Description

Technical Field

[0001] This invention relates to the field of liquid bubble aeration technology, and more particularly to a swirl aeration device. Background Technology

[0002] Liquid bubble aeration is an engineering technology that involves introducing gas into a liquid to generate a large number of bubbles. The gas within the bubbles exchanges substances with the liquid, thereby increasing the concentration of dissolved gases (such as oxygen, carbon dioxide, chlorine, and ozone) in the liquid. Liquid bubble aeration is widely used in aquaculture, disinfection and sterilization, chemical production, wastewater treatment, and many other fields.

[0003] Existing static porous aerators typically rely on at least two micropores (such as air stones or microporous aeration tubes) to generate bubbles at multiple locations in the liquid. However, these existing static porous aerators suffer from the following technical problems: Due to manufacturing processes, the size of each micropore is not entirely uniform, leading to significant differences in air outlet velocity. Furthermore, due to spatial limitations, the distance from each micropore to the air inlet is inconsistent; micropores closer to the inlet have higher air pressure, while those farther away have lower air pressure, resulting in substantial differences in air outlet velocity. To minimize these velocity differences, manufacturers must make the micropores very fine, which makes them prone to clogging. Summary of the Invention

[0004] The problem solved by this invention is to provide a swirling aeration device that enables spiral aeration of liquids, reduces the resistance of the liquid in the aeration device, and effectively improves the stability and aeration rate of the aeration device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A swirling aeration device includes a cutting mechanism for cutting bubbles, an air injection mechanism for spiral aeration of the liquid at the liquid inlet end of the cutting mechanism, and a positioning mechanism for fixing the liquid at the liquid outlet end of the cutting mechanism.

[0007] The slitting mechanism includes a slitting cylinder, in which a plurality of slitting rings are installed at intervals. The radial outer side of the slitting rings is detachably connected to the interior of the slitting cylinder. The radial inner side of the slitting rings is provided with a plurality of slitting rods extending toward the center of the slitting rings. The outer end of the slitting rods is provided with a slitting head. A swirling groove is formed between adjacent slitting rings and the inner wall of the slitting cylinder.

[0008] The beneficial effects of this invention are:

[0009] Liquid flows into the aeration device, and the air injection mechanism injects air into the liquid. Simultaneously, due to the spiral injection of air into the liquid, the gas drives the liquid to spiral forward in the cutting cylinder. The operator sets the number of cutting rings and cutting rods on the cutting rings according to the actual situation, thereby achieving the cutting of air bubbles within the liquid. Some liquid fills the vortex tank, increasing the rotating liquid area and the contact time between the gas-filled liquid and the cutting rods. This ensures that the air bubbles in the liquid are fully cut by the cutting rods and cutting head, preventing the high-speed liquid from releasing the incorporated gas. This achieves spiral aeration of the liquid, reduces the resistance of the liquid in the aeration device, and effectively improves the stability and aeration rate of the aeration device.

[0010] As an improved technical solution, the rear end of the slitting cylinder is provided with a plurality of slitting grooves extending toward the front end of the slitting cylinder, the slitting grooves are arranged around the center of the slitting cylinder, and the outside of the slitting ring is provided with slitting sliders that cooperate with the slitting grooves.

[0011] As an improved technical solution, the slitting head is composed of two interlocking conical heads, and the slitting head, the slitting rod, and the slitting ring are integrally formed.

[0012] As an improved technical solution, the gas injection mechanism includes a gas injection sleeve fitted onto the liquid inlet end of the slitting cylinder. The front part of the gas injection sleeve is provided with a gas injection hood. An air inlet support rod is installed at the air inlet end of the air injection hood. A connecting pipe is provided in the middle of the air inlet support rod. A positioning rod is connected to the rear end of the connecting pipe. An air inlet chamber communicating with the outer end is provided at the front end of the connecting pipe. An air outlet branch pipe communicating with the air inlet chamber is provided on the connecting pipe. The air outlet end of the air outlet branch pipe is fitted and installed in conjunction with the inner wall of the gas injection hood.

[0013] As an improved technical solution, the air injection hood includes a fixed section and an air intake section. The fixed section is arranged in a ring shape, and a positioning groove extending inward and opening downward is opened on the end face of the fixed section. The positioning groove is configured to cooperate with both ends of the air intake support rod. A fixing through hole is opened on the upper end face of the positioning groove, and a fixing wedge block that is snapped onto the end of the air intake support rod is inserted through the fixing through hole. The outer diameter of the air intake section decreases sequentially from front to back.

