Abstract
Description
Technical Field
[0001] This utility model relates to the field of diamond micron powder processing technology, specifically to a diamond micron powder drying device with multiple drying cycles. Background Technology
[0002] Diamond micron powder is a new type of superhard and ultrafine abrasive formed by processing synthetic diamond single crystals through special processes. It is an ideal raw material for grinding and polishing high-hardness materials such as cemented carbide, ceramics, gemstones, and optical glass. Diamond products are tools and components made from diamond materials and have a wide range of applications. Diamond micron powder and its products are widely used in the automotive, machinery, electronics, aviation, aerospace, optical instruments, glass, ceramics, petroleum, and geological industries. Diamond micron powder must be dried before storage to remove moisture from it.
[0003] However, existing drying devices often cause diamond micropowder to clump together during drying, resulting in long drying times and incomplete drying. Furthermore, during the drying process, water vapor condenses upwards and drips into the drying chamber, causing water droplets inside the chamber to fall onto the diamond micropowder, leading to clumping and affecting the drying effect. In addition, existing drying devices often perform only a single drying cycle, resulting in limited drying efficiency.
[0004] Based on this, a diamond micro powder drying device with multiple drying cycles is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Example 1
[0024] In one embodiment, such as Figures 1-5As shown, a diamond micro powder drying device with multiple drying cycles includes a drying chamber 11. A feed pipe 12 is connected to the drying chamber 11. Two guide plates 13 are positioned inside the drying chamber 11 corresponding to one end of the feed pipe 12. A sealing pipe 14 is attached to one end of each guide plate 13 and is fixedly installed inside the drying chamber 11. A distributing roller 15 rotates inside the sealing pipe 14, and the distributing roller 15 has a circular array of several material-collecting grooves. A first drying plate 20, a second drying plate 21, and a third drying plate are positioned inside the drying chamber 11 below the outlet of the sealing pipe 14. 22. Heating components 23 are fixedly installed inside the first drying plate 20, the second drying plate 21 and the third drying plate 22. The bottom end of the guide plate 13 is provided with an adjustment component for adjusting the working angle of the first drying plate 20, the second drying plate 21 and the third drying plate 22. A conveying mechanism for circulating and conveying diamond powder is provided on one side of the drying box 11. An exhaust mechanism for venting is provided inside the drying box 11. The conveying mechanism facilitates the circulating and conveying of diamond powder at the bottom of the drying box 11, allowing for multiple drying cycles. The exhaust mechanism facilitates the discharge of gas inside the drying box 11, thereby preventing steam condensation.
[0025] The adjusting assembly includes a second connecting rod 38. First hinge seats are symmetrically provided at the upper ends of the first drying plate 20, the second drying plate 21, and the third drying plate 22. Second hinge seats are symmetrically provided at the bottom ends of the first drying plate 20 and the second drying plate 21. The second hinge seats at the bottom of the first drying plate 20 and the first hinge seats at the upper ends of the second drying plate 21 are hinged together by the second connecting rod 38. The second hinge seats at the bottom of the second drying plate 21 and the first hinge seats at the upper ends of the third drying plate 22 are also hinged together by the second connecting rod 38. The first drying plate 20, the second drying plate 21, and the third drying plate 22 are all rotatably mounted on the drying plate. Inside the drying chamber 11, a third connecting rod is hinged to the first hinge seat at the upper end of the first drying plate 20. A fixed rod is fixed between the two third connecting rods. A rotating block is rotatably mounted on the fixed rod. The rotating block is fixed to the output end of the second electric push rod 24. The second electric push rod 24 is hinged to the bottom end of the guide plate 13. One end of the distributing roller 15 is fixedly connected to the output end of the first motor 16. The first motor 16 is fixedly mounted on one side of the drying chamber 11. In use, when it is necessary to dry diamond powder, diamond powder is added into the drying chamber 11 through the feed pipe 