Problems solved by technology

[0002] As we all know, the oil extraction device for petroleum residue is an auxiliary device for petroleum processing, which has been widely used in the field of petroleum refining; an existing oil extraction device for petroleum residue includes a filter box, and the inside of the filter box is set There is a working chamber, the top of the filter box is provided with an operation port, and the operation port is connected with the working chamber. There are multiple sets of legs at the bottom of the filter box, and a cover plate is detachable at the operation port. There is a valve on it; when an existing oil extraction device for petroleum residue is used, firstly, the petroleum residue is introduced into the working chamber through the operating port, then the cover is closed, and then the petroleum residue is precipitated, and finally the precipitated petroleum residue is It can be sucked away by the oil pump, and the remaining residue can be discharged through the sewage pipe; in the use of an existing petroleum residue oil extraction device, it is found that during the oil extraction process, the oil residue is a mixture of oil and crushed stone residue during the extraction process. Extraction is generally carried out by precipitation, but the precipitation process takes a long time, resulting in low extraction efficiency and poor practicability of the device
