Description

Technical Field

[0001] This utility model belongs to the field of algae treatment technology, specifically relating to an algae treatment device for aquaculture water. Background Technology

[0002] In aquaculture environments, the presence of algae can cause numerous adverse effects. Some algae species have the characteristic of rapid reproduction, and when environmental conditions are suitable, they will proliferate in large quantities, forming algal blooms. Algal blooms first obscure the water surface, hindering sunlight penetration. This prevents phytoplankton and aquatic plants in the middle and lower layers of the water from photosynthesizing properly due to insufficient light, leading to a decrease in dissolved oxygen levels in the water. This affects the respiration of aquaculture organisms and, in severe cases, can cause them to die from oxygen deprivation. Therefore, regular algae control is necessary.

[0003] A related technology (publication number CN114656084A) discloses a biological treatment device for removing algae from aquaculture water, including a box with an open upper side. A discharge pipe is fixedly connected to the bottom of one side of the box, a support plate is fixedly connected to the upper side of the box, and a water pumping pipe is fixedly connected to the support plate. A buffer pipe is fixedly connected to one end of the water pumping pipe extending above the box. The buffer pipe has closed ends and a discharge slot at its bottom. A circular shaft is coaxially rotatably connected inside the buffer pipe. Multiple baffles are fixedly connected to the outer annular array of the circular shaft, and the baffles are slidably connected to the inner wall of the buffer pipe. A fan-shaped hole is provided on the upper side of the buffer pipe. A horizontal plate is fixedly connected to the upper side of the support plate, and an ultraviolet lamp is fixedly connected to the bottom of the horizontal plate. The ultraviolet lamp is positioned corresponding to the fan-shaped hole. A filtration and drying device is installed on the inner wall of the box to filter and dry algae. This invention sterilizes the water by irradiating it with ultraviolet light. The water is flushed into a conical hopper and vibrated to ensure sufficient ultraviolet irradiation, thus improving sterilization efficiency.

[0004] However, when treating algae in existing aquaculture water bodies, manual harvesting of algae is required, which takes a lot of time and effort. Furthermore, manual harvesting of algae can easily leave dead spots. Algae remaining in these dead spots can continue to reproduce and multiply, making it difficult to substantially improve the ecological quality of the aquaculture water bodies. Utility Model Content

[0005] Existing technologies for treating algae in aquaculture waters require manual harvesting, which is time-consuming and labor-intensive. Furthermore, manual harvesting often leaves untreated areas where algae can proliferate, hindering any substantial improvement in the ecological quality of the aquaculture water. This invention provides an algae treatment device for aquaculture water. This device automatically treats algae uniformly on a first screen, scraping it off to a baffle for discharge. No manual operation is required. The scraper rotates circumferentially along the upper surface of the first screen, ensuring comprehensive algae removal and avoiding the blind spots left by manual harvesting. This prevents the problem of untreated algae hindering the improvement of the aquaculture water's ecological quality. The specific technical solution is as follows:

The first treatment mechanism is located above the treatment tank and is used to remove large amounts of algae in the water. The second treatment mechanism is located inside the treatment tank and is used to remove small amounts of algae in the water.

[0007] The second processing mechanism includes a support arm installed on the side wall of the processing box, the end of the support arm extending above the processing box, a first motor installed on the support arm, a drive shaft connected to the output end of the first motor, a housing fixedly installed at the bottom end of the drive shaft, an extension seat fixedly installed on the side wall of the housing, a scraper fixedly installed at the bottom end of the extension seat, a first screen installed inside the processing box, and the scraper moving counterclockwise circumferentially along the upper surface of the first screen.

[0008] In the above technical solution, a pushing component is provided at the extension seat;

[0009] The pushing component includes a groove formed in the side wall of the extension seat, a lead screw rotatably connected in the groove, a second motor installed in the housing, the output end of the second motor connected to the lead screw, a moving block threaded on the lead screw, the moving block slidably embedded in the groove in the side wall of the extension seat, a push plate fixedly installed at the bottom end of the moving block, the side wall of the push plate being vertical and conforming to the side wall of the scraper.

[0010] In the above technical solution, a trigger component is provided at the extension seat;

[0011] The triggering component includes a partition plate mounted on the extension base, a mounting rod mounted on the support arm, and a photoelectric sensor mounted on the mounting rod. The position of the photoelectric sensor corresponds to the position of the partition plate.

[0012] In the above technical solution, a groove is provided on the side wall of the processing box, a baffle is slidably inserted into the groove of the side wall of the processing box, a support frame is fixedly installed on the processing box, a cylinder is installed on the support frame, and the output end of the cylinder is connected to the upper surface of the baffle.

[0013] In the above technical solution, the first processing mechanism includes a mounting arm fixedly installed on the processing box, the mounting arm is fixedly connected to a liquid inlet funnel, an inner filter funnel is provided inside the liquid inlet funnel, and a second screen is installed at the bottom of the inner filter funnel.

[0014] In the above technical solution, the inner filter funnel and the liquid inlet funnel are connected by a limiting component;

[0015] The limiting component includes a limiting pin fixedly installed at the top edge of the side wall of the liquid inlet funnel, and a positioning seat fixedly installed at the top edge of the side wall of the liquid inlet funnel. The positioning seat has a positioning groove, and the limiting pin is rotatably embedded in the inner cavity of the positioning groove in the horizontal direction.

[0016] In the above technical solution, the hole spacing of the second screen is larger than that of the first screen.

[0017] In the above technical solution, the controller is electrically connected to the first motor, the second motor, the photoelectric sensor, and the cylinder, respectively.

[0018] Compared with existing technologies, the beneficial effects of this novel algae treatment device for aquaculture water are as follows:

[0019] I. When treating algae in existing aquaculture water bodies, manual algae harvesting is required, which is time-consuming and labor-intensive. Furthermore, manual harvesting often leaves dead spots where algae can continue to multiply, hindering substantial improvement in the ecological quality of the aquaculture water. This invention separates algae from the water and automatically processes them on a first screen, scraping them uniformly to the baffle and discharging them outwards. No manual operation is required, and the scraper rotates circumferentially along the upper surface of the first screen, ensuring comprehensive algae removal and avoiding the dead spots associated with manual harvesting. This prevents the problem of unremoved algae hindering substantial improvement in the ecological quality of the aquaculture water.

[0020] II. This utility model uses a scraper that rotates circumferentially along the upper surface of the first screen to scrape the algae precipitated on the upper surface of the first screen to the baffle. When the separator rotates to the corresponding photoelectric sensor, the baffle can be automatically opened upward and the push plate can be controlled to move, so that the algae scraped by the scraper can be automatically discharged through the opened baffle. This can automatically scrape and discharge algae into the treatment box, with a high degree of automation, saving the time and effort of manual multi-step operation.

[0021] Third, this utility model also has a pretreatment function for large algae. By transporting water containing large algae to the second screen in the inner filter chamber, the large algae can be separated with the help of the second screen, ensuring that the water entering the treatment chamber for subsequent treatment contains only small algae, reducing the pressure of algae treatment in the treatment chamber. Furthermore, large and small algae are treated separately, which is more targeted and results in better algae removal.

[0022] Fourth, in this utility model, the inner filter funnel is easy and quick to disassemble and install at the liquid inlet funnel, which makes it easier to pour out the large amount of algae precipitated at the second screen.

[0023] In summary, this invention can automatically process algae uniformly on the first screen, scraping the algae to the baffle and discharging them outwards without manual operation. The scraper rotates circumferentially along the upper surface of the first screen, ensuring comprehensive algae removal and avoiding dead spots caused by manual algae removal. This prevents the problem of ineffective algae accumulation hindering the improvement of the aquaculture water's ecological quality. Furthermore, the second screen allows for the separation of large quantities of algae, ensuring that the water entering the treatment chamber contains only small amounts of algae, reducing the pressure on the treatment chamber. The separate treatment of large and small algae allows for more targeted and effective algae removal. Attached Figure Description

[0031] The following is a combination of specific implementation cases and attached Figures 1 to 6 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0032] See Figures 1 to 6 As shown, the aquaculture water algae treatment device includes a treatment tank 1, a controller 2 installed on the side wall of the treatment tank 1, a first treatment mechanism and a second treatment mechanism installed in the treatment tank 1. The first treatment mechanism is located above the treatment tank 1 and is used to remove large algae in the water. The second treatment mechanism is located inside the treatment tank 1 and is used to remove small algae in the water. The second treatment mechanism includes a support arm 3 installed on the side wall of the treatment tank 1. The end of the support arm 3 extends to the top of the treatment tank 1. A first motor 4 is installed on the support arm 3. The output end of the first motor 4 is connected to a drive shaft 5. A housing 6 is fixedly installed at the bottom end of the drive shaft 5. An extension seat 8 is fixedly installed on the side wall of the housing 6. A scraper 10 is fixedly installed at the bottom end of the extension seat 8. A first screen 16 is installed inside the treatment tank 1. The scraper 10 moves counterclockwise circumferentially along the upper surface of the first screen 16.

