After the material absorbs moisture, a water film forms on the surface, and "liquid bridge force" or even "crystal bridge" is generated between particles, which "welds" adjacent particles together; Slight moisture can cause the powder to clump together, exacerbating bridging.　　如何解决物料架桥、结块、堵塞不下料?　　机械式刮料破拱阀破除架桥效果极 佳。电机带动减速机，输出低速大扭矩，驱动旋转轴或回转支承。刮板/刮片紧贴料仓锥壁或出口段做低速圆周运动(或往复滑动)，贴着仓壁刮擦，剥离粘壁物料。刮板切入料拱内部，破坏拱桥的受力点和物料间的内摩擦，让架桥结构垮塌。物料恢复整体流状态，靠重力顺利排出，不再堵塞。对高粘、高湿、含油、易结块的物料效果明显，仓壁振动器和气动破拱装置对这类物料常常效果甚微。　　How to solve material bridging, agglomeration, and blockage that prevent material from being discharged?　　The mechanical scraping arch breaking valve has excellent bridge breaking effect. 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.　　破拱器材质：钛材，不锈钢系列304.316L，2205.904.与物料接触部分衬陶瓷、四氟，喷涂陶瓷、喷涂特氟龙，喷涂碳化钨等，与物料接触部分不锈钢，碳钢等。　　刮板样式：一字型/直板型，F型刮板样式，双刮板样式以及上下刮板样式，可根据料仓样式定制角度，或客户指定样式。　　破拱器尺寸：DN50~DN1500.或非标定制。　　密封方式：采用机械密封和气密封多种密封方式，防止物料进入传动装置。　　Material 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. ‌‌　　The 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. ‌‌　　部分客户需求：　　破拱阀+星型卸料器。筒仓材质：接触物料部分S30408.内部抛光Ra:0.4μm。料仓容积8m³，尺寸Φ1900*2270.设计温度0-100℃，设计压力-100Kpa~100Kpa;DN150破拱器，检修门加强，无变形漏气，漏料现场，除尘器顶盖、筒壁加强设计。旋转破拱阀接触物料部分S30408;破拱阀拨杆抛光Ra:0.2.破拱阀下方配备DN150卸料器，叶片抛光Ra0.2.卸料阀下端连接做提供配套法兰:减速机配带硬齿轮减速机，电机变频，防爆等级ExdIIBT4防护等级:IP55.料仓工艺参数接入DCS(压力、行星下料阀和破拱器运行状态)脉冲吹扫配带控制箱。　　Partial customer requirements:　　Arch breaking valve+star shaped unloader.

The arch breaking device generally uses two rotating arch breaking shafts or mechanical stirring to periodically impact the bottom of the silo and dynamically break the clumping structure.　　Conveyor link: The motor drives the spiral shaft to rotate, and the spiral blades generate propulsion force. The material relies on its own gravity and friction with the groove wall, and does not rotate with the blades, but is continuously pushed forward along the groove bottom until it is discharged from the discharge port. Support horizontal, inclined, or vertical operations.　　Modular components: including silos, screw shafts, drive devices, sealing structures, and auxiliary arch breaking components, supporting linkage with equipment such as sorting valves and vacuum feeders.　　The two should be coordinated: the arch breaking action and the unloading/conveying action should be carried out simultaneously, otherwise if the arch is broken in the front and not conveyed in the back, the material will quickly re compact and form an arch. ‌‌Dual axis reverse rotation reduces material accumulation and clumping, suitable for high viscosity and easy to plate materials (such as lithium battery positive and negative electrode materials).　　精准控制给料量：　　变频调节：通过变频电机控制螺旋转速，实现流量无级调节(0.5-60吨/小时)，误差≤±0.5%。　　失重计量：可选配失重称量系统，实时监测物料重量，动态调整给料量。　　密封与防污染：　　气密性设计：耐压0.3MPa，支持正负压输送，防止粉尘泄漏或外部污染。　　防粘涂层：螺旋轴及槽体表面喷涂PTFE或WC耐磨涂层，减少物料残留。　　Accurate control of feeding quantity:　　Variable frequency regulation: The spiral speed is controlled by a variable frequency motor to achieve stepless flow regulation (0.5-60 tons/hour) with an error of ≤± 0.5%.　　Weight loss measurement: An optional weight loss weighing system can be used to monitor material weight in real-time and dynamically adjust the feeding amount.　　Sealing and Pollution Prevention:　　Airtight design: withstand pressure of 0.3MPa, support positive and negative pressure conveying, prevent dust leakage or external pollution.　　Anti stick coating: PTFE or WC wear-resistant coating is sprayed on the surface of the spiral shaft and groove to reduce material residue.　　常州同得利公司在强化企业管理的基础上，依靠科技进步提高技术含量，先进的生产加工设备，优质的管理理念，高素质的员工团队，有效的质量保障体系和完善的售后服务，为制造高品质的产品提供可靠的保证，极大的满足了各行业的需求，深受广大客户的信赖。　　On the basis of strengthening enterprise management, Changzhou Tongdeli Company relies on technological progress to improve its technical content, advanced production and processing equipment, high-quality management concepts, a high-quality employee team, an effective quality assurance system, and perfect after-sales service, providing reliable guarantees for manufacturing high-quality products, greatly meeting the needs of various industries, and deeply trusted by customers.

　　The 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. ‌‌　　刮料破拱阀核心逻辑不靠振动、也不靠气流冲击，而是用机械力硬性破除物料搭起来的“拱桥”。电机带动传动结构(常见的是齿轮或涡杆)运转，把动力传给刮板。刮板安装在料仓底部，绕着仓壁做圆周运动，贴着物料堆积的底部持续旋转。旋转的刮片直接切断、搅动物料底部，破坏物料颗粒之间相互支撑形成的拱形结构，同时也能刮掉黏在仓壁上的料，让物料在重力作用下重新下落。‌‌　　橡胶行业，物料：橡胶型粉体颗粒，刮料破拱阀尺寸DN250 PN10 材质304.刮料器旋转部件密封处应在立面，防止物料细颗粒进入。转动部分加装压缩空气风口，利用压缩空气防止细料进入。2.2KW防爆电机，品牌皖南/南阳/江苏大中等。减速机为一线品牌，破拱阀输出转速为3-4r/min，输出扭矩不小于2390Nm。　　Rubber 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.
