The specific embodiment
Embodiment
Refer to Fig. 1 ~ 4, the present invention has disclosed a kind of oily water separating equipment structure, comprising:
One housing, comprise main cylinder 6, upper cover 13, low head 3 and secondary cylindrical shell 2, main cylinder 6 upper and lower ends connect respectively upper cover 13 and low head 3, wherein, upper cover 13 lower ends arrange upper cover adpting flange 12, main cylinder 6 upper ends arrange cylindrical shell adpting flange 11, and main cylinder 6 is connected and fixed by upper cover adpting flange 12, cylindrical shell adpting flange 11 with upper cover 13.
