Description

Technical Field

[0001] This utility model relates to the field of aquaculture equipment technology, and in particular to a fish farming filtration device with anti-clogging function. Background Technology

[0002] Aquaculture refers to the production activities of cultivating aquatic organisms (such as fish, shrimp, shellfish, algae, etc.) in freshwater, seawater, or brackish water areas through artificial environmental control.

[0003] In aquaculture, the cleanliness of the water directly affects the living environment and growth of fish. Fish excrement, uneaten feed, and dead plankton are constantly generated in the water. If these impurities are not treated promptly, they accumulate and lead to eutrophication, the growth of harmful microorganisms, and ultimately, fish health and reduced survival rates. Existing fish filtration devices are prone to clogging due to impurities accumulating on and inside the filter media. Clogging requires manual disassembly and cleaning or replacement, increasing labor costs, interrupting the filtration process, disrupting the water's circulation balance, and affecting filtration efficiency and aquaculture stability. This makes it difficult to meet the demands of large-scale, high-efficiency aquaculture, rendering it impractical. Therefore, a new fish filtration device with anti-clogging capabilities needs to be designed to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fish farming filtration device with anti-clogging function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A fish farming filtration device with anti-clogging function includes a filter box. An inlet pipe communicating with the interior is fixedly installed on the outer wall of the filter box. A biological filter media layer is slidably installed inside the filter box via two first support frames. A fine filter cotton layer is slidably installed on the upper surface of the biological filter media layer. A coarse filter screen is slidably installed on the upper surface of the fine filter cotton layer. A water distribution plate cooperating with the inlet pipe is slidably installed inside the filter box via a support mechanism. A reciprocating screw is rotatably installed on the outer wall of the filter box via a connecting frame. A motor connected to the reciprocating screw is fixedly installed on the outer wall of the connecting frame. A screw sleeve is rotatably installed on the outer wall of the reciprocating screw. A limit rod is fixedly installed inside the connecting frame, sliding through the screw sleeve. A scraper cooperating with the upper surface of the coarse filter screen is fixedly connected to the upper surface of the screw sleeve via a connecting mechanism. Two collection boxes cooperating with the scrapers are slidably installed on the outer wall of the filter box via sliding openings. A water pump is fixedly installed on the outer wall of the filter box via a fixing mechanism, with the water pump inlet pipe extending into the interior of the filter box.

[0006] Preferably, the support mechanism includes two second support frames fixedly installed inside the filter box, and the water distribution plate is slidably installed inside the two second support frames.

[0007] Preferably, the connecting mechanism includes a connecting rod fixedly installed on the upper end face of the lead screw sleeve, the outer wall of the filter box has a movable opening that cooperates with the connecting rod, and the end of the connecting rod is fixedly connected to the upper end face of the scraper.

[0008] Preferably, the fixing mechanism includes a fixing plate fixedly installed on the outer wall of the filter box, and the water pump is fixedly installed on the upper end face of the fixing plate.

[0009] Preferably, a sealing plate is fixedly installed on the outer wall of both collection boxes, and multiple bolts are rotatably installed through the outer wall of both sealing plates. The outer wall of the filter box is provided with threaded holes that mate with the multiple bolts, and a sealing gasket is fixedly installed on the inner wall of both sealing plates.

[0010] Preferably, a controller is fixedly installed on the outer wall of the filter box, and the controller is electrically connected to the motor and the water pump.

[0011] The beneficial effects of this utility model are: 1. By setting up components such as a motor, reciprocating lead screw, lead screw sleeve, scraper and collection box, the motor drives the scraper to move automatically along the coarse filter screen to scrape off impurities. The impurities fall directly into the collection box, and cleaning can be completed without disassembling the filter media, reducing maintenance difficulty and labor costs, and ensuring continuous and stable filtration process.

[0012] 2. By setting up components such as a coarse filter screen, a fine filter cotton layer, and a biological filter media layer, the coarse filter screen first intercepts large particulate impurities, then the fine filter cotton layer performs fine filtration, and finally the biological filter media layer degrades organic matter. This avoids the problem of easy clogging of a single filtration structure and significantly improves the filtration effect and water purification capacity. Attached Figure Description

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figures 1-5 A fish farming filtration device with anti-clogging function includes a filter box 1. An inlet pipe 2, communicating with the interior, is fixedly installed on the outer wall of the filter box 1. Inside the filter box 1, a biological filter media layer 4 is slidably installed via two first support frames 3. A fine filter cotton layer 5 is slidably installed on the upper surface of the biological filter media layer 4. A coarse filter screen 6 is slidably installed on the upper surface of the fine filter cotton layer 5. Inside the filter box 1, a water distribution plate 8, which cooperates with the inlet pipe 2, is slidably installed via a support mechanism. A reciprocating screw 10 is rotatably installed on the outer wall of the filter box 1 via a connecting frame 9. The outer wall of the connecting frame 9 is fixedly installed... A motor 11 is fixedly installed and connected to a reciprocating lead screw 10. A lead screw sleeve 13 is rotatably installed on the outer wall of the reciprocating lead screw 10. A limit rod 12 is fixedly installed inside the connecting frame 9. The limit rod 12 slides through the lead screw sleeve 13. A scraper 15 that cooperates with the upper end face of the coarse filter screen 6 is fixedly connected to the upper end face of the lead screw sleeve 13 through a connecting mechanism. Two collection boxes 16 that cooperate with the scraper 15 are slidably installed on the outer wall of the filter box 1 through a sliding opening. A water pump 20 is fixedly installed on the outer wall of the filter box 1 through a fixing mechanism. The inlet pipe of the water pump 20 passes through the interior of the filter box 1.

