Description

Technical Field

[0001] This utility model relates to the field of aquaculture cage technology, specifically a fish farming cage fish manure collection and treatment device. Background Technology

[0002] Fish farming cages are large-scale aquaculture facilities set up in water bodies, consisting mainly of netting, frames, and fixing devices. The netting creates a closed or semi-closed aquaculture space, the frame supports the netting to maintain its shape, and the fixing devices (anchors, cables, etc.) secure the cages to the designated water area, allowing fish to grow in a concentrated natural aquatic environment while facilitating feeding, management, and harvesting. Utility model patent CN223231865U discloses a fish manure collection and treatment device for aquaculture cages, including an aquaculture cage body. A collection mechanism is fixedly connected to the top of the aquaculture cage body, and a filter mechanism is snapped into the inner side of the collection mechanism. The aquaculture cage body provides a suitable growth environment for fish. Its connection with the collection mechanism and the filter mechanism allows fish manure to be collected and treated in a timely manner, keeping the aquaculture water clean and conducive to the healthy growth of fish. A float ensures that the collection mechanism floats stably on the water surface, facilitating connection and operation with the aquaculture cage body. When the servo motor receives a signal from the microcontroller, it can accurately drive the turntable to rotate, realizing the automatic switching of the filter tank, improving the efficiency of fish manure collection and treatment, reducing manual intervention, and providing an installation position for the filter tank. By rotating, different filter tanks can be quickly switched.

[0003] While this device utilizes a collection mechanism, a filtration mechanism, and a filter tank, among other components, to collect fish waste through adsorption by the collection mechanism and filtration by the filter, thus improving waste treatment efficiency, the waste from aquaculture often mixes with oil and adheres to the inner wall of the aquaculture net cage, leading to net blockage. Furthermore, heavier fish waste tends to settle due to its weight, hindering rapid collection and significantly reducing the overall efficiency of waste collection. Therefore, there is a need to develop a fish waste collection and treatment device for aquaculture net cages that avoids net blockage and improves collection and treatment efficiency. Utility Model Content

[0004] To address the above-mentioned technical problems, this utility model provides a fish manure collection and treatment device for fish farming cages that avoids net clogging and improves collection and treatment efficiency, thereby solving the problems of net clogging and poor treatment effect in existing collection and treatment devices.

[0005] To solve the above-mentioned technical problems, the present invention provides a fish manure collection and treatment device for fish farming cages, comprising a treatment chamber and a collection assembly. The outer surface of the treatment chamber is provided with a water inlet trough. The collection assembly includes an equipment chamber fixedly connected to the bottom of the treatment chamber, a circulation pump fixedly connected to the bottom of the equipment chamber, a circulation pipe fixedly connected to the output end of the circulation pump, a collection box fixedly connected to the top of the treatment chamber, an input end of the collection box fixedly connected to the end of the circulation pipe, an adsorption plate and an activated carbon plate respectively snapped into the inner wall of the collection box, and a drive assembly and an aeration assembly provided at the top of the treatment chamber.

[0006] Furthermore, the drive assembly includes a drive motor fixedly connected to the top of the processing chamber, the output end of the drive motor being coaxially driven by a drive shaft via a coupling sleeve, and the end of the drive shaft being fixedly connected to a limit plate.

[0007] Furthermore, a scraper is fixedly connected to the outer wall of the drive shaft. There are multiple scrapers, which are slidably connected to the inner wall of the processing chamber. A through groove is formed on the outer surface of the scraper.

[0008] Furthermore, the aeration assembly includes an air pump fixedly connected to the top of the treatment chamber, an aeration pipe fixedly connected to the output end of the air pump, and the outer wall of the aeration pipe fixedly connected to the outer wall of the treatment chamber through a limiting ring.

[0009] Furthermore, an inlet ring is fixedly connected to the input end of the circulating pump, and the end of the aeration pipe is connected to the inlet ring.

[0010] Furthermore, a mounting base is fixedly connected to the outer wall of the processing chamber, and the mounting base has a mounting groove.

[0011] Furthermore, a filter screen is snapped onto the inner wall of the equipment compartment, and filter grooves are formed on the filter screen.

[0012] This utility model has the following advantages compared with the prior art:

[0013] This invention, through the design of the collection components, enables the coordinated operation of various parts during the fish waste collection process. Air is continuously introduced into the water via aeration pipes, rapidly dispersing and agitating the suspended fish waste particles. This allows for better adsorption by the circulating pump, improving water purification. Furthermore, the operation of the drive motor causes multiple scrapers to continuously scrape the inner wall of the treatment chamber, preventing the outer mesh from becoming clogged with fish waste and further enhancing the fish waste collection efficiency.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] like Figure 1-4 The device for collecting and treating fish manure from fish farming cages shown includes a treatment chamber 1 and a collection assembly. The outer surface of the treatment chamber 1 is provided with a water inlet trough. The collection assembly includes an equipment chamber 2 installed at the bottom of the treatment chamber 1. A circulation pump 3 is installed at the bottom inner end of the equipment chamber 2. A circulation pipe 4 is installed at the output end of the circulation pump 3. A collection box 5 is fixedly connected to the top of the treatment chamber 1. The input end of the collection box 5 is fixedly connected to the end of the circulation pipe 4. An adsorption plate 6 and an activated carbon plate 7 are respectively snapped into the inner wall of the collection box 5. A drive assembly and an aeration assembly are provided at the top of the treatment chamber 1.

