Summary of the invention
The technical problem to be solved in the present invention just is: propose the new mode of a kind of lifting and conveying particle, powder class material and utilize the formed granular powder device of the method, utilize this granular powder device serially particle, powder class material to be delivered to eminence from lower.The granular powder apparatus structure is simple, easy and simple to handle and system energy consumption is low.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
A kind of method of utilizing rise in vibration particle, powder class material: adopt a top seal, bottom opening standpipe as raising pipe, vertically the bottom of pipe is put into particle, the powder material bed of material and applied vibration along tube axis direction to promoting standpipe, vibration causes the fluctuation of pressure in the pipe, under the effect of fluctuation of pressure, particle, powder material can rise along standpipe, form the pump-absorb action to particle, powder material.Promoting between standpipe and the gravity direction also can have certain inclination angle, and namely promoting between standpipe and the vertical direction to have certain angle.
The granular powder device that utilizes as mentioned above the method for rise in vibration particle, powder class material to adopt: comprise promoting standpipe, discharge tipping tube, blow-off valve and vibrating mechanism, the sealing of lifting riser top, promoting the riser top side is connected with the discharge tipping tube, vibrating mechanism drive to promote standpipe and makes periodic vibration along the standpipe axis direction, and particle, powder class material are promoted and carry.
System vibration mechanism can apply vibration to promoting standpipe separately, also can apply vibration to the granular powder bed of material separately, perhaps applies vibration to promoting standpipe and the granular powder bed of material respectively simultaneously.
Promoting between standpipe and the gravity direction has 0 ° to 60 ° inclination angle, and namely promoting has 0 ° to 60 ° angle between standpipe and the vertical direction.
Promote standpipe and can adopt pipe, square tube or other cross sectional shape pipe.
The discharge tipping tube can adopt pipe, square tube or other cross sectional shape pipe.
Compare with existing particle, powder batch (-type) bont, but the invention has the advantages that continuous uniform promotes particle, powder class material.Compare with particle, powder pneumatic feeding device, the invention has the advantages that and can realize that close phase particle promotes, system energy consumption is low, and apparatus is simple, and pipe wear is little.
The working process of granular powder device: the granular powder device is promoted the riser bottom open end put into particle, powder material bed, close the blow-off valve on the discharge tipping tube; Open vibrating mechanism, so that promote standpipe along self axis direction vibration-generating; Promote the interior gaseous tension of standpipe and fluctuate with generation of vibration, the particle that promotes in the standpipe rises in standpipe gradually.When promoting standpipe endoparticle or powder and rise to the tipping tube mouth of pipe, the particle, the powder that promote in the standpipe can be along the discharge tipping tubes toward current downflow under Action of Gravity Field; When filling up particle or powder in the discharge tipping tube, open blow-off valve, particle or powder flow out continually from the outlet of discharge tipping tube, and namely the granular powder device is started working.
The principle of work of granular powder device: after vibrating mechanism is opened, promote standpipe and do periodic vibration along self axis.When the lifting standpipe upwards vibrates, promote and form certain negative pressure in the standpipe pipe, namely intraductal atmospheric pressure is less than the outer air pressure of pipe.The pipe in negative pressure so that granules in pipe along with standpipe rises together.When the lifting standpipe vibrated downwards, standpipe fell go back to promoting the front position prior to granules in pipe, and it is loose by particle or powder tamp on every side that standpipe lower end particle or powder promote formed material.Although this moment, to promote the standpipe internal pressure be malleation, the position when granules in pipe can't be back to the initial upward movement of standpipe, namely granules in pipe is with respect to the outer bed particle of the pipe segment distance that rises.With the carrying out of vibration processes, the particle, the powder material layer height that promote in the standpipe rise gradually.
The fluctuation of pressure that promotes in the standpipe is the necessary condition that particle, powder rise, and therefore, when the granular powder device is opened, need close blow-off valve.Standpipe to be hoisted, discharge tipping tube are opened blow-off valve after being full of by particle or powder material again.
After particle, powder material are full of the discharge tipping tube, even Open valve promotes riser top and can form certain fluctuation of pressure equally, so particle, constantly edge lifting standpipe rising of powder material, and flow out from the discharge tipping tube.
During granular powder device Halfway Stopping, remain in the tipping tube by particle, powder material and fill, therefore, start pump and can again " close-open " valve.
Change vibration amplitude or the frequency of vibrating mechanism, promote the endocorpuscular ascending velocity of standpipe and also can change.Therefore, can realize the pump delivery adjusting by regulating vibration parameters.
