Background
At present, when reation kettle broke the vacuum, the pneumatic main valve of surface nitrogen gas is directly opened, because be vacuum environment in the cauldron, gaseous phase space is great in the cauldron, the nitrogen gas pipe volume is less, can lead to becoming negative pressure environment in the nitrogen gas pipe in the twinkling of an eye, in turn can lead to the fact suck-back to the cauldron next door, because there is the material by door cauldron bottom nitrogen gas pipeline, can make partial high temperature resin suck-back to the cauldron outside in the nitrogen gas pipe and cool off, thereby cause the nitrogen gas pipe to block up, and, in the past need the manual work to close reation kettle's pneumatic main valve and the main valve of nitrogen gas pipe when not using reation kettle, some nitrogen gas of inevitable meeting waste during, thereby increase cost. Therefore, it is necessary to provide a device capable of preventing the backflow of the nitrogen gas pipe and reducing the number of operations by the person.
SUMMERY OF THE UTILITY MODEL
The utility model provides a fat reation kettle nitrogen pipe anti-backflow system that can prevent the nitrogen pipe refluence and can reduce personnel's operation.
In order to solve the above problem, the utility model adopts the following technical scheme:
the utility model provides a resin reation kettle nitrogen pipe anti-backflow system, includes controller, three reation kettle and nitrogen gas pipe, each reation kettle's entry all is connected with a first trachea, and each first tracheal other end is connected respectively on the nitrogen gas pipe, still be equipped with pneumatic main valve on each first trachea, in addition, still be equipped with second trachea and first trachea on each reation kettle and be connected, be equipped with surperficial nitrogen gas pneumatic valve on each first trachea with the tracheal junction of second to between the reation kettle, and each pneumatic main valve, surperficial nitrogen gas pneumatic valve all with controller electric connection. When a certain reaction kettle needs vacuum breaking, the controller can automatically check and close the pneumatic main valves of other reaction kettles, then open the surface nitrogen pneumatic valve of the reaction kettle needing vacuum breaking to supplement nitrogen, and recover the pneumatic main valves of other reaction kettles after vacuum breaking is finished.
Furthermore, a nitrogen main valve is arranged on the nitrogen pipe.
Compared with the prior art, the utility model discloses there is following beneficial effect:
the utility model discloses a controller is connected with the pneumatic main valve and the surperficial nitrogen gas pneumatic valve that each reation kettle corresponds, can realize opening the pneumatic main valve that closes all the other reation kettle in the time of the pneumatic main valve that required broken vacuous reation kettle corresponds when needs broken vacuum to the broken vacuum time of period is very short, consequently can not cause the influence to all the other reation kettle, thereby prevents the nitrogen duct refluence, prevents that the nitrogen duct from blockking up. The utility model discloses can effectually prevent nitrogen gas pipe refluence and can reduce personnel's operation.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, a backflow preventing system for a nitrogen pipe of a resin reaction kettle comprises a controller 5, three reaction kettles 1 and a nitrogen pipe 2, wherein an inlet of each reaction kettle 1 is connected with a first gas pipe 31, the other end of each first gas pipe 31 is connected to the nitrogen pipe 2, each first gas pipe 31 is further provided with a pneumatic main valve 41, in addition, each reaction kettle 1 is further provided with a second gas pipe 32 connected with the first gas pipe 31, a surface nitrogen pneumatic valve 42 is arranged between the joint of each first gas pipe 31 and the second gas pipe 32 and the reaction kettle 1, and each pneumatic main valve 41 and the surface nitrogen pneumatic valve 42 are electrically connected with the controller 5. When a certain reaction kettle 1 needs to be broken, the controller 5 automatically checks and closes the pneumatic main valves 41 of the other reaction kettles 1, then opens the pneumatic main valve 41 of the reaction kettle 1 needing to be broken to supplement nitrogen, and restores the pneumatic main valves 41 of the other reaction kettles 1 after the breaking is finished.
The nitrogen pipe 2 is provided with a nitrogen main valve 51.
When the reaction kettle 1 is vacuumized, the pneumatic valve of the reaction kettle 1 beside the reaction kettle is closed, and then the nitrogen pneumatic valve 42 on the surface of the reaction kettle 1 is opened to supplement nitrogen; after the vacuum breaking is finished, the pneumatic valve of the reaction kettle 1 beside is recovered. The vacuum breaking time is short, so that the nitrogen introduction of other reaction kettles 1 cannot be influenced.
For example, R3 needs to break vacuum R3 in the production process, and the pneumatic main valve 41 is in the open state, and the following actions are performed:
1, checking whether a pneumatic main valve 41 of R1 and R2 is opened or not, closing the pneumatic main valve 41 if the pneumatic main valve 41 is opened, and stopping production and keeping the original state if the pneumatic main valve 41 is in a closed state R1 or R2;
2, opening the R3 surface nitrogen pneumatic valve 42 and supplementing nitrogen to R3;
3, after the vacuum breaking is finished, closing the nitrogen pneumatic valve 42 on the surface of the R3;
and 4, restoring the R1 and R2 pneumatic main valve 41, keeping the opening unchanged if the original state is open, and opening the pneumatic valve if the original state is closed.
The utility model discloses during the use, controller 5 is connected with each pneumatic main valve 41 and each surface nitrogen gas pneumatic valve 42, the condition of the pneumatic main valve 41 of each reation kettle 1 of inspection, will remove required broken vacuum reation kettle 1's pneumatic main valve 41 and close, open simultaneously and need broken vacuum reation kettle 1's surface nitrogen gas pneumatic valve 42 to its input nitrogen gas, broken vacuum is accomplished the back, the broken vacuum reation kettle 1's that has closed surface nitrogen gas pneumatic valve 42, open all the other reation kettle 1's pneumatic main valve 41, thereby prevent nitrogen pipe 2 refluences, prevent nitrogen pipe 2 and block up. The utility model discloses can effectually prevent nitrogen gas pipe 2 refluences and can reduce personnel's operation.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
