Description

Technical Field

[0001] This utility model belongs to the field of aquaculture technology, specifically relating to a detachable centrifugal assembly for aquaculture. Background Technology

[0002] In existing fishery production, it is often necessary to separate solids and liquids in the water during aquaculture. During the aquaculture process, the aquaculture water contains solid impurities such as feed residue and excrement. If these solid impurities are not removed in time, they will affect and pollute the aquatic environment and even harm the health of the aquaculture organisms. For the removal of solid waste, the commonly used equipment is the centrifugal filter. The centrifugal filter uses the centrifugal force generated by high-speed rotation to make the liquid containing solid impurities throw the solid impurities to the inner wall of the filter under the action of centrifugal force. The purified liquid flows out through the filter screen, and the intercepted solid waste is discharged from the bottom of the filter screen under the action of centrifugal force. This can effectively separate solid waste and liquid in the aquaculture tailwater, quickly separate and remove pollutants in the aquaculture wastewater, and improve filtration efficiency. Centrifugal filters have been widely used in the field of aquaculture, which not only improves the aquaculture efficiency, but also helps environmental protection and sustainable use of resources. Nevertheless, existing centrifugal filters still have the following disadvantages: (1) High energy consumption: High-speed rotation requires high power drive: The working principle of the centrifugal filter relies on the centrifugal force generated by high-speed rotation to achieve solid-liquid separation. It needs to be equipped with a high-power motor to drive the rotating drum, which consumes a lot of energy. In some areas with tight energy supply or high electricity costs, this may increase the cost of aquaculture. (2) High energy consumption during continuous operation: In order to ensure the filtration effect and the continuity of water treatment, centrifugal filters need to run continuously for a long time, which will also consume a lot of electricity. (3) Many easily worn parts: The internal components of centrifugal filters, such as the rotating drum, bearings, and sealing rings, are easily worn during high-speed rotation and long-term use, and need to be replaced regularly, which increases the maintenance cost of the equipment. (4) Difficult to clean: Dirt and impurities easily accumulate inside the filter, which requires regular cleaning. However, due to its complex structure, the cleaning process is relatively cumbersome and requires a lot of time and manpower. For example, the internal space of the rotating drum of some centrifugal filters is narrow, making it difficult for cleaning tools to enter, resulting in incomplete cleaning. Utility Model Content

[0003] To address the aforementioned technical problems, this invention proposes a detachable centrifugal filter assembly for aquaculture. This assembly is detachable, movable, and highly compatible, allowing it to be placed in various application scenarios according to user needs. Pressurized aquaculture wastewater flows into the centrifugal filter at a 45-degree angle, creating a high-pressure jet that rotates the 316 stainless steel filter screen, generating centrifugal force to achieve solid-liquid separation. The filtered clean water then flows back to the aquaculture pond or biological treatment tank for the next treatment stage. This invention utilizes a detachable structure, allowing for easy disassembly of all components for thorough internal cleaning, effectively removing accumulated impurities and maintaining the filter's filtration efficiency and performance. Easily worn parts can be replaced individually without replacing the entire filter, reducing maintenance costs and equipment downtime.

[0004] The technical solution disclosed in this utility model is as follows:

[0005] A detachable centrifuge assembly for aquaculture includes a bearing housing, an inner bearing housing, two support frames, a filter screen, an upper support device, a lower support device, and a fixing component. The top of the fixing component is connected to the bearing housing, and the bottom is connected to the upper support device. The filter screen is detachably fixed between the upper and lower support devices, with an upper cylindrical shape and a lower conical shape. A wastewater pipe is connected to the bottom of the filter screen, which passes through the lower support device and can rotate within it. The inner bearing housing is annular, with two support frames connected to both sides. The fixing component passes through the inner bearing housing, and the bearing housing is engaged with it. The bearing housing, fixing component, filter screen, upper support device, and lower support device can rotate axially along the central axis of the centrifuge assembly. The filter screen is made of stainless steel, and the pore size of the filter screen is no greater than 38μm. It also includes a water inlet pipe connected to a pressurized water pump, positioned at a 45-degree angle to transport aquaculture wastewater into the centrifuge assembly.

[0006] Preferably, it also includes a flushing water pipe disposed along the conical bottom of the filter screen, and the flushing water pipe is provided with one or more nozzles.

[0007] Preferably, it also includes a processing container for placing the centrifugal assembly, with four fixing slots provided on the inner wall of the container, and the four ends of the two support frames are disposed on the fixing slots.

[0008] Compared with the prior art, the present invention has the following technical advantages:

[0009] (1) The centrifugal component in this utility model utilizes the pressurized aquaculture wastewater flowing into the inner side of the centrifugal filter at a 45-degree angle. The high-pressure column water flow drives the stainless steel 316 filter screen to rotate, generating centrifugal force. The liquid passes through the filter screen and enters the aquaculture pond or biochemical pond for the next treatment process. The solid sludge, because it contains water, is carried to the center of the filter screen by the centripetal force of the inward inclined side and discharged through the sewage pipe. In the whole process, there is no need to use a high-power motor to drive the rotating drum (with filter screen) to rotate. Only a pressurized water pump is needed, which saves energy and reduces the operating cost of the equipment.

