Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to an aquaculture sedimentation microfiltration device. Background Technology

[0002] Aquaculture typically refers to the cultivation of aquatic organisms, including fish, crustaceans, mollusks, and aquatic plants. During the aquaculture process, a large amount of solid suspended matter, uneaten feed, feces, and other impurities accumulate in the aquaculture water. These impurities not only consume dissolved oxygen in the water but also breed bacteria and algae, affecting water quality and threatening the healthy growth of aquatic animals. Therefore, it is often necessary to remove impurities from the water.

[0003] A search revealed that the document with publication number "CN217535752U" states that "this utility model provides an integrated sedimentation and microfiltration machine for aquaculture, relating to the field of aquaculture technology. The integrated sedimentation and microfiltration machine includes an integrated chamber, comprising a sedimentation chamber, a microfiltration chamber, a biological filtration chamber, and a sterilization chamber arranged sequentially. The sedimentation chamber is connected to the microfiltration chamber via a transition port. A microfilter plate is installed inside the microfiltration chamber, with two opposite sides of the microfilter plate respectively designated as the inlet side and the outlet side. The microfilter plate is inclined downwards along the direction from the inlet side to the outlet side, and the transition port is located above the inlet side." In use, the integrated structure of the sedimentation chamber, microfiltration chamber, biological filtration chamber, and sterilization chamber results in a compact design. During water treatment, sedimentation, microfiltration, biological filtration, and sterilization are performed sequentially, resulting in significant water treatment effects. By inclinedly arranging the microfilter plate within the microfiltration chamber, the microfiltration effect is ensured while facilitating the discharge of impurities retained on the microfilter plate, effectively extending the cleaning cycle of the microfilter plate and simplifying operation.

[0004] However, existing devices typically inject water directly into the microfiltration machine, which contains a high amount of impurities. This makes the device prone to clogging during water treatment, and cleaning is difficult, affecting the water treatment effect and reducing the efficiency of water treatment.

[0005] Therefore, we provide a sedimentation microfiltration device for aquaculture to solve the above problems. Utility Model Content

[0006] To overcome the above deficiencies, this utility model provides a sedimentation microfiltration device for aquaculture, which aims to solve the problems mentioned above.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A sedimentation microfiltration device for aquaculture includes a microfiltration body. A support frame is welded to the top of the microfiltration body. A sedimentation filtration assembly is disposed on the inner side of the support frame. The sedimentation filtration assembly includes a treatment tank installed inside the support frame. A connecting frame is welded to the upper side of the inner wall of the treatment tank. An installation ring frame is welded to the inner side of the connecting frame. A connecting groove is formed on the inner wall of the installation ring frame. A filter cylinder is disposed inside the installation ring frame. An outlet is formed at the bottom of the treatment tank. The outlet is connected to the inlet of the microfiltration body.

[0009] Furthermore, the middle section of the filter cartridge has a mesh structure, and the bottom end of the filter cartridge has a sealed structure.

[0010] Furthermore, a connecting strip is welded to the outer wall of the filter cartridge, and the connecting strip is connected to the connecting groove by a slot.

[0011] Furthermore, the outer side of the mounting ring frame has a hollow structure, and a support plate is welded to the bottom inner side of the mounting ring frame.

[0012] Furthermore, a connecting top ring is welded to the top of the filter cartridge, and there is a gap between the connecting top ring and the filter cartridge.

[0013] Furthermore, a primary filter screen is connected to the outer slot of the mounting ring frame, and a secondary filter screen is provided below the primary filter screen. The secondary filter screen is connected to the treatment tank by a slot, and the mesh density of the filter cylinder, the primary filter screen and the secondary filter screen increases progressively.

[0014] Furthermore, a servo motor is installed at the bottom of the mounting ring frame, and a cleaning frame is fixedly connected to the bottom of the servo motor. A cleaning brush is provided on the outside of the cleaning frame. The cleaning brush is made of nylon material and is positioned between the primary filter screen and the secondary filter screen. The upper and lower ends of the cleaning brush are respectively attached to the surfaces of the primary filter screen and the secondary filter screen.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By setting up a sedimentation and filtration component, impurities in the water are filtered and intercepted through the mesh in the middle section of the filter cartridge. At the same time, the impurities below will fall to the bottom of the filter cartridge. When too many impurities accumulate in the filter cartridge, the operator can remove the filter cartridge from the mounting ring frame by connecting the top ring, which increases the convenience of filter cartridge replacement.

