Combined assembling structure of stainless steel surface aluminium silicate composite board

Abstract

The invention discloses a combined assembling structure of a stainless steel surface aluminium silicate composite board, and relates to the technical field of the casing pipe plugging of a current conversion station variable flowing deformation valve side. The combined assembling structure is laterally assembled between stainless steel surface aluminium silicate composite boards, an assembled seamis tightly filled through an aluminium silicate fiber blanket and a magnesium fire-proof board, and assembling is fixed through a bayonet structure. A variable flowing deformation casing pipe installation hole is formed in a way that a plurality of stainless steel surface aluminium silicate composite boards are provided with openings and the openings are pieced together. The middle part of the variable flowing deformation casing pipe installation hole directly penetrates through the stainless steel surface aluminium silicate composite board to integrally divide the stainless steel surface aluminium silicate composite board into two broken parts; and the upper end and the lower end of the variable flowing deformation casing pipe installation hole are arranged on the top stainless steel surface aluminium silicate composite board and the bottom stainless steel surface aluminium silicate composite board. The height of the hole on the top stainless steel surface aluminium silicate composite board and the height of the hole on the bottom stainless steel surface aluminium silicate composite board are smaller than the half of the integral width of the stainless steel surface aluminium silicate composite board. The combined assembling structure has the advantages that the stainless steel surface aluminium silicate composite board has good leakproofness and integral fire-proof performance, and the integral intensity of the stainless steel surface aluminium silicate composite board is guaranteed.

Description

technical field [0001] The invention relates to the technical field of bushing plugging on the converter valve side of a converter station, in particular to a combined assembly structure of an aluminum silicate composite plate with a stainless steel surface. Background technique [0002] The valve hall of the converter station is a closed building where the converter valve is placed. The design of the converter sleeve needs to be installed through the wall. When installing the converter sleeve, a fireproof structure needs to be set between the converter sleeve and the firewall to meet the fire protection requirements. The sealing structure of each joint in the fireproof structure needs to meet the requirements of good fireproofing, smoke insulation and waterproofing in daily operation and after a fire breaks out. Fireproof boards are usually composed of multiple boards. [0003] In the prior art, an application number 201910441087.9 is disclosed for a fire-proof and explos...

Problems solved by technology

[0004] The above-mentioned patents have played a role in fire prevention and explosion protection to a certain extent, but the fireproof board is composed of two layers of rock wool composite board with metal surface structure, and the temperature resistance is not high enough. Because the temperature resistance of stainless steel aluminum silicate composite board is higher, some will pass Aluminum silicate composite panels with stainless steel surfaces and rock wool composite panels with metal surfaces are used in combination to withstand and block higher temperatures; due to the large area of ​​fire prevention and sealing, usually multiple aluminum silicate surfaces with stainless steel composite The boards are assembled as a whole. There are longitudinal assembly and horizontal assembly. The longitudinal assembly forms multiple vertical joints. The sealing effect of the joints is poor, easy to deform at high temperature, and the overall fire performance is poor;

[0005] At the same time, as attached figure 1 As shown, in the prior art, when opening the rheological sleeve installation hole on the aluminum silicate composite plate on the stainless steel surface, if the installation hole of the rheological sleeve occupies a large area of ​​the aluminum silicate composite plate on the stainless steel surface, the replacement rheological sleeve installation hole is opened. The aluminum silicate composite plate on the stainless steel surface behind the installation hole of the rheological sleeve is divided into left and right parts by the installation hole of the rheological sleeve. The overall strength of the aluminum silicate composite plate is reduced, and more than one mounting hole for rheological sleeve is usually set on the aluminum silicate composite plate on the stainless steel surface, the overall strength of the aluminum silicate composite plate on the stainless steel surface is more affected, in order to strengthen the overall Intensity, it is necessary to strengthen the remaining plate after opening the installation hole of the rheological sleeve, increase the process and reduce the installation efficiency

Therefore, it is necessary to design a combined assembly structure of aluminum silicate composite panels on stainless steel surfaces to solve the above problems, so as to avoid the overall strength of aluminum silicate composite panels on stainless steel surfaces from reducing a lot
