Description

Technical Field

[0001] This application relates to the field of recirculating aquaculture technology, and in particular to a protein separator. Background Technology

[0002] As a core component of recirculating aquaculture systems, protein skimmers remove organic pollutants such as proteins and colloids from water through physicochemical processes, maintaining water quality stability. According to the "Technical Guidelines for Aquaculture Engineering," fish mortality rates increase by more than 20% when protein levels in aquaculture water exceed 5 mg / L. Currently, in high-density intensive aquaculture models, traditional protein skimmers face the common industry problem of insufficient high-load processing efficiency. Utility Model Content

[0003] Therefore, it is necessary to provide a protein separator that can better separate organic matter from wastewater.

[0004] A protein separator, comprising:

[0005] The reaction chamber is provided with an inlet pipe and an outlet pipe at its top and bottom, respectively, and a foam outlet is also provided at the top of the reaction chamber.

[0006] The pump body, with both its inlet and outlet ends connected to the bottom of the reaction chamber;

[0007] An air supply assembly is connected to the pump body; the air supply assembly is used to supply air to the water being pumped by the pump body, so that the gas dissolves in the water being pumped by the pump body to form dissolved air water; and

[0008] A microbubble generating component is disposed within the reaction chamber and near the water outlet of the pump body; the microbubble generating component includes a first porous plate, a second porous plate, and a cutting blade, wherein the first porous plate and the second porous plate are arranged alternately from bottom to top along the height direction of the reaction chamber; the cutting blade is rotatably disposed between the first porous plate and the second porous plate, and both ends of the cutting blade are rotatably connected to the first porous plate and the second porous plate, respectively.

[0009] In one embodiment, the first porous plate is provided with a plurality of dividing holes for air bubbles to pass through, and the second porous plate is provided with a plurality of dividing holes for air bubbles to pass through.

[0010] In one embodiment, both ends of the cutting blade are provided with connecting shafts, and the connecting shafts at both ends of the cutting blade are rotatably connected to the first perforated plate and the second perforated plate, respectively.

[0011] In one embodiment, the protein separator further includes a release tank disposed within the reaction chamber. The outlet end of the pump body extends into the reaction chamber and is connected to the bottom end of the release tank. The top end of the release tank has a first opening. A first porous plate is disposed at the first opening of the release tank. The second porous plate and the cutting blade are both disposed outside the release tank.

[0012] In one embodiment, the first perforated plate, the second perforated plate, and the cutting blade are coaxially arranged, the outer diameter of the second perforated plate is larger than the outer diameter of the first perforated plate, the outer diameter of the first perforated plate matches the size of the opening of the first opening of the release tank, and the outer diameter of the second perforated plate matches the size of the inner diameter of the reaction chamber.

[0013] In one embodiment, the outer edge of the second porous plate is further provided with fixing holes for detachably and securely connecting the second porous plate and the reaction chamber.

[0014] In one embodiment, the fixing hole is an arc-shaped hole, and there are multiple arc-shaped holes, which are distributed at intervals along the circumference of the second porous plate on the outer edge of the second porous plate.

[0015] In one embodiment, the gas supply assembly includes a venturi tube, the air inlet of which is exposed to the outside, the water inlet of which is connected to the pump body, and the air outlet of which is connected to the reaction chamber.

[0016] In one embodiment, the protein separator further includes a water distribution element disposed within the reaction chamber and connected to the inlet pipe.

[0017] In one embodiment, the protein separator further includes at least one of an exhaust pipe and a transparent observation tube, the exhaust pipe being connected to the liquid outlet pipe and the transparent observation tube being connected to the side wall of the reaction chamber.

[0018] In the aforementioned protein separator, both the inlet and outlet of the pump body are connected to the reaction chamber, allowing wastewater in the reaction chamber to be drawn into the pump body. During the pumping process, the air supply component supplies air to the water being pumped, causing the gas to dissolve in the water to form dissolved air water. The bubbles released by the dissolved air water enter the reaction chamber through the bottom and flow upward within the chamber. Simultaneously, the wastewater to be treated enters the reaction chamber through the liquid inlet pipe at the top and flows downward within the chamber. During the contact between the wastewater and the bubbles, the organic matter containing protein in the wastewater forms foam. This foam is eventually discharged through the foam outlet at the top of the reaction chamber, while the separated water (i.e., clear liquid) is discharged to the outside through the liquid outlet pipe at the bottom of the reaction chamber, thus completing the separation of organic matter from water in the wastewater.

[0019] In this design, since the outlet of the pump body is located near the microbubble generating component, the water carrying bubbles sprayed from the outlet of the pump body can act on the microbubble generating component. During the rise of the bubbles, the bubbles pass through the three-stage cutting of the first porous plate, the cutting blade, and the second porous plate of the microbubble generating component, so that the released small bubbles can be divided into smaller and denser microbubbles. As the microbubbles rise, they become larger and have greater tension, which can increase their residence time in the water. This results in better contact with organic matter such as proteins in the wastewater, making it easier to separate the water from the organic matter such as proteins. Furthermore, the microbubbles are not prone to rupture, preventing the attached or separated organic matter from returning to the water, thus effectively improving the separation effect of the protein separator.

