Description

Technical Field

[0001] This utility model relates to the field of filtration in aquaculture, specifically a filtration device for aquaculture that is easy to maintain. Background Technology

[0002] The aquaculture industry has extremely high requirements for water quality management. The aquaculture water not only contains a large number of suspended particles, fish food residues, and metabolic waste, but may also contain organic pollutants and harmful nitrogen compounds. If these substances are not cleaned or degraded in time, the water quality is prone to deterioration, leading to slow growth, decreased immunity, and even large-scale mortality of farmed organisms, which seriously affects the aquaculture efficiency. At this time, it is necessary to filter the water in the aquaculture tank through a filtration device. The filtration device consists of an inlet guide chamber, a pre-filter cartridge, a mechanical filter layer, a biological purification bed, and an outlet return section. The wastewater entering the filtration device is first guided and evenly distributed in the guide chamber to enter the pre-filter cartridge for interception and preliminary sedimentation of coarse particles. Then, the remaining water flows through the mechanical filter layer to further remove impurities from medium suspended solids. At the same time, the microorganisms fixed on the surface of the filter layer and the biological purification bed continue to decompose dissolved pollutants such as ammonia nitrogen and nitrite. Finally, the water is discharged uniformly through the outlet return section to ensure that the water body achieves purification of particles and dissolved pollutants through the combined action of mechanical and biological processes.

[0003] In the prior art, such as a filter device for aquaculture that is easy to maintain, with application number CN202420246765.2, a filter box, a water pump, a water supply pipe, a connecting pipe, and a guide frame are used. In use, the water pump sends the water containing residue in the aquaculture tank through the water supply pipe, the connecting pipe, and the guide frame into the filter box for filtration. After being filtered by the third filter frame, the second filter frame, and the first filter frame, the water cleanliness is increased before it flows back into the aquaculture tank. When it is necessary to clean the inside of the filter box, the connecting pipe is rotated to move the guide frame away from the filter box, so that the third filter frame, the second filter frame, and the first filter frame inside the filter box can be removed in sequence for cleaning, which improves the convenience of residue cleaning.

[0004] However, in actual use, the filter plate at the bottom of the aquaculture tank comes into contact with the aquaculture water first, and the aquaculture water contains a lot of impurities, making it very easy to get clogged. This consumable part needs to be replaced frequently, and because it is installed with multiple sets of bolts, it is very easy to get stuck when disassembling. Utility Model Content

[0005] The purpose of this invention is to provide a filtration device for aquaculture that is easy to maintain, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a filtration device installed on the side of a breeding box, a water pump drawing water from inside the breeding box, an inlet pipe at the pump input end, an outlet pipe for the filtration device, and a filter plate installed at the bottom of the breeding box. The inner wall of the breeding box has a first groove, and the inner wall of the filter plate has a second groove. A locking structure slides within the first groove, used to lock the filter plate. Support plates are fixed at the four corners of the inner wall of the breeding box, and the filter plate is placed on the upper surface of the support plates. The locking structure is unlocked by a pushing mechanism.

[0007] Preferably, the inlet of the water inlet pipe is located below the filter plate, and the outlet pipe is located above the filter plate.

[0008] Preferably, there are four sets of groove one and groove two, and the groove one and groove two in each set are flush, the groove two is an "L" shaped groove, and the groove one and groove two correspond one to one.

[0009] Preferably, the filter plate has a groove on its edge, the groove is located on the bottom surface of the filter plate, and the groove is connected to the groove.

[0010] Preferably, the locking structure includes a spring, a top block, and a locking block. One end of the spring is connected to the inner bottom surface of the first groove, and the other end of the spring is connected to the bottom surface of the top block. The top block slides in the first groove, and the top of the top block has an isosceles trapezoidal structure. A limit block is fixed at the opening of the first groove, and the foot of the top block is limited by the limit block. There are two sets of locking blocks, and the two sets of locking blocks are fixed to the inner wall of the second groove. The two sets of locking blocks are located on the upper and lower surfaces of the second groove. The locking blocks have a right-angled trapezoidal structure, and the hypotenuse of the locking block contacts the two hypotenuses of the top block.

