Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific examples, which should not be construed as limiting the invention.

Example 1

As shown in fig. 1-3, the utility model provides an oil return pipeline filter, including pipe 1, pipe 1 upper end fixed connection apron 11, pipe 1 lower extreme fixed connection blind plate 12, blind plate 12 upside fixed connection vertical setting guide tube 2, guide tube 2 internal sliding connection standpipe 3, guide tube 2 inner wall is equipped with spiral spout 21, standpipe 3 outer wall fixed connection slider 31, slider 31 and spiral spout 21 correspond to the setting; the slide 31 is able to move inside the helical chute 21 when the vertical tube 3 moves vertically inside the guide tube 2, so that the vertical tube 3 can move vertically inside the guide tube 2 in a rotating manner. A spring 22 is arranged in the guide pipe 2, the spring 22 is arranged between the blind plate 12 and the vertical pipe 3, and when the spring 22 is in a free state, the vertical pipe 3 extends out of the upper end of the guide pipe 2. The upper end of the vertical pipe 3 is fixedly connected with a flat plate 4, the upper side of the flat plate 4 is fixedly connected with a filter pipe 41, the filter pipe 41 is provided with a plurality of uniformly arranged filter holes 42, and a baffle ring 20 is fixedly connected between the guide pipe 2 and the circular pipe 1; be equipped with the water conservancy diversion hole on the apron 11, in the downthehole fixed connection honeycomb duct 5 of water conservancy diversion, in honeycomb duct 5 lower extreme stretched into filter tube 41, pipe 1 was equipped with the oil gallery, and fixed connection returns oil pipe 6 in the oil gallery, 1 inner wall fixed connection filter 61 of pipe, filter 61 and the corresponding setting of oil pipe 6. The oil can flow into the filter pipe 41 along the flow guide pipe 5, and after the oil in the filter pipe 41 is filtered by the filter holes 42, the filtered oil can flow to the upper side of the baffle ring 20 in the circular pipe 1; as the oil in the filter tube 41 increases, the weight of the oil presses the plate 4 downward, and the plate 4 causes the vertical tube 3 to compress the spring 22 in the guide tube 2 and move vertically downward, so that the plate 4 with the filter tube 41 can move vertically downward in a rotating manner. As the oil in the filter tube 41 gradually flows out of the filter holes 42, when the weight of the oil in the filter tube 41 is smaller than the reaction force of the spring 22, the flat plate 4 can drive the filter tube 41 to move vertically upwards in a rotating manner under the action of the spring 22. In the rotating process of the filtering pipe 41, the contact between the oil liquid in the filtering pipe 41 and the filtering holes 42 is increased, so that the filtering effect of the filtering holes 42 on the oil liquid is improved. Fluid after the filtration can be through returning oil pipe 6 and flowing to, when fluid flowed in back oil pipe 6, fluid can take place the contact with filter 61 earlier, and filter 61 can filter fluid once more, with the improvement to the filtration quality of fluid.

The upper end of the filtering pipe 41 is fixedly connected with a plurality of projections 411, the projections 411 are uniformly arranged by taking the axis of the filtering pipe 41 as a reference, and the projections 411 are arranged corresponding to the cover plate 11. When the flat plate 4 drives the filtering pipe 41 to vertically move upwards, under the action of the spring 22, the bump 411 at the upper end of the filtering pipe 41 collides with the cover plate 11, so that the filtering pipe 41 vibrates, and thus when the filtering pipe 41 filters oil, oil residues attached to the filtering holes 42 are vibrated down, so that the service time of the filtering pipe 41 is prolonged.

Dull and stereotyped 4 upside is equipped with concave surface 7, 3 inner wall fixed connection passage pipes 8 of standpipe, blind plate 12 is equipped with the hole of stepping down 81, passage pipe 8 can pass and stretch out blind plate 12 downside through the hole of stepping down 81 from the spring 22 internal diameter, dull and stereotyped 4 is equipped with the guide hole, the guide hole is equipped with the lower at concave surface 7, the guide hole with step down the coaxial setting of hole 81, the guide hole internal diameter is the same with 8 internal diameters of passage pipe, 8 interpolation joints cooperation connection sprue bars 9 in the passage pipe, 9 upper end fixed connection end caps 91 of sprue bars, end caps 91 correspond the setting with the guide hole, end caps 91 can seal the guide hole. Residual oil and filtered oil residues in the filter pipe 41 can be concentrated at the bottom of the concave surface 7, the blocking rod 9 is pulled downwards, the blocking rod 9 and the plug 91 can be moved out of the material guide pipe 8, the residual oil and the oil residues collected in the concave surface 7 can flow out of the circular pipe 1 along the material guide pipe 8 through the material guide holes, and therefore the filter pipe 41 is cleaned, and the service time of the filter pipe 41 is further prolonged.

During the use, fluid flows into in the filter tube 41 along honeycomb duct 5, along with the change of the interior fluid of filter tube 41, can make filter tube 41 with the vertical reciprocating motion of pivoted mode, the fluid of filter tube 41 with cross the contact between the filtration pore 42 and increase to improve the filter effect of filtration pore 42 to fluid. And, when the filter pipe 41 moves up vertically, the bump 411 at the upper end of the filter pipe 41 collides with the cover plate 11, so that the filter pipe 41 vibrates, and when the filter pipe 41 filters oil, oil residues attached to the filter holes 42 are vibrated down, thereby prolonging the service life of the filter pipe 41.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
