Description

Technical Field

[0001] The utility model relates to the technical field of oil purifiers, in particular to an oil purifier for cleaning lubricating oil. Background Art

[0002] The equipment used to press magnetic cores at the magnetic materials factory is a mechanical, fully automatic powder forming machine. The eccentric connecting rod, driven by the main shaft, moves the upper slide up and down, pressing the magnetic cores. Simultaneously, the die moves downward to synchronize the pressing process, and the ejection cam performs the ejection stroke. Some of these components are located outside the machine. The movement of these components carries powder from the working environment into the lubricating oil tank, where it is then carried to components such as the copper sleeve, gears, ejector rod, and ejector cam. The lubricant is required to be replaced every 2,500 hours, but in reality, approximately 12 kg of magnetic core powder remains in the tank after approximately 1,200 hours. This causes wear on components, and contaminated lubricant scale can easily clog pipelines during transport, causing the equipment to operate without lubrication and further deteriorating the moving parts.

[0003] Wear and tear account for over 60% of equipment maintenance costs. The moving parts of the press are primarily made of 45 alloy steel (hardness HRC50, equivalent to HV513) and brass (hardness around HB80, equivalent to HV85). The powders used are primarily iron-based (hardness HB90, equivalent to HV95), nickel (hardness HRC28, equivalent to HV286), and manganese (Mohs hardness: 6, equivalent to HV714). Abrasive wear between the powder and the components accounts for over 80% of the wear.

[0004] Therefore, how to ensure the cleanliness of lubricating oil and avoid the presence of powder between moving parts to form abrasive wear can reduce the maintenance cost of equipment and is also a technical breakthrough point. Therefore, an oil purifier for cleaning lubricating oil is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] 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. Example

[0025] See also Figure 1 - Figure 4In this embodiment, an oil purifier for cleaning lubricating oil includes an oil purifier body 1, an oil inlet pipe 2 is provided on the upper surface of the oil purifier body 1, a driving motor 3 is provided on one side of the oil inlet pipe 2 on the upper surface of the oil purifier body 1, a driving motor 2 4 is provided on the one side of the driving motor 3 on the upper surface of the oil purifier body 1, an oil cleaning chamber 5 is provided inside the oil purifier body 1 below the oil inlet pipe 2, and a semicircular oil cleaning groove 51 is built in the oil cleaning chamber 5, and the contaminated lubricating oil is input into the semicircular oil cleaning groove 51 through the oil inlet pipe 2. A transmission rod 52 is provided at the center of the oil groove 51. Two or more circular magnetic disks 53 are fixedly and equidistantly provided on the circumferential surface of the transmission rod 52. Elastic scrapers 54 are provided on both sides of each circular magnetic disk 53. Bearings 55 are provided near both ends of the transmission rod 52. A filter plate 56 is provided on one side of the semicircular oil cleaning groove 51. The contaminated lubricating oil level is lower than the upper surface of the semicircular oil cleaning groove 51. The lower half of the circular magnetic disk 53 is located below the contaminated lubricating oil level, while the upper half of the circular magnetic disk 53 is located above the contaminated lubricating oil level.

[0026] The oil inlet pipe 2 delivers oil to the interior of the oil purifier body 1 via an externally provided oil pump. Since the oil pump is conventional, it is not shown in the figure. When the contaminated lubricating oil is delivered to the interior of the semicircular oil cleaning groove 51 provided in the oil cleaning chamber 1 5 via the oil inlet pipe 2, the liquid level of the contaminated lubricating oil is lower than the upper surface of the semicircular oil cleaning groove 51. At this time, the lower half of the circular magnetic disk 53 is located below the liquid level of the contaminated lubricating oil, and the upper half of the circular magnetic disk 53 is located above the liquid level of the contaminated lubricating oil.

[0027] At this time, the transmission rod 52 is driven by the drive motor 1 3, and the drive motor 1 3 and the transmission rod 52 can be connected by a drive component such as a pulley and a gear. The driving method is not unique and the driving method disclosed in the prior art can be fully adopted. In addition, it is not an essential technical feature of the present application, so it is not shown in the figure and will not be described in detail in this embodiment.

