Abstract

The utility model discloses a novel conveying device which has the metering function, comprising a spiral vane, a conveying shaft, a conveying shell and a frequency-changer motor, wherein two adjacent spiral conveying shaft vanes controlled by the same motor are meshed with each other; the middle of two adjacent spiral conveying shaft vanes controlled by different motors are spaced by a clapboard; the gap of the vane and the clapboard and the gap of the vane and the shell are 5 to 7mm; the thread intervals are increased along the conveying shaft direction in the range of the import flange, which means t1<t2<t3...<tn, thus being able to effectively stop the blocking of the conveying medium in each thread interval; the rear half part of the thread intervals are equal, and the outlet position is provided with a reversed vane, in order to avoid the blocking of the helix when the blanking is not smooth; and in addition, the spiral conveying device are separately controlled by two frequency-changer motors, and can quantitatively control each discharging quantity through controlling the frequency of the motor.

Description

A kind of feedway of novelty with function of measuring

Affiliated technical field

The utility model relates to a kind of metering and conveying device of powder material, relates in particular to the metering and conveying device of absorbent in the exhaust purification field.

Background technology

At present, single warehouse all is to adopt single-screw mode of movement to many equipment supply absorbents in the known exhaust purification technology, and when relating to two outlets, need connect a threeway above, cause regular plugging, and employing constant pitch, but the collected material of each blade of screw conveyor shaft increases gradually, whole like this helix transporting device unbalance stress in course of conveying, the material of collecting in the pitch at discharge end place is more, so discharge end can occur producing stuck phenomenon between conveying axis and the housing.In addition, at the other end of discharging opening, when blanking is not smooth, will ramming material, when conveying axis rotated, material can more be pressed more in fact, burns out motor to such an extent as to the result can block conveying axis.

Summary of the invention

For overcome problems such as plugging that existing metering and conveying device causes and discharge end be stuck in course of conveying, the utility model provides a kind of feedway with function of measuring of novelty, not only can avoid plugging and stuck phenomenon, and realize a plurality of discharge hole for discharge and quantitatively control load.

The technical scheme that its technical matters that solves the utility model adopts is: adopt a kind of ingear, measurable, multiple exit, variable pitch and have the device of anti-blade, comprise helicallobe, conveying axis, conveying housing, variable-frequency motor and dividing plate, two adjacent screw conveyor shaft blades of same electric machine control are meshing with each other, separate with dividing plate in the middle of the two adjacent screw conveyor shaft blades of different electric machine control, for avoiding occurring the dead angle, the gap of blade and dividing plate and blade and housing is 5-7mm; Helicallobe increases progressively along pitch on the conveying axis direction in the suction flange scope, be t1＜t2＜t3 ...＜tn so just can stop the stuck of the interior pumped (conveying) medium of each pitch effectively, and latter half pitch equates, and there is anti-blade in the exit, so as not to blanking when smooth spiral block.

In addition, this metering and conveying device can come respectively the quantitatively load of each outlet of control by controlling its frequency, again because its frequency range is bigger, so it can adapt to the output of material under the various operating modes respectively by two variable-frequency motor controls.

Of the present utility model have beneficial effect to be: avoid occurring plugging and stuck phenomenon in the course of conveying, and realize a plurality of discharge hole for discharge and quantitatively control load.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structural representation of the present utility model

Fig. 2 is the blanking construction drawing of single helicallobe

Fig. 3 is a side direction elevational schematic view of the present utility model

Among the figure, 1, helicallobe, 2, conveying axis, 3, carry housing, 4, bearing, 5. variable-frequency motor, 6. dividing plate.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

In Fig. 1, helicallobe (1), conveying axis (2), conveying housing (3), bearing (4) and variable-frequency motor (5) and dividing plate (6), helicallobe (1) welds to captive joint with conveying axis (2) and is integral, the combination of conveying axis (2) and helicallobe (1) is bearing in by two bearings (4) carries housing (3) to go up (need add middle bearing when fed distance is long), and the gap between the outward flange of helicallobe (1) and the conveying housing (3) is even.The two adjacent screw conveyor shaft blades (1) of realizing same electric machine control are meshing with each other, separate with dividing plate (6) in the middle of the two adjacent screw conveyor shaft blades (1) of different electric machine control, blade (1) is 5-7mm with the gap of dividing plate (6) and blade (1) and housing (3).Helicallobe (1) variable pitch ground in the suction flange scope extends along conveying axis (2), increases progressively along pitch on the conveying axis direction in the suction flange scope, i.e. t1＜t2＜t3 ...＜tn, its latter half is because of the identical employing constant pitch of material conveying.And, to stop up for preventing discharging opening, discharging flange place adopts anti-blade.In addition, this helix transporting device can come respectively the quantitatively load of each discharging opening of control by controlling its frequency respectively by two variable-frequency motor controls.

Claims
