Description

Technical Field

[0001] The present invention relates to the technical field of chip fluid filtration, and more particularly to a chip fluid filtration device with a spiral guide rotating hollow cylinder. Background Art

[0002] Metal processing is the process of machining metal materials into products with the required shape, size, and performance through various processes, covering the entire process from rough machining to finish machining. The processes of metal processing include cold working and hot working, and when metal is processed, chip fluid is used.

[0003] Cutting fluid is a liquid that plays a role in cooling, lubricating, and cleaning during the metal processing process. It is widely used in the metal processing industry, providing necessary lubrication and cooling protection for the machine tool cutting process. At the same time, it helps to extend the tool life and improve the processing quality, has good lubricity and cooling performance, and can effectively reduce friction and heat accumulation during cutting.

[0004] During the metal processing process, cutting fluid is used to flush and cool the processing area, and then it will be collected for reuse. However, during the collection process, cutting fluid often mixes with the iron chips generated after processing, which will have a series of impacts on the performance and reuse of cutting fluid. Therefore, it is necessary to filter the chip fluid, and the chip fluid is separated from solid and liquid through a drum screen to separate the iron chips mixed in the chip fluid for the convenience of reusing the chip fluid.

[0005] A drum screen is a device that separates materials by using a rotating drum and a screen. When the cutting fluid containing iron chips passes through the drum screen, solid impurities such as iron chips will be intercepted by the screen, and the cutting fluid will flow out through the screen, thus achieving solid-liquid separation.

[0006] Since the cutting fluid used in the metal processing process will be collected in a bearing container for storage, and after the metal processing is completed, a large amount of collected cutting fluid will be poured into the inside of the drum screen for filtration. And a spiral part is installed inside the drum screen to guide the cutting fluid inside the drum screen, so that the cutting fluid containing iron chips is evenly filtered inside the drum screen. However, the rotational movement of the drum screen causes the cutting fluid and iron chips to continuously tumble inside the screen. During this process, the iron chips may be squeezed onto the surface of the screen, and the screen hole structure of the screen will hinder the movement of the iron chips. When the iron chips try to pass through the screen holes but cannot pass through, they may be stuck around the screen holes and then adhere to the screen, causing blockage of the screen, thereby reducing the filtration performance of the drum screen for the chip fluid. Summary of the Invention

[0007] In view of the above situation, to overcome the defects of the prior art, the present invention provides a spiral diversion rotary hollow cylinder chip liquid filtering device to solve the problem that the rotary motion of the drum sieve causes iron chips to get stuck around the sieve holes, and then adhere to the sieve mesh, resulting in the blockage of the sieve mesh, thereby reducing the filtering performance of the drum sieve for chip liquid.

[0045] As shown in the attached Figures 1 - 4 figure, a spiral deflector rotating hollow cylinder chip liquid filtering device includes:

[0046] Frame 10, with a filter cartridge 11 installed inside it, which is used to filter out impurities in the cutting fluid.

[0047] The filter cartridge 11 includes two barrel openings 1101, and both of the two barrel openings 1101 are concave. The two barrel openings 1101 respectively correspond to the inlet end and the outlet end of the filter cartridge 11. Both of the two barrel openings 1101 are fixed on the frame 10. A middle ring 1102 is arranged between the two barrel openings 1101. Filtering elements 1103 are fixed on both sides of the middle ring 1102. And the sides of the two filtering elements 1103 away from the middle ring 1102 are respectively rotatably connected to the side walls of the corresponding barrel openings 1101. A discharge port 1104 is opened at the bottom of the barrel opening 1101 at the outlet end of the filter cartridge 11, which is used to discharge the filtered residues.

[0048] On one side of the barrel opening 1101 at the inlet end of the filter cartridge 11, there is a feed hopper 12, and the feed hopper 12 is installed on the frame 10. The barrel opening 1101 at the inlet end of the feed hopper 12 extends into the interior of the filter cartridge 11. A first driving source 13 is installed on the top of the frame 10. A linkage gear 14 is installed at the output end of the first driving source 13. A first external gear ring 15 is installed outside the middle ring 1102, and the first external gear ring 15 is meshed with the linkage gear 14.

