The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
embodiment 1
The present embodiment silicon carbide micro-powder deironing apparatus is comprised of driving-belt, magnetic roller, non magnetic roller, the first regulating wheel, the second regulating wheel, vibratory sieve, the first permanent magnet, the second permanent magnet, the first collector, wind shower pipe, expansion chamber, water shower pipe, the second collector, vibrator, iron powder pond, warm-air pipe and air blast; Described driving-belt is inverted trapezoidal setting, and described magnetic roller and non magnetic roller support compare Chang base, conveyer belt top, makes in horizontal tensioning state, and the first regulating wheel and the second regulating wheel support compare Duan base, driving-belt bottom, make in horizontal tensioning state; Described vibratory sieve is positioned at driving-belt top near magnetic roller one side, and described the first collector is positioned at magnetic roller below; Described the first permanent magnet and wind shower pipe lay respectively at inner side and the outside of conveyer belt between magnetic roller and the first regulating wheel, described the second permanent magnet and water shower pipe lay respectively at inner side and the outside of conveyer belt between the first regulating wheel and the second regulating wheel, and described expansion chamber and the second collector are separately positioned on again the below of wind shower pipe and water shower pipe; Described vibrator and iron powder pond lay respectively at inner side and the outside of conveyer belt between the second regulating wheel and non magnetic roller, and described warm-air pipe is positioned at the below of non magnetic roller, are communicated with air blast.
Described wind shower pipe pressure is set to 0.05 ~ 0.1MPa, and described water shower pipe water side is provided with atomizer.The sieve number of vibratory sieve is determined according to the carborundum granularity upper limit.Described magnetic roller has ferromagnetism and is used for adsorbing the iron powder in silicon carbide micro-powder, drives driving-belt to rotate as driving wheel simultaneously, and non magnetic roller, for not having magnetic driven pulley, impels driving-belt cycle rotation.When the first permanent magnet and the second permanent magnet drench wind pouring and water, iron powder can be adsorbed on driving-belt and not come off.
Production process is as follows:
(1) first, the silicon carbide micro-powder for the treatment of deironing is passed into vibratory sieve to be sieved, the silicon carbide micro-powder containing iron powder that is loose condition (of surface) after screening is fallen on driving-belt, under the driving and absorption of magnetic roller, silicon carbide micro-powder and iron powder obtain initial gross separation, iron powder is attracted on driving-belt, and carborundum falls into the first collector of magnetic roller below and is collected;
(2) then, then with the blast of wind shower pipe, blow away the partially carbonized silicon powder adhering in the first permanent magnet absorption iron powder on driving-belt, and silicon carbide micro-powder wind pouring being blown off by expansion chamber collects;
(3) then, in iron powder after wind drenches, still contain some silicon carbide micro-powder, the atomized water spraying by water shower pipe again washes away the silicon carbide micro-powder adhering in the iron powder of the second permanent magnet absorption on driving-belt, and silicon carbide micro-powder water wash being fallen by the second collector collects; Through wind pouring and water, drench after processing, on driving-belt, the silicon carbide micro-powder of iron powder adsorption is fully collected;
(4) last, the iron powder that loses magnetic-adsorption on driving-belt falls into iron powder pond and is collected, and meanwhile, vibrator is by imposing on the pressure exciting force of driving-belt, make iron powder on driving-belt fast, fall fully, guarantee that the iron powder on driving-belt is collected completely; Then, the driving-belt surface after warm-air pipe is collected to iron powder by air blast blasts hot blast, and driving-belt is carried out to heated-air drying, and driving-belt goes to vibratory sieve blanking place by non magnetic roller and works on after hot blast is fully dry, and deironing automatic cycle is carried out.
The utility model is not limited to the above-mentioned specific embodiment, and those skilled in the art also can make multiple variation accordingly, but any and the utility model are equal to or similarly change and all should be encompassed in the scope of the utility model claim.
