[0002] Petroleum, one of the main objects of geological exploration, is a dark brown liquid, known as the blood of industry. Petroleum is stored in some areas of the upper crust. The main components are a mixture of various alkanes, cycloalkanes, and aromatic hydrocarbons. Petroleum extraction refers to the act of digging and extracting petroleum in places where petroleum is stored. In the process of extracting petroleum, it is usually collected by drilling oil wells. However, oil fields will inevitably cause pollution to the petroleum during the drilling process. The petroleum contains sand and other fine impurities. When processing the petroleum, it is necessary to use a filter to filter out the impurities. Therefore, when collecting the extracted petroleum, it is necessary to filter and purify it in time.

[0016] The operator moves the equipment to the designated location for use. At the same time, in order to solve the problem that the feed pipe opening is easily blocked when the crude oil is fed, the oil is poured into the feed hopper. The oil will flow along the oil inlet pipe. At this time, the impeller arranged inside the feed cavity will be rotated by the flow of oil. At the same time, the reciprocating screw will drive the rubber knocking plate that is limited and slides inside the limit groove to move. The rubber knocking plate moves up and down along the reciprocating screw, and then the rubber knocking plate knocks the bottom of the oil inlet pipe back and forth, so that the oil inlet pipe vibrates, which is beneficial to prevent sand impurities in the oil from adhering to the inner cavity of the oil inlet pipe.

The design is ingenious and improves the use effect of the equipment;

[0018] The oil will flow into the filter cavity through the oil inlet pipe, and then the oil will pass through the filter screen, which will filter the impurities in the oil. The impurities in the oil will remain on the surface of the filter screen, and the filtered oil will be discharged from the discharge pipe. The transparent viewing window is set to facilitate the operator to observe the impurities on the surface of the filter screen at any time;

[0019] When the filter screen needs to be cleaned and maintained, the first installation component is used, and the hydraulic cylinder is started. The hydraulic cylinder performs a contraction movement to drive the card block to contract, so that it is separated from the card slot block, and the two sets of springs originally compressed by the filter screen will return to their original state, and a thrust will be generated to push the filter screen toward the outside of the filter cavity. At this time, it is convenient for the user to directly extract the filter screen and clean the filter screen;

[0020] After cleaning, the filter screen is slid back into the filter mounting slot of the filter cavity, and the filter screen is completely pushed into the filter cavity until it returns to its original position. The two sets of springs are compressed, and the card slot block set on the rear side of the filter screen corresponds to the card block position, so that the hydraulic cylinder extends, and the hydraulic cylinder pushes the card block until it completely enters the card slot block. The card block and the card slot block are engaged and fixedly connected, that is, the filter screen is re-fixed in the filter cavity. This arrangement can filter sand and other fine impurities in the oil through the filtering assembly, and at the same time it is convenient for users to replace the filter screen, thereby improving the practicality of the device.

[0021] 6. Through three different installation components, the filter screen plate and the filter chamber can be disassembled and installed in different ways, and the applicable situations are different, which can meet the needs of different users and improve the application scope of the device.
