Description

Technical Field

[0001] The utility model relates to a filter tank for an oil filter machine, belonging to the field of oil filters. Background Art

[0002] In industrial production, the quality and purity of oil are crucial to the proper operation and service life of equipment. However, during storage, transportation, and use, oil inevitably contaminates with various impurities, such as moisture, metal particles, and oxides. These impurities can severely impact oil performance and even damage equipment. Therefore, filtering and purifying oil to restore or enhance its properties is an essential step in industrial production.

[0003] Chinese patent publication number CN210078943U proposes a filter tank for an oil filter machine. The utility model proposes the problem that "the filter plate in the current existing technology is usually welded to the tank body or fixed with other fasteners such as screws. The installation method is complicated, which makes it inconvenient to disassemble and assemble the filter plate, and cleaning is time-consuming and labor-intensive." It also proposes the following technical solution: "The spherical clamping blocks are matched with the recessed parts at both ends of the filter plate, and the two ends of the filter plate are clamped in the clamping grooves, which is convenient for disassembly and assembly. The top cover of the tank body can be opened, and the filter plate can be removed for easy cleaning, saving time and effort; a soft sealing gasket is provided on the top cover to prevent dust from entering the tank through the gap; the oil inlet pipe is fixed by a flange for easy disassembly." However, in this technical solution, only a single filter plate is used to filter the oil body. When there are many types of impurities in the oil and the particle sizes are widely distributed, the single filter plate cannot completely remove all impurities, especially for small particles and soluble impurities. The removal effect is limited. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-3 A filter tank for an oil filter machine includes a tank body 1, a tank cover 2 fixedly connected to the top of the tank body 1, and an oil inlet pipe 3 fixedly connected to the left side of the tank body 1. Both the left and right sides of the tank body 1 are provided with mounting structures that make it easy to disassemble and assemble the filter element.

[0024] like Figure 1 As shown, the mounting structure includes a shell 4 fixedly connected to the left and right sides of the tank body 1, an elastic telescopic rod 5 fixedly connected to the inner side of the shell 4, a connecting block 6 fixedly connected to the piston rod of the elastic telescopic rod 5, a positioning column 7 fixedly connected to the other side of the connecting block 6, and a filter element assembly passing between the opposite sides of the two positioning columns 7.

[0025] It should be noted that the tank cover 2 is fixedly connected to the tank body 1 by bolts, the left elastic telescopic rod 5 is fixedly connected to the inner left wall of the left shell 4, the right elastic telescopic rod 5 is fixedly connected to the inner right wall of the right shell 4, and the upper surface of the connecting block 6 is fixedly connected with a paddle 8, and the upper surface of the shell 4 is provided with a sliding opening adapted to the paddle 8.

[0026] The filter element assembly includes a mounting frame 9 passed through between opposite sides of the two positioning columns 7, a first filter screen 10 fixedly connected to the inner side of the mounting frame 9, a second filter screen 11, a resin filter element 12 and an activated carbon plate 13. The mesh diameter of the first filter screen 10 is larger than the mesh diameter of the second filter screen 11. The first filter screen 10 is located above the second filter screen 11. The second filter screen 11 is located above the resin filter element 12. The resin filter element 12 is located above the activated carbon plate 13. The resin filter element 12 includes a bracket 1201 fixedly connected to the inner side of the mounting frame 9 and a resin filter element 1202 fixedly connected to the inner side of the bracket 1201. The resin filter element 1202 has good ion exchange performance and can effectively remove harmful substances such as hardness ions and metal ions in the oil body. In addition, the resin filter element 1202 also has a good deacidification effect and can remove acidic substances in the oil and prevent them from corrosive effects on the equipment.

[0027] The inner left wall and the inner right wall of the mounting frame 9 are fixedly connected with a rubber sleeve 14. The right end of the left positioning column 7 sequentially penetrates the left side wall of the tank body 1 and the left side wall of the mounting frame 9 and extends to the inside of the left rubber sleeve 14, and the left end of the right positioning column 7 sequentially penetrates the right side wall of the tank body 1 and the right side wall of the mounting frame 9 and extends to the inside of the right rubber sleeve 14. The rubber sleeve 14 has a certain anti-leakage effect on the mounting frame 9. When the oil enters the inner side of the mounting frame 9, the rubber sleeve 14 prevents the oil from penetrating into the interior of the shell 4 from the joint between the positioning column 7 and the mounting frame 9.

[0028] The working principle of the above embodiment is:

[0029] After the oil enters the interior of the tank body 1 through the oil inlet pipe 3, the oil will be filtered by the filter element assembly. The oil will first pass through the first filter 10. The larger mesh size of the first filter 10 will filter out large particles of impurities in the oil to ensure high flow and faster filtration speed. After passing through the first filter 10, the oil will pass through the second filter 11. The smaller mesh size of the second filter 11 will remove smaller particles and impurities, thereby improving the cleanliness of the oil. After that, the oil will continue to fall and be filtered by the resin filter element 12. The resin filter element 1202 in the resin filter element 12 will remove harmful substances such as hardness ions and metal ions in the oil, further improving the filtering effect. After that, the oil will pass through the activated carbon plate 13. The activated carbon plate 13 will remove organic pollutants and odors in the oil, thereby completing the filtration operation of the oil.

[0030] When the filter element assembly needs maintenance, first, remove the bolts connecting the tank cover 2 to the tank body 1, and then remove the tank cover 2. Then, move the paddle 8. Under the action of the deformation characteristics of the elastic telescopic rod 5, the external force generated by moving the paddle 8 will drive the connecting block 6 to move, and the connecting block 6 will then drive the positioning column 7 to move. The positioning column 7 is then pulled out from the inside of the rubber sleeve 14 of the mounting frame 9, thereby releasing the positioning effect on the mounting frame 9, so that the mounting frame 9 can be quickly and conveniently removed from the inside of the tank body 1.

[0031] It should be noted that the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprises a ..." does not preclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
