[0002] Protein skimmers work by utilizing the principle that air bubbles in water can adsorb various particulate matter and soluble organic matter mixed in the water. Aeration equipment or vortex pumps generate a large number of bubbles, which are then passed through the protein skimmer to purify the seawater. These bubbles concentrate on the water surface to form foam, which is then collected in a container on the surface, turning into a turbid liquid that is discharged. Traditional protein skimmers suffer from low air-water mixing efficiency and poor uniformity, and their water distribution effect cannot meet the requirements of high-performance protein skimmers.

[0016] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0017] This invention provides a protein separator, which is particularly suitable for use in industrialized aquaculture.

[0018] Please refer to Figures 1 to 15 As shown, a protein separator of the present invention includes: Protein separator tank 1; The Venturi tube 2 has an inlet 21 and an outlet 22 at both ends. The inner cavity of the Venturi tube 2 is provided with an annular ejector 23. The annular ejector 23 has an annular channel 231 inside. The top surface of the annular ejector 23 has two or more jet holes 232 along the circumferential direction. Water inlet pipe 3 is connected to inlet 21; The intake pipe 4 passes through the side wall of the venturi tube 2 and is connected to the annular ejector 23; Water distribution plate 5 has a conical surface 51; Water distribution fins 6, two or more water distribution fins 6 are arranged at intervals along the circumferential direction of the conical surface 51. The water distribution fins 6 are integrally formed with strip section 61 and spiral section 62. Strip section 61 is perpendicular to water distribution plate 5. Strip section 61 is connected to the inner wall of protein separator barrel 1. Spiral section 62 is connected to conical surface 51. The drain pipe 7 is connected to the outlet 22 at one end and passes through the protein separator barrel 1 at the other end and extends between the strip sections 61 of two or more water distribution fins 6.

[0019] As can be seen from the above description, the beneficial effects of the present invention are as follows: A protein separator, in which an annular ejector 23 is added inside the Venturi tube 2 body, gas enters the annular channel 231 of the annular ejector 23 from the inlet pipe 4, and is ejected from multiple jet holes 232 arranged at intervals in the circumferential direction, thereby uniformly mixing with the water flow entering from the inlet 21. After the gas and water are mixed, they are discharged from the outlet 22 of the Venturi tube 2, and then sent into the interior of the protein separator barrel 1 through the drain pipe 7. After the water flow enters between the strip sections 61 of two or more water distribution fins 6, it flows uniformly along the strip sections 61, generates vortices when passing through the spiral section 62, and finally is uniformly dispersed through the conical surface 51 of the water distribution plate 5, completing the uniform water distribution. The protein separator provided by the present invention optimizes the gas-water mixing structure of the Venturi mixer, improves the gas-water mixing efficiency and uniformity, and improves the water distribution uniformity of the water distributor, which is conducive to improving the working performance of the equipment and can meet the usage requirements of high-performance protein separator equipment.

[0020] Furthermore, the inner cavity of the venturi tube 2 is provided with a tapered contraction tube 24, and the annular ejector 23 is arranged around the tapered contraction tube 24.

[0021] As can be seen from the above description, the conical contraction tube 24 is conical in shape, and its function is to increase the water flow velocity. The annular ejector 23 is arranged around the conical contraction tube 24, thereby improving the water-air mixing effect.

[0022] Furthermore, the Venturi tube 2 includes a diffuser 25, an inlet union 26, an outlet union 27, and an air inlet union 28. The annular ejector 23 and the conical contraction tube 24 are both disposed inside the diffuser 25. The inlet 21 is disposed on the inlet union 26. One end of the diffuser 25 is connected to the inlet pipe 3 through the inlet union 26. The outlet 22 is disposed on the outlet union 27. The other end of the diffuser 25 is connected to the drain pipe 7 through the outlet union 27. The annular ejector 23 is connected to the air inlet pipe 4 through the air inlet union 28.

[0023] As can be seen from the above description, the diffuser 25 connects the inlet pipe 3 and the outlet pipe 7 through the inlet fitting 26 and the outlet fitting 27. After the water flows into the diffuser 25, it is mixed with water and air through the conical contraction pipe 24 and the annular ejector 23 before being transported into the protein separator tank 1.

[0024] Furthermore, the inner wall of the spiral segment 62 is provided with a spiral boss 621.

[0025] As can be seen from the above description, the function of the spiral boss 621 is to further improve the water distribution effect.

[0026] Furthermore, the spiral boss 621 has the same spiral direction as the spiral segment 62.

[0027] As can be seen from the above description, the spiral boss 621 is designed to rotate in the same direction as the spiral segment 62, which can improve the water distribution effect without hindering the water flow and reducing the flow rate.

