It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] Please refer to the following: Figures 1 to 4 The present invention provides a description of a hybrid synthesis experimental reactor. The hybrid synthesis experimental reactor includes a mounting frame 1, a reaction chamber 2, a cover plate 3, a stirring paddle 4, and a spiral temperature control tube 5. The reaction chamber 2 is mounted on the mounting frame 1; the cover plate 3 is mounted on the mounting frame 1 and located above the reaction chamber 2. The position of the cover plate 3 on the mounting frame 1 has a degree of freedom for vertical adjustment, used to cover the reaction chamber 2; the stirring paddle 4 is mounted on the cover plate 3, and the stirring paddle 4 includes a rotating rod 41 rotatably mounted on the cover plate 3, and a stirring blade 42 fixedly mounted at the bottom end of the rotating rod 41; the spiral temperature control tube 5 is fixedly mounted on the cover plate 3 and is wound around the outside of the rotating rod 41.

[0018] The hybrid synthesis experimental reactor provided in this embodiment, compared with the prior art, features a mounting frame 1 for fixed installation on the ground. A reaction chamber 2 is fixedly mounted on the mounting frame 1, and a cover plate 3 is positioned directly above the reaction chamber 2. The cover plate 3 is mounted on the mounting frame 1 and has vertical adjustment freedom in its position, allowing it to cover the opening of the reaction chamber 2. In this application, a rotating rod 41 is rotatably mounted on the cover plate 3, and a stirring blade 42 is fixedly mounted at the bottom of the rotating rod 41. A spiral temperature regulating tube 5 is fitted around the outside of the rotating rod 41, spirally wound around it and spaced apart from the rotating rod 41, and positioned above the stirring blade 4, thus avoiding interference with the rotation of the stirring blade 4. The internal temperature of the reaction chamber 2 can be regulated by supplying a heating or cooling medium into the spiral temperature regulating tube 5. The spiral temperature control tube 5 is fixedly installed on the cover plate 3 and sleeved on the outside of the rotating rod 41 on the stirring paddle 4, making the structure of this application simple and compact. At the same time, opening the cover plate 3 also facilitates the cleaning and maintenance of the spiral temperature control tube 5 in the later stage.

[0019] Specifically, in this embodiment, a lead screw is rotatably mounted on the mounting bracket 1, the lead screw is arranged in the vertical direction, and a threaded sleeve that is threadedly connected to the lead screw is fixedly connected to the cover plate 3. The rotation of the lead screw can synchronously drive the cover plate 3 to move up and down, thereby realizing the adjustment of the position of the cover plate 3.

[0020] Preferably, in this embodiment, when the cover plate 3 is installed over the opening of the reaction chamber 2, the cover plate 3 and the reaction chamber 2 are sealed together.

[0021] In some embodiments, the cover plate 3 may be adopted as follows: Figure 1 , Figure 3 The structure shown. See also... Figure 1 , Figure 3 The outer ring of the cover plate 3 is fixedly equipped with a first feed pipe 31 for connecting to one end of the spiral temperature-regulating pipe 5, and a first discharge pipe 32 for connecting to the other end of the spiral temperature-regulating pipe 5. A first regulating valve 311 for adjusting the flow rate is installed on the first feed pipe 31. The first feed pipe 31 and the first discharge pipe 32 are fixedly installed on the outer surface of the cover plate 3, respectively connected to both ends of the spiral temperature-regulating pipe 5. When it is necessary to raise the temperature inside the reaction chamber 2, the input end of the heating medium can be connected to the first feed pipe 31, and the output end of the heating medium can be connected to the first discharge pipe 32. The temperature inside the reaction chamber 2 is increased by the flow of the heating medium inside the spiral temperature-regulating pipe 5. Conversely, when the mixing and synthesis reaction requires cooling inside the reaction chamber 2, the cooling medium can be connected to the spiral temperature-regulating pipe 5 through the first feed pipe 31 and the first discharge pipe 32 to cool the inside of the reaction chamber 2.

[0022] Specifically, in this embodiment, a first regulating valve 311 is provided on the first feed pipe 31, and a temperature sensor for monitoring the internal temperature of the reaction chamber 2 is provided on the reaction chamber 2 or the cover plate 3. Therefore, the opening degree of the first regulating valve 311 can be adjusted by the change in the internal temperature of the reaction chamber 2 to stabilize the internal temperature of the reaction chamber 2, thereby obtaining effective experimental data.

