Description

Technical Field

[0001] This utility model relates to a distillation apparatus, specifically an ammonia evaporation distillation apparatus, belonging to the technical field of ammonia purification apparatus. Background Technology

[0002] Ammonia is an inorganic compound with the chemical formula NH3. It is a colorless gas with a strong, pungent odor that turns moist red litmus paper blue. It produces a small amount of hydroxide ions in water and is weakly alkaline. Ammonia is one of the most widely produced and used chemicals in the world, mainly used in the production of nitric acid, fertilizers, explosives, and refrigerants. More than 80% of the world's ammonia is used in fertilizer production. Industrially, ammonia is also used in the compound semiconductor, light-emitting diode, and liquid crystal display panel markets, as well as the solar cell industry. In addition, ammonia is also used as a refrigerant and is widely used in large-scale industries.

[0003] Commercially available ammonia mixtures are typically low in concentration and require purification before use. This is usually achieved using a distillation apparatus. Existing methods generally involve injecting the ammonia mixture into a container, heating the mixture to a certain temperature to convert the liquid ammonia into a gaseous state, and then collecting the gaseous ammonia, thus purifying the ammonia. However, the container usually contains some air before use, and the amount of ammonia to be extracted each time varies depending on the specific needs. Sometimes only a small amount of ammonia needs to be extracted, which results in air remaining in the container, affecting the purity of the ammonia. Therefore, we provide a distillation apparatus for ammonia evaporation to solve these problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a distillation apparatus for ammonia evaporation, the specific technical solution of which is as follows:

[0005] A distillation apparatus for ammonia evaporation includes a housing, a distillation mechanism disposed below the housing, a plurality of distillation mechanisms being connected vertically together, a sealing ring being slidably connected to the inner wall of the housing, an exhaust mechanism being disposed inside the sealing ring, a movable mechanism being disposed above the exhaust mechanism, a transparent plate being connected to the front of the housing, and a support mechanism being disposed on the outer surface of the housing.

[0006] Preferably, the outer side of the housing is connected to a feed inlet and an air outlet, and the height of the air outlet is lower than the height of the feed inlet.

[0007] Preferably, the exhaust mechanism includes a fixed plate, the outer surface of which is connected to a sealing ring, and the inner wall of the fixed plate has a first ventilation opening.

[0008] Preferably, the movable mechanism includes a connecting rod, the lower end of which is connected to a sealing block, the upper end of which is connected to a pull plate, the outer surface of which is rotatably connected to a fixed disk, and the inner wall of which is provided with a second ventilation opening.

[0009] Preferably, the distillation mechanism includes a liquid storage cylinder, with an upper connection port connected to the upper part of the liquid storage cylinder and a lower connection port connected to the lower part of the liquid storage cylinder, the outer surface of the lower connection port being threadedly connected to the upper connection port.

[0010] Preferably, a heating plate is installed on the lower surface of the liquid storage cylinder, and a support rod is connected to the lower surface of the liquid storage cylinder.

[0011] Preferably, the support mechanism includes a movable rod, a fixing ring is fixedly connected to the outer surface of the movable rod, the outer surface of the fixing ring is fixedly connected to the housing, and a base plate is connected to the bottom of the movable rod.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This ammonia evaporation distillation device, by setting up components such as a sealing ring and a movable mechanism, allows air above and below the sealing ring to be connected by rotating the movable mechanism. When the sealing ring moves downward, the air between the sealing ring and the ammonia solution is squeezed out. Then, the movable mechanism seals the inside of the sealing ring, squeezing out the air above the ammonia solution mixture while isolating it from the outside. The ammonia solution mixture is then distilled by the distillation mechanism, achieving the effect of preventing ammonia from mixing with the air inside the shell. This solves the problem that existing containers generally contain a certain amount of air before use, which affects the purity of ammonia.

[0014] 2. This ammonia evaporation distillation apparatus is equipped with multiple distillation mechanisms and other components. During the distillation process, the ammonia-water mixture is stored in multiple storage cylinders. Each storage cylinder is heated separately by a heating plate, achieving a uniform heating effect to increase distillation efficiency. The number of distillation mechanisms can be adjusted according to the amount to be distilled each time, so that the upper surface of the ammonia-water mixture is always located at the lower part of the shell for easy observation and adjustment of the sealing ring position, while also reducing the amount of air in the apparatus.

[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] Please see Figures 1-5 The device includes a housing 1, with multiple distillation mechanisms 2 located below the housing 1 and connected vertically. A sealing ring 3 is slidably connected to the inner wall of the housing 1, and an exhaust mechanism 4 is located inside the sealing ring 3. A movable mechanism 5 is located above the exhaust mechanism 4. A transparent plate 6 is connected to the front of the housing 1, and a support mechanism 7 is located on the outer surface of the housing 1. The multiple distillation mechanisms 2 are interconnected and can store an ammonia-water mixture inside. The multiple distillation mechanisms 2 can be disassembled and connected, and the connection can be adjusted according to the amount of liquid being distilled. The sealing ring 3 is made of rubber, which can increase the sealing effect between the exhaust mechanism 4 and the housing 1. The transparent plate 6 on the housing 1 allows for observation of the liquid level inside during use. There are three support mechanisms 7 to support the housing 1.

