Detailed Description

The utility model provides an integral type oil mist filter. The technical solution of the present invention will be described in detail below with reference to the accompanying drawings so as to be easier to understand and grasp.

An integrated oil mist filter, as shown in fig. 1 and 2, includes a filter housing 1, and an inlet pipe end 2 and an outlet pipe end 3 are respectively provided on a set of opposite side walls of the filter housing 1.

The filter comprises a first filter, a second filter, a third filter and a terminal filter which are sequentially arranged in the filter shell 1 along the direction from the air inlet pipe end 2 to the air outlet pipe end 3.

The first filter is a filter cotton cylinder 4 covered on the air inlet pipe end 2, the second filter is a filter screen plate 5, the third filter is a filter screen cylinder 6 arranged vertically, and the terminal filter is a terminal filter screen cylinder 8 with an inner pipeline 7 communicated with the air outlet pipe end 3.

A partition plate 9 arranged between the filter screen plate 5 and the filter screen cylinder 6 is arranged in the filter shell 1, and a communication pipeline 11 extending to an inner cavity 10 of the filter screen cylinder 6 is arranged on the partition plate 9.
