Detailed implementation mode

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific implementation mode.

[0022] As Figures 1-4 shown, a temperature control device for chemical reagents includes a control bottom box 1. A heating component 2 is installed at the bottom of the control bottom box 1. The heating component 2 includes a kettle body 4 and a water tank 9. The water tank 9 is installed at the bottom of the control bottom box 1, and the kettle body 4 is installed on the top of the control bottom box 1. An electric heating tube 5 and a cooling tube 8 are installed around the outside of the kettle body 4. A temperature sensor 6 is installed inside the kettle body 4. A circulation pump 10 is installed through the outside of the water tank 9. An inlet pipe 11 is connected and installed between the top end of the cooling tube 8 and the circulation pump 10, and an outlet pipe 12 is connected and installed between the bottom end of the cooling tube 8 and the water tank 9. Two external connecting pipes 13 are installed through the outside of the water tank 9.

[0023] In this embodiment, both the electric heating tube 5 and the cooling tube 8 are arranged in a spiral shape. The electric heating tube 5 and the cooling tube 8 are installed around the outside of the kettle body 4 in an intersecting and winding manner. The electric heating tube 5 is used to heat the kettle body 4, and the kettle body 4 is quickly cooled to a specified temperature through the cooling tube 8.

[0024] In this embodiment, both ends of the temperature sensor 6 and the electric heating tube 5 are connected to the control bottom box 1 through wires 7. Both ends of the cooling tube 8 communicate with each other from the inlet pipe 11 to the outlet pipe 12. The control bottom box 1 is connected to the electric heating tube 5 and the temperature sensor 6 through wires 7 to control heating and monitor the temperature of the reagent inside the kettle body 4.

[0025] In this embodiment, the two external connecting pipes 13 are respectively used for water injection and drainage. The inlet pipe 11 communicates with the water tank 9 through the circulation pump 10. When the temperature inside the kettle body 4 is relatively high or the temperature needs to be lowered, the water in the water tank 9 is transported to the cooling tube 8 through the control of the circulation pump 10 to quickly cool down the kettle body 4.

[0026] In this embodiment, a thermal insulation component 3 is installed outside the kettle body 4. The thermal insulation component 3 includes a protective sleeve 14. The protective sleeve 14 is located outside the kettle body 4 and is fixedly installed on the top of the control bottom box 1. An insulating board 15 is installed between the protective sleeve 14 and the kettle body 4. A vacuum cavity 16 is arranged between the insulating board 15 and the protective sleeve 14. A plurality of support blocks 17 are fixedly installed inside the vacuum cavity 16 and between the insulating board 15 and the protective sleeve 14. A motor 18 is installed on the top of the kettle body 4. The bottom end of the output shaft of the motor 18 is installed with a stirring rod 19. The kettle body 4 is thermally insulated and heat-insulated through the insulating board 15 and the vacuum cavity 16. The stirring rod 19 rotates to prevent the reagent from precipitating and can be heated evenly.

[0027] In this embodiment, the insulating board 15 is arranged in a cylindrical shape outside the kettle body 4. The inner diameter of the inner circle of the insulating board 15 is larger than the outer diameters of the electric heating tube 5 and the cooling tube 8. The insulating board 15 insulates the interior to reduce heat dissipation.

[0028] In this embodiment, a plurality of support blocks 17 are arranged around inside the vacuum cavity 16. The protective sleeve 14 and the insulating board 15 are fixed to each other through the support blocks 17. Heat transfer is reduced through the vacuum cavity 16 to further improve the thermal insulation of the kettle body 4.

[0029] It should be noted that the present utility model is a temperature control device for chemical reagents. When in use, chemical reagents are added into the kettle body 4. When storing or reacting at a specified temperature, the electric heating tube 5 is controlled by the control panel of the control bottom box 1 to heat the kettle body 4. When the temperature sensor 6 monitors that the reagent in the kettle body 4 is heated to the specified temperature, the heating stops. When the temperature inside the kettle body 4 is relatively high or the temperature is lowered, the circulating pump 10 is started to transport the water in the water tank 9 into the cooling tube 8 to quickly cool the kettle body 4, and it is monitored and controlled by the temperature sensor 6 to realize the rapid heating and cooling of the kettle body 4. When performing long-term heat preservation, the insulating board 15 isolates the internal temperature, and the heat dissipation is further reduced through the vacuum cavity 16. The stirring rod 19 is driven by the motor 18 to rotate, so that the reagent is heated evenly and precipitation is prevented.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
