Description

Technical Field

[0001] This utility model belongs to the field of auxiliary equipment for ball mills, and specifically relates to an agate ball cleaning device for a planetary ball mill. Background Technology

[0002] In the field of soil environmental testing, especially in precision testing scenarios such as heavy metal content analysis and trace element quantitative detection, the precision of sample preparation directly determines the accuracy and reliability of the test results. To ensure that subsequent steps such as acid digestion, solvent extraction, or direct spectral analysis can fully react and that the data is stable, soil samples need to be ground to micron or even nanometer-level fine particles. Furthermore, the sample particles must be uniformly distributed and have good representativeness to avoid detection errors caused by uneven particle size or component segregation.

[0003] Planetary ball mills, with their unique combined revolution and rotation principle, offer significant advantages over traditional grinding equipment, including high grinding efficiency, fine material refinement, uniform sample particle size, and excellent consistency and reproducibility in batch processing. They have become the core equipment for soil sample preparation in various environmental testing laboratories. Regarding the choice of grinding media, agate, with its high hardness, high wear resistance, excellent chemical inertness (not reacting with soil components or subsequent testing reagents), and its absence of metallic impurities and low risk of introducing secondary metal contamination, perfectly matches the stringent purity requirements for heavy metal and trace element testing in soil. Therefore, it has become the preferred grinding ball material for planetary ball mills when grinding soil samples.

[0004] However, in practical applications, the cleaning of agate grinding balls has become a key bottleneck restricting the efficiency of soil sample preparation. Due to the microporous structure on the surface of agate balls, and the fact that a single grinding operation requires a large number of balls (usually dozens to hundreds), fine-diameter soil particles adhere deeply to the surface and pores of the agate balls after grinding, forming a strong adhesion layer that is difficult to remove completely. Currently, the industry commonly uses manual brushing for cleaning, requiring operators to manually brush each agate ball, a cumbersome and time-consuming process. Especially when processing large batches of soil samples in the laboratory, the cleaning of agate balls consumes a significant amount of manpower and time, leading to a substantial reduction in the efficiency of the entire sample preparation process. Furthermore, the cleanliness of manual cleaning depends on the operator's experience and sense of responsibility; incomplete cleaning can cause cross-contamination of subsequent batches of samples, affecting the accuracy of test results. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an agate ball cleaning device for a planetary ball mill, so as to solve the problems of low efficiency, unstable cleaning effect and inability to meet the needs of environmental testing laboratories for large-scale, high-precision soil sample preparation.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A planetary ball mill agate ball cleaning device includes: A cleaning tank, wherein a top cover is hinged to one side of the upper part of the cleaning tank, a water inlet pipe is provided on one side of the top cover, a ring pipe is connected to one end of the water inlet pipe, and several nozzles are evenly distributed on the ring pipe, and a drain pipe is provided at the lower end of the cleaning tank. A cleaning basket, located inside the cleaning box, is used to hold the agate balls and has several perforated holes. The lifting mechanism is connected to the cleaning basket and is used to drive the cleaning basket to move back and forth inside the cleaning box.

[0007] Furthermore, the lifting mechanism includes lifting rods fixedly connected to both sides of the cleaning basket, a fixed block on one side of the lifting rod, a guide rod fixedly connected to the inner wall of the cleaning tank, and the fixed block slidably connected to the guide rod; a connecting rod is hinged to the upper end of the lifting rod, and a rotating rod is hinged to the other end of the connecting rod; a rotating shaft is fixedly connected to one end of the rotating rod, and the rotating shaft is rotatably mounted on the side wall of the cleaning tank; a first transmission gear and a second transmission gear are respectively connected to the rotating shafts on both sides. It also includes a drive mechanism, which includes a transmission box fixedly installed on the side wall of the cleaning tank. A motor is provided on one side of the transmission box, and the output shaft of the motor is rotatably connected to one of the rotating shafts. A first transmission shaft is provided inside the transmission box. A first gear and a second gear are respectively provided at both ends of the first transmission shaft. The first gear meshes with a first transmission gear. A second transmission shaft is provided on one side of the transmission box, which is perpendicular to the first transmission shaft. A third gear and a fourth gear are respectively provided at both ends of the second transmission shaft. The third gear meshes with the second gear. A third transmission shaft is also provided on one side of the transmission box, which is perpendicular to the first transmission shaft. A fifth gear and a sixth gear are respectively provided on both sides of the third transmission shaft. The fifth gear meshes with the fourth gear, and the sixth gear meshes with the second transmission gear.

