Description

Technical Field

[0001] This utility model belongs to the field of filter technology, specifically relating to a spin-on plate high-pressure filter. Background Technology

[0002] Spin-on plate high-pressure filters play a vital role in many industrial applications, especially in hydraulic systems, lubrication systems, and other applications requiring precision filtration. The main features of these filters are that they can be screwed into the system for easy installation and replacement, while they can effectively filter impurities in fluids under high pressure, ensuring the normal operation of the system.

[0003] Chinese Patent Application No. 202321072652.7 discloses a spin-on plate high-pressure filter, including a filter head and a filter cartridge connected to the bottom of the filter head. The filter head has an oil inlet channel and an oil outlet channel. A filtration device for filtration is connected inside the filter cartridge, and a bypass valve is connected inside the oil inlet channel. An adapter is connected between the filter cartridge and the filter head, and the filtration device is rotatably connected between the adapter and the filter cartridge. Compared with the traditional complex structure, this solution is not only simple in structure but also easy to operate. At the same time, the simplicity of the structure reduces production costs and production processes, which helps to improve market acceptance. The filtration device is rotatably connected to the adapter and the filter cartridge. The filter element and the filter cartridge rotate with the oil pressure pulse, thereby reducing the impact of the oil pressure pulse on the filtration device and the filter cartridge, thus improving the service life of the filter.

[0004] The aforementioned disclosed patents have the following problems when used:

[0005] 1. The filter uses a filter element and filter cartridge for filtration. However, the filter element and filter cartridge are usually designed as an integrated unit and are replaced at the same time when the filter is replaced. Since the filter cartridge is made of fixed material and the filter element is a consumable material, replacing them at the same time will lead to waste of resources and reduce the utilization rate of the internal components of the filter.

[0006] 2. The filter cartridge has a first gap channel on its inner surface, but no protective components are provided on the outside of the cartridge. When it is bumped, the surface of the cartridge may be directly damaged, and the oil will overflow, causing waste and environmental pollution. At the same time, when the oil temperature inside the filter is too high, it will damage the filter element and reduce the service life of the filter. Utility Model Content

[0022] 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.

[0023] Example 1

[0024] Please see Figure 1-4The present invention provides the following technical solution: a spin-on plate high-pressure filter, comprising a filter head 1, an oil inlet channel 2 inside the filter head 1, an oil outlet channel 3 at the bottom of the oil inlet channel 2, a bypass valve 12 on one side of the oil outlet channel 3, a connecting seat 4 at the bottom of the oil outlet channel 3, a second gap channel 6 on one side of the connecting seat 4, a filter cartridge 5 on one side of the second gap channel 6, a first gap channel 7 on one side of the filter cartridge 5, a filter element 9 on one side of the first gap channel 7, a filter cartridge 10 on one side of the filter element 9, an adsorption component 8 inside the filter element 9, and a protective component 11 on the surface of the filter cartridge 5.

[0025] Specifically, the adsorption assembly 8 includes a through hole 81, a mounting plate 82, a torsion ring 83, a connecting plate 84, a threaded groove 85, a threaded block 86, an adsorption cylinder 87, a magnet block 88, a spring cylinder 89, a spring 890, and a limiting plate 891. The surface of the filter cylinder 10 is provided with a mounting plate 82, the interior of the mounting plate 82 is provided with a threaded groove 85, and one side of the threaded groove 85 is provided with a through hole 81. The surface of the mounting plate 82 is provided with a connecting plate 84, the top surface of the connecting plate 84 is provided with a torsion ring 83, the interior of the threaded groove 85 is provided with an adsorption cylinder 87, the surface of the adsorption cylinder 87 is provided with a threaded block 86, the interior of the adsorption cylinder 87 is provided with a magnet block 88, the bottom of the adsorption cylinder 87 is provided with a spring cylinder 89, the interior of the spring cylinder 89 is provided with a spring 890, and the top of the spring 890 is provided with a limiting plate 891.

