In actual use, as shown in fig. 1-8, firstly, intermittently injecting an oil-water mixture into the oil-water storage tank 1 through the oil-water injection nozzle 11 of the oil separator, when the liquid level of the oil-water mixture reaches the first liquid level meter 5, the first liquid level meter 5 sends a liquid level signal to the control module 4, the control module 4 receives the liquid level signal and then sends a control signal to an external feeding mechanism electrically connected with the control module 4, so that the external feeding mechanism stops feeding the oil-water mixture, and the oil separator enters a standing separation state. After standing for a preset time, the oil-water mixture realizes oil-water separation, and the grease density is higher than the water density and floats on the upper layer. Then, the control module 4 sends a control signal to the fast water adding switch 321, the fast water adding switch 321 is turned on to inject water to the bottom of the oil separator, the volume of the lower water is increased, the upper oil layer is pushed to move upwards until the upper oil layer reaches the second liquid level meter 6, the second liquid level meter 6 sends a liquid level signal to the control module 4, and the control module controls the control module to control the upper oil layer to move upwards and downwardsAfter receiving the liquid level signal, the block 4 sends a control signal to the fast water adding switch 321, the fast water adding switch 321 is turned off, and meanwhile, the control module 4 sends a control signal to the slow water adding switch 331 and turns on the slow water adding switch 331. The slow water adding switch 331 controls the water adding speed to be slow, so that the fluctuation of the water level in the oil separator when water flows into the oil separator can be reduced, and the fluctuation of the water level in the water inlet buffer tube 31 can be reduced, so that the detection of the third liquid level meter 7 is more accurate. When the liquid level reaches the third liquid level meter 7, the third liquid level meter 7 sends the liquid level signal to the control module 4, after the control module 4 receives the liquid level signal, the control module delays to send the control signal to the slow water adding switch 331, the slow water adding switch 331 is turned off, and the delay time is set according to the actual situation. When the liquid level reaches the third level gauge 7, it is described that only a small amount of grease is stored in the grease trap in the oil/water injection nozzle 11, and the remaining height (h) of the grease is Oil ) And the height difference between the water level measured by the third liquid level meter 7 and the oil-water mixture inlet (Δ h = h) 4 oil －h 4 water ) And density of water and oil (p) Water (W) 、ρ Oil ) The specific relationship is as follows: h is Oil =△h×ρ Water (W) /（ρ Water (W) －ρ Oil ) From this equation, the third level gauge 7 can indirectly indicate the height of the oil-water interface in the grease trap, and the remaining grease height is proportional to Δ h, where: the area of the water inlet buffer pipe 31 is S1, the area of the oil-water injection nozzle 11 is S2, and the water inlet pipe 3 only needs to be added with water again with the volume of V Adding =h Oil And (S1 + S2), and the grease in the grease trap can be completely discharged by adding water in a delayed manner.
After the water is added in a delayed manner, the control module 4 sends a control signal to the drain switch 81 to open the drain switch 81 in a delayed manner, after a preset discharge time, all water in the oil separator is discharged, and at the moment, the control module 4 controls the drain switch 81 to be closed, so that the processes of oil-water separation and grease collection are completed.
In the utility model, the first liquid level meter 5 and the second liquid level meter 6 can adopt liquid level meter models with lower precision and stronger adaptability; the third liquid level meter 7 needs to adopt a specification model with higher precision so as to improve the accurate value read by an oil-water interface, and because the third liquid level meter 7 detects the clean water surface position and cannot be influenced by grease in an oil-water mixture, the selectable liquid level meters have more models and lower cost. Compared with the conventional method for detecting the oil-water interface, the detection method can avoid direct contact with the oil-water mixture, is not influenced by grease, and has high measurement precision and stable working state.
The above-mentioned techniques not specifically mentioned refer to the prior art.
As noted above, while the invention has been shown and described with reference to certain preferred embodiments, it is not to be construed as limited to the invention itself. Various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