12. The micro powder accumulates on the upper ends of the two guide plates 13. Then, the first motor 16 is started, driving the distributing roller 15 to rotate. When the feeding trough on the distributing roller 15 rotates to the position between one end of the two guide plates 13, a fixed amount of diamond micro powder is loaded into the feeding trough. Afterward, the feeding trough rotates above the first drying plate 20, and the diamond micro powder falls onto the upper end of the first drying plate 20. At this time, the heating component 23 is activated, heating the upper ends of the first drying plate 20, the second drying plate 21, and the third drying plate 22. Because the first drying plate 20, the second drying plate 21, and the third drying plate 22 are all inclined, the diamond micro powder... The diamond powder passes through the upper ends of the first drying plate 20, the second drying plate 21, and the third drying plate 22 one by one to dry the diamond micro powder. When it is necessary to adjust the drying time of the diamond micro powder, the second electric push rod 24 is activated. The output end of the second electric push rod 24 drives the first drying plate 20 to rotate. Since the first drying plate 20, the second drying plate 21, and the third drying plate 22 are all connected by the second connecting rod 38, the second drying plate 21 and the third drying plate 22 rotate synchronously, thereby adjusting the tilt angle of the first drying plate 20, the second drying plate 21, and the third drying plate 22, and thus adjusting the residence time of the diamond micro powder.
[0026] The conveying mechanism includes a conveying pipe 25, which is fixedly mounted on one side of the drying chamber 11. An installation shaft is rotatably mounted inside the conveying pipe 25, and a spiral plate 26 is fixedly mounted on the installation shaft. One end of the installation shaft is fixedly connected to the output end of a second motor 27, which is fixedly mounted at the bottom end of the conveying pipe 25. One end of the conveying pipe 25 is connected to a first discharge pipe 28 and a second discharge pipe 30. A first baffle 29 and a second baffle 31 are slidably mounted on the first discharge pipe 28 and the second discharge pipe 30, respectively. Both the first baffle 29 and the second baffle 31 are fixedly mounted on a connecting plate, which is fixedly mounted on the output end of a third electric push rod 32. The third electric push rod 32 is fixedly mounted on one side of the drying chamber 11. One end of the first discharge pipe 28 extends above the first drying plate 20. When the diamond powder is dried, it falls to the bottom of the drying chamber 11 for storage. If the diamond powder needs to be dried repeatedly, the second motor 27 is started. The second motor 27 drives the mounting shaft to rotate, and the mounting shaft drives the spiral plate 26 to rotate. The spiral plate 26 works in conjunction with the transmission pipe 25 to transport the diamond powder at the bottom of the drying chamber 11. After the diamond powder is transported to one end of the transmission pipe 25, it falls through the first discharge pipe 28 to the top of the first drying plate 20 for repeated drying. When the diamond powder needs to be discharged, the third electric push rod 32 is started. The output end of the third electric push rod 32 drives the first baffle 29 and the second baffle 31 to move, so that one end of the first discharge pipe 28 is closed and one end of the second discharge pipe 30 is opened, thereby discharging the diamond powder at the bottom of the drying chamber 11.
[0027] The exhaust mechanism includes a partition plate 36, which is fixedly installed inside the drying chamber 11. The partition plate 36 is positioned above the guide plate 13. The upper end of the partition plate 36 and the upper end of the interior of the drying chamber 11 form an exhaust chamber. An exhaust pipe 35 is connected inside the exhaust chamber. One end of the exhaust pipe 35 is in close contact with the upper end of the guide plate 13. An air inlet is provided at the position corresponding to one end of the exhaust pipe 35 on the upper end of the guide plate 13. A filter plate 37 is slidably installed inside the exhaust chamber. A connecting pipe is connected inside the exhaust chamber. One end of the connecting pipe extends to the outside of the drying chamber 11. In use, when the water vapor inside the diamond powder is evaporated, the hot air will move upward, causing the hot air to enter the exhaust chamber through the exhaust pipe 35. After being filtered by the filter plate 37, the hot air is discharged through the connecting pipe.
