Description

Technical Field

[0001] This utility model relates to the field of material leakage hole brick technology, specifically a material leakage hole brick with a high zirconium brick inner sleeve embedded in it. Background Technology

[0002] Leakage hole bricks are key components in the bottom structure of glass melting furnaces, used to prevent or handle leakage accidents. Currently, the melting pool walls of domestic glass furnaces use fused zirconia-corundum bricks (referred to as fused AZS). Based on the zirconium dioxide content, fused zirconia-corundum bricks are available in AZS33#, AZS36#, and AZS41#, representing ZrO2 contents of 33%, 36%, and 41%, respectively. Fused zirconia-corundum pool wall bricks are made from industrial alumina and zircon sand (containing approximately 65% ​​ZrO2 and 34% SiO2), with the addition of some soda ash (Na2CO3), melted and cast in an electric arc furnace. Existing leakage hole bricks are mostly made from corundum, zircon, corundum-zirconia eutectic, and glass phase materials. They are mostly rectangular in shape, with two leakage holes inside the brick. When laid, the upper and lower layers of leakage hole bricks are staggered in an I-shape. In the event of leakage, the leakage hole bricks can serve as pressure relief or drainage channels to prevent molten glass from leaking out. The traditional perforated bricks, with their smooth surfaces and lack of precise positioning, cannot accurately create a staggered effect between the upper and lower layers, leading to a high risk of glass penetration. Furthermore, the bricks contain 15% low-melting-point glass phase, causing the glass phase to continuously precipitate onto the surface under high-temperature conditions. This constant physical erosion by the flowing high-temperature glass creates voids in the brick's internal structure. The high-temperature glass then gradually penetrates and erodes the brick, eventually becoming a metamorphic layer before detaching and flowing into the glass. Under the combined effects of physical erosion and chemical corrosion, the thickness of the furnace wall bricks continuously decreases. When the thickness reaches 60-80mm, additional brick binding or furnace shutdown for maintenance becomes necessary, resulting in maintenance or production losses and increasing production costs for glass manufacturers. Therefore, we propose a perforated brick with an embedded high-zirconium brick inner sleeve. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a leakage hole brick with a high zirconium brick inner sleeve embedded in it. It is equipped with a nesting mechanism, in which a high zirconium inner sleeve is nested inside the leakage hole of the leakage hole brick. The corrosion resistance of the high zirconium inner sleeve improves the service life of the leakage hole brick. It can also make the upper and lower layers of leakage hole bricks form an accurate I-shaped misalignment through the positioning component, reducing the risk of glass melt penetration. It can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a material leakage hole brick with a high zirconium brick inner sleeve, comprising a brick body and a nesting mechanism;

The nesting mechanism, in which a high-zirconium inner sleeve is nested inside the leakage hole of the leakage hole brick, improves the service life of the leakage hole brick through the corrosion resistance of the high-zirconium inner sleeve. It can also make the upper and lower layers of leakage hole bricks form an accurate I-shaped misalignment through the positioning component, reducing the risk of glass melt penetration.

[0007] Furthermore, the nesting mechanism also includes flow guide grooves. Flow guide grooves are provided on the left and right side walls of both the upper and lower high-zirconium inner sleeves to provide a flow guide effect for pressure relief and discharge operations.

[0010] Furthermore, the first positioning groove corresponds vertically to the first positioning protrusion, the second positioning groove corresponds vertically to the second positioning protrusion, and the third positioning groove corresponds vertically to the third positioning protrusion, which can make the upper and lower layers of material leakage hole bricks form an accurate I-shaped misalignment.

[0011] Furthermore, it also includes a connecting groove and a connecting protrusion. The connecting groove is located in the middle right side of the brick body, and the connecting protrusion is located in the middle left side of the brick body. The connecting groove and the connecting protrusion are installed together to provide a connection effect for two adjacent bricks with leakage holes.

[0012] Furthermore, it also includes inclined grooves, which are respectively opened in the middle of the front and rear sides of the brick body to facilitate the removal of the brick with the material leakage hole.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This embodiment provides a technical solution: a material leakage hole brick embedded with a high zirconium brick inner sleeve, including a brick body 1 and a nesting mechanism 4;

[0022] Brick 1: It has material leakage holes 2 on both the front and back sides inside. Brick 1 is an AZS material leakage hole brick. It also has notches 3 at both the top and bottom ends.