[0049] A driving shaft 16 is arranged in the middle of the filter cartridge 11. A flow guiding element 17 is fixed to the outer wall of the driving shaft 16 through a connecting arm. In this embodiment, the flow guiding element 17 is spiral. The flow guiding element 17 is used to guide the cutting fluid inside the filter cartridge 11. Support elements 18 are installed on the inner walls of both barrel openings 1101.

[0050] Both of the two support elements 18 are triangular, and both of the two support elements 18 have circular holes in the middle. And the outer walls of both ends of the driving shaft 16 are respectively rotatably connected to the inner walls of the corresponding circular holes. A second driving source 19 is installed at the bottom of the frame 10 at the inlet end of the filter cartridge 11, and the output end of the second driving source 19 is fixed to one end of the driving shaft 16.

[0051] A material receiving box 110 and a liquid receiving box 111 are installed on the inner bottom wall of the frame 10. And the material receiving box 110 is located below the discharge port 1104, and the liquid receiving box 111 is located below the filter cartridge 11.

[0052] During use, pour the cutting fluid containing iron filings into the interior of the feed hopper 12. The cutting fluid flows along the liquid outlet end of the feed hopper 12 into the interior of the filter cylinder 11. The output end of the first driving source 13 drives the middle ring 1102 to rotate through the meshing connection of the linkage gear 14 and the first external tooth ring 15. The middle ring 1102 drives the two connected filter elements 1103 to rotate. The cutting fluid containing iron filings flows inside the filter cylinder 11, and the iron filings in the cutting fluid are filtered out by the filter elements 1103. The output end of the second driving source 19 drives the flow guiding member 17 to rotate through the driving shaft 16. The rotation direction of the flow guiding member 17 is opposite to that of the middle ring 1102. The flow guiding member 17 guides the cutting fluid inside the filter cylinder 11 to flow. The liquid filtered out by the filter elements 1103 flows into the interior of the liquid receiving box 111 for collection. When the impurities filtered inside the filter cylinder 11 are pushed by the flow guiding member 17 to the barrel opening 1101 at the outlet end of the filter cylinder 11, they are discharged from the discharge port 1104 and fall into the interior of the material receiving box 110 for collection.

[0054] A scraping assembly 20 is provided on the flow guiding member 17 for scraping the dirt attached to the inner wall of the filter element 1103, so as to maintain the filtering performance of the filter element 1103 for the cutting fluid.

[0055] The scraping assembly 20 includes end blocks 21 fixed at both the head and tail ends of the flow guiding member 17, and the two end blocks 21 are symmetric about the middle ring 1102. A first through hole 23 is formed in the middle of the flow guiding member 17, and a connecting block 24 is fixed to the inner wall of the first through hole 23. In this embodiment, the connecting block 24 is circular, and connecting cylinders 25 are connected to both sides of the connecting block 24.

[0056] Second through holes 26 are formed in both of the two end blocks 21, and the axis of the second through hole 26 and the axis of the first through hole 23 are in the same horizontal plane. The outer wall of the thin section of the connecting cylinder 25 is rotatably connected to the inner wall of the corresponding second through hole 26. The diameter value of the second through hole 26 is greater than the diameter value of the thin section of the connecting cylinder 25. A plurality of openings 27 arranged at equal intervals are formed in the outer wall of the thin section of the connecting cylinder 25. The plurality of openings 27 are arranged in a ring on the outer wall of the thin section of the connecting cylinder 25. A scraping block 28 is fixed to the inner wall of each opening 27, and the scraping block 28 is in a shape of a double-square frame. There is a gap between every two of the plurality of scraping blocks 28.

[0057] On the outer walls of the ends of the two thin sections of the connecting cylinder 25 extending out of the corresponding second through holes 26, a second external tooth ring 29 and a sealing plate 211 are fixed respectively. On the inner walls of the two cylinder openings 1101, a linkage internal tooth ring 210 is fixed respectively. The two second external tooth rings 29 are respectively meshed and connected with the corresponding linkage internal tooth rings 210 to drive the connecting cylinder 25 to rotate, so that the scraping block 28 cleans the inner wall of the filter element 1103.

