Description

Technical Field

[0001] The invention relates to the field of zooplankton screening equipment, in particular to a living zooplankton automatic washing and screening device. Background Art

[0002] Zooplankton refers to small animals that float or have very weak swimming ability in the water. There are many types of zooplankton, from low-level tiny protozoa, coelenterates, comb jellies, rotifers, crustaceans, gastropods, etc., to higher-level urochordates. Almost every type has permanent representatives. Among them, copepods are the most prominent, with their numerous species, huge numbers and wide distribution. Zooplankton is the natural food for the larval stage of aquatic animals. Some aquatic animals even feed on zooplankton all their lives. Therefore, artificial cultivation of zooplankton is not only an important technology to support the breeding of aquatic animal seedlings, but also an auxiliary technology necessary for studying the early development of aquatic organisms. At present, the types of zooplankton used in the production of aquatic animal seedlings mainly include small invertebrates such as rotifers, Artemia, cladocerans and copepods.

[0003] When artificially cultivated zooplankton is fed to aquatic animal seedlings, it is necessary to collect it from the zooplankton culture pond, and the collected zooplankton needs to be further screened and flushed. However, the existing screening equipment uses a self-flowing screening method when screening the zooplankton, resulting in low screening efficiency and failure to achieve automatic flushing of the zooplankton during the screening process.

In actual application, the flushing nozzle 410 sprays flushing liquid downward, which can flush the zooplankton on the sub-screens downward so that the zooplankton can fall on the inner bottom surface of each storage chamber.

Through the above-mentioned specific structural design, the lifting drive unit can realize the lifting and lowering drive of the flushing assembly 4, so that the flushing assembly 4 can flush each sub-screen in the up and down direction, and for the zooplankton that remains on the sub-screen and has not been flushed and fallen, the bristles 409 on the outer side of the sleeve 408 can realize brushing the sub-screen.

[0044] The top of the outer shell 1 is provided with a stock solution adding pipeline structure 2 for adding the sub-screening stock solution into the first sub-screen 11 and a flushing liquid input pipeline structure 3 for providing flushing liquid to the flushing component 4.

[0048] Working principle:

[0049] When in use, the stock solution containing the living zooplankton is added into the first storage chamber 14 in the first sub-screen 11 by the stock solution adding pipeline structure 2. When introduced, the stock solution is added into the first storage chamber 14 in turn by the first liquid inlet pipe 2b, the telescopic pipe 2c and the liquid outlet pipe 2d. The digital display control panel 6 controls the motor 8a of the outer diffusion toggle assembly 8 to open. The output shaft of the motor 8a rotates to drive the rotating rod 8b to rotate. The rotating rod 8b rotates to drive the outer toggle blade 8c to rotate. The rotation of the toggle blade 8c can transfer the stock solution in the first storage chamber 14 to the second storage chamber 15, the third storage chamber 16 and the third storage chamber 17 in turn. The liquid flows in the first storage chamber 14, the second storage chamber 15, the third storage chamber 16 and the fourth storage chamber 17. During this process, the first sub-screen 11, the second sub-screen 12 and the third sub-screen 13 are used to screen the zooplankton according to their size. During this process, the flushing liquid input pipeline structure 3 and the flushing component 4 cooperate to flush the zooplankton. The waste liquid generated by the flushing is discharged by the waste liquid discharge pipe 9a of the drainage pipeline structure 9, while the zooplankton remains in each of the first storage chamber 14, the second storage chamber 15, the third storage chamber 16 and the fourth storage chamber 17. At this time, the zooplankton can be discharged by the drainage pipeline structure 9 under the flushing of the flushing component 4.

[0050] When the flushing assembly 4 is flushing, the flushing liquid input pipeline structure 3 can sequentially pass through the second liquid inlet pipe 303, the spring liquid guide pipe 304, the lifting liquid guide pipe 301, the pipe joint 306, the L-shaped liquid guide pipe 308, the annular liquid guide pipe 305, the linear liquid guide pipe 407, the connecting pipe 406, the hanging tube body 402 and the flushing nozzle 410 to spray the cleaning liquid. Furthermore, the push rod of the electric telescopic rod 5 can push the central connecting block 403 up and down, thereby driving the flushing nozzle 410 to move up and down, thereby achieving the cleaning of each sub-screen. For flushing in the downward direction, further, the output shaft of the motor 8a of the outer diffusion toggle assembly 8 rotates, which can drive the rotating rod 8b and the electric telescopic rod 5 to rotate, so that the electric telescopic rod 5 drives the central connecting block 403 to rotate, so as to realize the flushing of each sub-screen in the horizontal circumferential direction. Therefore, with the cooperation of the electric telescopic rod 5 and the outer diffusion toggle assembly 8, the flushing assembly 4 can realize the comprehensive flushing of each sub-screen to avoid the residual zooplankton on each screen, so that the zooplankton can be completely removed by the drainage pipe structure 9 after sub-screening to prevent the occurrence of residue.
