Description

Technical Field

[0001] This invention belongs to the field of pollution control technology for livestock and poultry farming, specifically relating to the field of wastewater treatment technology for aquaculture in supermarkets, and in particular to a wastewater filtration and purification device for aquaculture. Background Technology

[0002] In aquaculture operations such as supermarkets, wastewater from fish and shrimp farming must be purified to meet environmental standards before being discharged. Therefore, efficiently treating ammonia nitrogen wastewater and aquatic excrement often requires consideration of ease of handling and cost control, primarily involving the following technical issues: (1) The traditional method of treating aquaculture pond wastewater involves using sponge filtration and adding drugs or microbial populations for treatment to eliminate organic and nitrogen pollution. This process often results in poor treatment effect or low efficiency due to insufficient filtration layers.

[0003] (2) For supermarkets and other business venues, frequent cleaning of aquaculture ponds will result in high labor costs and is not conducive to the display and sale of goods. In addition, it requires manual removal of aquatic products, manual cleaning of aquaculture ponds, and refilling with water. This method has the problem of a large workload.

[0004] (3) Because the water quality of aquatic products is polluted quickly during the breeding and sales process, if it is not cleaned up in time, it will cause economic losses such as the death of aquatic products. Moreover, frequent water changes are not conducive to resource conservation, which will waste water resources and increase breeding costs.

The present invention also includes a dispensing and processing mechanism that uses the kinetic energy of water to drive the water-driven fan wheel to rotate, thereby simultaneously realizing the automatic conveying and mixing of materials. This allows the ammonia in the wastewater to fully react with the materials and be converted into nitrates. The treated water is then partially recycled back to the aquaculture pond through a water circulation system, thus achieving the automation and resource recycling of wastewater treatment. This invention incorporates an oxygenation auxiliary mechanism that draws air from the outside of the treatment tank through a connected air inlet pipe and discharges it unidirectionally into the water in the front half of the inner tank through a small hole on the side of the outlet pipe, thereby increasing the oxygen content of the water. Simultaneously, the rotation of the inner rotating shaft drives the connected turntable to rotate, causing the upper magnet on the turntable to move closer to or further away from the lower magnet below. This allows the spring plate to store energy under the action of magnetic force. After the upper magnet moves away from the lower magnet as the turntable rotates, the spring plate resets under the influence of the lost magnetic force and strikes the deflector plate, generating vibration to prevent sediment from adhering to its surface and assisting the sediment to be discharged into the fan plate shell. Thus, it achieves the dual functions of water oxygenation and anti-clogging cleaning of the filter components simultaneously under the drive of a single power source. Attached Figure Description

[0019] 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.

[0020] Please see Figure 1-13 An embodiment of the present invention is: an aquaculture wastewater filtration and purification device, including an aquaculture pond 1, a treatment tank 2, a material port 3, a cultivation port 4, and a discharge port 7. The rear end of the treatment tank 2 is provided with a separation and treatment mechanism 5 for treating organic matter and intercepting solid waste in the wastewater of the aquaculture pond 1. The front end of the internal part of the treatment box 2 is equipped with a dosing and treatment mechanism 6 for treating ammonia generated in the wastewater of the aquaculture pond 1; The control module, lighting module, heating module, and temperature sensor are installed inside the aquaculture pond 1; and An external terminal that communicates with the control module; The external terminal is used to send control signals to the control module; The control module responds to the control signal by sending a light control signal to the lighting module to remotely adjust the brightness of the light in the aquaculture pond 1; The control module is also used to receive temperature data from the temperature sensor and control the working state of the heating module according to the temperature data or the control signal, so as to remotely monitor and adjust the water temperature in the aquaculture pond 1.

[0021] The separation and processing mechanism 5 includes an inner box 502. A liquid storage tank 503 is fixedly connected to the rear inner wall of the inner box 502. A porous cotton plate 504 is slidably connected to the surface of the liquid storage tank 503. A flow divider 515 is provided on the outer side of the porous cotton plate 504. A side hole end shell 516 is fixedly connected to the outer side of the flow divider 515. A permeable membrane 514 is fixedly connected to both the front and rear surfaces of the side hole end shell 516. A connecting groove end 513 is fixedly connected to the outer side of the side hole end shell 516. A side passage pipe 517 is installed on both the front and rear sides of the connecting groove end 513.

