Description

Technical Field

[0001] This utility model belongs to the field of petroleum processing technology, and in particular to a centrifugal separation device for oil in a petroleum refining laboratory. Background Technology

[0002] Petroleum is a viscous, dark brown liquid, often referred to as the "blood of industry." It is primarily found in the upper layers of the Earth's crust. In petroleum processing, centrifugation is frequently used to remove impurities. However, current centrifugal separators often leave impurities inside after centrifugation. Furthermore, the fixed installation of these separators makes it difficult for personnel to clean these impurities, necessitating disassembly for removal. This process is not only cumbersome but also increases the workload for workers.

[0003] A Chinese patent (authorization announcement number CN218759789U) discloses a centrifugal separation device for oil drilling fluid, which "includes a processing cylinder, a sealing cap glued to the open end of the processing cylinder, a centrifugal cylinder vertically arranged inside the processing cylinder, and a motor installed at the bottom of the processing cylinder, wherein the output shaft of the motor passes through the inside of the processing cylinder and is fixedly connected to the bottom end of the centrifugal cylinder."

[0004] It is evident that the cited patent document suffers from the problem of making it inconvenient to remove impurities from inside the device. Utility Model Content

[0005] The purpose of this invention is to provide a centrifugal separation device for oil in a petroleum refining laboratory to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a centrifugal separation device for petroleum refining laboratory oil, comprising a separation cylinder, a cylinder cover on the top surface of the separation cylinder, a centrifugal cylinder for centrifugal separation in laboratory petroleum refining rotatably mounted on the inner top surface of the cylinder cover, two symmetrically arranged sliding grooves on the periphery of the centrifugal cylinder, vertical rods installed on the inner top surface of each of the two sliding grooves, a bottom block on the bottom surface of the centrifugal cylinder, two sliding rods symmetrically welded to the top surface of the bottom block, the two sliding rods slidingly sleeved on the periphery of the two vertical rods, a pad for supporting impurities installed on the top surface of the bottom block, a filter screen for filtering petroleum installed on the periphery of the centrifugal cylinder, and aligned threaded holes on the periphery of both the centrifugal cylinder and the pad, with bolts threadedly connected to the inner cavities of the two aligned threaded holes.

[0007] Preferably, a limiting groove is formed on the inner top surface of the separation cylinder, and a limiting block that is slidably adapted to the limiting groove is installed on the top surface of the centrifuge cylinder.

[0008] Preferably, the inner bottom surface of the separation cylinder is equipped with a guide block for guiding the movement of the separated oil.

[0009] Preferably, a drive motor is mounted on the inner bottom surface of the guide block, and the output end of the drive motor passes through the guide block and is connected to a turntable.

[0010] Preferably, the top surface of the turntable is provided with multiple locking blocks at equal intervals, and the bottom surface of the bottom block is provided with multiple locking slots at equal intervals to engage with the locking blocks.

[0011] Preferably, two hydraulic cylinders are symmetrically mounted on the bottom surface of the separator via a support base, and the piston rods of the two hydraulic cylinders are connected to a cross plate.

[0012] Preferably, the bottom surface of the horizontal plate is connected and fixed to the top surface of the cylinder cover, and the periphery of the separating cylinder is symmetrically connected to two pipes equipped with solenoid valves.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This petroleum refining laboratory's oil centrifugal separation equipment can move the centrifuge cylinder simultaneously by moving the cylinder cover upwards. This allows the centrifuge cylinder to be removed from the inside of the separation cylinder, and the bolts can be turned to remove the pad block fixing, thus separating the bottom block from the centrifuge cylinder and exposing the impurities for easy cleaning. Compared to existing equipment for centrifugal separation of petroleum, this device can remove the separated impurities from the centrifuge cylinder, avoiding the need for personnel to disassemble the equipment to clean the impurities, saving both time and effort.

