After preliminary filtration, the cutting fluid enters the second water tank for storage. The second pumping component pumps the cutting fluid in the second water tank to the second filter component for further filtration. After further filtration, the cutting fluid enters the cooling tank 401 for cooling to reach the required operating temperature. After cooling, the qualified cutting fluid is pumped to the outside by the third pumping component for recycling. Furthermore, all components are connected by pipelines to facilitate the flow and transmission of the cutting fluid.

[0040] The integrated filtration and chip removal device of this utility model can deeply filter the cutting fluid discharged from the chip conveyor body 10 through a primary filtration system 20 and a secondary filtration system 30 to further remove waste chips. At the same time, the cutting fluid is cooled by a cooling system 40 and pumped out, which greatly improves the output quality of the cutting fluid, meets industrial needs, and is suitable for industrial applications.

[0041] In one specific embodiment, the first water tank is installed below the bottom of the chip conveyor body 10 and is connected to the first liquid outlet 101 of the chip conveyor body 10; the first pumping assembly includes a first liquid pump 201 installed above the first water tank for pumping the cutting fluid located in the first water tank; the first filtration assembly includes a vortex separator 202 connected to the output end of the first liquid pump 201.

The two first water tanks 203 are interconnected through a first connecting port 204 to form the first water tank. The first liquid pump 201 is located above one of the first water tanks 203 and is used to pump the cutting fluid in the first water tank to the vortex separator 202 for solid-liquid separation. Further, in this embodiment, the vortex separator 202 is located on the chain plate chip conveyor 102 of the chip conveyor body 10. During operation, the waste chips after solid-liquid separation return to the chip conveying chain plate of the chain plate chip conveyor 102 through the chip discharge port of the vortex separator 202, so as to be discharged again through the chip conveyor body 10. The discharge liquid after solid-liquid separation by the vortex separator 202 enters the second water tank through the second liquid outlet 205 of the vortex separator 202.

[0043] In one specific embodiment, the second water tank is installed below the chip conveyor body 10 and located to one side of the first water tank; the second pumping assembly includes a second pump 301 installed above the second water tank for pumping the cutting fluid in the second water tank to the second filter assembly.

Furthermore, the second outlet 205 of the vortex separator 202 is connected to one of the secondary water tanks 302 via a pipeline, and is used to output the first filtered cutting fluid to the secondary water tank.

[0044] In one specific embodiment, the second filtration assembly includes a filter cylinder 303; the filter cylinder 303 includes an outer cylinder 304 and a filter element 305 installed inside the outer cylinder 304; the side of the outer cylinder 304 is connected to the output end of the second liquid pump 301, and the bottom of the outer cylinder 304 is provided with a drain port 320; the side wall of the filter element 305 has filter holes that communicate with the outer cylinder 304, and the top of the filter element 305 is provided with a third liquid outlet 306 connected to the cooling system 40. Specifically, in this embodiment, during operation, the second liquid pump 301 pumps the cutting fluid located in the second water tank into the outer cylinder 304. At this time, the drain port 320 is closed, and then the cutting fluid enters the filter element 305 through the filter holes, and finally exits the filter element 305 from the third liquid outlet 306. Under the guidance of the pipeline, it flows to the cooling system 40. The waste chips remaining in the cutting fluid are blocked outside the filter element 305 and accumulate at the bottom of the outer cylinder 304. After accumulating to a certain extent, the drain port 320 is opened to remove the waste chips. The wastewater is discharged through the drain port 320. Further, the outer cylinder 304 is installed above one of the second water tanks 302 in this embodiment. A coaxial valve 307 connected to the drain port 320 is provided on one side of the drain port 320 to open and close the drain port 320 as needed.

Above a primary water tank 203, the cutting fluid in the primary water tank 203 is pumped to the vortex separator 202. In this embodiment, the outlet of the fourth liquid pump 50 is connected to the top of another primary water tank opposite to the primary water tank where the first liquid pump 201 is installed via a pipeline. This is used to flush the internal fine debris in the primary water tank connected to the fourth liquid pump 50 into the primary water tank where the first liquid pump 201 is installed during operation. The first liquid pump 201 is used to extract and filter the debris, so that no debris remains at the bottom of the primary water tank, thereby achieving water tank cleanliness and extending service life.

[0047] In one specific embodiment, the cooling system 40 includes a cooling tank 401 with a cooling pipe 402 inside; a third pumping component includes a third pump 403 connected to the cooling system for pumping the cooled liquid from the cooling tank 401 to the outside. Specifically, the cooling tank 401 is connected to the output end of the second filter component via a pipe.