[0008] Furthermore, the cleaning tank is equipped with an ultrasonic cleaner.

[0009] Furthermore, the upper cover is equipped with a drying mechanism for drying the agate balls after cleaning. The drying mechanism includes a fan installed inside the upper cover, an air inlet on the outside of the upper cover, and an air outlet on the inside of the upper cover.

[0010] Furthermore, an electric heating wire is provided on the air outlet.

[0011] Furthermore, the cleaning basket includes a side wall and a bottom wall. The lower end of the side wall is provided with a boss, the inner side of the bottom wall is provided with a retaining ring that is movably connected to the boss, and the outer side of the bottom wall is provided with several inclined blades.

[0012] Furthermore, the perforations on the side walls and bottom walls are all arranged at an angle, and their angles satisfy the following settings: for the perforations on the side walls, their axes are radially inclined to the side walls, and the height of the perforation at the outer end of the side walls is higher than the height of the perforation at the inner end of the side walls; for the perforations on the bottom walls, their axes are arranged at an angle to the plane on which the bottom walls are located.

[0013] The beneficial effects of this utility model are: (1) By setting up a lifting mechanism in the cleaning box, this utility model realizes the reciprocating lifting motion of the cleaning basket in the cleaning box, which drives the agate balls to continuously and dynamically roll, avoiding cleaning dead corners caused by local accumulation of agate balls, and improving cleaning uniformity and cleaning efficiency.

[0014] (2) The cleaning box adopts the structure of an ultrasonic cleaner. It utilizes the ultrasonic cavitation effect to penetrate the cleaning liquid and act on the agate ball, thereby achieving efficient removal of tiny adhering particles and stubborn impurities in the pores on the surface of the agate ball. This solves the problem that manual brushing cannot remove fine impurities, significantly improves the cleaning cleanliness, and meets the requirements of environmental testing laboratories for agate balls without residual pollution.

[0015] (3) The air drying mechanism realizes the hot air drying of the agate balls after cleaning. The heating function of the electric heating wire increases the hot air temperature. Combined with the lifting mechanism, it drives the agate balls to tumble, avoiding uneven drying, shortening the drying time, solving the problem of extra drying time required after manual cleaning, and improving the overall processing efficiency.

[0016] (4) By setting inclined blades and a movable connection structure between the boss and the retaining ring on the bottom wall of the cleaning basket, the bottom wall is driven to rotate around the side wall by the reverse thrust of the cleaning fluid on the blades, which drives the agate ball to rotate and roll. This forms a multi-dimensional motion synergy with the lifting mechanism, further enhancing the impurity removal effect and improving the thoroughness of the agate ball cleaning.

[0017] (5) The perforations on the side walls and bottom walls of the cleaning basket are arranged at an angle, which allows the cleaning liquid to be injected into the cleaning basket at an angle, forming a tangential force on the agate ball, driving the agate ball to roll, and enhancing the cleaning effect of the agate ball.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] like Figure 1 As shown, an agate ball cleaning device for a planetary ball mill includes a cleaning box 1, a cleaning basket 3, and a lifting mechanism 4. A top cover 11 is hinged to one side of the upper part of the cleaning box 1. A water inlet pipe 12 is provided on one side of the top cover 11. One end of the water inlet pipe 12 is connected to a ring pipe 13. Several nozzles 14 are evenly distributed on the ring pipe 13. A drain pipe 15 is provided at the lower end of the cleaning box 1.

[0028] The cleaning basket 3 is located inside the cleaning box 1 and is used to hold the agate balls. It has several perforated holes.

