[0037] The present invention provides a mixing waterway system 1.

[0038] In one embodiment, if Figures 1 to 9As shown, the mixing waterway system 1 includes a microbubble ejector 100, a flow meter 200 and a static mixer 300. The microbubble ejector 100 includes a tube body 10 and a plugging component 20. The tube body 10 has a flow channel 11, and the two ends of the tube body 10 are respectively a liquid inlet end 12 and a liquid outlet end 13. One side of the tube body 10 is provided with an air inlet 14 connected to the flow channel 11. The plugging component 20 is accommodated in the tube body 10 and is used to plug the air inlet 14. When the liquid entering from the liquid inlet end 12 flows in the flow channel 11, negative pressure is generated and the plugging component 20 is driven to open the air inlet 14, so that external gas enters the flow channel 11 from the air inlet 14 and flows out from the liquid outlet end 13 with the liquid; the flow meter 200 is connected to the liquid inlet of the microbubble ejector 100. End 12, the flowmeter 200 is used to measure the flow rate of the liquid passing through the flowmeter 200; the static mixer 300 includes a sleeve 70 and a plurality of spiral modules 80, the sleeve 70 is connected to the liquid outlet end 13, the inner cavity 4721 of the sleeve 70 is connected to the flow channel 11, the plurality of spiral modules 80 are installed in the inner cavity 4721 of the sleeve 70 and are arranged in sequence along the extension direction of the sleeve 70, the axes of each spiral module 80 are the same and are coaxially arranged with the sleeve 70, each spiral module 80 includes a plurality of spiral blades 83 extending along the extension direction of the sleeve 70, each spiral blade 83 is arranged at circumferential intervals around the axis, and the side of the spiral blade 83 close to the inner wall of the sleeve 70 is a side edge 84, and the side edge 84 abuts against the inner wall of the sleeve 70.

[0039] When the mixing waterway system 1 of the present invention is in use, the mixing waterway system 1 is installed on the pipeline so that the liquid can flow through the flow meter 200, the microbubble ejector 100 and the static mixer 300 in sequence. When the liquid passes through the flow meter 200, the flow meter 200 measures the flow rate of the liquid and adjusts the gas supply to the microbubble ejector 100 according to the measured flow rate. It can be understood that under the same conditions, the larger the flow rate measured by the flow meter 200, the larger the gas supply to the microbubble ejector 100. After that, the gas and liquid are preliminarily mixed by the microbubble ejector 100 to form a gas-liquid mixture that flows out from the liquid outlet 13 to the static mixer 300. When the gas-liquid mixture flows into the static mixer 300, it will flow along the spiral blades 83 of each spiral module 80 and shake continuously, thereby fully mixing the gas and liquid.

[0040] The mixed waterway system 1 of the present invention measures the flow rate entering the microbubble ejector 100 by setting a flow meter 200, and can then adjust the gas supply according to the flow rate, thereby improving the mixing efficiency of the gas and liquid. In addition, by setting a static mixer 300, the gas-liquid mixture is continuously shaken, which increases the contact between the gas and the liquid, improves the gas solubility rate in the liquid, and has a better effect on the gas-liquid mixture. In addition, the side edge 84 of each spiral blade 83 abuts against the inner wall of the sleeve 70, which is conducive to the gas-liquid mixture to flow stably along the spiral blade 83, thereby improving the reliability of the use of the mixed waterway system 1.

[0041] Specifically, the flow meter 200 and the microbubble ejector 100 as well as the microbubble ejector 100 and the static mixer 300 may be directly connected or connected through a connecting pipe.