The cooling pipe 402 contains the cooling liquid, and a refrigeration component 404 connected to the cooling pipe 402 is provided above the cooling tank 401 to achieve cooling circulation of the cooling liquid in the cooling pipe 402. This allows the cutting fluid to be effectively cooled by the cooling pipe 402 after entering the cooling tank 401, so that the cutting fluid meets the liquid temperature requirements for machining. After the cutting fluid has cooled, the third pump 403 pumps it from the cooling tank 401 to the outside for subsequent recycling. Furthermore, the outlet of the third liquid pump 403 is connected to the inlet of the oil manifold 406 via a high-pressure oil pipe or rigid pipe. The oil manifold 406 then distributes the cooled and filtered cutting fluid to the external system. Through this arrangement, the cutting fluid is pressurized by the pump unit to form a high-pressure outlet, thereby achieving chip breaking in deep hole machining and complex processes, playing a crucial role in protecting the cutting tools and improving product quality. Furthermore, in this embodiment, the cooling tank 401 is installed above one of the primary water tanks 203 for better structural distribution and improved structural compactness. It should be noted that the refrigeration component 404 is existing knowledge possessed by those skilled in the art, and therefore will not be described in detail here. Furthermore, the cooling tank 401 is equipped with a third float level gauge 405 for monitoring the liquid level.

[0048] In one specific embodiment, a first float level gauge 206 is provided above the first water tank. Specifically, the float of the first float level gauge 206 is located inside the first water tank and is used to monitor the level of the cutting fluid in the first water tank in real time. Further, in this embodiment, the first float level gauge 206 is located above one of the primary water tanks 203.

[0049] In one specific embodiment, a second float level gauge 311 is provided above the second water tank. Specifically, the float of the second float level gauge 311 is located inside the second water tank and is used to monitor the level of the cutting fluid in the second water tank in real time. Further, in this embodiment, the second float level gauge 311 is located above one of the secondary water tanks 302.

[0050] In one specific embodiment, the secondary filtration system further includes an oil-water separation component 321 installed above the second water tank for separating the cutting fluid located in the second water tank from the oil.

[0051] In one specific embodiment, the oil-water separation assembly 321 includes a first liquid receiving box 312, a second liquid receiving box 313, an oil guide belt 314, a drive unit, an oil scraper 315, a guide plate 316, and a connecting pipe 317; the first liquid receiving box 312 and the second liquid receiving box 313 are arranged side by side above the second water tank; the first liquid receiving box 312 has a first liquid receiving chamber and a second liquid receiving chamber that are interconnected at their bottoms, and the first liquid receiving chamber has a liquid guide port near the second liquid receiving box 313; the oil guide belt 314 is vertically installed on one side of the first liquid receiving box 312, and the oil guide belt 314... One end is located above the first liquid receiving chamber, and the other end is located inside the second water tank; the drive unit is connected to the oil guide belt 314 and is used to drive the oil guide belt 314 to rotate; the scraper 315 is installed above the first liquid receiving chamber and abuts against the oil guide belt 314, and is used to scrape the cutting fluid and oil on the surface of the oil guide belt 314 into the first liquid receiving chamber when the oil guide belt 314 rotates; the guide plate 316 is installed at the liquid guide port and is used to guide the oil in the first liquid receiving chamber to the second liquid receiving box 313; the connecting pipe 317 is installed in the second liquid receiving chamber and is connected to the second water tank. Specifically, in this embodiment, during operation, the drive unit drives the oil guide belt 314 to rotate, so that the oil guide belt 314 guides the cutting fluid mixed with grease in the second water tank to the top of the second water tank when rotating. Since the oil scraper 315 abuts against the oil guide belt 314, the oil scraper 315 scrapes off the grease and cutting fluid on the oil guide belt 314 and guides it into the first liquid receiving chamber. Since the density of oil is lower than that of cutting fluid, the grease will float on the surface of the cutting fluid. The bottoms of the first liquid receiving chamber and the second liquid receiving chamber are connected, so the cutting fluid in the first liquid receiving chamber will enter the second liquid receiving chamber from the bottom of the first liquid receiving chamber and finally return to the second water tank through the connecting pipe 317. The grease located above the cutting fluid will enter the second liquid receiving box 313 through the liquid guide port and the guide plate 316. Specifically, the height of the connecting pipe 317 is adjusted to a position slightly lower than the height of the liquid guide port, so as to facilitate the oil floating on the cutting fluid to flow out from the liquid guide port. Once the grease accumulates to a certain level in the second liquid receiving box 313, it can be extracted from the second liquid receiving box 313. This completes the grease separation in the second water tank. Furthermore, the oil scraper 315 is angled towards the first liquid receiving chamber, with its upper part abutting against the oil guide belt 314, thus scraping off the grease while guiding it into the first liquid receiving chamber.

[0052] In one specific embodiment, the drive unit includes drive wheels 318 mounted at both ends of the oil guide belt 314, and a servo motor 319 connected to the drive wheel 318 located above the second water tank, for driving the drive wheel 318 to rotate. Specifically, during operation, the servo motor 319 drives the oil guide belt 314 to rotate through the cooperation of the two drive wheels 318.

[0053] The integrated filtration and chip removal device of this utility model can deeply filter the cutting fluid discharged from the chip conveyor body 10 through a primary filtration system 20 and a secondary filtration system 30 to further remove waste chips. At the same time, the cutting fluid is cooled by a cooling system 40 and pumped out, which greatly improves the output quality of the cutting fluid, meets industrial needs, and is suitable for industrial applications.

[0054] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
