Abstract

The present invention relates to the technical field of liquid filtering equipment, and in particular to a pipeline filtering device for the production of high-viscosity defoaming agents. The existing equipment has a single method for cleaning the filter screen, which easily causes too many impurities to remain on the filter screen, resulting in an insufficient filtering speed for the high-viscosity defoaming agent, and impurities will fall to one side of the discharge port when the filter screen is cleaned, which is easy to contaminate the filtered high-viscosity defoaming agent. A pipeline filtering device for the production of high-viscosity defoaming agents includes a feed rack and a fixed cylinder, etc.; the feed rack is fixedly connected to the fixed cylinder, and the feed rack is provided with a feed port. The rotation of the guide rod will drive the filter screen in channel one to swing, and the swing of the filter screen causes one side of the filter screen to break contact with the fixed frame, so that the impurities that fall on the outside of the filter screen can also be discharged through the solenoid valve on the feed rack, thereby making the filtered high-viscosity defoaming agent less likely to be contaminated by impurities.

Description

Technical Field

[0001] The invention relates to the technical field of liquid filtering equipment, in particular to a pipeline filtering device for producing high-viscosity defoaming agents. Background Art

[0002] During the production of high-viscosity defoamers, due to the debris generated during the operation of the equipment and the dust generated when the raw materials are added, there will be impurities in the produced high-viscosity defoamers. If these impurities are not removed, the use effect of the high-viscosity defoamers will be affected.

[0003] The existing pipeline filtering device filters the high-viscosity defoamer through multiple groups of filter screens. The high-viscosity defoamer requires a higher pressure to filter, and the higher pressure makes it easy for impurities to be tightly stuck in the filter holes of the filter screen. The existing device can seal each group of filter screens separately, and then clean the filter screen by backflushing. However, when the filter screen is backflushed, some impurities will be impacted to the side close to the discharge port, which is easy to contaminate the filtered high-viscosity defoamer, and long-term backflushing cleaning will also easily cause impurities to be stuck on the filter screen from another direction. Because the impurities are tightly stuck in the filter holes of the filter screen, the single cleaning method is not effective for the filter screen, which leads to excessive residual impurities on the filter screen, resulting in insufficient filtration speed for the high-viscosity defoamer. Summary of the invention

[0004] In order to overcome the shortcomings of the existing equipment that the single filter cleaning method easily leads to excessive impurities remaining on the filter, thus resulting in insufficient filtering speed for the high-viscosity defoaming agent, and impurities falling to the side of the discharge port when the filter is cleaned, which easily contaminates the filtered high-viscosity defoaming agent, the present invention provides a pipeline filtering device for the production of high-viscosity defoaming agent, which is capable of discharging impurities on the side of the discharge port and cleaning the filter by multiple cleaning methods, thereby enabling the filter to filter the high-viscosity defoaming agent faster.

[0008] Furthermore, the swing mechanism includes a guide rod, a lower pressure frame, a movable rod frame, a movable frame, a sliding column and a compression spring. Each filter is fixedly connected to a guide rod. The five guide rods on the same group of filter screens form a group. Each guide rod is provided with a guide groove. The guide grooves of the five guide rods in the same group are slidably connected with a lower pressure frame. There are two lower pressure frames in total. The two groups of guide rods and the two lower pressure frames are respectively located in two shells. Each fixed frame is slidably connected to the movable rod frame. The lower ends of the two movable rod frames are respectively fixedly connected to the movable frames. The two movable frames are respectively in contact with the two groups of filter screens.

[0009] Furthermore, the reciprocating mechanism includes a reciprocating screw, a threaded guide block, a rotating disk and a contact rod.

[0010] Furthermore, it also includes a scraping mechanism, which is arranged on the filter screen and is used to scrape impurities on the filter screen. The scraping mechanism includes a pushing frame, a fixed rod and a scraper frame. Each threaded guide block is fixedly connected to the pushing frame, each filter screen is fixedly connected to the fixed rod, and each fixed rod is slidably connected to a scraper frame.

[0012] Furthermore, a knocking block is included, and each movable rod frame is fixedly connected with the knocking block.

