Description

Technical Field

[0001] This utility model mainly relates to the technical field of aquaculture water filtration, specifically a sewage discharge system based on rotating filter basket technology. Background Technology

[0002] In current aquaculture technology, fish farming is extremely important. Whether in fishponds or aquariums, large amounts of uneaten feed and animal excrement generate significant amounts of pollutants such as ammonia nitrogen, nitrite, and sulfides. These pollutants not only pollute water bodies, making wastewater turbid and affecting the health of organisms, but also reduce the survival rate of farmed fish.

[0003] Through exploration and research on existing filtration structures, we discovered that using a dynamic rotating filter basket for filtration generates a centrifugal effect. Combined with water flow impact, this effectively intercepts impurities while preventing accumulation and clogging. While this technology reduces the frequency of manual cleaning, further research into dynamic filtration technology for clogging prevention aims to extend the anti-clogging time and address the issue of removing accumulated impurities, further reducing manual cleaning workload. Therefore, this application will develop a...

[0004] This utility model mainly provides a sewage discharge system based on rotating filter basket technology to solve the technical problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A sewage discharge system based on rotating filter basket technology includes a dynamic filter basket filtration mechanism, which is located in an upper filter box and connected to a filter inlet pipe through a first diversion pipe. The lower end of the upper filter box is connected to a lower filter box, the upper filter box is connected to a filter outlet pipe, and the lower filter box is connected to a filter impurity discharge valve. The first diversion pipe includes a top connecting pipe located above the filter basket, which is water-passing and continues to send water along the pipe to a second diversion pipe.

[0007] The top connecting pipe is connected to the upper fixing pipe below, and the upper fixing pipe is provided with an upper connecting cover and is connected by a nut through a threaded connection.

[0008] The upper connecting cover is connected to a brim base below, and a sludge collecting wheel is provided below the brim base. The sludge collecting wheel includes a wheel spindle, a wheel frame, a passage, sludge collecting blades, and a protrusion. Multiple wheel frames are fixed to the bottom outer wall of the wheel spindle, and a passage is provided between the multiple wheel frames. Sludge collecting blades are evenly distributed around the center point on the upper surface of the sludge collecting wheel, and a protrusion is provided on the lower surface.

[0009] Below the sludge collecting wheel is a funnel-shaped sludge collection pipe, and the convex bulge is aligned with the inside of the funnel-shaped opening at the top of the funnel-shaped sludge collection pipe.

[0010] Furthermore, the nut is movably sleeved on the top of the upper connecting cover, and after being threadedly connected to the bottom of the upper fixing tube, the nut presses the upper connecting cover and fixes it on the upper fixing tube.

[0011] Furthermore, the brim base includes a round brim piece, a base inner groove, a second bearing, and a third bearing. The base inner groove is opened at the center of the bottom of the brim base. The second bearing and the third bearing are respectively embedded and fixed in the base inner groove. The second bearing is located above the third bearing. The wheel spindle is sequentially inserted and fixed in the second bearing and the third bearing.

[0012] Furthermore, a first bearing is fitted and fixed on the outer wall of the flared-mouth sewage collection pipe located below the flared mouth. The first bearing is embedded and fixed in the inner bottom of the filter basket. After the flared-mouth sewage collection pipe passes through the filter basket, it is connected to a bottom sewage connector, and the bottom of the bottom sewage connector is connected to a fixed seat.

[0013] Furthermore, the fixed base has a water passage space inside, which is used to connect the bottom drain connector and the main drain pipe for water discharge. The main drain pipe is connected to the lower filter box.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. Through the coordinated design of the dynamic filter basket filtration mechanism and the sludge collection wheel, water flow drives the sludge collection wheel to rotate, causing impurities to collect along the sludge collection blades under centrifugal force and be discharged through the funnel-shaped discharge pipe, significantly improving discharge efficiency and reducing the risk of filter screen clogging. The optimized layout of the top connecting pipe and the diversion pipe ensures uniform water flow distribution, while the threaded connection structure between the upper connecting cover and the cap base facilitates disassembly and maintenance, reducing operation and maintenance costs.

[0016] 2. The alignment design of the convex bulge of the sludge collection wheel with the flared drain pipe enhances the impurity guiding effect, and the multi-bearing supported wheel spindle ensures more stable operation.

