Abstract
Description
Technical Field
[0001] This utility model relates to the field of reaction vessel technology, and in particular to a reaction vessel. Background Technology
[0002] Reactors are commonly used containers in industries such as chemical, pharmaceutical, and food processing to complete chemical reactions, mixing, and synthesis processes. The stirring device is one of the core components of a reactor, its function being to ensure uniform mixing of reactants, enhance mass and heat transfer, and guarantee the smooth progress of the reaction. The installation position of the stirring shaft is usually fixed. When fine-tuning of the stirring shaft height is required according to process needs (such as changing different types of impellers, adjusting the depth of the impellers within the reactor) or to address wear on the stirring shaft and bushing, the existing structure often presents significant challenges. Typically, this requires complete disassembly of the drive motor and stirring shaft, or adjustment using complex shim sets, which is cumbersome, time-consuming, labor-intensive, and impacts production efficiency.

[0019] To more clearly illustrate the technical solutions in the embodiments of this utility model, the accompanying drawings used in the description of the embodiments will be briefly introduced below.
[0020] Figure 1 This is a schematic diagram of the internal structure of this utility model. Detailed Implementation
[0021] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0022] A reaction vessel, including
[0023] Tank body 1, which includes tank cavity 11;
[0024] The stirring device 2 includes a fixed bracket 21, an adjusting bracket 22, a stirring motor 23, and a stirring shaft 24 connected to the output end of the stirring motor 23, all mounted on the tank body 1. The adjusting bracket 22 is detachably connected to the fixed bracket 21, and the stirring motor 23 is detachably connected to either the fixed bracket 21 or the adjusting bracket 22. The stirring motor 23 is connected to the fixed bracket 21, or at least one adjusting bracket 22 is connected between the stirring motor 23 and the fixed bracket 21 to adjust the height of the stirring shaft 24.
[0025] The stabilizing mechanism 3 includes a first bushing 31 disposed on the inner side wall of the tank 1 and through which the stirring shaft 24 passes, and a second bushing 32 disposed on the inner bottom surface of the tank 1 and through which the stirring shaft 24 passes.
[0026] This invention provides a reaction vessel that allows for flexible and convenient adjustment of the stirring shaft height by setting a detachable adjustable bracket to adapt to different process requirements. At the same time, by setting bushings on both the upper side wall and the bottom, a stable shaft structure with support at both the upper and lower points is formed, which greatly enhances the operational stability of the stirring shaft, reduces vibration and sway, thereby extending the service life of the equipment and ensuring the stirring effect.
[0027] Furthermore, as a preferred embodiment of this solution and not a limitation, the adjusting bracket 22 is provided with support seats 221 at its upper and lower ends, and the support seats 221 are connected to the fixed bracket 21 or the stirring motor 23 by bolts. The connection method of the support seats and bolts provides a standardized interface, making the installation, disassembly, and addition / reduction of the adjusting bracket simple, quick, and reliable, and facilitating the precise step-like adjustment of the stirring shaft height.
[0028] Furthermore, as a preferred embodiment of this solution and not a limitation, a limiting ring 25 is fixedly provided on the stirring shaft 24. When the stirring motor 23 is connected to the fixed bracket 21, the limiting ring 25 presses against the first bushing 31. The limiting ring cooperates with the first bushing to play a role in axial positioning, effectively preventing the stirring shaft from moving downward due to its own weight or axial force during operation, ensuring a constant working depth of the stirring blades, and reducing axial vibration.
[0029] Furthermore, as a preferred embodiment of this solution and not a limitation, the stirring shaft 24 includes a main shaft 241 and an adjusting shaft 242 connected to the main shaft 241. The adjusting shaft 242 engages with the second bushing 32 and slides axially. This allows the adjusting shaft to slide and rise relative to the bottom second bushing. In this way, when adjusting the overall height of the stirring shaft, the bottom bushing avoids jamming or interference with the stirring shaft, ensuring a smooth height adjustment process.
[0030] Furthermore, as a preferred embodiment of this solution and not a limitation, the main shaft 241 and the adjusting shaft 242 are coaxially arranged, and the diameter of the main shaft 241 is larger than the diameter of the adjusting shaft 242. When the stirring motor 23 is connected to the fixed bracket 21, the shoulder between the main shaft 241 and the adjusting shaft 242 presses against the second bushing 32. Utilizing the shoulder formed by the diameter difference, when the stirring shaft is in its lowest position, it forms axial support with the bottom second bushing, working together with the limiting ring to axially limit the stirring shaft from both upper and lower directions, further enhancing the axial stability and positioning accuracy of the stirring shaft.
[0031] Furthermore, as a preferred embodiment of this solution and not a limitation, the tank 1 is provided with a heating pipe 4, which is spirally wound around the inner wall of the tank 1, with its upper end protruding from the upper part of the tank 1 and its lower end protruding from the lower part of the tank 1. The spiral heating pipe increases the contact area with the reactants, achieving efficient and uniform heating, which is beneficial to the reaction; its top-in, bottom-out connection facilitates the smooth flow of the heating medium (such as steam) and the discharge of condensate, improving heat exchange efficiency.
[0032] Furthermore, as a preferred embodiment of this solution and not a limitation, the tank 1 is provided with cooling pipes 5, which are spirally wound around the outer wall of the tank 1. The spiral cooling pipes on the outer wall achieve external cooling of the tank, providing an effective means of cooling the reactor. The combined internal and external temperature control system (internal heating and external cooling) enables the reactor to respond quickly and accurately to temperature changes during the process.
[0033] Furthermore, as a preferred embodiment of this solution and not a limitation, the stirring shaft 24 is provided with a first stirring blade 26, a second stirring blade 27, and a third stirring blade 28 arranged sequentially from top to bottom. The first stirring blade 26 is inclined vertically, the second stirring blade 27 is S-shaped and curved vertically, and the third stirring blade 28 is inclined forward and backward. By setting multiple layers of stirring blades with different shapes and angles, a complex and three-dimensional mixing flow field can be formed in the tank cavity. The first stirring blade mainly generates axial circulation, the S-shaped structure of the second stirring blade can generate strong shearing and tearing effects, and the third stirring blade mainly generates radial flow. The three work together to achieve all-round and efficient mixing and shearing of the material in the entire tank cavity, avoiding stirring dead zones.
[0034] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the tank 1 includes a heat insulation cavity 12 disposed between the heating pipe 4 and the cooling pipe 5, and a filling port 13 connecting the heat insulation cavity 12 to the outside. The heat insulation cavity physically isolates the internal heating pipe and the external cooling pipe, forming a thermal barrier, effectively reducing heat loss to the cooling system during heating and heat transfer from the outside to the inside during cooling, significantly improving their respective temperature control efficiency and reducing energy consumption. The filling port allows the filling of the heat insulation cavity with heat-insulating or thermally conductive materials (such as aerogel slurry, silicone oil, water, or vacuum) to further enhance its heat insulation or cooling performance.
[0035] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
