Description

Technical Field

[0001] This utility model belongs to the technical field of kiln refractory materials, and in particular relates to heat-insulating refractory bricks for the walls of high-strength tunnel kilns. Background Technology

[0002] A tunnel kiln is a continuous high-temperature heating device widely used in the firing of products in industries such as ceramics, refractory materials, and building materials. Its structure resembles a long, narrow tunnel. Products enter from one end on a kiln car, are preheated, fired, and cooled, and then exit from the other end. It has advantages such as high output, low energy consumption, and high degree of automation. The insulating refractory bricks in the walls are the key materials for constructing the core structure of the tunnel kiln. The refractory heating surface directly faces the high-temperature flames and materials inside the kiln and needs to withstand extremely high temperatures, chemical erosion, and airflow scouring. Its function is to ensure the structural strength and stability of the kiln body at high temperatures. The insulating surface is located on the outside of the refractory brick plate. Its function is to effectively prevent heat loss from inside the kiln to the outside of the kiln body, reduce the surface temperature of the kiln wall, thereby significantly improving energy utilization efficiency and improving the working environment. Traditional wall structures usually build the refractory layer and the insulating layer into a whole or tightly bond them together with adhesives to form the inner lining of the kiln.

[0003] The existing high-strength tunnel kiln wall insulation refractory bricks still have some problems during use. For example, the refractory heating surface of the tunnel kiln is easily damaged due to long-term direct contact with high temperature, such as cracking, peeling, and erosion. However, the internal insulation bricks usually remain intact when they are not in direct contact with the flame. When a local or small number of refractory heating surfaces are damaged, because they are fixed to the insulation layer and even the entire kiln structure, or are integrally constructed, repair and replacement are extremely inconvenient. Existing maintenance methods often require the removal and replacement of a large area, or even the entire surface, of the refractory layer and insulation layer. This not only wastes a lot of usable insulation material and increases production costs, but more seriously, it requires the kiln to be shut down for a long time. The maintenance workload is large and the cycle is long, which seriously affects production efficiency and equipment utilization.

[0004] To address these issues, we provide high-strength refractory bricks for the walls of tunnel kilns. Utility Model Content

[0005] The purpose of this invention is to provide high-strength wall insulation refractory bricks for tunnel kilns. Through the cooperation of the installation mechanism and the refractory brick mechanism, the invention solves the problem that the existing wall insulation refractory bricks are extremely inconvenient to repair and replace, requiring the removal of a large area, or even the entire surface, of the refractory layer and insulation layer before replacement.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to heat-insulating refractory bricks for the walls of high-strength tunnel kilns. The tunnel kiln includes an installation mechanism inside, and a refractory brick mechanism inside the installation mechanism. The installation mechanism includes a fixing plate fixedly connected inside the tunnel kiln, a limiting component inside the fixing plate, and an anti-detachment component on one side of the fixing plate. The refractory brick mechanism includes a heat-insulating brick plate on one side of the fixing plate, a refractory brick plate on one side of the heat-insulating brick plate, and a partition plate between the heat-insulating brick plate and the refractory brick plate.

[0008] The present invention is further configured such that the limiting component includes limiting plates disposed at the top and bottom of the refractory brick mechanism, and limiting grooves formed on the surface of the fixing plate and the refractory brick plate.

[0009] The present invention is further configured such that the anti-detachment component includes a side baffle fixedly connected to one side of the fixed plate, and a front baffle disposed on the front side of the refractory brick plate.

[0010] The present invention is further configured such that an anti-detachment groove is provided on the front side of the refractory brick plate, and an installation screw is threadedly connected to one side of the fixing plate.

[0011] The present invention is further configured such that both the heat-insulating brick plate and the fire-resistant brick plate have anti-movement grooves adapted to the partition plate on one side, and the width of the partition plate is greater than the depth of the two anti-movement grooves.

[0012] The present invention is further configured such that the partition plate has an abutting groove on the side near the refractory brick plate, and the two abutting grooves are arranged as a group on the top and bottom of the partition plate.

[0013] The present invention has the following beneficial effects.

[0014] 1. This utility model achieves modular installation and disassembly of the refractory brick mechanism through a sliding locking mechanism consisting of a limiting plate, a limiting groove, a front baffle, and an anti-detachment groove. The pre-assembled refractory brick mechanism is pushed into the mounting base consisting of a fixing plate, and the front baffle and the anti-detachment groove cooperate to achieve forward positioning. Then, the limiting plate is pushed in to complete vertical pressing, and finally, the mounting screws are used to tighten it. This process transforms the traditional masonry or adhesive fixing into a mechanical quick-installation structure. When replacing locally damaged refractory bricks, it is not necessary to damage the surrounding overall structure. The damaged module can be replaced individually by simply reversing the operation, which greatly shortens the maintenance time, reduces material waste and production losses caused by downtime, and effectively improves maintenance efficiency.

[0015] 2. This utility model achieves quick installation and replacement while ensuring the stability and reliability of the overall structure under high-temperature conditions through the lateral interlocking of the anti-movement groove and the partition plate, and the longitudinal cooperation of the limiting plate and the abutting groove. The partition plate is embedded in the anti-movement groove of the heat insulation brick plate and the fire refractory brick plate to restrict lateral displacement, while the end of the pushed-in limiting plate is inserted into the abutting groove to lock the partition plate and provide clamping force. In addition, the width of the partition plate is greater than the depth of the groove, which provides buffer space for thermal expansion. This multi-directional limiting design allows the components to maintain a stable connection under thermal stress, effectively preventing the bricks from loosening or misaligning due to thermal expansion or airflow scouring, and extending the overall service life of the lining.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Please see Figures 1-5 This utility model relates to a high-strength tunnel kiln wall insulation refractory brick, comprising a tunnel kiln 1, an installation mechanism 2 inside the tunnel kiln 1, and a refractory brick mechanism 3 inside the installation mechanism 2. The installation mechanism 2 includes a fixing plate 21 fixedly connected inside the tunnel kiln 1, a limiting component 22 disposed inside the fixing plate 21, and an anti-detachment component 23 disposed on one side of the fixing plate 21. The refractory brick mechanism 3 includes an insulation brick plate 31 disposed on one side of the fixing plate 21, a refractory brick plate 32 disposed on one side of the insulation brick plate 31, and a partition plate 33 disposed between the insulation brick plate 31 and the refractory brick plate 32.

