Description

Technical Field

[0001] This utility model relates to the technical field of aquaculture filtration equipment, specifically a circulating water control filtration device for aquaculture. Background Technology

[0002] In the field of modern factory-style aquaculture, recirculating aquaculture systems have become the mainstream model in the industry due to their high efficiency, water conservation, environmental friendliness, and controllability. This system effectively removes pollutants such as suspended solids, ammonia nitrogen, bacteria, dissolved organic matter, and undigested feed from the aquaculture water through circulation and filtration, creating a relatively stable living environment for the farmed organisms.

[0003] However, in actual operation, the continuous accumulation of organic matter such as feed residue and aquaculture waste poses a severe challenge to the circulating water filtration process. Industry statistics show that in high-density aquaculture scenarios, conventional filters become clogged with pollutants every 7-10 days on average, resulting in a filtration efficiency decrease of over 30%. If not addressed promptly, this not only deteriorates water quality, leading to excessive concentrations of harmful substances such as ammonia nitrogen and nitrite, but may also trigger stress responses in aquaculture organisms, increasing the risk of disease outbreaks. Currently, solving the filter clogging problem mainly relies on manual, periodic disassembly, cleaning, or replacement of the filters. This not only consumes significant manpower and time costs, but frequent equipment maintenance can also disrupt the stable operation of the aquaculture system, significantly increasing the operational burden on farmers and hindering the large-scale and intelligent development of factory-style aquaculture.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] The following description is intended to disclose the present invention and to enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0028] Example 1:

[0029] Please see Figures 1-6 The diagram shows a circulating water control and filtration device for aquaculture, including a base 1. An aquaculture pond 2 is located on one side of the base 1, and its inner wall is treated with a special coating to effectively prevent water corrosion of the pond wall and reduce frictional resistance between the water and the pond wall. It also includes a filter box 3 mounted on the base 1 via support legs. A disinfection lamp is installed on the top of the inner wall of the filter box 3, which disinfects the water using ultraviolet light. The filter box 3 contains a flat filter screen 21 and an inclined filter screen 22, which are made of multi-layer composite filter material for dual filtration of impurities. The outer surface of the filter box 3... The filter box 3 is equipped with an installation box 4. A disinfection box 5 is installed on top of the filter box 3. The disinfection box 5 stores disinfectant, which disinfects the water while ensuring the water is suitable for aquaculture. A metering valve 18 is installed at the bottom of the disinfection box 5, extending through and into the interior of the filter box 3 to facilitate the periodic metering of disinfectant. Impurity boxes 6 are symmetrically installed on the outside of the filter box 3 to store filtered impurities. An external drawer allows for periodic cleaning of the impurities. A connection is provided on the filter box 3 above the flat filter screen 21 and the inclined filter screen 22 to facilitate the filling of the filter box 3 with disinfectant. The inclined holes 32 on the filter box 3 are connected to the impurity box 6 at a 45-degree angle, precisely aligning with the internal space of the impurity box 6 to ensure that impurities can smoothly slide into the impurity box 6, thus facilitating cleaning by farmers. A circulation pump 33 is installed on the base 1. The input end of the circulation pump 33 is fixedly connected to and communicates with the breeding pond 2, and the output end of the circulation pump 33 extends through and into the interior of the filter box 3. A water pipe runs through the bottom of the filter box 3 and extends into the breeding pond 2. The turbid water in the breeding pond 2 is transported to the filter box 3 by the circulation pump 33. After double filtration, the water flows through the water pipe... The water flows back into the aquaculture pond 2, facilitating water circulation. The return water pipe can create a certain drop in height with the aquaculture pond, thereby increasing oxygen levels inside the pond and promoting aquatic product growth. Additionally, a cleaning component 7 is installed on the filter box 3 and mounting box 4 to clean the flat filter screen 21 and the inclined filter screen 22. Furthermore, an anti-clogging component 8 is installed below the cleaning component 7 to prevent the flat filter screen 21 and the inclined filter screen 22 from clogging. Finally, a stirring component 9 is installed below the anti-clogging component 8 to agitate the water containing disinfectant.

[0030] During operation, the circulation pump 33 starts, drawing turbid water from the aquaculture pond 2 into the filter box 3. The water first undergoes preliminary filtration through the inclined filter screen 22, where larger particles are intercepted. It then undergoes secondary fine filtration through the flat filter screen 21, further removing smaller particles. During filtration, impurities slide through the inclined holes 32 into the impurity box 6 under the impact of the water flow and their own gravity. After double filtration, the water enters the mixing stage after disinfectant is injected through the metering valve 18. Finally, the disinfected and thoroughly mixed water flows back to the aquaculture pond 2 through the return water pipe, completing a full water circulation and purification process.

[0031] Furthermore, the cleaning component 7 includes a motor 10 installed inside the mounting box 4. The output end of the motor 10 is fixedly connected to a drive wheel 11 via a coupling. A driven wheel 13 is rotatably connected inside the mounting box 4. A belt 12 is synchronously provided outside the drive wheel 11 and the driven wheel 13.

