[0002] During machining, water-based or oil-based cutting fluids are used extensively for cooling, lubrication, cleaning, and rust prevention. After being circulated by a pump, the cutting fluid collides violently with the cutting tool and workpiece, generating a large amount of oil mist particles through atomization and evaporation. Since oil mist can cause many hazards to industrial production and workers' health, it is necessary to purify the oil mist.

[0020] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example

[0022] Please see Figure 1-5 An EC fan filter element vacuum solid-liquid separation oil mist purification device includes an EC fan body 1, a first annular plate 2 is provided inside the EC fan body 1, a connecting plate 3 is provided on the outside of the first annular plate 2, the connecting plate 3 is connected to the rear inner wall of the EC fan body 1, a first filter layer 4 is provided on the front side of the first annular plate 2, a second filter layer 5 is sleeved on the outside of the first filter layer 4, and a third filter layer 6 is sleeved on the outside of the second filter layer 5.

[0023] The first filter layer 4, the second filter layer 5 and the third filter layer 6 are provided with a second annular plate 7. An opening is provided on the lower side of the EC fan body 1. A collection box 8 corresponding to the opening is provided on the lower side of the EC fan body 1. An outlet 9 is provided on the lower side of the collection box 8. Movable components are provided on both sides of the second annular plate 7.

[0024] The movable component includes a fixed piece 10 disposed on the front side of the second annular piece 7, and vertical rods 11 are slidably connected to the inner sides of both sides of the fixed piece 10;

[0025] It should be noted that in this technical solution, the first annular plate 2, the second annular plate 7, the first filter layer 4, the second filter layer 5, and the third filter layer 6 constitute a whole. Before use, the operator can remove the end cover on the front side of the EC fan body 1 and fix the first annular plate 2 inside the EC fan body 1 by screws and connecting plate 3. At the same time, the inner diameters of the first annular plate 2, the second annular plate 7, the first filter layer 4, the second filter layer 5, and the third filter layer 6 are all larger than the diameter of the impeller inside the EC fan body 1, and the distance between the first filter layer 4 and the impeller of the EC fan body 1 is ≥10mm. Therefore, when the EC fan body 1 is running, there will be no interference between the impeller and the above components, which can ensure the normal operation of the EC fan body 1.

[0026] The first filter layer 4 is made of stainless steel mesh to intercept oil mist particles with a diameter >5μm and protect the subsequent filter layers. The second filter layer 5 is made of polyester fiber to capture oil droplets with a diameter of 1-5μm and reduce the oil mist concentration. The third filter layer 6 is made of electrospun fiber, which can capture aerosol particles with a diameter <1μm to further purify the gas and ensure that the emissions meet the standards. At the same time, a notch 12 is provided on the lower side of the first annular plate 2, so that the oil mist particles intercepted by the first filter layer 4, the second filter layer 5 and the third filter layer 6 can flow out through the notch 12 and enter the collection box 8 through the opening for collection, which is convenient for operators to handle later.

[0027] Meanwhile, the surfaces of the first filter layer 4, the second filter layer 5, and the third filter layer 6 can all be coated with a Teflon oleophobic coating to prevent oil mist adhesion and increase the service life of the filter layers. Because this technical solution adds multiple filter layers inside the EC fan body 1, the overall size of the device is small and the use is flexible.

[0028] Furthermore, the surface of the second annular plate 7 is provided with threaded holes. After the filter layer is installed inside the EC fan body 1, the second annular plate 7 can be connected to the end cover of the EC fan body 1 by using the threaded holes and screws. This allows multiple filter layers to be connected to the EC fan body 1 as one unit, thereby preventing multiple filter layers from vibrating additionally when the EC fan body 1 is running, and ensuring the normal operation of the EC fan body 1.

[0029] After use, the front end cover of the EC fan body 1 can be removed, and the connecting piece 3 can be separated from the inner wall of the EC fan body 1. Then, the second annular piece 7, the first annular piece 2 and multiple filter layers can be taken out by using the fixing piece 10 and the vertical rod 11, and the filter layers can be maintained.

[0030] The surfaces of the first filter layer 4, the second filter layer 5, and the third filter layer 6 are all bent to increase the area of ​​the filter layers and thus enhance the oil mist interception effect.

[0031] A transparent observation port 13 is provided on the front side of the collection tank 8 to facilitate observation of the oil level inside the collection tank 8, and the control valve 14 can be opened to discharge the collected oil.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
