[0033] The oil separation disc 31 comprises an oil separation disc front plate 31-1 and an oil separation disc rear plate 31-2, the installation cavity is arranged on a side of the oil separation disc rear plate 31-2 close to the oil separation disc front plate 31-1, the oil separation disc front plate 31-1 is arranged in the installation cavity, and the oil absorption cotton 31-4 is arranged between the oil separation disc front plate 31-1 and the oil separation disc rear plate 31-2; a plurality of first water outlets 31-5 are arranged on the oil separation disc front plate 31-1 at equal intervals, a plurality of second water outlets 31-6 are arranged on the oil separation disc rear plate 31-2 at equal intervals, and the oil absorption disc handle 31-3 is arranged on the side wall of the oil separation disc rear plate 31-2.

[0034] The working process of the utility model is as follows:

[0035] Step 1. After the working grinding liquid enters the water tank through the water inlet 7, it first enters the sedimentation area 1, and the sedimentation area 1 is composed of multiple partitions, so that the water flow forms a flow state as shown in the figure. Figure 2 The flow state can make the fast flowing water flow further gentle, and some iron chips generated in processing can be deposited in this area; after the water flow passes through the sedimentation area 1 and enters the first magnetic attraction area;

[0036] Step 2. The first magnetic attraction area 2 is provided with a plurality of magnet frames. The machining iron filings that are not precipitated in the precipitation area 1 are mostly attracted by the magnet frames when passing through the first magnetic area 2. The number of iron filings on the magnet frame is very large. The magnet frame is designed to consider how to quickly clean the iron filings. The magnet frame includes a magnet assembly and an outer frame. The gap between the outer diameter of the magnetic rod 21-1 and the hole diameter of the stainless steel tube 23-3 is 2-8mm. Avoiding the gap being too large to cause insufficient magnetic force and reduce the effect. When the magnet assembly 21 is full of iron filings during work, the magnet assembly 21 is only taken out of the water tank and separated from the outer frame 23. The iron filings attached to the outer frame 23 can be quickly removed due to the lack of magnetism of the magnet assembly 21 and the non-magnetic characteristics of stainless steel. Then the magnet assembly 21 and the outer frame 23 are combined to work again.

[0037] Step 3. When the water flow passes through the first magnetic attraction area 2, it will enter the first oil separation area 3 provided with an oil separation disc 31. The first oil separation area 3 is mainly used to separate the oil substances attached to the surface of the processed parts during the previous process due to rust prevention. The oil substances will enter the water tank with the grinding liquid. In order to avoid too much oil substance changing the characteristics of the grinding liquid and reducing the efficiency of the grinding liquid, the oil separation disc 31 in the first oil separation area 3 is clamped with oil absorption cotton 31-4. The oil absorption cotton 31-4 has the characteristics of absorbing oil and not absorbing water, which can effectively isolate the oil substances in front of the oil absorption cotton 31-4. Then the oil substances are taken out regularly by using tools, thereby prolonging the service life of the grinding liquid.

[0038] Step 4. When the water flow passes through the first oil separation area 3, it will enter the second magnetic attraction area 4 and the second oil separation area 5. The grinding liquid is filtered again and then enters the clean water area 6. The self-priming pump is used to pump the filtered grinding liquid in the clean water area 6 into the equipment pipeline for use.

[0039] The multi-stage grinding liquid filtering water tank of the utility model precipitates impurities through the precipitation area, the first magnetic attraction area magnetically attracts iron, then the first oil separation area separates oil stains by layers, and finally enters the second magnetic attraction area and the second oil separation area for fine filtering. The oil stains and impurities in the grinding liquid can be effectively removed, thereby ensuring the quality of the grinding liquid and greatly prolonging the service life of the grinding liquid.

[0040] The magnetic rod in the magnet frame and the oil absorption cotton of the oil separation disc both have the characteristics of being reusable, which can reduce the cost of consumables. The whole cleaning is convenient, which reduces the labor cost of cleaning the water tank by workers, thereby greatly reducing the production cost and improving the overall competitiveness.

[0041] Finally, it should be explained that the above specific embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the examples, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the present application, and all should be covered in the scope of the claims of the present application.
