[0004] The above-mentioned and existing technologies have the following defects: in the process of treating VOCs waste gas, when the carbon fiber adsorption plate needs to be maintained, the covered waste gas purification cylinder needs to be lifted so that foreign matter attached to the surface of the carbon fiber adsorption plate can be cleaned.

DETAILED DESCRIPTION

[0033] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0035] like Figure 1-Figure 6 As shown, the utility model provides an air purification device for VOCs waste gas treatment, including a purification tower 1 and a plurality of capture plates 6, the upper surface of the purification tower 1 is fixed with an air inlet pipe 2 and connected thereto, the side wall of the purification tower 1 is fixed with an exhaust pipe 3 and connected thereto, the inner wall of the purification tower 1 is fixedly connected with a water distribution pipe 4, the inner wall of the purification tower 1 is fixedly connected with a filter plate 5, the inner wall of the purification tower 1 is provided with a shaking structure 7, and the surface of the connecting pipe 75 is provided with a collecting structure 8.

[0036] The specific settings and functions of the shaking structure 7 and the collecting structure 8 are described in detail below.

[0037] like Figure 2-Figure 4As shown, the shaking structure 7 includes a rotating rod 71, which is rotatably connected to the purification tower 1, and the arc surface of the rotating rod 71 is fixedly connected to a fixed frame 72, and the inner wall of the fixed frame 72 is slidably connected to a sliding rod 73, and the sliding rod 73 is fixedly connected to the capture plate 6, and the inner wall of the purification tower 1 is fixedly connected to a protrusion 76, and the lower surface of the purification tower 1 is fixed and connected to a connecting pipe 75, and the lower surface of the purification tower 1 is fixedly connected to a motor 74, and the output end of the motor 74 is fixedly connected to the rotating rod 71, and the sliding rod 73 is a regular hexagonal prism structure, and the sliding rod 73 with a regular hexagonal prism structure can limit the moving path of the capture plate 6, and the arc surface of the rotating rod 71 is fixedly connected to a scraper 77, and the scraper 77 is connected to the purification tower 1. The tower 1 is slidably connected, and the scraper 77 rotates with the rotating rod 71 to push the particles along the bottom inner wall of the purification tower 1. The scraper 77 is an arc-shaped structure. By setting the scraper 77 to an arc-shaped structure, the particles can be pushed from the center of the bottom inner wall of the purification tower 1 to the edge during the process of pushing the particles, thereby facilitating the particles to slide into the connecting pipe 75. The surface of the sliding rod 73 is covered with a spring 78, and the two ends of the spring 78 are fixedly connected to the fixed frame 72 and the capture plate 6 respectively. When the capture plate 6 is out of contact with the protrusion 76, the capture plate 6 will slide back and forth in the vertical direction due to the elastic force of the spring 78, thereby accelerating the speed at which the particles fall off the surface of the capture plate 6.

[0038] like Figure 5 and Figure 6 As shown, the collecting structure 8 includes a card slot 81, which is provided on the surface of the connecting tube 75, and the inner wall of the card slot 81 is slidably connected with a card plate 82, and the lower surface of the card plate 82 is fixedly connected with a collecting box 83, and the collecting box 83 is communicated with the connecting tube 75. The side wall of the connecting tube 75 is rotatably connected with a baffle 84, and the baffle 84 reaches the position of limiting the card plate 82, thereby limiting the position of the collecting box 83, and the surface of the baffle 84 is fixedly connected with a magnetic block 85, and the card plate 82 is an iron plate. The rotation of the baffle 84 will cause the magnetic block 85 to contact the card plate 82. At this time, the magnetic block 85 will be attracted to the surface of the card plate 82 by its own magnetic force, and the magnetic block 85 reaches the position of limiting the baffle 84, thereby ensuring that the baffle 84 can normally limit the position of the card plate 82.

[0039] Its overall working principle is that when purifying VOCs waste gas, the VOCs waste gas is passed into the air inlet pipe 2, and the external water source is connected to the water distribution pipe 4. The particles in the VOCs waste gas will fall after being attached by water droplets, and the filter plate 5 will first perform preliminary treatment on the VOCs waste gas, and then the motor 74 will be turned on. The rotation of the output end of the motor 74 will drive the rotating rod 71 to rotate, and the rotation of the rotating rod 71 will drive the fixed frame 72 to move, and the movement of the fixed frame 72 will drive the sliding rod 73 to move, and the movement of the sliding rod 73 will drive the capture plate 6 to move, so that the capture plate 6 is used to capture and process the harmful substances in the VOCs waste gas. At the same time, the particles in the air will adhere to the surface of the capture plate 6, and when the capture plate 6 slides along the surface of the protrusion 76, the protrusion 76 will squeeze the capture plate 6 to move the capture plate 6 upward, and the movement of the capture plate 6 will drive the sliding rod 73 to move. The rod 73 slides along the inner wall of the fixed frame 72. At this time, the spring 78 located at the top will be compressed and the spring 78 located at the bottom will be stretched. When the capture plate 6 is out of contact with the protrusion 76, the capture plate 6 will slide back and forth in the vertical direction due to the elastic force of the spring 78, thereby accelerating the speed at which the particles fall off the surface of the capture plate 6 to ensure that the capture plate 6 can work normally. During this process, the sliding rod 73 with a regular hexagonal prism structure can limit the movement path of the capture plate 6. When the particles fall to the bottom inner wall of the purification tower 1, the scraper 77 follows the rotation of the rotating rod 71 to push the particles along the bottom inner wall of the purification tower 1. At the same time, by setting the scraper 77 into an arc structure, the particles can be pushed from the center of the bottom inner wall of the purification tower 1 to the edge during the process of pushing the particles, thereby facilitating the particles to slide into the connecting pipe 75.

[0040] When it is necessary to collect the particulate matter, the collection box 83 is moved. The movement of the collection box 83 will drive the card plate 82 to slide along the inner wall of the card slot 81, and the card slot 81 reaches the position of limiting the card plate 82, thereby limiting the position of the collection box 83. At this time, the collection box 83 will be aligned with the connecting tube 75, so the particulate matter can slide into the collection box 83 through the connecting tube 75. The collection box 83 will collect the particulate matter, thereby facilitating the centralized processing of the particulate matter. Thereafter, the baffle 84 is rotated, and the baffle 84 reaches the position of limiting the card plate 82, thereby limiting the position of the collection box 83. The rotation of the baffle 84 will cause the magnet 85 to contact the card plate 82. At this time, the magnet 85 will be attracted to the surface of the card plate 82 by its own magnetic force, and the magnet 85 reaches the position of limiting the baffle 84, thereby ensuring that the baffle 84 can normally limit the position of the card plate 82.

[0041] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
