Description
Technical field
The present invention relates to the preposition cutter head of a kind of semi-open type Non-blinding pump, particularly a kind of pump cutter head with radial cuts and agitating function.
Background technology
At present, Non-blinding pump wide variety conventional on market, semi-open type Non-blinding pump is as one wherein, and when pumping sewage dirt medium, often there will be due to the larger blocking runner of particle, comparatively long fibre is wrapped on wheel hub; There are wearing and tearing in various degree in impeller, causes operational efficiency and by hydraulic performance decline, reduce reliability and the service life of pump.Therefore, at conveying bulky grain, still there is significant limitation during long fibre medium in common semi-open type Non-blinding pump.
Current domestic correlation technique and the report having occurred the Non-blinding pump about having preposition cutting or stirring cutter head.Referenced patent document " a kind of half-opened impeller is without blocking cutting pump " (application number: 201120437806.9), propose at the cutter disc of pump inlet place installation for shredding foreign material, effectively can cut and grind foreign material, this cutter sweep compact conformation, assembles more convenient.Its shortcoming is because import adds radial cuts device, reduces inlet-duct area, because which limit the flow of impeller inlet, makes the Power operation scope of this pump little.Referenced patent document " a kind of cut and the dredge pump stirred evenly " (application number: 201120006494.6), have employed and stir evenly dish in pump inlet place increase, cross flow table, rotating disc three parts, form cutting and stir evenly device, improve conveying sewage foreign material ability.Its shortcoming is that pump inlet place device is too many, is unfavorable for that sewage dirt circulates fast.
Summary of the invention
For solving the problem, the invention provides a kind of pump cutter head with radial cuts and agitating function, to overcome the deficiencies in the prior art.
The technical solution adopted for the present invention to solve the technical problems is: described pump cutter head comprises chopping disk 5 and cutter 6, and described chopping disk 5 is bolted on pump housing lower end; Half-opened impeller 4 is connected with pump shaft 2 by key, and described pump shaft 2 is also provided with cutter 6, and described cutter 6 are arranged on the front end of half-opened impeller 4; Described cutter 6 are axially fixed on pump shaft 2 by locking nut 7 with described half-opened impeller 4.
Further, described chopping disk 5 is circular, and its inner face is arranged at intervals with discontinuous trapezoidal groove, and the quantity of described trapezoidal groove is no less than 16.
Further, the degree of depth of described trapezoidal groove is 1/2nd of annular width.
Further, cutter 6 are arch-shaped; Described cutter excircle is provided with quadrangular cutter head 8; Described quadrangular cutter head 8 is no less than 4, and is evenly distributed on the excircle of described cutter 8.
Further, align with the excircle of described cutter 8 in the outer face of described quadrangular cutter head 8.
Further, described cutter 6 are also uniformly distributed 4 circular holes 9, described circular hole 9 radius is 1/8th of cutter 6 radius, and described center of circular hole is positioned at 1/2nd places of described cutting 8 cutter radius.
Further, the gap between described cutter 6 and chopping disk 5 is 1-2mm.
The invention has the beneficial effects as follows: the cutter of (1) this pump cutter head can coordinate chopping disk to grind dirt and cutting long fibre, strengthen the filth disposal ability of pump cutter head; (2) the arch bridge-type structure that cutter are special can realize the function stirring sewage dirt, improves sewage dirt treatment effect; (3) after circular hole being left by cutter, obviously increased by the discharge of sewage at impeller inlet place, improve water pump and to dispose of sewage the efficiency of dirt; (4) this pump is novel with cutter head structure, and manufacturing process is simple, obviously saves manufacturing cost.

Description of reference numerals is as follows: 1-submersible motor, 2-pump shaft, 3-grease chamber, 4-half-opened impeller, 5-chopping disk, 6-cutter, 7-locking nut, 8-quadrangular cutter head, 9-circular hole, 10-base.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail:
As shown in Figures 1 and 2, the pump cutter head with radial cuts and agitating function of the present embodiment comprises chopping disk 5 and cutter 6, and described chopping disk 5 is bolted on pump housing lower end; Half-opened impeller 4 is connected with pump shaft 2 by key, and described pump shaft 2 is also provided with cutter 6, and described cutter 6 are arranged on the front end of half-opened impeller 4; Described cutter 6 are axially fixed on pump shaft 2 by locking nut 7 with described half-opened impeller 4.
Described chopping disk 5 is circular, and its inner face is arranged at intervals with discontinuous trapezoidal groove, and the quantity of described trapezoidal groove is no less than 16, and the degree of depth of described trapezoidal groove is 1/2nd of annular width, and cutter 6 are arch-shaped; Described cutter excircle is provided with quadrangular cutter head 8; Described quadrangular cutter head 8 is no less than 4, and is evenly distributed on the excircle of described cutter 8, aligns with the excircle of described cutter 8 in the outer face of described quadrangular cutter head 8.
Described cutter 6 are also uniformly distributed 4 circular holes 9, described circular hole 9 radius is 1/8th of cutter 6 radius, and described center of circular hole is positioned at 1/2nd places of described cutting 8 cutter radius, and the gap between described cutter 6 and chopping disk 5 is 1-2mm.
Operation principle: when pump startup, motor 1 drives pump shaft 2 to rotate, and be fixed on the cutter 6 on axle and impeller 4 and then rotation, sewage dirt is entered by pump inlet, and first the arch bridge-type structure special due to cutter head can stir sewage dirt.By the effect of centrifugal force, large particle and long fibre are thrown to outer circumferential position, and under the mating reaction of chopping disk 5 and cutter 6, chopping disk 5 and cutter 6 grind bulky grain thing, cut off long fibre simultaneously.Chopping disk 5 and cutter 6 ensure that runner can not be blocked by sewage dirt, and sewage dirt can pass through impeller smoothly, enters spiral case, is discharged outside pump.
Conventional cutter head reaches stirring object by increasing agitating device, but its stirring capacity is very limited, and complex structure.The present invention by chopping disk is set to arch bridge structure, thus improves the stirring capacity of pump cutter head, and eliminates agitating device, has saved manufacturing cost.In prior art, sewage dirt can only pass through from the gap between cutter and chopping disk, and it is very limited to enter the less efficiency of pump that causes of the flow of sewage in impeller.The present invention opens circular hole 9 on cutter 6, a processed sewage dirt part can be made to enter impeller by circular hole, reach the effect increasing and become a mandarin.Added by the flow of impeller 4 import department like this, significantly improve water pump and to dispose of sewage the efficiency of dirt, reduce the manufacturing cost of chopping disk simultaneously.
Institute is noted that and the foregoing is only preferred embodiment of the present invention, not in order to limit the present invention.All any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
