[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] An embodiment of a water circulation and filtering device for aquaculture of bluestone bream of the present invention is as follows: Figures 1 to 10 shown.

[0031] A water circulation filter device for breeding bluestone climbing fish is used to filter the water in the fish pond for breeding bluestone climbing fish, comprising a housing 100, a main filter and a secondary filter, wherein the main filter comprises a filter cartridge 200 and a cleaning mechanism 300, and the filter cartridge 200 is arranged in the housing 100 along a first direction, and the first direction is a horizontal direction. A filter screen is arranged on the filter cartridge 200, and the cleaning mechanism 300 is installed on the housing 100, and is used to clean the filter cartridge 200. The two ends of the filter cartridge 200 along the first direction are respectively referred to as the first end and the second end, the first end is blocked, and the second end is connected in the first direction, the first end is provided with a water inlet 201, the fish pond is provided with an inlet and an outlet, the water inlet 201 is connected with the outlet of the fish pond, and the housing 100 is provided with a water outlet, and the water outlet is connected with the inlet of the fish pond.

[0032] The auxiliary filter element includes an adjustment disk 400, a movable disk 500, a water supply mechanism and a plurality of filter bags 600. The adjustment disk 400 is arranged at the second end of the filter cartridge 200 and is coaxial with the filter cartridge 200. The plurality of filter bags 600 are arranged in the filter cartridge 200 along a first direction, and the two ends of the filter bag 600 along the first direction are respectively referred to as the head end and the tail end. The head end is connected along the first direction, fixedly connected to the adjustment disk 400 and extending out of the adjustment disk 400, and the head end of the filter bag 600 is connected to the inside of the housing 100 in the initial state. The filter bag 600 has a support frame so that one side of the tail end is suspended.

[0033] The movable disk 500 is coaxially arranged with the filter cartridge 200 and can move in the first direction in the housing 100. The movable disk 500 is located on the side of the adjustment disk 400 away from the filter cartridge 200 in the first direction. In the initial state, the movable disk 500 and the adjustment disk 400 are away from each other in the first direction and do not abut against the filter cartridge 200. The movable disk 500 moves in the housing 100 along the first direction toward the side close to the adjustment disk 400 to abut against the filter cartridge 200, and a backwash chamber 700 is defined between the movable disk 500, the adjustment disk 400 and the filter cartridge 200, and at this time, the head end of the filter bag 600 is connected to the backwash chamber 700. The water supply mechanism is installed on the housing 100 for supplying water into the backwash chamber 700.

[0034] This embodiment provides a main filter element and a secondary filter element on the housing 100. When in use, the water to be filtered in the fish pond is fed into the filter cartridge 200 from the water inlet 201. The water will flow from the inside of the filter cartridge 200 to the outside of the filter cartridge 200 for filtration. The filtered water will return to the fish pond through the water outlet on the housing 100. The impurities left after filtration will adhere to the inner wall of the filter cartridge 200. At the same time, the water entering the filter cartridge 200 will also pass through a plurality of filter bags 600, flowing from the outside of the filter bag 600 to the inside of the filter bag 600 for filtration. At this time, the movable disk 500 does not abut against the filter cartridge 200. Therefore, the filtered water will flow from the head end of the filter bag 600 to the housing 100, and then return to the fish pond through the water outlet on the housing 100. The impurities left after filtration will adhere to the outside of the filter bag 600. Although some impurities are carried away to the inner wall of the filter cartridge 200 by the water flow, most of the impurities are still attached to the outer side of the filter bag 600. That is, by arranging a plurality of filter bags 600 in the filter cartridge 200, it does not take up too much space, and prolongs the use time of the water circulation filter device for bluestone climbing fish farming, and reduces the cleaning frequency of the filter cartridge 200.

[0035] When it is necessary to clean the filter cartridge 200 and the filter bag 600, first drive the movable disk 500 to move in the shell 100 along the first direction toward the side close to the adjustment disk 400, so that the movable disk 500 can abut against the filter cartridge 200. At this time, the head end of the filter bag 600 is connected with the recoil chamber 700, and then start the cleaning mechanism 300 and the water supply mechanism. The filter cartridge 200 is cleaned by the cleaning mechanism 300, and water is supplied to the recoil chamber 700 through the water supply mechanism. Water will enter the filter bag 600 from the recoil chamber 700 and recoil the filter bag 600 to prevent the filter bag 600 from being blocked. The backwashing method improves the cleaning effect of the filter bag 600. The impurities after recoil will adhere to the inner side of the filter cartridge 200 and be cleaned together by the cleaning mechanism 300, which saves time and effort while improving the stability of the living environment of the bluestone crawler.