[0027] like Figure 1 and Figure 2As shown, this application provides a protein separator 400, which includes a reaction chamber 410, a pump body 420, an air supply assembly 430, and a microbubble generating assembly 440. The reaction chamber 410 has an inlet pipe 411 and an outlet pipe 412 at its top and bottom, respectively. The top of the reaction chamber 410 also has a foam outlet 413 located axially above the reaction chamber 410. The pump body 420 has both its inlet and outlet connected to the bottom of the reaction chamber 410. The air supply assembly 430 is connected to the pump body 420 and is used to supply air to the water being pumped to the pump body 420. The gas dissolves in the water transported by the pump body 420 to form dissolved gas water. The microbubble generating component 440 is disposed in the reaction chamber 410 and is located near the water outlet of the pump body 420. The microbubble generating component 440 includes a first porous plate 441, a second porous plate 443 and a cutting blade 442. The first porous plate 441 and the second porous plate 443 are arranged alternately from bottom to top along the height direction of the reaction chamber 410. The cutting blade 442 is rotatably disposed between the first porous plate 441 and the second porous plate 443, and both ends of the cutting blade 442 are rotatably connected to the first porous plate 441 and the second porous plate 443 respectively.

[0028] The aforementioned protein separator 400, the inlet and outlet of the pump body 420 are simultaneously connected to the reaction chamber 410, so that the sewage in the reaction chamber 410 can be drawn into the pump body 420. During the pumping process, the air supply component 430 can supply air to the water conveyed by the pump body 420 so that the gas dissolves in the water conveyed by the pump body 420 to form dissolved air water. The air bubbles released by the dissolved air water enter the reaction chamber 410 through the bottom end and flow from bottom to top in the reaction chamber 410. Meanwhile, the wastewater to be treated enters the reaction chamber 410 through the inlet pipe 411 at the top of the reaction chamber 410 and flows from top to bottom inside the reaction chamber 410. During the process of contact between the wastewater and the bubbles, the organic matter containing protein in the wastewater will form foam. The foam will eventually be discharged through the foam outlet 413 at the top of the reaction chamber 410. The water separated from the wastewater (i.e., clear liquid) is discharged to the outside through the outlet pipe 412 at the bottom of the reaction chamber 410, thereby completing the separation of organic matter and water in the wastewater.

[0029] In this scheme, since the outlet end of the pump body 420 is located near the microbubble generating component 440, the water carrying bubbles sprayed from the outlet end of the pump body 420 can act on the microbubble generating component 440. During the rise of the bubbles, the bubbles pass through the three-stage cutting of the first porous plate 441, the cutting blade 442 and the second porous plate 443 of the microbubble generating component 440 in sequence, so that the released small bubbles can be divided into smaller and denser microbubbles. As the microbubbles rise, they become larger and have greater tension, which can increase their residence time in the water. This results in better contact with organic matter such as proteins in the sewage, making it easier to separate the water from the organic matter such as proteins. Furthermore, the microbubbles are not easy to break, preventing the attached or separated organic matter from returning to the water, effectively improving the separation effect of the protein separator 400.

[0030] like Figure 3 As shown, specifically, the first porous plate 441 is provided with a plurality of dividing holes 444 for bubbles to pass through. During the process of the bubbles passing through the dividing holes 444 on the first porous plate 441, the hole walls of the dividing holes 444 on the first porous plate 441 play a dividing role on the bubbles, so that the bubbles can be divided into a plurality of smaller bubbles.

[0031] After passing through the first porous plate 441, the bubble continues to rise and approach the cutting blade 442. Since the cutting blade 442 can rotate under the action of the airflow, the rotating cutting blade 442 can further divide this part of the bubble, so that the bubble can be divided into multiple small bubbles again.

[0032] The second porous plate 443 is provided with multiple dividing holes 444 for bubbles to pass through. After the bubbles pass through the cutting blades 442, they continue to rise and approach the second porous plate 443. During the process of the bubbles passing through the dividing holes 444 on the second porous plate 443, the hole walls of the dividing holes 444 on the second porous plate 443 again divide the bubbles, so that the bubbles can be divided into multiple small bubbles again. This makes the small bubbles rising to the top of the reaction chamber 410 smaller and denser, which is beneficial to improving the separation effect of the protein separator 400.

[0033] like Figure 2 As shown, in one embodiment, the protein separator 400 further includes a release tank 450, which is disposed inside the reaction chamber 410. The outlet end of the pump body 420 extends into the reaction chamber 410 and is connected to the bottom end of the release tank 450. The top end of the release tank 450 has a first opening 452. A first porous plate 441 is disposed at the first opening 452 of the release tank 450. A second porous plate 443 and a cutting blade 442 are both disposed outside the release tank 450.

