separation structure (2), a buffer tube cavity (1) is designed. The upper end of the buffer tube cavity (1) communicates with the lower end of the separation structure (2), and there are at least two water storage areas (a) at different heights in the buffer tube cavity (1).

[0008] 2. The air flotation bubble stacking tube is excellent in that it includes a buffer tube cavity (1) and a separation structure (2) The separation structure (2) is used for separating and treating pollutants and moisture contained in foam or a single-layer foam film; The upper end of the buffer tube cavity (1) communicates with the lower end of the separation structure (2); there are at least two water storage areas (a) at different heights in the buffer tube cavity (1).

[0009] Furthermore: The water storage area (a) described in 1 or 2 is formed by a constriction inside the buffer tube cavity (1).

[0010] Further: The water storage area (a) described in 1 or 2 is formed by an annular constriction inside the buffer lumen (1).

[0011] Further: The number of the water storage areas (a) described in 1 or 2 is greater than 3.

[0012] Further: The water storage area (a) described in 1 or 2 is formed by a groove protruding outward on the wall of the buffer lumen (1).

[0013] Furthermore: The groove is annular.

[0014] Even further: The height of the annular groove is less than 2 mm.

[0015] Further: The separation structure (2) described in 1 or 2 further has a trumpet-shaped lumen (3) that is wider at the top and narrower at the bottom.

[0016] Further: The separation structure (2) described in 1 or 2 further has a collection tube (5).

[0017] Further: The separation structure (2) described in 1 or 2 is a porous separation structure, a slit separation structure, a translation separation structure, a vertical separation structure, an explosion separation structure, etc., which are structures for separating pollutants and moisture in air flotation foam or a single-layer bubble film; Porous separation structure: Foam or a single-layer bubble film passes through a slit to achieve the separation of pollutants and moisture.

[0018] Slit separation structure: Foam or a single-layer bubble film passes through a slit to achieve the separation of pollutants and moisture.

[0019] Translation separation structure: Foam or a single-layer bubble film achieves the separation of pollutants and moisture during horizontal movement; such as a surface-absorbing protein separator and a scraper-type air flotation separator.

[0020] Vertical separation structure: Foam or a single-layer bubble film achieves the separation of pollutants and moisture during vertical movement; such as: CN202110662089.8, a protein separator with an ultraviolet sterilization function.

[0021] Explosion separation structure (which can also be called a membrane rupture and release separation structure): When the bubble film is compressed and ruptured, the gas-water separation is accelerated, and the moisture and pollutants are instantaneously separated when the bubble film ruptures; such as: CN202223218555.2, a freshwater protein separator for aquaculture, mentioned poly-bubble component 46.

[0022] 3. An air flotation separation device having a bubble stacking tube, and the excellent design lies in that: the bubble stacking tube is the aforementioned air flotation bubble stacking tube.

[0023] Further: At least 1 water storage area (a) is higher than the water level (SP).

[0024] 4. Water purification device with an air flotation device, and the excellent design lies in that the bubble stacking tube is the aforementioned air flotation separation device.

[0025] Principle: Furthermore, at least one water storage area (a) is higher than the water level (SP).

[0026] Working principle: The water storage area (a) stores the water separated from the upper foam or single-layer foam film. The water is stored in the water storage area (a) and is strongly absorbed by the lower foam or single-layer foam film. Through the setting of the water storage area (a) in the buffer tube cavity (1), the water separation amount of the foam or single-layer foam film can be reduced during the passing process, thereby reducing the water separation speed of the rising foam or single-layer foam film in the buffer tube cavity (1); making the water separation ability of the buffer tube cavity (1) very weak, and the foam or single-layer foam film can easily pass through the buffer tube cavity; and then enter the separation structure (2) for water separation. Since the buffer tube cavity has little influence on the concentration of the foam or single-layer foam film entering the separation structure (2).

[0027] When the water level rises or the pollutant content suddenly increases, the water bubble mixture rises and first enters the space of the buffer tube cavity (1). The concentration change of the foam or single-layer foam film entering the separation structure (2) is very small. Therefore, the explosion impact failure caused by the rising water level can be reduced.

