[0032] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0033] like Figure 1-Figure 5 As shown, the utility model proposes an organic compound synthesis reaction device, which mainly includes a frame 1, a reactor 2, a sealed reactor cover 3, a condenser 4, a stirring sleeve rod 5, a fixed shaft 6, a mounting block 7, a first bevel gear 8, a second bevel gear 9, a stirring rod 10 and a second stirring blade 14.

[0034] The reactor 2 is fixedly arranged on the frame 1. The reactor 2 is double-layered. The outer layer is provided with an inlet and an outlet for communicating with the heat medium. The circulating heat medium is input into the outer cavity, thereby providing heating conditions for the material synthesis reaction in the inner cavity of the reactor 2. The top of the inner cavity is provided with an opening, and the bottom of the inner cavity of the reactor 2 is provided with a discharge port. The discharge port is provided with a discharge valve 17. The sealing kettle cover 3 is provided with a locking cover on the opening of the inner cavity of the reactor 2. The sealing kettle cover 3 is connected to a feed hopper 18 connected to the inner cavity of the reactor 2. The condenser 4 is fixedly arranged on the frame 1 and is connected to the inner cavity of the reactor 2 through a reflux elbow. The condenser 4 is provided with a vacuum port for vacuuming.

[0035] The stirring sleeve rod 5 is rotatably arranged in the reactor 2 along the vertical direction. The top of the stirring sleeve rod 5 extends out from the sealed reactor cover 3 and is fixedly connected to the output shaft of the motor 16. The motor 16 is lifted and arranged on the frame 1, which is conducive to adjusting the position of the stirring rod 10 at the bottom of the stirring sleeve rod 5 in the inner cavity of the reactor 2 during installation. The stirring sleeve rod 5 and the sealed reactor cover 3 are mechanically sealed by polytetrafluoroethylene material.

[0036] A plurality of groups of second stirring blades 14 are arranged in a vertical direction on the outer wall of the stirring sleeve rod 5, and the plurality of groups of second stirring blades 14 are all located above the mounting block 7. In the present embodiment, each group of second stirring blades 14 includes two symmetrically arranged ones, and a plurality of screw sleeves 15 are provided on the outer wall of the stirring sleeve rod 5 by threads, and each group of second stirring blades 14 is fixedly connected to the outer wall of a screw sleeve 15. The plurality of groups of second stirring blades 14 are threadedly connected to the stirring sleeve rod 5 by the screw sleeves 15, and the height of the plurality of groups of second stirring blades 14 can be adjusted before installation according to the different liquid level heights to be prepared, so as to ensure that the plurality of groups of second stirring blades 14 rotate below the liquid level, ensure the stirring effect, and avoid the problem that the second stirring blades 14 are idle above the liquid level and do not work. In addition, a baffle rod can be slidably provided on the sealing kettle cover 3 in the vertical direction, and a sealing gasket is provided between the baffle rod and the sealing kettle cover 3. During the synthesis reaction experiment, if the liquid level changes, the baffle rod can be lowered so that the baffle rod is blocked on the side of the second stirring blade 14 whose height needs to be adjusted. When the second stirring blade 14 rotates to abut against the baffle rod, due to the obstruction of the baffle rod, the second stirring blade 14 cannot rotate with the stirring sleeve rod 5, but descends along the stirring sleeve rod 5 through the thread until it descends below the liquid level, and then the bottom of the baffle rod is pulled out, so that the group of second stirring blades 14 can continue to stir, which is highly practical.

[0037] The fixed shaft 6 is passed through the stirring sleeve rod 5, and the upper end is fixedly connected to the sealing kettle cover 3. The mounting block 7 is fixedly set at the bottom of the stirring sleeve rod 5. A mounting cavity is opened inside the mounting block 7. The bottom of the fixed shaft 6 extends into the mounting cavity. The first bevel gear 8 is set in the mounting cavity and fixedly connected to the bottom of the fixed shaft 6. The second bevel gear 9 is rotatably set in the mounting cavity and meshes with the first bevel gear 8. One end of the stirring rod 10 is fixedly connected to the second bevel gear 9, and the other end extends out of the mounting cavity and is rotatably set in the reactor 2. Two groups of first stirring blades 13 are symmetrically arranged on the side wall of each stirring rod 10, and each group of first stirring blades 13 includes a plurality of first stirring blades arranged along the central axis of the stirring rod 10.

