Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of adsorption devices, specifically to a kind of compressed air runner adsorption device. BACKGROUND

[0002] Due to the compressibility of air, the air after mechanical work by air compressor to make the volume shrink, the pressure is improved, which is called compressed air. Compressed air is an important power source. Because air contains organic matter and gas molecules, such as oil mist, which can affect the quality of compressed air, so in the preparation process of compressed air, air needs to be adsorbed.

[0003] The core of the runner adsorption principle is to realize the adsorption-regeneration cycle by the physical adsorption characteristics of special materials combined with the rotation of the runner, so as to achieve the purpose of continuously removing the target components in the gas or air. For example, Chinese patent document CN115318064B discloses a zeolite runner adsorption device, which comprises a runner cover, and the inner wall of the runner cover is rotatably installed with a zeolite runner. The zeolite runner comprises a support frame, and the middle part of the support frame is fixedly installed with a cleaning mechanism. The cleaning mechanism comprises a cleaning pipe, and the middle part of the cleaning pipe is fixedly connected with a plurality of evenly arranged shunt pipes. One end of the cleaning pipe is rotatably connected with an air pipe. A plurality of side air vents are formed in the edge of the support frame, and a plurality of air extraction pipes are fixedly connected to the bottom edge of the runner cover. By arranging the air extraction pipes and a plurality of side air vents, the zeolite runner is subjected to different directions of suction force when working, so that the exhaust gas entering the zeolite runner can spread in different directions, and the exhaust gas can be more fully contacted with the zeolite runner, improving the utilization rate of each part of the zeolite runner and the adsorption efficiency of the exhaust gas.

[0004] In the prior art described above, the rotating runner is used to adsorb and purify the gas. However, it is found that the runner is easy to wear during driving the runner to rotate, which reduces the service life of the runner and affects the adsorption effect of the gas. UTILITY MODEL CONTENTS

[0005] The utility model discloses in order to solve the technical problem that adsorption runner is easy to wear in the prior art, provides a kind of compressed air runner adsorption device, including the jar body being equipped with adsorption runner, and the shaft is arranged in the jar body along the axial direction, and adsorption runner is sleeved on the shaft, still include the power structure of driving adsorption runner rotation;Wherein: power structure is located at one side of adsorption runner, and power structure includes transmission part and power piece, and one end of transmission part is arranged on the circumferential periphery of adsorption runner, and the other end of transmission part is arranged on the output end of power piece.

[0006] In existing technologies, most methods involve a drive motor directly driving a reducer, which in turn drives a central shaft to rotate the adsorption wheel. The central shaft needs to pass through the upper or lower housing to connect with the reducer motor. To ensure normal rotation of the wheel after transmission, the concentricity of the central shaft must be controlled. This requires high precision in the machining of the welded and assembled housing openings; otherwise, the following problems may easily occur: poor dynamic sealing; the wheel rotating at an angle, causing wear and resulting in poor sealing of the wheel surface and air leakage, thus failing to guarantee the adsorption and drying effect; the reducer may also be unable to be installed or may be misaligned after installation, forcing operation and affecting the lifespan of the reducer, thereby reducing the overall lifespan of the adsorption wheel.

[0007] In this solution, a lateral transmission method is used instead of the direct shaft transmission method in the prior art. On the one hand, it can reduce the installation requirements of the drive motor and the rotating shaft. On the other hand, the direct shaft connection method in the prior art makes the speed of the drive motor and the adsorption wheel the same. Therefore, in order to achieve the ultra-low speed rotation of the adsorption wheel, a multi-stage reducer is required, which is complex. In this solution, the transmission component drive method can achieve ultra-low speed operation without reducing the speed of the power component, and can also reduce the cost of the device.

[0008] Preferably, the output end of the power component is equipped with a transmission sprocket, and the transmission component is a chain that cooperates with the transmission sprocket. This design has a simple structure and can reduce the cost of the device.

[0009] Preferably, the drive sprocket is a double-row sprocket. In this design, the double-row sprocket reduces the probability of chain slippage, thereby ensuring the normal operation of the drive wheel.

[0010] Preferably, the power structure is mounted on the outer surface of the tank. This design facilitates the assembly and maintenance of the power structure.

[0011] Preferably, an installation branch pipe is installed on the outer surface of the tank body. One end of the transmission component extends out of the tank body and into the installation branch pipe, and the output end of the power component extends into the installation branch pipe. In this design, the installation branch pipe provides an installation position for the power structure and also protects the transmission sprocket and the portion of the chain extending out of the tank body.

[0012] Preferably, a flange structure is provided at the end of the installation branch pipe away from the tank body. In this design, the flange structure can achieve pressure sealing of the installation branch pipe on the one hand, and facilitate opening for maintenance of the internal drive sprocket on the other.

[0013] Preferably, the power component is fixed to the mounting branch pipe via a flange. In this design, the flange provides a mounting location for the power component and also serves to seal the mounting branch pipe.

[0014] Preferably, the flange is provided with a rotary seal, and the output shaft of the power component penetrates the rotary seal. In this scheme, the rotary seal can play a dynamic sealing role, further ensuring the sealing performance of the installation branch pipe.

[0015] Preferably, the distal end of the output shaft is provided with a fixing component. In this scheme, the fixing component can achieve fastening connection of the transmission sprocket on the output shaft, preventing the transmission sprocket from falling off.

[0016] Preferably, the two ends of the rotating shaft are provided with bearings made of corrosion-resistant materials. This scheme can further ensure the normal operation of the adsorption runner.

[0017] The utility model has the following beneficial effects:

[0018] 1. The utility model adopts a lateral transmission mode to replace the direct shaft transmission driving mode in the prior art. On the one hand, the installation requirements of the driving motor and the rotating shaft can be reduced. On the second hand, the direct shaft connection mode in the prior art makes the rotating speeds of the driving motor and the adsorption runner consistent. Therefore, in order to realize the ultra-low speed rotation of the adsorption runner, a multi-stage speed reducer is needed to achieve the structure, which is complex and has a high cost of the device. In the utility model, the driving mode of the transmission component can realize the ultra-low speed rotation of the rotating speed without reducing the rotating speed of the power component, and can also reduce the cost of the device.

[0019] 2. The utility model also facilitates the installation and maintenance of the power structure, and protects the transmission component.

[0020] 3. The utility model can also ensure the sealing performance of the tank body. BRIEF DESCRIPTION OF DRAWINGS
