Description

Technical Field

[0001] This utility model relates to the fields of pharmaceutical, food, and chemical production technology, and in particular to a spherical kettle. Background Technology

[0002] like Figure 2 As shown, existing spherical reactors generally consist of an inner cylinder, a jacket, and an external insulation layer. However, during use, it has been found that this fully jacketed structure, lacking any internal guide plates, leads to short-circuiting of the heat transfer medium within the jacket, resulting in uneven heat transfer from the jacket to the inner cylinder. In other words, some areas of the inner cylinder overheat, while areas with short circuits remain unheated, significantly reducing the reactor's utilization rate. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to solve the problem of low utilization rate of spherical kettles in the prior art, this utility model provides a spherical kettle, which can solve the problem of short circuit of heat medium by making the heat medium flow in a predetermined direction, and greatly improve the utilization rate of the spherical kettle.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a spherical kettle, including a spherical kettle body, a semi-pipe jacket arranged around the outer periphery of the spherical kettle body, an annular channel for the flow of heating medium inside the semi-pipe jacket, and a heat insulation layer provided on the outer side of the spherical kettle body, the heat insulation layer being arranged from top to bottom along the surface of the spherical kettle body and covering the semi-pipe jacket inside.

[0005] Furthermore, in order to ensure that the heat medium inside the semi-pipe jacket can fully pass through the surface of the spherical vessel body, the semi-pipe jacket extends from the upper middle part of the spherical vessel body to the lower part of the spherical vessel body.

[0006] Furthermore, in order to increase the contact area between the semi-tube jacket and the spherical vessel, the semi-tube jacket covers 1 / 2 to 2 / 3 of the surface area of ​​the spherical vessel body.

[0007] Furthermore, in order to ensure the sealing performance of the semi-pipe jacket, the semi-pipe jacket is welded to the spherical vessel body as a whole.

[0008] Furthermore, the semi-tube jacket is formed by a semi-circular tube, angle iron shape, or C-shaped steel roller.

[0009] Furthermore, in order to provide a flow path for the heat medium, the half-pipe jacket is also connected to a heat medium inlet pipe and a heat medium outlet pipe, which pass through the insulation layer.

[0010] Furthermore, to prevent burns from the half-tube jacket, the insulation layer extends from above the half-tube jacket to below it on the spherical vessel body.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The spherical reactor of this utility model controls the flow direction of the heat medium through a semi-pipe jacket, avoiding short circuits of the heat medium, ensuring that the reactor body is fully heated, and improving the utilization rate of the reactor.

[0013] 2. In this utility model of spherical vessel, the half-tube jacket covers at least half of the vessel body to ensure heat exchange efficiency. By covering the half-tube jacket with an insulation layer, burns to personnel from the half-tube jacket are prevented, thus improving safety. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0019] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] like Figure 1 As shown, a spherical vessel includes a vessel body 1, with a semi-tube jacket 2 arranged around its outer periphery. The semi-tube jacket 2 contains an annular channel 21 for the flow of heating medium. The jacket is formed by a semi-circular tube, angle iron, or C-shaped steel roller. The semi-tube jacket 2 is welded to the vessel body 1 as a single unit. This structure ensures the sealing of the annular channel 21, preventing heating medium leakage, and is simple and low-cost. Components such as thermometers, sight glasses, cleaning balls, inlet / outlet ports, vent ports, and other functional ports on the vessel body 1 are not shown in the diagram; these are conventional structures and will not be described further.

[0022] The semi-pipe jacket 2 is also connected to a heat medium inlet pipe and a heat medium outlet pipe. The heat medium flows in from the heat medium inlet pipe and flows along the annular channel 21 to the heat medium outlet pipe. Since the semi-pipe jacket 2 is arranged around the surface of the spherical vessel body 1, the flow direction of the heat medium is limited, so that the heat medium flows along the annular channel 21, ensuring that the heat medium is in full contact with the spherical vessel body 1 and preventing short circuit of the heat medium.

[0023] The semi-tube jacket 2 extends from the upper middle part of the spherical vessel body 1 to the lower part of the spherical vessel body 1. The semi-tube jacket 2 covers 1 / 2 to 2 / 3 of the surface area of ​​the spherical vessel body 1. The semi-tube jacket 2 covers at least the general surface of the spherical vessel body 1, which fully increases the heating area of ​​the spherical vessel and ensures the heat exchange effect.

[0024] An insulation layer 3 is also provided on the outside of the spherical vessel body 1. The insulation layer 3 is arranged from top to bottom along the surface of the spherical vessel body 1 and covers the half-pipe jacket 2 inside. The insulation layer 3 completely covers the half-pipe jacket 2 to avoid the problem of the half-pipe jacket 2 being exposed and causing high temperature burns to the staff. At the same time, the insulation layer 3 also wraps around a part of the spherical vessel body 1 to avoid reducing the heat flow of the spherical vessel body 1 to the outside and to ensure the temperature of the spherical vessel body 1.

[0025] In summary, this novel spherical reactor solves the problem of short-circuiting of the heat medium by allowing the heat medium to flow in a predetermined direction, thus greatly improving the utilization rate of the spherical reactor.

[0026] The above description is based on the preferred embodiments of this utility model. Through the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined by the scope of the claims.
