Description

Technical Field

[0001] The present invention relates to the technical field of cutting fluid recovery and treatment, and particularly to a workstation for multi-stage treatment of cutting fluid. Background Art

[0002] In the field of machining, during the processes of cutting, grinding, shearing, and drilling of workpieces by tools, processes such as cooling, cleaning, rust prevention, and lubrication are involved, so a large amount of cutting fluid is used. After the cutting fluid is used for a period of time, due to the generation of a large amount of particles during cutting, grinding, shearing, and drilling, the waste cutting fluid is difficult to recycle and cannot be directly discharged.

[0003] For example, a cutting fluid purification and recovery treatment device with the publication number of CN222900398U includes a purification barrel. An installation pipe is arranged at the upper end of the purification barrel, a liquid inlet pipe is arranged on the side wall of the installation pipe, a connecting cylinder is arranged inside the purification barrel at the lower end of the installation pipe, a first mounting plate is arranged at the lower end of the connecting cylinder, two groups of first filter nets are arranged around the connecting cylinder at the upper end of the first mounting plate, a plurality of liquid leakage holes are arranged outside the first filter nets in the middle of the first mounting plate, two groups of second filter nets are arranged at the lower end of the first mounting plate, a second mounting plate is arranged at the lower end of the two groups of second filter nets, and a discharge cylinder is arranged in the middle of the second mounting plate. Through the two-layer filter net arranged, the purification treatment effect of the cutting fluid is better. At present, most multi-axis machining centers on the market are basically configured as follows: screw conveyor + chain plate conveyor + scraper conveyor + backwashing rotary cylinder + oil removal machine + pump set + water tank, etc. Some also add a vortex separator for purification as the pre-filter of the central water outlet filtering unit; however, no matter how it is composed, after the cutting fluid with chips enters the water tank, it flows horizontally under a small drop, and finally is pumped back to the machine tool by the supply pump. This structural composition feature causes cast iron and powdered chips to deposit in all corners of the water tank and accumulate thicker and thicker, and also causes aluminum alloy fine needle-shaped and flaky chips to float on the liquid surface and fill all spaces of the water tank, thus affecting the operation of the water tank, making the operator have to stop production for water tank cleaning, and then affecting the production and processing efficiency. Therefore, a workstation for multi-stage treatment of cutting fluid is proposed to solve the above-mentioned problems. Summary of the Invention

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By setting a conveying component and a cleaning component, the chips and cutting fluid coming out of the machining center enter the separator through the conveying component. The chips larger than 5 mm are carried into the chip collecting cart by the conveying chain plate. The conveying chain plate drives the push plate and the vertical rod to move, the vertical rod drives the rotating rod to move. When the rotating rod contacts the side rod, it is squeezed by the side rod, so that the rotating rod drives the vertical rod and the torsion spring to rotate. When the rotating rod separates from the side rod, the elastic force of the torsion spring drives the vertical rod and the rotating rod to reset. Through the intermittently arranged side rods, the rotating rod breaks up the lumps in the cutting fluid, which is convenient for subsequent conveying into the chip collecting cart. The remaining impurities and cutting fluid are pumped into the circulation pipe by the impurity pump and then input into the cleaning box through the circulation pipe. The driving motor is started, and the driving motor drives the driving shaft and the transmission sprocket to rotate. The transmission sprocket drives the driving chains on both sides to rotate. The driving chains drive the filter cylinder sprocket to rotate and the separation plate to convey. The driving motor can realize the forward and reverse rotation switching. When rotating forward, the floating chips in the liquid can be scraped out. When rotating reverse, the precipitated chips and impurities in the liquid can be scraped out and discharged into the chip collecting cart. The flushing pipe flushes the filter cylinder part. Under the dual action of the flushing pipe and the chip scraping plate, the impurities attached to the outer side of the filter cylinder part can be removed to realize self-cleaning. The circulating pump extracts the liquid inside the secondary liquid tank and outputs it through the water outlet pipe, branch pipe 1 and branch pipe 2 respectively. Among them, branch pipe 1 is connected to the flushing pipe and is used for flushing the filter cylinder part. Branch pipe 2 is connected to the scouring pipe and is used for flushing the interior of the secondary liquid tank to prevent chips from accumulating in the secondary liquid tank, solving the problem that after the cutting fluid with chips enters the water tank, the cast iron and powdery chips are deposited in the corners of the water tank, and the fine needle-shaped and thin sheet-shaped chips float on the liquid surface, affecting the normal operation of the water tank; 2. By setting up a pressure filtration component, the driving cylinder drives the connecting plate to press downwards. The connecting plate drives the upper cavity to press downwards. The upper cavity is tightly sealed with the lower cavity through a sealing plate. A pressure sensor and an air inlet valve are installed at the top of the upper cavity. A non-woven fabric is installed at the top of the filter plate. The upper cavity, the lower cavity and the non-woven fabric form a sealed cavity. The cutting fluid passes through the water outlet pipe and the top pipe and is input into the interior of the upper cavity. The non-woven fabric intercepts the impurities in the liquid. As more and more impurities are intercepted, the permeability of the non-woven fabric decreases, and the pressure in the upper cavity will gradually increase. After the pressure reaches the set value, the valve of the top pipe closes, and the air inlet valve opens. The compressed air stored in the air storage tank enters the upper cavity, presses the liquid remaining in the upper cavity into the lower cavity, and at the same time dries the non-woven fabric and the impurities. At this time, the pressure in the upper cavity will gradually decrease. After it drops to the set value, the air inlet valve closes, and the driving cylinder lifts the upper cavity to the set position. The cloth receiving motor drives the winding roller to rotate, and the winding roller takes out the dirty non-woven fabric. The impurities on the non-woven fabric enter the external collection box. When the new non-woven fabric reaches the set length, the cloth receiving motor stops running. The water pump at the top of the three-stage liquid tank pumps the clean liquid back to the machining center. The pressure filtration component can filter out impurities larger than 0.03 mm.

