[0001] The present application relates to the technical field of separation equipment, and in particular to an aquatic organism sampling and separation device. Background Art

[0002] The growth of aquatic organisms is not only affected by weather and region, but the most direct factor affecting it is water quality. Different aquatic organisms require different water quality for growth. Therefore, before breeding aquatic organisms, it is necessary to raise aquatic organisms in different water qualities and sample and compare them. The size of the individual aquatic organisms can indirectly reflect whether the aquatic organisms are suitable for growing in this water quality. After sampling, the aquatic organisms need to be sorted, and the aquatic organisms of relative size must be separated and the data calculated for relative comparison.

Therefore, the aquatic organisms need to be cleaned again after screening, and the screening part may be blocked by the entanglements and affect the screening of the aquatic organisms, thereby affecting the screening efficiency of the aquatic organisms, so improvement is needed.

[0017] The following is combined with Figure 1-9 This application is described in further detail.

[0018] The present application discloses an aquatic organism sampling and separation device. Figure 1 and Figure 2 As shown, the aquatic organism sampling and separation device comprises a vertically arranged sieve barrel 1, the top of the sieve barrel 1 is connected to a feed pipe 11, and the bottom of the sieve barrel 1 is connected to a discharge pipe 12; two filter discs 13 arranged at intervals from top to bottom are fixedly embedded in the sieve barrel 1, and the filter hole diameter of the filter disc 13 located on the upper side is larger than the filter hole diameter of the filter disc 13 located on the lower side. When the water body with aquatic organisms enters the sieve barrel 1 through the feed pipe 11, the two filter discs 13 will filter and separate the water body, and the large-volume aquatic organisms will accumulate on the upper surface of the upper filter disc 13, and the small-volume aquatic organisms will accumulate on the upper surface of the lower filter disc 13, and the water body mixed with fine impurities will be discharged through the discharge pipe 12.

[0019] like Figure 2 and Figure 3 As shown, the height of the upper surface of the filter disc 13 gradually decreases from its edge to its center, so that the aquatic organisms accumulated on the upper surface of the filter disc 13 gather toward the center of the filter disc 13 for subsequent cleaning of the aquatic organisms.

[0020] A stirring unit 2 is provided on the upper side of each filter disc 13. The stirring unit 2 includes a first motor 21 installed on the outer wall of the sieve barrel 1. The output shaft of the first motor 21 is coaxially connected with an inclined stirring paddle 22. The stirring paddle 22 is located inside the sieve barrel 1, and there is a gap between the stirring paddle 22 and the upper surface of the filter disc 13. During the separation of aquatic organisms, the first motor 21 will drive the stirring paddle 22 to rotate. The stirring paddle 22 will rotate and stir the water body with aquatic organisms, so that the aquatic organisms are separated from the entangled objects, and the water body on the upper side of the filter disc 13 is in a constant stirring state to prevent the aquatic organisms and the entangled objects from clogging the filter disc 13; and the stirring paddle 22 is provided with multiple blades in the axial and circumferential directions. The entangled objects are easily entangled on the blades of the stirring paddle 22 during the stirring process, so that the separated aquatic organisms and the entangled objects are not easy to be entangled again.

[0021] It is worth noting that at least two groups of stirring units 2 are provided on the upper side of each filter disc 13 and are circumferentially arranged around the axis of the filter disc 13, so that there are at least two vortices with different rotation directions on the upper side of each filter disc 13. The vortices will collide with each other and form mixed flows, further facilitating the separation of aquatic organisms and entangled objects.

[0022] A discharge port 131 is provided at the center of the filter disc 13, and a diverter unit 3 is provided at the discharge port 131. The diverter unit 3 has two channels and can control the opening and closing of the two channels; the diverter unit 3 includes a guide pipe 31 connected to the discharge port 131, and a discharge pipe 32 and a debris discharge pipe 34 are connected to the guide pipe 31. The discharge pipe 32 is the first channel, and the debris discharge pipe 34 is the second channel. One end of the discharge pipe 32 and the debris discharge pipe 34 away from the guide pipe 31 extends out of the screen barrel 1, and a first solenoid valve 33 is installed on the discharge pipe 32, and a second solenoid valve 35 is installed on the debris discharge pipe 34.

