Description

Technical Field

[0001] The utility model relates to the technical field of heat insulation of steel structures of metallurgical heating furnaces, in particular to a shallow refractory material construction device. Background Art

[0002] The heating furnace is a commonly used equipment in the metallurgical process. Its steel structures such as furnace door, furnace lining and columns are close to the high-temperature area of ​​the heating furnace and are continuously subjected to high-temperature baking. Therefore, it is necessary to install heat insulation devices or refractory devices on the surface of these steel structures to reduce the surface temperature of the steel structures in the high-temperature area and ensure their durability.

[0003] In the related art, there is a thermal insulation device that directly welds anchor hooks on the surface of the steel structure and then sets refractory materials. However, the refractory material attachment depth in the steel structure areas such as the furnace door, furnace lining and columns is shallow, resulting in poor adhesion. The refractory material is extremely easy to fall off, and the refractory material is a whole. Once it falls off, the subsequent falling speed will be accelerated, resulting in failure of the thermal insulation of the steel structure, so that the steel structure will still be baked and deformed by the high temperature area. In severe cases, production needs to be stopped for replacement or maintenance, reducing work efficiency. At the same time, the thermal insulation device on the furnace lining and the column is easily scratched by the furnace door and directly scratched on the refractory material, causing the refractory material to be scraped off. Utility Model Content

[0004] The purpose of the utility model is to provide a shallow refractory material construction device to solve at least one aspect of the problems and defects raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A shallow refractory material construction device, comprising:

[0007] A plurality of groups of heat-insulating frames, wherein the inner side walls of the plurality of groups of heat-insulating frames are staggeredly provided with a plurality of heat-insulating boards;

[0008] A plurality of the heat insulation panels form a plurality of grids within the heat insulation frame;

[0009] A plurality of the grids are filled with refractory materials;

[0010] A plurality of gaskets, one side of which is arranged at the junction of a plurality of adjacent grid bottoms, and the other side of which is connected to the steel structure body.

[0011] The shallow refractory material construction device according to this scheme has at least the following technical effects:

[0012] The shallow refractory material construction device is configured by staggeredly arranging a plurality of insulation boards on the inner wall of the insulation frame, wherein the insulation boards form a plurality of grids in the insulation frame, and by filling the plurality of grids with refractory materials, the bearing capacity of the refractory materials is decomposed into each grid, which not only improves the adhesion of each grid of refractory materials, but also the falling of a certain grid of refractory materials does not affect the use of other refractory materials; furthermore, one side of the plurality of gaskets is arranged at the junction of the bottoms of a plurality of adjacent grids, and the other sides of the plurality of gaskets are connected to the main body of the steel structure, thereby increasing the connection area between the device and the main body of the steel structure, making the device less likely to loosen or fall off, improving the stability and reliability of the device, and ensuring the insulation effect of the steel structure; at the same time, when the refractory material construction device arranged on the furnace lining and the column is scratched by the furnace door, its scraping force acts on the insulation boards of the plurality of grids, thereby preventing the furnace door from directly contacting the refractory materials and scraping off the refractory materials, thereby improving the service life of the refractory materials.

[0013] As a further solution of the utility model: a plurality of anchor hooks are arranged on the inner side walls of the plurality of grids and along the length and width of the inner side walls of the plurality of grids.

[0014] By arranging a number of anchor hooks on the inner walls of a number of grids and along the length and width of the inner walls of the grids, the supporting force of the refractory material can be increased, the refractory material can be more firmly fixed in the grid, and the displacement or cracking of the refractory material caused by thermal expansion and contraction during use can be prevented, and the refractory material can be prevented from falling off from the grid due to displacement or cracking, thereby improving the stability and use efficiency of the refractory material.

[0015] As a further solution of the utility model: the length directions of the plurality of anchor hooks are arranged perpendicular to the inner wall of the grid.

[0016] Since the length directions of the anchor hooks are perpendicular to the inner wall of the grid, the support force of the anchor hooks on the refractory material is more uniform, further improving the support effect of the anchor hooks, thereby preventing the refractory material from falling off from the grid due to displacement or cracking.

[0017] As a further solution of the utility model: the thickness of the side walls around the heat insulation frame is set to 5mm-10mm.

[0018] Since the thickness of the side walls around the insulation frame is set to 5mm-10mm, the side walls of the insulation frame can be set to different thicknesses according to different construction locations to avoid excessive consumption of materials and reduce production costs. At the same time, the side close to the high temperature area can be set thicker and the opposite side can be set thinner, which can achieve the insulation effect while reducing the weight of the device itself. It can be adjusted according to specific circumstances to better adapt to various usage ranges.

[0019] As a further solution of the utility model: the thickness of the heat insulation board is set to 2mm-4mm.

