Description

Technical Field

[0001] This utility model relates to the field of oil processing equipment, and in particular to a high-efficiency oil filter with multi-layer filtration. Background Technology

[0002] Grease plays a role in lubrication and sealing between mechanical parts. It is mainly made of mineral oil and thickener. During the preparation process, it is heated and stirred continuously to achieve the optimal viscosity. Then, it passes through a filtration mechanism to separate the particulate matter and air bubbles mixed in the grease, thereby improving its product quality. Grease filter is a filtration device specifically designed for the grease industry. It can effectively remove impurities and suspended solids from grease, improving the transparency and quality of the grease.

[0003] A search revealed a Chinese patent announcement number: CN217724727U, which discloses a multi-layer high-efficiency grease filter. The filter includes a two-stage filtration mechanism consisting of a vertically distributed first and second filter tank, along with a filter screen and a sieve. It utilizes the gravity of the grease itself to achieve a self-falling filtration capability. In addition, the grease is filtered by a combination of compression filtration and centrifugal filtration mechanisms, resulting in less residual impurities and making it easier to clean and maintain.

[0004] In actual use, the aforementioned grease filter, during the compression filtration process, not only is the grease compressed by the compression platform, but impurities in the grease are also subjected to the compression force as the platform moves downward. If the impurities are located above the filter holes, they will be squeezed into the filter holes and become stuck. Simply shaking or tapping is not enough to quickly remove the impurities, and the filter needs to be disassembled for cleaning, which affects processing efficiency. Therefore, a multi-layer high-efficiency grease filter is proposed to solve the above problems. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figures 1-2 This utility model provides an embodiment of a multi-layer high-efficiency grease filter, including a fixed frame 1, a filter tank 2 detachably connected inside the fixed frame 1, a receiving ring fixedly connected to the lower side of the filter tank 2, a centrifugal filter 3 installed at the bottom of the filter tank 2, and a filter plate 4 fixedly connected to the upper end of the filter tank 2. After the grease enters the filter tank 2, it will undergo preliminary filtration through the filter plate 4 under its own gravity, and then fall into the centrifugal filter 3. The centrifugal filter 3 starts and rotates at high speed, and the grease passes through the centrifugal filter 3. The force continuously impacts the inner wall of the centrifugal filter 3, and through the cutting action of the holes, the air bubbles and impurities are further removed. The separated grease will enter the receiving ring and finally be taken out through the discharge port. This is the existing technology in this field and will not be described in detail here. Several sets of filter holes are opened on the filter plate 4. Several sets of filter holes are arranged in a ring array on the upper surface of the filter plate 4. No filter holes are set on the front side of the upper surface of the filter plate 4. The filter holes in each set are arranged in a linear array. An electric push rod 5 is fixedly connected to the inner top surface of the fixing frame 1.

[0036] Reference Figures 3-5 The bottom end of the electric push rod 5 is fixedly connected to a motor 6, and the bottom output end of the motor 6 is fixedly connected to a pressure plate 7. When the electric push rod 5 is started, it can drive the motor 6 and the pressure plate 7 to move linearly up and down. When it is necessary to pour the oil raw material into the filter tank 2, the electric push rod 5 can be started to drive the pressure plate 7 to move upward and open the top of the filter tank 2. After the raw material is poured out, the electric push rod 5 can be started to drive the pressure plate 7 to move downward and enter the filter tank 2 to squeeze the oil and accelerate the filtration speed of the raw material on the filter plate 4. The bottom surface of the pressure plate 7 is provided with a cleaning groove 8.

[0037] The cleaning tank 8 is equipped with a cleaning unit, which includes a limiting ring 81 fixedly connected inside the cleaning tank 8. An elastic element 82 is fixedly connected to the top surface of the cleaning tank 8, and a limiting plate 83 is fixedly connected to the bottom end of the elastic element 82. Initially, the elastic element 82 is in a compressed state, generating elastic potential energy. The bottom surface of the limiting plate 83 is in contact with the upper surface of the limiting ring 81, and the limiting ring 81 can limit the movement of the limiting plate 83, keeping the elastic element 82 in a compressed state. A cleaning column 84 is fixedly connected to the bottom surface of the limiting plate 83. When the cleaning column 84 moves, it can drive the limiting plate 83 to move synchronously. The bottom end of the cleaning column 84 has an arc-shaped structure, which reduces the contact area with the surface of the filter plate 4. The thickness of the arc is the same as the thickness of the filter plate 4. To reduce friction and wear when the cleaning column 84 moves on the upper surface of the filter plate 4, the size of the cleaning column 84 is adapted to the size of the filter holes. A rubber ring 85 is fixedly connected to the outside of the cleaning column 84. The outer wall of the rubber ring 85 fits against the inner wall of the cleaning groove 8. The rubber ring 85 can seal the gap between the cleaning column 84 and the cleaning groove 8, preventing grease from entering the cleaning groove 8 and causing it to be unable to fall. An exhaust hole 86 is opened on the inner surface of the left side of the cleaning groove 8. The end of the exhaust hole 86 away from the inner wall of the cleaning groove 8 passes through the pressure plate 7. The gas inside the cleaning groove 8 can be exchanged with the outside through the exhaust hole 86, preventing the cleaning groove 8 from being in a closed state, which would affect the vertical linear movement of the cleaning column 84 when the rubber ring 85 is sealed to the outside of the cleaning column 84.

