Description

Technical Field

[0001] This invention belongs to the field of water purification, specifically relating to air flotation foam collection pipes, water purification equipment, and aquatic organism breeding equipment. Background Technology

[0002] Air flotation is a technology that uses air bubbles to adsorb and float pollutants in water. It is commonly used for wastewater purification and aquaculture purification. The characteristic of air flotation is that the more foaming substances in the water, the more foam is produced and the faster the purification speed of air flotation. Conversely, the less foaming substances in the water, the slower the purification speed. As a result, air flotation has a very weak purification ability for water bodies with fewer large molecules.

[0003] To enhance the purification capacity of air flotation, the following three methods are generally selected to improve the purification effect: 1. Adding chemicals to the water; for example, Chinese invention patent, [Invention Authorization] CN201610200211.9 An integrated ultra-micro air flotation purification system and its method for purifying landscape water bodies; a reaction zone is set up for chemical reaction; While adding chemicals is highly effective, it is not suitable for many situations where adding chemicals is not allowed, and it is also costly.

[0004] Increasing the power of microbubble machines (such as micro / nano air pumps, micro / nano cutters, and needle brush pumps) generates more microbubbles; for example, Chinese invention patents CN202110960514.1, a charged micro / nano bubble suspension jet machine based on heated cutting method; and CN202010770935.3, a wastewater flotation treatment method. The effect is significant, but it consumes a lot of energy, is easily damaged, and has a high cost.

[0005] The diameter of the foam collection tube gradually decreases from bottom to top; for example, the protein separator authorized by CN202010733764.7 is easy to adjust; the effect is significant, but the pipeline is fixed and when the accumulated foam is relatively high, it is necessary to adjust it by a small amount to prevent the foam water content from being too high, which would result in the loss of the number of bubbles, reduce the adsorption scale, and have poor adaptability.

[0006] In conclusion, while prior art has many advantages, it still suffers from technical problems such as poor adaptability, high energy consumption, vulnerability, and high cost, and therefore needs to be improved. Summary of the Invention

[0007] To address the aforementioned technical problems, the present invention proposes the following technical solutions: The advantages of the air flotation foam collection tube are: it includes a foam stacking tube (1) and a collection tube (2). The inner diameter of the bubble collection tube (1) is larger than the outer diameter of the collection tube (2); The bottom of the bubble tube (1) is open and the top is closed; The upper end of the collection tube (2) is located outside the bubble tube (1), and the lower end of the collection tube (2) is located inside the bubble tube (1). The lower end of the collection tube (2) is lower than the upper end of the bubble tube (1). The collection tube (2) can move up and down.

[0008] Furthermore, the collection tube (2) and the bubble tube (1) are connected by a movable seal.

[0009] Furthermore: the collection tube (2) and the bubble tube (1) are connected by a sliding connection, and the collection tube (2) can slide up and down relative to the bubble tube (1).

[0010] Furthermore: the collection tube (2) and the bubble tube (1) are connected by a thread, and rotating the collection tube (2) causes the collection tube (2) to move up and down.

[0011] Furthermore: the lower end of the collection tube (2) is a trumpet-shaped opening that is larger at the bottom and smaller at the top.

[0012] Further: the collection tube (2) and the bubble tube (1) are coaxial.

[0013] Furthermore: the collection tube (2) is a straight tube.

[0014] Furthermore: the collection tube (2) and the bubble tube (1) are fixedly connected, and the bubble tube (1) can extend and retract up and down, driving the collection tube (2) to move up and down.

[0015] Furthermore: the bubble tube (1) includes a first section (1-1) and a second section (1-2); the first section (1-1) and the second section (1-2) are coaxial; the second section (1-2) is fitted outside the first section (1-1); the first section (1-1) and the second section (1-2) can slide along the axis to achieve vertical extension and retraction.

[0016] Furthermore: the bubble tube (1) includes a first section (1-1) and a second section (1-2); the first section (1-1) and the second section (1-2) are coaxial; the first section (1-1) is fitted outside the second section (1-2); the first section (1-1) and the second section (1-2) can slide along the axis to achieve vertical extension and retraction.

[0017] Furthermore: the bubble tube (1) is a serpentine tube that can be extended up and down.

[0018] Furthermore: the upper part of the collection tube (2) has a sludge collection chamber (JWQ), and the sludge collection chamber (JWQ) has a sludge discharge channel (PWTD). The upper end of the collection tube (2) is located inside the sludge collection chamber (JWQ), and the upper end of the sludge collection chamber (JWQ) is higher than the sludge discharge channel (PWTD).

[0019] The water purification equipment has an air flotation water purification device, and its advantage lies in the fact that the air flotation purification device has the aforementioned air flotation foam collection pipe.

[0020] This aquatic organism breeding and cultivation equipment includes an air flotation water purification device. Its superior feature is that the air flotation purification device has the aforementioned air flotation foam collection pipe. It is used for planting aquatic plants or raising aquatic animals.

[0021] Principle: When the foam column rises, the foam with less water content in the middle of the foam column (relative to the outside of the foam column) is pushed into the collection tube (2), and the foam collected by the collection tube (2) rises and is discharged under the push of air pressure. Beneficial effects

[0022] Using the collection tube (2) to directly collect and discharge foam with high pollutant content in the center of the foam column, reducing the water content of the foam, this innovative new technical approach has reached the level of advanced technology.

[0023] Compared to the previous method of squeezing foam from the edge to the center, the present invention has higher sewage discharge efficiency, and the discharged foam has lower water content and higher concentration.

[0024] By changing the position of the lower end of the collection tube (2), it can adapt to different water quality conditions. By adjusting the height of the collection tube, it is convenient to set the state required by the user. It is convenient, easy to use, simple, inexpensive and not easily damaged.

[0025] The collection tube (2) can move up and down, adapting to different water quality conditions. When the water quality improves, the amount of foaming substances in the water decreases, and the height of the foam column that can be accumulated is low. Lowering the height of the lower end of the collection tube will allow for continued sewage discharge and further improvement of water quality. It has the beneficial effect of good adaptability.

[0026] This invention improves water purification efficiency without requiring additional energy consumption, thus having the beneficial effect of energy saving.

[0027] In summary, this invention is convenient, easy to use, simple, inexpensive, durable, adaptable, energy-saving, and pioneers a new technical approach. Attached Figure Description
