Description
Technical field
The invention belongs to field of chemical equipment, more particularly to the reaction kettle that the dangerous solid applied to high activity feeds intake is solid
Body feeding device.
Background technique
In Chemical Manufacture, the case where solid material is added into the reaction kettle for fill liquid material is frequently encountered.If
Be open wide reaction system and be added solid material reactivity it is lower, can with direct drug injection spoon by solid by several times be added reaction kettle
In, and for thering is dust or volatile solvent to drift the region that feeds intake, it causes damages to the health of operator；If necessary
Be added high activity dangerous solid material, such as sodium hydrogen, lithium aluminium hydride reduction, organophosphorus ligand meet air it is unstable, easily decompose
The even material of explosion on fire, it is necessary to using the glove box of inert gas shielding, or the glass of application Schlenk device
Bottle is operated, and both methods is high to equipment requirement, operates extremely complex, and required investment is too big, and is only limitted to reality
Test room use, it is difficult to be applied to large-scale industrial production.
Summary of the invention
The purpose of the present invention is to provide one kind can be realized under inert gas protection, by the dangerous solids of high activity
Expect it is intermittent be added in reaction kettle, avoid material because caused by ingress of air decompose or safety problem, can also solve
Dust drifts the problem of with solvent volatilization, makes the controllable reaction kettle solid feeding device of process safety that feeds.
To achieve the above object, the technical scheme adopted by the invention is that：Including connecting pipe and tank body two parts,
It is characterized in：It is equipped with controlled valve at the middle part of connecting pipe, the both ends of pipeline are equipped with ready-packaged joint, the ready-packaged joint point at both ends
It is not connected with the ready-packaged joint of the ready-packaged joint of reaction kettle interface and tank base, and uses metal chuck by connecting pipe respectively
Two groups of ready-packaged joints at both ends are fixed, and the sealing of chuck blank cover is equipped at the top of tank body；The connecting pipe with react
Gasket seal is mounted between each ready-packaged joint between kettle interface and connecting pipe and tank base.
The tank body includes the liner and metal shell made by transparent material, has form with a scale in the middle part of tank body.
The bottom of the tank body is equipped with controlled valve, and the two sides above tank body are respectively equipped with the access port of inert gas and let out
Mouth is pressed, is equipped with controlled valve on inert gas access port and pressure relief opening.
Compared with prior art, the present invention having the following advantages that：
(1) there is controlled valve on connecting pipe of the invention and tank body, controlled by double valve, reaction kettle can not influenced
In the case where interior environment, convenient replacement tank body, realizes intermittent multiple batches of charging during solid charging；
(2) tank body part uses the liner and metal shell of transparent material production, both can avoid solid material to metal material
Corrosion, and the compressive resistance of tank body can be enhanced, it prolongs its service life；
(3) it is equipped with form with a scale, observable solid material position in the middle part of tank body, and passes through regulating switch valve and lazy
Property gas flow rate controls charging rate；
(4) connection of connecting pipe, tank body and reaction kettle, which connects, is connected by ready-packaged joint, is fixed with chuck, good airproof performance,
Installation is simple, convenient disassembly；
(5) the configuration of the present invention is simple, manufacturing cost is cheap, easy to operate, is suitable for promoting the use of.

Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1, Fig. 2 are the structural schematic diagrams of reaction kettle solid feeding device.As seen from the figure, it includes connecting pipe
1 and tank body 2；The connecting pipe 1 is made by metal material, and controlled valve is equipped in the middle part of connecting pipe 1
3, there is metal quick coupler 4 at the both ends of connecting pipe 1, are connected respectively with reaction kettle interface 5 and tank body 2；The tank
Body 2 includes the liner and metal shell made by transparent material；There is metal quick coupler 4 at 2 both ends of tank body, and bottom can
It is connected with connecting pipe 1, top can be sealed with chuck blank cover 6.For ensure feed during system leakproofness,
Connection between reaction kettle interface 5, connecting pipe 1 and tank body 2, is added gasket between metal quick coupler 4
7, and it is fixed with metal chuck 8, and good airproof performance, installation is simple, dismantles very convenient.For convenient for control charging rate, it is described
2 bottom of tank body is equipped with controlled valve 3, and the two sides above the tank body 2 are respectively equipped with the access port 9 of inert gas
With pressure relief opening 10, and on access port 9 and pressure relief opening 10 be equipped with controlled valve 11.Solids material position in order to facilitate observation of
It sets, form 12 with a scale is equipped in the middle part of the tank body 2, passes through regulating switch valve 11 and inert gas access port 9
Pressure, realize control to charging rate.
Solid material is added in tank body 2, has fed first under inert gas protection by application method of the invention
Finish and is sealed with chuck blank cover 7；Again connecting pipe 1, tank body 2 are added gasket to 7 between faying face and pass through metal
Chuck 8 is installed on reaction kettle interface 5 as shown in Fig. 2；The controlled valve 3 in connecting pipe 1 is first opened, then is delayed
The slow controlled valve 3 opened on tank body 2, adjusts the air velocity of inert gas access port 9, in gravity and gas pressure
Under the action of, slowly the reacted kettle interface 5 of solid material is added in reaction kettle 13, observes form 12 with a scale, is remembered
Record charging rate；Charging finishes, the controlled valve 3 on closing tank body 2 and connecting pipe 1, rapid removal slack tank body 2,
Another tank body 2 equipped with solid material is installed, it can be achieved that continuous charging again.Entire charging process operation is very square
Just and it is safe, no dust and solvent volatilization phenomenon.
