[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.
[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0021] The utility model embodiment provides an ultra-fine silver powder production device for silver electrolytic refining, such as Figure 1-4 As shown, the ultrafine silver powder production equipment for silver electrolytic refining includes: an installation box 1, in which a drying kettle 2 is arranged, and the drying kettle 2 is used to process the ultrafine silver powder electrolytically refined after washing; an electric heating tube 3 for heating, and the electric heating tube 3 is arranged on the drying kettle 2; a lifting kettle cover 4, the kettle cover 4 is arranged in the installation box 1, and a shaft 5 is rotatably installed on the kettle cover 4, and a stirring frame 6 for stirring the ultrafine silver powder electrolytically refined is arranged on the bottom end of the shaft 5; a first motor 7 for driving the shaft 5, the first motor 7 is fixedly installed on the top of the kettle cover 4, and the output shaft of the first motor 7 is fixedly connected to the top of the shaft 5; an adjustment mechanism for adjusting the drying kettle 2, and the adjustment mechanism is arranged in the installation box 1.
[0022] It should be noted that the application effect of using the traditional electric hot air drying oven in the drying process of electrolytically refined ultrafine silver powder is not ideal, and there are a series of significant deficiencies. Ultrafine silver powder is a special material with a small particle size and a relatively large specific surface area, which makes it exhibit unique physical and chemical properties during the drying process; first, due to the small particle size of ultrafine silver powder, the interaction force between particles becomes particularly significant. In the traditional electric hot air drying process, silver powder particles are easily agglomerated due to the effect of surface energy, resulting in the occurrence of silver powder agglomeration, which not only affects the dispersion and fluidity of silver powder, but also may have an adverse effect on subsequent applications; secondly, the large specific surface area of ultrafine silver powder means that its surface energy is high, which makes it easier for silver powder particles to absorb moisture and impurities in the air during the drying process. The traditional electric hot air drying method often cannot achieve uniform heating of silver powder particles, resulting in excessively high or low temperatures in some areas, thereby exacerbating the agglomeration and adsorption of silver powder; in addition, the drying efficiency of the electric hot air drying oven is relatively low and the drying time is long. The drying process of ultrafine silver powder requires more precise control, and traditional drying methods often cannot meet this demand. Long drying time not only increases production costs, but may also lead to a decline in the quality of silver powder, such as oxidation, discoloration and other problems. In summary, the traditional electric heating blast drying oven has problems such as silver powder compaction, uneven heating, and long drying time during the drying process of electrolytically refined ultrafine silver powder.
[0023] In this embodiment, the installation box 1 provides a closed working environment to ensure the stability and safety of the drying process. The drying kettle 2 is used as a core component for processing the washed electrolytically refined ultrafine silver powder to ensure that the silver powder can be evenly heated during the drying process to avoid agglomeration and hardening. The electric heating tube 3 is used as a heating element. Through reasonable layout and power control, efficient and uniform heating of the inside of the drying kettle 2 is achieved, which helps to avoid the hardening and adsorption of the ultrafine silver powder due to uneven heating during the drying process, thereby improving the drying effect. The design of the lifting kettle cover 4 makes it easy to open or close the drying kettle 2 when necessary, which is convenient for adding and removing the silver powder. The stirring frame 6 is driven by the first motor 7 to stir the silver powder during the drying process, which effectively prevents the agglomeration and hardening of the silver powder and improves the drying uniformity. The adjustment mechanism can adjust the inclination angle of the drying kettle 2 for subsequent pouring.
[0024] In a further preferred embodiment of the utility model, the adjustment mechanism includes: an assembly frame 8 symmetrically fixedly installed in the installation box 1; a rotating shaft 9 rotatably installed on the assembly frame 8, and the other end of the rotating shaft 9 is fixedly connected to the drying kettle 2; a second motor 10 fixed in the installation box 1 for driving the rotating shaft 9; a coupling 11 fixed on the output shaft of the second motor 10, and one end of the coupling 11 is fixedly connected to the corresponding rotating shaft 9.
[0025] In this embodiment, the symmetrical fixed installation of the assembly frame 8 ensures the stability and balance of the entire adjustment mechanism, and provides a solid foundation for subsequent adjustment operations. The rotating shaft 9 is installed on the assembly frame 8 by rotation, and the other end of the rotating shaft 9 is fixedly connected to the drying kettle 2, thereby realizing the linkage between the drying kettle 2 and the adjustment mechanism. The second motor 10 is used as a driving source and is connected to the rotating shaft 9 through a coupling 11, so as to accurately control the rotation of the rotating shaft 9. The design of the coupling 11 ensures the stable connection and efficient transmission between the motor output shaft and the rotating shaft 9, so that the drying kettle 2 can tilt and adjust its angle to dump the ultrafine silver powder after drying.
