Description

Technical Field

[0001] This invention relates to the field of solid-liquid separation technology, and in particular to a solid-liquid separation device for processing machine tools. Background Technology

[0002] Machine tools are commonly used equipment in industrial applications for machining metal parts. When turning metal parts, machine tools generate a lot of heat, which can easily cause high-temperature deformation of the cutting tool and the workpiece surface. Therefore, coolant is needed to cool the cutting tool and the workpiece surface during turning. The coolant that has washed the workpiece falls into the machine tool and is collected for recycling.

[0003] Patent document CN2022216876472 discloses a coolant filtration device for a five-axis tool grinding machine for alloy cutting tool processing. The device includes a cooling tank, with a cleaning component driven by a drive assembly on the bottom surface of the inner wall of the cooling tank. A threaded sleeve fixed to the outer surface of the cleaning component is provided between two sliding sleeves, and the threaded sleeve is threadedly connected to a lead screw. A cleaning brush fixed to the outer surface of the cleaning component is tightly fitted to the lower surface of the filter screen. By setting the drive assembly inside the cooling tank and the cleaning component driven by the drive assembly, the cooling tank can collect metal shavings during use.

[0004] However, in actual use, the inventors discovered that when the coolant flows towards the filter plate at a specific flow rate, some of the liquid rebounds and accumulates on one side of the filter plate. Furthermore, as filter residue accumulates on the filter plate without timely cleaning, the amount of liquid accumulated on one side of the filter plate increases, reducing the amount of coolant filtered out and making it difficult to supply the machine tool with circulating coolant, thus affecting the normal operation of the machine tool. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a solid-liquid separation device for processing machine tools. This device can divert excess liquid that has not been discharged from the arc-shaped filter plate for secondary filtration, ensuring the unobstructed flow of the arc-shaped filter plate, increasing the liquid filtration rate to meet the cooling requirements of the machine tool, and automatically cleaning the filter residue on the arc-shaped filter plate by means of liquid flow, preventing clogging and ensuring the amount of liquid filtered out by the arc-shaped filter plate. This solves the technical problem of existing filter plates accumulating more and more liquid on one side, reducing the amount of filtered coolant, making it difficult to supply the machine tool with circulating coolant, and affecting the normal operation of the machine tool.

The slag removal assembly includes a slag removal unit rotatably disposed inside the temporary storage chamber for transferring excess liquid and a slag discharge unit disposed outside the filter box for cleaning the slag removal unit. Liquid flows into the annular channel from the inlet pipe and passes through two sets of arc-shaped filter plates in sequence. A portion of the liquid is filtered by the arc-shaped filter plates and discharged from the outlet unit. The remaining liquid that is not discharged in time continues to flow along the annular channel to the chip suction assembly. The liquid that subsequently flows into the annular channel washes the arc-shaped filter plates and carries the filter residue to the chip suction assembly. The chip suction assembly cleans and discharges the metal chips in the liquid, while accelerating the excess liquid that is not discharged in time. The accelerated excess liquid impacts the bottom of the annular channel in segments, agitating the filter residue accumulated at the bottom of the annular channel and causing it to rise into the temporary storage chamber.

[0012] Preferably, the rotation direction of the second rotating shaft is opposite to the flow direction of the liquid in the annular channel, and the rotation speed of the second rotating shaft is greater than the flow speed of the liquid in the annular channel, so that the blade can accelerate the liquid flowing to the connection between the first round box and the annular channel, and also ensure that the arc-shaped electromagnet block has more time to adsorb metal shavings in the liquid at the connection between the first round box and the annular channel.

