Abstract
Scrape wall agitating device the invention discloses a kind of helical-ribbon type, including agitating shaft, helical-ribbon type stirring slurry and it is active scrape siding, wherein agitating shaft lower end is mounted in the central channel of helical-ribbon type stirring slurry end；In helical-ribbon type stirring slurry circumferentially staggered 90 ° between adjacent ribbon；It is active to scrape in the middle part of the ribbon connecting shaft that siding is sequentially arranged in helical-ribbon type stirring slurry.Compared with prior art, the invention has the following advantages that 1, reduce the retention areas of High-Sr granite in reaction kettle, heat exchange efficiency improves 5~6 times；2, wall technique is scraped using helical-ribbon type and increase turbulent flow of the fluid in whipping process in reaction kettle, improve stirring efficiency.
Description
Technical field
The present invention relates to the stirring apparatus for reaction kettle of chemical industry, food or pharmaceutical industry more particularly to helical-ribbon type to scrape wall stirring
Device.
Background technique
Reaction kettle is widely used in chemical industry, food or pharmaceutical industry as a kind of material reaction pressure vessel, to complete sulphur
The technical process such as change, hydrocarbonylation, polymerization, condensation.At present using more extensive reactor agitator mainly have paddle, push type and
Turbine type, wherein paddle agitator using blade weld or bolt on wheel shaft, be used primarily in liquid-liquid system for mix,
Temperature is uniform, is chiefly used in preventing solid from settling in solid-liquid system.Propeller agitator is mainly used in low viscosity fluid, stirring
When, by sucking above blade, lower section is discharged fluid with cylindric spiral shape, and in stirring, the turbulent extent of fluid is not high, is applicable in
In the big occasion of low-viscosity, flow.Turbine agitator, which is divided into two class of open type and disc type, can handle viscosity using than wide
The very wide fluid of range.
It is main in such a way that chip stirring slurry is arranged on vertical agitating shaft in the prior art, by the top of reaction kettle
Motor driven agitating shaft rotation, so that stirring slurry be driven to rotate.When reaction kettle volume is smaller, this structure, which can be used, to be wanted
It asks；When reaction kettle volume is larger, since material can only can only be in same plane by the centrifugal force of horizontal direction, material
Interior movement cannot move up and down, and cause the material between each layer that cannot be sufficiently mixed, and it is uneven in turn result in stirring.In order to mention
High mixing quality can only extend mixing time, reduce production efficiency.
Summary of the invention
Goal of the invention: the object of the present invention is to provide a kind of helical-ribbon types to scrape wall agitating device, to realize to high viscosity material
Quick uniform, be sufficiently stirred.
Technical solution: helical-ribbon type scrape wall agitating device include agitating shaft, helical-ribbon type stirring slurry and it is active scrape siding, wherein
Agitating shaft lower end is mounted in the central channel of helical-ribbon type stirring slurry end；It is circumferentially staggered between adjacent ribbon in helical-ribbon type stirring slurry
90°；It is active to scrape in the middle part of the ribbon connecting shaft that siding is sequentially arranged in helical-ribbon type stirring slurry.
Helical-ribbon type stirring slurry includes the staggered ribbon of several circumference and the ribbon connecting shaft for connecting ribbon.
Helical-ribbon type stirring slurry is connect with end cap with agitating shaft bottom end.
It is sealed between agitating shaft and helical-ribbon type stirring slurry using O-ring seal.
It is sealed between helical-ribbon type stirring slurry and end cap using O-ring seal.
Working principle: using stirring slurry in high viscosity fluid to the shear ability of high viscosity fluid, in screw mixing slurry
Circumferentially staggered 90 ° between adjacent ribbon, shear force is improved, to increase the turbulent region of material stirring, improves and stirs
Efficiency is mixed, reduces stirring dead angle, the material in reaction kettle is sufficiently balancedly reacted, product has been effectively ensured
Quality.
The utility model has the advantages that compared with prior art, the invention has the following advantages that 1, reduce High-Sr granite in reaction kettle
Retention areas, heat exchange efficiency improves 5~6 times；2, wall technique is scraped using helical-ribbon type increase fluid in reaction kettle stirring
Turbulent flow in the process reduces stirring dead angle, improves stirring efficiency, the material in reaction kettle is sufficiently balancedly sent out
Raw reaction, improves product quality.
Detailed description of the invention
Fig. 1 is that helical-ribbon type scrapes wall agitating device installation diagram；
Fig. 2 is partial sectional view.
Specific embodiment
As shown in Figure 1, helical-ribbon type scrape wall agitating device include agitating shaft 1, stirring slurry 2 and it is active scrape siding 3, wherein stirring
1 lower end of axis is mixed to be mounted in 2 end center slot of stirring slurry；Stirring slurry 2 includes the ribbon 21 of several circumferential arrangements, connection ribbon
21 ribbon connecting shaft 22；Several active sidings 3 of scraping are sequentially arranged at the outer middle side part of ribbon connecting shaft 22.
Agitating shaft 1 is around own axes in rotation counterclockwise, driving stirring slurry 2 is in revolve clockwise or counterclockwise clockwise
Turn, while rotating, active in ribbon connecting shaft 22 scrapes siding 3 and be close to kettle wall, and the material on kettle wall is wiped off and kettle
Interior high temperature or low-temperature material mixes again.Wherein when heated condition, agitating shaft 1 drive stirring slurry 2 rotate clockwise, fluid to
On seethe.When quickly mixing is with cleaning state, agitating shaft 1 drives stirring slurry 2 and active siding 3 of scraping to rotate counterclockwise, fluid
It seethes downwards.
As shown in Fig. 2, end cap 4 be it is T-shaped, convex portion be embedded in 1 bottom centre hole of agitating shaft in, stirring slurry 2 and stirring
1 bottom end of axis is connect with end cap 4.
1 bottom end of agitating shaft is tightly set in 2 central channel of stirring slurry, and agitating shaft 1 and 2 notch top of stirring slurry use O-shaped sealing
5 sealing of circle.It is sealed between 4 flat contact position of 2 bottom end of stirring slurry and end cap using O-ring seal 6.
