Description

Technical Field

[0001] This utility model relates to a microfilter, and more particularly to a flat plate screen type microfilter for fish ponds, belonging to the field of filtration and treatment technology for circulating water in aquaculture. Background Technology

[0002] In the aquaculture industry, recirculating aquaculture systems (RAS) are one of the core technologies for achieving energy-saving, environmentally friendly, and high-density farming. Under this system, fish waste, uneaten feed, and other solid pollutants continuously accumulate in the water. If not removed promptly, this can lead to increased concentrations of ammonia nitrogen and nitrite, pH imbalance, and consequently affect the growth and development of farmed organisms. Mild cases may result in slowed growth and reduced immunity, while severe cases can lead to disease outbreaks or even large-scale mortality, causing significant economic losses.

[0003] Most mainstream microfiltration machines for fish ponds on the market are drum-type or arc-shaped screen-type. They have many internal transmission components and tortuous flow channels, making it easy for dirt to accumulate in the folds of the screen or the gaps in the transmission, leading to frequent blockages. After blockage, the screen needs to be repeatedly flushed with a high-pressure water pump, and the flushing process consumes additional electricity and water, resulting in high operating costs. In addition, the transmission components and filter components are arranged in a cross pattern, making disassembly and repair after failure cumbersome. Furthermore, drum-type equipment requires reserved space for rotation, and its footprint is usually 1-2 times that of equipment with the same processing capacity, making it unsuitable for small-scale farms or indoor intensive aquaculture scenarios.

[0004] Therefore, it is urgent to improve the flat plate screen microfiltration machine for fish ponds to solve the above-mentioned problems. Utility Model Content

[0016] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0017] like Figures 1-6As shown, the fishpond flat-panel microfiltration machine provided in this embodiment includes a box 1 with an opening at the top. The box 1 can be made of stainless steel or aluminum alloy, and the choice is not limited according to the actual working conditions. A box cover 2 is hinged to the opening of the box 1. The box 1 contains a filter chamber 3 and a clear water chamber 4 arranged vertically below the filter chamber 3. When the box cover 2 is opened, the filter chamber 3 can be exposed, which facilitates the maintenance of the structure inside the filter chamber 3 and allows the user to observe the filtration status inside the filter chamber 3. In order to facilitate the use of the box cover 2, a support angle plate 19 is provided inside the filter chamber 3. A support rod 20 can be set between the support angle plate 19 and the box cover 2. The two ends of the support rod 20 will abut against the box cover 2 and the support angle plate 19 respectively, so that the box cover 2 does not need to be held by the user at all times during use. In order to introduce water into the filter chamber 3, therefore... The housing 1 is equipped with a water inlet pipe, which includes a diversion pipe 18 and several guide pipes 17. The output ends of the guide pipes 17 are all connected to the interior of the diversion pipe 18. The diversion pipe 18 is arranged parallel to the surface of the flat screen 6 and its two ends are connected. The input ends of the guide pipes 17 can be connected to the sewage discharge end. The guide pipes 17 can increase the amount of sewage discharged into the filter chamber 3. While the diversion pipe 18 collects the sewage output from the guide pipes 17, it can also disperse the sewage to both ends of the diversion pipe 18 before it falls onto the flat screen 6. This avoids the sewage output from the guide pipes 17 being sprayed directly onto the flat screen 6, thus preventing damage to the flat screen 6. Furthermore, the diversion pipe 18 slows down the initial water velocity when the sewage enters the filter chamber 3, making it easier for the flat screen 6 to filter the sewage.

[0018] The output end of the inlet pipe extends into the interior of the filter chamber 3. Below the filter chamber 3 and on one side of the clear water chamber 4, there is a wastewater chamber 5 connected to the filter chamber 3. A flat screen 6 is provided between the filter chamber 3 and the clear water chamber 4. The filter chamber 3 is equipped with a cleaning mechanism for cleaning impurities on the flat screen 6. The cleaning mechanism sweeps the impurities filtered from the surface of the flat screen 6 toward the input end of the wastewater chamber 5. The wastewater after filtration becomes clear water, which enters the clear water chamber 4. A discharge pipe 21 is connected to the output end of the clear water chamber 4 to facilitate the discharge of the clear water in the clear water chamber 4 into the fish pond.