[0013] Preferably, the cleaning assembly includes two sets of scrapers that are slidably disposed via grooves and axially symmetrically disposed inside the annular channel for cleaning the arc-shaped filter plate; a third rotating shaft rotatably disposed on the outer side of the filter box; two sets of rotating rods axially symmetrically disposed on the third rotating shaft; an electromagnet plate disposed at the end of the rotating rod; a sheet magnet disposed at the end of the scraper; two sets of arc-shaped holes axially symmetrically disposed on the side of the filter box; a slider disposed on the rotating rod and slidably engaged with the arc-shaped hole; a third elastic element disposed between the slider and the end of the arc-shaped hole; a transmission gear disposed at the end of the third rotating shaft; a fourth rotating shaft rotatably disposed on the outer side of the filter box; and a half-gear disposed on the fourth rotating shaft for driving the transmission gear.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0032] Example 1 like Figures 1-11 As shown, a solid-liquid separation device for processing machine tools includes a filter assembly 1, and a chip suction assembly 2, a slag removal assembly 3, and a cleaning assembly 4 disposed inside the filter assembly 1. The filter assembly 1 includes a filter box 11, an annular channel 12 disposed inside the filter box 11 for supplying liquid flow, two sets of arc-shaped filter plates 13 symmetrically opened on the outer wall of the annular channel 12, a storage chamber 14 extending upward along the bottom of the annular channel 12 for temporarily storing excess liquid, an inlet pipe 15 disposed on the outer wall of the filter box 11 and disposed along the tangential direction of the annular channel 12, and an outlet unit 16 disposed on the outer wall of the filter box 11. The slag removal assembly 3 includes a slag removal unit 31 rotatably disposed inside the temporary storage chamber 14 for transferring excess liquid and a slag discharge unit 32 disposed outside the filter box 11 for cleaning the slag removal unit 31. In this embodiment, by using the filter assembly 1 and the slag removal assembly 3 together, on the one hand, excess liquid that has not been discharged from the arc-shaped filter plate 13 can be diverted away for secondary filtration, preventing excess liquid from accumulating on one side of the arc-shaped filter plate 13, ensuring the unobstructed flow of the arc-shaped filter plate 13, and improving the filtration effect of the arc-shaped filter plate 13. The sequential staged filtration can increase the filtration speed of the liquid to meet the cooling requirements of the machine tool. On the other hand, the liquid flow can be used to automatically clean the filter slag on the arc-shaped filter plate 13, flushing the filter slag to the chip suction assembly 2 and the slag removal assembly 3 for collection, preventing the arc-shaped filter plate 13 from becoming clogged, and ensuring the amount of liquid filtered out by the arc-shaped filter plate 13.

[0033] In detail, firstly, the liquid flows into the annular channel 12 from the inlet pipe 15 and passes through two sets of arc-shaped filter plates 13 in sequence. After being filtered by the arc-shaped filter plates 13, part of the liquid is discharged from the outlet unit 16. The other part of the liquid that is not discharged in time continues to flow along the annular channel 12 to the position of the dust collection component 2. The liquid that subsequently flows into the annular channel 12 washes the arc-shaped filter plates 13 and carries the filter residue to the position of the dust collection component 2. The dust collection component 2 cleans and discharges the metal shavings in the liquid, and at the same time accelerates the excess liquid that is not discharged in time. The accelerated excess liquid impacts the bottom of the annular channel 12 in segments, agitating the filter residue accumulated at the bottom of the annular channel 12 and raising it to the temporary storage chamber 14. The slag removal unit 31 collects the filter residue and adsorbs and transfers the excess liquid in the temporary storage chamber 14.

[0034] Furthermore, such as Figures 1-2 and Figures 6-8 As shown, the chip suction assembly 2 includes a chip suction unit 21 disposed on the top of the filter box 11 and a chip discharge unit 22 disposed on the chip suction unit 21; The dust collection unit 21 includes a first circular box 211 disposed on the top of the filter box 11 and connected to the annular channel 12, a second rotating shaft 212 rotatably disposed inside the first circular box 211, several sets of support rods 213 disposed on the second rotating shaft 212, several sets of arc-shaped electromagnet blocks 214 disposed between the ends of the support rods 213 and spliced ​​together to form a circle, several sets of blades 215 respectively disposed at the connection of two adjacent arc-shaped electromagnet blocks 214 and used to accelerate the liquid, electric contact pieces 216 disposed on the inner wall of the arc-shaped electromagnet blocks 214, and electric contact strips 217 disposed on the inner side of the first circular box 211. The chip removal unit 22 includes a second round box 221 disposed on the top of the first round box 211, a cylindrical magnet block 222 rotatably disposed inside the second round box 221, a scraper block 223 disposed on the inner side wall of the second round box 221 for scraping metal chips from the cylindrical magnet block 222, a chip removal channel 224 disposed on the outer wall of the first round box 211, a chip collection box 225 disposed on the outer wall of the first round box 211 and located at the lower port of the chip removal channel 224, and a stepper motor 226 disposed on the outer side of the second round box 221 for driving the cylindrical magnet block 222.

[0035] It should be noted that the rotation direction of the second rotating shaft 212 is opposite to the flow direction of the liquid in the annular channel 12. The rotation speed of the second rotating shaft 212 is greater than the flow speed of the liquid in the annular channel 12, so that the blade 215 can accelerate the liquid flowing to the connection between the first circular box 211 and the annular channel 12, and also ensure that the arc-shaped electromagnet block 214 has more time to adsorb metal shavings in the liquid at the connection between the first circular box 211 and the annular channel 12. It should also be noted that the second rotating shaft 212 and the cylindrical magnet block 222 rotate in opposite directions at the same speed through the transmission of pulleys and belts, which ensures that the cylindrical magnet block 222 has more time to adsorb metal shavings on the arc-shaped electromagnet block 214.

