Description

Technical Field

[0001] The present invention relates to the technical field of nanomaterials, and in particular to low-temperature rapid sintering equipment and a process based on nanopowders. Background Art

[0002] With the widespread application of nanomaterials in new energy, electronics, aerospace, biomedicine and other fields, rapid prototyping and low-temperature sintering of nanopowders have gradually become hot topics in research and industrial development. Traditional nanopowder sintering processes often rely on high temperatures, high pressures, and long heat treatment processes. This not only consumes a lot of energy and has low efficiency, but also easily leads to nanoparticle agglomeration, growth, and grain coarsening, thus affecting the final density and performance of the material.

[0003] In the existing technology, in order to improve the sintering quality of nanopowders, some equipment has begun to introduce technical means such as low-temperature assisted sintering, cooling protection, and atmosphere control. However, most equipment has complex structures and separated processes, and often requires manual processing of nanopowders through multiple steps such as screening, loading, preheating, stirring, cooling, sintering, and exhaust gas treatment. Not only is the operation cumbersome, but the coordination between different processes is also not high, resulting in poor impurity control, serious powder loss, and low degree of automation during material processing.

[0004] Furthermore, during the nanopowder sintering process, smoke and dust are easily formed due to their extremely small particle size and wide distribution. Without effective exhaust and dust removal mechanisms, this not only affects the processing environment but can also endanger the health of operators. While some existing equipment features simple exhaust structures, they lack coordinated control over smoke and dust generation with multiple processes such as mixing, cooling, and feeding. This can lead to unstable sintering results, reduced material purity, and low overall energy efficiency. Summary of the Invention

[0005] The present invention aims to address the existing problem of dust formation during nanopowder sintering, which is easily caused by the extremely small and widely distributed particle size. Without effective exhaust and dust removal mechanisms, this not only affects the processing environment but can also endanger operator health. While some existing equipment features simple exhaust mechanisms, the lack of coordinated control between dust generation and multiple processes, such as mixing, cooling, and feeding, can lead to unstable sintering results, reduced material purity, and low overall energy efficiency.

[0034] Low-temperature rapid sintering process based on nanopowder: S1: Pour the nanopowder into the sieve plate 125. The elliptical block 121 rotates to vibrate the sieve plate 125, filtering out impurities and collecting them in the material receiving box 132. S2: Pull the pull rod 144 to drive the round block 142 to move to one side, and the round block 142 drives the clamping rod 145 to disengage from the clamping hole inside the rectangular block 140. After disengagement, the rectangular block 140 can be pulled to move to one side, driving the limiting long rod 139 to move to one side. The limiting long rod 139 disengages from the inside of the support frame 122. The support frame 122 can rotate with the rotating rod 128 as the center of the circle.

At the same time, the gear 134 drives the meshing rack 135 to move horizontally, driving the slide plate 1311 to move inside the long groove 129, and then drives the material receiving box 132 to move. At this time, the sieve plate 125 will not spill a small part of the nanopowder into the interior of the material receiving box 132 when pouring the internal nanopowder into the blanking plate 102.

[0036] S4: Motor 103 starts to drive the pulley to rotate, which drives pulley 1 107 to rotate through the belt, pulley 107 drives shaft 106 to rotate, shaft 106 drives pulley 2 108 to rotate, pulley 2 108 drives pulley 3 110 to rotate through belt 2 109, pulley 3 110 rotates through thin rod 111, thin rod 111 drives bevel gear 1 112 to rotate, bevel gear 1 112 drives meshing bevel gear 2 113 to rotate, bevel gear 2 113 drives stirring rod 1141 to rotate, and lid 114 drives cooler 115 on the outer surface to stir the nanopowder inside. S5: The inner wall of the heating tank 101 is cooled by the cooler 115, and the nano powder inside is subjected to low-temperature sintering processing. During the processing, the switch plate 116 is pushed to slide inside the slide groove 117 so that the feed port on the cover 114 is closed. Smoke will appear during the internal processing. When the bevel gear 112 rotates, it will drive the connecting rod 120 to rotate. At this time, the connecting rod 120 drives the fan 1181 to rotate. At this time, the air outlet 118 extracts the processing smoke inside the heating tank 101 through the air duct 119.

