In case 2, as shown in fig. 5 (B), at this time, the liquid level inside the oil-water separation chamber 14 does not reach the height of the oil discharge port 141, but a thick oil layer is accumulated on the liquid level and cannot be discharged through the oil discharge port 141 in time, at this time, the first resistance sensing controller 3111 and the second resistance sensing controller 3112 sense the oil layer and trigger the oil layer, and send a control signal to the centralized control module 4, the centralized control module 4 controls the oil pump 312 to operate, so as to pump the upper oil layer away until the second resistance sensing controller 3112 does not sense the oil layer, and at this time, the oil pump 312 stops operating.
In case 3, as shown in fig. 5 (C), at this time, there is almost no oil layer on the liquid level in the oil-water separation chamber 14, at this time, the first resistance sensing controller 3111 does not sense an oil layer, but the kitchen waste liquid further flows in, so that the water level rises, that is, the oil drain port 141 is overflown, at this time, the first water level sensor 3211 located in the water drain chamber 15 and lower than the oil drain port 411 senses that the water level in the water drain chamber 15 is about to overflow the oil drain port 141, the first water level sensor 3211 sends a control signal to the centralized control module 4, the centralized control module 4 controls the water pump 322 to start, and the water is pumped back into the filtration chamber 13 through the water input pipe 323 and the water output pipe 324 until the liquid level in the water drain chamber 15 is pumped to be lower than the height of the second water level sensor 3212, and at this time, the water pump 322 stops operating.
It should be noted that, in the solution of patent CN114516695A, due to the lack of the liquid level control system 3, if the oil content of the kitchen residual liquid is too high, and meanwhile, under the condition of low kitchen residual liquid flow, the liquid level in the box 11 does not reach the height of the oil discharge port, at this time, the oil layer of the box is easy to accumulate, and after a long time, the oil layer is easy to condense and even easily emit odor in high temperature weather, and under the condition of low oil content of the kitchen residual liquid and too high kitchen residual liquid flow, the oil is discharged only through the oil discharge port 141, and the situation that the kitchen residual liquid is discharged into the oil collection barrel through the oil discharge port 141 is easy to occur, so as to pollute the oil collected in the oil collection barrel.
This scheme has set up liquid level control mechanism to this problem, extracts the oil reservoir through oily extraction mechanism by force, has avoided above-mentioned condition.
Through liquid level control mechanism 3 makes the liquid level in the box 11 maintains in certain altitude range always, simultaneously according to the different situation of oil level and water level, in time handles through oil extraction mechanism 31, hydrologic cycle mechanism 32, and the oil reservoir in the box 11 is discharged after extracting to the oil drain port through oil extraction mechanism 31, has further avoided behind the surplus liquid in kitchen to spill over the oil drain port, and the surplus liquid in kitchen pollutes the oil water quality after the separation through oil drain port 141.
