The screw blade of the shaftless screw conveyor is made of stainless steel through casting through a special mold, so it has sufficient strength and rigidity, the surface of the blade is smooth and burr-free, and it has a suitable rotation speed, which can effectively ensure the process of conveying screenings. There will be no dirt entanglement and blockage, and the screw blade will not be deformed under the condition of large conveying volume.
The shaftless screw conveyor is composed of a shaftless screw, a U-shaped spiral groove, a cover plate, a lining plate, an inlet/outlet, a discharge port and a driving device. Outlet output. The driving device is placed at one end of the screw conveyor, and adopts the direct connection form of the motor reducer and the screw drive shaft, without coupling, easy to disassemble and maintain, and the drive shaft can bear the load of bending distance and axial extrusion force at the same time. The drive motor is suitable for 380V, 3-phase, 50Hz, its protection class is IP55 (outdoor type), and its insulation class is F class. The wear-resistant lining in the U-shaped spiral conveying trough is set in a semicircle shape, and its arc is set to match the radius of the shaftless spiral body to reduce excessive clearance and improve the conveying effect; the wear-resistant lining is made of nylon material with high wear resistance, which is easy to install And replacement, long service life. The U-shaped spiral groove is made of stainless steel plate. Except for the opening of the feeding port, the rest is closed along the spiral groove with a flat cover. The entire transmission process is carried out in a sealed groove to reduce noise and odor discharge; There is a discharge port at the bottom of the U-shaped groove, and it is equipped with a drain ball valve.
The shaftless screw conveyor has no high-speed running parts, so that the wear of the transmission screw is low, the energy consumption of the equipment is low, and the noise is low. The shaftless screw conveyor is easy to install. It only needs to use expansion bolts to fix the steel support on the concrete foundation. It can run intermittently or continuously 24 hours a day. The shaftless screw conveyor is equipped with an overload protection function in the electrical design, which can meet the safe and effective operation of the shaftless screw conveyor around the clock. The electrical components for controlling the shaftless screw conveyor are included in the on-site electrical control box of the grille. For specific control requirements, see the electrical control part of the grille.