[0023] Nesting mechanism 4: It includes an upper high-zirconium inner sleeve 41, a lower high-zirconium inner sleeve 42, a guide groove 43, a guide protrusion 44, and a positioning component 46. The upper high-zirconium inner sleeve 41 is located at the upper end of the material leakage hole 2, and the lower high-zirconium inner sleeve 42 is located at the lower end of the material leakage hole 2. Both the upper high-zirconium inner sleeve 41 and the lower high-zirconium inner sleeve 42 are made of high-zirconium bricks, which are fireproof brick materials. The main component is zirconia, which has extremely high corrosion resistance. Both the upper high-zirconium inner sleeve 41 and the lower high-zirconium inner sleeve 42 are installed in conjunction with the laterally adjacent recesses 3. The outer edges of the upper high-zirconium inner sleeve 41 and the lower high-zirconium inner sleeve 42 are fitted with the laterally adjacent recesses 3, so that the left and right ends of the upper high-zirconium inner sleeve 41 and the lower high-zirconium inner sleeve 42 are flush with the left and right ends of the brick body 1, thus preventing the brick body 1 from being corroded. The guide grooves 43 are respectively opened in... At the upper and lower ends of the inner wall of the material leakage hole 2, the outer surfaces of the high-zirconium inner sleeve 41 and the lower high-zirconium inner sleeve 42 are provided with guide protrusions 44. The outer surfaces of the guide protrusions 44 are slidably connected to the inner walls of the vertically adjacent guide grooves 43. The service life of the material leakage hole brick is improved by the corrosion resistance of the nested high-zirconium inner sleeves. The nesting mechanism 4 also includes a guide groove 45. The left and right side walls of the upper high-zirconium inner sleeve 41 and the lower high-zirconium inner sleeve 42 are provided with guide grooves 45. The guide grooves 45 only extend to the lower end of the inner wall of the lower high-zirconium inner sleeve 42, providing a guiding effect for pressure relief and discharge. The positioning components 46 are all set on the side away from the middle of the brick body 1. The positioning components 46 include positioning groove one 461, positioning groove two 462 and positioning groove three 463. Positioning groove one 461 is respectively opened on the upper high-zirconium inner sleeve 42. On the front and rear sides of the upper end of the zirconium inner sleeve 41, positioning grooves 2 462 are respectively opened on the front and rear sides of the upper end of the brick body 1, and positioning grooves 3 463 are respectively opened on the left and right sides of the middle of the upper end of the brick body 1. The positioning groove 1 461 far from the middle of the brick body 1 and the vertically adjacent positioning groove 2 462 form a positioning round hole, and the positioning groove 1 461 near the middle of the brick body 1 and the vertically adjacent positioning groove 2 462 form a positioning square hole, providing positioning holes for laying the material leakage hole brick. The positioning component 46 also includes positioning protrusion 1 464, positioning protrusion 2 465 and positioning protrusion 3 466. Positioning protrusion 1 464 is respectively set on the front and rear sides of the lower end of the lower zirconium inner sleeve 42, and positioning protrusion 2 465 is respectively set on the front of the lower end of the brick body 1. On the rear two sides, positioning protrusions 3 466 are respectively set on the left and right sides of the lower middle part of the brick body 1. The positioning protrusion 1 464 far from the middle of the brick body 1 and the vertically adjacent positioning protrusion 2 465 form a circular protrusion. The positioning protrusion 1 464 near the middle of the brick body 1 and the vertically adjacent positioning protrusion 3 466 form a square protrusion, providing positioning posts for the laying of the perforated brick. Positioning groove 1 461 is vertically corresponding to positioning protrusion 1 464, positioning groove 2 462 is vertically corresponding to positioning protrusion 2 465, and positioning groove 3 463 is vertically corresponding to positioning protrusion 3 466. This can make the upper and lower layers of perforated bricks form an accurate I-shaped misalignment. A nesting mechanism 4 is provided, in which a high zirconium inner sleeve is nested inside the perforation hole 2 of the perforated brick.The high-zirconium inner sleeve enhances the corrosion resistance of the leakage hole bricks, and the positioning component 46 ensures accurate I-shaped misalignment between the upper and lower layers of leakage hole bricks, reducing the risk of molten glass penetration.

[0024] The working principle of the material leakage hole brick with an embedded high-zirconium brick inner sleeve provided by this utility model is as follows: When producing the material leakage hole brick with an embedded high-zirconium brick inner sleeve, the prepared material leakage hole brick is first heated to expand it. Then, the upper high-zirconium inner sleeve 41 and the lower high-zirconium inner sleeve 42 are respectively embedded into the interior of the material leakage hole 2. During this process, the material leakage hole of the material leakage hole brick expands and enlarges due to the principle of thermal expansion and contraction. Then, the guide protrusions 44 on the outer surfaces of the upper high-zirconium inner sleeve 41 and the lower high-zirconium inner sleeve 42 are respectively aligned with the corresponding guide grooves 43. Then, the upper high-zirconium inner sleeve 41 and the lower high-zirconium inner sleeve 42 are inserted into the interior of the material leakage hole 2. After the material leakage hole brick cools down, the material leakage hole shrinks, and the upper high-zirconium inner sleeve 41 and the lower high-zirconium inner sleeve 42 are embedded inside the material leakage hole brick. Then, the material leakage hole brick is laid at the bottom of the glass melting furnace. First, high-alumina refractory mortar is used for leveling to avoid uneven stress on the brick due to uneven base layer. Then, the leakage hole bricks are laid sequentially on the bottom of the pool. The connecting groove 5 of the middle leakage hole brick is inserted into the connecting protrusion 6 of the right leakage hole brick, while the connecting protrusion 6 is inserted into the connecting groove 5 of the left leakage hole brick. This process is repeated. When laying the second layer of leakage hole bricks, the second layer of leakage hole bricks is staggered with the first layer of leakage hole bricks in an I-shape. During laying, the positioning round holes on the right side of the second layer of leakage hole bricks are inserted into the round protrusions on the left side of the first layer of leakage hole bricks, and the positioning square holes on the right side of the second layer of leakage hole bricks are inserted into the square protrusions on the left side of the first layer of leakage hole bricks. This allows the upper and lower layers of leakage hole bricks to form an accurate I-shape staggered position. When leakage occurs, the guide grooves 45 on the surfaces of the upper high-zirconium inner sleeve 41 and the lower high-zirconium inner sleeve 42, combined with the I-shape staggered leakage hole bricks, can quickly form a pressure relief and discharge channel, effectively reducing the risk of glass melt penetration.

[0025] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
