Description

Technical Field

[0001] This utility model relates to the field of mineral oil filtration, and in particular to a mineral oil filtration regeneration device. Background Technology

[0002] Mineral oil filtration and regeneration is a complex and delicate process, typically involving key steps such as pretreatment, filtration, and subsequent refining. Pretreatment aims to remove impurities from the oil, creating favorable conditions for subsequent filtration; the filtration stage focuses on separating solid particles from the oil; and refining further improves the oil quality. When pretreating mineral oil to filter solid particles, a single filtration method is insufficient due to the varying particle sizes and properties of the impurities in the oil. Therefore, a multi-stage filtration approach is necessary to progressively improve filtration precision.

[0003] In traditional mineral oil filtration and regeneration devices, during the pretreatment stage of solid particle filtration, mineral oil has a high viscosity due to its inherent properties. During filtration, the high-viscosity mineral oil easily adheres to the filter screen surface. As filtration continues, the amount of oil adhering to the filter screen surface gradually increases, hindering the normal passage of oil and thus reducing filtration efficiency to some extent.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0017] Example: This example provides a mineral oil filtration and regeneration device, see [link to example]. Figure 1-4 Specifically, it includes a filter box 1, with an inlet pipe 11 and an outlet pipe 12 installed at the upper and lower ends of the filter box 1, respectively. Inside the filter box 1, from top to bottom, there are a heating component 2, an inclined coarse filter component 4, and a V-shaped fine filter component 6. The heating component 2 is located below the inlet pipe 11, and the outlet pipe 12 is located below the fine filter component 6.

[0018] In this embodiment, the mineral oil filtration and regeneration device mainly consists of a filter box 1 forming the main frame. An inlet pipe 11 and an outlet pipe 12 are respectively installed at the upper and lower ends of the filter box 1 to facilitate the entry and exit of mineral oil. Inside the filter box 1, from top to bottom, a heating assembly 2, an inclined coarse filter assembly 4, and a V-shaped fine filter assembly 6 are arranged sequentially. The heating assembly 2 heats the mineral oil to reduce its viscosity, the coarse filter assembly 4 initially filters out larger solid particles, and the fine filter assembly 6 further refines the filtration, ultimately allowing the treated mineral oil to be discharged from the outlet pipe 12.

[0019] In the specific implementation process, such as Figure 1 and Figure 2As shown, the heating assembly 2 includes a rectangular box 21 fixedly installed inside the filter box 1. A heating tube 22 is fixedly installed in the interlayer of the rectangular box 21. A heater 23 is fixedly installed at the lower end of the rectangular box 21. The heating tube 22 is fixedly connected to the heater 23. A feeding component is installed at the discharge port of the rectangular box 21.

[0020] In this embodiment, the rectangular box 21 forms a heating chamber, allowing the mineral oil to remain and be heated evenly. The heating tube 22, also known as a heating element or tubular electric heater element, heats up when energized. It consists of a coiled heating wire placed inside a metal tube, a prior art technique. Heat is conducted to the mineral oil inside the rectangular box 21 through its walls. The heater 23 is the control center, connected to an external power source via wires. It supplies power to the heating tube 22 and provides temperature control, ensuring the oil temperature remains stable at the set value. When energized, the heater 23 generates energy, which is transferred to the heating tube 22. The heating tube 22 heats up, raising the temperature inside the rectangular box 21 and thus heating the mineral oil. When the feeder is opened, the heated mineral oil flows out from the outlet of the rectangular box 21 and enters the next processing stage. Preheating the mineral oil effectively reduces its viscosity, a crucial prerequisite for efficient subsequent filtration. The jacketed heating method allows for even heat distribution, preventing localized overheating.

