Embodiment 1

[0030] like figure 1 and 2 As shown, a continuous separation device for Artemia nauplii comprises a separation tank 1, a liquid discharge pipe 2, a collection pipe 3, a total liquid inlet pipe 4, a liquid separation pipe 5, an inflatable part 12 and a cleaning device;

[0031] There are two separation tanks 1, which are arranged symmetrically. The separation tank 1 includes a cylindrical tank body 6 made of non-metallic insulating material. The electromagnetic board 7 is connected with an external control system, and the control system controls its power-on and power-off. When it is powered on, it is magnetized, and when it is powered off, it is demagnetized. There are a plurality of through holes 8 evenly distributed on the electromagnetic board 7. The apertures of the through holes 8 are larger than those of artemia. The width of larvae, artemia nauplii can pass through hole 8, and the egg shell with magnetism is then adsorbed on the electromagnetic plate 7; The area surro...

Embodiment 2

[0037] On the basis of Example 1, different from Example 1, such as image 3 As shown, the electromagnetic plate 7 provided inside the tank body 6 is a multi-layer structure, and the cylindrical inner diameters surrounded by each layer of the electromagnetic plate 7 of the multi-layer structure are different, and are all concentrically arranged; the liquid pipe 5 and the innermost layer The area surrounded by the electromagnetic plates 7 is connected, that is, the separation tank 1 can realize multi-stage separation, and the inner ring electromagnetic plates 7 with the smallest inner diameter are separated layer by layer to the outer ring, and the separation effect will be better.

[0038] The working process of the artemia nauplii continuous separation device described in embodiment 1 of the present invention is as follows:

[0039] Open the valve on the main liquid inlet pipe 4 and the liquid separation pipe 5 corresponding to the left separation tank 1, and the mixed soluti...

Abstract

The invention provides a continuous separation device for artemia nauplii. The continuous separation device comprises a plurality of separation tanks, liquid discharge pipes, collecting pipes, a mainliquid inlet pipe and a plurality of liquid distribution pipes and is characterized in that each separation tank comprises a tank body, a cylindrical electromagnetic plate is arranged in the tank body, the electromagnetic plate is provided with a plurality of through holes whose diameters are larger than the width of the artemia nauplii, the bottom of the tank body is provided with a first outletlocated in an area formed by the electromagnetic plate in an enclosed manner, a second outlet and a third outlet are formed in the areas formed by the inner wall of the tank body and the electromagnetic plate in an enclosed manner, the first outlet and the second outlet are connected with the liquid discharge pipes, the third outlet is connected with one collecting pipe, and valves are arranged atthe connections of the outlets and the liquid discharge pipes and the connection of the third outlet and the corresponding collecting pipe; the liquid distribution pipes are in one-to-one correspondence to the separation tanks, one ends of the liquid distribution pipes are connected with the main liquid inlet pipe, and the other ends of liquid separation pipes are communicated with the areas formed by the electromagnetic plates in an enclosed manner; valves are arranged on the main liquid inlet pipe and the liquid distribution pipes. The continuous separation device is specially designed forthe separation of hatched magnetic artemia eggs and is capable achieving continuous and efficient separation.

Description

technical field [0001] The invention belongs to the technical field of artemia nauplius separation, and in particular relates to a continuous separation device for artemia nauplii. Background technique [0002] Since Seale in the United States used the nauplii hatched from Artemia eggs as live bait for flounder larvae in 1933, Artemia nauplii has gradually been highly valued by aquaculture workers at home and abroad. Essential bait for aquatic seedlings. [0003] After Artemia eggs hatch under suitable conditions, Artemia nauplii and unhatched Artemia eggs and egg shells are difficult to separate. These egg shells and unhatched eggs are in the nursery pond. On the one hand, the egg shells will rot and spoil the water quality. Or water pollution or disease occurs due to bacteria, fungi, etc. carried on the egg shells; on the other hand, some aquatic seedlings eat egg shells or unhatched Artemia eggs by mistake and block the digestive tract to cause death. There are many way...
