Two-way screw conveying device

Abstract

The invention relates to a two-way screw conveying device which comprises a speed reducing motor (1), a driving component (2), a discharge hole (3), a screw shaft (4), feeding holes (5), a hanger bearing (7), a housing case (9) and a driven component (10), and is characterized in that one section of the screw shaft (4) is provided with a positive spiral vane (60), and the other section of the screw shaft (4) is provided with a negative spiral vane (61); the two feeding holes (5) are respectively positioned at the tail ends of the two sides of the positive spiral vane (60) and the negative spiral vane (61); and the discharge hole (3) is positioned between the positive spiral vane (60) and the negative spiral vane (61). The screw shaft is welded with the two sections of vanes with the opposite screw directions, so that lead powder arranged at the two ends of the screw shaft can be conveyed into a middle powder outlet and then is output when the screw shaft is driven to rotate by the motor. The two-way screw conveying device has the advantages that the screw length is reduced, the material is saved, and the cost is reduced; meanwhile, as the screw length is reduced, the screw operation is more reliable.

Description

technical field [0001] The invention relates to a lead powder conveying device, in particular to a two-way screw conveying device which realizes two-way conveying of lead powder. The device is mainly used for centralized powder discharge of multiple powder collectors or multiple powder bins. Background technique [0002] Currently, figure 1 The above is a structural schematic diagram of a screw conveyor commonly used in the market for lead powder transportation. It is mainly composed of a geared motor 1, a driving component 2, a discharge port 3, a screw shaft 4, a feed port 5, a spiral blade 6, a suspension bearing 7, a cover plate 8, a casing 9 and a driven component 10. It passes through The motor drives the screw shaft 4 to rotate, and the rigid helical blade 6 on the rotating shaft 4 pushes the lead powder to carry out the delivery of the lead powder, but it can only realize the one-way delivery of the lead powder. figure 2 It is the installation form of the screw co...
