Embodiment 1

[0030] Such as figure 1 , 2 . As shown in 3, a swivel cutting pump includes a pump body 1, an impeller 2, and a medium separation structure arranged at the front end of the impeller 2, and the medium separation structure includes a swivel cutting knife 4 and a fixed cutting knife;

[0031] The swivel cutter 4 is arranged at the water inlet at the front end of the impeller 2 through the cutter fixing mechanism 10, and the impeller 2 drives the swivel cutter 4 to rotate together to chop the medium entering the impeller 2;

[0032] Described fixed ripper comprises inner side ripper 7, outer side ripper 8, at least one described inner side ripper 7 is arranged on the inner side of described swastika cutting knife 4, and at least one described outer side ripper 8 is arranged on The outside of the four-character cutting knife 4.

[0033] Preferably, the front end of the impeller 2 is extended with a tubular groove 6, and at least one set of housing support plates 5 are arranged sy...

Embodiment 2

[0038] Compared with Example 1, as Figure 4 As shown, in Embodiment 2, a plurality of the four-digit cutting knives 4 are arranged side by side at the end of the tubular groove 6 , and a gap is maintained between the multiple four-digit cutting knives 4 .

[0039] Preferably, the outer trimming knife 8 is arranged at a gap between a plurality of the swivel cutters 4, so as to prevent the belt-shaped medium from being entangled at the gap.

[0040] Preferably, the four outer cover support plates 5 are evenly distributed on the outer circumferential arm of the tubular groove 6, one outer trimmer 7 is mounted on one of the outer cover support plates 5, and three inner trimmers Knives 8 are respectively installed on three of them on the cover support plates 5 .

[0041] Preferably, as Figure 5 , 7 As shown, the internal fixed trimmer 9 includes an arc-shaped fixing block 91, a working blade 92, and a fixing screw 93; the arc-shaped fixing block 91 fits with the inner wall of ...

Abstract

The invention discloses a fylfot cutting pump. The fylfot cutting pump comprises a pump body, an impeller and a medium separation structure arranged at the front end of the impeller, wherein the medium separation structure is composed of fylfot cutters and a fixing texture cutter; the fylfot cutters are arranged at corresponding water inlets formed in the front end of the impeller; the impeller drive the fylfot cutters to rotate together so as to cut up media which enter the impeller; the fixing texture cutter is composed of inner side texture cutters and outer side texture cutters; at least one inner side texture cutter is arranged on the inner side of each fylfot cutter; and at least one outer side texture cutter is arranged on the outer side of each fylfot cutter. With adoption of dynamic design of the water inlets, the fylfot cutting pump has the characteristics that the water inlets cannot be blocked, a rotary shaft cannot be twined to cause overload of a motor, and the discharge rate of the media is large.

Description

technical field [0001] The invention relates to the technical field of sewage pumps, in particular to a swivel cutting pump. Background technique [0002] Sewage pumps are mainly used to transport ①domestic sewage with discarded shopping bags, sanitary napkins, and broken socks; ②aquaculture excrement with various hairs, residual grass, and bamboo sticks; Fish pond silt; ④Urban sewage discharge with fine wire, foam blocks, branches and leaves. Because the conveyed medium contains fibers that are easy to entangle or bunch, the flow path of this kind of pump is easy to be blocked. Once the pump is blocked, the pump will not work normally, and even the motor will be burned, resulting in poor sewage discharge, which is harmful to urban life and Environmental impacts are serious. Therefore, anti-clogging and reliability are important factors for the quality of sewage pumps. Generally, a tearing mechanism is installed on the sewage pump, which can tear and cut off the fibrous m...
