[0002] The production of ultrafine nickel oxide powder mostly adopts the solution atomization roasting method, which is to prepare the feed liquid by using nickel chloride hexahydrate as the nickel source, and then use an atomizing nozzle to spray the nickel chloride hexahydrate. The solution atomization roasting reaction is to atomize the nickel chloride solution into micron-sized droplets through the nozzle to form an aerosol, and then quickly dry it into ultrafine powder at high temperature, and carry out chemical reaction at the same time.

[0003] In the prior art, when producing ultrafine nickel oxide powder, the atomizing nozzle is connected to the reaction tube. The reaction tube is heated to increase the temperature inside the reaction tube so as to dry the droplets to form ultrafine powder. The atomizing nozzle is directly connected to the reaction tube, and the temperature on the reaction tube is also transmitted to the atomizing nozzle, which causes part of the water in the nickel chloride inside the atomizing nozzle to evaporate when passing through the outlet. When contacting with the carrier, it is easy to react directly. At this time, the particles of the nickel oxide powder produced are uneven and the particle diameter is large, which is easy to block the outlet. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the present invention, by setting the No. 1 restriction sleeve and the No. 2 restriction sleeve, the flow of airflow is used to reduce the heat of the main body. At the same time, by wrapping the No. 1 restriction sleeve and the No. 2 restriction sleeve, the airflow is concentrated at the position connecting the extended block and the fastening sleeve in the middle of the main body, so as to concentrate the heat dissipation and ensure the heat dissipation quality. By setting the semiconductor refrigeration sheet, the airflow is cooled by the semiconductor refrigeration sheet when entering, thereby increasing the heat dissipation effect.

[0017] 2. In the present invention, the gas conveying pipeline is divided into two parts by setting the assembly block, which can facilitate production and processing and reduce production costs. With the setting of the fastening sleeve, the assembly block and the extension block are connected by extrusion, which is convenient for installation on the one hand and can ensure the sealing between the two on the other hand. By setting the No. 1 limit rod and the limit groove, the position of the No. 1 side groove is limited during installation to ensure that the No. 1 side groove can be connected to the gas transmission channel after installation, thereby ensuring normal use.

[0018] 3. In the present invention, an inner air cavity is provided inside by setting a flow regulating rod, and a gas transmission channel is provided. When in use, the nickel chloride flowing out from between the inner cavity and the flow regulating rod is easily torn by the gas ejected from the inner air cavity to form atomized droplets, and then is impacted for the second time by the compression groove to be split again to form smaller droplets, thereby increasing the atomization effect, making the droplets smaller, and forming a nickelous oxide powder with a smaller diameter, so as to produce ultrafine nickelous oxide powder. In this way, the production effect is better, and the overall structure is simple, which is convenient for production and processing. The position of the liquid spray port is close to the compression groove, so the torn droplets can be ejected quickly, and the problem of secondary convergence of the droplets due to excessive distance and uneven size of the produced nickelous oxide powder can be prevented.

The number of the electric telescopic rods 31 is two. The two electric telescopic rods 31 are respectively fixedly connected to the middle of one side of the two top mounting plates 4. The flow regulating rod 33 is plugged into the sealing cap 14. The outer surface of the flow regulating rod 33 is provided with a connecting plate 32. A reinforcing rib is provided at the corner below the connecting plate 32. An inner sleeve groove 36 is provided through the middle of the connecting plate 32.

Through the setting of the flow regulating rod 33, the inner air cavity 35 is provided inside, and the gas transmission channel 19 is matched. When in use, the nickel chloride flowing out from between the inner cavity 110 and the flow regulating rod 33 is easily first The gas ejected from the inner air cavity 35 is torn to form atomized droplets, which are then impacted for the second time by the compression groove 120 and split again to form smaller droplets, thereby increasing the atomization effect, making the droplets smaller, and forming a smaller diameter of nickelous oxide powder to produce ultrafine nickelous oxide powder.

The liquid injection port 121 is close to the compression groove 120, so the torn droplets can be ejected quickly to prevent the problem of secondary convergence of droplets due to excessive distance and uneven size of the produced nickelous oxide powder.

[0039] The use method and working principle of the present device are as follows: during installation, the sealing cap 14 and the extension block 17 are respectively installed at the upper and lower ends of the connecting cavity 113, and then the No. 1 limit card rod 118 is connected to the limit groove 117 until the two compression grooves 120 are connected, and then the fastening sleeve 112 is sleeved on the outside of the assembly block 111 and connected with the thread on the outer surface of the extension block 17. When the installation is completed, one side of the mounting seat 114 is parallel to the side of the connecting body 11, and then the electric telescopic rod 31 is connected to the top mounting plate 4, and the connecting plate 32 is sleeved on the outer surface of the adjusting mechanism 3. When the threaded hole 37 is connected to the No. 2 side groove 38, the bolt 39 is installed in the threaded hole 37 until one end squeezes the No. 2 side groove 38, and the connecting plate 32 is fixed to the flow regulating rod 33, and then the flow regulating rod 33 is inserted into the sealing cap 14 until the through hole 310 is plugged into the output end of the electric telescopic rod 31, and then the nut 311 is connected to the electric telescopic rod 31. The output end is connected, the connecting plate 32 is fixedly installed with the output end of the electric telescopic rod 31, and then the connecting port 34 and the air inlet 12 are connected to the pipeline, and the other ends of the two pipelines are respectively installed with air pumps, and then the liquid inlet 13 is installed with the liquid delivery pipeline of the nickel chloride solution, and the mounting seat 114 is connected with the mounting position on the reaction tube, and then the lower ends of the No. 1 restriction sleeve 21 and the No. 2 restriction sleeve 22 are attached to the upper surface of the reaction tube, the side clamping plate 25 is connected to the top plate 4, and the bottom clamping groove 26 is clamped with the mounting seat 114, and then the semiconductor refrigeration piece 24 is connected with the restriction clamping groove 28, and the pipeline is connected to the two air extraction ports 23, and the other end of the pipeline is connected to the air pump, and then the semiconductor refrigeration piece 24 and the electric telescopic rod 31 are respectively energized, and the semiconductor refrigeration piece 24 is controlled to open, and the gap between the lower end of the flow regulating rod 33 and the inner cavity 110 is controlled by controlling the extension amount of the electric telescopic rod 31, so as to control the flow amount of the nickel chloride solution;

[0040] When in use, the position of the flow regulating rod 33 is adjusted by the electric telescopic rod 31, and the air pump is turned on first to make the gas flow out from the inner air cavity 35 and the compression groove 120, and the nickel chloride solution enters from the liquid inlet 13, enters the inner cavity 110, and flows out from the gap between the flow regulating rod 33 and the inner cavity 110. The gas sprayed from the inner air cavity 35 first tears the nickel chloride solution to form water mist, and then the water mist passes through the compression groove 120 and is torn again by the gas to form ultra-fine water mist, and then the water mist is sprayed from the liquid spray port 121 and enters the reaction tube for Reaction to produce nickelous oxide ultrafine powder. In this process, the exhaust port 23 draws out gas through the pipe and the air pump, so that the gas enters from the top of the No. 1 restriction sleeve 21 and the No. 2 restriction sleeve 22. The gas passes through the semiconductor refrigeration sheet 24 and is cooled by the semiconductor refrigeration sheet 24. The cooled gas then passes through the middle part of the connecting body 11, the extension block 17 and the fastening sleeve 112 to cool it. By lowering the temperature, the water inside the solution is not easy to evaporate, making it difficult to react and unable to produce nickelous oxide, thereby avoiding blockage.
