Description

Technical Field

[0001] The utility model belongs to the technical field of chemical equipment jackets, and in particular relates to a novel wrapping tube component of a spiral flow-guiding jacket. Background Art

[0002] With the continuous development of heat exchange technology, the requirements for heat exchange effects of equipment such as stirred tanks are getting higher and higher. Setting spiral guide plates in jackets has always been one of the most effective solutions to enhance the heat exchange effects of equipment such as stirred tanks. The spiral guide plates belong to spiral baffle structures, and their purpose is to guide the fluid to flow along a spiral path, reducing fluid resistance while enhancing fluid mixing and heat transfer. Compared with traditional jacket structures, they have higher heat exchange efficiency and better heat exchange uniformity.

[0003] However, the existing wrapping cylinder assembly has the problem of short-circuit leakage. According to the GB / T 151-2014 heat exchanger design regulations, the gap between the outer diameter of the baffle and the cylinder varies from 3 to 20 mm. The leakage caused by this gap will greatly reduce the heat exchange effect of the equipment, seriously reduce the heat exchange effect of the stirred tank jacket and destroy the heat exchange uniformity; a part of the fluid is not affected by the guide of the spiral guide plate, and continuously flows into the gap between the spiral guide plate and the cylinder. This part of the fluid flows out along the inner wall of the jacket and does not fully exchange heat with the wall of the equipment that needs heat exchange, causing heat loss. It will also cause the temperature of the inner wall of the jacket to be too high, increase the production requirements of the jacket material, cause material waste, and lead to an increase in the production cost of the jacket. For this reason, we propose a wrapping cylinder assembly for a new spiral guide jacket. Utility Model Content

[0004] The utility model aims to provide a novel wrapping tube assembly of a spiral guide jacket to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of wrapping cylinder assembly of a spiral guide jacket, comprising a wrapping cylinder arranged between a container shell and a jacket cylinder, a spiral guide plate is arranged on the outer peripheral side of the container shell corresponding to the inner side of the wrapping cylinder, and the inner and outer sides of the spiral guide plate are tightly connected to the container shell and the wrapping cylinder respectively, so that a spiral guide channel is formed between the container shell, the jacket cylinder, the wrapping cylinder and the spiral guide plate.

[0006] Preferably, the upper and lower parts of the dressing cylinder are respectively provided with an upper cone section and a lower cone section, and the upper cone section, the lower cone section and the dressing cylinder are an integrally formed structure.

[0007] Preferably, the edge of the upper cone section is not connected to the inner side wall of the jacket cylinder.

[0008] Preferably, the edge of the lower cone section is welded to the inner side wall of the jacket cylinder.

[0009] Preferably, at least one drain hole is provided on the lower cone section.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. In the utility model, the wrapped cylinder is tightly wrapped on the outer peripheral side of the spiral guide plate, so that the wrapped cylinder, the spiral guide plate and the container shell are tightly connected, and the connection gap between the inner and outer edges of the spiral guide plate is eliminated, so that a spiral guide channel is formed between the container shell, the jacket cylinder, the wrapped cylinder and the spiral guide plate. The spiral guide channel strengthens the guide effect, solves the short-circuit leakage problem existing in the traditional jacket structure, and avoids the heat loss of part of the fluid caused by the connection gap of the spiral guide plate. It has stronger heat exchange efficiency and heat exchange uniformity than the traditional jacket structure, reduces the jacket structure manufacturing temperature requirement, saves materials and reduces production costs;

[0012] 2. The utility model has at least one drain hole on the lower cone section. Since the upper cone section is not connected to the inner wall of the jacket cylinder, the heat exchange medium will enter between the wrapping cylinder and the jacket cylinder and can be discharged through the drain hole to avoid the accumulation of heat exchange medium and the problem of excessively high temperature on the inner side of the jacket cylinder, thereby avoiding damage to the equipment.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-Figure 2 The utility model provides a new type of wrapping cylinder assembly of a spiral guide jacket, comprising a wrapping cylinder 3 arranged between a container shell 1 and a jacket cylinder 2, a spiral guide plate 4 is arranged on the outer peripheral side of the container shell 1 corresponding to the inner side of the wrapping cylinder 3, and the inner and outer sides of the spiral guide plate 4 are tightly connected to the container shell 1 and the wrapping cylinder 3 respectively, so that a spiral guide channel is formed between the container shell 1, the jacket cylinder 2, the wrapping cylinder 3 and the spiral guide plate 4.

[0020] In the utility model, the wrapping cylinder 3 is tightly wrapped around the outer peripheral side of the spiral guide plate 4, so that the wrapping cylinder 3, the spiral guide plate 4 and the container shell 1 are tightly connected, and the connection gap between the inner and outer edges of the spiral guide plate 4 is eliminated, so that a spiral guide channel is formed between the container shell 1, the jacket cylinder 2, the wrapping cylinder 3 and the spiral guide plate 4. The spiral guide channel strengthens the guide effect, solves the short-circuit leakage problem existing in the traditional jacket structure, and avoids the heat loss of part of the fluid caused by the connection gap of the spiral guide plate 4. Compared with the traditional jacket structure, it has stronger heat exchange efficiency and heat exchange uniformity, reduces the jacket structure manufacturing temperature requirement, saves materials and reduces production costs;

[0021] like Figure 3 and Figure 4 As shown, Figure 3 This is a simulation diagram of the fluid cross section of the traditional jacket structure. Figure 4 This is a simulation diagram of the fluid cross section of the reinforced spiral guide jacket structure of the dressing tube assembly of the utility model. Figure 3 and Figure 4 The same type of stirred tank equipment using the traditional jacket structure and the enhanced spiral guide jacket structure of the wrapping tube assembly of the utility model verifies the guide effect of the present invention. Figure 3 and Figure 4 It can be seen that under the same operating conditions of the chemical equipment, the heat exchange medium fluid no longer passes through the gap to cause short circuit by adopting the enhanced spiral guide jacket structure of the wrapping tube assembly of the utility model;

[0022] As shown in Table 1 below, Figure 3 and Figure 4 The comparison table of temperature changes of the heat exchange medium at the inlet and outlet of the stirred tank is shown below:

[0023] Table 1:

[0024]

[0025] It can be seen from Table 1 above that after adopting the enhanced spiral guide jacket structure of the wrapping tube assembly of the utility model, the outlet temperature drops significantly. Compared with the traditional jacket structure, the outlet temperature is reduced by 7°C, nearly 7 percentage points, which directly proves that the heat exchange effect of the enhanced spiral guide jacket structure of the wrapping tube assembly is much better than that of the traditional jacket structure.

[0026] In this embodiment, Figure 1 and Figure 2 As shown, the upper and lower parts of the wrapping cylinder 3 are respectively provided with an upper cone section 301 and a lower cone section 302, the upper cone section 301, the lower cone section 302 and the wrapping cylinder 3 are an integrally formed structure, the edge of the upper cone section 301 is not connected to the inner wall of the jacket cylinder 2, the edge of the lower cone section 302 is welded to the inner wall of the jacket cylinder 2, and at least one drain hole 5 is opened on the lower cone section 302.

[0027] The utility model is provided with at least one drain hole 5 on the lower cone section 302. Since the upper cone section 301 is not connected to the inner wall of the jacket cylinder 2, the heat exchange medium will enter between the wrapping cylinder 3 and the jacket cylinder 2 and can be discharged through the drain hole 5, thereby avoiding the problem of heat exchange medium accumulation and excessively high temperature concentration on the inner side of the jacket cylinder 2, thereby avoiding damage to the equipment.
