DETAILED DESCRIPTION

[0032] The present application will be further described in detail below with reference to the drawings.

[0033] The present embodiment is only an explanation of the present application, and it is not a limitation of the present application, and those skilled in the art can make modifications to the present embodiment without creative contribution after reading the present specification, but as long as it is within the scope of the claims of the present application, it is protected by the patent law.

[0034] The present embodiment relates to a double-layer warehouse protein separator, referring to Figures 1-3 , comprising: a main warehouse body 100, a pollution collection module 200, a pump body module 300, a gas injection module 400, a first flow guide layer 500 and a second flow guide layer 600.

[0035] The main tank 100 is the main structure of the entire system, which provides space for liquid treatment. The main tank 100 is provided with a liquid outlet 120 and a liquid inlet 110. The liquid inlet 110 is connected to the first flow guide layer 500, which is used for the external liquid to flow in. The liquid outlet 120 is used to discharge the treated liquid. The pollution collection module 200 is located at the top of the main tank 100, which mainly collects the pollutants (such as proteins, fats and other organic matter) that are brought to the water surface by the rising bubbles. These pollutants will float to the surface under the action of the bubbles and be captured by the pollution collection module 200, so as to achieve the purpose of purifying water. The pump body module 300 is responsible for sucking the liquid from the main tank 100 and the first flow guide layer 500 and sending it into the second flow guide layer 600 through pressurization. At the same time, the pump body module 300 also undertakes to cooperate with the gas injection module 400 to uniformly mix the gas into the liquid to form fine and dense bubbles. The gas injection module 400 injects ozone gas into the pump body module 300, which is fully mixed with the liquid to generate a large number of small bubbles. These bubbles improve the capture efficiency of pollutants and can effectively adsorb or wrap the suspended particles in the water, especially those organic matter that is easy to adhere to the surface of the bubbles. The first flow guide layer 500 guides the flow direction of the liquid to ensure that the liquid can be uniformly distributed and effectively contacted with the subsequent reaction stage. In addition, the first flow guide layer 500 also plays a certain pretreatment role, such as allowing larger solid impurities to settle down first. The second flow guide layer 600 is one of the key reaction areas, and the liquid containing a large number of bubbles in the second flow guide layer 600 is treated in a deeper level. The bubbles continue to rise in this place, further promoting the separation of pollutants in the water and helping to remove pollutants with good solubility. When the separator starts to work, the liquid inlet 110 supplies external liquid into the first flow guide layer 500 to ensure that the liquid to be treated can enter the first flow guide layer 500 uniformly. The liquid is pumped out of the main tank 100 and the first flow guide layer 500 by the power provided by the pump body module 300. The ozone in the gas injection module 400 is mixed with the liquid in the pump body module 300 to form a large number of small bubbles, which increases the surface area of the liquid in contact with air and improves the removal efficiency of pollutants. The liquid containing bubbles is pumped by the pump body module 300 to the second flow guide layer 600, fully contacts and reacts with the pollutants in the water, and then the liquid treated by the bubbles flows from the second flow guide layer 600 to the bottom of the main tank 100 and is discharged outside the system through the liquid outlet 120. As the bubbles rise to the top of the main tank 100, the pollutants carried by the bubbles will also reach the top. These light-weight pollutants will gather at the top of the main tank 100 and enter the pollution collection module 200 through the opening at the top of the main tank 100. The pollution collection module 200 collects these pollutants for regular cleaning to prevent the pollutants from re-mixing into the treated water.The double-layer flow guide increases the contact time and area of bubbles and liquid during the entire purification process, improves the water-gas mixing efficiency, and the pump body module 300 and the gas injection module 400 can generate more bubbles, which means stronger adsorption capacity, thereby more effectively removing pollutants in the liquid, significantly improving the effect and efficiency of liquid treatment. Moreover, the injected ozone gas can also sterilize and disinfect the liquid.

[0036] In particular, in the present embodiment, with reference to Figures 3-4 , the first flow guide layer 500 and the second flow guide layer 600 are integrally formed into a flow guide bin, which is installed at the bottom of the main bin body 100 and communicates with the liquid inlet 110. The top end of the first flow guide layer 500 is provided with a first sieve plate 510, and the top end of the second flow guide layer 600 is provided with a second sieve plate 610, both of which are provided with a plurality of flow guide holes. A large number of bubbles are cut and refined by the two sieve plates, forming smaller and more intensive bubbles, increasing the contact area between bubbles and water, and improving the adsorption efficiency. At the same time, through the double action of the two sieve plates, the uniform distribution of bubbles in the entire flow guide bin is ensured, so that each area can be effectively treated.