[0027] Specifically, the core function of the installation mechanism 2 is to provide a modular, detachable fixed frame and a precise limiting system for the refractory brick mechanism 3. The fixing plate 21 is fixed to the kiln body as the basic load-bearing structure. The limiting component 22 provides a vertical sliding slot and precise positioning, and the anti-detachment component 23 forms constraints from the side and front. Together, they form an installation base that allows the refractory brick mechanism 3 to slide in, be positioned and locked, either as a whole or in part. Through the setting of the refractory brick mechanism 3, the traditional integral masonry structure is decomposed into three independent components: the heat insulation brick plate 31, the refractory brick plate 32 and the partition plate 33. The components are interlocked laterally through the cooperation of the anti-movement groove 6 and the partition plate 33, and are fixed longitudinally through the cooperation of the abutting groove 7 and the limiting plate 221. This facilitates the quick replacement of the heat insulation brick plate 31 or the refractory brick plate 32 when needed.

[0028] Example 2

[0029] Please see Figures 1-5 Based on Embodiment 1, the limiting component 22 includes limiting plates 221 disposed at the top and bottom of the refractory brick mechanism 3, and limiting grooves 222 formed on the surfaces of the fixing plate 21 and the refractory brick plate 32. Both the limiting plate 221 and the limiting groove 222 are convex in shape. The anti-detachment component 23 includes a side baffle 231 fixedly connected to one side of the fixing plate 21, and a front baffle 232 disposed on the front side of the refractory brick plate 32. The front baffle 232 is fixedly connected to the limiting plate 221. An anti-detachment groove 4 is formed on the front side of the refractory brick plate 32. The anti-detachment groove 4 and the limiting plate 221 are fixedly connected. The front baffle 232 is compatible with the mounting plate 21, which is threaded with a mounting screw 5 on one side. The mounting plate 21 and the limiting plate 221 are both provided with mounting through holes that are compatible with the mounting screw 5. The heat insulation brick plate 31 and the fire refractory brick plate 32 are both provided with anti-movement grooves 6 that are compatible with the partition plate 33 on one side. The width of the partition plate 33 is greater than the depth of the two anti-movement grooves 6. The partition plate 33 is provided with abutting grooves 7 on the side near the fire refractory brick plate 32. Two abutting grooves 7 are set as a group at the top and bottom of the partition plate 33. The limiting plate 221 is compatible with the abutting grooves 7.

[0030] Specifically: the limiting component 22 is used to limit the refractory brick plate 32 inside the fixing plate 21; the side baffle 231 limits the sides of the heat insulation brick plate 31 and the refractory brick plate 32; the front baffle 232 limits the front of the refractory brick plate 32; the anti-detachment groove 4 limits the front of the refractory brick plate 32 to prevent it from moving forward; and the mounting screw 5, after the refractory brick mechanism 3 is assembled, fixes the limiting plate 221 to the fixing plate 21, thus completing the refractory brick mechanism. The fixed installation of plate 33, through the setting of anti-movement groove 6, enables the partition plate 33 to limit the heat insulation brick plate 31 and the fire refractory brick plate 32, preventing lateral displacement of the heat insulation brick plate 31 and the fire refractory brick plate 32 after installation. The design of the width being greater than the depth of the two anti-movement grooves 6 creates a certain gap between the heat insulation brick plate 31 and the fire refractory brick plate 32, leaving space for thermal expansion. Through the setting of the abutting groove 7, when the limiting plate 221 is pushed backward, the limiting plate 221 inserts into the abutting groove 7 to limit the partition plate 33 and prevent the partition plate 33 from shifting.

[0031] The working principle of this utility model is as follows: During initial installation, the pre-assembled refractory brick mechanism 3 is slid into the frame of the installation mechanism 2 along the fixed plate 21 as a whole module. During this process, the side baffles 231 constrain the lateral movement of the refractory brick mechanism 3 from both sides to ensure that it moves in a straight line.

[0032] After the module slides to the final working position, the limiting plate 221 is pushed to slide along the limiting groove 222, so that the front baffle 232 slides into the anti-detachment groove 4 on the front side of the refractory brick plate 32. At the same time, the rear end of the limiting plate 221 will be inserted into the abutting grooves 7 opened at the top and bottom of the partition plate 33, thereby simultaneously completing the longitudinal limiting of the partition plate 33 and the vertical pressing of the entire refractory brick mechanism 3. Finally, the mounting screw 5 is passed through the mounting through holes on the fixing plate 21 and the limiting plate 221 and tightened to firmly fix the limiting plate 221 on the fixing plate 21, thus completing the entire installation and fixing process.

[0033] When disassembling and replacing damaged parts, simply follow the reverse order: loosen and remove the mounting screw 5, pull out the limiting plate 221, and the entire refractory brick mechanism 3 module or a single refractory brick plate 32 can be slid out from the front for replacement, achieving efficient and precise maintenance.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
