Embodiment 1

[0024] The technical scheme adopted in the present invention is as follows: a temperature-controllable reactor, comprising a support frame 1 with a buffering effect, a kettle body 2 arranged on the support frame 1, a stirring device 3 arranged on the center line of the kettle body 2, a set The feed port 4 on the upper part of the still body 2 and the discharge port 5 arranged on the lower part of the still body 2 also include a first spiral oil bath pipe 6 and a second spiral oil bath pipe 7, and the still body 2 includes an outer layer kettle Body 8 and inner layer kettle body 9, a cooling water tank 10 is formed between the outer layer kettle body 8 and the inner layer kettle body 9, the upper part of the outer layer kettle body 8 is provided with a cooling water outlet 11 and the lower part is provided with a cooling water outlet The inlet 12, the cooling water outlet 11 and the cooling water inlet 12 are respectively provided with a first valve 13, and a vertical first spir...

Embodiment 2

[0027] On the basis of Example 1, the stirring device 3 includes two cylinders 21 and a stirring shaft 22 arranged inside the inner kettle body 9, and a crossbeam 23 is provided on the top of the outer kettle body 8, and the stirring shaft 22 extends to the outer end of the outer kettle body 8 and is fixed on the crossbeam 23, and the top wall of the outer kettle body 8 on both sides of the stirring shaft 22 is respectively provided with cylinders 21, and the cylinders 21 are connected by the shrink rod 24 and The beams 23 are connected, and the stirring shaft 22 is provided with a plurality of circular stirring blades 25 . The cylinder 21 promotes the up and down movement of the telescopic rod, the telescopic rod drives the stirring shaft 22 to move up and down in the inner kettle body 9, and the stirring shaft 22 drives the circular stirring blade 25 to move, which can realize sufficient stirring of the reactants.

[0028] Further, each of the circular stirring blades 25 is ...

Embodiment 3

[0030] On the basis of Embodiment 1, 3-5 buffer blocks 27 are arranged inside the support frame 1 . 3 to 5 buffer blocks 27 are arranged inside the support frame 1 to reduce the vibration of the reactor.

Abstract

The invention discloses a temperature-controllable reaction kettle. The reaction kettle comprises a support frame with a buffering effect, a kettle body arranged on the support frame, a stirring device arranged on a center line of the kettle body, a feeding opening formed in the upper part of the kettle body, a discharging opening formed in the lower part of the kettle body, a first spiral oil bath pipe and a second spiral oil bath pipe, wherein the kettle body comprises an outer-layer kettle body and an inner-layer kettle body; a cooling water tank is formed between the outer-layer kettle body and the inner-layer kettle body; a temperature sensor is arranged in the inner-layer kettle body. According to the temperature-controllable reaction kettle, oil bath flowing directions of the firstspiral oil bath pipe and the second spiral oil bath pipe are opposite, so that reactants in the reaction kettle can be uniformly heated; through adoption of the cooling water tank, the first spiral oil bath pipe and the second spiral oil bath pipe can be used for heating, the reactants can be heated and can also be used for cooling the mixture in the reaction process also can be cooled; the dual accurate temperature control of the inside and the outside of polymerization reaction is achieved.

Description

technical field [0001] The invention relates to a reaction kettle, in particular to a temperature-controllable reaction kettle. Background technique [0002] Reactors are widely used in petroleum, chemical, rubber, pesticides, dyes, medicine, food, pressure vessels used to complete vulcanization, nitration, hydrogenation, alkylation, polymerization, condensation and other processes. [0003] At present, the synthetic method of polymer generally adopts to put several kinds of polymer reaction monomers into the reactor to carry out polymerization reaction at the same time. Polymer reaction monomers will absorb heat or exotherm during the polymerization reaction, and temperature control has a great effect on the selectivity and yield of reaction substances. During the reaction process of the polymer reaction monomer, the temperature needs to be raised to induce the reaction at the beginning, and a large amount of heat is released after entering the reaction process, and the he...