[0037] In the present embodiment, with reference to Figures 2-3 , the pump body module 300 includes: a jet pump group 310 assembled on one side of the main bin body 100 close to the liquid outlet 120, and a needle brush pump group 320 assembled on the side of the main bin body 100 close to the jet pump group 310 and away from the liquid outlet 120. The jet pump group 310 uses the Venturi effect to cut ozone into tiny bubbles, the generated bubbles are uniformly distributed, and they are mixed with the liquid, preliminarily adsorbing the pollutants in the water. The liquid containing bubbles is delivered to the second flow guide layer 600, generating a large number of tiny bubbles, increasing the contact area between bubbles and liquid, and improving the adsorption efficiency. At the same time, the jet pump group 310 usually has a faster response speed, which can quickly adjust the lift to increase the water supply according to the needs. The needle brush pump group 320 further cuts ozone into smaller bubbles by high-speed rotating needle brush. The generated smaller bubbles have a larger surface area and can more effectively adsorb pollutants in the liquid. On the basis of the preliminary treatment by the jet pump group 310, the size and number of bubbles are further optimized, and the treatment effect is improved. Through the combined use of the jet pump group 310 and the needle brush pump group 320, the water-gas mixing efficiency is improved, multi-stage bubble generation and treatment are realized, and the overall purification effect is improved. At the same time, a large number of small bubbles are generated, which enhances the adsorption capacity of pollutants in the liquid.

[0038] Specifically in this embodiment, the needle brush pump group 320 is provided with four groups, which further improves the water-gas mixing efficiency and further refines the bubbles, thereby improving the treatment effect. The arrangement of the jet pump group 310 and the four groups of needle brush pump group 320 significantly improves the overall performance and treatment effect of the protein separator through multi-stage bubble generation and treatment. This combination not only improves the generation efficiency of the bubbles, but also enhances the mixing effect of the bubbles and water, thereby significantly improving the water purification capacity. In other embodiments, the needle brush pump group 320 can also be provided with multiple groups, which is not limited here.

[0039] In this embodiment, referring to Figures 2-4 , the jet pump group 310 includes a first liquid inlet pipe 311, a first liquid outlet pipe 312, a jet pump body 313, and a jet device 314. The first liquid inlet pipe 311 is in communication with the first flow guide layer 500 to introduce the liquid in the first flow guide layer 500 into the jet pump body 313. The first liquid outlet pipe 312 is in communication with the second flow guide layer 600 to transport the liquid (containing a large number of micro-bubbles) treated by the jet pump body 313 to the second flow guide layer 600. The jet pump body 313 is assembled between the first liquid inlet pipe 311 and the first liquid outlet pipe 312, and uses the Venturi effect to pump the liquid from the first liquid inlet pipe 311 into the first liquid outlet pipe 312, and absorbs the gas through the low-pressure area generated by the high-speed water flow to generate a large number of micro-bubbles. The jet device 314 is arranged on the first liquid outlet pipe 312, and through the Venturi effect, a low-pressure area is formed when the liquid flows at high speed, thereby absorbing the ozone gas of the gas injection module 400, and cutting the gas into micro-bubbles, which are mixed with the liquid and transported to the second flow guide layer 600. In the second flow guide layer 600, the bubbles and the liquid are further mixed and reacted to adsorb the dirt in the water. The jet pump body 313 and the jet device 314 can generate a large number of micro-bubbles, increase the contact area between the bubbles and the water body, and improve the adsorption efficiency.

[0040] In this embodiment, the gas injection module 400 is in communication with the first gas injection pipe 410 arranged on the jet device 314. One end of the first gas injection pipe 410 is connected to the external ozone gas, and the other end is in communication with the jet device 314 as a gas transmission channel to safely and stably transport the gas to the jet device 314. Specifically, the end of the first gas injection pipe 410 in communication with the jet device 314 extends upward to the top end of the main chamber body 100, then bends downward, and extends until the other end is flush with the jet device 314, which can reduce the pressure loss in the gas transmission process, ensure that the gas can be stably transported to the jet device 314, and help prevent backflow of the gas during the transmission process. The first gas injection pipe 410 is also provided with two interfaces, which can flexibly adjust the input amount of the gas. More specifically, the first gas injection pipe 410 can also be equipped with a flow controller, which can further adjust the flow and pressure of the gas to adapt to different treatment needs.