[0026] By adopting the above technical solution, when the filter is working, rotating the torsion ring 83 fixed at the top of the adsorption cylinder 87 further drives the connecting plate 84 at the bottom of the torsion ring 83 and the adsorption cylinder 87 to rotate, so that the threaded block 86 on the surface of the adsorption cylinder 87 and the threaded groove 85 inside the mounting plate 82 mesh with each other. When the adsorption cylinder 87 is fixed inside the mounting plate 82, it can complete the rotation. When the oil enters the filter cylinder 10, it will first reduce the oil pulse when it comes into contact with the mounting plate 82, further protecting the stability of the internal structure of the filter and extending the service life. When the oil further enters the surface of the adsorption cylinder 87 through the through hole 81 inside the mounting plate 82, the threaded block 86 on the surface of the adsorption cylinder 87 and the threaded groove 85 inside the adsorption cylinder 87 mesh with each other. The magnetic block 88 adsorbs metallic impurities in the oil, fixing them to the surface of the adsorption cylinder 87. This prevents the metallic impurities from clogging the filter cylinder 10, which would otherwise affect the filtration effect and require frequent replacement of the filter cylinder 10, wasting resources and reducing the utilization rate of the filter's internal components. When replacing the filter element 9, simply reverse the torsion ring 83, remove the adsorption cylinder 87, clean off the surface metallic impurities, and it can be reinstalled and used. This avoids the problem of frequent replacement of the filter cylinder 10, solves the problem of resource waste caused by the low utilization rate of the filter's internal components, and also facilitates disassembly and installation, greatly improving the practicality of the filter.

[0027] Specifically, limit blocks are provided on both sides of the mounting plate 82 at the contact points with the surface of the filter cartridge 10.

[0028] By adopting the above technical solution, the position of the mounting plate 82 is prevented from shifting when the filter is in use, and the adsorption cylinder 87 is prevented from shifting with the position of the mounting plate 82, which would affect the filtration effect of the adsorption cylinder 87 and reduce the stability of the component.

[0029] Specifically, a limit post is provided at the contact point between the bottom of the spring 890 and the surface of the spring cylinder 89.

[0030] By adopting the above technical solution, the spring 890 is prevented from falling out of its fixed position when compressed and stretched, thus avoiding affecting the stability of the component.

[0031] In this embodiment, during filter operation, the rotating torsion ring 83 fixed at the top of the adsorption cylinder 87 further rotates the connecting plate 84 at the bottom of the torsion ring 83 and the adsorption cylinder 87, causing the threaded block 86 on the surface of the adsorption cylinder 87 and the threaded groove 85 inside the mounting plate 82 to mesh with each other. The rotation is completed when the adsorption cylinder 87 is fixed inside the mounting plate 82. When oil enters the filter cylinder 10, it first reduces oil pulses upon contact with the mounting plate 82, further protecting the internal structure of the filter and extending its service life. As the oil further enters the surface of the adsorption cylinder 87 through the through hole 81 inside the mounting plate 82, the magnetic block 88 inside the adsorption cylinder 87 adsorbs metal impurities in the oil, fixing them to the surface of the adsorption cylinder 87. This prevents metal impurities from clogging the filter cylinder 10, which would affect the filtration effect and force the filter cylinder 10 to... Frequent replacement of the filter cartridge 10 wastes resources and reduces the utilization rate of internal components. When replacing the filter cartridge 9, simply reverse the torsion ring 83, remove the adsorption cylinder 87, clean off any metal impurities on the surface, and it can be reinstalled and used. This avoids the problem of frequent replacement of the filter cartridge 10, solves the problem of resource waste caused by the low utilization rate of internal components, and also facilitates disassembly and installation, greatly improving the practicality of the filter. By setting limit blocks on both sides of the mounting plate 82 at the contact points with the surface of the filter cartridge 10, the position of the mounting plate 82 is prevented from shifting during the use of the filter, preventing the adsorption cylinder 87 from shifting with the position of the mounting plate 82, affecting the filtration effect of the adsorption cylinder 87, and reducing the stability of the component. By setting limit posts at the contact points between the bottom of the spring 890 and the surface of the spring cylinder 89, the spring 890 is prevented from falling out of its fixed position when compressed and extended, thus preventing the stability of the component from being affected.

