High-efficiency high-concentration non-clogging pulp pump

Abstract

The invention discloses a high-efficiency, high-concentration non-clogging pulp pump. One end of the rotating shaft close to the liquid inlet of the pump body is a connecting end, and the other end of the rotating shaft is used to connect a driving device. The screw booster propeller and the impeller are coaxially sleeved Set and fixed on the outer circumference of the rotating shaft, and the screw booster propeller and the impeller are arranged in sequence along the axial direction of the rotating shaft, the screw booster propeller is fixed near the connection end, and one end of the impeller is connected to the end of the screw booster propeller away from the liquid inlet abutting, the other end of the impeller extends away from the screw booster propeller, the driving device can drive the rotating shaft to rotate, and drive the screw booster propeller and the impeller to rotate, the screw booster propeller is used to push the slurry to move to the impeller, The impeller is used to push the slurry out through the liquid outlet, and a cooling element is arranged on the rotating shaft, and the cooling element is used to cool the rotating shaft. The high-efficiency high-concentration non-clogging pulp pump conveys high pulp concentration, high efficiency, long service life, and effectively guarantees production quality.

Description

technical field [0001] The invention relates to the technical field of pumps, in particular to a high-efficiency, high-density non-clogging pulp pump. Background technique [0002] Pulp pumps are widely used in the paper industry. Factors such as their operation stability and service life closely affect the quality of paper products. [0003] The existing pulp pump only provides the flow power of the slurry medium through the impeller, and the power is small, so that the slurry blockage and gas accumulation are prone to occur at the liquid inlet, which affects the service life of the pulp pump; in addition, due to the long shaft in the pulp pump Running at high speed for a long time will easily lead to its own temperature being too high, which will also affect its service life and the quality of the slurry. Contents of the invention [0004] The object of the present invention is to provide a high-efficiency, high-concentration, non-clogging pulp pump to solve the problem...
