Description

The special-purpose agitator of a kind of vertical type solid fermentor tank
Technical field
The utility model relates to a kind of fermentation equipment, is specifically related to a kind of agitator that is exclusively used in vertical digester.
Background technology
Solid fermentation is meant under the situation that does not have or almost do not have free water to exist, the bioprocesses of culturing micro-organisms in the water insoluble solid matrix of certain humidity is arranged.In the solid fermentation process,,, can cause in the fermenting process heat conduction inhomogeneous like this so be difficult for stirring because fermented product is solid-state, be unfavorable for the measurement of temperature of charge in the fermenting process, also be unfavorable for the abundant fermentation of material, can cause fermentation not thorough like this, fermentation efficiency is low.
The agitator of traditional vertical type solid fermentor tank is that stirring rake is fixed on the main shaft, main shaft stretches in the tank body and stirs, this simple stirring rake can only left rotation and right rotation move in tank body, can only realize the horizontal stirring of material like this, can not realize vertically stirring up and down of material, cause temperature of charge seriously inhomogeneous, influence fermentation efficiency and quality product.
Summary of the invention
The purpose of this utility model is that agitator can not fully stir in the above-mentioned prior art in order to overcome, and causes fermenting the deficiency insufficient, that fermentation efficiency is low and provides the good vertical type solid fermentor tank of a kind of mixing effect special-purpose agitator.
The utility model is that the technical scheme that adopts that achieves the above object is: the outside is a tank body, and the tank inner chamber middle is provided with casing, and casing top and tank body top seal are affixed, and main shaft vertically stretches into outside the tank body top the casing, main shaft upper end connection transmission mechanism; Set gradually thrust bearing device, spirochete and bearing on the main shaft in casing from top to bottom; Thrust bearing device connects transmission mechanism and is connected with main shaft by joint flange, and bearing is arranged on the casing lower end; The main shaft lower end extends to outside the casing and is positioned at the tank body bottom, and the main shaft lower end is provided with disk leaf turbine impeller; Casing upper position place is provided with two opening for feeds, lower position and is provided with a discharge port.
The beneficial effects of the utility model: in tank body, realize to about the material, about stir simultaneously, help the more abundant of fermentation materials fermentation, thereby improved fermentation rate.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1. casing; 2. thrust bearing device; 3. main shaft; 4. joint flange; 5. transmission mechanism; 6. spirochete; 7. opening for feed; 8. discharge port; 9. disk leaf turbine impeller; 10. bearing; 11. tank body.
Embodiment
Referring to Fig. 1, outside of the present utility model is the tank body 11 of sealing, in tank body 11 inner chamber middles casing 1 is set, and fixedlys connected with the top of tank body 11 and seal in the top of casing 1.Main shaft 3 vertically stretches into outside the top of tank body 11 casing 1, and the upper end of main shaft 3 is positioned at outside the top of tank body 11, and the upper end of main shaft 3 connects transmission mechanism 5.On the main shaft 3 in casing 1, installed thrust bearing assembly 2, spirochete 6 and bearing 10 successively from top to bottom.Thrust bearing device 2 connects transmission mechanisms 5, and thrust bearing device 2 is connected with main shaft 3 by joint flange 4, and spirochete 6 is fixedly welded on the main shaft 3, and bearing 10 is arranged on the lower end of casing 1.The lower end of main shaft 3 extends to outside the casing 1, and is positioned at tank body 11 bottoms, in the lower end of main shaft 3 disk leaf turbine impeller 9 is installed.Casing 1 upper position place is provided with two opening for feeds 7, and lower position is provided with a discharge port 8.
Spirochete 6 of the present utility model is the solid type spiral, and the screw-blade of spirochete 6 is to be stamped to form by the steel sheet about 5mm, is welded to then on the main shaft 3, and the spiral of spirochete 6 distance is 0.5 times of diameter of spirochete 6.Main shaft 3 adopts the stainless-steel pipe of long each sections of 4cm to make, and can adjust the length of main shaft 2 according to the size of tank body 11, and under the identical situation of intensity, its quality is little, and is interconnection also convenient.
During the utility model work, transmission mechanism 5 rotates, and drives main shaft 3 rotations by thrust bearing device 2 and joint flange 4, and material obtains very big centrifugal intertia force under the drive of the higher rotation speed of spirochete 6, the material of bottom is risen to top, realized the stirring up and down of material like this; When stirring up and down, main shaft 3 drives 9 rotations of disk leaf turbine impeller, realizes stirring about material.
