Referring to fig. 1-3, a drainage and pollution discharge structure of a diesel oil filter, comprising a casing 1, wherein the casing 1 is a casing part of the filter, a pollution discharge hole 2 is formed at the bottom of the casing 1, a plurality of connecting rods 3 are welded on the inner wall of the pollution discharge hole 2, a sliding sleeve 4 is welded and fixed together with the plurality of connecting rods 3, a relatively obvious gap is formed therein, so that moisture and impurities in the casing 1 can rapidly flow out, a sliding column 5 is sleeved in the sliding sleeve 4 in a sliding manner, a floating block 6 is fixed at one end of the sliding column 5, which is positioned in the casing 1, a baffle 13 is fixed at one end of the sliding column 5, which is positioned outside the casing 1, a second spring 12 is welded and fixed at one side of the baffle 13, which is close to the casing 1, one end of the second spring 12, which is far away from the baffle 13, is welded and fixed with the outer wall of the casing 1, a circular, the sealing rubber strip 11 covers the sewage draining hole 2 inside, so that when the sealing rubber strip 11 is abutted against the lower wall of the shell 1, water in the shell 1 cannot flow out of the sewage draining hole 2.

Two rotating plates 8 are symmetrically arranged in the middle of the sliding column 5, the rotating plates 8 are rotatably connected to the sliding column 5 through pin shafts, one side, close to a baffle 13, of each rotating plate 8 is fixedly glued with a first spring 9, one side, far away from the corresponding rotating plate 8, of each first spring 9 is fixedly welded to the sliding column 5, two stop rods 7 are symmetrically welded to the position, located between the rotating plate 8 and the floating block 6, of the sliding column 5, and the two stop rods 7 are obliquely arranged and used for limiting the maximum rotating position of the rotating plates 8;

the sewage discharge hole 2 is a circular through hole, the sewage discharge hole 2 and the sliding column 5 are concentrically arranged, the inner diameter of the sealing rubber strip 11 is larger than the diameter of the sewage discharge hole 2, and the sealing rubber strip 11 is ensured to cover the sewage discharge hole 2 inside, so that when the sealing rubber strip 11 abuts against the lower wall of the shell 1, water in the shell 1 cannot flow out of the sewage discharge hole 2; a pull ring 14 is welded and fixed on one side of the baffle 13, which is far away from the sliding column 5, so that a user can pull or push the baffle 13 conveniently; the floating block 6 is made of foam materials, so that the floating block 6 has larger buoyancy; one end of the stop lever 7, which is far away from the sliding column 5, is as high as the connecting part of the rotating plate 8 and the sliding column 5, so that one of the limit positions of the rotating plate 8 in the rotating process is in a horizontal state;

in the utility model, casing 1 is the shell of filter, and the oil inlet and the oil-out of filter are located the upper end of filter, and filter work can make clear water sink in casing 1's bottom, because the impurity in the diesel oil mainly is the material that density such as silica, iron oxide, aluminium oxide is greater than water, so after the impurity filtering of filter core in with the diesel oil, most impurity also can deposit in casing 1's bottom.

When the filter is not used, the interior of the shell 1 is completely filled with diesel oil, the density of the diesel oil is small, the buoyancy generated by the diesel oil to the floating block 6 is small and is far smaller than the elastic force of the second spring 12, at the moment, the second spring 12 acts to enable the sealing rubber strip 11 on the circular plate 10 to be tightly abutted against the bottom of the shell 1, and the sealing rubber strip 11 concentrically surrounds the sewage discharge hole 2, so that the diesel oil in the shell 1 cannot flow out of the sewage discharge port 2, and the filter can be ensured to normally work;

when water in the filter accumulates to submerge the floating block 6, because the density of the water is greater than that of the diesel oil, namely the floating block 6 is submerged in the water and bears larger buoyancy force, at the moment, the floating block 6 can drive the sliding column 5 to move upwards by a small amount to compress the second spring 12, so that a certain gap is generated between the sealing rubber strip 11 and the bottom of the shell 1, the water at the lower end of the shell 1 flows out from the gap, the liquid level of the water in the shell 1 is reduced after the water flows out, the volume of the submerged floating block is reduced, the volume of the diesel oil submerged floating block 6 is increased, the buoyancy force borne by the floating block 6 is reduced, at the moment, the sliding column 5 and the floating block 6 move downwards under the action of the second spring 12 until the sealing rubber strip 11 is tightly abutted against the inner wall of the shell 1 again, so that the water in the shell 1 cannot continue to flow out, thereby ensuring that the water in the shell 1 is kept at a certain amount, the situation that water enters the engine due to excessive water accumulation in the filter is avoided.

After the filter works for a long period of time, the water in the shell 1 is positioned at the floating block 6, more impurities are accumulated at the bottom of the shell 1, at the moment, the baffle 13 is pushed upwards violently to drive the sliding column 5, the floating block 6 and the rotating plates 8 to move upwards, and in the process, the rotating plates 8 rotate under the resistance action of the water, so that one side of each rotating plate 8, which is far away from the sliding column 5, is close to the middle; after the hands are loosened, the second spring 12 drives the baffle 13 and the sliding column 5 to move downwards, the rotating plate 8 rotates under the combined action of the elastic force of the first spring 9 and the resistance of water until the rotating plate 8 is propped against the stop lever 7 to be in a horizontal state, then the rotating plate 8 moves downwards along with the action of the sliding column 5 until the sealing rubber strip 11 is pressed against the bottom of the shell 1 again, in the process, the rotating plate 8 and the circular plate 10 push the surrounding water downwards, so that the water at the bottom of the shell 1 is discharged from the sewage discharge hole 2, and as the rotating plate 8 is parallel to the moving direction of the sliding column 5 in the downward movement process, so the water downstream around 8 at utmost of driving of rotor plate is discharged from blowoff hole 2 to can drive the impurity of casing 1 bottom and discharge along with rivers, realize discharging the impurity of casing 1 inside, avoid the too much filter effect who influences the filter core of the inside impurity of casing 1.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
