Technical Field
[0001] This utility model belongs to the field of metal powder drying technology, specifically relating to metal powder drying equipment with a scraping device. Background Technology
[0002] In most existing drying equipment, drying metal powder (a group of metal particles smaller than 1 mm, including single metal powder, alloy powder, and certain refractory compound powders with metallic properties) involves dispersing the extruded metal powder by rotating a shaft. However, during this dispersing process, due to the moisture content in the metal powder, some of the dispersed metal powder adheres to the inner wall of the equipment, preventing it from falling down and being discharged, thus wasting raw materials. To address this issue, a metal powder drying equipment with a scraping device is proposed. Summary of the Invention
[0003] The purpose of this invention is to provide a metal powder drying device with a scraping device, which solves the problem in the prior art where metal powder adheres to the inner wall of the drying device during drying, resulting in waste of raw materials.
[0004] The technical solution adopted by this utility model is a metal powder drying equipment with a scraping device, including a tank. The tank adopts a double-layer structure. A discharge pipe is fixedly connected to the bottom of the tank, and a feed hopper is fixedly connected to the top of the tank. A connecting pipe is also fixedly connected to the upper surface of the tank. A rotating rod is vertically arranged inside the tank. Several connecting rods are evenly fixedly connected to the rotating rod. One end of the connecting rod is fixedly perpendicular to the rotating rod. A scraper is fixedly connected to the end of the connecting rod away from the rotating rod. The surface of the scraper is in contact with the inner wall of the tank. A motor is also fixedly connected to the surface of the tank. The output end of the motor is connected to the rotating rod.
[0005] The feature of this utility model is that,
[0006] The tank has several baffles evenly spaced from top to bottom inside. The sides of the baffles are fixedly connected to the inner wall of the tank. Scrapers are spaced apart from the baffles. The surface of the baffles is concave and conical, and a groove is opened at the center of the baffle. The rotating rod passes through the groove and is fixedly connected to the connecting rod. A heating wire is installed inside the baffle, and the heating wire is connected to an external power source.
[0007] The rotating rod located at the groove position is vertically fixed to the circumferential surface with equally spaced dispersing blades, the length of which matches the radius of the groove.
[0008] A fixed rod is inclined to the surface of the scraper. The inclination angle of the fixed rod is the same as the concave angle of the baffle. A crushing rod is rotatably connected to the fixed rod, and the surface of the crushing rod is in contact with the surface of the baffle.
[0009] The baffle has several sliding rods arranged in a circular pattern arranged vertically inside. One end of the sliding rod inside the baffle is fixedly connected to an impact plate. The surface of the impact plate is slidably connected to the inside of the baffle. One end of the sliding rod outside the baffle is fixedly connected to a fixing block. The fixing block has a wedge-shaped structure. A spring is sleeved on the sliding rod. One end of the spring is fixedly connected to the impact plate. A toggle rod is also vertically arranged at the position of the rotating rod corresponding to the fixing block.
[0010] The top of the tank has a rotating disk and a fixed disk arranged from top to bottom. The output end of the motor is fixedly connected to the rotating disk. The lower end of the feed hopper is in contact with the upper surface of the rotating disk. The surface of the rotating disk slides against the inner wall of the tank. The side circumference of the fixed disk is fixedly connected to the inner wall of the tank. The output end of the motor passes through the fixed disk and is connected to the rotating rod. The surface of the fixed disk is in contact with the bottom of the rotating disk. The surface of the rotating disk has through holes arranged equidistantly in a circle. The surface of the fixed disk also has through holes arranged equidistantly in a circle. The diameter of the through holes on the fixed disk is at most one-quarter of the diameter of the through holes on the rotating disk.
[0011] A spiral tube is wound between the two layers of the tank body. One end of the spiral tube is connected to a connecting pipe that is fixedly connected to the surface of the tank body, and the other end of the spiral tube is connected to an air inlet pipe that is fixedly connected to the tank body.