[0023] While water containing aquatic organisms continues to enter the screen barrel 1, the first solenoid valve 33 and the second solenoid valve 35 are both in a closed state; when water no longer enters and the water above the filter disc 13 is drained, the first solenoid valve 33 will open, and the aquatic organisms gathered at the discharge port 131 will be discharged through the guide pipe 31 and the discharge pipe 32.

[0024] like Figure 3 and Figure 4 As shown, it also includes a cleaning unit 4, which includes a second motor 41 installed at the bottom of the screen barrel 1, and a rotating shaft 42 is coaxially connected to the output shaft of the second motor 41. The rotating shaft 42 is coaxially arranged with the filter disc 13 and rotatably penetrates the material guide pipe 31. A sealing plate 45 is installed on the inner wall of the material guide pipe 31, and a rotating plate 43 that can rotatably abut against the upper surface of the sealing plate 45 is installed on the rotating shaft 42, and a scraper 44 that abuts against the upper surface of the filter disc 13 is installed on the rotating plate 43.

[0025] During the process of filtering and separating aquatic organisms by the sieve plate, the second motor 41 will be in a closed state, and the rotating plate 43 and the sealing plate 45 will jointly seal the upper end opening of the guide tube 31; when the first solenoid valve 33 is opened, the second motor 41 will also be started, and the second motor 41 will drive the rotating plate 43 and the scraper 44 to rotate through the rotating shaft 42, and the scraper 44 will slowly rotate and scrape the aquatic organisms accumulated on the upper surface of the filter plate 13. Under the action of their own gravity, the aquatic organisms will tilt and slide downward to the discharge port 131, thereby preventing the aquatic organisms from remaining on the upper surface of the filter plate 13; during the rotation process, the rotating plate 43 will cause the upper end opening of the guide tube 31 to be intermittently opened, so that the aquatic organisms that move to the discharge port 131 can be discharged through the guide tube 31 and the discharge tube 32.

[0026] It is worth mentioning that the upper surface of the rotating plate 43 is inclined, so that aquatic organisms are not easy to accumulate on the upper surface of the rotating plate 43; and the rotating plate 43 will continue to contact the upper surface of the sealing plate 45 during the rotation process, so that the aquatic organisms accumulated on the upper surface of the sealing plate 45 will also be pushed by the rotating plate 43 into the guide tube 31 for discharge, thereby avoiding the residue of aquatic organisms in the screen barrel 1.

[0027] like Figure 2 and Figure 3 As shown, the control unit 5 is also included. The control unit 5 includes a flow sensor 52 and a controller 51. The flow sensor 52 is installed on the feed pipe 11, and the controller 51 is installed on the screen barrel 1. The flow sensor 52 and the first motor 21 are both coupled to the controller 51. When the water body with aquatic organisms enters the screen barrel 1 through the feed pipe 11, the flow sensor 52 will detect that there is liquid flowing in the feed pipe 11, and the flow sensor 52 will send a separation signal to the controller 51. The controller 51 will control the first motor 21 to start, and the first motor 21 will drive the stirring paddle 22 to rotate and stir the water body; that is, when the water body enters the screen barrel 1, the first motor 21 will start automatically, so that the stirring paddle 22 stirs the water body, and the automatic separation of the aquatic organisms and the entangled objects is realized.

[0028] When water no longer enters the screen barrel 1 through the feed pipe 11, the flow sensor 52 will detect that there is no liquid flowing in the feed pipe 11, and the flow sensor 52 will transmit a cleaning signal to the controller 51, and the controller 51 will control the first motor 21 to turn off after waiting for a specified time; in this embodiment, the controller 51 controls the first motor 21 to turn off after timing for 10 seconds. At this time, the water in the screen barrel 1 has been basically completely discharged, and the first motor 21 is automatically turned off in time, thereby saving energy.

[0029] It is worth noting that the second motor 41 is coupled to the controller 51. When the controller 51 controls the first motor 21 to turn off, the controller 51 will also control the second motor 41 to turn on; that is, when the water in the screen barrel 1 is basically emptied, the aquatic organisms on the upper surface of the filter disc 13 will be automatically discharged through the discharge pipe 32.