[0058] The sealing plate 211 is located between the corresponding connecting block 24 and the second external tooth ring 29. The outer walls of the two sealing plates 211 are respectively rotatably connected to the inner walls of the corresponding cylinder openings 1101. The two sealing plates 211 respectively define an accommodation gap with the inner side walls of the corresponding cylinder openings 1101. The linkage internal tooth ring 210 and the second external tooth ring 29 are both located inside the accommodation gap. Communication holes 212 adapted to the thin section of the connecting cylinder 25 are formed in both of the two sealing plates 211. The outer wall of the thin section of the connecting cylinder 25 is rotatably connected to the inner wall of the communication hole 212.

[0060] A vibration assembly 30 is arranged on the connecting cylinder 25 to impact the inner wall of the filter element 1103, so as to reduce the adhesion of iron filings on the mesh holes of the filter element 1103. The vibration assembly 30 includes a plurality of sliding plates 31 arranged at equal intervals. The plurality of sliding plates 31 are arranged in a ring on the surface of the thin section of the connecting cylinder 25. One sliding plate 31 corresponds to each scraping block 28. The side wall of each sliding plate 31 is slidably connected to the inner wall of the corresponding scraping block 28 to impact the surface of the filter element 1103. A fixing plate 32 is fixed to the inner wall of each scraping block 28. One fixing plate 32 corresponds to each sliding plate 31. A plurality of first return springs 33 arranged at equal intervals are fixed between the sliding plate 31 and the fixing plate 32 to support the sliding plate 31, so as to facilitate the reset of the sliding plate 31.

[0061] Inside each scraping block 28, a plurality of U-shaped plates 34 arranged at equal distances are provided. On the fixing plate 32, a plurality of sliding openings 310 arranged at equal distances and adapted to the U-shaped plates 34 are formed. Each sliding opening 310 corresponds to a U-shaped plate 34, and the U-shaped plate 34 is slidably connected inside the corresponding sliding opening 310. A group is formed by the plurality of U-shaped plates 34 arranged circumferentially around the connecting cylinder 25.

[0062] Inside both of the two connecting cylinders 25, a fixed shaft 35 is provided. A limiting hole 36 is formed in the middle of the thick section of the connecting cylinder 25, and the outer wall of the fixed shaft 35 is rotatably connected to the inner wall of the corresponding limiting hole 36. One end of the fixed shaft 35 extending out of the connecting cylinder 25 is slidably connected to the inner wall of the corresponding cylinder opening 1101. The other end of the fixed shaft 35 is fixed to one side wall of the connecting block 24. A plurality of first connecting disks 37 arranged at equal distances are fixed on the surface of the fixed shaft 35. Each first connecting disk 37 corresponds to a group of U-shaped plates 34 arranged circumferentially around the connecting cylinder 25.

[0063] On each first connecting disk 37, a slide rail 38 is formed. The slide rail 38 is composed of an arc section and a horizontal section. The head end of the arc section is communicated with the head end of the horizontal section, and the tail end of the arc section is communicated with the tail end of the horizontal section. The head end of the arc section is close to the center of the first connecting disk 37, and the tail end of the arc section is far from the center of the first connecting disk 37.

[0064] A sliding shaft 39 is fixed to the inner wall of the U-shaped plate 34, and the sliding shaft 39 is slidably connected inside the corresponding slide rail 38.

[0065] When the drive shaft 16 is in a rotating state, the drive shaft 16 drives the flow guiding member 17 to rotate counterclockwise. Since the linkage internal gear ring 210 and the second external gear ring 29 are in a meshing state, the second external gear ring 29 drives the thin section of the connecting cylinder 25 to rotate clockwise inside the second through hole 26, and the thick section of the connecting cylinder 25 rotates on the connecting block 24. The connecting cylinder 25 drives the scraping blocks 28 on its surface to sequentially scrape the inner wall surface of the filter element 1103. As the connecting cylinder 25 rotates, when the sliding shaft 39 slides to the head end of the arc section, the sliding shaft 39 drives the U-shaped plate 34 to slide inside the corresponding sliding opening 310. At this time, the U-shaped plate 34 slides towards the fixed shaft 35, and simultaneously compresses the first return spring 33. The U-shaped plate 34 drives the connected sliding plate 31 to slide inside the scraping block 28.