[0042] In one embodiment, if Figure 4 and Figure 5 As shown, a strip slit 15 is provided on the inner wall of the tube body 10 on the side away from the air inlet 14 at a position corresponding to the air inlet 14, and the extension direction of the strip slit 15 is inconsistent with the direction from the liquid inlet end 12 to the liquid outlet end 13, and the strip slit 15 is used to divide the gas entering the flow channel 11 from the air inlet 14 into microbubbles. It can be understood that when the gas enters the liquid, bubbles will be formed, and the bubbles will be cut into smaller microbubbles by the strip slit 15, which reduces the size of the bubbles, thereby increasing the gas solubility rate in the liquid, and the gas-liquid mixture has a better effect.

[0043] In one embodiment, if Figure 3 and Figure 4 As shown, the plugging assembly 20 includes a plugging member 21 and an elastic member 22. The plugging member 21 is used to plug the air inlet 14. One end of the elastic member 22 is connected to the pipe body 10, and the other end of the elastic member 22 is connected to the plugging member 21. The pipe body 10 is provided with a mounting tube 16. An activity space 161 that penetrates the mounting tube 16 is formed in the mounting tube 16. The air inlet 14 is formed on the side of the activity space 161 away from the flow channel 11. The plugging member 21 and the elastic member 22 are both located in the activity space 161. An air inlet cover 17 is detachably provided on the side of the mounting tube 16 where the air inlet 14 is located. The air inlet cover 17 has an air vent 171 that is connected to the air inlet 14. By providing a detachably connected mounting tube 16 and air inlet cover 17, the inspection and maintenance of the interior of the pipe body 10 are facilitated, and the convenience of use of the mixed waterway system 1 is improved.

[0044] In one embodiment, if Figure 5 As shown, the strip-shaped slit 15 is a groove 15a opened on the inner wall of the tube body 10, and the notch 151 of the groove 15a is arranged opposite to the gas inlet 14, and the extension direction of the groove 15a is perpendicular to the direction from the liquid inlet end 12 to the liquid outlet end 13, so as to realize the cutting of the bubbles formed by the gas, and the structural design is simple and reasonable. In addition, the extension direction of the groove 15a is perpendicular to the direction from the liquid inlet end 12 to the liquid outlet end 13, which is conducive to the cutting of the bubbles formed by the gas, thereby further improving the gas solubility rate in the liquid, and the effect of the ejected gas-liquid mixture is better.

[0045] In one embodiment, the groove walls 152 on both sides of the groove 15a are arranged in parallel along the direction from the liquid inlet end 12 to the liquid outlet end 13, and the spacing is less than or equal to 0.5 mm. It can be understood that the smaller the spacing between the groove walls 152 on both sides of the strip slit 15 from the liquid inlet end 12 to the liquid outlet end 13, the smaller the size of the cut microbubbles, and thus the higher the gas dissolution rate in the liquid, and the better the effect of the ejected gas-liquid mixture.

[0046] In one embodiment, if Figure 3 and Figure 4 As shown, an external threaded portion 432 is provided on the outer periphery of the mounting tube 16, and an internal threaded portion 432 for threadably cooperating with the external threaded portion 432 is provided inside the air intake cover 17, thereby realizing a detachable connection between the mounting tube 16 and the air intake cover 17, and making the structural design more reasonable.

[0047] In one embodiment, if Figure 4 As shown, a mounting step 162 is formed on one side of the mounting tube 16 where the air inlet 14 is located, and the microbubble ejector 100 also includes a flexible pad 30, which is arranged on the mounting step 162 and is used to press against the air inlet cover 17, and the flexible pad 30 has a through hole 31 connected to the air inlet 14, and the blocking member 21 is used to block the through hole 31. The provision of the flexible pad 30 improves the air tightness in the microbubble ejector 100, thereby further improving the reliability of the use of the mixing waterway system 1. In addition, by providing the mounting step 162, the installation of the flexible pad 30 is facilitated, the shaking of the flexible pad 30 is avoided, and the reliability of the use of the microbubble ejector 100 is further improved. Specifically, the flexible pad 30 can be a fluorine pad.

