Product introduction: Spiral conveyor is a new type of conveying equipment developed for special material conveying. It uses screws on the internal shaft to professionally horizontally or vertically tilt various powders, particles, and small pieces of materials. For other materials with high deterioration and adhesion, it is easy to block the inside of the machine, so it is not suitable for operation. It is particularly suitable for various grains, cement, sand, and small stones, etc. The temperature requirements are also very loose, and the temperature of materials can be applied at -20~80 ℃, which has strong economic benefits.
Working principle of screw conveyor
When the screw shaft rotates, due to the gravity of the material and the frictional force generated between the material and the groove wall, the material can only move forward along the groove bottom of the conveyor under the push of the blades. The situation is like a nut that cannot rotate moving in translation along a rotating screw. The movement of the material in the intermediate bearing relies on the thrust of the material moving forward from behind. Therefore, the transportation of the material in the conveyor is completely a sliding motion. In order to keep the screw shaft in a favorable tensile state, the driving device and the discharge port are generally placed at the same end of the conveyor, and the feeding port is placed as close to the tail end of the other end as possible. The rotating spiral blades push the material for transportation, and the force that prevents the material from rotating together with the blades of the spiral conveyor is the weight of the material itself and the frictional resistance of the spiral conveyor housing to the material. The surface type of the blades varies depending on the material being transported, including solid surface type, belt surface type, and blade surface type. The spiral shaft of the spiral conveyor has a thrust bearing at the end of the material movement direction to provide axial reaction force to the spiral with the material. When the length is long, an intermediate hanging bearing should be added.
Advantages of Spiral Conveyor
1. The outer shell is made of high-quality steel, and the central shaft is processed with wear-resistant and non deformable special steel, which provides extraordinary safety and stability during the transmission process of the whole machine. Compared with similar specifications of equipment, we use a safer, more stable, and wear-resistant central shaft, which increases the material transmission speed several times
2. By utilizing advanced wire cutting and other processing equipment, the precision and standardization of the equipment are ensured. The screws on the central axis are made of new wear-resistant materials, enhancing the equipment's wear resistance, pressure resistance, and other properties
3. By ensuring the overall performance of the equipment, upgrading, improving, and optimizing it as a whole, the entire machine becomes more convenient to operate and easier to maintain
4. Fully utilize the advantages of the equipment to significantly increase the transmission capacity compared to traditional devices
This machine is powered by an electric motor as a whole, which drives the internal screw shaft to rotate. The material enters the bottom of the machine through a professional feeding port, and is transported step by step through the rotating screw until it reaches the upper end of the machine. In the process of internal design, common problems such as internal blockage were taken into consideration.
