Abstract
The utility model discloses ventilation crossbeam in a kind of circular machine bellows, the mounted head 2 of taking by arc beam body 1 and arc beam body 1 end constitutes, the mounted head 2 of taking of arc beam body 1 and arc beam body 1 end is ductile cast iron casting, and one-step casting is an integral body, the outer edge of arc beam body 1 is inclined-plane 3, is arranged with vertical through hole 4 at arc beam body 1 upper edge center line.Ventilation crossbeam in these circular machine bellows, can not only support the weight of furnace grid and raw materials for sintering, and wind can pass from the through hole of arc crossbeam, improve draught area, air quantity is distributed be tending towards evenly, and then improved the quality of sintering velocity, output and the sintering deposit of sintering machine; Simultaneously because improved the bellows draught area, relative minimizing air leak rate of air curtain, thereby given full play to the usefulness of blower fan, reduced power consumption, can be widely used in circular machine.
Description
Technical field
The utility model relates to the improvement of supporting the crossbeam of fire grate bar in a kind of circular machine bellows, particularly a kind ofly can make ventilation crossbeam in the circular machine bellows that ventilate in the middle of the crossbeam, is applicable to the circular machine of various different sizes.
Background technology
After igniting, raw materials for sintering on the circular machine fire grate bar reaches the purpose of sintering by ventilation.Raw materials for sintering cloth is provided with two arc crossbeams bellows suitable for reading on the fire grate bar of each bellows, the one or both ends of fire grate bar ride on the arc crossbeam, and the arc crossbeam is supporting fire grate bar, is also supporting raw materials for sintering.Because of being covered by the end of fire grate bar above the arc crossbeam, wind can only pass through from the slit between the adjacent fire grate bar, and the air quantity that passes through is big more, even more, then helps improving the quality and the output of sintering deposit more.The arc crossbeam that uses is a metal solid at present, and broad, and proportion is bigger in whole bellows area, thereby has reduced the draught area in the bellows; Simultaneously, because the arc crossbeam is a metal solid, the dust stratification between the fire grate bar on the arc crossbeam is difficult to remove, and has formed a stuffy zone, and has caused the skewness of air quantity, so influenced the quality of sintering velocity, output and the sintering deposit of sintering machine.
Summary of the invention
The purpose of this utility model is to provide a kind of weight that can support fire grate bar and raw materials for sintering, can improve draught area again, make the air quantity distribution be tending towards the interior ventilation crossbeam of circular machine bellows of sintering velocity, output and the sinter quality of even and then raising sintering machine.
For reaching above purpose, the technical scheme that the utility model adopted is: ventilation crossbeam in these circular machine bellows, the mounted head of taking by arc beam body and arc beam end of body constitutes, the mounted head of taking of arc beam body and arc beam end of body is a ductile cast iron casting, and one-step casting is an integral body, the outer edge of arc beam body is the inclined-plane, be beneficial to ventilate, it is characterized in that being arranged with vertical through hole at arc beam body upper edge center line, wind can directly pass in through hole, increasing draught area, improve the Uniform Ventilation degree in the bellows, also can make dust stratification in the slit of fire grate bar end, arc beam body top from through hole declines bellows simultaneously by manually beaing fire grate bar.The utility model is also implemented by following measure: described through hole is a rectangular through holes, and the inside edge of through hole also is the inclined-plane, but one-shot forming in the casting process of arc beam body; The crooked radian of described arc beam body is consistent with the radian of installation site on circular machine.When using the utility model, arc beam body taken be contained on the setting up the stage of bellows inwall suitable for reading, can install two side by side, again fire grate bar is installed between the arc beam body and and the bellows wall of both sides between, when fire grate bar is installed, make between the fire grate bar joint of arc beam body top and leave certain clearance, simultaneously, also to make between the adjacent fire grate bar and leave certain clearance, like this, wind is passed from through hole, and on the arc cross girder and the dust stratification between the adjacent fire grate bar joint also can fall by vibration.
The beneficial effects of the utility model are: compare with the arc crossbeam that present circular machine uses, can not only support the weight of fire grate bar and raw materials for sintering, and wind can pass from the through hole of arc crossbeam, improved draught area, air quantity is distributed be tending towards evenly, and then improved the quality of sintering velocity, output and the sintering deposit of sintering machine; Simultaneously because improved the bellows draught area, relative minimizing air leak rate of air curtain, thereby given full play to the usefulness of blower fan, reduced power consumption.

The specific embodiment
Make the utility model with reference to accompanying drawing 1,2,3.Ventilation crossbeam in these circular machine bellows, the mounted head 2 of taking by arc beam body 1 and arc beam body 1 end constitutes, the mounted head 2 of taking of arc beam body 1 and arc beam body 1 end is ductile cast iron casting, and one-step casting is an integral body, the outer edge of arc beam body 1 is inclined-plane 3, is arranged with vertical through hole 4 at arc beam body 1 upper edge center line.Described through hole 4 is a rectangular through holes, the inside edge of through hole 4 also be inclined-plane 3 ', but one-shot forming in the casting process of arc beam body 1; The crooked radian of described arc beam body 1 is consistent with the radian of installation site on circular machine.Fig. 4 has provided the installment state schematic top plan view, and Fig. 5 has provided application state vertical cross section cross-sectional schematic.Arc beam body 1 is taken and is contained on bellows 5 suitable for reading, and side by side establish two, an end of fire grate bar 6 or two ends are taken and are contained on the arc crossbeam 1, leave gap 7 between the joint of the fire grate bar 6 on the arc beam body 1, also leave certain interval 8 between the adjacent fire grate bar 6.
Claims (2)
1, ventilation crossbeam in a kind of circular machine bellows, lap joint (2) by arc beam body (1) and arc beam body (1) end constitutes, the lap joint (2) of arc beam body (1) and arc beam body (1) end is a ductile cast iron casting, and one-step casting is an integral body, the outer edge of arc beam body (1) is inclined-plane (3), it is characterized in that being arranged with vertical through hole (4) at arc beam body (1) upper edge center line.
