[0026] The pressing assembly 6 includes a mounting frame 601 , which is fixedly disposed at the middle end of a side wall of the dust removal box 3 close to the fan 4 .

[0027] Among them, the pressing component 6 further includes a bidirectional screw 602, an adjusting knob 603 and a movable block 604. The bidirectional screw 602 is rotatably arranged inside the mounting frame 601. The upper end of the bidirectional screw 602 passes through the upper wall of the mounting frame 601 and is connected to the adjusting knob 603. The thread directions of both ends of the bidirectional screw 602 are opposite. There are two movable blocks 604. The two movable blocks 604 are threadedly connected to the bidirectional screw 602. The movable blocks 604 are slidably connected to the inner wall of the mounting frame 601. By rotating the adjusting knob 603, the bidirectional screw 602 can be effectively driven to rotate synchronously. Under the limiting effect of the mounting frame 601, the two movable blocks 604 move along the bidirectional screw 602 to approach or move away from each other.

[0028] Among them, a driving rod 605 is arranged on the front surface of the movable block 604. A strip-shaped plate 606 is arranged at one end of the driving rod 605 away from the movable block 604. A pressing screw 607 is threadedly connected to one end of the strip-shaped plate 606 away from the driving rod 605. A pressing block 608 is arranged at one end of the pressing screw 607 close to the dust removal box 3. A pressing knob is arranged at one end of the pressing screw 607 away from the pressing block 608. A limiting sealing plate 501 is arranged on the front surface of the filter frame 5. Handles 502 are arranged at both ends of the front surface of the limiting sealing plate 501. When the filter frame 5 is inserted into the dust removal box 3, the two movable blocks 604 are driven to move away from each other, and the driving rod 605 and the strip-shaped plate 606 move synchronously and move away from each other. When the pressing screw 607 moves to the front of the limiting sealing plate 501, rotate the pressing knob to drive the pressing screw 607 to rotate and move towards the side close to the limiting sealing plate 501. Then, the pressing screw 607 pushes the pressing block 608 to press the limiting sealing plate 501. The installation and fixation of the filter frame 5 are convenient. When the filter frame 5 needs to be disassembled and replaced, first rotate the pressing knob to make the pressing block 608 disengage from the limiting sealing plate 501, and then rotate the adjusting knob 603 to drive the bidirectional screw 602 to rotate, so that the two movable blocks 604 approach each other and drive the two strip-shaped plates 606 to approach each other and move between the two limiting sealing plates 501. Then, the filter frame 5 can be pulled out by pulling the handle 502. The operation is simple, and the replacement of the filter frame 5 is convenient, ensuring the dust removal effect.

[0029] Among them; a sampling port 701 is provided at the middle end of the temporary storage box 7 away from the exhaust pipe 304, a discharge port 702 is provided at the upper end of the temporary storage box 7, and a return pipe 8 is provided at the lower end of the temporary storage box 7. The exhaust port at the lower end of the return pipe 8 is connected to the inside of the dust removal box 3, and valves are provided on the sampling port 701, the discharge port 702 and the return pipe 8. Initially, the dust-carrying airflow passes through the exhaust pipe 304 and enters the temporary storage box 7. At this time, the discharge port 702 is closed, and the valve on the return pipe 8 is opened. The filtered gas sample is taken out through the sampling port 701, and a test is carried out to determine whether it meets the standard, so as to avoid the situation where the exhaust airflow is unqualified due to damage to the filter frame 5. When the test is qualified, the discharge port 702 can be opened, and the filtered airflow is discharged to the outside through the discharge port 702, thereby effectively ensuring the dust removal effect.

[0030] Among them; a dust outlet 301 is provided at the lower end of the dust removal box 3, and support legs 2 are provided at the four corners of the lower end surface of the support platform 1. The dust outlet 301 is provided to facilitate the collection of talcum powder that falls to the bottom of the dust removal box 3. The support legs 2 can effectively support the support platform 1 to ensure the overall stability.

[0031] Working principle: when the filter frame 5 is inserted into the dust removal box 3, the bidirectional screw 602 is driven to rotate synchronously by turning the adjusting knob 603. Under the limiting action of the installation frame 601, the two movable blocks 604 can move along the bidirectional screw 602 and move away from each other, and the driving rod 605 and the strip plate 606 move synchronously and move away from each other. When the clamping screw 607 moves to the front of the limiting sealing plate 501, the clamping knob is turned to drive the clamping screw 607 to rotate and move toward the side close to the limiting sealing plate 501, and then the clamping screw 607 pushes the clamping block 608 clamps the limiting sealing plate 501, and the filter frame 5 is easy to install and fix. When the filter frame 5 needs to be disassembled and replaced, first turn the clamping knob to make the clamping block 608 separate from the limiting sealing plate 501, and then turn the adjusting knob 603 to drive the bidirectional screw 602 to rotate, so that the two movable blocks 604 approach each other and drive the two strip plates 606 to move closer to each other through the driving rod 605 to move between the two limiting sealing plates 501, and then the filter frame 5 can be pulled out by pulling the handle 502. The operation is simple, the filter frame 5 is easy to replace, and the dust removal effect is guaranteed.

[0032] Furthermore, initially, the dust-laden airflow is filtered by the filter frame 5 and then enters the temporary storage box 7 through the exhaust pipe 304. At this time, the discharge port 702 is closed, the valve on the return pipe 8 is opened, and the filtered gas sample is taken out through the sampling port 701 for detection to determine whether it meets the standards, so as to avoid the situation where the exhaust airflow is unqualified due to damage to the filter frame 5. When the test is qualified, the discharge port 702 can be opened, and the filtered airflow is discharged to the outside through the discharge port 702, thereby effectively ensuring the dust removal effect.
