Description

Technical Field

[0001] This utility model relates to the field of cutting fluid filtration equipment, and in particular to a cutting fluid flocculent filtration device for ultrathin silicon single crystal diamond wire cutting. Background Technology

[0002] Ultrathin silicon single crystal diamond wire slicing is a technology used to process silicon single crystal ingots into ultrathin silicon wafers. It has wide applications in the solar photovoltaic industry and semiconductor manufacturing. Utilizing the high-speed movement of diamond wires, the silicon single crystal ingot is sliced ​​into thin wafers through physical cutting. During the cutting process, the diamond wires rotate cyclically under the drive of guide rollers, while the silicon single crystal ingot is fixed on a worktable. As the worktable feeds, the diamond wires contact and cut the silicon single crystal ingot. During cutting, the diamond powder on the diamond wires acts as a cutting force, gradually cutting off the silicon single crystal material to form a silicon wafer of the required thickness.

[0003] During the cutting process, flocculent matter and impurities of different particle sizes coexist in the cutting fluid. A single filtration method is insufficient to completely remove both large particles and fine flocculent matter simultaneously. Large particles may scratch the silicon wafer surface, while fine flocculent matter can affect the cutting fluid's performance, leading to a decline in wafer quality. This necessitates frequent replacement of filter elements, increasing equipment operating costs and maintenance workload, and impacting production continuity and stability. During filtration, flocculent matter and impurities in the cutting fluid continuously adhere to the filter element surface. If these impurities cannot be removed promptly, they gradually accumulate on the filter element surface, forming a thick filter cake. This reduces the size of the filtration channels, increases filtration resistance, and extends equipment downtime, affecting production schedules and increasing equipment maintenance and labor costs.

[0004] The main objective of this invention is to provide a cutting fluid flocculent filtration device for ultrathin silicon single crystal diamond wire cutting, which can effectively solve the problems of declining slice quality, the need for frequent replacement of filter elements, increased equipment operating costs and maintenance workload, impact on production continuity and stability, smaller filter channels, increased filtration resistance, increased equipment downtime, impact on production progress, and increased equipment maintenance and labor costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cutting fluid flocculent filtration device for ultrathin silicon single crystal diamond wire slicing, comprising a cylindrical body, a feed pipe being connected through the top left side of the cylindrical body, a sliding groove being provided on the left side of the feed pipe, an installation groove being provided on the inner wall of the feed pipe, the right sides of the four sliding grooves communicating with the installation groove, a first limiting block being fixedly connected inside the installation groove, a fixing ring being provided inside the feed pipe, a coarse filter plate being fixedly connected inside the fixing ring, a first slider being fixedly connected to the outer side of the fixing ring, the four first sliders being correspondingly arranged with the installation groove and the four sliding grooves, and a drain hole being provided at the bottom of the feed pipe, the drain hole being located at the bottom left side of the coarse filter plate.

[0006] Furthermore, a filter cylinder is provided inside the cylinder body, and support rings are fixedly connected to the outer sides of both the upper and lower ends of the filter cylinder. The two support rings are fixedly connected to the top and middle of the cylinder body. The feed pipe is located on the top of the top support ring, and a baffle is provided inside the bottom end of the filter cylinder.

[0007] Furthermore, the baffle is fixedly connected to the inside of the left and right sides, and the outer sides of the two first connecting rods pass through the inside of the bottom support ring and are rotatably connected to the inside of the cylinder. The other end of the first connecting rod on the left side is fixedly connected to a handle, which is located at the bottom left side of the cylinder.

[0008] Furthermore, a sludge storage hopper is fixedly connected to the bottom of the cylinder, a sludge discharge pipe is connected through the bottom of the sludge storage hopper, and a support leg is fixedly connected to the bottom of each sludge storage hopper.

[0009] Furthermore, a discharge pipe is connected through the bottom of the right side wall of the cylinder, a control valve is provided on the outside of the discharge pipe, and the left end of the discharge pipe is located on the top right side of the bottom support ring.

[0010] Furthermore, a protective box is fixedly connected to the top of the cylinder, and a motor is installed inside the protective box. A rotating rod is fixedly connected to the output end of the motor. A second connecting rod is fixedly connected to the outer side of the top end of the rotating rod. Four connecting columns are fixedly connected to both the left and right sides of the second connecting rod, and a guide rail plate is fixedly connected to the other end of each connecting column.

[0011] Furthermore, a second limiting block is fixedly connected to the bottom wall of each guide rail plate, two second sliders are slidably connected inside each guide rail plate, a support plate is fixedly connected to the other side of each pair of second sliders, a scraper is fixedly connected to the outer wall of each support plate, and the outer walls of the four scrapers are correspondingly arranged with the inside of the filter cylinder.