[0036] In this embodiment, the combination of the dust suction component 2 and the slag removal component 3 can, on the one hand, automatically adsorb metal dust from the liquid without affecting the flow of the liquid, and can promptly discharge the metal dust for unified collection, ensuring the continuity of the dust suction work; on the other hand, it can accelerate the excess liquid, and the accelerated excess liquid impacts the bottom of the annular channel 12 in segments, agitating the filter residue accumulated at the bottom of the annular channel 12 and raising it into the temporary storage chamber 14, preventing the filter residue from accumulating at the bottom of the annular channel 12 and facilitating the operation of the slag removal component 3.

[0037] In detail, liquid flows into the annular channel 12 from the inlet pipe 15 at a specific speed. A portion of the liquid is filtered by the arc-shaped filter plate 13 and discharged from the outlet unit 16. The remaining liquid, not discharged in time, continues to flow along the annular channel 12 to the chip collection assembly 2. The subsequent liquid flowing into the annular channel 12 washes the arc-shaped filter plate 13 and carries the filter residue to the chip collection assembly 2. Then, the stepper motor 226 drives the cylindrical magnet block 222 to rotate. The cylindrical magnet block 222 drives the second rotating shaft 212 to rotate in the same direction at the same speed via a pulley and belt. This causes the second rotating shaft 212 to rotate the arc-shaped electromagnet block 214 via the support rod 213. After the arc-shaped electromagnet block 214 rotates to the position of the contact bar 217, the arc-shaped electromagnet block... When the contact piece 216 of the arc-shaped electromagnet 214 contacts the contact strip 217, the arc-shaped electromagnet 214 becomes magnetic after being energized, causing it to magnetically attract metal shavings from the liquid. At the same time, the blade 215 on the outer side of the arc-shaped electromagnet 214 accelerates the liquid. The accelerated and segmented liquid continues to flow in the annular channel 12. Meanwhile, after the contact piece 216 of the arc-shaped electromagnet 214 detaches from the contact strip 217, the arc-shaped electromagnet 214 loses its magnetism. The cylindrical magnet 222 magnetically attracts and cleans the metal shavings on the arc-shaped electromagnet 214. Then, the metal shavings on the cylindrical magnet 222 are scraped off by the scraper 223. The scraped metal shavings fall from the chip discharge channel 224 into the chip collection box 225 for unified collection.

[0038] Furthermore, such as Figure 2 , Figure 4 and Figure 7 As shown, the cleaning assembly 4 includes two sets of scraper blades 41 that are slidably disposed in the annular channel 12 and are used to clean the arc-shaped filter plate 13, respectively; a third rotating shaft 42 that is rotatably disposed on the outer side of the filter box 11; two sets of rotating rods 43 that are axially symmetrically disposed on the third rotating shaft 42; an electromagnet plate disposed at the end of the rotating rod 43; a sheet magnet disposed at the end of the scraper blade 41; two sets of arc-shaped holes 44 that are axially symmetrically disposed on the side of the filter box 11; a slider disposed on the rotating rod 43 and slidably engaged with the arc-shaped hole 44; a third elastic element 45 disposed between the slider and the end of the arc-shaped hole 44; a transmission gear 46 disposed at the end of the third rotating shaft 42; a fourth rotating shaft 47 that is rotatably disposed on the outer side of the filter box 11; and a half-gear 48 disposed on the fourth rotating shaft 47 and used to drive the transmission gear 46.

[0039] It should be noted that the second rotating shaft 212 and the fourth rotating shaft 47 rotate in opposite directions through a pulley and belt transmission. The speed of the fourth rotating shaft 47 is less than that of the second rotating shaft 212 through a reduction gear. The fourth rotating shaft 47 drives the third rotating shaft 42 to rotate in the opposite direction through a half-gear 48 and a transmission gear 46. That is, the third rotating shaft 42 rotates in the same direction as the second rotating shaft 212. The second rotating shaft 212 is opposite to the flow direction of the liquid in the annular channel 12. Thus, the third rotating shaft 42 is also opposite to the flow direction of the liquid in the annular channel 12. This causes the scraper 41 to scrape the arc-shaped filter plate 13 in the opposite direction, further cleaning the filter residue on the arc-shaped filter plate 13. It is worth mentioning that the two sides of the scraper 41 are set as bevels to reduce resistance to liquid flow.

