Description

Technical Field

[0001] This utility model relates to the field of stainless steel reactors, and in particular to a fully insulated stainless steel reactor. Background Technology

[0002] Reactors are pressure vessels used in industries such as chemical, pharmaceutical, and food processing to complete processes such as sulfidation, nitration, hydrogenation, polymerization, and condensation of substances. Their core function is to provide the pressure, temperature, and mixing conditions required for the reaction. Many chemical reactions, such as polyester reactions, require high temperatures; therefore, the thermal insulation performance of the reactor is crucial, directly affecting energy costs, reaction efficiency, and the stability of product quality.

[0003] Currently, most insulated reactors on the market adopt a fixed external insulation layer structure, that is, an insulation material layer wrapped or welded to the outer wall of the reactor. Although this integrated structure has a reasonable insulation effect, it also has obvious drawbacks: when the reactor needs to be cooled down, cleaned or maintained quickly after the reaction is completed, the fixed insulation layer greatly hinders heat dissipation, resulting in a long cooling waiting time, which seriously affects equipment utilization and production rhythm.

[0004] To address the aforementioned issues, existing technologies have introduced openable and closable insulation structures. For example, Chinese utility model patent CN219964860U discloses a polyester reactor with good insulation performance, which employs two sets of symmetrical semi-circular arc-shaped insulation components, driven to open and close by hydraulic push rods. This design achieves a certain degree of switching between insulation and heat dissipation functions. However, this solution still has several shortcomings: First, its insulation components consist of only two large arc plates, resulting in a large overall weight and high power requirements for the drive mechanism. Furthermore, when closed, deformation easily occurs at the joint under thermal stress, leading to poor sealing and heat leakage. Second, the drive mechanism and the insulation plates are rigidly connected. This structure cannot adapt to minor deformations or manufacturing and installation errors that may exist in the reactor body. As a result, when multiple insulation plates are closed, it is difficult to achieve synchronous and uniform contact with the outer wall of the reactor, easily creating gaps, forming thermal bridges, and reducing insulation efficiency. At the same time, rigid contact is prone to mechanical impact and wear at the moment of closure, affecting the lifespan of the equipment. Utility Model Content

[0033] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Please refer to Figures 1 to 2This utility model provides a fully insulated stainless steel reactor, including a base 1, a reactor body 4, insulation plates 3, and a driving mechanism 2. The upper surface of the base 1 is recessed at the center for fixing the reactor body 4. Multiple sliding grooves are arranged in a circular array around the installation groove on the upper surface of the base 1. The insulation plate 3 is slidably installed in each of the sliding grooves. The driving mechanism 2 is disposed in the base 1 and is used to drive each insulation plate 3 to move towards the reactor body 4. The multiple insulation plates 3 form an annular insulation layer on the outer wall of the reactor body 4.

[0035] In use, the driving mechanism 2 moves each insulation plate 3 toward the vessel body 4, forming a ring-shaped insulation layer on the outer wall of the vessel body 4, which has an insulation effect. When the reaction is completed and the vessel body 4 needs to be cooled down, cleaned or maintained quickly, the driving mechanism 2 moves each insulation plate 3 toward the vessel body 4, which can accelerate the heat dissipation on the surface of the vessel body 4 and facilitate the dissipation of heat inside the insulation components, thereby accelerating the heat dissipation effect and facilitating the rapid progress of subsequent work.

[0036] The design of multiple insulation boards 3 makes each insulation board 3 smaller in size, with less absolute deformation due to thermal expansion, resulting in less and more dispersed thermal stress, and thus a better insulation effect of the resulting insulation layer.

[0037] In this embodiment, the driving mechanism 2 includes a slider 25, a connecting rod 24, a lead screw 22, a lifting ring 23, and a control motor 21;

[0038] The slider 25 is slidably installed in the groove, and the insulation board 3 is fixedly installed on the top of the slider 25;

[0039] The base 1 has a control cavity, the lead screw 22 is coaxially arranged with the mounting groove, one end of the lead screw 22 is rotatably connected to the top of the control cavity, and the other end of the lead screw 22 passes through the base 1 and is fixedly connected to the control motor 21.

[0040] The lifting ring 23 is threaded onto the lead screw 22;

[0041] The outer wall of the lifting ring 23 is hinged with multiple connecting rods 24 at equal intervals along its circumference. Each connecting rod 24 corresponds to a heat insulation plate 3. The other end of the connecting rod 24 away from the lifting ring 23 is rotatably connected to a slider 25 corresponding to the bottom of the heat insulation plate 3.

[0042] In use, the motor drives the lead screw 22 to rotate, controlling the lifting ring 23 on the lead screw 22 to move up and down. When the lifting ring 23 moves downward, under the action of the connecting rod 24, it drives the slider 25 in the slide groove to move towards the vessel body 4.

[0043] It should be noted that the bottom of the slide has a strip-shaped movable hole for the movement of the connecting rod 24, and the movable hole is connected to the control cavity.

[0044] refer to Figure 4 In this embodiment, a fixing rod 26 is provided on the top of the slider 25. A buffer groove is provided on the side of the fixing rod 26 facing the insulation board 3. A connecting plate 28 is slidably installed in the buffer groove. The connecting plate 28 is connected to the insulation board 3 through a connecting rod 27. A spring 29 is installed in the buffer groove. One end of the spring 29 is connected to the connecting plate 28, and the other end of the spring 29 is connected to the inner wall of the buffer groove.

[0045] When the insulation plate 3 moves towards the vessel body 4 to enclose and insulate the vessel body 4, the spring 29, connecting plate 28 and connecting rod 27 can ensure that each insulation plate 3 can adaptively and evenly press against the surface of the vessel body 4, improving the insulation effect. Moreover, when the insulation plate 3 closes, it has a buffering effect, reducing the rigid impact on the vessel body 4 and extending the service life of the equipment.

[0046] refer to Figure 3 One end of the insulation board 3 is provided with an outwardly extending wedge 31, and the other end of the insulation board 3 is provided with a connecting groove 32 corresponding to the wedge 31. A sealing strip is installed in the connecting groove 32.

[0047] During the process of adjacent insulation plates 3 closing together, the wedge 31 enters the corresponding connecting groove 32, and together with the sealing strip, the adjacent insulation plates 3 are sealed together, improving the insulation effect on the vessel body 4.

[0048] In this embodiment, the insulation board 3 is made of high-temperature rock wool or ceramic fiber.

[0049] In this embodiment, the vessel body 4 is made of stainless steel.

[0050] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
