Description

Technical Field

[0001] This application relates to the field of reaction vessel technology, and in particular to a temperature control device for a reaction vessel. Background Technology

[0002] The operation of a reaction vessel is based on the physical or chemical changes that occur in materials under specific conditions. First, the reactants are added to the reaction vessel in a certain proportion and order, and then a stirring device is used to thoroughly mix the reactants and promote the reaction.

[0003] In related technologies, heating or cooling is usually required during the mixing process in a reactor. Typically, a heating coil is installed on the outer wall of the reactor, and a medium is introduced into the heating coil to heat the materials inside the reactor. However, in addition to heating the reactor through the side wall, the heating coil itself also loses heat outside the reactor, resulting in heat waste. Utility Model Content

[0004] The purpose of this application is to address the aforementioned problems existing in the prior art by proposing a temperature control device for a reaction vessel.

[0005] This application can be achieved through the following technical solution: a temperature regulating device for a reaction vessel, including a cooling coil passing through the reaction vessel and a heating coil wrapped around the outer wall of the reaction vessel, wherein a heat insulation layer is installed on the outer wall of the reaction vessel, the heat insulation layer can abut against the surface of the heating coil away from the outer wall of the reaction vessel and is fixed to the outer wall of the reaction vessel by a connector.

[0006] In the above technical solution, when it is necessary to cool the material in the reactor, cold water or other substances can be introduced into the cooling coil to cool the material in the reactor. When it is necessary to heat the material in the reactor, steam or other substances can be introduced into the heating coil through the side wall of the reactor to heat the material in the reactor. The heat insulation layer can reduce the heat loss emitted by the heating coil.

[0007] Furthermore, it also includes a stirring device for stirring materials in the reactor. The stirring device includes a rotary motor installed on the reactor, a stirring shaft installed on the output end of the rotary motor, and several stirring paddles provided on the stirring shaft. The axis of the stirring shaft is arranged to coincide with the axis of the heating coil.

[0008] In the above technical solution, the rotating motor drives the rotating shaft to rotate, and the rotation of the rotating shaft can drive the stirring paddle to stir the materials in the reaction vessel.

[0009] Furthermore, the connector is made of tearable adhesive.

[0010] In the above technical solution, by setting a tearable adhesive, the insulation layer can be easily replaced when it is damaged by external force.

[0011] Furthermore, the stirring paddle includes a paddle plate, an arc plate formed at one end of the paddle plate along its length, and two connecting plates, each of which is formed at one end of the arc plate along its length, and the connecting plates are provided with connecting holes.

[0012] In the above technical solution, the arc plates of the two stirring paddles are both attached to the axial outer wall of the stirring shaft, and then the two oppositely arranged connecting plates are connected by bolts and nuts. At this time, the stirring paddles can be fixed in position relative to the stirring shaft due to friction.

[0013] Furthermore, it also includes a container with an opening at the top of the reactor. The container is arranged around the rotating motor and its outer wall is attached to the rotating motor. The container is equipped with a cooling component that can cool the rotating motor. A drain valve is provided on the side wall of the container.

[0014] In the above technical solution, the rotating motor will get hot after prolonged use. By setting up a container, the staff can put ice or cold water in the container to cool down the rotating motor.

[0015] Furthermore, it also includes a heat shield that can cover the fixed end of the housing and the rotating motor.

[0016] In the above technical solution, by setting up a heat insulation cover, the heat insulation cover can reduce the loss of cold air emitted by the ice cubes and cold water in the container, thereby allowing the cold air to be gathered around the rotating motor as much as possible.

[0017] Furthermore, the heat insulation cover includes a housing that can cover the housing and the fixed end of the rotating motor, and a heat insulation element installed on the outer surface of the housing.

[0018] In the above technical solution, the heat insulation component is installed on the outer wall of the cover. When the cover is placed on the fixed end of the rotating motor and the housing, it can play a role in heat insulation.

[0019] Furthermore, a connecting wire is installed on the cover, and the end of the connecting wire facing away from the cover is fixed to the outer wall of the reactor.

[0020] In the above technical solution, the connecting line can reduce the probability of the casing being lost.

