Description

Technical Field

[0001] The utility model belongs to the technical field of boiler enclosure, and particularly relates to a connection structure between the operation layer and the furnace of a boiler. Background Art

[0002] At present, due to the temperature factor of the project site, there are mainly three types of boiler enclosure structures: fully enclosed, semi-enclosed, and open layout. Among them, the semi-enclosed structure is enclosed below the operation layer and open above the operation layer. The operation layer adopts a concrete floor slab structure. Since there is a certain gap between the boiler furnace and the concrete floor slab of the operation layer, and the three-way deformation of the furnace is relatively large, the enclosure between the furnace and the operation layer floor slab is poor. Content of the Utility Model

[0003] In view of this, the utility model aims to provide a connection structure between the operation layer and the furnace of a boiler to solve the problem that there is a certain gap between the existing boiler furnace and the concrete floor slab of the operation layer, and the three-way deformation of the furnace is relatively large, resulting in poor sealing between the furnace and the operation layer floor slab.

[0004] To achieve the above object, the utility model adopts the following technical solutions:

[0005] A connection structure between the operation layer and the furnace of a boiler, comprising a furnace rigid beam, an operation layer floor slab, and a skin component. The skin component is arranged on the furnace rigid beam, and the end of the operation layer floor slab is connected to the skin component.

[0006] Furthermore, the skin component includes a lower skin and an upper skin. The upper skin is located above the lower skin. One end of the lower skin and the upper skin is connected to the operation layer floor slab, and the other end is connected to the furnace rigid beam.

[0007] Furthermore, an upper cover plate is arranged above the upper skin. The upper cover plate is connected to the furnace rigid beam through a cover plate support member.

[0008] Furthermore, heat insulation material is filled between the lower skin and the upper skin.

[0009] Furthermore, the heat insulation material is made of heat insulation cotton.

[0010] Furthermore, a drain port and a drain trough are arranged at the end of the operation layer floor slab. The drain port is arranged on one side of the drain trough. The drain trough is connected to the lower skin, and the drain port is located below the upper cover plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model uses a skin material with large deformation ability, fills heat-insulating material in the middle, connects the floor slab and the furnace chamber, digests the three-dimensional deformation of the furnace chamber through the skin, realizes the closed function below the operating layer, and ensures that heat is not lost during winter heating.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other. The described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0017] See Figure 1 In this embodiment, a connection structure for a boiler operating layer and a furnace chamber includes a furnace rigid beam 1, an operating layer floor slab 4, and a skin component. The skin component is arranged on the furnace rigid beam 1. The end of the operating layer floor slab 4 is connected to the skin component. The skin component includes a lower skin 7 and an upper skin 9. The upper skin 9 is located above the lower skin 7. One end of the lower skin 7 and the upper skin 9 is connected to the operating layer floor slab 4, and the other end is connected to the furnace rigid beam 1. An upper cover plate 2 is arranged above the upper skin 9. The upper cover plate 2 is connected to the furnace rigid beam 1 through a cover plate support 3. Heat-insulating material 8 is filled between the lower skin 7 and the upper skin 9. The heat-insulating material 8 uses heat-insulating cotton. A drain opening 5 and a drainage trough 6 are arranged at the end of the operating layer floor slab 4. The drain opening 5 is arranged on one side of the drainage trough 6. The drainage trough 6 is connected to the lower skin 7. The drain opening 5 is located below the upper cover plate 2.

[0018] Add thermal insulation cotton between the two skins. One end of the two skins is connected to the operating floor slab 4, and the other end is connected to one side of the drain trough 6. The other side of the drain trough 6 is connected to the operating floor slab 4. There is an upper cover plate 2 above the upper skin 9. The upper cover plate 2 is used for flashing, so that the water flowing down from above flows into the drain trough 6 and is drained centrally through the drain opening 5. This connection structure uses a skin material with a large deformation capacity to digest the three-dimensional deformation of the furnace chamber, realizing the closed function below the operating floor slab 4. And there is a thermal insulation material 8 between the upper skin 9 and the lower skin 7, which can improve the thermal insulation effect and ensure that the heat does not escape during winter heating.
