Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, specifically to an ultrasonic homogenizer for multi-metal powders. Background Technology

[0002] Multi-metal powders are commonly used raw materials in industrial manufacturing. They are usually mixed and configured according to the requirements of the application. However, metal powders have a fine particle size, and some similar metal powders are easy to stick together, making it difficult to mix them thoroughly. Therefore, ultrasonic waves are used to vibrate the metal powders, so that the powders are dispersed and fully mixed.

[0003] When mixing existing multi-metal powders, a certain proportion of the mixed liquid is usually added to them for contact reaction. However, the mixed liquid is usually added all at once, which can lead to problems such as excessively high or low concentrations in some areas, thereby reducing the uniformity of mixing and thus reducing production efficiency. To address this, an ultrasonic homogenizer for multi-metal powders is proposed. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide an ultrasonic homogenizer for multi-metal powders to solve the technical problem mentioned in the background that adding a mixture can lead to excessively high or low local concentrations.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an ultrasonic homogenizer for multi-metal powders, comprising a mixing tank, wherein a volume control component is provided on one side of the top of the mixing tank, and a scraping component is provided inside the mixing tank;

[0006] The quantity control component includes a servo motor mounted on the top of the mixing tank. A gear is fixed to the output end surface of the servo motor. A ratchet gear is provided on one side of the gear, and a rotating shaft is fixed to the center of the ratchet gear. A first pulley is fixed to the top of the rotating shaft. A belt is rotatably connected to the surface of the first pulley. A second pulley is rotatably connected to the inner wall of the belt away from the first pulley. A connecting shaft is fixed to the bottom of the second pulley. A rotating disk is fixed to the bottom of the connecting shaft. A solution storage cylinder is slidably connected to the surface of the rotating disk, and a fixed disk fixed to the inner wall of the solution storage cylinder is attached to the bottom of the rotating disk. A liquid storage tank is opened on one side of the fixed disk, and a piston cylinder is fixed inside the fixed disk. A piston rod is slidably connected to the inner wall of the piston cylinder. A return spring connected to the top of the inner wall of the piston cylinder is sleeved on the surface of the piston rod. A connecting pipe is provided on the surface of the piston cylinder. A telescopic pipe is slidably connected to the end of the connecting pipe away from the piston cylinder. A moving plate is fixed to the end of the telescopic pipe. A delivery pipe connected to the mixing tank is provided at the bottom of the solution storage cylinder.

[0007] As a preferred technical solution, a support frame is fixed to the lower end of the surface of the mixing tank, an inlet is provided at the top of the mixing tank, and an outlet is provided at the bottom of the mixing tank. An electromagnetic valve is installed on one side of the outlet.

[0008] As a preferred technical solution, an L-shaped connecting block is fixed to one side of the surface of the solution storage cylinder, and the L-shaped connecting block is fixed to the mixing tank.

[0009] As a preferred technical solution, the rotating disk has a circular hole, and a stop block is fixed at the bottom of the rotating disk. The fixed disk has a circular groove at the top, and the stop block is inside the circular groove and cooperates with the top of the piston rod.

[0010] As a preferred technical solution, the movable plate is provided with sliders that are slidably connected to the fixed plate at both the front and rear ends, and the movable plate covers the liquid storage tank.

[0011] As a preferred technical solution, the scraping assembly includes a vertical shaft fixedly connected to the output end of a servo motor. The upper and lower ends of the vertical shaft are fixed with first circular sleeves. Three sets of horizontal blocks are fixed on the surface of the first circular sleeves.

A helical spring installed inside the horizontal block is provided on one side of the slide rod, and a scraper that fits against the inner wall of the mixing tank is provided on the side of the slide rod away from the horizontal block. Multiple sets of ball bearings are arranged longitudinally on the inner wall of the mixing tank.

[0012] As a preferred technical solution, a second sleeve fixed to the surface of the vertical shaft is provided between the two sets of first sleeves. A stirring rod is installed on the surface of the second sleeve, and an ultrasonic amplitude transformer is installed on the stirring rod. An auger located at the discharge port is fixed at the bottom end of the vertical shaft.

