Description

Technical Field

[0002] Chip conveyors are mainly used for chip removal in machine tool processing, separating the cut iron chips from the cutting fluid and discharging the iron chips to achieve the regeneration and reuse of the cutting fluid.

[0003] Traditional chip conveyors can only take away larger iron chips. Fine iron chips generated during the machine tool processing, such as iron chips smaller than 50mm, will flow into the water tank. Therefore, the iron chips in the water pump will gradually accumulate, causing damage to the water pump and affecting its service life. Therefore, the existing chip conveyor will use a roller chip conveyor to filter the fine iron chips from the cutting fluid in the water tank. However, the roller chip conveyor cannot filter out finer powder chips, resulting in residual deposition of fine powder chips in the water tank, increasing the number of water tank cleaning times, and fine powder chips are more likely to enter the cutting work with the flow of cutting fluid, resulting in increased wear of machine tool tools, reduced tool service life, and increased chances of workpiece scrapping.

[0027] The secondary water tank 11 is located on one side of the primary water tank 1, and the high-pressure water tank 13 is located above the primary water tank 1.

[0028] As shown in Figure 2 The primary water tank 1 is respectively provided with a liquid inlet 21 and a chip discharge port at both ends, the liquid inlet 21 is located above the chain belt 4, and the chip discharge port is located below the chain belt 4, the chain belt 4 comprises two annular conveying chains which are synchronously driven and a plurality of scrapers, the two ends of the plurality of scrapers are fixed to the two conveying chains and move synchronously with the conveying chains, the scrapers are L-shaped and are attached to the bottom of the primary water tank 1 to scrape off iron chips, a chip removal tank 16 with an opening door at the bottom is further arranged below the chip discharge port, the bottom of the chip removal tank 16 is provided with a backflow pipe 17, the backflow pipe 17 is provided with a filter screen, so that the residual cutting fluid can flow back to the primary water tank 1, thereby saving cutting fluid. The liquid inlet 21 and the chip discharge port are rotatably connected with sprockets, the drum filter 2 is provided with sprockets at both ends, the filter screen is arranged on the outer periphery of the drum filter 2, the motor 3 drives the sprockets to rotate, thereby driving the two conveying chains to synchronously drive, and at the same time, the drum filter 2 rotates, thereby driving the scrapers to sequentially scrape the cutting fluid and iron chips on the bottom of the primary water tank 1 towards the liquid inlet 21, the scrapers scrape off the iron chips, the movement of the cutting fluid is avoided, the iron chips sink to the bottom, the cutting fluid flows through the drum filter 2 and is filtered by the drum filter 2, and at the same time, the top of the scraper also contacts the filter screen on the outer periphery of the drum filter 2 when the scraper moves, thereby scraping off the iron chips on the filter screen, and the regeneration of the drum filter 2 is realized in cooperation with the backwashing pump 5.

[0029] As shown in Figure 3As shown, the drum filter 10 mainly adopts a drum paper tape filter, which is a universal supporting filtering equipment, mainly used for cooling liquid filtration in metal grinding or other processing, and is also suitable for removing impurities in cleaning fluid, industrial water, organic solution and other solutions in the rough parts cleaning system; it consists of a unwinding roller 18 wound with a paper tape, a rotating shaft and a winding roller driven to rotate by a winding motor 20, and a turntable is provided at both ends of the rotating shaft. The paper tape extends from the unwinding roller 18 and passes around the turntable downward, and then passes around the winding roller upward. The rotating shaft is hollow and connected to the lifting pump 9. The outer periphery of the rotating shaft is evenly provided with spray holes. Cutting fluid and iron chips are sprayed from the spray holes to the paper tape, and rely on the gravity of the liquid itself to pass through the paper tape. The iron chips remain above the paper tape, thereby achieving the purpose of purifying the liquid. Therefore, it is only necessary to drive the winding roller to rotate with the winding motor 20 to drive the paper tape to move, so that the clean paper tape replaces the waste paper tape, and the waste paper tape is stored in the waste paper box 16. The paper tape can also be replaced with a filter cloth.

[0030] like Figure 4 As shown, an eddy current separator 15 is further provided between the eddy current pump and the high-pressure water tank. The two ends of the eddy current separator 15 are respectively connected to the eddy current pump 12 and the high-pressure water tank 13. The bottom of the eddy current separator 15 is connected to the primary water tank 1. The cutting fluid in the primary water tank 1 is pumped into the eddy current separator 15 by the eddy current pump 12. The working principle of the eddy current separator 15 is mainly to achieve solid-liquid separation by using the centripetal force field generated by the rotating eddy current. When the cutting fluid is introduced into the separation chamber of the eddy current separator 15, the cutting fluid and iron chips form a vortex in the separation chamber. Due to inertia, the iron chips are deposited to the lower part of the separator along the radial line of the vortex and return to the primary water tank, while the clean cutting fluid is discharged into the high-pressure water tank 13 through the upper part of the separator. The eddy current separator 15 used in this embodiment is a DC-2 eddy current separator manufactured by Ruigoux.

