AI Technical Summary

Technical Problem

Traditional cultivation devices use mechanical stirring, which causes shear force damage to microorganisms. The shaft seal structure is prone to leakage, increasing the risk of contamination by other microorganisms and compromising the stability of the cultivation system.

Method used

It adopts a non-contact magnetic coupling transmission structure between the magnet and the rotating ring, and achieves shaftless stirring by using the opposite pole attraction characteristics of neodymium iron boron strong magnets and magnets. Combined with flexible stirring plates and scrapers, it forms a low-frequency, wave-like flow. With the design of the diverter and mixing tank, it ensures uniform dispersion of nutrients.

Benefits of technology

It avoids the strong shearing damage to microorganisms caused by mechanical stirring, reduces the contamination rate of miscellaneous bacteria, ensures the aseptic stability of the culture system and the uniform distribution of nutrients, and shortens the microbial propagation cycle.

Abstract

The application provides a mine soil microbial cultivation device, which comprises a supporting plate, a cultivation tank, a mounting frame, a magnetic element, a rotating ring, a liquid supplementing assembly and a conveying assembly. The cultivation tank is connected with a top tank cover to form a cultivation cavity, and the mounting frame and the magnetic element are arranged in the cultivation cavity. The magnetic element is rotatably connected with the mounting frame and the cultivation tank base at two ends, and stirring plates and scrapers are arranged on the two sides. The scraper is in contact with the tank bottom. The rotating ring is sleeved outside the cultivation tank and is slidably connected, and a plurality of neodymium-iron-boron strong magnets are arranged in the rotating ring. The polarity of the magnets is opposite to that of the magnetic element. A driving part for driving the rotating ring to rotate is arranged on one side of the cultivation tank. The liquid supplementing assembly is arranged on the top of the cultivation tank and is used for adding culture medium and nutrients. The conveying assembly is arranged on the supporting plate and is used for conveying the cultivated microorganisms to the soil. The device realizes shaftless stirring through the magnetic force coupling of the magnetic element and the rotating ring, and solves the problems of microbial damage caused by mechanical stirring, easy leakage and pollution of shaft seals in traditional devices, and improves the cultivation stability and efficiency.
