Description

Technical Field

[0001] The utility model belongs to the field of filtering devices, in particular to a lubricating oil filtering device. Background Art

[0002] Lubricating oil filtration is a key link to ensure the cleanliness of lubricating oil and maintain the normal operation of equipment. Through filtration, solid particles, moisture, gas and other impurities in lubricating oil can be effectively removed, thereby extending the service life of lubricating oil, reducing equipment wear, and improving equipment performance and reliability.

[0003] Lubricating oil filtration is divided into pre-filtration, online filtration and post-filtration. Pre-filtration refers to the pre-treatment of lubricating oil through a filter before injecting it into the equipment. This filtration method is mainly to remove impurities and particles in the lubricating oil to prevent them from entering the equipment, thereby reducing equipment wear and failure. The filter used is usually a filter or a centrifugal structure. It can remove impurities and particles to a certain extent.

[0004] However, although lubricating oil itself is a liquid, due to its high viscosity, its fluidity is not as good as that of fluids such as water. Therefore, it flows very slowly during filtration, and the filtration process is very long. Utility Model Content

[0010] Further, the metal lower cover can be replaced with an elastic one. On this basis, the diameter of the elastic lower cover is slightly larger than the inner diameter of the heating barrel.

[0011] Further, a plurality of uniformly distributed fine holes are formed through the top cover, and these fine holes are used for the circulation of water vapor.

[0012] Further, the bottom end of the elastic lower cover is configured to form an outer rounded corner structure; at the same time, the top end of the heating barrel is configured to form an inner rounded corner structure, and the inner rounded corner structure corresponds to the outer rounded corner structure to reduce the resistance between the two when the elastic lower cover just contacts the heating barrel.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0020] The lubricating oil filtering device provided by this specific embodiment is as follows Figure 1 and Figure 2 shown, and includes an oil flow component and an auxiliary flow component, where:

[0021] The oil flow component includes an upper oil barrel 1. The bottom end of the upper oil barrel 1 is configured to form a filter screen 2 structure, and a lower oil barrel 3 is provided at its bottom end. The inner diameter of the lower oil barrel 3 is larger than that of the upper oil barrel 1. Specifically, the two oil barrels can be fixed by brackets. Any structure that can play a supporting role can be used, and no more details will be elaborated here.

[0022] The auxiliary flow component includes a spiral tube 4 wound around the outer wall of the upper oil barrel 1 from top to bottom; at the same time, it also includes a heating barrel 5 for heating water and located above the upper oil barrel 1. A communication mechanism 6 is provided between the heating barrel 5 and the spiral tube 4 so that hot water can circulate. As Figure 2 shown, the communication mechanism 6 includes a water pump 601. A first connecting pipe 602 is connected between the input end of the water pump 601 and the bottom end of the spiral tube 4. The output end of the water pump 601 is connected to a third connecting pipe 604. The end of the third connecting pipe 604 is connected to the heating barrel 5 near the top end of the heating barrel 5; in addition, a second connecting pipe 603 is connected between the top end of the spiral tube 4 and the bottom end of the heating barrel 5. In this way, under the action of gravity, the hot water in the heating barrel 5 flows into the spiral tube 4 through the second connecting pipe 603, heats the upper oil barrel 1 through the spiral tube 4, and then returns to the heating barrel 5 through the first connecting pipe 602, the water pump 601 and the third connecting pipe 604 to form a circulating heating structure, so that the lubricating oil can be heated during filtration to improve its fluidity.

[0023] In addition, as Figure 1 shown, a top cover 7 is provided at the top opening of the heating barrel 5. The top cover 7 is snap-connected to the opening of the heating barrel 5 so that the top cover 7 can be removed. Specifically, as Figure 3As shown, the top cover 7 is a metal cover, which includes an upper cover 701 and a lower cover 702. The diameter of the upper cover 701 is equal to the outer diameter of the heating barrel 5, and the diameter of the lower cover 702 is equal to the inner diameter of the heating barrel 5. Such a structural design can cover the opening during heating to avoid the leakage of hot air. However, the top cover 7 with such a structure is too heavy because it is made of metal, and it may be laborious to remove. Therefore, the metal lower cover 702 can be replaced with an elastic one. On this basis, in order to be able to engage, the diameter of the elastic lower cover 702 is preferably slightly larger than the inner diameter of the heating barrel 5, and the bottom end of the elastic lower cover 702 is constructed to form an outer rounded corner structure; at the same time, the top end of the heating barrel 5 is constructed to form an inner rounded corner structure, and the inner rounded corner structure corresponds to the outer rounded corner structure to reduce the resistance between the two when the elastic lower cover 702 just contacts the heating barrel 5. Moreover, because the weight is reduced, the top cover 7 may be pushed open by the hot air. Therefore, it is preferably that a plurality of uniformly distributed fine holes are formed through the top cover 7, and these fine holes are used for the outlet of water vapor.

[0024] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0025] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present application shall be covered within the protection scope of the present application.
