Description

Technical Field

[0001] The utility model relates to a temperature control structure for polyester polyol synthesis and processing, belonging to the technical field of polyester polyol. Background Art

[0002] Temperature control devices are required during the synthesis of polyester polyols. Temperature control devices are an indispensable part of modern industrial automation. Their main function is to monitor and regulate the temperature in various equipment and systems to ensure the stability of the production process and the quality of the product. Temperature control devices are widely used in manufacturing, food processing, healthcare, chemical industry and other industries, playing a vital role in these fields.

[0003] A Chinese patent publication (publication number: CN 216260769 U) discloses a polyester polyol production device with a multi-stage heating control system, which belongs to the technical field of polyester polyol production. The key points of its technical solution include a kettle body, an upper end surface of the kettle body is equipped with a motor, an output end of the motor is fixedly connected to a rotating shaft, and three heating chambers are fixedly connected to the outer wall of the kettle body and are distributed up and down, thereby forming three heating areas, heating the upper middle and bottom parts of the kettle body respectively. The electric heating blocks inside the three heating chambers can be independently controlled by the control box, thereby realizing multi-stage independent control and flexible control of the temperature of the upper, middle and lower parts of the kettle body, effectively preventing the powder and other raw materials entering from the upper part to the temporal part of the kettle body from being heated in advance, thereby affecting the quality of the produced products. The invention solves the problem that the heating structure of the existing polyester polyol reactor is simple and cannot realize multi-stage independent heating control, resulting in the powder and other raw materials entering from the upper part to the kettle being heated in advance, thereby affecting the quality of the produced products.

[0004] The above-mentioned device needs to be equipped with multiple temperature sensors, and the positions of the temperature sensors are relatively fixed, which increases the overall cost of the equipment. Since the position of the temperature sensor cannot be adjusted, it may be impossible to detect the temperature at multiple heights in the kettle, resulting in low temperature detection efficiency. At the same time, the above-mentioned device is only equipped with a heating device. When the temperature inside the kettle is too high, it cannot be cooled down in time, resulting in poor overall temperature control effect of the equipment.

[0005] Therefore, a temperature control structure for polyester polyol synthesis processing is proposed. Utility Model Content

[0028] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0031] The surface of the kettle body 1 is provided with a temperature control mechanism 2, which includes a heating chamber 201 and an L-shaped rod 209. The two heating chambers 201 are both opened on the upper and lower sides of the inner surface of the kettle body 1. The inner cavities of the two heating chambers 201 are fixedly installed with electric heating wires 202. The middle end of the inner surface of the kettle body 1 is provided with a cooling chamber 203. The left and right sides of the inner cavity of the cooling chamber 203 are connected with cooling water pipes 204. The two cooling water pipes 204 are connected to the external cooling water supply device. The L-shaped rod 209 is located at the top of the cover plate 4. The bottom of the L-shaped rod 209 is fixedly installed with a temperature sensor 210. The cover plate 4 is provided with a temperature sensor 210. A mounting plate 205 is fixedly installed on the top, a servo motor 206 is fixedly installed on the top of the cover plate 4, the output end of the servo motor 206 is fixedly connected to a screw rod 207, the surface of the screw rod 207 is threadedly connected to a screw block 208, the other end of the L-shaped rod 209 is fixedly installed on the front side of the screw block 208, a temperature control panel 211 is fixedly installed on the surface of the kettle body 1, the output end of the temperature sensor 210 is electrically connected to the input end of the temperature control panel 211, a limit frame 212 is fixedly installed on the top of the mounting plate 205, and the inner surface of the screw block 208 is slidably connected to the surface of the limit frame 212.

[0032] By setting up the temperature control mechanism 2, the temperature in the inner cavity of the kettle body 1 can be conveniently regulated through the heating of the electric heating wire 202 and the cooling water injected by the cooling water pipe 204, thereby improving the convenience of temperature control in the inner cavity of the kettle body 1. When it is necessary to detect the temperature at different levels in the inner cavity of the kettle body 1, the output of the servo motor 206 drives the screw block 208 to move up and down. At this time, the L-shaped rod 209 synchronously drives the temperature sensor 210 to move up and down, so that the temperature sensor 210 can detect the temperature of different areas of the kettle body 1. The invention saves the need to equip multiple temperature sensors 210 when detecting the temperature at different levels of the kettle body 1, reduces the cost of the equipment, and expands the detection range of the temperature sensor 210. By setting the temperature control panel 211, it is convenient to receive the temperature value transmitted by the temperature sensor 210, and it is convenient to timely control the operation or stop of the electric heating wire 202.

[0033] Example 2

[0034] like Figure 1 、 Figure 3 、 Figure 4 and Figure 5As shown, in one embodiment, a stirring mechanism 3 is provided on the top of the cover plate 4, and the stirring mechanism 3 includes a rotating motor 301 and a conical gear ring 303. The rotating motor 301 is located at the top of the cover plate 4, and the conical gear ring 303 is movably connected to the middle end of the top of the cover plate 4. A stirring frame 304 is fixedly installed at the bottom of the conical gear ring 303. The L-shaped rod 209 passes through the inner sides of the conical gear ring 303 and the stirring frame 304 and extends into the inner cavity of the kettle body 1. The rotating motor 301 is fixedly installed on the surface of the cover plate 4, and the output end of the rotating motor 301 is fixedly connected to the active bevel gear 302.

[0036] When the present invention is working: the temperature in the inner cavity of the kettle body 1 is increased by the operation of the electric heating wire 202, and then the output of the rotating motor 301 causes the active bevel gear 302 to drive the bevel gear ring 303 and the stirring frame 304 to start stirring the material in the inner cavity of the kettle body 1. At this time, the output of the servo motor 206 causes the screw rod 207 to rotate back and forth, and drives the screw block 208 to move back and forth up and down. At this time, the L-shaped rod 209 synchronously drives the temperature sensor 210 to move back and forth up and down, and performs stable detection of materials at different levels in the inner cavity of the kettle body 1. When it is found that the temperature in the inner cavity of the kettle body 1 is too high, the electric heating wire 202 stops running, and external cooling water is injected into the inner cavity of the cooling chamber 203 through the cooling water pipe 204 to complete the cooling of the inner cavity of the kettle body 1, thereby completing the overall control of the temperature in the inner cavity of the kettle body 1.
