[0018] The present invention provides a device for preparing inert zinc powder by atomization for continuous production. It has the following beneficial effects:

[0019] (I) In the inert zinc powder atomization preparation device, the zinc liquid will be initially refined when passing through the guide hole under the action of pressure, and finally enter the polymerization tank in the polymerization seat, and will be differentiated again through the diffuser hole connected to the polymerization tank. By setting a multi-level differentiation mechanism, the zinc liquid can be more evenly distributed in the atomization chamber after being differentiated into thin streams by multiple stages, so that the area of ​​contact between the atomizing gas and the zinc liquid is larger and more uniform, which helps to avoid the situation of too much or too little zinc liquid in some parts, and ensures that each part of the zinc liquid can be fully and stably atomized, thereby producing zinc powder with more uniform particle size, improving product quality, and the surface area of ​​the zinc liquid in the thin stream state is greatly increased compared with the large block of zinc liquid flow. When interacting with the atomizing gas, the heat and momentum exchange is more efficient, which can make the zinc liquid be atomized into tiny particles faster, thereby improving the whole device The production efficiency can be improved. In large-scale industrial production, the production time per unit output can be effectively shortened and the production cost can be reduced. The multi-level differentiation flow promotes the efficient atomization process, so that under the premise of achieving the same atomization effect, the required atomization gas pressure and flow rate can be appropriately reduced, which directly reduces the energy consumed to produce atomization gas and the operating load of supporting power equipment. In the long run, it saves a lot of electricity costs for enterprises, conforms to the production concept of energy conservation and emission reduction, and cooperates with the up and down movement of the top cover to realize automatic filling operation. Compared with the current operation of allowing zinc liquid to enter the atomization furnace through gravity, it not only improves the flow stability of zinc liquid and ensures the output of zinc powder, but also can provide a certain pressure effect in the process of zinc liquid entering the atomization furnace to avoid production failures caused by zinc liquid blockage.

[0020] (ii) In the inert zinc powder atomization preparation device, the zinc liquid will flow to the diffuser cover after passing through the diffuser hole. The size of the diffuser hole can be adjusted by rotating the adjusting cover matched therewith, so that the amount of zinc liquid entering the atomization furnace can be adjusted, thereby realizing the production of zinc powder particles of different sizes, greatly improving the applicability of the device. When the motor is working, it will also drive the atomization ring to rotate through the connecting rod, so that the atomization nozzle is in a rotating state when working, thereby greatly improving the coverage angle when the high-temperature nitrogen is sprayed out, avoiding the problem of atomization dead corners causing part of the zinc liquid to be unable to be effectively atomized and resulting in zinc liquid waste, and by arranging the toggle frame and the toggle plate, the zinc liquid can be kept in a state of stirring during the working process, thereby greatly improving the fluidity and thermal uniformity of the zinc liquid, and avoiding the problem of zinc liquid staying in the dead corner of the device for a long time and causing blockage.

[0021] (III) The inert zinc powder atomization preparation device, along with the reciprocating rotation of the working rod, also drives the auxiliary rod to reciprocate, and the reciprocating rotation of the auxiliary rod drives the cleaning ring to continuously move up and down along the inner surface of the atomizing furnace, thereby realizing the cleaning of the inner surface of the atomizing furnace, avoiding the problem of zinc powder waste caused by the adhesion of the atomized zinc powder to the inner surface of the atomizing furnace, and the zinc powder in the atomizing furnace can be stirred by the auxiliary frame that moves up and down and the rotating connecting rod, which can not only promote the cooling of the zinc powder, but also avoid the phenomenon of zinc powder agglomeration in the atomizing furnace, thereby greatly improving the working stability and practicality of the device.

[0022] (IV) The products produced by the inert zinc powder atomization preparation device are not flammable solids, explosives, self-heating substances, or substances that release flammable gases when in contact with water, which provides great convenience for storage, transportation, and downstream use. Different grading systems are selected to produce specific particle size products that meet production requirements at one time, avoiding material loss, power consumption, manpower consumption, testing consumption, equipment consumption, and site consumption caused by secondary grading. Since secondary grading is not required, the risk of dust explosion that may occur during the secondary grading process is also avoided. There is no need to unpack and repackage after production, which also ensures the initial performance of the product, saves material and manpower consumption for secondary packaging, and does not generate dust emissions. Nitrogen with a certain oxygen content is used as the atomizing gas, so that a dense zinc oxide protective layer is formed during the atomization powder spraying process to avoid the phenomenon of zinc powder agglomeration, thereby producing non-hazardous inert zinc powder that is different from the traditional industry.

