Description
Technical field
The utility model relates to a kind of powder conveying apparatus, and concrete is a kind of granular material delivery system.
Background technology
Existing granular material mode of movement comprises: inhale and send formula, pressure sending type, hybrid and fluid delivery type four kinds of forms.1, inhale and send formula to work as when gaseous tension is lower than bar pressure in delivery duct, be called that formula Geldart-D particle is sent in suction.When after fan starting, when reaching certain degree of vacuum in pipeline, the air in air is portable enters pipeline with material by suction nozzle, and is transported to the disconnector of throw-off end along pipeline.In the separator, material and air separation, isolated material is drawn off by separator bottom, and air is by being discharged in air through blower fan after dust exhaustor dedusting.Inhale and send the major advantage of formula pneumatic transport equipment to be that feeding device is simple, simultaneously from a few absorbing material, and size and position limitation can not asked by suction place sky.Its major defect is because the degree of vacuum in pipeline is limited, therefore fed distance is limited; The sealing requirements of device is very high; When the gas by blower fan does not have fine dedusting, will speed up blower fan wearing and tearing.2, pressure sending type: when gaseous tension in transfer line is higher than barometric pressure, be called pressure sending type Geldart-D particle.Pressurized air inputs in loader by blower fan, makes material and gas and vapor permeation, and the gas material of mixing enters disconnector through delivery duct.In disconnector, gentle stopping is separated material, and material is drawn off by separator bottom, and gas is discharged in air after dust exhaustor dedusting.The major advantage of pressure sending type Pneumatic conveyer is that fed distance is far away; Can simultaneously mass transport to a few place.Its major defect is that loader is more complicated; Can only simultaneously by a feed.3, hybrid: hybrid Geldart-D particle send formula and pressure sending type to constitute jointly by suction.Send part in suction, be negative pressure in delivery duct, material is sucked by suction nozzle, enters disconnector be separated through pipeline.In force feed part, be malleation in delivery duct, the material drawn off be sent to disconnector be separated by separator bottom.Negative pressure in pipeline and the malleation in pipeline are all caused by same Fans.The major advantage of hybrid Pneumatic conveyer from a few absorbing material, material can be transported to a few place simultaneously again, and fed distance is far away.Its major defect is containing expecting that gas is by blower fan, making blower fan wear and tear and accelerate; Whole appliance arrangement is more complicated.4, fluid delivery type: fluid delivery type Geldart-D particle is a kind of deformation type of material suspended conveying, and air conveyer flume is exactly this feedway.Its effect is little for air open close too much lonely L air-permeable layer filled in people's granular material in enormous quantities, makes material become similar fluid properties, thus can flow to low side by the high-end of trough.The conveying of material group, also referred to as bolt stream Geldart-D particle, is the material bolt by gaseous tension, the material in pipeline being divided into many interruptions, and is promoted along Cemented filling by strength.
Concrete patented technology, a kind of device for pneumatic conveying loose unpacked material especially granular material disclosed in 101511712A, there is delivery duct, conveying gas source and at least one extracting position, this delivery duct determines the transport path for loose unpacked material, this conveying gas source is connected on delivery duct and along the direction input of transport path and carries gas, is derived by gas by this extracting position from delivery duct.Propose by the present invention, multiple extracting position is arranged on delivery duct along spaced the turning up the soil of transport path, and described extracting position can adjust flux.Thus, present invention achieves and controlledly from delivery duct, take out excessive gas.Can gas velocity be reduced thus, make conveying keep tranquil and stable.Can cancel thus up to now in order to the cross-sectional plane maintaining the delivery duct required for calmness and stable conveying hierarchically becomes large along transport path.This granular material device, there is complex structure, transport efficiency is low, and the problem easily occurring dust blocking, reveal.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of granular material delivery system, can overcome the above-mentioned defect of prior art.
For achieving the above object, the utility model provides following technical scheme:
A kind of granular material delivery system, comprise pressure fan, feed arrangement, powder material storehouse and transfer line, entrance and the pressure fan air outlet of described transfer line seal UNICOM, the powder inlet point of described transfer line and feed arrangement seal UNICOM, the discharging opening of described transfer line and powder material storehouse seal UNICOM, described feed bin top is provided with air outlet, and the air outlet of described feed bin is provided with the choke plate of alternative arrangement, forms the damping air flue of a S type between described choke plate.
Further, described feed arrangement comprises barrel, is provided with pore mesh screen bottom described barrel, and described barrel top is provided with feeder hopper, and described feeding funnel bottom part is provided with discharge nozzle, and described discharge nozzle is arranged in barrel.
Further, described feeder hopper top is also provided with the seal cover cap preventing dust from revealing.
Further, be also provided with the hydraulic efficiency gear for pressing down powder in described barrel, described hydraulic efficiency gear is arranged on feeding funnel bottom part.
Further, described pressure fan is roots blower.
The beneficial effects of the utility model are: granular material delivery system of the present utility model is by the choke plate that is crisscross arranged by the air outlet at feed bin, form the damping air flue of a S type between choke plate, can effectively prevent the wind of going out from feed bin from taking powder out of.
