[0027] Working principle: Pour the laboratory waste liquid into the liquid inlet funnel 3. At this time, under the action of the gravity of the waste liquid, the one-way spring valve 4 is opened, so that the waste liquid is sent into the collection box 1 through the liquid seal pipe 2 for storage. And under the action of the U-shaped structure of the liquid inlet funnel 3 itself, a liquid seal can be formed inside the liquid inlet funnel 3, thereby improving the sealing performance of the collection box 1. When the waste liquid inside the collection box 1 continuously occupies the internal space of the collection box 1, at this time, the excess air inside the collection box 1 and the gas volatilized from the waste liquid will move upward through the exhaust pipe 5. When the air pressure inside the collection box 1 is greater than the set threshold value of the spring exhaust valve 6, the spring exhaust valve 6 automatically opens, and then the excess air and volatilized gas will be sent into the treatment box 7, and the harmful substances in the gas will be filtered by the activated carbon filter screen 10, and finally discharged through the ventilation pipe 8 to avoid environmental pollution. When the activated carbon filter screen 10 needs to be replaced, just press the handle blocks 25 on both sides of the fixing device 17, drive the connecting rod 24 to drive the triangular block 23 to slide along the inclined plane on the inclined plane block 22, so that the L-shaped buckles 20 at both ends can slide along the sliding rod 19, and the second spring 21 is compressed, so as to release the limiting effect on the limiting plate 11. At this time, under the action of the first spring 16 in the compressed state, the activated carbon filter screen 10 can be pushed out along the sliding groove 9 through the extrusion column 13, so as to realize the disassembly of the activated carbon filter screen 10. Then insert the new activated carbon filter screen 10 into the sliding groove 9. When the activated carbon filter screen 10 contacts the extrusion column 13, continue to push the activated carbon filter screen 10, so that the extrusion column 13 squeezes the first spring 16 through the limiting ring 14. At this time, the L-shaped buckle 20 passes through the through hole 26, release the handle block 25, and under the restoring force of the second spring 21, the L-shaped buckles 20 at both ends automatically open to realize the limiting and fixing of the limiting plate 11, that is, the installation of the activated carbon filter screen 10 is completed, which is simple and convenient.
