Description

Technical Field

[0001] This invention belongs to the technical field of wastewater treatment equipment, and in particular relates to a purification and treatment equipment for aquaculture wastewater. Background Technology

[0002] Aquaculture wastewater purification is a crucial measure for improving the aquaculture environment and protecting aquatic ecosystems. Wastewater is rich in pollutants such as uneaten feed and feces; direct discharge will damage water quality. Various purification methods exist: physical treatment removes large particles through sedimentation and filtration; chemical treatment utilizes oxidation and coagulation to degrade harmful substances; and biological treatment relies on microorganisms to decompose organic matter, such as constructing artificial wetlands that utilize aquatic plants and microorganisms for synergistic purification. Other methods include ecological ditches. Scientific wastewater purification enables water resource recycling, reduces pollution to surrounding water bodies, and promotes the sustainable development of aquaculture.

[0003] A Chinese patent application (or patent) with publication number CN221460163U discloses a wastewater purification device for aquaculture, including a purification tank, a sedimentation tank, and a filtration tank. The purification tank is provided with a filter plate at its upper end, and the filter plate is provided with a cleaning mechanism. The cleaning mechanism includes a first servo motor, the output end of which is connected to a first bevel gear. The first bevel gear is meshed with a second bevel gear, and a first connecting rod is welded to the second bevel gear. The first connecting rod is welded to both ends with a first connecting disc.

[0004] However, the above-mentioned device still has the following problems during implementation: In the filtration stage of aquaculture wastewater purification, mixing blades are used to agitate the wastewater to mix the chemicals, allowing them to fully contact and react with the wastewater, thus improving the purification effect. However, this method has certain limitations. The mixing blades are fixed in position and can only function in specific areas, failing to fully cover the entire wastewater treatment space. This results in a limited mixing range, where wastewater and chemicals in some areas cannot be fully mixed, affecting the efficiency and quality of subsequent purification processes.

[0005] To address these issues, we provide an aquaculture wastewater purification and treatment device. Summary of the Invention

[0009] The present invention is further configured such that the drive assembly further includes a first bevel gear mounted on the surface of the drive rod and a second bevel gear mounted on the bottom of the rotating rod, wherein the first bevel gear and the second bevel gear mesh with each other.

[0010] The present invention is further configured such that a first spring is sleeved on the surface of the square rod, one end of the first spring is fixedly connected to the rotating shaft, and the other end of the drive rod is fixedly connected to the filter cylinder.

[0011] The present invention is further configured such that a sludge inlet pipe is connected to one side of the mixing tank, and the surface of the toothed ring is fixedly connected to the inner wall of the mixing tank.

[0012] The present invention is further configured such that a drain pipe is connected to one side of the mixing tank, an electromagnetic valve is sleeved on the surface of the drain pipe, and the other end of the drain pipe is connected to the support cylinder.

[0013] The invention is further configured such that a cam is fixedly connected to the surface of the rotating rod, a push plate is slidably connected to one side of the cam, a cleaning brush plate is fixedly connected to the other side of the push plate, and the other end of the cleaning brush plate extends through the inside of the support cylinder.

[0014] The invention is further configured such that a second spring is sleeved on the surface of the cleaning brush plate, and one end of the second spring is fixedly connected to the push plate.

[0015] The present invention is further configured such that a water storage tank is fixedly connected to one side of the support cylinder, a pressurized water pump is connected to one side of the water storage tank, a water spray pipe is connected to the other end of the pressurized water pump, and the other end of the water spray pipe extends into the filter cylinder and is connected to a nozzle.

[0016] The present invention is further configured such that a support shell is fixedly connected to the bottom of the support cylinder, a metal filter screen is fixedly connected inside the support shell, and a sedimentation tank is fixedly connected to one side of the support shell.

[0017] The present invention is further configured such that a bracket is fixedly connected to one side of the drive motor, and the top of the bracket is fixedly connected to the mixing tank.

[0018] The present invention has the following beneficial effects.