[0028] When the driving motor 3 drives the transmission rod 52, the transmission rod 52 can drive the circular disk 53, and the circular disk 53 rotates. Since the main components of the magnetic core material are iron, nickel and manganese elements, the main pollutants in the contaminated lubricating oil are all these materials. They are all paramagnetic materials and can be adsorbed by magnetic materials. Therefore, when the circular disk 53 rotates, the lower half is immersed in the lubricating oil, and the powder inside the lubricating oil is adsorbed onto the circular disk 53, and then the powder is separated by the elastic scraper 54 set on one side of the upper half of the circular disk 53.

[0029] A rotating rod 41 is mounted on the lower surface of the second driving motor 4, a brush 42 is mounted on one end of the rotating rod 41, a collecting box 6 is mounted below the semicircular clean oil groove 51, a second clean oil chamber 7 is mounted on one side of the semicircular clean oil groove 51, an oil purifier tank 8 is mounted below the second clean oil chamber 7, one end of an elastic scraper 54 is mounted on a surface of the disk 53 near the top, and the other end of the elastic scraper 54 is mounted on the upper surface of the collecting box 6 and is lower than the end mounted on one side of the disk 53, a filter screen 71 is mounted on the lower surface of the second clean oil chamber 7, an oil outlet pipe 81 is mounted on the surface of the oil purifier tank 8, and the brush 42 is used to clean the filter screen 71;

[0030] Among them, the powder separated by the elastic scraper 54 can be slid into the collection box 6 for centralized storage by utilizing the inclination angle of the elastic scraper 54, wherein the collection box 6 can be provided with an alarm in the prior art to monitor the amount of separated powder, so as to facilitate the centralized processing in the later stage. After the lubricating oil is purified by the circular magnetic disk 53 for the first time, there is still a lot of non-magnetic materials inside. At this time, the non-magnetic materials can be initially filtered by the filter plate 56, and the filtered lubricating oil will enter the oil purification chamber 2 7, and the lubricating oil in the oil purification chamber 2 7 will pass through the filter screen 71 to filter the remaining non-magnetic materials again. The brush 42 can be driven by the set driving motor 2 4 to sweep away the non-magnetic materials, so that the lubricating oil can flow normally into the oil purifier tank 8, and then the purified lubricating oil is extracted through the oil outlet pipe 81 by the externally provided oil pump of the prior art, thereby ensuring the cleanliness of the lubricating oil of the mechanical fully automatic powder molding machine during the production process, improving production efficiency, improving product qualification rate, ensuring lubrication between moving parts, reducing friction, avoiding abrasive wear, and reducing maintenance costs.

[0031] The working principle of the above embodiment is:

[0032] During use, the contaminated lubricating oil is pumped into the oil cleaning chamber 1 5 by an external oil pump. The transmission rod 52 drives the disk 53, and the lower half of the disk 53 is immersed in the lubricating oil. The powder in the lubricating oil is adsorbed on the disk 53. The powder is then separated by an elastic scraper 54 provided on one side of the upper half of the disk 53. The separated powder can be slid into the collection box 6 for centralized storage by the inclination angle of the elastic scraper 54. The collection box 6 can be provided with an alarm in the prior art to monitor the amount of separated powder, facilitating subsequent centralized processing. The filtered lubricating oil enters the oil cleaning chamber 2 7, and the lubricating oil in the oil cleaning chamber 2 7 is filtered again through the filter 71 to filter the remaining non-magnetic material. The drive motor 2 4 can drive the brush 42 to sweep away the non-magnetic material, allowing the lubricating oil to flow normally into the oil purifier tank 8. The purified lubricating oil is then pumped out through the oil outlet pipe 81 by an external oil pump in the prior art, thereby ensuring the cleanliness of the lubricating oil of the mechanical fully automatic powder forming machine during the production process.

[0033] The installation method, connection method or setting method disclosed in this embodiment are all common mechanical connection methods.

[0034] Any connection method can be implemented as long as it can achieve its beneficial effects. In addition, the electrical components appearing in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Technicians in this field can control the electrical components through simple programming, and the existing disclosed power connection technology is also common knowledge in this field, so its specific structural composition and working principle will not be described in detail in this embodiment.