[0048] In one embodiment, an annular protrusion 18 is provided in the tube body 10, and the flow channel 11 is provided through the annular protrusion 18. An air outlet 181 is provided at a position of the annular protrusion 18 corresponding to the active space 161, which connects the active space 161 with the flow channel 11. The air outlet 181 is arranged opposite to the strip slit 15, and the size of the air outlet 181 along the direction from the liquid inlet end 12 to the liquid outlet end 13 is smaller than the size of the active space 161 along the direction from the liquid inlet end 12 to the liquid outlet end 13. It can be understood that the size of the air outlet 181 along the direction from the liquid inlet end 12 to the liquid outlet end 13 is smaller than the size of the active space 161 along the direction from the liquid inlet end 12 to the liquid outlet end 13, which can increase the flow rate of the gas, facilitate the bubbles formed by the gas to flow to the strip slit 15 and be cut into small microbubbles, and the air outlet 181 is arranged opposite to the strip slit 15, which is more conducive to the strip slit 15 cutting the bubbles formed by the gas, thereby improving the reliability of the mixed water channel system 1.

[0049] Furthermore, if Figure 4As shown, an annular buffer slope 182 is provided on the annular protrusion 18, and the annular buffer slope 182 is located on the side of the strip-shaped slit 15 facing the liquid inlet end 12, and the flow channel 11 corresponding to the annular buffer slope 182 is gradually set in the direction from the liquid inlet end 12 to the liquid outlet end 13. The annular buffer slope 182 is provided to buffer the liquid, so that the liquid can be fully mixed with the microbubbles, thereby improving the gas dissolution rate of the liquid.

[0050] In one embodiment, an annular guide slope 183 is provided on the annular protrusion 18, and the annular guide slope 183 is located on the side of the strip-shaped slit 15 facing the liquid outlet end 13, and the flow channel 11 corresponding to the annular guide slope 183 is gradually expanded in the direction from the liquid inlet end 12 to the liquid outlet end 13. The annular guide slope 183 is provided to facilitate the rapid release of the liquid mixed with the microbubbles, thereby improving the working efficiency of the mixing waterway system 1.

[0051] In one embodiment, the blocking member 21 is a spherical ball, the elastic member 22 is a spring 22a, and the blocking member 21 is partially embedded in the spring 22a, so that one end of the elastic member 22 is connected to the blocking member 21, and the structural design is more reasonable. Specifically, the blocking member 21 can be a tetrafluoroethylene ball 21a.

[0052] In one embodiment, if Figure 6 and Figure 7 As shown, the flow meter 200 includes a cylinder 40 and a magnetic induction component 50. The cylinder 40 has a flow path 41, and a mounting seat 42 is arranged on the outer periphery of the cylinder 40. A threaded sleeve 43 is arranged at one end of the cylinder 40. The threaded sleeve 43 is a metal part and includes a cylinder 431 and a threaded portion 432 arranged on the outer wall of the cylinder 431. The cylinder 431 and the threaded portion 432 are integrally formed by injection molding, and the cylinder 431 is sleeved on the outer periphery of the cylinder 40 and connected to the cylinder 40; the magnetic induction component 50 includes a turbine 51 and an induction mainboard 52. The induction mainboard 52 is installed in the mounting seat 42. The turbine 51 is arranged corresponding to the induction mainboard 52. The turbine 51 includes a rotating shaft 511 and a plurality of turbine blades 512 uniformly arranged along the circumferential direction of the rotating shaft 511. The rotating shaft 511 is rotatably installed in the flow path 41, and the plurality of turbine blades 512 are all spirally arranged along the axial direction of the rotating shaft 511.