[0028] Furthermore, it also includes a collection cup 8 and a foam crawler tube 9. The foam crawler tube 9 covers the top opening of the protein separator barrel 1, and the collection cup 8 covers the foam crawler tube 9. The collection cup 8 is detachably connected to the protein separator barrel 1.

[0029] As can be seen from the above description, the collection cup 8 and the protein separator tank 1 are detachably connected, which facilitates disassembly and cleaning.

[0030] Furthermore, the collection cup 8 is provided with a rotating cleaning assembly 81, which includes a first cleaning component 811 for cleaning the inner wall of the collection cup 8 and a second cleaning component 812 for cleaning the side wall of the foam climbing tube 9.

[0031] As can be seen from the above description, by designing a rotating cleaning component 81 inside the collection cup 8, the self-cleaning function of the collection cup 8 can be achieved. It can simultaneously clean the inner wall of the collection cup 8 and the side wall of the foam climbing tube 9, resulting in high cleaning efficiency and improving the working performance of the protein separator.

[0032] Furthermore, the collection cup 8 is provided with a fixed toothed disc 82, which is coaxially provided with an annular internal tooth 821 and an annular external tooth 822. The rotating cleaning assembly 81 also includes a main shaft 813 and a transmission arm 814. One end of the main shaft 813 is rotatably connected to the top cover of the collection cup 8, and the other end of the main shaft 813 is connected to the transmission arm 814. The first cleaning component 811 and the second cleaning component 812 are both rotatably mounted on the transmission arm 814. The first cleaning component 811 meshes with the annular external tooth 822, and the second cleaning component 812 meshes with the annular internal tooth 821.

[0033] As can be seen from the above description, when the main shaft 813 rotates, it drives the transmission arm 814 to rotate. Under the action of the annular external gear 822, the first cleaning component 811 not only rotates circumferentially with the transmission arm 814, but also rotates on its own axis. The second cleaning component 812 does the same. Thus, the inner wall of the collection cup 8 and the side wall of the foam climbing tube 9 are cleaned at the same time, and the wall panel will not be left with cleaning line marks due to uneven cleaning.

[0034] Furthermore, the collection cup 8 is provided with a snap-fit ​​bolt 83, and the protein separator barrel 1 is provided with a snap-fit ​​slot 11 that engages with the snap-fit ​​bolt 83.

[0035] As can be seen from the above description, the protein separator collection cup 8 has a detachable structure. The collection cup 8 is designed with a snap-fit ​​bolt 83, and the protein separator barrel 1 is designed with a snap-fit ​​slot 11. During installation, simply align the snap-fit ​​bolt 83 with the snap-fit ​​slot 11, insert it, and tighten it to complete the connection between the collection cup 8 and the protein separator barrel 1. It has the advantage of convenient disassembly and assembly, which is conducive to the cleaning of the collection cup 8 and the maintenance of the components.

[0036] Furthermore, the protein separator barrel 1 is provided with a screw-on boss 12, and the collection cup 8 is provided with a positioning groove 84. The inner wall of the positioning groove 84 is provided with a slot 85 for the screw-on boss 12 to be inserted.

[0037] As can be seen from the above description, when using the screw-on assembly structure, after assembling the screw-on boss 12 of the protein separator barrel 1 with the positioning groove 84 of the collection cup 8, rotating the collection cup 8 causes the screw-on boss 12 to snap into the slot 85, thus completing the fixed assembly of the collection cup 8 and the protein separator barrel 1.

[0038] Please refer to Figures 1 to 15 As shown, Embodiment 1 of the present invention is: a protein separator, comprising: Protein separator tank 1; The Venturi tube 2 has an inlet 21 and an outlet 22 at both ends. The inner cavity of the Venturi tube 2 is provided with an annular ejector 23. The annular ejector 23 has an annular channel 231 inside. The top surface of the annular ejector 23 has two or more air jet holes 232 along the circumferential direction. The two or more air jet holes 232 are evenly distributed at intervals along the circumferential direction on the top surface of the annular ejector 23. The air jet holes 232 are strip-shaped holes. Water inlet pipe 3 is connected to inlet 21; The intake pipe 4 passes through the side wall of the venturi tube 2 and is connected to the annular ejector 23; The water distribution plate 5 has a conical surface 51 with a cone angle ranging from 120° to 150°. The cone angle of the water distribution plate 5 can be flexibly adjusted according to the specifications of the protein separator, thereby controlling the water flow rate. Water distribution fins 6, two or more water distribution fins 6 are arranged at intervals along the circumference of the conical surface 51. The water distribution fins 6 are integrally formed with strip section 61 and spiral section 62. Strip section 61 is perpendicular to water distribution plate 5 and connected to the inner wall of protein separator barrel 1. Spiral section 62 is welded to conical surface 51. The spiral angle of spiral section 62 relative to the plane perpendicular to strip section 61 is greater than 60°. The spiral angle can be flexibly adjusted according to the specifications of protein separator, thereby adjusting the water distribution effect. The drain pipe 7 is connected to the outlet 22 at one end and passes through the protein separator barrel 1 at the other end and extends between the strip sections 61 of two or more water distribution fins 6.