[0019] It should be noted that the flat screen 6 is an existing technology structure, mainly used for filtering sewage. The inner wall of the filter chamber 3 is provided with protrusions to support the flat screen 6. The flat screen 6 is provided with filter holes, which can filter impurities in the sewage. In order to facilitate the use of the device, the gap of the filter holes of the flat screen 6 is 15-1000μm. In specific implementation, the flat screen 6 of different sizes can be selected according to different working conditions, and no limitation is made here.

[0020] The cleaning mechanism includes two rotating parts linearly arranged along the surface of the flat screen 6, two symmetrically and parallelly arranged transmission chains 7, brushes 9, and a driving component. Several brushes 9 are provided, each connected to one of the two transmission chains 7. The connection between the brushes 9 and the transmission chains 7 can be achieved by welding or bolting, both existing and conventional fixing methods, without limitation or detailed description. The brushes 9 make active contact with the surface of the flat screen 6. The brushes 9 can be made of plastic soft bristles or other soft materials, without limitation, to avoid damage to the flat screen 6. The number of brushes 9 can be increased as needed to achieve a better cleaning effect on the flat screen 6.

[0021] The rotating component consists of a rotating shaft 8 and two chain teeth 10 connected to the rotating shaft 8. The axial direction of the rotating shaft 8 is parallel to the width direction of the flat screen 6, and the extension direction of the brush 9 is parallel to the axial direction of the rotating shaft 8. The rotating shaft 8 is rotatably connected to the housing 1 through a bearing seat. The rotating shafts 8 on the two rotating components are arranged in parallel, and the two chain teeth 10 are arranged along the axial direction of the rotating shaft 8. The transmission chain 7 is sleeved on the two corresponding chain teeth 10 on the two rotating components. When one of the rotating components is running, its rotating shaft 8 will drive the corresponding two chain teeth 10 to rotate, and then drive the chain teeth 10 on the other rotating component to rotate through the transmission chain 7, and then drive the rotating shaft 8 connected to the chain teeth 10 to rotate. Under the action of the transmission chain 7, the two rotating components can achieve synchronous rotation. The transmission chain 7 serves to fix the brush 9 and also serves to transmit power between the two rotating components.

[0022] Furthermore, the driving component is used to drive one of the rotating components. Specifically, the driving component includes a drive motor 11 installed outside the housing 1, a second chain tooth 12, a third chain tooth 13 connected to the output end of the drive motor 11, and a second transmission chain 14 sleeved on the third chain tooth 13 and the second chain tooth 12. Among them, a protective plate 15 is provided above the drive motor 11. One end of one of the rotating shafts 8 extends through the housing 1 to the outside and is connected to the second chain tooth 12. The drive motor 11 drives the third chain tooth 13 to rotate, which in turn drives the second chain tooth 12 to rotate through the second transmission chain 14, thereby driving the rotating shaft 8 connected to the second chain tooth 12 to rotate. Finally, the two rotating components run synchronously and drive the brush 9 to move. In order to achieve the purpose of the brush 9 cleaning the surface of the flat screen 6, the rotating shaft 8 rotates away from the sewage tank 5. That is, when the rotating shaft 8 rotates, it will drive the brush 9 to sweep the impurities on the surface of the flat screen 6 in the opposite direction to the sewage tank 5.

[0023] To facilitate the control of the drive components, a controller electrically connected to the drive motor is installed on the housing. The controller has a switch (not shown in the figure), which is a common existing device. During use, the controller can be manually operated to start the drive motor or adjust the power of the drive components, or to preset the start time and power of the drive motor, thereby reducing the number of manual operation steps and achieving the purpose of automated operation. The specific use can be determined according to the working conditions, and no restrictions are imposed here.

[0024] Furthermore, an arc-shaped scraper 16 is provided at the input end of the sewage tank 5. The arc-shaped scraper 16 is adapted to the movement trajectory of the brush 9 and can scrape and clean the impurities or feces attached to the brush 9, keeping the brush 9 clean. A sewage pipe 22 is connected to the output end of the sewage tank 5 to facilitate the discharge of impurities or feces flowing into the sewage tank 5.

[0025] The filter chamber 3 and the clear water chamber 4 mentioned above are separated by a flat screen 6, which can achieve the filtration requirements more efficiently. When the transmission chain 7 circulates and rolls the brush 9, the flat screen 6 will not be blocked. It is suitable for long-term uninterrupted operation, and its filtration accuracy and efficiency are higher. At the same time, it can also be applied to sewage treatment in other industrial fields. Its structure is simple, its failure rate is low, and its equipment cost is low.