[0019] 1. This invention achieves three-dimensional mixing through the linkage structure of the rotating disk and rotating shaft with the mixing blades. The drive gear and gear ring in the adjustment component mesh, allowing the mixing blades to move up and down while rotating, thus expanding the mixing range. This dynamic adjustment mechanism ensures that the reagent and wastewater can fully contact and react in all areas of the mixing tank, solving the problem of uneven mixing in traditional fixed mixers. The structural design of the square rod and slider ensures the stability of height adjustment, and the setting of the first spring enables the automatic reset of the mixing blades, forming a periodic mixing mode. This all-round mixing method makes the flocculation reaction more thorough, providing a better pretreatment effect for subsequent filtration processes, and improving the overall effluent purification efficiency and water treatment quality.

[0020] 2. The filtration system of this invention achieves continuous and efficient operation through a unique drive and cleaning structure. The drive motor drives the stirring system and the filter cartridge to rotate simultaneously through a bevel gear set, while the cam and push plate mechanism drive the cleaning brush to reciprocate and scrape the surface of the filter cartridge. Combined with the reverse flushing of the spray head, this effectively prevents the filter holes from clogging. The constant pressure maintained by the second spring ensures close contact between the cleaning brush and the filter cartridge. The secondary filtration design of the metal filter screen and sedimentation tank further improves the quality of the effluent. This self-cleaning mechanism allows the filter cartridge to maintain its optimal filtration state without interrupting the processing, avoiding the problem of traditional equipment requiring shutdown for cleaning. This significantly improves the continuous operating time and processing capacity of the equipment, making it particularly suitable for the continuous purification needs of large-scale aquaculture wastewater.

[0021] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0032] The technical solutions of the present invention will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Example 1: Please refer to Figures 1-8This invention relates to an aquaculture wastewater purification and treatment device, comprising a mixing tank 1, a rotating disk 2 movably connected to the top of the mixing tank 1, a rotating shaft 3 movably connected inside the rotating disk 2, a square rod 4 slidably connected inside the rotating shaft 3, and mixing blades 5 fixedly connected to the bottom of the square rod 4; an adjustment assembly 6 is provided on the top of the mixing tank 1, the adjustment assembly 6 including a drive gear 601 mounted on the surface of the rotating shaft 3, a gear ring 602 meshing with one side of the drive gear 601, a slider 603 mounted on the top of the square rod 4, and a protruding plate 604 slidably connected to the top of the slider 603. The mixing assembly 6 is used to adjust the mixing... The height of blade 5 is adjustable; a filter assembly 7 is provided on one side of the mixing tank 1. The filter assembly 7 includes a support cylinder 701 provided on one side of the mixing tank 1 and a filter cylinder 702 movably connected inside the support cylinder 701. The filter assembly 7 filters the adsorbed and filtered impurities; a drive assembly 8 is provided on one side of the mixing tank 1. The drive assembly 8 includes a drive motor 801 provided at the bottom of the mixing tank 1, a drive rod 802 installed at the output end of the drive motor 801, and a rotating rod 803 installed inside the rotating disk 2. The drive assembly 8 provides driving force to the filter assembly 7 and the adjustment assembly 6.

[0034] Specifically: The mixing tank 1 is used to contain and treat aquaculture wastewater. The rotating disk 2, which is movably connected to the top of the tank, provides a stable rotating platform for the entire mixing system, ensuring smooth mixing. The rotating shaft 3, which is movably connected inside the rotating disk 2, transmits power, transferring the rotational force of the drive component 8 to the mixing system. The square rod 4, which is slidably connected inside the rotating shaft 3, not only ensures the transmission of rotational force but also allows axial movement, providing height adjustment for the mixing blades 5. The mixing blades 5, which are fixedly connected to the bottom of the square rod 4, are the part that directly contacts the wastewater and can generate strong eddies, ensuring that the chemicals and wastewater are fully mixed. The engagement between the drive gear 601 and the surface of the rotating shaft 3 changes the direction of power transmission, converting horizontal rotation into vertical adjustment force. The gear ring 602, which meshes with one side of the drive gear 601, is fixed to the inner wall of the mixing tank 1. Through its meshing relationship with the drive gear 601, the mixing blades 5 are rotated. The sliding connection between the slider 603, which is fixedly connected to the top of the square rod 4, and the convex plate 604 constitutes the height adjustment actuator. The convex profile design at the bottom of the convex plate 604 can simulate the lifting trajectory and speed of the mixing blades 5.

