Abstract
The utility model relates to a powder feeder comprising a material barrel, wherein a transmission shaft is arranged in the material barrel, a plurality of conveying vanes are evenly distributed on the transmission shaft in the axial direction, the two ends of the transmission shaft are fixed in the material barrel through an upper bearing and a lower bearing respectively, and the upper bearing and the lower bearing are closely matched with the material barrel. A plurality of backward vanes are distributed in the distance, from the upper bearing to a material outlet, on the transmission shaft in the axial direction, the directions of spiral angles of the backward vanes are opposite to those of the conveying vanes, and the number of the backward vanes is smaller than that of the conveying vanes; and when the powder feeder works, the transmission shaft rotates, the vanes are driven to rotate, the rotating conveying vanes are matched with the backward vanes, and supplied material is right conveyed to the material outlet. Thus, volatilization and leakage of the supplied material are effectively prevented, meanwhile the problem that the outlet is choked is avoided, and a production process can be normally carried out.
Description
Technical field
The utility model relates to a kind of powder conveyer, specifically, is a kind of powder feeder.
Background technology
In industrial process, the conveying of powder is common technological process, and in the course of conveying of powder, ubiquity leaks and stops up two large problems, has influence on normal production process, also can waste material, causes environmental pollution.The utility model has increased blade with the conveying blade contrarotation at traditional feeder, and supplied materials is not stopped up; With the barrel both sides sealing, prevent from revealing.
The utility model content
The purpose of this utility model is to provide a kind of powder feeder, add the backward vane opposite with conveying blade helical angle direction in a kind of exit of powder feeder and install function admirable mechanical seal at the bearing place, efficiently solve and leak and blocking problem.
For achieving the above object, the utility model provides a kind of powder feeder, comprises barrel, barrel is built-in with transmission shaft, axial uniform several conveying blades on the transmission shaft, the transmission shaft two ends are fixed in the barrel by metal (upper respectively, and metal (upper and barrel form and closely cooperate; At head bearing to the distance of discharging opening, several backward vanes of axial distribution on the transmission shaft, the helical angle direction of backward vane is opposite with conveying blade, quantity is less than conveying blade; During work, transmission shaft rotates, and drives the blade rotation, and conveying blade and the backward vane of rotation cooperatively interact, and just in time supplied materials are delivered to discharging opening.The volatilization that has effectively prevented supplied materials is revealed, and has also avoided stopping up the problem of outlet simultaneously.
The beneficial effects of the utility model are: simple in structure, solved leakage and blocking problem, and accomplishing does not have waste, pollution-free, and the process of production is normally carried out.

Fig. 2 represents inner structure scheme drawing of the present utility model
Drawing reference numeral: 1-feeder hopper, 2-feeder, 3-discharge bucket, 4-feed bin, 21-barrel, 22-conveying blade, 23-lower bearing, 24-motor, 25-backward vane, 26-transmission shaft, 27-head bearing, 28-discharging opening, 29-inlet point.
The specific embodiment
To closing drawings and Examples the utility model is further described below.
Know referring to accompanying drawing 1 and accompanying drawing 2, the utility model proposes a kind of powder feeder, comprise barrel 21, barrel 21 is built-in with transmission shaft 26, axial uniform several conveying blades 22 on the described transmission shaft 26, transmission shaft 26 two ends are fixed in the barrel 21 by metal (upper respectively, and metal (upper and barrel 21 form and closely cooperate; To the distance of discharging opening 28, axially be equipped with a backward vane 25 at head bearing 27 on the transmission shaft 26, the helical angle direction of backward vane 25 is opposite with described conveying blade 22; Adopt motor 24 as engine installation, drive transmission shaft 26 and rotate.Motor 24 is installed in lower bearing 23 places.Supplied materials in the feeder hopper 1, is concentrated to accumulate in the feed bin 4 by engine installation in feeder 2 is transported to the discharge bucket 3 of higher position.
During work, drive through motor 24, transmission shaft 26 rotates, and drives the blade rotation, and the conveying blade 22 of rotation is carried powder from inlet point 29 toward discharging opening 28 directions, and the backward vane 25 of rotation is pressed to discharging opening 28 to powder simultaneously, and then falls to discharge bucket 3.Both match, and make barrel 21 upper ends not occur stopping up.Because of head bearing 27 and all adaptive mechanical seal of lower bearing 23, no powder enters again, guarantees the normal operation of feeder 2.
