Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, specifically to a petrochemical coalescing filter element that is easy to replace and install. Background Technology

[0002] Petrochemical coalescing filter elements are key filtration components used in the petrochemical industry for liquid-liquid or gas-liquid separation. They are mainly used to remove tiny water droplets from liquids or liquid droplets from gases. Their core function is to combine tiny droplets into larger droplets through the coalescing effect, and then discharge them by gravity or separation devices, thereby purifying the medium.

[0003] For example, a coalescing separator filter element with announcement number "CN218421159U" ensures that the interference of the input oil on water is minimal during use, allowing the oil to completely remove water after entering the device. However, during installation, the outer shell and the transparent bottom shell are connected by threads, which may cause difficulties in disassembly due to oil residue, making it inconvenient to disassemble, install, and replace the internal filter element. Furthermore, when filtering oils of different viscosities, the oil flow rate needs to be controlled. Utility Model Content

[0004] The purpose of this invention is to solve the problems of inconvenience in disassembling, installing, and replacing the internal filter element, and the inability to adjust the oil flow rate, and to propose a petrochemical coalescing filter element that is easy to replace and install.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A petrochemical coalescing filter element designed for easy replacement and installation includes a first housing and a rubber ring. The end of the first housing abuts against the rubber ring, and the end of the rubber ring abuts against a second housing. A fixing structure is provided on the outer side of the first housing, and a feed adjustment structure is provided on the left side of the second housing. The upper end of the first housing is fixedly connected to the output port, and the right end of the second housing is fixedly connected to the discharge pipe.

[0007] Preferably, the fixing structure includes a first collar, which is movably connected to a second collar via a hinge. A first fixing block is fixedly connected to the end of the first collar, and a second fixing block is fixedly connected to the end of the second collar. Both the first fixing block and the second fixing block are threadedly connected to bolts.

[0008] Preferably, the inner wall of the first collar abuts against the first outer shell and the second outer shell respectively, and the inner wall of the second collar abuts against the first outer shell and the second outer shell respectively.

[0009] Preferably, the feeding adjustment structure includes a feeding pipe, a motor is fixedly connected to the lower end of the feeding pipe, a rotating shaft is fixedly connected to the output end of the motor, both ends of the rotating shaft are rotatably connected to the feeding pipe through sealed bearings, and blades are fixedly connected to the outer wall of the rotating shaft.

[0010] Preferably, the end of the feed pipe is fixedly connected to the second outer casing.

[0011] Preferably, a bracket is fixedly connected to the inner wall of the second outer shell, and a mesh filter element, an inner separation filter element, and a quicklime water absorption tray are installed sequentially from bottom to top on the inner wall of the first outer shell.

[0012] The present invention proposes a petrochemical coalescing filter element that is easy to replace and install. The advantages are as follows: by fixing the structure and cooperating with the workers, the first and second rings are aligned with the positions of the first and second outer shells that abut against the rubber rings. The first and second rings are then closed, so that the ends of the first and second fixing blocks are in contact. The bolts are then rotated and inserted into the first and second fixing blocks to fix them. The feed pipe is then connected to the external oil pump, thus completing the installation of the device. This avoids oil sticking to the threads and facilitates the installation and disassembly of the device.

[0013] By cooperating with the feed adjustment structure and feed pipe, and with the external power supply of the motor, the motor is started and drives the rotating shaft to rotate. The rotating shaft drives the blades to rotate. Adjusting the position of the blades, and thus the size of the internal channel of the feed pipe, adjusts the flow rate of the oil. The flow rate of the oil can be adjusted according to the viscosity of the oil. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] See attached document Figure 1-5 :

[0022] In this embodiment, a petrochemical coalescing filter element that is easy to replace and install includes a first outer shell 1 and a rubber ring 4. The end of the first outer shell 1 abuts against the rubber ring 4, and the end of the rubber ring 4 abuts against the second outer shell 2. A fixing structure 3 is provided on the outer side of the first outer shell 1, and a feed adjustment structure 5 is provided on the left side of the second outer shell 2. The upper end of the first outer shell 1 is fixedly connected to the output port 7, and the right end of the second outer shell 2 is fixedly connected to the discharge pipe 6. A bracket 8 is fixedly connected to the inner wall of the second outer shell 2. A mesh coalescing filter element 9, an inner separation filter element 10, and a quicklime water absorption plate 11 are installed sequentially from bottom to top on the inner wall of the first outer shell 1.

