Abstract
The utility model discloses a screw pump for pumping solid particles. The screw pump comprises a pump shell, a rotor and a transmission shaft. The rotor is installed inside the pump shell. One end of the rotor is located in a discharging outlet of the pump shell, and the other end of the rotor is connected with the transmission shaft. A screw is arranged on the rotor. The screw is composed of a plurality of grooves. The cross section of each groove is trapezoid. According to the screw pump for pumping the solid particles, due to the fact that the screw with the trapezoid cross section is arranged on the rotor, the transmission shaft transmits power input by a motor to the rotor to drive the rotor to rotate, the solid particles move along the grooves, the solid particles are discharged out of a pump cavity from the discharging outlet through the screw, the solid particles are directly pumped, one end of the rotor is located in the discharging outlet, the mode that the two ends of a rotor of a traditional screw pump are fixed is changed, a bearing pedestal and a bearing are arranged in a shaft hole, and the transmission shaft is sleeved with the bearing. Due to the structure, only one bearing is used, compared with the prior art, the structure is easier and more reasonable, and the solid particle pumping efficiency is higher.
