Description
Technical Field
The utility model belongs to the field of mechanical equipment, and particularly relates to a box beam for a receiving port of a ring cooling machine.
Background
At present, a circular cooler in a chain grate-rotary kiln pelletizing process at home and abroad is annular cooling equipment and is used for cooling pellets roasted by a rotary kiln, and high-temperature pellets are cooled to normal temperature after being cooled by the rotary operation of a trolley of the circular cooler. The feeding port is used for uniformly distributing hot pellet ores onto the trolley, the periphery of the bottom of the feeding port of the circular cooler is of a box-shaped beam structure, the material is 1Cr18Ni9 Ti, the size is 1700 x 500 x 230mm, and the box-shaped beam plays a role in protecting the bottom plate of the feeding port from burning loss and insulating heat. In the production process, as the box beam is in direct contact with the high-temperature pellets, the upper part, the rib plates and the bottom part of the box beam are frequently seriously burnt, and after the upper part is burnt, the refractory bricks on the upper part of the box beam fall off in a large area; after the bottom plate and the rib plate are burnt, the strength of the box beam is reduced and the box beam is deformed, so that the refractory material falls off; if the lower supporting plate is burnt and deformed, the rotary body fence plate bricks can be scraped, so that equipment is damaged in a wider range until production is stopped. Through multiple accident analysis, the box beam restricts the stable operation of the circular cooler, and the box beam needs to be redesigned
The box beam at the bottom of the receiving port of the original circular cooler mainly comprises the following parts: bottom plate, upper bracket board, backup pad, the main problem who exists: firstly, the material has the problems of insufficient heat-resistant temperature and serious burning loss; secondly, the structure is unreasonable, and the strength is not enough and the deformation is serious after burning. The service life of the box beam is only about 90 days due to the problems, the box beam needs to be checked once every 45 days, and the influence on normal pellet production is large. Therefore, improvements are needed.
Disclosure of Invention
The utility model aims to provide a box-shaped beam for a receiving port of a circular cooler, which can improve the operation period and the equipment operation rate of the circular cooler, improve the operation efficiency of a grate-rotary kiln-circular cooler pellet production line and reduce the production cost.
The purpose of the utility model is realized by the following technical scheme:
the box beam for the receiving port of the ring cooling machine is characterized by comprising a supporting plate, a vertical plate vertically connected with the supporting plate, a rib plate for connecting the vertical plate and the supporting plate, and a socket arranged on the vertical plate, wherein the end part of the supporting plate extends downwards at an angle of 90 degrees with the supporting plate.
The downward extending part of the end part of the supporting plate is 78-82 mm.
The vertical plate, the rib plate and the supporting plate are made of heat-resistant steel and are formed by one-step casting.
The utility model has the advantages that:
compared with the prior art, the box beam for the receiving port of the ring cooling machine has the advantages that the original box beam structure is modified into the supporting plate type structure, the end part of the supporting plate type structure extends downwards by 80mm, and meanwhile, the original material 1Cr18Ni9 Ti is changed into heat-resistant cast steel, so that the problem of burning loss of the box beam is solved, and the service life of the material feeding port is prolonged.

Detailed Description
The following further describes the embodiments of the present invention with reference to the drawings.
As shown in fig. 1 and 2, the box beam for the receiving port of the ring cooling machine is characterized by comprising a supporting plate 3, a vertical plate 1 vertically connected with the supporting plate 3, a rib plate 2 connecting the vertical plate 1 and the supporting plate 3, and a socket 4 arranged on the vertical plate 1, wherein the end part of the supporting plate 3 extends downwards at an angle of 90 degrees with the supporting plate.
The downward extending part of the end part of the supporting plate 3 is 78mm-82 mm.
The vertical plate 1, the rib plate 2 and the supporting plate 3 are made of heat-resistant steel and are formed by one-step casting.
The utility model relates to a box beam for a receiving port of a ring cooling machine, which consists of four parts, namely a vertical plate 1, a rib plate 2, a supporting plate 3 and a socket 4. The novel box-shaped beam is manufactured by casting heat-resistant steel at one time, the heat-resistant steel resists high temperature of about 1600 ℃, and the heat-resistant temperature of the white steel 1Cr18Ni9 Ti is 850 ℃, so that the burning loss and cracking phenomena of the prior white steel structural member are avoided. The box girder structure modification changes the box girder structure into a supporting plate structure, and the end part extends downwards by 80mm, the first strength of the novel box girder can be greatly improved by the structural form, the deformation of the girder body is avoided, and the second direct baking of the pellet ore to the intermediate plate of the circular cooler can be resisted. The wear-resistant bricks are built on the supporting plate 3, so that the problem of scraping and clamping the revolving body fence bricks by the deformation of the lower supporting plate of the original box-shaped beam can be solved, and the overhaul period of the feed opening can be prolonged.
The method comprises the following specific operations:
1. and manufacturing three lifting lugs according to the size of the novel box-shaped beam socket.
2. Three lifting lugs are welded on a lateral plate of a feed port of the circular cooler according to the distance of the beam insertion port 4.
3. And hanging the cast box-shaped beam on a lifting lug on the feed port side plate.
4. And (3) inserting a white steel bolt into the lifting lug at the socket 4 of the box beam, fixing the box beam on the feeding port side plate, and then building and casting wear-resistant bricks on the box beam supporting plate.
Compared with the prior art, the box beam for the receiving port of the ring cooling machine has the advantages that the original box beam structure is modified into the supporting plate type structure, the end part of the supporting plate type structure extends downwards by 80mm, and meanwhile, the original material 1Cr18Ni9 Ti is changed into heat-resistant cast steel, so that the problem of burning loss of the box beam is solved, and the service life of the material feeding port is prolonged.