[0023] Specifically, the heating medium can be steam or a liquid with a heat source; the cooling medium is a cryogenic liquid, which can be connected to a condenser for cryogenic liquid circulation.

[0024] In some embodiments, the reaction chamber 2 described above can be as follows: Figure 2 , Figure 4 The structure shown. See also... Figure 2 , Figure 4 An inner liner 21 is fixedly installed on the reaction chamber 2. When the cover plate 3 is placed on the reaction chamber 2, it is sealed to the opening of the inner liner 21. The inner liner 21 can be made of a relatively stable and corrosion-resistant material, such as stainless steel. By designing the inner liner 21 as a higher-priced corrosion-resistant material, costs can be saved. At the same time, the stability of monitoring data and subsequent test data can be improved.

[0025] Specifically, in this embodiment, a drain pipe is connected to the bottom of the inner liner 21, and a control valve for controlling the flow state is installed on the drain pipe.

[0026] In some embodiments, the inner liner 21 may be adopted as follows: Figure 4 The structure shown. See also Figure 4 The reaction chamber 2 has a mounting cavity for installing the inner liner 21. When the inner liner 21 is installed inside the mounting cavity, it is spaced apart from the inner wall of the mounting cavity. The top of the inner liner 21 is installed on the top of the mounting cavity and fixedly mounted on the reaction chamber 2. The reaction chamber 2 has a mounting cavity with an inner diameter larger than the outer diameter of the inner liner 21. Therefore, when the inner liner 21 is installed on the reaction chamber 2, it is spaced apart from the inner wall of the mounting cavity. This reduces heat conduction between the inner liner 21 and the outside environment, ensuring a stable mixing reaction environment inside the inner liner 21.

[0027] Specifically, in this embodiment, a support flange is provided at the opening of the inner liner 21, which is bent outward. The support flange overlaps the opening of the mounting cavity and is fixedly installed on the reaction chamber 2 by welding.

[0028] In some embodiments, the inner liner 21 may be adopted as follows: Figure 4 The structure shown. See also Figure 4The opening of the inner liner 21 protrudes from the top surface of the reaction chamber 2, and a boss 35 protrudes from the cover plate 3 for sliding into the inner liner 21. The opening of the inner liner 21 protrudes from the top surface of the reaction chamber 2, and the opening of the inner liner 21 has a rounded chamfered structure. A boss 35 protrudes from the lower side of the cover plate 3 and slides into the opening of the inner liner 21. The end of the boss 35 away from the cover plate 3 has a rounded chamfer, which facilitates the sliding of the boss 35 into the opening of the inner liner 21.

[0029] Preferably, in this embodiment, the boss 35 has a conical structure, and the outer diameter of the boss 35 gradually increases along the direction close to the cover plate 3, so as to achieve a sealed connection between the boss 35 and the inner liner 21 by pressing the cover plate 3 tightly onto the reaction chamber 2.

[0030] Alternatively, in another embodiment, a sealing ring is installed on the cover plate 3. The sealing ring is fitted on the outside of the boss 35, and when the cover plate 3 is installed on the reaction chamber 2, the inner liner 21 is fixed against the sealing ring to achieve a seal between the boss 35 and the cover plate 3.

[0031] Specifically, in this embodiment, a pressure gauge for monitoring the internal pressure of the inner liner 21 is also installed on the cover plate 3.

[0032] In some embodiments, the reaction chamber 2 described above can be as follows: Figure 1 , Figure 2 The structure shown. See also... Figure 1 , Figure 2 Multiple screws 6 are fixedly installed on the reaction chamber 2. Corresponding through holes are provided on the cover plate 3 for installing the screws 6. Tightening components 61 are threaded onto the screws 6 to press the cover plate 3 onto the reaction chamber 2. Multiple screws 6 are fixedly installed on the top of the reaction chamber 2, with their length direction vertical and evenly spaced along the circumference of the reaction chamber 2. Through holes corresponding to the screws 6 are provided on the cover plate 3. When the cover plate 3 moves downwards, the screws 6 pass through the through holes. The tightening components 61 are bolts, which further secure the cover plate 3 onto the reaction chamber 2, improving the stability of the cover plate 3 on the reaction chamber 2.

