Description

Technical Field

[0001] This utility model belongs to the field of cleaning machine technology, specifically relating to an ultrasonic cleaning machine for metal powder. Background Technology

[0002] Metal particles with a diameter of less than 1 mm are called metal powders. Metal powders refer to groups of metal particles smaller than 1 mm, including single metal powders, alloy powders, and powders of certain refractory compounds with metallic properties. Metal powders are the main raw material for powder metallurgy and are widely used in the automotive, aerospace, electronics, machinery, and construction industries. In the automotive and aerospace industries, metal powders are used to produce lightweight and high-precision components to meet the demands for energy saving and high efficiency. Furthermore, metal powders are also used in high-tech fields such as 3D printing and microelectronic welding.

[0003] In existing technologies, metal powder is often immersed in a cleaning tank for ultrasonic cleaning. The dirt, grease, rust and other impurities removed by the cleaning float in the cleaning solution. After cleaning, some dirt, grease, rust and other impurities are still deposited on the surface of the metal powder, resulting in poor cleaning effect. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an ultrasonic cleaning machine for metal powder, which features high cleaning efficiency, thorough cleaning without dead angles, and excellent cleaning effect.

[0005] The technical solution adopted in this utility model is as follows.

[0006] An ultrasonic cleaning machine for metal powder includes a frame; an overflow trough is provided on the frame; a liquid collection trough is provided on the outer periphery of the overflow trough, the liquid collection trough includes a sleeve with a rectangular horizontal cross-section and a horizontal ring plate located on the outer side of the overflow trough, the bottom surface of the sleeve is connected to each side wall of the overflow trough through the horizontal ring plate; a roller rotating frame is installed on the overflow trough; a liquid outlet is provided on the liquid collection trough; an ultrasonic device is provided on the overflow trough; a roller is placed on the roller rotating frame; a plurality of first micro-holes are provided on the radial outer peripheral surface of the roller; a left opening is provided at the left end of each roller, and a right opening is provided at the right end of each roller; a blocking ring is coaxially provided on the inner peripheral surface of the roller near the left and right openings; a right end cover is movably connected to the right opening.

[0007] The left end of the sleeve on the frame is connected to the left end cover lateral movement drive device and the nozzle lateral movement drive device. The left end cover lateral movement drive device is equipped with a left end cover perpendicular to the ground. The center of the left end cover is provided with a nozzle through hole in the middle. The nozzle lateral movement drive device is connected to the nozzle, and the nozzle passes through the nozzle through hole.

[0008] The nozzle is connected to an external cleaning fluid supply device; the drum rotating frame is connected to a drive device located on the right side wall of the sleeve.

[0009] When a drum is connected to the drum rotating frame, the left end cover is driven to close the left opening of the drum by the left end cover lateral movement drive device, and the nozzle is driven to enter the drum by the nozzle lateral movement drive device and spray cleaning liquid through the nozzle.

[0010] Its beneficial effects are as follows: During operation, the right end cover of the roller is fastened, and a certain amount of metal powder is placed inside the roller, with the thickness of the metal powder being lower than the radial thickness of the blocking ring. The roller is placed on the roller rotating frame of the overflow tank; the left end cover closes the left opening of the roller through the left end cover lateral movement drive device, and the nozzle is driven by the nozzle lateral movement drive device to enter the roller for cleaning fluid spraying. The roller rotating frame drives the roller to rotate along its central axis, and at the same time, the ultrasonic device is activated; high-frequency sound waves are generated in the liquid medium through ultrasonic waves. These sound waves form countless tiny bubbles during propagation. These bubbles rapidly form and collapse during the compression and rarefaction of the sound waves, forming a powerful impact force, i.e., the ultrasonic cavitation effect. This effect can penetrate into tiny gaps and holes, effectively removing dirt, grease, rust, graphite powder, and other impurities from the surface of the metal powder without damaging the structure of the metal powder. Impurities accumulate on the surface of the cleaning fluid, and as the cleaning fluid overflows from the overflow tank, it continuously enters the collection tank and flows out from the outlet of the collection tank. Ultrasonic waves separate impurities from metal particles, while a spray system blows impurities out of the drum. The drum's continuous rotation ensures all metal particles are sprayed, and overflow continuously removes impurities, maintaining the cleanliness of the cleaning solution in the overflow tank. This system is designed for cleaning metal particles with a diameter not exceeding 1mm. The ultrasonic cleaning function removes surface graphite powder. The equipment features overflow, spraying, rapid discharge, and rotation. Ultrasonic waves separate impurity powder from metal particles, and the spray system blows the impurity powder out through the first micro-hole of the drum into the overflow tank. A sleeve with a left-end cover lateral movement drive is connected to the left end, allowing the left end cover to be closed during cleaning, preventing the cleaning material from overflowing. A spray nozzle lateral movement drive allows the nozzle to move laterally, ensuring thorough cleaning without dead zones. After cleaning, it reduces the dispersion of dirt, grease, rust, and other impurities in the overflow tank, preventing their deposition on the surface of the cleaned metal powder, resulting in excellent cleaning performance.

