Description

Technical Field

[0001] This utility model relates to the field of gasification furnace technology, specifically to a shaped refractory brick for gasification furnace lining. Background Technology

[0002] Refractory bricks, as the name suggests, are brick-shaped refractory materials that can withstand high temperatures without easily being damaged. Their main characteristics include high refractoriness, good thermal shock resistance, excellent resistance to slag erosion, and a certain degree of mechanical strength.

[0003] For example, a shaped refractory brick and kiln lining structure with authorization announcement number "CN218955476U" uses multiple anti-expansion gaps to buffer the thermal expansion of the shaped refractory brick when heated, ensuring the stability of the lining structure; effectively improving the stability and heat insulation of the kiln lining at high temperatures and preventing structural damage caused by thermal expansion. However, this device requires operators to handle and install the entire refractory brick by hand. When the working environment is relatively confined, the device is not convenient to hold, making its use inconvenient. Utility Model Content

[0004] The purpose of this invention is to solve the problem of inconvenience in using the device, and to propose a special-shaped refractory brick for the lining of a gasifier.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a special-shaped refractory brick for gasifier lining, including a first refractory brick and a second refractory brick. The inner wall of the first refractory brick is in contact with the second refractory brick. The inner walls of both the first and second refractory bricks are provided with grooves. One end of both the first and second refractory bricks is fixedly connected with a protrusion. The other end of both the first and second refractory bricks is provided with a circular groove.

[0007] Preferably, a protrusion at one end of the first refractory brick is inserted into a circular groove at one end of the first refractory brick that is counterclockwise adjacent to it, and a protrusion at one end of the second refractory brick is inserted into a circular groove at one end of the second refractory brick.

[0008] Preferably, one end of the first refractory brick is attached to the other end of the first refractory brick that is counterclockwise adjacent, and one end of the second refractory brick is attached to the other end of the second refractory brick that is counterclockwise adjacent.

[0009] The present invention proposes a special-shaped refractory brick for gasifier lining, which has the following advantages: By cooperating with the first and second refractory bricks, the operator fits one first refractory brick against the inner wall of the gasifier, and inserts the protrusion of the second refractory brick into the circular groove of the first refractory brick. According to the above operation, multiple first refractory bricks are spliced ​​to the inner wall of the gasifier. Similarly, a ring of second refractory bricks is installed on the inner wall of the first refractory bricks. The gap between two second refractory bricks is misaligned with the gap between two first refractory bricks, which improves the sealing performance. When the space is narrow, the operator can reach into the groove to move the brick, making the installation more convenient. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings:

[0016] See attached document Figure 1-4 In this embodiment, a shaped refractory brick for gasifier lining includes a first refractory brick 1 and a second refractory brick 4. The inner wall of the first refractory brick 1 is in contact with the second refractory brick 4. The inner walls of both the first refractory brick 1 and the second refractory brick 4 are provided with grooves 5. A protrusion 2 at one end of a first refractory brick 1 is inserted into a circular groove 3 at one end of a counterclockwise adjacent first refractory brick 1. The protrusion 2 at one end of a second refractory brick 4 is inserted into a circular groove 3 at one end of a second refractory brick 4. One end of a first refractory brick 1 is in contact with the other end of a counterclockwise adjacent first refractory brick 1. One end of a second refractory brick 4 is in contact with the other end of a counterclockwise adjacent second refractory brick 4. The first refractory brick 1 and the second refractory brick 4 are high-alumina bricks and are both shaped bricks.

[0017] Working principle:

[0018] When installing irregularly shaped refractory brick linings inside the gasifier:

[0019] The operator attaches a first refractory brick 1 to the inner wall of the gasifier, and inserts the protrusion 2 of the second refractory brick 1 into the circular groove 3 of the first refractory brick 1 (a gap is left between the adjacent end faces of the two first refractory bricks 1 to provide buffer space after high-temperature expansion, and there is also a gap between the protrusion 2 and the circular groove 3). Following the above operation, multiple first refractory bricks 1 are spliced ​​to the inner wall of the gasifier. Similarly, a ring of second refractory bricks 4 is installed on the inner wall of the first refractory bricks 1. The gap between the two second refractory bricks 4 is offset from the gap between the two first refractory bricks 1 to improve a certain degree of sealing. When the space is narrow, the operator can put their hand into the groove 5 for handling (the groove 5 does not penetrate the first refractory brick 1 and the second refractory brick 4, and the groove 5 can increase the force point during handling), making the installation more convenient.

[0020] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