[0035] Example 2: Please refer to Figures 1-8Based on embodiment 1, the drive assembly 8 further includes a first bevel gear 804 mounted on the surface of the drive rod 802 and a second bevel gear 805 mounted on the bottom of the rotating rod 803. The first bevel gear 804 and the second bevel gear 805 mesh with each other. A first spring 9 is sleeved on the surface of the square rod 4. One end of the first spring 9 is fixedly connected to the rotating shaft 3, and the other end of the drive rod 802 is fixedly connected to the filter cylinder 702. A sewage inlet pipe 10 is connected to one side of the mixing tank 1. The surface of the toothed ring 602 is fixedly connected to the inner wall of the mixing tank 1. A sewage outlet pipe 11 is connected to one side of the mixing tank 1. A solenoid valve 12 is sleeved on the surface of the sewage outlet pipe 11. The other end of the sewage outlet pipe 11 is connected to the support cylinder 701. A cam 13 is fixedly connected to the surface of the rotating rod 803. A push plate 14 is slidably connected to one side of the cam 13. A cleaning brush plate 15 is fixedly connected to the other side of the push plate 14. The other end of the cleaning brush plate 15 extends into the interior of the support cylinder 701.

[0036] Specifically: The filter assembly 7 installed on one side of the mixing tank 1 is the second stage of wastewater treatment. The support cylinder 701 serves as the support structure for the filter assembly 7, and the filter cylinder 702 inside it is movably connected to achieve secondary filtration of impurities after adsorption filtration. The filter cylinder 702 can effectively intercept pollutants of different particle sizes while maintaining smooth water flow. The drive motor 801 at the bottom of the mixing tank 1 serves as the power source, and the drive rod 802 connected to its output end transmits power to the entire system. The rotating rod 803 inside the rotating disk 2 realizes the transmission of power to the rotating disk 2, ensuring the stable operation of the mixing system. The drive assembly 8 also includes a first bevel gear 80 on the surface of the drive rod 802. The second bevel gear 805 at the bottom of the rotating rod 803 and the first bevel gear 804 achieves a 90-degree change in the power transmission direction, converting horizontal rotation into vertical rotation, making the equipment structure more compact. The precise meshing of the first bevel gear 804 and the second bevel gear 805 ensures efficient and stable power transmission. One end of the first spring 9 sleeved on the surface of the square rod 4 is fixedly connected to the rotating shaft 3. This design can automatically reset the mixing blade 5 after it has finished descending and stirring, realizing the periodic up and down movement of the mixing blade 5. The design of the other end of the drive rod 802 being fixedly connected to the filter cylinder 702 enables a single power source to drive both the stirring system and the filtration system simultaneously, improving energy utilization efficiency.

[0037] Example 3: Please refer to Figures 1-8Based on Embodiments 1 and 2, a second spring 16 is fitted on the surface of the cleaning brush plate 15. One end of the second spring 16 is fixedly connected to the push plate 14. A water storage tank 17 is fixedly connected to one side of the support cylinder 701. A pressurized water pump 18 is connected to one side of the water storage tank 17. A water spray pipe 19 is connected to the other end of the pressurized water pump 18. The other end of the water spray pipe 19 extends into the filter cylinder 702 and is connected to a nozzle 20. A support shell 21 is fixedly connected to the bottom of the support cylinder 701. A metal filter screen 22 is fixedly connected inside the support shell 21. A sedimentation tank 23 is fixedly connected to one side of the support shell 21. A bracket 24 is fixedly connected to one side of the drive motor 801. The top of the bracket 24 is fixedly connected to the mixing tank 1.

