a separator ash falling port 71 is arranged at the rear end of the horizontal centrifugal separator 7, a first ash collecting box 81 is arranged at the separator ash falling port 71, a separator air outlet 72 is arranged at the front end of the horizontal centrifugal separator 7, a filter cylinder 9 is arranged at the separator air outlet 72, a negative pressure fan 10 is arranged at the air outlet of the filter cylinder 9, and a third ash collecting box 83 is arranged at the bottom of the filter cylinder 9; the dust filtered by the filter cartridge 9 is scraped off and falls into the third dust collecting box 83, so that the filtering can be cleaned. The filtration is cartridge filtration, which has the advantage of providing a larger filtration area in a smaller space.
Referring to fig. 2, the air rotation travel axis of the horizontal centrifugal separator 7 is parallel to the cutting table 2. When the dust-containing air enters the separator shell, the air advances spirally along the inner wall of the shell, the dust-containing air forms spiral airflow and advances in a fixed direction, when the dust-containing air advances spirally at a high speed, most dust particles in the airflow reach the inner wall of the shell under the action of centrifugal force, the dust particles are separated from the air, the separated dust particles enter the dust falling port 71 of the separator and fall into the first dust collecting box 81 along the tangential direction after reaching the rear end of the separator to complete dust-air separation, and the separated air leaves the separator from the air outlet 72 of the separator after turning back at the rear end. The centrifugal separator adopts a horizontal structure, so that the height of the equipment can be reduced, the volume of the equipment is reduced, and the centrifugal separator is convenient to carry.
During installation, the lower part of the embedded block 22 and the main workbench 21 are sealed, and the lower part of the main workbench 21 and the upper part of the air suction bin 6 are sealed. The air generated by the negative pressure fan 10 can only enter from the saw mouth 3 and the air inlet of the air suction bin, and the operations such as saw blade replacement and the like can be conveniently carried out after the embedded block 22 is removed. During operation, the wind speed at the wind inlet of the air suction bin is preferably greater than the linear speed of rotation of the saw blade 4, so that the high-speed airflow can effectively suck dust generated by cutting into the air suction bin 6.
Referring to fig. 3, an exhaust bin 11 is arranged in the casing 1, the saw blade driving motor 5 and the negative pressure fan 10 are both installed in the exhaust bin 11, and an air outlet 12 is arranged at the tail end (C-D) of the exhaust bin 11.

The first dust collecting box 81 is used for collecting dust generated by the horizontal centrifugal separator, the second dust collecting box 82 is used for collecting larger particles in the suction bin, and the third dust collecting box 83 is used for collecting dust at the filter cartridge.
Referring to fig. 1 to 3, the working principle of the present invention is as follows: when the saw blade 4 rotates at a high speed to cut the workpiece 14, the wind speed at the saw cut 3 (the wind inlet of the wind suction bin) is ensured to be larger than the rotating linear speed of the saw blade 4, so that the high-speed airflow at the wind inlet of the wind suction bin can effectively carry all dust/chips generated by cutting into the wind suction bin 6, dust-containing gas is separated from air through the horizontal centrifugal separator 7 and the filter drum 9, and clean air is discharged into the atmosphere through the negative pressure fan 10. Thus, most of the dust is separated in advance in the horizontal centrifugal separator 7, only a small amount of fine dust needs to be filtered, so that the filter material can adopt high-efficiency filtration, and the dust discharge requirement can be less than 50 mu g/m3The device realizes clean discharge, ensures that the filter is not easy to block, greatly prolongs the period of cleaning or replacement, and can ensure the long-term stable operation of the device.
