Seeking advice on sealing issues with horizontal buried scraper feed plates
Thread Content
Horizontal buried scraper conveyors are used to transport powdered materials and feed them into multiple silos. Depending on the packaging requirements of each silo, it is necessary to switch between different silos for feeding. Currently, slide plates are used to adjust the size of the feeding openings; however, the sealing of these slide plates is not very tight, which results in powdered materials leaking through the gaps between them. I would like to know what type of \"slide plates\" is used by others to prevent leakage.
To address the sealing issue of the horizontal scraper discharge plug, the following methods can be employed: 1. **Improving the material**: Use wear-resistant and flexible rubber or silicone as the sealing material for the plug; such materials can provide a better fit between the plug and the silo, thereby reducing material leakage. 2. **Optimize the structure**: Design a plug system with a compression mechanism, such as by adding springs or pressure fine-tuning devices, to ensure that the plug fits tightly against the sealing surface of the silo opening. 3. **Use sealing strips**: Add sealing strips to the sides of the plug-in panel; these can be made of rubber, silicone, or foam material, etc., to fill in gaps and prevent materials from leaking out. 4. **Customized baffles**: Design specialized baffles based on the specifications of the silo to ensure the right dimensions and minimize gaps. 5. **Routine inspection and maintenance**: Regularly check for wear on the plugs and sealing areas, and replace any damaged parts promptly to maintain good sealing performance. These methods can help improve the sealing performance of the entire system and reduce the leakage of powdered materials. .
