Description

Technical Field

[0001] This utility model relates to the field of reaction vessels, specifically to a reaction vessel for the production of chemical pharmaceuticals. Background Technology

[0002] A chemical reactor is a device used for carrying out chemical reactions, widely used in industries such as chemical engineering, pharmaceuticals, food processing, and metallurgy. It typically consists of a reaction vessel, a heating or cooling system, a stirring device, a sealing device, and an instrumentation system for controlling reaction conditions. The reactor provides a controlled environment for chemical reactions, allowing reactions to occur under specific temperature, pressure, and stirring conditions. The working principle of a chemical reactor is based on the chemical reaction of reactants within a closed container. Through heating, cooling, stirring, and the introduction of gases or liquids, the reactants within the reactor undergo chemical transformation, ultimately producing the target product.

[0003] Typically, high-pressure reactors, jacketed reactors, and some special-purpose reactors are equipped with manholes. Manholes can be used to assist in the periodic cleaning, internal inspection, or maintenance of the reactor. However, in existing reactors, the stirring device is mostly stationary and occupies a large space inside the reactor, leaving little room for personnel to enter and operate. Utility Model Content

The bottom of the vessel body is provided with a discharge pipe. A motor is provided at the top of the vessel body. The output end of the motor is driven by a rotating shaft extending into the interior of the vessel body. A stirring frame is rotatably connected to the outside of the rotating shaft. A sliding sleeve is fitted on the outer sliding rod of the rotating shaft. The bottom end of the sliding sleeve extends into the interior of the vessel body and is rotatably connected to the stirring frame through a rotating rod.

[0007] Furthermore, there are multiple stirring racks, which are distributed circumferentially with respect to the axis of the rotating shaft.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] First embodiment:

[0023] See Figures 1-2 As shown, this utility model provides a reaction vessel for chemical production, including a vessel body 1. The top of the vessel body 1 is connected to a feed pipe 101, a manhole 102, and an inspection pipe 104. The bottom of the vessel body 1 is provided with a discharge pipe 103. A motor 2 is provided at the top of the vessel body 1. The output end of the motor 2 is driven to a rotating shaft 201 that extends into the interior of the vessel body 1. A stirring frame 3 is rotatably connected to the outside of the rotating shaft 201. A sliding sleeve 4 is fitted on the sliding rod outside the rotating shaft 201. The bottom end of the sliding sleeve 4 extends into the interior of the vessel body 1 and is rotatably connected to the stirring frame 3 through a rotating rod 401.

[0024] When the device is in use, the motor 2 drives the rotating shaft 201 to rotate, which in turn drives the stirring rack 3 on the outside of the rotating shaft 201 to rotate. The rotating stirring rack 3 can stir the material in the vessel body 1 and assist the material in the vessel body 1 to react. When it is necessary to manually clean the inside of the vessel body 1, the sliding sleeve 4 is released from the fixing of the rotating shaft 201, so that the sliding sleeve 4 slides on the outside of the rotating shaft 201. Then, the rotating rod 401 at the bottom of the sliding sleeve 4 pushes the stirring rack 3 to rotate, so that the stirring rack 3 is close to the rotating shaft 201. After opening the manhole 102, a person can crawl into the inside of the vessel body 1 through the manhole 102. Since the stirring rack 3 is close to the rotating shaft 201, the inside of the vessel body 1 has a larger working space.

[0025] Furthermore, during use, the height of the sliding sleeve 4 can be adjusted to change the angle of the stirring rack 3, thereby selecting the most suitable stirring angle according to the properties of different materials and reaction requirements. This improves the uniformity and efficiency of stirring, which helps to ensure that the materials are fully mixed during the reaction process and reduces dead zones and uneven reactions.

[0026] Furthermore, the outer wall of the vessel body 1 is provided with a heating layer and a heat insulation layer. The inspection pipe 104 is connected to a sensor module for detecting the internal air pressure and temperature of the vessel body 1. The discharge pipe 103 and the feed pipe 101 are provided with electric control valves for controlling the discharge and feed. The opening of the manhole 102 is connected to a sealing plate by bolts.

[0027] The second embodiment differs from the first embodiment in that:

[0028] There are multiple stirring racks 3, which are distributed circumferentially around the axis of the rotating shaft 201. Multiple stirring racks 3 can be used to stir the materials inside the vessel 1, resulting in better stirring effect inside the vessel 1. Specifically, the stirring rack 3 includes multiple inclined frames 301, which are arranged parallel vertically. A vertical frame 302 is rotatably connected between two adjacent inclined frames 301. The vertical frame 302 is arranged vertically. Multiple inclined frames 301 and multiple vertical frames 302 can form a frame structure. When rotating, the stirring effect of materials inside the vessel 1 is good. Since multiple inclined frames 301 and multiple vertical frames 302 are in a parallel state, the upper inclined frame 301 is rotatably connected to the rotating rod 401, so the rotating rod 401 can push the entire stirring rack 3 to fold or unfold.

[0029] The third embodiment differs from the first embodiment in that:

[0030] The motor 2 is fixedly connected to the vessel body 1 via a portal frame. The high end of the sliding sleeve 4 extends into the inner side of the portal frame and is provided with a convex ring. When the sliding sleeve 4 slides downward outside the rotating shaft 201, the convex ring at the high end of the sliding sleeve 4 forms a ring-shaped limiting structure, which can limit the lowest position of the sliding sleeve 4. Furthermore, the sliding sleeve 4 and the rotating shaft 201 are fixedly connected by bolts.

[0031] In addition, a fixing ring 402 is threadedly connected to the outer side of the sliding sleeve 4. The bottom of the fixing ring 402 is provided with a horizontal rotating bearing. After rotating the fixing ring 402, the height of the fixing ring 402 can be adjusted by means of thread transmission. When the bolt between the sliding sleeve 4 and the rotating shaft 201 is released, the height of the sliding sleeve 4 can be adjusted by rotating the fixing ring 402. The adjustment effect is good and the height of the sliding sleeve 4 can be adjusted and controlled.

[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
