Description

Technical Field

[0001] This utility model relates to the field of grinding machine cutting fluid treatment technology, specifically a grinding machine cutting fluid treatment device for mold steel processing. Background Technology

[0002] When mold steel is processed by a grinding machine, cutting fluid needs to be continuously sprayed onto the contact area between the grinding wheel and the mold steel. After use, the cutting fluid will contain a large amount of metal debris. The presence of these metal debris will greatly affect the effectiveness of the cutting fluid. Therefore, a cutting fluid treatment device is needed to treat the cutting fluid containing metal debris.

[0003] As disclosed in CN215700869U, a cutting fluid treatment device for grinding machines used in mold steel processing includes a side plate; a partition plate; two rotating plates, one on each side of the partition plate; two filter screens fixedly connected to the two rotating plates, located on one side of the rotating plate and perpendicular to it; and a top plate positioned between the two partition plates, with a diversion channel controlling the flow of cutting fluid towards the two filter screens. The advantages of this invention are: it only requires controlling the two filter screens to periodically alternate between filtering and cleaning, eliminating the need for frequent manual cleaning of the filter screens, making operation more convenient and efficient.

[0004] Although the aforementioned patent has a jet pipe for cleaning the filter screen, before the filter screen is flipped over, the nozzle of the jet pipe faces the side of the top plate near the distribution chamber. As a result, debris in the cutting fluid may block the nozzle of the jet pipe as the cutting fluid flows. Although the one-way valve can prevent reverse flow, it cannot prevent solid particles from depositing. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-4 As shown, this utility model provides a technical solution:

[0025] A cutting fluid treatment device for grinding machines used in mold steel processing includes a circular treatment box 1. Vertical supports 15 are fixedly connected to the outside of both sides of the circular treatment box 1. A cover plate 2 is fixedly installed on the front of the circular treatment box 1. A guide column 3 is fixedly installed in the middle of the inner side of the circular treatment box 1. A rotary switching mechanism is provided outside the guide column 3. The rotary switching mechanism includes a filter cylinder 7 rotatably sleeved outside the guide column 3 and a motor 8 fixedly connected to the outer side of the middle of the cover plate 2. The output shaft of the motor 8 is fixedly connected to the middle of the filter cylinder 7. Four sealing baffles 9 are arranged circumferentially with equal arc on the outer side of the filter cylinder 7. The end face of the sealing baffle 9 away from the filter cylinder 7 is slidably connected to the inner wall of the circular treatment box 1 through a sealing strip.

[0026] In this embodiment, by setting up four filtration zones and adopting a simple rotating switching structure, alternating filtration and cleaning operations are achieved. Specifically, the four filtration zones work in turn, the structure is simple and reliable, and while ensuring continuous filtration, each filtration zone is thoroughly cleaned after use, greatly improving the working efficiency and reliability of the device.

[0027] like Figure 3 and Figure 4As shown, the guide channel 4 is axially opened inside the guide column 3 and located in the upper middle part of the guide column 3. An opening 5 is opened through the top of the guide column 3 and communicates with the guide channel 4. An opening 6 is opened inward at the bottom of the guide column 3. A spray cleaning mechanism is installed inside the opening 6. The spray cleaning mechanism includes nozzles 10 regularly arranged on the upper surface inside the opening 6 and a waste output shell 11 that penetrates the middle of the bottom of the circular processing box 1. A cutting fluid recovery pipe 12 and an air inlet pipe 13 are respectively installed at the upper and lower ends of the middle part of the side of the circular processing box 1 away from the cover plate 2. The cutting fluid recovery pipe 12 is connected to the lower part of the interior of the guide channel 4. The air inlet pipe 13 is connected to several nozzles 10 through an airflow channel opened inside the guide column 3. A vertical waste liquid input pipe 14 is fixedly installed at the middle of the top of the circular processing box 1.

[0028] In this embodiment, by setting the nozzle 10 downwards and cooperating with the internal airflow channel of the guide column 3, the problem of the jet nozzle being easily blocked by cutting fluid debris in the prior art is effectively solved. Specifically, the downward arrangement of the nozzle 10 makes the blowing direction opposite to the flow direction of the cutting fluid, avoiding the deposition of debris at the jet nozzle. At the same time, the high-pressure gas blowing from bottom to top can more effectively remove solid particles attached to the surface of the filter cartridge 7.

[0029] Working principle: When the waste cutting fluid containing metal shavings generated by the grinding machine enters the circular processing tank 1 through the waste fluid input pipe 14, the waste cutting fluid is first filtered through the filter cylinder 7 at the current working position. The filtered clean cutting fluid first enters the guide groove 4 through the opening 5, and then flows into the cutting fluid recovery pipe 12 for recycling. When the filter cylinder 7 reaches the preset working time, the motor 8 is started and the filter cylinder 7 is driven to rotate 90°, so that the adjacent clean filtration area rotates to the working position to continue the filtration operation. At this time, the replaced used filtration area will pass through the intermediate transition position with the rotation of the filter cylinder 7, and reach the lower clean position during the second rotation (the device needs to be rotated a second time when it is used for the first time, but with subsequent use, a new filtration area will reach the working position every time it rotates 90°, and the previously used filtration areas will reach the clean position in sequence). At this time, high-pressure gas is introduced through the air inlet pipe 13 and sprayed out from the nozzle 10 through the airflow channel inside the guide column 3 to perform reverse spray cleaning on the outer surface of the filter cylinder 7 in this area. The removed metal shavings are discharged from the device through the waste output shell 11 under the action of gravity.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