[0040] In this embodiment, the cleaning component 4 can scrape the arc-shaped filter plate 13 in the opposite direction to the liquid flow in the annular channel 12, and further clean the filter residue on the arc-shaped filter plate 13.

[0041] In detail, the second rotating shaft 212 drives the fourth rotating shaft 47 to rotate in the opposite direction through the transmission of pulleys and belts. The fourth rotating shaft 47 intermittently drives the third rotating shaft 42 to rotate in the opposite direction through the half-gear 48 and the transmission gear 46, so that the third rotating shaft 42 drives the rotating rod 43 to rotate intermittently. The rotating rod 43 drives the scraper 41 to scrape off the arc-shaped filter plate 13 intermittently through the electromagnet plate and the sheet magnet block. The rotating rod 43 drives the scraper 41 to reset through the drive of the third elastic element 45.

[0042] Furthermore, such as Figures 1-5 and Figures 9-11 As shown, the slag removal unit 31 includes a first rotating shaft 311 rotatably disposed inside the temporary storage cavity 14, several sets of slag removal frames 312 disposed on the first rotating shaft 311 and fitting against the inner wall of the temporary storage cavity 14, a sealing box 313 disposed on the back of the slag removal frames 312, several sets of leakage holes formed on the slag removal frames 312 and communicating with the inside of the sealing box 313, a push plate 314 slidably disposed inside the sealing box 313, and a slag removal unit 314 disposed on the side of the push plate 314 and the inner wall of the sealing box 313. The components include: a first elastic element 315; a sponge 316 disposed between the side of the push plate 314 and the inner wall of the sealing box 313; an insertion hole 317 opened on the side wall of the sealing box 313; a protrusion disposed on the side of the push plate 314 and used to block the insertion hole 317; a drain hole 318 opened on the other side wall of the sealing box 313; a one-way valve disposed at the drain hole 318; and a sealing plate 319 disposed inside the annular channel 12 and located between the temporary storage chamber 14 and the inlet pipe 15. The slag discharge unit 32 includes a first window 321 on the side of the filter box 11, a slag collection box 322 disposed at the first window 321, a liquid collection box 323 disposed at the first window 321 and located on one side of the slag collection box 322, a second window 324 on the other side of the filter box 11, several sets of rotating plates 325 disposed on the first rotating shaft 311 and located outside the filter box 11, a limiting hole disposed on the rotating plate 325, a blocking plate 326 slidably disposed on the limiting hole via a limiting block and used to block the leakage hole, a scraper 327 disposed on the blocking plate 326 and used to clean the scooping frame 312, a hydraulic component 328 disposed on the rotating plate 325, a linkage plate 329 disposed on the output shaft of the hydraulic component 328, a second elastic component 3291 disposed between the side of the linkage plate 329 and the blocking plate 326, and a plug rod 3292 disposed on the linkage plate 329 and cooperating with the plug hole 317.

[0043] It is worth mentioning that the function of the sealing plate 319 is to prevent the liquid and filter residue in the temporary storage chamber 14 from flowing back into the annular channel 12. If the liquid in the temporary storage chamber 14 flows back and rises to the position of the inlet pipe 15, it will hinder the flow of the liquid newly flowing into the annular channel 12 from the inlet pipe 15, resulting in a decrease in the flow rate of the liquid newly flowing into the annular channel 12, causing the decelerated liquid to be insufficient to rise and flow along the annular channel 12. It should be noted that the fourth rotating shaft 47 and the first rotating shaft 311 rotate in opposite directions through the transmission of pulleys and belts. That is, the first rotating shaft 311 and the second rotating shaft 212 rotate in the same direction, while the second rotating shaft 212 is opposite to the flow direction of the liquid in the annular channel 12. Thus, the rotation direction of the first rotating shaft 311 is opposite to the flow direction of the liquid in the annular channel 12, which makes it easier for the scooping frame 312 to better scoop out the filter residue in the liquid. It should also be noted that the blocking plate 326 can block the leakage hole of the scoop frame 312, preventing the liquid squeezed out by the sponge 316 from flowing out of the leakage hole.

[0044] In this embodiment, the slag removal unit 31 and the slag discharge unit 32 work together to automatically remove the filter residue in the temporary storage chamber 14 and scrape it off for unified collection, ensuring the continuity of the slag removal work. On the other hand, they can filter and discharge the liquid in the temporary storage chamber 14, preventing excess liquid from accumulating in the temporary storage chamber 14 and ensuring that all the liquid flowing from the liquid inlet pipe 15 into the annular channel 12 is quickly filtered out so that it can be supplied to the machine tool for recycling.

