Abstract
The utility model is a boiler arch structure utilizing chute grate. The width of the grate can be increased according to the demands of users without affecting the boiler top. The utility model comprises a boiler arch body which comprises a front arch and a rear arch, which is characterized in that the arch tops of the front arch and the rear arch are respectively flat tops, and two support pipes are respectively arranged in the front arch and the rear arch.
Description
(1) technical field
The utility model relates to the endless grate technical field, is specially a kind of furnace arch structure that adopts the boiler of endless grate fire grate.
(2) background technology
Along with social development, jumbo boiler demand is improved.And the capacity of boiler strengthens, and the width of corresponding boiler grate also will increase, and vault is generally circular arc, see Fig. 1, the width B of chimney arch also will strengthen accordingly like this, and the arch capacity H of corresponding vault also must strengthen thereupon, and arch capacity H is big more, and boiler is easy more to collapse.
(3) summary of the invention
At the weak point of existing furnace arch structure, the utility model provides another furnace arch structure that adopts the boiler of endless grate fire grate, and the width of its fire grate can strengthen according to user's demand, and furnace roof can not be affected.
Its technical scheme is such: it comprises the chimney arch body, and described chimney arch body comprises face arch, rear arch, it is characterized in that: the vault of described face arch, rear arch is respectively flat-top, is respectively arranged with stay pipe in described face arch, rear arch.
It is further characterized in that: described stay pipe is horizontally disposed along the width of described face arch, rear arch respectively, and described stay pipe is respectively cooling tube, passes to cooling medium in the described cooling tube, and described cooling medium is an air; Described cooling medium is a water, and described cooling medium is the fuel of boiler heating usefulness itself; Arranged in series or be arranged in parallel between the described cooling tube.
The utility model adopts after the said structure, cooling tube can play the effect of support, prevent that furnace roof from collapsing, and the medium in the cooling tube can in time cool off furnace roof, further prevent collapsing of furnace roof, thereby avoided existing structure that the circular arc vault is adopted on the chimney arch top, the arch capacity strengthens, the shortcoming that boiler easily collapses.

Fig. 1 is the structural representation of existing boiler circular arc chimney arch;
Fig. 2 is the structural representation of the utility model and fire grate;
Fig. 3 is that the A-A of face arch among Fig. 2 is to view;
Fig. 4 is that the B-B of rear arch among Fig. 2 is to view;
Fig. 5 is the structural representation of cooling tube in face arch or the rear arch.
(5) specific embodiment
See Fig. 2, the utility model comprises the chimney arch body, the chimney arch body comprises face arch 2, rear arch 4, the vault of face arch 2, rear arch 4 is respectively flat-top (seeing Fig. 2, Fig. 3, Fig. 4), be respectively arranged with stay pipe 3,5 in face arch 2, rear arch 4, along the horizontally disposed (see figure 5) of width of face arch 2, rear arch 4, stay pipe 3,5 is respectively cooling tube to stay pipe 3,5 respectively, pass to cooling medium in it, this cooling medium can or be the fuel of boiler heating usefulness itself for air, water; Cooling tube is formed by connecting by straight tube 7 and elbow 8, and cooling tube can arranged in series or is arranged in parallel, and 6 is fire grate.The function that cooling tube has cooling concurrently and supports, the degree that face arch, rear arch expand with heat and contract with cold is lighter, has guaranteed that face arch 2, rear arch 4 are difficult for collapsing.
Claims (7)
1, a kind of furnace arch structure that adopts the boiler of endless grate fire grate, it comprises the chimney arch body, described chimney arch body comprises face arch, rear arch, it is characterized in that: the vault of described face arch, rear arch is respectively flat-top, is respectively arranged with stay pipe in described face arch, rear arch.
2, according to the described a kind of furnace arch structure that adopts the boiler of endless grate fire grate of claim 1, it is characterized in that: described stay pipe is horizontally disposed along the width of described face arch, rear arch respectively.
