Description
Technical Field

[0003] Patent CN118384576A discloses an anti-clogging pipeline filter that requires no additional power source, has a simple structure, and good impurity removal effect. However, in actual use, although impurities can be cleaned off the filter screen, the cleaned impurities will remain in the space between the guide plate and the filter plate. When there are few impurities in the space, it will not affect the use of the filter screen. However, during use, the impurities in the space will increase.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figure 1 - Figure 2 As shown, a filter anti-clogging device includes a material main pipe 1 for adding fluid materials.
[0030] The material main pipe 1 is connected to a steam main pipe 16 in the middle. The steam main pipe 16 is used to introduce steam into the device to heat the fluid material.
[0031] The steam main pipe 16 is connected to a third pneumatic valve 42 at one end corresponding to the material main pipe 1. The third pneumatic valve 42 is used to control the flow rate and pressure of steam.
[0032] The material main pipe 1 is connected to the first filter 2 and the second filter 21 on both sides of the steam main pipe 16 via flanges. The first filter 2 and the second filter 21 are used to remove impurities from the fluid material in the material main pipe 1 to ensure the sterility and safety of the fluid material.
[0033] The material main pipe 1 is connected to a first pressure sensor 3 and a second pressure sensor 31 at its two ends corresponding to the first filter 2. The first pressure sensor 3 and the second pressure sensor 31 are used to monitor the pressure changes at the two ends of the material main pipe 1 corresponding to the first filter 2.
[0034] The material main pipe 1 is connected to a third pressure sensor 32 and a fourth pressure sensor 33 at its two ends corresponding to the second filter 21. The third pressure sensor 32 and the fourth pressure sensor 33 are used to monitor the pressure changes at both ends of the material main pipe 1 corresponding to the second filter 21.
[0035] In practical use, after the fluid material enters the material main pipe 1, the pressure data at both ends of the first filter 2 can be obtained by observing the pressure values of the first pressure sensor 3 and the second pressure sensor 31. The pressure data at both ends of the second filter 21 can be obtained by observing the pressure values of the third pressure sensor 32 and the fourth pressure sensor 33. The internal condition of the first filter 2 and the second filter 21 can be determined by the pressure data, so that cleaning measures can be taken in time to prevent the first filter 2 and the second filter 21 from becoming clogged. This will not affect the normal flow of the fluid material or the cleaning efficiency.
[0036] Below the main material pipe 1, there are a first branch pipe 12, a second branch pipe 13, a third branch pipe 14 and a fourth branch pipe 15 respectively. The first branch pipe 12, the second branch pipe 13, the third branch pipe 14 and the fourth branch pipe 15 are all used to add the filtered fluid material into the discharge main pipe 11.
[0037] The lower ends of the first branch pipe 12, the second branch pipe 13, the third branch pipe 14 and the fourth branch pipe 15 are all connected to the discharge main pipe 11, which is used to discharge the filtered fluid material.
[0038] The first branch pipe 12 is located between the first pressure sensor 3 and the first filter 2. The first filter 2 and the first branch pipe 12 are connected by the first diversion pipe 5. The filtered fluid material can be sent into the first branch pipe 12 through the first diversion pipe 5.
[0039] The upper end flange of the first branch pipe 12 is connected to a first drain valve 121, which is used to drain the condensate formed after the steam in the first branch pipe 12 is condensed.
[0040] A first exhaust valve 6 is connected above the first diversion pipe 5. Before the material pipeline is used, the first exhaust valve 6 is used to release the air in the front end of the material pipeline to ensure that only the required gas is in the material pipeline.
[0041] The second branch pipe 13 is located between the second pressure sensor 31 and the steam main pipe 16. The upper end of the second branch pipe 13 is connected to the material main pipe 1. The second branch pipe 13 can directly send the filtered fluid material into the discharge main pipe 11.
[0042] A second drain valve 131 is connected to the flange above the second branch pipe 13. The second drain valve 131 is used to drain the condensate formed after the steam in the second branch pipe 13 is condensed.
[0043] The first temperature sensor 7 is connected to the lower part of the second branch pipe 13. The first temperature sensor 7 is used to measure the temperature at the front end of the device in real time.
[0044] A first pneumatic valve 4 is connected above the material main pipe 1. The first pneumatic valve 4 is located between the second branch pipe 13 and the steam main pipe 16. The first pneumatic valve 4 is used to control the flow rate of the fluid material.
