Description

(54) ХОЛОДИЛЬНИК ШАХТНОЙ ПЕЧИ(54) MINER REFRIGERATOR

1one

Изобретение относитс  к черной метал лургии, в частности к устройствам дл  охлаждени  доменных печей.The invention relates to ferrous metallurgy, in particular to devices for cooling blast furnaces.

Наиболее близким к описываемому изобретению по технической сущности и достигаемому результату  вл етс  пЛитовый холодильник ОЛЯ доменных печей, состо щий из корпуса с залитыми в нем трубками, по которым а11ркулирует вода, и крепежных (деталей. Дл  повышени  герметичности сты ков между хойодильникамн корпус холодильника снабжен плоскими металлическими ребрами , ; расположенными ло углам вертикалных и горизонтальных стенок The closest to the described invention in terms of technical essence and the achieved result is a PLA cooler OLA blast furnaces, consisting of a casing with tubes filled with water along which water is supplied, and fasteners (parts. To increase the tightness of the joints between the refrigerator, the casing of the refrigerator metal ribs, located at the corners of the vertical and horizontal walls

Недостатком известного холодильника  вл етс  растрескивание металлической плиты иэ-за возникающих в ней термича- скнх напр жений, что приводит к выходу из стро  всего холодильника.A disadvantage of the known refrigerator is the cracking of the metal plate and because of the thermal stresses arising in it, which leads to the failure of the entire refrigerator.

Цель изобретени  - компенсаци  термических напр жений и повышение стойкости холодильника. Это достигаетс  тем, что меааллическа  плита выполнена из отдельных брусьев, закрепленных с зазором между собой на охлаждающих трубах пластинчатыми пружинами, а охлаждающие трубы снабжены шпильками, которые креп тс  на кожухе печи.The purpose of the invention is to compensate for thermal stresses and increase the durability of the refrigerator. This is achieved by the fact that the metal plate is made of separate bars, fastened with a gap between them on the cooling pipes by plate springs, and the cooling pipes are provided with studs that are attached to the furnace casing.

На фиг. 1 показан описываемый холодильник; на фиг. 2 - то же, разрез по А-А на фиг. I (крепление автономных брусьев к охлаждающим их трубам); на фиг. 3 - то же, поперечных -разрез по Б на фиг. 1.FIG. 1 shows the described refrigerator; in fig. 2 is the same; the section along A-A in FIG. I (mounting autonomous bars to their cooling pipes); in fig. 3 - the same, the transverse section of B in FIG. one.

Холодильник состоит из автономных брусьев 1, образующих металлическую плиту; пластинчатых пружин 2, шпилек 3, с помощью которых автономные фусь  закреплены на охлаждающих трубах 4, и шпилек 5, креп щих охлаждающие трубы к кожуху 6 печи.The refrigerator consists of autonomous bars 1, forming a metal plate; lamellar springs 2, studs 3, with which autonomous fus are fixed on cooling pipes 4, and studs 5 securing the cooling pipes to the casing 6 of the furnace.

При нагреве происходит расширение брусьев 1, которые за счет зазоров между ними могут смещатьс  относительно поверхности охлаждающих их труб 4, Образующеес  в процессе работы холодильника термическое удлинение шпилек 3, при помонш которых плиты прижимаютс  к трубам 4, компенсируетс  за счет предварительной деформации пластинчатых пружин 2. При этом обеспечиваетс  оостаточное прижатие автономных брусьев к поверхности охлажпаюших труб. Таким образом, описываемый холоцильни металлургической шахтной печн Ноэвол ет Хмвкьшить возможность разрушени  плит от термических напр жений в них и искл1о разрушение охлажоаюших труб. Формула иаобретенн Холодильник шахтной печи, со ержащк метадлическую плиту с ребрами, озшаждато ише трубы и крепежные детали, о т л ичающийс  тем, что, с целью компенсации термических напр жений и повышени  его стойкости, металлическа  плита выполнена из отдельных брусьев, закрепленных с заасфами между собой на охлаждаюШйх трубах упругими планками, а крепежные детали - в виде шпилек, закрепленных на охлаждающих трубах н кожухе печи. Источники информадии, прин тые во внимание ори экспертизе: I, Автсчэское свидетельство) 41ОО92, кл. С 21В 7/10, 21.12.71.When heated, the bars 1 expand, which due to gaps between them can shift relative to the surface of their cooling pipes 4. The thermal elongation of the studs 3 formed during the operation of the refrigerator, during which the plates are pressed against the pipes 4, is compensated by pre-deformation of the leaf spring 2. At the same time, the autonomous bars are still pressed to the surface of the cooled pipes. Thus, the described holocyl metal of the metallurgical shaft furnace Noevolm hmvshit possibility of the destruction of plates from thermal stresses in them and the destruction of the cooling pipes. Formula invented The shaft kiln refrigerator, containing a metadlice plate with fins, has formed pipes and fasteners, which is due to the fact that, in order to compensate for thermal stresses and increase its durability, the metal plate is made of separate bars fixed with sausages between on the cooling pipes with elastic strips, and fasteners in the form of studs attached to the cooling pipes and the furnace casing.