[0011] As a preferred technical solution, the roller rotating frame includes a horizontal rotating shaft support set at the bottom of the overflow trough, two horizontal rotating shafts installed on the horizontal rotating shaft support, and a vertical plate set on the right side of the horizontal rotating shaft support inside the overflow trough; the vertical plate is provided with two rotating shaft through holes of the same height, and each horizontal rotating shaft passes through one rotating shaft through hole; the right end of each horizontal rotating shaft is coaxially connected to a first transmission gear; the left end of each horizontal rotating shaft is coaxially connected to a second transmission gear; the two horizontal rotating shafts are of the same height and are symmetrical about the centroid of the overflow trough and are both perpendicular to the vertical plate.

[0012] As a preferred technical solution, the driving device includes a horizontally arranged drive motor, the output shaft of which is provided with a drive gear, which meshes with two first transmission gears; a third transmission gear is provided on each horizontal rotating shaft near the left side of the vertical plate; a roller gear ring is coaxially provided at both the left and right ends of the roller; when the roller is placed on the roller rotating frame, the roller gear ring at the left end of the roller contacts the second transmission gear on the left end of each horizontal rotating shaft, and the roller gear ring at the right end of the roller contacts the third transmission gear on each horizontal rotating shaft.

[0013] This technical solution uses the drive motor's active gear to rotate two first transmission gears, which in turn drive the second transmission gear on the left end of the horizontal rotating shaft and the third transmission gear on each horizontal rotating shaft to rotate. This, in turn, drives the two roller gear rings of the drum to rotate, allowing the drum to rotate in the cleaning liquid in the overflow tank during the cleaning process.

[0014] As a preferred technical solution, the top of the upright plate has a first groove with an upward opening at the center, and a first bearing is provided on the first groove; the top of the right side wall of the sleeve has a second groove with an upward opening at the center, and a second bearing is provided on the second groove; the top of the right side wall of the overflow groove has a third groove with an upward opening at the center, and a third bearing is provided on the third groove; the output shaft of the drive motor is connected to the first bearing, the second bearing, and the third bearing.

[0015] Using this technical solution, the drum rotation is more stable, and the cleaning is more thorough.

[0016] As a preferred technical solution, the frame is equipped with a cleaning fluid filter box, the outlet is connected to the cleaning fluid filter box through a pipeline, and the cleaning fluid filter box is equipped with a drain port.

[0017] This technical solution allows for the filtration of waste residue generated during cleaning, facilitating the recycling of the cleaning solution. The cleaning solution can be water or acid.

[0018] As a preferred technical solution, a liquid pump is installed on the pipeline between the liquid outlet and the cleaning liquid filter box.

[0019] This technical solution allows for smoother filtration and cleaning processes.

[0020] As a preferred technical solution, the left and right end caps are provided with several second micropores.

[0021] This technical solution facilitates the entry of impurities into the overflow tank through the second micropore.

