Description

Technical Field

[0001] This utility model relates to the field of nitrogen purification technology, specifically an electronic-grade nitrogen purification device. Background Technology

[0002] Nitrogen purification refers to the removal of impurities from nitrogen using physical or chemical methods. Industrially, nitrogen purification mainly removes oxygen from nitrogen to improve its purity.

[0003] According to a purification device disclosed (Publication No.: CN219615817U), the cells to be purified are placed in glass test tubes, which are then placed in corresponding test tube slots. A spring supports a positioning ring, which positions the glass test tubes on both sides, preventing hard contact between the glass test tubes and the test tube slots during rotation. Simultaneously, the positioning ring can clamp test tubes of different diameters under the action of the spring. With the spring compressed, centrifugation of test tubes of different diameters can be performed within the same purification unit without changing the purification unit, reducing labor intensity and improving product adaptability. Starting the motor causes the output shaft to drive the gear set to rotate, which in turn rotates the purification unit, achieving centrifugal force to separate the cells in the glass test tubes and achieve purification.

[0004] However, in the above-mentioned device, the components such as the spring supporting the positioning ring and positioning the glass test tube on both sides are incompatible and it is difficult to achieve the condensation and water separation of the purified substance. Therefore, we propose an electronic-grade nitrogen purification device that can condense and separate water from the purified substance. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an electronic-grade nitrogen purification device and method.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electronic-grade nitrogen purification device, comprising a placement plate, a filter tank disposed on the top of the placement plate, an air inlet formed on the circumferential surface of the filter tank, a vent pipe fixedly connected to the top of the filter tank, a molecular sieve drying box fixedly connected to one end of the vent pipe, a bottom of the molecular sieve drying box fixedly connected to the top of the placement plate, an air outlet pipe fixedly connected to the side of the molecular sieve drying box, a storage tank fixedly connected to the other end of the air outlet pipe, a bottom of the storage tank fixedly connected to the top of the placement plate, and a stirring and filtering device disposed inside the filter tank;

[0007] The stirring and filtering device includes a support plate, the bottom of which is fixedly connected to the top of the filter tank.

A fixing plate is fixedly connected to the circumferential surface of the rotating shaft. A driving strip is fixedly connected to the circumferential surface of the fixing plate. An activated carbon strip is fixedly connected to the top of the driving strip.

[0008] As described above, the filter canister is equipped with a filter inside, and an activated carbon sheet is fixedly connected inside the filter canister. The top of the activated carbon sheet penetrates the circumferential surface of the rotating shaft, and the inner wall of the activated carbon sheet is rotatably connected to the circumferential surface of the rotating shaft. The function of the filter is to remove large particulate impurities from the nitrogen gas, and the function of the activated carbon sheet is to further remove organic gases and odors from the nitrogen gas.

[0009] The aforementioned arrangement of several driving strips and activated carbon strips in a circular array along the circumference of the fixed plate is intended to improve nitrogen filtration.

[0010] As described above, a condensing device is provided at the bottom of the vent pipe. The condensing device includes a belt, the inner wall of which is driven to the circumferential surface of the rotating shaft. A rotating rod is driven to the inside of one end of the belt. A fixed plate is fixedly connected to the top of the molecular sieve drying box. The rotating rod is rotatably connected to the top of the fixed plate. A fan is fixedly connected to the top of the rotating rod. A condensing box is fixedly passed through the circumferential surface of the vent pipe. The function of the fan is to reduce the temperature of the condensing box and the vent pipe. The function of the condensing box is to condense and separate moisture.

[0011] As mentioned above, the top of the fan is located below the condenser box. The purpose of placing the top of the fan below the condenser box is to better cool the condenser box.

[0012] Compared with existing technologies, this electronic-grade nitrogen purification device and method have the following advantages:

[0013] I. This utility model achieves effective filtration of organic gases and odors from nitrogen in the filter canister by using the force of the rotating housing clamp to cooperate with components such as the rotating shaft, the fixed plate, the driving strip, and the activated carbon strip.

When the driving strip rotates, it drives the activated carbon strip to rotate.

This utility model achieves the effect of the rotating shaft force cooperating with the belt, rotating rod, fixed plate, fan, condenser box and other components, so that when the belt rotates, it drives the rotating rod to rotate, and when the rotating rod rotates, it drives the fan to rotate. When the fan generates air force, it cools the condenser box and the vent pipe, thereby reducing the gas temperature and causing the moisture to condense and separate.

