Specific embodiments

[0024] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. 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 scope of protection of the present utility model.

[0025] Embodiment 1:

[0026] Referring to Figure 1-9 , the P-C dual-polarity adsorption oil purification device includes a housing 1. An oil inlet 101 is provided at the top of the housing 1, an oil outlet 102 is provided at the bottom of the housing 1, and a filter screen 103 is provided inside the housing 1. When the staff pours oil into the housing 1 through the oil inlet 101, the provided filter screen 103 will filter the particulate matter or impurities in the oil. Mounting frames 104 are provided around the filter screen 103. An opening 105 is provided on one side of the housing 1. The mounting frame 104 is slidably connected to the opening 105. A card slot 106 is provided on the side of the mounting frame 104 close to the opening 105. An accommodating block 110 is provided inside the housing 1 close to the card slot 106. A card block 107 is provided inside the accommodating block 110. A fixing mechanism for engaging or disengaging the card block 107 with the card slot 106 is provided inside the accommodating block 110. The cross-sections of the card block 107 and the card slot 106 can be designed as a square structure. The design of the square structure can provide a larger contact area and a tighter connection, making the card block 107 more stable in the card slot 106.

[0027] Through the provided opening 105, mounting frame 104, and fixing mechanism, when the staff needs to clean the surface of the filter screen 103, first use the fixing mechanism to disengage the clamping block 107 from the clamping groove 106 on the mounting frame 104, and then directly extract the mounting frame 104 through the opening 105. The mounting frame 104 will drive the filter screen 103 to disengage from the housing 1 together, thus realizing disassembly. The operation is convenient and the work efficiency of the staff is improved.

[0028] To facilitate the installation of the filter screen 103 by the staff, positioning grooves 108 are provided on the inner walls of both sides of the housing 1, and positioning blocks 109 are provided on both sides of the mounting frame 104. The positioning blocks 109 are slidably connected to the inner walls of the positioning grooves 108. By providing the positioning blocks 109 and the positioning grooves 108, precise positioning of the mounting frame 104 can be achieved, reducing the complexity of installing the filter screen 103 and the time spent on alignment and position adjustment, thereby improving the work efficiency of the staff. Secondly, the positioning blocks 109 and the positioning grooves 108 can provide additional support for the mounting frame 104 to ensure the stability of the filter screen 103 during operation.

[0029] Specifically, the fixing mechanism includes a slider 2 fixedly connected to the clamping block 107, a first elastic member 201 sleeved on the clamping block 107, and an extrusion assembly for pressing the slider 2 against the first elastic member 201. A chute 202 is provided on one side of the accommodating block 110 close to the clamping groove 106. The slider 2 is arranged on one side of the clamping block 107 within the chute 202, and the slider 2 is slidably connected to the inner wall of the chute 202. One end of the first elastic member 201 is fixedly connected to the slider 2, and one end of the first elastic member 201 is fixedly connected to the bottom of the chute 202. Connecting the slider 2 to the inner wall of the chute 202, the chute 202 can limit the degree of freedom of the slider 2, preventing it from rotating or shifting during movement, thereby improving the stability of the slider 2 during movement. At the same time, it can ensure that the first elastic member 201 is evenly stressed, thereby increasing the service life of the first elastic member 201.

[0030] Further, the extrusion assembly includes an extrusion block 203 and a screw 204. An extrusion groove 205 is provided at the top of the chute 202, and the extrusion groove 205 communicates with the chute 202. One side of the clamping block 107 extends into the extrusion groove 205, and a first inclined surface 1071 is provided on the side close to the extrusion groove 205. The first inclined surface 1071 is inclined downward from the side of the clamping block 107 close to the filter screen 103. The extrusion block 203 is arranged in the extrusion groove 205 and is slidably connected to the inner wall of the extrusion groove 205. A second inclined surface 2031 that is slidably connected to the first inclined surface 1071 is provided on the side of the extrusion block 203 close to the clamping block 107. The screw 204 is threadedly connected to the side of the extrusion block 203 away from the first inclined surface 1071, and one end of the screw 204 extends outside the housing 1. The part of the screw 204 in contact with the housing 1 has no threaded section, and the two are rotationally connected by a light system.

[0031] When the staff needs to fix the filter screen 103, the screw 204 can be rotated. Since the extrusion block 203 is slidably connected to the inner wall of the extrusion groove 205, the extrusion groove 205 restricts the radial freedom of the extrusion block 203. Therefore, under the action of the screw 204, the extrusion block 203 moves in a direction away from the screw 204. When the second inclined surface 2031 on the extrusion block 203 contacts the first inclined surface 1071 of the clamping block 107, the clamping block 107 will gradually be squeezed by the second inclined surface 2031 and retract into the chute 202, thereby driving the slider 2 to squeeze the first elastic member 201. At the same time, the other side of the clamping block 107 will extend into the card slot 106, thereby achieving the effect of fixing the filter screen 103.

[0032] When the filter screen 103 needs to be disassembled, the screw 204 can be reversed. The reverse movement of the screw 204 will drive the extrusion block 203 to move in a direction away from the filter screen 103. When the side surface of the extrusion block 203 no longer contacts the chute 202, the first elastic member 201 will reset, thereby causing the slider 2 to move upward. Furthermore, the clamping block 107 extends into the extrusion groove 205. When one side of the clamping block 107 completely extends into the extrusion groove 205, the other side of the clamping block 107 will disengage from the card slot 106. At this time, the staff can pull out the filter screen 103, which is convenient for disassembly work. To facilitate the staff to pull out the filter screen 103, a handle 4 is provided on the side of the installation frame 104 close to the opening 105. A rubber sleeve 401 is provided on the handle 4, and anti-slip patterns are provided on the rubber sleeve 401. The provided handle 4 can facilitate the staff to apply force to pull out the filter screen 103, and the provided rubber sleeve 401 increases the stability and safety when grasping the handle 4.

