Description

Technical Field

[0001] This invention relates to the field of marine aquaculture technology, and in particular to a wastewater purification process and equipment for marine aquaculture. Background Technology

[0002] Marine aquaculture is a production method that uses shallow seas, tidal flats, harbors, and enclosed ponds to raise and breed marine economic plants and animals. It is one of the important ways for humans to utilize marine biological resources and develop marine aquaculture. Marine aquaculture generates a large amount of wastewater, which needs to be treated.

[0003] Existing wastewater treatment equipment cannot separate the container from the filter section when filtering wastewater. When a large amount of impurities are filtered out, it cannot be cleaned in time, causing blockage of the filter section and affecting the filtration effect. Summary of the Invention

[0004] The problem solved by this invention is to provide a device for purifying wastewater used in marine aquaculture. This invention addresses the technical problem that existing wastewater treatment equipment cannot separate the container from the filter section during wastewater filtration, and cannot clean the filter section in a timely manner when a large amount of impurities are filtered out, causing blockage of the filter section and thus affecting the filtration effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wastewater purification process for marine aquaculture includes the following steps:

[0007] S1. Wastewater is transported to the cylinder by a water pump for filtration. When the rotating motor is working, it drives the rotating arm to swing. The purification plate installed on the rotating arm rotates with the rotating arm. When the purification plate is attached to the bottom of the cylinder, the wastewater is purified through the purification plate.

[0008] S2. When the purification plate and the cylinder are attached together, the cylinder acts on the ring plate, which drives the connecting rod and the first piston to move down and compress the first spring, forcing the air in the inner cavity into the air storage cylinder. When the air enters the air storage cylinder, the air storage cylinder is subjected to the air pressure. Since the second piston is connected to the lifting shaft, when the second piston moves up, the lifting shaft moves up with the second piston, and the rotating seat in contact with the lifting shaft moves up. At the same time, the second piston compresses the second spring.

[0009] S3. When the flip motor rotates in the opposite direction, the purification plate separates from the cylinder under the action of the flip motor. At this time, the first and second springs are released, and the rotating seat drives the cleaning brush bristles to move down and contact the purification plate. The rotating arm rotates 180° until the lifting shaft contacts the guide column. When the lifting shaft and the guide column are connected, the second and third springs are in a compressed state. When the drive motor rotates, the guide column is engaged in the docking hole under the action of the second and third springs to achieve connection.

[0010] S4. The drive motor drives the rotating shaft and the lifting shaft to rotate synchronously. At this time, the cleaning brush cleans the purification plate. At the same time, the rotating shaft drives the rotating blade to rotate inside the U-shaped tube, and the water passes through the U-shaped tube, sleeve seat, water inlet tank, sleeve, connecting hole and lifting shaft, and finally sprays out from the spray hole.

[0011] A device for purifying wastewater from marine aquaculture includes a cylindrical body and a purification unit. The purification unit is installed at the bottom of the cylindrical body. The purification unit includes a support base fixedly connected to the cylindrical body. A purification plate is rotatably installed on one side of the support base, and a rotating seat is rotatably installed on the purification plate. The bottom of the rotating seat is provided with cleaning bristles. An installation arm is installed on the other side of the support base. A housing is installed on the installation arm, and a drive motor is installed on the top of the housing. A rotating shaft penetrating the housing and the installation arm is installed at the output end of the drive motor. A sleeve is installed at the bottom of the rotating shaft, and a guide column is elastically installed inside the sleeve.

[0012] A tilting motor is installed on the support base, and the output end of the tilting motor passes through the support base and is connected to the rotating arm.

[0013] The purification plate has a limiting groove on its top and an inner cavity inside. A first spring is installed inside the inner cavity and is connected to a first piston. Several connecting rods are installed on the first piston and a ring plate is installed at the top of each connecting rod.

[0014] An air storage cylinder is installed on the bottom side of the purification plate, and the bottom end of the air storage cylinder is connected to the bottom end of the inner cavity through an air pipe. A second piston is installed inside the air storage cylinder, and a second spring is installed on the second piston. The top end of the second spring is connected to the top of the inside of the air storage cylinder. A lifting shaft is installed on the second piston through a sealed bearing.

