After adopting said structure, as can be seen, equipment of the present utility model not only can carry out the physical sepn of oil, mud and water preferably, non-secondary pollution, but also have simple in structurely, operation and maintenance is easy, facility investment is little and running cost is low, and the production efficiency advantage of higher.

Description of drawings

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

Fig. 1 is a kind of structural representation of the utility model water-and-oil separator.

Embodiment

Referring to a kind of water-and-oil separator shown in Figure 1, comprise a cylindrical shell 1 that is used to deposit profit, the bottom of described housing 1 is doline and in the inside of this housing 1 heating tube 2 is set, and this water-and-oil separator also comprises a transparent tube 3, Y-tube 4, mud collection box 5, dirty water collecting tank 6 and a grease collection box 7; Fixedlying connected with the small-caliber end of described housing 1 funnel-shaped bottom portion in the upper end of described transparent tube 3, fixedlys connected with the upper end of described Y-tube 4 in the lower end; One side bypass pipe of described Y-tube 4 links to each other with described mud collection box 5 by pipeline 8, and the opposite side bypass pipe links to each other with described grease collection box 7 by pipeline 8; The upper end of described mud collection box 5 links to each other with described dirty water collecting tank 6 by pipeline 8; On the pipeline 8 of two side bypass pipes of described Y-tube 4, also be respectively equipped with a valve 9.Described transparent tube 3 of the present utility model can adopt Glass tubing.