[0026] In a further preferred embodiment of the utility model, an electric hydraulic rod 12 for adjusting the kettle cover 4 is fixedly installed in the installation box 1, and a connecting block 13 is fixedly installed on the top of the output rod of the electric hydraulic rod 12, and the bottom end of the connecting block 13 is fixedly connected to the top of the kettle cover 4.
[0027] In this embodiment, the electric hydraulic rod 12 fixedly installed in the installation box 1 plays a key role. As a highly efficient transmission element, the electric hydraulic rod 12 realizes the lifting and lowering control of the kettle cover 4 through the telescopic movement of its output rod. This design makes the opening and closing operations of the kettle cover 4 simpler and faster, greatly improving the production efficiency.
[0028] In a further preferred embodiment of the utility model, an operation port is provided on one side of the installation box 1, a box door 14 is provided in the operation port, a vent, a hinge 15 and a handle lock 16 are provided on the box door 14, and the hinge 15 is fixedly connected to the box door 14.
[0029] In this embodiment, the entry of foreign impurities and dust is prevented, thereby ensuring the purity of the drying process; the air vents provided on the box door 14 allow air circulation, ensuring the ventilation inside the installation box 1, and preventing the accumulation of heat and excessive humidity caused by airtightness. This design not only ensures the drying effect, but also avoids possible safety hazards; the fixed connection between the hinge 15 and the box door 14 enables the box door 14 to be opened and closed stably, while ensuring its good durability. The addition of the handle lock 16 further enhances the safety of the box door 14, prevents unauthorized personnel from opening the operating port at will, and protects the safety and stability inside the equipment.
[0030] In a further preferred embodiment of the utility model, a material guide trough for pouring ultrafine silver powder is provided on the top edge of the drying kettle 2, and a temperature controller adapted to the electric heating tube 3 is provided on the drying kettle 2.
[0031] In this embodiment, the opening of the material guide trough makes the process of pouring the ultrafine silver powder smoother and more efficient, and the setting of the thermostat makes the heating process of the electric heating tube 3 more accurate and controllable. The thermostat can automatically adjust the heating power of the electric heating tube 3 according to the preset temperature range to ensure that the temperature in the drying kettle 2 is always maintained within a suitable range. This not only avoids problems such as melting or oxidation of the silver powder caused by excessive temperature, but also improves the consistency and stability of the drying effect. At the same time, the thermostat also has an overheating protection function. Once the temperature exceeds the safe range, the power supply will be automatically cut off to prevent possible safety accidents.
[0032] In a further preferred embodiment of the present invention, support columns are symmetrically fixedly installed on the bottom of the installation box 1, and foot pads are fixedly installed on the bottom ends of the support columns.
[0033] In this embodiment, the symmetrical installation of the support columns ensures the stable support of the installation box 1, and effectively prevents the equipment from shaking or tilting due to unstable center of gravity during operation. This stability is crucial for the drying process of ultrafine silver powder, and can avoid problems such as silver powder scattering or uneven drying caused by equipment shaking; at the same time, the foot pad design at the bottom of the support column also plays a key role. The foot pad is usually made of wear-resistant and non-slip material, which can increase the friction between the equipment and the ground, further improving the stability of the equipment. In addition, the foot pad can also isolate the direct contact between the equipment and the ground, reducing the impact of uneven ground or vibration on the equipment.
[0034] In a further preferred embodiment of the utility model, a shielding shell for covering the first motor 7 is arranged on the kettle cover 4, and a plurality of heat dissipation openings are opened on the shielding shell.
[0035] In this embodiment, the shielding shell can play a shielding and protective role to prevent people from accidentally touching and getting injured when the first motor 7 is running.
[0036] In summary, the ultrafine silver powder production equipment for silver electrolytic refining provided by the technical solution realizes efficient and uniform drying of ultrafine silver powder by adopting components such as a drying kettle 2, an electric heating tube 3, a lifting kettle cover 4, a stirring rack 6 and an adjustment mechanism, and solves the problems of silver powder compaction, uneven heating, and long drying time in the traditional electric heating blast drying oven during the ultrafine silver powder drying process. This not only improves the production efficiency and output of ultrafine silver powder, but also ensures the quality of silver powder, and meets the market demand for high-quality ultrafine silver powder.
[0037] Compared with the related art, the uniform heating of the electric heating tube 3 and the stirring action of the stirring frame 6 effectively avoid the agglomeration and compaction of the ultrafine silver powder during the drying process, thereby improving the drying uniformity and efficiency; the application of the electric hydraulic rod 12 makes the lifting and lowering operation of the kettle cover 4 simpler and faster, and the setting of the operating port and the equipment of the box door 14 also facilitate the observation and internal maintenance of the equipment; the design of the support column and the foot pad enhances the stability of the equipment.
