Description

Technical Field

[0001] The invention relates to the technical field of oil filters, in particular to a bubble absorption and oil return device for a lubricating oil filter. Background Art

[0002] At present, the known vacuum oil filter has an oil inlet nozzle, a liquid level controller and a window mirror observation hole installed in its vacuum tank and is connected to an oil drain pump and a condenser. When the oil inlet flow rate increases, the oil inlet nozzle in the vacuum tank also accelerates the spraying. Due to gravity and acceleration, a large amount of oil foam will be instantly generated when the oil hits the tank wall and the oil at the bottom of the tank. Since the power of the oil drain pump is constant, the oil discharge speed cannot be increased. At this time, the vacuum suction in the vacuum tank will quickly suck the oil foam to the top of the vacuum tank, causing the oil foam to flow to the condenser, resulting in reverse oil leakage. The machine is forced to stop and process the oil in the condenser before restarting, thereby greatly reducing the safe operation performance and production efficiency of the vacuum oil filter. This is a common phenomenon in vacuum oil filters at present.

[0003] In the related art, an oil baffle mechanism is provided inside the vacuum tank to prevent the oil that is about to enter the vacuum tank from directly contacting the oil inside the vacuum tank. Although this can achieve a good anti-foaming effect, in actual use, a large number of structures will be provided inside the vacuum tank, which will affect the normal use of the vacuum tank, has certain limitations, and is inconvenient to use.

[0029] In the vacuum tank of the vacuum oil filter, due to gravity and acceleration, a large amount of oil foam will be instantly generated when the oil hits the tank wall and the bottom of the tank. Because the power of the oil discharge pump is constant, the oil discharge speed cannot be increased. The oil bubbles are sucked to the top of the vacuum tank, causing the oil to flow to the condenser, resulting in reverse oil leakage, which greatly reduces the safe operation performance and production efficiency of the oil filter.

[0030] In the related art, an oil baffle mechanism is provided inside the vacuum tank to prevent the oil that is about to enter the vacuum tank from directly contacting the oil inside the vacuum tank. Although this can achieve a good anti-foaming effect, in actual use, a large number of structures will be provided inside the vacuum tank, which will affect the normal use of the vacuum tank, has certain limitations, and is inconvenient to use.

[0031] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a lubricating oil filter machine bubble absorption and oil return device. When it is needed, it is only necessary to install the pipe five 22 and the telescopic tube 23 inside the tank body 11, so that the oil passes through the pipe four 21, the pipe five 22, the telescopic tube 23 and the pipe six 24 in sequence, and enters the bottom surface of the tank body 11. When the oil level rises, the height of the pipe six 24 is automatically adjusted, so that the oil can flow smoothly into the tank body 11, thereby preventing the generation of foam. It is more convenient and quick, and the convenience of the device is improved.

[0032] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0033] Combination Figure 1-Figure 2The embodiment of the present application provides a lubricating oil filter machine bubble return oil device, including a main body component 1; the main body component 1 includes: a tank body 11, the top of which is fixedly connected to a pipe 12; a pipe 2 13, which is arranged at the top of the telescopic tank body 11, and one end of the pipe 2 13 is connected to a condenser; a pipe 3 14, which is arranged at the bottom of the tank body 11, and one end of the pipe 3 14 is connected to the oil inlet of the oil discharge pump; a telescopic component 2 is arranged on the tank body 11; the telescopic component 2 includes: a pipe 4 21, fixedly connected to the top of the tank body 11; pipeline five 22, fixedly connected to the top of the pipeline four 21, and one end of the pipeline five 22 is connected to the oil delivery structure; the telescopic tube 23, arranged at one end of the pipeline four 21; the pipeline six 24, fixedly connected to the bottom end of the telescopic tube 23; the floating plate 25, fixedly connected to the outside of the pipeline six 24; the floating ball 26, arranged on the outside of the floating plate 25, the telescopic tube 23 and the pipeline six 24 are both inclined, and the floating plate 25 is horizontally arranged.

[0034] When in use, after placing the tank body 11 at the designated position, the oil is transported to the pipe four 21 through the pipe five 22, and then the oil passes through the telescopic tube 23 and the pipe six 24 in turn and enters the tank body 11. Then, when the oil level rises, the float 26 and the floating plate 25 drive the pipe six 24 to rise upward, and then the telescopic tube 23 automatically contracts to keep the float 26 and the floating plate 25 parallel to the oil level.

Then, the oil is extracted through the pipe three 14 by the oil pump, and the steam generated during the treatment process enters the condenser through the pipe two 13, and the liquid in the steam is recovered.

[0035] Specifically, the floating plate 25 and the floating ball 26 are hollow floating plates and hollow floating balls.

[0036] In some embodiments, the pipe six 24 is a V-shaped pipe body, allowing the oil to flow smoothly into the tank body 11.

[0037] In some embodiments, there are multiple floats 26, which are arranged in a circular array around the center of the floating plate 25 to ensure that the bottom end of the pipeline 6 24 is always higher than the oil level.

[0039] When in use, the fixing bolt 34 is rotated to disengage one end of the tank body 11, and then the cover plate 33 is rotated to expose the second tank body 32 and the first tank body 31, so that the inside of the tank body 11 can be easily accessed. Conversely, after the cover plate 33 is fitted with the second tank body 32, the fixing bolt 34 is rotated to insert one end of the fixing bolt 34 into the tank body 11 to fix it.

[0040] In some embodiments, the rotating components 3 are provided in multiple groups, and the multiple groups of rotating components 3 can be used simultaneously or individually.

[0041] In some embodiments, a sealing gasket is provided on the cover plate 33 to improve the sealing effect.

[0043] When in use, after opening the cover plate 33, the screw 42 is rotated to separate it from the pipe seven 41, and then the pipe seven 41 is pulled to drive the telescopic tube 23 and the pipe six 24 to slide out of the tank body 11 to achieve disassembly, and vice versa to achieve installation.

[0044] In some embodiments, the top of the slot 31 is higher than the top of the screw 42 to facilitate the rotation of the screw 42.