[0010] (2) The centrifugal assembly in this utility model can be easily disassembled for comprehensive and thorough cleaning, which can effectively remove dirt, fish feces, uneaten bait and other impurities inside the filter assembly, maintain the filter's good filtration performance and extend the equipment's service life.

[0011] (3) The detachable design of this utility model makes it easier to replace easily worn parts, such as worn bearings and damaged filter screens. They can be disassembled and replaced individually without replacing the entire filter, thus reducing maintenance costs and equipment downtime. The centrifugal assembly can be cleaned and maintained regularly, and worn parts can be replaced in a timely manner to ensure that the filter always maintains high filtration efficiency and stable filtration effect.

[0012] (4) When the centrifuge components malfunction, the detachable structure allows technicians to disassemble the equipment and quickly locate the fault. For minor faults, timely on-site repairs can be carried out, reducing the time and cost of returning the equipment to the factory for repairs. This does not affect the normal operation of fishery production.

[0013] (5) When not in use, the various components of this utility model can be disassembled, occupying less space and facilitating storage. This advantage is particularly evident in fish farms or processing facilities with limited space. Furthermore, the disassembled filter components are small in size and light in weight, making them easy to handle and transport, thus reducing transportation costs and the risk of damage to the equipment during transportation.

[0018] The present invention will now be further described in conjunction with specific embodiments and accompanying drawings.

[0019] like Figs. 1-3 As shown, this utility model discloses a detachable centrifuge assembly for aquaculture, including a bearing seat 1, an inner bearing seat 2, two support frames 3, a filter screen 4, an upper support device 5, a lower support device 6, and a fixing member 7. The bearing seat 1, inner bearing seat 2, and fixing member 7 are preferably hollow cylindrical in shape. The top of the fixing member 7 is connected to the bearing seat 1, and the bottom is detachably connected to the upper support device 5. The filter screen 4 is detachably fixed between the upper support device 5 and the lower support device 7. The upper side of the filter screen 4 is cylindrical, the lower side is conical, and the bottom is connected to a sewage pipe 8. The sewage pipe 8 passes through the lower support device 7 and can rotate within it. The two support frames 3 are immovably connected to both sides of the inner bearing seat 2. The fixing member 7 passes through the inner bearing seat 2, and the bearing seat 1 is secured to the inner bearing seat 2. The bearing seat 1, fixing member 7, filter screen 4, upper support device 5, and lower support device 6 can rotate axially along the central axis of the centrifuge assembly. It also includes an inlet pipe 9, which is connected to a booster pump (not shown in the figure). The inlet pipe 9 is positioned at a 45-degree angle to transport the aquaculture wastewater to be separated into the centrifuge assembly.

[0020] The filter screen 4 in this invention is made of stainless steel, and the pore size on the filter screen 4 is no greater than 38μm.

[0021] To prevent dirt from clogging the sewage pipe or accumulating at the bottom of the filter screen 4, this invention also provides a flushing water pipe 10 at the conical bottom of the filter screen 4, with five nozzles 11 on the flushing water pipe 10. The flushing water pipe 10 is connected to a pressurized water pump.

[0022] The centrifugal component in this invention is movable and detachable, and has a wide range of applications. It can be used with any hollow container 13 that can collect liquid. It can be fixed by simply setting four fixing slots 12 on the inner wall of the container 13 and setting the four ends of the two support frames 3 on the fixing slots 12. Users can modify and design the container 13 according to their own needs.

[0023] In actual use, the inlet pipe 9 is positioned at a 45-degree angle to the centrifugal assembly body. Through a pressurized water pump, the inlet pipe 9 delivers pressurized aquaculture wastewater to the centrifugal assembly. The impact force of the water drives the filter screen 4 to rotate continuously. The liquid in the aquaculture wastewater is collected and reused after passing through the filter screen 4. The dirt trapped on the filter screen 4 will be carried to the center of the filter screen 4 by the centrifugal force of the inward inclined side due to its moisture content and discharged along the sewage pipe 8. When too much dirt adheres to the filter screen 4 and cannot flow into the sewage pipe 8, affecting the filtration effect, the flushing water pipe 10 is used to flush the filter screen 4 with pressurized water to flush the dirt into the sewage pipe 8.

[0024] Compared to traditional integrated centrifugal filters, the detachable design of the centrifugal assembly in this invention makes it easier to inspect the internal components for proper functioning, such as checking for bearing wear or bent fasteners, thus improving troubleshooting efficiency. The disassembled filter components are small and lightweight, facilitating handling and transportation, reducing transportation costs and the risk of damage during transport.
