The principle of work of the utility model is explained as follows:
Powder is carried powder entering valve 13 to enter into mixing by inlet valve 3 or strength and is carried in the storehouse 1, and the unnecessary air in the mixing conveying storehouse 1 is through blow off valve 2 discharges.When inlet amount reaches setting value, stop charging and close inlet valve 3 or strength conveying powder entering valve 13.After feed operation finishes; The compressed air control valve of air supply system begins the pulse conducting; Pure air is through control cock enters into the annular air channel of annular air channel and supplemental inflatable device 5 of main gas charge device 7 with the form of pulse in; Then, pressurized air sprays through the main gas charge hole and the supplemental inflatable hole of main gas charge device 7 and supplemental inflatable device 5 again.By the gas of the supplemental inflatable hole of supplemental inflatable device 5 ejection at first along supplemental inflatable ring inner cylinder with mix the inboard high-speed cruising of the warehouse undergauge tube of carrying storehouse 1; The pulse screw up current that formation speed is very big; This high-speed pulse spiral up current concentrates on and mixes on the inside face of carrying storehouse 1 warehouse cylinder; When this air-flow ran to the inside face of warehouse undergauge tube, because the air-flow effect of inertia, it will be along the inside face operation of the warehouse undergauge tube of truncated cone; It moves along the inside face of warehouse cylinder again when this air-flow further runs to the warehouse cylindrical portions may of mixing conveying storehouse 1; Thisly can arrive or near the upper surface of material, make and mix near carry 1 inwall of storehouse all powders and fully mix, to improve its flowing power with air along pulse screw up current that mix to carry storehouse 1 inside face operation.By the gas of the main gas charge hole of main gas charge device 7 ejection, because the bleeder valve 8 of main gas charge device 7 bottoms cuts out, it can only form Parallel airflow vertically upward along the inside face upward movement of the main gas charge ring inner cylinder of main gas charge device 7.When married operation has just begun; Because the air pulse of main gas charge device 7 and supplemental inflatable device 5 is synchronous, can observe to mix and carry the up-down of pulsing synchronously of storehouse 1 powder around inboard and base pipe 4 interior powders, but passing in time; Mix and carry the storehouse each amplitude that rises of 1 inboard powder all around to reduce; Decline scope increases, and the amplitude that the powder in the base pipe 4 then rises at every turn increases, and decline scope reduces.Several pulsed operations mix and carry storehouse 1 inboard powder all around to begin only to do the descending motion of pulsing, and the powders in the base pipe 4 began pulsation ejection fast after the cycle.This mainly is that after powder material gas inside content was increased to certain value, the distance between the powder particle increased because air pulse constantly puts on the air to mixing the powder of carrying in the storehouse 1; Powder particle is in suspended state basically, cubic expansion, and the internal friction coefficient of powder sharply descends; But the friction coefficient of powder and container side wall changes and is little; Therefore, the rising resistance that mixes near the powder in conveying 1 center, storehouse sharply diminishes, and carries near storehouse 1 inboard powder rising change in resistance little and mix; Thereby make a large amount of powders from mix carrying the center pulsation ejection in storehouse 1, and to around be scattered.Along with a large amount of powders sprays from the center pulsation that mixes conveying storehouse 1, the rising resistance that mixes near the powder in center of carrying storehouse 1 further reduces, therefore; The incipient stage inventory of each ejection increases gradually; Mix and carry storehouse 1 inboard weight of material all around constantly to become big, the powder ascensional range at this place begins to reduce, simultaneously; Because near the powder that is positioned at mixing conveying 1 center, storehouse is whole pulsation rising; Its bottom will produce corresponding space, and the powder around this space will automatically enter under the effect of its ambient pressure in this space, because mixing conveying storehouse 1 lower periphery powder moves the space that stays then by the powder whereabouts filling on its top to the center; Making to be positioned to mix carries the amplitude of storehouse 1 powder rising all around constantly to reduce; Disappear up to its upward movement, and its decline scope reaches a certain fixed value at last in continuous increase.Final material forms the pulsation circulation in mixing conveying storehouse 1.When material movement is near mixing conveying 1 bottom, storehouse, concentrate, focus near the powder upward movement of warehouse bottom centre, and do strong the upset to the warehouse center; When powder moves to the port of base pipe 4, from the ejection of the port of base pipe 4, and to around be scattered; Last move downward along the outside of base pipe 4 again; Through powder material is constantly concentrated in mix carrying storehouse 1, overturn strongly and be scattered, thereby realized the married operation of powder material.This process is through repeatedly repeatedly, and material can obtain higher degree of mixing.The effect of base pipe 4 be when powder is gentle flow into base pipe after, it just is limited in the pipe, and can level leak, and has improved work efficiency.Simultaneously,, mix very big that the volume of carrying the storehouse does, greatly improved the working ability of equipment thereby can make because the restriction of maximum jetting height and minimum spray velocity has been eliminated in the existence of base pipe 4.Effluent air is drained into the atmosphere through blow off valve 2 from powder top.Behind the mixing of materials EO, close blow off valve 2, open bleeder valve 8, simultaneously, pulse is opened strength and is carried pressurizing valve 12 and strength to carry powder shutoff valve 11, and the form of material with the material bolt drawn off, and is transported to and specifies in the feed bin.After conveying operations finishes, close bleeder valve 8, strength conveying pressurizing valve 12 and strength and carry powder shutoff valve 11, it is ready for next cycling to open blow off valve 2.