[0028] To put it simply, the present invention improves the anti-explosion impact ability by reserving space for water bubbles.

[0029] Beneficial technical effects: The present invention provides a buffer tube cavity (1) with very weak water separation ability for the foam or single-layer foam film below the separation structure (2), providing an explosion impact buffer space and a new technical idea for improving the anti-explosion impact ability of air flotation separation.

[0030] The structure is simple and easy to use, and the anti-explosion impact ability of air flotation separation is improved.

[0031] Discussion on creativity: The closest prior art 1 is: CN202510227700.2, low-resistance collection tube for air flotation device, protein separator.

[0032] Distinguishing features: In prior art 1, the low-resistance structure of the low-resistance collection tube is arranged above the separation structure (2); while in the present invention, the low-resistance structure is arranged below the separation structure (2), specifically realized by the structure on the buffer tube cavity (1).

[0033] Differences in technical purposes: The purpose of prior art 1 is to reduce the flow resistance during the sewage discharge process; while the present invention solves the problems of low anti-explosion impact ability in the prior art and easy system failure due to water level changes or pollutant content fluctuations.

[0034] Differences in the mechanism of action: In the prior art 1, the function of the low-resistance structure is to reduce the pulling resistance during the rise of the foam, so as to smoothly guide the foam into the dehydration section; while in the present invention, the low-resistance structure arranged below the dehydration section mainly provides a buffer space for the foam and water mixture, which is used to absorb sudden impacts and improve the system stability.

[0035] Differences in technical effects: The technical effect achieved by the low-resistance structure in the prior art is smooth sewage discharge; while the low-resistance structure of the present invention brings a new and unexpected technical effect of "improving the anti-explosion and impact resistance ability", with a significant functional transformation.

[0036] C1: In the prior art 1, the low-resistance collection pipe is arranged at the upper end of the separation structure (2), and the effect is to smoothly guide the foam or foam film to dehydrate and discharge; while the present invention arranges the low-resistance structure below the separation structure (2). By recombining two known elements (the low-resistance structure and the dehydration cavity), an unexpected technical effect of "improving the anti-explosion and impact resistance ability" is achieved, which belongs to the

non-obvious combination invention

[0037] C2: By adjusting the low-resistance structure from "above" to "below", the present invention changes its spatial configuration relationship with the separation structure, so that the function of the low-resistance structure changes from "sewage discharge assistance" to "buffer stability", and an unexpected technical effect of "improving the anti-explosion and impact resistance ability" is achieved, which belongs to the

invention with changed element position relationship

[0038] C3: The present invention not only changes the spatial relationship between the low-resistance structure and the dehydration section, but also realizes a fundamental change in the function - from "reducing the pulling resistance of the foam" to "providing an impact buffer space". This change in the mechanism of action brings an essential directional change in the technical effect, and an unexpected technical effect of "improving the anti-explosion and impact resistance ability" is achieved, which belongs to the

invention with changed element function relationship

[0039] C4: Using the low-resistance structure to improve the anti-explosion and impact resistance ability solves completely different problems, which cannot be deduced by a person skilled in the art, a virtual person, based on the prior art, and meets the requirements of creativity described in Article 5.3 of Chapter 4 of Part II of the "Patent Examination Guidelines", and has creativity.

[0040] C5: This virtual person, an ordinary person skilled in the art, has limited thinking due to the settings and has no ability to change the technical purpose. In the prior art, the technical effect of the low-resistance structure is to discharge sewage smoothly, while the technical effect of the present invention using this structure to improve the anti-explosion impact ability is completely different. This belongs to the situation of reusing the decoupling of technical means and purpose and is not within the scope reasonably foreseeable by a person skilled in the art based on the original structure, thus possessing creativity.

[0041] C6: The present invention uses the low-resistance structure originally used for smooth sewage discharge to provide a buffer space for explosion impact and achieves the unexpected technical effect of "improving the anti-explosion impact ability". This belongs to the typical type of "invention of new uses of known products" described in Paragraph 4.5-(2) of Chapter 4, Part II of the "Patent Examination Guidelines" and possesses creativity.