[0012] Furthermore, a sleeve is fixedly connected to the outer side of the bottom end of the rotating rod, and a connecting block is fixedly connected to the bottom wall of the sleeve. A stirring paddle is threadedly connected to the middle of the two connecting blocks.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model, through its feed pipe, mounting groove, coarse filter plate, baffle, connecting rod, filter cylinder, and support ring, solves the problems that lead to decreased slice quality, require frequent replacement of filter elements, increase equipment operating costs and maintenance workload, and affect the continuity and stability of production. It is connected to the cylinder body via first connecting rods on both the left and right sides. During normal filtration, the baffle remains closed, sealing the bottom of the filter cylinder and effectively preventing the liquid being filtered from flowing to the bottom without sufficient filtration, ensuring that the cutting fluid completes the fine filtration process within the filter cylinder. When cleaning the filter cylinder is required, turning the handle rotates the first connecting rod on the left, causing the baffle to rotate and open around the first connecting rod. Impurities trapped inside the filter cylinder fall into the storage hopper below under gravity for temporary storage, effectively reducing downtime caused by cutting fluid supply issues, improving production efficiency, reducing equipment maintenance costs and repair frequency, and extending the equipment's service life.

By incorporating a motor, rotating rod, guide rail, second slider, scraper, connecting block, and stirring paddle, the system effectively addresses the problems of reduced filtration channel size, increased filtration resistance, longer equipment downtime, impacted production schedules, and increased maintenance and labor costs. The sleeve at the bottom of the rotating rod, the connecting block, and the stirring paddle all rotate with the rotating rod. The stirring paddle agitates the cutting fluid within the filter cartridge, ensuring that flocculent matter is more evenly dispersed in the liquid, preventing sedimentation and accumulation. This facilitates the filter cartridge's interception and filtration of flocculent matter, effectively ensuring the cutting fluid passes through the filtration device efficiently, effectively trapping fine flocculent matter and impurities, and improving the cleanliness of the filtered cutting fluid.

[0031] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0032] like Figure 1 - Figure 5 The following describes a cutting fluid flocculent filtration device for ultrathin silicon single crystal diamond wire slicing, comprising a cylindrical body 1. A feed pipe 2 is connected to the top left side of the cylindrical body 1, connecting to an external pipeline to deliver used cutting fluid into the cylindrical body 1 for processing. The feed pipe 2 has four grooves 3 on its left side and four mounting grooves 4 on its inner wall. The right sides of the four grooves 3 communicate with the mounting grooves 4. A first limiting block 5 is fixedly connected inside each mounting groove 4. A fixing ring 6 is installed inside the feed pipe 2, and a coarse filter plate 7 is fixedly connected inside the fixing ring 6. First sliders 8 are fixedly connected to the outside of the fixing ring 6, with the four first sliders 8 corresponding to the inside of the mounting grooves 4 and the four grooves 3. A drain hole 9 is located at the bottom left of the coarse filter plate 7, which is fixed to the outside by the fixing rings 6. During installation, the outside of the fixing ring 6 is... Align the four first sliders 8 with the four slide grooves 3, and place the fixing ring 6 inside the slide groove 3. At the same time, push the fixing ring 6 and the coarse filter plate 7 into the feed pipe 2 again, so that the first sliders 8 enter the installation groove 4. At this time, rotate the fixing ring 6 so that the first slider 8 fits with the first limiting block 5 inside the installation groove 4, and fix the fixing ring 6 and the coarse filter plate 7 inside the feed pipe 2 to perform preliminary filtration of the cutting fluid entering the cylinder 1, and separate larger impurities and particles in the cutting fluid. The separated impurities and particles will be discharged into the feed pipe 2 through the drain hole 9 opened at the bottom of the feed pipe 2.

[0033] When it is necessary to disassemble and replace the fixing ring 6 and the coarse filter plate 7, rotate the fixing ring 6 so that the first slider 8 on the outside of the fixing ring 6 is aligned with the corresponding positions of the mounting groove 4 and the four sliding grooves 3. Pull the first slider 8 out of the inside of the sliding groove 3, and the fixing ring 6 and the coarse filter plate 7 can be disassembled and replaced.

