Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, specifically to a multi-stage filtration and recovery device for aquaculture wastewater. Background Technology

[0002] A multi-stage filtration and recovery device for wastewater refers to equipment that filters wastewater and recovers impurities from it. It is mainly used to treat wastewater generated by aquaculture, mining, etc. Through multi-stage treatment such as physical interception and biological degradation, pollutants are removed and the wastewater is recycled or discharged in compliance with standards. Aquaculture refers to the production activities of breeding, cultivating and harvesting aquatic plants and animals by artificially controlling the aquatic environment and using aquaculture technology. In the process of aquaculture, multi-stage filtration and recovery devices are needed to treat the aquaculture wastewater so that it meets the discharge standards.

[0003] The existing technical solutions have the following drawbacks: when using multi-stage filtration and recovery devices to filter and recover aquaculture wastewater, impurities on the filter plates are scraped off by hand using a scraper. Because the impurities are scraped off by hand, the recovery effect of impurities is low. Therefore, we propose a multi-stage filtration and recovery device for aquaculture wastewater to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-stage filtration and recovery device for aquaculture wastewater, in order to solve the problem that when the multi-stage filtration and recovery device proposed in the background art filters and recovers aquaculture wastewater, the impurities on the filter plate are scraped off by hand using a scraper, which leads to a low recovery effect of impurities.

[0005] To achieve the above objectives, the present invention provides the following technical solution: As a preferred technical solution of the present invention, a multi-stage filtration and recycling device for aquaculture wastewater includes a connecting pool, a connecting pipe fixedly installed on the lower right side of the connecting pipe, and a filtration pool installed on the right side of the connecting pipe. Also includes: A connecting pool has a movable structure on its inner side, and the movable structure includes a fixed scraper, a filter plate and a filter frame. The fixed scraper is installed on the upper side of the inner side of the connecting pool, and a filter plate is provided on the inner side of the inner side of the connecting pool. A filter frame is fixedly installed on the lower left side of the filter plate. An activated carbon plate is installed inside the filter tank, and an installation plate is fixedly installed on the upper side of the activated carbon plate. A disassembly structure is connected to the upper outer side of the filter tank, and the disassembly structure includes a fixing block and a limiting rod. The fixing block is installed on the upper outer side of the filter tank, and the upper outer side of the fixing block is connected to the limiting rod. A microbial purification tank is set on the right side of the filter tank, and an outlet pipe is installed on the lower right side of the microbial purification tank.

[0006] Preferably, a movable block is movably installed on the upper middle side of the connecting pool, and a connecting movable plate is fixedly installed on the upper side of the movable block, and a movable fixed rod is movably connected to the upper inner side of the connecting movable plate.

[0007] Preferably, a water pump is fixedly installed on the right side inside the filter tank, and an inlet pipe is installed on the lower side of the water pump, and a connecting pipe is installed on the right side of the water pump.

[0008] Preferably, an aerator is also fixedly installed on the right side of the interior of the microbial purification tank.

[0009] Preferably, the movable block and the connecting pool are rotatably connected, and the vertical cross-sectional shape of the movable block is a "T" shape.

[0010] Preferably, the movable fixing rod is threadedly connected to the filter plate, and the filter plate is snap-fitted to the connecting pool.

[0011] Preferably, the limiting rod and the fixing block are connected by a thread, and the vertical cross-section of the fixing block is an "L" shaped structure.

