AI Technical Summary
Technical Problem
Existing exhaust gas purification devices suffer from air leakage when using the suction hood, causing some exhaust gas to drift into the outside environment and causing environmental pollution.
Method used
A sealing cover is installed at the bottom of the suction hood, and the sealing cover is tightly fitted to the worktable by the cooperation of the limiting component and the pressure plate to prevent air leakage.
Benefits of technology
This effectively prevents exhaust gas leakage, ensures that exhaust gas can completely enter the purification device, improves the purification effect, and protects the environment.

Abstract
This utility model relates to the field of halogen-free low-smoke sheath material production, specifically to a waste gas purification device for halogen-free low-smoke sheath material production. It includes a workbench, a granulator mounted on top of the workbench, an air suction hood above the granulator's exhaust port, a connecting pipe fixedly connected to the end of the air suction hood furthest from the granulator, and a purification device connected to the end of the connecting pipe furthest from the air suction hood. A sealing cover is mounted at the bottom of the air suction hood, and a limiting component is mounted on the outer wall of the connecting pipe. The limiting component includes a sleeve, a limiting part, a connecting rod, and a pressure plate. The sleeve is fitted over the connecting pipe, and the limiting part is fitted over the sleeve. This utility model, by mounting a sealing cover at the bottom of the air suction hood and a pressure plate on the sealing cover, uses the pressure plate to press against the workbench, causing the sealing cover to stretch, thereby covering the granulator and preventing air leakage.
