Abstract

The invention discloses a granule conveyor screw assembly, comprising a screw rod sleeved inside the hollow inner cavity of an external cylinder, and a discharging pipe installed at the lateral side at the top of the external cylinder; a feeding inlet arranged at the lateral side at the bottom of the external cylinder and a feeding pipe extending toward the exterior side of the feeding inlet installed at the lateral side at the bottom of the external cylinder; the screw rod comprises a shaft lever, and a thin rotary vane is wound at the lateral side of the shaft lever; and a thick rotary vane is wound, or a cylinder is sleeved at the periphery of the bottom of the shaft lever and a thick rotary vane is wound at the periphery of the bottom of the shaft lever. Because of the thick rotary vane structure at the bottom of the shaft lever and the combination of the thick and the thin rotary vanes, the materials are enabled to enter the interior of the external cylinder from the feed pipe; and because of the height of the thick rotary vane wound around the shaft lever is larger than that of the upper edge of the feed inlet, the materials will not contact the thin rotary vane at the initial stage of entering the cavity of the outer cylinder. The granule conveyor screw assembly can prevent the materials from filling up the thin rotary vane at the upper part of the screw rod to extrude and damage the equipment; and can finish operation at a slow-speed of rotation and large elevation angle working conditions of the screw rod.

Description

A kind of granule conveying screw rod assembly

Technical field

The present invention relates to helix transporting device, relate in particular to a kind of granule conveying screw rod assembly.

Background technology

The structure of the tube-type spiral conveyer in the existing known technology generally comprises an out cylinder that is fixed on the frame, and the screw shaft that is loaded on a band helicallobe at out cylinder center, and the screw shaft two ends are installed on the bearing seat, are rotated by driven by motor." a kind of tube-type spiral conveyer " (notification number is CN1884016A) as application number 200610051978.6 discloses a kind of tube-type spiral conveyer, comprise out cylinder, a motor that is fixed on the frame, out cylinder is provided with feed pipe and discharge nozzle, it also comprises the one-piece auger blade of a no spiral axis, helicallobe two ends central mounting is on bearing seat, and helicallobe is connected with motor by coupler.Be provided with anti-wearing liner between helicallobe and the out cylinder.This technical scheme is directly installed on center, helicallobe two ends on the bearing seat owing to adopt the one-piece auger blade of no spiral axis, makes the inner channel space that transmits material of out cylinder increase, thereby has increased the feed flow of material.The deficiency of this type of technical scheme is, helicallobe is located on the screw shaft, and its inner channel space that transmits material is a rigidity, in the process of course of conveying with drop or wide-angle conveying, because the action of gravity of material, material can be with helicallobe stranded and damage equipment.

Summary of the invention

Technical matters to be solved by this invention is the present situation at prior art, and a kind of granule conveying screw rod assembly that can realize that the material big-elevation is carried is provided.

The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of granule conveying screw rod assembly, comprise the screw rod that is sleeved in the out cylinder hollow cavity, and the out cylinder top-side is shaped on discharge nozzle; The out cylinder bottom sides has inlet point, and is shaped on the feed pipe that extends to the inlet point outside; Screw rod comprises axostylus axostyle, and wherein: the coiling of axostylus axostyle side is shaped on thin vane; The periphery coiling of axostylus axostyle bottom is shaped on thick vane, and perhaps the periphery of axostylus axostyle bottom is set with a cylinder, and the coiling of cylinder periphery is shaped on thick vane.

For optimizing technique scheme, the technical measures of taking also comprise: thick vane is axially upwards coiling extension from the axostylus axostyle bottom along axostylus axostyle; The length that thick vane coiling is extended is greater than the bore of inlet point.

The thickness of thick vane is greater than the thickness of thin vane; The vane spacing of thick vane is less than the vane spacing of thin vane; Thick vane compares more than or equal to 4 to 1 with the thickness of thin vane; The vane spacing is corresponding with the vane linea angulata.Little spacing can effectively limit the inlet amount of inlet point, makes the material can be not stranded at thin vane place.

The vane angle of thick vane is that 11 degree are to 16 degree.The vane angle of thin vane is more than or equal to 13 degree, and bottom-up the increasing progressively in vane angle of thin vane.Can progressively increase the gap in material space and increase axial thrust, thereby effectively offset the material deadweight.The out cylinder angle of elevation alpha is that 30 degree are to 45 degree.Screw speed is that per minute 20 goes to per minute 60 commentaries on classics.The thickness of thin vane blade is 3 millimeters to 10 millimeters.

The bottom-up ratio that increases progressively in vane angle of thin vane is 1.01 times to 1.2 times.Thick vane is in conjunction with thin vane, and cooperates the increasing progressively of vane angle angle of thin vane, can realize effectively that low speed, big-elevation carry.

First axle bed is run through at the axostylus axostyle top, and this top is shaped on the termination that can connect actuating unit; The out cylinder bottom is equipped with second axle bed; The out cylinder top is equipped with first axle bed.

Because the technical program has adopted the axostylus axostyle bottom that thick vane structure is arranged, thin vane and the combination of thick vane are provided with, make material enter out cylinder inside from feed pipe, be coiled in thick vane on the axostylus axostyle owing to highly be higher than the upper edge of inlet point, make material can not touch thin vane at the initial stage that enters the out cylinder cavity; And material is in the part of little vane spacing at the initial stage that enters the out cylinder cavity, in the process of elevation angle transmission, can avoid material to take thin vane space, screw rod top and extrusion damage equipment; And can under the operating mode of screw rod slow speed of revolution, big-elevation, finish the conveying operation smoothly.So that the present invention is a kind of novel structure, technology is simple, can realize the granule conveying screw rod assembly that material low speed, big-elevation are carried.