[0012] The beneficial effects of this invention are that the metal powder drying equipment with a scraping device, by starting the motor, causes the scraper to scrape off the metal powder adhering to the inner wall of the tank, thus avoiding the situation where the metal powder adheres to the inner wall of the tank and thereby avoiding the waste of metal powder. The metal powder drying equipment with a scraping device, through the arrangement of multiple sets of dispersing blades and baffles, ensures that when the metal powder falls from the surface of one baffle, it is further dispersed by the rotating dispersing blades below, thereby achieving the purpose of multiple dispersing of the metal powder. At the same time, the multiple sets of baffles block the falling metal powder, preventing it from falling directly to the bottom of the tank, further improving the dispersing effect of the metal powder. Metal powder drying equipment with a scraping device, through the arrangement of a fixed disc, a rotating disc, and through holes, prevents metal powder from consistently falling to one position on the baffle, thereby improving the uniformity of metal powder feeding in the tank. This allows the metal powder to be more evenly distributed on the baffle, ensuring that the heating wires in the baffle can heat and dry the metal powder evenly. This reduces ineffective heating of the heating wires during the device's operation, thus improving the utilization rate of the heating wires' heating effect. At the same time, the dispersed feeding of metal powder further improves the heating and drying efficiency of the metal powder, thereby enhancing the device's performance and making it worthy of promotion.

[0028] Example 1
[0029] This utility model relates to a metal powder drying device with a scraping mechanism, the structure of which is as follows: Figure 1 , Figure 2 As shown, the device includes a tank 1, which has a double-layer structure. A discharge pipe 2 is fixedly connected to the bottom of the tank 1, and a feed hopper 3 is fixedly connected to the top of the tank 1. A connecting pipe 4 is also fixedly connected to the upper surface of the tank 1. A rotating rod 6 is vertically arranged inside the tank 1.

[0030] When motor 5 starts, the output end of motor 5 drives rotating rod 6 to rotate, rotating rod 6 drives connecting rod 8 to rotate, connecting rod 8 drives scraper 9 to rotate, so scraper 9 scrapes the inner wall of tank 1. By starting motor 5, scraper 9 scrapes off the metal powder adhering to the inner wall of tank 1, avoiding the situation where metal powder adheres to the inner wall of tank 1, thus avoiding the waste of metal powder.
[0031] Example 2
[0032] This utility model relates to a metal powder drying device with a scraping mechanism, the structure of which is as follows: Figure 1 , Figure 2 As shown, the device includes a tank 1, which has a double-layer structure. A discharge pipe 2 is fixedly connected to the bottom of the tank 1, and a feed hopper 3 is fixedly connected to the top of the tank 1. A connecting pipe 4 is also fixedly connected to the upper surface of the tank 1. A rotating rod 6 is vertically arranged inside the tank 1. Several connecting rods 8 are evenly fixedly connected to the rotating rod 6. One end of the connecting rod 8 is fixedly perpendicular to the rotating rod 6. A scraper 9 is fixedly connected to the end of the connecting rod 8 away from the rotating rod 6. The surface of the scraper 9 is in contact with the inner wall of the tank 1. A motor 5 is also fixedly connected to the surface of the tank 1. The output end of the motor 5 is connected to the rotating rod 6.
[0033] like Figure 3 As shown, several baffles 12 are evenly spaced from top to bottom inside the tank 1. The sides of the baffles 12 are fixedly connected to the inner wall of the tank 1. The scraper 9 is spaced apart from the baffles 12. The surface of the baffles 12 is concave and conical. A groove 13 is provided at the center of the baffles 12. The rotating rod 6 passes through the groove 13 and is fixedly connected to the connecting rod 8. A heating wire 19 is provided inside the baffles 12.

[0034] Combination Figure 4 The rotating rod 6 located at the groove 13 is vertically fixedly connected with equidistantly arranged dispersing blades 7 along the circumferential surface, and the length of the dispersing blades 7 matches the radius of the groove 13.