[0034] like Figure 1 - Figure 8 As shown, a filter cylinder 18 is installed inside the cylinder body 1. Support rings 19 are fixedly connected to the outer sides of both the upper and lower ends of the filter cylinder 18. The two support rings 19 are fixedly connected to the top and middle parts of the cylinder body 1. A feed pipe 2 is located at the top of the top support ring 19. The filter cylinder 18 is fixed inside the cylinder body 1 by the two support rings 19. The feed pipe 2 is located on the top left side of the top support ring 19, allowing the cutting fluid to accurately fall into the filter cylinder 18. The filter cylinder 18 then finely filters the cutting fluid, allowing it to flow through the perforations of the filter cylinder 18 to the outside of the filter cylinder 18, while impurities remain inside the filter cylinder 18.

[0035] A baffle 10 is provided inside the bottom end of the filter cylinder 18. First connecting rods 11 are fixedly connected to the left and right sides of the baffle 10. The outer sides of the two first connecting rods 11 pass through the inside of the bottom support ring 19 and are rotatably connected to the inside of the cylinder 1. A handle 12 is fixedly connected to the outer side of the other end of the left first connecting rod 11. The handle 12 is located at the bottom left side of the cylinder 1. When the impurities inside the filter cylinder 18 reach a certain level and block the filter cylinder 18 from sieving the cutting fluid, the operator pulls the handle 12 to drive the first connecting rod 11 to rotate. The first connecting rod 11 then drives the baffle 10 to rotate inside the support ring 19, thereby opening the outlet at the bottom end of the support ring 19 and discharging the impurities into the sludge storage hopper 13 for initial collection.

[0036] Before opening the baffle 10, the baffle 10 is kept closed to seal the bottom of the filter cartridge 18, effectively preventing the liquid being filtered from flowing into the bottom without being fully filtered, and ensuring that the cutting fluid completes the fine filtration process in the filter cartridge 18.

[0037] like Figure 1 - Figure 9 As shown, a sludge storage hopper 13 is fixedly connected to the bottom of the cylinder 1, and a drain pipe 14 is connected through the bottom of the sludge storage hopper 13. The sludge storage hopper 13 is used to temporarily collect impurities after screening. When cleaning is required, the drain pipe 14 is connected to external pipes to transport impurities to the next equipment and discharge them into the sludge storage hopper 13.

[0038] Each sludge hopper 13 is fixedly connected to a support leg 15, which supports the bottom of the entire device. A discharge pipe 16 is connected through the bottom right wall of the cylinder 1. A control valve 17 is installed on the outside of the discharge pipe 16. The left end of the discharge pipe 16 is located on the top right side of the bottom support ring 19. The cutting fluid filtered by the filter cartridge 18 falls into the top of the bottom support ring 19 and the outside of the filter cartridge 18, and is discharged through the discharge pipe 16 on the bottom left side of the cylinder 1. The control valve 17 controls the discharge pipe 16 to control the flow rate of the discharged cutting fluid.

[0039] like Figure 1 - Figure 12 As shown, a protective box 20 is fixedly connected to the top of the cylinder 1. A motor 21 is installed inside the protective box 20. The protective box 20 is used to protect the motor 21 from the outside and fix the motor 21 to the top of the cylinder 1.

[0040] A rotating rod 22 is fixedly connected to the output end of the motor 21. A second connecting rod 23 is fixedly connected to the outer side of the top of the rotating rod 22. Four connecting posts 24 are fixedly connected to both the left and right sides of the second connecting rod 23. A guide plate 25 is fixedly connected to the other end of each connecting post 24. After the motor 21 is started, the output end of the motor 21 drives the rotating rod 22 to rotate. When the rotating rod 22 rotates, the second connecting rod 23 on the outer side of the top rotates accordingly, thereby driving the connecting posts 24 and the guide plate 25 on the left and right sides to move together.

[0041] Each guide rail plate 25 has a second limiting block 26 fixedly connected to its bottom wall. Two second sliders 27 are slidably connected inside each guide rail plate 25. The second limiting block 26 on the bottom of the guide rail plate 25 limits the second sliders 27 inside the bottom of the guide rail plate 25, preventing them from being unable to be fixed inside the guide rail plate 25. The second sliders 27 also facilitate the installation and removal of the scraper 29 for cleaning and replacement. Furthermore, when the guide rail plate 25 is moved, the second sliders 27 installed inside the guide rail plate 25 can be rotated.

[0042] A support plate 28 is fixedly connected to the other side of each pair of second sliders 27. A scraper 29 is fixedly connected to the outer wall of each support plate 28. The outer walls of the four scrapers 29 are correspondingly set to the inside of the filter cylinder 18. The scrapers 29 are connected to the support plate 28 on the outside of the second slider 27 to install the scrapers 29 in the guide plate 25, so that the scrapers 29 can rotate inside the filter cylinder 18 and contact the inner wall of the filter cylinder 18 to scrape off the impurities adhering to the inner wall of the filter cylinder 18.

