Description

Technical Field

[0001] The utility model relates to the technical field of ventilation duct filtration, and particularly relates to a ventilation duct filtration structure for a clean room. Background Art

[0002] The ventilation duct for a clean room is a ventilation system designed to maintain a dust-free environment, mainly used for effectively discharging and filtering particles, pollutants, and microorganisms in the air. It ensures that the indoor environment meets specific cleanliness standards by circulating air and is widely used in industries such as electronics, pharmaceuticals, and biotechnology. The ventilation duct is usually equipped with a filter element to remove dust particles and keep the air clean. In addition, the design of this system also considers the uniformity of air flow to reduce dead corners and pollution sources, ensuring the working efficiency and safety of the clean room.

[0003] Although the existing ventilation duct can filter dust particle impurities in the air through its related filter element, thus achieving the effect of purifying the air, after the filter element is used for a certain period of time, it will also be blocked due to a large amount of dust impurity particles remaining on the surface filtration. Generally, it is inconvenient to detect and handle the blockage of the filter element of the existing ventilation duct in a timely manner, which will correspondingly affect the ventilation effect of the clean room.

[0004] In view of this, we propose a ventilation duct filtration structure for a clean room. Content of the Utility Model

The scraper can be driven by the driving member to move along the surface of the filter plate, and at the same time, the sealing cover is driven to move to one side.

[0011] Further, the driving member includes two sets of push-pull rods rotatably mounted on the top of the sealing cover. At the ends of the two sets of push-pull rods away from the sealing cover, a scraper is rotatably mounted, and a threaded sleeve and a slider are respectively fixedly mounted at both ends of the scraper.

[0025] In order to make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0026] The present utility model will be further described below with reference to the embodiments.

[0027] Embodiment: A dust-free room ventilation pipeline filtering structure includes a pipeline body 1 and a chip collection box 2 fixedly installed at the bottom of the pipeline body 1. A fixed frame 6 is fixedly installed on the inner cavity side wall of the pipeline body 1. A filter plate 7 is fixedly installed on the inner cavity side wall of the fixed frame 6. And a scraper 11 for cleaning the surface of the filter plate 7 is arranged on one side of the filter plate 7. Among them, a sealing cover 5 for sealing the chip collection box 2 is arranged on the top of the chip collection box 2. And a driving member is arranged on the top of the sealing cover 5. The scraper 11 can be driven to move along the surface of the filter plate 7 through the driving member, and at the same time, the sealing cover 5 is driven to move to one side. Two air flow sensors are also fixedly installed inside the pipeline body 1, and the two air flow sensors are respectively arranged on both sides of the filter plate 7, and are used for the air flow of the pipeline body 1 section before passing through the filter plate 7 and the air flow of the pipeline body 1 section after passing through the filter plate 7;

[0028] By respectively arranging air flow sensors on both sides of the filter plate 7, the air flow of the pipe body 1 section before passing through the filter plate 7 and the air flow of the pipe body 1 section after passing through the filter plate 7 can be detected by the two groups of flow sensors. By comparing the flow data measured by the two sensors, the influence of the filter structure on the air flow can be intuitively understood. When the air flow passing through the filter plate 7 is significantly less than the air flow of the pipe body 1 section before passing through the filter plate 7, it can be determined that the filter plate 7 is blocked. Then, by using the provided driving member, the scraping plate 11 is driven to move along the surface of the filter plate 7 to scrape off the dust particle impurities remaining on its surface. And while the scraping plate 11 is moving, the driving member can also move and open the sealing cover 5 above the chip collecting box 2, so that the scraped dust impurity particles can be directly scraped into the chip collecting box 2, thus facilitating the centralized collection and treatment of the cleaned dust impurity particles;

[0029] Specifically, the driving member includes two groups of push-pull rods 9 rotatably installed on the top of the sealing cover 5. One ends of the two groups of push-pull rods 9 away from the sealing cover 5 are rotatably installed with a scraping plate 11. Threaded sleeves 13 and sliders 10 are respectively fixedly installed at both ends of the scraping plate 11. A sliding rod 8 is slidably installed on the inner cavity side wall of the slider 10, and both ends of the sliding rod 8 are fixedly installed on the inner cavity side wall of the pipe body 1. A lead screw 12 is threadedly connected to the inner cavity side wall of the threaded sleeve 13. The bottom of the lead screw 12 is fixedly installed on the inner cavity bottom of the pipe body 1, and the top of the lead screw 12 rotates through the pipe body 1. A motor 3 is fixedly installed on the top of the pipe body 1, and the motor 3 is fixedly installed on the top of the lead screw 12 through an output shaft. Two groups of chutes 4 are opened on the inner cavity side wall of the pipe body 1, and the inner cavity side walls of the two groups of chutes 4 are slidably connected to the surface of the sealing cover 5;

[0030] Specifically, when it is detected that the filter plate 7 is blocked, the motor 3 can be driven to drive the lead screw 12 to rotate. Due to the guiding and limiting action of the sliding rod 8 on the slider 10, when the lead screw 12 rotates, the scraping plate 11 can be driven to move downward along the surface of the filter plate 7 through the slider 10 and the threaded sleeve 13, so as to scrape off the dust particle impurities and the like remaining on its surface. And when the scraping plate 11 moves downward, the sealing cover 5 in the chute 4 can be driven to move to one side through the two groups of push-pull rods 9, so as to open the chip collecting box 2, and the scraped dust impurity particles can enter the chip collecting box 2. Vice versa, when the surface of the filter plate 7 is cleaned and the scraping plate 11 and the sealing cover 5 need to be reset, only the rotation direction of the output shaft of the motor 3 needs to be adjusted to make the lead screw 12 rotate in the reverse direction.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
