Abstract
An improved circulating pump comprises a pump core, a pump valve and a pump shell. The pump core is arranged in the pump shell. The pump valve is placed at the top end of the pump shell, penetrates through the pump shell and is connected with the pump core. A gas valve used for releasing air in the circulating pump is arranged at the top end of the pump shell. The circulating pump further comprises a controller and a sensor. According to the improved circulating pump, air in a circulating pump body and a pipeline can be effectively exhausted, loss caused by production accidents such as air binding and oxygen inflation is lowered, and the improved circulating pump has the advantages of being high in production efficiency, high in production safety and ingenious in design.
Description
Technical field
The utility model relates to the recycle pump using in waste water treatment jet Aeration Technology and Its, particularly a kind of improved recycle pump.
Background technique
Recycle pump is a kind of waste water circulation equipment using in waste water treatment jet Aeration Technology and Its, utilize the vane rotary in recycle pump, make the waste water in recycle pump produce centrifugal force, outwards flow out, thereby realize the circulation of waste water, generally recycle pump and blower support the use.Waste water in aeration tank, in the situation that hydraulic pressure is relatively low, is sent in the inner nozzle of jet aerator by circulating water main by recycle pump, forms one liquid stream at a high speed, and air is also admitted to outer nozzle mouth simultaneously.There is following problem in existing recycle pump: when recycle pump quits work, blower can't stop moment, and can continue to blast air in the recycle pump pump housing and pipeline when work; When recycle pump is started working again, the air that has blasted the recycle pump pump housing and pipeline is difficult to emptying.The problems referred to above often cause the production problems such as air sinuses, oxygen-transfer efficiency be low, thereby affect economic benefit and safety in production.At present, mostly the recycle pump of using in jet Aeration Technology and Its, be not have outlet valve or outlet valve to adopt screw form, easily causes staff's security incident.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of improved recycle pump, can effectively discharge the recycle pump pump housing and ducted air, minimizing is because of the loss causing of the production accidents such as air sinuses, oxygenation, has that manufacturing efficiency is high, production security is high, design feature cleverly.
In order to achieve the above object, the technological scheme that the utility model is taked is:
An improved recycle pump, comprises pump core 1, pump valve 2 and pump case 3, and described pump core 1 is positioned at pump case 3, and described pump valve 2 is positioned at pump case 3 tops, through pump case 3, is connected with pump core 1, and described pump case 3 tops are provided with the air valve 4 for air in release cycle pump.
Described recycle pump also comprises controller and sensor, and described sensor is positioned at recycle pump, is electrically connected to controller; Described air valve 4 is electrically connected to controller, and described controller can be controlled air valve 4 folding venting.
Described air valve 4 is circumscribed with rubber tube, can realize manual folding, exits.
Working principle of the present utility model is:
During work, open pump valve 2, useless water and air drives by vane rotary, inflow pump core 1.When closing, the impeller waste water that stops the rotation stops inflow pump core 1, but blower can't stop moment, so air can inflow pump core 1.Recycle pump generally will be lower than the horizontal plane of liquid in aeration tank, then task is while opening pump valve 2, first opens the air valve 4 that is opened in recycle pump top, and the waste water in aeration tank flows into the recycle pump pump housing, by the air emptying in the pump housing.After air emptying in the pump housing, close gas check valve 4, proceed work.
The beneficial effects of the utility model are:
The utility model is offered air valve 4 on the pump case 3 of recycle pump, realized in the recycle pump pump housing and pipeline in the safety dumping of air pocket, solved the safety problem that recycle pump exists in the course of the work, avoided failing the production problems such as air sinuses that emptying causes, oxygenation because of air in recycle pump, improved manufacturing efficiency.The utlity model has that manufacturing efficiency is high, production security is high, design feature cleverly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Referring to accompanying drawing, the utility model is a kind of improved recycle pump, comprises pump core 1, pump valve 2 and pump case 3, described pump core 1 is positioned at pump case 3, described pump valve 2 is positioned at pump case 3 tops, through pump case 3, is connected with pump core 1, and described pump case 3 tops are provided with the air valve 4 for air in release cycle pump.
Described recycle pump also comprises controller and sensor, and described sensor is positioned at recycle pump, is electrically connected to controller; Described air valve 4 is electrically connected to controller, and described controller can be controlled air valve 4 folding venting.
Described air valve 4 is circumscribed with rubber tube, can realize manual folding, exits.In waste water treatment jet Aeration Technology and Its, the waste water in aeration tank, in the situation that hydraulic pressure is relatively low, is sent in the inner nozzle of jet aerator by circulating water main by recycle pump, forms one liquid stream at a high speed, and air is also admitted to outer nozzle mouth simultaneously.Existing recycle pump is existing problems when work, and when recycle pump quits work, blower can't stop moment, and can continue to blast air in the recycle pump pump housing and pipeline.When recycle pump is started working again, first open the air valve 4 that is opened in recycle pump top, the waste water in aeration tank flows into the recycle pump pump housing, by the air emptying in the pump housing.
During work, open pump valve 2, useless water and air drives by vane rotary, inflow pump core 1.When closing, the impeller waste water that stops the rotation stops inflow pump core 1, but blower can't stop moment, so air can inflow pump core 1.Recycle pump generally will be lower than the horizontal plane of liquid in aeration tank, then task is while opening pump valve 2, first opens the air valve 4 that is opened in recycle pump top, and the waste water in aeration tank flows into the recycle pump pump housing, by the air emptying in the pump housing.After air emptying in the pump housing, close gas check valve 4, proceed work.