[0032] Example 2

[0033] The difference between this embodiment and Embodiment 1 is that, specifically, the protective component 11 includes a buffer cotton 111, a threaded sleeve 112, a threaded head 113, a reinforcing hoop 114, a protective shell 115, a heat sink 116, and a heat-conducting plate 117. The surface of the filter cartridge 5 is provided with a threaded sleeve 112, the surface of the threaded sleeve 112 is provided with a threaded head 113, one side surface of the threaded head 113 is provided with a reinforcing hoop 114, the bottom of the threaded head 113 is provided with a protective shell 115, the bottom of the protective shell 115 is provided with a heat sink 116, one side surface of the heat sink 116 is provided with a heat-conducting plate 117, and the top of the heat-conducting plate 117 is provided with a buffer cotton 111.

[0034] By adopting the above technical solution, when the filter is in use, the protective shell 115 is fitted onto the surface of the filter cartridge 5. At the same time, the protective shell 115 is rotated so that the threaded head 113 on the top of the protective shell 115 and the threaded sleeve 112 fixed on the surface of the filter cartridge 5 are engaged and tightened. The protective shell 115 is reinforced by the reinforcing hoop 114. The protective shell 115 can effectively protect the filter cartridge 5 from unnecessary damage during use, thereby avoiding resource waste and environmental pollution caused by oil leakage due to filter cartridge 5 breakage. The buffer cotton 111 can prevent the external impact of the filter cartridge 5 from affecting the internal structural stability of the filter. The heat-conducting plate 117 can effectively conduct heat out of the oil inside the filter. The heat dissipation plate 116 further dissipates heat from the oil. This solves the problem that the filter cartridge 5 may be damaged by bumps during use, resulting in oil leakage and thus causing resource waste and environmental pollution. It also optimizes the heat dissipation performance of the filter, avoids the filter element 9 from being damaged by excessively high oil temperature, and improves the practicality of the filter.

[0035] Specifically, the surface of the threaded sleeve 112 meshes with one side of the threaded head 113, and an arc-shaped groove is provided at the contact point between the reinforcing hoop 114 and the surface of the threaded head 113.

[0036] By adopting the above technical solution, the mutual meshing of the threaded sleeve 112 and the threaded head 113 improves the convenience of the component during use. By setting the arc groove, the reinforcing hoop 114 can be fixed in the arc groove, continuously and stably playing a fastening role and improving the stability of the component.

[0037] In this embodiment, during use: the protective shell 115 is fitted onto the surface of the filter cartridge 5, and the protective shell 115 is rotated to engage and secure the threaded head 113 on the top of the protective shell 115 with the threaded sleeve 112 fixed to the surface of the filter cartridge 5. The protective shell 115 is reinforced by a reinforcing hoop 114. The protective shell 115 effectively protects the filter cartridge 5 from unnecessary damage during use, thus preventing resource waste and environmental pollution caused by oil leakage due to filter cartridge 5 breakage. The buffer cotton 111 prevents external impacts on the filter cartridge 5 from affecting the internal structural stability of the filter. The heat-conducting plate 117 effectively dissipates heat from the oil inside the filter, further facilitating heat dissipation. The plate 116 dissipates heat from the oil, solving the problem that the filter cartridge 5 may be damaged by impacts during use, leading to oil leakage, resource waste, and environmental pollution. It also optimizes the heat dissipation performance of the filter, preventing the filter element 9 from being damaged by excessively high oil temperature, thus improving the practicality of the filter. The surface of the threaded sleeve 112 meshes with the surface of one side of the threaded head 113, and the reinforcing hoop 114 has an arc-shaped groove at the contact point with the surface of the threaded head 113. This meshing between the threaded sleeve 112 and the threaded head 113 during use improves the ease of use of the component. By setting the arc-shaped groove, the reinforcing hoop 114 can be fixed in the arc-shaped groove, continuously and stably performing a fastening function and improving the stability of the component.

