Abstract
The present invention discloses a kind of blowdown impeller of pump, and blade outboard edge is provided with bristle, and blade upstream face is provided with the cutting edge to blade tip edge by root of blade, and the cutting edge cutting edge is gradually increased away from upstream face distance by root of blade to blade tip.The impeller cleaning can be adhered to the jellies such as the silt of dredge pump inner wall while work, thread in cut-off sewage simultaneously, thread is cut into shorter wire body, sewage is followed to discharge, prevents from being stuck when being wound with thread in impeller and impeller axle.
Description
Technical field
The invention belongs to centrifuge pump technical field, specifically a kind of blowdown impeller of pump.
Background technology
Centrifugal pump is to be rotated using impeller and make water that centrifugal movement occur come work, and the impeller of rotation is driven in pump case
Water does high speed rotary motion, and water occurs centrifugal movement, is thrown toward impeller outer edge, and the runner through volute pump case flows into the pressure water of water pump
Pipeline.
When centrifugal pump is used for dredge pump in use, its medium composition is complicated, the jellies such as silt are usually included in sewage,
By being moved outward with water in the pump housing, the jellies such as silt can be adhered to inner walls and form one layer of silt layer, to make when serious
Into blocking；Also usually there are the threads such as silk thread in sewage, be easily wrapped on blade and impeller axle, impeller card can be made when serious
Extremely, dredge pump is damaged.
Invention content
Goal of the invention：The deficiency that the purpose of the present invention is be directed in current technology provides a kind of blowdown impeller of pump, described
Impeller cleaning can be adhered to the jellies such as the silt of dredge pump inner wall, while linear in cut-off sewage while work
Thread is cut into shorter wire body, sewage is followed to discharge by object, prevent in impeller and impeller axle when being wound with thread by
It is stuck.
Technical solution：To achieve the above object, the present invention provides a kind of blowdown impeller of pump, the setting of blade outboard edge
There is a bristle, blade upstream face is provided with the cutting edge to blade tip edge by root of blade, and the cutting edge cutting edge is away from meeting
Water surface distance is gradually increased by root of blade to blade tip.
Preferably, the bristle is evenly arranged in the range of entire leaf width.
Preferably, the bristle is steel wire.
Preferably, the cutting edge quantity is 1-6.
Advantageous effect：A kind of blowdown impeller of pump of the present invention, blade edge part is provided with steel wire bristle, steel
Wire brush hairbrush crosses dredge pump inner walls, can scrape the jellies such as the silt being adhered on inner wall, and by silt scraped etc.
Jelly is mixed discharges together in water body.
A kind of blowdown impeller of pump is additionally provided with cutting edge on upstream face, since blade pitgh is from by blade
Root gradually increases to blade tip, and therefore, cutting edge cutting edge is gradually increased away from upstream face distance by root of blade to blade tip
Greatly.In the impeller course of work, blade upstream face surface has larger linear velocity, when water body enters in dredge pump, blade
Substance on upstream face in cutting edge cutting edge and water body has larger speed difference, at this point, the meeting when thread touches cutting edge
Cut sword is cut off, and since flow is turbulence state in dredge pump, longer thread constantly collided by water body, ceaselessly with blade
Upper cutting edge contact, thread are constantly cut until sewage is followed to discharge as shorter wire body.
The blowdown impeller of pump cleaning can be adhered to the jellies such as the silt of dredge pump inner wall while work,
Thread, is cut into shorter wire body, sewage is followed to discharge, prevent impeller and impeller axle by thread in cut-off sewage simultaneously
On be stuck when being wound with thread.
Description of the drawings
Fig. 1, dredge pump blade wheel structure schematic diagram；
Reference numerals list：1st, blade, 2, bristle, 3, cutting edge.
Specific embodiment
With reference to the accompanying drawings and detailed description, the present invention is furture elucidated, it should be understood that following specific embodiments are only
For illustrating the present invention rather than limiting the scope of the invention.It should be noted that word " preceding " used in the following description,
" rear ", "left", "right", "up" and "down" refer to the direction in attached drawing, and word " interior " and " outer " refer respectively to direction or remote
Direction from particular elements geometric center.
A kind of blowdown impeller of pump as shown in Figure 1, including blade 1,1 outer ledge of blade is provided with bristle 2, bristle 2
For steel wire, it is evenly arranged in the range of entire leaf width.1 upstream face of blade is provided with 2 by 1 root of blade to 1 end edge of blade
The cutting edge 3 of edge, 3 cutting edge of cutting edge are gradually increased away from upstream face distance by 1 root of blade to 1 end of blade.
The technical means disclosed in the embodiments of the present invention is not limited only to the technological means disclosed in the above embodiment, further includes
By more than technical characteristic arbitrarily the formed technical solution of combination.
