Abstract
The utility model relates to a structure that is position at the place of the water inlet in sewage submarine pump and comprises a base (2), a water inlet (21), an impeller (1), an impeller axle (3) as well as a dasher (5); wherein, the dasher (5) is fixedly positioned in the base (2) and under the water inlet (21). The utility model has the advantages of: due to the addition of dasher at the water inlet, the block of water inlet caused by impurities is prevented when running the pump to achieve better effect of pollution discharge and sullage-removing.
Description
Technical field
The utility model relates to a kind of proof submersible sand discharging pump, relates in particular to water inlet structure in this proof submersible sand discharging pump.Background technique
Proof submersible sand discharging pump and general clean waterpump different be in: the blade of impeller is few, is generally two blade impeller, and runner is wide simultaneously, is convenient to carry the sewage that has fiber or other suspended impurity.In addition, the pump bigger for bore exists, and offers inspection, clean-out hatch on the shell of the pump housing, is convenient to remove after parking the dirty impurity of pump case inside.At present, existing proof submersible sand discharging pump, its range of flow are 1 ~ 2000m
3/ h, range of lift are 2 ~ 50m water column, and power range is 1 ~ 160kW.
As seen from Figure 1: the flow direction such as the arrow of existing proof submersible sand discharging pump medium are indicated, enter impeller 1 through the water intake 21 on the base 2, pass through outside the pump housing 4 excavationg pumps through the work done of impeller shaft 3 impeller more again.
But the problem that such structure exists is: contain impurity such as a large amount of particles or suspended matter in sending medium; pump is not in operation; impurity can slowly precipitate; stop up the water intake of base 2; wait for when start operation next time; water inlet can be not smooth, thereby the normal operation of influence can not be played good blowdown or remove the effect of becoming silted up.
Summary of the invention
The utility model technical issues that need to address have provided water inlet structure in a kind of proof submersible sand discharging pump, are intended to solve above-mentioned defective.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: base, water intake, impeller, impeller shaft; Also comprise a stirring apparatus; Described stirring apparatus fixed in position is in base, under the water intake.
Compared with prior art, the beneficial effects of the utility model are: owing to added stirring apparatus at water intake, when primer pump turned round, impurity can not stop up water intake, played good blowdown or removed the effect of becoming silted up.
Description of drawings
Fig. 1 is a prior art proof submersible sand discharging pump structural drawing;
Fig. 2 is a structural drawing of the present utility model;
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As seen from Figure 2: the utility model comprises: base 2, water intake 21, impeller 1, impeller shaft 3; Also comprise a stirring apparatus 5; Described stirring apparatus 5 fixed in position in base 2, water intake 21 times;
Described stirring apparatus 5 comprises that 51, one of stirring wheels stir wheel shaft 52; Stirring wheel shaft 52 fuses with impeller shaft 3;
Between stirring apparatus 5 and water intake 21, can also comprise the baffle plate 6 of fixed in position on base 2.
The utility model extends impeller shaft, in the bottom stirring wheel has been installed simultaneously.Stirring wheel rotates with the axis, and produces extremely strong mixing power, and the sludge around the base is stirred into suspended matter, discharges in the suction pump, improves anti-blocking, pollution discharge capability, disposablely finishes stirring, blowdown, removes silt, has saved operating cost greatly.The unlikely water inlet that has influence on pump of stirring action for stirring wheel is formed simultaneously.The utility model also improves base, above stirring wheel, increased by a plate washer, thereby the base water inlet is divided into two-part up and down, medium enters impeller by the water inlet on base top, pass through the work done of impeller again, discharge by the pump housing, stirring and water inlet are independent of each other, thereby improved the working efficiency of pump.
Claims (3)
1. water inlet structure in the proof submersible sand discharging pump comprises: base (2), water intake (21), impeller (1), impeller shaft (3); It is characterized in that: also comprise a stirring apparatus (5); Described stirring apparatus (5) fixed in position is in base (2), under the water intake (21).
2. water inlet structure in the proof submersible sand discharging pump according to claim 1 is characterized in that: described stirring apparatus (5) comprises a stirring wheel (51), and one is stirred wheel shaft (52); Stirring wheel shaft (52) fuses with impeller shaft (3).
3. water inlet structure in the proof submersible sand discharging pump according to claim 1 and 2 is characterized in that: can also comprise the baffle plate (6) of fixed in position on base (2) between stirring apparatus (5) and water intake (21).
