Description
Technical Field
The utility model relates to a sewage collecting tank water pump opens and stops protection device.
Background
With the continuous development of society, environmental protection is more and more important, and all produced sewage must be collected and treated. The water pump is used for conveying, the water quantity is not uniform, and the water pump is started and stopped frequently. Because of the influence of the geographical position, as shown in fig. 2, the installation position of the water pump is higher than the water pool, so that when the water pump is stopped, sewage flows back to the sewage pool, a part of sewage enters the sewage pool, the front-stage water suction pipeline of the water pump enters air, when the water pump is started again, the air enters the water pump, and the water pump idles or cavitates, so that the service life of the water pump is shortened.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a sewage collecting tank water pump opens and stops protection device, can be when the water pump opens and stops, effectual water pump idle running or cavitation of avoiding, extension water pump life.
In order to solve the above problem, the to-be-solved technical scheme of the utility model is:
The utility model provides a sewage collection pond water pump opens and stops protection device, includes water pump and liquid level switch, and liquid level switch control water pump opens and stops, still includes the tank, tank upper end intercommunication blast pipe and leading water pipe, and the tank lower extreme passes through inlet tube intercommunication sewage collection pond lower extreme, and the tank lower extreme passes through drinking-water pipe intercommunication sewage treatment station, and the water pump is installed on the drinking-water pipe, and the tank internal water level is higher than the water pump water inlet, and one section drinking-water pipe of water pump intercommunication tank is less than the tank internal water level.
The water pumping pipe is communicated with a backflow tank, the lower end of the backflow tank is communicated with the water storage tank through a water return pipe, and one end of the water return pipe, which is positioned in the water storage tank, is provided with a ball float valve.
The technical effects of the utility model are that: the utility model discloses when can effectually avoid the water pump to start and stop, the air prevents water pump idle running or cavitation erosion in entering into the water pump, extension water pump life, on the other hand, when liquid level switch breaks down, can effectual protection water pump.
Drawings
The invention will be further explained with reference to the drawings:
Figure 1 is a schematic structural diagram of the present invention,
fig. 2 is the prior art mentioned above with reference to fig. 2.
in the figure: the sewage treatment system comprises a sewage collecting pool 1, a water storage tank 2, a water pump 3, a backflow tank 4, a ball float valve 5, a liquid level switch 6, a water inlet pipe 71, an exhaust pipe 72, a water diversion pipe 73, a water return pipe 74 and a water pumping pipe 75.
Detailed Description
To facilitate the understanding of the improvements made to the prior art by those skilled in the art, the following further description of the prior art is made with reference to the accompanying drawings:
As shown in fig. 2, at present, the sewage collecting tank 1 is excavated from the ground surface, the water pump 3 is installed on the ground surface, when sewage is pumped to the sewage treatment station in the sewage collecting tank 1, the water level switch 6 controls the water pump 3 to stop, a part of sewage in the water suction pipe communicating the water pump 3 with the sewage collecting tank 1 flows back to the sewage collecting tank 1, so that air enters the water suction pipe, when the water pump 3 is restarted, the air enters the water pump 3, the water pump 3 idles or cavitates, and the service life of the water pump 3 can be shortened by frequent idling or cavitation.
in order to solve the problem, the utility model provides a sewage collecting tank water pump opens and stops protection device, it includes water pump 3 and liquid level switch 6, liquid level switch 6 control water pump 3 opens and stops, still include water storage tank 2, water storage tank 2 all installs subaerial with water pump 3, 2 upper ends intercommunication blast pipe 72 of water storage tank and leading water pipe 73, 2 lower extremes of water storage tank pass through inlet tube 71 intercommunication sewage collecting tank 1 lower extreme, 2 lower extremes of water storage tank pass through drinking-water pipe 75 intercommunication sewage treatment station, water pump 3 is installed on drinking-water pipe 75, 2 interior water levels of water storage tank are higher than 3 water inlets of water pump, one section drinking-water pipe 75 of 3 intercommunication water storage tank 2 of water pump is less than the 2 interior water levels of water storage tank.
When first use, can open the valve on blast pipe 72 and the leading water pipe 73, pour into water storage tank 2 by leading water pipe 73 with the running water, then close the valve on blast pipe 72 and the leading water pipe 73, after water pump 3 starts, with water pumping to the sewage treatment station through water storage tank 2, when water pump 3 shut down, water in the water storage tank 2 stops in one section drinking-water pipe 75 of water pump 3 intercommunication water storage tank 2 to when preventing that water pump 3 from starting next time, the air enters into in the water pump 3.
When level switch 6 damages or is malfunctioning, water pump 3 continues the operation after managing to find time sewage collecting pit 1 and water storage tank 2 in sewage, and the long-time idle of water pump 3 can lead to water pump 3 to burn out, takes place in order to avoid this kind of things, the utility model discloses make following further improvement: the water pumping pipe 75 is communicated with the return tank 4, the lower end of the return tank 4 is communicated with the water storage tank 2 through a return pipe 74, and one end of the return pipe 74, which is positioned in the water storage tank 2, is provided with a ball float valve 5. When sewage in the water storage tank 2 is pumped to open the ball float valve 5, water pumped into the backflow tank 4 by the water pump 3 is returned to the water storage tank 2 through the backflow water pipe 74 to form circulation, and idling of the water pump 3 is effectively avoided.