[0014] As an improved technical solution, the side wall of the connecting pipe is provided with an air outlet that communicates with the air inlet chamber, the end of the air outlet branch pipe is located at the air outlet, and the rear end of the connecting pipe is provided with a connection port.

[0015] As an improved technical solution, the outlet branch pipe is symmetrical about the center point of the connecting pipe, the outlet branch pipe extends from the inside to the outside and bends backward, and the outlet end of the outlet branch pipe has an oblique outlet that is parallel to the arc of the inner wall of the inlet section.

[0016] As an improved technical solution, a limiting block is provided on the side wall of the air outlet branch pipe at the obliquely cut air outlet, which is closely attached to the inner wall of the air inlet section.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Reference Figures 1-9 As shown, a swirl aeration device includes a cutting mechanism for cutting bubbles, an air injection mechanism for spiral aeration of the liquid at the liquid inlet end of the cutting mechanism, and a positioning mechanism for fixing the liquid at the liquid outlet end of the cutting mechanism.

[0032] The gas injection mechanism includes a gas injection sleeve 8 fitted onto the liquid inlet end of the cutting cylinder 1. The front of the gas injection sleeve 8 is provided with a gas injection hood, which includes a fixed section 14 and an air inlet section 15. The fixed section 14 is annularly arranged, and its end face has an inwardly extending and downwardly opening positioning groove 16. An air inlet support rod 9 is installed at the air inlet end of the gas injection hood. The positioning groove 16 is fitted to both ends of the air inlet support rod 9. A fixing through hole 17 is provided on the upper end face of the positioning groove 16. A fixing wedge block 18, which is fastened to the end of the air inlet support rod 9, passes through the fixing through hole 17. The outer diameter of the air inlet section 15 decreases sequentially from front to back. When the operator inserts the positioning groove 16 into both ends of the air inlet support rod 9, the fixing wedge block 18 is then inserted through the fixing through hole 17 into both ends of the air inlet support rod 9, thereby fixing the air inlet support rod 9. The air intake support rod 9 has a connecting pipe 10 in the middle. The front end of the connecting pipe 10 has an air intake chamber 12 that communicates with the outer end. The side wall of the connecting pipe 10 has an air outlet 20 that communicates with the air intake chamber 12. The connecting pipe 10 has an air outlet branch pipe 13 that communicates with the air intake chamber 12. The air outlet end of the air outlet branch pipe 13 is fitted into the inner wall of the air injection hood. The end of the air outlet branch pipe 13 is located at the air outlet 20. The rear end of the connecting pipe 10 has a connecting port 21. The air outlet branch pipe 13 is symmetrical with respect to the center point of the connecting pipe 10. The air outlet branch pipe 13 extends from the inside to the outside and bends backward. The air outlet end of the air outlet branch pipe 13 has a beveled air outlet 22 that is parallel to the arc of the inner wall of the air intake section 15. The side wall of the air outlet branch pipe 13 at the beveled air outlet 22 has a limiting block 23 that is close to the inner wall of the air intake section 15. The air injection mechanism not only aerates the injected liquid, but also drives the liquid to be spirally fed in through the spiral air delivery of the air outlet branch pipe 13. In order to ensure that the gas is spirally delivered, the shape of the air outlet branch pipe 13 is designed, and the obliquely cut air outlet 22 is set. The limiting block 23 is set to ensure that the obliquely cut air outlet 22 is tightly attached to the inner wall of the air inlet end. That is, the spiral air intake is carried out according to the shape of the air inlet section 15 to avoid the shape of the air inlet end affecting the air intake effect.

