First, double shaftless screw conveyor structure features: WLS shaftless screw conveyor double U-shaped cross-section: Shape and LS series screw conveyor is basically the same. Double shaftless screw conveyer belt-like spiral body is thicker, shaftless screw head associated with the drive shaft. Structurally divided into single, double blade two, carbon steel on steel, stainless steel categories, Ann pitch ratio of 1: 1 and 2: 3 aspect. Slip lining: intermediate shaftless screw body and tail work supports, from high strength engineering plastics material, stainless steel, high wear-resistant materials other categories. WLSY double shaftless screw conveyor working parts: parts and WLS-type work essentially the same absorption using LSY series screw conveyor outstanding mature technology, both the structural features of WLS-type screw conveyor. Tube Chassis: good airtight performance, up dense gas (0.02mpa) performance, it can work in a positive, negative working conditions. Second, the scope double shaftless screw conveyor: WLS shaftless screw conveyor regular models: for wrapping materials (such as solid waste), fibrous materials (such as wood chips, wood chips) transport, has a unique advantage. Heat models: no tail end support when hot material, high temperature material transport. Such as blast furnace dust recycling high temperature, high temperature ash (slag) delivery. WLSY double shaftless screw conveyor regular models: transportation adhesion strong, pasty viscous material. Such as sewage sludge, muck and other high moisture content. Explosion-proof models: flammable and explosive materials transport. The fuel chamber fuel (pulverized coal) feed. Double shaftless screw conveyor uses: shaftless screw driven mainly by means of the head assembly, chassis, shaftless screw body, tank liners, inlet, a gate, the door (if necessary). base and other components. Drive: use of cycloidal wheel or shaft-mounted reducer Hardened gear reducer, the design should as far as possible driving means is provided in the discharge port side to make the spirochetes in operation in a state of tension. Head assembly: thrust bearings can support axial forces generated during transportation of materials. Chassis: chassis U-shaped or O type, the upper plus weatherproof cover, are made of stainless steel or carbon steel or fiberglass. Shaftless screw body: made of stainless steel or carbon steel. Tank lining: made of wear-resistant plastic plate or rubber sheet or cast stone and so on. Jin, a gate: a square and round two, usually into and out of the discharge port in the form determined by the user.
