[0026] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0027] In this disclosure, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" generally refer to the upper, lower, top, and bottom of the corresponding component in the direction of gravity when in use, while "inner" and "outer" refer to the inner and outer contours relative to the component or structure itself. Furthermore, it should be noted that terms such as "first" and "second" are used to distinguish one element from another and do not indicate sequence or importance. Additionally, in the description with reference to the accompanying drawings, the same reference numerals in different drawings denote the same element.

[0028] like Figure 1 As shown, this disclosure provides a nozzle brick assembly, including: a brick body 2 for installation into the side wall of a kiln 1 from the outside, the brick body 2 having an installation hole 21 for installing a combustion gun and a mixing channel 22 connected to the installation hole 21 and penetrating the brick body 2, the mixing channel 22 communicating with a flame nozzle 102 in the side wall of the kiln 1, one end of the brick body 2 extending out of the kiln 1 and inclined downward; and an anchoring device 3 for being disposed outside the kiln 1, one end of the anchoring device 3 being connected to the portion of the brick body 2 extending out of the kiln 1 to fix or pull the brick body 2 out of the side wall of the kiln 1.

[0029] With the above technical solution, the brick 2 is installed on the side wall of the kiln 1 from the outside, which facilitates installation and disassembly. A mixing channel 22 is provided inside the brick 2, one end of which is connected to the combustion gun, and the other end is connected to the flame nozzle 102. The outer end of the brick 2 is inclined downwards, making it easier to remove. However, this can cause the brick 2 to slip, so an anchoring device 3 is installed to fix the brick 2. When it is necessary to replace the brick 2, it can be pulled out using the anchoring device 3. Furthermore, since one end of the brick 2 extends beyond the kiln 1, this end does not contact the side wall of the kiln 1, reducing the contact area between the brick 2 and the kiln 1, thereby reducing friction and making it easier to remove. It also increases the exposed area of ​​the brick 2, which in turn increases the operating area and thus the operating space.

[0030] As an optional implementation method, such as Figure 1 As shown, the end of the brick 2 facing the inside of the kiln 1 is constructed with a wedge-shaped structure. The wedge-shaped structure has less friction with the side wall of the kiln 1 compared to the rectangular structure, making it easier to remove.

[0031] Optionally, such as Figure 3 As shown, the brick body 2 is symmetrically arranged at both ends facing the inner and outer sides of the kiln 1. On the one hand, the outer part of the brick body 2 is also a wedge-shaped structure, which occupies less space and prevents interference with other devices outside the kiln 1. On the other hand, both ends of the brick body 2 can be inserted into the side wall of the kiln 1 without distinguishing between front and rear ends, making it more convenient to use. Therefore, it is necessary to provide a second anchor hole 25 at both ends of the brick body 2 so that both ends can be hooked with the anchoring device 3.

[0032] As an optional implementation method, such as Figure 4 As shown, the brick body 2 includes a first brick 23 and a second brick 24. The first brick 23 and the second brick 24 are respectively provided with interlocking structures 26 to be assembled into the brick body 2. In this way, the weight of a single brick is 1 / 2 of the weight of the whole brick, which can reduce the weight of a single brick and make it easier for workers to operate. For example, the interlocking structure 26 is a matching concave-convex structure to ensure that the first brick 23 and the second brick 24 are precisely aligned during installation.

[0033] Optionally, such as Figure 1As shown, the side wall of the kiln 1 is provided with a nozzle brick mounting groove 103. A first brick 23 is placed inside the nozzle brick mounting groove 103, and a second brick 24 is placed outside the first brick 23 along the extension direction of the nozzle brick mounting groove 103. In this way, the outer second brick 24 can abut against the first brick 23, and only the second brick 24 needs to be anchored. A second anchor hole 25 is also required on the inner side of the first brick 23 facing the second brick 24 to facilitate pulling out the first brick 23. Of course, in other embodiments, the first brick 23 and the second brick 24 can also be arranged along the extension direction of the nozzle brick mounting groove 103. In this way, the first brick 23 and the second brick 24 can be connected and fixed by a snap-fit ​​structure 26, or two anchoring devices 3 can be set to connect the first brick 23 and the second brick 24 respectively.

[0034] As an optional implementation method, such as Figure 1 As shown, the anchoring device 3 includes an anchor rod 31, a column 33, and a connecting block 32. The column 33 is vertically installed and its height is lower than the lowest point of the brick 2. The connecting block 32 is installed on the top of the column 33. The connecting block 32 is provided with a first anchor hole, and the brick 2 is provided with a second anchor hole 25. One end of the anchor rod 31 is hooked to the first anchor hole, and the other end is hooked to the second anchor hole 25. The hooking method makes it easier to install and disassemble. The anchor rod 31 abuts against the brick in an upward oblique direction to prevent the brick from slipping out.

[0035] Optionally, such as Figure 5 As shown, the anchor rod 31 includes a first anchor hook 311, a second anchor hook 312, and a threaded sleeve 313. The two ends of the threaded sleeve 313 are respectively provided with internal threads in opposite directions. One end of the first anchor hook 311 and the second anchor hook 312 is provided with an external thread that matches the internal thread, and the other end is provided with a first hooking part 3111. The length of the anchor rod 31 can be adjusted by rotating the threaded sleeve 313, thereby fixing and adjusting the position of the brick 2. In use, the brick 2 is first installed into the nozzle brick mounting groove 103, then the anchor rod 31 is installed, the first anchor hook 311 is hooked with the first anchor hole, the second anchor hook 312 is hooked with the second anchor hole 25, and finally the threaded sleeve 313 is rotated to adjust the position of the brick 2.

[0036] Optionally, such as Figure 6 As shown, the anchoring device 3 also includes a hook 34. One end of the hook 34 is provided with a second hook part 341 that hooks into the second anchor hole 25, and the other end is provided with a handle 342. The brick 2 can be easily pulled out by the hook 34.

[0037] This disclosure also provides a kiln 1, including: the above-mentioned nozzle brick assembly, wherein one end of the outer side of the brick body 2 is installed on the side wall of the kiln 1 at an angle downward, which makes it easier to remove the brick body 2 and facilitates the replacement of the nozzle brick.

[0038] Optionally, such as Figure 2As shown, the kiln 1 also includes a combustion gun. The side wall of the kiln 1 is provided with a nozzle brick mounting groove 103 that is inclined upward from the outside to the inside, a combustion gun mounting position 101 that is connected to and located above the nozzle brick mounting groove 103, and a flame nozzle 102 that is connected to and located below the nozzle brick mounting groove 103. The combustion gun is installed on the combustion gun mounting position 101 and connected to the mounting hole 21. The combustion gun ejects atomized heavy oil or natural gas into the mixing channel 22, mixes with the combustion air, ignites, and is ejected from the flame nozzle 102 into the kiln 1. When replacing the brick 2, the combustion gun needs to be removed first, and then installed again when the brick 2 is replaced. After the combustion gun is removed, the side of the brick 2 facing the combustion gun mounting position 101 and the end extending out of the kiln 1 can be used as an operating space, which makes operation easier.
