Mixed-flow pump with cutting anti-blocking function

Abstract

The invention relates to the technical field of mixed-flow pumps, and discloses a mixed-flow pump with a cutting anti-blocking function. The mixed-flow pump comprises a carrier plate and a cushion plate. Two supporting rods are fixedly mounted on the top of the carrier plate, the tops of the two supporting rods are fixedly connected with a mixed-flow pump body, a water inlet of the mixed-flow pumpbody communicates with a stretching pipe, the right side of the stretching pipe communicates with a water inflow pipe, a waterproof cover is fixedly mounted on the top of the water inflow pipe, a drive motor is fixedly mounted at the position, in the waterproof cover, of the top of the water inflow pipe, and a rotary shaft with one end stretching out of the waterproof cover is fixedly mounted atthe output end of the drive motor. According to the mixed-flow pump with the cutting anti-blocking function, through the arrangement of the waterproof cover, the rotary shaft and cutting knives, the mixed-flow pump body extracts water through the water inflow pipe, when impurities are accumulated at the water inflow position of the water inflow pipe, the drive motor drives the cutting knives to rotate, branches and other impurities are smashed through the cutting knives, and therefore the water inflow pipe cannot be blocked.

Description

technical field [0001] The invention relates to the technical field of mixed-flow pumps, in particular to a mixed-flow pump with cutting and anti-clogging functions. Background technique [0002] The mixed-flow pump is a pump between the centrifugal pump and the axial-flow pump. The specific speed of the mixed-flow pump is higher than that of the centrifugal pump and lower than that of the axial-flow pump, generally between 300-500. Its lift is higher than that of the axial-flow pump. , but the flow rate is smaller than that of the axial flow pump and larger than that of the centrifugal pump. When the prime mover drives the impeller to rotate, the action on the liquid has both centrifugal force and axial thrust. It is a combination of the centrifugal pump and the axial flow pump, and the liquid flows out of the impeller obliquely . [0003] When the mixed-flow pump is pumping water, if it is sewage, there are impurities such as branches in the sewage. These impurities block...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a mixed-flow pump with cutting and anti-clogging functions, which has the advantages of cutting and anti-clogging functions, and solves the problem that if the mixed-flow pump pumps water, if it is sewage, there are branches and other impurities in the sewage. These impurities block the water inlet and then block small garbage such as leaves, and eventually cause the water inlet to be completely blocked, which is quite annoying for users.
