Abstract
Description
Technical Field
[0001] This utility model relates to the field of nitrogen purification technology, and in particular to a continuous nitrogen purification device. Background Technology
[0002] Nitrogen is a colorless and odorless gas under normal conditions. It is chemically inert and rarely reacts with other substances at room temperature, so it is often used to make preservatives. Nitrogen needs to be purified before use, and currently, purifying agents are commonly used to remove impurities mixed in with the nitrogen.
[0003] A continuous nitrogen purification device with publication number CN219091475U includes a purification tank and a water tank. The purification tank is equipped with a first filter screen for preliminary filtration of nitrogen. Several copper meshes are arranged on the right side of the first filter screen. The purification tank is equipped with a second filter screen, a first air permeable screen, a second air permeable screen and an activated carbon filter layer in sequence, which purifies nitrogen multiple times and effectively improves the purification effect.
[0004] However, when the copper wires in the copper mesh react with oxygen, copper oxide, which does not react with oxygen, is produced. This hinders the further reaction between the copper mesh and oxygen, reduces the absorption of oxygen from nitrogen, and affects the purification of nitrogen. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the formation of copper oxide on the surface of copper wires in a copper mesh that does not react with oxygen, which affects the purification of nitrogen. Therefore, a continuous nitrogen purification device is proposed.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] Design a continuous nitrogen purification device, including a purification tank, wherein a rotating heating component is rotatably installed inside the purification tank, and the rotating heating component is filled with copper particles, and the rotating heating component is used to heat, agitate and sieve the copper particles;
[0008] The purification tank is equipped with a collection component located below the rotary heating component, and the collection component is used to collect copper oxide powder that falls off the surface of copper particles;
[0009] The purification tank is equipped with an inlet pipe at the top and an outlet pipe at the bottom right end, and the outlet pipe is connected to the continuous purification assembly.
[0010] Furthermore, the rotating heating assembly includes a pair of turntables rotatably installed inside the purification tank, with a mesh cylinder and several connecting rods fixed between the pair of turntables. Several fine holes are opened through the outer wall of the mesh cylinder, and a circular hole is opened through the right end face of the left turntable. Several heating rods are installed in the circular hole, and the right ends of the heating rods are fixedly connected to the purification tank. A motor is fixedly installed on the left end face of the purification tank, and the output shaft of the motor passes through the purification tank and is fixedly connected to the turntable.
[0011] Furthermore, the collection assembly includes a slot formed on the lower outer wall of the purification tank, a collection plate is inserted into the slot, and the collection plate is positioned directly below the rotating heating assembly.
[0012] Furthermore, a filter plate is fixedly installed on the right end of the collection plate, and the filter plate is located on the left side of the gas outlet pipe of the purification tank.
[0013] Furthermore, the continuous purification assembly includes an air pump connected to the air outlet of the purification tank via a pipe. The air outlet of the air pump is connected to a water tank via a pipe, and the pipe extends through and to the bottom of the water tank. The air outlet at the top of the water tank is connected to a purification chamber via a pipe. The air outlet of the purification chamber is connected to a storage tank via a pipe, and the top of the storage tank is equipped with an exhaust pipe.
[0014] Furthermore, the purification chamber has four frames installed inside, and from bottom to top, the four frames are respectively equipped with a sponge layer, a filter screen, an air-permeable sieve, and an activated carbon filter layer.
[0015] The continuous nitrogen purification device proposed in this utility model has the following advantages: by setting up a mesh cylinder with copper particles, the nitrogen enters the mesh cylinder and reacts with the copper particles to remove oxygen. The copper particles have a larger surface area than the copper mesh, making the reaction more complete and faster. The rotating mesh cylinder can drive the copper particles to roll and rub, grinding away the copper oxide produced by the reaction between the copper particles and oxygen. This prevents the copper oxide from hindering the oxygen from continuing to react with the copper particles, ensuring the absorption of oxygen and the purification of nitrogen. At the same time, the rolling copper particles have more uniform and comprehensive contact with nitrogen. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figure 1-4 As one embodiment of this utility model, a continuous nitrogen purification device is disclosed, including a purification tank 1. A rotating heating component 2 is rotatably installed inside the purification tank 1, and the rotating heating component 2 is filled with copper particles. The rotating heating component 2 is used to heat, agitate, and sieve the copper particles.
[0023] The purification tank 1 is equipped with a collection component 3 located below the rotary heating component 2, and the collection component 3 is used to collect the copper oxide powder that falls off the surface of the copper particles.
[0024] The purification tank 1 is provided with an inlet pipe and an outlet pipe at the top and bottom right end, respectively, and the outlet pipe is connected to the continuous purification component 4.
[0025] The copper particles are heated and turned by the rotating heating component 2, so that the high-temperature copper particles react with the oxygen in the nitrogen gas injected through the air inlet pipe and flowing downward through the rotating heating component 2 and the copper particles, and copper oxide is generated on the surface. The turning copper particles rub against each other, wear away the copper oxide on their surfaces, and fall into the collection component 3 for collection after being screened by the rotating heating component 2.