[0015] The installed drive motor provides power for the rotation of the centrifuge drum, while the installed limit blocks and the opened limit grooves support the position of the centrifuge drum and limit its rotation. The connected pipes can discharge the centrifuged oil from the separation drum for collection and processing. Attached Figure Description

[0023] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0024] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0025] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0026] like Figures 1 to 4 The illustrated petroleum refining laboratory oil centrifugal separation device includes a separation cylinder 1, a cylinder cover 2 on the top surface of the separation cylinder 1, and a centrifugal cylinder 3 for centrifugal separation in the laboratory for petroleum refining rotatably mounted on the inner top surface of the cylinder cover 2. The top surface of the cylinder cover 2 is provided with a feed inlet, which is located directly above the centrifugal cylinder 3. The oil to be centrifuged can be fed into the centrifugal cylinder 3 through the feed inlet for centrifugal separation.

[0027] Two symmetrical grooves 4 are provided on the periphery of the centrifuge cylinder 3. Vertical rods 5 are installed on the inner top surface of each groove 4. A bottom block 6 is provided on the bottom surface of the centrifuge cylinder 3. Two sliding rods 7 are symmetrically welded to the top surface of the bottom block 6. The two sliding rods 7 are slidably fitted around the periphery of the two vertical rods 5. A pad block 8 for supporting impurities is installed on the top surface of the bottom block 6. A filter screen 9 for filtering oil is installed on the periphery of the centrifuge cylinder 3. Because the pad block 8 is adapted to the inner diameter of the centrifuge cylinder 3, when the bottom block 6 abuts against the bottom surface of the centrifuge cylinder 3, the pad block 8 will be located within the inner cavity of the centrifuge cylinder 3. A sealing strip (not shown) is installed on the periphery of the pad block 8 to improve the sealing between the pad block 8 and the centrifuge cylinder 3. When oil is fed into the centrifuge cylinder 3 through the inlet, rotating the centrifuge cylinder 3 allows the oil to pass through the filter screen 9 through centrifugal force, while impurities remain inside the centrifuge cylinder 3, thus achieving the desired oil separation. In the centrifuge separation process, after processing is complete, the cylinder cover 2 is moved upward, which in turn moves the centrifuge cylinder 3 upward, causing the bottom block 6 to move upward and be removed from the separation cylinder 1. After the bottom block 6 leaves the centrifuge cylinder 3, it moves downward. When the bottom block 6 moves downward, it causes the two sliding rods 7 to move downward, allowing the two sliding rods 7 to move downward around the two vertical rods 5 respectively. This restricts the movement trajectory of the two sliding rods 7 and the bottom block 6. When the bottom block 6 moves downward, it causes the pad block 8 to move downward. The impurities inside the centrifuge cylinder 3 will move downward with the pad block 8 due to gravity, thus allowing the impurities to be removed from the centrifuge cylinder 3 and exposed to the outside. This facilitates the cleaning of impurities and the cleaning of the separation cylinder 1 and the centrifuge cylinder 3, avoiding the need to disassemble the equipment when cleaning impurities and reducing the workload of the staff.

[0028] Both the centrifuge cylinder 3 and the pad 8 have aligned screw holes 10 on their periphery. The two aligned screw holes 10 are threaded with bolts 11. When the pad 8 enters the centrifuge cylinder 3, the screw holes 10 on the periphery of the pad 8 are aligned with the screw holes 10 on the periphery of the centrifuge cylinder 3. At this time, the bolts 11 are inserted into the two aligned screw holes 10 to fix the position of the pad 8, so that the bottom block 6 always abuts against the bottom surface of the centrifuge cylinder 3. Conversely, when the bolts 11 are removed from the screw holes 10, the pad 8 can be unsecured. At this time, the bottom block 6 and the pad 8 can move downward to remove impurities from the centrifuge cylinder 3.

