The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, (following only describe) shown in Figure 8 with corresponding 19 hole checker brick, blast funnace hot blast stove is with fire grate and leg unit, it comprises pillar 2, crossbeam 3, fire grate 4, deflector 5, the lower surface of crossbeam 3 is shelved on the upper end of pillar 2, the lower surface of fire grate 4 is shelved on the upper end of crossbeam 3, and fire grate 4 is provided with fire grate checkerwork cell 10; Be shelved with deflector 5 on the fire grate 4, deflector 5 is provided with pod apertures; Each pod apertures is made of the little checkerwork cell 8 of three deflectors on deflector 5 tops and the big checkerwork cell 9 of a deflector of deflector 5 bottoms, and three little checkerwork cells 8 of deflector are connected with the big checkerwork cell 9 of deflector respectively; Quantity, size and the position of the little checkerwork cell 8 of deflector on deflector 5 tops are corresponding with quantity, size and the position of the checker brick checkerwork cell 7 of checker brick 6, and the size of the big checkerwork cell 9 of deflector of deflector 5 bottoms is corresponding with the size and the position of the fire grate checkerwork cell 10 of fire grate 4 with the position.
It is smooth parabola shaped that the binding site of described three little checkerwork cells 8 of deflector becomes, and three parabolas are intersected in a bit, and every parabola lower end is a wedge.Be convenient to cut apart air-flow.
Described deflector is a regular hexagon.
The big checkerwork cell of the deflector of 2 pod apertures on the described deflector 59 bottoms are provided with locating hole, and the top of positioning sleeve 12 is positioned at locating hole, and the bottom of positioning sleeve 12 is positioned at the fire grate checkerwork cell 10 of fire grate 4.These two locating holes are provided with positioning sleeve in the place that combines with fire grate, helping deflector accurate location on fire grate, have effectively avoided in the work progress the wrong hole between the checker brick and fire grate to build by laying bricks or stones.
The top of described deflector 5 is provided with groove, and the groove of deflector 5 is corresponding one by one with boss on the checker brick 6.This just realized deflector and checker brick accurate location, be connected, avoid occurring the situation of slippage.
The upper end of described crossbeam 3 is a wedge 11.
The bottom of described pillar 2 is provided with pillar and regulates bolt.By regulating the height of one group of bolt, find the horizontal plane on pillar top accurately; The effect that pillar is regulated bolt is accurately to find the plane accurately, allows all pillar upper surfaces be on the same horizontal plane.After having only all pillar upper surfaces of determining all to be in same plane, just can carry out the construction on next step grouting basis.
The distribution of fire grate checkerwork cell and the bottom of deflector are identical, but fire grate is not located macropore.The function of locating hole mainly relies on positioning sleeve to realize.
Wedge is made in the place that the upper end of crossbeam contacts with fire grate, has both played the effect of effective support, has reduced the contact-making surface with fire grate again to greatest extent.Why design crossbeam, main effect is to avoid fire grate directly to contact with pillar (cylinder).Crossbeam is linear, is that line contacts with fire grate; And pillar is a cylinder, and the top can only be that face contacts with fire grate.Two kinds of forms are compared, and obviously the checkerwork cell area of the line of crossbeam contact shutoff will be much smaller than the face contact of pillar.An other effect of crossbeam is set, and is the force-bearing situation that improves fire grate and pillar, and this point is very important.If crossbeam is not set, the piecemeal of fire grate just must be subjected to the restriction of pillar, carries out the division of fire grate monolithic with the position of pillar, so that the center of gravity of each piece fire grate can drop on the pillar.After being provided with crossbeam, can holding up separated fire grate with crossbeam, and not worry that the center of gravity of monolithic fire grate can pass into others' hands.
The bottom of pillar is provided with pillar and regulates bolt, by regulating the height of one group of bolt, finds the horizontal plane on pillar top accurately; The effect that pillar is regulated bolt is accurately to find the plane accurately, allows all pillar upper surfaces be on the same horizontal plane.
