The working principle of the dust-absorbing dust-removing gas-making device 5 is as follows: the dust-containing gas enters the filter box body 51 from the inlet of the dust remover under the action of the negative pressure air flow, the dust is separated from the air flow through the filtering action of the filter cylinder 52, and the purified clean gas enters the air purifying chamber from the inside of the filter cylinder and is discharged; as the dust is filtered through the filter cartridge 52, the dust remains on the outer surface of the filter cartridge 52. When the ash is cleaned, the switch button is pressed to start the pulse valve, so that the compressed air in the air bag is sprayed to the corresponding venturis through the holes of the spraying pipe. Ambient air, which is several times the primary air, is induced into the filter cartridge 52 as the high velocity air stream passes through the venturi, causing the cartridge to expand instantaneously and sharply. The dust accumulated on the filter cartridge 52 falls off due to the reverse action of the air flow, and after the hand-releasing pulse valve is closed, the reverse air flow is generated again, so that the filter cartridge 52 retracts rapidly to form expansion and contraction, the expansion and contraction shaking of the filter cartridge 52 is formed, the powder cake accumulated on the outer part of the filter cartridge 52 falls off due to the inertia effect, the filter cartridge 52 is renewed, and the cleaned dust falls into the dust collection cover 53 at the lower part of the dust collector. The dust collecting cover 53 adopts a detachable design, and the dust is convenient to clean.

The equipment can adopt a PLC control technology and an automatic and manual mode of liquid crystal screen operation, and can be matched with a full Chinese operating button to easily finish sample preparation work.