[0023] The outer side of the shell 1 has an inlet 8 and an outlet 9. The height of the outlet 9 is lower than that of the inlet 8. The inlet 8 is used to feed the ammonia mixture into the interior of the shell 1. The outlet 9 is used to discharge the ammonia. After the ammonia evaporates, it is discharged to the outside through the outlet 9.

[0024] The exhaust mechanism 4 includes a fixed plate 401. The outer surface of the fixed plate 401 is connected to the sealing ring 3. The inner wall of the fixed plate 401 is provided with a first ventilation port 402. The sealing ring 3 can be driven to move up and down through the fixed plate 401.

[0025] The movable mechanism 5 includes a connecting rod 501, with a sealing block 502 connected to the lower end of the connecting rod 501 and a pull plate 504 connected to the upper end of the connecting rod 501. The outer surface of the sealing block 502 is rotatably connected to the fixed plate 401. A second ventilation port 503 is provided on the inner wall of the sealing block 502. The pull plate 504 can drive the connecting rod 501 and the sealing block 502 to move up and down and rotate. When the sealing block 502 moves up or down, it can drive the fixed plate 401 to move up or down, thereby driving the sealing ring 3 to move up or down, so as to adjust the position of the sealing ring 3. When the sealing block 502 rotates, the first ventilation port 402 and the second ventilation port 503 can overlap each other, so as to allow the air below and above the sealing ring 3 to communicate with each other. When the first ventilation port 402 and the second ventilation port 503 are staggered, the space below the sealing ring 3 can be sealed. The resistance generated by the rotation of the sealing block 502 is less than the resistance of the rotation of the sealing ring 3.

[0026] The distillation mechanism 2 includes a liquid storage cylinder 201. The upper part of the liquid storage cylinder 201 is connected to an upper connection port 202, and the lower part of the liquid storage cylinder 201 is connected to a lower connection port 203. The outer surface of the lower connection port 203 is threadedly connected to the upper connection port 202. The upper connection port 202 and the lower connection port 203 can be rotated and disassembled. When connected together, liquid can flow between them, flowing from one liquid storage cylinder 201 to another liquid storage cylinder 201. The uppermost upper connection port 202 is threadedly connected to the lower part of the housing 1, and the lowermost lower connection port 203 is threadedly connected to a screw cap 10 for sealing.

[0027] A heating plate 204 is installed on the lower surface of the liquid storage cylinder 201, and a support rod 205 is connected to the lower surface of the liquid storage cylinder 201. The heating plate 204 is used to heat the upper liquid storage cylinder 201. The heating plate 204 has a heating wire inside and uses resistance heating. There are multiple support rods 205, and their bottoms are in contact with the lower liquid storage cylinder 201 to increase the stability between multiple liquid storage cylinders 201 and prevent the liquid storage cylinder 201 from tilting.

[0028] The support mechanism 7 includes a movable rod 701, with a fixed ring 702 fixedly connected to the outer surface of the movable rod 701. The outer surface of the fixed ring 702 is fixedly connected to the housing 1. A base plate 703 is connected to the bottom of the movable rod 701. The movable rod 701 is made up of multiple hollow rods sleeved together, with threaded connections between the multiple rods. When rotating, the movable rod 701 can be extended or shortened to adapt to the overall height. The total height is different when the number of distillation mechanisms 2 is different.

[0029] The heating plate 204 in this application is a common electrical device in the prior art. This application will not elaborate on its model or internal structure. It can also be replaced by other heating components.

[0030] In use, this invention works as follows: First, adjust the number of distillation mechanisms 2 according to the required amount to be extracted, and simultaneously adjust the height of the support mechanism 7 accordingly. Pull the movable mechanism 5 upward, causing it to move the sealing ring 3 upward. After the sealing ring 3 moves above the feed inlet 8, an ammonia mixture is injected into the interior of the housing 1. Under the action of gravity, the ammonia mixture moves downward into the interior of each storage cylinder 201. Once the upper surface of the ammonia mixture has overflowed the inner bottom wall of the housing 1, stop injecting the ammonia mixture. Rotate the movable mechanism 5 so that the first vent 402 and the second vent 503 overlap, and the downward-moving sealing ring 501... The sealing ring 3 forces the air between the sealing ring 3 and the ammonia water through the second vent 503. When the sealing ring 3 approaches the upper surface of the ammonia water mixture, the first vent 402 and the second vent 503 are overlapped and offset, thereby squeezing out the air above the ammonia water mixture and isolating it from the outside. Then, the ammonia water mixture is distilled by the distillation mechanism 2. The emitted ammonia gas moves upward and pulls the movable mechanism 5 upward, causing the sealing ring 3 to move below the feed port 8 and above the outlet 9, so that the ammonia gas is discharged from the outlet 9 and collected, thus achieving the effect of preventing ammonia gas from mixing with the air inside the shell 1.

[0031] During the distillation process, the ammonia-water mixture is stored in multiple storage cylinders 201. Each storage cylinder 201 is heated by a heating plate 204 to achieve uniform heating and increase distillation efficiency. The number of distillation mechanisms 2 can be adjusted according to the amount to be distilled each time, so that the upper surface of the ammonia-water mixture is located at the lower part of the shell 1 each time it is used, so as to facilitate observation and adjustment of the position of the sealing ring 3, and also reduce the amount of air in the device.

These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way.
