[0002] In high-temperature industries such as metallurgy, glass, and ceramics, material flow and transport are critical components of the production process. As a crucial component for controlling material flow, the performance of nozzle bricks directly impacts production efficiency, product quality, and equipment life. With the continuous advancement of industrial technology, the requirements for high-temperature material flow control are becoming increasingly stringent. Zirconia corundum, due to its excellent resistance to high temperatures, wear, and chemical corrosion, has gradually become one of the ideal materials for nozzle bricks.
[0003] The current zirconium corundum flow nozzle brick is installed in the corresponding equipment or kiln to ensure its accurate position and to effectively guide the flow of materials. When the high-temperature material flows through the zirconium corundum flow nozzle brick, it flows through the shape and structure inside the zirconium corundum flow nozzle brick and is then transported to the subsequent work process.
[0004] The current zirconium corundum flow nozzle bricks have certain shortcomings. When high-temperature materials are circulated, the internal structure cannot buffer the impact of high-temperature materials, which can easily cause splashing of high-temperature solutions and threaten the personal safety of personnel. Secondly, during transportation, the bottom protection structure is unstable and will cause structural damage, resulting in deformation of the transportation structure, which is not conducive to better transportation.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] Reference Figure 1 、 Figure 2 and Figure 4 The utility model provides an embodiment: an inlaid zirconium corundum flow nozzle brick, including a nozzle brick body 1, which acts as a carrier to achieve the integrity of the overall structure. A feeding cavity 2 is provided inside the nozzle brick body 1. When the high-temperature material enters the feeding cavity 2, it can play a certain buffering role, so that the flow rate and pressure of the high-temperature material can be preliminarily adjusted and balanced, reducing the fluctuation of the flow of the high-temperature material. A buffer block 5 is provided on the top of the feeding cavity 2 to reduce the impact force of the high-temperature material and avoid damage to the structure of the nozzle brick body 1. A collection trough 3 is provided on the side wall of the nozzle brick body 1. The function of the collection trough 3 is to collect the high-temperature materials from different directions or channels together to prepare for the subsequent unified outflow, and to provide a certain storage space to buffer the unevenness or short interruption of the material supply, so as to ensure the continuous outflow of the material. A transition chamber 8 is provided at one end of the material trough 3. The function of the transition chamber 8 is to achieve a smooth transition from the feed chamber 2 to the discharge channel 7, avoid sudden changes in the flow of high-temperature materials, and reduce fluid resistance and energy loss. A discharge channel 7 is provided inside the nozzle brick body 1. Its main function is to ensure that the high-temperature material flows out accurately in a predetermined direction so as to enter subsequent process links or equipment. A discharge inclined body 6 is provided on the outer wall of the nozzle brick body 1 to control the shape of the discharge channel 7 and realize the state of transporting high-temperature materials to subsequent processes. A protective component is provided at the bottom of the nozzle brick body 1. The protective component is used for connecting and protecting the nozzle brick body 1. The aggregate trough 3 is symmetrically arranged on both sides of the inside of the nozzle brick body 1 to achieve stability. The aggregate trough 3 is arc-shaped, and the buffer blocks 5 are evenly distributed on the surface of the feed chamber 2. The feed chamber 2 is slightly higher than the discharge channel 7 to achieve a buffering effect.
[0024] Reference Figure 1-Figure 3The protection component includes a connecting block 4, which connects the carrier to the bottom protective shell 9 to protect the nozzle brick body 1. The connecting block 4 is fixedly connected to the side wall of the nozzle brick body 1. The outer wall of the connecting block 4 is slidably connected to the protective shell 9 to provide additional support and protection for the nozzle brick to prevent it from being damaged by external force such as squeezing and collision during use, and can block the erosion and pollution of the nozzle brick by external chemicals, dust and other impurities, thereby extending the service life of the nozzle brick. The inner wall of the protective shell 9 is provided with a connecting groove 10 for connecting with the connecting block 4 to achieve better fixed protection. The connecting groove 10 cooperates with the connecting block 4 to achieve fixed connection. The connecting block 4 and the connecting groove 10 are symmetrically arranged to achieve stability. The inner wall of the protective shell 9 is fixedly connected with a support body 11 to prevent the nozzle brick body 1 from falling off. The surface of the support body 11 is provided with a heat dissipation hole 12 to appropriately control the temperature of the nozzle brick body 1 to avoid damage caused by excessive temperature.
[0025] Reference Figure 1 、 Figure 2 and Figure 4 The discharge channel 7 is inclined, and the width of the discharge channel 7 becomes narrower and narrower, which determines the shape and distribution of the material when it flows out, and better provides a suitable material state for subsequent processes.
[0026] Working principle: First, connect the nozzle brick body 1 to the equipment, and then move the high-temperature material to the feed cavity 2. When the amount of high-temperature material increases, a certain amount of high-temperature material will be collected inside the side aggregate trough 3, and then the high-temperature material will first pass through the top of the buffer block 5 inside the nozzle brick body 1. At this time, the speed of the high-temperature material is reduced, and then the high-temperature material is buffered by the buffer block 5 inside the nozzle brick body 1 to avoid deformation and damage of the nozzle brick caused by impact force. Then the high-temperature material will pass through the discharge channel 7, and the amount of high-temperature material passing through will be reduced through the discharge inclined body 6. Finally, the infusion effect of subsequent work will be realized through the gate.
[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
