Description

Technical Field

[0001] This utility model belongs to the field of microcrystalline board technology, and specifically relates to a microcrystalline board for preventing crusting on the inner wall of a cement rotary kiln flue. Background Technology

[0002] The flue chamber of a rotary kiln is a crucial component connecting the kiln and the preheater system. It primarily serves to guide and collect flue gas, separate gas and solids and circulate materials, maintain temperature and pressure balance, and provide structural support and sealing. The flue chamber is the "throat" of the rotary kiln system, directly impacting thermal efficiency, energy consumption, and operational stability. Its design must consider fluid mechanics, material high-temperature resistance, and process compatibility, making it a critical element in cement / metallurgical processes. To improve the rotary kiln's resistance to high-temperature wear, prevent scaling and chemical corrosion, enhance thermal shock resistance, extend service life, and reduce maintenance costs, microcrystalline plates are typically installed inside the flue chamber.

[0003] Traditional microcrystalline panel installation typically involves using castable refractory material or a combination of castable refractory material and a keel support. Using castable refractory material directly eliminates the need for drilling into the microcrystalline panel, thus preserving its surface structure. However, this method suffers from poor stability and a tendency to detach. On the other hand, using castable refractory material with a keel support requires drilling into the microcrystalline panel, which damages its surface structure and reduces its flatness. However, this method offers superior stability. Currently, there is a lack of microcrystalline panels on the market that combine both methods without the need for drilling and while maintaining high stability. Utility Model Content

[0004] The purpose of this utility model is to provide a microcrystalline board for preventing crusting inside the flue gas chamber of a cement rotary kiln, which has the advantages of being hole-free and stable.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a microcrystalline plate for preventing crusting inside the flue gas chamber of a cement rotary kiln, comprising a microcrystalline plate body, a fixing body fixedly connected to the top of the microcrystalline plate body, grooves formed at the four corners of the surface of the fixing body, a connecting block provided inside the groove, a limiting mechanism provided between the connecting block and the groove, and a support groove formed on the connecting block.

[0006] The above technical solution is adopted: the present invention has a support groove on the connecting block. When multiple microcrystalline panels are spliced ​​together, the keel support can be inserted into the support groove to limit and fix the connecting block. Under the action of the limiting mechanism, the fixing body of the microcrystalline panel can be fixed together with the connecting block, thereby fixing the microcrystalline panel on the keel support, improving the stability of the installation, reducing the risk of falling off, and eliminating the need for drilling, thus not damaging the surface structure of the microcrystalline panel.

[0007] The present invention is further configured such that the limiting mechanism includes two limiting grooves formed inside the groove body, and the surface of the connecting block is fixedly connected with a limiting block that engages with the limiting grooves.

[0008] By adopting the above technical solution, the connecting block can be inserted into the groove of the fixed body, and the connecting block and the fixed body can be locked together to prevent separation.

[0009] The present invention is further configured such that sealing blocks are fitted on the two side wall surfaces of the microcrystalline plate, and sealing grooves are formed on the other two side wall surfaces of the microcrystalline plate to engage with the sealing blocks.

[0010] The above technical solution allows for easy interlocking of multiple microcrystalline plates, improving the sealing performance between gaps.

[0011] The present invention is further configured such that both the microcrystalline plate and the fixing body are made of high-alumina microcrystalline plate material.

[0012] The above technical solution improves the wear resistance and high temperature resistance of the microcrystalline plate and the fixing body.

[0013] The present invention is further configured such that the microcrystalline plate and the fixing body have the same size.

[0014] The above technical solution improves the ease of processing.

[0015] In summary, this utility model has the following beneficial effects:

[0016] This invention features a support groove on the connecting block. When multiple microcrystalline panels are spliced ​​together, the keel support can be inserted into the support groove to limit and fix the connecting block. Under the action of the limiting mechanism, the fixing body of the microcrystalline panel can be fixed together with the connecting block, thereby fixing the microcrystalline panel on the keel support, improving the stability of the installation, reducing the risk of falling off, and eliminating the need for drilling, thus not damaging the surface structure of the microcrystalline panel.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Example 1:

[0024] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A microcrystalline board for preventing crusting inside the flue gas chamber of a cement rotary kiln includes a microcrystalline board body 1. A fixing body 2 is fixedly connected to the top of the microcrystalline board body 1. Grooves 3 are formed at the four corners of the surface of the fixing body 2. Connecting blocks 4 are set inside the grooves 3. A limiting mechanism 5 is set between the connecting blocks 4 and the grooves 3. A support groove 6 is formed on the connecting blocks 4. When multiple microcrystalline boards 1 are spliced ​​together, the keel support can be inserted into the support groove 6 to limit and fix the connecting blocks 4. Under the action of the limiting mechanism 5, the fixing body 2 of the microcrystalline board body 1 can be fixed together with the connecting blocks 4, thereby fixing the microcrystalline board body 1 to the keel support, improving the stability of the installation, reducing the risk of falling off, and eliminating the need for drilling, thus not damaging the surface structure of the microcrystalline board body 1.

[0025] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The limiting mechanism 5 includes two limiting grooves 51 opened inside the groove 3. The surface of the connecting block 4 is fixed with a limiting block 52 that engages with the limiting grooves 51. By setting the limiting grooves 51 and the limiting blocks 52, the connecting block 4 can enter the groove 3 of the fixing body 2 and then the connecting block 4 and the fixing body 2 can be locked together to prevent separation.

[0026] refer to Figure 1 The two side walls of the microcrystalline plate 1 are equipped with sealing blocks 7, and the other two side walls of the microcrystalline plate 1 are provided with sealing grooves 8 that engage with the sealing blocks 7. By setting the sealing blocks 7 and sealing grooves 8, multiple microcrystalline plates 1 can be easily engaged together, thereby improving the sealing performance between gaps.

[0027] refer to Figure 1 , Figure 2 and Figure 3 Both the microcrystalline plate 1 and the fixing body 2 are made of high-alumina microcrystalline plate material. By setting both the microcrystalline plate 1 and the fixing body 2 to be made of high-alumina microcrystalline plate material, the wear resistance and high temperature resistance of the microcrystalline plate 1 and the fixing body 2 are improved.

[0028] refer to Figure 1 , Figure 2 and Figure 3 The microcrystalline plate 1 and the fixing body 2 have the same size. By setting the microcrystalline plate 1 and the fixing body 2 to have the same size, the convenience of processing is improved.

[0029] Brief description of the usage process: When multiple microcrystalline panels 1 are spliced ​​and installed, first install the external keel support on the wall of the smoke chamber. Then, the connecting block 4 is inserted into the keel support under the action of the support groove 6. The two can be fixed with bolts. Move the microcrystalline panel 1 to the connecting block 4 so that the groove 3 of the fixing body 2 is locked on the connecting block 4. The limiting mechanism 5 limits the connection block 4 and the fixing body 2 to each other, thereby fixing the microcrystalline panel 1. Then, fill the space between the microcrystalline panel 1 and the smoke chamber wall with castable material to achieve a stable fixation without the need for drilling holes in the microcrystalline panel 1.