[0020] Since the thickness of the insulation board is set to 2mm-4mm, the thinner insulation board can conduct and reflect heat faster and improve the insulation efficiency. In addition, several insulation boards are arranged in the insulation frame, and the thinness of the insulation board can avoid excessive bearing capacity on the insulation frame and deformation of the insulation frame due to excessive load.

[0021] As a further solution of the utility model: the heat insulation frame and the heat insulation plate are independently selected from stainless steel plates or ceramic plates.

[0022] Since the insulation frame and the insulation board are independently selected from stainless steel plates or ceramic plates, both of which have good insulation effects, the insulation frame and the insulation board can be ensured not to be easily deformed or damaged during use, thereby improving the structural stability and safety of the device.

[0035] like Figure 1-3 The embodiment of the utility model shown is a shallow refractory material construction device, comprising: a plurality of groups of insulation frames 101, a plurality of insulation boards 102 are staggeredly arranged on the inner walls of the plurality of insulation frames 101; the plurality of insulation boards 102 form a plurality of grids 103 in the insulation frames 101; the plurality of grids 103 are filled with refractory materials 104; a plurality of gaskets 105, one side of the plurality of gaskets 105 is arranged at the junction of the bottom of a plurality of adjacent grids 103, and the other side of the plurality of gaskets 105 is connected to the steel structure body.

[0036] Specifically, the shallow refractory material construction device is provided by staggeredly arranging a plurality of insulation boards 102 on the inner wall of the insulation frame 101, the plurality of insulation boards 102 form a plurality of grids 103 in the insulation frame 101, and by filling the plurality of grids 103 with refractory materials 104, the bearing force of the refractory materials 104 is decomposed into each grid 103, which not only improves the adhesion of each grid of refractory materials 104, but also the falling of a certain grid of refractory materials 104 does not affect the use of other refractory materials 104; furthermore, one side of the plurality of gaskets 105 is arranged on the plurality of adjacent grids. At the junction of the bottom of the grid 103, the other sides of several gaskets 105 are connected to the main body of the steel structure, which increases the connection area between the device and the main body of the steel structure, makes the device not easy to loosen or fall off, improves the stability and reliability of the device, and ensures the thermal insulation effect of the steel structure; at the same time, when the refractory material construction device arranged on the furnace lining and the column is scratched by the furnace door, its scraping force acts on the insulation board 102 of several grids 103, avoids the furnace door directly contacting the refractory material 104 and scraping the refractory material 104, thereby improving the service life of the refractory material 104.

[0037] like Figure 2 As shown, a plurality of anchor hooks 106 are disposed on the inner side walls of the plurality of grids 103 and along the length and width of the inner side walls of the grids 103 .

[0038] Specifically, by arranging a plurality of anchor hooks 106 on the inner walls of a plurality of grids 103 and along the length and width of the inner walls of the grids 103, it is possible to increase the supporting force of the refractory material 104, so that the refractory material 104 can be more firmly secured within the grids 103, thereby preventing the refractory material 104 from being displaced or cracked due to thermal expansion and contraction during use, and preventing the refractory material from falling off the grids 103 due to displacement or cracking, thereby improving the stability and use efficiency of the refractory material 104.

[0039] like Figure 3 As shown, the length directions of the plurality of anchor hooks 106 are all arranged perpendicular to the inner wall of the grid 103 .

[0040] Specifically, since the length directions of the anchor hooks 106 are perpendicular to the inner wall of the grid 103, the support force of the anchor hooks 106 on the refractory material 104 is more uniform, further improving the support effect of the anchor hooks 106, thereby preventing the refractory material 104 from falling off from the grid due to displacement or cracking.

[0041] According to the embodiment of the present invention, the thickness of the side walls around the heat insulation frame 101 is set to 5mm-10mm.

At the same time, the side close to the high temperature area can be set thicker and the opposite side can be set thinner, which can achieve the insulation effect while reducing the weight of the device itself. It can be adjusted according to specific circumstances to better adapt to various usage ranges.

[0043] According to an embodiment of the present invention, the thickness of the heat insulation board 102 is set to 2 mm-4 mm.

In addition, a plurality of insulation boards 102 are arranged in the insulation frame 101, and the thinness of the insulation board 102 can avoid causing excessive bearing force on the insulation frame 101, thereby avoiding deformation of the insulation frame 101 due to excessive bearing.

[0045] It should also be noted that the heat insulation frame 101 and the heat insulation plate 102 are independently selected from stainless steel plates or ceramic plates.

[0046] Specifically, since the insulation frame 101 and the insulation plate 102 are independently selected from stainless steel plates or ceramic plates, both of which have good insulation effects, the insulation frame 101 and the insulation plate 102 can be ensured not to be deformed or damaged during use, thereby improving the structural stability and safety of the device.