[0066] After the sliding shaft 39 slides from the head end of the arc segment to the head end of the horizontal segment, the sliding shaft 39 is not restricted at this time, and the first return spring 33 is reset. Then the sliding shaft 39 slides from the head end of the horizontal segment to its tail end, and the first return spring 33 drives the sliding plate 31 to slide towards the outer direction of the scraping block 28. When the sliding shaft 39 slides to the tail end of the horizontal segment, the sliding plate 31 impacts the inner wall surface of the filter element 1103, thereby vibrating and dropping the iron filings attached to the inner wall surface of the filter element 1103. As the connecting cylinder 25 rotates, the sliding shaft 39 at the tail end of the horizontal segment slides towards the tail end of the arc segment and then slides from the tail end of the arc segment to its head segment again, repeating the above operation.

[0067] By sliding the sliding shaft 39 along the track of the slide rail 38, the sliding plate 31 can be driven to slide inside the scraping block 28. When the sliding plate 31 is reset, it will impact the filter element 1103, thereby causing vibration in the corresponding area between the inner wall of the filter element 1103 and the sliding plate 31, thus reducing the adhesion of dirt on the filter element 1103.

[0069] A cleaning assembly 40 is provided on the connecting cylinder 25 for cleaning the iron filings that clog the mesh holes of the filter element 1103 and maintaining the filtering performance of the filter element 1103.

[0070] The cleaning assembly 40 includes a plurality of push plates 41 arranged at equal distances on the surface of the thin section of the connecting cylinder 25. The plurality of push plates 41 are arranged in a ring on the thin section of the connecting cylinder 25. There is one push plate 41 between every two scraping blocks 28, and the outer walls on both sides of the push plate 41 are respectively slidably connected to the side walls of the adjacent scraping blocks 28. A brush 42 is installed on the push plate 41 for cleaning the inner wall surface of the filter element 1103.

[0071] A linkage shaft 44 is fixed to one side of each push plate 41 away from the connecting block 24. Second connecting discs 45 are fixed to the sides of the two end blocks 21 facing the connecting block 24. A plurality of linkage blocks 46 arranged at equal distances are fixed to the side of the second connecting disc 45 facing the connecting cylinder 25. The plurality of linkage blocks 46 are arranged in a ring on one side of the connecting cylinder 25.

[0072] When the connecting cylinder 25 is in a rotating state, the bristles 42 on the pushing plate 41 can clean the inner wall surface of the filter element 1103. When the linkage shaft 44 of the pushing plate 41 contacts the linkage block 46, the linkage shaft 44 is squeezed by the linkage block 46. The linkage shaft 44 drives the pushing plate 41 to slide between two adjacent scraping blocks 28. At the same time, the pushing plate 41 slides into the inner part of the receiving groove 43, and the pushing plate 41 compresses the second return spring 47. The pushing plate 41 drives the bristles 42 to slide along the axial direction of the filter cylinder 11, so as to clean the inner wall of the filter element 1103.

[0073] After the linkage shaft 44 disengages from the linkage block 46, the second return spring 47 is released from extrusion and resets. The second return spring 47 drives the pushing plate 41 to reset, and the bristles 42 on the pushing plate 41 clean the inner wall surface of the filter element 1103 again, so as to maintain the filtering performance of the filter element 1103 for the cutting fluid.

[0074] By rotating the connecting cylinder 25, the bristles 42 on the pushing plate 41 clean the dirt blocked in the mesh holes of the filter element 1103. The contact between the linkage shaft 44 and the linkage block 46 can drive the pushing plate 41 to slide horizontally between two adjacent scraping blocks 28, so as to change the cleaning angle of the bristles 42, thereby improving the cleaning performance of the filter element 1103.
