Abstract
The utility model relates to nylon polymerization equipment, in particular to a novel high-temperature high-pressure polymerization reaction kettle. The reaction kettle comprises a reaction kettle body, wherein a high-temperature and high-pressure resistant feeding storage tank is arranged on the reaction kettle body. As the existing reaction kettle has no way to add new materials in the prepolymerization stage and the final polymerization stage, the reaction kettle lacks maneuverability and diversity of test means. According to the utility model, a temperature-resistant pressure-resistant feeding storage tank is additionally arranged on the reaction kettle, so that more various reaction forms are provided for a polymerization test.
Description
Technical Field
The utility model relates to nylon polymerization equipment, in particular to a novel high-temperature high-pressure polymerization reaction kettle.
Background
The high-temperature high-pressure polymerization reaction kettle is main equipment for an intermittent modified nylon material polymerization pilot test, and mainly comprises a kettle body, a jacket, a high-temperature resistant discharge valve, a casting belt head, a magnetic stirrer and a mold temperature machine set. The heat conducting oil is circularly heated in the jacket and the die temperature unit to provide heat required by the reaction for the reaction kettle, and the kettle is kept at high pressure during the reaction, so that once the reaction is started, the kettle body must be completely sealed, and the pressure can be released and the material can be discharged until the reaction is finished. Therefore, in the prepolymerization stage and the final polymerization stage, no new material is added, and the maneuverability and the diversity of test means are lacked.

The utility model aims to solve the technical problem of providing a novel high-temperature high-pressure polymerization reaction kettle to increase the reaction diversity.
The utility model is realized in the following way:
the utility model provides a novel high temperature high pressure polymerization reation kettle, includes the reation kettle body, set up a high temperature resistant highly compressed feeding storage tank on the reation kettle body.
Further:
the feeding storage tank with the reation kettle body passes through the inlet pipe and connects, be equipped with feed valve on the inlet pipe.
The feeding storage tank comprises a tank body and a top cover which are detachably connected, a nitrogen inlet and a nitrogen outlet are respectively arranged on the top cover, and the tank body is provided with a jacket.
The reaction kettle body and the jacket on the feeding storage tank are both connected with the mold temperature unit.
The mould temperature unit is used for realizing the temperature control of the reaction kettle and the storage tank, and is conventional equipment in the field.
And at least one of a temperature sensor and a pressure sensor is arranged on the feeding storage tank.
The utility model has the advantages that: a temperature-resistant pressure-resistant feeding storage tank is added, so that more various reaction forms are provided for a polymerization test.
Drawings
The utility model will be further described with reference to the following examples with reference to the accompanying drawings.
FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
Referring to fig. 1, a novel high-temperature high-pressure polymerization reactor according to the present invention comprises: the system comprises a reaction kettle system 1, a mold temperature unit 2 and a temperature-pressure-resistant feeding storage tank system 3. Wherein the reaction kettle system 1 comprises a kettle body, a kettle jacket, a discharge valve, a casting belt head, a magnetic stirrer, a temperature and pressure instrument and the like (conventional devices); the mould temperature unit 2 provides components (conventional devices) such as a pipeline, a head tank, a circulating pump and the like; the temperature and pressure resistant feeding storage tank system 3 comprises a temperature and pressure resistant storage tank 31, a storage tank jacket 32, a feeding valve 33, a nitrogen inlet, a nitrogen outlet, a corresponding valve, a temperature and pressure instrument and the like.
The temperature and pressure resistant storage tank 31 comprises a tank body 311 and a top cover 312 which are detachably connected (connected through a bolt fastening assembly), the temperature and pressure resistant storage tank 31 is directly connected to the inside of the kettle body through a pipeline, the storage tank 31 is arranged above the kettle body, and the storage tank jacket 32 is heated by circulating heat conduction oil of a mold temperature machine. Through addding temperature-resistant pressure storage tank, after sealing the polymeric kettle body, this storage tank 31 can also provide the feeding. At the stage of the neutralization reaction, it is possible to try to add new materials, increasing the diversity of the reaction.
The specific operation steps are as follows: the top cover 312 of the storage tank is opened, raw materials needing reaction are added, the top cover 312 is covered and screws are tightened, meanwhile, nitrogen is required to be opened for strictly deoxidizing, and if heating is required, the mold temperature machine is opened for circular heating. When the reaction kettle is in a specific stage, the feeding valve 33 of the storage tank 31 is opened for feeding, and the feeding valve is closed after the feeding is finished, so that the whole operation is completed.
Although specific embodiments of the utility model have been described above, it will be understood by those skilled in the art that the specific embodiments described are illustrative only and are not limiting upon the scope of the utility model, and that equivalent modifications and variations can be made by those skilled in the art without departing from the spirit of the utility model, which is to be limited only by the appended claims.