[0011] Preferably, the pushing structure includes a rotating rod, a connecting plate, and a protrusion. The rotating rod rotates inside the filter plate, with one end of the rotating rod located above the filter plate and the other end located in the second groove. The connecting plate is fixed to the outside of the rotating rod, and the protrusion is fixed to the outside of the connecting plate. The protrusion has an isosceles trapezoidal cross-section, with arc-shaped corners on both sides. The protrusion is flush with the top block and is located between two sets of locking blocks. Both the connecting plate and the protrusion are located in the second groove.

[0012] Preferably, the top surface of the filter plate is provided with a slot, which is located directly above the top block. One end of the rotating rod is equipped with a locking rod, which can be inserted into the slot and is located directly above the protrusion.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This utility model proposes an easy-to-maintain filtration device for aquaculture. Since aquaculture water contains many impurities, the bottom filter plate needs frequent replacement. By placing the filter plate on a support plate, the inclined edges on both sides of the top block first contact the bottom of the filter plate. As the filter plate moves downwards, the top block moves along the groove on the bottom of the filter plate until it enters the second groove. Due to the spring force, the top block engages between two sets of locking blocks, thus forming a lock. If disassembly is required, simply rotate the rotating rod so that the protrusion on the outside of the rod contacts the top block, and then gradually push the top block to disengage it from the second groove, allowing it to move freely into the groove without being restricted. This facilitates the replacement of filter plates with different pore sizes to adapt to different water qualities.

[0015] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Example 1 Please see Figures 1-6This utility model provides a technical solution: a filter device for easy maintenance in aquaculture, including a filter device 4, which is installed on the side of the aquaculture tank 1, a water pump 2 that draws water from the aquaculture tank 1, an inlet pipe 3 at the input end of the water pump 2, an outlet pipe 5 at the discharge end of the filter device 4, a filter plate 6 installed at the bottom of the aquaculture tank 1, the inlet of the inlet pipe 3 being located below the filter plate 6, and the outlet pipe 5 being located above the filter plate 6, a groove 8 is provided on the inner wall of the aquaculture tank 1, and a groove 12 is provided on the inner wall of the filter plate 6, with four sets of grooves 8 and 12, and each set of grooves 8 and 12 being flush, and groove 12 being L-shaped, with grooves 8 and 12 corresponding one-to-one, and a groove 18 is provided on the edge of the filter plate 6, the groove 18 being located on the bottom surface of the filter plate 6, and the groove 18 communicating with groove 12; Specifically, the inlet pipe 3 at the input end of the water pump 2 draws out the sewage from the bottom of the breeding tank 1 and sends it into the filter device 4 for treatment. The filter device 4 consists of an inlet guide chamber, a pre-filter cartridge, a mechanical filter layer, a biological purification bed, and an outlet return section. The sewage entering the filter device 4 is first guided and evenly distributed in the guide chamber to enter the pre-filter cartridge for interception and initial sedimentation of coarse particles. Then, the remaining water flows through the mechanical filter layer to further remove impurities from medium suspended solids. At the same time, the microorganisms fixed on the surface of the filter layer and the biological purification bed continue to decompose dissolved pollutants such as ammonia nitrogen and nitrite. Finally, the water is discharged uniformly through the outlet return section to ensure that the water body achieves purification through the combined action of mechanical and biological action of particles and dissolved pollutants. The water in the outlet return section is then returned to the breeding tank 1 through the outlet pipe 5.

