Problems solved by technology

The general propeller type agitator is composed of 2 to 3 propulsion type propeller blades. The working speed is relatively high, which mainly causes axial liquid flow and produces a large circulation volume. It is often used in the medium viscosity range μ4 cp, but the use of propeller stirrers in the fermenter consumes too much power

Embodiment Construction

[0011] The present invention will now be further described in conjunction with specific examples, and the following examples are intended to illustrate the present invention rather than further limit the present invention.

[0012] Such as Figure 1~2 The propeller-type agitator shown includes a hub 1 and a blade base 2 welded on the hub 1. The blade base 2 is connected to the stirring blade 4 through a bolt 3. There are at least three stirring blades 4, and the width of the stirring blade 4 is 80 mm to 1000 mm. , more gas can be stored under the stirring blade 4 to make the gas dispersion more balanced.

[0013] Further, in order to obtain greater circulation capacity, there are four stirring blades 4 .

[0014] Inspired by the above-mentioned ideal embodiment according to the present invention, through the above-mentioned description content, relevant workers can make various changes and modifications within the scope of not departing from the technical idea of ​​the presen...

Abstract

The invention relates to a stirring device, and especially relates to a propeller-type stirring device. The propeller-type stirring device comprises a wheel hub and a blade seat welded on the wheel hub. The blade seat is connected to stirring blades through bolts. There are at least 3 stirring blades. The widths of the stirring blades are 80-1000mm. According to the invention, the widths of the stirring blades are 80-1000mm, such that more gas can be kept under the stirring blades, and gas dispersion is more balanced. The propeller-type stirring device can be widely applied in stirring in a fermentation tank.

Description

technical field [0001] The invention relates to a stirring device, in particular to a propeller type stirrer. Background technique [0002] The propeller agitator has a high rotation speed during stirring, which can force the material to move along the axial direction, so that the material can be fully circulated and mixed. The general propeller type agitator is composed of 2 to 3 propulsion propeller blades. The working speed is relatively high, which mainly causes axial liquid flow and produces a large circulation volume. It is often used in the medium viscosity range μ<10 4 cp, but using a propeller stirrer in a fermenter consumes too much power. Contents of the invention [0003] The technical problem to be solved by the present invention is: based on the above problems, the present invention provides a propeller stirrer used in a fermenter. [0004] The technical solution adopted by the present invention to solve the technical problem is to provide a propeller ty...
