Embodiment Construction

[0026] see Figure 1 to Figure 7 , the non-blocking water inlet pipe of the sewage pump according to an embodiment of the present invention includes a water inlet elbow 2 connected to the water inlet of the sewage pump 1, and a water inlet elbow 2 is arranged along the inner wall of the flow channel to divide it into upper and lower two. The diversion rib 3 of the flow channel, the inlet side of the diversion rib 3 is a hypotenuse, the angle between the hypotenuse and the busbar of the water inlet elbow 2 is 70°, and the side of the water inlet elbow 2 is equipped with a filter that can suck and shred dirt. The circular groove convex shape cutting chamber 4.

[0027] The cutting chamber 4 is provided with a static knife 5, a moving knife 6, a rotating shaft 8, a centrifugal blade 7, a cutting chamber cover plate 9 and a motor 10, and the static knife 5 includes a stationary annular flat plate 51, which is evenly set on the periphery of the annular flat plate 51. 4-8 arc-shape...

Abstract

The invention discloses a blockage-free water inlet pipe of a sewage pump. The blockage-free water inlet pipe comprises a water inlet bend connected with a water inlet of the sewage pump. A flow guiding rib for dividing a water inlet bend runner into an upper branch runner and a lower branch runner is arranged along the inner wall of the water inlet bend runner, and a groove protrusion-shaped cutting chamber capable of sucking in and shredding dirt is arranged on the side edge of the water inlet bend, and the cutting chamber is provided with a fixed cutter and a movable cutter which can be used in cooperation and further provided with a centrifugal blade capable of sucking dirt into the cutting chamber. The blockage-free water inlet pipe of the sewage pump can stabilize the large-flow water inlet state; fiber and other winding dirt on the inlet edge of the flow guiding rib can be efficiently sucked in and subjected to cutting treatment; and the blockage-free water inlet pipe is suitable for large-flow dirt discharging and is high in dirt discharging efficiency.

Description

technical field [0001] The invention relates to the technical field of sewage pumps, in particular to a non-blocking water inlet pipe of the sewage pump. Background technique [0002] In industrial production, the submersible sewage pump has obvious advantages such as compact structure, less cavitation damage, low vibration and noise, and no pollution. Domestic sewage, industrial wastewater, construction site drainage, liquid feed, etc., play an obvious role in all walks of life. However, when the sewage pump is transporting sewage, there are often various fibers and plastic products such as cotton yarn, hemp rope, and rags in the sewage. Once these impurities block the water inlet, it will easily lead to unsmooth sewage discharge, which seriously even affects the operation of the submersible sewage pump. Normal operation will cause damage to the motor and reduce the working efficiency and service life of the submersible sewage pump. [0003] In order to prevent the fiber ...
