蜗杆重载破拱器(料仓刮料破拱器)常用于粉末、颗粒类物料的料仓，解决起拱、架桥、黏壁导致的堵塞和不下料问题。蜗杆重载破拱器由电机带动蜗杆旋转，蜗杆与蜗轮啮合，通过蜗轮蜗杆的传动放大扭矩，再由蜗轮带动内圈，内圈带动刮板在料仓内做圆周旋转运动，通过机械刮削和推力破坏物料结拱结构，让物料恢复流动‌，从而实现破拱。常见尺寸DN100~DN1000.其他尺寸均可定制生产，如小型的DN50.或大型DN1200.DN1300均可非标定制。常见材质钛材、304、310、316、碳钢、内衬陶瓷/聚氨酯、喷涂碳化钨、陶瓷等。       　　蜗杆重载破拱器结构组成：　　驱动电机‌：提供旋转动力。电机、减速机选择：皖南、卧龙、国茂、西门子、ABB、SEW、Flender、NORD、住友，或客户指定品牌，防爆电机可选。　　‌传动机构‌：把电机动力传递给刮板，常见的是齿轮传动或涡杆传动。涡杆传动方式的扭矩更大、能耗相对更低。　　‌刮板‌：直接接触物料的核心部件，绕仓壁旋转完成破拱动作。‌‌F型刮板样式，一字型/直板型，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。　　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。　　料仓堵料架桥常见原因：　　1、粉体物料空隙率过高‌：粉体因空气滞留，经挤压后产生黏性结块，形成天然拱桥。　　2、颗粒形状不规则或粒径不均‌：大块物料与细粉混合时容易相互卡位搭桥;粉碎料大小不一、棱角尖锐，流动性远差于全新颗粒料。　　3、含水率高、易吸潮结块‌：水分超过5%时流动性明显下降，湿度每增加2%，下料效率可能下降30%。雨季或空气湿度大时尤其明显，物料表面发粘、抱团结块，在仓内形成拱桥。　　4、高黏附性物料‌：如黏土、湿煤等容易黏附仓壁形成结拱，长期堆积后越压越实。　　料仓刮料破拱器尺寸：DN50~DN1000或非标定制。　　刮料破拱器材质：钛材，整机不锈钢系列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。　　部分客户需求：　　锂电负极材料用蜗杆破拱器，尺寸DN200.防止物料搭桥，工频电机防护等级IP55(1.1kW,2.3A，约10RPM)SUS304.内表面和搅拌桨叶镜面抛光至Ra≤0.3m，外表面亚光处理。电机防护等级IP55:安徽皖南品牌，新国标二级能效IE4.减速机:为国贸品牌。　　物料：化工行业催化剂。DN350  转速5.1r/min，绝缘等级F，B级温升，防护等级IP65.防爆：隔爆 EXdⅡCT4.电机采用南阳防爆、ABB或佳木斯。　　物料：重质碳酸钙粉体，会出现架桥现象，需求破拱，连接法兰式DN300.物料接触部分不锈钢304.西门子变频电机，国茂减速机。　　物料：磷酸一铵，刮料破拱器规格型号： DN350 PN10;传动方式：直连式，整阀采用二代全齿轮传动结构，材质要求：304不锈钢 + 接触面4K镜面处理;物料接触部位精抛光;刮板F型;密封形式： 气密封;电机3kw SEW;减速机国茂。　　破拱器+星型卸料阀，化工粉料仓用，蜗杆重型刮料破拱器，DN500.

The worm heavy-duty arch breaker is driven by a motor to rotate the worm, which meshes with the worm gear. The torque is amplified through the transmission of the worm gear, and then the inner ring is driven by the worm gear. The inner ring drives the scraper to rotate in a circular motion inside the silo. Through mechanical scraping and thrust, the arch structure of the material is destroyed, allowing the material to resume flow and achieve arch breaking. Common sizes range from DN100 to DN1000. and other sizes can be customized for production, such as small sizes like DN50. or large sizes like DN1200 and DN1300. which can be customized non-standard. Common materials include titanium, 304. 310. 316. carbon steel, ceramic/polyurethane lining, sprayed tungsten carbide, ceramics, etc.　　Structure composition of worm heavy-duty arch breaker:　　Drive motor: Provides rotational power. Motor and reducer selection: Wannan, Wolong, Guomao, Siemens ABB、SEW、Flender、NORD、 Sumitomo, or customer specified brand, explosion-proof motor is optional.　　Transmission mechanism: It transmits the power of the motor to the scraper, commonly through gear transmission or vortex rod transmission. The vortex rod transmission method has greater torque and relatively lower energy consumption.　　Scraper: The core component that directly contacts the material and rotates around the warehouse wall to complete the arch breaking action. F-shaped scraper styles, including straight/straight plate, double scraper styles, and upper and lower scraper styles, can be customized according to the silo style or customer specified styles.　　Sealing method: Multiple sealing methods, including mechanical sealing and gas sealing, are used to prevent materials from entering the transmission device.　　Common reasons for material blockage and bridging in silos:　　1. High porosity of powder materials: Due to air retention, the powder forms sticky lumps after compression, forming a natural arch bridge.　　2. Irregular particle shape or uneven particle size: When large pieces of material are mixed with fine powder, they are prone to jamming and bridging each other; The crushed materials vary in size, have sharp edges, and have much poorer flowability than brand new granular materials.　　3. High moisture content, prone to moisture absorption and agglomeration: When the moisture content exceeds 5%, the flowability significantly decreases, and for every 2% increase in humidity, the cutting efficiency may decrease by 30%. Especially during the rainy season or when the air humidity is high, the material surface becomes sticky, clumped, and forms an arch bridge inside the warehouse.　　4. Highly adhesive materials, such as clay and wet coal, are prone to sticking to the warehouse walls and forming arches. After long-term accumulation, they become denser and more compacted.　　Size of silo scraper arch breaker: DN50~DN1000 or customized non-standard.　　Scraper and arch breaker material: titanium material, stainless steel series 304.316L, 2205904 for the whole machine.
