[0028] Sealing rings are bonded to both sides of the filter plate 10, and one side of the sealing ring seamlessly slides and fits on one side of the support plate 13. The sealing ring prevents the size difference of the filter plate 10 from causing VOCs gas leakage, and cooperates with the rubber plate 513 to achieve double sealing to prevent VOCs gas leakage. The pressure sensor 14 is respectively located on one side of the support plate 13. A discharge port 6 located on one side of the filter plate 10 is opened on one side of the device box 1. An air inlet pipe 4 connected to the air inlet end of the filter box 15 is fixed on one side of the device box 1. An suction fan 9 is installed inside the air inlet pipe 4.

A maintenance door 2 installed on one side of the storage box 11 is provided on one side of the device box 1. The maintenance door 2 is opened to put the filter plate 10 into the storage box 11.

[0029] In order to facilitate the replacement of the filter plate 10, a replacement component 5 is provided. The replacement component 5 includes a first electric push rod 51 and a support plate 54. A second electric push rod 55 and a support frame 56 are fixed on the top of the support plate 54 respectively. A baffle 53 is fixed to the push rod end of the first electric push rod 51. A rubber plate 513 is bonded to one side of the baffle 53. A slide rail 52 located on both sides of the discharge port 6 is installed on one side of the device box 1. Both sides of the baffle 53 are slidably connected to the inner side of the track groove of the slide rail 52. One side of the rubber plate 513 is seamlessly slidably connected to one side of the discharge port 6. When the filter plate 10 does not need to be replaced, the rubber plate 513 is blocked on one side of the discharge port 6 to avoid VOCs gas leakage due to size differences of the filter plate 10.

[0030] In order to facilitate the replacement of the filter plate 10, a push plate 511 is fixed to the push rod end of the second electric push rod 55, and the push plate 511 is movably inserted into one side of the storage box 11. A slide groove 58 is opened inside the support frame 56, and a slide plate 59 is slidably connected to the inner side of the slide groove 58. A connecting plate 57 that movably penetrates the inner wall of the slide groove 58 is fixed to one side of the slide plate 59. A switch 512 located on one side of the slide plate 59 is installed on the inner wall of the slide groove 58. A spring 510 is connected between the slide plate 59 and the slide groove 58. The push plate 511 leaves one side of the connecting plate 57. At this time, under the elastic force of the spring 510, the slide plate 59 is pushed to slide inside the slide groove 58, and the slide plate 59 triggers the switch 512. The switch 512 controls the push rod end of the first electric push rod 51 to retract, and the connecting plate 57 is located at the push plate 51 1, the controller 12 controls the push rod end of the second electric push rod 55 to extend, and the push rod end pushes the push plate 511 to move toward the side of the filter plate 10 inside the storage box 11, and the controller 12 is installed on one side of the support frame 56. The output ends of the pressure sensor 14 and the switch 512 are electrically connected to the input end of the controller 12, and the output ends of the controller 12 are electrically connected to the input ends of the first electric push rod 51 and the second electric push rod 55 respectively. One side of the first electric push rod 51 is fixed to one side of the device box 1, and one side of the support plate 54 is fixed to one side of the filter box 15. The new filter plate 10 is pushed between the two support plates 13, and at the same time, the new filter plate 10 pushes the old filter plate 10 out of the discharge port 6, and at the same time, the sealing strips on both sides of the filter plate 10 are attached to one side of the support plate 13.

[0031] The model of the pressure sensor 14 is: MPX2010;

[0032] The model of the controller 12 is: FX1S.

[0033] Working principle or structural principle: When VOCs gas needs to be treated, it is only necessary to connect the air inlet pipe 4 with the VOCs gas outlet, and then start the suction fan 9 and the blower 7 respectively to suck the VOCs gas into the inner side of the filter box 15. At this time, the VOCs gas passes through the filter plate 10 to adsorb the VOCs gas. At the same time, a spray box, an ultraviolet lamp sterilization box and an activated carbon filter box are respectively arranged on one side of the filter box 15. Finally, the filtered gas is discharged through the air outlet pipe 8 under the power of the blower 7.

[0034] When filtering the VOCs gas, the push rod end of the first electric push rod 51 extends out, so that the rubber plate 513 blocks one side of the discharge port 6, to avoid the filter plate 10 having a small size difference, which causes the VOCs gas to leak from the discharge port 6. When the two pressure sensors 14 detect that the pressure difference on both sides of the filter plate 10 inside the filter box 15 is large, it means that the filter plate 10 has adsorbed a large amount of VOCs gas. The controller 12 controls the push rod end of the second electric push rod 55 to extend, and the push rod end pushes the push plate 511 to move to the side of the filter plate 10 inside the storage box 11, and pushes the new filter plate 10 between the two support plates 13. At the same time, the new filter plate 10 pushes the old filter plate 10 out of the discharge port 6, and the sealing strips on both sides of the filter plate 10 are attached to one side of the support plate 13.

[0035] At this time, the push plate 511 leaves one side of the connecting plate 57. Under the elastic force of the spring 510, the slide plate 59 is pushed to slide inside the slide groove 58. At the same time, the slide plate 59 triggers the switch 512. The switch 512 controls the push rod end of the first electric push rod 51 to retract, so that the baffle plate 53 slides inside the track groove of the slide rail 52, and at the same time drives the rubber plate 513 to leave the side of the discharge port 6. At this time, the replacement of the filter plate 10 is completed, and the rubber plate 513 blocks the side of the discharge port 6 to prevent the VOCs gas from leaking through the discharge port 6 during processing.

[0036] In summary, when the push rod end of the first electric push rod 51 is extended and the rubber plate 513 is blocked on one side of the discharge port 6, the VOCs gas leakage from the discharge port 6 due to the possible slight difference in the size of the filter plate 10 is effectively avoided. The push rod end of the second electric push rod 55 is extended, and the push rod end pushes the push plate 511 to move, thereby realizing the automatic replacement of the filter plate 10, which not only improves the operating efficiency and reduces the trouble of manual replacement, but also reduces the risk of contact between operators and harmful VOCs gases; when the two pressure sensors 14 detect that the pressure difference on both sides of the filter plate 10 inside the filter box 15 is large, it means that the filter plate 10 has adsorbed a large amount of VOCs gas. Replacement at this time can make full use of the adsorption capacity of the filter plate 10 to ensure the continuous and efficient operation of the filtration system.
