Abstract
The utility model provides an eccentric type stirring reaction still which comprises a still body and a stirrer. The eccentric type stirring reaction still is characterized in that the stirrer is deviated from the center of the reaction still, and the stirrer is a multi-layer stirrer which comprises a stirring shaft 2, a lower layer stirring blade 3 and an upper layer stirring blade 4. Relative motion between liquid layers is strengthened, turbulent motion between the liquid layers is increased, and stirring effect is obviously improved. No dead angle exists in stirring, and good stirring effect can be achieved on the condition that a baffle is not added. The eccentric type stirring reaction still can be suitable for stirring various thick materials, especially high-viscosity materials.

Background technology
Autoclave stirred reactor (reactor) is the key equipment in the chemicals production process.Quality, kind and the production capacity of chemical products have been determined.In Chemical Manufacture, the tank reactor that generally uses has vertical, horizontal two kinds at present, according to the design of reaction condition to reactor structure function and configuration annex.All can finish pre-set reactions steps with higher automaticity from the charging-reaction-discharging of beginning, the temperature in the course of reaction, pressure, mechanics be controlled important parameters such as (stirring, air blast etc.) carry out strict regulation and control.But kettle structure generally is cylindrical tube, and the nowed forming of fluid media (medium) in still is not complete homogeneous, and the design and use of agitating device are extremely important.
The reactor of prior art, agitator are installed in the reactor center more.The steadily of centre of gravity of this structure, easy for installation, but liquid produces " cylindric tow-away zone " around agitator.In the stirring reaction process, occur easily stirring the dead band, affect the even mixing of material.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and a kind of centering type stirred autoclave is provided.
The technical solution of the utility model is as follows:
A kind of centering type stirred autoclave comprises kettle (1) and agitator, it is characterized in that agitator departs from the center of reactor.
Described agitator also comprises kettle cover, transmission device, gland seal device, supporting, all adopts prior art.
Preferably, the off-centered distance of agitator is 10～30% of reactor radius.
Described agitator is the multilayer agitator, and agitator is comprised of shaft 2, lower floor's stirring arm 3 and upper strata stirring arm 4.
Preferably, lower floor's stirring arm is disc turbine stirring arm 7, and its blade is circular arc type or parabolic type concave surface; Upper strata stirring arm 4 is ribbon, described ribbon by stirring be with 5 and support bar 6 form, stir and to be with 5 to be connected on the shaft 2 through support bar 6.
Stirring is with 5 take shaft 2 as axle center spiral escalation or decline.
Stirring is 20～30 degree with the plane at 5 places and the angle of horizontal plane.
Preferably, the width that stirs with 5 is 0.005 ~ 0.5 meter, preferred 0.01 ~ 0.3 meter.
Preferably, at least a portion that stirs with 5 spirals that form is the up big and down small taper of diameter.
Preferably, the blade of described disc turbine stirring arm 7 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 stirring arm that are installed on the shaft.Material is realized evenly mixing under the Double stirring of ribbon and disc turbine stirring arm.The stirring of ribbon is mentioned near the material of shaft with 5, and the stirring vane of disc turbine stirring arm 7 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) adopt centering type to stir in this reactor, mixing center departs from container center, and liquid stream is residing pressure difference at the each point place, so that relative motion strengthens between liquid layer, has increased the turbulent motion between liquid layer, and mixing effect obviously improves.
2) adopt multilayer to stir, especially adopt spiral stirring and turbine stirring to combine, go for the material stirring of various thickness, especially the stirring of high-viscosity material.
3) stir without the dead angle, in the situation that does not add baffle plate, just can reach good mixing effect.Mixing effect is better than adding the general stirred autoclave of baffle plate.
4) mixer design of the present utility model is reasonable, is easy to install.
