Abstract
The utility model discloses a desolvation kettle. The desolvation kettle comprises a kettle body, wherein seal heads are installed at the two ends of the kettle body; a stirring shaft is arranged in the central position in the kettle body and is connected with a speed reducer via a coupling; the speed reducer is connected with a motor and is fixed on a motor base; paddle stirrers are installed on the stirring shaft; a gate stirrer is installed at the lower end of the stirring shaft; a scraper is arranged at the bottom end of the gate stirrer; at least two blades are arranged on the paddle stirrers and are axially distributed in equal space along the stirring shaft. The desolvation kettle has the beneficial effects that the paddle stirrers are arranged on the stirring shaft, at least two blades are arranged on the paddle stirrers, and the gate stirrer is arranged at the lower end of the stirring shaft, thus being favorable for improving the stirring efficiency of the bottom of the kettle body; besides, the scraper is also arranged at the bottom of the gate stirrer, so that the materials can be prevented from being stuck to the bottom of the kettle body, and the desolvation efficiency is further improved.
Description
Technical field
The utility model relates to a kind of exsolution apparatus, relates in particular to a kind of hydroxypropyl cellulose precipitation still.
Background technology
At present, in the production process of domestic hydroxypropyl cellulose, reaction dissolvent is all that these solvents need recycling use with two kinds of solvents of toluene-isopropyl alcohol composite forming according to a certain percentage.Because reacted hydroxypropyl cellulose has certain viscosity, existing precipitation still, because mixing effect is bad, is easy to form dead angle at the bottom of still, and at the bottom of material being adhered to be deposited in still, cause removal of solvents weak effect, increase the difficulty of the post processing of hydroxypropyl cellulose.
Utility model content
The problem that the utility model is bad for prior art precipitation still mixing effect, precipitation rate is low, object is to provide a kind of efficient hydroxypropyl cellulose precipitation still.
For achieving the above object, the technical solution adopted in the utility model is as follows: a kind of precipitation still, comprise kettle, described kettle two ends are provided with end socket, and in kettle, center is provided with a shaft, and described shaft is connected with decelerator by shaft coupling, decelerator connects motor and is fixed on motor cabinet, on described shaft, dasher is installed, described shaft lower end is provided with gate stirrer, and described gate stirrer bottom is provided with scraper.
On described dasher, be provided with at least 2 blades, described blade is axially equally spaced along shaft.
Compared with prior art, the beneficial effects of the utility model are mainly reflected in: on shaft, be provided with dasher, on dasher, be provided with at least 2 blades, shaft lower end is provided with gate stirrer, is conducive to improve the stirring efficiency of autoclave body bottom; In addition, in gate stirrer bottom, be also provided with scraper, can prevent that material from sticking at autoclave body bottom, further improves precipitation efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: kettle 1, end socket 2, shaft 3, decelerator 4, motor 5, dasher 6, gate stirrer 7, scraper 8, blade 9.
The specific embodiment
Below in conjunction with specific embodiment, structure of the present utility model is described further.
As shown in Figure 1, a kind of precipitation still, comprise kettle 1, kettle 1 two ends are provided with end socket 2, in the interior center of kettle 1, are provided with a shaft 3, and shaft 3 is connected with decelerator 4 by shaft coupling, decelerator 4 connects motor 5 and is fixed on motor cabinet, dasher 6 is installed on shaft 3, and shaft 3 lower ends are provided with gate stirrer 7, and described gate stirrer 7 bottoms are provided with scraper 8; On dasher 6, be provided with at least 2 blades 9, described blade 9 is axially equally spaced along shaft 3.
On shaft 3, be provided with dasher 6, be provided with at least 2 blades 9 on dasher 6, shaft 3 lower ends are provided with gate stirrer 7, are conducive to improve the stirring efficiency of kettle 1 bottom; In addition, in gate stirrer 7 bottoms, be also provided with scraper 8, can prevent that material from sticking at autoclave body bottom, further improves precipitation efficiency.
