Problems solved by technology

[0004] However, the reaction kettle in the prior art has an uneven temperature distribution of the materials in the kettle. The temperature of the materials on the side close to the kettle wall is high, while the temperature of the materials on the side far away from the kettle wall is low. For the kettle body with a relatively small length and diameter, this The phenomenon is more serious, which affects the conversion rate of polymerized monomers

Embodiment 1

[0023] See Figure 1-3 , An accurate temperature control reactor, comprising a drive motor 11, a bearing seat 13, a rotating shaft (23), a stirring paddle (27) and a kettle body (30), the kettle body (30) is a hollow cylinder Shaped cylinder, the bottom of which is fixedly connected to a hemispherical head with straight edges, the upper part of the main body (30) is fixedly connected with a body flange (16), and the upper part of the body flange (16) A threaded hole matched with the bolt is opened, and an upper cap 14 of the autoclave is arranged above the main body (30) of the autoclave, and the upper cap 14 of the autoclave has a hemispherical shape as a whole and is fixedly connected to the bottom of the autoclave. A head flange (21), the head flange (21) is provided with a through hole matching the bolts, and the head 14 on the kettle body and the kettle body (30) pass between The fastening component (15) realizes a detachable connection. The fastening component (15) inclu...

Embodiment 2

[0029] This example is a further limitation and improvement of Example 1 on the basis of Example 1. A temperature-controlled reactor includes all the technical features in Example 1. In addition, as a further solution of this example : In order to facilitate the support and fixation of the kettle body (30) in this embodiment, two supports (18) are arranged on the side wall of the heating jacket (20), the supports (18) are symmetrical It is arranged on both sides of the heating jacket (20) and is fixedly connected to the heating jacket (20).

[0030] As a further solution of this embodiment: in order to improve the accuracy of temperature measurement in this embodiment and to measure the temperature of materials at different positions, there are three temperature measuring elements (29), which are evenly and equidistantly arranged on the heating The left side of the jacket (20).

[0031] As a further solution of this embodiment: the temperature measuring element (29) and the jacket...

Abstract

The invention discloses a reaction kettle with accurate temperature control. The reaction kettle comprises a driving motor, a bearing pedestal, a rotating shaft, a stirring paddle and a kettle body, and a heating ring is arranged in the main shaft heating cavity. Three temperature measuring elements which are uniformly arranged on the outer side of a heating jacket at equal intervals are used forcarrying out multi-point real-time monitoring on the temperature of a material in the kettle body; the heating jacket arranged on the outer side of the kettle body is used for heating and preserving heat of materials in the kettle body from the outer side; meanwhile, the main shaft heating cavity is formed in the rotating shaft arranged in the kettle body; the heating ring is arranged in the heating cavity and is filled with heat conduction liquid; materials are heated from the interior of the materials through the rotating shaft, meanwhile, the materials are stirred under the action of the stirring blade, so that the materials are heated more uniformly, the phenomenon that the temperature of the materials is not distributed uniformly is avoided, and the material temperature control precision of the device is improved.

Description

Technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a reactor with precise temperature control. Background technique [0002] The reactor is a container with physical or chemical reaction. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are realized. [0003] Reactors are widely used in petroleum, chemical, rubber, pesticides, dyes, medicines, and foods. They are used to complete vulcanization, nitrification, hydrogenation, alkylation, polymerization, condensation and other process pressure vessels, such as reactors, reactors, decomposition pots , Polymerizer, etc.; materials generally include carbon-manganese steel, stainless steel, zirconium, nickel-based (Hastelloy, Monel, Inconel) alloys and other composite materials. [0004] However, in the reaction kettle in the prior art, the temperature distribution of t...
