Description

Technical Field

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

[0002] In the field of mechanical processing, the process of cutting, grinding, shearing and drilling the blank involves cooling, cleaning, rust prevention and lubrication. Therefore, a large amount of cutting fluid is used. After a period of use, the cutting fluid will produce a large amount of particles due to cutting, grinding, shearing and drilling, making it difficult to recycle the waste cutting fluid and cannot be discharged directly.

[0003] For example, a cutting fluid purification and recovery treatment equipment with the announcement number CN222900398U includes a purification barrel, the upper end of the purification barrel is provided with a mounting pipe, the side wall of the mounting pipe is provided with a liquid inlet pipe, the lower end of the mounting pipe is provided with a connecting barrel inside the purification barrel, the lower end of the connecting barrel is provided with a No. 1 mounting plate, the upper end of the No. 1 mounting plate is provided with two groups of No. 1 filter screens around the connecting barrel, the middle of the No. 1 mounting plate is provided with multiple groups of leakage holes on the outer circle of the No. 1 filter screen, the lower end of the No. 1 mounting plate is provided with two groups of No. 2 filter screens, the lower ends of the two groups of No. 2 filter screens are provided with a No. 2 mounting plate, and the middle of the No. 2 mounting plate is provided with a discharge barrel. The two layers of filter screens are provided to purify the cutting fluid better. At present, the multi-axis machining centers on the market are basically like this The following configuration: screw conveyor + chain conveyor + scraper conveyor + recoil drum + oil remover + pump group + water tank, etc. Some also add a vortex separator for purification as a pre-filter of the central water outlet filter unit; however, no matter how it is composed, after the cutting fluid enters the water tank with chips, it flows horizontally with a small drop, and is finally pumped back to the machine tool by the liquid supply pump. This structural feature causes cast iron and powder chips to deposit in every corner of the water tank, and the accumulation becomes thicker and thicker, and also causes fine needle-shaped and thin-sheet chips of aluminum alloy to float on the liquid surface and fill every space of the water tank, thereby affecting the operation of the water tank and forcing the operator to stop production to clean the water tank, which in turn affects the efficiency of production and processing. Therefore, a multi-stage processing workstation for cutting fluid is proposed to solve the above-mentioned problems. Summary of the Invention

The cutting fluid passes through the outlet pipe and the top pipe and enters the interior of the upper cavity. The non-woven fabric intercepts 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 is closed, the air inlet valve is opened, and the storage The compressed air stored in the gas tank enters the upper cavity, presses the liquid retained in the upper cavity into the lower cavity, and at the same time dries the non-woven fabric and impurities.

The conveying chain plate 63 will drive the push plate 64 and the vertical rod 66 to move, and 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.

[0063] As more and more impurities are trapped, 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 is closed, the air inlet valve is opened, and the compressed air stored in the air tank enters the upper cavity 87, pressing the liquid retained in the upper cavity 87 into the lower cavity 81, while drying the non-woven fabric and impurities. At this time, the pressure in the upper cavity 87 will gradually decrease. When it drops to the set value, the air inlet valve is closed, and the driving cylinder 85 lifts the upper cavity 87 to the set position. The cloth-collecting motor 82 drives the winding roller 83 to rotate, and 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-collecting motor 82 stops running, and the water pump on the top of the tertiary liquid tank 4 pumps the clean liquid back to the processing center. The filter press assembly 8 can filter out impurities larger than 0.03 mm.

When rotating reversely, the precipitated chips and impurities in the liquid can be scraped out and discharged into the chip collection car 9. The flushing pipe 710 flushes the filter cartridge 77. Under the dual action of the flushing pipe 710 and the scraper plate 79, the impurities attached to the outside of the filter cartridge 77 can be removed to achieve self-cleaning. The circulation pump 10 extracts the liquid inside the secondary liquid tank 1 and outputs it respectively through the outlet pipe 11, branch pipe 12 and branch pipe 2 13. The first 12 is connected to the flushing pipe 710 for flushing the filter cartridge part 77. The branch pipe 2 13 is connected to the flushing pipe 19 for flushing the interior of the secondary liquid tank 1. The driving cylinder 85 drives the connecting plate 86 to press down, and 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. The top of the upper cavity 87 is installed with a pressure sensor and an air inlet valve. The top of the filter plate 89 is installed with a non-woven fabric. The upper cavity 87 forms a sealed cavity with the lower cavity 81 and the non-woven fabric. The cutting fluid passes through the outlet pipe 11 and the top pipe 17 and is input into the interior of the upper cavity 87. The non-woven fabric intercepts impurities in the liquid. The cloth-collecting motor 82 drives the winding roller 83 to rotate, and the winding roller 83 brings 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-collecting motor 82 stops running, and the water pump on the top of the tertiary liquid tank 4 pumps the clean liquid back to the machining center.