[0021] The drive assembly includes a drive motor 8 mounted on the top of the processing chamber 1. The output end of the drive motor 8 is coaxially driven by a drive shaft 9 through a coupling sleeve. The end of the drive shaft 9 is fixedly connected to a limit plate.

[0022] A scraper 10 is fixedly connected to the outer wall of the drive shaft 9. There are multiple scrapers 10, which are slidably connected to the inner wall of the processing chamber 1. A through groove is opened on the outer surface of the scraper 10.

[0023] Specifically, through the arrangement of the collection components, the water in the treatment chamber 1 is circulated by the continuously running circulation pump 3 during the fish farming process. This, along with the adsorption plates 6 and activated carbon plates 7 in the collection box 5, collects impurities and fish feces from the water, thereby improving the water filtration effect. A sealed door is provided on one side of the collection box 5. By opening the sealed door, the adsorption plates 6 and activated carbon plates 7 can be removed for cleaning or replacement to ensure the collection and treatment effect. The operation of the drive motor 8 drives the drive shaft 9 to rotate, thereby causing multiple scrapers 10 to rotate. This not only agitates the water so that suspended fish feces and impurities are sucked up by the circulation pump 3, but also scrapes the inner wall of the treatment chamber 1, thus preventing fish feces mixed with grease from clogging the water inlet tank on the outer surface of the treatment chamber 1, which would otherwise result in poor fish feces collection.

[0024] The aeration assembly includes an air pump 11 installed at the top of the treatment chamber 1. An aeration pipe 12 is fixedly connected to the output end of the air pump 11. The outer wall of the aeration pipe 12 is fixedly connected to the outer wall of the treatment chamber 1 through a limiting ring 13.

[0025] The input end of the circulating pump 3 is fixedly connected to the inlet ring 14, and the end of the aeration pipe 12 is fixedly connected to the inner wall of the inlet ring 14.

[0026] Specifically, by setting up the aeration components, compressed air can be continuously delivered into the interior of the inlet ring 14 through the aeration pipe 12 via the air pump 11. This results in a large amount of air being mixed in during the operation of the circulation pump 3, which not only prevents suspended solids in the water from settling but also delivers air into the water, allowing the suspended solids to tumble more effectively. The limiting ring 13 can stably connect the aeration pipe 12 to the outer wall of the treatment chamber 1, maintaining its stability during gas delivery.

[0027] The outer wall of the processing chamber 1 is fixedly connected to a mounting base 15, and the top of the mounting base 15 is provided with a mounting groove.

[0028] The inner wall of the equipment compartment 2 is fitted with a filter screen 16, and the outer surface of the filter screen 16 is provided with filter grooves.

[0029] Specifically, the mounting base 15 on the outer wall of the treatment chamber 1 allows for quick installation of the treatment chamber 1, thus maintaining its stability during use. The mounting slot at the top of the mounting base 15 allows for connection of the treatment chamber 1 to the external platform using bolts or other connecting tools. The filter screen 16, which is snapped onto the inner wall of the equipment chamber 2, separates the treatment chamber 1 from the equipment chamber 2, allowing fish waste to be collected through multiple filter tanks, which in turn enables the circulating pump 3 to quickly adsorb the fish waste.

[0030] The working principle of this embodiment is as follows:

[0031] When the equipment is installed in the aquaculture area and fish waste needs to be collected and treated, the circulation pump 3 is started. The circulation pump 3 sucks up the suspended impurities and fish waste in the water and transports them to the collection tank 5 through the circulation pipe 4. The sewage entering the collection tank 5 passes through the adsorption plate 6 and the activated carbon plate 7 to collect the impurities and fish waste in the water. At the same time, the drive motor 8 is started and drives the drive shaft 9 and scraper 10 to rotate. The scraper 10 can agitate the water so that the suspended fish waste and impurities in the water are sucked up by the circulation pump 3. At the same time, it rotates and scrapes the inner wall of the treatment chamber 1, thereby preventing fish waste mixed with oil from clogging the water inlet tank on the outer surface of the treatment chamber 1. At the same time, the air pump 11 is started and continuously delivers air into the interior of the water inlet ring 14 through the aeration pipe 12. Thus, a large amount of air is mixed in during the operation of the circulation pump 3. This can prevent the suspended solids in the water from settling and can also deliver air into the water, so that the suspended solids can be better turbulent and improve the collection and treatment effect.