[0015] Preferably, the bottom end of the lifting shaft is provided with a docking hole, which is adapted to the guide post; the top end of the lifting shaft is connected to the rotating seat; the bottom side of the rotating seat is provided with a plurality of spray holes; and the inside of the lifting shaft is provided with a connecting channel that communicates with the docking hole and the spray holes.

[0016] The rotating shaft is located inside the housing and has several rotating blades installed. A water inlet pipe is installed on the outside of the housing, and the outside of the housing is connected to the sleeve seat located at the bottom of the mounting arm through a U-shaped pipe. The sleeve seat and the rotating shaft are connected through a sealed bearing.

[0017] The rotating shaft has an inner hole, and a water inlet groove that communicates with the inner hole is formed on the outside of the rotating shaft and inside the sleeve seat.

[0018] A third spring is installed inside the sleeve, and the third spring is connected to the guide post. A connection hole is opened inside the guide post.

[0019] The beneficial effects of this invention are: the rotating motor drives the purification plate to rotate between the cylinder and the purification unit, realizing the cooperation between the purification plate and the purification unit. At the same time, when the purification plate and the purification unit are docked, the cylinder acts on the ring plate to drive the connecting rod and the first piston to move down, compressing the first spring and forcing the air in the inner cavity into the air storage cylinder, driving the second piston and the lifting shaft to move up, compressing the second spring. At this time, the rotating seat moves up, and the cleaning brush bristles are suspended on the purification plate, avoiding obstruction of the purification plate and ensuring that the filtration area of ​​the purification plate is sufficient.

[0020] When the rotating motor drives the purification plate to rotate and separate from the cylinder, the first and second springs return to their original positions. The rotating seat drives the cleaning brush bristles to move down and contact the purification plate. The rotating arm rotates 180° until the lifting shaft contacts the guide column, compressing the second and third springs respectively. When the drive motor rotates, the guide column, under the action of the second and third springs, engages with the docking hole to achieve connection. The drive motor drives the rotating shaft and the lifting shaft to rotate synchronously. At this time, the purification plate is cleaned by the cleaning brush bristles. At the same time, the rotating shaft drives the rotating blade to rotate inside the U-shaped tube, passing water through the U-shaped tube, sleeve seat, water inlet tank, sleeve, connecting hole and lifting shaft, and finally spraying it out from the spray hole, realizing automatic cleaning of the purification plate and ensuring that the purification plate is thoroughly cleaned, which is conducive to excellent filtration effect after subsequent assembly with the cylinder.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Specific implementation examples are given below.

[0031] See Figures 1-6 This invention relates to a wastewater purification process for marine aquaculture, characterized by comprising the following steps:

[0032] S1. Wastewater is transported to the cylinder 1 by a water pump for filtration. When the tilting motor 14 is working, it drives the rotating arm 4 to swing. The purification plate 5 installed on the rotating arm 4 rotates with the rotating arm 4. When the purification plate 5 is attached to the bottom of the cylinder 1, the wastewater is purified by the purification plate 5.

[0033] S2. When the purification plate 5 and the cylinder 1 are attached together, the cylinder 1 acts on the ring plate 20, which drives the connecting rod 19 and the first piston 18 to move down and compress the first spring 17, forcing the air in the inner cavity 16 into the air storage cylinder 21. When the air enters the air storage cylinder 21, the air storage cylinder 21 is subjected to the air pressure. Since the second piston 24 is connected to the lifting shaft 22, when the second piston 24 moves up, the lifting shaft 22 moves up with the second piston 24, and the rotating seat 6 in contact with the lifting shaft 22 moves up. At the same time, the second piston 24 compresses the second spring 23.

[0034] S3. When the flip motor 14 rotates in the reverse direction, the purification plate 5 separates from the cylinder 1 under the action of the flip motor 14. At this time, the first spring 17 and the second spring 23 are released. The rotating seat 6 drives the cleaning brush 7 to move down and contact the purification plate 5. The rotating arm 4 rotates 180° until the lifting shaft 22 contacts the guide column 13. When the lifting shaft 22 and the guide column 13 are connected, the second spring 23 and the third spring 32 are in a compressed state. When the drive motor 10 rotates, the guide column 13 is engaged in the docking hole 25 under the action of the second spring 23 and the third spring 32 to achieve connection.

