Description

Technical Field

[0001] The utility model relates to the technical field of gear oil purification and regeneration, in particular to a gear oil purification system. Background Art

[0002] L-CKD 460# heavy-duty gear oil is suitable for closed gear transmission systems with extremely harsh working conditions and is widely used in metallurgy, cement, electricity, mining, rubber and plastics, fertilizer, coal and other industries. However, the viscosity of the gear oil is too high, which will bring great difficulties to the oil purification work.

[0003] Traditional gear oil filters can only process gear oil waste with lower viscosity, such as 150# gear oil, and are not suitable for processing high-viscosity gear waste oil. The filter unit of the traditional oil filter cannot meet the purification needs of high-viscosity gear oil, resulting in many problems such as difficulty in extracting high-viscosity gear oil, poor purification effect, low purification efficiency, and inability to reuse purified oil normally, making it difficult to purify high-viscosity gear waste oil.

[0004] Therefore, in view of the shortcomings of the above scheme in actual production and implementation, it has been revised and improved. At the same time, in the spirit and concept of seeking excellence, with the assistance of professional knowledge and experience, and after many ingenuity and experiments, a gear oil purification system is provided to solve the problem that the existing purification technology cannot handle high-viscosity gear waste oil and is difficult to purify high-viscosity gear waste oil. Utility Model Content

[0008] As a preferred embodiment, a sewage ball valve is provided at the bottom of the waste oil storage tank.

[0009] The waste oil storage tank is used for the transfer and storage of high-viscosity waste gear oil. After the high-viscosity waste gear oil has been allowed to stand, it can be discharged from the drain valve to preliminarily remove the clear water and other settleable impurities in the high-viscosity waste gear oil.

[0010] As a preferred embodiment, the applicable range of the viscosity of the conveyed material of the high-viscosity gear oil pump is 5-1500 cSt, which can meet the conveying needs of different types of high-viscosity waste gear oils.

[0011] This solution introduces an electromagnetic heater to efficiently heat high-viscosity waste gear oil, improve the fluidity of the waste oil, and provide stable temperature conditions for subsequent purification.

[0012] Activated carbon adsorption filtration device Activated carbon adsorbs pollutants in high-viscosity waste gear oil, thereby improving the oxidation stability and other properties of the lubricating oil.

[0013] As a preferred embodiment, the filter material of the composite grid filter device is a sheet-like adsorption material, the sheet-like adsorption material is used for dehydration, decontamination and decolorization, and each sheet-like adsorption material is arranged in a grid.

[0014] This adsorption material integrates the three functions of dehydration, impurity removal and decolorization to achieve the effect of composite filtration; it adopts a grid arrangement mode, with high filtration efficiency, large dirt holding capacity, and convenient replacement, which can realize timely replacement of pre-filter materials and recycling of post-filter materials.

[0015] As a preferred embodiment, the supplementary filtering device has a built-in metal titanium rod with a filtering accuracy of 10-5 μm, which can reduce the filtering pressure of subsequent units.

[0016] As a preferred embodiment, the filter bag in the precision impurity removal filter device is made of a mixture of glass fiber base cloth and chemical fiber through needle punching, forming a three-dimensional microporous structure in space for deep filtration.

[0017] The precision impurity filter device designed in this way can perform both surface filtration and deep filtration, thereby achieving an oil output mechanical impurity index of less than 0.01%, meeting the new oil standard.

[0018] The purification method adopted by this purification system is pure physical purification, which does not involve the addition of any chemical agents. While restoring the bad indicators of high-viscosity gear oil, it does not damage its good indicators.

[0019] This purification system can be installed on a mobile cart to achieve convenient movement of the equipment.