[0043] A sleeve 30 is fixedly connected to the outer side of the bottom end of the rotating rod 22. A connecting block 31 is fixedly connected to the bottom wall of the sleeve 30. A stirring paddle 32 is threadedly connected to the middle of the two connecting blocks 31. The stirring paddle 32 is fixed inside the two connecting blocks 31 by bolts through the connection between the sleeve 30 and the connecting blocks 31 on the bottom wall of the rotating rod 22. After the rotating rod 22 is driven to rotate, the sleeve 30 at the bottom end drives the stirring paddle 32 to rotate synchronously through the connecting blocks 31 to stir the cutting fluid.

[0044] It should be noted that this utility model is a cutting fluid flocculent filtration device for ultrathin silicon single crystal diamond wire slicing. First, the motor 21 is connected to an external power supply and control terminal to supply power to the device.

[0045] Cutting fluid containing flocculent material enters the filtration device through the feed pipe 2. Inside the feed pipe 2, the cutting fluid first passes through the coarse filter plate 7. The coarse filter plate 7 is installed by first sliders 8 on the outside of the fixing ring 6, which cooperate with the grooves 3 and mounting grooves 4 on the inner wall of the feed pipe 2. The four first sliders 8 slide along the grooves 3 into the mounting grooves 4 and are fixed by the first limiting blocks 5. The coarse filter plate 7 can intercept larger flocculent particles and impurities in the cutting fluid. The intercepted impurities will be discharged from the drain hole 9 at the bottom of the feed pipe 2 under the action of gravity, preventing impurities from accumulating and affecting the coarse filtration effect.

[0046] After coarse filtration, the cutting fluid enters the filter cartridge 18 inside the cylinder 1. The filter cartridge 18 is fixed inside the cylinder 1 by support rings 19 at both ends, which can further remove smaller-sized flocculent matter and fine impurities from the cutting fluid. In this process, the baffle 10 plays a key role. It is located inside the bottom of the filter cartridge 18 and is connected to the cylinder 1 by the first connecting rods 11 on the left and right sides. During normal filtration, the baffle 10 remains closed, sealing the bottom of the filter cartridge 18, effectively preventing the liquid being filtered from flowing to the bottom without being fully filtered, and ensuring that the cutting fluid completes the fine filtration process in the filter cartridge 18. When it is necessary to clean the filter cartridge 18, turn the handle 12. The handle 12 drives the first connecting rod 11 on the left to rotate, thereby causing the baffle 10 to rotate and open around the first connecting rod 11. The impurities trapped in the filter cartridge 18 fall into the sludge storage hopper 13 below for temporary storage under the action of gravity.

[0047] The filtered clean cutting fluid is discharged through the discharge pipe 16. By opening the control valve 17, the clean cutting fluid can flow out through the discharge pipe 16 and re-enter the cutting fluid circulation system or storage tank for use in subsequent slicing processes. Impurities collected in the sludge hopper 13 can be centrally cleaned and discharged through the bottom drain pipe 14 to ensure the continuous and stable operation of the entire filtration device.

[0048] After coarse filtration, the cutting fluid enters the filter cartridge 18 inside the cylinder 1. At this time, the motor 21 located in the protective box 20 at the top of the cylinder 1 starts to work, and the output end of the motor 21 drives the rotating rod 22 to rotate. When the rotating rod 22 rotates, the second connecting rod 23 on the outer side of the top rotates accordingly, which in turn drives the connecting columns 24 on the left and right sides and the guide rail plate 25 to move together. The second slider 27 in the guide rail plate 25 can slide in the guide rail plate 25, and at the same time, it moves in a circle around the rotating rod 22 with the guide rail plate 25. The four scrapers 29 are closely attached to the inner wall of the filter cartridge 18, and continuously scrape off the flocculent matter and impurities attached to the inner wall of the filter cartridge 18 during the movement, preventing these impurities from accumulating and affecting the filtration effect, and ensuring the filtration efficiency of the filter cartridge 18.

[0049] At the same time, the sleeve 30, connecting block 31, and stirring paddle 32 on the outer side of the bottom end of the rotating rod 22 also rotate together with the rotating rod 22. The stirring paddle 32 stirs the cutting fluid in the filter cylinder 18, so that the flocculent matter in the cutting fluid can be more evenly dispersed in the liquid, avoiding the accumulation of flocculent matter. On the one hand, it is beneficial for the filter cylinder 18 to intercept and filter flocculent matter, and on the other hand, it can also prevent uneven local concentration of cutting fluid caused by flocculent matter precipitation, thus improving the overall filtration effect.