[0030] like Figures 5 to 7 As shown, it also includes a flushing unit 6 and a driving unit 7. The flushing unit 6 includes a high-pressure water pump 61 installed on the outer side wall of the screen barrel 1. The high-pressure water pump 61 is connected to a plurality of water spray shells 63 through a hose 62. The water spray shells 63 correspond to the stirring paddles 22 one by one. A mounting plate 16 is fixedly connected to the screen barrel 1. The driving unit 7 includes a roller 71 rotatably connected to the mounting plate 16. The roller 71 and the mounting plate 16 are commonly fixedly connected with the same first torsion spring 72, that is, one end of the first torsion spring 72 is fixedly connected to the roller 71, and the other end of the first torsion spring 72 is fixedly connected to the mounting plate 16. The water spray shell 63 is connected to the roller 71 through a pull rope 73, and the water spray shell 63 is connected to the screen barrel 1 through an elastic telescopic rod 64. The screen barrel 1 is rotatably connected with a plurality of guide wheels 74 for the pull rope 73 to bypass.

[0031] During the process of aquatic organisms being discharged through the discharge pipe 32, the first torsion spring 72 and the elastic telescopic rod 64 will be in a natural state, the pull rope 73 will be in a taut state, and the water spray shell 63 will be at the lower end of the stirring paddle 22; when all the aquatic organisms are discharged, the first solenoid valve 33 will be closed, and the second solenoid valve 35 will be opened, and the roller 71 can be rotated to reel in the pull rope 73, and the pull rope 73 will pull the water spray shell 63 from the lower end of the stirring paddle 22 to the higher end of the stirring paddle 22; during the process of the water spray shell 63 being pulled, the high-pressure water pump 61 will be turned on and supply water to the water spray shell 63 through the hose 62, and the water spray shell 63 will spray high-pressure water onto the stirring paddle 22, so that the entangled materials wrapped around the stirring paddle 22 are washed off, and the entangled materials will be discharged with the water through the guide pipe 31 and the debris discharge pipe 34, thereby realizing the rapid collection of the entangled materials.

[0032] When the roller 71 is no longer subjected to the rotational force, the first torsion spring 72 will return to its natural state and cause the roller 71 to rotate and reset. The roller 71 will loosen the pull rope 73, and the elastic telescopic rod 64 will also return to its natural state, causing the water spray shell 63 to move and reset. The water spray shell 63 will move from the high end of the stirring paddle 22 to the low end of the stirring paddle 22, that is, the water spray shell 63 performs a back and forth high-pressure flushing on the stirring paddle 22, thereby improving the cleaning effect of the entangled objects.

[0033] It is worth noting that the water spray shell 63 is arranged in an arc shape and surrounds the top and left and right sides of the stirring paddle 22, so that all parts of the stirring paddle 22 can be directly flushed by the water spray shell 63 at high pressure, thereby further improving the cleaning effect of the entangled objects.

[0034] like Figures 7 to 9 As shown, a first gear 46 is fixedly sleeved on the output shaft of the second motor 41, a second gear 8 is meshed on the first gear 46, a diameter of the second gear 8 is larger than that of the first gear 46, the second gear 8 is rotatably connected to the sieve barrel 1 through a first vertical shaft 81, a power supply 82 and a power supply block 83 are installed on the lower surface of the second gear 8, a first conductive block 14 and a second conductive block 15 are fixedly connected to the mounting plate 16 through a vertically arranged connecting rod, the first conductive block 14 is connected to the first solenoid valve 33 through a wire, and the second conductive block 15 is connected to the second solenoid valve 35 and the high-pressure water pump 61 through a wire.

[0035] When the second motor 41 is turned on, the second motor 41 will drive the rotating plate 43 and the scraper 44 to rotate through the rotating shaft 42. The second motor 41 will also drive the second gear 8 to rotate through the first gear 46. The second gear 8 will drive the power supply block 83 to rotate in turn to contact the first conductive block 14 and the second conductive block 15.

