DETAILED DESCRIPTION

[0027] The utility model will be further described below in combination with the drawings.

[0028] An oil filtering and residue filtering device, comprising a filter barrel 1, a filter basket 2, an oil pressing piston 3, and a drive cylinder 6, the filter barrel 1 is provided with an oil inlet 1-1 and an oil outlet 1-2, wherein the oil inlet 1-1 is used for inputting oil into the filter barrel 1, and the oil outlet 1-2 is used for outputting filtered oil outside the filter barrel 1; the filter basket 2 for filtering oil at the oil inlet 1-1 is installed at the oil inlet 1-1, and is used for filtering large-particle residues at the oil inlet 1-1; the filter cover 5 is arranged on the oil outlet 1-2, and is used for further filtering residues at the oil outlet, thereby improving the purity of the oil. The oil pressing piston 3 is slidingly installed in the filter barrel 1, the drive cylinder 6 is fixed on the top of the filter barrel 1 and connected with the oil pressing piston 3, and is used for driving the oil pressing piston 3 to move in the filter barrel 1, thereby improving the filtering efficiency of the oil by pressing the oil below the oil pressing piston 3.

[0029] In some embodiments, when the oil is pressed by the oil pressing piston 3, the oil inlet 1-1 needs to be controlled to stop oil inputting, and the oil level in the filter barrel 1 should be lower than the height of the oil inlet 1-1, then the oil pressing piston 3 is moved below the oil inlet 1-1, thereby pressing the oil and improving the filtering efficiency of the oil at the oil outlet 1-2.

[0030] In this embodiment, to improve the filtering continuity of the device, an opening groove 3-1 is formed on the oil pressing piston 3, and a baffle 4 is swingably installed in the opening groove 3-1. In the normal state, the baffle 4 is affected by gravity, so that the opening groove 3-1 is in an open state. When the oil pressing piston 3 moves downward to above the oil, the baffle 4 is affected by the buoyancy and the reaction force of the oil on the baffle 4, so that the baffle 4 abuts on the opening groove 3-1, so that the opening groove 3-1 is in a closed state, so as to press the oil by the oil pressing piston 3. During the pressing process, the oil in the oil inlet 1-1 can continuously enter the filter barrel 1. After the pressing is completed, the oil pressing piston 3 moves upward, and the baffle 4 swings downward under the action of its own weight and the gravity of the oil on the oil pressing piston 3, so that the opening groove 3-1 is in an open state, and the oil flows to the lower side of the oil pressing piston 3 through the opening groove 3-1. It should be noted that when the oil pressing piston 3 moves downward to above the oil, even if there is oil on the oil pressing piston 3, the sum of the oil gravity above the baffle 4 and the gravity of the baffle 4 is much smaller than the sum of the reaction force of the oil on the baffle 4 and the buoyancy of the baffle 4, that is, when the oil is pressed by the oil pressing piston 3, the baffle 4 must abut on the opening groove 3-1.

[0031] The opening groove 3-1 includes a through groove part 3-2 and a mounting groove part 3-3 connected at the bottom of the through groove part 3-2, and the baffle 4 is swingably installed in the mounting groove part 3-3. The opening and closing of the opening groove 3-1 are controlled by the swinging of the baffle 4. The area of the baffle 4 is greater than the area of the through groove part 3-2, so that when the baffle 4 abuts on the through groove part 3-2, the edge of the through groove part 3-2 is located inside the edge of the baffle 4, so as to realize the closing of the through groove part 3-2.

[0032] To ensure that the baffle 4 can stably abut on the through groove part 3-2, a stop rod 3-4 for limiting the baffle 4 is arranged at the bottom of the opening groove 3-1, so that the relative inclination angle between the baffle 4 and the bottom end face of the through groove part 3-2 is 4°-8°, so as to ensure that when the baffle 4 is affected by the buoyancy and the reaction force of the oil on the baffle 4, the baffle 4 swings towards the through groove part 3-2, and the through groove part 3-2 is closed.

[0033] A mounting ring 1-3 coaxially arranged with the oil outlet 1-2 is arranged at the bottom of the filter barrel 1, and the filter cover 5 is mounted on the oil outlet 1-2 through the mounting ring 1-3. The filter cover 5 includes a cylindrical filter screen 5-1 and a conical filter screen 5-2 connected above the cylindrical filter screen 5-1, so as to increase the filtering area and further improve the filtering efficiency.

[0034] To prevent interference between the oil pressing piston 3 and the filter cover 5 during the pressing process, an anti-interference hole 3-5 matched with the filter cover 5 is arranged on the oil pressing piston 3, and the filter cover 5 is inserted into the anti-interference hole 3-5 when the oil pressing piston 3 moves downward.

[0035] In order to facilitate the installation of the filter basket 2, the installation cavity 1-4 is formed on the side wall of the filter barrel 1, the installation cavity 1-4 extends to the outside of the side wall of the filter barrel 1, the filter basket 2 is detachably installed in the installation cavity 1-4, and the oil inlet 1-1 is arranged outside the installation cavity 1-4, so that the oil flows into the filter barrel 1 after passing through the filter basket 2.

[0036] In order to facilitate the fixing of the filter basket 2, the recess 1-5 is arranged on the inner wall of the filter barrel 1, the recess 1-5 is communicated with the installation cavity 1-4, and the filter basket 2 is fixedly connected with the recess 1-5 through screws.

[0037] The filter basket 2 comprises the receiving frame 2-1 and the filter plates 2-2 and the baffle plates 2-3 connected on both sides of the receiving frame 2-1, the baffle plates 2-3 and the receiving frame 2-1 form an opening, the oil enters the filter basket 2 through the opening, and then flows into the filter barrel 1 through the filter plates 2-2. When the filter basket 2 is removed, the filter residue is limited in the filter frame 2-1 through the baffle plates 2-3, so that the filter residue in the filter basket 2 is prevented from falling off.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application; therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
