Description

Technical Field

[0001] The present application relates to the technical field of aquaculture equipment, and in particular to a filtering device for aquaculture that is easy to maintain. Background Art

[0002] In aquaculture, the quality of the water within aquaculture tanks plays a crucial role in the growth, health, and survival of aquacultured organisms. With the continuous expansion of aquaculture scale and increasing stocking density, large amounts of impurities such as leftover bait and excrement are generated within the aquaculture tanks. If these impurities are not removed from the water promptly and effectively, they can lead to deterioration of water quality, the growth of harmful microorganisms, and the subsequent disease and even mass mortality of aquacultured organisms, resulting in significant economic losses for aquaculture farmers.

[0003] Chinese utility model patent publication number CN222129083U discloses an easy-to-maintain aquaculture filtration device. It uses a water pump to pump water containing debris from the aquaculture tank through a water pipe, a connecting pipe, and a guide frame into the filter box for filtration. After being filtered through a triple filter frame (third filter frame, second filter frame, and first filter frame), the water becomes cleaner before flowing back into the aquaculture tank, achieving a cyclical water purification process. However, when the third filter rack, the second filter rack and the first filter rack need to be cleaned, they are often manually taken out in turn for cleaning, which is not only relatively cumbersome to operate, but also untimely cleaning will reduce the filtration efficiency and affect the water purification effect. In addition, the water flow of the device is filtered and intercepted in a straight line through the single static third filter rack, the second filter rack and the first filter rack. This filtration method allows the water flow to pass through each layer of the filter along a predetermined path, resulting in uneven contact between the water and the filter, which may easily lead to some areas of the filter rack being overused, while other areas may not be fully utilized, so that some impurities cannot be completely intercepted, thereby reducing the overall filtration efficiency.

[0004] Therefore, the present application provides a filtering device for aquaculture that is easy to maintain to solve the above problems. Summary of the Invention

[0019] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0020] Example 1 This embodiment provides a kind of aquaculture filtration equipment that is easy to maintain, such as Figure 1-Figure 5 As shown, the filtering equipment includes a breeding box 1, a filter box 2 fixedly arranged on the upper side of the breeding box 1, a pumping assembly 3 connected to the breeding box 1 and the filter box 2 respectively for transporting the breeding water in the breeding box 1 to the filter box 2, and a drain pipe 21 fixedly arranged on the side of the filter box 2 away from the pumping assembly 3 for discharging the filtered water into the breeding box 1; the filtering equipment also includes a filter cylinder 4 rotatably connected to the filter box 2 and communicated with the pumping assembly 3 for filtering the breeding water, a driving assembly 5 fixedly arranged on the filter box 2 for driving the filter cylinder 4 to rotate, a spray pipe 6 fixedly arranged in the filter box 2 at a position above the corresponding filter cylinder 4 for backwashing the filter cylinder 4, and a discharge trough 7 fixedly installed in the filter cylinder 4 at a position below the corresponding spray pipe 6 and sequentially passing through the filter box 2 and the breeding box 1 for receiving impurities backwashed by the filter cylinder 4 and discharging them to the outside of the breeding box 1, and the discharge trough 7 is fixed on the filter box 2 and the breeding box 1.

[0021] During use, during the breeding period, the pumping component 3 can be started to squeeze and suck the breeding water in the breeding box 1 into the filter cylinder 4 in the filter box 2. Since the driving component 5 drives the filter cylinder 4 to rotate, as the filter cylinder 4 rotates, it will allow the incoming breeding water to contact the filter holes on the filter cylinder 4 more evenly, so that impurities are intercepted by the filter holes, and the water is filtered through the filter holes and falls into the filter box 2. The filtered water in the filter box 2 will be discharged back into the breeding box 1 through the drain pipe 21, forming a water flow circulation, providing a continuous water source for the breeding organisms. However, impurities attached to the inner wall of the filter cylinder 4 can rotate with the filter cylinder 4 to the bottom of the spray pipe 6 and above the discharge trough 7. The water sprayed by the spray pipe 6 can backwash the attached impurities and drop them into the discharge trough 7. Since there is an inclined surface 71 inclined toward one end outside the breeding box 1 in the discharge trough 7, the impurities washed down will be discharged to the outside of the breeding box 1 along the inclined surface 71 of the discharge trough 7 under the action of gravity, and no manual cleaning is required.

[0022] Among them, in order to ensure the discharge of impurities, the discharge trough 7 has a slope 71 inclined toward the outer end of the breeding box 1; the design of the slope 71 allows the impurities generated by backwashing to move more smoothly along the slope 71 toward the outer end of the breeding box 1 under the action of gravity and be discharged, ensuring the effective discharge of impurities, avoiding the residue and accumulation of impurities in the discharge trough 7, ensuring the smooth flow of the discharge trough 7, further improving the stability and filtering effect of the equipment, and reducing the damage to the equipment caused by residual impurities.