[0024] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0025] like Figures 1 to 5 As shown, this embodiment provides a wastewater discharge system based on rotating filter basket technology. The system dynamically filters aquaculture wastewater using the filter basket provided by this technology, collecting impurities and discharging them from the bottom of the filter basket 11. The specific solution includes the following:

[0026] The dynamic filter basket filtration mechanism 1 is located in the upper filter box 2 and is connected to the filter inlet pipe 4 through the first diversion pipe 6. The lower end of the upper filter box 2 is connected to the lower filter box 3. The upper filter box 2 is connected to the filter outlet pipe 5. The lower filter box 3 is connected to the filter impurity discharge valve 8. The aquaculture wastewater is pumped from the aquaculture pond or aquarium of aquaculture fish and filtered through the filter inlet pipe 4 to the dynamic filter basket filtration mechanism 1. The filtered impurities are collected and treated in the filter basket 11 and discharged from the bottom. The filtered water enters the upper filter box 2 and is pressurized by the pump and returned to the aquaculture pond or aquarium through the filter outlet pipe 5.

[0027] The dynamic filter basket filtration mechanism 1 includes a rotatable filter basket 11 and a first diversion pipe 6 located above the filter basket 11. The first diversion pipe 6 is vertically arranged in an U-shape in the upper filter box 2, and a second diversion pipe 7, also in an U-shape, is horizontally arranged on the first diversion pipe 6 and above the upper filter box 2. The second diversion pipe 7 includes a diversion intermediate pipe 71, and four diversion spray heads 72 are equally distributed in the space enclosed by the diversion intermediate pipe 71. The four diversion spray heads 72 are... The filter basket 11 is located above the filter basket 11, and the outlets of the diversion spray heads 72 are aligned in a uniform direction with the inner wall of the filter basket 11. The diversion spray heads 72 and the diversion intermediate pipe 71 are connected for water discharge. The first diversion pipe 6 and the second diversion pipe 7 are also connected to water, which facilitates the filtration of the wastewater to be filtered transported by the filter inlet pipe 4. Under the impact of water flow, the filter basket 11 will rotate, thereby performing dynamic water filtration. The filter pore diameter of the filter basket 11 is usually between 100-200 mesh. If finer filtration is required, filter cloth or similar filter materials can be added to the inner wall.

[0028] Regarding the stability of the filter basket 11, the material of the filter basket 11 can be aluminum alloy or stainless steel, which are water-resistant and have a certain weight. In this technical solution, the weight of the filter basket 11 can be increased to ensure a certain stability. However, the weight specification should be such that it can generate a certain speed of rotation under the impact of water flow. Therefore, the stability of the rotation of the filter basket 11 needs to be configured based on the current usage requirements. The bottom of the filter basket 11 is rotatably connected to the funnel-shaped sewage collection pipe 16 through the first bearing 111, which has a strong stable structural capability.

[0029] Regarding the core technology of the sewage system, the first diversion pipeline 6 includes a top connecting pipe 61 located above the filter basket 11. The top connecting pipe 61 is water-carrying and continues to send water along the pipeline to the second diversion pipeline 7. The top connecting pipe 61 is connected to an upper fixed pipe 62 below it. The upper fixed pipe 62 is not water-carrying. An upper connecting cover 12 is provided below the upper fixed pipe 62 and is threadedly connected by a nut 13. The nut 13 is movably sleeved on the top of the upper connecting cover 12. After being threadedly connected to the bottom of the upper fixed pipe 62, the nut 13 presses the upper connecting cover 12 and fixes it on the upper fixed pipe 62.

[0030] Below the upper connecting cover 12, there is a brim base 14. The brim base 14 is fixed inside the upper connecting cover 12 by a top protrusion rod. The brim base 14 includes a round brim piece 141, a base inner groove 142, a second bearing 143, and a third bearing 144. The base inner groove 142 is opened at the center of the bottom of the brim base 14. The second bearing 143 and the third bearing 144 are respectively embedded and fixed in the base inner groove 142. The second bearing 143 is located above the third bearing 144.

[0031] Below the brim base 14, there is a dirt collection wheel 15. The dirt collection wheel 15 includes a wheel main shaft 151, a wheel frame 152, a passage 153, dirt collection blades 154, and a protrusion 155. The wheel main shaft 151 is sequentially inserted and fixed in the second bearing 143 and the third bearing 144. Multiple wheel frames 152 are fixed on the bottom outer wall of the wheel main shaft 151. Passage 153 is provided between the multiple wheel frames 152. The dirt collection wheel 15 has dirt collection blades 154 evenly distributed around the center point on the upper surface and a protrusion 155 on the lower surface.

