Description

Technical Field

[0001] The invention relates to the technical field of chip liquid filtering, and in particular to a chip liquid filtering device with a spiral flow-guiding rotating hollow cylinder. Background Art

[0002] Metal processing is the process of processing metal materials into products of desired shape, size and performance through various techniques, covering the whole process from rough processing to finishing. The metal processing techniques include cold processing and hot processing, and cutting fluid is used during metal processing.

[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 to provide the necessary lubrication and cooling protection for the machine tool cutting process. It also helps to extend the tool life and improve the processing quality. It has good lubricity and cooling properties 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, the cutting fluid is often mixed with the iron chips generated after processing, which will have a series of effects on the performance and reuse of the cutting fluid. Therefore, the cutting fluid needs to be filtered, and the cutting fluid is separated into solid and liquid through a drum screen to separate the iron chips mixed in the cutting fluid so that the cutting fluid can be reused.

[0005] The drum screen is a device that uses a rotating drum and a screen to separate materials. When the cutting fluid containing iron chips passes through the drum screen, the iron chips and other solid impurities will be retained by the screen, while the cutting fluid flows 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 carrying container for storage, and after the metal processing is completed, the large amount of collected cutting fluid will be poured into the inside of the drum screen for filtration, and a spiral is installed inside the drum screen to guide the cutting fluid inside the drum screen, so that the cutting fluid containing iron chips can be evenly filtered inside the drum screen, but the rotating motion of the drum screen causes the cutting fluid and iron chips to roll continuously in the screen. In 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 attached to the screen, causing the screen to be blocked, thereby reducing the filtering performance of the drum screen for the cutting fluid. Summary of the invention

[0007] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a spiral guide rotating hollow cylinder chip liquid filtering equipment to solve the problem that the rotation movement of the above-mentioned drum screen causes iron chips to get stuck around the screen holes and then adhere to the screen, causing the screen to be blocked, thereby reducing the filtering performance of the drum screen for the chip liquid.

[0059] refer to Figure 3 , Figure 5 , Figure 6 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, a vibration assembly 30 is provided on the connecting tube 25 for impacting the inner wall of the filter element 1103 , thereby reducing the adhesion of iron filings on the mesh of the filter element 1103 .

[0060] The vibration assembly 30 includes a plurality of sliding plates 31 arranged at equal distances, and the plurality of sliding plates 31 are arranged in a ring shape on the surface of the thin section of the connecting tube 25. The interior of each scraper block 28 corresponds to a sliding plate 31, and the side walls of each sliding plate 31 are slidably connected to the inner wall of the corresponding scraper block 28 for impacting the surface of the filter element 1103. A fixed plate 32 is fixed to the inner wall of each scraper block 28, and each fixed plate 32 corresponds to a sliding plate 31. A plurality of first reset springs 33 arranged at equal distances are fixed between the sliding plate 31 and the fixed plate 32 for supporting the sliding plate 31, thereby facilitating the reset of the sliding plate 31.

[0061] Each scraper block 28 is provided with a plurality of U-shaped plates 34 arranged at equal distances inside, and a plurality of sliding openings 310 arranged at equal distances and adapted to the U-shaped plates 34 are opened on the fixed plate 32. 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, and a plurality of U-shaped plates 34 arranged circumferentially of the connecting tube 25 are grouped together.

[0062] A fixed shaft 35 is provided inside each of the two connecting cylinders 25, a limiting hole 36 is opened 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 mouth 1101, and the other end of the fixed shaft 35 is fixed to a side wall of the connecting block 24, and a plurality of first connecting plates 37 arranged at equal distances are fixed on the surface of the fixed shaft 35, and each first connecting plate 37 corresponds to a group of U-shaped plates 34 arranged circumferentially of the connecting cylinder 25.

[0063] Each first connecting plate 37 is provided with a slide rail 38, which consists of an arc segment and a transverse segment. The head end of the arc segment is connected to the head end of the transverse segment, and the tail end of the arc segment is connected to the tail end of the transverse segment.

[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 to the inside of the corresponding sliding rail 38 .

[0065] When the driving shaft 16 is in a rotating state, the driving shaft 16 drives the guide member 17 to rotate counterclockwise. Since the linkage inner gear ring 210 and the second outer gear ring 29 are in a meshing state, the second outer gear ring 29 drives the thin section of the connecting tube 25 to rotate clockwise inside the second through hole 26, and the thick section of the connecting tube 25 rotates on the connecting block 24, and the connecting tube 25 drives the scraper block 28 on its surface to scrape the inner wall surface of the filter element 1103 in turn. As the connecting tube 25 rotates, when the sliding shaft 39 slides to the head end of the arc segment, the sliding shaft 39 drives the U-shaped plate 34 to slide inside the corresponding sliding mouth 310. At this time, the U-shaped plate 34 slides toward the fixed shaft 35, and at the same time compresses the first return spring 33, and the U-shaped plate 34 drives the connected sliding plate 31 to slide inside the scraper block 28.

When the sliding shaft 39 slides to the tail end of the transverse segment, the sliding plate 31 hits 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 tube 25 rotates, the sliding shaft 39 at the tail end of the transverse segment slides to the tail end of the arc segment, and slides from the tail end of the arc segment to its head section again, and repeats the above operation.

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

The plurality of push plates 41 are arranged in a ring shape on the thin section of the connecting tube 25. There is a push plate 41 between every two scraper blocks 28, and the outer walls on both sides of the push plate 41 are respectively slidably connected to the side walls of adjacent scraper blocks 28. Brushes 42 are installed on the push plate 41 for cleaning the inner wall surface of the filter element 1103.

[0070] A plurality of equidistantly arranged receiving grooves 43 matching the push plate 41 are provided on the step surface of the connecting tube 25. The plurality of receiving grooves 43 are arranged in a ring shape on the step surface of the connecting tube 25, and each receiving groove 43 corresponds to a push plate 41. The push plate 41 is slidably connected to the inside of the corresponding receiving groove 43. A second reset spring 47 is fixed between the inner wall of the receiving groove 43 and one side of the push plate 41 for supporting the push plate 41, thereby facilitating the reset of the push plate 41.

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

[0072] When the connecting tube 25 is in a rotating state, the bristles 42 on the push plate 41 can clean the inner wall surface of the filter element 1103, and when the linkage shaft 44 of the push plate 41 contacts the linkage block 46, the linkage shaft 44 is squeezed by the linkage block 46, and the linkage shaft 44 drives the push plate 41 to slide between two adjacent scraper blocks 28. At the same time, the push plate 41 slides toward the inside of the accommodating groove 43, and the push plate 41 compresses the second return spring 47, and the push plate 41 drives the bristles 42 to slide along the axial direction of the filter tube 11, thereby cleaning the inner wall of the filter element 1103.

[0073] When the linkage shaft 44 is disengaged from the linkage block 46, the second reset spring 47 is disengaged from the extrusion for reset, and the second reset spring 47 drives the push plate 41 to reset, and the bristles 42 on the push plate 41 clean the inner wall surface of the filter element 1103 again, thereby maintaining the filtering performance of the filter element 1103 for the chip liquid.

[0074] By rotating the connecting cylinder 25, the bristles 42 on the push plate 41 clean the dirt clogging the mesh of the filter element 1103, and the contact between the linkage shaft 44 and the linkage block 46 can drive the push plate 41 to slide laterally between two adjacent scraper blocks 28, thereby changing the cleaning angle of the bristles 42, thereby improving the cleaning performance of the filter element 1103.
