Description

Technical Field

[0001] This utility model belongs to the field of horizontal boiler membrane wall technology, and particularly relates to a horizontal boiler partition membrane wall structure. Background Technology

[0002] Membrane wall structures are a type of structure widely used in boilers, pressure vessels, and buildings. Their core feature is that steel plates or pipes are tightly connected to form a continuous, sealed wall surface through welding. For example, Chinese utility model patent CN202322552031.5 discloses a fully sealed membrane wall structure for a gas-fired boiler using a pipe end reduction process. With the advancement of relevant safety and energy-saving policies, steam boilers are required to be miniaturized, which allows boilers using membrane wall structures to be further reduced in size.

[0003] However, the steam boiler core with a membrane wall structure, as disclosed in Chinese utility model patent CN202322552031.5, is connected by welding. This poses risks of welding stress and deformation, as residual stress can easily be generated during the welding process, potentially leading to structural deformation. Maintenance is difficult; localized damage (such as weld cracking) may require extensive dismantling and repair, resulting in long downtime. If the membrane wall malfunctions, the limited space may prevent operation altogether. Summary of the Invention

[0004] The purpose of this utility model embodiment is to provide a horizontal boiler partition membrane wall structure, which aims to solve the technical problem that the intermediate membrane wall in the horizontal boiler membrane wall structure is not easy to disassemble and is difficult to maintain.

[0005] The present invention is implemented as follows:

[0006] A horizontal boiler partition membrane wall structure is characterized in that the partition membrane wall structure includes a left membrane wall, a right membrane wall, and a partition membrane wall. The left and right membrane walls are D-shaped. The top of the large ends of the left and right membrane walls are connected to the two sides of an upper manifold, and the bottom of the large ends of the left and right membrane walls are connected to the two sides of a lower manifold. The upper and lower manifolds are detachably connected together through the partition membrane wall. A connecting part is provided at the connection between the partition membrane wall and the upper or lower manifold, and the connecting part is fixed to the partition membrane wall and the upper or lower manifold by bolts or plug-in.

[0007] Furthermore, the partition wall membrane is made of solid wood.

[0008] Furthermore, the partition wall membrane is a plate with a water pipe running through it, and the water pipe is sealed to connect the upper manifold and the lower manifold.

[0009] Furthermore, the partition wall membrane wall panel has water pipes that are distributed alternately and welded together to form a wall-like structure, wherein the water pipes connect the upper manifold and the lower manifold.

[0010] Furthermore, the connecting part includes a plug-in part welded to the connecting seat and connected within the connecting seat and fixed to the end of the partition membrane wall, the plug-in part having a rectangular cross-section.

[0011] Furthermore, the connector can be a fixed connector or a plug-in connector.

[0012] Furthermore, the fixing base includes a fixing plate welded to the lower part of the upper manifold by welding points. A pair of upright plates are symmetrically arranged on both sides of the fixing plate. A pad is provided on the inner side of the upright plate for adjusting the width inside the fixing base. A soft metal contact plate is fixed on the inner side of the pad. The bolt passes through the solid plate or the part of the plate without water pipes, and fixes the partition membrane wall in the connecting base through the plug-in part. The plug-in part is located between the contact plates. The soft metal is an aluminum plate or a copper plate.

[0013] Furthermore, the connector is symmetrically provided with multiple layers of metal sealing springs. The side of the connector is in sealing contact with the multiple layers of metal sealing springs. The connector includes a connecting plate welded to the lower part of the upper manifold by welding points. The connecting plate has side plates on both sides. At least three layers of sealing springs are welded to the inner side of the side plates. The connector is inserted between the symmetrical sealing springs, and the side of the connector is in sealing contact with the multiple layers of sealing springs.

[0014] The positive effects of this utility model are: by using a method in which the upper and lower manifolds are detachably connected together through a membrane wall, the membrane wall can be detachably connected between the upper and lower manifolds. In this way, when maintenance is required, the membrane wall can be disassembled by removing the bolt-fixed or plug-in structure for maintenance. At the same time, it also increases the operating space available for maintenance within the space enclosed by the membrane wall, solving the technical problem that the middle membrane wall in the horizontal boiler membrane wall structure is not easy to disassemble and is difficult to maintain.
