Description

Technical Field

[0001] This utility model relates to a nanobubble generator. Background Technology

[0002] A bubble generator is a device that disperses gas (usually air, but can also be specific gases such as oxygen and carbon dioxide) into a liquid in the form of bubbles. Its core function is to enhance gas-liquid contact and mass transfer efficiency by generating a large number of bubbles, playing a key role in many fields. Current bubble generators include a shell with a feed section at the front and a discharge section at the rear. Inside the shell is a reaction chamber. Gas can enter the liquid through circumferential air inlets at the feed end of the reaction chamber. By designing the discharge section as a Venturi structure, microbubbles are generated using the high-speed water flow shear at the throat of the Venturi tube and the high-intensity eddy current disturbance on the wall of the diffuser section. However, the Venturi tube at the rear alone cannot guarantee bubble stability. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a nanobubble generator that can ensure bubble stability.

[0004] To achieve the above objectives, one of the technical solutions adopted by this utility model is: a nanobubble generator, comprising a feeding section, a suction section, a mixing section, a secondary diffusion section, and a discharge section, which are sealed at both ends and have through holes inside;

[0005] The through holes of the inlet section from the inlet to the outlet are, in sequence, a first circular smooth section, a first constriction section, a second circular smooth section, a first diffusion section, and a third circular smooth section. The inner diameter of the first circular smooth section is larger than the inner diameter of the third circular smooth section, and the inner diameter of the third circular smooth section is larger than the inner diameter of the second circular smooth section. A through air inlet hole is provided on the outer wall of the inlet section corresponding to the second circular smooth section.

[0006] The through-hole in the mixing section is the second contraction section;

[0007] The secondary diffusion section includes a first diffusion section and a second diffusion section. The outlet end of the first diffusion section is threadedly connected to the inlet end of the second diffusion section. The diffusion angle of the through hole of the first diffusion section is smaller than that of the through hole of the second diffusion section.

[0008] The through hole of the discharge section is a fourth circular smooth part, and the inlet end of the discharge section is threadedly connected to the outlet end of the second diffusion section.

[0009] The beneficial effects of this utility model are:

[0010] The liquid flows through the first circular smooth section, the first contraction section, the second circular smooth section, the first diffusion section, the third circular smooth section, the second contraction section, and then through the first diffusion section and the second diffusion section, finally exiting from the fourth circular smooth section of the discharge section, forming a two-stage Venturi tube. The gas enters from the second circular smooth section with the smallest inner diameter. When the liquid flows inside the Venturi tube, the liquid velocity increases due to the decrease in the cross-sectional area of ​​the flow path. The entire flow must undergo the narrowing process of the channel at the same time, so the pressure also decreases at the same time, thus generating a pressure difference. This pressure difference is used to provide an external suction force for the fluid. The flow path is angled, and the air enters and mixes with the liquid in a rotating manner to form bubbles. The stability of the bubbles is ensured by the cooperation of the two-stage Venturi tube and the two-stage diffusion section.

[0011] Preferably, a first groove and a second groove are respectively provided on both sides of the mixing section;

[0012] The outlet port of the inhalation section engages with the first groove, and the two are sealed by hard friction.

[0013] The inlet port of the first diffuser engages with the second groove, and the two are sealed by hard friction.

[0014] The intake section, mixing section, and secondary diffusion section are connected by grooves and sealed with hard friction, eliminating the need for thread machining and simplifying the process.

[0015] Preferably, the outlet port of the second diffusion section is equipped with a filter screen, the filter screen being 100 mesh. This is used to disperse the bubbles, thus better ensuring the stability of the bubbles.

[0016] Preferably, the filter screen has two layers to further ensure the stability of the bubbles.

[0017] Preferably, it also includes a housing, on which an air inlet pipe is provided;

[0018] The housing is fitted onto the intake section and the secondary diffusion section and is sealed to both respectively. A gap is left between the housing and the intake section and the secondary diffusion section to form a gas chamber.