[0034] Specifically, the dissolved air water sprayed from the outlet end of the pump body 420 enters the release tank 450. The bubbles released by the dissolved air water flow from bottom to top within the release tank 450 and are sequentially cut by a three-stage process involving a first perforated plate 441, a cutting blade 442, and a second perforated plate 443, thus breaking the bubbles into smaller and denser microbubbles. In this embodiment, the release tank 450 is coaxially arranged with the reaction chamber 410, and the bottom end of the release tank 450 has a second opening 454, which is sealed by the bottom wall of the reaction chamber 410.

[0035] like Figure 2 and Figure 3 As shown, the first perforated plate 441, the second perforated plate 443, and the cutting blade 442 are coaxially arranged. The outer diameter of the second perforated plate 443 is larger than the outer diameter of the first perforated plate 441. The outer diameter of the first perforated plate 441 matches the size of the opening 452 of the release tank 450 to achieve an adaptive assembly between the first perforated plate 441 and the release tank 450. The outer diameter of the second perforated plate 443 matches the size of the inner diameter of the reaction chamber 410 to achieve an adaptive assembly between the second perforated plate 443 and the reaction chamber 410.

[0036] like Figure 3 As shown, in one embodiment, to facilitate the assembly and disassembly of the second porous plate 443 and the reaction chamber 410, the outer edge of the second porous plate 443 is also provided with fixing holes 445 for detachably and fixedly connecting the second porous plate 443 and the reaction chamber 410. In one embodiment, the fixing holes 445 are arc-shaped holes, and there are multiple arc-shaped holes. The multiple arc-shaped holes are distributed at intervals along the circumference of the second porous plate 443 on its outer edge, and the dividing holes 444 on the second porous plate 443 are located in the area enclosed by the multiple arc-shaped holes. Specifically, the arc-shaped holes can be used to rivet the second porous plate 443 and the reaction chamber 410. By setting the fixing holes 445 to an arc shape, it is to prevent the second porous plate 443 from being unable to be smoothly installed in the reaction chamber 410 due to processing errors.

[0037] like Figure 3 As shown, furthermore, both ends of the cutting blade 442 are provided with connecting shafts 446, which are coaxially arranged and rotatably connected to the first perforated plate 441 and the second perforated plate 443, respectively. The outer diameter of the cutting blade 442 is between the outer diameter of the first perforated plate 441 and the outer diameter of the second perforated plate 443.

[0038] like Figure 1As shown, in one embodiment, the air supply assembly 430 includes a Venturi tube 432. The air inlet end of the Venturi tube 432 is exposed to the outside, the water inlet end of the Venturi tube 432 is connected to the pump body 420, and the air outlet end of the Venturi tube 432 is connected to the reaction chamber 410. Specifically, the Venturi tube 432 has a natural air intake function, which can use the pressure difference generated by the liquid flow in the Venturi tube 432 to draw in external air and input the drawn-in air into the water conveyed by the pump body 420. This eliminates the need for additional electromechanical equipment such as fans and air pumps in the protein separator 400, and ensures that the dissolved air water output by the pump body 420 ultimately releases microbubbles, while effectively reducing the operating energy consumption of the protein separator 400.

[0039] Specifically, the pump body 420 has a water outlet pipe 421, and the water outlet end of the pump body 420 is located at the end of the water outlet pipe 421 away from the pump body 420. The water inlet end of the venturi tube 432 is connected to the water outlet pipe 421. The venturi tube 432 has a natural air intake function, which can use the pressure difference generated by the liquid flow in the venturi tube 432 to draw in external air and input the drawn air into the water body transported by the water outlet pipe 421 of the pump body 420 to form dissolved air water. The dissolved air water is input into the reaction chamber 410 through the air outlet end of the venturi tube 432 for subsequent bubble release.

[0040] like Figure 2 As shown, in one embodiment, the protein separator 400 further includes a water distribution component 460, which is disposed within the reaction chamber 410 and connected to the liquid inlet pipe 411 to improve the water distribution area and water distribution uniformity. In one embodiment, the water distribution component 460 includes a water distribution chamber 462, which is located above the second porous plate 443 and is coaxially arranged with the second porous plate 443. The bottom end of the water distribution chamber 462 is provided with a plurality of spaced water distribution holes 464.

[0041] like Figure 1 As shown, in one embodiment, the protein separator 400 further includes an exhaust pipe 470, which is connected to the liquid outlet pipe 412. Specifically, one end of the exhaust pipe 470 is connected to the liquid outlet pipe 412, and the other end of the exhaust pipe 470 extends upward. The exhaust pipe 470 is used to discharge the gas stagnating in the liquid outlet pipe 412 to avoid the problem of poor water flow due to gas stagnation in the liquid outlet pipe 412.

[0042] like Figure 1 and Figure 2 As shown, in one embodiment, the protein separator 400 further includes a transparent observation tube 480, which is connected to the side wall of the reaction chamber 410. Specifically, one end of the transparent observation tube 480 is connected to the side wall of the reaction chamber 410, and the other end of the transparent observation tube 480 extends upward. The transparent observation tube 480 is used for operators to observe the operation inside the reaction chamber 410.