[0035] S4. Drive motor 10 drives rotating shaft 11 and lifting shaft 22 to rotate synchronously. At this time, the cleaning brush 7 cleans the purification plate 5. At the same time, rotating shaft 11 drives rotating blade 29 to rotate inside U-shaped tube 28. Water passes through U-shaped tube 28, sleeve seat 34, water inlet trough 31, sleeve 12, connecting hole 33 and lifting shaft 22, and finally sprays out from spray hole 26, realizing automatic cleaning of purification plate 5, ensuring that purification plate 5 is thoroughly cleaned, which is conducive to excellent filtration effect after subsequent assembly with cylinder 1.

[0036] The present invention also relates to a device for purifying wastewater for marine aquaculture, comprising a cylinder 1 and a purification unit 2.

The operation of the flip motor 14 realizes the rotation of the rotating arm 4 and the purification plate 5, thereby realizing the cooperation between the purification plate 5 and the cylinder 1. Specifically, the cooperation between the purification plate 5 and the cylinder 1 is as follows: the purification plate 5 is rotated to the lower opening of the cylinder 1, and does not move up and down inside the cylinder 1.

[0037] A rotating base 6 is rotatably mounted on the purification plate 5, and a cleaning brush bristle 7 is provided at the bottom of the rotating base 6. A limit groove 15 is opened at the top of the purification plate 5, and an inner cavity 16 is opened inside the purification plate 5. A first spring 17 is installed in the inner cavity 16 and is connected to a first piston 18. Several connecting rods 19 are installed on the first piston 18, and a ring plate 20 is installed at the top of the connecting rods 19. An air storage cylinder 21 is installed on the bottom side of the purification plate 5, and the bottom end of the air storage cylinder 21 is connected to the bottom end of the inner cavity 16 through an air pipe. A second piston 24 is installed inside the air storage cylinder 21, and a second spring 23 is installed on the second piston 24. The top end of the second spring 23 is connected to the air storage cylinder 21. The top of the internal structure is connected to the second piston 24, which is equipped with a lifting shaft 22 via a sealed bearing. When the purification plate 5 and the cylinder 1 are engaged, the cylinder 1 acts on the ring plate 20 to drive the connecting rod 19 and the first piston 18 to move downward, compressing the first spring 17 and forcing the air in the inner cavity 16 into the air storage cylinder 21. This causes the second piston 24 and the lifting shaft 22 to move upward, compressing the second spring 23. At this time, the rotating seat 6 moves upward, and the cleaning brush 7 is suspended on the purification plate 5 to avoid obstructing the purification plate 5. When the purification plate 5 is separated from the cylinder 1, the first spring 17 and the second spring 23 return to their original positions, and the rotating seat 6 drives the cleaning brush 7 to move downward and contact the purification plate 5.

The sleeve seat 34 is connected to the rotating shaft 11 via a sealed bearing. An inner hole 30 is provided inside the rotating shaft 11, and a [missing information - likely a hole or opening] is provided on the outside of the rotating shaft 11 and inside the sleeve seat 34. The water inlet trough 31 is connected to the inner hole 30. The sleeve 12 is equipped with a third spring 32, which is connected to the guide post 13. The guide post 13 has a connecting hole 33. The rotating arm 4 rotates 180° until the lifting shaft 22 contacts the guide post 13 and compresses the second spring 23 and the third spring 32 respectively. When the drive motor 10 rotates, the guide post 13 is engaged in the docking hole 25 under the action of the second spring 23 and the third spring 32 to achieve connection. The drive motor 10 drives the rotating shaft 11 and the lifting shaft 22 to rotate synchronously. At this time, the cleaning brush 7 cleans the purification plate 5. At the same time, the rotating shaft 11 drives the rotating blade 29 to rotate in the U-shaped tube 28, so that the water passes through the U-shaped tube 28, the sleeve seat 34, the water inlet trough 31, the sleeve 12, the connecting hole 33 and the lifting shaft 22, and finally sprays out from the spray hole 26 to achieve automatic cleaning of the purification plate 5, ensuring that the purification plate 5 is thoroughly cleaned, which is conducive to excellent filtration effect after subsequent assembly with the cylinder 1.
