Description

Technical Field

[0001] This utility model relates to the technical field of reactor heating devices, and in particular to a far-infrared electric heating device for reactors. Background Technology

[0002] Far-infrared electric heating devices for reaction vessels are important devices in chemical, pharmaceutical, food processing, and biochemistry industries. They are used to heat materials inside the reaction vessel through far-infrared radiation, thereby improving reaction efficiency and controlling the reaction process. They are mainly composed of far-infrared heating tubes, electrical control systems, heating covers, and insulation layers. The principle is to directly heat the materials inside the reaction vessel through far-infrared radiation heating, thereby improving reaction efficiency and avoiding heat conduction losses that may occur with traditional heating methods.

[0003] Publication number CN222721613U discloses a far-infrared electric heating device for a reaction vessel, including a reaction vessel body and a far-infrared electric heating device disposed at the bottom of the reaction vessel body. The far-infrared electric heating device includes a heating device shell, and a cavity is provided between the heating device shell and the reaction vessel body. An insulation layer and an electric heating element are sequentially provided on the inner wall of the heating device shell within the cavity. A junction box is provided on one side of the heating device shell, and an air filling port and an air exhaust port connected to the cavity are respectively provided on the other side of the heating device shell.

[0004] Although this device uses a positive pressure filling structure to fill the cavity with inert gas, thus preventing the electric heating element from oxidizing and deteriorating, and filling the entire cavity with inert gas to squeeze out other gaseous media and improve safety, far-infrared heating mainly relies on radiation heat sources to heat the surface of materials. The materials inside the reactor may not be heated evenly, resulting in some parts being too hot while others remain too cold, affecting the uniformity and efficiency of the reaction. For some reactants that require uniform mixing, lack of stirring may lead to insufficient contact between reactants, slowing down the reaction rate, or even causing incomplete reaction. In some high-viscosity materials or reaction systems containing solid particles, the materials may precipitate or separate, affecting the reaction process. At the same time, during the heating process, the upper part of the reactor is in direct contact with the external environment, which may cause heat to be lost to the external environment, resulting in low energy efficiency. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a far-infrared electric heating device for a reaction vessel.

[0006] This utility model is achieved using the following technical solution: a far-infrared electric heating device for a reaction vessel, comprising a support frame, a heating mechanism provided on the inner wall of the support frame, a thermometer provided on the inner wall of the heating mechanism, a control box fixedly connected to the top of the support frame, a lower flange fixedly connected to the surface of the heating mechanism, an upper flange bolted to the top of the lower flange, a feed cover provided on the top of the heating mechanism, and a stirring mechanism provided on the inner wall of the heating mechanism;

[0007] The heating mechanism includes a heat insulation cover, an air inlet pipe fixedly connected to the inner wall of the heat insulation cover, an air outlet pipe fixedly connected to the inner wall of the heat insulation cover, a hollow heating wall fixedly connected to the inner wall of the heat insulation cover, an electric heating device fixedly connected to the inner wall of the hollow heating wall, a reaction vessel fixedly connected to the inner wall of the upper flange, and a heat insulation layer fixedly connected to the surface of the reaction vessel.

[0008] As a further improvement to the above solution, the top of the insulation cover is fixedly connected to the bottom of the lower flange, the top of the hollow heating wall is fixedly connected to the surface of the lower flange, and the surface of the insulation cover is fixedly connected to the surface of the control box.

[0009] As a further improvement to the above solution, the surface of the air inlet pipe is fixedly connected to the inner wall of the hollow heating wall, and the surface of the air outlet pipe is fixedly connected to the inner wall of the hollow heating wall.

[0010] As a further improvement to the above solution, the top of the hollow heating wall is fixedly connected to the bottom of the reactor, the bottom of the heat insulation layer is fixedly connected to the top of the upper flange, and the top of the reactor is hinged with a feed cover.

[0011] Through the above technical solution, an insulating layer is fixedly connected to the surface of the reactor. Inert gas is injected into the hollow heating wall through the gas inlet pipe. The electric heating device is activated to heat the material inside the hollow heating wall. The heat insulation cover keeps the hollow heating wall warm. At the same time, the insulating layer insulates the reactor, preventing uneven heating of the internal material due to the cold upper part and hot lower part of the internal space, which could lead to incomplete reaction or the formation of unstable products. This ensures that the material temperature is consistent, guarantees the material reaction efficiency, and improves the practicality of the device.

[0012] As a further improvement to the above solution, the stirring mechanism includes a mounting base, a motor rotatably connected to the inner wall of the mounting base, a rotating shaft at the output end of the motor, and a rudder-shaped fan blade fixedly connected to the bottom of the rotating shaft.

[0013] As a further improvement to the above solution, the surface of the mounting base is fixedly connected to the inner wall of the reactor, and the surface of the mounting base is fixedly connected to the inner wall of the heat insulation layer.

[0014] As a further improvement to the above solution, the top of the mounting base is fixedly connected to the bottom of the motor, and the surface of the rudder-shaped fan blade is rotatably connected to the inner wall of the hollow heating wall.

