Description
Technical field
The utility model belongs to fluid machinery technical field, is related to a kind of cutting pump, in particular to a kind of cutting pump pump head.
Background technique
Cutting pump belongs to one kind of pollution discharge type water pump, and relative to conventional water pump, cutting pump is installed inside it in structure
Have the impeller of one group of belt cutter mouth, by high-speed rotating impeller realize cutting effect, can light shredded fibre, excrement, tree
The sundries such as branch, and the typically more severe solid sundries of the working environment of cutting pump are various, therefore to the more demanding of the pump housing, mesh
The edge of a knife that preceding conventional cutting pump mainly passes through vane edge is cut, and cutting effect is poor, and knife after long-term use
Mouth is easy to appear abrasion rust, and performance further declines, the short problem of service life.
Summary of the invention
The purpose of this utility model is to provide a kind of good cutting effect simultaneously for the above-mentioned problems in the prior art
And the cutting pump pump head that the service life is longer.
The purpose of this utility model can be realized by the following technical scheme: a kind of cutting pump pump head, including spiral case, water inlet
The motor shaft connection of section, ring flange and impeller, the impeller and cutting pump is located in spiral case, the water inlet joint and ring flange
It is respectively fixedly connected by bolt in the two sides up and down of spiral case, which is characterized in that the upper surface of the water inlet joint upwardly extends to form one
Enclose installation step, be fixed with chopping disk on the installation step, the chopping disk be arranged in below impeller on impeller
Blade cooperates and is located in spiral case, and the upper surface of chopping disk makes chopping disk and leaf from outer be uniformly recessed gradually downward toward center
The gap of piece bottom becomes larger, and goes back circumferential on the chopping disk and uniformly offers several cutting grooves, the blade
Bottom is provided with the edge of a knife of integral type outward, and the edge of blade is provided with notch.
The technical effect of this cutting pump pump head are as follows: impeller drives high speed rotation by pumping intracorporal motor, by liquid from into
It being inhaled at water section and is thrown away to spiral case inner wall, the intracorporal impurity of liquid is also inhaled into simultaneously, when impurity passes through chopping disk, due to
Gap between chopping disk and wheel bottom is gradually closed to outer ring, and the bottom of impeller blade is knife edge type structure, therefore miscellaneous
Matter will be chopped into and throw away again, further, since some impurity quality are harder, in order to preferably realize cutting effect, cut
Several cutting grooves are opened up on disk, make impurity be easier to be cut by the edge of a knife the case where being blocked by cutting groove, and work as cutting pump quilt
In the case that impurity blocks, impeller is reversely rotated by the way that notch is arranged at the edge of blade, can be cut off and be taken out with impurity, increased
The practicability of cutting pump.
It is located at water inlet in a kind of above-mentioned cutting pump pump head, on the chopping disk and is circumferentially provided with several one
The cutting teeth of formula.
In a kind of above-mentioned cutting pump pump head, several circle bar shaped teeth are provided on the inner wall of the spiral case.
In a kind of above-mentioned cutting pump pump head, the upper end of the spiral case offers seal groove, and by with ring flange
Cooperation installs sealing ring in seal groove and realizes sealing effect.
Compared with prior art, this cutting pump pump head has the advantage that 1, is realized by the cooperation of impeller and chopping disk
Cutting, cutting effect is more preferable and the edge of a knife is not easy to wear；2, the impurity harder to quality can more preferably be cut, and make cutting pump not
Easily it is stuck；3, the design of notch further increases the practicability of cutting pump.
Detailed description of the invention
Fig. 1 is the Structure explosion diagram of this cutting pump pump head.
In figure, 1, spiral case；2, water inlet joint；3, ring flange；4, impeller；4a, blade；4b, the edge of a knife；4c, notch；5, erecting bed
Rank；6, chopping disk；6a, cutting groove；6b, cutting teeth；7, bar shaped tooth；8, seal groove.
Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1, this cutting pump pump head, including spiral case 1, water inlet joint 2, ring flange 3 and impeller 4, impeller 4 and cutting pump
Motor shaft connection be located in spiral case 1, water inlet joint 2 and ring flange 3 are respectively fixedly connected by bolt in the two sides up and down of spiral case 1, into
The upper surface of water section 2 upwardly extends to form a circle installation step 5, and chopping disk 6 is fixed on installation step 5, and the setting of chopping disk 6 exists
The lower section of impeller 4 cooperates and is located in spiral case 1 with the blade 4a on impeller 4, the upper surface of chopping disk 6 from it is outer toward center gradually
