Description

Technical Field

[0001] This utility model relates to the field of steel ball grinding fluid treatment technology, specifically a high-precision steel ball grinding fluid recycling and treatment device. Background Technology

[0002] In existing technologies, grinding is one of the important processes in the machining of high-precision steel balls. In order to improve the grinding efficiency and enhance the grinding quality of high-precision steel balls, grinding fluid is sprayed on the surface of the high-precision steel balls. The grinding fluid carries the debris generated during the grinding process and flows out, generating waste grinding fluid for high-precision steel balls. If the grinding fluid is discarded directly, it will not only waste resources but also increase the production cost of the workpiece. The existing methods are mostly to treat the high-precision grinding fluid and then recycle it.

[0003] For example, the patent application number 201811241019.X discloses a bearing steel ball grinding fluid iron filings separation device, which solves the problem that the grinding fluid cannot be recycled, but it has problems such as low separation rate of filings and grinding fluid, poor filtration effect of grinding fluid, and a lot of waste of grinding fluid.

[0004] Based on this, the applicant proposes a high-precision steel ball grinding fluid recovery and treatment device. Utility Model Content

[0005] The purpose of this invention is to address the problems of low separation rate of debris and grinding fluid, poor filtration effect of grinding fluid, and excessive waste of grinding fluid in existing high-precision steel ball grinding fluid treatment devices, and to provide a high-precision steel ball grinding fluid recycling and treatment device with reasonable structural design, high separation rate of debris and grinding fluid, good filtration effect of grinding fluid, and low waste of grinding fluid.

[0006] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0007] A high-precision steel ball grinding slurry recycling and treatment device includes a base tank, a filter tank, a rotating shaft, and a pump. The base tank has a vertical plate on top and a fine filter layer inside. An inlet chamber, a fixing ring, and a drive structure are located on top of the vertical plate. The multiple fine filter layers inside the base tank effectively filter the grinding slurry, improving its filtration efficiency and effect, allowing for direct use of the filtered slurry, and enabling its recycling, thus reducing waste. The filter tank is positioned between the vertical plates and has a sealing ring and filter holes at its bottom. Multiple filter tanks between the vertical plates allow for multiple filtrations of the grinding slurry entering the base tank, effectively improving its purification effect. The rotating shaft... The top end of the rotating shaft passes through the fixed ring, and the bottom end of the rotating shaft passes through the sealing ring and enters the bottom chamber. The rotating shaft is connected to the drive structure, and a lever is set on the rotating shaft inside the filter chamber. The drive structure drives the rotating shaft to rotate, causing the lever on the rotating shaft to agitate the grinding fluid in the filter chamber, thus fully filtering the grinding fluid. The grinding fluid quickly passes through the filter holes at the bottom of the filter chamber and enters the filter chamber or bottom chamber below for rapid filtration, improving the filtration efficiency and effect of the grinding fluid. The infusion pump is set on the top plate, and a suction pipe and a discharge pipe are set on the infusion pump. The bottom end of the suction pipe extends into the bottom chamber. The infusion pump draws out the grinding fluid after it has been filtered by the fine filter layer in the bottom chamber through the suction pipe and discharges it through the discharge pipe, realizing the reuse of the grinding fluid and reducing waste.

[0008] Preferably, the number of fine filter layers in the bottom box is 2-4, with the mesh size of the fine filter layers increasing sequentially from the inner wall of the bottom box to the center. The grinding liquid, after being filtered by multiple filter boxes, enters the bottom box and flows from the inner wall to the center of the bottom box. After being filtered through multiple layers of fine filter layers, it is drawn out from the suction pipe by the action of the infusion pump, and the grinding liquid is recycled, reducing the waste of the grinding liquid.

[0009] Preferably, the number of filter boxes is set to 2-5, and the diameter of the filter holes at the bottom of each filter box is set to decrease sequentially from the top filter box to the bottom filter box. The grinding liquid to be recycled is poured into the top filter box through the inlet chamber, and the grinding liquid falls into the bottom filter box through the filter holes at the bottom of the top filter box. Multiple filter boxes perform multiple filtration processes on the grinding liquid, so that impurities of different sizes remain in the filter boxes. The grinding liquid filtered by the bottom filter box falls into the bottom box, which can improve the filtration effect of the grinding liquid and facilitate the recycling of the grinding liquid.

[0010] Preferably, a primary filter cartridge is provided at the bottom of the top plate and is connected to the liquid inlet chamber. The grinding liquid to be recycled is poured into the uppermost filter box through the liquid inlet chamber. The primary filter cartridge can perform preliminary filtration of large particulate impurities in the grinding liquid, preventing large particulate impurities from entering the filter box and bottom box, thereby reducing the difficulty of subsequent filtration of the grinding liquid, improving the recycling efficiency and treatment effect of the grinding liquid, and facilitating the recycling of the grinding liquid.

