[0002] Zinc oxide is the oxide of zinc. There are two methods for producing zinc oxide: direct method and indirect method. The indirect method produces zinc with high purity. The indirect method requires a large amount of heat source to heat production equipment such as reactors and evaporators. Zinc is evaporated in a high temperature environment to form gaseous zinc. The steam is oxidized by oxygen in the air to produce zinc oxide. Finally, the zinc oxide is cooled and formed through a cooling tube.
[0003] In the prior art, a reactor uses an indirect method to produce zinc oxide, in which a zinc ingot is placed in a reactor and the high temperature of the reactor evaporates the zinc to form gaseous zinc.
[0004] However, when this reactor uses the indirect method to produce zinc oxide, the zinc raw material uses zinc ingots, which are large in size and require a long time for melting and then evaporation and gasification, which affects the preparation efficiency of zinc oxide. Utility Model Content
[0005] The utility model aims to provide a reactor for producing and processing zinc oxide in view of the problem in the background technology that the large volume of zinc ingots leads to slow gasification speed and affects the preparation efficiency of zinc oxide.

[0030] Example 1
[0031] This embodiment provides a reactor for producing and processing zinc oxide, such as Figure 1 As shown, it includes a base 1, a reaction chamber 3 is fixedly installed on the top of the base 1, and an oxygen box 4 is fixedly installed on the top of the reaction chamber 3; the oxygen box 4 supplies oxygen to the reaction chamber 3. A feeding platform 2 is fixedly installed on the top of the base 1 and on the left side of the reaction chamber 3, and an inclined feeding chute is opened on the top of the feeding platform 2, and a zinc block is arranged on the feeding chute.
[0032] like Figure 2 As shown, a crushing assembly 5 is arranged inside the base 1, and the crushing assembly 5 includes a feed port 51 and a crushing device. An inclined feed port 51 is opened on the left side of the reaction bin 3. The zinc block enters the interior of the reaction bin 3 from the feed port along a parabolic trajectory, and the crushing device is located at the moving trajectory of the zinc block.
[0033] like Figure 2 and 3 As shown, the crushing device includes a main crushing roller 52 and an auxiliary crushing roller 55. The end of the main crushing roller 52 is fixedly connected to a motor through a rotating shaft. The main crushing roller 52 and the auxiliary crushing roller 55 are both provided with crushing teeth. The positions of the crushing teeth on the main crushing roller 52 and the auxiliary crushing roller 55 are staggered. The ends of the main crushing roller 52 and the auxiliary crushing roller 55 are both rotatably connected to the reaction chamber 3. Since the zinc block is large in size and is not easy to melt or evaporate, the zinc block is crushed by the main crushing roller 52 and the auxiliary crushing roller 55 so that the zinc block is broken into small particles, and the small particles melt quickly when heated.
[0034] like Figure 3 As shown, a first gear 53 is fixedly mounted on the end of the main crushing roller 52, and a second gear 54 is fixedly mounted on the end of the auxiliary crushing roller 55, and the first gear 53 is meshedly connected with the second gear 54. The main crushing roller 52 drives the first gear 53 to rotate, and the first gear 53 drives the second gear 54 and the auxiliary crushing roller 55 to rotate, so that the main crushing roller 52 and the auxiliary crushing roller 55 rotate in opposite directions, thereby increasing the crushing effect.
[0035] In this embodiment, the zinc block is crushed into small particles by the main crushing roller 52 and the first gear 53 to increase the heating area of the zinc block and avoid the zinc block being too large, which causes the zinc block to melt and evaporate slowly, thereby reducing the oxidation efficiency of zinc oxide.
[0036] Example 2
[0037] Based on Example 1, this example proposes a reactor for producing and processing zinc oxide, such as Figure 4As shown, an oxygen supply assembly 6 is arranged inside the base 1, and the oxygen supply assembly 6 includes a heating plate 61, a lower oxygen pipe 62 and an upper oxygen pipe 63. The lower oxygen pipe 62 and the upper oxygen pipe 63 are both connected to the oxygen box 4, and the oxygen spray ports of the lower oxygen pipe 62 and the upper oxygen pipe 63 face the zinc block. Two lower oxygen pipes 62 and two upper oxygen pipes 63 are provided, and the ends of the lower oxygen pipes 62 and the upper oxygen pipes 63 are fixedly connected to the reaction chamber 3. The lower oxygen pipe 62 is located below the moving track of the zinc block, and the upper oxygen pipe 63 is located above the moving track of the zinc block. Spraying is performed from both sides of the zinc block through the lower oxygen pipe 62 and the upper oxygen pipe 63, so as to expand the contact area between the zinc block and oxygen and accelerate the oxidation efficiency.
[0038] The inner wall of the reaction chamber 3 is fixedly connected to the heating plate 61, and the heating plate 61 is located directly below the crushing device. A baffle is fixedly installed on the side of the reaction chamber 3 facing the heating plate 61, and the baffle is attached to the front and back sides of the heating plate 61. The baffle intercepts the zinc block falling from the crushing device to prevent the zinc block from falling below the heating plate 61. After the crushed zinc block falls on the heating plate 61, if the zinc block is not completely melted, the high-pressure oxygen sprayed from the lower oxygen pipe 62 will move the zinc particles that are not completely melted, and the zinc particles roll along the heating plate 61 to gradually melt and evaporate.
[0039] A collecting tray 64 is fixedly installed on the inner wall of the reaction chamber 3 and just below the rear end of the heating plate 61. A cooling pipe 65 is fixedly installed at the end of the collecting tray 64. A suction fan is rotatably connected inside the cooling pipe 65. The zinc oxide gas is sucked into the cooling pipe 65 by the suction fan to cool and solidify to form zinc oxide particles.
[0040] In this embodiment, the zinc blocks are broken by the breaking device and then thrown out to perform parabolic motion. The inertia of zinc blocks with different gravities is different, and the resulting parabolic motion trajectories are different, so that the zinc blocks gathered together are thrown into the air and separated, avoiding a large number of zinc blocks gathering together and heat not circulating, resulting in the zinc blocks located outside melting while the zinc blocks located inside not melting, affecting the melting efficiency. The lower oxygen pipe 62 and the upper oxygen pipe 63 are placed on both sides of the moving trajectory of the zinc blocks to increase the contact area between the zinc blocks and oxygen and accelerate the oxidation efficiency.
[0041] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
