Abstract
The utility model discloses a can be long-term with dirty pump impeller stealthily of fibre thing shredding contains an impeller shaft hole, an impeller wheel hub and an impeller apron the circumference of impeller apron on distribute and have a plurality of blades, the end of blade be equipped with an impeller respectively and tear the blade. The tearing cutting edge of the impeller is a sharp-edged tearing cutting edge. The utility model discloses a can be long-term with the stealthily dirty pump impeller of fibre thing shredding has following advantage: because the tearing edge of the impeller adopts the sharp-edged tearing edge, the impeller tearing edge is different from the existing right-angled edge, has the effect of thorough tearing, and can not cause the pump to be blocked. The impeller is made of high-chromium steel through heating treatment, so that the tearing cutting edge is guaranteed to have better abrasion resistance, and the effective service life of the pump is greatly prolonged.
Description
Technical Field
The utility model relates to a sewage conveying device, in particular to a submersible sewage pump impeller which can long-term shred fiber objects.
Background
The centralized transportation and treatment of production, domestic sewage, rainwater and the like become important components of modern civilized life. To construct a green and beautiful home, the sewage must be well treated.
The existing tearing type pump for conveying fiber impurities in sewage has the defects of poor fiber matter shredding effect, frequent blockage of the pump, short effective service life of the pump and the like due to parts and structures.
SUMMERY OF THE UTILITY MODEL
The utility model discloses solve the technical problem that prior art exists to a dirty pump impeller stealthily that can be long-term with the fibre thing shredding is provided.
The above technical problem of the present invention can be solved by the following technical solutions:
the submersible sewage pump impeller capable of shredding fiber for a long time is characterized by comprising an impeller shaft hole, an impeller hub and an impeller cover plate, wherein a plurality of blades are distributed on the periphery of the impeller cover plate, and the tail ends of the blades are respectively provided with an impeller tearing cutting edge.
As a preferred embodiment of the present invention, the tearing edge of the impeller is a sharp edge.
As a better embodiment of the utility model, the submersible sewage pump impeller which can long-term shred the fiber is made of high chrome steel through heating treatment.
The utility model discloses a can be long-term with the stealthily dirty pump impeller of fibre thing shredding has following advantage: because the tearing edge of the impeller adopts the sharp-edged tearing edge, the impeller tearing edge is different from the existing right-angled edge, has the effect of thorough tearing, and can not cause the pump to be blocked. The impeller is made of high-chromium steel through heating treatment, so that the tearing cutting edge is guaranteed to have better abrasion resistance, and the effective service life of the pump is greatly prolonged.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
FIG. 1 is a schematic structural view of a submersible sewage pump impeller capable of shredding fibrous materials for a long term;
FIG. 2 is a schematic view of the impeller of FIG. 1, from another perspective;
fig. 3 is a schematic view of the use of the impeller of fig. 1.
Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention can be more clearly and clearly defined.
As shown in fig. 1 and 2, the submersible sewage pump impeller capable of shredding fibrous materials for a long term comprises an impeller shaft hole 1, an impeller hub 2 and an impeller cover plate 3, wherein a plurality of blades 5 are distributed on the circumference of the impeller cover plate 3, and the tail ends of the blades 5 are respectively provided with an impeller tearing cutting edge 4.
The impeller tearing edge 4 is a sharp-edged tearing edge.
The submersible sewage pump impeller capable of long-term shredding of fiber materials is made of high-chromium steel through heating treatment.
The method of using the submersible sewage pump impeller to permanently shred fibrous material is described below.
As shown in fig. 3, the motor shaft penetrates into the impeller shaft hole 1 to drive the impeller to rotate at high speed. The impeller tearing cutting edge 4 positioned at the end face of the blade 5 and other parts on the pump, including the pump cover 9 and the outer tearing cutter head 10 form a scissor-like tearing cut. The fibrous impurities in the medium conveyed by the pump are shredded when they flow through the scissors cuts as water is sucked in through the pump inlet 11 and are then conveyed out through the pump outlet 12 along with the water.
Because the tearing edge 4 of the impeller adopts a sharp-edged tearing edge, the impeller is different from the existing right-angled edge, has the effect of thorough tearing, and can not cause the pump to be blocked. The impeller is made of high-chromium steel through heating treatment, so that the tearing cutting edge 4 is guaranteed to have better wear resistance, and the effective service life of the pump is greatly prolonged.
Without being limited thereto, any changes or substitutions which are not thought of through creative efforts should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
