DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0022] Embodiment one: please refer to Figure 1 -Figure 3 A cooling device for zinc oxide production includes a cooling tank 1 and a heating furnace 2 fixedly installed on the side of the cooling tank 1. The heating furnace 2 has a heating chamber 21 inside. A feeding port 22 is provided at the upper end of the heating furnace 2. A heating pad 3 is fixedly installed at the lower end of the heating furnace 2. An electric heating wire 31 is fixedly installed on the heating pad 3. An inlet assembly 5 is installed between the cooling tank 1 and the heating furnace 2.

[0023] In this embodiment: When using this device to prepare zinc oxide, zinc raw material can be added into the heating chamber 21 through the feeding port 22. After adding, the feeding port 22 is closed, and the zinc raw material in the heating chamber 21 is heated by the heating wire 31 on the heating pad 3 at the lower end. The zinc raw material in the heating chamber 21 is heated and evaporated by the heating wire. The high-temperature gas enters the interior of the cooling tank 1 through the inlet component 5. The interior of the cooling tank 1 is filled with cooling water. The zinc vapor is introduced into the water in the cooling tank 1 through the inlet component 5, cooled in the water, and precipitated. When this zinc oxide production cooling device is in use, the zinc vapor generated is introduced into the interior of the cooling tank 1 through the inlet component 5 and cooled and precipitated by the cooling water. It has a simple structure and high conversion efficiency.

[0024] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 2 - Figure 4 The inlet component 5 includes a gas supply pipe 51 fixedly installed on the side of the cooling tank 1. A one-way valve 52 is fixedly installed on the gas supply pipe 51. The two ends of the gas supply pipe 51 are respectively located inside the upper end of the heating furnace 2 and inside the lower end of the cooling tank 1. The one-way valve 52 allows the zinc vapor to move in one direction and directly introduce the generated zinc vapor from the heating furnace 2 into the cooling tank 1 through the gas supply pipe 51.

[0025] A connecting pipe 53 is fixedly installed at one end of the gas supply pipe 51. Several air outlets 54 are equidistantly opened on the side wall of the connecting pipe 53. The connecting pipe 53 is located at the lower end of the cooling tank 1, below the surface of the cooling water. The multiple air outlets 54 allow zinc vapor to flow outward through the multiple air outlets 54, increasing the contact area between the gas introduced into the cooling water and the water, which facilitates the precipitation of zinc oxide particles.

[0026] A baffle 13 is fixedly installed inside the cooling tank 1, and the inlet component 5 is also installed on the baffle 13. Inlet components are installed on the inner wall and sides of the cooling tank 1. The inlet component 5 installed inside can perform secondary cooling of zinc vapor to precipitate zinc oxide.

[0027] Water inlets 12 are provided on the upper ends of both sides of the cooling tank 1, and water outlets 11 are provided on both side walls of the cooling tank 1. Water can be added into the cooling tank 1 through the water inlets 12.

[0028] A vent valve 4 is fixedly installed on the upper wall of the cooling tank 1, which is away from the heating furnace 2. The cooling tank 1 is filled with cooling water, and the connecting pipe 53 is located below the water surface of the cooling water. The vent valve 4 can release the air separated by the secondary cooling to the outside to prevent the air pressure in the cooling tank 1 from being too high.

[0029] In this embodiment: When using this device to prepare zinc oxide, the zinc raw material in the heating chamber 21 is first heated and volatilized into zinc vapor by the heating wire 31. The zinc vapor enters the connecting pipe 53 through the gas supply pipe 51, and is then discharged outward through multiple gas outlets 54 on the side wall of the connecting pipe 53. When the gas is discharged through multiple gas outlets 54, the contact area between the gas and water can be increased as much as possible, so that the zinc oxide in the zinc vapor precipitates in the cooling water. After the first cooling, some zinc vapor in the precipitated gas still does not dissolve in the water. At this time, a second precipitation cooling is performed by the inlet component 5 on the internal baffle 13 to dissolve the unprecipitated zinc into the water. The excess gas is discharged outward through the pressure relief valve 4. When using this device, by setting the connecting pipe 53 at the end of the gas supply pipe 51, the multiple gas outlets 54 set on the connecting pipe 53 can increase the contact area between the gas and the cooling water, so that the zinc in the gas precipitates outward as much as possible. Through the second cooling, the zinc in the finally discharged gas dissolves into the water as much as possible.
