The heat exchange coil 18 is spiral in shape. A steam inlet 19 and a cooling water outlet 20 are respectively opened on the outer surface of the heat-conducting jacket 17. The spiral heat exchange coil 18 increases the contact area with the material in the vessel, greatly improving the heat exchange efficiency, and enabling heating or cooling... The process is more efficient and uniform. Steam can be introduced through steam inlet 19 for heating and cooling water can be discharged through cooling water outlet 20 for cooling. The reaction is stabilized by precise control. The transmission device 15 includes a shaft 21, which is located inside the vessel body 12. A shaft seal 22 is fixedly connected to the upper outer surface of the shaft 21. The purpose is to ensure stable transmission of the shaft 21 inside the vessel body 12. The shaft seal 22 effectively prevents the material inside the vessel from leaking along the shaft 21, ensuring the sealing and safety of the reaction environment and avoiding the danger or impact on the reaction process caused by material leakage.
[0017] The outer surface of the shaft 21 is fixedly sleeved with two worm gear four-blade paddles 25, the upper end of the shaft 21 is fixedly connected with a shaft coupling 23, the upper end of the kettle cover 13 is fixedly installed with a speed reducer motor 24, the output end of the speed reducer motor 24 is fixedly connected with the shaft coupling 23, the speed reducer motor 24 in the transmission device 15 is connected with the shaft 21 through the shaft coupling 23, which can provide power for the shaft 21, so that the shaft 21 drives the worm gear four-blade paddle 25 to rotate, thereby realizing the stirring function of the materials in the kettle, making the materials more uniformly mixed, accelerating the reaction process, and the setting of the heat-conducting jacket 17 and the heat exchange coil 18 provides a basic structural support for the heating and cooling functions of the reaction kettle. The heat-conducting jacket 17 can realize the flow of heating or cooling medium through the steam inlet 19 and the cooling water outlet 20, and the heat exchange coil 18 is spiral-shaped, which can increase the heat exchange area with the materials in the kettle, and together realize the temperature control of the materials in the reaction kettle.
[0018] The discharge device 16 includes a valve body 28, the upper end of the valve body 28 is fixedly installed with a cylinder 31, the output end of the cylinder 31 is fixedly connected with a valve rod 32, the bottom end of the valve rod 32 is fixedly connected with a valve flap 33, the valve flap 33 is conical, and the diameter of the valve flap 33 is the same as the inner diameter of the valve body 28, the valve body 28 is y-shaped, the conical valve flap 33 is adapted to the inner diameter of the valve body 28, and can accurately control the material discharge speed and flow under the control of the cylinder 31, the y-shaped valve body 28 is designed to facilitate smooth material entry and exit, reduce material residue, and facilitate material discharge and subsequent cleaning, one end of the valve body 28 is provided with a feed inlet 29, the other end of the valve body 28 is provided with a discharge port 30, by controlling the stroke of the valve rod 32 pushed or pulled by the cylinder 31, the gap between the valve flap 33 and the sealing surface of the valve body 28 can be accurately controlled, thereby adjusting the flow and speed of the discharge. When fast discharge is required, the valve flap 33 can be opened to a larger degree; when slow discharge or controlled discharge is required, the opening degree of the valve flap 33 is reduced to meet different process requirements.
[0019] Working principle: the operator slowly adds solid materials into the kettle body 12 through the feed hole 26 on the kettle cover 13; for liquid materials, the feed hole 26 can be connected by pipeline, and the liquid materials can be delivered into the kettle by gravity or pressure, the speed reducer motor 24 is started, the motor output shaft rotates, and power is transmitted to the shaft 21 through the shaft coupling 23, the shaft 21 drives the worm gear four-blade paddle 25 fixedly sleeved on its outer surface to rotate. The unique shape and structure of the worm gear four-blade paddle 25 can push the materials in the kettle to form a complex flow pattern and generate a large stirring force when rotating, so as to promote the materials to be fully mixed in the kettle body 12;
[0020] When the reactor needs to be heated, high-temperature steam enters the jacket from the steam inlet 19 on the outer surface of the heat-conducting jacket 17. The heat carried by the steam is transferred to the kettle body 12 through the inner wall of the jacket, thereby increasing the temperature of the material in the kettle. At the same time, the heat exchange coil 18 on the inner surface of the kettle body 12 is also heated by high-temperature medium. The spiral design increases the heat exchange area, so that the heat exchange coil 18 can exchange heat with the material more efficiently, further accelerating the heating speed of the material, and making the temperature of the material rise more uniformly to meet the temperature requirements of the reaction;
[0021] When the reactor needs to be cooled or the temperature is too high and needs to be controlled, cooling water enters the jacket from the corresponding inlet of the heat-conducting jacket 17. The cooling water flows in the jacket, absorbs the heat transferred from the kettle body 12, and then flows out from the cooling water outlet 20, thereby reducing the temperature of the kettle body 12 and the material inside. The heat exchange coil 18 can also be connected to low-temperature cooling medium to further enhance the cooling effect. By controlling the flow, flow rate and time of steam and cooling water, the temperature of the material in the reactor can be accurately adjusted;
[0022] After the reaction is completed, the cylinder 31 in the discharge device 16 is started, the piston rod of the cylinder 31 is extended, the valve rod 32 is pushed downward, the valve disc 33 at the lower end is moved downward, the valve disc 33 is conical and has the same diameter as the inner diameter of the valve body 28. As the valve disc 33 moves, the passage in the valve body 28 is opened, the material in the kettle body 12 flows out from the lower end of the discharge port 10 under the action of gravity, enters the valve body 28 through the feed port 29 on the valve body 28, and then is discharged from the discharge port 30. Since the valve body 28 is designed in a Y shape, this structure is beneficial to the smooth flow of the material and reduces the residual material. By controlling the action of the cylinder 31, the opening of the valve disc 33 can be accurately controlled, thereby accurately controlling the discharge speed and flow of the material to meet the requirements of different production processes for discharging the material.