[0017] Example 2 Based on Embodiment 1, in order to achieve rapid locking of the filter plate 6, a sliding locking structure is proposed in the groove 8. The locking structure is used to lock the filter plate 6. The locking structure includes a spring 9, a top block 10, and a locking block 11. One end of the spring 9 is connected to the inner bottom surface of the groove 8, and the other end of the spring 9 is connected to the bottom surface of the top block 10. The top block 10 slides in the groove 8. The top of the top block 10 has an isosceles trapezoidal structure. A limit block is fixed at the opening of the groove 8. The foot of the top block 10 is limited by the limit block. Two sets of locking blocks 11 are provided, and the two sets of locking blocks 11 are fixed to the inner wall of the groove 12. The two sets of locking blocks 11 are located on the upper and lower surfaces of the groove 12. The locking blocks 11 have a right-angled trapezoidal structure. The hypotenuse of the locking block 11 is connected to the top block 10. The two inclined sides of 10 are in contact. The four corners of the inner wall of the breeding box 1 are all fixed with support plates 7. The filter plate 6 is placed on the upper surface of the support plate 7. The locking structure is unlocked by the push structure. The push structure includes a rotating rod 13, a connecting plate 14 and a protrusion 15. The rotating rod 13 rotates inside the filter plate 6. One end of the rotating rod 13 is located above the filter plate 6, and the other end of the rotating rod 13 is located in the second groove 12. The connecting plate 14 is fixed on the outside of the rotating rod 13, and the protrusion 15 is fixed on the outside of the connecting plate 14. The protrusion 15 has an isosceles trapezoidal cross section. The two sides of the protrusion 15 are arc-shaped. The protrusion 15 is flush with the top block 10. The protrusion 15 is located between the two sets of locking blocks 11. The connecting plate 14 and the protrusion 15 are both located in the second groove 12. Specifically, due to the large amount of impurities in aquaculture water, filter plate 6 needs to be replaced frequently. When installing filter plate 6, first place filter plate 6 on support plate 7, with the top two inclined edges of top block 10 contacting the bottom of filter plate 6. Figure 4 As can be seen, the bottom edge of the filter plate 6 is arc-shaped, which allows the inclined edge of the top block 10 to move upward along the arc edge during the downward movement of the filter plate 6 until it fits against the inner wall of the groove 18. Under the elastic force of the spring 9, the top block 10 slides along the inside of the first groove 8 and gradually enters the groove 18 at the bottom of the filter plate 6 until it moves into the second groove 12. When the top block 10 moves between the two sets of locking blocks 11, the spring 9 returns to its original position, so that the inclined surface of the top block 10 fits against the inclined edges of the two sets of locking blocks 11, thus forming a stable locking state. When it is necessary to disassemble or replace the filter plate 6, the rotating rod 13 is rotated to drive the connecting plate 14 to rotate, so that the outer protrusion 15 rotates accordingly. The arc-shaped edge of the protrusion 15 contacts the top block 10, so that the top block 10 overcomes the elastic force of the spring 9 and moves inward, disengaging from the clamping of the locking block 11, thereby releasing the locking state. The operator can then easily remove the filter plate 6 for cleaning or replacement.

[0018] Example 3 Based on Embodiment 2, in order to achieve stability when disassembling the filter plate 6, it is proposed that the top surface of the filter plate 6 is provided with a slot 17, the slot 17 is located directly above the top block 10, one end of the rotating rod 13 is equipped with a locking rod 16, the locking rod 16 can be inserted into the slot 17, and the locking rod 16 is located directly above the protrusion 15. Specifically, when rotating rod 13, when protrusion 15 abuts against top block 10, according to... Figure 3 and Figure 5 It can be seen that the filter plate 6 has a locking structure at all four corners. When a rotating rod 13 is rotated, the locking rod 16 is moved down and inserted into the locking slot 17, thereby locking the rotating rod 13 and facilitating the operation of the next set of locking structures.

[0019] In use, after the filter plate 6 is placed above the support plate 7, the downward movement of the filter plate 6 causes the top two inclined edges of the top block 10 to disengage from the bottom of the filter plate 6. Due to the arc edge at the bottom of the filter plate 6, the top block 10 can slide along the arc edge into the groove 18. Under the rebound force of the spring 9, the top block 10 slides along the groove 1 8. As the filter plate 6 continues to move, the top block 10 gradually enters the groove 2 12. When the top block 10 moves between the two sets of locking blocks 11, the elastic force generated by the spring 9 causes the inclined edges of the top block 10 to engage with the locking blocks. The inclined edges of block 11 fit tightly together, thereby achieving a snap-in positioning and forming a stable locking state to prevent the filter plate 6 from loosening. When it is necessary to disassemble or replace the filter plate 6 with a different aperture, by rotating the rotating rod 13 inside the filter plate, the connecting plate 14 is driven to rotate synchronously, causing the protrusion 15 installed on the outside of the connecting plate to rotate and press against the side of the top block 10. Under the pushing force of the protrusion 15, the top block 10 overcomes the elastic force of the spring 9 and moves outward, disengaging from the locking state between the snap-in blocks 11, and the filter plate 6 can be easily removed and replaced.

[0020] 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.