[0013] The present invention has the following advantages: 1. The rotation of the guide rod will drive the filter screen in channel 1 to swing. The swing of the filter screen causes one side of the filter screen to break away from the fixed frame, so that impurities falling on the outside of the filter screen can also be discharged through the solenoid valve on the feed frame, thereby making the filtered high-viscosity defoaming agent less likely to be contaminated by impurities.

[0014] 2. When the filter screen is completely fitted with the fixing frame, the high-viscosity defoaming agent will backwash the filter screen, and the impurities on the filter screen will be impacted by the high-viscosity defoaming agent. When one side of the filter screen is out of contact with the fixing frame, the high-viscosity defoaming agent will directly flow away from the gap between the filter screen and the fixing frame. The high-viscosity defoaming agent will no longer impact the impurities on the filter screen. The constantly swinging filter screen will cause the filter screen to continuously switch between the two states, allowing the impurities on the filter screen to fall off better, thereby improving the cleaning effect of the filter screen, so that the filters in channel one and channel two can filter the high-viscosity defoaming agent faster.

[0015] 3. The scraper frame moves downward to scrape the impurities on the filter, loosening the impurities stuck on the filter and causing the impurities to fall from both sides of the filter. When one side of the filter is detached from the fixing frame, the recoil high-viscosity defoaming agent will take away the fallen impurities. When the filter is completely fitted with the fixing frame, the recoil high-viscosity defoaming agent will impact the loose impurities on the filter, causing the impurities to fall off the filter, thereby making the filter cleaner and enabling the filter to filter the high-viscosity defoaming agent faster.

[0016] 4. The rotation of the rotating disk will cause the moving rod frame and the moving frame to move upward through the contact rod. The rotating disk will continue to rotate and will lose contact with the contact rod. The moving rod frame and the moving frame will move downward rapidly driven by the compression spring. The rapid downward movement of the moving frame will knock on the fixed block, causing the fixed block and the filter to vibrate. At the same time, as the sliding column continues to move downward, the compression spring will continue to compress. When the sliding column moves downward, the knocking force of the knocking rod on the fixed block continues to increase, causing the fixed block and the filter to vibrate more, thereby allowing the impurities on the filter to fall off better, thereby making the filter more efficient for filtering high-viscosity defoaming agents.

[0034] The swing mechanism includes a guide rod 71, a lower pressure frame 72, a mobile rod frame 73, a mobile frame 731, a sliding column 74 and a compression spring 75. Each filter screen 52 is fixedly connected to a guide rod 71. The five guide rods 71 ​​on the same group of filter screens 52 form a group. Each guide rod 71 is provided with a guide groove. The guide grooves of the five guide rods 71 ​​in the same group are slidably connected with a lower pressure frame 72. The lower pressure frame 72 is used to drive the guide rod 71 and the filter screen 52 to swing. There are two lower pressure frames 72. The two groups of guide rods 71 ​​and the two lower pressure frames 72 are respectively located in the two housings 4. Each fixed frame 51 is slidably connected to the mobile rod frame 73. The lower ends of the two mobile rod frames 73 are respectively welded with mobile frames 731. The two mobile frames 731 are respectively in contact with the two groups of filter screens 52. Each mobile rod frame 73 is slidably connected to a sliding column 74. Compression springs 75 are connected between the two sliding columns 74 and the two mobile rod frames 73.

[0035] The reciprocating mechanism includes a reciprocating screw rod 81, a threaded guide block 82, a rotating disk 83 and a contact rod 84. Two reciprocating screw rods 81 are rotatably connected to the feed frame 1. The two reciprocating screw rods 81 are respectively fixedly connected to the rotating shafts of the two drive motors 42. Each reciprocating screw rod 81 is threadedly connected to a threaded guide block 82. The two threaded guide blocks 82 are respectively fixedly connected to the two sliding columns 74.

The two lower pressure frames 72 are respectively fixedly connected with contact rods 84. The two rotating disks 83 and the two contact rods 84 are respectively located in the two shells 4.