[0035] Embodiment 1: As Figures 1 - 3 shown, the chips and cutting fluid from the machining center enter the separator 5 through the conveying assembly 6. The chips larger than 5 mm are carried into the chip collector 9 by the conveying chain plate 63. The conveying chain plate 63 drives the push plate 64 and the vertical rod 66 to move. The vertical rod 66 drives the rotating rod 67 to move. When the rotating rod 67 contacts the side rod 65, it is squeezed by the side rod 65, so that the rotating rod 67 drives the vertical rod 66 and the torsion spring 68 to rotate. When the rotating rod 67 separates from the side rod 65, the elastic force of the torsion spring 68 drives the vertical rod 66 and the rotating rod 67 to reset. Through the spaced side rods 65, the rotating rod 67 breaks up the lumps in the cutting fluid, which is convenient for subsequent conveyance into the chip collector 9.

[0036] The remaining impurities and cutting fluid are pumped into the circulation pipe 15 by the impurity pump 14, and then input into the cleaning tank 2 by the circulation pipe 15.

Under the dual action of the flushing pipe 710 and the chip scraping plate 79, the impurities attached to the outside of the filter cylinder part 77 can be removed, realizing self-cleaning.

[0037] The circulation pump 10 extracts the liquid inside the secondary liquid tank 1 and outputs it respectively through the water outlet pipe 11, the first branch pipe 12 and the second branch pipe 13. Among them, the first branch pipe 12 is connected to the flushing pipe 710 for flushing the filter cylinder part 77. The second branch pipe 13 is connected to the flushing pipe 19 for flushing the inside of the secondary liquid tank 1, preventing chips from accumulating in the secondary liquid tank 1, and solving the problem that after the cutting fluid with chips enters the water tank, the cast iron and powdery chips are deposited in all corners of the water tank, and the fine needle-shaped and thin sheet-shaped chips float on the liquid surface, affecting the normal operation of the water tank.

[0038] One side of the top of the secondary liquid tank 1 is equipped with an ozone generator and an oxygenation pipeline, which can sterilize the liquid in the secondary liquid tank 1 to prevent the liquid from deteriorating. Ozone sterilization has the characteristics of high efficiency, high cleanliness, convenience, economy, etc. It can oxidize and decompose the enzymes required for glucose inside bacteria, causing the bacteria to die out; the oxygenation pipeline adds compressed air into the secondary liquid tank 1 to oxygenate the cutting fluid and kill the anaerobic bacteria that cause the cutting fluid to deteriorate, extending the service life of the cutting fluid.

[0039] At the top of the secondary liquid tank 1, a belt oil skimmer is also installed, which can remove the floating oil in the liquid tank.

[0040] At the top of the tertiary liquid tank 4, a pressure filter assembly 8 is provided. The pressure filter assembly 8 includes a lower cavity 81 fixedly installed at the top of the tertiary liquid tank 4. The lower cavity 81 is communicated with the tertiary liquid tank 4. At one side of the top of the lower cavity 81, a cloth receiving motor 82 is fixedly installed. The output end of the cloth receiving motor 82 is fixedly installed with a winding roller 83 through a speed reducer. The winding roller 83 is rotatably installed at one side of the top of the tertiary liquid tank 4.