[0028] An air inlet pipe 33 is fixedly installed inside the drying chamber 11. The air inlet pipe 33 is located above one end of the third drying plate 22. Several air outlet holes are provided on one side of the air inlet pipe 33. The input end of the air inlet pipe 33 is connected to the output end of the hot air blower 34. The hot air blower 34 is fixedly installed on one side of the drying chamber 11. When drying diamond micro powder, the hot air blower 34 generates hot air and delivers it into the air inlet pipe 33. The air inlet pipe 33 discharges the hot air, and the discharged hot air drives the air inside the drying chamber 11 to circulate, thereby accelerating the discharge of moisture. It is worth noting that the hot air blower 34 in this application uses existing components, which will not be described in detail here.
[0029] The drying oven 11 is provided with a cleaning port at the top, and a sealing cover is provided inside the cleaning port to facilitate the cleaning of the micro powder connected to the filter plate 37 during use. Example 2
[0030] The difference from Embodiment 1 is that: each of the feeding troughs is slidably provided with an adjusting plate 17, and each adjusting plate 17 is hinged to a first connecting rod 18 at its bottom end. The other end of each first connecting rod 18 is hinged to a sliding rod. The sliding rod is slidably disposed inside the distributing roller 15. One end of the sliding rod is rotatably provided with a rotating plate, and one end of a first electric push rod 19 is fixedly disposed on the rotating plate. The first electric push rod 19 is fixedly disposed on one side of the drying oven 11. In use, when it is necessary to adjust the capacity of the feeding trough, the first electric push rod 19 is activated. The output end of the first electric push rod 19 drives the sliding rod to move. The sliding rod drives the adjusting plate 17 to slide in the feeding trough through the first connecting rod 18, thereby adjusting the capacity of the feeding trough.
[0031] The above embodiments disclose a diamond micro powder drying device with multiple drying processes. When the diamond micro powder needs to be dried, it is added into the drying chamber 11 through the feed pipe 12. The diamond micro powder accumulates on the upper ends of the two guide plates 13. Then, the first motor 16 is started, driving the distributing roller 15 to rotate. When the feeding trough on the distributing roller 15 rotates to the position between one end of the two guide plates 13, the feeding trough is loaded with a fixed amount of diamond micro powder. Then, after the feeding trough rotates above the first drying plate 20, the diamond micro powder falls onto the upper end of the first drying plate 20. At this time, the heating component 23 is activated, heating the upper ends of the first drying plate 20, the second drying plate 21, and the third drying plate 22. Because the first drying... The first drying plate 20, the second drying plate 21, and the third drying plate 22 are all inclined, so that the diamond powder passes through the upper ends of the first drying plate 20, the second drying plate 21, and the third drying plate 22 one by one, thereby drying the diamond powder. After being dried, the diamond powder falls to the bottom of the drying box 11 for storage. If it is necessary to repeatedly dry the diamond powder, the second motor 27 is started. The second motor 27 drives the mounting shaft to rotate, and the mounting shaft drives the spiral plate 26 to rotate. The spiral plate 26 works in conjunction with the transmission pipe 25 to transfer the diamond powder at the bottom of the drying box 11. After the diamond powder is transferred to one end of the transmission pipe 25, it falls through the first discharge pipe 28 to the upper end of the first drying plate 20, thereby undergoing repeated drying.
[0032] While the diamond powder is being dried, the hot air blower 34 generates hot air and delivers it into the air inlet pipe 33. The air inlet pipe 33 discharges the hot air, which drives the air inside the drying chamber 11 to flow. The hot air will move upward, so that the hot air enters the exhaust chamber through the exhaust pipe 35. After being filtered by the filter plate 37, the hot air is discharged through the connecting pipe.
[0033] When diamond powder needs to be discharged, the third electric push rod 32 is activated. The output end of the third electric push rod 32 drives the first baffle 29 and the second baffle 31 to move, so that one end of the first discharge pipe 28 is closed and one end of the second discharge pipe 30 is opened, thereby discharging the diamond powder from the bottom of the drying box 11.
[0034] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