[0029] A guide block 12 for guiding the movement of separated oil is installed on the inner bottom surface of the separator 1. A drive motor 13 is installed on the inner bottom surface of the guide block 12. The output end of the drive motor 13 passes through the guide block 12 and is connected to a turntable 14. Multiple locking blocks 15 are equidistantly installed on the top surface of the turntable 14. Multiple locking slots 16 that engage with the locking blocks 15 are equidistantly opened on the bottom surface of the bottom block 6. Initially, the multiple locking blocks 15 will be in the multiple locking slots 16 respectively. When it is necessary to rotate the centrifuge 3 to centrifuge and separate the oil, the drive motor 13 is turned on, driving the turntable 14 to rotate. The system can drive the bottom block 6 and the pad block 8 to rotate synchronously through the locking block 15 and the locking slot 16. Since the pad block 8 is fixed to the centrifuge cylinder 3 by the bolt 11, it can drive the centrifuge cylinder 3 to rotate and perform centrifugal separation of oil. When the cylinder cover 2 moves upward and drives the centrifuge cylinder 3 and the bottom block 6 to move upward, the multiple locking slots 16 will disengage from the multiple locking blocks 15 to achieve separation. When the cylinder cover 2 drives the centrifuge cylinder 3 and the bottom block 6 to move downward, the multiple locking slots 16 need to be aligned with the multiple locking blocks 15 and engaged in them, so that the turntable 14 can drive the centrifuge cylinder 3 to rotate again.

[0030] A limiting groove 20 is provided on the inner top surface of the separation cylinder 1, and a limiting block 21 that is slidably adapted to the limiting groove 20 is installed on the top surface of the centrifuge cylinder 3. When the centrifuge cylinder 3 rotates, it will drive the limiting block 21 to rotate in the inner cavity of the limiting groove 20, so that the limiting groove 20 and the limiting block 21 can not only support the position of the centrifuge cylinder 3 and allow the centrifuge cylinder 3 to move with the cylinder cover 2, but also assist the rotation of the centrifuge cylinder 3.

[0031] Two hydraulic cylinders 17 are symmetrically mounted on the bottom surface of the separator 1 via a support base. The piston rods of the two hydraulic cylinders 17 are connected to a horizontal plate 18. The bottom surface of the horizontal plate 18 is fixedly connected to the top surface of the cylinder cover 2. By opening the two hydraulic cylinders 17, the horizontal plate 18 can be moved upward, thereby moving the cylinder cover 2 upward, providing power for the movement of the cylinder cover 2 and the centrifuge cylinder 3. Since the top surface of the cylinder cover 2 is provided with a feed inlet, the center of the horizontal plate 18 is hollowed out, and the feed inlet is located in this hollowed-out area.

[0032] Two solenoid valves are symmetrically connected to the periphery of the separator 1. The separated oil passes through the filter screen 9 and enters the separator 1, and moves downward by gravity. At this time, the solenoid valve is opened, and the centrifugally separated oil is discharged from the separator 1 through the drain pipes 19.

[0033] Working principle:

[0034] In this petroleum refining laboratory, the oil centrifugal separation equipment operates by turning on the drive motor 13 before centrifugation. This drives the turntable 14 to rotate, and the turntable 14, through the clamping block 15 and the clamping slot 16, drives the bottom block 6 to rotate synchronously, thus rotating the centrifuge cylinder 3. At this time, the oil to be centrifuged is fed into the centrifuge cylinder 3 through the feed inlet, allowing the centrifuge cylinder 3 to centrifuge the oil. The separated oil passes through the filter screen 9, while impurities remain inside the centrifuge cylinder 3. After centrifugation is complete, the hydraulic cylinder 17 is activated, which drives the horizontal plate 18 to rotate... The cover 2 moves upward, thereby moving the centrifuge cylinder 3 upward and removing it from the separation cylinder 1. After removal, the bolt 11 is rotated to remove it from the two screw holes 10, thus releasing the fixation on the bottom block 6. At this time, the bottom block 6 is moved downward, which moves the pad block 8 downward. The impurities inside the centrifuge cylinder 3 will move downward with the pad block 8 due to gravity, thus exposing the impurities to the outside, making it convenient for personnel to clean the impurities. It also makes it convenient to clean the separation cylinder 1 and the centrifuge cylinder 3, avoiding the need to disassemble the equipment when cleaning impurities, and reducing the workload of the staff.
