[0002] Cutting fluid is an important auxiliary material used in the metal processing process. It plays a vital role in improving processing efficiency, ensuring processing quality, extending tool life and protecting processing equipment. The main functions of cutting fluid include: cleaning effect. Cutting fluid is responsible for removing fine metal chips generated during processing to prevent them from scratching the workpiece surface or clogging the tool, maintaining the cleanliness of the processing area, thereby reducing additional processing damage.

[0003] In the metal processing industry, in order to save resources and reduce production costs, the recycling of cutting fluid is a common practice, which requires an effective cutting fluid filter. However, in the operation of existing filter devices, regular manual inspections are required to monitor the accumulation of metal chips on the filter. Once the filter is blocked from flowing cutting fluid due to the accumulation of metal chips, the conventional practice is to suspend production operations and perform manual cleaning. This process is undoubtedly time-consuming and reduces overall production efficiency, adding additional manpower and time costs. Utility Model Content

DETAILED DESCRIPTION

[0027] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0028] like Figures 1 to 3 As shown, a cutting fluid filtering device of the utility model comprises:

[0029] A main body 1, in which a cavity 2 for storing cutting fluid is provided;

[0030] A water return member 3 is provided on the main body 1 and is located above the cavity 2. The water return member 3 is connected to the metal processing machine tool and is used for the cutting fluid and the metal chips carried by the cutting fluid to flow into the main body 1.

[0031] A filter assembly is arranged on the main body 1, and comprises a filter element 4 and a float 5 arranged above the filter element 4. The filter element 4 is located below the water return element 3. The cutting fluid flows into the cavity 2 through the filter element 4. The filter element 4 is preferably a filter cloth.

[0032] The pumping member 6 is disposed in the cavity 2 and is used to pump the filtered cutting fluid out of the cavity 2 and reuse it in the metal processing process. The pumping member 6 is preferably a pump.

[0033] Under working condition, the cutting fluid carrying metal chips is introduced into the main body 1 through the return water component 3. Under the action of the filter element 4, the cutting fluid is finely filtered and then enters the cavity 2 of the main body 1, while the metal chips are effectively retained on the surface of the filter element 4. As the metal chips on the filter element 4 gradually accumulate, the flow of the cutting fluid is blocked and the liquid level rises, causing the float 5 to float up, automatically triggering the filter component to respond, driving the blocked part of the filter element 4 and the metal chips accumulated thereon to move to a preset position. At the same time, the filtration process is uninterrupted, and the filtered cutting fluid is immediately pumped out by the pumping component 6 and reused in the metal processing process, realizing the effective circulation of resources. In this process, there is no need for manual continuous monitoring of the blockage of the filter element 4, nor is there any need to interrupt production due to cleaning the metal chips accumulated on the filter element 4, which significantly improves work efficiency and greatly reduces the cost of manual intervention.

[0034] More specifically, the filtering component also includes:

[0035] A support frame 7, which is threadedly connected to the main body 1 and is located above the cavity 2;

[0036] The conveyor belt 8 is arranged on the support frame 7, one end of the filter element 4 is movably wound on the support frame 7 and is located above the conveyor belt 8, and the other end of the filter element 4 is flatly laid on the surface of the conveyor belt 8 and is located below the water return element 3;

[0037] The driving member 9 is arranged at one side of the support frame 7 and is drivingly connected to the conveyor belt 8. The driving member 9 is preferably a motor.

[0038] When the float 5 is lifted up due to the rise in liquid level caused by the accumulation of metal chips above the filter element 4, the driving element 9 immediately responds to the vertical displacement change, and then activates and drives the conveyor belt 8 to rotate, thereby moving the filter element 4 on the conveyor belt 8 and the metal chips attached thereto to the specified position. At the same time, the part of the filter element 4 wound on the support frame 7 gradually unfolds and spreads on the surface of the conveyor belt 8 as the conveyor belt 8 rotates, and is immediately put into use to continue filtering the cutting fluid transported by the return water element 3. This process maximizes the use efficiency of the filter element 4 and reduces the frequency of manual intervention.

[0039] In order to effectively collect the clogged part of the filter element 4 and the metal chips attached thereto transported by the conveyor belt 8 , a collecting element 10 is further provided on the side of the main body 1 , and the conveyor belt 8 transports the clogged part of the filter element 4 and the metal chips accumulated thereon to the collecting element 10 .

[0040] In order to monitor the vertical displacement of the float 5 as the liquid level above the filter element 4 changes in real time, a detection element 11 is further provided on the main body 1, and the float 5 is movably connected below the detection element 11, and the detection element 11 is electrically connected to the drive element 9 to ensure the immediate and accurate transmission of the displacement signal. Once the float 5 rises due to the increase in liquid level caused by the accumulated metal chips on the filter element 4, the detection element 11 instantly senses this change and immediately transmits the detected displacement signal to the drive element 9, triggering the drive element 9 to initiate a corresponding operational response, thereby ensuring that the filter assembly can quickly and accurately adjust itself to maintain the efficient operation of the filtration process. The detection element 11 is preferably a displacement sensor.

[0041] In order to provide support for the water return member 3 and the detection member 11 , a support block 12 is threadedly connected to the support frame 7 , the water return member 3 is connected to the support block 12 , and the detection member 11 is connected to one side of the support block 12 .

[0042] In order to preliminarily filter the cutting fluid flowing out of the water return member 3, a filter tank 13 is also provided on the support block 12, which is located directly below the water return member 3. This design requires the cutting fluid and the metal chips entrained therein to be filtered by the filter tank 13 before flowing to the filter member 4 on the support frame 7, thereby improving the efficiency of the overall filtration system and the circulation quality of the cutting fluid.

[0043] In order to promote the effective precipitation of impurities in the cutting fluid flowing down from the filter element 4, a plurality of baffles 14 are arranged in the cavity 2, and the vertical height of each baffle 14 is lower than the overall height of the cavity 2, and the height between the baffles 14 can be that all baffles 14 maintain a uniform height to form a uniform liquid flow obstruction, or adopt a stepped distribution, that is, the heights of adjacent baffles 14 change in sequence to guide the multi-level flow of the cutting fluid and promote the precipitation of impurities. Another type is that the baffles 14 on both sides maintain a relatively high height, while the middle baffle 14 has the lowest height. Such a layout forms a groove shape to further optimize the precipitation effect. These differentiated layouts are all aimed at significantly enhancing the purification efficiency and recycling value of the cutting fluid by improving liquid flow guidance and establishing an effective precipitation area.

[0044] In order to lift the support frame 7 away from the main body 1, at least one handle 15 is provided on both sides of the support frame 7. When it is necessary to replace the cutting fluid in the cavity 2 or perform equipment maintenance, the staff can first loosen the threaded connection between the support frame 7 and the main body 1, and then easily lift the support frame 7 by holding the handle 15, so as to completely remove the support frame 7 for subsequent maintenance or replacement operations.