[0021] In the specific implementation process, such as Figure 1 and Figure 2 As shown, the unloading component includes a baffle 31 that is slidably installed at the bottom of the outlet of the rectangular box 21. A cylinder 32 is fixedly installed on the lower surface of the rectangular box 21. The output end of the cylinder 32 is fixedly connected to the baffle 31. A guide plate 3 is installed at the bottom of the inner cavity of the rectangular box 21. The guide plate 3 is used to guide the mineral oil in the rectangular box 21 to the outlet of the rectangular box 21.

[0022] In this embodiment, cylinder 32, model (AIRTAC), serves as the power source. Its extension and retraction at the output end drives the baffle 31 to slide, controlling the opening and sealing of the discharge port. The guide plate 3 guides the mineral oil from the bottom of the rectangular box 21 to the discharge port, ensuring smooth flow and preventing accumulation inside the box. Controlling the opening of the rectangular box 21's discharge port allows the heated mineral oil to stably enter the subsequent filtration stage, ensuring the continuity and stability of the entire filtration process.

[0023] In the specific implementation process, such as Figure 1 and Figure 3 As shown, the coarse filter assembly 4 includes a fixed frame 41 that is installed at an angle inside the filter box 1. A filter screen 42 is fixedly installed inside the fixed frame 41, and a collection element is provided at one end of the fixed frame 41.

[0024] In this embodiment, the fixing frame 41 provides structural support for the filter screen 42 and fixes it in the housing at a specific tilt angle. The core filter medium of the filter screen 42 has a large pore size, which is used to screen out larger mechanical impurities. It can effectively remove larger solid particulate impurities in mineral oil, reduce the filtration burden of the subsequent fine filter assembly 6, improve the overall filtration efficiency, and the tilted setting makes it easy for impurities to slide down to the collection device at the end by gravity.

[0025] In the specific implementation process, such as Figure 1 and Figure 3 As shown, the collection component includes a support plate 5 fixedly installed on the inner wall of the filter box 1, a collection box 51 is placed on the support plate 5, the upper end of the collection box 51 is attached to the end of the filter screen 42, and a cleaning window 52 for removing the collection box 51 is provided on the side of the filter box 1.

[0026] In this embodiment, the support plate 5 supports the collection box 51. The collection box 51 directly holds coarsely filtered impurities and is a movable container. The cleaning window 52 provides a maintenance channel, allowing for the cleaning of impurities without opening the entire top cover of the filter box 1.

[0027] In the specific implementation process, such as Figure 1 and Figure 4 As shown, the fine filtration assembly 6 includes two support seats 61 fixedly installed at the bottom of the inner cavity of the filter box 1. A driven roller 62 and a take-up roller 63 are rotatably mounted on the two support seats 61 respectively. A filter paper roll 64 is sleeved on the driven roller 62. The end of the filter paper roll 64 is connected to the take-up roller 63. A baffle 65 is fixedly installed inside the filter box 1. The baffle 65 is in contact with the upper surface of the filter paper roll 64. The baffle 65, the driven roller 62 and the take-up roller 63 are arranged in a triangle. A motor 66 is fixedly installed on one support seat 61. The output end of the motor 66 is connected to the take-up roller 63.

[0028] In this embodiment, the support base 61 supports the frame of the entire fine filtration mechanism. The driven roller 62 stores unused fresh filter paper rolls 64. The take-up roller 63 rotates under the drive of a motor 66 (DC motor 5840-31ZY), winding up the dirty filter paper that has already adsorbed fine impurities. The filter paper roll 64, a high-precision filtration medium, is responsible for trapping micron-sized fine particles. Its V-shaped design increases the filtration area and acts as a guide pipe 12 to "gather oil." The baffle 65 is a key component. It presses against the filter paper, utilizing the paper's flexibility to allow it to naturally droop, forming a V-shaped groove, increasing the effective filtration area. This achieves fine filtration of mineral oil, effectively removing smaller solid particulate impurities and improving the purity of the mineral oil. The automatic replacement of the filter paper roll 64 is achieved through the motor 66, reducing manual operation and improving filtration efficiency and the automation level of the device.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
