Description

Technical Field

[0001] The utility model relates to the field of mechanical equipment lubrication, in particular to a device for cyclone-type circulation purification of lubricating oil when the mechanical equipment is working. Background Art

[0002] Lubricating oil is the blood of mechanical equipment, especially in the application fields of bearings, gears, sprockets, etc. The quality of lubrication directly affects the life of the equipment. Due to the wear of transmission parts, tiny powders flow into the oil pool with the lubricating oil. Especially for equipment operating in harsh outdoor environments, dust will invade the transmission box from the respirator, oil seal and other parts, causing lubricating oil pollution. Traditional filtering equipment mainly includes filter filtration and magnetic adsorption. Both methods have a certain effect on keeping the lubricating oil clean, but each has its own disadvantages. When using filter filtration, as the equipment runs for an increasing amount of time, impurities will gradually block the pores of the filter, resulting in poor suction effect of the gear pump, discharge pressure fluctuations and unstable flow, so the filter should be disassembled regularly for replacement or cleaning; magnetic adsorption has a good adsorption effect on magnetic conductive material powder, but has no effect on copper, aluminum alloy, non-metallic materials, etc. Utility Model Content

[0003] In view of the above problems, the utility model provides a cyclone-type self-purification device for lubricating oil, which solves the drawbacks of the existing filtering equipment mentioned in the background technology.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a lubricating oil cyclone self-purification device, comprising a cyclone separator, a 90° pipe joint, a retaining hose and a gear oil pump connected in sequence, an oil inlet pipe is provided at the inlet end of the cyclone separator, the other end of the oil inlet pipe is connected to the equipment oil pool, a first ball valve is provided between the oil inlet pipe and the cyclone separator, a sewage collecting bucket is provided under the slag discharge port of the cyclone separator, and a sewage discharge pipe and a sewage discharge ball valve are provided at the lower end of the sewage collecting bucket.

[0005] As an optimization, a ferrule-type pipe joint is provided on the 90° pipe joint at one end close to the cyclone separator, and a C-type retaining pipe joint is provided on one end close to the retaining hose.

[0006] As an optimization, a square-round connecting pipe is provided between the first ball valve and the cyclone separator, and a direct joint is provided between the first ball valve and the square-round connecting pipe.

[0007] The beneficial effects of the utility model are as follows: the utility model provides a cyclone type self-purification device for lubricating oil, which adopts the centrifugal sedimentation principle and adds a cyclone type separator on the suction pipeline of the gear oil pump. The lubricating oil flows in from the upper part of the straight cylinder section of the cyclone type separator along the tangential direction and rotates and flows downward along its inner wall to form an external cyclone. Impurities with a density heavier than the lubricating oil flow along the inner wall under the action of centrifugal force and consume kinetic energy by friction with it, and finally fall into the dirt collecting barrel under the action of gravity and no longer participate in the circulation. The lubricating oil with a lighter density forms an internal cyclone in the conical section of the cyclone type separator and flows out from the top along the center. The impurities in the lubricating oil are separated by centrifugal force and gravity, and there are no wearing parts, which is easy to use and has low pressure loss. The device can be used alone, and can also be used in combination with a filter screen and magnetic adsorption in precision transmission occasions. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] like Figure 1-2 As shown, a cyclone type self-purification device for lubricating oil comprises a cyclone separator 4, a 90° pipe joint 3, a retaining hose 5 and a gear oil pump 6 which are connected in sequence, an oil inlet pipe is provided at the inlet end of the cyclone separator 4, the other end of the oil inlet pipe is connected to the equipment oil pool, a first ball valve 1 is provided between the oil inlet pipe and the cyclone separator 4, a sewage collecting bucket 7 is provided under the slag discharge port of the cyclone separator 4, and a sewage discharge pipe and a sewage discharge ball valve 8 are provided at the lower end of the sewage collecting bucket 7.

[0015] The 90° pipe joint 3 is provided with a ferrule-type pipe joint 10 at one end close to the cyclone separator 4, and is provided with a C-type retaining pipe joint 11 at one end close to the retaining hose 5; the oil inlet and outlet are connected by a ferrule-type connection, and there is no need to rotate the first ball valve 1 and the cyclone separator 4 during installation, so the space occupied is small, and the direction of the oil outlet can be rotated 360° along the axis, which is convenient for connecting pipelines in a small space.

[0016] The efficiency of centrifugal sedimentation pollution removal mainly depends on the size of the centrifugal force and the cross-sectional shape of the vortex entering the cyclone separator 4. A square-circular connecting pipe 2 is provided between the first ball valve 1 and the cyclone separator 4, and a direct joint 9 is provided between the first ball valve 1 and the square-circular connecting pipe 2. One end of the square-circular connecting pipe 2 is circular for convenient pipeline connection, and the other end is rectangular. By controlling the size of the rectangular end face, the lubricating oil can have an ideal inlet flow rate and cross-sectional shape, so that the device has a higher pollution removal efficiency.

[0017] Working principle: The utility model provides a cyclone type self-purification device for lubricating oil, which adopts the principle of centrifugal sedimentation and adds a cyclone separator 4 to the suction pipeline of the gear oil pump 6. The lubricating oil flows in from the upper part of the straight cylinder section of the cyclone separator 4 along the tangential direction and rotates downward along its inner wall to form an external cyclone. Impurities with a density heavier than the lubricating oil flow along the inner wall under the action of centrifugal force and consume kinetic energy by friction with it. Finally, they fall into the dirt collecting barrel 7 under the action of gravity and no longer participate in the circulation. The lubricating oil with a lighter density forms an internal cyclone in the conical section of the cyclone separator 4 and flows out from the top along the center. The impurities in the lubricating oil are separated by centrifugal force and gravity. There are no wearing parts, it is easy to use and has low pressure loss. The device can be used alone and can also be used in combination with a filter screen and magnetic adsorption in precision transmission occasions.
