A kind of anti-bridge formation hopper being applicable to various fill material
Technical field
The present invention relates to a kind of hopper, especially relate to a kind of anti-bridge formation hopper being applicable to various fill material.
Background technology
In various PVC granulation factory formula, generally need in raw material, to add various filler to improve properties of product.After adding filler, because various filler mobility status is different, easily extrude because of powder in hopper blanking process, the reasons such as poor fluidity allow material occur arch formation at hopper two slopes place.The main hand wall of current solution arch formation adds agitating device in hopper, destroys arch formation, but newly add the cost that agitating device improves equipment by stirring material.
Summary of the invention
Technical problem to be solved by this invention overcomes defect that above-mentioned prior art exists and provides a kind of and prevent arch formation and be applicable to the anti-bridge formation hopper of various fill material.
For achieving the above object, the present invention adopts following technical scheme:
A kind of anti-bridge formation hopper being applicable to various fill material, comprise hopper cylindrical shell, feeding mouth, discharging opening, described one of them sidewall of hopper cylindrical shell is vertical wall, and the sidewall epimere of remainder is vertical, hypomere has inclined-plane, and the sidewall of remainder is overlooked as semicircle or part circle.Non-vertical sidewall is connected and composed successively by vertical section one, slope section, vertically section two, described sidewall is interconnected to form the cylindrical shell of hopper, described feeding mouth is positioned at the upper end of hopper cylindrical shell, described discharging opening is positioned at the lower end of hopper cylindrical shell, and described feeding mouth cross-sectional area is greater than the cross-sectional area of described discharging opening.
The present invention changes the symmetrical structure of hopper common in prior art into dissymmetrical structure, has slope to change slope, side into from both sides, and side is vertical structure.Powder cannot stressed formation bridge formation one end at vertical end when blanking, reaches the object preventing from building bridge.Major advantage of the present invention: change the symmetrical structure of common hopper into dissymmetrical structure, powder vertically holding and cannot stopping when blanking, effectively prevent powder and occur arch formation in blanking process.Do not need to add agitating device more simultaneously, reduce cost.

Detailed description of the invention
Describe the present invention below in conjunction with Figure of description.With reference to accompanying drawing, be described in detail the preferred embodiment of the present invention, wherein all identical Reference numerals represent identical parts.
A kind of anti-bridge formation hopper being applicable to various fill material, comprise hopper cylindrical shell, feeding mouth 1, discharging opening 3, described one of them sidewall of hopper cylindrical shell is vertical wall (4-1), the sidewall of remainder is connected and composed successively by vertical section one (4-2), slope section (2), vertically section two (4-3), described sidewall is interconnected to form the cylindrical shell of hopper, described feeding mouth 1 is positioned at the upper end of hopper cylindrical shell, described discharging opening 3 is positioned at the lower end of hopper cylindrical shell, and the cross-sectional area of described feeding mouth 1 is greater than the cross-sectional area of described discharging opening.
Further, described slope section 2 is greater than 90 degree with vertical section one 4-2, the vertically angle of section two 4-3.
Described slope section 2 is preferably 120-150 degree with vertical section one 4-2, the vertically angle of section two 4-3.
The longitudinal cross-section of described slope section 2 is straight line or transition arc.
The longitudinal cross-section of described slope section 2 is semi arch.
In use procedure, powder enters hopper by hopper top, move downward under gravity, because hopper has one side to be vertical, powder after extruding is built bridge because cannot put forth effort at two ends to be formed simultaneously, can, because Action of Gravity Field vertically cannot hold stop, so just can avoid occurring arch formation.
When being described in specific embodiment of the present invention, those skilled in the art will recognize that the present invention can revise in the spirit and scope not exceeding claims.
