Abstract
The utility model provides a kind of anti-blockage structure of sewage pump, be arranged at the water inlet of the pump housing, comprise the sleeve of water inlet, filter screen is provided with in described sleeve, also comprise the sewage draining exit be arranged between sleeve and water intake, the opposite side of described sleeve is provided with the flush pipe that the pump housing is stretched in one end, and the opposite side of flush pipe is provided with A stop valve.The utility model adopts flush pipe washing filter screen, removes the dirt on filter screen, and dirt is discharged by sewage draining exit; Adopt B stop valve, prevent the water taken out stains from flowing into the pump housing; Flush pipe one end to be stretched in the pump housing and is adopted scarf, coordinates one-way valve acting in conjunction, can effective washing filter screen, and prevents the dirt inflow flush pipe after removing.
Description
Technical field
The utility model belongs to energy-conserving and environment-protective field, especially relates to a kind of structure that can prevent sewage pump water intake from blocking.
Background technique
Sewage pump is a kind of pump of removal of contamination, mainly for delivery of the medium containing the solid particle such as fiber, paper scrap in urban sewage or liquid.There is impurity in medium due to the conveying of sewage pump, water intake easily blocks, and prior art mainly adopts and arranges filter screen in water inlet, tentatively filters fed sheet of a media, in case foreign material enter the normal work that the pump housing affects sewage pump.But the foreign material after filtering can stick on filter screen, cause filter screen to block, and then cause the water intake of sewage pump to block, make sewage pump normally to work.
Model utility content
Problem to be solved in the utility model is to provide a kind of structure that can prevent sewage pump water intake from blocking, and ensures that sewage pump normally works.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of anti-blockage structure of sewage pump, be arranged at the water inlet of the pump housing, comprise the sleeve of water inlet, filter screen is provided with in described sleeve, also comprise the sewage draining exit be arranged between sleeve and water intake, the opposite side of described sleeve is provided with the flush pipe that the pump housing is stretched in one end, and the opposite side of flush pipe is provided with A stop valve.
Further, the inserting end of described flush pipe is scarf, and scarf is towards filter screen.
Further, the flush pipe being positioned at described pump housing outside is provided with B stop valve.
The advantage that the utility model has and good effect are: the utility model adopts flush pipe washing filter screen, remove the dirt on filter screen, and dirt is discharged by sewage draining exit; Adopt B stop valve, prevent the water taken out stains from flowing into the pump housing; Flush pipe one end to be stretched in the pump housing and is adopted scarf, coordinates one-way valve acting in conjunction, can effective washing filter screen, and prevents the dirt inflow flush pipe after removing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the scheme of installation of filter screen in the utility model.
In figure:
1-water intake, 2-filter screen, 3-sewage draining exit, 4-flush pipe, 5-A stop valve, the 6-pump housing, 7-sleeve, 8-B stop valve.
Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
The anti-blockage structure of a kind of sewage pump as shown in Fig. 1 to 2, be arranged at water intake 1 place of the pump housing 6, comprise the sleeve 7 at water intake 1 place, filter screen 2 is provided with in described sleeve 7, also comprise the sewage draining exit 3 be arranged between sleeve 7 and water intake 1, the opposite side of described sleeve 7 is provided with the flush pipe 4 that the pump housing 6 is stretched in one end, and the opposite side of flush pipe 4 is provided with A stop valve 5, prevents the water taken out stains from flowing into the pump housing.
The inserting end of described flush pipe 4 is scarf, and scarf, can effective washing filter screen towards filter screen 2, and prevents the dirt after removing from flowing into flush pipe.
The flush pipe being positioned at described pump housing outside is provided with B stop valve 8.
Adopt technique scheme, sewage pump is when normally working, and B ends 8 valves and is in closed condition, and A stop valve 5 is in circulation status, and sewage draining exit 3 is in closed condition; When the filter screen 2 at water intake 1 place blocks, close A stop valve 5, open B stop valve 8 and sewage draining exit 3, current in flush pipe 4 enter the pump housing 6 washing filter screen 2, sewage after flushing flows out from sewage draining exit 3, after flushing, closes B stop valve and sewage draining exit 3, open A stop valve 5, sewage pump recovers normal work.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
