Description

Technical Field

[0001] The invention belongs to the technical field of petroleum refining, and in particular relates to a naphtha raw material filter. Background Art

[0002] Naphtha is an important petroleum refining product, widely used in chemical raw materials, solvents and fuels. In the production and processing of naphtha, the purity of the raw materials directly affects the quality and performance of the final product. Therefore, it is very important to effectively filter the naphtha raw materials and remove impurities and particulate matter.

[0003] In the use of the prior art (Announcement No. CN112057942B, Patent Name: A Patent Application for a Cross-flow Ceramic Membrane Filter in the Field of Petrochemical Industry), petroleum flows into the feed box through the inlet pipe, and then is discharged into the filter box through connecting pipe 1 and connecting pipe 2. The petroleum flowing into the feed box through connecting pipe 1 contacts the ceramic membrane for dead-end filtration, and the petroleum flowing into the feed box through connecting pipe 2 contacts the ceramic membrane for cross-flow filtration. When filter cakes accumulate on the surface of the ceramic membrane, the flow rate of petroleum flowing to the installation shell through connecting pipe 3 is slow, and the amount of petroleum flowing to the filter box through connecting pipe 2 increases, and the dead-end filtration is converted to cross-flow filtration. The petroleum impacts the filter cake on the surface of the ceramic membrane, so that the filter cake enters the impurity removal box through the connecting frame, and then is removed by the impurity removal box, thereby improving the chemical production efficiency of petroleum. In the process of implementing the technical solution, it is found that there are at least the following problems in the prior art.

[0004] The existing device uses a filter to filter during the filtration process to separate the solid impurities therein. When the petrochemical pipeline is transporting liquid, the liquid pressure in the pipeline increases, which in turn causes the internal pressure of the filter to increase. Since the filtered impurities adhere to the inner wall of the filter, the liquid flow resistance increases. When the liquid pressure increases instantaneously, the pressure on both sides of the filter cannot be instantly balanced, so that the filter is instantly subjected to a violent impact of the liquid, causing the shape of the filter body and the shape of the filter holes thereon to be deformed by the impact, thereby reducing the filtering effect of solid particles in the liquid. The filter needs to be replaced frequently from time to time, and the machine needs to be shut down for cleaning, which wastes time and greatly reduces the filtration efficiency.

[0017] A naphtha raw material filter of the present invention:

[0018] 1. For the naphtha raw material filter, the staff connects the T-shaped liquid inlet pipe to the naphtha delivery pipeline. In the initial state, the plugging valve core on the left is in the open state, and the plugging valve core on the right is in the closed state. The naphtha enters the primary filter tank body on the left along the T-shaped liquid inlet pipe. After passing through the primary filter screen on the left, the naphtha is discharged from the T-shaped liquid outlet pipe. The primary filter screen performs the initial filtration of impurities in the naphtha. During the flow of naphtha, the pressure gauge can observe the pressure changes in the primary filter tank body. As the primary filter screen gradually filters the impurities in the naphtha, the impurities in the primary filter screen increase, and the resistance of the naphtha passing through the primary filter screen increases, thereby increasing the pressure on the upper part of the primary filter screen. The naphtha pressure increases. When the internal pressure of the primary filter tank on the left is too high, the servo motor drives the rotating rod and the rotating plate to rotate. The rotating plate drives the slider to enter the U-shaped groove plate. The slider pushes the U-shaped groove plate and the rotating frame to rotate. After the rotating frame drives the sealing rotating rod and the sealing valve core to rotate, the right sealing valve core is opened and the left sealing valve core is closed. The staff takes out the primary filter on the left for cleaning. After the primary filter is cleaned, the primary filter is put into the primary filter tank again. By switching the sealing valve cores on the left and right sides, the pressure in the primary filter tank is avoided to increase due to blockage of the sealing valve core, which causes the primary filter to deform, thereby increasing the service life of the primary filter.

[0019] 2. In the process of the naphtha raw material filter driven by the servo motor to rotate the rotating rod, the rotating rod drives the belt to move through the pulley, the belt drives the rotating shaft and the active card gear to rotate, the active card gear drives the driven card gear and the primary filter to rotate, so that the naphtha and the primary filter are in contact more evenly, avoiding local excessive load and improving the overall processing effect. Because the L-shaped lifting rod moves along the reciprocating groove, when the rotating shaft drives the guide circular plate to rotate, the L-shaped lifting rod is reciprocated and lifted, and the L-shaped lifting rod drives the collision ball to collide with the primary filter. The vibration generated by the primary filter helps to remove impurities blocking its filter holes, thereby reducing the maintenance frequency.