[0013] In summary, the present invention has the following main advantages:

At the same time, the scraper rotates against the inner wall of the mixing tank, which can effectively clean the metal powder adsorbed on the inner wall of the mixing tank, preventing the workers from having difficulty cleaning it later. When the scraper rotates and contacts the ball bearing, it will generate a certain vibration, which can effectively shake off the metal powder remaining on the scraper, further improving the cleaning effect and enhancing the mixing efficiency. The rotation of the vertical shaft auger can effectively transport the metal powder. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] The embodiments of this utility model will be described below based on its overall structure.

[0027] An ultrasonic homogenizer for multi-metal powders, such as Figure 1-6 As shown, it includes a mixing tank 100, a volume control component 200 is provided on one side of the top of the mixing tank 100, and a scraping component 300 is provided inside the mixing tank 100;

[0028] The volume control component 200 includes a servo motor 210 mounted on the top of the mixing tank 100. A gear 220 is fixed to the output end surface of the servo motor 210. A ratchet 230 meshes with the gear 220 on one side. A rotating shaft 240 is fixed to the center of the ratchet 230. A first pulley 250 is fixed to the top of the rotating shaft 240. A belt 260 is rotatably connected to the surface of the first pulley 250. A second pulley 270 is rotatably connected to the inner wall of the belt 260 away from the first pulley 250. A connecting shaft 280 is fixed to the bottom of the second pulley 270. A rotating disk 290 is fixed to the bottom of the connecting shaft 280. A solution storage cylinder 2910 is slidably connected to the surface of the rotating disk 290. A fixed disk 2920 fixed to the inner wall of the solution storage cylinder 2910 is attached to the bottom of the rotating disk 290. A liquid storage opening is provided on one side of the fixed disk 2920. The groove 2921 and the fixed plate 2920 have a piston cylinder 2930 fixed inside. The piston rod 2940 is slidably connected to the inner wall of the piston cylinder 2930. The piston rod 2940 is fitted with a return spring 2950 connected to the top of the inner wall of the piston cylinder 2930. The piston cylinder 2930 has a connecting pipe 2960. The end of the connecting pipe 2960 away from the piston cylinder 2930 is slidably connected to a telescopic pipe 2970. The end of the telescopic pipe 2970 is fixed with a moving plate 2980. The bottom of the solution storage cylinder 2910 has a conveying pipe 2990 connected to the mixing tank 100. The rotating plate 290 has a round hole 291. The bottom of the rotating plate 290 has an abutment block 2941. The top of the fixed plate 2920 has a round groove 2922. The abutment block 2941 is inside the round groove 2922 and cooperates with the top of the piston rod 2940.

[0029] During the metal powder mixing process, the reverse servo motor 210 causes the gear 220 to rotate, which in turn drives the ratchet 230 to rotate synchronously. The ratchet 230 drives the first pulley 250 and belt 260 to rotate via the rotating shaft 240. The belt 260 drives the second pulley 270 and connecting shaft 280 to rotate, which in turn drives the rotating disk 290 to rotate synchronously. When the circular hole 291 inside the rotating disk 290 rotates to be directly above the liquid storage tank 2921, the mixed liquid in the solution storage cylinder 2910 will flow into the liquid storage tank 2921 through the circular hole 291. The continuous rotation of the rotating disk 290 will drive the circular hole 291 to move to one side, and at the same time drive the abutment block 2941 to move inside the circular groove 2922. When the contact block 2941 comes into contact with the piston rod 2940, it will compress the piston rod 2940, causing the piston rod 2940 to stretch the return spring 2950 and compress the gas inside the piston cylinder 2930. The gas enters the connecting pipe 2960, and under the action of air pressure, the telescopic pipe 2970 moves out, which drives the moving plate 2980 to move. This allows the mixture inside the liquid storage tank 2921 to flow into the mixing tank 100 through the conveying pipe 2990. By intermittently adding the mixture in a quantitative manner, it is possible to ensure that the metal powder can fully contact and react with the mixture, avoiding the problem of excessively high or low local concentration caused by adding it all at once. This improves the uniformity of mixing, reduces waste and unnecessary losses, and thus improves production efficiency. At the same time, it can precisely control the reaction rate, avoiding the reaction being too violent or too slow, which is conducive to the smooth progress of the reaction and the quality control of the product.

