For the safety of spiral blades, the design of spiral blades should be more scientific. In addition, practicality is also an issue that must be considered in the design of spiral blades.
From a scientific point of view, the design of spiral blades should be set according to the standards of circular motion. The force arm of each rotor of the spiral blade should be set to an appropriate size to ensure the stability and safety of the spiral blade in use. In addition, when setting up the spiral blades, try to avoid the upper edge exceeding the horizontal standard, the lower edge not being lower than the keel line, and the trailing edge not exceeding the contour line of the groove. This position design allows the spiral blades to operate stably and efficiently.
From a practical point of view, whether the spiral blades are easy to disassemble should be considered in the design. Convenient disassembly can reduce disassembly time and facilitate transportation. In addition, the number of spiral blades must consider the actual performance. The number of spiral blades can achieve the best operating effect, which is also an important factor for us to consider.
Whether scientific or practical, the above principles cannot be ignored in the design of spiral blades. On the contrary, the above issues should not be ignored but taken seriously.
1. When designing spiral blades, the manufacturer’s appearance of the equipment is smooth and neat. Not only that, its accuracy and resistance have also been improved, improving the practical performance of the spiral blades.
2. Since the spiral blades are formed using cold rolling technology, they have better hardness and wear resistance.
3. Another advantage of spiral blades is that there is no welding during the production process.
Most spiral blades are stamped from thin steel plates with a thickness of 4-8 mm, and then welded to the rotating shaft blades and to each other. For transporting ash with high wear and viscosity, the spiral surface is rolled with flat steel or cast with cast iron. The spiral blades are generally made into scales, that is, the generatrix of the spiral surface is a straight line perpendicular to the spiral axis.
Boiler slagging generally uses full-blade steel plates. Introduction to the main components of the fuselage: As long as the inclined shaftless screw conveyor operates with the help of the driving device, the cinders will enter the chute through the ash hopper. The rolling of the spiral shaft drives the spiral blades, causing the cinders to rise along the inclined axis and reach the cinder outlet above the chute for discharge.
