Do you know what types of screw conveyors are?

Screw conveyor is a commonly used transportation machine in various factories and mixing stations. It can only be responsible for conveying materials on the production line or after production and transporting finished products. Because of the wide range of applications, screw conveyors have many classifications. The screw conveyor produced by the manufacturer can be divided into several types. 1. Single screw conveyor

The most widely used conveyors are often seen in the mining, feed, grain and construction industries. Among them, the highly evaluated and widely used screw conveyor is the single screw conveyor. The main feature of the equipment is single-sided rotation, and standard steel pipes are used for transportation. The cylindrical body can convey materials in a horizontal direction or at a certain inclination angle. The whole structure is strong in rigidity and is suitable for conveying small pieces of materials. Powder and granular materials can also be transported.

2. Double screw conveyor

Compared with the above-mentioned single screw conveyor, this double screw screw conveyor combines two blades. The main feature is the addition of a pre-watering section, which can mix materials. This means that it can be continuously stirred while being transported up and down. This type of double screw conveyor is used to convey materials that have poor flow properties, large objects in volume or size, and need to be stirred, and are generally used in food processing and construction processing.

Three, combined screw conveyor

As the name suggests, from the name of the combined screw conveyor, we know that this type of screw conveyor is spliced together, combining two screw conveyors. Generally, this kind of equipment has two inlets and outlets. During the entire production process, if one inlet starts to transmit, the outlet will be spliced with the second inlet. This method can be transported farther, and is more suitable for large-scale automated production enterprises.

In addition, it should be noted that the screw conveyor relies on the rotation of the screw blade to push various materials.

If the length of the screw conveyor is too long-for example, there are many large workshops in the factory, or the height is high, and large lifting and large transportation are required, then the main shaft of the screw conveyor will deform or sag due to the length or material factors. The phenomenon.

At this time, you often hear the sound of friction from the screw conveyor. This is because the screw blades are rubbing against the pipe body. Therefore, when the screw conveyor is too long, you must add a hanging bearing device in the middle of the screw shaft to avoid this. This kind of spiral blade shaft sags and even wears the pipe body. In this way, the hanging bearing device is also the main and important part of the screw conveyor. When selecting and designing the spiral conveying pipe, we must consider the characteristics of the material, and improve and replace the parts according to the actual situation to reduce the wear of the parts.
