Abstract
The utility model discloses an upper rippling fence of a trolley of a sintering machine. The upper ripping fence comprises a first ripping fence and a second ripping fence which are arranged side by side, side faces, facing towards each other, of the first ripping fence and the second ripping fence are a connecting face of the first ripping fence and a connecting face of the second ripping fence respectively, the connecting face of the first ripping fence is provided with a concave portion, the connecting face of the second ripping fence is provided with a protruding portion, and the concave portion is matched with the protruding portion to form a mortise and tenon joint structure. Shapes of the connecting faces of the first ripping fence and the second ripping fence which form the upper ripping fence of the trolley of the sintering machine are changed, the connecting face of the first ripping fence and the connecting face of the second ripping fence are connected together in a lapped mode, sealing effects are greatly improved compared with that of two parallel connecting faces at present, therefore, the phenomenon of air leakage of the trolley of the sintering machine is reduced, and not only is energy consumption reduced, but also the yield and quality of sintering ore are improved.
Description
Technical field
The utility model relates to the sintering pallet in metallurgical machinery sector, is specifically related to the upper breast board of sintering pallet.
Background technology
Sintering, is that granular material is changed into DB, is a traditional technical process.In general, powder is after overmolding, and the DB obtaining by sintering is a kind of polycrystalline material, and its microstructure is comprised of crystal, vitreum and pore.Sintering process directly affects crystallite dimension, pore size and grain-boundary shape and the distribution in microstructure.Before blast furnace ironmaking is produced, by various powdery iron-containing raw materials, allocate appropriate fuel and flux into, add appropriate water, after mixing and pelletizing, on agglomerating plant, make material generation series of physical, chemical change, sinter the process of piece into, on producing, extensively adopt the cooling sintering deposit of rotary forced-air cooler.
In prior art, sintering pallet mainly comprises car body 10, be located at the wheel assembly 11 of car body 10 bottoms, be arranged on the grid section 12 in length over ends of body direction, car body 10 length direction one end are provided with lower breast board 14, at the top of lower breast board 14, be provided with breast board 13, go up breast board 13 and lower breast board 14 is arranged above and below, wherein going up breast board 13 is normally comprised of the first and second two breast boards, the first and second two breast boards are arranged side by side and are bolted to connection, because the joint face of the first and second two breast boards is plane, therefore, after two breast boards connect, between joint face, conventionally all there is the vertical gap of 3～5mm left and right, sealing effectiveness is undesirable, there is the situation of leaking out, and leaking out of sintering pallet not only can increase energy consumption, and meeting affect output and the quality of sintering deposit greatly.
Utility model content
For above shortcomings in prior art, the purpose of this utility model is that the upper breast board of existing sintering pallet is transformed, and improves the sealing of sintering pallet, reduces and leaks out as much as possible.
To achieve these goals, the utility model has adopted following technical scheme: the upper breast board of sintering pallet, comprise the first breast board and the second breast board that are arranged side by side, the side that described the first breast board is relative with the second breast board is respectively the joint face of the first breast board and the joint face of the second breast board, it is characterized in that: the joint face of described the first breast board has depressed part, the joint face of described the second breast board has protuberance, the described depressed part formation joinery and its construction that matches with protuberance.
As the optimization of technique scheme, the cross section of described depressed part and protuberance is rectangle.
As further optimization, the length of described depressed part is 18 ~ 20mm, and the length of described protuberance is 16 ~ 17mm.
The beneficial effects of the utility model are: the utility model is by changing forming first breast board of upper breast board of sintering pallet and the shape of the joint face of the second breast board, the joint face of the first breast board and the joint face of the second breast board are linked together in the mode of overlap joint, compare existing as two joint faces that are parallel to each other, sealing effectiveness has obtained larger improvement, thereby reduced the air leakage phenomena of sintering pallet, not only lower energy consumption, and improved output and the quality of sintering deposit.

In figure, car body 10, wheel assembly 11, grid section 12, upper breast board 13, lower breast board 14, the first breast board 15, depressed part 16, the second breast board 17, protuberance 18.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
embodiment:as shown in Figures 2 to 6, the upper breast board of sintering pallet, comprise the first breast board 15 and the second breast board 17 that are arranged side by side, the side that the first breast board is relative with the second breast board is respectively the joint face of the first breast board and the joint face of the second breast board, the joint face of the first breast board has depressed part 16, the joint face of the second breast board has protuberance 18, the depressed part 16 formation joinery and its construction that matches with protuberance 18.Depressed part 16 is the fourth of the twelve Earthly Branches, or mortise or tongue-and-groove, and protuberance 18 is tenon or tenon.For the ease of processing, the cross section of depressed part 16 and protuberance 18 is preferably rectangle, and wherein the long limit when depressed part 16 is 18 ~ 20mm, when the long limit of protuberance 18 is 16 ~ 17mm, depressed part 16 is firm with the joinery and its construction that protuberance 18 forms, and sealing effectiveness is better.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