[0036] The movement of the movable plate 500 is used to distinguish between the use and cleaning of the filter bag 600, that is, in normal use, the movable plate 500 does not abut against the filter cartridge 200, and the backflushing chamber 700 is not formed at this time, and the water filtered by the filter bag 600 can flow directly from the tail end of the filter bag 600 into the housing 100. When the filter bag 600 needs to be cleaned, the movable plate 500 is moved to abut against the filter cartridge 200 to form the backflushing chamber 700, and the filter bag 600 is backflushed and cleaned from the backflushing chamber 700. The space between the movable plate 500 and the adjusting plate 400 is used to filter and clean the filter bag 600, respectively, saving space and making it more convenient to use.

[0051] In this embodiment, multiple connecting pieces 432 are provided to improve the uniformity of distribution of the filter bag 600 in water.

[0052] Furthermore, the plurality of connecting pieces 432 are connected by adjusting pieces 433, the adjusting pieces 433 are elastic, and are arranged on the blocking film 430 around the first direction and are slidably matched with the blocking film 430. Both ends of the adjusting piece 433 around the first direction are provided with follower pieces 434, two floating balls 431 are provided, and the two floating balls 431 are arranged one-to-one with the two follower pieces 434, and the floating balls 431 are fixedly connected with the follower pieces 434 arranged correspondingly thereto.

[0053] By setting an adjusting piece 433 to connect multiple connecting pieces 432, when the float 431 moves up and down in the water and drives the blocking membrane 430 to deform, it will drive the corresponding follower piece 434 to move synchronously, and further cause the adjusting piece 433 to deform, thereby maintaining the uniformity of distribution of multiple connecting pieces 432 in the water as much as possible, that is, the uniformity of distribution of the filter bag 600 in the water.

[0054] Furthermore, a plurality of connecting pieces 432 are all located at the lower part of the blocking film 430 and one of the connecting pieces 432 is in a vertical state. The connecting piece 432 is connected to a blocking ball 450 through a first elastic member 440. The first elastic member 440 is arranged along the first direction. The first elastic member 440 is a compression spring. The first elastic member 440 always has a tendency to urge the blocking ball 450 to move away from the blocking film 430 along the first direction. Two pull ropes 460 are fixed to the blocking ball 450. The pull ropes 460 are elastic ropes. The two pull ropes 460 are respectively fixed to the connecting piece 432 arranged adjacent to it around the first direction. The recoil port 510 is coaxially arranged with the blocking ball 450 in the first direction. The recoil port 510 has a large end and a small end. The large end and the small end are arranged in sequence in the first direction, and the large end is located on the side of the small end close to the blocking ball 450 in the first direction.

[0055] A distance sensor is provided in the filter cartridge 200, and the distance sensor is used to detect the height of the liquid level in the filter cartridge 200 in the vertical direction, and when the height of the liquid level in the filter cartridge 200 in the vertical direction is greater than a preset value, the detected electrical signal is fed back to the external controller, and the controller is electrically connected to the motor 130, the hydraulic telescopic cylinder 150, the first water pump, the second water pump 120 and the third water pump 160, and can control the motor 130, the hydraulic telescopic cylinder 150, the first water pump, the second water pump 120 and the third water pump 160 to start or shut down.

[0056] When in use, the first water pump is driven to start by the controller to supply water to the filter cartridge 200. At this time, the distance sensor constantly monitors the height of the liquid level in the filter cartridge 200 in the vertical direction. When the height of the liquid level in the filter cartridge 200 in the vertical direction is greater than a preset value, it means that the filter cartridge 200 is clogged and needs to be cleaned. The distance sensor will feed back a signal to the controller, and the controller stops the first water pump, and starts the hydraulic telescopic cylinder 150, the motor 130, the second water pump 120 and the third water pump 160 to start cleaning.