[0039] The venturi tube 2 has a tapered contraction tube 24 inside, and an annular ejector 23 is arranged around the tapered contraction tube 24. The venturi tube 2 includes a diffuser 25, a water inlet connector 26, a water outlet connector 27, and an air inlet connector 28. The annular ejector 23 and the tapered contraction tube 24 are both located inside the diffuser 25. The inlet 21 is located on the water inlet connector 26. One end of the diffuser 25 is connected to the water inlet pipe 3 through the water inlet connector 26, and the outlet 22 is located on the water outlet connector 27. The other end of the diffuser 25 is connected to the drain pipe 7 through the water outlet connector 27. The annular ejector 23 is connected to the air inlet pipe 4 through the air inlet connector 28. The inner wall of the spiral section 62 has a spiral boss 621. Preferably, the helix angle of the spiral boss 621 relative to the plane perpendicular to the strip section 61 is smaller than the helix angle of the spiral section 62 relative to the plane perpendicular to the strip section 61. The spiral boss 621 has a spiral angle ranging from 30° to 60° relative to the plane perpendicular to the strip segment 61. The spiral boss 621 adopts a semi-circular cross-section design, which improves water distribution without obstructing water flow and reducing flow velocity. The spiral direction of the spiral boss 621 is the same as that of the spiral segment 62. The spiral boss 621 is designed to rotate in the same direction as the spiral segment 62, thus improving water distribution without obstructing water flow and reducing flow velocity. It also includes a collection cup 8 and a foam crawler tube 9. The foam crawler tube 9 covers the top opening of the protein separator barrel 1, and the collection cup 8 covers the foam crawler tube 9. The collection cup 8 is detachably connected to the protein separator barrel 1. The collection cup 8 contains a rotating cleaning assembly 81, which includes a first cleaning component 811 for cleaning the inner wall of the collection cup 8 and a second cleaning component 812 for cleaning the side wall of the foam crawler tube 9. The collection cup 8 is equipped with a fixed gear disc 82, which has annular internal teeth 821 and annular external teeth 822. The rotating cleaning assembly 81 also includes a main shaft 813 and a transmission arm 814. The main shaft 813, annular internal teeth 821, and annular external teeth 822 are coaxially arranged. One end of the main shaft 813 is rotatably connected to the top cover of the collection cup 8, and the other end of the main shaft 813 is connected to the transmission arm 814. The first cleaning component 811 and the second cleaning component 812 are both rotatably mounted on the transmission arm 814. The first cleaning component 811 meshes with the annular external teeth 822, and the second cleaning component 812 meshes with the annular internal teeth 821. The collection cup 8 is equipped with a snap-fit ​​bolt 83, and the protein separator barrel 1 is equipped with a snap-fit ​​slot 11 that engages with the snap-fit ​​bolt 83.

[0040] Traditional venturi jet mixers used in aquaculture often suffer from drawbacks in practical applications. These limitations stem from the presence of impurities and viscosity in the aquaculture water, coupled with the relatively small size of the constriction tube and air inlet of the traditional venturi mixer, preventing the achievement of ideal flow rates and limiting the maximum air intake. The high-efficiency venturi mixer used in this embodiment separates the constriction tube and air inlet, with a larger constriction tube allowing for better passage of impurities and viscous liquids, resulting in lower tube resistance. The annular ejector 23 provides a larger air intake, enabling the protein skimmer to produce more bubbles. The ejector outlet 22 flows in the same direction as the water flow. If pressurized liquid oxygen is introduced at the air inlet, it further enhances the flow propulsion and mixing effects.

[0041] On the other hand, this embodiment optimizes and improves the problem of stain residue and cleaning of the existing protein separator collection cup 8 device. When the main shaft 813 rotates, it drives the transmission arm 814 to rotate on the radial surface inside the collection cup 8, and at the same time drives the first cleaning component 811 and the second cleaning component 812 set thereon to rotate. The first cleaning component 811 and the second cleaning component 812 will rotate on their own axis while rotating in the circumferential direction under the meshing of the annular internal teeth 821 and the annular external teeth 822, respectively, thereby cleaning the inner wall of the outer collection cup 8 and the inner and outer walls of the middle foam climbing tube 9.