[0042] C7: Using the low-resistance structure of foam or bubble film as a buffer space belongs to "a technical solution with different technical concepts" and achieves the unexpected technical effect of "improving the anti-explosion impact ability", meeting the requirements for creativity in the "Patent Examination Guidelines" and possessing creativity.

[0043] C8: The prior art does not provide any technical inspiration for using the low-resistance structure in the "anti-explosion impact" scenario. The present invention expands the applicability of this structure in different problems based on structural reconfiguration, belonging to a non-obvious solution lacking technical inspiration and possessing creativity.

[0044] C9: Solved the technical problem of "low anti-explosion impact ability" that people have been eager to solve and possesses creativity.

[0045] Note that the creative support arguments C1–C9 are independent and parallel judgment paths. Each one quotes different articles in the "Patent Examination Guidelines" and each one can independently support the establishment of creativity, and it is not required that they all hold simultaneously. Therefore, when examining the creativity of the present invention, the sufficiency of each reason should be evaluated separately. If any one of the reasons holds, the present invention should be determined to meet the requirements for creativity; even if an individual argument is not adopted, as long as any one of them holds, it should be determined that the present invention possesses creativity.

[0046] The present invention realizes a technical solution with a simple structure but prominent effects through the re-matching of structural configuration and usage logic, meeting the substantial requirements of "non-obviousness" in Article 22, Paragraph 3 of the "Patent Law" and should be determined to possess creativity.

[0054] Embodiment 1, as shown in Figure 1 and 2 shown, the air flotation bubble tube contains a separation structure (2), and the excellent design lies in: it also includes a buffer lumen (1); the upper end of the buffer lumen (1) communicates with the lower end of the separation structure (2); there are at least two water storage areas (a) at different heights on the wall of the buffer lumen (1). The water storage area (a) is formed by a constriction inside the buffer lumen (1). The separation structure (2) is a vertical separation structure. In fact, it is a tube. When the foam or single-layer bubble film rises in the tube, the water flows downward and is recovered under the action of gravity. Under the action of air pressure, the dehydrated foam or single-layer bubble film continues to rise and is discharged.

[0055] Embodiment 2, as shown in Figure 3 shown, the air flotation bubble tube, on the basis of Embodiment 1, the separation structure (2) also has a flared tube cavity (3) with a large upper part and a small lower part as an explosion separation structure, and also has a collection chamber (4). After the dehydrated foam or single-layer bubble film enters the collection chamber (4) in the separation structure (2), it is discharged.

[0056] Embodiment 3, as shown in Figure 4 shown, the air flotation separation device, different from Embodiment 1, the top of the separation structure (2) also has a collection tube (5) for collecting and discharging the dehydrated foam or single-layer bubble film.

[0057] Embodiment 4, as shown in Figure 5 shown, the air flotation separation device is composed of the air flotation bubble tube of Embodiment 2, an air pump (B) and an air stone (Q). The air pump (B) supplies air to the air stone (Q) through an air pipe to generate bubbles.

[0058] Embodiment 5, as shown in Figure 6 shown, the air flotation bubble tube, different from Embodiment 1, the water storage area (a) is formed by an outwardly convex annular groove on the wall of the buffer lumen (1).

[0059] Others: Although the present invention is simple, its design is ingenious. By changing the positions and combination manners of known structures, unexpected beneficial effects are produced. Achieving good beneficial effects with a simple design is exactly the manifestation of the exquisite design of the present invention. Readers should judge the inventiveness of the present invention from multiple dimensions, such as whether the technical problem has been proposed, whether the technical solution has emerged, and whether the technical effect has been produced, rather than relying on hindsight thinking to deny the inventiveness of the present invention on the grounds that the present invention is simple. It should be noted that simplicity does not mean easy to conceive. The technical inspiration must closely follow the content disclosed in the prior art and be analyzed in combination with the ability limitation of the virtual person, those skilled in the art, defined by the Patent Law. Although the structure of the present invention is simple, it solves long-existing technical problems. Its inventiveness should be judged based on the objective absence of technical inspiration rather than relying on subjective assumptions.
