Description

Technical Field

[0001] The utility model relates to the technical field of lubricating oil production, in particular to a filtering device for lubricating oil production. Background Art

[0002] Lubricating oil is a liquid or semi-solid lubricant used to reduce friction and protect machinery and processed parts. It is composed of two parts: base oil and additives. Base oil is the main component of lubricating oil and determines its basic properties. Additives are used to make up for and improve the deficiencies in the performance of base oil and impart certain new properties. The main functions of lubricating oil include lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering.

[0003] In the process of lubricating oil production, it is necessary to filter out the particulate impurities inside it. However, since the lubricating oil has a certain viscosity and poor fluidity, the filtering efficiency is low. For this reason, we propose a filtering device for lubricating oil production. Utility Model Content

[0004] The utility model aims to provide a filtering device for lubricating oil production, which has the advantages of being able to improve the filtering efficiency of lubricating oil in production and reduce production costs, and solves the problem that the current lubricating oil has a certain viscosity and poor fluidity, resulting in low filtering efficiency.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a filtering device for lubricating oil production, comprising a filter tank body, a rotating shaft is rotatably installed at the top axial position of the inner wall of the filter tank body, a rotating motor is fixedly installed at the axial position of the upper surface of the filter tank body, four fixed connecting rods are fixedly connected in a circular array at equal intervals on the outer surface of the rotating shaft near the lower surface, a connecting pipe is rotatably installed at the bottom axial position of the inner wall of the filter tank body, a conical bucket is fixedly connected to one end of the connecting pipe located inside the filter tank body, and the end of the fixed connecting rod is fixedly connected to the inner wall of the conical bucket, a filter cartridge is welded on the upper surface of the conical bucket, and a slag discharge valve is fixedly connected to one end of the connecting pipe located outside the filter tank body.

[0006] Preferably, the end of the output shaft of the rotating motor is fixedly connected to the upper surface of the rotating shaft, and the rotating motor drives the rotating shaft to rotate.

[0007] Preferably, an oil inlet pipe is fixedly connected to one side of the upper surface of the filter tank body, and an oil outlet pipe is fixedly connected to the lower surface of the filter tank body near the edge. The lubricating oil to be filtered enters the filter tank body from the oil inlet pipe, and the filtered and purified lubricating oil is discharged from the oil outlet pipe.

[0008] Preferably, a quick connector is fixedly connected to the end of the oil inlet pipe, and the oil supply pipeline of the lubricating oil to be filtered is quickly and fixedly connected to the oil inlet pipe through the quick connector.

[0009] Preferably, a plurality of rollers are equidistantly installed in a circular array on the inner wall of the filter tank body near the upper surface. When the filter cartridge rotates, the rollers contact the outer surface of the filter cartridge, limiting the filter cartridge, preventing the filter cartridge from swinging, and improving the stability and service life of the filter cartridge.

[0010] Preferably, a fixed box is fixedly installed on one side of the upper surface of the filter tank body, and an electric push rod and a brush plate are rotatably installed inside the fixed box, and the end of the electric push rod is rotatably connected to one end of the brush plate located inside the fixed box. A through opening is provided on the upper surface of the filter tank body at a position below the fixed box, and the brush plate passes through the through opening, and the end of the brush plate is located inside the filter cartridge. When it is necessary to clean the impurities adhering to the inner wall of the filter cartridge, the electric push rod drives the brush plate to rotate so that the brush plate contacts the inner wall of the filter cartridge. During the rotation of the filter cartridge, the brush plate brushes off the impurities adhering to the inner wall of the filter cartridge. After the impurities are removed, the electric push rod drives the brush plate to rotate in the opposite direction, so that the brush plate is separated from the inner wall of the filter cartridge, thereby avoiding large wear of the brush plate and extending the service life of the brush plate.

[0011] Preferably, four supporting legs are fixedly installed in a circular array at equal intervals on the lower surface of the filter tank body near the edge, and the four supporting legs play a role of fixed support for the filter tank body.

[0012] Preferably, a first fixed baffle ring is welded to the bottom of the inner wall of the filter tank body, and an annular groove that can accommodate the filtered lubricating oil is formed between the first fixed baffle ring, the bottom of the filter tank body and the side wall of the filter tank body, thereby facilitating the filtered lubricating oil to be discharged from the oil outlet pipe, while also blocking the lubricating oil from flowing to the junction between the connecting pipe and the filter tank body, and preventing the lubricating oil from flowing out from the junction.

[0013] Preferably, a second fixed baffle ring is welded on the lower surface of the conical bucket to prevent the filtered lubricating oil from flowing along the outer surface of the conical bucket, so as to avoid the lubricating oil from flowing to the junction of the connecting pipe and the filter tank body and flowing out from the junction gap.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model achieves the effect of improving the filtering efficiency of lubricating oil in production and reducing production costs by arranging a filter tank body, a conical bucket, a slag discharge valve, a filter cartridge, a rotating motor and a rotating shaft. The lubricating oil enters the inside of the filter cartridge, and the rotating motor drives the rotating shaft and the filter cartridge to rotate. Then, under the action of centrifugal force, the lubricating oil passes through the filter cartridge, while impurities are left inside the filter cartridge and fall into the conical bucket. The impurities are discharged through the slag discharge valve, which can greatly improve the filtering efficiency of the lubricating oil.

[0016] 2. The utility model achieves the effect of improving the stability of the filter cartridge during rotation by arranging a roller. When the filter cartridge rotates, the roller contacts the outer surface of the filter cartridge, limits the filter cartridge, prevents the filter cartridge from swinging, and improves the stability and service life of the filter cartridge.

[0017] 3. The utility model achieves the effect of facilitating the removal of impurities adhered to the inner wall of the filter cartridge by arranging a fixed box, a brush plate and an electric push rod. When it is necessary to clean the impurities adhered to the inner wall of the filter cartridge, the electric push rod drives the brush plate to rotate so that the brush plate contacts the inner wall of the filter cartridge. During the rotation of the filter cartridge, the brush plate brushes off the impurities adhered to the inner wall of the filter cartridge. After the impurities are removed, the electric push rod drives the brush plate to rotate in the opposite direction so that the brush plate is separated from the inner wall of the filter cartridge, thereby avoiding greater wear of the brush plate and extending the service life of the brush plate.

[0018] 4. The utility model achieves the effect of preventing the lubricating oil from flowing out from the gap between the connecting pipe and the filter tank body by setting the first fixed baffle ring, and also facilitates the discharge of the filtered lubricating oil. An annular groove that can accommodate the filtered lubricating oil is formed between the first fixed baffle ring, the bottom of the filter tank body and the side wall of the filter tank body, which is conducive to the discharge of the filtered lubricating oil from the oil outlet pipe, and also blocks the lubricating oil from flowing to the junction of the connecting pipe and the filter tank body.

[0019] 5. The utility model prevents the filtered lubricating oil from flowing along the outer surface of the conical bucket by setting a second fixed baffle ring, so as to prevent the lubricating oil from flowing to the junction of the connecting pipe and the filter tank body and flowing out from the junction gap.
