Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further description:
Shown in Fig. 1 to 3; Cut-up type blow-down pump of the present invention comprises the pump housing and is arranged on the sewage transport device in the pump housing; One end of the pump housing is provided with intake end cover 1; Intake end cover 1 is provided with the stationary knife 11 and water intake 7 that has cutting edge, and an end of the nearly water intake 7 of sewage transport device is provided with the moving knife 10 that matches with stationary knife 11, is provided with water outlet 4 at the end away from water intake 7 of the pump housing.Form shredding mechanism by shearing the moving knife 10 that cooperates with stationary knife 11.The stationary knife 11 that has a cutting edge be positioned at intake end cover 1 on the end face of the pump housing 3 inner chambers; It is made up of a plurality of water intakes 7 and the axis hole 6 that are arranged on the intake end cover 1 at interval; Each water intake 7 is provided with around axis hole 6; Adjacent two water intakes 7 form bar shaped stationary knife 8 at interval, and water intake 7 forms annular stationary knife 9 with axis hole 6, and bar shaped stationary knife 8 intersects with annular stationary knife 9 forms stationary knife 11.Adopt said structure, can increase or reduce the opening area of water intake 7 as required, keep or increase the length of stationary knife 11, can on the basis of the inflow that improves water intake, keep the length of stationary knife, prevent that fiber from stopping up water intake.Adopt the stationary knife 11 of this kind shape to match with moving knife 10 better, help cutting off the long fibre that gets in the pump housing 3, under the scrolling of moving knife 10, can cut off the fiber tuft that accumulates in water intake 7 places effectively, prevent that long fibre from stopping up the pump housing.As shown in Figure 2, the cross section of bar shaped stationary knife 8 is type linearly, the cross section linearly during type the knife back 12 of best bar shaped stationary knife circumscribed with the cylindrical phase of annular stationary knife.As shown in Figure 4, bar shaped stationary knife cross section is preferably arc, when bar shaped stationary knife cross section is arc the knife back 12 of bar shaped stationary knife preferably with the cylindrical phase inscribe of annular stationary knife, the rotation direction of each bar shaped stationary knife is consistent.Adopt the bar shaped stationary knife of arc section can increase the length of stationary knife cutting edge, thereby improve the chopping ability of shredding mechanism.
Preferably water intake 7 is three; Each water intake 7 is the reaping hook capitiform; Be distributed on the surface of intake end cover 1 around axis hole 6, stationary knife 11 is formed to three equally distributed bar shaped stationary knifes 8 of the circumferential extension of intake end cover 1 by the annular stationary knife 9 that is positioned at the central position with from this annular stationary knife 9 like this.
The sewage transport device can be a screw axis, also can be impeller.In the preferred embodiments of the present invention, the sewage transport device is a screw axis.The moving knife 10 that has cutting edge is arranged on the spiral top 16 of screw axis 2, the axis normal setting of moving knife 10 and screw axis 2.
In preferred version of the present invention; Comprise that also motor coupling shaft sleeve 15, screw axis 2 are by motor driving; The other end at the pump housing 3 is provided with bearing (ball) cover 5, and intake end cover 1 is connected through bolt with 3 of the pump housings, and is same; Bearing (ball) cover 5 is connected through bolt with 3 of the pump housings; Be made up of spiral section and ladder shaft part through bearing (ball) cover 5 coaxial fixed connections by screw axis 2 with 15 in motor coupling shaft sleeve for the pump housing 3, and it is intersegmental and be arranged in the pump housing 3 that spiral section is arranged on spindle nose 14 and multidiameter shaft; The ladder shaft part of screw axis passes the pump housing 3 and motor coupling shaft sleeve 15 is fixedly connected with motor, by the bearing on the two end cap that is arranged on bearing (ball) cover 5 and motor coupling shaft sleeve 15 screw axis is supported.
Be provided with axis hole 6 at the center of intake end cover 1, the spindle nose 14 of screw axis 2 reaches outside the axis hole 6, and the spiral top 16 of screw axis 2 is arranged on spindle nose 14 places.
The spiral not-go-end blade 13 of screw axis 2 is oppositely arranged with the water outlet 4 that is arranged on the pump housing 3; Like this when sewage is risen to blade 13 places, spiral top by screw axis 2; The sewage water outlet 4 of can under action of inertia, directly gushing out; And can not receive the resistance of anti-flowing water; Thereby improve the efficient of draining, the name of mentioning in cut-up type blow-down pump of the present invention and the background technique be called " a kind of cut-up type blow-down pump ", the patent No. be ZL200910102094.2, cut-up type blow-down pump under equal conditions per hour water displacement improve about 5%-10%, the about 25%-30% of lift lifting.
In the preferred embodiment of sewage pump of the present invention, because shredding mechanism adopts the cooperating of structure of a plurality of water intakes and spirality stationary knife and moving knife, can effectively assemble and cut off long fibre, prevent at conveying sewage process medium-length fibre winding screw axle.
Filth-discharging effect is best when the helix angle of screw axis is 17 °.And the helix structure of screw axis have charging soon, not susceptible to plugging characteristics; So; Pollution discharge pump of the present invention can arrive water outlet with sewage transport fast; And the spiral not-go-end is oppositely arranged with water outlet, and sewage is taken advantage of a situation and is transported to outside the water outlet like this, is difficult for stopping up and the high characteristics of contaminant removal effectiveness so sewage pump of the present invention has.
The spiral section of screw axis 2 is installed in the pump housing 3 during use, and the ladder shaft part is connected with motor, and the pump housing 3 immerses in the cesspool, and motor is positioned at the liquid level top.When work, electrical power rotates, and drives screw axis 2 and rotates, and bottom liquid is pumped to water outlet 4; The moving knife of screw axis bottom and the stationary knife on the intake end cover have cutting edge, cut off contained long fibre material in the liquid, prevent to stop up.Under the atmospheric pressure effect, the pump housing 3 bottom liquids are constantly replenished, thereby realize continuous operation.
With the patent No. is that the patent of invention of ZL200910102094.2 is compared, cut-up type blow-down pump lift of the present invention and contaminant removal effectiveness more as shown in the table:
