This utility model discloses a multi-stage centrifugal pump guide vane assembly and a multi-stage centrifugal pump, including a centrifugal pump body. The centrifugal pump body is generally divided into a motor and an impeller mechanism. A drive shaft is fitted and connected to the end of the motor near the impeller mechanism, and a reinforcing sleeve is fitted and connected to the outer side of the drive shaft. An impeller shaft is fitted and connected to the end of the impeller mechanism near the motor. A threaded sleeve is fixedly installed on the outer surface of the impeller shaft, and a connection port is opened on the inner side of the threaded sleeve. A plug is fixedly connected to the end of the drive shaft near the impeller shaft. The reinforcing sleeve has a connecting thread inside. By setting the drive shaft, impeller shaft, and connection port, this device improves the power transmission efficiency and simplifies the docking and installation process between the motor and the impeller mechanism. Furthermore, by setting the reinforcing sleeve, limiting sleeve, and retaining ring, the connection stability between the drive shaft and the impeller shaft is enhanced by limiting the axial displacement of the retaining ring after docking.

This utility model relates to the field of crushing and pulverizing technology, and particularly to a multi-stage rotary crushing and pulverizing machine. It includes a support frame, a processing shell fixedly mounted on the upper end of the support frame, a discharge shell fixedly mounted on the lower end face of the processing shell, and two sets of crushing rollers symmetrically mounted within the processing shell. A first drive motor is fixedly mounted on one end of the processing shell, and a linkage assembly connecting the two sets of crushing rollers is provided at the other end of the processing shell. A pulverizing shell is detachably mounted on the lower end face of the discharge shell. This application, by setting a multi-stage pulverizing structure, including two sets of crushing rollers, two sets of main pulverizing rollers, and several auxiliary pulverizing rollers, enables multiple crushing and pulverizing processes on materials, greatly improving the pulverizing effect. The material is subjected to different forces at different pulverizing stages, such as compression, shearing, and rotary cutting, ensuring that the material is fully pulverized and meeting the needs of different industrial production and resource recycling.

The utility model discloses a filter cloth production pressing mechanism which comprises a base, a pair of supporting plates are arranged on the upper wall of the base, a lower roller shaft is rotationally installed between the supporting plates, an upper roller shaft is arranged above the lower roller shaft, and pressing rollers are installed on the lower roller shaft and the upper roller shaft. The telescopic end of an electric push rod in the adjusting assembly is fixedly connected with a connecting frame of the sliding box, the vertical position of the sliding box can be accurately adjusted by controlling stretching and retracting of the electric push rod, then an upper roller shaft is driven to move vertically, the distance between the upper roller shaft and a lower roller shaft is adjusted, and use of filter cloth with different thicknesses is met; a transmission shaft in a main shaft in the driving assembly is meshed with a second transmission gear of the upper roll shaft through a second driving gear, power is transmitted to the upper roll shaft, the transmission mode ensures that the upper roll shaft and the lower roll shaft can still rotate relatively after the distance is adjusted, the stability of power transmission is ensured, the pressing effect is improved, and the production quality is ensured.