[0045] In detail, the accelerated excess liquid impacts the bottom of the annular channel 12 in stages, agitating the filter residue accumulated at the bottom of the annular channel 12 and causing it to rise into the temporary storage chamber 14. Then, the fourth rotating shaft 47 drives the first rotating shaft 311 to rotate in the opposite direction through a pulley and belt drive, so that the rotation direction of the first rotating shaft 311 is opposite to the flow direction of the liquid in the annular channel 12. This causes the first rotating shaft 311 to drive the scooping frame 312 to scoop out the filter residue from the liquid in the temporary storage chamber 14. The liquid filtered from the leakage hole of the scooping frame 312 enters the sealing box 313, and the filtered liquid is absorbed by the sponge 316. When the scooping frame 312 rotates upward to the position of the first window 321, the hydraulic component 328 drives the linkage plate 329 and the second elastic component 3291 to move the blocking plate 326 toward the scooping frame 312, so that the scraper 327 on the blocking plate 326 pushes the filter residue on the scooping frame 312 into the slag collection box 322. At the same time, The blocking plate 326 also blocks the leakage hole of the scooping frame 312. When the sealing box 313 rotates to the position of the liquid receiving box 323, the hydraulic component 328 continues to drive the linkage plate 329 to move towards the scooping frame 312. The linkage plate 329 compresses the second elastic element 3291, causing the insertion rod 3292 on the linkage plate 329 to enter the sealing box 313 through the insertion hole 317. This causes the insertion rod 3292 to drive the push plate 314 to squeeze the sponge 316, and the liquid squeezed out of the sponge 316 flows out from... The liquid flows into the liquid collection box 323 through the drain hole 318. When the sealing box 313 is removed from the position of the liquid collection box 323, the hydraulic component 328 drives the linkage plate 329, the second elastic component 3291, the blocking plate 326, and the insertion rod 3292 to reset. This causes the push plate 314 inside the sealing box 313 to reset with the sponge 316 under the elastic force of the first elastic component 315. The protrusion on the push plate 314 then blocks the insertion hole 317 of the sealing box 313 again, making it convenient to use for slag removal again.

[0046] Furthermore, such as Figures 1-2 and Figure 7 As shown, the liquid outlet unit 16 includes two sets of liquid outlet boxes 161 disposed on the outer wall of the filter box 11, a liquid outlet pipe 162 opened at the bottom of the liquid outlet box 161, a water pump 163 disposed on the liquid outlet pipe 162, and a liquid transfer pipe 164 disposed at the bottom of the liquid collection box 323 and connected to the liquid outlet pipe 162.

[0047] In this embodiment, the liquid outlet unit 16 can accelerate the flow of the filtered liquid, prevent the filtered liquid from accumulating in the liquid outlet box 161, and speed up the recycling of the liquid.

[0048] In detail, the liquid filtered from the arc-shaped filter plate 13 enters the liquid outlet box 161. The water pump 163 draws the liquid in the liquid outlet box 161 into the liquid outlet pipe 162. The liquid in the liquid collection box 323 also flows into the liquid outlet pipe 162 through the liquid transfer pipe 164. The combined liquid flows from the liquid outlet pipe 162 into the machine tool's coolant circulation system.

[0049] Example 2 like Figure 12 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows: Furthermore, such as Figure 12 As shown, a check valve is provided on the transfer pipe 164 to ensure that the liquid in the liquid collection box 323 can flow through the transfer pipe 164 to the liquid outlet pipe 162, but the liquid in the liquid outlet pipe 162 will not flow back into the liquid collection box 323.

[0050] Work process: First, the liquid flows into the annular channel 12 from the inlet pipe 15 and passes through two sets of arc-shaped filter plates 13 in sequence. After being filtered by the arc-shaped filter plates 13, part of the liquid is discharged from the outlet unit 16. The other part of the liquid that is not discharged in time continues to flow along the annular channel 12 to the position of the dust collection component 2. The liquid that subsequently flows into the annular channel 12 washes the arc-shaped filter plates 13 and carries the filter residue to the position of the dust collection component 2. The dust collection component 2 cleans and discharges the metal shavings in the liquid, and at the same time accelerates the excess liquid that is not discharged in time. The accelerated excess liquid impacts the bottom of the annular channel 12 in segments, agitating the filter residue accumulated at the bottom of the annular channel 12 and raising it to the temporary storage chamber 14. The residue collection unit 31 collects the filter residue and adsorbs and transfers the excess liquid in the temporary storage chamber 14.
