Description

Technical Field

[0001] The present application relates to the technical field of thermal insulation boards, and in particular to a reinforced thermal insulation board for a burner. Background Art

[0002] In the prior art, during use, the flame temperature at the end of the burner is above 800°C. In order to prevent the high temperature of the flame at the end from corroding the mixing components at the rear end of the burner, an insulation plate is usually installed on the upper part of the burner to achieve temperature isolation and protection. However, the existing insulation plate is usually a limestone asbestos board with a straight plate structure, which can only withstand a high temperature of about 600°C during use, and is prone to breakage after being subjected to high temperatures for a long time. Moreover, after being installed in the furnace, it also requires a thicker installation space. Utility Model Content

[0003] The problem to be solved by the present application is that the existing insulation board is usually a straight plate structure, which is not only easy to break during use due to poor high temperature resistance, but also requires more installation space in the furnace due to its thick physical size.

[0004] In order to solve the above technical problems, the present application provides a reinforced insulation board for a burner, including a plate body for fire prevention and heat insulation. The plate body is a rectangular structure and is pressed together with vermiculite and a certain amount of adhesive. There are multiple through holes of different sizes on the upper part of the plate body, which are used to place the air pipe, probe and ignition needle respectively. There are notches formed around the plate body to reduce the thickness required for installation of the insulation board.

[0005] Since the insulation board of the present application is designed with vermiculite material and notches, the high-temperature resistance and anti-cracking performance of the board can be improved by the vermiculite material, and the installation thickness of the board inside the furnace can be reduced by the arrangement of the notches, which solves the problem that the insulation board of the prior art is usually a straight plate structure, which is not only easy to break during use due to poor high-temperature resistance, but also requires more installation space in the furnace due to its thick physical size.

[0014] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application. Example

[0015] The present application relates to a reinforced thermal insulation board for a burner, such as Figure 1-7 As shown, the insulation board includes a board body 2 for fireproofing and heat insulation. The board body 2 is a rectangular structure. A plurality of through holes 3 of different sizes are opened on the upper part of the board body 2, which are respectively used to place the air pipe, the probe and the ignition needle. A notch 1 is formed around the board body 2 to reduce the thickness required for installation of the insulation board. In order to avoid the design of the notch 1 reducing the physical strength of the insulation board, the length ratio of the board body 2 to the notch 1 is 8.2:1, and the width ratio of the board body 2 to the notch 1 is 11.7:1. In order to improve the temperature resistance of the board body 2, the board body 2 is mainly formed by pressing vermiculite and a certain amount of adhesive. Therefore, the introduction of vermiculite can greatly improve the high temperature resistance of the board body 2, and avoid the board body 2 from breaking after being subjected to high temperature for a long time. In order to further improve the bearing strength of the plate body 2, a plurality of outwardly protruding ribs 5 are evenly and spaced apart on the back of the plate body 2, and channels 4 for air flow are formed between the ribs 5, so that the ribs 5 can not only improve the bearing strength of the plate body 2, but also improve the heat dissipation capacity of the plate body 2 with the help of the channels 4 between the ribs 5. In order to avoid improper thickness design of the ribs 5, which may result in no obvious improvement in its installation thickness or reduce the heat dissipation capacity, the thickness ratio between the plate body 2 and the ribs 5 is 1.67:1. In order to avoid unreasonable length design of the ribs 5, which may increase the weight of the plate body 2 and cause compressive deformation of the trachea, the length ratio of the plate body 2 and the ribs 5 is 5:1, and the width ratio of the plate body 2 and the ribs 5 is 17:1.

[0016] When in use, the through holes 3 of the plate body 2 are sequentially connected to the air pipe, probe and ignition needle, and then fixed to the inside of the furnace by bolts. During the combustion process of the burner, the plate body 2 can use its own high-temperature resistant vermiculite material to improve its heat resistance and crack resistance. After it is installed inside the furnace, the raised ribs 5 arranged on its surface can not only improve its bearing strength, but also form channels 4 for air heat dissipation flow between the ribs 5.

[0017] Generally speaking, terms should be understood, at least in part, based on the context in which they are used. For example, as used herein, the term "one or more" can be used to describe any feature, structure, or characteristic in the singular sense, or can be used to describe a combination of features, structures, or characteristics in the plural sense, depending at least in part on the context.
