Problems solved by technology

This type of agitator is mainly composed of the hub and the stirring paddles on the hub. During use, the airflow in the mixing tank accumulates on the stirring shaft connected to the hub, and the airflow is directly passed by the hub without being dispersed. The space between the stirring paddle and t

Embodiment Construction

[0015] Such as figure 1 , figure 2 The illustrated aerofoil disc turbine agitator for a fermenter includes an agitator body 1, and the agitator body 1 includes a hub 11 and agitating blades 12 uniformly distributed along the circumference of the hub 11, between the agitating blade 12 and the hub 11 There is an annular airflow guiding plate body 13 therebetween, and the airflow guiding plate 13 is fixedly connected with the hub 11 and the stirring blade 12; the stirring blade 12 is installed on the airflow guiding plate body 13 in an oblique shape. By setting the air flow guide plate 13 between the hub 11 and the stirring blade 12, during use, the rising air flow will be blocked by the air flow guide plate 13, and then translate to the stirring blade 12 along its air flow guide plate 13, and the stirring blade 12 Stir it to disperse the airflow; this setting can control the rising airflow, effectively prevent the airflow from directly passing through the agitator body 1 witho...

Abstract

The invention relates to a mixer and particularly relates to an airfoil blade disk turbine mixer used in a fermentation tank. The technical scheme provided by the invention is as follows: the airfoil blade disk turbine mixer used in the fermentation tank comprises a mixer body, wherein the mixer body comprises a wheel hub and mixing blades which are uniformly distributed along the circumferential direction of the wheel hub, annular airflow guiding plate bodies are arranged between the mixing blades and the wheel hub, the airflow guiding plates are fixedly connected with the wheel hub and the mixing blades, the mixing blades take the shape of an airfoil and are obliquely arranged on the airflow guiding plate bodies, wherein one ends of the mixing blades, which are connected with the airflow guiding plate bodies, are roots, the other ends of the mixing blades are terminals, the cross sections of the ends are arc-shaped, and corners of the ends are provided with circular arc chamfers. By adopting the technical scheme, the invention provides the airfoil blade disk turbine mixer used in the fermentation tank which has airflow control capability and improves the airflow dispersion effect.

Description

technical field [0001] The invention relates to a stirrer, in particular to an airfoil disc turbine stirrer for a fermenter. Background technique [0002] In fermentation equipment, due to the high oxygen consumption requirements of most fermented products, standard fermentation tanks with both ventilation and mechanical stirring are the most widely used, and are widely used in various fields such as antibiotics, amino acids, and citric acid. The technical key to fermenter design lies in the stirring system. The performance of the stirring system is directly related to the growth, morphology, absorption and metabolism of oxygen and nutrient, which directly affects the fermentation unit and yield. [0003] At present, the design of the stirring system of the fermenter appearing on the market and data is that the bottom layer adopts a disc turbine type agitator, which is mainly used for the dispersion and mixing of gas, while the upper layer generally adopts a wide blade axia...
