Abstract
The utility model belongs to the field of chemical industry, and relates to a water-jacketed glass-lined reactor, which comprises a reactor body, a speed reducer and a mixing impeller, wherein the mixing impeller is connected with the speed reducer outside the reactor body through a mixing shaft, and the reactor body is formed by combining a tank cover and a cylinder vertically; a material inlet is arranged on the tank cover, and a feed pipe is connected onto the material inlet; a jacket is sleeved outside the cylinder, and a cooling water inlet and a cooling water outlet are arranged on the jacket; and a circular material receiving disc is fixedly arranged at the middle lower part of the mixing shaft through a fastener, and an outlet of the feed pipe is positioned above the circular material receiving disc. The circular material receiving disc is fixedly arranged on the mixing shaft, so that materials falling on the circular material receiving disc are uniformly added into a reaction material under the action of centrifugal force, and thus reaction heat is uniformly produced, the synthetic yield of products is increased by 4% to 5%, and simultaneously, the harsh requirements of freezing indexes in the reaction process are reduced; a manhole is arranged on the tank cover to be convenient for the maintenance of the inside of the reactor body; and in addition, the circular material receiving disc is adopted, so that the mixing shaft keeps balance when the centrifugal force acts.
Description
Technical field
The utility model relates to a kind of water-jacket typ a kind of jade glass reaction still, belongs to chemical industry synthetic reaction field.
Background technology
Synthesizing phosphorous acid dimethyl ester technical process is carried out in the reactor that has chilled brine and stirring, course of reaction is to add a certain amount of methyl alcohol in reactor, under-25 ℃ of temperature environment conditions, open and stir, drip phosphorus trichloride then, a large amount of heat is emitted in reaction, because of the former pipeline that is designed to directly adds phosphorus trichloride, because of reason such as mixing effect and feed zone be too concentrated, cause the hot-spot reaction to produce dimethylphosphite and partly decompose and other accessory substances, synthesis yield is usually about 23%.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of water-jacket typ a kind of jade glass reaction still that can disperse charging, reaction good cooling results effectively and uniformly and can improve the product synthesis yield is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of water-jacket typ a kind of jade glass reaction still, comprise kettle, reductor and agitator arm, agitator arm is connected by the outer reductor of shaft and kettle, kettle is combined up and down by cover and cylindrical shell, cover is provided with material inlet, connect feed pipe on the material inlet, the outside of cylindrical shell is with chuck, chuck is provided with cooling water inlet and coolant outlet, it is characterized in that: the middle and lower part of shaft is fixed with circular receiver by securing member, and the feed pipe outlet is positioned at circular receiver top.
Described cover is provided with manhole.Can make things convenient for the maintenance of staff by manhole to kettle inside.
Described circular receiver need adopt the good material plate of corrosion resisting property, and owing to titanium alloy has in light weight, corrosion-resistant, suitable reaction medium characteristics widely, therefore circular receiver is preferentially selected titanium alloy material for use.
Because circular receiver is fixed on the shaft, therefore circular receiver and agitator arm keep coaxial rotation under the drive of reductor, material can be transported on the circular receiver by feed pipe after entering reactor, and under action of centrifugal force, add in the reaction mass uniformly, reaction heat is reduced under the situation of equal inventory greatly, the reaction good cooling results, and because therefore the material distributed uniform can improve synthesis yield.
The beneficial effect that the utility model had is: a kind of water-jacket typ a kind of jade glass reaction still is provided, by on shaft, fixing circular receiver, make the material that drops on the circular receiver under action of centrifugal force, add in the reaction mass uniformly, thereby reaction heat is evenly produced, be difficult for causing reaction heat to concentrate, make the product synthesis yield improve 4%～5%, alleviate course of reaction making excessive demands simultaneously freezing index; Manhole is set on the cover, makes things convenient for the kettle internal overhaul; In addition, adopt circular receiver can when centrifugal action, keep the shaft balance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, reductor; 2, shaft; 3, cover; 4, material inlet; 5, feed pipe; 6, cylindrical shell; 7, chuck; 8, cooling water inlet; 9, securing member; 10, circular receiver; 11, agitator arm; 12, coolant outlet; 13, manhole
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
As shown in Figure 1, water-jacket typ a kind of jade glass reaction still comprises kettle, reductor 1 and agitator arm 11, agitator arm 11 is connected by the outer reductor 1 of shaft 2 and kettle, kettle is combined up and down by cover 3 and cylindrical shell 6, cover 3 is provided with material inlet 4, connect feed pipe 5 on the material inlet 4, the outside of cylindrical shell 6 is with chuck 7, chuck 7 is provided with cooling water inlet 8 and coolant outlet 12, the middle and lower part of shaft 2 is fixed with circular receiver 10 by securing member 9, and the feed pipe outlet is positioned at circular receiver 10 tops.
Described cover 3 is provided with manhole 13.Can make things convenient for the maintenance of staff by manhole 13 to kettle inside.
Described circular receiver 10 needs to adopt the good material plate of corrosion resisting property, and owing to titanium alloy has in light weight, corrosion-resistant, suitable reaction medium characteristics widely, therefore circular receiver 10 is preferentially selected titanium alloy material for use.
Because circular receiver 10 is fixed on the shaft 2, therefore circular receiver 10 keeps coaxial rotation with agitator arm 11 under the drive of reductor 1, material can be transported on the circular receiver 10 by feed pipe 5 after entering reactor, and under action of centrifugal force, add in the reaction mass uniformly, reaction heat is reduced under the situation of equal inventory greatly, the reaction good cooling results, and because the material distributed uniform can make synthesis yield bring up to about 29%.