[0017] 2. By setting up a sedimentation and filtration component, after the water is filtered once through the filter cartridge, it is then filtered a second and third time through a primary and secondary filter screen. The progressively increasing mesh density can more effectively intercept tiny particulate impurities in the water, improving filtration efficiency and precision. At the same time, a servo motor drives a cleaning brush to brush the primary and secondary filter screens, effectively preventing clogging and ensuring continuous filtration. This greatly reduces the impurity content of the water entering the microfilter, improving the efficiency and effectiveness of water treatment. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 As shown, this utility model provides a technical solution: an aquaculture sedimentation microfiltration device, including a microfiltration body 1, a support frame 2 welded to the top of the microfiltration body 1, a sedimentation filter assembly 3 arranged inside the support frame 2, the sedimentation filter assembly 3 including a treatment tank 301 installed inside the support frame 2, a connecting frame 302 welded to the upper side of the inner wall of the treatment tank 301, an installation ring frame 303 welded to the inner side of the connecting frame 302, a connecting groove 304 opened on the inner wall of the installation ring frame 303, and a filter cylinder 305 arranged inside the installation ring frame 303. During use, the water is pre-treated by the treatment tank 301 and the sedimentation filter assembly 3 to reduce the content of impurities in the water. The bottom end of the treatment tank 301 is provided with a water outlet 313, which is connected to the water inlet of the microfiltration body 1. The treated water then enters the interior of the microfiltration body 1 through the water outlet 313, and the microfiltration machine is used to micro-filter the water to increase the efficiency of water treatment.

[0027] See Figure 1-4 As shown, the middle section of the filter cylinder 305 has a mesh structure, and the bottom of the filter cylinder 305 has a sealed structure. The water to be treated is introduced into the filter cylinder 305, and impurities in the water are filtered and intercepted through the mesh in the middle section of the filter cylinder 305. At the same time, the impurities will fall to the bottom of the filter cylinder 305, which is convenient for collection.

[0028] See Figure 1-4 As shown, a connecting strip 306 is welded to the outer wall of the filter cartridge 305. The connecting strip 306 and the connecting groove 304 are connected by a slot. Through the slot connection between the connecting strip 306 and the connecting groove 304, the filter cartridge 305 can be stably installed on the inner side of the mounting ring 303. At the same time, it is convenient to disassemble and replace the filter cartridge 305, which improves the ease of use and flexibility of the device.

[0029] See Figure 1-4 As shown, the outer side of the mounting ring 303 has a hollow structure, and a support plate is welded to the bottom inner side of the mounting ring 303. The hollow structure on the outer side of the mounting ring 303 increases the flow area of ​​water, allowing water to flow more smoothly through the filter cartridge 305. At the same time, the support plate provides stable support for the filter cartridge 305, ensuring that the filter cartridge 305 will not shake or deform during use, thus ensuring the stability of the device.

[0030] See Figure 1-4 As shown, a connecting top ring 307 is welded to the top of the filter cartridge 305. There is a gap between the connecting top ring 307 and the filter cartridge 305. When too many impurities accumulate in the filter cartridge 305, the operator can remove the filter cartridge 305 from the mounting ring frame 303 through the connecting top ring 307, which increases the convenience of replacing the filter cartridge 305.

[0031] See Figure 1-4 As shown, a primary filter screen 308 is connected to the outer slot of the mounting ring 303. A secondary filter screen 309 is installed below the primary filter screen 308. The secondary filter screen 309 is connected to the treatment tank 301 by a slot. The mesh density on the filter cylinder 305, the primary filter screen 308, and the secondary filter screen 309 increases progressively. After the water is filtered once by the filter cylinder 305, it is filtered a second and third time by the primary filter screen 308 and the secondary filter screen 309. The progressively increasing mesh density can more effectively intercept tiny particulate impurities in the water, improving filtration efficiency and filtration accuracy, and ensuring the quality of the effluent.

[0032] See Figure 1-4 As shown, a servo motor 310 is installed at the bottom of the mounting ring 303. A cleaning frame 311 is fixedly connected to the bottom of the servo motor 310. A cleaning brush 312 is provided on the outer side of the cleaning frame 311. The cleaning brush 312 is made of nylon and is positioned between the primary filter screen 308 and the secondary filter screen 309. The upper and lower ends of the cleaning brush 312 are respectively in contact with the surfaces of the primary filter screen 308 and the secondary filter screen 309. During filtration, the servo motor 310 drives the cleaning frame 311 to rotate between the primary filter screen 308 and the secondary filter screen 309, thereby driving the cleaning brush 312 to brush the primary filter screen 308 and the secondary filter screen 309, cleaning the filter screen, effectively preventing filter screen blockage, and ensuring the continuous filtration effect of the filter screen.

[0033] Working Principle: The device is installed in its working position, and the water to be treated is introduced into the treatment tank 301. The water first undergoes preliminary filtration through the filter cartridge 305, where large particles are trapped. Subsequently, the water undergoes further filtration through a primary filter screen 308 and a secondary filter screen 309. Due to the progressively increasing mesh density, small particles are effectively trapped, thus improving the water purification effect. During the filtration process, the servo motor 310 continuously operates, driving the cleaning brush 312 to rotate between the primary and secondary filter screens 308 and 309, promptly cleaning impurities adhering to the filter screens, preventing clogging, and ensuring continuous filtration effectiveness. Finally, the water, after multi-stage filtration, is discharged through the outlet 313 and enters the microfiltration unit 1 for further microfiltration treatment, thereby achieving highly efficient purification of aquaculture water. This completes the usage process of an aquaculture sedimentation microfiltration device.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
