All-dimensional sealing structure of impeller type wet spraying machine rotor body
The invention provides an all-dimensional sealing structure of an impeller type wet spraying machine rotor body. The all-dimensional sealing structure comprises the impeller rotor body, a fixed cavity body and a hollow middle shaft. The impeller rotor body is fixedly arranged on the hollow middle shaft in a sleeving mode. The hollow middle shaft is provided with air outlet holes. The fixed cavity body is arranged in the peripheral direction of the impeller rotor body. A protection steel sleeve is arranged between the impeller rotor body and the hollow middle shaft. The protection steel sleeve is fixedly arranged on the hollow middle shaft and provided with wind outlet openings corresponding to the air outlet holes of the hollow middle shaft. The two ends of the protection steel sleeve are provided with sleeve bodies in a sleeving mode. Sealing devices are arranged between the sleeve bodies and the protection steel sleeve. The inner side end faces of the sleeve bodies are provided with sealing elements, and the sealing elements are arranged on the protection steel sleeve in a sleeving mode. The outer side faces of the inner side ends of the sealing elements are provided with first grooves matched with protrusions at the lower end of the impeller rotor body. The sealing elements are positioned through the sleeve bodies and the impeller rotor body in the axial direction.
