Background technique
Sewage pump, is widely used in the industries such as municipal administration, environmental protection, sewage treatment, light industry, chemical industry, mine, oil, water conservancy, metallurgy, is one of the big power consumer of relevant industries and key equipment.At present; the sewage pump that is used for pumping sewage is due to cutting device not being set; using sewage pump can be got lodged in the liquid entering hole of sewage pump and stop up liquid entering hole by solids such as some branches, weeds in pumping the process of sewage; even be stuck in and on water wheels, affect electric machine rotation; when serious, cause motor to burn out, successfully pump after sewage must be shut down and clean out obstruction, then row starts sewage pump extraction sewage; lose time, make again to clear up the operating difficulties of dirt.
Chinese patent CN202012481U discloses a kind of sewage pump with cutting device, and the disclosure patent is set up a reamer at liquid entering hole place, and first every solid sundries that enters liquid entering hole can cut through reamer, and then enters the pump housing and get rid of.The disclosure patented technology has played anticlogging effect to a certain extent really, but also can find simultaneously, because the current of liquid entering hole are for revolving nest current, lighter foreign material can be revolving fast rotational in nest current, its rotational speed equates even to exceed reamer rotating speed with reamer rotating speed, thereby now reamer cannot cut to these foreign material, once such foreign material gathering is more, just likely there is the phenomenon that gets stuck in reamer.
Model utility content
The technical problems to be solved in the utility model be to provide a kind of simple in structure, dispose of sewage smooth and easyly, can effectively avoid sewage foreign material to stop up the sewage pump with cutting device of water pump liquid entering hole.
A kind of sewage pump with cutting device of the utility model, comprising: the pump housing, motor; The described pump housing comprises upper shaft hole, impeller, inlet opening, and wherein impeller is arranged at the inner chamber of the pump housing; Described machine shaft passes pump housing upper shaft hole, impeller shaft hole from top to bottom successively, and finally stretches out inlet opening; The upper shaft hole of described machine shaft and the pump housing forms revolute pair, and described machine shaft is fixedly connected with impeller; Also be provided with a cutting disk in pump housing liquid entering hole below, described cutting disk is provided with an axis hole and multiple feed liquor through hole, and the lower surface of described cutting disk is also provided with multiple curved slots; Described cutting disk is fixedly connected with the pump housing, and described cutting disk and machine shaft form revolute pair; Also be provided with a reamer in the below of cutting disk, described reamer is fixedly connected with machine shaft.
A kind of sewage pump with cutting device of the utility model, wherein said curved slot starts from axis hole cutting disk edge finally.
A kind of sewage pump with cutting device of the utility model, wherein said reamer has three cutting blades, and three cutting blades are mutually 120 °.
A kind of sewage pump with cutting device of the utility model, wherein said cutting blade both sides are equipped with cutting edge.
The sewage pump difference from prior art of the utility model band cutting device is that the sewage pump of the utility model band cutting device set up curved slot at the lower surface of cutting disk, when foreign material curved slot in the time that cutting disk lower surface rotates can form certain obstruction to it, even can be by stuck foreign material in curved slot, now the rotational velocity of foreign material will be lower than reamer rotating speed, and then reamer can successfully effectively cut foreign material, thereby can effectively avoid sewage foreign material to stop up water pump liquid entering hole, ensure the smooth and easy discharge of sewage.
In the utility model, the curved slot of the lower surface of cutting disk starts from cutting disk axis hole cutting disk edge finally, that is to say and be all provided with curved slot as long as the region of reamer process, be exactly that reamer does not have dead angle to the processing of foreign material furtherly, thereby it process foreign material successful.
Below in conjunction with accompanying drawing, the sewage pump of the utility model band cutting device is described further.
Brief description of the drawings
Fig. 1 is the structural representation of the sewage pump of the utility model band cutting device;
Fig. 2 is reamer and cutting disk combination worm's eye view in the sewage pump of the utility model band cutting device.
Embodiment
As shown in Figure 1 and Figure 2, a kind of sewage pump with cutting device of the utility model, comprising: the pump housing 2, motor 1.The pump housing 2 comprises upper shaft hole 21, impeller 3, inlet opening 22, and wherein impeller 3 is arranged at the inner chamber of the pump housing 2.The upper shaft hole 21 of the pump housing 2, the axis hole of impeller 3 are passed in the rotating shaft 11 of motor 1 from top to bottom successively, and finally stretch out inlet opening 22.The rotating shaft 11 of motor 1 is axially fixed at upper shaft hole 21 places of the pump housing 2 by bearing pair, the rotating shaft 11 of motor 1 is fixedly connected with impeller 3.Also be provided with a cutting disk 4 in the below of liquid entering hole 22, cutting disk is provided with an axis hole and multiple feed liquor through hole 41, and the lower surface of cutting disk 4 is also provided with multiple curved slots 42, and curved slot 42 starts from the axis hole edge of cutting disk 4 finally of cutting disk 4.Cutting disk 4 is fixedly connected with the pump housing 2, and the rotating shaft 11 of motor 1 is axially fixed at the axis hole place of cutting disk 4 simultaneously by bearing pair; Also be provided with a reamer 5 in the below of cutting disk 4, reamer 5 has 51, three cutting blades of three cutting blades to be mutually 120 ° of angles, and the both sides of cutting blade 51 are equipped with cutting edge.Reamer 5 is fixedly connected with the rotating shaft 11 of motor 1.