[0032] Furthermore, the output end of the motor 10 is fixedly connected to the lead screw 14 through the filter box 3 via a coupling. The other end of the lead screw 14 is rotatably connected to the side wall of the filter box 3. The lead screw 14 is connected to the slider 15 by external thread. A smooth rod 16 is installed above the lead screw 14. The smooth rod 16 is made of stainless steel and its surface is polished to facilitate the sliding connection between the slider 15 and the smooth rod 16.

[0033] Specifically: A connecting frame 17 is installed at the bottom of the slider 15, a scraper 19 is installed on the outside of the connecting frame 17, and a cleaning brush 20 is installed at the bottom of the connecting frame 17. The cleaning brush 20 is made of nylon. When the motor 10 starts, it drives the lead screw 14 to rotate through the coupling, thereby driving the slider 15 to slide along the smooth rod 16. At the same time, the connecting frame 17 can drive the scraper 19 to scrape off impurities on the surface of the flat filter screen 21 and clean fine impurities, thus making it easier to keep the flat filter screen 21 clean and tidy.

[0034] Example 2:

[0035] This embodiment provides a further explanation of Example 1, based on... Figures 3-6As shown, it is worth noting that the anti-clogging component 8 includes fixed blocks 23 symmetrically installed inside the filter box 3. Each fixed block 23 has a spring 24 installed on its top. The spring 24 is made of high-strength alloy spring steel and is fixedly connected to the inclined filter screen 22. The bottom of the inclined filter screen 22 is symmetrically equipped with protruding posts 25, which are made of stainless steel. The driven wheel 13 is coaxially fixedly connected to a rotating rod 26. The rotating rod 26 is symmetrically fixedly connected to a cam 27. The position of the cam 27 corresponds to the protruding post 25. When the motor 10 rotates, with the cooperation of the driving wheel 11, the driven wheel 13 and the belt 12, the rotating rod 26 is easily driven to rotate, thereby causing the cam 27 to indirectly hit the protruding post 25, thus preventing the inclined filter screen 22 from clogging.

[0036] Further reference Figure 3 - Figure 5 As shown, the stirring component 9 includes a connecting box 28 installed inside the filter box 3. A bevel gear 29 is rotatably connected inside the connecting box 28. The bevel gear 29 is fixedly installed outside the rotating rod 26. A helical gear 30 is meshed with the outside of the bevel gear 29. The helical gear 30 is rotatably connected to the connecting box 28. The helical gear 30 coaxially passes through the connecting box 28 and is fixedly connected to the stirring rod 31. Through the cooperation of the disinfection box 5 and the metering valve 18 at the top, it is convenient to disinfect the water in a metered manner. At the same time, through the structural linkage of the cleaning component 7 and the anti-clogging component 8, it is convenient to drive the stirring rod 31 to stir with the disinfected water, thereby keeping the water clean and tidy, which is conducive to the large-scale development of aquaculture.

[0037] The principle behind this solution is as follows:

[0038] First, when the motor 10 starts, it drives the lead screw 14 to rotate via the coupling. The rotation of the lead screw 14 is converted into the linear motion of the slider 15 along the guide rod 16. During the movement of the slider 15, the scraper 19 and the cleaning brush 20 move synchronously via the connecting frame 17. The scraper 19 first scrapes away larger impurities from the surface of the flat filter screen 21, and then the cleaning brush 20 performs a deep cleaning of the flat filter screen 21 to remove residual fine impurities.

[0039] Secondly, when the motor 10 rotates, it drives the rotating rod 26 to rotate through the transmission of the driving wheel 11, belt 12, and driven wheel 13, thereby causing the cam 27 to rotate accordingly. When the protruding part of the cam 27 contacts the protrusion 25, it generates an upward impact force on the protrusion 25, causing the inclined filter screen 22 to vibrate slightly. This vibration can effectively shake off the impurities clogging the mesh of the inclined filter screen 22, preventing the accumulation of impurities from clogging the filter screen. At the same time, the spring 24 plays a role in buffering and resetting when the inclined filter screen 22 is impacted and vibrated, ensuring that the inclined filter screen 22 can quickly return to its initial position after vibration and maintain normal filtration operation.

[0040] Finally, when the motor 10 drives the rotating rod 26 to rotate, the rotating rod 26 transmits power to the stirring rod 31 through the meshing transmission of the bevel gear 29 and the helical gear 30, causing the stirring rod 31 to rotate. During the rotation of the stirring rod 31, its blades drive the water to move, forming strong convection and eddies, which makes the disinfectant and the filtered water fully mixed.

[0041] It should be noted that the drive motor 10, the metering valve 18, the circulating pump 33, etc. are all equipped with power supplies, which are mature technologies in this field and have been fully disclosed, so they will not be repeated in the specification.

Furthermore, under the teachings of this utility model, modifications to these features and embodiments can be made to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
