Description

Technical Field

[0001] This utility model belongs to the field of refractory brick technology, specifically a refractory brick that can quickly remove moisture. Background Technology

[0002] Refractory bricks are made from refractory clay or other refractory materials and are used to construct equipment such as blast furnaces and kilns that need to withstand high temperatures. When not in operation, refractory bricks accumulate moisture inside. This moisture vaporizes and expands at high temperatures. Existing refractory bricks lack drainage and steam venting channels, making it impossible to expel the generated moisture and steam in a timely manner. When heated, the pressure difference between the inside and outside of the refractory brick can easily cause it to crack, damaging the brick and consequently affecting the safe operation of the equipment. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a refractory brick that can quickly remove moisture.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A refractory brick for rapid moisture removal includes sidewalls, grooves, a first connector, a vertical through hole, a second connector, and a vertical through groove. There are two sidewalls and two first connectors. The two first connectors are respectively clamped at both ends of the inner sidewalls of the two sidewalls. The second connector is clamped at the center of the inner sidewalls of the two sidewalls and the vertical through hole is opened at the top center. The outer sidewalls of the two sidewalls are provided with grooves. The vertical through groove is provided on the outer side of the first connector. The sidewalls, the first connector, and the second connector are an integral structure.

[0005] Furthermore, the groove is composed of a horizontal sub-groove connecting two vertical sub-grooves, and the edges at the intersection of the horizontal and vertical sub-grooves are rounded.

[0006] Furthermore, the upper surface of the first connector is inclined upward along the direction close to the second connector, and a transverse through hole is formed on the side along the direction close to the second connector.

[0007] Furthermore, the transverse through hole is inclined upward along the direction close to the second connector.

[0008] Furthermore, the upper surface of the sidewall has upward protrusions at both ends, and the lower surface has upward depressions at both ends.

[0009] Furthermore, the bottoms of both the first and second connectors are parallel to the upwardly recessed upper surface, and their top heights are the same and both are lower than the height of the sidewall.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1) Through holes and grooves in refractory bricks reduce the weight of refractory bricks without affecting their stability, and increase the timely discharge of moisture and steam while reducing heat absorption; 2) Replacing right-angle bends at intersections with rounded corners can prevent cracking at the intersections of horizontal and vertical sub-grooves due to heat accumulation and large temperature differences with the surrounding environment, thus improving the service life of refractory bricks. 3) The top of the first connector and the transverse through hole are both inclined upwards in the direction close to the second connector, so as to ensure that when the refractory bricks are stacked, dust and other debris are not easy to enter the internal space of the brick through the vertical through groove and thus adhere to the surface of the brick or block the transverse or longitudinal channels inside the brick. 4) The protrusion at the top and the recess at the bottom of the side wall 1 facilitate the interlocking of refractory bricks when stacked to increase the stability of the overall structure, and the recess at the bottom facilitates the lifting of refractory bricks from the bottom. 5) The top height of the first and second connecting bodies is lower than that of the side walls, which allows steam to move laterally as it moves along the vertical through holes or cavities, making the vertical through holes, horizontal through holes and vertical channels interconnected, which is conducive to the timely discharge of steam.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0015] In this utility model, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0016] Example See Figure 1 and Figure 2 The refractory brick for rapid moisture drainage includes a side wall 1, a groove 2, a first connector 3, a vertical through hole 4, a second connector 5, and a vertical through groove 7. There are two side walls 1 and two first connectors 3, each clamped at one end of the inner surface of the two side walls 1. The second connector 5 is clamped at the center of the inner surface of the two side walls 1, with the vertical through hole 4 located at its top center. The side wall 1, the first connector 3, and the second connector 5 are a single integrated structure. The bottoms of both the first connector 3 and the second connector 5 are parallel to the upwardly recessed upper surface, and their tops are at the same height and lower than the height of the side wall 1.

[0017] Both of the upper surfaces of the first connecting bodies 3 are inclined upwards along the direction close to the second connecting body 5, and horizontal through holes 6 are formed on the side surfaces along the direction close to the second connecting body 5. The first connecting bodies 3 and the second connecting bodies 5 have the same height and are both lower than the height of the side wall 1. The vertical through groove 7 formed by the first connecting body 3 and the two side walls 1 is provided on the outer side surface of the first connecting body 3.

[0018] The vertical channel formed between the two first connecting bodies 3 and the second connecting body 5 is continuous from top to bottom. Each of the two sidewalls 1 has a groove 2 on its outer surface. The groove 2 is composed of a horizontal sub-groove that runs horizontally through the middle and connects two vertical sub-grooves. The edges at the intersection of the horizontal and vertical sub-grooves are rounded. Both ends of the horizontal and vertical sub-grooves are continuous. The upper surfaces of both sidewalls 1 have upward protrusions at both ends, and the lower surfaces have upward indentations at both ends.

[0019] When the refractory brick is heated, the moisture is collected in the groove 2 on the outer side of the sidewall 1 and discharged through the vertical sub-groove, or through the vertical through hole 4 or the vertical channel, or guided to the vertical through slot 7 through the horizontal through hole 6; the generated steam can be discharged through the vertical sub-groove, the vertical through hole 4, the vertical channel or the vertical through slot 7.

[0020] Since the sidewall 1 directly bears the impact of high temperature, to prevent cracking at the intersection of the horizontal and vertical sub-grooves due to heat accumulation and large temperature difference with the surrounding environment, the right-angle bend at the intersection is changed to a rounded corner. The vertical channel is a hollow structure formed by the sidewall 1, the first connecting body 3, and the second connecting body 5. It reduces the weight of the refractory bricks without affecting their stability, while reducing heat absorption and increasing the timely discharge of moisture and steam. The protrusion at the top and the recess at the bottom of the sidewall 1 facilitate interlocking when the refractory bricks are stacked, increasing the stability of the overall structure, and the recess at the bottom facilitates lifting the refractory bricks from below. The top of the first connecting body 3 and the horizontal through-hole 6 are both inclined upwards towards the second connecting body 5, ensuring that dust and other debris do not easily enter the brick's internal space through the vertical through-groove 7 when the refractory bricks are stacked. The fact that the top height of the first connecting body 3 and the second connecting body 5 is lower than that of the side wall 1 allows steam to move laterally as it moves along the vertical through hole or cavity, so that the vertical through hole 4, the horizontal through hole 6 and the vertical channel are interconnected. This facilitates the timely discharge of steam, reduces the local increase in temperature and humidity caused by local blockage, and improves the service life of refractory bricks.

[0021] Finally, it should be noted that the above embodiments are merely preferred embodiments of this utility model, and are only used to illustrate the technical solution of this utility model and not to limit it. Any modifications, improvements, or other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be included within the protection scope of this utility model.
