[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0025] See also Figure 1-5 , the utility model provides a technical solution:

[0026] A methyl ethyl carbonate synthesis reactor comprises a reactor body 1, wherein a mixing mechanism is arranged inside the reactor body 1, and the mixing mechanism is divided into a tumbling component and a stirring component;

[0027] The stirring assembly includes a guide rod 2, a bracket 3, a drive shaft 4 and a stirring blade 5. The bracket 3 is fixed inside the reactor body 1, the stirring blade 5 is fixed to the side of the drive shaft 4, the drive shaft 4 is rotatably arranged on the bracket 3, the guide rod 2 is arranged inside the reactor body 1, and the top end of the guide rod 2 extends into the drive shaft 4 and cooperates with the drive shaft 4 through a traction member. The flipping assembly includes two drive rods 6, and a flap 7 equidistantly fixed between the two drive rods 6. The surface of the flap 7 is provided with a through groove 8. The drive rod 6 is connected to the reactor body 1 through a driving mechanism. The traction member includes a guide groove 14 and a spherical protrusion 15. The spherical protrusion 15 is arranged on the top of the guide rod 2, the guide groove 14 is arranged on the inner wall of the drive shaft 4, the spherical protrusion 15 is slidably arranged in the guide groove 14, the guide groove 14 is spirally wound around the surface of the guide rod 2, and the projection of the guide groove 14 on the cross section of the guide rod 2 is a perfect circle.

[0028] See also Figure 2 and 5The guide rod 2 can perform vertical reciprocating movement under the drive of the driving mechanism. When moving, the guide rod 2 can drive the spherical protrusion 15 to move synchronously. Since the driving shaft 4 and the bracket 3 are rotatably connected, the driving shaft 4 will not move axially. Therefore, under the drive of the spherical protrusion 15, the spherical protrusion 15 can gradually rise along the path of the guide groove 14 inside the guide groove 14. At this time, under the drive of the spherical protrusion 15, the driving shaft 4 as a whole can rotate circumferentially, and then the driving shaft 4 drives the stirring blade 5 to rotate synchronously, so as to stir the raw materials inside the reactor body 1 through the stirring blade 5.

[0029] See also Figure 3 and 4 The driving rod 6 can also perform vertical reciprocating motion under the drive of the driving mechanism, and then drive the flap 7 to move synchronously through the driving rod 6. Since the surface of the flap 7 is provided with a through groove 8 and the flap 7 is inclined, the flap 7 can flip the raw materials at the bottom of the reactor body 1 at this time, and mix the raw materials again in a movement mode different from that of the stirring blade 5, so as to improve the uniformity of the raw material mixing.

[0030] The driving mechanism includes a connecting rod 9, a swing arm 10, a rocker 11 and a rotating shaft 12. The rotating shaft 12 rotates on the inner wall of the reactor body 1, one end of the swing arm 10 is fixed to one end of the rotating shaft 12, one end of the rocker 11 is hinged to the swing arm 10, both ends of the connecting rod 9 are fixed to one end of the rocker 11, the top of the driving rod 6 is slidably set on the connecting rod 9, the bottom of the guide rod 2 is vertically fixed on the connecting rod 9, and the outer wall of the reactor body 1 is provided with a power source for driving the rotating shaft 12. The power source is set to a motor 13, and the motor 13 is fixed to the surface of the reactor body 1 through a frame. The output end of the motor 13 is key-connected with the rotating shaft 12, and a sliding sleeve 16 is fixedly set on the inner wall of the reactor body 1, and the sliding sleeve 16 is slidably set on the surface of the driving rod 6.

[0031] See also Figure 2 and 3 The motor 13 can drive the rotating shaft 12 to rotate, and the rotating shaft 12 can drive the swing arm 10 to rotate axially. When the swing arm 10 rotates, it can drive one end of the rocker 11 to rotate synchronously. Since the bottom of the rocker 11 is connected to the connecting rod 9, and the bottom of the connecting rod 9 is connected to the driving rod 6, and the driving rod 6 is limited by the sliding sleeve 16, so that the driving rod 6 can only perform vertical reciprocating motion, the swing arm 10 can only drive the top of the rocker 11 to rotate, and make the bottom of the rocker 11 move vertically, thereby realizing the driving of the driving rod 6 through the connecting rod 9.

[0032] Working principle: when in use, the raw material is introduced into the reactor body 1, and then the motor 13 is started. The motor 13 can drive the rotating shaft 12 to rotate, and the rotating shaft 12 can drive the swing arm 10 to rotate axially. When the swing arm 10 rotates, it can drive one end of the rocker 11 to rotate synchronously, so that the bottom end of the rocker 11 drives the connecting rod 9 to perform vertical reciprocating motion. At this time, the connecting rod 9 can simultaneously drive the guide rod 2 and the driving rod 6 to perform vertical reciprocating motion synchronously, and the driving rod 6 drives the flap 7 to move synchronously. Since the surface of the flap 7 is provided with a through groove 8, and the flap 7 is inclined, the flap 7 is When the guide rod 2 moves, the raw materials at the bottom of the reactor body 1 can be turned over, and the guide rod 2 can drive the spherical protrusion 15 to move synchronously. Since the drive shaft 4 and the bracket 3 are rotatably connected, the drive shaft 4 will not move axially. Therefore, under the drive of the spherical protrusion 15, the spherical protrusion 15 can gradually rise along the path of the guide groove 14 inside the guide groove 14. At this time, under the drive of the spherical protrusion 15, the drive shaft 4 as a whole can rotate circumferentially, and then the driving shaft 4 drives the stirring blade 5 to rotate synchronously, so as to stir the raw materials inside the reactor body 1 through the stirring blade 5.