[0036] In this embodiment, after the second motor 41 is turned on, the power supply block 83 will immediately contact the first conductive block 14. At this time, the power supply 82 will supply power to the first solenoid valve 33 through the power supply block 83 and the first conductive block 14. After the first solenoid valve 33 is energized, it will be in an open state, so that the aquatic organisms on the upper surface of the filter disc 13 can be discharged through the guide pipe 31 and the discharge pipe 32; when the power supply block 83 rotates and disengages from the first conductive block 14, the first solenoid valve 33 will lose power and close, and all the aquatic organisms on the upper surface of the filter disc 13 have been discharged through the discharge pipe 32. At this time, the power supply block 83 will immediately contact the second conductive block 15, and the power supply 82 will supply power to the second solenoid valve 35 and the high-pressure water pump 61 through the power supply block 83 and the second conductive block 15. The second solenoid valve 35 will be in an open state after being energized, and the entangled materials washed off will be discharged from the drainage pipe 34 along with the water. When the power supply block 83 rotates and separates from the second conductive block 15, the second solenoid valve 35 and the high-pressure water pump 61 will lose power and close. At this time, all the entangled materials have been discharged through the drainage pipe 34, and the water spray shell 63 has also completed a back-and-forth high-pressure flushing.

[0037] It is worth mentioning that after controlling the second motor 41 to turn on, the controller 51 will make the second motor 41 only turn on for a specified period of time. During the opening process of the second motor 41, the second gear 8 will only rotate one full circle. Then, the controller 51 will automatically control the second motor 41 to turn off after the timing ends. That is, during the opening process of the second motor 41, the first solenoid valve 33 and the second solenoid valve 35 are only opened once in sequence, thereby completing the one-time classification and collection of aquatic organisms and entanglements of different specifications.

[0038] An arc-shaped rack 84 is installed on the lower surface of the second gear 8, and a third gear 85 is meshed on the rack 84. The third gear 85 is rotatably connected to the mounting plate 16 through a second vertical shaft 86. A first pulley 75 is fixedly sleeved on the second vertical shaft 86, and a second pulley 76 is fixedly sleeved on the winding roller 71. The first pulley 75 and the second pulley 76 are movably sleeved with the same belt 77, so that the winding roller 71 and the second vertical shaft 86 can rotate synchronously; the second vertical shaft 86 and the mounting plate 16 are jointly fixedly connected with the same second torsion spring 87, that is, one end of the second torsion spring 87 is fixedly connected to the second vertical shaft 86, and the other end of the second torsion spring 87 is fixedly connected to the mounting plate 16.

[0039] When the second gear 8 drives the power supply block 83 to rotate and contact the second conductive block 15, the second solenoid valve 35 will be opened, and the high-pressure water pump 61 will perform high-pressure flushing on the stirring paddle 22 through the water spray shell 63; the second gear 8 will also drive the rack 84 to engage with the third gear 85, and the third gear 85 will drive the roller 71 to rotate and reel in the pull rope 73 through the second vertical shaft 86. The pull rope 73 will pull the water spray shell 63 from the lower end of the stirring paddle 22 to the higher end of the stirring paddle 22, so that the water spray shell 63 automatically performs a comprehensive high-pressure flushing on the stirring paddle 22. At this time, the elastic telescopic rod 64, the first torsion spring 72 and the second torsion spring 87 will be in a deformed state.

[0040] When the power supply block 83 moves to the middle of the second conductive block 15, the rack 84 will be disengaged from the third gear 85. At this time, the second solenoid valve 35 and the high-pressure water pump 61 are still in the energized state, and the elastic telescopic rod 64 will return to the natural state and make the water spray shell 63 move and reset to the lower end of the stirring paddle 22, so that the water spray shell 63 completes the back and forth high-pressure flushing of the stirring paddle 22; the first torsion spring 72 will return to the natural state and make the roller 71 rotate and reset, so that the roller 71 will not limit the movement and reset of the water spray shell 63 through the pull rope 73; the second torsion spring 87 will return to the natural state and make the third gear 85 rotate and reset, so that the third gear 85 will not limit the rotation and reset of the roller 71 through the belt drive.

[0041] It is worth noting that, when the water spray shell 63, the roller 71 and the third gear 85 are reset, the second gear 8 has also rotated a full circle, and the second motor 41 will also be controlled to be turned off by the controller 51, and the entire separation process of the aquatic organisms has been completed.

