Description
Technical field
The utility model relates to a kind of feed screw, particularly relates to a kind of for the feed screw of convey materials to the reducing of heating furnace.
Background technology
Feed screw is a kind of machinery for heating furnace or pyrolysis oven convey materials, when giving various different heating furnace feed, because heating in-furnace temperature is higher, usually, can reach a few Baidu, under conduction of heat, the temperature of feed screw and heating furnace link also can be very high, the huge temperature difference is formed thus between feed screw charging aperture and discharging opening, the temperature of material in feed screw of conveying is raised to a few Baidu from normal temperature, the material of discharge end starts to soften along with the rising of temperature, viscosity strengthens, this adds increased the resistance of motion of material, simultaneously, under the effect of inherent moisture, volume of material expands gradually, often there will be clogging, affect the operation of feed screw.
Utility model content
The technical problems to be solved in the utility model is to provide that a kind of structure is simple, mass transport is unobstructed, can ensure the reducing stove charger that charger normally runs.
The utility model reducing stove charger, comprise feeding cylinder, the helical axis be arranged in feeding cylinder, the helical blade be fastened outside helical axis, one end of described feeding cylinder arranges charging aperture, the other end arranges discharging opening, described feeding cylinder comprise connect as one successively feed zone, transportation section and discharging section, described charging aperture is arranged on feed zone, and described discharging opening is arranged on discharging section, and the diameter of the helical blade of described feed zone is less than the diameter of the helical blade of transportation section and discharging section.
The utility model reducing stove charger, the diameter of the helical blade of wherein said feed zone
wherein D is specified blade diameter, i.e. transportation section helical blade diameter, and d is feeding cylinder inside spin shaft diameter, and K is the pyrolysis material coefficient of expansion.
The utility model reducing stove charger, adopts static and dynamic sealing between wherein said helical axis and helical blade.
The utility model reducing stove charger, wherein said discharging opening stretches in pyrolysis oven.
The utility model reducing stove charger difference from prior art is that the utility model reducing stove charger comprises feeding cylinder, helical axis, a few part of helical blade, structure is simple, feeding cylinder comprises feed zone, transportation section and discharging section, the diameter of the helical blade of feed zone is less than the diameter of the helical blade of transportation section and discharging section, adopt variable-diameter structure, can suitably reduce feed quantity, when making material advance to discharging opening and the high temperature location of charger, still maintain certain gap with feed cylinder inwall, also can not block even if expand, can guarantee that mass transport is unobstructed, ensure that charger normally runs.
Below in conjunction with accompanying drawing, reducing stove charger of the present utility model is described further.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model reducing stove charger.
Detailed description of the invention
As shown in Figure 1, the utility model reducing stove charger comprises feeding cylinder 1, the helical axis 2 be arranged in feeding cylinder 1, the helical blade 3 be fastened outside helical axis 2, one end of feeding cylinder 1 arranges charging aperture 11, the other end arranges discharging opening 12, feeding cylinder 1 comprise connect as one successively feed zone, transportation section and discharging section, charging aperture 11 is arranged on feed zone, and discharging opening 12 is arranged on discharging section, and discharging opening 12 stretches in pyrolysis oven 4 '.
The diameter Dj of the helical blade of feed zone is less than the diameter D of the helical blade of transportation section and discharging section.
The diameter D of the helical blade of feed zone
jby formula
calculate, wherein D is specified blade diameter, i.e. transportation section helical blade diameter, and d is feeding cylinder inside spin shaft diameter, and K is the pyrolysis material coefficient of expansion.
Static and dynamic sealing is adopted between helical axis and helical blade.
The amount adjustable of charger convey materials, can realize the continuous setup to conveying capacity by adjustment charger feeding electric motors frequency.
Above-described embodiment is only be described preferred embodiment of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