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.

A fixing plate 84 is fixedly connected to the circumferential surface of the rotating shaft 83. A driving strip 85 is fixedly connected to the circumferential surface of the fixing plate 84. An activated carbon strip 86 is fixedly connected to the top of the driving strip 85.

[0026] The filter canister 2 is equipped with a filter 87, and an activated carbon sheet 88 is fixedly connected inside the filter canister 2. The top of the activated carbon sheet 88 extends through the circumference of the rotating shaft 83, and the inner wall of the activated carbon sheet 88 is rotatably connected to the circumference of the rotating shaft 83. The function of the filter 87 is to remove large particulate impurities from the nitrogen gas, and the function of the activated carbon sheet 88 is to further remove organic gases and odors from the nitrogen gas.

[0027] The number of driving strips 85 and activated carbon strips 86 are set to several and arranged in a ring array along the circumference of the fixed plate 84. The purpose of setting the number of driving strips 85 and activated carbon strips 86 to several and arranged in a ring array along the circumference of the fixed plate 84 is to better filter nitrogen.

[0028] First, when the operator needs to use this device to purify nitrogen, the stirring filter device 8 can be used to filter the nitrogen. Nitrogen is first delivered to the filter tank 2 through the air inlet 3. When the nitrogen passes through the filter 87, the filter 87 removes large particulate impurities in the nitrogen. Then, the motor 82 is started. When the output shaft of the motor 82 rotates, it drives the rotating shaft 83 to rotate. When the rotating shaft 83 rotates, it drives the fixed plate 84 to rotate. When the fixed plate 84 rotates, it drives the strip 85 to rotate. When the strip 85 rotates, it drives the activated carbon strip 86 to rotate, thereby removing organic gases and odors from the nitrogen in the filter tank 2. When the nitrogen enters the molecular sieve drying box 5 through the air pipe 4, it passes through the activated carbon sheet 88, thereby further filtering the nitrogen.

[0029] A condensing device 9 is installed at the bottom of the vent pipe 4. The condensing device 9 includes a belt 91. The inner wall of the belt 91 is connected to the circumferential surface of the rotating shaft 83. A rotating rod 92 is connected to the inner end of the belt 91. A fixed plate 93 is fixedly connected to the top of the molecular sieve drying box 5. The rotating rod 92 is rotatably connected to the top of the fixed plate 93. A fan 94 is fixedly connected to the top of the rotating rod 92. A condensing box 95 is fixedly passed through the circumferential surface of the vent pipe 4. The function of the fan 94 is to reduce the temperature of the condensing box 95 and the vent pipe 4. The function of the condensing box 95 is to condense and separate the moisture.

[0030] The top of the fan 94 is located below the condenser box 95. The purpose of placing the top of the fan 94 below the condenser box 95 is to better cool the condenser box 95.

[0031] A method of using an electronic-grade nitrogen purification device includes the following steps:

[0032] S1: First, when the operator needs to use this device to purify nitrogen, the stirred filter device 8 can be used to filter the nitrogen. The nitrogen is first delivered to the filter tank 2 through the air inlet 3.

[0033] S2: Start motor 82 to drive shaft 83 to rotate. When nitrogen enters molecular sieve drying box 5 through vent pipe 4, it will pass through activated carbon sheet 88, thus allowing for further filtration of nitrogen.

[0034] S3: The rotation of the rotating shaft 83 can drive the condensing device 9. When the rotating rod 92 rotates, it will drive the fan 94 to rotate. The air force generated by the fan 94 will cool the condensing box 95 and the vent pipe 4.

[0035] The fan 94 and activated carbon sheet 88 in S3 are model BLD-120 and 1.5mm respectively, and the internal temperature of the condenser box 95 is set to -30℃.

[0036] The rotation of the shaft 83 drives the condenser 9. When the shaft 83 rotates, it drives the belt 91 to rotate. When the belt 91 rotates, it drives the rotating rod 92 to rotate. When the rotating rod 92 rotates, it drives the fan 94 to rotate. The air force generated by the fan 94 cools the condenser 95 and the vent pipe 4 and starts the condenser 95. This reduces the temperature of the nitrogen passing through the vent pipe 4, causing its moisture to condense and separate.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
