2012-03-28 07:56:48 The structural characteristics and performance of the shaftless screw loading conveyor
is a kind of equipment that transports materials without a central shaft and rotates by a spiral body. The conveying direction is determined by the spiral direction of the spiral blades. It can be conveyed in both directions. There is a wear-resistant nylon protective bushing. Can be sealed to prevent environmental pollution. The material can be discharged from the bottom and at the end. The special liner can work under high temperature. Compact structure, space saving, beautiful appearance, easy to operate, economical and durable. The grid slag material is transported to the designated position through the shaftless spiral body. It is composed of driving device, bracket, conveying screw, U-shaped groove, lining plate, cover plate, feeding port, etc. Shaftless screw conveyor has large thickness and long service life. The shaftless screw technology is adopted and the contact surface with materials is small. Low friction, no blockage and entanglement. The support adopts an integrally pressed U-shaped groove. The structure has high strength. It has a detachable upper cover for easy observation of the material conveying situation. The U-shaped groove and the shaftless spiral adopt a fast detachable resistance The grinding liner has a long service life and is easy to maintain and operate. The driving department adopts cycloidal pinwheel reducer, which has low noise, stable transmission and long life. The equipment has no end-hazard operation time of no less than two years; the life of the whole machine is no less than 10 years; the equipment is inspected once a year, the service life of electrical components is no less than 2 years, the reducer bearing is no less than 10 years, and the protective coating is no less than 3 years. The carbon steel parts are improved by sandblasting, and the rust removal reaches the Sa2.5 level. It is coated with zinc-rich primer, mica iron oxide intermediate paint, epoxy topcoat, and the total thickness of the paint film is not less than 250μm. Before packaging, the machined surface shall be treated with anti-corrosion according to GB4879 standard requirements. If the coating is damaged during transportation and installation, it should be repaired strictly according to the coating process. The quality level is not lower than that of the original coating. It can transport materials that cannot or are difficult to transport by traditional shaft screw machines and belt conveyors. Such as granular and powdery materials, wet and pasty materials, semi-fluid and viscous materials, materials that are easy to surround and entangle and easy to block. Because of the design of no central shaft, the sharp tool has a certain flexible integral steel screw to push materials, and the environmental performance is good.
