Description

Technical Field

[0001] The utility model relates to the technical field of reactors, in particular to a multi-layer jacketed reactor. Background Art

[0002] A jacketed reactor utilizes a jacket structure for heating or cooling. It typically consists of a reactor body and a jacket. The reactor body holds the reactants, while the jacket tightly wraps around the reactor body, creating an enclosed heating or cooling chamber. The heating or cooling medium (such as steam, water, or oil) within the jacket regulates the internal temperature of the reactor to meet the needs of the chemical reaction.

[0003] The utility model patent with authorization publication number CN221062669U discloses a multi-layer jacketed reactor. The multi-layer jacketed reactor comprises a reactor with a jacket provided on the outside of the reactor, an insulation jacket provided on the outside of the jacket, a metal mesh in close contact with the outside of the insulation jacket, a resin layer coated on the outside of the metal mesh, a protective shell provided on the outside of the resin layer, and corresponding through-holes provided on the insulation jacket, the metal mesh, the resin layer, and the protective shell. The through-holes are each provided with a plug of a matching size. The plug comprises a columnar portion inserted into the through-hole and a pull-out portion positioned outside the through-hole and clamped to the outer wall of the protective shell. One end of the columnar portion abuts against the outer wall of the jacket, and the other end of the columnar portion is rigidly connected to the pull-out portion. The utility model sequentially provides a metal mesh, a resin layer, and a protective shell on the outside of the insulation jacket, thereby improving the strength of the insulation jacket and extending the service life of the protective jacket.

[0004] Although the multi-layer jacketed reactor improves the strength of the insulation jacket, the device still has the following problems during use: during the use of the jacketed reactor, due to the continuous inflow and outflow of the medium, various attachments are often easily formed on the inner wall of the jacket. For example, when hot water circulates through the jacket, it may cause the accumulation of scale. The presence of these attachments not only affects the heat exchange efficiency of the reactor, but may even affect the stability of the reaction process and product quality. However, the design of the jacket makes it difficult to disassemble and assemble after installation, which brings considerable difficulties to cleaning the interior of the jacket. In view of this, we propose a multi-layer jacketed reactor. Utility Model Content

A mounting bracket 3 is installed outside between the first connecting block 11 and the second connecting block 22. The first connecting block 11 and the second connecting block 22 pass through the opening of the mounting bracket 3. A fixing bolt 31 is threadedly connected to the top of the mounting bracket 3, and the fixing bolt 31 passes through the first connecting block 11 and the second connecting block 22.

[0032] In this embodiment, a first protrusion 12 is mounted on the top edge of the first connecting block 11, and a second protrusion 23 is mounted on the bottom edge of the second connecting block 22. Grooves 30 are defined within the upper and lower side walls of the opening of the mounting bracket 3, and the first and second protrusions 12, 23 are slidably connected to the grooves 30.

This design not only improves installation efficiency but also enhances connection stability.

[0033] In this embodiment, the insert ring 25 and the connecting ring 251 are integrally formed, and the insert ring 25 is tightly welded to the jacket 2. The integrally formed insert ring 25 and connecting ring 251 ensure the stability and reliability of the structure, avoid safety hazards caused by loose or broken connections, and ensure the tight connection between the jacket 2 and the housing 1.