[0038] like Figure 2 , Figure 4As shown, in one embodiment, there are two stirring rods 10, which are symmetrically arranged on both sides of the mounting block 7, and the second bevel gears 9 are two with the same size and number of teeth, which are fixedly connected to the two stirring rods 10 respectively, and are meshed with the first bevel gear 8. In this embodiment, the two second bevel gears 9 are meshed with the first bevel gear 8, so that the two stirring rods 10 rotate in the opposite direction, and the speed is the same, thereby ensuring the adequacy of stirring. The specific operation steps are: the motor 16 drives the stirring sleeve rod 5 to rotate, and the stirring sleeve rod 5 drives the mounting block 7 to rotate, thereby driving the multiple groups of second stirring blades 14, the two stirring rods 10 on the mounting block 7 and the first stirring blade 13 to rotate with the central axis of the stirring sleeve rod 5 as the axis. At the same time, since the fixed shaft 6 is fixed, the first bevel gear 8 is fixed, and under the rotation of the mounting block 7 and the meshing state of the second bevel gear 9 and the first bevel gear 8, the two second bevel gears 9 are rotated in the opposite direction, thereby driving the two stirring rods 10 to rotate in the opposite direction, so that the two stirring rods 10 can rotate in the opposite direction under the state of revolution, and the rotation speeds are different.

[0039] like Figure 3 , Figure 5As shown, in another embodiment, there are two stirring rods 10, which are symmetrically arranged on both sides of the mounting block 7, one of the stirring rods 10 is fixedly connected to the second bevel gear 9, and the ends of the two stirring rods 10 extending into the mounting cavity are fixedly provided with a third bevel gear 11, the third bevel gear 11 is coaxially arranged with the second bevel gear 9, and the diameter of the third bevel gear 11 is smaller than the diameter of the second bevel gear 9, the number of teeth of the third bevel gear 11 and the second bevel gear 9 are different, and a fourth bevel gear 12 is rotatably arranged on the second bevel gear 9, there are two fourth bevel gears 12, which are symmetrically arranged in the mounting cavity with the central axis of the second bevel gear 9 as the axis, and each fourth bevel gear 12 is meshed with two third bevel gears 11. The two fourth bevel gears 12 are arranged in this embodiment, which is beneficial to ensure the smooth rotation of the third bevel gear 11 and avoid tilting of the stirring rod 10. In this embodiment, the third bevel gear 11 is meshed with the fourth bevel gear 12 to make the two stirring rods 10 rotate in opposite directions, and by setting the diameter and number of teeth of the third bevel gear 11 and the second bevel gear 9 to be different, the rotation speeds of the two stirring rods 10 are different, thereby further ensuring sufficient stirring. The specific operating steps are as follows: the motor 16 drives the stirring sleeve rod 5 to rotate, and the stirring sleeve rod 5 drives the mounting block 7 to rotate, thereby driving the two stirring rods 10 on the mounting block 7 and the first stirring blade 13 to rotate with the central axis of the stirring sleeve rod 5 as the axis. At the same time, since the fixed shaft 6 is fixed, the first bevel gear 8 is fixed, and under the rotation of the mounting block 7 and the meshing state of the second bevel gear 9 and the first bevel gear 8, the second bevel gear 9 is rotated, thereby driving the stirring rod 10 fixedly connected to the second bevel gear 9 to rotate, and the stirring rod 10 drives the third bevel gear 11 thereon to rotate, and the third bevel gear 11 drives the two fourth bevel gears 12 to rotate, and the two fourth bevel gears 12 drive another third bevel gear 11 to rotate, and the third bevel gear 11 drives the other stirring rod 10 fixed thereto to rotate in the opposite direction, thereby realizing that the two stirring rods 10 rotate in the opposite direction in the state of revolution, and the rotation speeds are different.

[0040] In the above embodiments, the mounting block 7, the first bevel gear 8, the second bevel gear 9, the third bevel gear 11 and the fourth bevel gear are all made of lightweight materials, wherein the mounting block 7 is also made of anti-corrosion material, which is beneficial to reduce the load on the stirring sleeve 5 and the fixed shaft 6 and avoid chemical corrosion.

[0041] The above description is only a preferred embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