[0033] The controller 2 controls the first motor 4 to turn on, and the first motor 4 causes the drive shaft 5, housing 6, extension seat 8 and scraper 10 to rotate counterclockwise in a circumferential direction. The opened scraper 10 moves along the upper surface of the first screen 16 to uniformly scrape off the algae that have precipitated on the first screen 16.

[0034] In addition, see Figure 2 and Figure 3As shown, a pushing component is provided at the extension seat 8; the pushing component includes a groove formed in the side wall of the extension seat 8, a lead screw 9 is rotatably connected in the groove of the side wall of the extension seat 8, a second motor 7 is installed in the housing 6, the output end of the second motor 7 is connected to the lead screw 9, a moving block 11 is threaded on the lead screw 9, the moving block 11 is slidably embedded in the groove of the side wall of the extension seat 8, a push plate 12 is fixedly installed at the bottom end of the moving block 11, the side wall of the push plate 12 is vertical and fits against the side wall of the scraper 10; when the second motor 7 is turned on, the lead screw 9 rotates, causing the moving block 11 to drive the push plate 12 to move towards the outer edge of the processing box 1, thereby further pushing the algae scraped by the counterclockwise rotating scraper 10 to the outer edge of the processing box 1; a triggering component is provided at the extension seat 8; the triggering component includes a partition plate 13 installed on the extension seat 8, an installation rod 14 installed at the support arm 3, and an installation rod 14 installed at the installation rod 14. A photoelectric sensor 15 is provided, and its position corresponds to the position of the separator 13. A groove is provided on the side wall of the processing box 1, and a baffle 20 is slidably inserted into the groove. A support frame 18 is fixedly installed on the processing box 1, and a cylinder 19 is installed on the support frame 18. The output end of the cylinder 19 is connected to the upper surface of the baffle 20. When the scraper 10 moves, it causes the separator 13 at its top to move to the photoelectric sensor 15. At this time, the photoelectric sensor 15 transmits a signal to the controller 2. The controller 2 controls the second motor 7 and the cylinder 19 to open. The opened cylinder 19 moves the baffle 20 upward to the groove that is detached from the side wall of the processing box 1, thus opening the baffle 20. With the pusher 12 moving towards the edge of the processing box 1, the algae scraped by the scraper 10 can be pushed out of the inner cavity of the processing box 1 through the opened groove, so that the algae can be automatically discharged to the outside.

[0035] Main references Figure 1 , Figure 4 and Figure 5 As shown, the first processing mechanism includes an installation arm 21 fixedly installed on the processing box 1. The installation arm 21 is fixedly connected to an inlet funnel 22. An inner filter 24 is provided inside the inlet funnel 22. A second screen 25 is installed at the bottom of the inner filter 24. The inner filter 24 and the inlet funnel 22 are connected by a limiting component. The limiting component includes a limiting pin 23 fixedly installed at the top edge of the side wall of the inlet funnel 22, and a positioning seat 26 fixedly installed at the top edge of the side wall of the inlet funnel 22. A positioning groove 27 is provided at the positioning seat 26. The limiting pin 23 rotates horizontally and is embedded in the cavity of the positioning groove 27. After the equipment is used, the positioning seat 26 is rotated clockwise to make the limiting pin 23 disengage from the cavity of the positioning groove 27. This allows the inner filter 24 to be lifted upwards and disengaged from the inlet funnel 22, thus cleaning the large amount of algae precipitated in the inner filter 24.

[0036] Specifically, the aperture spacing of the second screen 25 is larger than that of the first screen 16, thereby enabling the removal of large quantities of algae from the water body through the second screen 25 and the removal of small quantities of algae from the water body through the first screen 16.

[0037] In addition, the controller 2 is electrically connected to the first motor 4, the second motor 7, the photoelectric sensor 15, and the cylinder 19 respectively. The controller 2 can control the above components to start and stop at corresponding times, so that the above components can complete a series of operations for the removal of algae by the device. It will not be described or limited in detail here, as long as it meets the requirements of this application.

