Description

Изобретение относится к промышленности строительных материалов, а именно к футеровке устройств для охлаждения сыпучих материалов, например цементного клинкера, полученного в обжиговых вращающихся печах. 5The invention relates to the building materials industry, in particular to the lining of devices for cooling bulk materials, such as cement clinker obtained in rotary kilns. 5

Известен холодильник цементного клинкера, содержащий арочную футеровку корпуса и примыкающую к ней вертикальную футеровку шахты [1 ].Known refrigerator cement clinker containing arched lining of the housing and adjacent vertical lining of the mine [1].

Недостатком данного технического ^,0решения является небольШЪй срок службы. Это объясняется тем, что при работе холодильника поступающий из корпуса в шахту запыленный воздух (абразивная клинкерная пыль) быстро разъ- ¹⁵едает арочную и вертикальную футеровки на их стыке (место отклонения потока) .The disadvantage of this technical ^{, 0} solution is its small service life. This is due to the fact that during operation of the refrigerator from flowing into the shaft housing laden air (abrasive clinker dust) rapidly raz- edaet arch ¹⁵ and the vertical liner at their junction (the place of deflection).

Вследствие этого разрушается передняя часть арочной футеровки, тем самым и опирающаяся на нее вертикальная футеровка. Разрушению способствует и то, что при нагреве передняя часть арочной футеровки (свободный конец) от температурного расширения передвигается в сторону шахты, тем сакым воздействует и на лежащую над ней вертикальную футеровку шахты.As a result of this, the front part of the arched lining is destroyed, thereby the vertical lining resting on it. Destruction is also facilitated by the fact that when heated, the front part of the arched lining (free end) from the thermal expansion moves toward the shaft, thereby affecting the vertical shaft lining above it.

Известен узел крепления колосникового холодильника к шахте, содержащий арочную футеровку, примыкающую к ней вертикальную футеровку, узлы подвески футеровок и узел соединения их £2Known is the attachment point of the grate cooler to the shaft, comprising an arched lining, a vertical lining adjacent to it, lining suspension units and a connection unit of £ 2 thereof

Недостатком известного узла крепления является небольшой срок службы по тем же выше изложенным причинам. Наличие узлов подвески, выполненных в виде пластин, не обеспечивает защиту футеровки от истирания и дальнейшего разрушения.A disadvantage of the known mount is a short service life for the same reasons stated above. The presence of suspension nodes made in the form of plates does not protect the lining from abrasion and further destruction.

Цель изобретения - увеличение срока службы.The purpose of the invention is to increase the service life.

Указанная цель достигается тем, что в узле крепления колосникового холодильника к пересыпной шахте, содержащем арочную футеровку корпуса холодильника, вертикальную футеровкуThis goal is achieved by the fact that in the attachment point of the grate refrigerator to the overflow shaft containing an arched lining of the refrigerator body, a vertical lining

1004730 4 ностью арочной футеровки 1 в виде козырька, препятствуют истиранию футеровки на участке отклонения запыленного воздуха, поступающего из полости корпуса 1 холодильника в полость шахты 4. Кроме этого, консоль 7 прикрывает корпус 1 на участке зазора между торцовой поверхностью футеровки 1 и стойки 5»1004730 4 with an arch lining 1 in the form of a visor, they prevent abrasion of the lining in the area of deviation of dusty air coming from the cavity of the body 1 of the refrigerator into the cavity of the shaft 4. In addition, the console 7 covers the body 1 in the area of the gap between the end surface of the lining 1 and the rack 5 "

Предложенное устройство способствует продлению срока службы футеровки колосникового холодильника, тем самым и корпуса, что дает экономию огнеупорных кирпичей и металла. Снижаются потери тепла от корпуса, что способствует повышению температуры вторичного воздуха, поступающего из холодильника в печь (экономия топлива).The proposed device helps to extend the life of the lining of the grate cooler, and thereby the housing, which saves refractory bricks and metal. Heat losses from the housing are reduced, which contributes to an increase in the temperature of the secondary air coming from the refrigerator to the furnace (fuel economy).

Claims

The invention relates to the building materials industry, namely to the lining of devices for cooling bulk materials, such as cement clinker, obtained in kiln rotary walls. A cement clinker refrigerator is known that contains an arched hull lining and an adjacent shaft lining l. The disadvantage of this technical solution is the non-uniform service life. This is due to the fact that during the operation of the refrigerator, the dusty air (abrasive clinker dust) coming from the housing into the shaft quickly corrodes the arched and vertical linings at their junction (the place of flow deflection). As a result, the front part of the arched linings is destroyed, thereby with a vertical lining on it. The destruction is also promoted by the fact that when the front part of the arched lining (free end) is heated, the thermal expansion moves towards the shaft, the sakshm also affects the vertical lining of the shaft above it. . The known grate attachment unit of the grate cooler to the mine contains an arched lining, a vertical lining adjacent to it, lining hanger assemblies and their C2 connection unit. A disadvantage of the known fastening assembly is a short service life for the same reasons stated above. The presence of the suspension assemblies made in the form of plates does not protect the lining against abrasion and further destruction. The purpose of the invention is to increase the service life. This goal is achieved by the fact that in the node of fastening the grate cooler to the pouring mine containing the arched lining of the refrigerator body, the vertical lining of the shaft and the junction of the lining, the latter is made in the form of an arc profile with vertical supports and horizontal consoles, which are arched and the vertical of the liners, and the vertical stand, is installed at the junction of the linings with a gap in relation to the arched lining. FIG. 1 shows the fixing unit of the grate cooler to the pouring mine, general view; FIG. 2 is a view A of FIG. 1, the mount comprises an arched lining 1 of the body 2 and a vertical lining 3 of the shafts. At the junction of linings 1 and 3 there is an assembly for connecting them, made in the form of an arc profile with a vertical stand 5 attached to the shaft, and the two lower cantilevers 6 and 7. The arc of the heat-resistant steel can be made whole or from separate segments . The mount 5 with respect to the end wall of the arch lining 1 is installed with a gap. The console 6 faces the cavity cavity and is located under the base of the vertical lining 3, and the console 7 is located under the inner surface of the arch lining 1 of the housing 2 in the form of a visor. The vertical lining 3 of the shaft k is separated from the arch lining 1 and rests on the cantilever 6, thus does not depend on the heating and lengthening of the front part of the arch lining 1. The installation of the pillar 5 with a gap in relation to the end honor of the arch lining ki 1 creates conditions for the expansion arch lining 1 and elongation in the direction of the cavity of the mine k without destruction of the lining. The console 6, located under the base of the vertical lining 3 and the console 7, located under the inner surface of the arch lining 1 in the form of a visor, prevents abrasion of the lining at the deflection site of the dusty air coming from the cavity of the refrigerator body 1 into the cavity of the shaft k. In addition, the "console 7 covers the case 1 at the gap between the end surface of the lining 1 and the stand 5o. The proposed device extends the service life of the lining of the grate cooler, and thus the body, which saves refractory bricks and metal. The heat loss from the body is reduced, which contributes increasing the temperature of the secondary air coming from the refrigerator to the furnace (fuel economy). Claims The grate attachment unit of the grate cooler to the pouring mine contains an arched lining of the refrigerator body, a vertical shaft lining and a lining connection unit, characterized in that, in order to increase the service life, the connection unit is made in the form of an arc profile with a vertical stand and horizontal consoles, on which the arched and vertical linings are supported, and the vertical stand is installed at the junction of linings with a gap in relation to the arched linings.