[0032] Below the sludge collecting wheel 15 is a funnel-shaped sludge collection pipe 16. The protrusion 155 is aligned with the inside of the funnel at the top of the funnel. A first bearing 111 is fixedly fitted on the outer wall of the funnel-shaped sludge collection pipe 16 below the funnel. The first bearing 111 is embedded and fixed in the inner bottom of the filter basket 11. After passing through the filter basket 11, the funnel-shaped sludge collection pipe 16 is connected to a bottom sludge connector 17. The bottom of the bottom sludge connector 17 is connected to a fixed seat 18. The two ends of the fixed seat 18 are connected to the first diversion pipe 6 through closed pipes. However, this closed pipe does not carry water. The fixed seat 18 has a water passage space inside, which is used to connect the bottom sludge connector 17 and the main sludge pipe 19 for water discharge. The main sludge pipe 19 is connected to the lower filter box 3.

[0033] The mounting base 18 can be fixed to the bottom of the upper filter box 2 using a conventional pipe fixing method. As long as stability is ensured, and considering the overall structure of the first diversion pipeline 6, the stability of its structure is guaranteed.

[0034] A filter impurity discharge valve 8 is connected to the bottom outer wall of one end of the lower filter box 3. The filter impurity discharge valve 8 is used to connect to the external impurity recovery pipeline to recover fish excrement or food residue in the aquaculture pond into the biological bacteria cultivation system.

[0035] In this embodiment, the impurities and some water remaining after filtration by the filter basket 11 flow down to the collection wheel 15 as the filter basket 11 rotates. At this time, the collection blades 154 on the collection wheel 15 are also affected by the water flow, driving the collection wheel 15 to rotate, which facilitates the collection of impurities from all angles and prevents the sedimentation of impurities caused by stillness. The cap base 14 above serves as a partial water-blocking structure, and its main function is to enhance the collection capacity during the collection of impurities. Furthermore, the water flow impacting the cap base 14 will create a backsplash that hits the inner wall of the filter basket 11, keeping the water and impurities in a constantly moving state. This is equivalent to deflecting some of the water that directly impacts the sludge collection wheel 15, allowing it to return and be filtered again by the filter basket 11 to screen the impurities. At the same time, it also reduces the water flow that gathers at the sludge collection wheel 15 to a certain extent, preventing excessive water from flowing directly into the lower filter box 3. In addition, it can better screen out impurities during the frequent impact and splashing process. In particular, the impurities after the impact flow along the residual water that has not been completely splashed back to the sludge collection wheel 15, and then gather from the channel provided by the sludge collection blade 154 to the corresponding through port 153, and finally enter the funnel-shaped sewage collection pipe 16.

[0036] In addition, in this embodiment, the first diversion pipe 6 guides water to the second diversion pipe 7 through the filter inlet pipe 4, and then diverts it from the diversion middle pipe 71 to each diversion spray head 72. The sewage enters the filter basket 11 for filtration. Due to the uniform setting of the spray angle direction, it can be clockwise or counterclockwise. At the same time, the spray can drive the filter basket 11 to rotate for filtration. The water filtered in the first time enters the upper filter box 2. Then the upper filter box 2 is improved to be connected to the filter outlet pipe 5, so that the water filtered in the first time can be returned to the breeding pond. Then the remaining water and the filtered impurities flow through the through port 153 on the sludge collection wheel 15 to the funnel-mouth sewage collection pipe 16. The funnel-mouth sewage collection pipe 16 and the bottom sewage connector 17 are connected. The remaining water and the filtered impurities continue to be guided from the inside of the fixed seat 18 and the main sewage pipe 19 to the lower filter box 3.

[0037] Based on the known technical features of some conventional filtration technologies, a multi-layer filtration assembly (which can be configured according to requirements) is vertically installed in the lower filter box 3 to purify the sewage delivered from the main drain pipe 19. In addition to the sewage isolation area of ​​the multi-layer filtration assembly, a purified water retention area is also set in the lower filter box 3. The retention area is usually located on one side of the box, occupying one-third of the box space. It is separated by the multi-layer filtration assembly. In the retention area, a submersible pump sends water back to the upper filter box 2 along the pipe. The end of the pipe that passes through the upper filter box 2 is equipped with a one-way valve, which allows water to enter the upper filter box 2 but cannot return. This part of the technology can be set up based on existing technology. Among them, the filter impurity discharge valve 8 is close to the sewage isolation area.

[0038] This embodiment of the wastewater discharge system based on rotating filter basket technology achieves preliminary dynamic filtration of wastewater through the dynamic filter basket filtration mechanism 1. The water flow impact drives the filter basket 11 to rotate, improving filtration efficiency while reducing impurity clogging. Further deep filtration through the lower filter box 3 effectively removes various impurities and harmful substances from the water, ensuring the cleanliness of the aquaculture water. The entire system has a reasonable structural design, stable operation, and can be widely applied to wastewater purification in fish farming ponds, ornamental fish tanks, and other similar settings.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