[0046] During operation, when zinc powder needs to be prepared, the zinc ingot can be melted by the smelting furnace. The steps are as follows: 400 kg of zinc ingot is placed in the smelting furnace, the initial current is set to 75A, and the current is increased to 150A every half an hour, and then to 300A after another half an hour, and then to 400A after another half an hour. The furnace is heated to 650°C, and the zinc ingots are completely melted after two hours of heating. The holding furnace 62 is used to hold the zinc water and is connected to the atomizing furnace 1 to transport the zinc water to the atomizing furnace 1. When smelting starts, the holding furnace 62 is also prepared for heating. The initial current is set to 30A, and the current is increased to 60A every half an hour. After another half an hour, the current is adjusted to 90A, and after another half an hour, the current is adjusted to 120A. The temperature reaches 550°C, and the zinc liquid is fed from the atomizing furnace 1 through the input hole 64 on the top cover 63. The smelting furnace is introduced into the insulation furnace 62, and the motor is started at this time. The motor starts and drives the working rod 65 to reciprocate. With the reciprocating rotation of the working rod 65, the top cover 63 on the insulation furnace 62 is driven to move up and down. When the top cover 63 moves up, the insulation furnace 62 is in a negative pressure state, and then the zinc liquid is extracted into the insulation furnace 62 through the input hole 64. When the top cover 63 moves down, the zinc liquid enters the atomizing furnace 1 through the guide hole 68 on the guide column 66 under the action of pressure, and the high-temperature nitrogen is sprayed on the zinc liquid through the atomizing nozzle 614 on the atomizing ring 613 to produce zinc powder.

By setting a multi-level differentiation mechanism, the zinc liquid can be more evenly distributed in the atomization chamber after being differentiated into thin streams by multi-level differentiation, so that the area of ​​contact between the atomized gas and the zinc liquid is larger and more even, which helps to avoid the situation of too much or too little zinc liquid in some parts, and ensures that each part of the zinc liquid can be fully and stably atomized, so as to produce a particle size. More uniform zinc powder improves product quality. Compared with large zinc liquid flows, the surface area of ​​the zinc liquid in the thin stream state is greatly increased.

In large-scale industrial production, it can effectively shorten the production time per unit output and reduce production costs. In addition, the multi-level differentiation of the thin stream promotes the efficient atomization process, so that under the premise of achieving the same atomization effect, the required atomizing gas pressure, flow rate, etc. can be appropriately reduced, which directly reduces the energy consumed to produce the atomizing gas and the operating load of the supporting power equipment. In the long run, it saves a lot of electricity costs for the enterprise, which is in line with the production concept of energy conservation and emission reduction.In addition, the automatic injection operation is realized by cooperating with the up and down movement of the top cover 63. Compared with the current operation of allowing the zinc liquid to enter the atomizing furnace 1 by gravity, it not only improves the flow stability of the zinc liquid and ensures the output of zinc powder, but also can provide a certain pressure effect in the process of the zinc liquid entering the atomizing furnace 1, so as to avoid production failure caused by the blockage of the zinc liquid. After the zinc liquid passes through the diffuser hole 611, it will flow to the diffuser cover 79. By rotating the adjusting cover 711 matched therewith, the size of the differentiation hole 710 can be adjusted, so that the amount of zinc liquid entering the atomizing furnace 1 is adjustable, thereby realizing the production of zinc powder with particles of different sizes, greatly improving the applicability of the device. When the motor is working, it will also drive the atomizing ring 613 to rotate through the connecting rod 76, so that the atomizing nozzle 614 is in a rotating state when working, thereby greatly improving the coverage angle when the high-temperature nitrogen is sprayed, avoiding the generation of atomization dead angles that cause part of the zinc liquid to be The problem of zinc liquid waste caused by failure to obtain effective atomization is solved. By setting the toggle frame 72 and the toggle plate 612, the zinc liquid can be kept in a state of stirring during the working process, thereby greatly improving the fluidity and thermal uniformity of the zinc liquid and avoiding the problem of zinc liquid staying in the dead corner of the device for a long time and causing blockage. The reciprocating rotation of the working rod 65 will also drive the auxiliary rod 73 to reciprocate. The reciprocating rotation of the auxiliary rod 73 drives the cleaning ring 78 to move up and down along the inner surface of the atomizing furnace 1, thereby cleaning the inner surface of the atomizing furnace 1 and avoiding the problem of zinc powder waste caused by the atomized zinc powder adhering to the inner surface of the atomizing furnace 1. The zinc powder in the atomizing furnace 1 can also be stirred by the auxiliary frame 77 that moves up and down and the rotating connecting rod 76, which can not only promote the cooling of the zinc powder, but also avoid the phenomenon of zinc powder agglomeration in the atomizing furnace 1, thereby greatly improving the working stability and practicality of the device.