[0033] In some embodiments, the mounting bracket 1 described above may be as follows: Figure 1 The structure shown. See also Figure 1A connecting arm 7 for mounting the cover plate 3 is slidably mounted on the mounting frame 1. A driving component 8 for driving the rotating rod 41 to rotate is mounted on the connecting arm 7. The mounting frame 1 includes a base and a column fixedly mounted on the base. The column is vertically oriented, and one side of the reaction chamber 2 is fixedly mounted on the column. The connecting arm 7 is slidably mounted on the column vertically. The cover plate 3 moves up and down by moving the connecting arm 7. Simultaneously, the connecting arm 7 is rotatably mounted on the mounting frame 1 along the axis of the column. After opening the cover plate 3, it can be rotated to one side, facilitating cleaning and maintenance of the interior of the reaction chamber 2 and the components on the cover plate 3.

[0034] Preferably, in this embodiment, a movable tube that is slidably mounted on the column is fixedly installed on the connecting arm 7, and the movable tube is fitted onto the outside of the column. A threaded sleeve is fixedly installed on the movable tube. A lead screw that is threadedly connected to the threaded sleeve is rotatably mounted on the column. By rotating the lead screw, the vertical position of the movable tube can be adjusted, thereby adjusting the vertical position of the cover plate 3.

[0035] Specifically, in this embodiment, the driving component 8 is a motor, and a fixing plate for mounting the driving component 8 is fixedly installed on one side of the connecting arm 7. The driving component 8 is fixedly mounted on the fixing plate with bolts, so that when the connecting arm 7 moves with the cover plate 3, it can move the driving component 8 synchronously.

[0036] In some embodiments, the cover plate 3 may be adopted as follows: Figure 1 , Figure 3 The structure shown. See also... Figure 1 , Figure 3 A sleeve 411 is fixedly installed on the top of the cover plate 3. A rotating rod 41 is rotatably disposed inside the sleeve 411 and is sealed to the sleeve 411. A connecting sleeve 412 is rotatably disposed on the outside of the sleeve 411 and is fixedly connected to the rotating rod 41. The sealing structure between the rotating rod 41 and the sleeve 411 is the same as the sealing structure of the stirring shaft on a conventional reactor, which is existing technology and will not be described further here. A connecting sleeve 412 is fixedly installed on the top of the rotating rod 41 and is rotatably disposed on the outside of the sleeve 411 via a bearing. A first pulley is fixedly installed on the outside of the connecting sleeve 412, and a second pulley is fixedly installed on the driving end of the driving component 8, so that the driving component 8 can drive the connecting sleeve 412 to rotate via a belt.

[0037] Specifically, in this embodiment, the driving component 8 drives the connecting sleeve 412 to rotate outside the sleeve 411. The connecting sleeve 412 is fixedly connected to the rotating rod 41 and is coaxially arranged with the rotating rod 41. This allows the connecting sleeve 412 to synchronously drive the rotating rod 41 to rotate when it rotates, thereby achieving a stirring effect.

[0038] In some embodiments, the cover plate 3 may be adopted as follows:Figure 3 The structure shown. See also Figure 3 The cover plate 3 is also equipped with a second feed pipe 33 and a second discharge pipe 34, and a U-shaped pipe 9 connects the second feed pipe 33 and the second discharge pipe 34. The U-shaped pipe 9 is located on one side of the spiral temperature regulating pipe 5, and a second regulating valve 331 for adjusting the flow rate is installed on the second feed pipe 33. A U-shaped pipe 9 is also installed at the bottom of the cover plate 3. The U-shaped pipe 9 can cooperate with the spiral temperature regulating pipe 5 to regulate the temperature inside the reaction chamber 2 and further stabilize the temperature inside the reaction chamber 2.

[0039] Preferably, in this embodiment, during practical application, a heating medium can be supplied to the spiral temperature control tube 5, and a cooling medium can be supplied to the U-shaped tube 9. The temperature inside the reaction chamber 2 can be adjusted by controlling the flow rate inside the spiral temperature control tube 5 and the U-shaped tube 9, thereby achieving temperature regulation and improving the applicability of the reaction vessel.
