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, suspension rod head support rotary part structure is relatively easy, lack sealing, oily part, due to lime
Kiln flour dust on top is more, and dust enters inside rolling element, when expecting that cup rotates with rotating bucket, into the dust inside rolling element
Particle meeting build-up of pressure bearing damage, and then cause the abrasion of suspension rod spindle nose, the first-class part of connection, needed in regular maintenance frequently
Each part is periodically changed.
Above mentioned problem causes to expect that the maintenance of cup headstock gear is cumbersome, and maintenance workload is big, while it is fixing to cause one to production
Ring.
Utility model content

In order to solve the above technical problems, the utility model uses following technological means：
A kind of shaft furnace material cup derrick rig, including suspension rod, the material cup that the bottom of suspension rod is connected, described suspension rod are divided into
Upper hanger, lower suspension rod；The top of upper hanger and one end of lever connect, and the bottom of upper hanger and the top of lower suspension rod pass through flange
Connection；The bottom of upper hanger is connected by bearing, bearing block with material cup；The bottom of bearing block is provided with outside framework oil seal, lower cover, under
Gland closes bearing block and outside framework oil seal, and the top of bearing block is provided with packing ring, filler ring seal bearing, is set at the top of packing ring
There are outside framework oil seal, upper press cover, upper press cover closing packing ring and outside framework oil seal.
The utility model compared with prior art, its protrude the characteristics of be：
The hanger rod component that suspension rod is designed as by flange being coupled by upper and lower two parts, after upper hanger damages, it can pass through
Dismounting ring flange carries out its replacing to it, and repair and maintenance is convenient and swift.Bearing in the bearing block of suspension rod head is taper roller axle
Hold, and in bearing both sides mounting framework oil sealing, effectively alleviate the suspension rod rotatable parts caused by Lack of support, dust enter
Damage.
Further optimal technical scheme is as follows：
Described bearing block center is thick, thin edge, and edge is provided with fixed keyhole, and fixed keyhole, which is connected, expects cup, leads to
Above-mentioned setting is crossed, expects that the connection of cup is more convenient, and connection of the suspension rod with expecting cup is more stable.
The top of described bearing block is provided with sheath, and the bottom of sheath is fastened in above bearing block.
By setting sheath, the sealing of bearing portions is further increased, improves the service life of parts of bearings.On
Stating sheath can design with the sheath integral of suspension rod, can also be designed with the sheath split of suspension rod, then connected by connector
Together.
