Embodiment 1

[0027] A kind of oil filtering device with impurity cleaning function, such as figure 1 and figure 2 As shown, it includes a first filter pipe 1, a filter plate 2, a communication pipe 3, an impurity circulation pipe 301, a second filter pipe 4, a filter element 5, a rotor pump 6, a solenoid valve 7, a second solenoid valve 701 and a third solenoid valve. Valve 702, the first filter pipe 1 is fixedly installed on the oil pipeline through bolts, the first filter pipe 1 is slidingly connected with the filter plate 2, there are at least two filter plates 2, two communication pipes 3 are provided, and the two communication pipes 3 are respectively installed on the lower part of the first filter pipe 1 through bolts, the second filter pipe 4 is fixedly connected to the communication pipe 3, and two impurity circulation pipes 301 are provided, and the impurity circulation pipe 301 communicates with the first filter pipe 1 and the second filter pipe 4. A filter element 5 is detacha...

Embodiment 2

[0039] On the basis of Example 1, such as figure 2 , Figure 4 and Figure 5 As shown, in addition to removing the impurities in the first filter tube 1 in the state of petroleum transportation, the filter device needs to clean the filter plate 2 and filter element 5 regularly during the long-term use of the device. The pump 6 provides power, the crude oil circulates counterclockwise to make the filter plate 2 realize regular self-cleaning, prolongs the service time of the filter plate 2, reduces the replacement frequency of the filter plate 2, and the crude oil circulates clockwise to make the filter element 5 realize regular self-cleaning, When the filter plate 2 needs to be cleaned, the staff will open the first solenoid valve 7 and the second solenoid valve 701 on the connecting pipe 3 to fill the first filter pipe 1 and the second filter pipe 4 with crude oil, and then filter the first The valves at both ends of the pipe 1 are all closed to cut off the flow of the oil ...

Embodiment 3

[0041] On the basis of Example 2, such as figure 2 and Figure 5 As shown, after a long period of use of the device, the filter plate 2 and the filter element 5 need to be deeply cleaned and maintained or replaced. After the impurities are removed, and the oil pipeline is cut off, the oil in the device is released through the sewage outlet pipe 401, and the staff removes the bolts connecting the first filter pipe 1 and the filter plate 2, and then directly pulls the filter plate 2 outward. Pull out obliquely, and then replace the maintained or new filter plate 2 into the first filter tube 1, then fix the filter plate 2 on the first filter tube 1 by bolts, and remove the second filter plate 2 when replacing the filter element 5 Bolts on both sides of the second filter tube 4, remove the second filter tube 4 in the lower half, directly disassemble the filter element 5, then remove the impurities attached to the second filter tube 4 and maintain and replace the filter element 5...

Abstract

The invention relates to the field of oil field petroleum filtering, in particular to a petroleum filtering device with an impurity cleaning function and for an oil field. The petroleum filtering device comprises a first filter pipe, a filter plate, a second filter pipe, a filter element and the like, wherein the first filter pipe is mounted on an oil pipeline, the filter plate is arranged in the first filter pipe, the second filter pipe communicates with the first filter pipe through a communicating pipe, and the filter element is arranged in the second filter pipe. According to the invention, solid impurities of petroleum are filtered through cooperation of the first filter pipe and the filter plate; the solid impurities in the first filter pipe are collected to the second filter pipe through cooperation of a rotor pump and an electromagnetic valve, the filtered impurities are stored in the second filter pipe through the filter element, and the solid impurities are filtered through cooperation of the rotor pump and the first filter pipe and the second filter pipe, so the filter plate and the filter element in the device are self-cleaned; and the first filter pipe and the filter plate are detachable, and the second filter pipe and the filter element are detachable, so the operation of replacing the filter plate and the filter element by a worker becomes simple.

Description

technical field [0001] The invention relates to the field of supporting devices for oil production in oil fields, in particular to a petroleum filtering device for oil fields with the function of cleaning impurities. Background technique [0002] Petroleum is a viscous, dark brown liquid known as "industrial blood". Since the early 1950s, my country has carried out oil and gas exploration in 82 major large and medium-sized sedimentary basins, and discovered more than 500 oil fields As a raw material for many chemical industrial products such as solvents, fertilizers, pesticides and plastics, petroleum has a wide range of applications and great use value. [0003] After extracting oil from existing oilfields, before subsequent dehydration, refining, and purification, in order to avoid affecting the equipment for subsequent operations, oil filtration devices are used to filter the solid impurities in the oil; existing oil filters generally pass The Y-type filter is realized. W...
