无轴螺旋输送机是一种采用无中心轴设计的物料输送设备，通过整体钢制螺旋体推送物料，具有抗缠绕性强、环保性能好等特点。以下是其主要特点和应用：
一、核心特点
.抗缠绕性
无中心轴设计避免带状、粘稠物料（如栅渣、污泥、垃圾）的缠绕问题，特别适合污水处理和垃圾处理行业。
.高效输送
输送量可达同规格有轴设备的1.5倍，单机最大输送长度60米，支持多级串联超长距离输送。
.环保密封
全封闭结构防止物料泄漏，螺旋表面易清洗，符合卫生要求。
.低能耗高扭矩
.扭矩可达4000N/m，低速运行平稳，能耗较低。
二、结构组成
驱动装置：多采用摆线针轮减速机或硬齿面齿轮减速机，通常安装在出料端。
螺旋体：不锈钢或碳钢材质，无轴设计。
机壳：U型或O型，可选不锈钢、碳钢或玻璃钢材质。
衬板：耐磨塑料、橡胶或铸石板，减少摩擦。
三、应用场景
污水处理：输送栅渣、压滤机泥饼。
化工/造纸：处理粘稠、易缠绕物料。
垃圾处理：运输生活垃圾等。
The shaftless screw conveyor is a material conveying equipment designed without a central shaft, which pushes materials through an integral steel spiral body and has the characteristics of strong anti winding and good environmental performance. The following are its main features and applications:
1、 Core Features
Resistance to entanglement
The design without a central axis avoids the entanglement problem of strip-shaped and viscous materials such as slag, sludge, and garbage, making it particularly suitable for the sewage and garbage treatment industries.
Efficient transportation
The conveying capacity can reach 1.5 times that of equipment with shafts of the same specifications, and the maximum conveying length of a single machine is 60 meters. It supports multi-stage series ultra long distance conveying.
Environmentally friendly sealing
The fully enclosed structure prevents material leakage, and the spiral surface is easy to clean, meeting hygiene requirements.
Low energy consumption and high torque
The torque can reach 4000N/m, running smoothly at low speeds with low energy consumption.
2、 Structural composition
Drive device: Cycloid pinwheel reducers or hard toothed gear reducers are commonly used, usually installed at the discharge end.
Spiral body: made of stainless steel or carbon steel, with no shaft design.
Chassis: U-shaped or O-shaped, available in stainless steel, carbon steel, or fiberglass materials.
Lining plate: Made of wear-resistant plastic, rubber, or cast stone to reduce friction.
3、 Application scenarios
Wastewater treatment: conveying grid slag, filter press mud cake.
Chemical/papermaking: Processing viscous and easily tangled materials.
Waste disposal: transportation of household waste, etc.