[0042] The implementation principle of the aquatic organism sampling and separation device in the embodiment of the present application is as follows: during the separation process of aquatic organisms, water containing aquatic organisms will enter the screen barrel 1 through the feed pipe 11. At this time, the flow sensor 52 will detect that there is liquid flowing in the feed pipe 11, and the flow sensor 52 will transmit a separation signal to the controller 51. The controller 51 will control the first motor 21 to start, and the first motor 21 will drive the stirring paddle 22 to rotate and stir the water, so that the aquatic organisms are separated from the entangled objects. The separated entangled objects will be entangled on the blades of the stirring paddle 22, and large-volume aquatic organisms will accumulate on the upper surface of the upper filter disc 13, and small-volume aquatic organisms will accumulate on the upper surface of the lower filter disc 13. The water mixed with fine impurities will be discharged through the discharge pipe 12.

[0043] When the water no longer enters the screen barrel 1 through the feed pipe 11, the flow sensor 52 will detect that there is no liquid flowing in the feed pipe 11, and the flow sensor 52 will send a cleaning signal to the controller 51. After timing 10s, the controller 51 will control the first motor 21 to turn off and the second motor 41 to turn on. At this time, the water in the screen barrel 1 has been basically completely discharged, and the second motor 41 will drive the rotating plate 43 and the scraper 44 to rotate through the rotating shaft 42. The scraper 44 will slowly rotate and scrape the aquatic organisms accumulated on the upper surface of the filter disc 13. The aquatic organisms will tilt downward and slide into the guide pipe 31 under the action of their own gravity; the second motor 41 will also drive the second gear 8 to rotate through the first gear 46, and the second gear 8 will drive the power supply block 83 to rotate and contact the first conductive block 14. At this time, the power supply 82 will supply power to the first solenoid valve 33 through the power supply block 83 and the first conductive block 14. After the first solenoid valve 33 is energized, it will be in an open state, so that the aquatic organisms in the guide pipe 31 are discharged through the guide pipe 31 and the discharge pipe 32.

[0044] When the power supply block 83 rotates and disengages from the first conductive block 14, the first solenoid valve 33 will lose power and close, and all the aquatic organisms on the upper surface of the filter disc 13 have been discharged through the discharge pipe 32. At this time, the power supply block 83 will abut against the second conductive block 15, and the power supply 82 will supply power to the second solenoid valve 35 and the high-pressure water pump 61 through the power supply block 83 and the second conductive block 15. The second solenoid valve 35 will be in an open state after being energized, and the high-pressure water pump 61 will supply water to the water spray shell 63 through the hose 62. The water spray shell 63 will spray high-pressure water to the stirring paddle 22, so that the entangled materials wrapped around the stirring paddle 22 are washed off, and the entangled materials will be discharged with the water through the guide pipe 31 and the impurity discharge pipe 34.

[0045] When the power supply block 83 contacts the second conductive block 15, the second gear 8 will drive the rack 84 to engage with the third gear 85, and the third gear 85 will drive the roller 71 to rotate and reel in the pull rope 73 through the second vertical shaft 86. The pull rope 73 will pull the water spray shell 63 from the lower end of the stirring paddle 22 to the higher end of the stirring paddle 22, so that the water spray shell 63 automatically performs a comprehensive high-pressure flushing on the stirring paddle 22.

[0046] When the power supply block 83 moves to the middle of the second conductive block 15, the rack 84 will be disengaged from the third gear 85. At this time, the second solenoid valve 35 and the high-pressure water pump 61 are still in the energized state, the elastic telescopic rod 64 will return to the natural state and make the water spray shell 63 move back and forth to the lower end of the stirring paddle 22, so that the water spray shell 63 completes the back and forth high-pressure flushing of the stirring paddle 22, the first torsion spring 72 will return to the natural state and make the roller 71 rotate and reset, the second torsion spring 87 will return to the natural state and make the third gear 85 rotate and reset, at this time, the power supply block 83 will rotate and disengage from the second conductive block 15, the second solenoid valve 35 and the high-pressure water pump 61 will lose power and close, the windings have all been discharged through the exhaust pipe 34, and the second motor 41 has also been turned on for a specified period of time and is controlled to be closed by the controller 51.

[0047] In summary, in the process of separating aquatic organisms, the present application can automatically and quickly complete the separation and collection of aquatic organisms of different sizes and entanglements, thereby improving the separation efficiency of aquatic organisms.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
