Abstract
The utility model provides an automatic filtering and anti-blocking submerged pump. The automatic filtering and anti-blocking submerged pump comprises a pump shell, wherein an impeller component is installed inside the pump shell, a water inlet and a water outlet are formed in the pump shell respectively; the automatic filtering and anti-blocking submerged pump is characterized in that a trumpet hole is connected at the water inlet, and a filter screen is installed at the opening of the trumpet hole. As the filter screen is arranged to enable sewage water to enter into a pump body after most impurities are filtered away by the filter screen, long fiber impurities in water are prevented from entering into a pump directly to block impellers, normal work of the submerged pump is ensured, and solid materials accumulated in a water pool can be discharged periodically through a residue discharge pump.
Description
technical field
The utility model relates to the water pump field, particularly a kind of automatic fitration anti-blocking submersible pump.
background technique
A large amount of existence of large scale foreign material in native sewage water, such as north pocket, leaf etc., cause pump easily to block in lifting process, once the blocked meeting of pump makes the pump cisco unity malfunction, motor damage even, thus cause blowdown not smooth.Bring serious impact to urban life and environmental protection.
For fear of the obstruction of sewage submersible pump occurs in the process promoted, Chinese patent 201220693628.0 discloses a kind of novel without stopping up cutter formula impeller pollution discharge pump, be provided with cutter formula pump cover on the pump housing, be provided with cutter formula impeller on bearing, described cutter formula impeller is to be provided with the lobus sinister face edge of a knife and the lobus dexter face edge of a knife, when crude fiber enters, the lobus sinister face edge of a knife and the lobus dexter face edge of a knife and cutter formula pump cover form cutting, make water pump without obstruction.This patent diminishes it by the cutting long fibre, thereby avoids the obstruction that pump is caused, and cutting effect is poor in actual applications, and the stronger more difficult quilts of article of toughness such as some plastic bags shred, and the anti-blocking effect is undesirable.
the model utility content
The purpose of this utility model is that the problem for above-mentioned existence provides a kind of automatic fitration anti-blocking submersible pump, can avoid the solid matter of coarsegrain to enter submersible pump, thereby avoid the obstruction of submersible pump.
Above-mentioned purpose realizes by following technological scheme:
Automatic fitration anti-blocking submersible pump, comprise pump case, and impeller assembly is installed in described pump case the inside, is respectively arranged with water intake and water outlet on described pump case, and described water inlet connects horn mouth, and described bell-mouthed opening is installed filter screen.
Described automatic fitration anti-blocking submersible pump, described impeller assembly comprises the impeller motor, described impeller connects water pump spindle with the pto＝power take-off of motor, on described water pump spindle, impeller is installed.
Described automatic fitration anti-blocking submersible pump, the relative aperture of described bell-mouthed heavy caliber end and small-caliber end is (5-10): 1, the 6-8 that described bell-mouthed length is water intake is doubly.
Beneficial effect:
1. the utility model arranges filter screen, allow sewage enter again the pump housing after filter screen filters out most impurity, avoid the long fibre impurity in water directly to enter the situation generation that causes impeller to block after the pump housing, ensure the normal operation of submersible pump, the solid matter be accumulated in pond can regularly be discharged by deslagging pump, the utility model is provided with horn mouth, filter screen is arranged on horn mouth, because filter screen is arranged on bell-mouthed heavy caliber end, under the suction function of impeller, water inlet produces the negative pressure of handing over, by bell-mouthed heavy caliber, pressure is reduced, avoiding filter screen to be directly installed on the situation that causes long fibre to cause filter screen to stop up as plastic bag etc. is adsorbed on filter screen in water inlet occurs.
2. further, be adsorbed on filtration up for fear of impurity under the effect of negative pressure, the relative aperture of the utility model described bell-mouthed heavy caliber end of design and small-caliber end is (5-10): 1, the 6-8 that described bell-mouthed length is water intake doubly, can effectively avoid this phenomenon to occur.
the accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, pump case, 2, water intake, 3, water outlet; 4, horn mouth; 5, filter screen; 6, impeller motor; 7, water pump spindle; 8, impeller.
embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.Should understand following embodiment and only for the utility model is described, be not used in restriction scope of the present utility model.
Embodiment 1:
As shown in Figure 1, automatic fitration anti-blocking submersible pump of the present utility model, comprise pump case 1, impeller assembly is installed in described pump case the inside, be respectively arranged with water intake 2 and water outlet 3 on described pump case, described water inlet connects horn mouth 4, and described bell-mouthed opening is installed filter screen 5.
Embodiment 2:
The described automatic fitration anti-blocking of embodiment 1 submersible pump, described impeller assembly comprises motor 6 for impeller, described impeller connects water pump spindle 7 with the pto＝power take-off of motor, and impeller 8 is installed on described water pump spindle.
Embodiment 3:
The disclosed technological means of the utility model scheme is not limited only to the disclosed technological means of above-mentioned technological means, also comprises by above technical characteristics and is equal to the technological scheme that replacement forms.Unaccomplished matter of the present utility model, belong to those skilled in the art's common practise.
Claims (3)
