Abstract
The utility model provides a conical bottom surface stirring reaction kettle which comprises a kettle body (1) and a stirrer. The conical bottom surface stirring reaction kettle is characterized in that the bottom surface of the kettle body is the oval bottom with the conical center. The reaction kettle uses the oval bottom with the conical center so as to be high in particle suspension efficiency and good in stirring effect. Tests show that when the particles are granule quartz sand, the same stirring efficiency can be also achieved, and the power consumption of the conical bottom surface stirring reaction kettle is only 60% of the power consumption of a flat bottom reaction kettle.

Preferably, described stirred autoclave also comprises baffle plate 5, and the existence of baffle plate 5 can increase stirring efficiency, so that peripheral flow is transformed into the axial flow that is conducive to solid-liquid suspension.Baffle plate is generally the 4-8 piece, and width is 1/12～1/16 of kettle diameter.
Described agitator is the multilayer agitator, and agitator is comprised of shaft 2, lower floor's paddle 3 and upper strata paddle 4.
Preferably, lower floor's paddle is flat type turbine impeller 8; Upper strata paddle 4 is ribbon, described ribbon by stirring be with 7 and support bar 6 form, stir and to be with 7 to be connected on the shaft 2 through support bar 6.
Stirring is with 7 take shaft 2 as axle center spiral escalation or decline.
Stirring is 10～20 degree with the plane at 7 places and the angle of horizontal plane.
Preferably, the width that stirs with 7 is 0.02 ~ 0.2 meter.
Preferably, at least a portion that stirs with 7 spirals that form is the up big and down small taper of diameter.
Preferably, the blade of described disc turbine paddle 8 is 2 ~ 8, and evenly installs around linkage section.
Preferably, the still wall arranges chuck outward, or heat-transfer surface is set in device, also can carry out heat exchange by outer circulation.Mode of heating has electrical heating, hot water heating, conduction oil circulating-heating, Far-infrared Heating, outer (interior) coil pipe heating etc.
Preferably, the reactor material is carbon manganese steel or stainless steel.
Add a certain amount of high viscosity or suspended material in the stirred tank, start drive apparatus drive shaft and rotate with the ribbon, the disc turbine paddle that are installed on the shaft.Material is realized evenly mixing under the Double stirring of ribbon and disc turbine paddle.The stirring of ribbon is mentioned near the material of shaft with 7, and the stirring vane of disc turbine paddle 8 presses down these materials again, and like this, material can rotate and seethe up and down stirring, is that mixing of materials is even, is fully stirred.
The utility model has the advantages that:
1) form of the oval end of employing tapered centre in this reactor, the particle suspending efficiency is high, mixing effect is good.After measured, when particle is the granule quartz sand, reach same stirring efficiency, its power consumption only is 60% of flat reactor.And when using coarse granule, its suspending efficiency is higher than flat reactor and taper bottom surface reactor far away.Because the suspension of solids not only needs certain flow velocity, also need certain velocity perturbation, in the reactor of taper bottom surface, the turnover of liquid flow direction is fiercer, and the velocity perturbation of generation is large, more is conducive to the suspension of particle.
2) adopt multilayer to stir, especially adopt spiral stirring and turbine stirring to combine, go for various material stirrings, especially the stirring of suspended material.
3) mixer design of the present utility model is reasonable, is easy to install.
