Description

Technical Field

[0001] This utility model belongs to the field of fishpond water purification, and specifically relates to a fishpond water purification and treatment device. Background Technology

[0002] Fishpond water purification refers to the removal of suspended solids, organic matter, nitrogen, phosphorus, and other pollutants from fishpond water through a series of physical, chemical, or biological processes, thereby improving water clarity and ecological balance to ensure the healthy growth of fish. Current fishpond water purification technologies typically include two parts: physical purification and biological purification. For physical purification, granular filtration is commonly used, employing materials such as sand and activated carbon to trap suspended solids and impurities in the water. However, after prolonged use, these granules are prone to clogging, requiring regular cleaning. This cleaning process is cumbersome, necessitating the removal of the granules from the device, and the cleaning effect is often unsatisfactory. Furthermore, the granules need to be replaced frequently, increasing operating costs.

[0003] To address the shortcomings of existing technologies, this invention employs a primary purification component for initial physical filtration to remove large particulate impurities from the water. The primary purification component is designed with a backwashing function to promptly remove the physical filtration particles. Subsequently, a secondary purification component performs biological filtration. Finally, the purified water is introduced into a water purification tank and returned to the fishpond through a return pipe, achieving water quality circulation and purification.

[0020] The following will be based on the embodiments of this utility model. Figures 1-3 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0021] like Figure 1 A fishpond water purification device includes a primary purification component, a secondary purification component, and a water purification tank 18.

[0022] The primary purification component includes a housing 1, an inner cylinder, filter particles 5, a backwash pipe 7, a three-way valve 8, and a sewage pump 10. The inner cylinder is installed inside the housing 1, and the filter particles 5 are disposed inside the inner cylinder. The inner cylinder divides the interior of the housing 1 into an upper chamber and a lower chamber. The input end of the sewage pump 10 is connected to a fishpond, the output end of the sewage pump 10 is connected to the first end of the three-way valve 8, the second end of the three-way valve 8 is connected to the lower chamber, and the third end of the three-way valve 8 is connected to the backwash pipe 7. The backwash pipe 7 is located inside the upper chamber, and its bottom is inserted into the inner cylinder.

[0023] The upper chamber is connected to the secondary purification component via the intermediate pipe 14, the secondary purification component is connected to the water purification tank 18, and the water purification tank 18 is connected to the fishpond via the return water pipe 23.

[0024] The primary purification component of this invention primarily performs physical filtration, while the secondary purification component performs secondary and biological filtration. The water purification tank 18 stores purified water and returns it to the fishpond. Pumps are installed on both the intermediate pipe 14 and the return water pipe 23 to promote water flow. The filter particles 5 are existing technologies, such as silica particles, gravel, and quartz sand, achieving physical filtration. The inner cylinder is located in the middle of the shell 1, with an upper chamber above and a lower chamber below. The input end of the sewage pump 10 can be connected to the fishpond and tap water via a three-way valve.

[0025] In a specific implementation of this utility model, during the purification of fishpond water, the three-way valve 8 connects the first end and the second end, and the sewage pump 10 connects to the fishpond. The water in the fishpond enters the lower chamber of the shell 1 through the pumping pipe and the sewage pump 10. The sewage in the lower chamber passes through the inner cylinder and the filter particles 5 from bottom to top, forming physical purification and removing impurities such as particulate matter and organic matter. The physically purified water is stored in the upper chamber and enters the secondary purification component through the intermediate pipe 14 and the water pump 13 on the intermediate pipe 14. The water purified by the secondary purification component is output to the water purification tank 18. The purified water in the water purification tank 18 is returned to the fishpond through the return pipe 23 and the pump body, thus finally achieving the purification treatment of the fishpond water. In this invention, during particle cleaning, a three-way valve 8 connects the first and third ends, and a wastewater pump 10 connects to tap water. The filter particles 5 are backwashed through the backwash pipe 7. The backwash water flows from the inside out and from top to bottom, causing the filter particles 5 to move irregularly within the inner cylinder, thus thoroughly cleaning them. The wastewater after rinsing flows from top to bottom from the inner cylinder into the lower chamber. Additionally, a drain port 12 is provided at the bottom of the housing 1. A corresponding valve can be installed on the drain port 12; after particle cleaning, the drain port 12 is opened to discharge the wastewater.