[0036] At first, there is continuous pressure to feed the high-viscosity defoamer into the feed rack 1 from the feed port of the feed rack 1, and then the pressure will push the high-viscosity defoamer to pass through the two channels of the fixed cylinder 2. When the high-viscosity defoamer passes through the two channels of the fixed cylinder 2, it will be filtered by the filter screens 52 on the two fixed racks 51. The filter screens 52 intercept the impurities in the high-viscosity defoamer and make the clean high-viscosity defoamer flow to the discharge rack 3. Finally, the clean high-viscosity defoamer flows out from the discharge port of the discharge rack 3, and the movable rack 731 contacts the lower end of the filter screen 52, so that the filter screen 52 is more stable when filtering the high-viscosity defoamer. After a period of filtration, the staff first starts the two electric push rods 62 near the channel 1 21, and the extension of the telescopic rod of one of the electric push rods 62 will drive the upper density The sealing plate 63 moves downward, and the extension rod of the other electric push rod 62 drives the lower sealing plate 64 to move upward. The upper sealing plate 63 moves downward and contacts the top of the channel 1 21, and the upper sealing plate 63 seals the top of the channel 1 21. The lower sealing plate 64 moves upward and contacts the bottom of the channel 1 21, and the lower sealing plate 64 seals the bottom of the channel 1 21. The upper sealing plate 63 and the lower sealing plate 64 completely seal the channel 1 21, so that the high-viscosity defoaming agent entering from the feed port of the feed rack 1 can only pass through the channel 2 22, and the filter screen 52 in the channel 2 22 filters the high-viscosity defoaming agent; then the staff closes the two electric push rods 62, and then the staff starts the two solenoid valves 53 and the drive motor 42 near the channel 1 21. After the solenoid valve 53 on the discharge rack 3 is started, clean high-viscosity defoaming agent will continuously enter the channel 21. The high-viscosity defoaming agent entering the channel 21 will flush the filter screen 52 of the channel 21 in the opposite direction, so that the impurities on the filter screen 52 are pushed and then fall off, and the high-viscosity defoaming agent will drive the impurities to be discharged from the solenoid valve 53 on the feed rack 1; the output shaft of the drive motor 42 drives a reciprocating screw rod 81 to rotate, and the rotation of the reciprocating screw rod 81 will squeeze the threaded guide block 82 through the thread, so that the threaded guide block 82 moves back and forth up and down, and the threaded guide block 82 moves downward to drive the sliding column 74 to move downward, and the sliding column 74 moves downward to drive the moving rod frame 73, the lower pressure frame 72 and the contact rod 84 to move downward through the compression spring 75, and the moving rod frame 73 moves downward The movement will drive the movable frame 731 to move downward, and the movable frame 731 will no longer contact the filter screen 52 when it moves downward. The contact rod 84 will contact the rotating disk 83 when it moves downward. The movable rod frame 73 will be restricted by the fixed frame 51 when it moves downward, so that the movable rod frame 73 stops moving. The lower pressing frame 72 moves downward first along the guide groove of the guide rod 71. The lower pressing frame 72 continues to move downward to squeeze the guide groove of the guide rod 71 and make the guide rod 71 rotate. The rotation of the guide rod 71 will drive the filter screen 52 in the channel 1 21 to swing. The swing of the filter screen 52 makes one side of the filter screen 52 disengage from the fixed frame 51, so that the impurities dropped on the outside of the filter screen 52 can also be discharged through the solenoid valve 53 on the feeding frame 1, thereby making the filtered high-viscosity defoaming agent not easily contaminated by impurities.The threaded guide block 82 will continue to drive the sliding column 74 to move downward, so that the compression spring 75 is further compressed. At the same time, the rotation of the reciprocating screw rod 81 will drive the rotating disk 83 to rotate. The rotation of the rotating disk 83 will make the inclined surface of the rotating disk 83 contact the contact rod 84. The rotating disk 83 continues to rotate to squeeze the contact rod 84 to move upward. The upward movement of the contact rod 84 will drive the lower pressure frame 72 and the moving rod frame 73 to move upward. The upward movement of the moving rod frame 73 will drive the moving frame 731 to move a short distance upward. The moving frame 731 will not contact the filter screen 52. The upward movement of the moving rod frame 73 further compresses the compression spring 75. The upward movement of the lower pressure frame 72 will squeeze the guide groove of the guide rod 71 and reset the guide rod 71. The reset of the guide rod 71 will drive the filter screen 52 to reset. The rotating disk 83 continues