Specific embodiment
The technical issues of to solve the utility model, the technical solution of use and the technical effect that reaches are clearer,
The utility model is described in further detail with reference to the accompanying drawings and examples.It is understood that described herein
Specific embodiment is used only for explaining the utility model, rather than the restriction to the utility model.It also should be noted that being
Convenient for description, part relevant to the utility model is illustrated only rather than full content in attached drawing.
Fig. 1 is the structural schematic diagram of grease decker provided by the utility model.As shown in Figure 1, the utility model is real
Apply the grease decker of example offer, comprising: grease inlet tube 1, communicating pipe 2, oil water mixture storage tank 4 and П shape pipe unit.
The setting of grease inlet tube 1 is opened up in 4 top of oil water mixture storage tank, 4 side wall of oil water mixture storage tank
Multiple oil discharge outlets 9 of different height；The discharge outlet of 4 bottom of oil water mixture storage tank is connect with П shape pipe unit；The П
The drainpipe of shape pipe unit is connect with external sewage draining exit or water collecting device, and the drainpipe of the П shape pipe unit and external row
Third valve 8 is set between dirty mouth or water collecting device.
The П shape pipe unit includes main П shape pipe 3 and multiple П shape pipes 5 in parallel in the vertical direction, the main П
For shape pipe 3 above branch П shape pipe 5, multiple 5 height of П shape pipe are different；The main П shape pipe 3 passes through communicating pipe 2 and oil mixing with water
It is connected at the top of object storage tank 4, the first valve 6 is set on the communicating pipe 2；It is arranged second in the horizontal pipeline of the branch П shape pipe 5
Valve 7.
In addition, liquid level meter is also set up in the oil water mixture storage tank 4, for measuring grease in oil water mixture storage tank 4
The liquid level of mixture.
Under conditions of oil water mixture processing flow is certain, the utility model is opened up in 4 side wall of oil water mixture storage tank
Multiple oil discharge outlets 9 of different height can select oil discharge outlet 9 according to the height of determining grease layering interfaces.
The working principle of the utility model grease decker: oil water mixture enters oil mixing with water by grease inlet tube 1
Object storage tank 4, due to steady-flow, liquid level remains unchanged in oil water mixture storage tank 4 in flow process, flowing law
Obey fluid dynamics fundamental equation.Additionally, due to technique requirement, oil water mixture flow and flow rate is smaller, and (ordinary circumstance flows down
Fast u < 0.5m/s), water fluid resistance loss in pipeline can be ignored.П shape pipe is set by oil water mixture storage tank 4
Unit, the present embodiment are illustrated by taking a main П shape pipe 3 and a branch П shape pipe 5 as an example.The height of main П shape pipe 3 is h2,
The height of branch П shape pipe 5 isWhen closing the second valve 7, the first valve 6 is opened and when third valve 8, water is from main П shape pipe 3
It flows through, at this time using grease layering interfaces in oil water mixture storage tank 4 as section one, communicating pipe 2 and main 3 intersection of П shape pipe are to cut
Face two arranges Bernoulli equation:
Wherein, u1≈ 0, u2=u, p1=pa+ρOilg(H-h1), p2=pa
Due to u very little, thereforeIt is negligible；The ratio between the density of oil and water is approximately 0.75 under normal circumstances, in arrangement
Formula obtains h1=4h2- 3H, wherein H indicates the height of oil interface in oil water mixture storage tank 4, can be measured by liquid level meter, steady-state flow
It is dynamic lower for definite value；H1 indicates the height of grease layering interfaces in oil water mixture storage tank 4, and h2 indicates the height of main П shape pipe 3.It can
See, the height of oil interface can be obtained by measurement in H oil water mixture storage tank 4, if main 3 height h of П shape pipe2It determines, grease is mixed
Close the height h of water termination (grease layering interfaces) in object storage tank 41It just can determine that, that is, can determine oily in oil water mixture storage tank 4
Height is distributed, and then the position of oil extraction pipe nozzle also can determine that vice versa.
Similarly, when the first valve 6, the second valve 7 and third valve 8 are opened, water from be in low level branch П shape pipe 5
It flows through, at this time also using grease layering interfaces in oil water mixture storage tank 4 as section one, communicating pipe 2 is with 7 intersection of the second valve
Section two, column Bernoulli equation can obtain:
Wherein,Indicate the height of grease layering interfaces in oil water mixture storage tank 4 at this time,Indicate branch П shape pipe 5
Highly.Due toThereforeCan so it be drawn a conclusion: if П shape pipe setting height value is larger, oil water mixture
The position of grease layering interfaces is just higher in storage tank 4, otherwise just low.
In the present embodiment, two oil discharge outlets can be respectively set in 4 upper and lower part appropriate location of oil water mixture storage tank
9, i.e. high position oil discharge outlet and low level oil discharge outlet.High-order oil discharge outlet corresponds to main П shape pipe 3, and low level oil discharge outlet corresponds to branch П shape pipe 5.One
As in the case of, 9 center of oil discharge outlet is at the position of 4 short transverse of oil water mixture storage tank is away from 50mm on grease layering interfaces.This
Sample, can be by the height of pipeline in the switch-mode regulation П shape pipe unit of valve, to control the position of oil discharge outlet 9.
The use process of the utility model:
1, according to the short transverse position of storage tank high position oil discharge outlet, the height of main П shape pipe 3 is determined.When work, the is closed
Two valves 7, when opening the first valve 6 and the second valve 8, water is flowed through from main П shape pipe 3, and grease is discharged from high-order oil discharge outlet.
2, according to the short transverse position of storage tank low level oil discharge outlet, the height of branch П shape pipe 5 is determined.When work, the is opened
When one valve 6, the second valve 7 and the second 8 valve of valve, water is flowed through from branch П shape pipe 5, and grease is discharged from low level oil discharge outlet.
To sum up, position (the i.e. oil extraction of grease layering interfaces can be arranged according to oil water mixture tank structure in the utility model
The position of mouth), П shape pipeline height is determined again by calculating；It in turn, can also be according to fixed П shape pipeline height, to set
Set the position (i.e. the position of oil extraction outlet) of grease layering interfaces.In practice, multiple height can be set according to the actual situation
Branch П shape pipe 5, to obtain the position (i.e. grease layering interfaces) of multiple oil discharge outlets 9, for operation convenience is provided.
Finally, it should be noted that the above various embodiments is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should
Understand: it is modified the technical solutions described in the foregoing embodiments, or to some or all of the technical features
It is equivalently replaced, the scope of the technical solutions of the embodiments of the utility model that it does not separate the essence of the corresponding technical solution.
