Description

Technical Field

[0001] The present invention relates to the technical field of mineral oil equipment, and specifically relates to a mineral oil refining equipment. Background Art

[0002] Mineral oil generally refers to crude oil (or petroleum) after mining and primary processing. Petroleum is a natural mineral buried underground. The unrefined petroleum extracted through exploration and mining is also called crude oil. At normal temperature, the finished product after refining crude oil is called petroleum product. According to custom, the base oil obtained by physically distilling petroleum is called mineral oil base oil. The refining process mainly involves separating crude oil into different parts to obtain the required products. The main separation processes include the distillation separation of crude oil into straight-run gasoline, straight-run kerosene, straight-run diesel, heavy diesel, various lubricating oil fractions, cracking stock, and residue (also called residual oil), and the solvent separation used for purifying various lubricating oils.

[0003] Before refining treatment, mineral oil generally needs to filter the crude oil to filter out the impurities contained in the crude oil. However, when the existing mineral oil refining equipment filters the impurities in the crude oil through a filter plate, the impurities are easily accumulated on the upper surface of the filter plate, causing blockage of the filter plate, and it is necessary to frequently clean the impurities on the filter plate, increasing the working intensity of the staff. At the same time, during the refining process of the crude oil, the impurities are easily attached to the inner side wall of the treatment tank due to the coking effect of high temperature, which is inconvenient for cleaning the impurities and brings inconvenience to the staff. Summary of the Invention

[0004] Aiming at the problems in the prior art, the present invention provides a mineral oil refining equipment.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a mineral oil refining equipment, including a bottom plate and a treatment tank fixedly connected above the bottom plate;

[0006] The top of the treatment tank is movably connected with a moving frame, a filter plate is fixedly connected to the moving frame, filter holes are opened on the filter plate, a first rotating cylinder and a second rotating cylinder are respectively rotatably connected above and below the moving frame, a cleaning block is fixedly connected to the circumferential outer wall of the first rotating cylinder, the cleaning block corresponds to the top end of the filter hole, and a scraping block is fixedly connected to the circumferential outer wall of the second rotating cylinder, and the scraping block corresponds to the bottom end of the filter hole and the inner side wall of the treatment tank respectively;

[0007] The bottom of the treatment tank is movably connected with a loading tank.

[0008] Specifically, a hydraulic rod is fixedly connected to the outer side wall of the processing box. The movable end of the hydraulic rod is fixedly connected to a connecting rod, the bottom end of the connecting rod is fixedly connected to a first driving motor, and the driving shaft of the first driving motor is fixedly connected to a connecting rod, which is fixedly connected to the moving frame.

[0009] Specifically, a fixing rod is fixedly connected to the connecting rod, and the fixing rod is fixedly connected to the loading box.

[0010] Specifically, a first rotating shaft and a second rotating shaft are respectively fixedly connected to the first rotating cylinder and the second rotating cylinder, and both the first rotating shaft and the second rotating shaft are rotatably connected to the side wall of the moving frame.

[0011] Specifically, a second driving motor is fixedly connected to the moving frame. The driving shaft of the second driving motor is fixedly connected to the first rotating shaft. Pulley wheels are fixedly connected to both the first rotating shaft and the second rotating shaft, and a belt is connected between the two pulley wheels.

[0012] Specifically, a storage cavity is formed inside the side wall of the moving frame. A plug is threadedly connected to the top end of the storage cavity. A discharge hole is formed in the side wall of the storage cavity, and a blocking block is movably connected to the discharge hole.

[0013] Specifically, a first spring is fixedly connected to the outer side wall of the moving frame, and one end of the first spring is fixedly connected to the blocking block.

[0014] Specifically, a pushing block is fixedly connected to the inner side wall of the processing box, and the pushing block corresponds to the blocking block.

