Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a microbial strain feeding system. Background Technology

[0002] In microbial inoculation operations, the uniformity of inoculum distribution and the maintenance of inoculum activity are core factors affecting the effectiveness. Traditional microbial inoculation methods often involve directly spraying the inoculum solution into the target area through nozzles. During spraying, the inoculum solution enters the water body as a high-speed jet. This involves two rigid impacts: first, the nozzle outlet velocity is typically high, causing the microorganisms in the high-speed jet to collide directly with the water. Due to the high fluidity and incompressibility of water, the impact kinetic energy is transferred to the microbial cell walls almost without loss, easily causing cell rupture; second, the nozzle sprays above the water surface, and the liquid stream entrains a large amount of air when it falls into the water. The bursting of these air bubbles generates strong local shear forces, further exacerbating microbial damage. Therefore, existing methods suffer from significant impacts on microorganisms caused by the high-speed jet from the nozzle. Utility Model Content

The dispersing feeding component includes a frame, a semi-submerged roller, a nozzle assembly located above the roller, and a first driving component for driving the roller to rotate. The roller is rotatably mounted on the frame. The inlet end of the nozzle assembly is connected to the outlet end of the stirring device through a conveying pipeline with a conveying pump. The nozzle assembly is mounted on the frame, and the spraying direction of the nozzle assembly is towards the outer circumferential surface of the roller.

Each stirring blade includes at least two blades evenly distributed circumferentially along the stirring shaft. The end of the blade away from the stirring shaft is provided with an arc-shaped bend, and the bending direction of the arc-shaped bend is consistent with the rotation direction of the stirring shaft.

[0006] Preferably, the nozzle assembly includes multiple atomizing nozzles arranged parallel to each other along the roller axis, with the spray direction of each atomizing nozzle facing the outer peripheral surface of the roller, and the spray range of two adjacent atomizing nozzles forming an overlapping area on the outer peripheral surface of the roller.