[0033] The slitting mechanism includes a slitting cylinder 1, inside which are installed a plurality of spaced-apart slitting rings 2. The radial outer surface of each slitting ring 2 is detachably connected to the interior of the slitting cylinder 1. The rear end of the slitting cylinder 1 has a plurality of slitting grooves 6 extending toward the front end, and these grooves 6 are arranged around the center of the slitting cylinder 1. The outer surface of each slitting ring 2 has slitting sliders 7 that cooperate with the grooves 6. The cooperation of the grooves 6 and sliders 7 allows for the detachable installation of the slitting rings 2 and the slitting cylinder 1, and the number of slitting rings 2 can be adjusted according to actual aeration needs. The radial inner surface of each slitting ring 2 has a plurality of slitting rods 3 extending toward the center of the slitting ring 2. The outer end of each rod 3 has a slitting head 4, which is formed by two interlocking conical heads. The slitting head 4, the rods 3, and the slitting rings 2 are integrally formed. The slitting head 4 can divert the passing liquid, that is, cut large bubbles in the liquid into smaller bubbles, thereby increasing the aeration rate of the liquid. A vortex groove 5 is formed between adjacent slitting rings 2 and on the inner wall of the slitting cylinder 1. The operator sets the number of slitting rings 2 and the number of slitting rods 3 on the slitting rings 2 according to the actual situation, thereby achieving the cutting of bubbles in the liquid. Some liquid will fill the vortex groove 5, increasing the rotating liquid area and increasing the contact time between the gas-filled liquid and the slitting rods 3, ensuring that the bubbles in the liquid are fully cut by the slitting rods 3 and the slitting head 4, preventing the high-speed liquid from releasing the incorporated gas.

[0034] The positioning mechanism includes a positioning sleeve 24 fitted onto the liquid outlet end of the cutting cylinder 1. The positioning sleeve 24 has several inwardly extending positioning brackets 25, and a positioning ring 26 is provided at the confluence of the positioning brackets 25. A positioning rod 11 is provided between the positioning ring 26 and the connection port 21. The front end of the positioning rod 11 is connected to the connection port 21 via a front connecting pipe 27, and the rear end of the positioning rod 11 is provided with a rear connecting pipe 28. The positioning rod 11 passes through the positioning ring 26. The positioning mechanism can fix the position of the aeration device. The positioning rod 11 passes through the cutting cylinder 1, stabilizing the position of the cutting cylinder 1 and preventing shaking during aeration and cutting, which would affect the stability of air injection. The front connecting pipe 27 fixes the front end of the positioning rod 11, the positioning ring 26 fixes the middle position of the positioning rod 11, preventing shaking of the positioning rod 11 inside the cutting cylinder 1, and the rear connecting pipe 28 connects the positioning rod 11 to other positions, preventing different fixing structures from affecting the fixation of the positioning rod 11.

[0035] In use, liquid flows into the aeration device, and the aeration mechanism injects gas into the liquid. Simultaneously, because the aeration mechanism injects gas into the liquid in a spiral motion, it not only aerates the injected liquid but also drives the liquid to spirally enter through the spiral air delivery via the outlet branch pipe 13. To ensure that the incoming gas is spirally delivered, the outlet branch pipe 13 is designed with a specific shape, and a slanted outlet 22 is provided. A limiting block 23 is provided to ensure that the slanted outlet 22 is tightly attached to the inner wall of the inlet end, i.e., spiral air intake is performed according to the shape of the inlet section 15, avoiding the shape of the inlet end affecting the air intake effect. When the gas is injected into the liquid, it drives the liquid to spirally advance in the cutting cylinder 1. The operator sets the number of cutting rings 2 and the number of cutting rods 3 on the cutting rings 2 according to the actual situation, thereby achieving the cutting of air bubbles in the liquid, partially eliminating the liquid... The filling of the swirl tank 5 increases the rotating liquid area and the contact time between the gas-filled liquid and the cutting rod 3, allowing the air bubbles in the liquid to be fully cut by the cutting rod 3 and the cutting head 4, preventing the high-speed liquid from releasing the gas it incorporates. The positioning rod 11 stabilizes the position of the cutting cylinder 1, preventing shaking during aeration and cutting, which would affect the stability of the aeration. The front connecting pipe 27 fixes the front end of the positioning rod 11, and the positioning ring 26 fixes the middle position of the positioning rod 11, preventing shaking of the positioning rod 11 inside the cutting cylinder 1. The rear connecting pipe 28 connects the positioning rod 11 to other positions, preventing the positioning rod 11 from being fixed due to different fixed connection structures. The above structure achieves spiral aeration of the liquid, reducing the resistance of the liquid in the aeration device, and effectively improving the stability and aeration rate of the aeration device. The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