[0038] Specifically: The inlet pipe 10 connected to one side of the mixing tank 1 is the channel for sewage input. Its diameter and angle design ensure that the sewage can enter the mixing tank 1 smoothly without generating eddies. The fixed connection between the surface of the toothed ring 602 and the inner wall of the mixing tank 1 ensures the stability of the toothed ring 602 under long-term high-speed operation. The drain pipe 11 connected to one side of the mixing tank 1 introduces the pre-treated sewage into the filtration system. The solenoid valve 12 sleeved on its surface realizes precise control of the sewage discharge process. The cam 13 fixedly connected to the surface of the rotating rod 803 and the sliding connection between the cam 13 and the push plate 14 constitute the drive mechanism of the filter cartridge 702 cleaning system. The cleaning brush plate 15 fixedly connected to the other side of the push plate 14 penetrates into the support cylinder 701. Its special material design can effectively remove impurities from the surface of the filter cartridge 702. The second spring 16, which is fitted on the surface of the cleaning brush 15, is fixedly connected to the push plate 14 at one end, ensuring continuous contact pressure between the cleaning brush 15 and the surface of the filter cartridge 702, thus improving the cleaning effect. The water storage tank 17, which is fixedly connected to one side of the support cylinder 701, is used to store cleaning water. The pressurized water pump 18 connected to one side of the support cylinder 701 provides high-pressure water flow. The nozzle 20, which extends to the inside of the filter cartridge 702 at the other end of the spray pipe 19 and is connected to the filter cartridge 702, is designed to generate a rotating water curtain to achieve comprehensive cleaning of the filter cartridge 702. The support shell 21, which is fixedly connected to the bottom of the support cylinder 701, provides stable support for the entire filtration system. The sedimentation tank 23, which is fixedly connected to one side of the support shell 21, provides space for the treated water to settle and ensure that the effluent quality meets the standards.

[0039] The working principle of this invention is as follows: Workers transport the wastewater to be treated through the inlet pipe 10 into the mixing tank 1. Then, the flocculant required for filtration is mixed in a specific ratio and discharged into the mixing tank 1. An external controller starts the drive motor 801. The drive motor 801, in conjunction with the drive rod 802, drives the first bevel gear 804 to rotate. The first bevel gear 804, in conjunction with the second bevel gear 805, drives the rotating rod 803 to rotate. The rotating rod 803, in conjunction with the rotating disk 2, drives the rotating shaft 3 to rotate. When the rotating shaft 3 rotates, it drives the drive gear 601 to rotate. The drive gear 601 meshes with the gear ring 602, and the gear ring 602 drives the two sets of drive gears 601 to rotate synchronously. The drive gear 601, in conjunction with the rotating shaft 3, drives the square rod 4 to rotate. The square rod 4 drives the mixing blades 5 to rotate, agitating the wastewater and ensuring thorough mixing of the wastewater and flocculant.

[0040] While the square rod 4 rotates, it drives the slider 603 to contact the convex plate 604. The convex plate 604 can push the slider 603 and the square rod 4 to move downward. When the square rod 4 moves, it slides inside the rotating shaft 3 and continues to rotate, thereby adjusting the mixing height of the mixing blade 5, increasing the mixing range, and improving the wastewater treatment efficiency.

[0041] After initial adsorption and filtration, the wastewater can be discharged into the mixing tank 1 through the drain pipe 11. Then, the wastewater is filtered through the filter cartridge 702. The filtered wastewater is discharged into the sedimentation tank 23 for sedimentation filtration. While the drive rod 802 rotates, it also drives the filter cartridge 702 to rotate. When the filter cartridge 702 rotates, the position of the cleaning brush plate 15 remains unchanged. The cleaning brush plate 15 can be used to clean the impurities on the surface of the filter cartridge 702. While the rotating rod 803 rotates, it can push the push plate 14 to move. The push plate 14 drives the cleaning brush plate 15 to move and reciprocate to clean the surface of the filter cartridge 702, which can further improve the cleaning effect, make the filter cartridge 702 reusable, and improve the filtration effect of wastewater.

[0042] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
