1, Summarize
Without shaft screw conveyor is mainly used for the environmental protection, the papermaking industry, chemical industry, food, medicine, beverage industries stand with strong sex conveying materials, paste sticky materials (such as chemical raw materials and waste paper pulp, malt, sludge, etc) and prone to tangling materials (such as living garbage), has a unique advantage. So without shaft screw conveyor and says the winding conveyor belt conveyor, garbage disposal.
2, Working principle
Without shaft screw conveyor in conveying principle and general screw conveyor basic same: that is like a root of rotating shaft, drive a screw nuts along the axial movement, as without shaft screw conveyor helicoid equivalent to screw axis, material is equivalent to screw conveyor nut, when helicoid continuous rotation is material also continuous transmission. Without shaft screw conveyor helicoid thick leaves for shingles, through without shaft screw conveyor driver drive, the middle without shaft, helicoid and cabinet wall bottom liner contact (sliding).
3, Characteristics
Resistance to coil sex strong: because there is no central shaft for conveying belt, interference, sticky materials, and prone to tangling material is special advantages, such as used in conveying sewage treatment plant, the fine grille article from 50 mm net bars the decontamination machine gate slag and pressure filter materials, such as mud cake, or garbage disposal sites processing transportation, can prevent obstruction garbage caused by accidents.
Environmental protection performance is good: without shaft screw conveyor adopt totally closed conveying and cleaning surface, can guarantee the spiral environmental health and sent by contaminated material does not, and not leak.
Torque is big, low energy consumption: because without shaft, material not easily spiral jams, discharging excuses not to jam, and therefore can be lower running speed, smooth transmission, reduce the energy consumption. Torque is 4000 N/m can be.
Large transportation amount is same diameter, the traditions of shaft screw conveyor 1.5 times.
Long distance transportation of single: transportation length 60 meters. And based on user needs, use multilevel tandem installation, long distance transmission materials.
Compact structure, save a space and beautiful outlook, simple operation, economy and durability.
