Detailed Description

In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the present invention is not limited to the limitations of the specific embodiments of the present disclosure.

Embodiment 1, as shown in fig. 1, fig. 2, fig. 3, an impurity filtering device for lubricating oil production mainly is used for filtering the impurity in the lubricating oil, the utility model discloses a casing 1, casing 1 bottom are equipped with inlet tube 2, and lubricating oil can get into casing 1 from inlet tube 2, and casing 1 top is equipped with outlet pipe 3, and outlet pipe 3 is used for discharging the lubricating oil that has filtered, in order to realize the simple and easy quick assembly disassembly of coarse strainer 4 and fine filter screen 5, is equipped with solid fixed ring 6 in the casing 1, and solid fixed ring divide into the three-layer, for layer upon layer superimposed structure. The fixing ring 6 is annularly arranged in the middle of the shell 1, the fixing ring 6 comprises an upper screw hole ring 101 and a lower screw hole ring 102, the upper screw hole ring 101 and the lower screw hole ring 102 are respectively provided with an upper screw hole 103 and a lower screw hole 104 for fixing, the lower screw hole ring 102 is connected with the coarse strainer 4 through bolts, a fine strainer 5 for secondary filtration is arranged above the coarse strainer 4, and outlets of the two strainers are corresponding. Thin filter screen 5 and coarse filter screen 4 all are cyclic annular setting, thereby can increase the filter screen surface area increase efficiency, thin filter screen 5 is equipped with connecting rod 8, and connecting rod 8 sets up near thin filter screen 5 export, and connecting rod 8 end is equipped with ring 7, and ring 7 corresponds lower part screw 103, even can pass ring 7 with the bolt and screw up in lower part screw 103, makes ring 7 fixed. Specifically, when the filtering device is in operation, lubricating oil enters the shell 1 from the water inlet pipe 2, the lubricating oil in the shell 1 enters the annular coarse filter screen 4 through preliminary filtration, then the lubricating oil enters the annular fine filter screen 5 from the top outlet of the coarse filter screen 4, because the bottom of the annular fine filter screen 5 is sealed by the cover 10, the lubricating oil enters the space between the annular fine filter screen 5 and the shell 1 after being filtered by the annular fine filter screen 5, then the lubricating oil is discharged by the water outlet pipe 3, when the coarse filter screen 4 and the fine filter screen 5 need to be taken down for replacement, only the bolts in the screw holes 103 on the upper portion need to be loosened, the ring 7 for fixing action, the connecting rod 8 is separated from the screw holes 103, the fine filter screen 5 can be taken down, the bolts in the screw holes 104 on the lower portion are loosened, and the fine filter screen 5 can be separated from the fixing ring 6.

In order to make the lubricant oil enter the fine filter screen 5 from the coarse filter screen 4, the bottom and the top of the fine filter screen 5 are respectively provided with a cover 10 and a rubber ring 9, and the cover 12 can prevent the lubricant oil from leaking out of the bottom of the fine filter screen 5 without being filtered. When bolt fastening ring 7 and upper portion screw 103, make the solid fixed ring's of closely laminating surface in thin filter screen 5 top simultaneously, rubber circle 9 can improve sealed effect, makes lubricating oil can not flow from between thin filter screen 5 and the fixed ring surface. The top of coarse strainer 4 is provided with a plurality of coarse strainer screw holes 105 around the axis of coarse strainer, the coarse strainer screw holes 105 correspond to the lower screw holes 104, the coarse strainer 4 can be mounted on the lower screw hole ring 102 by tightening the bolts, and the edge of the coarse strainer 4 is closely attached to the surface of the lower screw hole ring 102, so that the lubricating oil filtered by the coarse strainer 4 does not enter the space between the coarse strainer 4 and the housing 1 again. Because of the existence of the fixing ring 6, the outlet from the coarse filter screen 4 to the outlet from the fine filter screen 5 is sealed, so that the leakage of the filtered lubricating oil or the entry of the unfiltered lubricating oil is prevented, and the lubricating oil can only enter the fine filter screen 5 from the coarse filter screen 4 and then enters the water outlet pipe 3 after being filtered.

In order to make the top of the fine screen 5 closely fit with the upper surface of the lower screw ring 102, the diameter of the upper screw ring 101 is larger than that of the lower screw ring 102, so that the mesh opening of the fine screen 5 can penetrate through the upper screw ring 101, and the diameter of the top of the fine screen 5 is larger than that of the lower screw ring 102, so that the mesh opening of the fine screen 5 can contact with the upper surface of the lower screw ring 102.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in other forms, and any person skilled in the art may use the above-mentioned technical contents to change or modify the equivalent embodiment into equivalent changes and apply to other fields, but any simple modification, equivalent change and modification made to the above embodiments according to the technical matters of the present invention will still fall within the protection scope of the technical solution of the present invention.
