Description

Technical Field

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

[0002] Waste lubricating oil, also commonly known as discarded lubricating oil, mainly comes from used lubricating oil replaced during the use of various machinery, vehicles, ships, etc. Waste oil is mixed with impurities such as water, dust, other miscellaneous oils and metal powder produced by wear of machine parts during use, causing the color to turn black and the viscosity to increase. Lubricating oil is mainly composed of base oil and additives, which contain a large number of toxic and harmful substances, such as heavy metals and volatile organic compounds. If waste oil is not handled properly, it will pose a potential threat to the environment and human health. For example, the random dumping of waste oil may cause soil and water pollution, resulting in barren land and turbid water sources, thus affecting the surrounding ecology and people's quality of life. Among them, waste lubricating oil will be reused after being filtered by a filtering device.

[0003] For example, the Chinese patent "A waste lubricating oil recycling storage primary filtration device" with announcement number CN209049115U includes a box body, a fixed plate is provided on one side of the box body, a motor is provided on the fixed plate, the motor is connected to one end of the rotating shaft through a coupling, the rotating shaft is mounted on the box body, and a support rod is provided on the outer wall of the rotating shaft, the other end of the support rod is connected to the inner wall of the filter barrel, and a bracket is provided at the other end of the box body. The outer part of the filter barrel is a prism shape, and filter holes are evenly opened on the filter barrel. A magnetic suction net is attached to the inner wall of the filter barrel, and a plurality of liquid-blocking rings are also provided on the inner wall of the filter barrel. The ground inside the box body is inclined, and the height near the motor end is less than the height far from the motor end, and an electromagnetic valve is provided on one side of the lower end of the box body.

[0004] Although the above-mentioned prior art can filter lubricating oil waste, in actual use, on the one hand, the filtering effect of lubricating oil waste is not good enough. When filtering, iron filings and larger solid particles in the lubricating oil waste are filtered and then recovered, resulting in the recovered lubricating oil waste containing pigments and other harmful substances, thereby reducing the filtering effect of the lubricating oil waste. On the other hand, the fluidity of lubricating oil waste is poor. When filtering lubricating oil waste, the lubricating oil waste is directly poured into the filtering device, resulting in the sticky lubricating oil waste sticking to the filtering device, thereby reducing the filtering rate of the lubricating oil waste. Therefore, it does not meet the existing needs. In this regard, we propose a filtering device for recycling lubricating oil waste. Utility Model Content

[0005] The utility model aims to provide a filtering device for recycling waste lubricating oil, so as to solve the problems of poor filtering effect of waste lubricating oil and poor fluidity of waste lubricating oil proposed in the above background technology.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: a filtering device for recycling waste lubricating oil, comprising a bracket, and four brackets are provided, the upper end of the bracket is fixedly provided with a base, the upper end of the base is fixedly provided with a filter tank, the upper end of the filter tank is provided with a tank cover, and the tank cover is connected to the filter tank by threads; and also includes:

[0007] A filter tube is arranged at the lower end of the tank cover, and the filter tube is fixedly connected to the tank cover, and a first filter screen is fixedly arranged inside the lower end of the filter tube;

[0008] A mounting plate is arranged inside the filter tank below the filter tube, graphite filling powder is arranged at the middle position inside the mounting plate, and a second filter screen is fixedly arranged at the upper and lower ends of the graphite filling powder inside the mounting plate, and the mesh aperture of the second filter screen is smaller than the mesh aperture of the first filter screen.

[0009] Preferably, a heating chamber is provided inside the side wall of the filter tube, and the heating chamber is distributed in a spiral ascending manner.

[0010] Preferably, a heating wire is provided inside the heating chamber, and the heating wire is fixedly connected to the inner wall of the heating chamber.

[0011] Preferably, four positioning grooves are arranged inside the side wall of the filter tank, and the positioning grooves are equidistantly distributed in a circular shape. Four limiting rods are arranged outside the mounting plate, and the limiting rods correspond to the positions of the positioning grooves, and one end of the limiting rods extends to the inside of the positioning grooves.

[0012] Preferably, four fixing rods are fixedly provided on the upper end of the mounting plate close to the outer side of the second filter screen, and the fixing rods are equidistantly distributed in a ring shape.

[0013] Preferably, a magnetic rod is fixedly provided at the upper end of the first filter screen located inside the filter tube.

[0014] Preferably, a feed pipe is fixedly provided at the upper end of the tank cover, and the feed pipe is connected to the filter tube, a discharge pipe is fixedly provided at the lower end of the base, and the discharge pipe is connected to the filter tank, and a valve is fixedly provided on the outside of the discharge pipe.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model can filter other types of impurities in waste lubricating oil through graphite filling powder and the second filter. When filtering, the waste lubricating oil is first poured into the filter tank through the feed pipe. At this time, the waste lubricating oil first enters the filter tube, and the magnetic rod and the first filter screen will perform initial filtration on the waste lubricating oil. The magnetic rod absorbs metal impurities in the waste lubricating oil, and the first filter screen filters larger solid particles in the waste lubricating oil. At this time, the filtered waste lubricating oil falls onto the mounting plate, and the waste lubricating oil is filtered again through the second filter screen and the graphite filling powder. The second filter screen filters the fine fixed particles in the waste lubricating oil, and the graphite filling powder absorbs and filters the pigments and other harmful substances in the waste lubricating oil, thereby improving the filtering effect of the filtering device.

[0017] 2. The utility model can heat the waste lubricating oil in the filter tube through the heating wire and the heating chamber. When the waste lubricating oil is in the filter tube, the heating wire is energized. When the current passes through the heating wire, due to the resistance of the metal itself, the current will collide with the atoms in the metal body to generate heat, thereby causing the heating wire to generate heat, and the heat is transferred to the waste lubricating oil through the filter tube. At this time, the temperature of the waste lubricating oil increases, which improves the fluidity of the waste lubricating oil, so that the waste lubricating oil can pass through the first filter screen and the second filter screen more easily, thereby improving the filtration rate of the waste lubricating oil.

[0018] 3. The utility model can quickly disassemble and assemble the filter mechanism through the positioning groove and the mounting plate. After the lubricating oil and waste oil are filtered, the tank cover is opened to remove the tank cover together with the filter tube from the filter tank. At this time, the fixing rod is pulled upward to make the fixing rod drive the mounting plate to move upward until the mounting plate is detached from the filter tank. At this time, the operator cleans the impurities on the filter tube and the mounting plate, and then aligns the limit rod on the cleaned mounting plate with the positioning groove and pushes it into the positioning groove until the limit rod falls to the upper end surface inside the positioning groove, and then aligns the tank cover with the opening of the filter tank and places it on the upper end of the filter tank, and rotates the tank cover to fix the tank cover on the upper end of the filter tank. The filter mechanism can be quickly disassembled and assembled and cleaned, thereby reducing the use cost of the filtering device. BRIEF DESCRIPTION OF THE DRAWINGS
