Description

Technical Field

[0001] This utility model relates to the field of gas purification technology, and in particular to a high-efficiency adsorption tank structure for a gas purification device. Background Technology

[0002] Gas purification technology is widely used in key fields such as electronics and semiconductors, chemicals, and new energy (such as hydrogen energy). Its core function is to provide high-purity gases (such as high-purity hydrogen) for various industrial processes. As the core component of gas purification equipment, the adsorption tank mainly removes impurities such as moisture, oxygen, and hydrocarbons from the gas through the selective adsorption of adsorbents such as molecular sieves and palladium catalysts, thereby achieving deep purification of the gas.

[0003] In existing gas purification equipment, uneven airflow distribution occurs during use. Traditional adsorption tanks mostly adopt a "direct-in" air intake method, where gas directly impacts local areas of the adsorbent layer after entering the tank, which easily leads to airflow deviation. This problem prevents the adsorbent from being used evenly, resulting in unstable impurity removal and premature local saturation of the adsorbent, significantly shortening the adsorption cycle and affecting the overall purification efficiency of the equipment. Therefore, we propose a high-efficiency adsorption tank structure for gas purification equipment. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a high-efficiency adsorption tank structure for gas purification equipment. This structure can solve the problem of uneven airflow distribution in existing gas purification equipment during use. Traditional adsorption tanks mostly adopt a "direct-inlet" air intake method, in which gas directly impacts a local area of ​​the adsorbent layer after entering the tank, which easily leads to airflow deviation. This problem makes it impossible for the adsorbent to be used evenly, resulting in unstable impurity removal effect and causing the adsorbent to become locally saturated too quickly, significantly shortening the adsorption cycle and affecting the overall purification efficiency of the equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency adsorption tank structure for a gas purification device, comprising:

[0007] Gas guiding structure, which is located on the main body of the adsorption tank;

[0008] The gas guiding structure includes a rotating motor, a rotating shaft, a mounting cylinder, and a guide fan.

The guide fan is fixedly mounted on the outer surface of the mounting cylinder. A transmission box is fixedly sleeved on the outer surface of the adsorption tank body. A rotating rod is rotatably connected inside the transmission box. A stepper motor is fixedly mounted on one side of the transmission box. The output end of the stepper motor extends into the interior of the transmission box and is fixedly connected to the rotating rod.

[0009] Preferably, the gas guiding structure further includes multiple connecting rods, multiple guide plates, multiple bevel rings, and multiple bevel gears. The multiple connecting rods are rotatably connected to the inside of the adsorption tank body. The multiple guide plates are respectively fixedly sleeved on the outer surface of the corresponding connecting rods. One end of the multiple connecting rods rotatably extends into the inside of the transmission box and is fixedly connected to the corresponding bevel gear.

[0033] Support frame 7: Fixed inside the adsorption tank body 3, rotatably connected to the rotating shaft 6, providing support for the rotating shaft 6 and ensuring its stable rotation;

[0034] The guide fan 8 is fixed on the outer surface of the mounting cylinder 9 and rotates synchronously with the mounting cylinder 9 to generate airflow driving force, which uniformly guides the gas entering the adsorption tank body 3 to the core adsorption area.

[0035] Mounting sleeve 9: It is fixedly sleeved on the outer surface of the rotating shaft 6, connecting the rotating shaft 6 and the guide fan 8, so that the rotation of the rotating shaft 6 can drive the guide fan 8 to rotate.

[0036] Molecular sieve 10: There are two in total. They are installed inside the adsorption tank body 3 and come into contact with the uniformly flowing gas to adsorb residual moisture in the gas.

[0037] Transmission box 11: It is fixedly sleeved on the outer surface of the adsorption tank body 3, and internally rotatably connected to the rotating rod 13, providing installation and transmission space for the bevel ring 14 and bevel gear 15;

[0038] Stepper motor 12: Fixed on one side of transmission box 11, with its output end extending into the transmission box 11 and fixed to the rotating rod 13. After starting, it drives the rotating rod 13 to rotate according to preset parameters.

[0039] Rotating rod 13: Rotatably connected inside the transmission box 11, fixed to the output end of the stepper motor 12 and the bevel gear ring 14, transmitting the power of the stepper motor 12 to drive the bevel gear ring 14 to rotate;

[0040] Multiple bevel gear rings 14 are fixedly sleeved on the outer surface of the rotating rod 13 and mesh with the bevel gear 15. They rotate with the rotating rod 13 and drive the bevel gear 15 to rotate.

[0041] Multiple bevel gears 15, which respectively mesh with the corresponding bevel gear rings 14 and are fixed to the connecting rods 16. They are driven to rotate by the bevel gear rings 14, thereby driving the connecting rods 16 to rotate.