[0022] The separation and processing mechanism 5 also includes two side end shells 501, which are located on both sides of the inner box 502. One of the side end shells 501 has two liquid-driving end shells 510 installed on its inner wall. A water impeller 509 is rotatably connected inside each liquid-driving end shell 510. An output group pipe 507 is fixedly connected to the outer surface of the liquid-driving end shell 510. A water pump 506 is connected to the bottom middle part of the output group pipe 507. A liquid extraction pipe 508 is connected to the side of the water pump 506. An inlet pipe 518 is fixedly connected to the other end of the liquid-driving end shell 510.

[0023] The processing box 2 is fixedly connected to a deflector plate 505. The left and right ends of the deflector plate 505 are fixedly connected to a fan plate shell 512. The fan plate shell 512 is rotatably connected to a sealing fan plate 511.

[0024] The inner box 502 is fixedly connected to the inner wall of the treatment box 2. The water pump 506 is installed at the bottom of the deflecting guide plate 505. The minimum angle between the deflecting guide plate 505 and the horizontal line is 20 degrees. Long slots are opened on both the upper and lower sides of the fan plate shell 512, and the long slot on the upper part of the fan plate shell 512 corresponds to the position of the deflecting guide plate 505.

[0025] Multiple small holes are provided on both the left and right sides of the side end shell 516. Multiple diversion baffles 515 are equidistantly distributed and are attached to the permeable membrane 514. The inlet pipe 518 passes through the inner wall of the side end shell 501 to the inner wall of the treatment tank 2. When the water pump 506 is in working condition, the water pump 506 draws wastewater from the aquaculture pond 1 through the external connecting pipe connected to the liquid extraction pipe 508. The wastewater is transported by the water pump 506 through the connected output group pipe 507 to the inside of the liquid driving end shell 510. The wastewater passes through the inside of the liquid driving end shell 510. One side of the water turbine 509 will drive the water turbine 509 to rotate, and the rotation of the water turbine 509 will drive the coaxial sealing fan plate 511 to rotate. The rotation of the sealing fan plate 511 will cause the solid particles deposited on the deflector plate 505 to be conveyed to the bottom of the deflector plate 505 by flipping. When some wastewater and sediment need to be treated and discharged through the discharge port 7, the external drain valve connected to the discharge port 7 needs to be opened for discharge treatment. The wastewater that has been rotated by the water turbine 509 will be discharged through the inlet pipe connected to the liquid driving end shell 510. 518 enters above the guide plate 505 and, after the water level rises to the bottom of the storage tank 503, the water pump 506 continuously works to deliver wastewater above the guide plate 505, increasing the water pressure between the guide plate 505 and the storage tank 503. This water pressure forces the wastewater through the permeable membrane 514. As the water passes through the permeable membrane 514, heterotrophic bacteria from the culture medium introduced through the culture port 4 flow through the guide plate 505 into the porous cotton plate 504. After a period of time, the heterotrophic bacteria will attach to the porous... Within the porous structure of the cotton board 504, wastewater passing through the permeable membrane 514 is diverted by the diversion baffle 515 and comes into contact with the porous cotton board 504 through the gaps between the diversion baffles 515. This allows the heterotrophic bacteria attached to the porous cotton board 504 to consume the organic matter in the wastewater and convert it into dissolved waste such as ammonia. The wastewater is then discharged with the water flow through the small holes on the side of the side end shell 516 and discharged from the rear of the inner tank 502 through the side pipes 517 on both sides of the connecting tank end 513 for further treatment.

[0026] The disposal and treatment mechanism 6 includes a drainage channel 601, a side flow channel 602 connected to the front side of the drainage channel 601, a guide channel 603 opened on the side of the front half of the inner box 502, a flow lifting plate 604 fixedly connected to the inner wall of the front half of the inner box 502, an arc-shaped baffle 605 fixedly connected to the side of the flow lifting plate 604, a water-driven fan wheel 606 rotatably connected to the side of the arc-shaped baffle 605, a water-passing arc groove 609 opened on the side of the arc-shaped baffle 605, a flow intercepting plate 607 fixedly connected to the bottom surface of the front half of the inner box 502, and a water diversion channel 608 fixedly connected to the front side of the flow intercepting plate 607.