[0033] To achieve a better filtering effect, it is possible to consider setting multiple clamping blocks 107 and clamping grooves 106, and ensuring that the number of fixing mechanisms corresponds to the number of clamping blocks 107. If multiple clamping blocks 107 and fixing mechanisms are set respectively, the pressing blocks 203 in each fixing mechanism can be connected together by connecting blocks. In this way, by only setting one screw 204, it is possible to simultaneously apply pressure to multiple clamping blocks 107, enabling the clamping blocks 107 to be inserted into the clamping grooves 106 and achieving a firm fixing effect.

[0034] To ensure the sealing performance at the opening 105 of the mounting frame 104 and the housing 1, a moving plate 3 is provided on the side of the clamping block 107 close to the clamping groove 106, and the moving plate 3 is fixedly connected to the clamping block 107. On the side of the moving plate 3 close to the clamping groove 106, a plurality of second elastic members 301 are provided, and one end of each second elastic member 301 is fixedly connected to the moving plate 3. The other end of each second elastic member 301 is fixedly connected to a sealing plate 302. A sealing gasket 303 is provided on the side of the sealing plate 302 close to the clamping groove 106, and the sealing gasket 303 abuts against the top of the mounting frame 104. Both the first elastic member 201 and the second elastic member 301 are selected as cylindrical compression springs.

[0035] By setting the moving plate 3, the second elastic members 301, the sealing plate 302, and the sealing gasket 303, when the clamping block 107 moves under the action of the fixing mechanism, the clamping block 107 will drive the moving plate 3 to move. At the same time, the second elastic members 301, the sealing plate 302, and the sealing gasket 303 also move together with the moving plate 3. When the clamping block 107 is inserted into the clamping groove 106, the surface of the sealing gasket 303 will closely abut against the surface of the mounting frame 104. At this time, the second elastic members 301 are in a compressed state, which ensures that the surface of the sealing gasket 303 forms a tight connection with the surface of the mounting frame 104, effectively preventing the risk of oil leakage at the connection between the mounting frame 104 and the housing 1, and improving the sealing performance inside the housing 1.

[0036] Working principle:

[0037] When the staff needs to fix the filter screen 103, the screw 204 can be rotated. Since the extrusion block 203 is slidably connected to the inner wall of the extrusion groove 205, the extrusion groove 205 restricts the radial freedom of the extrusion block 203. Therefore, under the action of the screw 204, the extrusion block 203 moves away from the screw 204. When the second inclined surface 2031 on the extrusion block 203 contacts the first inclined surface 1071 of the clamping block 107, the clamping block 107 will gradually be squeezed by the second inclined surface 2031 and retract into the sliding groove 202, thereby driving the slider 2 to squeeze the first elastic member 201. At the same time, the other side of the clamping block 107 will extend into the clamping groove 106, thereby achieving the effect of fixing the filter screen 103. While the clamping block 107 is moving, the second elastic member 301, the sealing plate 302, and the sealing gasket 303 also move together with the moving plate 3. When the clamping block 107 is inserted into the clamping groove 106, the surface of the sealing gasket 303 will be in close contact with the surface of the mounting frame 104. At this time, the second elastic member 301 is in a compressed state, which ensures that the surface of the sealing gasket 303 forms a tight connection with the surface of the mounting frame 104, effectively preventing the risk of oil leakage from the connection between the mounting frame 104 and the housing 1 and improving the sealing performance inside the housing 1.

[0038] When the filter screen 103 needs to be disassembled, the screw 204 can be rotated in reverse. The reverse movement of the screw 204 will drive the extrusion block 203 to move away from the filter screen 103. When the side of the extrusion block 203 no longer contacts the sliding groove 202, the first elastic member 201 will reset, causing the slider 2 to move upward. Further, the clamping block 107 extends into the extrusion groove 205. When one side of the clamping block 107 is completely extended into the extrusion groove 205, the other side of the clamping block 107 will disengage from the clamping groove 106. At this time, the staff can extract the filter screen 103 through the handle 4, facilitating the disassembly work.

[0039] Embodiment Two:

[0040] On the basis of Embodiment One, in order to improve the filtering effect of the oil purification device, an adsorption plate 5 is provided inside the housing 1, and the adsorption plate 5 is arranged below the filter screen 103 for secondary filtering of the oil. A fully siliceous molecular sieve matrix adsorbent can be provided on the adsorption plate 5, and groups with chelating effects (such as diaminoglycine groups, pyrrolidine groups, thiourea groups, etc., which are not overly limited in this embodiment) are loaded on the molecules of the fully siliceous molecular sieve, so that the adsorbent has a P-C (polar - chelating) dual selective adsorption effect, and can conveniently, efficiently, and thoroughly remove deterioration products such as acidic, polar, and surface active substances in the oil, making the daily maintenance of the fuel more convenient, faster, safer, more effective, and more economical.

[0041] In addition, the adsorption plate 5 may become saturated after long-term use. For the convenience of the staff to replace it, the solution of Embodiment One can be applied to the adsorption plate 5.

[0042] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
