Fig. 2 is refer to, Fig. 2 is the structural representation of second embodiment of the present utility model, and the utility model second is implemented
The alcohol conjunction kettle 1 of example is roughly the same with the alcohol conjunction kettle structure of first embodiment, is this with the different part of first embodiment
Also include baffle plate 17 and temperature regulating device 16 in embodiment, baffle plate 17 is solid hard material, for example, steel plate, right the utility model
Not limited to this, also other can be used to have the metal material of hardness, and baffle plate 17 is arranged on inner wall of kettle surrounding.Temperature regulating device 16 is set
Put and close kettle outer wall in alcohol, the temperature regulating device 16 is arbitrarily can be by equipment of the temperature control at -20~200 DEG C, in the present embodiment, control
Warm device 16 mainly acts on the outside that alcohol closes kettle body 1, and temperature control medium will not penetrate into polyolefin catalyst alcohol and close kettle
In internal system pipeline and valve.
Based on solid steel plate, the type baffle plate 17 is mostly installed at four inside reaction kettle body baffle plate 17 in the present embodiment
It is week, optimal, closed in the alcohol and two interior panellings 17 are provided with the inside wall of kettle body 1, and alcohol is closed into the decile of kettle body 1.
Why inner wall of kettle set baffle plate 17, be because when fluid viscosity it is little, speed of agitator is higher, and blade is placed on kettle
Center line when, the direction rotated with blade is follow kettle wall and slided by liquid, and liquid pours into kettle under the action of the centrifugal force in kettle
Wall, liquid level is set to increase along kettle wall, the liquid level of core declines, and forms a whirlpool, commonly referred to as swirl phenomenon, to avoid swirling
Phenomenon event installs baffle plate 17 in inner wall of kettle.The benefit for setting baffle plate is more filling of contacting between the reaction mass for making entrance
Point, magnesium salts and alcohol agent contact more fully, alcohol close it is more efficient.
Due to the reactor body of this embodiment, agitating device 6, reaction-ure feeding pipe group, discharge nozzle group, nitrogen purging
Pipeline 8, pressure tester 4, temperature measuring equipment 5, the composition of safety monitoring assembly 3, structure and feature and above-mentioned first embodiment phase
Together, do not repeat in addition herein.
When the alcohol provided using second embodiment of the present utility model is closed kettle and prepares polyolefin catalyst, need to by magnesium chloride and
Alcohols first occurs chemical reaction i.e. alcohol and closes process.The course of work is as follows：
Step 1, alcohol first is closed into kettle at nitrogen purge line 8 and valve with low-pressure nitrogen to replace 5~10 times.
Step 2, the valve on mineral oil feedstock pipeline 9 is then opened, mineral oil is added into alcohol closes kettle body 1.
Step 3, agitating device 6 is opened, sets speed of agitator as 50rpm, then opens the valve on magnesium salts feeding line 2,
Magnesium salts is added to alcohol and closed in kettle body.
Step 4, the temperature for setting temperature regulating device 16 is 50 DEG C.
Step 5, the valve on alcohol agent feeding line 7 is opened, alcohol agent is added into alcohol closes kettle body 1.
Step 6, the valve on thickener feeding line 10 is opened, thickener is added into alcohol closes kettle body 1.
Step 7, the valve in nitrogen purge line 8 is opened, low-pressure nitrogen injection alcohol is closed in kettle body 1 alcohol is closed into kettle sheet
Air is replaced in body 1, is repeated after replacing 5~10 times, is closed magnesium salts feeding line 2, alcohol agent feeding line 7, mineral oil feedstock pipe
Valve on line 9 and thickener feeding line 10.
Step 8, after stirring a period of time, the valve on sampling line 12 is opened, from the sampling analysis of sampling line 12.
Step 9, after analysis is qualified, the magnesium alcoholic solution configured is delivered to catalyst by the valve opened on discharging pipeline 11
Prepare in kettle or magnesium alcoholic solution can also be continued to be closed in kettle body 1 in alcohol with nitrogen preservation.
Fig. 3 is refer to, Fig. 3 is the structural representation of 3rd embodiment of the present utility model, and the utility model the 3rd is implemented
The alcohol that the alcohol of example closes kettle and second embodiment closes roughly the same in kettle structure, and difference is in the present embodiment, in addition to one
Kettle reactor outer circulation pipeline 14, the kettle reactor outer circulation pipeline 14 are located at outside kettle and upper cover and the kettle bottom of kettle body 1 are closed with the alcohol
Portion connects.The kettle reactor outer circulation pipeline 14 is provided with valve, the filter 18 of circulating pump 13 and one.From the kettle reactor outer circulation pipeline 14
A conveying pipeline 15 is drawn, the conveying pipeline 15 is provided with valve.The one end of kettle reactor outer circulation pipeline 14 is connected with discharging pipeline 11,
The other end and magnesium salts feeding line 2, alcohol agent feeding line 7, mineral oil feedstock pipeline 9, the either line of thickener feeding line 10
Connection, is not limited herein.The one end of kettle reactor outer circulation pipeline 14 is connected with the discharging pipeline 11 in the present embodiment, the other end and magnesium salts
Feeding line 2 is connected, and the valve of kettle reactor outer circulation pipeline 14 is set close to magnesium salts feeding line 2, circulating pump 13 and discharging pipeline 11
Connection, filter 18 are arranged between circulating pump 13 and discharging pipeline 11.Why the outside of kettle body 1 is closed in alcohol to set outside kettle
Pipeloop 14 is that reaction mass can be taken away by the circulation of kettle reactor outer circulation pipeline 14 because alcohol can discharge substantial amounts of heat during closing
Partial heat, the heat in alcohol conjunction kettle body 1 is reduced, another effect kettle reactor outer circulation pipeline 14 coordinates with baffle plate 17, leads to
Cross kettle outer circulation and baffle plate is provided with inside kettle, reduce bubble caused by mixing in material, what magnesium salts and alcohol agent contacted
More fully, the space of kettle can be more efficiently closed using alcohol, improves the space-time yield that alcohol closes kettle, accelerates alcohol to close reaction.
Due to the reactor body of this embodiment, agitating device 6, reaction-ure feeding pipe group, discharge nozzle group, nitrogen purging
Pipeline 8, pressure tester 4, temperature measuring equipment 5, safety monitoring assembly 3, composition, structure and the spy of baffle plate 17 and temperature regulating device 16
Sign is identical with above-mentioned second embodiment, does not repeat in addition herein.
When the alcohol conjunction kettle provided using 3rd embodiment of the present utility model prepares polyolefin catalyst, the course of work is such as
Under：
Step 1, first replaced 5~10 times with alcohol is closed into kettle at low-pressure nitrogen valve from nitrogen purge line 8 and thereon.