[0038] The structure and operating principle of the connecting seat 4 and bypass valve 12 in this utility model have been disclosed in a spin-on plate high-pressure filter disclosed in Chinese patent application number 202321072652.7.

[0039] The working principle and usage process of this utility model: This utility model is designed for adjusting a spin-on plate high-pressure filter. When the filter is in operation, rotating the torsion ring 83 fixed at the top of the adsorption cylinder 87 further drives the connecting plate 84 at the bottom of the torsion ring 83 and the adsorption cylinder 87 to rotate. This causes the threaded block 86 on the surface of the adsorption cylinder 87 and the threaded groove 85 inside the mounting plate 82 to mesh with each other. The rotation is completed when the adsorption cylinder 87 is fixed inside the mounting plate 82. When oil enters the filter cylinder 10, contact with the mounting plate 82 first reduces oil pulses, further protecting the internal structure of the filter and extending its service life. As the oil further enters the surface of the adsorption cylinder 87 through the through hole 81 inside the mounting plate 82, the magnetic block 88 inside the adsorption cylinder 87 adsorbs metal impurities in the oil, fixing them to the surface of the adsorption cylinder 87. This prevents metal impurities from clogging the filter cylinder 10, which would affect the filtration effect and cause blockage of the filter cylinder. The frequent replacement of filter cartridge 10 wastes resources and reduces the utilization rate of internal components. When replacing filter cartridge 9, simply reverse the torsion ring 83, remove the adsorption cylinder 87, clean off any metal impurities, and it can be reinstalled and used. This avoids the problem of frequent filter cartridge 10 replacements, solving the resource waste caused by low utilization of internal components. It also facilitates disassembly and installation, greatly improving the practicality of the filter. By setting limiting blocks on both sides of the mounting plate 82 at the contact points with the surface of the filter cartridge 10, the position of the mounting plate 82 is prevented from shifting during filter use, thus preventing the adsorption cylinder 87 from shifting with the position of the mounting plate 82, affecting the filtration effect of the adsorption cylinder 87, and reducing the stability of the component. By setting limiting posts at the contact points between the bottom of the spring 890 and the surface of the spring cylinder 89, the spring 890 is prevented from detaching from its fixed position when compressed and extended, thus ensuring the stability of the component. This utility model is an adjustment for spin-on plate high-pressure filters.When using this filter, the protective shell 115 is fitted onto the surface of the filter cartridge 5. Simultaneously, rotating the protective shell 115 causes the threaded head 113 on the top of the protective shell 115 to engage and tighten with the threaded sleeve 112 fixed to the surface of the filter cartridge 5. The protective shell 115 is reinforced by a reinforcing hoop 114. The protective shell 115 effectively protects the filter cartridge 5 from unnecessary damage during use, thus preventing resource waste and environmental pollution caused by oil leakage due to filter cartridge 5 breakage. The buffer cotton 111 prevents external impacts on the filter cartridge 5 from affecting the internal structural stability of the filter. The heat-conducting plate 117 effectively dissipates heat from the oil inside the filter, and the heat is further dissipated by the heat sink 116. The oil is used for heat dissipation, solving the problem of oil leakage caused by potential damage to the filter cartridge 5 due to impacts during use, which would lead to resource waste and environmental pollution. It also optimizes the filter's heat dissipation performance, preventing overheating and damage to the filter element 9, thus improving the filter's practicality. The interlocking of the threaded sleeve 112 and one side of the threaded head 113, along with the arc-shaped groove at the contact point between the reinforcing hoop 114 and the threaded head 113, enhances the ease of use. The arc-shaped groove also allows the reinforcing hoop 114 to be securely fixed within it, providing a continuous and stable fastening effect and improving the overall stability of the component.
