The motor drives the reducer to output low-speed high torque, driving the rotating shaft or slewing support. Scraper\/blade tightly adheres to the cone wall or outlet section of the silo and performs low-speed circular motion (or reciprocating sliding), scraping against the silo wall and peeling off the sticky material. The scraper cuts into the interior of the material arch, damaging the stress points of the arch bridge and the internal friction between the materials, causing the bridge structure to collapse. The material is restored to its overall flow state, smoothly discharged by gravity, and no longer blocked. The effect is obvious for materials with high viscosity, high humidity, oil content, and easy agglomeration, while the wall vibrator and pneumatic arch breaking device often have little effect on such materials.\u3000\u3000\u7834\u62f1\u5668\u6750\u8d28\uff1a\u949b\u6750\uff0c\u4e0d\u9508\u94a2\u7cfb\u5217304.316L\uff0c2205.904.\u4e0e\u7269\u6599\u63a5\u89e6\u90e8\u5206\u886c\u9676\u74f7\u3001\u56db\u6c1f\uff0c\u55b7\u6d82\u9676\u74f7\u3001\u55b7\u6d82\u7279\u6c1f\u9f99\uff0c\u55b7\u6d82\u78b3\u5316\u94a8\u7b49\uff0c\u4e0e\u7269\u6599\u63a5\u89e6\u90e8\u5206\u4e0d\u9508\u94a2\uff0c\u78b3\u94a2\u7b49\u3002\u3000\u3000\u522e\u677f\u6837\u5f0f\uff1a\u4e00\u5b57\u578b\/\u76f4\u677f\u578b\uff0cF\u578b\u522e\u677f\u6837\u5f0f\uff0c\u53cc\u522e\u677f\u6837\u5f0f\u4ee5\u53ca\u4e0a\u4e0b\u522e\u677f\u6837\u5f0f\uff0c\u53ef\u6839\u636e\u6599\u4ed3\u6837\u5f0f\u5b9a\u5236\u89d2\u5ea6\uff0c\u6216\u5ba2\u6237\u6307\u5b9a\u6837\u5f0f\u3002\u3000\u3000\u7834\u62f1\u5668\u5c3a\u5bf8\uff1aDN50~DN1500.\u6216\u975e\u6807\u5b9a\u5236\u3002\u3000\u3000\u5bc6\u5c01\u65b9\u5f0f\uff1a\u91c7\u7528\u673a\u68b0\u5bc6\u5c01\u548c\u6c14\u5bc6\u5c01\u591a\u79cd\u5bc6\u5c01\u65b9\u5f0f\uff0c\u9632\u6b62\u7269\u6599\u8fdb\u5165\u4f20\u52a8\u88c5\u7f6e\u3002\u3000\u3000Material of arch breaker: titanium, stainless steel series 304.316L, 2205.904.

The core principle of the scraper rotary valve is to feed the material quantitatively through the rotation of the valve core, and at the same time, use a follow-up scraper to scrape off the material remaining on the inner wall of the rotor hopper, preventing the bridging and accumulation of viscous and moisture absorbing materials. \u200c\u200c\u3000\u3000The scraper is connected to the valve core through a transmission mechanism and rotates synchronously, scraping the inner wall of the material receiving groove in real time to remove the attached material and avoid it sticking to the groove wall or the cavity between the blades that cannot be discharged. \u200c\u200c\u3000\u3000\u90e8\u5206\u5ba2\u6237\u9700\u6c42\uff1a\u3000\u3000\u7834\u62f1\u9600+\u661f\u578b\u5378\u6599\u5668\u3002\u7b52\u4ed3\u6750\u8d28\uff1a\u63a5\u89e6\u7269\u6599\u90e8\u5206S30408.\u5185\u90e8\u629b\u5149Ra:0.4\u03bcm\u3002\u6599\u4ed3\u5bb9\u79ef8m\u00b3\uff0c\u5c3a\u5bf8\u03a61900*2270.\u8bbe\u8ba1\u6e29\u5ea60-100\u2103\uff0c\u8bbe\u8ba1\u538b\u529b-100Kpa~100Kpa;DN150\u7834\u62f1\u5668\uff0c\u68c0\u4fee\u95e8\u52a0\u5f3a\uff0c\u65e0\u53d8\u5f62\u6f0f\u6c14\uff0c\u6f0f\u6599\u73b0\u573a\uff0c\u9664\u5c18\u5668\u9876\u76d6\u3001\u7b52\u58c1\u52a0\u5f3a\u8bbe\u8ba1\u3002\u65cb\u8f6c\u7834\u62f1\u9600\u63a5\u89e6\u7269\u6599\u90e8\u5206S30408;\u7834\u62f1\u9600\u62e8\u6746\u629b\u5149Ra:0.2.\u7834\u62f1\u9600\u4e0b\u65b9\u914d\u5907DN150\u5378\u6599\u5668\uff0c\u53f6\u7247\u629b\u5149Ra0.2.\u5378\u6599\u9600\u4e0b\u7aef\u8fde\u63a5\u505a\u63d0\u4f9b\u914d\u5957\u6cd5\u5170:\u51cf\u901f\u673a\u914d\u5e26\u786c\u9f7f\u8f6e\u51cf\u901f\u673a\uff0c\u7535\u673a\u53d8\u9891\uff0c\u9632\u7206\u7b49\u7ea7ExdIIBT4\u9632\u62a4\u7b49\u7ea7:IP55.\u6599\u4ed3\u5de5\u827a\u53c2\u6570\u63a5\u5165DCS(\u538b\u529b\u3001\u884c\u661f\u4e0b\u6599\u9600\u548c\u7834\u62f1\u5668\u8fd0\u884c\u72b6\u6001)\u8109\u51b2\u5439\u626b\u914d\u5e26\u63a7\u5236\u7bb1\u3002\u3000\u3000Partial customer requirements:\u3000\u3000Arch breaking valve+star shaped unloader.
