[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0040] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0041] Example 1

[0042] Please see Figure 1-4 The present invention provides a technical solution: a purification device for utilizing algae in livestock and poultry wastewater, comprising an algae treatment tank 1, wherein the algae treatment tank 1 includes:

[0043] The container 11 has circular through holes on its bottom and right side for holding algae and livestock wastewater. A support is fixedly connected to the bottom of the container 11. A pressure sensor is installed inside the container 11 to detect the gas pressure inside the container 11.

[0044] A light-transmitting top cover 12 is fixedly connected to the top of the housing 11. Two fan-shaped tempered glass panels are fixedly connected to the top of the light-transmitting top cover 12. The tempered glass panels can be detached and installed to seal the housing 11.

[0045] A layered mixing rack 13 is rotatably connected to the inside of the receiving tank 11. It is used to move the green algae and promote full contact between the algae and the livestock wastewater. The layered mixing rack 13 includes a base frame 131 with a circular through hole at its bottom. The bottom of the base frame 131 is rotatably connected to the circular through hole at the bottom of the receiving tank 11. An inner through pipe 132 is fixedly connected to the top of the base frame 131, with its bottom communicating with the circular through hole at the bottom of the base frame 131. An outer through pipe 133 is fixedly connected to the top of the base frame 131, and an outer mixing blade 134 is fixedly connected to the top of the base frame 131. Elastic mixing blades 13 are fixedly connected to both the inner and outer surfaces of the outer mixing blade 134. 5. The bottom of the base frame 131 is connected to the bottom through pipe 136. The central axis of the base frame 131, the inner through pipe 132, and the outer through pipe 133 coincide. The surfaces of the inner through pipe 132 and the outer through pipe 133 are connected to circular through holes. The top cross section of the outer stirring blade 134 is a right trapezoid. The outer stirring blade 134 is located outside the outer through pipe 133. There are four outer stirring blades 134, which are evenly distributed on the top of the base frame 131. The top cross section of the elastic stirring blade 135 is triangular. The elastic stirring blade 135 is made of silicone and is used to disturb the water flow to promote the flow of green algae. The bottom through pipe 136 has a rectangular through hole on the front. The bottom of the bottom through pipe 136 is fixedly connected to the servo motor 5.

[0046] The bottom of the housing 11 is connected to the water outlet ring 14. The inside of the water outlet ring 14 is rotatably connected to the bottom pipe 136. The back of the water outlet ring 14 is connected to the treated wastewater collection mechanism.

[0047] The top of the light-transmitting top cover 12 is connected to the algae collection box 2, the top of the light-transmitting top cover 12 is connected to the wastewater inlet pipe 3, the bottom of the wastewater inlet pipe 3 is connected to the waste residue extraction box 4, the bottom of the algae treatment box 1 is fixedly connected to the servo motor 5, and the front of the bottom support of the housing 11 is fixedly connected to the electrical control box 6.

[0048] Before starting the device, remove the tempered glass plate from the top of the light-transmitting top cover 12. Evenly add green algae and some culture medium into the gaps between the container 11 and the external pipe 133, and between the internal pipe 132 and the external pipe 133 inside the container 11. After adding the algae, reinstall the tempered glass plate. Then connect the external wastewater inlet to the wastewater feed pipe 3, and connect the wastewater recovery pipe to the outlet ring 14. Then start the device through the electrical control box 6. Livestock wastewater enters the container 11 after being treated through the wastewater feed pipe 3. Simultaneously, the wastewater feed pipe 3, under the control of the electrical control box 6, controls the inflow rate to prevent the wastewater level from exceeding the right-side through-hole of the container 11, and to mix with the green algae and its culture medium. After starting, the electrical control box 6 controls the servo motor 5 to rotate. The servo motor 5 drives the layered stirring rack 13 to rotate through the bottom pipe 136. The layered stirring rack 13 drives the outer stirring blade 134 and the elastic stirring blade 135 to rotate. The outer stirring blade 134 and the elastic stirring blade 135 agitate the wastewater inside the container 11, thereby causing the wastewater inside the container 11 to flow. The flow of wastewater causes the green algae to flow, so that the green algae inside the container 11 can receive light through the tempered glass bottom. During this process, the green algae absorb nutrients from the wastewater and produce oxygen, which leads to an increase in the gas pressure inside the container 11. At this time, the pressure sensor inside the container 11 transmits the pressure data back to the electrical control box 6. When the gas pressure value inside the container 11 reaches the pressure range after the green algae absorb and produce gas, the electrical control box 6 controls the servo motor 5 to stop rotating. The servo motor 5 drives the layered stirring rack 13 to stop rotating. At this time, the wastewater recovery channel is opened. The wastewater treated by the green algae and some of the gas produced by the green algae pass through the circular through holes of the outer pipe 133 and the inner pipe 132, and flow into the water outlet ring 14 from the bottom pipe 136, and then flow out of the device from the water outlet ring 14.