[0041] Further, the first liquid inlet pipe 311 and the first liquid outlet pipe 312 are provided with a first regulating valve 315. The first regulating valve 315 can adjust the liquid flow entering the jet pump body 313, and can also be used to adjust the pressure in the pipeline to adapt to the processing requirements under different conditions.

[0042] In the embodiment, referring to Figures 2-4 , the needle brush pump group 320 includes a second liquid inlet pipe 321, a second liquid outlet pipe 322, and a needle brush pump body 323. The second liquid inlet pipe 321 communicates with the main tank body 100 to suck the liquid in the main tank body 100 and introduce it into the needle brush pump body 323. The second liquid outlet pipe 322 communicates with the second flow guide layer 600 to transport the liquid bubbles processed by the needle brush pump body 323 to the second flow guide layer 600. The needle brush pump body 323 is assembled between the second liquid inlet pipe 321 and the second liquid outlet pipe 322, and cuts the gas into very small bubbles by high-speed rotation of the needle brush, and mixes it with the water flow. The gas injection module 400 communicates with the second liquid inlet pipe 321 and injects ozone gas. The second liquid inlet pipe 321 sucks the liquid and gas in the main tank body 100 into the needle brush pump body 323. In the needle brush pump body 323, the high-speed rotating impeller cuts the ozone gas into very small bubbles and mixes it with the liquid. The liquid containing a large number of small bubbles is pumped into the second flow guide layer 600 through the second liquid outlet pipe 322. The bubbles and the liquid are further mixed and react to adsorb the dirt in the water, further improving the processing effect.

[0043] Further, the second liquid inlet pipe 321 and the second liquid outlet pipe 322 are provided with a second regulating valve 324. The second regulating valve 324 can also adjust the liquid flow entering the needle brush pump body 323.

[0044] In the embodiment, referring to Figure 3 , the gas injection module 400 further includes a second gas injection pipe 420 and a third gas injection pipe 430. The second gas injection pipe 420 is used to access an external gas source (ozone generator) to provide an additional gas input path to ensure sufficient gas supply for the system. One end of the third gas injection pipe 430 communicates with the top end of the dirt collection module 200, and the other end communicates with the second liquid inlet pipe 321. The third gas injection pipe 430 re-introduces the unreacted gas collected from the top of the dirt collection module 200 into the second liquid inlet pipe 321, achieving recycling of the gas. These unreacted gases enter the needle brush pump body 323 again and mix with newly introduced liquid to continue participating in the bubble generation and adsorption process, improving the utilization rate of the gas and reducing waste. At the same time, the ozone residual gas left in the main tank body 100 will not cause corrosion or erosion to the protein separator, affecting the service life of the separator.

[0045] In the embodiment, referring to Figures 2-3The pollution collection module 200 comprises a pollution collection bin 210 sleeved on the top end of the main bin body 100 and a pollution discharge port 220 communicated with the bottom of the pollution collection bin 210 and used for discharging the pollution in the pollution collection bin 210. The pollution collection bin 210 is a pollution collection area and is responsible for collecting the overflowed bubbles and the organic matters carried by the bubbles from the main bin body 100. The pollution discharge port 220 is opened regularly or as needed to discharge the pollution in the pollution collection bin 210 and prevent the pollution from accumulating too much to affect the system operation.

[0046] Further, the pollution collection module 200 is provided with a sweeping member 230 on the side of the top end of the main bin body 100 and used for sweeping the overflowed bubbles into the pollution collection bin 210. The sweeping member 230 sweeps the overflowed bubbles from the main bin body 100 into the pollution collection bin 210 by a physical or mechanical method (such as a rotating brush, a scraper or the like), ensures that all the bubbles can be effectively collected and avoids the bubbles from re-entering the main bin body 100, thereby improving the pollution collection efficiency.

[0047] The above is only used for describing the technical scheme of the utility model and not for limiting, and other modifications or equivalent replacements of the technical scheme of the utility model made by the ordinary skilled in the art should be covered in the claim range of the utility model as long as the modifications or the equivalent replacements do not depart from the spirit and the range of the technical scheme of the utility model.