[0012] Compared with the prior art, the present invention has at least the following beneficial effects: the multi-stage filtration and recovery device for aquaculture tailwater is provided with a movable structure that can move the filter plate, thereby scraping off the impurities on the filter plate, and is also provided with a disassembly structure that can disassemble the mounting plate, thereby disassembling the activated carbon plate. 1. By flowing the wastewater from the aquaculture pond into the connecting tank, the filter plates installed in the connecting tank filter out large impurities in the wastewater. The filtered wastewater then enters the filter tank through the connecting pipe, where activated carbon plates adsorb and filter the wastewater. The installed water pump is then activated to draw the wastewater from the right side of the filter tank into the connecting pipe through the inlet pipe. The wastewater then enters the microbial purification tank through the connecting pipe, where microorganisms degrade pollutants in the wastewater. The aerator installed on the upper side of the microbial purification tank is then activated to oxygenate the wastewater, thereby purifying the wastewater and facilitating the filtration and treatment of aquaculture wastewater. 2. By rotating the movable fixed rod, the movable fixed rod is threaded onto the inner side of the upper end of the connecting movable plate, thereby moving the movable fixed rod upward and separating it from the upper end of the filter plate. Then, the connecting movable plate is rotated outward, causing the connecting movable plate to drive the movable block to rotate in the upper middle part of the connecting tank, thereby separating the connecting movable plate from the upper side of the filter plate. The filter plate is pulled upward, causing it to slide upward inside the connecting tank, thereby causing the fixed scraper to scrape the impurities on the left side of the filter plate into the inside of the filter frame. This causes the filter plate to drive the filter frame to separate inside the connecting tank, facilitating the recovery of large impurities in the effluent. 3. By rotating the limiting rod, the limiting rod is threaded onto the outer side of the upper end of the fixing block, thereby separating the limiting rod from the outer side of the middle of the mounting plate. Pulling the mounting plate upward causes the mounting plate to slide upward, thereby separating the activated carbon plate from the inner side of the filter tank, making it convenient to disassemble and clean the activated carbon plate.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Please see Figures 1-5 The present invention provides the following technical solution: A multi-stage filtration and recycling device for aquaculture wastewater includes: a connecting tank 1, a fixed scraper 2, a filter plate 3, a filter frame 4, a connecting movable plate 5, a connecting pipe 6, a filter tank 7, an activated carbon plate 8, a mounting plate 9, a mounting water pump 10, an inlet pipe 11, a connecting pipe 12, a microbial purification tank 13, an aerator 14, an outlet pipe 15, a fixed block 16, a movable block 17, a movable fixed rod 18, and a limiting rod 19. When using it for work, specifically such as Figure 1 , Figure 2 and Figure 4 As shown, the filter plate 3 installed inside the connecting pool 1, the connecting pipe 6 fixedly installed on the lower right side of the connecting pool 1, the filter pool 7 fixedly installed on the right side of the connecting pipe 6, the activated carbon plate 8 installed inside the filter pool 7, the water pump 10 fixedly installed on the right side inside the filter pool 7, the inlet pipe 11 installed below the water pump 10, the connecting pipe 12 connected to the right side of the water pump 10, the microbial purification pool 13 installed on the right side of the filter pool 7, the outlet pipe 15 installed on the lower right side of the microbial purification pool 13, and the aerator 14 installed on the right side inside the microbial purification pool 13, all draw the tailwater from the aquaculture pond into the connecting pool 1. This allows the filter plate 3 inside the connecting pool 1 to filter large impurities in the tailwater, so that the filtered tailwater enters the filter pool 7 through the connecting pipe 6. The activated carbon plate 8 inside the filter tank 7 adsorbs and filters the effluent. The installed water pump 10 is started, and the installed water pump 10 draws the effluent from the right side of the filter tank 7 into the connecting pipe 12 through the inlet pipe 11. The effluent then enters the microbial purification tank 13 through the connecting pipe 12, where the microorganisms degrade the pollutants in the effluent. The aerator 14 installed on the upper side of the microbial purification tank 13 is started, and the aerator 14 oxygenates the effluent in the microbial purification tank 13, thereby purifying the effluent. The effluent is then discharged through the outlet pipe 15 on the lower right side of the microbial purification tank 13, facilitating the filtration and treatment of aquaculture effluent. Specific examples Figure 1 , Figure 2 and Figure 3As shown, a movable block 17 is movably connected to the upper side of the middle of the connecting pool 1. A fixed scraper 2 is fixedly installed on the upper side inside the connecting pool 1. A connecting movable plate 5 is fixedly installed on the upper end of the movable block 17. A movable fixed rod 18 is movably connected to the inner side of the upper end of the connecting movable plate 5. The lower end of the movable fixed rod 18 is connected to the upper side of the filter plate 3. A filter frame 4 is fixedly installed on the left side of the lower end of the filter plate 3. By manually turning the movable fixed rod 18, the movable fixed rod 18 is threaded on the inner side of the upper end of the connecting movable plate 5, thereby causing the movable fixed rod 18 to move upward, and thus causing the movable fixed rod 18 to move upward on the upper end of the filter plate 3. Separate the filter plate 3 and rotate the connecting movable plate 5 outwards. This causes the connecting movable plate 5 to drive the movable block 17 to rotate in the upper middle part of the connecting tank 1. This separates the connecting movable plate 5 from the filter plate 3. Then, manually pull the filter plate 3 upwards so that it slides upwards inside the connecting tank 1. This causes the fixed scraper 2 to scrape the impurities on the left side of the filter plate 3 into the filter frame 4. Then, pull the filter plate 3 to the right so that it drives the filter frame 4 to move to the right. This separates the filter plate 3 and the filter frame 4 inside the connecting tank 1, facilitating the recovery of large impurities in the effluent. Specific examples Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a fixing block 16 is fixedly installed on the upper middle side of the filter tank 7. A limiting rod 19 is movably connected to the outer side of the upper end of the fixing block 16. An installation plate 9 is movably connected to the inner side of the limiting rod 19. The lower side of the installation plate 9 is connected to the upper side of the activated carbon plate 8. The limiting rod 19 is manually turned so that it is threaded on the outer side of the upper end of the fixing block 16. Under the action of the thread between the limiting rod 19 and the fixing block 16, the limiting rod 19 moves outward, thereby separating the limiting rod 19 from the outer side of the middle part of the installation plate 9. Then, the installation plate 9 is pulled upward, so that it moves upward under the action of the pulling force. This causes the installation plate 9 to slide the activated carbon plate 8 upward, thereby separating the activated carbon plate 8 from the inner side of the filter tank 7, which facilitates the disassembly and cleaning of the activated carbon plate 8.
