Abstract
The utility model discloses a sewage pump with a cutting device, mainly suitable for conveying media with sundries such as fibre. The utility model comprises a pump body 1, a pump cover 2 and an arcuate metal plate 3; a pump shaft 4, and an impeller 5 and a motor 6 which are connected with the pump shaft 4 are arranged inside the pump body 1; the arcuate metal plate 3 with uneven thickness is connected with an inlet of the pump body 1 and is provided with a cutting blade. Firstly, because the arcuate metal plate 3 is arranged on the inlet of the pump body 1, the utility model plays a part in preventing from generating vortex on an inlet of the sewage pump; secondly, a movable cutting blade formed by a fixed cutting blade of the arcuate metal plate 3 fixed on the pump body 1 and an inlet end of an impeller 4 is used for cutting sundries such as fibre. The utility model can not only prevent from generating vortex on the inlet of the sewage pump but also cut sundries such as fibre, thereby, the sundries such as fibre are prevented from winding on the impellers to cause the blockage of the inlet of the pump, and a better cutting effect is achieved.
Description
Technical field
The utility model relates to mechanical sewage pump field, relates in particular to a kind of sewage pump with cutting device, is mainly used in to carry the medium that contains foreign material such as fiber.
Background technique
Sewage pump is widely used in the medium occasion that conveying contains foreign material; these sewage pumps can good transportation sanitary wastewaters, sewage and are contained the medium of suspended solids such as silt, wooden cave; but the existing existing major defect of most sewage pump is when containing the medium of longer foreign material such as fiber, thin branch in conveying; long foreign material such as fiber can be wrapped on the impeller; runner is stopped up; cause sewage pump efficient to reduce, can damage impeller when serious, cause the sewage pump compressor emergency shutdown.At present, some sewage pumps realize carrying the medium of foreign material such as length such as fibre-bearing grade by the area of passage that strengthens the impeller and the pump housing, are wrapped on the impeller but foreign material such as fiber also can appear in the sewage pump operation long period, cause phenomenons such as runner obstruction, impeller damage.Also have some sewage pumps to add to shear cutter head and add the tooth shear blade at the impeller back and wait and realize carrying the medium that contains longer foreign material, but these measures have increased the design and the processing charges of sewage pump, make these measures be difficult to be applied at the impeller place.
Summary of the invention
In order to overcome existing sewage pump when carrying the medium of longer foreign material such as fibre-bearing; long foreign material such as fiber can be wrapped on the impeller; make runner stop up; cause sewage pump efficient to reduce; can damage impeller when serious; cause shortcomings such as sewage pump compressor emergency shutdown; the utility model provides a kind of sewage pump with cutting device; the type sewage pump cutting device is simple in structure; easy for installation; good cutting effect can better solve sewage pump and be wrapped in the problem that causes the sewage pump fault on the impeller because of foreign material such as fibers when the medium of foreign material such as conveying fibre-bearing.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of sewage pump with cutting device, it comprises the pump housing 1, pump cover 2, arc sheetmetal 3 in the coupled became uneven band shear blade of the pump housing 1 inlet, pump shaft 4 is arranged, impeller 5 that links to each other with pump shaft 4 and motor 6 in the pump housing 1.The arc sheetmetal 3 of the became uneven band shear blade that the described pump housing 1 inlet installs, at first play the effect that prevents to produce in import vortex, the moving shear blade of secondly utilizing impeller 4 entrance points of the fixed shear blade that is fixed on arc sheetmetal 3 on the pump housing 1 and high speed rotating to be constituted is come foreign material such as shearing fibre.This type cutting device not only can prevent to produce in sewage pump inlet the danger of vortex, but foreign material such as shearing fibre simultaneously prevent that fiber etc. is wrapped on the impeller, cause the import of foreign material block pumps, cause very big volumetric loss, thereby reduce the fault of sewage pump.Shape and the position that can adjust arc sheetmetal according to the shape and the position on sewage pump impeller inlet limit simultaneously is so that obtain better shear effect.
The beneficial effects of the utility model are, compare with existing technology, and this type sewage pump cutting device is simple in structure, and is easy for installation, good cutting effect, and can prevent to produce vortex in the sewage pump import.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is that connection of the present utility model is always schemed.
As shown in the figure, 1. pump housings among the figure, 2. pump cover, the 3. arc sheetmetal of became uneven band shear blade, 4. pump shaft, 5. impeller, 6. motor.
Fig. 2 is arc sheetmetal 3 structural representations of became uneven band shear blade.
Embodiment
As shown in fig. 1, a kind of sewage pump with cutting device, it comprises the pump housing 1, pump cover 2, the arc sheetmetal 3 in the coupled became uneven band shear blade of the pump housing 1 inlet has pump shaft 4 in the pump housing 1, impeller 5 that links to each other with pump shaft 4 and motor 6.The pump housing 1 inlet top utilizes four screw that the arc sheetmetal 3 of a became uneven band shear blade is installed, arc sheetmetal 3 is positioned at the pump housing 1 inlet, at first play the effect that prevents to produce vortex in import, secondly the moving shear blade of utilizing impeller 4 entrance points of the fixed shear blade that is fixed on arc sheetmetal 3 on the pump housing 1 and high speed rotating to be constituted is come foreign material such as shearing fibre, play the effects such as medium of shearing and carrying foreign material such as fibre-bearing, shape and the position that can adjust arc sheetmetal 3 according to the shape and the position on sewage pump impeller inlet limit simultaneously is so that obtain better shear effect.
Claims (2)
1. the sewage pump with cutting device comprises the pump housing (1), and pump cover (2) is characterized in that being fixed with sheet metal (3) on the pump housing (1) inlet top, is provided with pump shaft (4) in the pump housing (1), and the impeller (5) and the motor (6) that link to each other with pump shaft (4).
2. a kind of sewage pump according to claim 1 with cutting device, it is characterized by: described sheet metal (3) became uneven, from with the attenuation gradually of the downward thickness of the pump housing (1) connecting place, a side that parallels with inlet side has shear blade, sees that from the pump housing (1) import sheet metal (3) shape is an arc.
