[0032] A method for designing a high-efficiency hydrocyclone comprises the following steps: S1. Material selection: select suitable materials; S2.

Inspection: size and rough surface inspection to ensure design standards; S6, coating treatment: spraying corrosion-resistant coating; S7. Final inspection and packaging: After passing the comprehensive inspection, the products are packaged appropriately and the relevant information is marked.

[0033] Working principle: First, the cone to be sprayed is placed on the first placement plate 203 through an external loading mechanism, and then the motor 225 is started to make the motor 225 start working. The end of the output shaft of the motor 225 rotates to drive the No. 1 rotating rod 221 to rotate. The rotation of the No. 1 rotating rod 221 first drives the No. 1 gear 224 that is meshed with each other to rotate. The rotation of the No. 1 gear 224 drives the No. 2 rotating rod 223 to rotate. The rotation of the No. 2 rotating rod 223 causes the No. 2 rotating shaft 210 to rotate through the synchronous wheel and the synchronous belt. The rotation of the No. 2 rotating shaft 210 drives the groove wheel 204 and the rotating plate 212 to rotate. The rotation of the rotating plate 212 drives the fixed rod 213 to rotate. 213. The slot 205 and the notched disc 211 drive the groove wheel 204 to rotate a quarter of a circle. The groove wheel 204 rotates a quarter of a circle to drive the rotating frame 202 to rotate a quarter of a circle. The rotating frame 202 rotates to drive the placement plate 203 to rotate. The placement plate 203 rotates while driving the No. 1 transmission rod 310 to rotate in a circle. The No. 1 transmission rod 310 rotates in a circle to drive the No. 2 gear 311 to rotate in a circle when passing through the inner gear ring 312. The No. 2 gear 311 rotates by itself. The rotation of the No. 1 transmission rod 310 drives the threaded rod 301 to rotate. The rotation of the threaded rod 301 drives the threaded sleeve rod 302 to rotate with the assistance of the connecting plate 303. The threaded sleeve 302 moves upward and drives the four clamping plates 304 to move outward through the connecting plate 303. The clamping plates 304 move outward to position the cone, and the cone on the placement plate 203 can be clamped from the inside to the outside, avoiding the problem of multiple operations that are more cumbersome, thereby achieving the purpose of improving operating efficiency. When the cone moves to the inside of the spraying mechanism 4, at this time, the half-face gear 222 drives the third gear 406 to rotate, and the rotation of the third gear 406 drives the second transmission rod 405 to rotate, and the rotation of the second transmission rod 405 causes the rotating sleeve rod 402 to rotate through the synchronous wheel and the synchronous belt, and the rotating sleeve rod 402 rotates to drive the mounting frame 403 rotates, which can drive the nozzle 404 to rotate around the cone. At the same time, the corrosion-resistant coating is transmitted to several nozzles 404 through the pump body 411 through the delivery pipe 412, and then sprayed to the outside of the cone by the nozzle 404, which can drive the nozzle 404 to rotate around the cone to be sprayed, so as to achieve the purpose of spraying the outside of the cone more evenly. At the same time, when the second gear 311 passes through the outer gear ring 313, the threaded rod 301 flips, which can drive the clamping plate 304 to move inward, thereby losing the clamping of the cone, and then the cone that has been sprayed can be removed by the unloading equipment, so that work can be continued uninterruptedly.

[0034] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