[0015] Specifically, an airbag is fixedly connected to the upper surface of the bottom plate. The airbag is communicated with an air inlet pipe, and a one-way valve is installed on the air inlet pipe. An air outlet pipe is fixedly connected to the moving frame and is arranged towards the inner side wall of the processing box. The air outlet pipe is communicated with the airbag through a connecting pipe.

[0016] Specifically, a connecting block is fixedly connected to the outer side wall of the airbag, and the bottom end surface of the connecting block is fixedly connected to a second spring, which is fixedly connected to the upper surface of the bottom plate.

[0017] Advantages of the present invention:

[0018] 1: A cleaning block is movably connected above the filter plate to prevent impurities in the crude oil from evenly accumulating on the upper surface of the filter plate and blocking the filter holes. When the second drive motor operates, the first rotating shaft rotates. During the rotation of the first rotating shaft, the first rotating cylinder rotates. During the rotation of the first rotating cylinder, the cleaning block rotates. The rotation of the cleaning block sweeps the impurities on the upper surface of the filter plate to the upper left of the filter plate. Since the crude oil is viscous, the first rotating cylinder and the cleaning block act to stir the crude oil above the filter plate, facilitating the flow of the crude oil.

[0019] 2: A scraping block is rotatably connected below the moving frame, and the scraping block acts on the inner wall of the treatment tank. During the refining process of the crude oil in the treatment box, due to high-temperature coking, impurities will adhere to the inner wall of the treatment box. The scraping block is used to clean the impurities on the inner wall of the treatment box. When the second drive motor operates, the first rotating shaft rotates. Since pulley wheels are fixedly connected to both the first rotating shaft and the second rotating shaft, the pulley wheels rotate during the rotation of the first rotating shaft. At the same time, the second rotating shaft rotates through the belt. During the rotation of the second rotating shaft, the second rotating cylinder rotates, that is, the scraping block acts on the inner wall of the treatment tank. The interaction between the scraping block and the inner wall of the treatment tank facilitates scraping off the viscous impurities adhering to the inner wall of the treatment tank and dropping them into the loading box. At the same time, the cleaning liquid is used to clean the inner wall of the treatment tank.

[0020] 3: An airbag is provided below the loading box, facilitating blowing the gas in the airbag through the air outlet pipe onto the inner wall of the treatment box, facilitating blowing the residual liquid on the inner wall of the treatment tank to move downward, and realizing the cleaning of the inner wall of the treatment tank.

[0021] The present invention facilitates the flow of crude oil into the treatment box for refining, and after the refining process, it facilitates the cleaning of the impurities adhering to the inner wall of the treatment box. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0030] As Figures 1-5 shown, a mineral oil refining device of the present invention includes a bottom plate 1 and a processing box 2 fixedly connected above the bottom plate 1;

[0031] The top end of the processing box 2 is movably connected with a moving frame 3, a filter plate 4 is fixedly connected to the moving frame 3, filter holes 9 are formed in the filter plate 4, a first rotating cylinder 5 and a second rotating cylinder 6 are respectively rotatably connected above and below the moving frame 3, a cleaning block 7 is fixedly connected to the circumferential outer wall of the first rotating cylinder 5, the cleaning block 7 corresponds to the top end of the filter hole 9, and a scraping block 8 is fixedly connected to the circumferential outer wall of the second rotating cylinder 6, and the scraping block 8 corresponds to the bottom end of the filter hole 9 and the inner wall of the processing box 2 respectively;

[0032] The bottom of the processing box 2 is movably connected with a loading box 10.

