Vertical type sewage pump

Abstract

The invention discloses a vertical type sewage pump. The vertical type sewage pump comprises a pump body and a high-speed motor, wherein a sound insulation cover is arranged at the outer side of the high-speed motor in a covering manner; metal heat absorbing plates are arranged at the two sides of the interior of the sound insulation cover; heat dissipation rods which extend to the exterior of thesound insulation cover are arranged on the metal heat absorbing plates; an output shaft of the high-speed motor is connected to a transmission shaft through a shaft coupling; an impeller is fixed atthe bottom end of the transmission shaft; a water inlet is formed in the bottom end of the outer surface of the pump body; a water outlet is formed in the upper end of the outer surface of the pump body; a filtering net is arranged between the air inlet and the impeller; and vibration motors are arranged on the side walls, located at the two sides of the filtering net, of the pump body, and are connected to the filtering net through a vibration transmission shaft. The vertical type sewage pump is simple in structure and convenient to use, has good sound insulation and noise reduction effects,and can effectively filter out impurities in sewage; and after the vertical type sewage pump is used for a long time, sundries adhered to the filtering net can be shaken off in a vibration manner, andthe removal of impurities on the filtering net is convenient.

Description

technical field [0001] The invention relates to the technical field of sewage pumps, in particular to a vertical sewage pump. Background technique [0002] The sewage pump is a kind of centrifugal impurity pump, which is mainly used to transport urban sewage. There are many types of sewage pumps, the common ones are horizontal sewage pumps and vertical sewage pumps. Compared with horizontal sewage pumps, vertical sewage pumps are widely used because of their small size, simple manufacture, and low cost. should be used. However, when the existing vertical sewage pump is working, the noise generated by the high-speed motor is large, which seriously affects the physical and mental health of the staff, and the impurities in the sewage cannot be filtered out. The sewage pump is easily blocked by impurities and cannot work normally. In addition, the existing For some sewage pumps with filters, a lot of debris will adhere to the filters after long-term use. If they are not cleane...
