Description

Shaft furnace material cup lever boom hoisting

Technical field

Feeding device is the utility model is related to, is exactly a kind of shaft furnace material cup lever boom hoisting.

Background technology

Material mixer shaft furnace is that intermittent feeding and continuous output kiln gas, the continuous air intake in bottom are born stone side by side at the top of one kind The limekiln of ash, kiln top keep slight positive pressure state, and there is material cup headstock gear control material to be acted on into kiln is interior, while can prevent The excessive and outside air of kiln gas entrainment dust enters in kiln to be impacted to kiln gas concentration.

Mixed material is lifted through loader winch, along track drawing to kiln top, mixed material is poured into revolving hopper, so After skip car is run 5 seconds downwards afterwards, drive revolving hopper to rotate certain angle by motor and stop, revolving hopper is together with cloth Glassware does the revolution of four different angles in a dust cycle, and in a dust cycle, distributing device can Circumferentially different point cloth.Due to the revolution of revolving hopper, eliminating material, charge level tilts in revolving hopper and lumpiness is inclined The influence of analysis, so that material is uniformly distributed in kiln on cross section, expects that cup is in when revolving hopper rotates and close State, revolving hopper drive material cup and suspension rod to rotate together, when skip car comes downwards to filling position, pass through mechanical interlocks The unlatching of material cup is driven, compound is uniformly sprinkled into through spreading stone implement in kiln, therefore expects cup headstock gear in limekiln steady production On play critically important effect, material cup headstock gear structural representation is as shown in Figure 1.

But expect cup headstock gear in use often there arises a problem that：

First, lever produces under suspension rod, material cup, sheath gravity and the effect of weighted lever power at lever central positioning hole Stress concentration, under frequent alternate stress, lever is easily broken.

Second, lever rotation support zone is simple in construction, carried out from the center positioning hole of alignment pin and lever with, no profit Sliding device, the center positioning hole and alignment pin that lever is easily caused during lever rotation produce abrasion, need to be to alignment pin, thick stick Bar is frequently changed.

Third, it is monorow tooth for controlling the drive sprocket of weight counterbalance operation, driving chain is single strand chain, is used in skip car Property impact force action under easily occur chain link breakage phenomenon, cause the parts damages such as feeding tie rod.

Above Railway Project causes to expect that the maintenance of cup headstock gear is cumbersome, and maintenance workload is big, while causes one to production It is fixing to ring.
