Description
Technical field
The utility model relates to a kind of mixing plant, especially relates to a kind of efficient heterogeneous mixing plant.
Background technology
Mixing plant is a kind of to liquid, solid, gas medium forced convertion the device of Homogeneous phase mixing or reaction, and it is various in style, is widely used in the industries such as oil, chemical industry, food, medicine, agricultural chemicals, scientific research.Along with producing improving constantly of the diversity of product, complexity and product requirement, also higher to the requirement of mixing plant, its emphasis is also different.
Existing agitating device is generally that motor is passed on by belt transmission or gear train, the torque of common motor is lower on the one hand, cannot drive agitating device relatively high to viscosity, need strong mixing, the heterogeneous material of Strong shear power process stirs, or do not reach desirable dispersion effect; On the other hand, most of agitating device cannot regulate the torque of stirring and the size of rotating speed, causes the loss of equipment idle running and the waste of energy consumption.
The temperature of stressed excessive, the hybrid reaction material of paddle and the problem such as even concentration is not good, stirring efficiency is low, mixing time is long are existed for single dasher, even can affect the homogeneity of product quality.For the material that viscosity is slightly large, the running of usual agitating device can not form effective systemic circulation in whole still, that is they only can disperse or shear from they not far Part portions materials, and can not be disperseed and shear from the material away from them due to height retardance.As patent CN20052000604.4 discloses a kind of high-viscosity material solid-liquid heterogeneous reaction high efficiency reactor, the stator fixed mount of autoclave body bottom equipment high shear stirred reactor is fixed on kettle, and the rotating disk of high shear stirred reactor is connected with motor.But because the high shear stirred reactor bottom it is due to high-speed rotation, make surrounding liquid obtain larger static energy, this portion of energy had both affected the stability of mixing plant, did not reasonably utilize it again, produced the waste of energy consumption.
In addition, mixing plant general structure more complicated, cleaning is inconvenient; In whipping process, easily produce dead angle, especially for high viscosity liquid, also easily cause after fluid discharge and stir material deposition, clean thorough not, the stirring of subsequent material is had an impact.
Chinese patent CN204247110U discloses a kind of heterogeneous system agitating device, comprises reactor main body, chuck, thermometer sleeve, paddle, reductor and motor; Reactor body top is provided with charge door and visor, is provided with discharging opening bottom it; Chuck is sleeved on reactor body exterior, and its top is provided with coolant outlet, and bottom is provided with cooling water inlet and evacuation port; Thermometer sleeve is arranged on described reactor main body side, and its entirety stretches into reactor body interior, and upper end open is in described reactor body top; Reductor and motor are arranged on reactor body top; Paddle is pusher paddle, and described reactor body interior is stretched in its underpart, and its upper end connects described motor by reductor.This patent improves its torque by reductor, the abundant mixing in radial direction can be realized, but while its torque increases, its rotating speed is reduced, affect the decentralization of heterogeneous material, especially for high viscosity system, then need to reach mixed effect by the longer time, thus reduce mixing quality and efficiency; And be difficult to the abundant mixing realized axially, easily cause the deposition of high viscosity high specific gravity material, blocking outlet.