[0023] See attached document Figure 1-2 And 4:

[0024] The fixing structure 3 includes a first collar 301, which is movably connected to a second collar 302 via a hinge. A first fixing block 303 is fixedly connected to the end of the first collar 301, and a second fixing block 304 is fixedly connected to the end of the second collar 302. Both the first fixing block 303 and the second fixing block 304 are threadedly connected to bolts 305. The inner wall of the first collar 301 abuts against the first outer shell 1 and the second outer shell 2, respectively. The inner wall of the second collar 302 abuts against the first outer shell 1 and the second outer shell 2, respectively.

[0025] See attached document Figure 1-3 :

[0026] The feed adjustment structure 5 includes a feed pipe 501, the end of which is fixedly connected to the second outer shell 2. A motor 502 is fixedly connected to the lower end of the feed pipe 501. A rotating shaft 503 is fixedly connected to the output end of the motor 502. Both ends of the rotating shaft 503 are rotatably connected to the feed pipe 501 through sealed bearings. A blade 504 is fixedly connected to the outer wall of the rotating shaft 503. The output shaft of the motor 501 can drive the rotating shaft 503 to rotate, and at the same time drive the blade 504 to rotate, thereby adjusting the size of the opening inside the feed pipe 501 and thus adjusting the flow rate.

[0027] Working principle:

[0028] When in operation, the mesh filter element 9, the inner separation filter element 10, and the quicklime water absorption plate 11 are sequentially installed inside the first outer shell 1, and the mesh filter element 9, the inner separation filter element 10, and the quicklime water absorption plate 11 are pressed tightly against the inner wall of the first outer shell 1.

[0029] Installation work:

[0030] Align the first outer shell 1, the second outer shell 2, and the rubber ring 4. Then align the first collar 301 and the second collar 302 with the positions of the first outer shell 1 and the second outer shell 2 that abut against the rubber ring 4. Close the first collar 301 and the second collar 302 so that the ends of the first fixing block 303 and the second fixing block 304 are in contact. Then rotate the bolt 305 into the first fixing block 303 and the second fixing block 304 to fix the first fixing block 303 and the second fixing block 304. Connect the feed pipe 501 to the external oil pump to complete the installation of the device.

[0031] Filtration process:

[0032] External oil is fed into the second housing 2 through the feed pipe 501, and the external power supply of the motor 502 is connected. The motor 502 is started, which drives the rotating shaft 503 to rotate. The rotation of the rotating shaft 503 drives the blade 504 to rotate. The position of the blade 504 is adjusted, thereby adjusting the size of the internal channel of the feed pipe 501 to regulate the flow rate of the oil. Through encoder feedback and PID control, the servo motor can be controlled to precisely rotate the target angle. After the adjustment is completed, the motor 502 is turned off. The motor 502 is a servo motor with a self-locking function, which can keep the channel size unchanged. High viscosity oil requires a low flow rate to avoid high pressure and blockage, while low viscosity oil can increase the flow rate to speed up the filtration.

[0033] The oil is filtered sequentially through the mesh filter element 9, the internal separation filter element 10, and the quicklime water absorption plate 11, and is finally discharged from the outlet 7. The mesh filter element 9 blocks small particulate impurities in the oil, and small water droplets in the oil agglomerate into larger water droplets through the mesh filter element 9, and are then guided to the second shell 2. After preliminary water removal, the oil is further removed by the internal separation filter element 10 and then guided to the quicklime water absorption plate 11, where the quicklime water absorption plate 304 further absorbs the water in the oil.

[0034] After the work is completed, stop the oil supply, rotate bolt 305 to remove bolt 305, and then you can open the device to clean the inside and replace the filter element.

[0035] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
