Background technology
In changing food waste, the proportion of each component differs greatly, percentage of impurity is high, poor fluidity.For this mixing changing food waste that is pulp-like, heavy phase thing free settling and there is viscosity higher, require to adopt rational rabbling mechanism with suitable stir speed (S.S.), changing food waste material fully to be stirred, form uniform suspension, avoid heavy phase material deposition wherein, so that cause that the discharging opening of kettle stops up.
Be current a kind of distilling kettle for the treatment of changing food waste as depicted in figs. 1 and 2.In the kettle 10 of this distilling kettle, only in its straight tube chamber, be provided with the paddle agitator that a multistage paddle agitator 5(adopts multilayer) to stir material, thereby reach, force material suspended technological requirement.Wherein, external motor drives shaft 4 around its rotation OO ' rotation by power transmission shaft 1, shaft coupling 3, drives 5 pairs of materials of agitator to stir, and the material after uniform stirring can be from discharging opening 11 dischargings.Wherein power transmission shaft 1 is arranged on distilling kettle by block bearing 2 supportings, and shaft 4 stretches out downwards and suspends.
Yet, in this distilling kettle, multistage paddle agitator 5 simple in structure, be applicable to more rotating speed extremely low, in the hybrid technique of the less demanding low viscosity material of mixing effect, in changing food waste processing procedure, have the following disadvantages:
1), in order fully to stir to form uniform suspension, need to increase the stirring intensity of agitator, thereby mixing arm adopts the long and wide blade that twists into arcuation mostly.This blade processing and manufacturing difficulty is high, and easily occurs and accumulated deformation, and even bending damages, and causes service life low;
2), via the stirring of multistage paddle agitator 5, material easily forms fixedly flow pattern---form around the peripheral flow of multistage paddle agitator 5, as shown in the arrow in Fig. 2, along the peripheral flow of direction of rotation w.So not only be difficult to reach and make material suspended technological requirement, even easily cause heavy phase material to form centrifugal sedimentation;
3), the heavy phase material of centrifugal sedimentation is easily accumulated in the conical bottom chamber (being kettle reducer) in kettle 10, the still wall in this region of wearing and tearing, easily causes the discharging opening 11 at the bottom of still to stop up;
4), shaft 4 end that stretches into kettle 10 bottoms do not supported, this shaft 4 is cantilever beam structures, causes the rigidity of shaft 4 low, deflection increases, axial movement value increases, thereby reduces service life of equipment, has a strong impact on mixing effect.
