The top end of the stirring shaft passes through the top wall of the vessel and is connected to the output end of the drive mechanism. A plurality of stirring rods are arranged at intervals along the axial direction of the stirring shaft and fixed on the stirring shaft body. The sliding sleeve is slidably connected to the bottom of the stirring shaft along the height direction of the vessel body.
[0013] Preferably, each set of the bottom-turning components is located in the same horizontal plane.
[0014] Preferably, the wave number of the annular wavy groove is an integer multiple of the number of the bottom-turning components.
[0015] Preferably, the bottom agitation assembly includes an agitation shaft and agitation blades. The agitation shaft is arranged perpendicular to the stirring shaft and one end is fixed to the outer wall of the sliding sleeve, while the other end is slidably connected to the wavy annular groove.

The end of the flipping shaft away from the sliding sleeve passes through the sliding hole and is slidably connected to the wavy groove, so as to drive the scraper to scrape the inner side wall of the vessel body.
[0020] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a high-efficiency chemical reaction vessel, which can stir the material in the vessel while the bottom stirring component moves up and down to stir the material at the bottom of the vessel, thus preventing the material from settling at the bottom of the vessel.

[0031] Stirring component 2 is installed inside the vessel body;
[0032] Sliding sleeve 3 is slidably connected to the bottom of stirring assembly 2 along the height direction of the vessel body 1;
[0033] Bottom-turning component 4: Multiple sets of bottom-turning components 4 are evenly spaced around the outer periphery of the sliding sleeve 3. One end of each component is fixed to the sliding sleeve 3, and the other end is slidably connected to the annular wave-shaped groove 11.
[0034] While the stirring component 2 rotates and stirs, it drives the bottom turning component 4 to rotate synchronously. Due to the constraint of the wave-shaped chute, the bottom turning component 4 floats up and down while rotating around the stirring component 2, so as to turn the material at the bottom of the vessel and prevent the material from settling at the bottom of the vessel.
[0035] In one specific embodiment, the stirring assembly 2 includes a drive unit 23, a stirring shaft 21, and stirring rods 22. The drive unit 23 is a geared motor.

Multiple stirring rods 22 are arranged at intervals along the axial direction of the stirring shaft 21 and are fixed to the shaft body of the stirring shaft 21. A sliding sleeve 3 is slidably connected to the bottom of the stirring shaft 21 along the height direction of the vessel body 1. This stirs the materials in the vessel, promotes uniform mixing of the materials, and improves the reaction efficiency of the materials.
[0036] In one specific embodiment, each set of bottom-turning components 4 is located on the same horizontal plane. The number of waves in the annular wavy chute 11 is an integer multiple of the number of bottom-turning components 4. When all the turning components rotate with the stirring shaft 21, they can simultaneously be located on any horizontal plane, such as the trough or crest, within the annular wavy chute 11.
[0037] In one specific embodiment, the bottom agitation assembly 4 includes an agitation shaft 41 and agitation blades 42. The agitation shaft 41 is arranged perpendicular to the stirring shaft 21 and one end is fixed to the outer wall of the sliding sleeve 3, while the other end is slidably connected to a wave-shaped annular groove.

The baffle plate 422 is used to enhance the disturbance of the material at the bottom of the vessel.
[0039] In one specific embodiment, the spoiler 422 is a straight plate or an arc-shaped plate with a raised bottom surface.
[0040] In one specific embodiment, a follower assembly is also provided, which includes a follower shaft 423 and follower blades 424. A mounting hole is provided in the center of the baffle 422. The follower shaft 423 is arranged parallel to the flipping shaft 41 and rotatably mounted in the mounting hole. The follower blades 424 are evenly spaced circumferentially and fixed to the follower shaft 423. While the baffle 422 floats up and down, it can utilize the disturbance of the fluid material to drive the follower blades 424 to rotate, improving the flipping efficiency, enhancing the material mixing effect, and improving the reaction efficiency.
[0041] In one specific embodiment, a scraper 5 is also included. The top of the scraper 5 is slidably connected to the inner top wall of the vessel body 1, and the bottom is slidably connected to the inner bottom wall of the vessel body 1.
