[0030] A purification component 7 is provided in the air outlet 104; the purification component 7 comprises a fixing ring 701 fixed in the air outlet 104 and oil-blocking cotton 702 laid on the fixing ring 701;

[0031] The condensation assembly 3 includes a plurality of X-shaped brackets 301 that are equidistantly distributed, and the two ends of the X-shaped brackets 301 are respectively fixed on two opposite side walls in the flow chamber 102, and a connecting pipe 303 is fixed through two adjacent X-shaped brackets 301;

[0032] The purification box 1 is installed above the CNC machine tool. The interior of the purification box 1 is divided into an installation room 101 and a flow chamber 102 by a partition 103.

It can effectively increase the air flow rate and increase the instantaneous concentration of the inhaled oil mist. In addition, the oil mist has a large viscosity, so the wall hanging effect is obvious. In this way, a considerable part of the oil mist is directly left in the flow chamber 102 to achieve a primary filtering process.

With the circulating input and output cooling water, the X-shaped brackets 301 are always kept in a low temperature state. When the oil mist contacts the surface of the X-shaped bracket 301, oil droplets are quickly formed, thereby separating the oil molecules contained in the oil mist and realizing condensation-type filtration and purification treatment.

[0036] An external thread 1041 is provided on the outer wall of the air outlet 104, a thread groove 401 is provided at the lower part of the inner cavity of the hollow frame 4, and the hollow frame 4 is screwed and fixed to the external thread 1041 outside the air outlet 104 through the thread groove 401; the threaded connection structure makes it easier to replace the hollow frame 4 and the consumables installed thereon.
