Description

Technical Field

[0001] This utility model relates to the technical field of lubricating oil treatment equipment, and in particular to an oil tank lubricating oil sedimentation and filtration device. Background Technology

[0002] During the operation of mechanical equipment, lubricating oil plays a vital role in reducing wear, cooling, and sealing against rust. However, as the usage time increases, various impurities inevitably mix into the lubricating oil, such as metal shavings caused by the wear of machine parts, dust from the outside, and gum produced by the oxidation of the oil itself. If these impurities are not removed in time, they will aggravate the wear of moving parts, or even block the oil passages, leading to lubrication failure and seriously affecting the normal operation and service life of the equipment.

[0003] Therefore, to ensure the normal operation of the lubrication system, a filtration device is usually installed in the oil circuit system. Most existing filtration devices use filter screens or filter elements to physically intercept the lubricating oil. This method has a certain filtering effect on larger particles of impurities. However, for the large number of tiny iron filings and other highly abrasive magnetic impurities generated by severe wear of machine parts, the filtration accuracy of traditional filter screens is often limited, making it difficult to completely capture them. These iron filings that slip through the screen will continue to damage the equipment.

[0004] To address this issue, some existing technologies have begun to add magnetic components, such as magnetic drain bolts or magnetic rods, to the bottom of the oil tank or in the oil passage to attract iron filings. However, these magnetic components are usually statically set up, and their adsorption range is limited. They can only passively attract iron filings that happen to flow nearby. For the lubricating oil circulating throughout the entire oil tank, their adsorption efficiency is not high, and a large number of iron filings will still be unable to be effectively removed as the oil circulates. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an oil tank lubricating oil sedimentation and filtration device, which aims to improve the problems of incomplete filtration of lubricating oil impurities and iron filings and inconvenient impurity cleaning in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an oil tank lubricating oil sedimentation and filtration device, comprising: a main oil tank, an auxiliary oil tank, a bracket, a first connecting pipe, a second connecting pipe, and a third connecting pipe; and an adsorption component disposed inside the main oil tank and a filtration component disposed inside the auxiliary oil tank; The adsorption assembly includes an oil tank partition with an overflow port and a magnetic ring on the inner wall of the overflow port; the filtration assembly includes a filter plate and a conical plate, with the filter plate positioned above the conical plate. The bottom of the conical plate is assembled by means of fasteners that are detachably fixed to the bottom of the auxiliary oil tank.

[0007] Preferably, a drain valve is provided on the side wall of the main oil tank.

[0008] Preferably, the magnetic ring is a ring magnet structure.

[0009] Preferably, the tank partition divides the interior of the main tank into two chambers that are interconnected by the overflow port.

[0010] Preferably, the filter assembly includes a plurality of filter plates stacked in a vertical direction.

[0011] Preferably, the conical plate has a funnel-shaped structure with an open top and a narrowing bottom.

[0012] Preferably, the fastener is a nut, and the bottom outer wall of the auxiliary oil tank is provided with a thread that mates with the nut. The nut uses the threaded connection to abut and lock the tapered plate into the auxiliary oil tank.

[0013] Preferably, the bracket is fixedly connected to the outer wall of the main oil tank and the auxiliary oil tank.

[0014] This utility model has the following beneficial effects: 1. This utility model achieves graded and dual purification of lubricating oil through the coordinated operation of the main and auxiliary oil tanks. The lubricating oil first passes through a multi-layer filter plate in the auxiliary oil tank to remove particulate impurities. Then, in the main oil tank, it is forced to flow through an overflow port equipped with a magnetic ring, which effectively adsorbs fine magnetic impurities such as iron filings. This combination of physical filtration and magnetic adsorption results in significant purification, effectively ensuring the cleanliness of the lubricating oil and extending the service life of the equipment.

[0015] 2. In this utility model, the conical plate structure inside the auxiliary oil tank cleverly utilizes the gravity effect to automatically collect the impurities intercepted by the filter to the bottom outlet. The operator only needs to tighten the fasteners at the bottom from the outside to quickly and centrally discharge the impurities. The whole process does not require disassembling complex parts, which greatly simplifies the cleaning and maintenance work and reduces labor intensity and time costs. Attached Figure Description

[0018] 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.

