DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0020] Please refer to Figures 1 - 3 In the embodiments proposed in this application, there is a oil separator with a filtering function, including a tank body 1. On the left side of the top of the tank body 1, an input pipeline 2 is provided, and on the right side of the top, an output pipeline 3 is provided. At the bottom of the tank body 1, a liquid output pipe 4 is provided. The top of the input pipeline 2 is threadedly connected with a filtering connector 5. Inside the filtering connector 5, there is an impurity filter screen 51, which is used for the preliminary filtration of impurities when the mixed gas enters, filtering impurities from the source. And the threaded connection can be replaced at any time to ensure the filtering effect. Inside the tank body 1, a first cavity 11 is provided corresponding to the input pipeline 2, and a second cavity 12 is provided corresponding to the output pipeline 3. A first filtering structure 6 is provided in the first cavity 11, and a second filtering structure 7 is provided in the second cavity 12. The bottom of the first cavity 11 is communicated with the second cavity 12, and a second filter screen 8 is provided at the communication part of the first cavity 11 and the second cavity 12, which filters the mixed gas again when it passes through.
[0021] In another embodiment, please refer to Figures 1 - 3 In this embodiment, the first filtering structure 6 includes a plurality of first inclined plates 61 that are inclined and fixed in the first cavity 11, and the upper and lower adjacent first inclined plates 61 are cross-inclined. At the same time, a plurality of filter plates 62 are vertically provided on the first inclined plates 61, which greatly increases the contact area between the filter plates 62 and the mixed gas, accelerates the formation of large molecular droplets, enables them to be separated sufficiently, and the separation is more sufficient and rapid. First through holes 63 are respectively opened at the left and right ends of the first inclined plates 61, and first filter screens 64 are provided in the first through holes 63, so that the filtered mixed gas passes through the first filter screens 64 and enters the next link. And when entering, the mixed gas is filtered again through the first filter screens 64. Liquid guiding grooves 65 are provided at the left and right side walls of the first cavity 11 corresponding to the first through holes 63 of the first inclined plates 61. The filtered liquid is quickly introduced into the liquid output pipe 4 provided at the bottom of the tank body 1 through the liquid guiding grooves 65 and discharged.
[0022] In another embodiment, please refer to Figures 1 - 3 In this embodiment, the second filtering structure 7 includes a plurality of second inclined plates 71 that are inclined and fixed in the second cavity 12, and the adjacent second inclined plates 71 are cross-inclined. Second through holes 72 are opened on the downward side of the plurality of second inclined plates 71. Since the bottom of the first cavity 11 is communicated with the second cavity 12, when the mixed gas is filtered by the first filtering structure 6 and enters the second cavity 12 from the bottom and rises and is discharged from the output pipeline, during the rising process, the mixed gas collides with the second inclined plates 71. Since the second through holes 72 are located below the second inclined plates 71, the second inclined plates 71 can intercept the liquid in the mixed gas. Due to the inclined setting of the second inclined plates 71, the intercepted liquid will drip along the second inclined plates 71 to the lower liquid output pipe 4 and be discharged.