[0022] As a preferred technical solution, the left end cover lateral movement drive device includes a first horizontal panel disposed on the left side of the sleeve on the frame, two lateral slide rails disposed on the first horizontal panel, a sliding frame, and a first lateral movement drive device. The first lateral movement drive device is connected to the sliding frame, and the sliding frame is mounted on the two lateral slide rails. The sliding frame is connected to two crossbars of equal length, and the left end cover is connected to the right end of the two crossbars. A fourth groove with an upward opening is provided in the middle of the top of the left side wall of the sleeve. A fifth groove with an upward opening is provided in the middle of the top of the right side wall of the overflow groove. Both crossbars pass through the fourth groove and the fifth groove.

[0023] The nozzle lateral movement drive device includes a second horizontal panel that is laterally arranged on the sliding frame. A second lateral movement drive device is laterally arranged on the second horizontal panel. The output shaft of the second lateral movement drive device is connected to the nozzle through a longitudinal connecting plate.

[0069] The present invention will now be further described in conjunction with the accompanying drawings and embodiments.

[0070] Example 1. As... Figure 1-30 As shown, an ultrasonic cleaning machine for metal powder includes a frame 1; the frame 1 is provided with an overflow trough 3.

[0071] An overflow tank 3 is provided with a collection tank on its outer periphery. The collection tank includes a sleeve 41 with a rectangular horizontal cross-section and a horizontal ring plate 42 located on the outer side of the overflow tank 3. The bottom surface of the sleeve 41 is connected to each side wall of the overflow tank 3 through the horizontal ring plate 42. The collection tank is used to collect the cleaning fluid overflowing from the top of the overflow tank 3.

[0072] A roller rotating frame 8 is installed on the overflow tank 3; a liquid outlet 43 is provided on the liquid collection tank; an ultrasonic device 5 is provided on the overflow tank 3; a roller 2 is placed on the roller rotating frame 8; a plurality of first micropores are provided on the radial outer circumferential surface of the roller 2. The first micropores are not shown in the attached figure.

[0073] like Figure 14-18 As shown in Figures 26-29, each roller 2 has a left opening 21 at its left end and a right opening 22 at its right end; a blocking ring 23 is provided coaxially on the inner circumferential surface of the roller 2 near the left opening 21 and the right opening 22; a right end cover 24 is movably connected to the right opening 22.

[0074] like Figure 30 As shown, when the roller 2 is filled with metal powder 10, the thickness of the metal powder 10 is less than the thickness of the blocking ring 23. The blocking ring 23 is used to prevent the metal powder 10 from flowing out from the left opening 21 and the right opening 22 when the roller 2 is placed on the roller rotating frame 8.

[0075] like Figure 5-9As shown, the left end of the sleeve 41 on the frame is connected to the left end cover lateral movement drive device 6 and the nozzle lateral movement drive device 7. The left end cover lateral movement drive device 6 is provided with a left end cover 25 perpendicular to the ground.

[0076] like Figure 14-18 As shown, a nozzle through-hole 26 is provided in the center of the left end cover 25. The nozzle lateral movement drive device 7 is connected to the nozzle 70, and the nozzle 70 passes through the nozzle through-hole 26. A roller 2 is movably connected to the roller rotating frame 8. A cleaning fluid supply device is connected to the nozzle 70. The cleaning fluid supply device is not shown in the figure.

[0077] The roller rotating frame 8 is connected to the drive device 9, which is located on the right side wall of the sleeve 41.

[0078] When the roller 2 is connected to the roller rotating frame 8, the left end cover 25 is driven by the left end cover lateral movement drive device 6 to close the left opening 21 of the roller 2, and the spray pipe 70 is driven by the spray pipe lateral movement drive device 7 to enter the roller 2 and spray cleaning liquid through the spray pipe 70.

[0079] Its beneficial effects are as follows: During operation, the right end cover 24 is fastened onto the roller 2, and a certain amount of metal powder is placed into the roller 2, the thickness of which is lower than the radial thickness of the blocking ring 23. The roller 2 is then placed on the roller rotating frame 8 of the overflow trough 3.