[0033] A hydraulic rod 11 is fixedly connected to the outer side wall of the processing box 2. The movable end of the hydraulic rod 11 is fixedly connected to a connecting rod 12. The bottom end of the connecting rod 12 is fixedly connected to a first driving motor 13. The driving shaft of the first driving motor 13 is fixedly connected to a connecting rod 14. The connecting rod 14 is fixedly connected to the moving frame 3. The hydraulic rod 11 works to move the moving frame 3 downward through the connecting rod 12, so as to realize the movement of the moving frame 3 inside the processing box 2. During the movement of the moving frame 3, the pushing block 26 acts on the blocking block 24, so as to realize the movement of the blocking block 24, that is, to realize that the cleaning liquid in the storage cavity 21 flows to the inner side wall of the processing box 2 through the discharge hole 23. At the same time, the second driving motor 18 works to rotate the first rotating shaft 16. At the same time, since pulley 19 is fixedly connected to both the first rotating shaft 16 and the second rotating shaft 17, during the rotation of the first rotating shaft 16, the pulley 19 rotates. At the same time, the second rotating shaft 17 rotates through the belt 20. During the rotation of the second rotating shaft 17, the second rotating cylinder 6 rotates. Since the scraping block 8 is fixedly connected to the circumferential outer side wall of the second rotating cylinder 6, during the rotation of the second rotating cylinder 6, the scraping block 8 rotates. At the same time, since one end of the scraping block 8 is attached to the inner side wall of the processing box 2, during the rotation of the scraping block 8, the viscous impurities attached to the inner side wall of the processing box 2 are scraped off and fall into the loading box 10. At the same time, the cleaning liquid realizes the cleaning effect on the inner side wall of the processing box 2.

[0034] A fixed rod 15 is fixedly connected to the connecting rod 12. The fixed rod 15 is fixedly connected to the loading box 10.

[0035] A first rotating shaft 16 and a second rotating shaft 17 are respectively fixedly connected to the first rotating cylinder 5 and the second rotating cylinder 6. The first rotating shaft 16 and the second rotating shaft 17 are both rotatably connected to the side wall of the moving frame 3. Through the first rotating shaft 16 and the second rotating shaft 17, it is convenient to realize the rotation of the first rotating cylinder 5 and the second rotating cylinder 6.

[0036] A second driving motor 18 is fixedly connected to the moving frame 3. The driving shaft of the second driving motor 18 is fixedly connected to the first rotating shaft 16. Pulley 19 is fixedly connected to both the first rotating shaft 16 and the second rotating shaft 17. A belt 20 is connected between the two pulleys 19. The second driving motor 18 works to rotate the first rotating shaft 16. At the same time, since pulley 19 is fixedly connected to both the first rotating shaft 16 and the second rotating shaft 17, during the rotation of the first rotating shaft 16, the pulley 19 rotates. At the same time, the second rotating shaft 17 rotates through the belt 20.

[0037] A storage cavity 21 is formed inside the side wall of the movable frame 3. A plug 22 is threadedly connected to the top end of the storage cavity 21. A discharge hole 23 is formed in the side wall of the storage cavity 21. A blocking block 24 is movably connected inside the discharge hole 23. Before adding the cleaning liquid into the storage cavity 21, the staff manually rotates the plug 22 to remove the plug 22 from the storage cavity 21. Then, the cleaning liquid is added into the storage cavity 21. After that, the plug 22 is rotated in the reverse direction to install the plug 22 on the storage cavity 21.

[0038] A first spring 25 is fixedly connected to the outer side wall of the movable frame 3. One end of the first spring 25 is fixedly connected to the blocking block 24. The arrangement of the first spring 25 facilitates the elastic connection of the blocking block 24 to the outer side wall of the movable frame 3.

[0039] A pushing block 26 is fixedly connected to the inner side wall of the processing box 2. The pushing block 26 corresponds to the blocking block 24.

[0040] An airbag 27 is fixedly connected to the upper surface of the bottom plate 1. The airbag 27 is communicated with an air inlet pipe 28. A one-way valve 29 is installed on the air inlet pipe 28. An air outlet pipe 30 is fixedly connected to the movable frame 3. The air outlet pipe 30 is arranged towards the inner side wall of the processing box 2. The air outlet pipe 30 and the airbag 27 are communicated through a connecting pipe 31.

