WLS type shaftless screw conveyor

The WLS type shaftless screw conveyor adopts a shaftless design and uses a flexible integral steel screw to push materials. It mainly consists of a power unit, head assembly, casing, shaftless screw body, lining plate, feeding port, discharging port, machine cover (when needed), base, etc.

Structure of WLS type shaftless screw conveyor:

1、 WLS shaftless screw conveyor inlet and outlet: There are two types: square and circular. If the user has no requirements, the square type will be supplied.

2、 WLS shaftless screw conveyor shaftless screw body: made of stainless steel or steel.

3、 The head of the WLS shaftless screw conveyor is equipped with thrust bearings, which can withstand the axial force generated when conveying materials.

4、 WLS shaftless screw conveyor housing: The housing is U-shaped, with an upper cover (if needed), made of stainless steel, carbon steel, or fiberglass.

5、 WLS shaftless screw conveyor liner: made of non-metallic material.

6、 WLS shaftless screw conveyor drive device: using cycloidal pinwheel reducer or shaft mounted hard tooth surface gear reducer, the drive device should be designed to be located at the discharge port end as much as possible, so that the screw body is in a tensile state during operation.

Characteristics of WLS shaftless screw conveyor:

1、 WLS shaftless screw conveyor has strong anti winding performance: due to the absence of shaft interference, it has excellent performance in conveying belt shaped, viscous materials, and easily entangled materials. For example, it is used for conveying fine grids in sewage treatment plants, with a net distance of 50mm between the grid bars for cleaning machine slag and filter press mud cake, or for handling and transporting garbage in garbage treatment sites, which can prevent accidents caused by blockage.

2、 WLS shaftless screw conveyor is environmentally friendly and powerful. The shaftless screw conveyor adopts fully enclosed conveying and easy to clean spiral surface, which ensures environmental hygiene and prevents contamination and leakage of the conveyed materials.

3、 WLS shaftless screw conveyor has high torque and low energy consumption. Due to the fact that the spiral has no shaft, the material is not easily blocked, and the discharge port is not blocked, so it can operate at a lower speed, transmit smoothly, and reduce energy consumption. The torque can reach 4000N/m.

4、 WLS shaftless screw conveyor has a large conveying capacity. The conveying capacity of the shaftless screw conveyor is 1.5 times that of the traditional shaft screw conveyor with the same diameter.

5、 WLS shaftless screw conveyor has a long conveying distance. The single machine conveying length can reach 60 meters. And according to user needs, multi-level series installation can be adopted to transport materials at a distance.

6、 The WLS shaftless screw conveyor is capable of mobile operation. Using lining plates, the machine can operate at high temperatures. Compact structure, space saving, beautiful appearance, easy operation, and economy.

The WLS type shaftless screw conveyor uses a rotating steel screw to transport materials, which can convey dry, wet, viscous, powdery, and rough materials.

The structural characteristics of WLS type shaftless screw conveyor:

U-shaped section: The external structural dimensions are basically the same as those of the LS series screw conveyor.

Axial free spiral: The spiral body is a thick strip spiral, with no axial rotation axis, 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. According to the pitch ratio, there are two types: 1:1 and 2:3.

Sliding lining plate: a working support component for the middle and tail of the shaftless spiral body, divided into three types of materials: engineering plastic, stainless steel, and other high materials.

Working parts: basically the same as WLS type working parts. Absorbing the mature technology of LSY series screw conveyor and incorporating the structural characteristics of WLS type screw conveyor.

Round tube casing: It is tightly sealed and can achieve the performance of an airtight machine (0.02mpa), and can work under positive and negative pressure conditions.