[0053] When liquid flows through the flowmeter 200, because the turbine blades 512 are arranged in a spiral shape, the liquid will drive the turbine blades 512 to rotate, thereby causing the turbine 51 to continue to rotate. It can be understood that when the volume of the metering space is constant, that is, the size of the flow path 41 is constant, as long as the number of rotations of the turbine 51 is measured, the cumulative value of the volume of the fluid passing through the flowmeter 200 can be obtained. The number of rotations of the turbine 51 can be measured by the cooperation of the sensing mainboard 52 and the turbine blades 512, and then the cumulative value of the volume of the fluid passing through the flowmeter 200 can be obtained. It should be noted that the method of obtaining the cumulative value of the volume of the fluid passing through the flowmeter 200 by the number of rotations belongs to the prior art and will not be described in detail here. Specifically, the sensing mainboard 52 can be a Hall sensing mainboard 52, and the turbine blades 512 can be a rubidium magnet. The method of measuring the number of rotations of the turbine 51 by the cooperation of the Hall sensing mainboard 52 and the rubidium magnet belongs to the prior art and will not be described in detail here. By providing a threaded sleeve 43 made of metal, and the cylinder 431 and the threaded portion 432 of the threaded sleeve 43 are integrally formed by injection molding, the strength of the threaded sleeve 43 is greatly improved, and the damage to the threaded sleeve 43 caused by disassembly and assembly is reduced. Compared with the method of using plastic threads, the flow meter 200 of the present invention avoids the phenomenon of slipping and the failure of the threaded portion 432, can be repeatedly disassembled and assembled, ensures the normal connection with the pipeline, improves the reliability of the flow meter 200, extends its service life, and thus reduces the use cost of the mixing water system 1.

[0054] In one embodiment, an annular arch 44 is formed on the outer wall of the cylinder 40 and protrudes outward. A clamping block 441 is provided on the side wall of the annular arch 44 facing one end of the cylinder 40. A clamping hole 4311 is provided on the cylinder 431. The cylinder 431 abuts against the annular arch 44 and the clamping block 441 is engaged with the clamping hole 4311. The threaded sleeve 43 is radially limited by providing the clamping block 441 and the clamping hole 4311 to prevent the threaded sleeve 43 from rotating during installation, which is beneficial to the disassembly and assembly of the flow meter 200 and improves the convenience of use of the mixing water system 1.

[0055] Furthermore, a limiting ring 45 is formed at the end of the cylinder 40 where the cylinder 431 is located. The limiting ring 45 protrudes outward from the outer wall of the cylinder 40. The cylinder 431 is provided with an annular limiting groove 4312. The limiting ring 45 is used to extend into the annular limiting groove 4312, and the limiting ring 45 cooperates with the annular arch 44 to limit the cylinder 431. The limiting ring 45 and the annular arch 44 cooperate to achieve axial limitation of the threaded sleeve 43, prevent the threaded sleeve 43 from moving, and improve the reliability of the mixing water system 1.

[0056] In one embodiment, a first bracket 46 and a second bracket 47 are provided in the cylinder 40, and both the first bracket 46 and the second bracket 47 are provided with an avoidance hole 462 communicating with the flow path 41, a first rotation groove 461 is provided in the first bracket 46, and a second rotation groove 471 is provided in the second bracket 47, and both ends of the rotating shaft 511 are rotatably mounted on the first rotation groove 461 and the second rotation groove 471, respectively. By providing the first bracket 46 and the second bracket 47, the rotating shaft 511 is rotatably mounted in the flow path 41, and the structural design is more reasonable.

[0057] Furthermore, a ball 4611 is further provided in the first rotating groove 461, and the ball 4611 abuts against one end of the rotating shaft 511 rotatably mounted in the first rotating groove 461. The rotating shaft 511 will generate friction with the first rotating groove 461 when rotating, and the addition of the steel ball reduces the contact area between the rotating shaft 511 and the inner wall of the first rotating groove 461, thereby reducing the friction between the rotating shaft 511 and the first rotating groove 461, improving the rotation efficiency of the rotating shaft 511, and also improving the rotation stability of the rotating shaft 511.

[0058] In one embodiment, the first bracket 46 and the cylinder 40 are integrally formed, thereby improving the strength and service life of the first bracket 46 .