to rotate and disengages from the contact rod 84, and the compression spring 75 drives the lower pressure frame 72, the movable rod frame 73 and the contact rod 84 to move downward. The downward movement of the lower pressure frame 72 causes the guide rod 71 and the filter screen 52 to swing, and the contact rod 84 moves downward to contact the rotating disk 83 again, and then repeats this process again, causing the filter screen 52 to continuously swing in the high-viscosity defoaming agent. When the filter screen 52 is completely fitted with the fixed frame 51, the high-viscosity defoaming agent will backwash the filter screen 52, and the impurities on the filter screen 52 will be impacted by the high-viscosity defoaming agent. When one side of the filter screen 52 is disengaged from the fixed frame 51, the high-viscosity defoaming agent will directly flow away from the gap between the filter screen 52 and the fixed frame 51, and the high-viscosity defoaming agent will no longer impact the impurities on the filter screen 52, and the continuously swinging filter screen 52 will be smooth. The net 52 will cause the filter screen 52 to switch between the two states continuously, so that the impurities on the filter screen 52 can fall off better, thereby making the cleaning effect of the filter screen 52 better, so that the filter screens 52 in the channel 1 21 and the channel 2 22 can filter the high-viscosity defoaming agent faster, and the impurities falling from the filter screen 52 will be discharged from the one-way valve on the feed rack 1, and the threaded guide block 82 will drive the sliding column 74 to move upward, and the sliding column 74 moves upward to reset the compression spring 75, and the sliding column 74 continues to move upward to drive the moving rod frame 73, the lower pressure frame 72 and the contact rod 84 to move upward through the compression spring 75, and the contact rod 84 moves upward to disengage from the rotating disk 83, and the reset of the moving rod frame 73 will drive the moving frame 731 to reset upward, and the lower pressure frame The upward movement of 72 will squeeze the guide groove of the guide rod 71 so that the guide rod 71 rotates and resets. The rotation and reset of the guide rod 71 will drive the filter screen 52 to reset. After the filter screen 52 is reset, the moving rod frame 73 continues to drive the moving frame 731 and the lower pressure frame 72 to reset upward. The moving frame 731 contacts the filter screen 52 again. The lower pressure frame 72 continues to move upward to move the guide groove of the guide rod 71. After the reset is completed, the staff closes the two solenoid valves 53 and the drive motor 42 near the channel 1 21. After the two solenoid valves 53 are closed, no high-viscosity defoaming agent enters and flows out through the solenoid valves 53. Then the staff restarts the two electric push rods 62 near the channel 1 21. The telescopic rods of the two electric push rods 62 will drive the upper sealing plate 63 and the lower sealing plate 64 to reset.The upper sealing plate 63 and the lower sealing plate 64 are reset to make the channel 1 21 no longer sealed, so that the high-viscosity defoaming agent passes through the channel 1 21 and the filter screen 52 in the channel 1 21 again. The staff closes the two electric push rods 62 near the channel 1 21. Finally, the staff starts the two electric push rods 62 near the channel 2 22. The telescopic rods of the two electric push rods 62 drive the upper sealing plate 63 and the lower sealing plate 64 to seal the channel 2 22, so that the high-viscosity defoaming agent entering from the feed port can only pass through the channel 1 21. The filter screen 52 in the channel 1 21 filters the high-viscosity defoaming agent. The filter screens 52 in the channel 1 21 and the channel 2 22 are cleaned without affecting the filtration of the high-viscosity defoaming agent. The staff closes the two electric push rods 6 near the channel 2 22. 2 and start the two solenoid valves 53 and the drive motor 42 near the second channel 22. The drive motor 42 will drive the reciprocating screw 81, the guide rod 71, the lower pressure frame 72, the mobile rod frame 73, the sliding column 74, the compression spring 75, the threaded guide block 82, the rotating disk 83 and the contact rod 84. After the above steps are completed, the staff closes the two solenoid valves 53 and the drive motor 42 near the second channel 22 and starts the telescopic rods of the two electric push rods 62 near the second channel 22 to drive the upper sealing plate 63 and the lower sealing plate 64 to reset. The upper sealing plate 63 and the lower sealing plate 64 are reset so that the second channel 22 is no longer sealed. Finally, the staff closes the two electric push rods 62 near the second channel 22, so that the impurities on the filter screen 52 in the second channel 22 are discharged through the solenoid valve 53. And the filter screens 52 in the first channel 21 and the second channel 22 are cleaned without affecting the filtration of the high-viscosity defoaming agent. ,