[0029] The lifting mechanism 4 is connected to the cleaning basket 3 and is used to drive the cleaning basket 3 to move back and forth inside the cleaning box 1 to ensure the cleaning effect of the agate balls.

[0030] like Figure 4 As shown, the lifting mechanism 4 includes lifting rods 41 fixedly connected to both sides of the cleaning basket 3. A fixing block 44 is provided on one side of the lifting rod 41. A guide rod 45 is fixedly connected to the inner wall of the cleaning box 1. The fixing block 44 is slidably connected to the guide rod 45. A connecting rod 42 is hinged to the upper end of the lifting rod 41. A rotating rod 43 is hinged to the other end of the connecting rod 42. A rotating shaft 46 is fixedly connected to one end of the rotating rod 43. The rotating shaft 46 is rotatably installed on the side wall of the cleaning box 1. A first transmission gear 47 and a second transmission gear 48 are respectively connected to the rotating shafts 46 on both sides. It also includes drive mechanism 5, such as Figure 2 , Figure 3 As shown, the drive mechanism 5 includes a transmission box 51 fixedly installed on the side wall of the cleaning tank 1. A motor 52 is provided on one side of the transmission box 51, and the output shaft of the motor 52 is rotatably connected to one of the rotating shafts 46. A first transmission shaft 53 is provided inside the transmission box 51. A first gear 531 and a second gear 532 are respectively provided at both ends of the first transmission shaft 53. The first gear 531 meshes with a first transmission gear 47. A second transmission shaft 54 ​​is provided on one side of the transmission box 51, which is perpendicular to the first transmission shaft 53. A third gear 541 and a fourth gear 542 are respectively provided at both ends of the second transmission shaft 54. The third gear 541 meshes with the second gear 532. A third transmission shaft 55 is also provided on one side of the transmission box 51, which is perpendicular to the first transmission shaft 53. A fifth gear 551 and a sixth gear 552 are respectively provided on both sides of the third transmission shaft 55. The fifth gear 551 meshes with the fourth gear 542, and the sixth gear 552 meshes with the second transmission gear 48.

[0031] When cleaning the agate balls, the motor 52 is started. The motor 52 drives the rotating shafts 46 on both sides to rotate through gear transmission. The rotating shafts 46 drive the rotating rod 43 to rotate, and then the connecting rod 42 drives the lifting rod 41 to perform reciprocating lifting and lowering motion, so that the cleaning basket 3 circulates and rises and falls inside the cleaning box 1, ensuring the cleaning effect of the agate balls.

[0032] The cleaning tank 1 uses an ultrasonic cleaner, which enhances the cleaning effect of the agate balls and improves the cleaning efficiency of the agate balls.

[0033] like Figure 2 , Figure 5 As shown, the upper cover 11 is equipped with a drying mechanism 2 for drying the agate balls after cleaning. The drying mechanism 2 includes a fan 21 installed inside the upper cover 11. The upper cover 11 has an air inlet on the outside and an air outlet on the inside. After the agate balls are cleaned, the drain pipe 15 is opened to discharge the wastewater, and the fan 21 is started to dry the agate balls, thus improving the efficiency of the agate ball cleaning process.

[0034] like Figure 1 As shown, an electric heating wire 22 is provided on the air outlet. When the agate balls are dried, the electric heating wire 22 heats the blown air, causing the fan 21 to blow out hot air, which further improves the drying efficiency of the agate balls.

[0035] Furthermore, the cleaning basket 3 includes a side wall 31 and a bottom wall 33. The lower end of the side wall 31 is provided with a boss 32, and the inner side of the bottom wall 33 is provided with a retaining ring 34 that is movably connected to the boss 32. The outer side of the bottom wall 33 is provided with several inclined blades 35. When the cleaning basket 3 is immersed downward into the cleaning liquid, the cleaning liquid comes into contact with the blades 35 and forms a reverse thrust on the blades 35. Under the action of the reverse thrust, the inclined blades 35 drive the bottom wall 33 to rotate around the side wall 31, causing the agate ball to tumble in the cleaning basket 3, cleaning different parts of the agate ball, and ensuring the cleaning effect of the agate ball.