[0019] Reference Figures 1-5 This utility model provides an embodiment of a lubricating oil sedimentation and filtration device, comprising a main oil tank 1, an auxiliary oil tank 4, a support 3, a first connecting pipe 2, a second connecting pipe 5, and a third connecting pipe 9. The main oil tank 1 and the auxiliary oil tank 4 are fixedly connected by the support 3. The support 3 is welded to firmly connect the main oil tank 1 and the auxiliary oil tank 4 into one unit, ensuring the stability of the overall structure. The first connecting pipe 2 is fixedly connected to the wall of the main oil tank 1 and serves as the outlet of the purified lubricating oil. The third connecting pipe 9 is fixedly connected to the wall of the auxiliary oil tank 4 and serves as the inlet of the lubricating oil to be treated. One end of the second connecting pipe 5 is connected to the inner cavity of the auxiliary oil tank 4, and the other end is connected to the inner cavity of the main oil tank 1, for transporting the pre-filtered lubricating oil from the auxiliary oil tank 4 to the main oil tank 1. A drain valve 6 is also fixedly connected to the bottom of the side wall of the main oil tank 1, for discharging the water and impurities deposited at the bottom of the main oil tank 1. An adsorption assembly 7 is fixedly connected inside the main oil tank 1, and a filter assembly 8 is detachably installed inside the auxiliary oil tank 4. The adsorption component 7 includes an oil tank partition 701, which is fixed to the inner wall of the main oil tank 1 by welding. Its structure is stable and it divides the internal space of the main oil tank 1 into two chambers connected by an overflow port 703. The overflow port 703 is opened at the upper part of the oil tank partition 701 and is used to guide the flow path of the oil. A magnetic ring 702 is fixedly installed on the inner wall of the overflow port 703. The magnetic ring 702 is preferably a ring permanent magnet structure, which is fixed by adhesive or snap-fit. It is used to magnetically adsorb the lubricating oil flowing through the overflow port 703 to efficiently remove magnetic impurities such as iron filings. The filter assembly 8 includes multiple filter plates 801, a conical plate 802, and fasteners 803. The filter assembly 8 includes multiple filter plates 801, which are stacked vertically inside the auxiliary oil tank 4 and supported by the upper edge of the conical plate 802, forming a multi-stage filtration structure for filtering particulate impurities in the lubricating oil. The conical plate 802 is a funnel-shaped structure with an open top and a narrow bottom. This structure uses gravity to collect impurities intercepted by the filter plates 801 or settled in the lubricating oil to its bottom. The fastener 803 is preferably a hexagonal nut. The bottom outer wall of the auxiliary oil tank 4 is machined with an external thread that matches the internal thread of the fastener 803. By tightening the fastener 803, the operator can make it press against or release from the lower port outer edge of the conical plate 802, thereby achieving quick locking or releasing of the conical plate 802 so that the collected impurities can be easily discharged.

[0020] Working principle: The lubricating oil to be treated first enters the auxiliary oil tank 4 through the third connecting pipe 9. In the auxiliary oil tank 4, the lubricating oil flows from top to bottom through multiple stacked filter plates 801. This process is used to intercept larger particulate impurities in the lubricating oil. Impurities intercepted by the filter plates 801, as well as impurities that naturally settle in the lubricating oil due to gravity, all fall into the lower conical plate 802. The funnel-shaped structure of the conical plate 802 uses gravity to collect impurities to its bottom. When cleaning is required, the operator can loosen the fasteners 803 from the outside of the auxiliary oil tank 4 to release the conical plate 802 and easily discharge the collected impurities. The lubricating oil that has been preliminarily filtered by the filter plates 801 then flows back to the main oil tank 1 through the second connecting pipe 5. Inside the main oil tank 1, the flow path of the lubricating oil is guided by the tank baffle 701 and forced to flow through the overflow port 703 at the top. As the lubricating oil flows through the overflow port 703, the magnetic ring 702 fixed to its inner wall exerts a magnetic adsorption effect, adsorbing and removing residual fine iron filings and other magnetic impurities in the lubricating oil, thereby achieving deep purification of the lubricating oil. At the same time, water or non-magnetic impurities that may accumulate at the bottom of the main oil tank 1 can be discharged by periodically opening the drain valve 6. Finally, the clean lubricating oil, after being purified by both physical filtration and magnetic adsorption, is output to the equipment that needs lubrication through the first connecting pipe 2, completing the entire filtration and purification process and solving the problems of incomplete filtration and difficulty in removing impurities in the prior art.