[0035] When the rotating rod 6 rotates, it drives the dispersing blades 7 to rotate. The dispersing blades 7 disperse the metal powder that falls onto their surface. With the arrangement of multiple sets of dispersing blades 7 and baffles 12, when the metal powder falls from the surface of a baffle 12, it will be dispersed again by the rotating dispersing blades 7 below, thus achieving the purpose of dispersing the metal powder multiple times. At the same time, the arrangement of multiple sets of baffles 12 blocks the falling metal powder, preventing the metal powder from falling directly to the bottom of the tank 1, further improving the dispersing effect of the metal powder.
[0036] Example 3
[0037] This utility model relates to a metal powder drying device with a scraping mechanism, the structure of which is as follows: Figure 1 , Figure 2 As shown, the device includes a tank 1, which has a double-layer structure. A discharge pipe 2 is fixedly connected to the bottom of the tank 1, and a feed hopper 3 is fixedly connected to the top of the tank 1. A connecting pipe 4 is also fixedly connected to the upper surface of the tank 1. A rotating rod 6 is vertically arranged inside the tank 1. Several connecting rods 8 are evenly fixedly connected to the rotating rod 6. One end of the connecting rod 8 is fixedly perpendicular to the rotating rod 6. A scraper 9 is fixedly connected to the end of the connecting rod 8 away from the rotating rod 6. The surface of the scraper 9 is in contact with the inner wall of the tank 1. A motor 5 is also fixedly connected to the surface of the tank 1. The output end of the motor 5 is connected to the rotating rod 6.
[0038] like Figure 3 As shown, several baffles 12 are evenly spaced from top to bottom inside the tank 1. The sides of the baffles 12 are fixedly connected to the inner wall of the tank 1. The scraper 9 is spaced apart from the baffles 12. The surface of the baffles 12 is concave and conical. A groove 13 is provided at the center of the baffles 12. The rotating rod 6 passes through the groove 13 and is fixedly connected to the connecting rod 8. A heating wire 19 is provided inside the baffles 12. The heating wire 19 is connected to an external power source.
[0039] Combination Figure 4 The rotating rod 6 located at the groove 13 is vertically fixedly connected with equidistantly arranged dispersing blades 7 along the circumferential surface, and the length of the dispersing blades 7 matches the radius of the groove 13.
[0040] A fixed rod 10 is inclinedly connected to the surface of the scraper 9. The inclination angle of the fixed rod 10 is consistent with the concave angle of the baffle 12. A crushing rod 11 is rotatably connected to the fixed rod 10. The surface of the crushing rod 11 is in contact with the surface of the baffle 12.
[0041] When the scraper 9 moves, the scraper 9 drives the fixed rod 10 to move, and the fixed rod 10 drives the crushing rod 11 to move. The movement of the crushing rod 11 further disperses the metal powder that has been splashed on the surface of the baffle 12, thereby further dispersing the metal powder.
[0042] Example 4
[0043] This utility model relates to a metal powder drying device with a scraping mechanism, the structure of which is as follows: Figure 1 , Figure 2 As shown, the device includes a tank 1, which has a double-layer structure. A discharge pipe 2 is fixedly connected to the bottom of the tank 1, and a feed hopper 3 is fixedly connected to the top of the tank 1. A connecting pipe 4 is also fixedly connected to the upper surface of the tank 1. A rotating rod 6 is vertically arranged inside the tank 1. Several connecting rods 8 are evenly fixedly connected to the rotating rod 6. One end of the connecting rod 8 is fixedly perpendicular to the rotating rod 6. A scraper 9 is fixedly connected to the end of the connecting rod 8 away from the rotating rod 6. The surface of the scraper 9 is in contact with the inner wall of the tank 1. A motor 5 is also fixedly connected to the surface of the tank 1. The output end of the motor 5 is connected to the rotating rod 6.
[0044] Combination Figure 4 The rotating rod 6 located at the groove 13 is vertically fixedly connected with equidistantly arranged dispersing blades 7 along the circumferential surface, and the length of the dispersing blades 7 matches the radius of the groove 13.