[0037] Working principle: When in use, the nano powder is poured into the inside of the sieve plate 125, and then the motor 103 is started by an external power supply. At this time, the motor 103 drives the elliptical block 121 to rotate through the round rod at the output end. At this time, the elliptical block 121 rotates on the outer surface of the sieve plate 125. At this time, the sieve plate 125 moves back and forth up and down under the elastic limit of the spring 123, so that it vibrates. After vibration, the impurities inside the nano powder can be screened out and screened to the inside of the material receiving box 132 for collection. After the screening is completed, by pulling the pull rod 144, the pull rod 144 drives the round block 142 to move to one side. At this time, the round block 142 drives the clamping rod 145 to detach from the clamping hole inside the rectangular block 140. After detachment, the rectangular block 1 40 moves to one side, and at the same time drives the limiting long rod 139 to move to one side. At this time, the limiting long rod 139 is separated from the inside of the support frame 122. At the same time, the support frame 122 can be rotated by the rotating rod 128 as the center of the circle. At this time, the nanometer powder screened inside the sieve plate 125 enters the surface of the blanking plate 102, and slides to the inside of the heating tank 101 through the blanking plate 102. Before that, the switch plate 116 is pulled to move inside the chute 117. After the movement, the feed port on the cover 114 is opened. After opening, the nanometer powder enters the interior of the heating tank 101 for processing. When the support frame 122 rotates, it will drive the rotating rod 128 to rotate. At this time, the rotating rod 128 drives the pulley four 131 to rotate. At this time, the pulley four 131 The material receiving box 132 drives the pulley five 133 to rotate, and the pulley five 133 drives the fixedly connected gear 134 to rotate. At the same time, the gear 134 drives the meshing rack 135 to move horizontally, thereby driving the slide plate 1311 to move inside the long groove 129. When the slide plate 1311 moves, it drives the material receiving box 132 to move. At this time, the sieve plate 125 will not spill a small part of the nano powder into the material receiving box 132 when pouring the internal nano powder into the blanking plate 102. When the sieve plate 125 is poured, the sieve plate 125 rotates in the opposite direction to drive the rotating rod 128 to rotate. At this time, the rotating rod 128 drives the meshing rack 131 through the pulley four 131, the material receiving box 132, the pulley five 133, and the gear 134. 5 moves in the opposite direction. At this time, the slide plate 1311 returns to the position just below the sieve plate 125. When the sieve plate 125 is tilted, the blocking bar 126 contacts the protrusion 127 to prevent the sieve plate 125 from rotating too much, resulting in incomplete tilting and the nano powder inside from being poured onto the surface of the blanking plate 102. When the motor 103 is started, it drives the pulley at its output end to rotate. At this time, the pulley 1 107 is rotated through the belt. At this time, the pulley 1 107 drives the rotating shaft 106 to rotate. At this time, the rotating shaft 106 drives the pulley 2 108 to rotate. At this time, the pulley 2 108 drives the pulley 3 110 to rotate through the belt 2 109. The pulley 3 110 rotates through the thin rod 111, and the thin rod 111 drives the bevel gear 1 112 to rotate.At this time, the bevel gear 112 drives the meshing bevel gear 2 113 to rotate, and the bevel gear 2 113 drives the stirring rod 1141 to rotate, and the cover 114 drives the cooler 115 on the outer surface to stir the nano powder inside it. The cooling of the cooler 115 cools the inner wall of the heating tank 101, thereby performing low-temperature sintering processing on the nano powder inside it. During processing, the switch plate 116 is pushed to slide inside the slide groove 117 so that the feed port on the cover 114 is closed. Smoke and dust will appear during internal processing. When the bevel gear 112 rotates, it will drive the connecting rod 120 to rotate. At this time, the connecting rod 120 drives the fan 1181 to rotate. At this time, the air outlet 118 extracts the processing dust inside the heating tank 101 through the air guide pipe 119. When in use, the motor 103 will drive the screening device and the fan 1181 to move, saving resources. The model of motor 103 is Y180M-4, the voltage is 380V, and the power is 3kW. -11kW. ,
