Background
A large amount of dust is generated in the processing of cutting and polishing stone materials. Most of stone processing is equipped with a dust removing device to reduce environmental pollution and ensure production environment. As shown in fig. 4, the conventional stone dust removing mechanism is mostly implemented by filtering with two filtering layers consisting of a hard plastic filtering layer 1 and a paper filtering layer 2. After the dust air enters the air inlet of the dust removal device, the configured spraying mechanism 3 sprays water towards the hard plastic filter layer 1, most dust in the air is intercepted on the hard plastic filter layer 1, and the intercepted dust is flushed and reflowed into the water tank at the bottom through water flow.
As shown in fig. 4, during the operation of the dust removing device, the dust air travels along an L-shaped linear stroke (the direction of the dust air is shown by the arrow in fig. 4). When the hard plastic filter layer 1 and the paper filter layer 2 have good trafficability, the dust air passes through the two filter layers too fast, so that the dust scrubbing rate of the spraying mechanism 3 is low; and when two filtering layers are gradually blocked due to the deposition of dust, the workload of the exhaust port is increased, the dust removal rate of the dust is also sharply reduced, the dust removal effect is poor, the two filtering layers are frequently replaced, so that the use cost is high, the use is also troublesome, and the practicability of the product is poor.
