Description

Technical Field

[0001] The utility model relates to the technical field of oily waste treatment, in particular to an oily waste separation device. Background Art

[0002] Oily waste is solid waste generated during the oil field production process. It is a special operating well site oily solid waste formed by the mixture of crude oil, wastewater, surface soil and waste steel slag used to pave the well site ground during underground operations. Oily waste cannot be discarded directly and the crude oil must be separated before the remaining solids can be processed.

[0003] Existing oily waste separation devices usually do not have a squeezing function, and it is difficult to separate the oil from the waste. Therefore, some people usually set a squeezing roller at the feed inlet to squeeze the waste. For example, the Chinese utility model patent with announcement number CN211706144U specifically discloses a separation and filtering device for oily waste treatment.

[0004] However, in actual use of the above-mentioned separation device for oily waste, people will find that the device separates waste and oil by setting an inclined filter screen. However, during the separation process, the waste generally needs to be settled for a period of time to separate the residual oil in the waste. When the above-mentioned device is used for separation, the waste falls on the filter screen and is separated, and it is easy to be directly discharged, which greatly reduces the separation effect.