[0059] In one embodiment, the second bracket 47 includes a connecting ring 472 and a mounting frame 473 connected to the side of the connecting ring 472 facing the rotating shaft 511, the mounting frame 473 is provided with an avoidance hole 462 and a second rotating groove 471, the connecting ring 472 is used to be bonded to the inner wall of the cylinder 40, and the connecting ring 472 has an inner cavity 4721 connected to the flow path 41. By providing the connecting ring 472, the installation of the second bracket 47 is facilitated, and the use flexibility of the mixing water system 1 is improved.

[0060] In one embodiment, the mounting seat 42 forms a mounting cavity 421 with an opening 422 on one side, the sensing mainboard 52 is mounted in the mounting cavity 421, and the opening 422 is detachably covered with a mounting cover 60. The mounting cover 60 protects the sensing mainboard 52 disposed in the mounting seat 42, further improving the reliability of the hybrid water system 1.

[0061] In one embodiment, mounting ears 48 are provided on both sides of the cylinder 40 that are opposite to each other along the circumference thereof, the mounting seat 42 is located between the two mounting ears 48, and each mounting ear 48 is used to be detachably connected to an external structure. The installation of the flow meter 200 is facilitated by providing the mounting ears 48, and the use flexibility of the mixing waterway system 1 is improved.

[0062] It should be noted that the size of the sleeve 70 is a standard 6-point pipe size, and the length of the sleeve 70 can be adjusted according to actual needs. At the same time, the number of spiral modules 80 can also be increased or decreased according to the length of the sleeve 70.

[0063] In one embodiment, if Figure 8 and Fig. 9 As shown, the spiral blades 83 on the same spiral module 80 have the same rotation direction, the spiral blades 83 on any two adjacent spiral modules 80 have opposite rotation directions, and in any two adjacent spiral modules 80, the end of the spiral blade 83 on one spiral module 80 abuts against the end of the spiral blade 83 on the other spiral module 80 arranged adjacent thereto. The spiral blades 83 on any two adjacent spiral modules 80 have opposite rotation directions, so that the liquid and gas entering the inner cavity 4721 of the sleeve 70 are fully mixed during the deceleration, acceleration and turning process. At the same time, the polluted particles in the liquid are not easy to adhere to the surface of the spiral blades 83 during high-speed rotation and turning, thereby preventing the accumulation of pollutants and causing blockage; the inner cavity 4721 of the sleeve 70 is divided by multiple spiral blades 83, so that the liquid moves in multiple separate cavities and mixes with the gas, thereby increasing the contact area between the liquid and the spiral blades 83, thereby increasing the rotation angle and acceleration of the liquid, thereby making it easier for the liquid and gas to mix and improving the mixing efficiency. The ends of the spiral blades 83 on any two adjacent spiral modules 80 are abutted, and at the same time, the side edges 84 of each spiral blade 83 are abutted against the inner wall of the sleeve 70, so that the spiral blades 83 divide the inner cavity 4721 of the sleeve 70 into multiple mixing cavities, thereby improving the gas-liquid mixing efficiency and reducing the deposition of pollutants. The sleeve 70 will not be blocked, thereby extending its service life.

[0064] It can be understood that the spiral module 80 is made of CPVC. The material of the spiral module 80 is chlorinated polyvinyl chloride (CPVC). CPVC has excellent tensile strength, bending strength, bending modulus and pressure bearing capacity, and has good heat resistance and chemical corrosion resistance. By using CPVC to make the spiral module 80, its service life and compressive and bending strength can be improved to prevent it from being damaged.

