Usage and Introduction:
This device is suitable for continuously and uniformly conveying loose, viscous, and easily entangled materials, with a conveying temperature of up to 100 degrees and a large inclination angle of less than 45 degrees. Widely used in industries such as building materials, chemical engineering, environmental protection, power, hospitals, chemical engineering, metallurgy, etc., sludge is also suitable for transporting materials such as sediment, grid slag, and sludge cake produced after sludge dewatering in sewage treatment plants. This product mainly consists of a driving device, a conveyor screw, a U-shaped groove, a lining plate, a cover plate, a feeding port, a discharging port, a machine cover, a base, etc.
Spiral material: carbon steel or stainless steel, depending on the usage conditions and the properties of the conveyed material.
U-shaped groove material: carbon steel plate or stainless steel plate, depending on the usage conditions and the properties of the conveyed material.
Lining material: rubber, polyethylene, polytetrafluoroethylene nylon, wear-resistant steel plate, etc., depending on the usage conditions and the properties of the conveyed material.
Drive device: composed of a motor and a reducer, which can be placed at the inlet or outlet end. The reducer can be a cycloidal pinwheel reducer, worm gear reducer, or gear reducer as needed.
Discharge method: Vertical discharge, the length and width of the discharge outlet can be specified by the user; Axial discharge, with an open end.
Installation method: Horizontal or inclined, with a large inclination angle of 45 ° for the structure of the shaftless screw conveyor
The shaftless screw conveyor has a novel and reasonable structure, advanced technical indicators, good sealing performance, strong applicability, low overall noise, easy operation and maintenance, and flexible layout of inlet and outlet positions.

The design of the structure of the shaftless screw conveyor ensures the smooth flow of the processed materials without blockage; There is a drainage function during the work process. The shaftless screw conveyor is mainly composed of shaftless screw, U-shaped spiral groove, cover plate, lining plate, inlet and outlet ports, discharge port, and driving device. The material is input through the inlet port, pushed by the shaftless screw, and output through the outlet port. Drive device: The drive device is placed at one end of the screw conveyor and adopts a direct connection form between the motor reducer and the screw drive shaft, without the need for a coupling. It is easy to disassemble and maintain, and the drive shaft can withstand the load of bending moment and axial compression force acting simultaneously.
The structural driving device (motor and reducer) of the shaftless screw conveyor adopts the structural form of high-quality shaft mounted reducer produced by SEW company. It operates flexibly, smoothly and reliably, without abnormal noise, and all joint surfaces and input and output shaft seals of the reducer will not leak. The drive motor is suitable for 380V, 3-phase, 50Hz, with a protection level of IP55 (outdoor type) and an insulation level of F.
WLS shaftless screw conveyor U-shaped section: The appearance is basically the same as the LS series screw conveyor.
Shaftless screw conveyor: The screw body is a thick strip screw, shaftless screw, and the head is connected to the drive shaft. Structurally, there are two types of blades: single blade and double blade. In terms of material, there are two types: carbon steel and stainless steel. There are two types of pitch ratios: 1:1 and 2:3.
Structure of shaftless screw conveyor
Sliding lining plate: a working support component for the middle and tail of the shaftless spiral body, which is made of high-strength engineering plastics, stainless steel, and other high wear-resistant materials.
WLSY shaftless screw conveyor
Working components: Similar to the WLS type working components, it adopts the excellent and mature technology of LSY series screw conveyor and combines the structural characteristics of WLS type screw conveyor.
Circular tube casing: With good sealing performance, it can reach the airtightness level (0.02mpa) and can work under positive and negative pressure conditions.
The shaftless screw conveyor is easy to install, just use expansion bolts to fix the steel support on the concrete foundation. It can operate intermittently or continuously for 24 hours a day.
The shaftless screw conveyor is equipped with overload protection function in electrical design, which can meet the all-weather safe and effective operation of the shaftless screw conveyor.
scope of application

Shaftless screw conveyor
Ordinary models have unique advantages in conveying winding materials (such as household waste) and fiber materials (such as sawdust and wood chips).
Heat resistant models: conveying hot and high-temperature materials without tail support. Transportation of high-temperature recovered dust and high-temperature furnace ash (slag) in blast furnaces.
WLSY shaftless screw conveyor ordinary model: conveying highly adhesive, paste like viscous materials. Such as sludge in sewage, high moisture content slag, etc.
Explosion proof machine type: transportation of flammable and explosive materials. Such as the feed of fuel (coal powder) in the fuel chamber.
The spiral blades of the shaftless screw conveyor are made of stainless steel material and cast through a special mold, which has sufficient strength and rigidity. The blade surface is smooth and free of burrs, and has a suitable rotation speed, effectively ensuring that there will be no pollution entanglement or blockage during the transportation of slag. At the same time, the spiral blades will not deform even when the conveying volume is large. Widely used in building materials, power, chemical, metallurgical, coal, aluminum magnesium, machinery, light industry, grain and food industries.