[0036] like Figure 6 As shown, the perforations on the side walls 31 and bottom wall 33 are all arranged at an angle, and their angles satisfy the following settings: for the perforations on the side walls 31, their axes are radially inclined to the side walls 31, and the height of the perforation at the outer end of the side walls 31 is higher than the height of the perforation at the inner end of the side walls 31; for the perforations on the bottom wall 33, their axes are arranged at an angle to the plane containing the bottom wall 33. When the cleaning basket 3 is immersed downwards in the cleaning liquid, the cleaning liquid is injected into the cleaning basket 3 along the axial direction of each perforation. The angled perforations allow the cleaning liquid to be injected into the cleaning basket 3 at an angle, thereby creating a comprehensive angled rinsing effect on the agate balls inside the cleaning basket 3.

[0037] The cleaning process of this device consists of four main stages: pre-cleaning, ultrasonic deep cleaning, rinsing, and air drying. The specific process is as follows: Pre-cleaning stage: Place the agate balls inside the cleaning basket 3, close the top cover 11, start the water inlet pipe 12 and close the drain pipe 15. The cleaning solution is evenly sprayed out through the nozzle 14 on the ring pipe 13 to preliminarily rinse the agate balls inside the cleaning basket 3 to remove larger soil particles and loose impurities attached to their surface. After the pre-rinsing procedure is completed, open the drain pipe 15 at the bottom of the cleaning tank 1 to completely discharge the wastewater containing suspended particles.

[0038] Ultrasonic deep cleaning stage: Close the drain pipe 15 and inject clean ultrapure water into the cleaning tank 1 through the water inlet pipe 12 until the agate balls in the basket are submerged. Activate the ultrasonic function of the cleaning tank 1, utilizing the high-frequency cavitation effect generated by ultrasound in the liquid to powerfully impact and peel away the agate balls at the microscopic level on the surface and crevices.

[0039] During ultrasonic operation, the drive mechanism 5 is activated synchronously. The motor 52 transmits power to the rotating shafts 46 on both sides via the gear system (first gear 531 to sixth gear 552) within the transmission box 51, driving the rotating rod 43 to rotate. This, in turn, through the transmission of the connecting rod 42 and the lifting rod 41, drives the cleaning basket 3 to perform continuous reciprocating lifting and lowering motion within the cleaning box 1. The water shear force generated during this lifting and lowering process, combined with the ultrasonic waves, creates a synergistic effect, further enhancing the cleaning performance.

[0040] As the cleaning basket 3 descends and immerses itself in the liquid, the cleaning fluid impacts the inclined blades 35 on the outer side of the bottom wall 33, generating a reverse thrust. This drives the bottom wall 33 to rotate relative to the side wall 31 via the connection structure between the retaining ring 34 and the boss 32. This rotational motion causes the agate balls inside the basket to continuously tumble, ensuring that all surfaces are fully exposed to the action of ultrasonic waves and water flow, achieving uniform cleaning without any blind spots.

[0041] Rinsing stage: After the ultrasonic deep cleaning is completed, the drain pipe 15 is opened again to discharge the ultrapure water containing the stripped dirt. With the drain pipe 15 open, the water inlet pipe 12 and the nozzle 14 are restarted to spray the agate ball with clean ultrapure water for a final rinse, washing away the trace amounts of sewage and impurities remaining on the surface of the agate ball to ensure cleanliness.

[0042] Air drying stage: After rinsing, close the water inlet pipe 12 and start the air drying mechanism 2 inside the top cover 11. The air drawn in by the fan 21 is heated by the heating wire 22 and blows out uniform hot air from the air outlet to efficiently dry the agate balls in the cleaning basket 3, remove surface moisture, avoid water stains, and significantly improve the overall cleaning efficiency.

[0043] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the scope defined by the structure of this utility model, they should all fall within the protection scope of this utility model.
