Embodiment
It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer
Accompanying drawing in type embodiment, the technical scheme in the embodiment of the utility model is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model part of the embodiment, rather than whole embodiments.Based on the implementation in the utility model
Example, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, is belonged to
The scope of the utility model protection.
Fig. 1 is refer to, Fig. 1 is the structural representation for the water fetching device that the utility model embodiment provides.
The water fetching device that the utility model embodiment provides, including the pump housing 5 being fixed on the cell wall of waste water storage tank, the pump housing
5 entrance is provided with turbidity detection device, in addition to the body 1 that stretches into and can be floated in waste water storage tank, one end of body 1 with
The pump housing 5 connects, and its other end is provided with filter screen 2 and is fixed with floating drum 3.The entrance of body 1 floats all the time in the presence of floating drum 3
In waste water storage tank in the clear liquid on the upper strata of waste water, and water level can be followed to move up and down, be taken out by turbidity detection device detection
The clear liquid gone out ensures water quality, it is not necessary to waits draining again after precipitation completely, improves efficiency of producing drinking water, and ensures that symbol can be got at any time
The supernatant liquor of turbidity is closed, ensures only to take turbidity qualified waste water in upper strata during water intaking, the underproof continuation of turbidity is sunk in storage tank
Form sediment and clarify.
Wherein, turbidity detection device is transmissometer 4, increases transmissometer 4, transmissometer 4 and storage tank by the entrance in the pump housing 5
Connection can be connected by pipe flange, also centralized control room can be sent to by pipe clamp etc., the turbidity data of transmissometer 4, with the pump housing 5
Start and stop do interlocked control, once turbidity is unqualified, the pump housing 5 is stopped.Generally, control requirement can be according to actual feelings
The automatic start pump housing 5, the pump housing 5 is automatically stopped when turbidity reaches 500NTU, i.e., according to turbid when condition setting turbidity reaches 300NTU
Spend 500NTU and require design, pump housing technical parameter can be combined and require to add the entry condition of the pump housing 5.
Certainly, turbidity detection device can also be the observation window being opened on waste water storage tank outer wall pipeline, in turbidity requirement
Be not it is so strict in the case of realized semi-automation mobile fetch water by personal observations.Turbidity detection device can also be density
Instrument, or be solid content detector.
Wherein, body 1 is flexible pipe, can install floating drum 3, specially cladded type floating drum close to the side of filter screen 2 in flexible pipe,
Floating drum 3 selection only need to consider buoyancy can carry completely the utility model embodiment offer water fetching device in storage tank group
The weight of part, i.e. floating drum 3 will ensure that hose free end can lift with height of liquid level, and the installation of floating drum 3 will consider flexible pipe certainly
There is certain flexibility by end, the gravity of filter screen 2 can be relied on filter screen 2 is voluntarily hung down in medium, ensure that filter screen 2 below liquid level, is prevented
Only the pump housing 5 sucks air.Wherein, body 1 is connected with the pump housing 5 by flange.
It is of course also possible to it is body 1 for hard tube and is flexible coupling with the pump housing 5.Flexible pipe can be changed into rigid tubing and add be flexible coupling
