Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
Embodiment 1
As Figure 1-4, a kind of portable grinding wheel sander dust collect plant, comprises dust gathering arrester 1, cover plate 2, deflector 3 and discharge 4.Dust gathering arrester 1 is semi-hermetic type emery wheel dust gathering arrester, dust gathering arrester 1 is fixed in wheel sander frame, cover on the emery wheel 9 of wheel sander, dust gathering arrester 1 outer profile curve is involute or off-centre operation, be convenient to air-flow collect and reduce drag losses, anterior employing and the straightway of contact of a curve, increase the volume of air collecting chamber, make dust recycling and deceleration, be convenient to gas collection air-flow and collect dust.Dust gathering arrester 1 available metal plate is processed, also can with nonmetallic materials compression moldings such as plastics.
Cover plate 2 is connected with flange bolt with dust gathering arrester 1, forms a semi-enclosed space on emery wheel 9 top.Dust gathering arrester 1 can be separated with cover plate 2, so that change or maintenance emery wheel.Dust gathering arrester 1 upper weld deflector 3, deflector 3 plate face extended line and emery wheel 9 arc-shaped surface tangent, effect guides air-flow and chamber before and after isolated dust gathering arrester, reduces process gas flow, reduce the drag losses of gas.Discharge 4 is arranged on dust gathering arrester 1 gabarit above the deflector 3 on the surface, and discharge 4 be tapered, so that guiding fluid reduce drag losses.Discharge 4 is connected by air hose (comprising metal, rubber, plastics etc.) and deduster dedusters such as () whirlwind, filter bag, filter cylinders (not drawing in figure), by air hose, the dust-laden exhaust gas of collection is sent to deduster and carries out dedusting.Consider emery wheel 9 wearing and tearing when scrapping diameter change greatly, dust gathering arrester is designed to can the structure that moves up and down of vertical direction.
For reducing air hose wearing and tearing, useable holder holds up air hose.
This dust collect plant also comprises pilot pin 5 and strip slot 7, and pilot pin 5 and strip slot 7 are arranged on the left of dust gathering arrester 1, and grinding wheel spindle is through strip slot 7.Fit with the connecting plate 10 be fixed on abrasive machine support on the left of dust gathering arrester 1, connecting plate 10 has gathering sill 8, pilot pin 5 is placed in gathering sill 8, when diameter after emery wheel 9 surface abrasion diminish or change new grinding wheel diameter become large and emery wheel shaft core position is changed up and down time, dust gathering arrester 1 keeps the gap of bottom and surface of the work constant by Gravitative Loads.The effect of pilot pin 5 makes to locate before and after dust gathering arrester 1, and restriction set dust hood 1 moves forward and backward, and dust gathering arrester 1 is not contacted with the grinding wheel spindle rotated, and can only paste connecting plate 10 lower slider on the surface.The effect of strip slot 7 is not by the restriction of grinding wheel spindle in short transverse when dust gathering arrester 1 is moved up and down.
4 rollers 6 are housed bottom dust gathering arrester 1, ensure the gap remained constant with buffed surface bottom dust gathering arrester 1.
First blower fan exhausting is started during work, in dust gathering arrester 1, negative pressure is formed by air hose, dust gathering arrester 1 surrounding flow enters dust gathering arrester 1 by surface of the work and dust gathering arrester 1 time edge under atmospheric pressure effect, forming Dual-Phrase Distribution of Gas olid in cover together with the mix dust of grinder buffing, under blower fan draft effect, enter deduster through dust gathering arrester 1, discharge 4, air hose etc.
When abrasive machine employing diameter is the emery wheel of 300mm, and when rotating speed is 1440 revs/min of polishing rusty plates, adopt this dust collect plant, when gas collection amount is 300m3/h, its dust collecting effect can reach 90 ~ 95%.
Leak out for reducing dust gathering arrester 1 sidepiece gap, dust gathering arrester 1 sidepiece can adopt rubber, felt, plastics or hairbrush to carry out auxiliary seal.