[0027] The feeding and processing mechanism 6 also includes a top material trough 610, which is fixedly connected to the top surface of the arc-shaped baffle 605. A spiral blade 611 is fixedly connected to the inner wall of the water-driven fan wheel 606, and an inner shaft cylinder 612 is fixedly connected to the inner side of the spiral blade 611.

[0028] The side flow channel 602 is located between the inner box 502 and the side end shell 501. The bottom surface of the front half of the inner box 502 is a closed structure. Wastewater discharged from the side pipe 517 is discharged through the rear side of the inner box 502 to the drain channel 601, and then flows into the side flow channel 602 through the drain channel 601 and enters the area above the lifting plate 604 through the guide channel 603. The water flow on the lifting plate 604 enters the side of the water-driven fan wheel 606 through the water arc channel 609, and the water flow pushes the water-driven fan wheel 606 to rotate slowly. As the water-driven fan wheel 606 rotates slowly, the rotating water-driven fan wheel... 606 drives the spiral blades 611 connected to the inner wall to rotate, conveying the material on the top feed trough 610 to the bottom of the inner shaft cylinder 612 through the spiral blades 611. The liquid then comes into contact with the material through the small holes on the side of the water-driven fan wheel 606. After contact, the material dissolves in the water, and the water-driven fan wheel 606 swings to mix the material with the wastewater. The material mixes with the ammonia in the wastewater to produce a nitrate solution. The treated water is then discharged through the water inlet trough 608. The water inlet trough 608 discharges part of the water back into the aquaculture pond 1 through an external water pipe, thus treating the wastewater quality of the aquaculture pond 1.

[0029] An oxygenation auxiliary mechanism 8 is provided inside the inner shaft cylinder 612. The oxygenation auxiliary mechanism 8 includes a shaft frame 801, which is fixedly connected to the inner wall of the inner shaft cylinder 612. An inner rotating shaft 802 is fixedly connected to the center of the shaft frame 801. A peristaltic handle 803 is fixedly connected to the outer surface of the inner rotating shaft 802. Three peristaltic wheels are installed on the side of the peristaltic handle 803. A flexible hose 804 is provided on the outer side of the peristaltic handle 803. A fixed end 805 is fixedly connected to the outer side of the flexible hose 804. An air inlet pipe 806 and an air outlet pipe 807 are fixedly connected to both ends of the flexible hose 804, respectively. A turntable 810 is fixedly connected to the bottom end of the inner rotating shaft 802. Four upper magnets 811 are fixedly connected to the bottom surface of the turntable 810. A lower magnet 813 is provided below the upper magnets 811. A spring plate 812 is fixedly connected to the bottom surface of the lower magnet 813. The fixed end 805 is fixedly connected to the bottom surface of the front end of the inner box 502. An air outlet is provided on the outer wall of the air outlet pipe 807, and a one-way valve structure is provided on the inner wall of the air outlet. The inner rotating shaft 802 extends from the top of the inner box 502 through the bottom surface and is rotatably connected to the inner box 502. The bottom end of the spring plate 812 is fixedly connected to the bottom surface of the inner box 502. When the inner shaft cylinder 612 rotates, it drives the shaft bracket 801 connected to the inner wall to rotate, causing the shaft bracket 801 to drive the peristaltic wheel on the peristaltic handle 803 to squeeze the air in the hose 804. At this time, the air in the hose 804 generates pressure, causing the connected air inlet pipe 806 to draw air from the outside of the treatment tank 2 and discharge it through the air outlet pipe 807. The air outlet pipe 807 then discharges the air unidirectionally into the water in the front half of the inner tank 502 through a small side hole. By introducing air into the treated water, the oxygen content in the water is increased. In addition, during the rotation of the inner shaft 802, the phase... When the turntable 810 rotates, the upper magnet 811 on the turntable 810 is aligned with the lower magnet 813 below it. The upper magnet 811 and the lower magnet 813 are attracted to each other by magnetic force. The lower magnet 813, which is close to each other, drives the connected spring plate 812 away from the contacting deflector plate 505. After the upper magnet 811 is displaced from the lower magnet 813 as the turntable 810 rotates, the spring plate 812 is no longer affected by the magnetic force and resets to strike the deflector plate 505 to prevent sediment from adhering to the deflector plate 505. The vibration of the deflector plate 505 helps the sediment to be discharged into the fan plate shell 512.