[0045] A fixed rod 10 is inclinedly connected to the surface of the scraper 9. The inclination angle of the fixed rod 10 is consistent with the concave angle of the baffle 12. A crushing rod 11 is rotatably connected to the fixed rod 10. The surface of the crushing rod 11 is in contact with the surface of the baffle 12.
[0046] The baffle 12 has several sliding rods 15 arranged in a circular pattern vertically inside. One end of the sliding rod 15 inside the baffle 12 is fixedly connected to an impact plate 18. The surface of the impact plate 18 is slidably connected to the inside of the baffle 12. One end of the sliding rod 15 outside the baffle 12 is fixedly connected to a fixing block 17. The fixing block 17 has a wedge-shaped structure. A spring 16 is sleeved on the sliding rod 15. One end of the spring 16 is fixedly connected to the impact plate 18. A toggle rod 14 is also vertically arranged at the position of the rotating rod 6 corresponding to the fixed block 17.
[0047] When the rotating rod 6 rotates, it drives the actuating rod 14 to rotate. The rotating actuating rod 14 presses against the inclined surface of the fixed block 17. The fixed block 17 is forced to slide the sliding rod 15 downward. The sliding rod 15 drives the impact plate 18 to slide. The sliding impact plate 18 presses against the spring 16. So when the actuating rod 14 separates from the fixed block 17, under the elastic force of the spring 16, the sliding rod 15 drives the fixed block 17 to slide upward. This causes the sliding rod 15 to push the impact plate 18. The impact plate 18 impacts the baffle 12, causing the baffle 12 to vibrate. This vibrates the metal powder on the surface of the baffle 12, causing the metal powder to slide down the conical surface of the baffle 12 and be dispersed by the dispersing blade 7, thus preventing the metal powder from accumulating on the surface of the baffle 12.
[0048] Example 5
[0049] This utility model relates to a metal powder drying device with a scraping mechanism, the structure of which is as follows: Figure 1 , Figure 2 As shown, the device includes a tank 1, which has a double-layer structure. A discharge pipe 2 is fixedly connected to the bottom of the tank 1, and a feed hopper 3 is fixedly connected to the top of the tank 1. A connecting pipe 4 is also fixedly connected to the upper surface of the tank 1. A rotating rod 6 is vertically arranged inside the tank 1. Several connecting rods 8 are evenly fixedly connected to the rotating rod 6. One end of the connecting rod 8 is fixedly perpendicular to the rotating rod 6. A scraper 9 is fixedly connected to the end of the connecting rod 8 away from the rotating rod 6. The surface of the scraper 9 is in contact with the inner wall of the tank 1. A motor 5 is also fixedly connected to the surface of the tank 1. The output end of the motor 5 is connected to the rotating rod 6.
[0050] like Figure 3 As shown, several baffles 12 are evenly spaced from top to bottom inside the tank 1. The sides of the baffles 12 are fixedly connected to the inner wall of the tank 1. Scrapers 9 are spaced apart from the baffles 12. The surface of the baffles 12 is concave and conical, and a groove 13 is formed at the center of the baffle 12. The rotating rod 6 passes through the groove 13 and is fixedly connected to the connecting rod 8. A heating wire 19 is installed inside the baffle 12, and the heating wire 19 is connected to an external power source. Heat is released for heating, which is a known existing device.
[0051] The heating wire 19 heats the inside of the tank 1, bringing it to a suitable temperature for drying the metal powder. Meanwhile, after the metal powder enters the tank 1 through the feed hopper 3, it is dispersed by the dispersing blades 7, causing some of the metal powder to splash onto the surface of the baffle 12, where it is heated and dried again, further enhancing the drying effect.