[0023] Specifically, the pumping assembly 3 includes a water pump 32 disposed outside the aquaculture box 1, a water inlet pipe 31 having two ends fixedly connected to one side of the bottom of the aquaculture box 1 and one end of the water pump 32, and a delivery pipe 33 having two ends fixedly connected to the side of the filter box 2 away from the drain pipe 21 and the other end of the water pump 32. The end of the delivery pipe 33 close to the filter box 2 extends into the filter pore cylinder 4. During the breeding period, when the water pump 32 on the pumping assembly 3 is started, the water pump 32 begins to generate suction and pressure difference to provide power for the water pumping process. Since one end of the water inlet pipe 31 is connected to one side of the bottom of the breeding box 1, the suction generated by the water pump 32 through the water inlet pipe 31 will suck the breeding water at the bottom of the breeding box 1 into the water inlet pipe 31, and the other end of the water inlet pipe 31 is fixedly connected to one end of the water pump 32. Then, the breeding water will enter the water pump 32 through the water inlet pipe 31, and then the water pump 32 will start to pump water. 2 will pressurize the incoming aquaculture water, so that the aquaculture water flows from the water pump 32 into the delivery pipe 33. Since the other end of the delivery pipe 33 is connected to the side of the filter box 2 away from the drain pipe 21, and the end of the delivery pipe 33 close to the filter box 2 extends into the filter cartridge 4, the aquaculture water flows in the delivery pipe 33 and finally enters the filter cartridge 4 through the delivery pipe 33, thereby providing a water source for the filter cartridge 4 to filter the aquaculture water, so that the aquaculture water can directly enter the filter cartridge 4 for filtration.

[0024] Furthermore, the drive assembly 5 includes a gear ring 51 fixedly sleeved on the outer side of the end of the filter tube 4 close to the delivery pipe 33, a drive shaft 53 that passes through the filter box 2 and is rotatably connected to the filter box 2 at a position above the corresponding gear ring 51, a drive gear 52 fixedly sleeved on the drive shaft 53 and meshing with the gear ring 51, a fixed box 54 fixedly installed on the outside of the filter box 2 on the side corresponding to the delivery pipe 33, and a drive motor 55 fixedly installed in the fixed box 54 for driving the drive shaft 53 to rotate; When the drive motor 55 on the drive assembly 5 is started, the drive motor 55 will drive the drive shaft 53 connected to it to rotate. Since the drive shaft 53 is connected to the drive gear 52, and the drive gear 52 is engaged with the gear ring 51 on the outside of the filter cylinder 4, when the drive shaft 53 rotates, the drive gear 52 and the gear ring 51 also rotate accordingly. Since the gear ring 51 is fixedly connected to the filter cylinder 4, the rotation of the gear ring 51 will drive the filter cylinder 4 to rotate synchronously. Therefore, when the filter cylinder 4 rotates, the aquaculture water entering the filter cylinder 4 can contact the filter holes of the filter cylinder 4 more evenly with the rotation of the filter cylinder 4, and thus be filtered through the filter holes, thereby avoiding the situation where some areas of the filter holes are overused and other areas are underused, thereby improving the impurity retention effect and filtration efficiency.

[0025] Furthermore, the drive assembly 5 also includes a transmission assembly 56 provided on the drive shaft 53 and connected to the spray pipe 6 and the filter box 2 for transporting the filtered water in the filter box 2 to the spray pipe 6; the transmission assembly 56 includes a connecting gear 561 provided in the fixed box 54 and fixedly sleeved on the drive shaft 53, a transmission shaft 563 rotatably connected to one side of the corresponding connecting gear 561 in the fixed box 54, a transmission gear 562 fixedly sleeved on the transmission shaft 563 and meshing with the connecting gear 561, a runner 564 fixedly connected to one end of the transmission shaft 563 close to the transmission gear 562, and an eccentric gear 564 fixedly installed on the side of the runner 564 away from the transmission shaft 563 and eccentrically arranged. The invention also comprises a first embodiment of the present invention and a second embodiment of the present invention, wherein the first embodiment comprises a first embodiment of the present invention and a second embodiment of the present invention. The first embodiment comprises a first embodiment of the present invention and a second embodiment of the present invention. The first embodiment comprises a first embodiment of the present invention and a second embodiment of the present invention. The first embodiment comprises a first embodiment of the present invention and a second embodiment of the present invention. When the driving motor 55 is started to drive the driving shaft 53 to rotate, and the internal friction of the driving gear 52 and the gear ring 51 drives the filter cylinder 4 to rotate, and the rotation of the filter cylinder 4 is used to rotationally filter the aquaculture water transported by the pumping assembly 3. Since the driving shaft 53 is connected to the connecting gear 561, and the connecting gear 561 is meshed with the transmission gear 562 connected to the transmission shaft 563, when the driving shaft 53 rotates, the transmission shaft 563 can rotate synchronously through the meshing action of the connecting gear 561 and the transmission gear 562. When the transmission shaft 563 rotates, the runner 564 connected thereto will also rotate synchronously. The eccentric shaft is fixedly mounted on the side of the runner 564 away from the transmission shaft 563 and is eccentrically arranged. Therefore, when the runner 564 rotates, the eccentric shaft will perform eccentric circular motion with the rotation of the runner 564. When the eccentric shaft performs eccentric circular motion, it will drive this end of the connecting rod 565 to perform corresponding reciprocating circular motion, which is in turn caused by The other end of the connecting rod 565 is rotatably connected to the push rod 566, and the push rod 566 is slidably connected to the cylinder 567 and fixedly connected to the piston 568. Then, driven by the connecting rod 565, the push rod 566 drives the piston 568 to do reciprocating longitudinal motion in the cylinder 567. When the push rod 566 pushes the piston 568 to move downward, the volume in the cylinder 567 becomes larger, the pressure is reduced, and negative pressure is generated. At this time, the filtered water in the filter box 2 will be sucked out through the suction pipe 569 The filter element 561 is pressed into the cylinder 567, and then, when the piston 568 moves upward, the water in the cylinder 567 is compressed and the pressure increases, so that the filtered water in the cylinder 567 can be pressed into the spray pipe 6 through the connecting pipe 5610. After the filtered water pressed from the cylinder 567 enters the spray pipe 6, the spray pipe 6 will spray the water on the filter cylinder 4 to realize the backwash operation of the filter cylinder 4, thereby timely removing impurities attached to the filter cylinder 4 and maintaining the filtering performance of the filter cylinder 4.