The five fixing rods 92 and the five scraper frames 93 on the same group of filter screens 52 form a group, and each group of scraper frames 93 is in contact with one pushing frame 91.

[0038] The swing of the filter screen 52 will drive the fixing rod 92 and the scraper frame 93 to swing, the downward movement of the threaded guide block 82 will drive the pushing frame 91 to move downward, and the downward movement of the pushing frame 91 will drive the scraper frame 93 to move downward, and the downward movement of the scraper frame 93 will scrape the impurities on the filter screen 52, loosening the impurities stuck on the filter screen 52, causing the impurities to fall from both sides of the filter screen 52, and when one side of the filter screen 52 is separated from the fixing frame 51, the recoil high-viscosity defoaming agent will take away the fallen impurities, and when the filter screen 52 is completely fitted with the fixing frame 51, the recoil high-viscosity defoaming agent will impact the loose impurities on the filter screen 52, causing the impurities to detach from the filter screen 52, thereby making the filter screen 52 cleaner, so that the filter screen 52 can filter the high-viscosity defoaming agent faster, and when the scraper frame 93 moves downward to the bottom of the filter screen 52, the threaded guide block 82 will reset upward, which will drive the pushing frame 91 to reset upward, and the pushing frame 91 will reset upward, which will drive the scraper frame 93 to reset upward.

Five limiting blocks 103 are fixedly connected to each fixed frame 51, and there are ten limiting blocks 103 in total. The ten limiting blocks 103 are slidably connected to the ten knocking rods 101 respectively.

[0040] The downward movement of the movable frame 731 will drive the knocking rod 101 to move downward, and the knocking rod 101 will contact the fixed block 102 when it moves downward, and the filter screen 52 will drive the fixed block 102 to swing, and the rotation of the rotating disk 83 will cause the movable rod frame 73 and the movable frame 731 to move upward through the contact rod 84, and the movable frame 731 will move upward to compress the compression spring 75, and the rotating disk 83 will continue to rotate to disengage from the contact rod 84, and the movable rod frame 73 and the movable frame 731 will move downward quickly driven by the compression spring 75, and the movable frame 731 will move downward quickly. The frame 731 moves downward quickly and hits the fixed block 102, causing the fixed block 102 and the filter screen 52 to vibrate, and then repeats this process. At the same time, as the sliding column 74 continues to move downward, the compression spring 75 will continue to be compressed. When the sliding column 74 moves downward, the knocking force of the knocking rod 101 on the fixed block 102 continues to increase, causing the fixed block 102 and the filter screen 52 to vibrate more, thereby allowing the impurities on the filter screen 52 to fall off better, thereby making the filter screen 52 more efficient in filtering high-viscosity defoaming agents.

[0041] Embodiment 4: Based on the embodiment 3, Figure 5As shown, a knocking block 11 is also included, and each movable rod frame 73 is fixedly connected to the knocking block 11.

[0042] The movement of the movable rod frame 73 will drive the knocking block 11 to move, and the rapid downward movement of the movable rod frame 73 will drive the knocking block 11 to knock the fixed frame 51, so that the impurities remaining on the fixed frame 51 can be vibrated and then discharged by the high-viscosity defoaming agent through the solenoid valve 53.
