Description
Technical field
The present invention relates to gas conveying sealing arrangement, particularly relate to and close for gas in gas conveying a kind of Pneumatic conveyer that wind or solid material and air-flow carry out mixing.
Background technology
At present, powder material carries out, in the process of gas conveying, mainly containing following technical matters:
1, because gas adopts line seal, and material adopts the way of gas car or machinery conveying to carry, and because carrying the pressure of gas high, when reinforced, gas can leak along material inlet, causes environmental pollution, causes pressure relief of gas, cannot reach the object of conveying;
2, now widely used is mechanical seal, and as air sealer, mechanical encapsulation devices wearing and tearing are large, and service life is short, and the poor sealing performance of equipment.Meanwhile, mechanical seal is sealing in motion, for the strong material of water suction, poor fluidity, the easy seize of material on the go that stickiness is high, can not realize continus convergence.
Summary of the invention
In order to overcome the deficiencies in the prior art, the object of the present invention is to provide a kind of Pneumatic conveyer, can various material be applicable to, not seize in conveying, realized hermetic mechanical wearing and tearing continus convergence.
Object of the present invention realizes by the following technical solutions:
A kind of Pneumatic conveyer, comprise S. A., for driving the driver train rotated into S. A., housing and elastic seal diaphragm, driver train drives with S. A. and is connected, rotation axis seal is connected to one end of housing, and this S. A. stretches into housing, the wall body of housing has feeding mouth, the S. A. just right with this feeding mouth is provided with feed auger, the other end of housing is provided with discharging opening, S. A. near this discharging opening is provided with discharging spiral, elastic seal diaphragm resilient sleeve to be loaded on the S. A. between discharging spiral and feed auger and to be sealed and matched with inner walls, seal area is formed in housing between this elastic seal diaphragm and feed auger.
Preferably, elastic seal diaphragm conically, has towards the large mouth of seal area and the osculum towards discharging spiral.
Preferably, driver train comprises motor and speed reducer, and the mouth of motor docks with S. A. through reductor.
Preferably, relative with elastic seal diaphragm housing is provided with inspection door.
Preferably, discharging opening is provided with stirring scraper.
Preferably, feeding mouth extends to form annular port around housing periphery.
Compared to existing technology, beneficial effect of the present invention is:
The present invention is after material enters seal area by feed auger, when not being full of seal area, by elastic seal diaphragm, seal area is sealed, prevent the high pressure gas of discharging opening from sealing in seal area, after material is full of seal area, material self formation stock column achieves and realizes material envelope to the sealing of seal area, and material enters discharging spiral by strutting elastic sealing film under the squeezing action of feed auger, export through discharging opening again, thus the continuous sealing that can realize in material conveying process, and can not cause and leak out because mechanical rotation produces air gap, also inleakage will be caused to increase because of mechanical wear, and the sealing means of this nothing wearing and tearing is realized by above-mentioned material envelope, its service life is extended, and, due to sealing and the pusher effect as required of this elastic sealing film, make the present invention can adapt to water suction strong, poor fluidity, the material that stickiness is high, be applicable to various material, seize phenomenon can not be produced and cause seal failure.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of Pneumatic conveyer of the present invention.
In figure: 1, S. A.; 2, driver train; 21, motor; 22, reductor; 3, housing; 31, feeding mouth; 32, discharging opening; 33, seal area; 4, elastic seal diaphragm; 41, great Kou; 42, osculum; 5, feed auger; 6, discharging spiral; 7, inspection door; 8, scraper is stirred.
Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the present invention is described further:
A kind of Pneumatic conveyer as shown in Figure 1, comprise S. A., for driving the driver train rotated into S. A., housing and elastic seal diaphragm, driver train drives with S. A. and is connected, rotation axis seal is connected to one end of housing, and this S. A. stretches into housing, the wall body of housing has feeding mouth, the S. A. just right with this feeding mouth is provided with feed auger, the other end of housing is provided with discharging opening, S. A. near this discharging opening is provided with discharging spiral, elastic seal diaphragm resilient sleeve to be loaded on the S. A. between discharging spiral and feed auger and to be sealed and matched with inner walls, seal area is formed in housing between this elastic seal diaphragm and feed auger.
After material enters seal area by feed auger, when not being full of seal area, by elastic seal diaphragm, seal area is sealed, prevent the high pressure gas of discharging opening from sealing in seal area, after material is full of seal area, material self formation stock column achieves and realizes material envelope to the sealing of seal area, and material enters discharging spiral by strutting elastic sealing film under the squeezing action of feed auger, export through discharging opening again, after output for gas and vapor permeation, thus the continuous sealing that can realize in material conveying process, and can not cause and leak out because mechanical rotation produces air gap, also inleakage will be caused to increase because of mechanical wear, and the sealing means of this nothing wearing and tearing is realized by above-mentioned material envelope, its service life is extended, and, due to sealing and the pusher effect as required of this elastic sealing film, make the present invention can adapt to water suction strong, poor fluidity, the material that stickiness is high, be applicable to various material, seize phenomenon can not be produced and cause seal failure.
Preferred structure as elastic seal diaphragm of the present invention: the elastic seal diaphragm of this example conically, has towards the large mouth of seal area and the osculum towards discharging spiral.The shape of this elastic seal diaphragm is arranged, and makes it can bear larger feed pressure, to make material strut this elastic seal diaphragm when being full of seal area, to guarantee that zero leaks out.This elastic seal diaphragm can adopt to be possessed elastomeric steel disc and makes.
As preferred embodiment, the driver train of this example comprises motor and speed reducer, and the mouth of motor docks with S. A. through reductor.Motor produces rotary driving force, drives reductor to be rotated in deceleration, to export high pulling torque by S. A., drives mass transport to advance.
For ease of maintenance, the housing relative with elastic seal diaphragm is provided with inspection door, and opening inspection door can safeguard elastic seal diaphragm, handled easily human users.
For clearing up material, prevent feed blocking at discharging opening, discharging opening is provided with stirring scraper, and this stirring scraper can adopt existing conventional scraper, as the rotating mechanism of scraping blade, scraper.
For convenience of pan feeding, feeding mouth extends to form annular port around housing periphery, to make all can send into material in the surrounding of housing.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of the claims in the present invention.
