Description
Technical Field
The utility model relates to a sewage treatment field especially relates to a centrifugal pump for sewage treatment.
Background
A centrifugal water pump for sewage treatment is because need frequently to start and shut down, all need add the diversion earlier and fill the pump body when starting up at every turn, just can normally work, and this has not only caused the wasting of resources, has increased the load for the device simultaneously, has increased work burden for the workman, has increaseed work load.
SUMMERY OF THE UTILITY MODEL
The utility model discloses to the above-mentioned not enough that prior art exists, provide a centrifugal pump for sewage treatment that does not need the water injection.
The utility model aims at realizing through the following technical scheme:
the utility model provides a centrifugal pump for sewage treatment, exchanges interface, cistern, piston slide, hollow buoyancy ball, cistern delivery port under the pump body, centrifugal impeller, pump body delivery port, cistern, the pump body is inside to have centrifugal impeller, and centrifugal impeller rotates on the pump body, and pump body circumference has pump body delivery port, and the lower part of cistern right side has and exchanges interface under the cistern, and exchange interface under pump body delivery port upper portion connection cistern, the upper right side of cistern has the cistern delivery port, and the check valve is connected to the cistern delivery port, and the inside piston slide that has of cistern, hollow buoyancy ball of piston slide internal connection, hollow buoyancy ball slide in the piston slide.
The piston is connected to hollow buoyancy ball upside, and the piston slides along with hollow buoyancy ball, and cistern upper portion has the scavenge port, and the scavenge port suits with piston upper portion external diameter, and the piston slides in the scavenge port, and the pump body rear side has hollow chamber, and the pump body passes through hollow chamber connector intercommunication with hollow chamber, and hollow chamber rear side has the pump body water inlet, and sea valve is connected to pump body water inlet rear side.
Has the advantages that:
the sea bottom valve is opened, water enters the pump body from the water inlet of the pump body under the action of centrifugal force and then enters the reservoir upwards, the water overflows the piston slide way, the piston slide way upwards supports the piston along with the buoyancy of the water until the scavenging port is sealed, the water continues to flow out along the water outlet of the reservoir, the sea bottom valve is closed, the centrifugal pump is closed, the water outlet of the reservoir forms negative pressure due to the one-way conduction effect of the one-way valve, the piston and the scavenging port form negative pressure in the reservoir under the action of liquid seal and friction force, so that liquid can not flow back, the sea bottom valve is closed, the water is always stored in the pump, the sea bottom valve is opened and the piston is pressed when the sea bottom valve is used again, and the trouble of adding water manually can be avoided.

Detailed Description
The invention is explained in more detail below with reference to the figures and examples:
the utility model provides a centrifugal pump for sewage treatment, includes exchange interface 04, cistern 05, piston slide 06, hollow buoyancy ball 07, cistern under the pump body 01, centrifugal impeller 02, pump body delivery port 03, the cistern, centrifugal impeller 02 has inside the pump body 01, and centrifugal impeller 02 rotates on the pump body 01, and pump body 01 circumference has pump body delivery port 03, and the lower right part of cistern 05 has exchange interface 04 under the cistern, and exchange interface 04 under the connection cistern on pump body delivery port 03 upper portion, and the upper right side of cistern 05 has cistern delivery port 08, and cistern delivery port 08 connects check valve 09, and cistern 05 is inside to have piston slide 06, and piston slide 06 internal connection hollow buoyancy ball 07, hollow buoyancy ball 07 slides in piston slide 06.
The upper side of the hollow buoyancy ball 07 is connected with a piston 10, the piston 10 slides along with the hollow buoyancy ball 07, the upper part of the reservoir 05 is provided with a ventilation port 11, the ventilation port 11 is matched with the outer diameter of the upper part of the piston 10, the piston 10 slides in the ventilation port 11, the rear side of the pump body 01 is provided with a hollow cavity 13, the pump body 01 is communicated with the hollow cavity 13 through a hollow cavity connecting port 12, the rear side of the hollow cavity 13 is provided with a pump body water inlet 14, and the rear side of the pump body water inlet 14 is connected with a subsea valve 15.
The method comprises the steps of opening a subsea valve 15, enabling water to enter a pump body from a water inlet 14 of the pump body under the action of centrifugal force, enabling the water to upwards enter a reservoir 05, enabling the water to overflow a piston slide way 06, enabling a piston 10 to be upwards supported by the piston slide way 06 along with buoyancy of the water until a ventilation port 11 is sealed, continuing to flow out along a reservoir water outlet 08, closing the subsea valve 15, closing a centrifugal pump, enabling the reservoir water outlet 08 to form negative pressure due to the one-way conduction effect of a one-way valve 09, enabling the piston 10 and the ventilation port 11 to form negative pressure in the reservoir 05 under the effects of liquid seal and friction force, enabling the liquid to be incapable of flowing back, closing the subsea valve, enabling the water to be always stored in the pump, and avoiding the trouble of manually adding water only by opening the subsea valve and pressing the piston 10 when the pump is used again.