[0011] Preferably, the drive structure includes a motor mounted on a top plate, a drive shaft mounted on the motor, a drive wheel mounted on the drive shaft, and a driven wheel mounted on the rotating shaft. The driven wheel is connected to the drive wheel via a transmission belt. The motor drives the drive shaft and the drive wheel on the drive shaft to rotate, and the drive wheel drives the driven wheel to rotate via the transmission belt, thereby causing the rotating shaft to rotate within a fixed ring. The rotating shaft drives a lever to rotate, causing the lever on the rotating shaft to agitate the grinding fluid in the filter box, thus fully filtering the grinding fluid and allowing it to quickly pass through the filter holes at the bottom of the filter box into the lower filter box or bottom box, rapidly filtering the grinding fluid and improving its filtration efficiency and effect.

[0012] Preferably, the rotating shaft inside the filter box has a scraper on its actuating rod, and a through groove on the scraper. The rotating shaft drives the actuating rod to rotate, and the scraper pushes the grinding liquid and impurities to move inside the filter box. The through groove allows impurities to pass through, and the grinding liquid enters the filter box or bottom box below through the filter holes for thorough filtration. This improves the treatment effect of the grinding liquid, facilitates its recycling, and reduces waste.

[0013] Preferably, a drop plate is installed on the rotating shaft below the lowest filter box via an mounting ring, and the drop plate is configured as an inverted funnel shape. The grinding liquid in the lowest filter box falls onto the drop plate after being filtered through the filter holes, and flows downward along the inclined surface of the drop plate, so that the grinding liquid falls into the bottom box from the edge of the drop plate, avoiding the grinding liquid falling outside the bottom box, reducing the waste of grinding liquid, and facilitating the further fine filtration of the grinding liquid entering the bottom box. The drop plate can prevent the grinding liquid that has not undergone fine filtration from being drawn out by the infusion pump, thereby improving the recycling effect of the grinding liquid.

[0014] Preferably, the rotating shaft is a hollow structure. The suction tube is vertically inserted into the rotating shaft and then extends into the bottom box. A rotating ring is provided between the inner wall of the rotating shaft and the suction tube. The motor drives the transmission shaft and the drive wheel on the transmission shaft to rotate. The drive wheel drives the driven wheel to rotate through the transmission belt, thereby driving the rotating shaft to rotate within the fixed ring. The rotating ring facilitates the rotation of the rotating shaft around the suction tube. The infusion pump draws the grinding liquid, which has been filtered through the fine filter layer in the bottom box, through the suction tube and discharges it through the drain pipe, realizing the reuse of the grinding liquid and reducing waste. The suction tube draws the grinding liquid from the middle of the bottom box, causing the grinding liquid in the bottom box to flow from the inner wall to the middle of the bottom box. After being filtered through multiple layers of fine filter layer, it is drawn out from the suction tube under the action of the infusion pump, and the grinding liquid is recycled, reducing waste.

[0015] Beneficial effects:

[0016] 1. The grinding slurry that needs to be recycled is poured into the uppermost filter box through the inlet chamber. The grinding slurry falls into the lower filter box through the filter holes at the bottom of the filter box. Multiple filter boxes filter the grinding slurry multiple times, leaving impurities of different sizes in the filter boxes. The grinding slurry filtered by the lower filter box falls into the bottom box, which can improve the filtration effect of the grinding slurry and facilitate its recycling.

[0017] 2. A drop plate is installed on the rotating shaft below the bottom filter box via an mounting ring. The drop plate is designed as an inverted funnel. The grinding liquid in the bottom filter box is filtered through the filter holes and falls onto the drop plate. It flows downward along the inclined surface of the drop plate, allowing the grinding liquid to fall from the edge of the drop plate into the bottom box. This facilitates further fine filtration of the grinding liquid entering the bottom box. The drop plate also prevents the grinding liquid that has not undergone fine filtration from being drawn out by the infusion pump, thereby improving the recycling effect of the grinding liquid.

[0018] 3. The infusion pump draws the polishing solution, filtered through the fine filtration layer, from the bottom tank via the suction pipe and discharges it through the drain pipe, enabling the reuse of the polishing solution and reducing waste. The suction pipe draws the polishing solution from the middle of the bottom tank, causing it to flow from the inner wall to the center. After passing through multiple fine filtration layers, the polishing solution is drawn out through the suction pipe by the infusion pump, recycling the polishing solution and minimizing waste.

[0027] The present invention will now be described in more detail with reference to the accompanying drawings.