[0020] 3. The naphtha raw material filter, after primary filtration, the naphtha is discharged from the T-shaped liquid outlet pipe into the filter box, the liquid outlet pipe sucks out the naphtha in the connection box and the filter box, and the ceramic filter tube performs secondary filtration on the naphtha after primary filtration to ensure the removal of fine particles and impurities, improve the purity of the naphtha raw material, gradually remove impurities of different particle sizes, reduce the burden of single-stage filtration, and reduce liquid flow resistance. In the secondary filtration process, when the rotating rod drives the rotating circular plate and the connecting shaft to rotate, the connecting shaft can drive the T-shaped reciprocating plate to reciprocate, and the T-shaped reciprocating plate drives the reciprocating tooth plate to move. Because the reciprocating tooth plate is meshed with the driven gear, the driven gear can drive the ceramic filter tube to rotate, thereby improving the removal efficiency of impurities attached to the surface of the ceramic filter tube.

[0021] 4. In the naphtha raw material filter, the connecting rod drives the active bevel gear to rotate, the active bevel gear drives the driven bevel gear and the connecting column to rotate, the connecting column drives the teardrop-shaped top block to rotate, the teardrop-shaped top block pushes the U-shaped plate and the lifting member to rise, the lifting member drives the ceramic filter tube to rise, when the teardrop-shaped top block is separated from the U-shaped plate during rotation, the reset spring pushes the reset plate to reset, and the reset plate pushes the ceramic filter tube to descend, when filter cakes are accumulated on the surface of the ceramic filter tube, the reciprocating lifting of the ceramic filter tube causes the oil to impact the filter cakes on its surface, thereby separating the filter cakes from the ceramic filter tube, reducing the maintenance frequency, ensuring production continuity, and improving the chemical production efficiency of petroleum.

[0022] 5. The naphtha raw material filter, the T-shaped reciprocating plate drives the L-shaped push rod to reciprocate, the L-shaped push rod drives the extrusion circular plate to squeeze the gas in the air inlet cylinder, the extruded gas is discharged from the aeration hole through the aeration pipe, the discharged gas flushes the ceramic filter tube, and tiny bubbles can be generated during the aeration process. These bubbles can attach to the suspended particles and make them float to the liquid surface, preventing impurities from settling, and facilitating the slag discharge mechanism to transport impurities.

[0053] like Fig.13 and Fig.14As shown, after long-term operation, the ceramic filter tube 511 may become hardened, thereby affecting the filtration efficiency. When there are too many impurities in the filter box 51, they will settle inside, which is not conducive to the transportation of impurities, affecting the filtration effect and the long-term operation of the equipment. The bottom of the T-shaped reciprocating plate 503 is provided with an aeration mechanism 8, and the aeration mechanism 8 includes an L-shaped push rod 801 fixedly connected to the bottom of the T-shaped reciprocating plate 503, and the outer wall of the L-shaped push rod 801 is provided with an air inlet hole 802.

[0054] A working principle of a naphtha raw material filter: when in use, the staff connects the T-shaped liquid inlet pipe 17 to the naphtha delivery pipeline. In the initial state, the plugging valve core 22 on the left is in the open state, and the plugging valve core 22 on the right is in the closed state. The naphtha enters the primary filter tank body 103 on the left along the T-shaped liquid inlet pipe 17. After passing through the primary filter screen 16 on the left, the naphtha is discharged from the T-shaped liquid outlet pipe 18. The primary filter screen 16 performs the initial filtration of impurities in the naphtha. During the flow of naphtha, the pressure gauge 104 can observe the pressure change in the primary filter tank body 103. As the primary filter screen 16 gradually filters the impurities in the naphtha, the impurities in the primary filter screen 16 increase, and the resistance of naphtha passing through the primary filter screen 16 increases, thereby increasing the naphtha pressure on the upper part of the primary filter screen 16. When the internal pressure of the primary filter tank body 103 on the left is too high, the servo motor 202 drives the rotating rod 203 and the rotating plate 204 The rotating plate 204 drives the slider 205 to enter the U-shaped groove plate 24, and the slider 205 pushes the U-shaped groove plate 24 and the rotating frame 23 to rotate. After the rotating frame 23 drives the plugging rotating rod 21 and the plugging valve core 22 to rotate, the right plugging valve core 22 is opened and the left plugging valve core 22 is closed. The staff takes out the primary filter screen 16 on the left side for cleaning. After the primary filter screen 16 is cleaned, the primary filter screen 16 is put into the primary filter tank body 103 again. By switching the plugging valve cores 22 on the left and right sides, it is avoided that the plugging valve core 22 is blocked and the pressure in the primary filter tank body 103 increases, causing the primary filter screen 16 to deform, thereby increasing the service life of the primary filter screen 16. When the plugging valve core 22 on one side is closed, the solenoid valve 28 is opened, and the water pump 26 sucks out the internal naphtha of the closed primary filter tank body 103 through the suction pipe 27 to prevent the naphtha residue in the primary filter tank body 103 from being unfavorable for taking out the primary filter screen 16.

