Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, specifically a filtration device for silicone sealant production. Background Technology

[0002] Silicone sealant is a paste-like material that hardens into a tough, rubber-like solid upon contact with moisture in the air. It is mainly classified into acetic acid-free, alcohol-free, ammonia-free, and propylene-free types. Because it is commonly used for bonding and sealing glass, it is commonly known as glass sealant. Single-component silicone glass sealant is a paste-like material that hardens into a tough, rubber-like solid upon contact with moisture in the air. During the production process, silicone sealant may clump, which affects filling and product quality. Therefore, it is necessary to remove lumps during production, requiring a filtration device for silicone sealant production.

[0003] For example, Chinese patent CN221207077U discloses a filtration device and apparatus for silicone sealant production, including a collection bucket, a rotatable filter barrel inside the collection bucket, a drive mechanism at the end of the filter barrel for driving the filter barrel to rotate, and a detachable filter element inside the filter barrel; the filter barrel includes a barrel body, a detachable end cap on one side of the barrel body, uniformly distributed limiting strips inside the barrel body, transverse grooves between the limiting strips, a slot corresponding to the limiting strips in the filter element, filter holes corresponding to the positions of the transverse grooves between the slots, and sealing rings at both ends of the filter element. This allows for easy replacement of the filter element while preventing the sealant from leaving residue.

[0004] Although the aforementioned patent has sealing rings at both ends of the filter element, which makes it easy to replace the filter element and prevents the residue from being left behind, the silicone sealant tends to adhere to the inner wall of the collection tank during filtration, making cleaning inconvenient and reducing its practicality.

[0028] In this embodiment, the silicone adhesive produced can be conveyed through the top of the feed pipe 510. Then, the motor 501 can be started, and the output shaft of the motor 501 drives the rotating rod 503 and the circular plate 504 to rotate. Then, the filter cylinder 505 and the connecting plate 509 can be rotated. The silicone adhesive inside the filter cylinder 505 generates centrifugal motion, and the produced silicone adhesive is thrown into the collection cylinder 2 through the filter cylinder 505. The lumps of silicone adhesive remain inside the filter cylinder 505.

[0029] In this embodiment, connecting frames 511 are provided on both the left and right sides of the circular plate 504, and scrapers 512 are provided on the opposite sides of the left and right connecting frames 511.

The silicone adhesive lumps remain inside the filter cylinder 505. By opening the solenoid valve in the discharge structure 7, the filtered silicone adhesive can be discharged from the inside of the collection cylinder 2. When the circular plate 504 rotates, it can drive the scrapers 512 on the left and right sides to rotate and scrape off the silicone adhesive adhering to the inner circumferential wall of the collection cylinder 2. After filtration, by simultaneously activating the electric push rods 601 on the left and right sides, the sealing plate 602 can be moved upward, and the connecting plate 509 can be moved upward.
