The utility model provides a kind of cutting type submersible axial flow pump, comprise diffuser, intake tunnel, impeller hub, blade, the inner side of intake tunnel is provided with several quiet cutting blades, the below of impeller hub connects impeller water guide post, the outside of impeller water guide post is provided with fixed pedestal, fixed pedestal is fixedly connected with rotary cutting blade, quiet cutting blade and rotary cutting blade are interlocked and are extended, the below of intake tunnel connects cutting disk, two fixed blades are arranged with in cutting disk, the below of cutting disk is connected with filter screen, fixed by fixing bolt between diffuser and intake tunnel.The beneficial effects of the utility model are when submersible axial flow pump carries out work, successively by filter screen, cutting disk, for the twister chopping in medium, rotate cooperatively interacting between driven rotary cutting blade and quiet cutting blade under effect eventually through impeller water guide post to act on, ensure that the effect of axial-flow pump inner member, extend the working life of equipment.

Description

A kind of cutting type submersible axial flow pump
Technical field
The utility model belongs to axial-flow pump technical field, especially relates to a kind of cutting type submersible axial flow pump.
Background technique
Traditional submersible axial flow pump is by diffuser, blade, wheel hub, water guide cone, the parts compositions such as water-inlet horn, traditional submersible axial flow pump leans on the blade of rotary blade to the active force that liquid produces, liquid to be carried in the axial direction, when submersible axial flow pump carries out work, wheel hub is by rotating thus driving blade movement to rotate, water is flowed out along gate vane channel, present axial-flow pump is also applied in sewage work, a lot of dirt is there is in sewage, wherein have a certain amount of twister in dirt, when axial-flow pump carries out work, twister can be wrapped on blade, cause blade can not carry out the normal operation of normal Effect of Rotation equipment, the element of damage axial-flow pump inside, shorten its working life, improve the cost in manufacturing operation.
Model utility content
The purpose of this utility model be to provide a kind of structure simple, simple to operate, pump medium and contain twister, cutting type submersible axial flow pump that manufacturing efficiency is high.
The technical solution of the utility model is: a kind of cutting type submersible axial flow pump, comprise diffuser, intake tunnel, impeller hub, blade, the inner side of described intake tunnel is provided with several quiet cutting blades, the below of described impeller hub connects impeller water guide post, the outside of described impeller water guide post is provided with fixed pedestal, described fixed pedestal is fixedly connected with rotary cutting blade, described quiet cutting blade and rotary cutting blade are interlocked and are extended, the below of described intake tunnel connects cutting disk, two fixed blades are arranged with in described cutting disk, the below of described cutting disk is connected with filter screen, fixed by fixing bolt between described diffuser and intake tunnel.
Further, the outside of described quiet cutting blade is provided with several slitting wheel portions.
Further, the cutting edge angle of described fixed blade and rotary cutting blade is acute angle.
Further, described filter screen adopts Stainless Steel Wire to make.
The advantage that the utility model has and good effect are: owing to adopting technique scheme, when submersible axial flow pump carries out work, first filtered for the first time by filter screen, the twister damaged easily causing submersible axial flow pump filters out a part, shred for the twister in medium through cutting disk again, rotate cooperatively interacting between driven rotary cutting blade and quiet cutting blade under effect eventually through impeller water guide post to act on, fast and effectively the twister in medium is shredded again, too much twister is avoided to be wrapped on blade, affect the normal rotation of blade, ensure that the effect of axial-flow pump inner member, extend the working life of equipment.

Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
As shown in Figure 1, a kind of cutting type submersible axial flow pump of the utility model, comprise diffuser 1, intake tunnel 2, impeller hub 3, blade 4, the inner side of described intake tunnel 2 is provided with several quiet cutting blades 5, the below of described impeller hub 3 connects impeller water guide post 6, the outside of described impeller water guide post 6 is provided with fixed pedestal 7, described fixed pedestal 7 is fixedly connected with rotary cutting blade 8, described quiet cutting blade 5 extends with rotary cutting blade 8 is staggered, the below of described intake tunnel 2 connects cutting disk 9, two fixed blades 10 are arranged with in described cutting disk 9, the below of described cutting disk 9 is connected with filter screen 11, 12 are fixed by fixing bolt between described diffuser 1 and intake tunnel 2.
The outside of described quiet cutting blade 5 is provided with several slitting wheel portions 13.
Described fixed blade 10 is acute angle with the cutting edge angle of rotary cutting blade 8.
Described filter screen 11 adopts Stainless Steel Wire to make.
The working procedure of this example: when submersible axial flow pump carries out work, first filtered for the first time by filter screen 11, the twister had in medium is filtered out a part, chopping work is carried out for the twister in medium afterwards through cutting disk 9, act on eventually through cooperatively interacting between driven rotary cutting blade 8 and quiet cutting blade 5 under the turning effort of impeller water guide post 6, effectively rapidly the twister in medium is shredded again, too much twister is avoided to be wrapped on blade 4, affect the normal rotation of blade 4, the maximized effect having given play to cutting type submersible axial flow pump, by the shredding mechanism of multilayer by medium with twister chopping, twister is avoided to enter into the blade of axial-flow pump, affect the normal work of blade, thus ensure that the effect of axial-flow pump inner member, extend the working life of equipment.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
