Crushing and separating type sewage pump

Abstract

The invention discloses a crushing and separating type sewage pump. The crushing and separating type sewage pump comprises a sewage pump shell, cylindrical crushers, a left trapezoidal crushing recoverer, a right trapezoidal crushing recoverer, an impeller crusher and an impeller. The sewage pump shell is provided with an outlet flow channel, an upper side inlet flow channel and a lower side inlet flow channel, the upper side inlet flow channel and the lower side inlet flow channel are symmetrically arranged, the cylindrical crushers are located in the upper side inlet flow channel and the lower side inlet flow channel correspondingly, and the left trapezoidal crushing recoverer and the right trapezoidal crushing recoverer are sequentially arranged in the sewage pump shell in the water flow direction. The upper side inlet flow channel and the lower side inlet flow channel are separated by the sewage pump shell and are independent of each other. The upper side inlet flow channel and the lower side inlet flow channel are both gradually-shrunk conical flow channels. In the sewage discharge process, sundries and sewage can be effectively separated, and meanwhile, the sundries are collected and discharged.

Description

technical field [0001] The invention relates to a one-way valve, in particular to a broken and separated sewage pump. Background technique [0002] Sewage pumps are widely used in daily life and industrial sewage discharge. However, during the process of conveying sewage, the sewage pump is often entangled with the rotating shaft by plastic bags, ropes and other sundries in the sewage. In severe cases, the rotating shaft stops, which affects the discharge. At the same time, the particles in the sewage hit the blades and cause serious blade wear. , the particles may also cause blockage of the flow channel during the sewage discharge process. [0003] However, most of the sewage pumps in the current technology are equipped with impellers, which use the impellers to crush debris, and the crushed debris is discharged together with the sewage. However, after a long period of use, when the impeller is worn, the crushing force is weakened, and the debris cannot be crushed. When t...

Problems solved by technology

However, in the process of conveying sewage, the sewage pump is often entangled with the rotating shaft by plastic bags, ropes and other sundries in the sewage. In severe cases, the rotating shaft stops, which affects the discharge. At the same time, the particles in the sewage hit the blades and cause serious wear of the blades. , the particles may also cause blockage of the flow channel during the sewage discharge process

[0003] However, most of the sewage pumps in the current technology are equipped with impellers, which use the impellers to crush debris, and the crushed debris is discharged along with the sewage. However, after a long period of use, when the impeller wears out, the crushing force is weakened, and the debris cannot be crushed. When the debris will block the flow channel and affect the sewage discharge; that is, the effective separation of debris and sewage cannot be achieved in the prior art, the work efficiency is low, and the loss of energy consumption is large
