[0022] like Figures 1 to 5As shown, a reactor shaking device for preparing powder catalyst by sol-gel method comprises a bottom plate 1, a support platform 2, a first limit plate 13, a second limit plate 14, an annular electromagnet 23, a gear ring 27 and a first motor 28. A second support plate 12 is installed on the top side of the bottom plate 1, and a first support plate 11 is installed on the bottom side of the support platform 2. The first support plate 11 and the second support plate 12 are rotatably connected. The bottom plate 1 and the side of the support platform 2 away from the first support plate 11 are connected by a disturbance component. The support platform 2 is driven to reciprocate up and down around the bottom plate 1 relative to the connection between the first support plate 11 and the second support plate 12 by the disturbance component, thereby driving the support platform 2 as a whole to achieve a small range of reciprocating shaking operation. , a plurality of guide components 5 are connected between the bottom plate 1 and the support platform 2, and the guide components 5 can provide guidance for the relative rotation between the bottom plate 1 and the support platform 2. A spherical head 25 is installed at the bottom of the first limit plate 13, and a support seat 26 is installed at the top of the support platform 2. The spherical head 25 and the support seat 26 rotate together to support the first limit plate 13. A gear ring 27 installed on the support platform 2 is arranged on the outer side of the support seat 26. A circumferential shaking component is installed at the bottom of the first limit plate 13, and the axial shaking component is meshed with the gear ring 27. A plurality of support components 3 are installed on the side of the first limit plate 13 away from the circumferential shaking component, and the support component 3 is meshed with the gear ring 27. The support assembly 3 is used to maintain the overall stability of the first limit plate 13 while supporting the bottom of the first limit plate 13 away from one side of the circumferential shaking assembly, so that the circumferential shaking assembly and the gear ring 27 are closely matched. The first limit plate 13 and the second limit plate 14 are parallel to each other. The second limit plate 14 is located at the top of the first limit plate 13 and is connected to the first limit plate 13 through two pairs of guide columns 15 on both sides.

The first guide rod 35 slides with the first guide sleeve 34. A second spring 36 is connected between the first mounting block 31 and the positioning block 33. The second spring 36 is in a compressed state, so that the first mounting block 31 and the positioning block 33 have a tendency to move away from each other in a free state. A roller 37 is rotatably mounted on the bottom of the bracket 32. The roller 37 meshes with the gear ring 27, so as to realize pre-tightening of the meshing between the driving gear 29 and the gear ring 27 while preventing the first limit plate 13 from tipping over, so that the circumferential rotation of the first limit plate 13 remains stable.

[0029] When the device is working, the controller 6 drives the annular electromagnet 23 to intermittently turn on and off the power, and cooperates with the first spring 22 to realize the reciprocating oscillation of the reactor 4 between the first limit plate 13 and the second limit plate 14; the controller 6 energizes the first motor 28 to realize the engagement of the driving gear 29 and the gear ring 27 to drive the reactor 4 to perform a deflection circular motion; the controller 6 energizes the second motor 42 to realize the reciprocating swing of the support platform 2 relative to the bottom plate 1; the reciprocating oscillation of the reactor 4 between the first limit plate 13 and the second limit plate 14, in conjunction with the deflection circular motion and the reciprocating swing in the vertical direction, can accelerate the shaking speed and uniformity of the reagents in the reactor 4.

[0030] Heating tubes are embedded in the bottom and sides of the reactor 4, and the materials in the reactor 4 can be heated during the shaking process through the heating tubes. Exhaust holes are provided on the top cover plate of the reactor.