[0052] Example 6
[0053] A rotating disk 20 is fixedly connected to the output end of motor 5. The lower end of the feed hopper 3 is in contact with the surface of the rotating disk 20. The surface of the rotating disk 20 slides against the inner wall of the tank 1. A fixed disk 21 is fixedly connected to the inner wall of the tank 1. The output end of motor 5 passes through the surface of the fixed disk 21 and is rotatably connected to the interior of the fixed disk 21. The surface of the fixed disk 21 is in contact with the bottom of the rotating disk 20. The surface of the rotating disk 20 is provided with through holes 22 arranged equidistantly in a circle. The surface of the fixed disk 21 is also provided with through holes 22 arranged equidistantly in a circle. 2. The diameter of the through hole 22 on the fixed disk 21 is at most one-quarter of the diameter of the through hole 22 on the rotating disk 20. This ensures that when the through hole 22 on the rotating disk 20 coincides with the through hole 22 on the fixed disk 21, the material in the through hole 22 on the rotating disk 20 will not be discharged all at once. Therefore, when the motor 5 starts, it drives the rotating disk 20 to rotate, causing the through hole 22 on the rotating disk 20 to gradually coincide with the lower end of the feed hopper 3. This allows the material in the feed hopper 3 to fall into the through hole 22 on the rotating disk 20. Simultaneously, due to the lower fixed disk 21... By blocking the through holes 22 on the rotating disk 20, the metal powder will not fall directly onto the baffle 12. As the rotating disk 20 rotates, the through holes 22 on the rotating disk 20 gradually overlap with the through holes 22 on the fixed disk 21. The metal powder stored in the through holes 22 on the rotating disk 20 then falls downwards through the through holes 22 on the fixed disk 21 and onto the baffle 12. Because the material in the through holes 22 on the rotating disk 20 will not be discharged through the through holes 22 on the fixed disk 21 all at once, the metal powder will not always fall onto a single position on the baffle 12. This improves the uniformity of the metal powder feeding in the tank 1, allowing the metal powder to be more evenly distributed on the baffle 12. This ensures that the heating wires 19 in the baffle 12 can heat and dry the metal powder, reducing ineffective heating of the heating wires 19 during device use and improving the utilization rate of the heating effect of the heating wires 19. Furthermore, the dispersed feeding of the metal powder further improves the heating and drying efficiency of the metal powder, thus enhancing the overall effectiveness of the device and making it worthy of promotion.
[0054] Example 7
[0055] A connecting pipe 4 is fixedly connected to the surface of the tank body 1. The end of the connecting pipe 4 away from the tank body 1 is connected to an external air pump. An air inlet pipe 24 is fixedly connected to the inside of the tank body 1. A spiral tube 23 is also fixedly connected to the inside of the tank body 1. The two ends of the spiral tube 23 are fixedly connected to the air inlet pipe 24 and the connecting pipe 4, respectively. This allows the hot air generated during the metal powder production process to be introduced into the spiral tube 23 through the air inlet pipe 24. By utilizing the hot air generated in other processes during metal powder processing, such as the hot air generated when metal materials are melted, it works in conjunction with the heating wire 19 to heat and dry the metal powder, thereby reducing energy consumption during the use of the device and improving the energy-saving effect of the device.
[0056] Working principle: When motor 5 starts, the output end of motor 5 drives rotating rod 6 to rotate, rotating rod 6 drives connecting rod 8 to rotate, connecting rod 8 drives scraper 9 to rotate, thus scraping the inner wall of tank 1. At the same time, when rotating rod 6 rotates, rotating rod 6 drives toggle rod 14 to rotate, toggle rod 14 rotates and squeezes the inclined surface of fixed block 17. Fixed block 17 is forced to slide sliding rod 15 downward, sliding rod 15 drives impact plate 18 to slide, impact plate 18 slides and squeezes spring 16. Thus, when toggle rod 14 separates from fixed block 17, under the elastic force of spring 16, sliding rod 15 drives fixed block 17 to slide upward, thus making sliding rod 15 push impact plate 18, impact plate 18 impacts baffle 12, causing baffle 12 to vibrate, vibrating the metal powder on the surface of baffle 12.