[0026] It should be noted that the rotating heating assembly 2 includes a pair of turntables 21 rotatably installed inside the purification tank 1, and a mesh cylinder 22 and several connecting rods 23 are fixed between the pair of turntables 21. Several fine holes 24 are opened through the outer wall of the mesh cylinder 22. A circular hole is opened through the right end face of the left turntable 21, and several heating rods 25 are installed in the circular hole. The right ends of the heating rods 25 are fixedly connected to the purification tank 1. A motor 26 is fixedly installed on the left end face of the purification tank 1, and the output shaft of the motor 26 passes through the purification tank 1 and is fixedly connected to the turntable 21.
[0027] Heating rod 25 heats copper particles. Motor 26 drives two turntables 21 and mesh cylinder 22 to rotate, causing the copper particles to tumble and rub against each other in the mesh cylinder 22. Oxygen-containing nitrogen gas enters the purification tank 1, penetrates the mesh cylinder 22, and enters the gaps between the copper particles. Oxygen reacts with the copper particles to generate copper oxide on the surface. During the friction, the copper particles grind the copper oxide on the surface into powder and detach. Nitrogen gas then penetrates the mesh cylinder 22 again and leaves the mesh cylinder 22, carrying away some of the copper oxide powder.
[0028] Furthermore, the collection component 3 includes a slot 31 on the lower outer wall of the purification tank 1. A collection plate 32 is inserted into the slot 31, and the collection plate 32 is located directly below the rotating heating component 2. During the copper particle agitation process, copper oxide powder falls onto the collection plate 32 through the fine holes 24 on the mesh cylinder 22. After the operation stops, the collection plate 32 is removed for cleaning.
[0029] Furthermore, a filter plate 33 is fixedly installed on the right end of the collection plate 32, and the filter plate 33 is located on the left side of the gas outlet pipe of the purification tank 1. The nitrogen gas entering the gas outlet pipe of the purification tank 1 is filtered by the filter plate 33 to reduce the copper oxide powder carried in it, so that the filtered powder automatically falls onto the collection plate 32 under the action of gravity.
[0030] In some embodiments, the continuous purification component 4 includes an air pump 41 connected to the air outlet of the purification tank 1 via a pipe. The air outlet of the air pump 41 is connected to a water tank 42 via a pipe, and the pipe extends through and to the bottom of the water tank 42. The air outlet at the top of the water tank 42 is connected to a purification chamber 43 via a pipe. The air outlet of the purification chamber 43 is connected to a storage tank 44 via a pipe, and the top of the storage tank 44 is provided with an exhaust pipe 45.
[0031] Nitrogen gas is drawn into the bottom of water tank 42 by air pump 41 and then forms bubbles that rise. During the rising process, the bubbles come into contact with the water in water tank 42 and absorb and filter the impurities contained therein. The bubbles rise and burst, releasing nitrogen gas into purification tank 43 for continuous purification, and finally into storage tank 44 for storage.
[0032] Specifically, the purification box 43 has four frames 431 installed inside, and from bottom to top, the four frames 431 are respectively equipped with a sponge layer 432, a filter screen 433, an air-permeable screen 434 and an activated carbon filter layer 435.
[0033] Nitrogen gas enters the purification chamber 43 and passes through the sponge layer 432, filter screen 433, air permeable screen 434 and activated carbon filter layer 435 in sequence. After dehumidification, absorption and three-stage filtration and purification through the sponge layer 432, filter screen 433, air permeable screen 434 and activated carbon filter layer 435, it is discharged.
[0034] Working method: The copper particles are heated by heating rod 25, and the two turntables 21 and mesh cylinder 22 are rotated by motor 26, so that the copper particles roll and rub against each other in the mesh cylinder 22.
[0035] Under the suction of the air pump 41, the oxygen-containing nitrogen gas inlet pipe enters the purification tank 1 and penetrates the mesh cylinder 22 into the gap between the copper particles. The oxygen reacts with the tumbling copper particles and is absorbed, generating copper oxide on the surface of the copper particles. The copper particles grind the surface copper oxide into powder and detach it during friction. The nitrogen gas carries the copper oxide powder downward through the fine hole 24 on the mesh cylinder 22 and leaves the mesh cylinder 22.
[0036] Copper oxide powder passes through filter plate 33 and falls onto collection plate 32. After the operation stops, collection plate 32 is removed for cleaning.
[0037] After being filtered by filter plate 33, nitrogen enters the bottom of water tank 42 through air pump 41 and then forms bubbles that rise. During the rising process, the bubbles come into contact with the water in water tank 42 and absorb and filter the impurities contained therein. The bubbles rise and burst, releasing nitrogen into purification box 43.
[0038] After entering the purification chamber 43, the nitrogen gas undergoes dehumidification, absorption, and three consecutive filtrations through the sponge layer 432, filter screen 433, air permeable screen 434, and activated carbon filter layer 435 before entering the storage tank 44 for storage and being discharged through the exhaust pipe 45.
[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
