Description

Technical Field

[0001] This utility model relates to the field of reactor cooling technology, and more specifically to a cooling device for a stainless steel glass-lined reactor. Background Technology

[0002] Stainless steel glass-lined reactors are a commonly used type of chemical equipment. They combine the robustness of stainless steel with the corrosion resistance of glass. The reactor consists of an inner and an outer layer. The inner layer is a glass-lined layer, formed by high-temperature firing of silicon-containing ceramic enamel onto the metal surface to create a dense enamel surface with excellent corrosion resistance. The outer layer is a stainless steel layer, typically made of 304 or 316L stainless steel, which has a robust structure and excellent heat resistance. The stainless steel glass-lined reactor can be cooled by methods such as cooling water circulation, adding refrigerant, and ice baths, allowing the media inside the reactor to react fully.

[0003] The shortcomings of existing technologies: In existing stainless steel glass-lined reactor equipment, most of them can be cooled by circulating cooling water. However, this requires the use of coolers, water pumps and other external driving sources to circulate cooling water for cooling operations. This requires driving multiple independent driving sources at the same time, which increases energy consumption, increases equipment maintenance costs, reduces equipment lifespan, and is not conducive to practical application and operation.

[0023] The following will be combined with the appendix Figure 1 To be continued Figure 4 The technical solutions in the embodiments of this utility model are clearly and completely described. 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 embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0024] Please see Figure 1-4 This utility model embodiment provides a cooling device for a stainless steel glass-lined reactor, used to cool the stainless steel glass-lined reactor 1, comprising:

[0025] The spiral tube (17) is installed in the jacket of the stainless steel glass-lined reactor (1);

[0026] The forced circulation mechanism has its inlet and outlet ends connected to the spiral tube (17) and the water tank (20) respectively via pipes. A water chiller (19) is also installed on the top of the water tank (20), and the spiral tube (17) is also connected to the water tank (20).

[0027] The forced circulation mechanism includes a C-shaped plate (2), a pressure box (14), and a piston (18). The C-shaped plate (2) is fixedly installed on the outside of the stainless steel glass-lined reactor (1). The pressure box (14) is fixedly installed on the top of the outside of the C-shaped plate (2). The piston (18) is slidably connected inside the pressure box (14). The liquid inlet and liquid outlet are set on the pressure box (14). A one-way valve is provided in both the liquid inlet and liquid outlet.

[0028] In practical application, the piston 18 in the forced circulation mechanism reciprocates. During this process, the water in the pressure tank 14 is first forced to be discharged into the spiral tube 17, so that the water passes through the spiral tube 17 and exchanges heat with the stainless steel glass-lined reactor 1 and the materials inside, thus cooling them down. After the heat exchange, the water enters the water tank 20. Then, the piston 18 moves in the opposite direction, so that the pressure tank 14 is in a negative pressure state. At this time, the water in the water tank 20 is forcibly drawn into the pressure tank 14 and also passes through the water chiller 19, exchanging heat with external media such as air. This cycle repeats, thus cooling the stainless steel glass-lined reactor 1 and the materials inside.

[0029] This embodiment achieves efficient energy transfer and utilization by driving a forced circulation mechanism, which uses a single drive source to rotate multiple mechanisms. This further cools the stainless steel glass-lined reactor 1 and the medium inside the reactor 1, avoiding energy waste caused by multiple independent drive sources. Compared with ordinary water circulation cooling, it is more effective, reduces maintenance costs, and improves the overall reliability and service life of the equipment.

[0030] In one embodiment, the spiral tube 17 can be made of copper, which provides better heat exchange.

[0031] Please see Figure 1-4 As a preferred embodiment of the present invention, the forced circulation mechanism further includes an L-shaped plate (4), a connecting rod (8), a reciprocating screw (13) and a U-shaped limiting plate (16). The U-shaped limiting plate (16) and the reciprocating screw (13) form a helical pair transmission. The reciprocating screw (13) is connected to the servo motor (5) through the first transmission mechanism. The servo motor (5) is mounted on the stainless steel glass-lined reactor (1) through the L-shaped plate (4). The U-shaped limiting plate (16) and the piston (18) are fixedly connected through the connecting rod (8).

[0032] In practical application, the servo motor 5 drives the reciprocating screw 13 to rotate through the first transmission mechanism. Under the action of the screw pair, the U-shaped limiting plate 16 can drive the piston 18 to reciprocate, thereby realizing the forced drainage and suction functions.

[0033] Please see Figure 1-4 As another preferred embodiment of the present invention, the U-shaped limiting plate (16) is slidably coupled with the pressure box (14), and the pressure box (14) is provided with a limiting groove (15) for limiting the stroke of the U-shaped limiting plate (16).

[0034] In this embodiment, the pressure box 14 is provided with a limiting groove 15 for limiting the travel of the U-shaped limiting plate 16. The purpose is to restrict the movement of the U-shaped limiting plate 16 to ensure the safety of use.

[0035] Please see Figure 1-4 As another preferred embodiment of the present invention, the stainless steel glass-lined reactor (1) is also equipped with a plurality of stirring rods (7), each of the stirring rods (7) being fixed on a first rotating shaft (6), and the first rotating shaft (6) being connected to a servo motor (5) through a second transmission mechanism.

[0036] In this embodiment, the stirring rod 7 is generally an inherent component inside the stainless steel glass-lined reactor 1. If there is no corresponding stirring rod 7 in the stainless steel glass-lined reactor 1, it can be added separately. Its advantage is that while improving the stirring and material reaction effect, it can also improve the heat exchange efficiency with the water in the spiral tube 17, thereby improving the cooling effect.

[0037] In one embodiment, the structure of the stirring rod 7 can be varied, such as a rod-shaped structure or a plate-shaped structure, as long as it can achieve stirring or agitation of the material. This embodiment does not impose any additional limitations here.

[0038] Please see Figure 1-4 In another preferred embodiment of this utility model, the first transmission mechanism includes a fixed plate (3), a second rotating shaft (9), and pulleys (12). The fixed plate (3) is fixedly installed on the top of the stainless steel glass-lined reactor (1). The second rotating shaft (9) is rotatably connected inside the fixed plate (3). The pulleys (12) are respectively fixed to the shaft ends of the second rotating shaft (9) and the reciprocating lead screw (13). The two pulleys (12) are connected by a synchronous belt drive. Further, the second transmission mechanism includes a first bevel gear (10) and a second bevel gear (11) that mesh with each other. The first bevel gear (10) is fixedly installed on the second rotating shaft (9), and the second bevel gear (11) is fixed on the first rotating shaft (6).

[0039] In practical application, the power output by the servo motor 5 is transmitted to the first rotating shaft 6 to rotate the stirring rod 7, thereby improving the heat exchange effect between the material and the water in the spiral tube 17. On the other hand, the power is transmitted through the bevel gear set to drive the second rotating shaft 9 to rotate, thereby determining the rotation of the reciprocating screw 13 to realize the reciprocating motion of the piston, thus achieving the forced liquid suction and discharge effect.

[0040] Based on the explanations and teachings in the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and any modifications and alterations to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
