Double Drive Shaftless Screw Conveyor

Introduction of Double Drive Shaftless Screw Conveyor

Double drive shaftless screw conveyor refers to a shaftless screw conveyor with two shaftless shafts respectively. It is mainly used for conveying powdery and granular materials with strong viscosity and strong winding properties. Compared with single shafts, it has the advantages of mixing, Stirring effect, the rotation of the two screw shafts is opposite, which can prevent the material from jamming, and the conveying capacity is 1.5-2 times that of the single shaft. According to the different materials, carbon steel and stainless steel can be used.

Types of Double Drive Shaftless Screw Conveyor

1. According to the nature of the conveyed material, it is divided into:

Ordinary model: It has advantages for conveying winding (such as domestic waste) and fibrous materials (such as wood chips and wood chips).

Heat-resistant model: conveying materials and high-temperature materials without end support, such as a conveyor for high-temperature recovery of blast furnace dust and high-temperature furnace ash (slag).

Second, according to the equipment material is divided into:

Carbon Steel Shaftless Double Screw Conveyor: Made of Q235 carbon steel, it is mainly used in industries such as cement, coal, stone, etc., where there is a lot of wear and no special requirements for materials.

Stainless steel shaftless double screw conveyor: made of 304/3316L stainless steel, the welding process is fully welded without gaps, and all polished smooth without burrs, double welding inside and outside the inlet and outlet, acid and alkali corrosion resistance, high temperature resistance of 200 ℃, It is not easy to rust, which can prevent the material from being polluted during the conveying process, and there is no leakage phenomenon. It is suitable for industries such as food, medicine, and chemical industry that require hygiene.

Application of Double Drive Shaftless Screw Conveyor

Double drive shaftless screw conveyor is mainly used for a wide range of conveying equipment in the treatment of sewage and sludge. Sand and other materials are widely used in chemical, food, medicine, paper, beverage, environmental protection and other industries to transport materials with strong adhesion, paste-like viscous materials (such as chemical raw materials, waste paper pulp, malt, sludge, etc.) Winding materials (such as domestic waste) have unique advantages.

Working Principle of Double Drive Shaftless Screw Conveyor

Double drive shaftless screw conveyor is equipped with a solid screw in two seamless steel pipes, one of which is left-handed and the other is right-handed. When working, the two screws rotate through a pair of gears at the shaft extension position. Due to the rotation of the screw body, the material moves axially, so as to achieve the purpose of conveying.

Benefits of Double Drive Shaftless Screw Conveyor

1. The two spiral blades have opposite directions of rotation, one is left-handed and the other is right-handed, which can prevent the material from sticking to the spiral body, and is suitable for materials with large volume, poor fluidity, or materials that need to be stirred.

2. There are 2 screw shafts in one shell, which also have the functions of mixing, stirring and crushing while conveying the materials in the process.

3. Double shaftless design can prevent viscous materials from being blocked during the conveying process and discharge more smoothly.

4. The conveying capacity is 1.5-2 times that of the single shaft, and the conveying distance can reach 20 meters.
