Abstract
The utility model discloses a novel grate for a hot blast stove. The novel grate is composed of a grate plate and a grate cover plate, wherein the grate cover plate is mounted on the grate plate. Hexagonal grate plate holes are uniformly arranged on the grate plate; the connection part between holes forms a hole wall supporting the grate cover plate; and a grate cover plate is correspondingly arranged in each grate plate hole. The grate cover plate mainly comprises an upper support plate, a reinforcing rib, a lower support plate and a hexagonal prism cylinder, wherein the lower support plate is a hexagon placed on the hole wall to fix the grate cover plate. The hexagonal prism cylinder is inserted into the grate plate hole to connect the grate plate with the grate cover plate. The hexagonal prism cylinder is also provided with a channel. According to the utility model, a combined structure is adopted, and the manufacturing is convenient. The manufacturing and mounting method of the conventional grate for a hot blast stove is changed, the damage frequency of checker bricks is reduced, and the service life is prolonged. The metal components are movably mounted, the construction is convenient, the labor intensity of workers is reduced, and the construction efficiency is improved.
Description
Technical field
The utility model relates to the accessory of ironmaking with blast furnace, relates in particular to a kind of novel hotblast stove and uses fire grate.
Background technology
Hotblast stove is the member that is used for supporting the top heat storage with fire grate.Usually adopt and divide body structure, checker brick work is put on the fire grate.This method is prone to cause the checker brick hole to be difficult to aim at phenomenon with hole on the fire grate, causes the through-hole rate of checker brick to descend.In addition; The thermal expansivity of fire grate and the thermal expansivity of checker brick differ bigger; Receive the souring of high temperature gas flow to cause slippage between checker brick and fire grate, and the load-bearing above the checker brick plays the effect of reverse obstruction power, cause with the checker brick crackle of fire grate contact position or squeeze broken.
The utility model content
In view of this, the utility model technical problem to be solved provides a kind of employing combined structure to above deficiency exactly, has long service life, easily manufactured, low cost of manufacture, and the novel hotblast stove of characteristics such as construction install convenience is used fire grate.
A kind of novel hotblast stove is used fire grate, is made up of grate plate, fire grate cover plate, and wherein, the fire grate cover plate is installed on the grate plate.
Evenly offer hexagonal fire grate plate hole on the grate plate, the connection portion between the Kong Yukong forms hole wall, works to support the fire grate cover plate fire grate cover plate of corresponding placement in each fire grate plate hole.
The fire grate cover plate mainly is made up of the prismatic tube of mounting plate, stiffening web, bolster and hexagon, and the mounting plate profile is a Π shape, and through hole is hexagon or circle on it.
Bolster is a hexagon, is placed on the hole wall, plays the effect of stationary furnace grate cover plate.
The prismatic tube of hexagon inserts in the fire grate plate hole, to connect grate plate and fire grate cover plate.
Also be provided with passage on the prismatic tube of hexagon.
The beneficial effect that the technical scheme of the utility model reaches is:
1
,The utility model adopts integrated structure, and is easily manufactured, can be prefabricated in advance.
2, the utility model has changed making and the installation method of traditional hotblast stove with fire grate, has reduced the damage number of times of checker brick, has prolonged its work-ing life.
3, be movable the installation between the utility model hardware, easy construction has reduced working strength of workers, has improved operating efficiency.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is done further explanation:
Fig. 1 is the grate plate structural representation of the utility model.
Fig. 2 is the fire grate covering plate structure synoptic diagram of the utility model.
Fig. 3 is the A-A sectional view among Fig. 2.
Fig. 4 is the B-B sectional view among Fig. 2.
Fig. 5 is the C-C sectional view among Fig. 2.
Fig. 6 is the user mode figure of the utility model.
Embodiment:
Can find out that by Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6 this novel hotblast stove is used fire grate, mainly form by matter fire grate 1, the casting of fire grate cover plate; Look the size of hotblast stove internal diameter, confirm the shape and the number of its block diagram, wherein; The fire grate cover plate is arranged on the fire grate 1, evenly is provided with fire grate plate hole 2 on the fire grate 1, and the connection portion between the Kong Yukong forms Kong Bi; Play a part to support the fire grate cover plate, place a fire grate cover plate in each fire grate plate hole 2.
It can also be seen that by Fig. 2, Fig. 3, Fig. 4 and Fig. 5 the fire grate cover plate mainly is made up of the prismatic tube 7 of mounting plate 3, stiffening web 5, bolster 6 and hexagon, mounting plate 3 profiles are Π shape, and through hole is hexagon or circle on it.With integral casts by drawing such as the prismatic tubes 7 of mounting plate 3, stiffening web 5, bolster 6 and hexagon, select cast iron or cast steel for use.The prismatic tube of hexagon 7 internal diameters are less than fire grate plate hole 2 footpaths 3～5mm, as the expansion clearance; On the prismatic tube 7 of hexagon, have passage 4, each hole in the mounting plate 3 can both be communicated with the prismatic tube 7 of hexagon.Stiffening web 5 is the M type.
The fire grate that casting is good is placed on the bracing frame of furnace bottom by hotblast stove furnace bottom shape successively, will cast good fire grate cover plate then and insert respectively in the fire grate plate hole 2.
