[0002] Petroleum, a primary target of geological exploration, is a viscous, dark brown liquid often referred to as "the blood of industry." Petroleum reserves exist in certain areas of the Earth's upper crust. Its main components are a mixture of various alkanes, cycloalkanes, and aromatic hydrocarbons, and filtration is required during the processing of crude oil.

[0003] Chinese Patent No. CN201621260649.8 discloses an oil filter, including a filter box. An oil inlet column is provided on one side of the upper surface of the filter box, and a residue outlet pipe is provided at one end of the filter box. A first valve is provided on the residue outlet pipe, and five oil outlets are provided at the lower end of the filter box. The ends of the five oil outlets are all connected to the inlet of a second valve, and a connecting column is connected to the outlet of the second valve. A filter pipe is provided at the lower end of the connecting column, and an oil collection tank is provided at the lower end of the filter pipe. The oil can be initially filtered through the second filter plate and the first filter plate in the filter box.

[0004] In view of this, this utility model is proposed.

[0005] During use, this utility model is very inconvenient because the oil is highly viscous and its filtration by gravity is very slow. Furthermore, the filter element needs to be replaced frequently during the filtration process. Utility Model Content

[0015] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0016] 1. The filtration device, with its dual-barrel setup of a conveying cylinder and a filter cylinder, increases the filtration area for crude oil, thereby improving filtration efficiency.

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] Please see Figure 1-4As shown, this embodiment provides a filtration device for petroleum processing, including a filtration device 1. The filtration device 1 consists of a support 22, a feeding cylinder 2, and a filter cylinder 4. The feeding cylinder 2 is installed at the upper end of the support 22, and the filter cylinder 4 is installed inside the feeding cylinder 2. A pressing mechanism 16 is installed inside the filter cylinder 4. An inlet pipe 20 is installed at the upper end of the feeding cylinder 2, and the bottom end of the inlet pipe 20 extends into the filter cylinder 4. A discharge cylinder 10 is installed at one end of the feeding cylinder 2, and a clamping mechanism 7 is installed inside the discharge cylinder 10, with one end of the clamping mechanism 7 extending into the filter cylinder 4. A collection trough 14 is installed at the bottom end of the feeding cylinder 2, and an outlet pipe 15 is installed at one end of the collection trough 14. A cooling mechanism 21 is installed at one end of the feeding cylinder 2.

[0031] One application of this embodiment is as follows: When the filter device 1 is in use, crude oil is introduced into the filter cylinder 4 inside the filter device 1 through the inlet pipe 20. When the extrusion mechanism 16 is turned on by the switch, it will push forward and extrude the crude oil. When the crude oil is extruded, the liquid will be discharged through the mesh on the upper side of the filter cylinder 4, and the solid waste will continue to be pushed forward. When the solid waste accumulates to a certain amount, it will drive the tightening mechanism 7 to contract, thereby discharging the waste generated by filtration through the discharge cylinder 10. The filtered crude oil will be introduced into the collection tank 14 and then discharged through the outlet pipe 15. During the filtration process, the cooling mechanism 21 can cool down the end of the filter cylinder 4 to avoid high temperature and excessive wear. The filter device 1, with its double-barrel arrangement of the conveying cylinder 2 and the filter cylinder 4, can increase the filtration area of ​​the crude oil and improve the filtration efficiency. Furthermore, the extrusion mechanism 16 extrudes the crude oil, increasing the pressure on the crude oil and improving the separation efficiency between the crude oil and the solid waste.

[0032] In this embodiment, the extrusion mechanism 16 consists of an extrusion screw 3 and a power mechanism 19. The extrusion screw 3 is rotatably installed inside the feed cylinder 2. One end of the extrusion screw 3 passes through the feed cylinder 2 and is installed at the front end of the power mechanism 19. The power mechanism 19 is installed on one side of the feed cylinder 2. When the extrusion mechanism 16 is in use, the power mechanism 19 drives the extrusion screw 3 to rotate. During the rotation, the extrusion screw 3 will push the crude oil forward. During the pushing process, as the blade spacing and the diameter of the central shaft of the extrusion screw 3 increase, the pressure on the crude oil increases, which can extrude and separate the solid and liquid.

[0033] In this embodiment, the power mechanism 19 consists of an electric motor 18 and a transmission 17. The transmission 17 is installed on one side of the conveying cylinder 2, and the electric motor 18 is installed on one side of the transmission 17. When the power mechanism 19 is in use, the electric motor 18 is turned on by a switch, and the electric motor 18 will generate rotational power. The transmission 17 will integrate and output the rotational speed of the electric motor 18.

[0034] In this embodiment, the clamping mechanism 7 consists of a stopper plate 11, a push rod 9, a mounting cylinder 8, and a spring 24.

One end of the push rod 9 is installed on the outside of the stopper plate 11, and the other end of the push rod 9 is slidably installed inside the discharge cylinder 10. The spring 24 is installed inside the discharge cylinder 10 on one side of the push rod 9. When in use, the clamping mechanism 7 seals one end of the filter cylinder 4 through the stopper plate 11 to prevent oil from flowing out during the pushing process. When a large amount of solid waste accumulates, the stopper plate 11 is subjected to greater force, the spring 24 will contract, and one end of the filter cylinder 4 will open to discharge the solid waste.

[0035] In this embodiment, the cooling mechanism 21 consists of a housing 13, a circulation pipe 5, and a connecting pipe 6. The circulation pipe 5 is installed on the outer side of one end of the conveying cylinder 2, the housing 13 is installed on the outer side of the circulation pipe 5, and the connecting pipe 6 is installed at both ends of the circulation pipe 5. When the cooling mechanism 21 is in use, cooling water is introduced into the circulation pipe 5 through the connecting pipe 6. The coolant entering the circulation pipe 5 will cool the inside of the conveying cylinder 2. After absorbing heat, the cooling water is discharged through the connecting pipe 6 to cool down.

[0036] In this embodiment, a heat insulation plate 12 is provided inside the outer casing 13. The heat insulation plate 12 is fixedly installed inside the outer casing 13 by bolts. The heat insulation plate 12 can increase the heat insulation effect of the outer casing 13 and prevent the external temperature from affecting the inside of the cooling mechanism 21 during use.

[0037] In this embodiment, a guide plate 23 is provided on one side of the support 22 at the bottom of the discharge cylinder 10. The guide plate 23 is fixedly installed on one side of the support 22 by bolts.
