\n\t\t\t\t\t\t\t\t\t\u3000\u3000The core logic of the scraping and breaking arch valve does not rely on vibration or airflow impact, but rather uses mechanical force to forcefully break the “arch bridge” built by the material. The motor drives the transmission structure (commonly gears or vortex rods) to operate, transmitting power to the scraper. The scraper is installed at the bottom of the silo and moves in a circular motion around the silo wall, continuously rotating against the bottom of the material pile up. The rotating scraper directly cuts and agitates the bottom of the material, breaking the arch structure formed by the mutual support between the material particles. At the same time, it can also scrape off the material stuck to the warehouse wall, allowing the material to fall again under the action of gravity. \u200c\u200c\u3000\u3000\u522e\u6599\u7834\u62f1\u9600\u6838\u5fc3\u903b\u8f91\u4e0d\u9760\u632f\u52a8\u3001\u4e5f\u4e0d\u9760\u6c14\u6d41\u51b2\u51fb\uff0c\u800c\u662f\u7528\u673a\u68b0\u529b\u786c\u6027\u7834\u9664\u7269\u6599\u642d\u8d77\u6765\u7684\u201c\u62f1\u6865\u201d\u3002\u7535\u673a\u5e26\u52a8\u4f20\u52a8\u7ed3\u6784(\u5e38\u89c1\u7684\u662f\u9f7f\u8f6e\u6216\u6da1\u6746)\u8fd0\u8f6c\uff0c\u628a\u52a8\u529b\u4f20\u7ed9\u522e\u677f\u3002\u522e\u677f\u5b89\u88c5\u5728\u6599\u4ed3\u5e95\u90e8\uff0c\u7ed5\u7740\u4ed3\u58c1\u505a\u5706\u5468\u8fd0\u52a8\uff0c\u8d34\u7740\u7269\u6599\u5806\u79ef\u7684\u5e95\u90e8\u6301\u7eed\u65cb\u8f6c\u3002\u65cb\u8f6c\u7684\u522e\u7247\u76f4\u63a5\u5207\u65ad\u3001\u6405\u52a8\u7269\u6599\u5e95\u90e8\uff0c\u7834\u574f\u7269\u6599\u9897\u7c92\u4e4b\u95f4\u76f8\u4e92\u652f\u6491\u5f62\u6210\u7684\u62f1\u5f62\u7ed3\u6784\uff0c\u540c\u65f6\u4e5f\u80fd\u522e\u6389\u9ecf\u5728\u4ed3\u58c1\u4e0a\u7684\u6599\uff0c\u8ba9\u7269\u6599\u5728\u91cd\u529b\u4f5c\u7528\u4e0b\u91cd\u65b0\u4e0b\u843d\u3002\u200c\u200c\u3000\u3000\u6a61\u80f6\u884c\u4e1a\uff0c\u7269\u6599\uff1a\u6a61\u80f6\u578b\u7c89\u4f53\u9897\u7c92\uff0c\u522e\u6599\u7834\u62f1\u9600\u5c3a\u5bf8DN250 PN10 \u6750\u8d28304.\u522e\u6599\u5668\u65cb\u8f6c\u90e8\u4ef6\u5bc6\u5c01\u5904\u5e94\u5728\u7acb\u9762\uff0c\u9632\u6b62\u7269\u6599\u7ec6\u9897\u7c92\u8fdb\u5165\u3002\u8f6c\u52a8\u90e8\u5206\u52a0\u88c5\u538b\u7f29\u7a7a\u6c14\u98ce\u53e3\uff0c\u5229\u7528\u538b\u7f29\u7a7a\u6c14\u9632\u6b62\u7ec6\u6599\u8fdb\u5165\u30022.2KW\u9632\u7206\u7535\u673a\uff0c\u54c1\u724c\u7696\u5357\/\u5357\u9633\/\u6c5f\u82cf\u5927\u4e2d\u7b49\u3002\u51cf\u901f\u673a\u4e3a\u4e00\u7ebf\u54c1\u724c\uff0c\u7834\u62f1\u9600\u8f93\u51fa\u8f6c\u901f\u4e3a3-4r\/min\uff0c\u8f93\u51fa\u626d\u77e9\u4e0d\u5c0f\u4e8e2390Nm\u3002\u3000\u3000Rubber industry, material: rubber powder particles, scraper arch breaking valve size DN250 PN10 material 304. scraper rotating parts sealing should be on the facade to prevent fine particles from entering.
