Abstract
The utility model relates to a drum wheel powder feeder, in particular to a gas-carrying type drum wheel powder feeder which is used for feeding powder by dint of the gas. The gas-carrying type drum wheel powder feeder comprises a powder bucket, a powder inlet pipe, a powder feeding wheel, a powder discharging cavity and a powder discharging opening which are installed together, an air inlet opening is respectively arranged on the outer wall on the top cover of the powder bucket and at the upper part of the powder discharging cavity; a plurality of small grooves are arranged on the side surface on the periphery of the powder feeding wheel. The drum wheel powder feeder has the following technical effects that the powder feeding wheel with different specifications can be designed according to the size of the particle of the powder, the speed rate of the power feeding can be accurately controlled through adjusting the rotating speed of the powder wheel, the diameter of the powder inlet pipe and a clearance between a powder leaking hole and a powder wheel, the more continuous powder flow status can be obtained, not only the powder feeding quality can be improved, but also the demand of the manufacture can be adapted, and the adjusting method is flexible. The drum wheel powder feeder has the advantages that the mechanical structure is simple, the reliability is high, and the cost is low.
Description
Technical field
The utility model relates to a kind of drum powder feeder, in particular, is a kind of carrier gas formula drum powder feeder of being assisted powder feeding by gas.
Background technology
The drum powder feeder is the visual plant of laser cladding technology, be widely used in the industrial production at present, but the drum powder feeder is in the powder feeding process, because only the gravity by powder self is along with the rotation of drum flows into the powder chamber, therefore, powder extruding appears in the drum powder feeder of this structure easily in the powder feeding process, phenomenon such as stop up, powder feeding is irregular.
Summary of the invention
The utility model is in order to overcome weak point of the prior art, a kind of carrier gas formula drum powder feeder that adopts mechanics of machinery and gasdynamics mode to carry out powder feeding is provided especially, this powder feeder not only can change the speed of powder feeding, and regularly can also improve the quality of powder feeding at powder feeding rate one.
The technical scheme that the utility model is taked to achieve these goals is: a kind of carrier gas formula drum powder feeder, comprise the powder bucket, powder inlet pipe, powder feeding wheel, powder delivery chamber and the meal outlet that are fixedly installed togather, it is characterized in that, on the outer wall on the top cover of described powder bucket and top, powder delivery chamber, be respectively equipped with inlet mouth; On the side of described powder feeding wheel circumference, evenly be provided with several sulculuses.
The utlity model has following technique effect: can be according to the size of powder particle, the powder feeding wheel of design different size, by rotating speed, powder inlet pipe diameter and the powder leakage hole of adjusting powder wheel and the gap between the powder wheel, just can accurately control powder feeding rate, can obtain more successive powder stream mode, not only improved the powder feeding quality, and adapted to the needs of producing, regulative mode is flexible.And it is simple to have physical construction, reliability height, low cost and other advantages.
Description of drawings
Fig. 1 is the utility model structural representation, and as Figure of abstract.
Fig. 2 is the enlarged view of powder feeding wheel among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated:
With reference to Fig. 1, the utility model is to rely on gas to assist to carry powder.The sulculus that evenly to be provided with 28 volumes on powder feeding wheel 3 circumference be v, during powder feeder work, open pressurized gas, gas is entered in powder bucket 1 and the powder delivery chamber 4 by inlet mouth 6,7 respectively, powder by powder bucket 1 in the dirty sulculus 8 that advances on the powder feeding wheel 3 of deadweight and the effect of pressurized gas, along with the rotation sulculus 8 interior powder of powder feeding wheel 3 flow into powder delivery chamber 4 successively.Compressed air suits in powder delivery chamber 4, and keep pressure stable, the gas-entrained powder flows out from the meal outlet 5 of 4 lower ends, powder delivery chamber.Powder feeding rate just can accurately be controlled in the gap that rotating speed, powder inlet pipe 2 diameters and powder leakage hole by regulating powder feeding wheel 3 and powder feeding wheel are 3.Be formulated as: n is a rotating speed in the Mp=nmv ρ formula; M is the groove number; V is the groove volume; ρ is a tap density; Mp is a powder feeding rate.
In general, the size that changes rotation speed n just can change powder feeding rate, but at powder feeding rate one regularly, the volume that increase groove number reduces groove simultaneously can improve the powder feeding quality, obtains more successive powder stream mode.Different in addition powder can adopt the powder feeding wheel of different size, because powder particle is big, it is little that available slot is counted m as the big powder of granularity, the powder wheel that volume v is big, the powder that granularity is little is because particle is tiny, and is mobile poor, can adopt groove to count the big little powder feeding wheel of volume v of m.
