An iron fillings filter equipment and gear production line of this application embodiment are described below with reference to the drawings.

Referring to fig. 1, the iron filings filtering device may include a placing box 1, a filter net 2, a magnetic separation box 3, a first filtering box 4 and a second filtering box 5.

Place 1 upper shed indent of box and set up for the storage iron fillings is provided with the less filter screen in aperture 2 at the lower surface of placing 1 of box, places 1 of box and filter screen cooperation, makes iron fillings pile up placing 1 of box, and the oil then passes the filter screen.

In figure 1, the magnetic separation box 3, the filter screen 2 and the placing box 1 are shown in an explosion view.

It can be understood that the magnetic separation box 3 is concave and the upper opening is arranged, and the cross-sectional areas of the filter screen 2 and the lower horizontal plane of the placing box 1 are smaller than the area of the upper opening of the magnetic separation box 3, so that the filter screen 2 and the placing box 1 can be placed into the magnetic separation box 3.

Specifically, the two opposite sides of the placing box 1 are provided with convex handheld portions, and the handheld portions extend out of the wall surface of the magnetic separation box 3, so that the placing box 1 is placed at the opening of the magnetic separation box 3 and does not fall down. And the hand-held part also facilitates the taking out of the placing box 1 so as to clear the accumulated iron filings.

As shown in fig. 2, a plurality of groups of permanent magnets 31 are provided on the inner wall of the magnetic separation box 3. Each group of permanent magnets 31 is arranged in a flat plate shape, and each group of permanent magnets 31 is arranged in parallel.

Specifically, the flat permanent magnet 31 and the inner wall of three sides of the magnetic separation box 3 are fixedly connected, and the permanent magnet 31 and the side wall of the other side of the magnetic separation box 3 are not connected, so that a gap is formed between the permanent magnet 31 and the magnetic separation box 31, and oil can flow.

Further, a gap formed by the first permanent magnet 31 and the magnetic separation box 31 is located on the left side of the magnetic separation box 3, a gap formed by the second permanent magnet 31 and the magnetic separation box 31 is located on the right side of the magnetic separation box 3, and a gap formed by the third permanent magnet 31 and the magnetic separation box 31 is located on the left side of the magnetic separation box 3. By analogy, the gaps formed by the odd permanent magnets 31 and the magnetic separation boxes 31 are positioned on the left side of the magnetic separation box 3, and the gaps formed by the even permanent magnets 31 and the magnetic separation boxes 31 are positioned on the right side of the magnetic separation box 3 to form a bow-shaped flow channel, so that oil materials can be in full contact with the permanent magnets 31, and the effect of fully removing iron is achieved.

It can be understood that the gaps formed between the two adjacent permanent magnets 31 and the magnetic separation box are not on the same side any more, i.e. a "bow" shaped flow channel can be formed.

Further, the permanent magnet 31 includes a flat surface portion and a slope surface portion. Wherein the plane part is fixedly connected with the wall surface of the magnetic separation box 3 at one side opposite to the gap, and the inclined plane part extends to the gap from the plane part. The inclined plane part arranged on the permanent magnet 31 prevents oil from being accumulated in the magnetic separation box 3.

The lower part of the magnetic separation box 3 is communicated with the upper part of the first filter box 4, and oil with iron removed by the magnetic separation box 3 flows into the first filter box 4 through a pipeline. The bottom of the first filter box 4 is obliquely arranged, specifically, the bottom of the first filter box 4 is higher left and lower right, so that oil can be completely discharged out of the first filter box.

Furthermore, a plurality of groups of filter papers are arranged in the first filter box 4, the groups of filter papers are arranged in parallel, and a certain gap is arranged between two adjacent groups of filter papers.

The wall surface of the first filter cassette 4 can be opened so that the filter paper can be replaced. Moreover, the openable wall surface ensures the sealing of the entire first filter cassette 4 when closed, so that the first filter cassette 4 does not leak when in operation.

A second filter box 5 is arranged beside the discharge hole of the first filter box 4. The first filter box 4 and the second filter box 5 are connected through a pipeline, and oil in the first filter box 4 is loaded from the lower part of the second filter box 5, so that the iron removal effect is better.

In order to enable the oil to enter the lower part of the second filter box 5 from the lower part of the first filter box 4 to complete feeding, an oil pump 6 is arranged between the first filter box 4 and the second filter box 5, and the oil pump 6 enables the oil to be fed from the lower part of the second filter box 5 and then discharged from the upper part of the second filter box 5.

Specifically, be provided with grease filtration membrane in second filter cartridge 5 for less oil molecule can pass through, and great iron fillings granule is blockked unable passing through filter membrane. The grease filtering membrane is also replaceable so that the second filtering cassette 5 can maintain a good filtering effect.

As shown in FIG. 3, a gear production line comprises a machine tool 7 and a scrap iron filtering device. The export of 7 discharge iron fillings of lathe is located and places box 1 directly over, and the output and the lathe intercommunication of second filter cartridge 5 further make the oil recycle that the deironing was accomplished. Meanwhile, the scrap iron content of the recovered oil is very low, so that the service life of the grinding wheel is greatly prolonged.

It should be understood that equivalents and modifications may be made by those skilled in the art based on the technical solution of the present invention and the inventive concept thereof, and all such modifications and alterations should fall within the scope of the present invention.