[0019] Preferably, one end of the housing is threadedly connected to the outer wall corresponding to the first circular smooth portion of the suction section;

[0020] The other end of the housing is threadedly connected to the outer wall of the first diffusion section.

[0021] Preferably, the through hole of the feed section is a fifth circular smooth part, and the inner diameter of the fifth circular smooth part is smaller than the inner diameter of the first circular smooth part. Attached Figure Description

[0035] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0036] See Figures 1 to 6 As shown, this embodiment discloses a nanobubble generator, including a feeding section 10 with sealed ends and through holes, a suction section 20, a mixing section 30, a secondary diffusion section 40, a discharge section 50, and a shell 60.

[0037] Among them, the through hole of the material section 10 is the fifth circular smooth part 11, and the inner diameter of the fifth circular smooth part 11 is smaller than the inner diameter of the first circular smooth part 21.

[0038] The through holes of the intake section 20 from the inlet to the outlet are, in sequence, a first circular smooth part 21, a first contraction part 22, a second circular smooth part 23, a first diffusion part 24, and a third circular smooth part 25. The inner diameter of the first circular smooth part 21 is larger than the inner diameter of the third circular smooth part 25, and the inner diameter of the third circular smooth part 25 is larger than the inner diameter of the second circular smooth part 23. A through air inlet 26 is provided on the outer wall of the intake section 20 corresponding to the second circular smooth part 23.

[0039] The mixing section 30 has a through hole that is a second contraction section 31. The mixing section 30 has a first groove 32 and a second groove 33 on both sides. The outlet port of the suction section 20 is engaged with the first groove 32 and the two are sealed by hard friction. The inlet port of the first diffusion section 24 is engaged with the second groove 33 and the two are sealed by hard friction.

[0040] The secondary diffusion section 40 includes a first diffusion section 41 and a second diffusion section 42. The outlet end of the first diffusion section 41 is threadedly connected to the inlet end of the second diffusion section 42. The diffusion angle of the through hole in the first diffusion section 41 is smaller than that in the second diffusion section 42. The through hole of the discharge section 50 is a fourth circular smooth part 51. The inlet end of the discharge section 50 is threadedly connected to the outlet end of the second diffusion section 42. A filter screen 43 is provided at the outlet port of the second diffusion section 42. The filter screen 43 is 100 mesh and has two layers to further ensure the stability of the bubbles.

[0041] The housing 60 is fitted onto the intake section 20 and the secondary diffuser section 40 and is sealed to both respectively. A gap is left between the housing 60 and the intake section 20 and the secondary diffuser section 40 to form a gas chamber 62. An air inlet pipe 61 is provided on the housing 60. One end of the housing 60 is threaded to the outer wall corresponding to the first circular smooth part 21 of the intake section 20, and the other end of the housing 60 is threaded to the outer wall of the first diffuser section 41.

[0042] The working principle of this embodiment is as follows: the liquid flows at a certain speed from the first circular smooth section 21, the first contraction section 22, the second circular smooth section 23, the first diffusion section 24, the third circular smooth section 25, and the second contraction section 31, then through the first diffusion section 41 and the second diffusion section 42, and finally out of the fourth circular smooth section 51 of the discharge section 50. The liquid passes through two stages of Venturi tubes, while the gas enters from the second circular smooth section 23 with the smallest inner diameter. When the liquid flows in the Venturi tube, the liquid velocity increases because the cross-sectional area of ​​the flow path decreases. The entire flow must undergo the narrowing process of the channel at the same time, so the pressure also decreases at the same time, thereby generating a pressure difference. This pressure difference is used to provide an external suction force for the fluid. The flow channel is angled, and the air enters and mixes with the liquid in a rotating manner to form bubbles. The bubbles are then dispersed again by the filter screen at the tail, ensuring the uniformity and stability of the bubbles, making the contact area with the target substance more stable, avoiding excessively high or low local concentrations, thereby improving the efficiency of purification, reaction, or action.