[0026] It should be added that a one-way valve is provided in the suction pipe 569 and the connecting pipe 5610, so that when the suction pipe 569 is used to suck water, the water in the connecting pipe 5610 will not flow back, and when the connecting pipe 5610 is used to transport water, the suction pipe 569 will not flow back, and the connecting gear 561 and the transmission gear 562 are a combination of a large gear and a small gear, which can realize speed-increasing transmission, ensure the reciprocating speed of the piston 568 is fast, so that the spray pipe 6 has enough spray water.

[0027] Example 2 Different from Example 1, Figure 6-Figure 7 As shown, in order to further improve the filtering effect of filtered water, the filtering equipment also includes a purification component 8 arranged in the breeding box 1 and connected to the end of the drain pipe 21 away from the filter box 2 for further purifying the filtered water; the setting of the purification component 8 enables the filtered water to be further purified and returned to the breeding box 1, thereby improving the water quality.

[0028] Furthermore, the purification assembly 8 includes a fixed base 81 fixedly installed in the breeding box 1, a rotating shaft 82 rotatably connected to the fixed base 81, a rotating motor 83 fixedly installed in the fixed base 81 for driving the rotating shaft 82 to rotate, a receiving chamber 84 for placing activated carbon provided inside the top end of the rotating shaft 82 and connected to the drain pipe 21, and an annularly distributed inclined hole 85 provided on the outside of the top end of the rotating shaft 82, the inclined hole 85 being connected to the receiving chamber 84, and the top end of the rotating shaft 82 being rotatably connected to the end of the drain pipe 21 away from the filter box 2; When the aquaculture water in the aquaculture box 1 is filtered by the rotating filter cylinder 4 and the filtered water in the filter box 2 is discharged into the aquaculture box 1 through the drain pipe 21, the rotating motor 83 can be started to drive the rotating shaft 82 to rotate. Since the drain pipe 21 is connected to the accommodating chamber 84 set in the rotating shaft 82, the filtered water discharged through the drain pipe 21 will flow directly into the accommodating chamber 84 and contact the activated carbon in the accommodating chamber 84. Since the activated carbon has an adsorption effect, it can remove odor, harmful substances and some microorganisms in the filtered water, and it can further purify the filtered water. However, as the rotating shaft 82 rotates, the filtered water in the accommodating chamber 84 can flow out evenly through the inclined holes 85 arranged in a ring shape and opened on the outside of the top of the rotating shaft 82 under the action of centrifugal force and gravity, and then return to the aquaculture box 1.

[0029] It should be noted that a snap-fit ​​cover is provided on both sides of the top of the rotating shaft 82 corresponding to the drain pipe 21 , and activated carbon can be added or replaced into the accommodating chamber 84 by opening the cover.

[0030] In addition, in order to reduce the precipitation of impurities inside the breeding box 1, a stirring blade 86 for stirring the breeding water at the bottom end of the breeding box 1 is fixedly sleeved on the outer side of the bottom end of the rotating shaft 82; the design of the stirring blade 86 can stir the breeding water at the bottom end of the breeding box 1 as the rotating shaft 82 rotates, thereby reducing the precipitation of impurities inside the breeding box 1 and avoiding the accumulation of impurities at the bottom of the breeding box 1, which affects the living environment of the cultured organisms.

[0031] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