[0080] like Figure 22-23 As shown, the left end cover 25 closes the left opening 21 of the drum 2 through the left end cover lateral movement drive device 6, and the spray nozzle 70 is driven into the drum 2 by the spray nozzle lateral movement drive device 7 to spray the cleaning liquid.

[0081] The rotating drum frame 8 drives the drum 2 to rotate along its central axis, while the ultrasonic device 5 is activated. High-frequency sound waves are generated in the liquid medium through ultrasonic waves. These sound waves form countless tiny bubbles during propagation. These bubbles rapidly form and collapse during the compression and rarefaction of the sound waves, creating a powerful impact force—the ultrasonic cavitation effect. This effect can penetrate into tiny gaps and pores, effectively removing dirt, grease, rust, graphite powder, and other impurities from the surface of metal powder without damaging its structure. Impurities accumulate on the surface of the cleaning fluid and, as the cleaning fluid overflows from the overflow tank 3, continuously enter the collection tank and flow out from the outlet 43. Ultrasonic waves separate impurities from metal particles, and spraying blows the impurities out of the drum 2. The continuous rotation of the drum 2 ensures that all metal particles are sprayed, and the overflow continuously removes impurities, ensuring the cleanliness of the cleaning fluid in the overflow tank 3. This ultrasonic cleaning system removes graphite powder from the surface of metal particles with a diameter not exceeding 1mm. The equipment features overflow, spraying, rapid discharge, and rotation. Ultrasonic waves separate impurities and metal particles, while spraying blows the impurities out through the first micro-hole of the drum 2 into the overflow tank 3. A left-end cover lateral movement drive 6 is connected to the left end of the sleeve 41, allowing the left end cover to be closed during cleaning, preventing the cleaned material from overflowing. A spray nozzle lateral movement drive 7 allows the nozzle to move laterally, ensuring thorough cleaning without dead zones. After cleaning, it reduces the dispersion of dirt, grease, rust, and other impurities in the overflow tank, preventing their deposition on the surface of the cleaned metal powder, resulting in excellent cleaning performance.

[0082] The roller rotating frame 8 includes a horizontal rotating shaft support 81 set at the bottom of the overflow trough 3, two horizontal rotating shafts 82 mounted on the horizontal rotating shaft support 81, and a vertical plate 83 set on the right side of the horizontal rotating shaft support 81 in the overflow trough 3; the vertical plate 83 is provided with two rotating shaft through holes of the same height, and each horizontal rotating shaft 82 passes through one rotating shaft through hole; the right end of each horizontal rotating shaft 82 is coaxially connected to a first transmission gear 84; the left end of each horizontal rotating shaft 82 is coaxially connected to a second transmission gear 85; the two horizontal rotating shafts 82 are of the same height and are symmetrical about the centroid of the overflow trough 3 and are both perpendicular to the vertical plate 83.

[0083] The drive unit 9 includes a horizontally arranged drive motor 91, with a drive gear 93 on the output shaft 92 of the drive motor. The drive gear 93 meshes with two first transmission gears 84. A third transmission gear 86 is located on each horizontal rotating shaft 82 near the left side of the vertical plate 83. Roller gear rings 27 are coaxially arranged at both the left and right ends of the roller 2. When the roller 2 is placed on the roller rotating frame 8, the roller gear ring 27 at the left end of the roller 2 contacts the second transmission gear 85 at the left end of each horizontal rotating shaft 82, and the roller gear ring 27 at the right end of the roller 2 contacts the third transmission gear 86 on each horizontal rotating shaft 82. Using this technical solution, the drive gear 93 of the drive motor 91 drives the two first transmission gears 84 to rotate, which in turn drives the second transmission gear 85 at the left end of the horizontal rotating shaft 82 and the third transmission gear 86 on each horizontal rotating shaft 82 to rotate, thereby driving the two roller gear rings 27 of the roller 2 to rotate. This allows the roller to rotate in the cleaning liquid in the overflow tank during the cleaning process.

