[0022] 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. Example 1
[0023] Please see Figures 1-5 This utility model provides a technical solution:
[0024] An automated nitrogen production device includes a base 1 and a distillation unit 2. The distillation unit 2 is disposed on the top of the base 1. An input head 212 is provided in the distillation unit 2 for pressurizing liquid input to generate a deflecting jet. A temperature control rod 222 and a rotating drum 223 are provided in the distillation unit 2. The temperature control rod 222 is used to evaporate the liquid and condense the gas. The rotating drum 223 cooperates with the input head 212 so that the input head 212 generates a deflecting jet to drive the rotating drum 223 to rotate, thereby uniformly distributing the liquid and gas.
[0025] The distillation unit 2 includes a main body 21 mounted on top of the base 1, used for pressurizing liquid input to generate a deflecting jet, thereby driving the rotating drum 223 to rotate. The main body 21 includes a main tank 211 mounted on top of the base 1. An input head 212 is fixedly connected inside the main tank 211, and an outer ring 213 is fixedly connected outside the main tank 211. The outer ring 213 is hollow inside. A pressure relief valve 214 is fixedly connected to the top of the main tank 211, a first valve 215 is fixedly connected to the outside of the main tank 211, a second valve 216 is fixedly connected to the bottom of the main tank 211, and a third valve 217 is fixedly connected to the outside of the outer ring 213. Multiple input heads 212 are provided, and all input heads 212 are arranged around the central axis of the main tank 211. All input heads 212 are connected to the outer ring 213 and the main tank 211. All input heads 212 are deflected. The input ports of the input heads 212 are narrow and deflected, thus generating a deflecting jet.
[0026] The main body 21 is equipped with a distillation unit 22. The rotating drum 223 cooperates with the input head 212 to uniformly distribute liquid and gas. The distillation unit 22 includes a bottom plate 221 fixedly connected to the bottom of the main tank 211. A temperature control rod 222 is fixedly connected to the top of the bottom plate 221. The rotating drum 223 is wrapped around the temperature control rod 222. The bottom of the rotating drum 223 is rotatably connected to the top of the bottom plate 221. Multiple slots 224 are opened through the outside of the rotating drum 223. A fan plate 225 is fixedly connected to the outside of each slot 224. A connecting pipe 226 is fixedly connected to the bottom of the temperature control rod 222. The connecting pipe 226 passes through the bottom plate 221 and the main tank 211. The connecting pipe 226 is used to connect external heating and cooling equipment. The connecting pipe 226 and the temperature control rod 222 integrate resistance heating and coolant cooling. This is prior art and will not be described in detail.
[0027] In use, liquid nitrogen is first pressurized using existing pressurization equipment, then introduced into the outer ring 213 through the third valve 217, and then introduced through multiple input heads 212. At this time, due to the skewed setting of the input heads 212, the input high-pressure liquid nitrogen will generate a skewed jet. Since multiple air vanes 225 are set outside the rotating drum 223, the multiple skewed jets will drive the rotating drum 223 to rotate. The rotation of the rotating drum 223 and the air vanes 225 can evenly mix the liquid inside. At the same time, the temperature control rod 222 heats up, causing the liquid inside the main tank 211 to evaporate.
[0028] The high-pressure gas generated by evaporation is fed into the second distillation unit 2 at the top through a pipe made of existing technology. The temperature control rod 222 in the second distillation unit 2 cools and condenses the gas. At the same time, a deflected jet of high-pressure gas is generated during the input, which drives the rotating drum 223 to rotate, thereby uniformly mixing the gas. Example 2

The installation unit 3 includes a first connecting frame 31, a connecting plate 32, a second connecting frame 33, and fixing bolts 34, which are used to fix two or more sets of distillation units 2. The installation unit 3 includes a first connecting frame 31 set on the top of the base 1. Multiple connecting plates 32 are fixedly connected to the top of the first connecting frame 31. The multiple connecting plates 32 are arranged around the central axis of the first connecting frame 31. The top of the multiple connecting plates 32 is fixedly connected to the second connecting frame 33. Multiple fixing bolts 34 are threaded to the outside of both the first connecting frame 31 and the second connecting frame 33.
[0031] The first connecting frame 31 and the second connecting frame 33 are fixed to the base 1 and the distillation unit 2 by fixing bolts 34 respectively. Similarly, two or more sets of distillation units 2 can be installed and fixed to perform multiple evaporation and condensation separations to obtain high-purity nitrogen.
[0032] Furthermore, the distillation process within this apparatus can be automated by cooperating with existing cooling and heating equipment in distillation unit 2.