[0057] In this embodiment, a sealing ball 450 is arranged on the connecting piece 432 in a vertical state. When the filter cartridge 200 and the filter bag 600 are cleaned, as the filter cartridge 200 is gradually unblocked, the height of the liquid level in the filter cartridge 200 in the first direction will continue to decrease, and when the liquid level in the filter cartridge 200 changes, the height of the float 431 in the vertical direction will change accordingly, and drive the connecting piece 432 through the follower piece 434, thereby stretching or contracting the pull rope 460. When the liquid level is relatively high, the float 431 is also relatively high. At this time, the filter cartridge 200 is blocked to a large extent, and the positions of multiple connecting pieces 432 around the first direction are relatively far apart. Therefore, the pulling force of the pull rope 460 on the sealing ball 450 is relatively large, and the effect of the first elastic member 440 on the sealing ball 450 is relatively smaller, that is, when the movable disk 500 abuts against the filter cartridge 200, the sealing ball 450 is closer to the large end side of the backwash port 510 in the first direction, which is more convenient for water to pass through.

[0058] When the liquid level is relatively low, it means that the filter cartridge 200 is gradually unblocked, the float 431 is also relatively low, and the positions of the multiple connecting pieces 432 in the first direction are relatively close. Therefore, the pulling force of the pull rope 460 on the blocking ball 450 is relatively small, and the effect of the first elastic member 440 on the blocking ball 450 is relatively greater. That is, when the movable disk 500 abuts against the filter cartridge 200, the blocking ball 450 is closer to the small end of the recoil port 510 in the first direction, and the opening degree of the recoil port 510 is adjusted by the height of the liquid level in the filter cartridge 200, thereby accelerating the cleaning while saving water.

[0059] In combination with the above embodiments, the specific working process is as follows:

[0060] When in use, the water to be filtered in the fish pond is fed into the filter cartridge 200 from the water inlet 201. The water will flow from the inside of the filter cartridge 200 to the outside of the filter cartridge 200 for filtration. The filtered water will return to the fish pond through the water outlet on the housing 100. The impurities left after filtration will adhere to the inner wall of the filter cartridge 200. At the same time, the water entering the filter cartridge 200 will also pass through a plurality of filter bags 600, and flow from the outside of the filter bag 600 to the inside of the filter bag 600 for filtration. At this time, the movable plate 500 does not abut against the filter cartridge 200. Therefore, the filtered water will flow from the head end of the filter bag 600 to the housing 100, and then return to the fish pond through the water outlet on the housing 100. The impurities left after filtration will adhere to the outer side of the filter bag 600. Although some impurities will be carried away to the inner wall of the filter cartridge 200 under the action of the water flow, most of the impurities will still adhere to the outer side of the filter bag 600.

[0061] When the filter cartridge 200 and the filter bag 600 need to be cleaned, the hydraulic telescopic cylinder 150 is started to allow the movable plate 500 to abut against the filter cartridge 200 . At this time, the head end of the filter bag 600 is connected to the backflushing chamber 700 .

[0062] Then start the motor 130, which will drive the gear 140 to rotate in the first direction, and the gear 140 will drive the gear ring 210 to rotate, and drive the filter cartridge 200 to rotate in the first direction through the gear ring 210. At the same time, start the second water delivery pump 120 to deliver water to the cleaning pipe 310, and the water will be sprayed onto the filter cartridge 200 through the nozzle 311 after passing through the cleaning pipe 310, and the impurities on the inner wall of the filter cartridge 200 will be backwashed, and the washed impurities will fall on the receiving tray 320. In addition, during the rotation of the filter cartridge 200 relative to the receiving tray 320 and the nozzle 311, the cleaning position of the filter cartridge 200 can be continuously changed, and the filter cartridge 200 can be fully cleaned. After the impurities fall on the receiving tray 320, the impurities will be discharged into the collection box 340 through the sewage pipe 330, which is convenient for subsequent unified treatment.

[0063] At the same time, the third water delivery pump 160 is started to supply water into the backflushing chamber 700. The water will enter the filter bag 600 from the backflushing chamber 700 and backflushed the filter bag 600 to prevent the filter bag 600 from being blocked. The backflushing method improves the cleaning effect of the filter bag 600. The impurities after backflushing will adhere to the inner side of the filter cartridge 200 and be cleaned by the cleaning mechanism 300.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