[0038] It is worth noting that in this application, the controller 2 is a commonly used controller on the market, which can control the start-stop and switching timing of the electrically connected components. It only needs to meet the usage requirements, and its model is not limited here. The cylinder 19 used is a commonly used self-locking cylinder on the market, whose output end can stay at any position and lock. The first motor 4 and the second motor 7 are commonly used self-locking motors with lockable output ends on the market. When they stop, their output ends can self-lock and will not rotate under external force. Furthermore, the first motor 4 is a commonly used forward and reverse motor on the market, whose output end can rotate in either the forward or reverse direction according to usage requirements. The actuator only needs to meet the above-mentioned usage requirements; the lead screw 9 is a self-locking lead screw available on the market, which can self-lock when it stops rotating and will not be affected by external forces to rotate; the photoelectric sensor 15 is a commonly used photoelectric sensor on the market, consisting of a transmitter and a receiver. The transmitter is a light-emitting diode (LED) that can emit a beam of light, and the receiver is a photosensitive element that can receive the light emitted by the transmitter. When there is no object blocking it, the light emitted by the transmitter can be received normally by the receiver, and at this time, the second motor 7 and cylinder 19 will not be triggered to open; the model of the above-mentioned existing components will not be limited or described in detail here.

[0039] The working principle of the algae treatment device for aquaculture water in this embodiment is as follows:

[0040] Water containing algae is pumped into the inner cavity of the inlet funnel 22. Under the action of the second screen 25 set in the limiting pin 23, large amounts of algae in the water can be separated. The mixture of small amounts of algae and water passes through the second screen 25 and enters the first screen 16 in the inner cavity of the treatment tank 1 for further treatment. The small amounts of algae entering the first screen 16 are separated on the upper surface of the first screen 16. The treated water enters the inner cavity of the treatment tank 1 below the first screen 16 and is then discharged to the next process through the open drain outlet 17, realizing the return of water after algae treatment.

[0041] After the equipment is used, the controller 2 controls the first motor 4 to start. The first motor 4 causes the drive shaft 5, housing 6, extension seat 8, and scraper 10 to rotate counterclockwise in a circumferential direction. The opened scraper 10 moves along the upper surface of the first screen 16, uniformly scraping away the algae that have precipitated on the first screen 16. As the scraper 10 moves, the separator 13 at its top moves to the photoelectric sensor 15. At this time, the photoelectric sensor 15 transmits a signal to the controller 2. The controller 2 controls the second motor 7 and cylinder 19 to start. The opened second motor 7 causes the drive shaft 5, housing 6, extension seat 8, and scraper 10 to rotate counterclockwise in a circumferential direction. Rotating the lead screw 9 causes the moving block 11 to drive the push plate 12 to move towards the outer edge of the processing box 1. This pushes the algae scraped by the counterclockwise rotating scraper 10 further to the outer edge of the processing box 1. At the same time, the opened cylinder 19 moves the baffle 20 upward to the trough that is detached from the side wall of the processing box 1, thus opening the baffle 20. With the push plate 12 moving towards the edge of the processing box 1, the algae scraped by the scraper 10 can be pushed out of the inner cavity of the processing box 1 through the opened trough of the processing box 1, so that the algae can be automatically discharged to the outside.

[0042] After the equipment is used up, rotate the positioning seat 26 clockwise to make the limiting pin 23 disengage from the inner cavity of the positioning groove 27, thereby lifting it upward away from the inner filter 24 and making it detach from the liquid inlet funnel 22, so that the large amount of algae precipitated in the inner filter 24 can be cleaned.

[0043] This invention enables automatic processing of algae on the first screen 16, scraping the algae to the baffle 20 and discharging them outwards without manual operation. The scraper 10 rotates circumferentially along the upper surface of the first screen 16, achieving comprehensive removal of algae and avoiding dead spots caused by manual algae removal. This prevents the problem of ineffective algae removal from hindering the improvement of the ecological quality of the aquaculture water. In addition, the second screen 25 enables the separation of large quantities of algae, ensuring that the water entering the treatment chamber 1 contains only small quantities of algae, reducing the pressure on the treatment chamber 1. Furthermore, the separate treatment of large and small quantities of algae makes the process more targeted and results in better algae removal.

[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
