Embodiment Construction

[0020] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0021] The arch at the exit of the CDQ chamber needs to be pre-processed and pre-assembled before delivery. The arch at the exit of the CDQ chamber is located on the outer wall of the CDQ furnace and is in the shape of an arch bridge. It must conform to the arc of the outer wall of the CDQ oven. , but also to meet the arc span of the annular air duct gas flow to the primary dust collector. The arch at the exit of the CDQ chamber consists of upper and lower layers. The first layer is composed of mullite bricks, and the second layer is a layer of staggered bricks connecting the large wall.

[0022] Such as figure 1 and figure 2 as shown,

[0023] Prepare a platfor...

Abstract

The invention relates to an arch pre-assembly processing method, and especially relates to a pre-assembly processing method for a dry quenching chamber outlet arch used in a coke dry quenching process. Presently, a wood die is used in the pre-assembling process of the outlet arch. The two ends of the wood die is required to be fixed by using fixing tools, such that a masonry structure is prevented from slipping towards the two ends. The weight of a single brick used in the upper masonry structure is large, and a tool stand is required to be built. A total weight of the arch is approximately 18 tons. Therefore, the wood die is required to have certain strength. The cost is high, the method is complicated, and the dimensions can not be finely controlled. According to the invention, on a platform regulated to a horizontal position, an arc-shaped inner curve and an arc-shaped outer curve of the outlet arch are drawn. A first brick layer which is a mullite brick layer is arranged between the inner curve and the outer curve. Paper splints are arranged between the bricks. When arranging is finished, the surface of the bricks is smoothed by an angle grinder. A second staggered brick layeris placed on the platform, and is firmly combined with the mullite brick layer. Therefore, a requirement is satisfied, that the staggered brick layer and the mullite brick layer are jointed and staggered.

Description

technical field [0001] The invention relates to a method for pre-assembling an arch, in particular to a method for pre-assembling an arch at the outlet of a dry quenching chamber. Background technique [0002] The arch of the exit of the CDQ CDQ chamber is located on the CDQ outer wall of the CDQ furnace. It is in the shape of an arch bridge. span. The whole consists of upper and lower floors, the first floor is made of mullite bricks, and the second floor is a layer of staggered bricks connecting the large wall. At present, the wooden molds used in the pre-assembly of the entire exit arch need to be fixed with fixed tools at both ends to prevent the masonry from slipping to both ends. The total weight is about 18 tons, and the wooden mold is required to have a certain strength, the cost is high, the method is complicated, and the size cannot be carefully controlled. Contents of the invention [0003] The object of the present invention is to provide a method for pre-as...