[0017] Furthermore, the filter box 1 provides a stable mounting carrier for all components of the device. The inlet pipe 2 can introduce the water to be filtered from the aquaculture pond into the filter box 1. The first support frame 3 provides support and limit for the biological filter media layer 4. The sliding installation of the biological filter media layer 4, the fine filter cotton layer 5, and the coarse filter screen 6 facilitates subsequent disassembly and replacement. The water distribution plate 8 can evenly distribute the water flow to the surface of the coarse filter screen 6. The connecting frame 9 provides a mounting base for the reciprocating screw 10 and the motor 11. The scraper 15 can move with the screw sleeve 13 to scrape off impurities from the surface of the coarse filter screen 6. The collection box 16 realizes the centralized collection of impurities. The water pump 20 can drive the filtered water to circulate or realize the backwashing of the filter media.

[0018] The support mechanism includes two second support frames 7 fixedly installed inside the filter box 1, and the water distribution plate 8 is slidably installed inside the two second support frames 7.

[0019] Furthermore, the second support frame 7 is symmetrically arranged on the inner wall of the filter box 1, which not only provides a stable installation support for the water distribution plate 8.

[0020] The connecting mechanism includes a connecting rod 14 fixedly installed on the upper end face of the lead screw sleeve 13. The outer wall of the filter box 1 has a movable opening that cooperates with the connecting rod 14. The end of the connecting rod 14 is fixedly connected to the upper end face of the scraper 15.

[0021] Furthermore, the connecting rod 14 can stably transmit the reciprocating motion of the lead screw sleeve 13 to the scraper 15. The moving opening provides space for the movement of the connecting rod 14, and the edge of the opening is smoothed to avoid jamming when the connecting rod 14 moves, ensuring that the scraper 15 can smoothly move against the surface of the coarse filter screen 6 and improve the impurity removal effect.

[0022] The fixing mechanism includes a fixing plate 19 fixedly installed on the outer wall of the filter box 1, and a water pump 20 fixedly installed on the upper end face of the fixing plate 19.

[0023] Furthermore, the fixing plate 19 is connected to the outer wall of the filter box 1 by welding, which can effectively disperse the vibration generated by the water pump 20 when it is working, prevent the water pump 20 from shifting due to vibration and affecting its working efficiency, and at the same time provide a stable mounting surface for the water pump 20, ensuring the sealing of the connection between the water pump 20 inlet pipe and the filter box 1.

[0024] Both collection boxes 16 have sealing plates 17 fixedly installed on their outer walls. Multiple bolts are rotatably installed on the outer walls of both sealing plates 17. The outer wall of the filter box 1 has threaded holes that mate with the multiple bolts. Both sealing plates 17 have sealing gaskets 18 fixedly installed on their inner walls.

[0025] Furthermore, the sealing gasket 18 can fill the gap between the sealing plate 17 and the outer wall of the filter box 1 to prevent water from leaking from the sliding opening in the filter box 1. The fit between the bolt and the threaded hole facilitates the quick disassembly or installation of the collection box 16 by the staff, making it convenient to clean impurities and ensuring the stability of the collection box 16 after installation.

[0026] A controller 21 is fixedly installed on the outer wall of the filter box 1. The controller 21 is electrically connected to the motor 11 and the water pump 20.

[0027] Furthermore, the controller 21 can set the start and stop time and rotation speed of the motor 11 according to actual usage requirements, so as to realize the scraper 15 automatically and periodically cleans the coarse filter screen 6, reduce manual operation steps, and improve the automation level of the device.

[0028] When using this utility model, first connect the inlet pipe 2 to the outlet of the aquaculture pond to ensure that the water in the aquaculture pond can flow smoothly into the filter box 1. Set the working parameters of the device through the controller 21, including the cleaning interval of the motor 11, the circulation mode and working power of the water pump 20, etc. After starting the device, the water to be filtered in the aquaculture pond flows into the filter box 1 through the inlet pipe 2. The water flow first contacts the water distribution plate 8 and is evenly distributed on the upper surface of the coarse filter screen 6 under the dispersing effect of the water distribution plate 8. The water permeates downward under the action of gravity. When passing through the coarse filter screen 6, the coarse filter screen 6 intercepts larger particles of impurities in the water. The water after preliminary filtration continues to permeate downward to the fine filter cotton layer 5. The fine filter cotton layer 5 intercepts smaller particles of impurities. Then the water permeates to the biological filter material layer 4. The microorganisms attached to the biological filter material layer 4 degrade the organic matter in the water, completing the deep purification of the water. The purified water enters the water pump 20 through the inlet pipe of the water pump 20 under the action of the water pump 20, and is then transported back to the aquaculture pond by the water pump 20, realizing the circulation filtration of the aquaculture water. During the filtration process, when the cleaning time set by the controller 21 is reached, the controller 21 automatically starts the motor 11. The motor 11 drives the reciprocating screw 10 to rotate. The screw sleeve 13 moves axially along the reciprocating screw 10 under the restriction of the limit rod 12. Through the connecting rod 14, it drives the scraper 15 to move back and forth along the upper end face of the coarse filter screen 6. The scraper 15 scrapes away the impurities accumulated on the surface of the coarse filter screen 6. The impurities move to the edge of the filter box 1 under the push of the scraper 15 and fall into the collection boxes 16 on both sides. When the impurities in the collection box 16 accumulate to a certain amount, the operator can turn off the device, unscrew the bolts on the sealing plate 17, remove the collection box 16 from the filter box 1, pour out the internal impurities, put the collection box 16 back in place and tighten the bolts to complete the impurity cleaning.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
