Description
Technical field
The present invention relates to a kind of horizontal type etherifying reactor, specifically adopt semidrying, the cellulosic horizontal type etherifying reactor of dry production, belong to the chemical machinery technical field.
Background technology
In prior art, at present, the etherifying reactor overwhelming majority that is used for industry such as production of cellulose is to adopt vertical retort, and is the 5m that early development goes out mostly
3Vertical etherifying reactor only has a spot of 20～30m
3Etherifying reactor.Wherein, 5m
3Vertical etherifying reactor just progressively eliminate 30m
3The technical feature of still owing to do not break through, fail for a long time to be applied.And vertical etherificate still is installed stir shaft mainly by cylindrical shell, reaction kettle body, chuck anabolic reaction still container body in reactor container body, and agitator is installed on the stir shaft, and is fixedlyed connected with base by speed reduction unit, motor.Because the restriction of this kind structure, mixing effect is inhomogeneous, adds that exchange capability of heat is not enough, makes that single still annual production can not get improving.Like this, not only increased the investment of equipment use place, process pipeline, instrument control etc., and brought bigger difficulty to equipment control.Simultaneously, when originally vertical etherificate still fluid foods adds the kettle container, the material layering phenomenon can be occurred in the still, the complete homogeneous phase blending of material in the kettle can not be guaranteed to realize.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, a kind of mixing effect is even, heat exchange property is high thereby provide, and output per single reactor and quality product are effectively improved, and can shorten the horizontal type etherifying reactor of process treatment time simultaneously.
According to technical scheme provided by the invention, a kind of horizontal type etherifying reactor, it mainly adopts and is provided with chuck forms kettle jointly in cylindrical shell, the cylindrical shell end socket is installed at the cylindrical shell two ends, the cylindrical shell end socket is used to seal kettle, cylindrical shell and underframe are connected and fixed, the center is provided with a rotation stir shaft in kettle, the stir shaft two ends are set with left end shaft joint sealing and right-hand member axle joint sealing, the left end shaft joint sealing is connected with the right bearing seat with left shaft holder respectively with right-hand member axle joint sealing, left shaft holder and right bearing seat and underframe are fixed, the right bearing seat is connected with speed reduction unit by shaft coupling, and speed reduction unit connects motor and is fixed on the motor cabinet, and feature is to stagger on the described stir shaft a plurality of colter formula agitators are installed, colter formula agitator is not equally spaced along the stir shaft axis, and distribution angle is 90 ° or 120 °.
Described colter formula agitator is made up of paddle arms and plough formula blade, and plough formula blade is arranged on the paddle arms.
Described left end shaft joint sealing is connected to form by last stuffing box and following stuffing box, is respectively arranged with insertion ring in last stuffing box and following stuffing box, and the described stuffing box of going up is provided with cooling water jecket outward respectively with following stuffing box casing.

Compared with the prior art the present invention has the following advantages:
1, the present invention compares with the vertical response still of present use, has overcome when the fluid foods of different densities adds the kettle container demixing phenomenon that can occur fully; Can make material obtain mixing and increasing uniformly the specific surface area of reaction within a short period of time, avoid the local phenomenon that dead band or low-speed motion district occur simultaneously, quicken material and accurately mix at a high speed, effectively shorten the process time.
2,,, do not have the danger that produces eddy current owing to adopted the agitator of colter type in the discharge stage yet.Under the material and long stapled situation that material can occur reuniting, can also adopt the auxiliary element support, fly cutter assembly destroyer is set, can carry out fragmentation and shearing the material and the macrofiber of reuniting at the inner core sidewall, it is more even that material is distributed, and realizes the complete homogeneous phase blending of material in the kettle.
3, gland seal device is designed to double-deck packing seal combination, make it to have wear-resisting, acid and alkali-resistance, have the good self-lubricating property and the characteristics of thermal conductivity, can stop simultaneously leaking outside of interior material of still and gas again, simultaneously certain effect played in the support of stir shaft.
4, the replacement cycle of this kind structured packing reaches 6～8 months, is much higher than currently available products, has also guaranteed the long-time running of kettle in the smooth long term running of having guaranteed stuffing box.
5, can meet the requirement of efficient energy-saving.