[0015] The above technical solution involves starting a motor fixedly connected to the top of the mounting base, which drives the rotating shaft to rotate. This causes the rudder-shaped fan blades to rotate on the inner wall of the hollow heating wall, stirring the materials inside the hollow heating wall. This ensures uniform heating and mixing of the reactants, optimizes the reaction process, and improves reaction efficiency. At the same time, it prevents high-viscosity materials or materials with a lot of suspended solids from settling or stratifying, which would affect the uniformity of the reaction and ensure the continuity of the reaction. This helps the materials quickly reach a uniform thermal equilibrium, thereby achieving efficient energy utilization and improving the practicality of the device.

The heat insulation cover keeps the hollow heating wall warm, while the heat insulation layer insulates the reactor, preventing uneven heating of the internal material due to a colder upper part and a hotter lower part, which could lead to incomplete reaction or the formation of unstable products. This ensures a consistent material temperature, guarantees material reaction efficiency, and improves the practicality of the device.

[0018] This invention incorporates a stirring mechanism, specifically a motor fixedly connected to the top of the mounting base. This motor drives a rotating shaft, which in turn rotates a rudder-shaped fan blade within a hollow heating wall. This stirs the materials inside the hollow heating wall, ensuring uniform heating and mixing of the reactants, optimizing the reaction process, and improving reaction efficiency. Simultaneously, it prevents high-viscosity materials or materials with a high amount of suspended solids from settling or stratifying, which could affect reaction uniformity and ensure the continuity of the reaction. This helps the materials quickly reach a uniform thermal equilibrium, thereby achieving efficient energy utilization and improving the practicality of the device. Attached Figure Description

[0029] The heating mechanism 2 includes a heat insulation cover 201, an air inlet pipe 202 fixedly connected to the inner wall of the heat insulation cover 201, an air outlet pipe 203 fixedly connected to the inner wall of the heat insulation cover 201, a hollow heating wall 204 fixedly connected to the inner wall of the heat insulation cover 201, an electric heating device 205 fixedly connected to the inner wall of the hollow heating wall 204, a reaction vessel 206 fixedly connected to the inner wall of the upper flange 6, and a heat insulation layer 207 fixedly connected to the surface of the reaction vessel 206.

[0030] The top of the insulation cover 201 is fixedly connected to the bottom of the lower flange 5, the top of the hollow heating wall 204 is fixedly connected to the surface of the lower flange 5, and the surface of the insulation cover 201 is fixedly connected to the surface of the control box 4.

[0031] The surface of the inlet pipe 202 is fixedly connected to the inner wall of the hollow heating wall 204, and the surface of the outlet pipe 203 is fixedly connected to the inner wall of the hollow heating wall 204. Inert gas is injected into the hollow heating wall 204 through the inlet pipe 202 via the heat insulation layer 207 fixedly connected to the surface of the reactor 206. The electric heating device 205 is activated to heat the material inside the hollow heating wall 204. The heat insulation cover 201 keeps the hollow heating wall 204 warm, while the heat insulation layer 207 insulates the reactor 206 to prevent uneven heating of the material inside due to the cold upper part and hot lower part of the internal space, which could lead to incomplete reaction or the formation of unstable products. This ensures a uniform material temperature, guarantees material reaction efficiency, and improves the practicality of the device.

The surface of the rudder-shaped fan blade 804 is rotatably connected to the inner wall of the hollow heating wall 204. The motor 802, fixedly connected to the top of the mounting base 801, is started, driving the rotating shaft 803 to rotate, which in turn drives the rudder-shaped fan blade 804 to rotate on the inner wall of the hollow heating wall 204.

Then, the feed cover 7 is opened, and raw materials are added into the reactor 206. Inert gas is injected into the hollow heating wall 204 through the air inlet pipe 202. The electric heating device 205 is activated to heat the material inside the hollow heating wall 204. The insulation cover 201 insulates the hollow heating wall 204, while the insulation layer 207 insulates the reactor 206, preventing uneven heating of the internal material due to a colder upper part and a hotter lower part, which could lead to incomplete reaction or the formation of unstable products. This ensures a uniform material temperature, guarantees material reaction efficiency, and improves the practicality of the device. Simultaneously, a motor is fixedly connected to the top of the mounting base 801. Start-up 802 drives the rotating shaft 803 to rotate, which in turn drives the rudder-shaped fan blades 804 to rotate on the inner wall of the hollow heating wall 204, stirring the materials inside the hollow heating wall 204 to ensure uniform heating and mixing of the reactants, optimize the reaction process, improve reaction efficiency, and prevent high-viscosity materials or materials with a lot of suspended solids from settling or stratifying, which would affect the uniformity of the reaction and ensure the continuity of the reaction. This helps the materials quickly reach a uniform thermal equilibrium, thereby achieving efficient energy utilization and improving the practicality of the device. After the reaction is completed, the electric heating device 205 is turned off, and room temperature inert gas is injected through the inlet pipe 202 and discharged through the outlet pipe 203 to accelerate the cooling of the device. At the same time, the feed cover 7 is opened to dissipate heat. Then, the lower flange 5 and the upper flange 6 are separated, and the reactor 206 is removed to clear the materials.
