Abstract
The utility model discloses a stirrer for a fermentation tank, which comprises a stirring shaft. Stirring blades are arranged on the stirring shaft. The stirrer is characterized in that the stirring shaft comprises a main shaft (1) and an auxiliary shaft (2) parallel to the same, a connector (7) is arranged between the main shaft and the auxiliary shaft, one end of the connector is fixed to the main shaft (7), the other end of the connector is sleeved with the auxiliary shaft (2), a middle shaft (9) is nested in the main shaft (1), a gear (3) is fixed to the lower end of the middle shaft, a gear (4) is fixed to the upper portion of the auxiliary shaft, the gear (3) and the gear (4) mesh with each other, the stirring blades are arranged below the gear (4) and fixed to the auxiliary shaft (2), and the stirring blades comprise a disc (5) and a plurality of blades (6) evenly distributed on the periphery of the disc. The stirrer can be used for the fermentation tank, and gas-liquid separation efficiency can be improved effectively.
Description
Technical field
The utility model relates to the fermentor tank stirring rake.
Background technology
Fermentor tank refers to the industrial device that is used for carrying out microbial fermentation.Adopt the stirring rake dispersion in the mechanical stirring airy fermentor tank dependence fermentor tank and smash bubble, to improve dissolved oxygen speed.
Be used for gas one liquid dispersive stirring rake in the existing fermentor tank and be generally the straight leaf turbine impeller of disk, belong to the radial flow stirring rake, this stirring rake comprises stir shaft and agitating vane, agitating vane comprises perpendicular to the disk of stir shaft and perpendicular to uniform several pieces of disk faces the blade sheet directly, disc centre is fixed on the stir shaft, and the blade sheet is fixed in the periphery of disk.This stirring rake is too small owing to centrifugal force in the zone near stir shaft, is easy to generate the dead band, and blade also forms air pocket behind easily, causes gas dispersion efficient not high, and energy consumption is also high.In order to alleviate above-mentioned technical problem, in the prior art, also have the straight leaf agitating vane of disk and oblique blade sheet are used in combination improving dispersion efficiency, but unsatisfactory.
The utility model content
The purpose of this utility model is to overcome defective of the prior art, and a kind of fermentor tank stirring rake is provided.
The following technical proposals that adopted the utility model solves above-mentioned technical problem:
A kind of fermentor tank stirring rake, comprise stir shaft, stir shaft is provided with agitating vane, wherein, stir shaft comprises main shaft 1 and countershaft 2, main shaft 1 is parallel with countershaft 2, is provided with link span 7 between main shaft and countershaft, and link span one end is fixed on the main shaft, the other end and countershaft socket, cover tunnel shaft 9 in the described main shaft, the lower end of tunnel shaft is fixed with gear 3, is fixed with gear 4 on the countershaft, gear 3 and gear 4 are meshing with each other, be provided with agitating vane under the gear 4, agitating vane is fixed on the countershaft 2, and agitating vane comprises disk 5 and is distributed in several blades 6 of disk periphery.
The design of main shaft, tunnel shaft and countershaft can be so that agitating vane not only can revolve round the sun around main shaft, and can carry out rotation around countershaft, because mixing center constantly changes, therefore can eliminate stirring rake and be easy to generate dead band and blade air pocket problem behind in zone near stir shaft.
Further, the main shaft 1 top gear 10 that is connected.Thereby can cooperating with the gear of transmission mechanism, this gear make main shaft center on the tunnel shaft rotation.
Further, also be provided with preset pieces 8 on the countershaft 2, described preset pieces has two, lay respectively on the link span 7 with link span 7 under, and be connected with countershaft 2.The design of preset pieces can avoid the relative link span of countershaft to slide up and down, thereby guarantees the gear of countershaft and the toothing of main shaft.
Further, the center fixation of described disk 5 on countershaft 2, radially axial vertical with countershaft 2 of disk 5.
Further, described blade 6 is a curved surface bucket.
Further, the outer rim of described blade 6 is provided with the waviness sawtooth.This design can increase contacting and shearing of blade and liquid, further improves dispersion efficiency.
Further, be fixed with a plurality of described agitating vanes on the countershaft 2.
When stirring rake of the present utility model uses, the tunnel shaft of cover is fixed on the fermentor tank in the main shaft, main shaft rotates around tunnel shaft through transmission rig transmission back wall, the rotating band of main shaft is dynamically connected frame and countershaft and agitating vane around the main shaft revolution, and because tunnel shaft maintains static, so gear 3 maintains static, and gear 4 and gear 3 engagements, therefore, but the rotation of link span driven gear 4 rotations again.
Fermentor tank of the present utility model can be used for fermentor tank with stirring rake, effectively improves Gas-Liquid Dispersion efficient.
