System-level optimization analysis of screw conveyor

The screw loading conveyor is a continuous conveying machine without flexible traction components. It uses the rotation of the screw to generate relative movement between the material and the screw shaft to achieve the purpose of conveying, lifting and loading and unloading, and can be used in the conveying process according to needs. It completes mixing, compression, kneading and conveying of high-temperature materials. Therefore, screw conveyors are widely used and are one of the important mechanical equipment indispensable for modern production and logistics transportation.　　 screw conveyor has become one of the important mechanical equipment indispensable for the mechanization and automation of modern grain handling systems due to its particularity and professionalism. At present, the annual circulation of grain in my country is about 70 million tons. The main varieties of mobile are rice, wheat, corn and soybeans. Wheat is the main food crop second only to rice in the circulation of raw grain in my country, and its annual circulation is very large. Therefore, this article mainly focuses on the research on the horizontal screw loading conveyor for conveying wheat materials, which is of great significance to the modern grain handling system.

What types of spiral troughs does the screw conveyor have

What types of spiral troughs are there for screw conveyors? The troughs are generally U-shaped steel troughs with a length of 3000 or 3660mm. The spiral groove body has a top cover, and the top cover can be made into a dust-proof type when necessary. The U-shaped spiral trough of the angle steel flange is commonly used. The top flange is made of heavy-duty structural angle steel and welded flat with the upper edge of the spiral trough. The end face flange is welded by a profiling and is guaranteed to be aligned with the adjacent tank end face. The U-shaped spiral groove body of the flange flange is a groove body processed by a uniform piece of steel plate hemming. The groove body made in this way is light and strong. The end flange is welded with a mold to ensure that the adjacent groove body is welded. Faced with accuracy. The U-shaped spiral groove body of the double-folded flange is a groove body made of a unified steel plate through double-folding processing. This greatly increases the strength and rigidity of the tank. When it is connected with the flanged top cover and with proper gasket material, it can achieve effective dust-proof sealing. The channel steel U-shaped spiral trough is suitable for the occasions where the support distance of the screw conveyor is required to be long. The upper side of the trough is made of structural channel steel, which can be linked with the lower semicircular section trough with bolts or spring clips. U-shaped spiral trough with flow bottom: This type of spiral trough is suitable for occasions that require quick and easy access to the inside of the loading conveyor. The U-shaped spiral trough of the flow bottom is composed of a rigid upper channel steel and a lower semicircular section trough upper body. One side of the semicircular section trough is a hinged surface, and the other side is clamped by a spring clip or other forms of energy. Quick opening connection device.