[0030] Working principle: When the water pump 506 is in operation, it draws wastewater from the aquaculture pond 1 through the external connecting pipe connected to the suction pipe 508. The wastewater is then pumped by the water pump 506 to the interior of the liquid-driving end shell 510 through the connected output pipe 507. The wastewater passing through one side of the water impeller 509 inside the liquid-driving end shell 510 drives the water impeller 509 to rotate, which in turn drives the coaxial sealing fan plate 511 to rotate. The rotation of the sealing fan plate 511 flips and transports the solid particles deposited on the deflector plate 505 to below the deflector plate 505. When some wastewater and sediment need to be treated and discharged through the discharge port 7, the external drain valve connected to the discharge port 7 needs to be opened for discharge. The wastewater, after being rotated by the water impeller 509, enters the area above the deflector plate 505 through the inlet pipe 518 connected to the liquid-driving end shell 510, and rises to the bottom of the storage tank 503. The water pump 506 continuously pumps wastewater above the deflector plate 505, increasing the water pressure between the deflector plate 505 and the storage tank 503. The water pressure forces the wastewater through the permeable membrane 514. As the water passes through the permeable membrane 514, the heterotrophic bacteria in the culture medium introduced through the culture port 4 flow into the porous cotton plate 504 through the deflector plate 505. After a period of time, the heterotrophic bacteria attach to the porous structure inside the porous cotton plate 504. At this time, the wastewater passing through the permeable membrane 514 is diverted through the diversion baffle 515 and contacts the porous cotton plate 504 through the gaps between the diversion baffles 515. This allows the heterotrophic bacteria attached to the porous cotton plate 504 to consume the organic matter in the wastewater and convert the organic matter into dissolved waste such as ammonia. The wastewater is discharged with the water flow through the small holes on the side of the side end shell 516 and discharged from the rear of the inner tank 502 through the side pipes 517 on both sides of the connecting tank end 513 for further treatment. Wastewater discharged from the side pipe 517 is discharged through the rear of the inner tank 502 to the drain trough 601, and then flows into the side channel 602 through the drain trough 601 and enters the area above the lifting plate 604 through the guide channel 603. The water flow on the lifting plate 604 enters the side of the water-driven fan wheel 606 through the water arc groove 609, and the water flow pushes the water-driven fan wheel 606 to rotate slowly. At the same time, the rotating water-driven fan wheel 606 drives the spiral blades 611 connected to the inner wall to rotate. The material on the top feed trough 610 is conveyed to the bottom of the inner shaft cylinder 612 through the spiral blades 611, and the liquid is allowed to come into contact with the material through the small holes on the side of the water-driven fan wheel 606. After contact, the material is soluble with water, and the material is mixed with the wastewater by the swing of the water-driven fan wheel 606. The material is mixed with the ammonia in the wastewater to produce nitrate solution. The treated water is discharged through the water inlet trough 608. The water inlet trough 608 discharges part of the water back into the aquaculture pond 1 through the external water pipe, which plays the role of treating the wastewater quality of the aquaculture pond 1. When the inner shaft cylinder 612 rotates, it drives the shaft bracket 801 connected to the inner wall to rotate, causing the shaft bracket 801 to drive the peristaltic wheel on the peristaltic handle 803 to squeeze the air in the hose 804. At this time, the air in the hose 804 generates pressure, causing the connected air inlet pipe 806 to draw air from the outside of the treatment tank 2 and discharge it through the air outlet pipe 807. The air outlet pipe 807 then discharges the air unidirectionally into the water in the front half of the inner tank 502 through a small side hole. By introducing air into the treated water, the oxygen content in the water is increased. In addition, during the rotation of the inner shaft 802, the connected... When the turntable 810 rotates, the upper magnet 811 on the turntable 810 is aligned with the lower magnet 813 below it. The upper magnet 811 and the lower magnet 813 are attracted to each other by magnetic force. The lower magnet 813, which is close to each other, drives the connected spring plate 812 away from the contacting deflector plate 505. After the upper magnet 811 is displaced from the lower magnet 813 as the turntable 810 rotates, the spring plate 812 is no longer affected by the magnetic force and resets to strike the deflector plate 505 to prevent sediment from adhering to the deflector plate 505. The vibration of the deflector plate 505 helps the sediment to be discharged into the fan plate shell 512.