[0065] In one embodiment, among any two adjacent spiral modules 80, one spiral module 80 is a first spiral module 81, and the other spiral module 80 is a second spiral module 82. The surface of the spiral blade 83 of the first spiral module 81 is a matte surface, and the surface of the spiral blade 83 of the second spiral module 82 is a mirror surface. The first spiral module 81 and the second spiral module 82 have opposite rotation directions and are arranged alternately. The surface of the spiral blade 83 of the first spiral module 81 is treated with a high-precision graining process to be a matte surface, which can decelerate and break up and cut into multiple microbubbles when the gas and liquid pass through quickly, thereby improving the mixing efficiency of the gas and liquid. The spiral blade 83 of the second spiral module 82 can accelerate the flow and rotation of the gas and liquid after being precisely mirrored, which can accelerate the flow of the gas-liquid mixture and better dissolve the gas into the liquid.

[0066] In one embodiment, the number of spiral blades 83 of the first spiral module 81 and the number of spiral blades 83 of the second spiral module 82 are the same, and the spiral angles of the spiral blades 83 on the first spiral module 81 are the same; the spiral angles of the spiral blades 83 on the second spiral module 82 are the same. The number of spiral blades 83 of the first spiral module 81 and the number of spiral blades 83 of the second spiral module 82 are the same, so that the spiral blades 83 of the adjacent first spiral module 81 and the second spiral module 82 can correspond one to one, and the inner cavity 4721 of the sleeve 70 is divided into a plurality of mixing cavities with the same number of spiral blades 83, so that the flow of liquid in each mixing cavity is smoother, the deposition of pollutants is prevented, and the service life thereof is increased.

[0067] Furthermore, the spiral blades 83 of each spiral module 80 are evenly distributed along the axial direction of the axis. The spiral blades 83 are evenly distributed, so that the spiral blades 83 can evenly divide the inner cavity 4721 of the sleeve 70 into a plurality of mixing cavities of the same size, thereby dividing the liquid into multiple portions, increasing the contact area between the liquid and the turbine blades 512, and improving the mixing efficiency of the liquid and the gas.

[0068] Furthermore, the number of spiral blades 83 on each spiral module 80 is three. When the number of spiral blades 83 is three, the inner cavity 4721 of the sleeve 70 is evenly divided into mixing cavities of the same size, at which time the water flow is maximized and the water resistance is minimized, thereby reducing the probability of pollutant deposition.

[0069] In one embodiment, the spiral blade 83 has a uniform thickness, which makes it more stable, and when it is impacted by liquid, the force is more uniform, and the turbine blade 512 is not easily deformed, thereby extending the service life.

[0070] In one embodiment, the two side edges 84 of the spiral blade 83 along the extension direction of the sleeve 70 are respectively the first edge 85 and the second edge 86. The connection between the first edge 85 and the side edge 84 and the connection between the second edge 86 and the side edge 84 form a corner 87. In any two adjacent spiral modules 80, the corner 87 on one spiral module 80 abuts against the corner 87 on the other spiral module 80 arranged close thereto. The adjacent corners 87 abut, that is, the bottom of the previous spiral blade 83 is connected to the top of the next spiral blade 83, so that the fluid channel composed of the turbine blades 512 arranged alternately with opposite rotation directions is continuous and smooth.

[0071] In one embodiment, in each spiral module 80, the first edges 85 of the plurality of spiral blades 83 are arranged flush, and the second edges 86 of the plurality of spiral blades 83 are arranged flush. The first edge 85 and the second edge 86 are arranged flush, so that the first edge 85 and the second edge 86 are more tightly combined when they abut, and no gap is generated between adjacent first spiral modules 81 and second spiral modules 82.

[0072] In one embodiment, the inner wall of the sleeve 70 is provided with a limiting groove at the position corresponding to each spiral blade 83, and the limiting groove and the side edge 84 of the corresponding spiral blade 83 are matched in shape and plugged in. The limiting groove is divided into a clockwise spiral limiting groove and a counterclockwise spiral limiting groove, which facilitates the assembly of the first spiral module 81 and the second spiral module 82 and improves the assembly efficiency.

[0073] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
