Description

Technical Field

[0001] This utility model relates to the field of plasma reactor technology, specifically a plasma reactor for preparing zinc oxide with a stirring structure. Background Technology

[0002] Plasma reactors utilize the high temperature and high activity of plasma to promote the rapid synthesis of zinc oxide and effectively reduce the introduction of impurities. For example, in the preparation of nanoscale zinc oxide, the metal is heated to a liquid state, and the anode is inserted into the hot molten metal. Under the action of a DC power supply, the plasma arc between the anode and cathode causes the hot molten metal to rapidly vaporize. After vaporization, the metal instantly combines with oxygen in the air to form zinc oxide. In plasma-enhanced thermal oxidation, for instance, metallic zinc forms zinc vapor at an appropriate temperature. In a mixture of oxygen and argon, the oxygen ionizes into ions during plasma discharge, reacting with zinc to form zinc oxide nuclei, which then extend into oxygen-rich regions to form zinc oxide nanorods.

[0003] For example, Chinese patent CN216049209U discloses an energy-saving and environmentally friendly plasma reactor. In this utility model, cold water is added to the first heat-conducting copper pipe, the second heat-conducting copper pipe, the cold water pipe, the hot water pipe, and the connecting pipe, and a water pump is used to circulate it. This allows the excess heat generated in the reaction core to be carried out without melting the core wall. The excess heat is used to heat the water in the water collection tank for use by nearby residents, achieving the purpose of energy saving, emission reduction, and improved resource utilization. This invention is worthy of vigorous promotion.

[0004] However, existing energy-saving and environmentally friendly plasma reactors are not convenient for stirring the air inside the furnace during use. The zinc vapor, oxygen and zinc oxide generated by the reaction cannot be fully mixed, which leads to a decrease in reaction rate and poor reaction uniformity. At the same time, the materials are also prone to sticking to the furnace wall. Therefore, there is still room for further improvement.

[0005] Therefore, we propose a plasma reactor for zinc oxide preparation with a stirring structure to solve the problems mentioned above. Utility Model Content

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-5 This utility model provides a technical solution: a plasma reactor for preparing zinc oxide with a stirring structure, comprising: a reactor body 1, a reaction core 2, a feeding port 3, a chute 4, a cover plate 5, a discharge port 6, a box door 7, an inspection door 8, a heat insulation frame 9, a drive motor 10, a locking block 11, a slot 12, a pole rotating shaft 13, a connecting column 14, a mounting groove 15, a stirring blade 16, a sealing plate 17, fastening screws 18, and a cooling fan 19.

[0032] Existing energy-saving and environmentally friendly plasma reactors are not convenient for stirring the air inside the furnace during use. The zinc vapor, oxygen, and zinc oxide generated in the reaction cannot be fully mixed, which leads to a decrease in reaction rate and poor reaction uniformity. At the same time, the materials are also prone to adhering to the furnace wall. Therefore, there is still room for further improvement.

[0033] When using a plasma reactor for zinc oxide preparation with a stirring structure, such as Figure 1 , Figure 2 and Figure 3 As shown, the first step in zinc oxide preparation is to add raw materials. The cover plate 5 is slid along the groove 4 on the upper side of the reactor body 1, moving it away from the feeding port 3. The zinc metal and other raw materials required for zinc oxide preparation are then poured into the reaction core 2 inside the reactor body 1 through the feeding port 3. The cover plate 5 is then slid in the opposite direction to cover the feeding port 3 again and ensure a tight seal, preventing zinc vapor or materials from splashing out of the feeding port 3 during the reaction and ensuring the sealing of the reaction environment.

[0034] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the equipment is started to carry out reaction and stirring operations. The reaction core 2 starts working, and the high temperature and high activity of the plasma cause the raw materials to react and generate zinc vapor. At the same time, the drive motor 10 inside the heat insulation frame 9 and the cooling fan 19 on the upper side of the reactor body 1 are started. After the drive motor 10 is powered on, its output shaft drives the fixedly connected locking block 11 to rotate. Since the locking block 11 is engaged with the slot 12 opened on the upper side of the rotating shaft 13, the rotation of the locking block 11 will drive the rotating shaft 13 to rotate synchronously. The rotating shaft 13 is connected to the reactor body 1 through a ceramic bearing, which reduces rotational friction, ensures rotational stability, and also plays a role in heat insulation. The connecting column 14 on the outer side of the rotating shaft 13 rotates with the shaft, and the stirring blade 16 slidably connected in the mounting groove 15 of the connecting column 14 also rotates accordingly, which fully stirs the zinc vapor, oxygen and initially generated zinc oxide inside the reactor body 1, expands the contact area between materials, accelerates the reaction process and improves the reaction uniformity; the cooling fan 19 continuously dissipates heat for the rotating shaft 13 to prevent the drive motor 10 from overheating and avoids damage to equipment components caused by the high temperature generated by the reaction. At the same time, the heat insulation frame 9 provides heat insulation protection for the drive motor 10 to prevent the drive motor 10 from being affected by high temperature and thus its operating performance.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, after the zinc oxide preparation is completed, the unloading operation is performed. Rotate the lower front door 7 of the reactor body 1 to separate the door 7 from the discharge port 6. The zinc oxide generated by the reaction is discharged through the discharge port 6. After unloading is completed, rotate the door 7 in the opposite direction to make it fit tightly against the discharge port 6 again, preparing for the next reaction.

[0036] When it is necessary to clean the stirring components or residual materials on the furnace wall, first turn off the power to the equipment, open the inspection door 8 on the front side of the reactor body 1, reach into the furnace and find the connecting column 14 on the outside of the rotating shaft 13. Use a tool to unscrew the fastening screw 18 on the upper side of the connecting column 14 that is connected to the sealing plate 17. The fastening screw 18, the connecting column 14 and the sealing plate 17 are all threaded, which is easy to disassemble. Then move the sealing plate 17 up and slide the stirring blade 16 out of the mounting groove 15 of the connecting column 14 to clean the stirring blade 16. At the same time, the furnace wall of the reactor body 1 can also be cleaned through the inspection door 8 to remove residual materials. After cleaning, slide the stirring blade 16 back into the mounting groove 15, cover the sealing plate 17 and tighten the fastening screw 18, close the inspection door 8, and the cleaning operation is complete.

[0037] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