[0042] Please refer to Figures 8 to 9 As shown, Embodiment 2 of the present invention is based on Embodiment 1: the collecting cup 8 is provided with an annular mounting part, and the snap-fit ​​bolts 83 are disposed on the annular mounting part. The protein separator barrel 1 is provided with an annular support part for supporting the annular mounting part, and the snap-fit ​​slots 11 are disposed on the annular support part. The annular support part is used to support the annular mounting part, ensuring the stability of the collecting cup 8 during installation. Two or more snap-fit ​​bolts 83 are spaced apart along the circumferential direction on the annular mounting part, and two or more snap-fit ​​slots 11 are spaced apart along the circumferential direction on the annular support part. By using multiple sets of snap-fit ​​bolts 83 and multiple sets of snap-fit ​​slots 11 for fixing, the stability of the collecting cup 8 during installation is improved. The snap bolt 83 includes a connecting post 831 and a clamping post 832. The connecting post 831 is disposed on the annular mounting part, and the clamping post 832 is disposed on the connecting post 831. The diameter of the connecting post 831 is smaller than the diameter of the clamping post 832. The snap groove 11 includes a communicating slot 111 and a limiting groove 112. The diameter of the slot 111 is larger than the clamping post 832, and the diameter of the limiting groove 112 is larger than the connecting post 831 and smaller than the clamping post 832.

[0043] Please refer to Figures 10 to 11As shown, the difference between Embodiment 3 and Embodiment 1 of the present invention is as follows: the protein separator barrel 1 is provided with a screw-on protrusion 12, and the collection cup 8 is provided with a positioning groove 84. The inner wall of the positioning groove 84 is provided with a slot 85 for inserting the screw-on protrusion 12.

Multiple sets of screw-on protrusions 12 and multiple sets of slots 85 are used for fixing, improving the stability of the collection cup 8 installation. The number of screw-on protrusions 12 is odd. The shape of the screw-on protrusion 12 is fan-shaped. The surface of the screw-on protrusion 12 is provided with a rubber layer. The rubber layer serves to absorb shock and prevent the screw-on protrusion 12 from loosening after engaging with the slot 85.

[0044] Please refer to Figures 12 to 13 As shown, in Embodiment 4 of the present invention, based on Embodiment 1, both the first cleaning component 811 and the second cleaning component 812 are brush rollers. The surface of the brush roller is provided with spiral bristles 8111. Compared with ordinary single-row bristles or scrapers, the rotating spiral bristles clean more thoroughly and evenly, and will not leave cleaning lines on the wall panel due to uneven cleaning.

[0045] Please refer to Figures 14 to 15 As shown, the difference between Embodiment 5 and Embodiment 4 of the present invention is that the surface of the brush roller is provided with a silicone scraper 8112. The silicone scraper 8112 has a certain elastic deformation capability, which can ensure that the cleaning surface is always in close contact with the wall to be cleaned, thus ensuring the cleaning effect.

[0046] Please refer to Figures 12 to 15 As shown, Embodiment Six of the present invention is based on Embodiment One: a spray assembly 86 is provided on the main shaft 813, and a spray medium channel communicating with the spray assembly 86 is provided inside the main shaft 813.

The housing 861 is mounted on the main shaft 813, and the inclined spray head 862 and the omnidirectional spray head 863 are mounted on the housing 861. The inclined spray head 862 and the omnidirectional spray head 863 are connected to the spray medium channel through the housing 861. The inclined spray head 862 faces the inner circumferential wall of the collection cup 8 and the outer wall of the foam climbing tube 9, and the omnidirectional spray head 863 is used to clean the inner wall of the foam climbing tube 9. An electric actuator 87 is provided on the top cover, and the electric actuator 87 is connected to the main shaft 813.

[0047] In summary, the protein separator of this invention adds an annular ejector inside the Venturi tube body. Gas enters the annular channel of the ejector through the inlet pipe and is ejected from multiple jet holes spaced apart in the circumferential direction, thus uniformly mixing with the water flowing in from the inlet. The mixed gas and water are discharged from the outlet of the Venturi tube and then sent into the protein separator barrel through the drain pipe. The water flows between the strip sections of two or more water distribution fins and flows uniformly along the strip sections. A vortex is generated when it passes through the spiral section, and finally, it is evenly dispersed through the conical surface of the water distribution plate, completing uniform water distribution. The protein separator provided by this invention optimizes the gas-water mixing structure of the Venturi mixer, improves the gas-water mixing efficiency and uniformity, and also improves the water distribution uniformity of the water distributor, which is beneficial to improving the working performance of the equipment and can meet the requirements of high-performance protein separator equipment.

[0048] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention.
