Description

Technical Field

[0001] This utility model relates to the technical field of ventilation equipment, specifically to a cleanroom ventilation equipment. Background Technology

[0002] During the production process in a cleanroom, various dusts, harmful gases, and harmful substances are inevitably generated. To prevent them from spreading or causing pollution in the cleanroom, ventilation measures are generally taken to expel the pollutants outdoors.

[0003] In existing technology, the exhaust system is installed on the outer wall of the cleanroom. The rotation of the fan removes dust and harmful gases from the cleanroom, preventing their spread and contamination.

[0004] Existing technology utilizes a built-in fan to expel dust and harmful gases from the cleanroom. During the expulsion process, the exhaust gas is filtered by a built-in filter plate. However, after exhaust, dust and harmful substances adhere to the filter plate, affecting the overall ventilation effect of the equipment and making it difficult to clean. Its practicality needs to be improved.

[0005] Therefore, this utility model proposes a cleanroom exhaust ventilation device. Utility Model Content

[0025] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0026] See Figure 1-3As shown, a cleanroom exhaust system includes an exhaust main pipe 1 and air inlet hoods 2 and air supply grilles 4 at both ends. An inner mounting platform 6 is fixedly connected inside the air inlet end of the exhaust main pipe 1. An exhaust detection chamber 3 is provided inside the air supply end of the exhaust main pipe 1. A detection mechanism 5 is fixedly connected to the top of the exhaust detection chamber 3. A matching mounting frame 7 and filter plate assembly 8 are fixedly connected to the inner side of the inner mounting platform 6. A carbon plate 9 is embedded in the inner side of one end of the mounting frame 7. A flow guide assembly 10 is fixedly connected to one end of the mounting frame 7, and a base plate 15 is fixedly connected to the bottom of the other end. An air supply grid 4 is fixedly connected inside the air supply end of pipe 1. The filter plate assembly 8 includes a filter plate body 11 and a cleaning plate 14. A drive assembly 13 is fixedly connected to one end of the cleaning plate 14. Drive tooth grooves 12 are opened on both sides of the filter plate body 11. The drive assembly 13 and the drive tooth grooves 12 are movably fitted together. The flow guiding assembly 10 includes a flow guiding mounting frame 16 and a first flow guiding hood 17, a suction mechanism 18 and a second flow guiding hood 19 that are matched inside it. The first flow guiding hood 17, the suction mechanism 18 and the second flow guiding hood 19 are fixedly connected in sequence.

[0027] In this embodiment of the utility model, the mounting frame 7 is a three-sided rectangular frame, with its longitudinal sides and air inlet end open. The base plate 15 is fixedly connected to the bottom of the air inlet end of the mounting frame 7, and the base plate 15 is also movably embedded in the inner mounting platform 6. The inner sides of the air inlet end of the mounting frame 7 are provided with slots corresponding to the upper and lower ends of the filter plate assembly 8. The carbon plate 9 is rectangular and fixedly connected to the center of the air supply end of the mounting frame 7. The filter plate body 11 consists of a set of arc-shaped frames and arc-shaped filter plates on its inner side. The drive tooth groove 12 is opened through the arc-shaped frames, and the bottom surface of the drive tooth groove 12 is toothed and concave. The drive assembly 13 consists of a set of cylindrical shells and a drive motor inside it. The surface of the cylindrical shells is provided with toothed protrusions corresponding to the drive tooth groove 12. The drive motor is equipped with a drive shaft. The cleaning plate 14 is fixedly connected to one end of the filter plate body 11, and the cleaning plate 14 is located on the inner surface of the filter plate body 11. The end of the cleaning plate 14 opposite to the drive assembly 13 is simultaneously movably embedded in the corresponding drive tooth groove 12. The surface of the cleaning plate 14 is provided with a brush layer. The mounting frame 7 facilitates the overall installation and fixing of the filter plate assembly 8 and the carbon plate 9. The base plate 15 ensures the stable installation of the mounting frame 7 in the exhaust body 1.

The drive assembly 13 drives the cleaning plate 14 to move and adjust. The cleaning plate 14 moves along the surface of the filter plate body 11 to perform cleaning.

[0028] When filtering external airflow, the external airflow first enters the exhaust duct 1 through the air inlet hood 2, and the filter plate body 11 performs initial filtration. Then, the airflow passes through the carbon plate 9 for further purification. When it is necessary to clean the surface of the filter plate body 11, the drive assembly 13 is activated, which drives the cleaning plate 14 to move along the drive tooth groove 12 and rotate, thereby cleaning the residual dust and impurities on the surface of the filter plate body 11.

The airflow guide frame 16 facilitates the installation and fixing of the first airflow guide shroud 17, the second airflow guide shroud 19 and the suction mechanism 18. The first airflow guide shroud 17, which is attached to the carbon plate 9, ensures a sealed airflow effect.

[0030] When the suction mechanism 18 is activated, the airflow that has been filtered by the carbon plate 9 is discharged outward along the first guide shroud 17 and the second guide shroud 19. When the discharged airflow passes through the discharge detection chamber 3, it is detected by the detection mechanism 5.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