[0028] Example 1:

[0029] As attached Figure 1-5 As shown, a high-precision steel ball grinding fluid recovery and treatment device includes a base box 1, a filter box 2, a rotating shaft 3, and an infusion pump 4. The top of the base box 1 is provided with a vertical plate 5, and a fine filter layer 6 is provided inside the base box 1. The top of the vertical plate 5 is provided with an inlet chamber 8, a fixing ring 9, and a drive structure. The filter box 2 is located between the vertical plates 5. The bottom of the filter box 2 is provided with a sealing ring 14 and filter holes 15. The top end of the rotating shaft 3 passes through the fixing ring 9, and the bottom end of the rotating shaft 3 passes through the sealing ring 14 and enters the bottom box 1. The rotating shaft 3 is connected to the drive structure. An actuating rod 17 is provided on the rotating shaft 3 inside the filter box 2. The infusion pump 4 is located on the top plate 7. The infusion pump 4 is provided with a suction pipe 23 and a discharge pipe 24, and the bottom end of the suction pipe 23 extends into the bottom box 1.

[0030] The bottom box 1 contains two fine filter layers 6, with the mesh size of the fine filter layers 6 increasing sequentially from the inner wall of the bottom box 1 towards the middle of the bottom box 1. The number of filter boxes 2 is set to two, and the diameter of the filter holes 15 at the bottom of each filter box 2 is set to decrease sequentially from the uppermost filter box 2 to the lowermost filter box 2. The bottom of the top plate 7 is provided with a primary filter cylinder 11, which is connected to the liquid inlet chamber 8.

[0031] The drive structure includes a motor 10, which is mounted on the top plate 7. A drive shaft 12 is mounted on the motor 10, and a drive wheel 13 is mounted on the drive shaft 12. A driven wheel 16 is mounted on the rotating shaft 3, and the driven wheel 16 is connected to the drive wheel 13 via a transmission belt 19. A scraper 20 is mounted on the actuation rod 17 of the rotating shaft 3 inside the filter box 2, and a through groove 21 is mounted on the scraper 20.

[0032] Among them, a liquid drop plate 22 is set on the rotating shaft 3 below the bottom filter box 2 through the mounting ring 18, and the liquid drop plate 22 is set as an inverted funnel-shaped structure. The rotating shaft 3 is set as a hollow structure. The liquid suction pipe 23 is vertically inserted into the rotating shaft 3 and then extends into the bottom box 1. A rotating ring 25 is set between the inner wall of the rotating shaft 3 and the liquid suction pipe 23.

[0033] Example 2:

[0034] Further explanation is provided based on Example 1, as shown in the appendix. Figure 6-7 As shown, a high-precision steel ball grinding fluid recycling and treatment device is provided with a splash guard 26 on the liquid drop plate 22. The rotating shaft 3 drives the liquid drop plate 22 to rotate, so that the grinding fluid filtered by the bottom filter box 2 falls onto the liquid drop plate 22 and falls from the edge of the liquid drop plate 22 into the bottom box 1. The splash guard 26 can prevent the liquid drop plate 22 from being thrown off the surface of the liquid drop plate 22 under the action of centrifugal force during the rotation process, so that the grinding fluid on the liquid drop plate 22 can flow into the bottom box 1 in full, reducing the waste of grinding fluid.

[0035] Working principle: The used grinding fluid that needs to be recycled is poured into the inlet chamber 8. The primary filter cartridge 11 performs preliminary filtration of large particles in the grinding fluid. The grinding fluid after filtration by the primary filter cartridge 11 falls into the uppermost filter box 2. The motor 10 is started, driving the drive shaft 12 and the drive wheel 13 on the drive shaft 12 to rotate. The drive wheel 13 drives the driven wheel 16 to rotate via the transmission belt 19, thereby driving the rotating shaft 3 to rotate within the fixed ring 9. The rotating shaft 3 drives the agitator 17 to rotate, causing the agitator 17 on the rotating shaft 3 to agitate the grinding fluid in the filter box 2. The scraper 20 on the agitator 17 pushes the grinding fluid and impurities to move within the filter box 2. The through groove 21 allows impurities to pass through, allowing the grinding fluid to enter the lower filter box 2 or the bottom box 1 through the filter holes 15 for further processing. The grinding slurry undergoes thorough filtration. The grinding slurry in the upper filter box 2 falls through the filter holes 15 into the adjacent lower filter box 2. The grinding slurry in the lowest filter box 2 falls onto the drop plate 22 after being filtered through the filter holes 15. It flows downward along the inclined surface of the drop plate 22, allowing the grinding slurry to fall from the edge of the drop plate 22 into the bottom box 1. The infusion pump 4 is started, and the infusion pump 4 extracts the grinding slurry that has been filtered through the fine filter layer 6 in the bottom box 1 through the suction pipe 23 and discharges it through the drain pipe 24, realizing the reuse of the grinding slurry and reducing waste. The suction pipe 23 extracts the grinding slurry in the middle of the bottom box 1, allowing the grinding slurry in the bottom box 1 to flow from the inner wall of the bottom box 1 to the middle of the bottom box 1. After passing through multiple layers of fine filter layers 6, the grinding slurry in the bottom box 1 undergoes fine filtration treatment, completing the recycling treatment of the grinding slurry.
