DETAILED DESCRIPTION

[0018] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0019] Embodiment: A chemical engineering reactor, such as Figure 1-Figure 4 As shown, it includes a kettle body 1, a shell 2, a feed valve 3, an observation window 4, a mounting frame 5, a stirring assembly, a heat-conducting cylinder 8, a semiconductor temperature controller 9 and a discharge valve 10. The shell 2 is arranged around the outside of the kettle body 1. The kettle body 1 is used as the main chemical reaction container, and its outer layer is wrapped by the shell 2, which not only helps to keep warm by isolating the environment, but also effectively prevents the influence of the external environment on the reaction process. A feed valve 3 for controlling the feed of raw materials is arranged on the top of the kettle body 1, which is used to accurately control the raw materials entering the kettle body 1 and plays a switch role, thereby ensuring the stability of the reaction conditions. An observation window 4 that passes through the shell 2 is arranged on the kettle body 1, allowing the operator to directly Then observe the reaction situation in the kettle and adjust the reaction conditions in time. A mounting frame 5 is provided on the top of the kettle body 1, and a stirring assembly is installed on the mounting frame 5. The lower end of the stirring assembly passes through the kettle body 1 and is placed inside to stir and mix the reaction substances. In order to promote the full mixing of the reactants, heat-conducting cylinders 8 are also arranged at intervals on the kettle body 1. The heating end of the heat-conducting cylinder 8 is placed inside the kettle body 1. A semiconductor temperature controller 9 for regulating the temperature is provided inside the heat-conducting cylinder 8. The semiconductor temperature controller 9 can accurately adjust and maintain the temperature required for the reaction to ensure the smooth progress of the reaction. A discharge valve 10 for controlling the discharge of the reactants is provided at the bottom of the kettle body 1.

[0020] Specifically, through the uniform mixing of the stirring component and the uniform heating of the semiconductor temperature controller 9, the reaction conditions of the raw materials placed in the kettle body 1 can be more stable and sufficient, and the semiconductor temperature controller 9 can not only heat but also cool the reactants to meet the different needs of the reactants. It can not only achieve fine adjustment of the temperature, making it suitable for applications with high-precision temperature control, but also can quickly respond to temperature changes and achieve instant temperature adjustment, which provides more selection conditions for the temperature requirements of the reactants, thereby ensuring its good and stable chemical reaction operation.

[0021] like Figure 1 and Figure 3As shown, the stirring assembly includes a first motor 6 and a stirring frame 7. The first motor 6 is arranged on the top of the mounting frame 5. The stirring frame 7 is connected to the output end of the first motor 6. The stirring frame 7 is composed of an arranged rod-shaped body. The bottom end of the stirring frame 7 passes through the kettle body 1 and the two form a rotational fit. The stirring frame 7 is driven to rotate by the first motor 6. Combined with the design of the stirring frame 7, the stirring range can be effectively expanded to promote sufficient mixing of the reactants.

[0022] like Figure 1 and Figure 2 As shown, it also includes a mounting bracket 11 and a connecting shaft 12. The mounting bracket 11 is provided with a connecting shaft 12 rotatably arranged on the left and right sides of the mounting bracket 11, and the ends of the two connecting shafts 12 are respectively connected to the adjacent side of the housing 2.

[0023] like Figure 1 As shown, a second motor 13 is also included. The second motor 13 whose output end is connected to the adjacent connecting shaft 12 is installed on one side of the mounting bracket 11. Driven by the second motor 13, the kettle body 1 carrying the reactants can swing and operate, thereby assisting the chemical reaction of the reactants.

[0024] like Figure 1 As shown, it also includes a discharge hose 14, a high-pressure air pump 15 and a connecting pipe 16. The discharge valve 10 is connected to the discharge hose 14, and the high-pressure air pump 15 is also installed on the mounting bracket 11. The connecting pipe 16 is connected between the air outlet of the high-pressure air pump 15 and the discharge hose 14. The high-pressure gas generated by the high-pressure air pump 15 acts on the discharge hose 14 through the connecting pipe 16, and according to the Bernoulli principle, it helps to push the reaction product to be discharged quickly and smoothly from the kettle body 1, thereby improving the discharge efficiency.

[0025] When using the device, first ensure that the mounting bracket 11 is firmly placed on a flat ground, then add the raw materials into the kettle body 1 through the feed valve 3, then turn on the first motor 6 and the semiconductor temperature controller 9, the first motor 6 drives the connected stirring frame 7 to rotate, so as to fully mix the raw materials in the kettle body 1. Since the stirring frame 7 adopts an arranged rod-shaped structure design, this can significantly increase the contact area between the stirring frame 7 and the raw materials, thereby achieving a more uniform mixing effect. At the same time, the semiconductor temperature controller 9 starts to work, and evenly supplies heat to the kettle body 1 through the heat-conducting tube 8. Since the heat-conducting tube 8 is evenly distributed on the kettle body 1, and its heating end penetrates deep into the kettle body 1, accurate temperature control can be achieved, which not only provides uniform heat distribution, but also can quickly adjust the temperature according to the reaction requirements to ensure the stability of the reaction conditions; in order to facilitate the monitoring of the reaction situation in the kettle body 1, the staff can directly view the internal state through the observation window 4, and then start the second motor 13, the second motor 13 drives the connecting shaft 12 connected to it to swing, and then drives the kettle body 1 loaded with raw materials to swing, so as to further improve the uniformity of raw material mixing. When the material reaction is completed, the discharge valve 10 is opened, and the material will be discharged through the discharge hose 14. In this step, the high-pressure air pump 15 is started to deliver high-pressure gas into the hose through the connecting pipe 16. According to the Bernoulli principle, the material in the discharge hose 14 is discharged smoothly and quickly, ensuring the efficiency and smoothness of the entire discharge process. At this point, the entire reaction process is completed.

[0026] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