[0021] In summary, this application has the following technical effects: when it is necessary to cool the material in the reactor, cold water can be introduced into the cooling coil to cool the material in the reactor; when it is necessary to heat the material in the reactor, steam can be introduced into the heating coil through the side wall of the reactor to heat the material in the reactor; and the heat insulation layer can reduce the heat loss emitted by the heating coil.

The stirring device 5 includes a rotary motor 51 installed on the reaction vessel 1, and a stirring shaft 52 installed on the output end of the rotary motor 51. The axis of the stirring shaft 52 coincides with the axis of the output end of the rotary motor 51. Eight stirring paddles 53 are provided on the stirring shaft 52. Each stirring paddle 53 includes a paddle plate 531 and an arc plate 532 formed at one end of the length direction of the paddle plate 531. The radius of the inner sidewall of the arc plate 532 is the same as the radius of the stirring shaft 52. A connecting plate 533 is formed at both ends of the arc plate 532 in the length direction. During installation, the inner sidewalls of the arc plates 532 on two stirring paddles 53 are attached to the outer sidewall of the stirring shaft 52. The two oppositely arranged connecting plates 533 are connected by bolts and nuts. At this time, the two stirring paddles 53 can be fixed in position relative to the stirring shaft 52 due to friction.

[0030] Reference Figure 2 ,3 This embodiment also includes a cooling coil 2, which extends out of the reactor 1. The cooling coil 2 is spiral-shaped inside the reactor 1 and fits against the inner wall of the reactor 1. A heating coil 3 is installed on the outer wall of the reactor 1. The heating coil 3 is installed on the outer wall of the reactor 1 by clamps. The clamps include an arc-shaped plate and mounting plates corresponding to both ends of the arc-shaped plate along its length. During installation, the inner wall of the arc-shaped plate fits against the outer wall of the heating coil 3, and then the mounting plates are fixed to the outer wall of the reactor 1 with screws. Multiple clamps are provided. The cooling coil 2 can be connected to a tap water pipe that can discharge cold water. The heating coil 3 can be connected to a steam generator. Operators can introduce cold water into the cooling coil 2 to lower the temperature of the material inside the reactor 1, or they can introduce steam into the heating coil 3 to heat the material inside the reactor 1 through the side wall of the reactor 1.

[0031] Reference Figure 1 A heat insulation layer 4 is installed on the outer wall of the reactor 1 using a peelable adhesive. The heat insulation layer 4 can be made of readily available aluminum foil pearl cotton heat insulation film. The heat insulation layer 4 covers the heating coil 3 and is fixed to the outer wall of the reactor 1 by a connector made of peelable adhesive, which can be nano-residue-free double-sided tape. The heat insulation layer 4 can concentrate heat, thereby ensuring the heating effect of the heating coil 3 on the materials inside the reactor 1 and reducing the waste of heat generated by the heating coil 3.

[0032] Reference Figure 4 , 5 A frame-shaped container 6 with an open top is installed on the top of the reactor 1. The container 6 can be arranged around the rotating motor 51, and the side wall of the container 6 can fit against the outer side wall of the rotating motor 51. The container 6 is used to hold substances such as ice cubes and cold water that can cool the rotating motor 51. A drain valve 7 is installed at the bottom of the side wall of the container 6 to facilitate the drainage of water from the container 6. This embodiment also includes a heat insulation cover 8 that can cover the container 6. The heat insulation cover 8 includes a shell 81 that can cover the container 6 and a heat insulation element 82 installed on the outer surface of the shell 81. The heat insulation element 82 can also be made of aluminum foil pearl cotton heat insulation film. The bottom end of the shell 81 can abut against the top of the reactor 1. By setting the heat insulation cover 8, the cold air generated by the ice cubes or cold water placed in the container 6 can be collected around the fixed end of the rotating motor 51. A connecting wire is installed on the cover 81. The end of the connecting wire away from the cover 81 is installed on the outer wall of the reactor 1. By setting the connecting wire, the cover 81 is less likely to be lost.

[0033] The working principle of this embodiment is as follows: When it is necessary to cool the material in the reactor 1, cold water can be introduced into the cooling coil 2 to cool the material in the reactor 1. When it is necessary to heat the material in the reactor 1, steam can be introduced into the heating coil 3 through the side wall of the reactor 1 to heat the material in the reactor 1. The heat insulation layer 4 can reduce the heat loss emitted by the heating coil 3.
