Description

Technical Field

[0001] The utility model belongs to the field of filtering equipment, in particular to an impact-resistant hydraulic lubricating oil filter. Background Art

[0002] Hydraulic oil is a specialized fluid used in hydraulic systems to transfer energy, lubricate components, and provide sealing and cooling functions. Current hydraulic oil filters suffer from several shortcomings. First, most lack impact-resistant structures, a major drawback. In practical applications, hydraulic oil filters may be subject to various impacts during use. Without these impact-resistant structures, filters are easily damaged by these impacts, resulting in reduced filtration efficiency or even failure. These shortcomings are primarily due to design deficiencies that fail to adequately account for the impacts experienced in actual operating environments. Conventional solutions address this shortcoming by strengthening and sealing the filter housing. These measures include using stronger materials and increasing the thickness of the housing to improve impact resistance. However, this approach has drawbacks. On the one hand, it increases the filter's cost and weight; on the other, it may affect the filter's heat dissipation performance and ease of installation. While the hydraulic oil filter's built-in housing provides some impact protection, relying solely on the housing may not be sufficient in harsh operating environments, such as those with frequent line delivery and high impact. Designing a specialized impact-resistant structure can better withstand these impacts, improving the filter's reliability and stability, and extending its service life. Therefore, a new structure is needed to address these technical issues. Utility Model Content

[0019] 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.

[0020] See also Figures 1 to 4 The utility model provides a technical solution: an impact-resistant hydraulic lubricating oil filter, comprising: a housing component and a filter component 200, the outer surface and the interior of the housing component are both equipped with the filter component 200, the housing component comprises: a housing body 100, a fixing rod 140 and a fixing member 150, the lower surface of the housing body 100 is equipped with a supporting leg, the housing body 100 comprises: a protective layer 101, a honeycomb layer 102 and a foam layer 103, the honeycomb layer 102 and the foam layer 103 are installed between the two protective layers 101 Layer 103, a fixing rod 140 is installed inside the shell body 100, and the filter assembly 200 includes: a pump 210, a delivery pipe 1 220, a delivery pipe 2 230 and a filter element 240. The pump 210 is installed on the outer surface of the shell body 100 through the mounting plate 120, the delivery pipe 1 220 is installed at the outlet end of the pump 210, and the delivery pipe 2 230 is installed on the outer surface of the delivery pipe 1 220. A plurality of filter elements 240 are installed inside the shell body 100, and a fixing part 150 is installed between every two filter elements 240.

[0021] See also Figures 1 to 4 As a first embodiment of the present invention: a mounting plate 120 is mounted on the lower edge of the rear surface of the housing body 100, and a plurality of supporting legs are mounted on the mounting plate 120 and the lower surface of the housing body 100. The upper surface of the housing body 100 is open, and three fixing rods 140 are evenly mounted on the front inner wall and the rear inner wall of the housing body 100;

[0022] The two ends of the fixing rod 140 are respectively connected to the left inner wall and the right inner wall of the outer shell 100. The outer shell 100 is composed of a protective layer 101, a foam layer 103, a honeycomb layer 102 and a protective layer 101 from the outside to the inside. The two protective layers 101 have the same structure. The materials of the protective layer 101, the foam layer 103 and the honeycomb layer 102 are steel plate, polyurethane foam and aluminum honeycomb panel respectively.

[0023] During use, when the outer shell 100 of the filter device is impacted, the internal protective layer 101 of the outer shell 100 first blocks the impact effect, and then transmits the subsequent impact effect to the foam layer 103, the honeycomb panel and the second protective layer 101. At this time, the outermost protective layer 101 serves as the first layer of protection to resist direct external impact and scratches. They form the first line of defense of the filter to prevent external objects from causing damage to the internal structure. When the impact force is transmitted to the foam layer 103, the foam material will deform and absorb the impact energy, further reducing the impact force transmitted to the internal filter element and other key components. The foam layer 103 The energy absorption effect of 03 can effectively buffer the impact and protect the internal structure of the filter. Subsequently, the honeycomb layer 102 can convert the concentrated impact force into smaller forces in multiple directions, thereby reducing the impact on internal components. This effect of dispersing the impact force can greatly improve the filter's impact resistance and reduce the risk of damage caused by impact. During use, the impact force on the filter element is greatly reduced through the protection of the multi-layer impact-resistant structure, which can significantly extend the service life of the filter element, reduce the frequency of replacement, and reduce maintenance costs. The filter element works in a relatively stable environment and can better exert its filtering performance and maintain the cleanliness of the hydraulic lubricating oil.

[0024] See also Figures 1 to 4 As a second embodiment of the present invention: a pump 210 is mounted on the upper surface of the mounting plate 120 via a mounting member 130. The pump 210 is provided with two outlet ends, each of which is equipped with a first delivery pipe 220. Three second delivery pipes 230 are evenly mounted on the outer surface of the first delivery pipe 220. The end of the second delivery pipe 230 away from the first delivery pipe 220 passes through the housing body 100 and is connected to the filter element 240.

[0025] Three groups of filter elements 240 are installed in the housing body 100, with each group of two. A fixing member 150 is installed between the top filter element 240 and the middle filter element 240, and a fixing member 150 is installed between the middle filter element 240 and the bottom filter element 240. The multiple fixing members 150 have the same structure.

[0026] The outlet end of the filter element 240 is arranged on the front surface of the housing body 100, and the multiple groups of filter elements 240 have the same structure;

[0027] During use, the hydraulic lubricating oil to be cleaned is pumped into the interior of the delivery pipe 1 220 by the pump 210, and then the delivery pipe 1 220 delivers the hydraulic lubricating oil to the interior of the delivery pipe 230, and then the delivery pipe 230 delivers the hydraulic lubricating oil to the interior of the filter element 240, and then the filter element 240 filters the hydraulic lubricating oil and finally discharges it, thereby completing the hydraulic lubricating oil filtration process (the specific structure of the filter element 240 is not detailed here);

[0028] When the shell body 100 is impacted, the shell body 100 first buffers the impact through the first embodiment step, and then the fixing rod 140 inside the shell body 100 and the fixing rod 140 provide a support for the subsequent impact effect. The fixing rod 140 provides a stable support structure for the inside of the filter, which can prevent the shell body 100 from excessive deformation when impacted and maintain the overall shape and size of the filter stable. At the same time, the fixing part 150 plays a role of spacing and fixing between each two groups of filter elements 240, which can ensure that the filter element 240 maintains the correct position inside the filter and prevents the filter element 240 from being displaced or colliding with each other under impact and vibration. The fixing part 150 and the fixing rod 140 can play a good anti-impact effect together with the shell body 100 itself.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