[0042] Connecting rod 16: Multiple rods are rotatably connected inside the adsorption tank body 3. One end extends to the transmission box 11 and is fixed to the bevel gear 15. The other end is connected to the guide plate 17 and drives the guide plate 17 to rotate.

[0043] Multiple guide plates 17 are fixed in a linear array on the outer surface of the corresponding connecting rod 16. They rotate with the connecting rod 16 to adjust the angle, precisely control the gas flow direction, and ensure that the gas is in full contact with the molecular sieve 10.

[0044] Example 1:

[0045] like Figure 1-4 As shown, the gas to be treated enters the adsorption tank body 3 through a pipeline. At this time, the output end of the rotating motor 5 drives the rotating shaft 6 to rotate. The mounting cylinder 9, which is fixedly sleeved on the outer surface of the rotating shaft 6, rotates synchronously with the rotating shaft 6, thereby driving the guide fan 8, which is fixedly installed on the outer surface of the mounting cylinder 9, to rotate. The rotation of the guide fan 8 generates airflow driving force, which evenly guides the gas entering the adsorption tank body 3 to the core adsorption area inside the adsorption tank body 3, preventing the gas from accumulating locally inside the tank and ensuring that the gas is initially evenly distributed.

[0046] During the gas flow towards the core adsorption region, the stepper motor 12 is activated. The output of the stepper motor 12 drives the rotating rod 13 to rotate. Multiple bevel gear rings 14, which are fixedly sleeved on the outer surface of the rotating rod 13, rotate synchronously with the rotating rod 13. Since multiple bevel gears 15 are respectively meshed with the corresponding bevel gear rings 14, the rotation of the bevel gear rings 14 drives the bevel gears 15 to rotate. The bevel gears 15 are fixedly connected to the connecting rod 16, which extends into the transmission box 11, thereby driving the connecting rod 16 to rotate inside the adsorption tank body 3. The guide plate 17, which is fixedly sleeved on the outer surface of the connecting rod 16, rotates synchronously with the connecting rod 16. Multiple guide plates 17 are arranged in a linear array inside the adsorption tank body 3. By adjusting the rotation angle of the guide plates 17, the gas flow direction is precisely controlled, so that the gas can contact the molecular sieve 10 inside the adsorption tank body 3 evenly and fully.

[0047] Example 2:

[0048] like Figure 3As shown, the support frame 7 provides stable support for the rotating shaft 6, effectively preventing the rotating shaft 6 from shaking or shifting during high-speed rotation, ensuring the stable operation of the guide fan 8, avoiding equipment failure caused by component shaking, and further ensuring the overall stability and safety of the equipment operation.

[0049] Furthermore, when using the device, before starting the equipment, the gas treatment parameters, including gas flow rate and adsorption time, are set through the control panel 4 installed on the top of the fixed base 1. After starting the equipment, the deoxygenation mechanism 2 first enters the working state to remove trace amounts of oxygen, which is a pretreatment for subsequent adsorption and drying. At the same time, the rotating motor 5 and the stepper motor 12 start according to the preset parameters.

[0050] The gas to be treated enters the adsorption tank body 3 through a pipeline. At this time, the output end of the rotating motor 5 drives the rotating shaft 6 to rotate. The mounting cylinder 9, which is fixedly sleeved on the outer surface of the rotating shaft 6, rotates synchronously with the rotating shaft 6, thereby driving the guide fan 8, which is fixedly installed on the outer surface of the mounting cylinder 9, to rotate. The rotation of the guide fan 8 generates airflow driving force, which evenly guides the gas entering the adsorption tank body 3 to the core adsorption area inside the adsorption tank body 3, preventing the gas from accumulating locally inside the tank and ensuring that the gas is initially evenly distributed.

[0051] As the gas flows towards the core adsorption area, the stepper motor 12 is activated. The output of the stepper motor 12 drives the rotating rod 13 to rotate. Multiple bevel rings 14, which are fixedly sleeved on the outer surface of the rotating rod 13, rotate synchronously with the rotating rod 13. Since multiple bevel gears 15 are respectively meshed with the corresponding bevel rings 14, the rotation of the bevel rings 14 drives the bevel gears 15 to rotate. The bevel gears 15 are fixedly connected to the connecting rod 16, which extends into the transmission box 11, thereby driving the connecting rod 16 to rotate inside the adsorption tank body 3. The guide plate 17, which is fixedly sleeved on the outer surface of the connecting rod 16, rotates synchronously with the connecting rod 16. Multiple guide plates 17 are arranged in a linear array inside the adsorption tank body 3. By adjusting the rotation angle of the guide plates 17, the gas flow direction is precisely controlled, so that the gas can come into uniform and sufficient contact with the molecular sieve 10 inside the adsorption tank body 3. During the contact process, the molecular sieve 10 adsorbs the residual moisture in the gas.

[0052] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