[0041] At the top of the tertiary liquid tank 4, a mounting frame 84 is also fixedly installed. In the middle of the top of the mounting frame 84, a driving cylinder 85 is fixedly installed. The output end of the driving cylinder 85 is fixedly connected with a connecting plate 86. The bottom end of the connecting plate 86 is fixedly connected with an upper cavity 87.

[0043] Embodiment 2: As Figures 4 - 7 shown, the driving cylinder 85 drives the connecting plate 86 to press down. The connecting plate 86 drives the upper cavity 87 to press down. The upper cavity 87 is tightly sealed with the lower cavity 81 through the sealing plate 88. A pressure sensor and an air inlet valve are installed at the top of the upper cavity 87. A non-woven fabric is installed at the top of the filter plate 89. The upper cavity 87, the lower cavity 81 and the non-woven fabric form a sealed cavity. The cutting fluid passes through the water outlet pipe 11 and the top pipe 17 and is input into the inside of the upper cavity 87. The non-woven fabric intercepts the impurities in the liquid.

[0044] As more and more intercepted impurities accumulate, the permeability of the non-woven fabric decreases, and the pressure in the upper cavity 87 will gradually increase. After the pressure reaches the set value, the valve of the top pipe 17 closes, and the air inlet valve opens. The compressed air stored in the air storage tank enters the upper cavity 87, presses the liquid remaining in the upper cavity 87 into the lower cavity 81, and at the same time dries the non-woven fabric and the impurities. At this time, the pressure in the upper cavity 87 will gradually decrease. After it drops to the set value, the air inlet valve closes, the driving cylinder 85 lifts the upper cavity 87 to the set position, the cloth receiving motor 82 drives the winding roller 83 to rotate, the winding roller 83 takes out the dirty non-woven fabric, and the impurities on the non-woven fabric enter the external collection box. When the new non-woven fabric reaches the set length, the cloth receiving motor 82 stops running, and the water pump at the top of the tertiary liquid tank 4 pumps the clean liquid back to the machining center. The pressure filter assembly 8 can filter out impurities larger than 0.03 mm.

[0045] Working principle: When using this device, first, as Figures 1 - 14As shown, the chips and cutting fluid from the machining center enter the separator 5 through the conveying assembly 6. Chips larger than 5 mm are carried into the chip collector 9 by the conveying chain plate 63. The rotating rod 67 breaks up the lumps in the cutting fluid to facilitate subsequent conveyance into the chip collector 9. The remaining impurities and cutting fluid are pumped into the circulation pipe 15 by the impurity pump 14, and then input into the cleaning tank 2 through the circulation pipe 15. Start the driving motor 71 to work. The driving motor 71 can achieve forward and reverse rotation switching. When rotating forward, it can scrape out the floating chips in the liquid. When rotating in reverse, it can scrape out the precipitated chips and impurities in the liquid and discharge them into the chip collector 9. The flushing pipe 710 flushes the filter cartridge part 77. Under the dual action of the flushing pipe 710 and the chip scraping plate 79, the impurities attached to the outer side of the filter cartridge part 77 can be removed to achieve self-cleaning. The circulating pump 10 extracts the liquid in the secondary liquid tank 1 and outputs it respectively through the water outlet pipe 11, the first branch pipe 12 and the second branch pipe 13. Among them, the first branch pipe 12 is connected to the flushing pipe 710 for flushing the filter cartridge part 77, and the second branch pipe 13 is connected to the flushing pipe 19 for flushing the inside of the secondary liquid tank 1. The driving cylinder 85 drives the connecting plate 86 to press down. The connecting plate 86 drives the upper cavity 87 to press down. The upper cavity 87 is tightly sealed with the lower cavity 81 through the sealing plate 88. A pressure sensor and an air inlet valve are installed at the top of the upper cavity 87. A non-woven fabric is installed on the top of the filter plate 89. The upper cavity 87, the lower cavity 81 and the non-woven fabric form a sealed cavity. The cutting fluid passes through the water outlet pipe 11 and the top pipe 17 and is input into the inside of the upper cavity 87. The non-woven fabric intercepts the impurities in the liquid. The cloth collecting motor 82 drives the winding roller 83 to rotate. The winding roller 83 takes out the dirty non-woven fabric. The impurities on the non-woven fabric enter the external collecting box. When the new non-woven fabric reaches the set length, the cloth collecting motor 82 stops running. The water pump on the top of the tertiary liquid tank 4 pumps the clean liquid back to the machining center.
