detailed description

Below in conjunction with accompanying drawing, the utility model will be further described:

Referring to Fig. 1, a kind of double-layer oil-filtered air filter used between the Czochralski furnace and the vacuum pump comprises the filter tank upper cover 1-1, the filter tank tank bottom 1-2 and the filter tank tank body 1-3 assembly The filter tank 1 formed together also includes a metal filter screen 2, a layered baffle plate 3, an air inlet I4, an air inlet II5, a primary sewage discharge port 6, a secondary sewage discharge port 7, an air outlet 8, an observation port 9, Cone reflector 10, filter oil 11.

The conical reflector (10) is umbrella-shaped.

The layered baffle 3 is arranged in the filter tank body 1-3 to divide the filter tank body 1-3 into upper and lower oil filter areas, the upper oil filter area is for fine filtration, and the lower oil filter area is for coarse filtration. The air inlet II5 is arranged on the baffle plate 3, and the conical reflector 10 is fixed by several connecting columns on the air inlet II5, and the metal plate fixed with the filter tank body 1-3 is arranged in the oil filter area of the lower layer. The filter screen 2 is provided with an air inlet I4 on the wall of the filter tank body 1-3 in the lower oil filter area, and the outlet of the vertical end of the air inlet I4 entering the lower oil filter area passes through the metal filter screen 2 and is arranged on the lower oil filter screen. In the filter area, a secondary sewage discharge port 7 is provided at the lower end of the filter tank body 1-3 wall of the upper oil filter area, and a primary sewage discharge port 6 is provided on the bottom 1-2 of the filter tank. 1 is respectively provided with an air outlet 8 and an observation port 9, and an oil filter 11 is respectively installed in the upper oil filter area and the lower oil filter area.