[0038] The number and position of the cleaning grooves 8 are matched with the number and position of the filter holes in a single set on the filter plate 4. When the grease is squeezed to accelerate filtration, some impurities may get stuck in the filter holes or enter the filter holes under the pressure of the pressure plate 7. As the pressure plate 7 continues to move downward, the filter plate 4 will squeeze the cleaning column 84, causing the upper end of the cleaning column 84 to move into the cleaning groove 8 and squeeze the elastic element 82, causing the elastic element 82 to compress and generate elastic potential energy. After the grease is filtered, the motor 6 can be started to drive the pressure plate 7 to enter the filter plate 4. As the filter plate 4 rotates, the cleaning column 84 rotates through each filter hole. When the cleaning column 84 moves above the filter hole, it will be quickly ejected into the filter hole under the elastic potential energy of the elastic element 82, impacting and cleaning the impurities blocking the filter hole, so that the impurities are discharged from the filter hole, avoiding a large number of filter holes being blocked and affecting the filtration efficiency of the filter plate 4. As the pressure plate 7 continues to rotate, the inner wall of the filter hole will squeeze the arc bottom surface of the cleaning column 84, so that the cleaning column 84 is squeezed upward and away from the filter hole, so that the cleaning column 84 can clean all the filter holes.

[0039] A collection unit is provided at the bottom of the pressure plate 7. The collection unit includes a rotating rod 91 and a collection box 92. The rotating rod 91 is fixedly connected to the center of the bottom surface of the pressure plate 7. The collection box 92 is detachably connected to the bottom end of the rotating rod 91. In the initial state, the collection box 92 is located below and in front of the filter plate 4. At this time, no filter holes are provided above the collection box 92 to prevent the filtered grease from entering the collection box 92 and falling down. At the same time, the collection box 92 is located directly below the cleaning column 84. When the pressure plate 7 rotates, the collection box 92 can move with the cleaning column 84, so that the impurities cleaned by the cleaning column 84 can enter the collection box 92 for collection, preventing them from falling into the centrifugal filter 3 and affecting the use of the centrifugal filter 3.

[0040] Reference Figures 6-8An L-shaped mounting bracket 10 is fixedly connected to the upper surface of the collection box 92. When the collection box 92 moves, it can drive the L-shaped mounting bracket 10 to move synchronously. The upper surface of the L-shaped mounting bracket 10 is provided with a slanted slot 11, and the outer surface of the rotating rod 91 is provided with a mounting groove 12. The rear end of the L-shaped mounting bracket 10 is inserted into the interior of the mounting groove 12. The rear end of the L-shaped mounting bracket 10 can move linearly in the front and back direction inside the mounting groove 12. The top surface of the mounting groove 12 is provided with a moving slant groove 13, and a wedge-shaped... Block 14, the bottom end of wedge block 14 is engaged with the inside of inclined slot 11. When wedge block 14 moves obliquely upward along the path of moving inclined slot 13 inside the moving inclined slot 13, it can leave the inside of inclined slot 11, releasing the engagement and fixing of L-shaped mounting bracket 10, so that collection box 92 can be quickly disassembled. A handle 15 is provided on the front side of rotating rod 91. The rear end of handle 15 passes through rotating rod 91. The rear end of handle 15 is fixedly connected to the upper surface of wedge block 14. The operator can pull wedge block 14 to move it by using handle 15.

[0041] When the collection box 92 needs to be disassembled and cleaned, after the filter tank 2 is opened, the handle 15 can be pulled to move the wedge block 14 obliquely upward, away from the inside of the oblique slot 11, releasing the locking and fixing of the L-shaped mounting bracket 10, so that the collection box 92 can be moved forward directly for disassembly. The operation is simple. When the collection box 92 needs to be installed, first pull the handle 15 to move the wedge block 14 upward into the moving oblique slot 13, then insert the rear end of the L-shaped mounting bracket 10 into the mounting slot 12, release the handle 15, so that the wedge block 14 moves downward under the action of gravity and obliquely inserts into the oblique slot 11, quickly locking and fixing the L-shaped mounting bracket 10, and the installation of the collection box 92 can be completed. The operation is simple.

[0042] Working Principle: The oil raw material is poured into filter tank 2. Under its own gravity, the material passes through filter plate 4. At this time, the electric push rod 5 is activated, driving the pressure plate 7 downward to squeeze the material, accelerating filtration on filter plate 4. After preliminary filtration by filter plate 4, the material enters centrifugal filter 3. Centrifugal filter 3 then rotates at high speed, further removing air bubbles and impurities. The separated oil enters the receiving ring and is finally removed through the discharge port. After filtration, the electric push rod 5 can be activated again to drive the pressure plate 7 downward, causing the upper surface of filter plate 4 to press upward against cleaning column 84. When the moving distance of cleaning column 84 is the same as the thickness of filter plate 4, the motor 6 is activated to drive the pressure plate 7 to rotate. As the pressure plate 7 rotates, the cleaning column... The cleaning column 84 moves above the filter holes of the filter plate 4. At this time, under the elastic potential energy of the elastic element 82, the cleaning column 84 is ejected downward and enters the filter hole, knocking the impurities out of the filter hole. As the pressure plate 7 continues to rotate, the cleaning column 84 is squeezed downward by the inner wall of the filter hole and leaves the filter hole, so that the cleaning column 84 can follow the rotation of the pressure plate 7 to clean all the filter holes, avoiding a large amount of impurities clogging the filter holes and affecting the filtration effect of the filter holes. The impurities that are cleaned and dropped will enter the collection box 92 for collection and treatment, preventing impurities from entering the centrifugal filter 3 and affecting the use of the centrifugal filter 3. The operation is simple and can automatically complete the complete cleaning of the filter holes, avoiding the situation where impurities are stuck inside the filter holes and difficult to clean, which would require the filter to be disassembled for cleaning.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
