Description

Technical Field

[0001] This utility model belongs to the technical field of glass-lined reactors, and specifically relates to a glass-lined cyclization reactor. Background Technology

[0002] Glass-lined reactors play a crucial role in many key industries such as chemical, pharmaceutical, and food industries. However, in most existing glass-lined reactors, the stirring structure and stirring direction are too simple, which cannot accelerate the heating rate of materials while ensuring that the materials are fully mixed and reacted, making it difficult to meet the stringent requirements of modern industrial production for efficient and precise mixing.

[0003] A search revealed that the prior art, patent number CN222219562U, describes a glass-lined reactor with a baffle assembly. The reactor body has two symmetrically shaped grooves on its inner wall. Two through grooves are formed on both sides of each groove. A first connecting strip and a second connecting strip are slidably installed inside each through groove. A fixed shaft is fixedly installed inside each groove, and multiple evenly distributed connectors are slidably installed on the outer walls of each fixed shaft. This prior art stirring device has a single stirring direction, which fails to accelerate the stirring speed of the material while also failing to ensure that the material is fully mixed and reacted, making it difficult to meet the stringent requirements of modern industrial production for efficient and precise mixing.

[0004] Further search revealed a novel glass-lined reaction vessel with coil heating, according to prior art announcement number CN221733285U. This vessel includes a glass-lined reactor, a jacket, an upper coil, a lower coil, and connecting components. However, this prior art lacks a stirring mechanism, relying solely on the upper and lower coils to heat the materials. The lack of a stirring mechanism during heating results in slow heating and prevents uniform mixing of the materials. This makes it difficult for materials of different components to fully contact and react, ultimately leading to incomplete reactions, compromised product quality, and an inability to meet the complex and ever-changing demands of industrial production. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a glass-lined cyclic reaction vessel. The vessel body is heated and kept warm through a jacket, and the material inside the vessel body is heated through a multi-tube heat exchanger. The stirring mechanism not only fully stirs the material but also accelerates the flow of material around the multi-tube heat exchanger, thereby shortening the material heating time and accelerating the reaction rate. This achieves comprehensive and deep mixing of the material inside the entire vessel body.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A glass-lined cyclic reaction vessel includes a vessel body, a jacket, a motor base, a thermometer, a multi-tube heat exchanger, and a stirring mechanism. The top of the vessel body has a feed inlet, and the bottom of the vessel body has a discharge outlet. The motor base is installed on the top of the vessel body, the jacket is welded to the outside of the vessel body, and the thermometer, multi-tube heat exchanger, and stirring mechanism are installed inside the vessel body.

[0008] The jacket has an inlet on one side and an outlet at the bottom.

The main tube at the bottom of the heat exchange tube passes through the bottom of the vessel body and has an air inlet at the bottom.

[0010] The stirring mechanism includes a motor I, a rotating shaft I, a fixed frame I, a fixed frame II, an internal gear ring, a gear I, and a stirring blade I. The fixed frame I is installed on the top of the inner wall of the vessel, the fixed frame II is installed on the bottom of the inner wall of the vessel, the internal gear ring is installed on the fixed frame I, and a limiting ring is provided at the bottom of the internal gear ring.

[0011] The top of the rotating shaft I is provided with a motor compartment. The rotating shaft I is hollow. The motor II is installed in the motor compartment and the rotating shaft II is rotatably installed in the rotating shaft I. The top of the rotating shaft II is fixedly connected to the output shaft of the motor II. The bottom of the rotating shaft II is provided with a reciprocating screw.

The stirring blade II is movably connected to the rotating shaft II through the spiral groove of the reciprocating screw at the bottom of the rotating shaft II.

[0012] The top of the internal gear ring is provided with a protective cover plate, which is fixedly connected to the fixed frame I. The rotating shaft I passes through the middle of the protective cover plate. The protective cover plate is conical in shape to prevent material from accumulating on the top of the protective cover plate and affecting the transmission between the internal gear ring and gear II and gear I.

[0013] A telescopic protective sleeve is provided between the stirring blade II and the fixed frame II. The telescopic protective sleeve is sleeved on the reciprocating screw at the bottom of the rotating shaft II. The top end of the telescopic protective sleeve is fixedly connected to the fixed frame II, and the bottom end of the telescopic protective sleeve is fixedly connected to the stirring blade II.

[0014] The advantages of this utility model compared with the prior art are as follows:

The exhaust gas is discharged from the outlet. The multi-tube heat exchanger significantly improves heating efficiency through the combination design of spiral tubes and multi-tubes. The multi-tubes cover the material in layers to achieve efficient, uniform and low-consumption indirect heating and avoid material contamination.

[0016] 2) Motor I drives rotating shaft I to rotate, which in turn drives gear II on limit plate I to rotate. Through gear I meshing with the internal gear ring, stirring blade I rotates on its own axis and revolves around the center, thus mixing the material in the upper layer of the vessel laterally. While fully mixing the material, it also accelerates the flow of material around the multi-tube heat exchanger, shortens the material heating time, and speeds up the reaction rate of the material. Motor II drives rotating shaft II to rotate, which in turn drives stirring blade II to move up and down along the shaft. Multiple sets of telescopic rods support the stable lifting and lowering of stirring blade II, realizing longitudinal mixing of the lower layer of material. This ensures that the material at the bottom of the vessel is fully mixed, achieving all-round and deep mixing of the material in the entire vessel. Attached Figure Description
