Magnetic stirring hatching barrel

Abstract

The invention discloses a magnetic stirring hatching barrel, which comprises a water tank with supporting legs, wherein the center of the bottom of the water tank is provided with a raised boss, and the bottom between the boss and the lateral surface of the water tank is provided with an annular groove; a thimble is arranged nearby the center of the boss; the boss is positioned on the surface of the outer side of the water tank and connected with a magnetic rotating component; the thimble is provided with a driven stirring mechanism capable of rotating together with the magnetic rotating component; a matching cap is arranged in the center of the driven stirring mechanism, and the lateral periphery of the matching cap is connected with ship-type stirring bodies distributed in a radial shape; an inverse funnel-type screen silk gauze is arranged nearby the opening of the water tank; and an overflow pipe passes through the water tank nearby the opening. The magnetic stirring hatching barrel has the advantages of novel structure, high production efficiency, high hatching density, suitability for large-scale production, uniform hatching density, high oxygen dissolution, uniform oxygen dissolution and saving of water sources.

Description

technical field [0001] The invention relates to a microorganism cultivation and incubation equipment, in particular to a magnetic stirring incubation tank. Background technique [0002] Existing fry hatching bucket is the funnel-shaped bucket that tinplate is made. It is divided into three parts: inverted trapezoidal round platform, cone and barrel stand. There is a round yarn on the upper part of the barrel to divide the upper part of the barrel into two parts, the inner and outer parts. The water continuously enters from the bottom of the funnel, and the fish eggs are put into the interior, and they are turned and hatched as the water continues to enter. The outflowing water is automatically discharged out of the bucket through gauze filter. The hatching bucket is supported by a triangular bucket frame processed by steel bars and angle iron. Although the hatching principle of this kind of hatching bucket meets the biological requirements of fish hatching, there are some...

AI Technical Summary

Problems solved by technology

Although the hatching principle of this kind of hatching bucket meets the biological requirements of fish hatching, there are some problems: 1. The effective filtration area of ​​the gauze is too small, and the gauze is easy to be blocked during the hatching process of the fry, resulting in unbalanced water inflow and outflow

If you do not wash frequently, it is easy to spread eggs and escape seedlings, thus increasing the labor intensity of washing management, and at the same time, it is easy to damage fish eggs and fry, reducing the hatching rate, so that the hatching rate is generally only 60-70%. If the hatching rate is not managed properly Reduced to varying degrees

2. The yarn and the barrel are fixed together. If the yarn is damaged, it is difficult to replace the yarn

3. The main parts of the barrel are connected together, so it is difficult to disassemble, transport and replace parts

However, the control of the hatching bucket on the flow rate and the density of eggs still needs to be improved