[0084] The top center of the upright plate 83 has a first groove 831 with an upward opening, and a first bearing 832 is mounted on the first groove 831; the top center of the right side wall of the sleeve 41 has a second groove 411 with an upward opening, and a second bearing 412 is mounted on the second groove 411; the top center of the right side wall of the overflow groove 3 has a third groove 31 with an upward opening, and a third bearing 32 is mounted on the third groove 31; the output shaft 92 of the drive motor is connected to the first bearing 832, the second bearing 412, and the third bearing 32. The rotation of the drum is relatively stable, and the cleaning is relatively thorough.

[0085] like Figure 14-16 As shown, a cleaning fluid filter box 11 is provided on the frame 1, and the outlet 43 is connected to the cleaning fluid filter box 11 through a pipe 12. Figure 13 As shown, the cleaning fluid filter tank 11 is equipped with a drain port 13. This can filter the waste residue generated during cleaning, facilitating the recycling of the cleaning fluid. The cleaning fluid is water or acid. A pump 14 is installed on the pipeline between the drain port 43 and the cleaning fluid filter tank 11; this technical solution ensures smoother filtration and cleaning processes.

[0086] The left end cap 25 and the right end cap 24 are provided with several second micro-holes. This technical solution facilitates the entry of impurities into the overflow tank through the second micro-holes.

[0087] like Figure 5-7 , Figure 14-16 As shown, the left end cover lateral movement drive device 6 includes a first horizontal panel 61 disposed on the left side of the sleeve 41 on the frame, two lateral slide rails 65 disposed on the first horizontal panel 61, a sliding frame 62, and a first lateral movement drive device 63. The first lateral movement drive device 63 is connected to the sliding frame 62, and the sliding frame 62 is mounted on the two lateral slide rails 65. The sliding frame 62 is connected to two crossbars 64 of equal length, and the left end cover 25 is connected to the right end of the two crossbars 64. Figure 6 , Figure 15 , Figure 23 , Figure 25 As shown, the first transverse drive device 63 drives the sliding frame 62 to move laterally, and the sliding frame 62 drives the left end cover 25 to move laterally via two equal-length crossbars 64, thereby closing the left opening 21 of the roller. The first transverse drive device 63 is an electric actuator. In another example, the first transverse drive device 63 is an electric screw.

[0088] like Figure 14-16 As shown, the nozzle lateral movement drive device 7 includes a second horizontal panel 71 horizontally arranged on the sliding frame 62. A second lateral movement drive device 72 is horizontally arranged on the second horizontal panel 71. The output shaft 721 of the second lateral movement drive device is connected to the nozzle 70 via a longitudinal connecting plate 73. A nozzle 74 with its central axis perpendicular to the central axis of the nozzle 70 is located near the drive device 9 end of the nozzle 70. Using this technical solution, the drum rotation is relatively stable. The nozzle lateral movement drive device 7 drives the longitudinal connecting plate 73 to move laterally, which in turn drives the nozzle 70 to move laterally, enabling the nozzle 74 to move within the drum, ensuring thorough cleaning without dead angles. In this embodiment, the second horizontal panel 71 is arranged on the sliding frame 62, saving installation space. Of course, the second horizontal panel 71 can also be installed on the frame, with the nozzle lateral movement drive device 7 and the left end cover lateral movement drive device 6 being independently arranged.

[0089] The second lateral movement drive is an electric actuator. In another example, the second lateral movement drive is an electric screw.

[0090] like Figure 19 As shown, the top of the left side wall of the sleeve 41 is provided with a fourth groove 413 with an upward opening at the middle; the top of the right side wall of the overflow groove 3 is provided with a fifth groove 33 with an upward opening at the middle; both crossbars 64 pass through the fourth groove 413 and the fifth groove 33.

[0091] The frame is equipped with a roller storage bracket 15. Another spare roller 2 is placed on the roller storage bracket 15.

The right end cover 24 and the left end cover 25 each have three positioning protrusion locking grooves 29 arranged in a ring along the central axis, which are adapted to the size of the positioning protrusions 28.
