Description

Technical Field

[0002] VOC purification devices can effectively remove volatile organic compounds from gases, enabling the gases to meet environmental emission standards.

[0003] Utility model patent CN213965878U discloses a VOC activated carbon purification device. Key technical features include: a shell, which is a hollow sphere with an air outlet at the top and rotating holes at the front and rear ends; a purification mechanism slidably connected inside the shell; a support mechanism fixed at the bottom; and collection and backflushing mechanisms symmetrically arranged on the left and right sides of the two shells. This device prevents leakage of toxic VOC gases during purification, achieving good purification effect and high efficiency. The rotating mechanism allows the gas channel to be rotated, and the activated carbon in the activated carbon cage is heated by microwave to restore its activity. No shutdown is required, ensuring continuous purification, high efficiency, and a high degree of automation. Sealed operation prevents VOC gases from harming human health and extends the lifespan of the activated carbon.

[0004] Regarding the above-mentioned issues, the following technical defects were found: When using a VOC purification device, the inlet pipe of the VOC purification device needs to be connected to the waste transmission pipe in order to introduce VOC-containing gas into the VOC purification device. However, different models of transmission pipes have different diameters, and the inlet pipe cannot be connected to transmission pipes of different models and diameters, which reduces the applicability of the VOC purification device.

[0005] Therefore, it is necessary to provide a new VOC purification device for gases to solve the above-mentioned technical problems. Summary of the Invention

[0031] In the embodiments of this utility model, please refer to Figure 2The docking assembly 3 includes a connecting cylinder 301, one end of which is fixedly connected to the air inlet pipe 5.

The center of the connecting ring 305, the center of the air inlet pipe 5, and the center of the gas transmission pipe 6 are all located at... Along the same straight line, several clamping plates 306 slide through the outer wall of the connecting ring 305. A sliding rod 307 is fixedly connected to one side of the clamping plate 306.

A gear 311 is fixedly connected to the output end of the servo motor 310. The gear 311 meshes with the toothed ring 308. By setting the docking assembly 3, VOC gas transmission pipes 6 of different diameters can be docked with the air inlet pipe 5 in the VOC purification device, thereby improving the applicability of the VOC purification device. A positioning plate 312 is fixedly connected to the outer wall of the connecting ring 305. A positioning rod 313 slides through the side of the positioning plate 312. One end of the short arm of the positioning rod 313 is fixedly connected to the outer wall of the connecting cylinder 301. When the connecting ring 305 moves, the positioning plate 312 fixed to the outer wall of the connecting ring 305 moves along the arc surface of the positioning rod 313, thereby improving the stability of the connecting ring 305 during movement.

[0032] In the embodiments of this utility model, please refer to Figure 3The lifting assembly 4 includes a base plate 41 and a lead screw 44. The upper end of the lead screw 44 is fixedly connected to the lower surface of the body 1. The lead screw 44 slides through the surface of the base plate 41. A driven wheel 43 is threadedly connected to the arc surface of the lead screw 44. The driven wheel 43 is rotatably connected to the lower surface of the base plate 41. Several support columns 42 are fixedly connected to the lower surface of the base plate 41. By setting the lifting assembly 4, the height of the VOC purification device can be adjusted, so that the air inlet pipe 5 in the VOC purification device can be connected to the gas transmission pipe 6 for conveying waste gas at different heights, thereby improving the applicability of the VOC purification device.

Several guide rods 49 are slidably inserted through the surface of the base plate 41. The upper end of the guide rods 49 is fixedly connected to the lower surface of the machine body 1, and the cross-section of the guide rods 49 is rectangular. When the lead screw 44 drives the machine body 1 to rise and fall, the guide rods 49 can guide and support the machine body 1, thereby improving the stability of the machine body 1 during the rising and falling process.

[0033] The working principle of the VOC purification device in the gas provided by this utility model is as follows: When it is necessary to purify VOCs in the gas, the gas is first introduced into the machine body 1 through the inlet pipe 5. The purification module in the machine body 1 can then purify the VOCs in the gas. When introducing the gas into the inlet pipe 5, a gas transmission pipe 6 needs to be connected to the inlet pipe 5. When it is necessary to connect gas transmission pipes 6 of different diameters to the inlet pipe 5, the gas transmission pipe 6 is first inserted into the connecting ring 305 and placed between the clamping plates 306. Then, the servo motor 310 is started to drive the gear 311 to rotate. The gear 311 drives the gear ring 308 to rotate. When the gear ring 308 rotates, the slide rod 307 slides along the inner wall of the sliding hole 309 on the gear ring 308. The slide rod 307 drives the clamping plates 306, causing several clamping plates 306 to move simultaneously towards the gas transmission pipe 6. When the clamping plates 306 drive the rubber pad 314 to abut and stabilize against the outer wall of the gas transmission pipe 6, the operation of the servo motor 310 can be stopped. Then, the electric motor 310 is started. Push rod 303 drives connecting ring 305, which in turn drives gas transmission pipe 6, which is securely clamped by clamping plate 306, to move towards the inner wall of connecting cylinder 301. When gas transmission pipe 6 abuts against the sealing sleeve 315 on the inner wall of connecting cylinder 301, the connection between gas transmission pipe 6, connecting cylinder 301, and inlet pipe 5 is completed. By setting connecting cylinder 301 as a frustum-shaped structure, the inner wall of connecting cylinder 301 can be connected to gas transmission pipes 6 of different diameters. During the movement of connecting ring 305... The positioning plate 312, fixed to the outer wall of the connecting ring 305, moves along the arc surface of the positioning rod 313, thereby improving the stability of the moving process of the connecting ring 305. In addition, the rubber pad 314 can increase the friction on one side of the clamping plate 306, thereby improving the limiting effect of the clamping plate 306 on the gas transmission pipe 6. Finally, the sealing sleeve 315 can block the tiny gap between the gas transmission pipe 6 and the connecting cylinder 301, thereby improving the sealing performance between the gas transmission pipe 6 and the connecting cylinder 301.

[0034] When the height of the VOC purification device needs to be adjusted, the drive motor 48 is started first to drive the drive wheel 45 to rotate. The drive wheel 45 drives the belt 46 to rotate. The belt 46 drives the driven wheel 43 to rotate. The driven wheel 43 drives the lead screw 44, which moves through the base plate 41. The lead screw 44 drives the machine body 1, thereby adjusting the height of the machine body 1. When the machine body 1 is adjusted to a suitable height, the operation of the drive motor 48 can be stopped. When the lead screw 44 drives the machine body 1 to rise and fall, the guide rod 49 can guide and support the machine body 1, thereby improving the stability of the machine body 1 during the rising and falling process.