[0045] The third branch pipe 14 is located between the third pressure sensor 32 and the second filter 21. The second filter 21 and the third branch pipe 14 are connected through the second diversion pipe 51. The filtered fluid material can be sent into the first branch pipe 12 through the second diversion pipe 51.
[0046] The upper flange of the third branch pipe 14 is connected to a third drain valve 141, which is used to drain the condensate formed after the steam in the third branch pipe 14 is condensed.
[0047] A second exhaust valve 61 is connected above the second diversion pipe 51. Before the material pipeline is used, the second exhaust valve 61 is used to release the air in the rear end of the material pipeline to ensure that only the required gas is in the material pipeline.
[0048] It is worth noting here that the cooperation of the first exhaust valve 6 and the second exhaust valve 61 can quickly expel the air from the material main pipe 1, thereby improving efficiency when expelling air.
[0049] The fourth branch pipe 15 is located at the end of the fourth pressure sensor 33 that is far away from the second filter 21. The fourth branch pipe 15 can directly send the filtered fluid material into the discharge main pipe 11.
[0050] The upper flange of the fourth branch pipe 15 is connected to a fourth drain valve 151, which is used to drain the condensate formed after the steam in the fourth branch pipe 15 is condensed.
[0051] It is worth noting here that the first drain valve 121, the second drain valve 131, the third drain valve 141 and the fourth drain valve 151 work together to drain condensate from different areas, thereby preventing condensate from affecting the effective utilization of steam and ensuring that the device can operate normally.
[0052] A second temperature sensor 71 is connected below the fourth branch pipe 15. The second temperature sensor 71 is used to measure the temperature at the back end of the device in real time.
[0053] A second pneumatic valve 41 is connected above the main material pipe 1. The second pneumatic valve 41 is located on the side of the fourth branch pipe 15 away from the fourth pressure sensor 33. The second pneumatic valve 41 is used to control the flow rate of the fluid material.
[0054] In practical use, the overall temperature of the device can be measured in real time through the cooperation of the first temperature sensor 7 and the second temperature sensor 71. The first temperature sensor 7 and the second temperature sensor 71 transmit the measured data to the third pneumatic valve 42. After judging the data, the third pneumatic valve 42 controls the flow of steam to keep the temperature of the device within the required range.
[0055] Working principle:
[0056] Fluid material is introduced through the front end of the material main pipe 1, and steam is introduced through the steam main pipe 16. The first pressure sensor 3 monitors the internal pressure of the material main pipe 1 at the end corresponding to the first filter 2 in real time. After flowing through the first pressure sensor 3, the fluid material enters the first filter 2 for filtration. Part of the filtered fluid material flows from the first diversion pipe 5 into the first branch pipe 12 and then into the discharge main pipe 11. The condensate in the first branch pipe 12 is discharged through the first drain valve 121, and the remaining fluid material continues to flow in the material main pipe 1. The second pressure sensor 31 monitors the internal pressure of the material main pipe at the other end corresponding to the first filter 2 in real time, thereby determining the internal condition of the first filter 2 and preventing it from becoming clogged. Part of the fluid material flows into the discharge main pipe 11 through the second branch pipe 13. The condensate in the second branch pipe 13 is discharged through the second drain valve 131, and the remaining fluid material continues to flow in the material main pipe 1. The first pneumatic valve 4 controls the flow rate of the remaining fluid material. The control system includes a third pressure sensor 32 that monitors the internal pressure of the material main pipe 1 at the end corresponding to the second filter 21 in real time. After passing through the third pressure sensor 32, the remaining fluid material enters the second filter 21 for filtration. Part of the filtered fluid material flows from the second branch pipe 51 into the third branch pipe 14 and then into the discharge main pipe 11. The condensate in the third branch pipe 14 is discharged through the third drain valve 141. The remaining fluid material continues to flow within the material main pipe 1. A fourth pressure sensor 33 monitors the internal pressure of the material main pipe at the other end corresponding to the second filter 21 in real time, thereby determining the internal condition of the second filter 21 and preventing blockage. The remaining fluid material flows into the discharge main pipe 11 through the fourth branch pipe 15, and the condensate in the fourth branch pipe 15 is discharged through the fourth drain valve 151. Through the cooperation of the third pneumatic valve 42, the first temperature sensor 7, and the second temperature sensor 71, the temperature of the device can be maintained within the required range.
