Description

Technical Field

[0001] The utility model relates to the technical field of machine tool oil mist fans, in particular to a machine tool oil mist fan. Background Art

[0002] The machine tool oil mist machine is a device specially used to collect and remove the oil mist and dust generated during the machining process of the machine tool. The machine tool oil mist machine is generally composed of an air suction port, a filter, a fan, an electric control box, etc. Among them, the air suction port is used to collect the oil mist, the filter is used to filter the dust in the oil mist, the fan is used to enhance the suction force, and the electric control box is used to control the operation of the machine. When selecting, attention should be paid to the diameter and length of the air suction port, as well as the material and filtration efficiency of the filter. The appropriate oil mist machine should be selected according to the size of the machine tool and the amount of oil mist generated, and the installation position needs to be easy to disassemble and clean. The machine tool oil mist machine can effectively remove the oil mist and dust generated during the machining process of the machine tool, improve the machining quality and product precision. During the production process, the industrial oil mist has a high temperature, and the oil mist is easily fissioned into toxic and harmful substances and odors such as acrolein, benzopyrene and cyclic aromatic hydrocarbons, which directly cause mutagenic, teratogenic and carcinogenic effects on production personnel. The oil mist itself also has adverse effects on the health of workers in the workshop. Leading to some respiratory diseases such as pneumonia, bronchitis, asthma and contact dermatitis, the oil mist in the workshop will harm the cutting tool and reduce its service life. The mist diffuses in the air and will cause machine tool circuit system and control system failure for a long time. The oil mist is directly discharged in the air-conditioned workshop, which will damage the filter in the air-conditioning system of the machining workshop, reduce the air-conditioning energy efficiency and service life, and increase the air-conditioning operation cost. Therefore, adding a machine tool oil mist machine can reduce the pollution to the machine tool and the surrounding environment and reduce the health risks of operators, and reduce the occurrence of occupational diseases. The machine tool oil mist machine is suitable for various machine tools, such as milling machines, grinders, lathes, drilling machines, etc., but the traditional machine tool oil mist machine will increase the overall height of the machine tool during installation. At the same time, the purchase cost of the installed machine tool oil mist machine is high, which is not conducive to the installation and modification of old machine tools. The oil mist collected by the machine tool oil mist machine can only be stored inside the oil mist machine waiting for cleaning and cannot be recycled. Utility Model Content

[0030] Embodiment 1

[0031] The present embodiment discloses: a mounting housing 1, an upper cover 2 is slidably mounted on the upper end of the mounting housing 1, an air inlet 3 is opened on the lower surface of one end of the mounting housing 1, an electric fan 4 is fixedly mounted inside the mounting housing 1, and a protective cover 5 is fixedly mounted on the side of the electric fan 4 facing the air inlet 3, and an oil filter mechanism is arranged inside the mounting housing 1, which condenses and refluxes the oil mist by filtering the oil mist;

[0032] The oil filter mechanism comprises: a plug-in slot 6, the plug-in slot 6 is provided on the inner surface of the mounting shell 1, and an easily detachable mounting plate 7 is mounted on the temporal part of the plug-in slot 6, a hollow filter plate 8 is arranged inside the easily detachable mounting plate 7, and a limiting paddle 9 is fixedly arranged on the outer surface of one side of the easily detachable mounting plate 7, an impurity filter screen 10 is mounted between two limiting paddles 9, a clearance slot 11 is provided at the lower end of the easily detachable mounting plate 7, a closing block 12 is fixedly arranged on the inner bottom surface of the mounting shell 1, and an oil return port 13 is provided on the lower surface of one end of the mounting shell 1;

[0033] The easily removable mounting plate 7 is designed to be oblique, and holes are evenly opened on the surface of the hollow filter plate 8, and the holes on the surfaces of adjacent hollow filter plates 8 are staggered, and gaps are left between adjacent hollow filter plates 8;

[0034] The impurity filter screen 10 is of conical design, and the diameter of the holes on the surface of the impurity filter screen 10 is larger than the diameter of the holes on the surface of the hollow filter plate 8, and the clearance groove 11 is engaged with the closing block 12 for installation;

[0035] During normal operation, the electric fan 4 is started and the protective cover 5 is used to protect the electric fan 4 to extend the service life of the electric fan 4. At this time, the electric fan 4 drives the gas to flow into the mounting shell 1 from the air inlet 3, and the gas containing oil mist passes through the impurity filter 10 installed by the limit paddle 9 on the side surface of the easily detachable mounting plate 7 to initially filter out some impurities. At this time, the oil mist enters between the hollow filter plates 8 with the air and adheres to the surface of the hollow filter plates 8 through the collision with the surface of the hollow filter plates 8. When cleaning is needed, the upper cover 2 is slid up to expose the easily detachable mounting plate 7 installed in the plug-in slot 6, and the easily detachable mounting plate 7 is moved up to disengage the make way slot 11 from the engagement with the closing block 12. At this time, the oil mist condensed between the hollow filter plates 8 flows out to the interior of the mounting shell 1 through the make way slot 11 and is discharged through the oil return port 13 to wait for recycling.

[0036] Embodiment 2

[0037] This embodiment is based on the embodiment 1 and discloses that the oil filter mechanism further includes: a closed flap 14, which is rotatably mounted on the inner surface of the air inlet 3, and a functional groove 15 is provided on the outer surface of the closed flap 14 facing the impurity filter 10, and a sliding contact block 16 is installed on the inner bottom surface of the mounting housing 1 between the air inlet 3 and the impurity filter 10, and one end of the contact block 16 is fixedly connected to a squeezing block 17;

[0038] A spring is connected between the contact block 16 and the mounting housing 1, and the contact block 16 is designed as a right-angle trapezoid, and the inclined surface of the contact block 16 is arranged upward toward the functional slot 15 at one end of the closed flap 14;

[0039] The extrusion block 17 is designed as a right-angle trapezoid, and the inclined surface of the extrusion block 17 is upwardly disposed toward the limiting paddle 9 below;

[0040] When the electric fan 4 is started, the closed flap 14 flips up under the blowing of the airflow to ensure gas circulation. After the electric fan 4 is turned off, the closed flap 14 squeezes the inclined surface of the contact block 16 through the functional slot 15 during the downward flipping process. The contact block 16 slides through the inclined surface of the squeezing block 17 to squeeze the limiting paddle 9, so that the limiting paddle 9 drives the easily detachable mounting plate 7 to move up as a whole and drives the upper cover 2 to slide up. At this time, the giving way slot 11 is disengaged from the closing block 12. At this time, the oil mist condensed between the hollow filter plates 8 flows out through the giving way slot 11 to the interior of the mounting housing 1 and is discharged through the oil return port 13 to wait for recycling.