[0031] The cutting fluid containing iron chips first enters the primary filter unit, and the drum filter 2 performs primary filtration on the cutting fluid, filters out the larger iron chips in the cutting fluid and discharges the iron chips that have settled on the bottom from the chip discharge port through the scraper. At this time, the cutting fluid enters the primary water tank 1 for storage, and then the secondary filter unit works in a cycle, and the cutting fluid in the primary water tank 1 is continuously pumped into the drum filter 10 through the lifting pump 9. The drum filter 10 performs secondary filtration on the cutting fluid. The secondary filtration is a continuous filtration cycle operation, gradually filtering out the fine powder chips in the cutting fluid in the primary water tank 1, and the secondary filter unit 10 performs secondary filtration on the cutting fluid. The filtered cutting fluid is stored in the secondary water tank 11, and the iron filings are discharged to the waste paper box 19 along with the paper tape. When the liquid level in the secondary water tank 11 is too high, it will overflow into the primary water tank 1 through the overflow pipe. Regularly moving the filter sheets such as the paper tape in the drum filter 10 can achieve the normal use of the drum filter 10; then the tertiary filtration unit works, pumping the cutting fluid in the primary water tank 1 into the high-pressure water tank 13, and performing three-stage filtration on the cutting fluid. The eddy current separator 15 performs centrifugal filtration on the cutting fluid to remove the residual iron filings in the cutting fluid and keep the cutting fluid clean.

[0032] In order to make the cutting fluid sprayed by the backwashing pipe 6 uniformly sprayed on the screen of the drum filter 2, remove the iron filings on the outer surface of the drum filter 2, and realize the regeneration of the drum filter 2, a plurality of spray pipes are arranged on the backwashing pipe 6.

[0033] The backwashing pump 5 is communicated with a flushing pipe arranged at the middle part of the bottom of the primary water tank 1, and a plurality of nozzles are arranged on the flushing pipe; the fine powder accumulated in the primary water tank 1 will be settled and accumulated at the bottom of the primary water tank 1 due to its own gravity, and due to its small size, the powder layer at the bottom of the primary water tank 1 is very dense, which is difficult to clean and easy to block the lifting pump 9 and the backwashing pump 5, so the flushing pipe arranged at the bottom of the primary water tank 1 sprays liquid flow through the plurality of nozzles to prevent the powder from being settled and accumulated.

[0034] The primary water tank 1 is provided with a side flushing pump; since the flushing pipe is arranged at the bottom of the primary water tank 1, the flow rate is greatly weakened when the liquid flow reaches the side wall of the primary water tank 1, and the powder at the bottom of the side wall of the primary water tank 1 cannot be flushed, and the flushing pump is arranged to directly flush the side wall of the primary water tank 1, thereby further preventing the powder in the primary water tank 1 from being settled and accumulated.

[0035] The liquid level alarm 8 is arranged in the primary water tank 1 and the high-pressure water tank 13; the liquid level alarm 8 in the primary water tank 1 is used to avoid the liquid level in the primary water tank 1 being too low to cause insufficient cutting fluid; and the liquid level alarm 8 in the high-pressure water tank 13 is used to avoid the liquid level in the high-pressure water tank 13 being too high.

[0036] The composite drum paper belt filtering and chip removal machine of the embodiment adopts the drum filter 2 to perform primary filtering, filters the iron filings with large size in the cutting fluid, and removes the iron filings through the chain belt 4 and discharges the iron filings from the chip removal port, and cooperates with the drum filter 10 to perform secondary filtering on the cutting fluid in the primary water tank 1, removes the fine powder iron filings in the cutting fluid, and further cooperates with the vortex pump 12 and the vortex separator 15 to perform centrifugal filtering on the cutting fluid, thereby removing the residual iron filings in the cutting fluid, maintaining the cleanliness of the cutting fluid, prolonging the service life of the cutting fluid, reducing the accumulation of fine powder in the water tank, and reducing the cleaning frequency of the water tank.

[0037] The above is only a preferred embodiment of the present application, and does not limit the present application in any form, and any simple modification, equivalent change and modification made according to the technical essence of the present application to the above embodiment are within the scope of the technical scheme of the present application.