[0041] A connecting block 32 is fixedly connected to the outer side wall of the airbag 27. The bottom end surface of the connecting block 32 is fixedly connected to a second spring 33. The second spring 33 is fixedly connected to the upper surface of the bottom plate 1. When the loading box 10 moves downward, the airbag 27 needs to be squeezed, so that the gas in the airbag 27 enters the air outlet pipe 30. The gas is used to blow the liquid remaining on the inner side wall of the processing box 2 to facilitate its downward movement. When the loading box 10 moves upward, due to the elastic force of the second spring 33, the airbag 27 expands, so that the outside gas enters the airbag 27 through the air inlet pipe 28. At the same time, due to the setting of the one-way valve 29, only the outside gas is allowed to enter the airbag 27, and the gas in the airbag 27 is not allowed to flow to the outside through the air inlet pipe 28.

[0042] Working principle: The staff places the crude oil to be processed on the filter plate 4. The filtered oil flows into the processing tank 2 through the filter holes 9 opened on the filter plate 4. Since the crude oil contains impurities, the filter plate 4 realizes the filtration treatment of the crude oil. The impurities are located on the upper surface of the filter plate 4, preventing the uniform accumulation of impurities on the filter plate 4 and causing blockage of the filter holes 9. The second drive motor 18 works to rotate the first rotating shaft 16. At the same time, since pulley 19 is fixedly connected to both the first rotating shaft 16 and the second rotating shaft 17, the pulley 19 rotates during the rotation of the first rotating shaft 16. At the same time, the second rotating shaft 17 rotates through the belt 20. During the rotation of the first rotating shaft 16, the first rotating cylinder 5 rotates. During the rotation of the first rotating cylinder 5, the cleaning block 7 rotates. Since the end of the cleaning block 7 is in contact with the upper surface of the filter plate 4, the impurities on the upper surface of the filter plate 4 are swept to the upper left of the filter plate 4 during the rotation of the cleaning block 7. Since the crude oil is viscous, the stirring effect on the crude oil above the filter plate 4 is realized through the action of the first rotating cylinder 5 and the cleaning block 7, facilitating the flow of the crude oil.

[0043] The crude oil flowing into the processing tank 2 is refined to obtain mineral oil. At the same time, through static settlement, the sediment is located in the loading box 10. At the same time, viscous liquid impurities adhere to the side wall of the processing tank 2. The hydraulic rod 11 works to move the moving frame 3 downward through the connecting rod 12, so as to realize the movement of the moving frame 3 inside the processing tank 2. During the movement of the moving frame 3, the push block 26 acts on the stop block 24, so as to realize the movement of the stop block 24, that is, the cleaning liquid in the storage cavity 21 flows through the discharge hole 23 to the inner side wall of the processing tank 2. At the same time, the second drive motor 18 works to rotate the first rotating shaft 16. At the same time, since pulley 19 is fixedly connected to both the first rotating shaft 16 and the second rotating shaft 17, the pulley 19 rotates during the rotation of the first rotating shaft 16. At the same time, the second rotating shaft 17 rotates through the belt 20. During the rotation of the second rotating shaft 17, the second rotating cylinder 6 rotates. Since the scraping block 8 is fixedly connected to the circumferential outer wall of the second rotating cylinder 6, the scraping block 8 rotates during the rotation of the second rotating cylinder 6. At the same time, since one end of the scraping block 8 is in contact with the inner side wall of the processing tank 2, the viscous impurities adhering to the inner side wall of the processing tank 2 are scraped off and fall into the loading box 10 during the rotation of the scraping block 8. At the same time, the cleaning liquid realizes the cleaning effect on the inner side wall of the processing tank 2.

[0044] During the downward movement of the loading box 10, the airbag 27 is squeezed through the loading box 10, so that the gas in the airbag 27 enters the air outlet pipe 30. The gas blows the residual liquid on the inner side wall of the processing tank 2 to facilitate downward movement, realizing the cleaning of the inner side wall of the processing tank 2.
