Abstract
The utility model relates to a support roll for a rotary hearth furnace, in particular to an improved support roll structure for the rotary hearth furnace. The support roll for the rotary hearth furnace is simple in structure, convenient to produce and process and low in cost. The support roll for the rotary hearth furnace comprises a support base, and a roll body is arranged on the support base via a rotating shaft. The support roll for the rotary hearth furnace is structurally characterized in that a centering flange is arranged at a lateral outer edge of the roll body.
Description
Technical field
The utility model relates to the improvement that a kind of rotary hearth furnace is used supporting roller structure.
Background technology
Rotary hearth furnace starts from rotary heating furnace, through structure of modification, is used for processing and the grandidierite comprehensive utilization of ion dust mud contaning in recent years, produces sponge iron and reclaims non-ferrous metal.
The supporting construction of existing rotary hearth furnace bottom comprises rotation track 7 as shown in Figure 4, is provided with backing roll 11 corresponding to rotation track 7; 11 pairs of rotary hearth furnace sieges 8 of backing roll are only played a supporting role; And sideslip when rotating for fear of rotary hearth furnace siege 8 also need arrange centering track 10 usually in side, rotary hearth furnace siege 8 bottom, also needs to arrange centering roller 9 corresponding to centering track 10.
The rotary hearth furnace lower support structure of this form, member is many, complex structure, production and processing, maintenance and replacing spare part are comparatively loaded down with trivial details, the production cost height.
Summary of the invention
The utility model is exactly at the problems referred to above, provides a kind of simple in structure, and production and processing is convenient, the rotary hearth furnace backing roll that production cost is low.
For realizing above-mentioned purpose of the present utility model, adopt following technical scheme, the utility model comprises base for supporting, is provided with roll body by rotating shaft on the base for supporting, its structural feature roll body side outer rim is provided with the centering rib.
The beneficial effects of the utility model: the utility model has substituted the centering roller in the existing structure and centering track by the centering rib, make the utility model have the centering of rotary hearth furnace simultaneously and support two kinds of functions, simplify the structure significantly, when having reduced production cost, also reduced the expense of processing, maintenance, replacing spare part etc.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is use state diagram of the present utility model.
Fig. 3 is the structural representation of existing rotary hearth furnace backing roll.
Fig. 4 is the use state diagram of existing rotary hearth furnace backing roll.
In the accompanying drawing 1 be base for supporting, 2 for roll body, 3 for rotating shaft, 4 for rolling bearing, 5 for outer roller, 6 for the centering rib, 7 for swing-around trajectory, 8 for the rotary hearth furnace siege, 9 for the centering roller, 10 for centering track, 11 for backing roll.
The specific embodiment
The utility model comprises base for supporting 1, is provided with roll body 2 by rotating shaft 3 on the base for supporting 1, and roll body 2 side outer rims are provided with centering rib 6.
Described roll body 2 comprises the rolling bearing 4 that is arranged at outside the rotating shaft 3, and rolling bearing 4 is outside equipped with the swing-around trajectory 7 contacted outer rollers 5 with rotary hearth furnace siege 8 bottoms; Described centering rib 6 is arranged at a side of outer roller 5.
Rotary hearth furnace siege 8 arranges two swing-around trajectories 7, can along the circumferential direction be provided with two above roll bodies 2 corresponding to each swing-around trajectory 7 according to the size of rotary hearth furnace siege 8; Two swing-around trajectories 7 are inside and outside ring body, and the centering rib 6 on two swing-around trajectories 7 on the corresponding roll body 2 is oppositely arranged.Two centering ribs 6 that are oppositely arranged can better play the centering effect to rotary hearth furnace siege 8.
The height of described centering rib 6 can be 40mm～50mm, and thickness can be 20mm～30mm.
Be understandable that, more than about specific descriptions of the present utility model, only for the utility model being described and being not to be subject to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can make amendment or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as satisfy, all within protection domain of the present utility model.
