Description
Technical field
This utility model relates to a kind of screw(-type) feeder with anti-channeling airway dysfunction, belongs to dispensing conveying skill
Art field.
Background technology
Screw(-type) feeder be a kind of current stabilization collecting powder material conveying, Weighing and fixing quantity be one
The conveying equipment of body, its simple in construction, reliable, control accuracy is high, be easy to device feed, unload
Material and centre carry and low cost of manufacture, thus the powder body thing being applicable under various industrial production environment
The continuous metering of material and dispensing.In addition material can also be stirred in course of conveying by screw(-type) feeder
Mix, mix, heat, the operation such as cooling, adjusted by the control of material valve or the configuration of frequency conversion motor
Joint mass flow, is therefore widely used in the solid bulk of the industries such as building materials, metallurgy, electric power, chemical industry
The conveying of material.
Screw(-type) feeder is usually used in the charging of rotary furnace and transports with discharging, when some special thing in rotary furnace
When material requires isolation air in course of reaction, then screw(-type) feeder just needs in material conveying process
Seal, to prevent air from scurrying in rotary furnace from the import or export of screw(-type) feeder, the most also
The gas preventing reaction from generating escapes in rotary furnace.At present, generally use two kinds of methods that spiral is given
Material machine carries out encapsulation process, and one is to install sealing additional before the import of screw(-type) feeder or after outlet
Equipment, two is to be in tilted layout by screw(-type) feeder, utilizes materials inside to seal.But both sides
In place of method all Shortcomings, the former needs additionally to arrange sealing device, adds equipment cost undoubtedly；
Although the latter is without increasing equipment, but the arrangement tilted is not particularly suited for all of transportation environment.
For overcoming deficiencies of the prior art, Chinese patent literature CN 203629321U is open
The material seal apparatus of a kind of conveying worm, it is by the method being welded on screw conveyor housing for a pair
Blue and the middle part that is clamped in housing or near the position of outlet, this material seal apparatus includes half conical shell,