[0055] When the servo motor 202 drives the rotating rod 203 to rotate, the rotating rod 203 drives the belt 302 to move through the pulley 301, and the belt 302 drives the rotating shaft 304 and the active card gear 305 to rotate, and the active card gear 305 drives the driven card gear 306 and the primary filter screen 16 to rotate, so that the naphtha and the primary filter screen 16 are in more uniform contact, avoiding local excessive load and improving the overall processing effect. Because the L-shaped lifting rod 403 moves along the reciprocating groove 402, when the rotating shaft 304 drives the guide circular plate 401 to rotate, the L-shaped lifting rod 403 is reciprocated and lifted, and the L-shaped lifting rod 403 drives the collision ball 405 to collide with the primary filter screen 16. The vibration generated by the primary filter screen 16 helps to remove impurities blocking its filter holes, thereby reducing the maintenance frequency;

[0056] The naphtha after primary filtration is discharged from the T-shaped liquid outlet pipe 18 into the filter box 51. The liquid outlet pipe 53 sucks out the naphtha inside the connection box 52 and the filter box 51. The ceramic filter tube 511 performs secondary filtration on the naphtha after primary filtration to ensure the removal of fine particles and impurities, improve the purity of the naphtha raw material, gradually remove impurities of different particle sizes, reduce the burden of single-stage filtration, and reduce the resistance to liquid circulation. During the secondary filtration process, when the rotating rod 203 drives the rotating circular plate 501 and the connecting shaft 502 to rotate, the connecting shaft 502 can drive the T-shaped reciprocating plate 503 to reciprocate, and the T-shaped reciprocating plate 503 drives the reciprocating tooth plate 507 to move. Because the reciprocating tooth plate 507 is meshed with the driven gear 508, the driven gear 508 can drive the ceramic filter tube 511 to rotate, thereby improving the efficiency of removing impurities attached to the surface of the ceramic filter tube 511.

[0057] The driving motor 601 drives the connecting rod 602 to rotate, and the connecting rod 602 drives the conveyor belt 603 to transport the impurities suspended in the liquid to the slag box 604, and collects the impurities through the collecting box 605 to prevent the impurities from accumulating in the filter box 51. The connecting rod 602 drives the active bevel gear 701 to rotate, and the active bevel gear 701 drives the driven bevel gear 702 and the connecting column 703 to rotate. The connecting column 703 drives the teardrop-shaped top block 704 to rotate, and the teardrop-shaped top block 704 pushes the U-shaped plate 705 and the lifting member 706 to rotate. The lifting member 706 drives the ceramic filter tube 511 to rise. When the teardrop-shaped top block 704 is separated from the U-shaped plate 705 during rotation, the reset spring 707 pushes the reset plate 708 to reset. The reset plate 708 pushes the ceramic filter tube 511 to descend. When filter cakes are accumulated on the surface of the ceramic filter tube 511, the reciprocating lifting of the ceramic filter tube 511 causes the oil to impact the filter cakes on its surface, thereby separating the filter cakes from the ceramic filter tube 511, reducing the maintenance frequency, ensuring production continuity, and improving the chemical production efficiency of oil.

[0058] The T-shaped reciprocating plate 503 drives the L-shaped push rod 801 to perform reciprocating motion, and the L-shaped push rod 801 drives the extrusion circular plate 803 to squeeze the gas in the air inlet cylinder 807. The extruded gas is discharged from the aeration hole 810 through the aeration pipe 808. The discharged gas flushes the ceramic filter tube 511. Tiny bubbles can be generated during the aeration process. These bubbles can attach to the suspended particles, causing them to float to the liquid surface to prevent impurities from settling, making it easier for the slag discharge mechanism 6 to transport impurities. When the extrusion circular plate 803 is reset after the extrusion is completed, due to the restriction of the one-way valve 809, the gas can only enter the interior of the air inlet cylinder 807 through the air inlet hole 802. When the extrusion circular plate 803 is extruding, the connecting spring 805 pulls the blocking circular plate 806 and the extrusion circular plate 803 into close contact to prevent the gas in the air inlet cylinder 807 from leaking.
