Two porous pressing plates are provided at both sides of a coal sample, and two metal filter plates are provided at both sides of the sample. Upper and lower openings of the reactor are sealed respectively with a connecting flange. The pressing plate above the sample is connected to a mounting baffle of a detection mechanism through a lightweight connecting rod and a spring. The detection mechanism is provided with a displacement sensor and a pressure sensor. This application further provides a detection method using the above device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Device for determining expansion pressure and expansion displacement generated by coking coal based on self-regulation of spring","description":"A device for determining an expansion pressure and an expansion displacement generated by coking coal based on self-regulation of a spring includes a pyrolysis reactor, which is provided in a high tem","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11242488","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
