[0029] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following will further describe the implementation manners of the present utility model in conjunction with the accompanying drawings in detail.

[0030] The present utility model provides a catalyst slurry dispersion device. While the motor drives the stirring shaft to revolve, the stirring shaft meshes with the internal gear ring through the gear to realize self-rotation, and performs double-axis mixing and stirring on the catalyst slurry, avoiding the rotation of the catalyst slurry in a single direction and improving the dispersion effect. Please refer to Figures 1-5, including: a dispersion barrel 100, a barrel cover 200, and a planetary stirring mechanism 300.

[0031] The dispersion barrel 100 is used to hold the catalyst slurry.

[0032] The barrel cover 200 is arranged on the top of the dispersion barrel 100. The barrel cover 200 includes a cover plate 210, a motor 220, an output shaft 230, and an internal gear ring 240. The motor 220 is arranged at the center of the top of the cover plate 210. The output end of the motor 220 is provided with an output shaft 230 extending into the dispersion barrel 100. The internal gear ring 240 is arranged at the bottom of the cover plate 210;

[0033] Among them, the motor 220 drives the output shaft 230 to rotate, providing rotational power.

[0034] The planetary stirring mechanism 300 is arranged on the output shaft 230. The planetary stirring mechanism 300 includes a bracket 310, a stirring shaft 320, a gear 330, and a stirring blade 340. The center of the bracket 310 is fixedly connected to the output shaft 230. Both ends of the bracket 310 are rotatably connected to the stirring shaft 320. Gears 330 meshing with the internal gear ring 240 are arranged at the tops of the stirring shafts 320. Stirring blades 340 are arranged on the outer walls of the lower ends of the stirring shafts 320;

[0035] Among them, when the output shaft 230 rotates, it drives the bracket 310 to rotate. The stirring shafts 320 follow the rotation of the bracket and perform a revolution around the output shaft 230. During the revolution, the gears 330 mesh with the internal gear ring 240, driving the stirring shafts 320 to rotate self - rotatably. The self - rotating stirring shafts 320 drive the stirring blades 340 to rotate.

[0036] Since it is necessary to input and discharge the catalyst slurry, the dispersion barrel 100 includes a barrel body 110 and a discharge pipe 120. The bottom of the side wall of the barrel body 110 is connected to the discharge pipe 120. A feed pipe 250 is arranged on the cover plate 210. Control valves are arranged on both the discharge pipe 120 and the feed pipe 250. Feeding and discharging are carried out through the feed pipe 250 and the discharge pipe 120, and the discharge and feed amounts are controlled by the control valves.

[0037] Since the planetary stirring mechanism 300 can only perform horizontal stirring and cannot transport the slurry at the bottom to the top to achieve vertical circulation, a lifting pipe 130 is arranged at the bottom of the inner cavity of the barrel body 110. Uniformly distributed through - slots 140 are opened on the bottom side wall of the lifting pipe 130. A spiral shaft 400 is arranged at the center of the bottom of the bracket 310. The spiral shaft 400 is inserted into the interior of the lifting pipe 130;

[0038] When the bracket 310 rotates, it drives the spiral shaft 400 to rotate. The rotating spiral shaft 400 forms a spiral feeding mechanism inside the lifting pipe 130, sucking the catalyst slurry at the bottom into the lifting pipe 130 through the through - slots 140 and then discharging it from the top of the lifting pipe 130, driving the catalyst slurry to perform vertical circulation.

[0039] To reduce the frictional resistance, bearings are provided at the connection positions between the cover plate 210 and the output shaft 230, and between the bracket 310 and the stirring shaft 320, facilitating the rotation of the output shaft 230 and the stirring shaft 320.

[0040] To facilitate the connection of the cover plate 210, the outer side wall of the internal gear ring 240 is fitted with the top opening of the barrel body 110, and the internal gear ring 240 is connected to the barrel body 110 as a fitting.

[0041] To facilitate observing the internal dispersion state, a transparent viewing window is provided on the outer wall of the barrel body 110, and the dispersion state of the catalyst slurry inside the barrel body 110 is observed through the transparent viewing window.

[0042] During specific use, the catalyst slurry is put into the barrel body 110 through the feed pipe 250. The motor 220 drives the output shaft 230 to rotate. The output shaft 230 drives the bracket 310 to rotate, and the stirring shaft 320 rotates following the bracket, performing a revolution around the output shaft 230. During the revolution, the gear 330 meshes with the internal gear ring 240, driving the stirring shaft 320 to rotate self - rotatably. The self - rotating stirring shaft 320 drives the stirring blades 340 to rotate. At the same time, when the bracket 310 rotates, it drives the spiral shaft 400 to rotate. The rotating spiral shaft 400 forms a spiral feeding mechanism inside the riser 130, sucking the catalyst slurry at the bottom into the riser 130 through the through - slot 140 and then discharging it from the top of the riser 130, driving the longitudinal circulation of the catalyst slurry, stirring while lifting, and uniformly dispersing the catalyst slurry.

[0043] Although the present utility model has been described with reference to the embodiments above, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the various features in the disclosed embodiments of the present utility model can be combined with each other in any way. The reason for not exhaustively describing the situations of these combinations in this specification is only to save space and resources. Therefore, the present utility model is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
