The limiting device comprises a threaded rod 3, a fixed circular block 4, a limiting rod 5 and a limiting arc plate 6. The threaded rod 3 rotates to control the horizontal movement of the limiting arc plate 6. The limiting rod 5 is clamped into the fixed circular block 4 to limit the rotation of the threaded rod 3.

[0024] In order to facilitate the limiting of the outlet pipe 11, the upper end of the collecting box 1 is slidably inserted with the outlet pipe 11, the outer surface of the outlet pipe 11 is slidably connected to the inside of the mounting circular plate 2, the outer surface of the outlet pipe 11 is provided with an annular groove 12, and the inside of the mounting circular plate 2 is provided with a slide groove 21. The two limiting arc plates 6 are both slidably inserted in the inside of the slide groove 21, and the exhaust gas in the collecting box 1 is discharged through the outlet pipe 11. The annular groove 12 is convenient for limiting the position of the outlet pipe 11, and the limiting arc plate 6 is stuck in the annular groove 12 to limit the position of the outlet pipe 11.

[0025] In order to ensure that the limiting arc plate 6 can maintain a straight line for horizontal movement, the two limiting arc plates 6 are horizontally symmetrically distributed with the axis of the mounting circular plate 2 as the symmetry center. A limiting block 61 is fixedly installed on the upper surface of the limiting arc plate 6. The limiting block 61 is slidably inserted into the inside of the slide groove 21. The outer surface of the limiting arc plate 6 is slidably connected to the inside of the annular groove 12. The limiting block 61 is stuck in the slide groove 21 and slides, ensuring that the limiting arc plate 6 can maintain a straight line for horizontal movement.

[0026] In order to facilitate limiting the rotation of the threaded rod 3, the two threaded rods 3 are respectively rotatably connected to the two sides of the inside of the mounting circular plate 2, the front end of the threaded rod 3 is connected to the internal thread of the limiting arc plate 6, the fixed round block 4 is fixedly installed on the outer surface of the threaded rod 3, the limiting rod 5 is threadedly connected to the inside of the fixed round block 4, and the front end of the limiting rod 5 is connected to the internal thread of the mounting circular plate 2. Rotating the threaded rod 3 will drive the limiting arc plate 6 to move, and the limiting rod 5 is stuck in the fixed round block 4 to limit the rotation of the fixed round block 4, thereby limiting the rotation of the threaded rod 3.

[0027] In order to facilitate the control of the piston block 15 to suck and squeeze the exhaust gas, the upper end of the collecting box 1 is located on the right side of the air outlet cylinder 11 and is fixedly connected to the piston cylinder 13. The upper end of the piston cylinder 13 is slidably inserted with a piston rod 14. The lower end of the piston rod 14 is fixedly installed with a piston block 15. The outer surface of the piston block 15 is slidably connected to the inside of the piston cylinder 13. A filter element 16 is fixedly installed inside the air outlet cylinder 11.

When replacing the filter element 16, the limit rod 5 is first turned out from the outside of the fixed round block 4, and then the threaded rod 3 is rotated to control the limit arc plate 6 to move out of the annular groove 12, and then the air outlet tube 11 is pulled out of the collection box 1, and the filter element 16 is replaced and cleaned. The installation cover 18 can close the connecting pipe 17 during the exhaust gas discharge process to prevent exhaust gas leakage, thereby achieving the effect of facilitating the cleaning of the filter mechanism and preventing exhaust gas leakage.

[0030] Working principle: When collecting mercury waste liquid, the waste liquid is discharged into the collection box 1 through the connecting pipe 17, and then the piston rod 14 is moved in the piston cylinder 13, so that the piston block 15 sucks and squeezes the exhaust gas, and then the exhaust gas enters the air outlet tube 11, and is discharged after being filtered by the filter element 16.