[0049] Example 2

[0050] Please see Figure 1-8Based on Embodiment 1, the present invention provides a technical solution: the algae collection box 2 includes a lifting box 21, which is made of stainless steel. The lifting box 21 includes a lifting cover 211, the bottom of which is fixedly connected to the top of the light-transmitting top cover 12. The bottom of the lifting cover 211 is connected to the top of the light-transmitting top cover 12. A bottom inclined plate 212 is fixedly connected to the bottom of the inner wall of the lifting cover 211. One side of the bottom inclined plate 212 has a triangular cross-section. A light rod 213 is fixedly connected to the left side of the inner wall of the lifting cover 211. A steel cable winch 214 is rotatably connected to the surface of the light rod 213. A steel cable is wound on the surface of the steel cable winch 214 for driving the vertical movement of the retrieval net box 23. One end of the steel cable is fixedly connected to the surface of the steel cable winch 214. 4. A pulley is fixedly connected to the left side. A motor with a pulley is fixedly connected to the back of the inner wall of the lifting cover 211. The motor is electrically connected to the electrical control box 6 through a wire. The pulley of the steel cable winch 214 is connected to the pulley of the motor through a belt. Limiting strips 215 are fixedly connected to both sides of the inner wall of the lifting cover 211. A rubber strip is fixedly connected to the front of the limiting strip 215. A displacement sensor 216 is fixedly connected to the left side of the inner wall of the lifting cover 211. The top of the displacement sensor 216 is electrically connected to the electrical control box 6 through a wire. The displacement sensor 216 is located on the back of the limiting strip 215. A collection box 22 is fixedly connected to the front of the lifting cover 211 for collecting the salvaged green algae. The front panel of the collection box 22 is detachable.

[0051] A slidable retrieval net box 23 is attached to the bottom of the inner wall of the lifting outer cover 211. The retrieval net box 23 is made of stainless steel and is used to retrieve green algae. The retrieval net box 23 includes an outer box 231. A connecting top plate 235 is fixedly connected to the top of the outer box 231. The top of the connecting top plate 235 is fixedly connected to the other end of the steel cable of the steel cable winch 214. An inner box 232 is fixedly connected to the bottom of the connecting top plate 235. The outer box 231 is located to the left of the inner box 232 and there is a certain gap. Rectangular through holes are opened on the back of the outer box 231 and the inner box 232. Inclined water storage boxes 233 are fixedly connected to the bottom of both the outer box 231 and the inner box 232. The top of the inclined water storage box 233 is an inclined surface with a circular through hole. The interior of the inclined water storage box 233 is a hollow structure. A rectangular through hole is opened on the back of the inclined water storage box 233. A rubber sealing plate 234 is fixedly connected to the bottom of the inclined water storage box 233.

[0052] During use, in the stirring process of Example 1, as the green algae absorb nutrients from the wastewater and grow and reproduce, the number of green algae increases. Consequently, the resistance encountered by the servo motor 5 driving the layered stirring frame 13 to rotate and stir increases. While maintaining a constant rotation speed, its input current increases. When the current input to the servo motor 5 increases to a certain range, the electrical control box 6 controls the motor inside the lifting cover 211 to start. After the motor starts, it drives the steel cable winch 214 to rotate via a belt. The rotation of the steel cable winch 214 releases the steel cable, which drives the retrieval net box 23 to fall. During the fall, wastewater flows into the top of the inclined water storage box 233 and flows out from the back of the inclined water storage box 233. However, wastewater is always retained inside the inclined water storage box 233, thereby lowering the center of gravity of the inclined water storage box 233. The inclined water storage box 233 is relatively stable in the wastewater inside the container 11. At this time, as the layered stirring rack 13 continues to rotate, it drives the wastewater to flow, which in turn drives the algae to flow. Some of the algae are trapped when they enter the outer container 231. Then, the electrical control box 6 controls the motor inside the lifting cover 211 to reverse, which in turn causes the steel cable winch 214 to reverse. The steel cable begins to be retrieved, and the steel cable drives the retrieval net box 23 to rise. The trapped algae move upward together with the retrieval net box 23. When the retrieval net box 23 is completely reset, the retrieval algae falls under the action of gravity and slides along the top of the inclined water storage box 233 and the top of the bottom inclined plate 212 into the collection box 22. The staff removes the front panel of the collection box 22 to remove the retrieval algae for subsequent processing.

[0058] During operation, after the device is started, the motor starts, driving the grinding chamber 312 and the eccentric trigger wheel 34 to rotate.

Subsequently, the wastewater passes through the grinding chamber 312 and the vertical pipe 311 into the receiving tank 11, starting the algae treatment process in Examples 1 and 2. During the process of entering the receiving tank 11, solid impurities in the wastewater are intercepted by the baffle 314 and the vertical baffle 315, and are crushed by the grinding chamber 312 during rotation. The crushed solid impurities, under the action of gravity, pass through the vertical baffle 315 and the feed slide 413 with part of the wastewater. As the solid impurities enter the sedimentation tank 411, they eventually fall onto the top of the guide plate 415. At this time, due to the rotation of the eccentric trigger wheel 34, the extrusion slider 42 slides back and forth in the vertical direction. The bottom of the wedge-shaped extrusion head 424 extrudes the solid impurities. At the same time, the ultrasonic transmitter 43 emits ultrasonic waves to the solid impurities to further kill the microorganisms they carry. Some of the nutrients in the solid impurities, along with the extruded juice and the flowing wastewater, pass through the slag baffle 414 and the diverting pipe 412 and enter the one-way valve 44. When the pressure of the liquid and wastewater squeezed by the solid impurities inside the one-way valve 44 is greater than its closing pressure, the one-way valve 44 connects the receiving tank 11 and the diverting pipe 412. The liquid generated by the extrusion of the solid impurities enters the receiving tank 11 and mixes with the wastewater. The nutrients in the liquid are absorbed by the green algae.