[0030] Please refer to this carefully. Figure 1 A support frame 110 is fixed to the lower end of the surface of the mixing tank 100. The top of the mixing tank 100 is provided with a feed port 120 and the bottom of the mixing tank 100 is provided with a discharge port 130. A solenoid valve 131 is installed on one side of the discharge port 130. An L-shaped connecting block 2911 is fixed to one side of the surface of the solution storage cylinder 2910. The L-shaped connecting block 2911 is fixed to the mixing tank 100.

[0031] The multi-metal powder is mixed by feeding it into the mixing tank 100 through the feed port 120, and the stability of the overall equipment is enhanced by the support frame 110.

[0032] Please refer to this carefully. Figures 3 to 5 The movable plate 2980 has sliders 2981 that are slidably connected to the fixed plate 2920 at both the front and rear ends, and the movable plate 2980 covers the liquid storage tank 2921.

[0033] By setting the slider 2981, the moving plate 2980 can be made more stable when sliding inside the fixed plate 2920.

[0034] Please refer to this carefully. Figure 2 and Figure 6 The scraping assembly 300 includes a vertical shaft 310 fixedly connected to the output end of the servo motor 210. The upper and lower ends of the vertical shaft 310 are fixed with first sleeves 320. Three sets of horizontal blocks 330 are fixed on the surface of the first sleeves 320. A slide rod 350 is slidably connected to the inner wall of the horizontal block 330. A spiral spring 340 installed inside the horizontal block 330 is provided on one side of the slide rod 350. A scraper 360 is attached to the inner wall of the mixing tank 100 on the side of the slide rod 350 away from the horizontal block 330. Multiple sets of ball bearings 361 are arranged longitudinally on the inner wall of the mixing tank 100. A second sleeve 370 is fixed to the surface of the vertical shaft 310 between the two sets of first sleeves 320. A stirring rod 380 is installed on the surface of the second sleeve 370. An ultrasonic amplitude transformer 390 is installed on the stirring rod 380. An auger 3910 located at the discharge port 130 is fixed at the bottom end of the vertical shaft 310.

[0035] When the metal powder is inside the mixing tank 100, the servo motor 210 is activated, driving the vertical shaft 310 to rotate. The vertical shaft 310, through the second sleeve 370, drives the stirring rod 380 to mix the metal powder inside the mixing tank 100. Simultaneously, the vertical shaft 310, through the first sleeve 320, drives the horizontal block 330 to rotate synchronously. This causes the horizontal block 330 to drive the sliding rod 350 and scraper 360 to rotate against the inner wall of the mixing tank 100, effectively cleaning the metal powder adsorbed on the inner wall of the mixing tank 100 and preventing subsequent damage by workers. While facilitating cleaning, when the scraper 360 rotates and contacts the ball bearing 361, the scraper 360 drives the slide bar 350 to squeeze the spiral spring 340 and move inward. When it disengages from the ball bearing 361, the slide bar 350 will reset under the reaction force of the spiral spring 340 and generate a certain vibration, which can effectively shake off the residual metal powder on the scraper 360, further improving the cleaning effect and enhancing the mixing efficiency. After the processing and mixing are completed, the rotation of the auger 3910 driven by the vertical shaft 310 can effectively transport the metal powder.

[0036] In use, the servo motor 210 is activated to cause the stirring rod 380 to mix the metal powder inside the mixing tank 100. Simultaneously, the scraper 360 rotates against the inner wall of the mixing tank 100, effectively cleaning the metal powder adsorbed on the inner wall and preventing subsequent cleaning difficulties for personnel. When the scraper 360 rotates and contacts the ball bearing 361, it generates vibration, effectively shaking off any residual metal powder on the scraper 360, further improving the cleaning effect and enhancing mixing efficiency. The rotation of the vertical shaft auger 3910 effectively conveys the metal powder during the mixing process. The reverse servo motor 210 causes the mixture inside the liquid storage tank 2921 to flow into the mixing tank 100 through the delivery pipe 2990. By intermittently adding the mixture in a quantitative manner, it is ensured that the metal powder can fully contact and react with the mixture, avoiding the problem of excessively high or low local concentration caused by adding it all at once. This improves the uniformity of mixing, reduces waste and unnecessary losses, and thus improves production efficiency. At the same time, it can precisely control the reaction rate, avoiding the reaction being too vigorous or too slow, which is conducive to the smooth progress of the reaction and the quality control of the product. All parts not mentioned in this device are the same as or can be implemented using existing technologies.