[0026] This invention, through the structure of inserting the backwash pipe 7 into the filter particles 5, can effectively clean the filter particles 5, avoid clogging, and improve purification efficiency. Furthermore, during fishpond water purification, the sludge and particles formed settle in the lower chamber. After the particles are cleaned, the sludge generated during flushing and purification can be discharged together. This invention solves the problem of easy clogging of the filter particles 5 in the prior art, avoiding the need to replace the filter particles 5 and making physical filtration more efficient and durable.

[0027] Furthermore, the inner cylinder includes a hollow cylinder 4 and two mesh plates 3. The hollow cylinder 4 is filled with the filter particles 5. The two ends of the hollow cylinder 4 are detachably connected to the mesh plates 3 by bolts. The backwash pipe 7 passes through the mesh plate 3 located above.

[0028] The mesh plate 3 has a mesh structure, and its mesh holes are used for water to pass through. The upper and lower mesh plates 3 fix the filter particles 5 inside the hollow cylinder 4.

[0029] Furthermore, a support block 2 is fixedly connected inside the housing 1, and the grid plate 3 located below abuts against the support block 2.

[0030] Specifically, the support block 2 supports the grid plate 3 below, and corresponding bolts can be set on the outer side of the shell 1 to lock the hollow cylinder 4, so as to support and fix the inner cylinder and facilitate the installation and removal of the inner cylinder.

[0031] Furthermore, the second end of the three-way valve 8 is fixedly connected to the lower branch pipe 11, the lower branch pipe 11 is connected to the lower chamber, the third end of the three-way valve 8 is fixedly connected to the upper branch pipe 9, multiple backflush pipes 7 are provided, and the top of the backflush pipe 7 is detachably connected to the upper branch pipe 9.

[0032] Specifically, to prevent sewage backflow, the lower branch pipe 11 is installed vertically, and its top is connected to the second end of the three-way valve 8.

[0033] Furthermore, the backflush pipe 7 is provided with multiple nozzles 6.

[0034] The top of the backwash pipe 7 can be connected to the upper branch pipe 9 via flanges, water pipe joints, etc. The bottom of the backwash pipe 7 is fixedly connected to the mesh plate 3 located below. After the filter particles 5 are filled into the hollow cylinder 4, the mesh plate 3 located above is installed. During particle cleaning, backwash water enters multiple backwash pipes 7 through the three-way valve 8 and the upper branch pipe 9, and is sprayed out through the nozzles 6. Multiple nozzles 6 are arranged side by side to achieve effective rinsing of various positions of the filter particles 5.

[0035] like Figure 2 , Figure 3 The secondary purification component includes a hollow shell 15, a support plate 16, and biological filter particles 21. The top of the hollow shell 15 is connected to the intermediate pipe 14, and the bottom of the hollow shell 15 is connected to the water purification tank 18. The support plate 16 is detachably installed inside the hollow shell 15. The support plate 16 is provided with a groove to accommodate the biological filter particles 21, and a support net 22 is provided at the bottom of the groove.

[0036] The hollow outer shell 15 can be supported and fixed by a bracket. The intermediate tube 14 is located above the biofilter particles 21, which are existing technologies, such as bio-activated carbon. The function of the support net 22 is to support the biofilter particles 21.

[0037] After physical purification by the primary purification components, the water enters the top of the hollow shell 15 through the intermediate pipe 14. The water passes through the biological filter particles 21 and the support net 22 from top to bottom, forming a biological filter for the water and enhancing the degradation capacity of organic matter in the water.

[0038] Furthermore, the hollow outer shell 15 has an opening on its side for the support plate 16 to be inserted, and a guide rail 17 is fixedly connected to the inner wall of the hollow outer shell 15, the guide rail 17 supporting the support plate 16.

[0039] The support plate 16 is connected to the hollow shell 15 by a pull-out mechanism. By pulling out the support plate 16, the biofilter particles 21 can be replaced, facilitating regular replacement of the biofilter particles 21. In addition, the support plate 16 is externally fixedly connected to a sealing plate 20. The sealing plate 20 can be bolted to the outer side of the hollow shell 15, and a sealing ring can be provided between the sealing plate 20 and the outer side of the hollow shell 15 to improve the sealing performance.

[0040] Guide rails 17 are provided on both sides of the bottom of the support plate 16. Rollers can be installed on the guide rails 17 to facilitate the pulling and supporting of the support plate 16.

[0041] Furthermore, multiple support plates 16 are arranged side by side vertically. Through the layer-by-layer filtration of biological filter particles 21 on multiple support plates 16, the water purification effect can be further improved.
