Abstract
Description
Technical Field
[0001] This utility model relates to powder processing equipment, and in particular to a high-efficiency micro-powder processing equipment. Background Technology
[0002] Ultrafine powder technology, as an emerging process, produces powders with excellent surface properties, such as dispersibility and solubility, after materials are ultra-finely pulverized. Due to the significant characteristics of the newly generated particles, including surface effects, quantum size effects, small size effects, and quantum tunneling effects, ultrafine powders have been widely used in electrical engineering, pharmaceuticals, and chemical industries. However, existing ultrafine powder processing equipment often encounters difficulties in operation due to the presence of large pieces of material in the raw materials, hindering the grinding process and impacting the overall workflow. This can also easily damage the equipment. Furthermore, existing ultrafine powder screening machines often require disassembly for cleaning and handling of substandard materials after prolonged use. Once the screening screen is removed, the equipment cannot function properly with the production equipment, leading to unstable and unsustainable operation. Utility Model Content
[0003] The purpose of this invention is to provide a high-efficiency micro-powder processing device to solve the problems existing in the prior art.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A high-efficiency micro-powder processing device includes a workbench, a feeding device on the top of the workbench, the feeding device including a circular vibrating screen, a material cylinder and a feed pipe, one end of the feed pipe communicating with the top of the inner interior of the material cylinder, the material cylinder being fixedly installed on the top of the circular vibrating screen, the circular vibrating screen being fixedly installed on the top of the workbench, the bottom of the material cylinder communicating with the top of the inner interior of the circular vibrating screen, the bottom end of the circular vibrating screen communicating with one end of a ventilation pipe, and the top end of the circular vibrating screen communicating with one end of a suction pipe.
[0005] By adopting the above technical solution, the feed pipe conveys the material into the cylinder during use. After entering the cylinder, the material falls from top to bottom into the circular vibrating screen. The circular vibrating screen screens the material. Qualified material falls into the worktable through the circular vibrating screen, while unqualified material is vibrated to the periphery of the screen by the circular vibrating screen and then sucked in by the suction pipe. The other end of the ventilation pipe is equipped with filter cotton. Because the suction pipe will create negative pressure inside the circular vibrating screen during suction, a ventilation pipe with a filtration function is required to replenish the air inside the circular vibrating screen and prevent the suction pipe from re-extracting the filtered material through the circular vibrating screen. It should be noted that in the technical solution of this application, the top center of the screen inside the circular vibrating screen needs to be raised upwards. The angle of this protrusion is between -2° and 0°. Only in this way will large particles of material move to the periphery more quickly during vibrating screening.
[0006] In a further embodiment, the bottom of the circular vibrating screen is connected to one end of the discharge pipe, the outside of the discharge pipe is covered with a cooling pipe, the outer wall of the cooling pipe is spirally wound with a water-cooling pipe, the outside of the cooling pipe is covered with a heat insulation layer, the heat insulation layer is used to cover the water-cooling pipe on the cooling pipe, and the water-cooling pipe is used to maintain the temperature inside the cooling pipe.
[0007] By adopting the above technical solution, the feed pipe is connected to the top of the inner cylinder when the device is in use. The feed pipe is used to transport materials into the cylinder. After falling, the materials are separated by the vibrating screen. In order to ensure that the mixed materials can quickly return to room temperature after being screened by the circular vibrating screen, they are passed through a cooling pipe. The cooling pipe only needs to be maintained at 18 degrees Celsius to 20 degrees Celsius. The reason why the temperature of the materials increases is because they absorb the heat of the vibrating screen when passing through the inside of the vibrating screen. Since the vibrating screen works by high-frequency vibration, it is inevitable that it will heat up during operation.
[0008] In a further embodiment, the middle section of the barrel has an internally and externally connected mounting hole, and a permanent magnet is fixedly installed in the mounting hole.
[0009] By adopting the above technical solution, a permanent magnet can be used to adsorb any magnetic materials that may exist in the material. These magnetic materials may be metal particles or other metallic substances mixed in during powder grinding.
[0010] In a further embodiment, the circular vibrating screen includes a shell, a screen plate, a vibrating motor, and a buffer base. The vibrating motor is fixedly installed at the bottom of the shell and is used to vibrate the shell. The screen plate is fixedly installed at the inner top of the shell. The shell is fixedly installed on the buffer base, which is used to reduce the noise when the shell vibrates.
[0011] By adopting the above technical solution, the drive module consists of a motor and a reduction gear, and its purpose is to provide greater torque to the stirring rod.
[0012] In a further embodiment, a discharge port is provided at the bottom of the housing, and a solenoid valve is fixedly installed inside the discharge port.
[0013] By adopting the above technical solution, the solenoid valve is used to control the opening and closing of the discharge port.
[0014] In summary, this utility model has the following beneficial effects: 1. Materials are screened by a circular vibrating screen. Qualified materials fall into the worktable through the circular vibrating screen, while unqualified materials are vibrated to the periphery of the screen by the circular vibrating screen and then sucked in by the suction pipe, thereby achieving the effect of real-time cleaning of the vibrating screen.

The feeding device 2 includes a circular vibrating screen 21, a material cylinder 22, and a feed pipe 23. One end of the feed pipe 23 is connected to the top of the inner interior of the material cylinder 22. The material cylinder 22 is fixedly installed on the top of the circular vibrating screen 21, which is also fixedly installed on the top of the workbench 1. The bottom of the material cylinder 22 is connected to the top of the inner interior of the circular vibrating screen 21. A ventilation pipe is connected to the bottom of the circular vibrating screen 21, and a suction pipe 3 is connected to the top of the circular vibrating screen 21. The bottom of the circular vibrating screen 21 is connected to an internal cooling pipe 4 of the workbench 1. The outer wall of the cooling pipe 4 is spirally wound with water-cooling pipes. The outer side of the cooling pipe 4 is covered with an insulation layer. The insulation layer is used to cover the water-cooling pipes on the cooling pipe 4. The water-cooling pipes are used to maintain the internal temperature of the cooling pipe 4. The middle section of the material cylinder 22 has an internal and external connecting mounting hole. A permanent magnet 5 is fixedly installed in the mounting hole. The workbench 1 includes a mounting frame, a shell, a drive module and a stirring rod.

[0020] Specific implementation process: During use, the feed pipe conveys materials into the cylinder. After entering the cylinder, the materials fall from top to bottom into the circular vibrating screen. The circular vibrating screen screens the materials. Qualified materials fall into the worktable through the circular vibrating screen, while unqualified materials are vibrated to the periphery of the screen by the circular vibrating screen and then sucked in by the suction pipe. The other end of the ventilation pipe is equipped with filter cotton. Because the suction pipe will create negative pressure inside the circular vibrating screen during suction, a ventilation pipe with a filtration function is required to replenish air inside the circular vibrating screen, preventing the suction pipe from re-extracting the filtered materials through the circular vibrating screen. It should be noted that in the technical solution of this application, in practical use, the top center of the screen inside the circular vibrating screen needs to be raised upwards. The inclination angle of this protrusion is between -2° and 0°. Only in this way will large particles of materials move to the periphery more quickly during vibrating screening, thereby achieving the effect of real-time cleaning of the vibrating screen.
