One end of powder delivering pipe is connected near the side of lower section with batcher housing, and powder delivering pipe is connected with the inner chamber of batcher housing
Logical, the top of powder delivering pipe begins with an air-blowing mouth, and the other end of powder delivering pipe forms powder carry mouth, batcher housing
Side wall on be respectively equipped with high charge level meter and low level-sensing device, high charge level meter is arranged above batcher housing, and low level-sensing device is leaned on
Arrange below nearly batcher housing, at the top of batcher housing, offer powder input port, the sidepiece of powder input port is also opened up
There is a pneumostome.
Utility model discloses a kind of positive displacement screw rod metering batcher, and the advantage of the charging gear is：（1）Structure sets
Meter is reasonable, using reverse-flighted screw structure, the blocking obstructing problem that effectively solving powder occurs in screw rod progradation；（2）If
Height level-sensing device is put, and undue accumulation is avoided while powder storage capacity is ensured；（3）During powder carry, attached in delivery port
Nearly setting air-blowing mouth, it is to avoid the blockage problem of powder moisture absorption appearance occur；（4）Pneumostome is set above powder, is maintained in warehouse
Subnormal ambient.

Specific embodiment
With reference to the accompanying drawings, this utility model is further described below；
The utility model discloses a kind of positive displacement screw rod measures batcher, it includes batcher housing 1, and which is different from existing
There is technology to be：1 inner chamber of batcher housing is in hollow form, and in batcher housing 1, level is provided with a reverse-flighted screw 2, should
One end of reverse-flighted screw 2 is connected with the outfan of motor 3, and batcher housing 1 is provided with a powder carry near the side of lower section
Pipe 4, one end of the powder delivering pipe 4 are connected near the side of lower section with batcher housing 1, powder delivering pipe 4 and feed casing
The inner space of body 1, the top of powder delivering pipe 4 begin with an air-blowing mouth 5, and the other end formation powder of powder delivering pipe 4 is defeated
Mouth 6 is sent, high charge level meter 7 and low level-sensing device 8 on the side wall of batcher housing 1, is respectively equipped with, high charge level meter 7 is near batcher housing
Arrange above in the of 1, low level-sensing device 8 is arranged below batcher housing 1, and the top of batcher housing 1 offers powder input port
9, the sidepiece of powder input port 9 is further opened with a pneumostome 10.
In the specific implementation, powder is put into by the powder input port above batcher housing, while arrange pneumostome maintaining
Negative pressure.In powder storage feed cabin, and basic storage capacity is controlled by low level-sensing device.Arrange high charge level meter simultaneously to avoid storing
Powder pile up caused by excessive compression.Frequency conversion motor controls screw speed, it is ensured that quantitatively convey powder, and reverse acting spiral can then have
Effect avoids the extruding blocking during powder carry on screw rod.Finally, air-blowing mouth is set near delivery port, powder can be reduced and existed
Moisture absorption blocking in pipeline, the range of flow of batcher is 0.01 ~ 16 m3/h.
In the specific implementation, on the screw rod outer wall of the reverse-flighted screw 2, spiral distribution has positive external screw thread 11 and reversely
The hand of spiral of external screw thread 12, positive external screw thread 11 and reverse external screw thread 12 is contrary.
In the specific implementation, the diameter of thread of the diameter of thread of the reverse external screw thread 12 more than positive external screw thread 11.
In the specific implementation, the diameter of thread of the positive external screw thread 11 and reverse external screw thread 12 is 12 mm -150 mm.
In the specific implementation, the inner chamber inwall material of the batcher housing 1 is 304 or 316 rustless steels.
In the specific implementation, the motor 3 adopts vertical machine, and the outfan of the vertical machine is provided with 17：1 gear subtracts
Fast machine.
In the specific implementation, the bottom of the batcher housing 1 is provided with balance pad 13.
In the specific implementation, it is in the structure of falling quadrangular frustum pyramid shaped that the batcher housing 1 is overall.
In the specific implementation, material is delivered to feed bin by conveying equipment through the powder input port above screw(-type) feeder
In.For ensureing that feed bin, all the time full of material, is provided with low material position machine in warehouse.The power of motor drives spiral shell by connecting gear
Rotation feed appliance rotation, the material in barrel do forward axial migration along barrel, finally under the promotion of reverse-flighted screw helical blade
Flow out from powder carry mouth.Due to the effect of material gravity itself and its frictional force to barrel, material is not revolved with spiral
Turn, its working condition is for linear motion the same along screw rod similar to not revolvable powder.In fact, in course of conveying material
The motion of granule is simple linear motion due to affecting by rotating screw push rod, not, but the rotation shape with screw rod
Into a space motion.Powder can be extruded so as to be blocked in screw gap with barrel in progradation, and this utility model sets
Reversely periphery screw rod is put, the powder of blocking is scraped.Additionally, in course of conveying, also easily occurring blocking, the gas of setting in pipeline
Mouthpiece can be prevented effectively from there is this problem.
Above content is with reference to specific preferred implementation further detailed description of the utility model, it is impossible to
Assert that this utility model is embodied as being confined to these explanations above-mentioned.Common skill for this utility model art
For art personnel, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should
It is considered as belonging to protection domain of the present utility model.
