Description
Technical field：
The utility model belongs to chemical machinery or equipment manufacturing technology field, and in particular to a kind of urea and propane diols synthesis
The feed arrangement of propylene carbonate alcohol.
Background technology：
Propylene carbonate alcohol is a kind of important chemical products, is widely used in Polymeric Industry, gas separating technology and electricity
Chemical industry.The alcoholysis of urea of urea and propane diols synthesizing acrylic alcohol, not only raw material urea is cheap and easy to get, and directly profit
With the propane diols produced in dimethyl carbonate joint production of propylene glycol device production process, the follow-up sales of propane diols are solved the problems, such as, most
For it is important that byproduct of reaction ammonia can be recycled to urea production unit, synthetic method realizes zero-emission, as current tool
Competitive propylene carbonate alcohol production method.In industrial processes, it is necessary first to which urea feeding is added in reactor,
Then reacted again in the presence of catalyst with propane diols.Conventional urea feeding process is：Urea is transported to device area by storehouse and hung
Mouth is filled, material loading platform is then lifted into hoist crane, urea packaging is opened and urea is put into automatic quantitive scale, by urinating after metering
The screw(-type) feeder of plain bin bottom gradually delivers to urea dissolution kettle, is blended under conditions of 80 DEG C with propane diols and catalyst
Row primary reaction.Pilot process finds that conventional urea feeding process has problems with：(1) urea raw material dosage is big, and work is strong
Degree is big, it is necessary to increase external coordination Labor Workers on the basis of original operating personnel；(2) urea is lifted into the laggard weigher of material loading platform,
But weigher import is smaller, and amount of urea is larger, feed time can not meet former design production capacity；(3) air humidity is easily made
Into urea moisture absorption caking, cause feed bin blowing difficult, and after urea moisture absorption, sack cleaner failure in urea feed bin top rises not
To dust removing effects；(4) feeding device only has an electric hoist, and use intensity is very high, if there is failure, easily causes
System shutdown.
The content of the invention：
The purpose of this utility model is to overcome the shortcoming of prior art there is provided a kind of alcoholysis of urea synthesizing acrylic
The feeding device of alcohol, solves existing feeding device labor intensity greatly, appliance arrangement use intensity is high, weighing takes considerable time,
The easy moisture absorption caking of urea.
To achieve these goals, the feeding device for the alcoholysis of urea synthesizing acrylic alcohol that the utility model is related to,
Including mixing and stirring tank, level gauge, heater, urea feeding device and propane diols feeding device, level gauge is arranged on
It is used for the content for measuring mixing and stirring tank propane diols in mixing and stirring tank, mixes and heater is set on the outside of tank, urine
Plain feeding device and propane diols feeding device is connected with mixing and stirring tank.
The urea feeding device that the utility model is related to includes setting on the downside of chute, belt conveyor and elevator, chute
On belt conveyor one end top, elevator bottom charging aperture is connected with the belt conveyor other end.Propane diols feeding device bag
Propane diols storage tank and delivery pump are included, is connected propane diols storage tank with mixing and stirring tank by delivery pump.
The utility model compared with prior art, with advantages below：(1) device for mechanical degree is high, and reduction work is strong
Degree, reduces labour；(2) urea is avoided to open the moisture absorption caking for weighing and causing；(3) operating process does not need special skill simply
Art personnel；(4) many urea feeding devices interval or work simultaneously, reduce the fault rate of feeding device.
Brief description of the drawings：
The feeding device structure principle chart for the alcoholysis of urea synthesizing acrylic alcohol that Fig. 1 is related to for utility model.
Embodiment：
Below in conjunction with the accompanying drawings and the utility model is described in further detail by specific embodiment.
Embodiment 1：
The feeding device for the alcoholysis of urea synthesizing acrylic alcohol that the present embodiment is related to, including mixing and stirring tank 1, liquid level
Device 2, heater 3, urea feeding device and propane diols feeding device, level gauge 2, which is arranged in mixing and stirring tank, to be used for
Measure and heater 3, urea feeding device and third are set on the outside of the content of the propane diols of mixing and stirring tank 1, the tank body of mixing and stirring tank 1
Glycol feeding device is connected with mixing and stirring tank 1.
The urea feeding device that the present embodiment is related to includes chute 4, belt conveyor 5 and elevator 6, and the downside of chute 4 is set
Put on one end top of belt conveyor 5, the bottom charging aperture of elevator 6 is connected with the other end of belt conveyor 5.Propane diols feeding is filled
Put including propane diols storage tank 8 and delivery pump 7, connected propane diols storage tank 8 with mixing and stirring tank 1 by delivery pump 7.
Many are mixed in the feeding device practical work process for the alcoholysis of urea synthesizing acrylic alcohol that the present embodiment is related to
The parallel operation of agitator tank 1 is closed, while setting many urea feeding devices.
The feeding device specific work process for the alcoholysis of urea synthesizing acrylic alcohol that the present embodiment is related to is：By the third two
Alcohol is pumped into mixing and stirring tank 1 by delivery pump 7 from propane diols storage tank 8, treats that liquid level reaches process set value, stops adding, with
Packed load weighted urea is poured into chute 4 by this simultaneously, and urea is slided along chute 4 falls into the one end of belt conveyor 5, by belt
Conveyer 5 is transported to the bottom of elevator 6, and urea is transported up adding in mixing and stirring tank 1 from the top of elevator 6 by elevator 6,
During propane diols and urea charging, it is stirred continuously and heats, temperature in mixing and stirring tank 1 is heated to 70-80 DEG C, urine
Element dissolving with propane diols constitutive material mixed liquor, then raw material mixed liquor is delivered into the urea dissolution kettle of existing equipment with
Catalyst mixing carries out primary reaction.
