Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel kilns, in particular to a side wall of an assembled tunnel kiln. Background Art

[0002] A tunnel kiln is a tunnel-like kiln built of refractory materials, thermal insulation materials and building materials, equipped with kiln cars and other vehicles. It is a modern continuous firing thermal equipment. Tunnel kilns are widely used in the roasting production of ceramic products and are also used in metallurgical industries such as abrasives. The design of the side walls of prefabricated tunnel kilns needs to consider multiple factors to ensure their safe, stable and efficient operation. The connection between the side walls, the top arch and the foundation needs to be reasonably designed to ensure the stability and sealing of the entire kiln structure.

[0003] However, in the prior art, the outer wall of the tunnel kiln is mostly constructed by first building a steel structure body, and then using red bricks for on-site masonry, which results in a long construction period. In addition, during normal operation of the kiln, the refractory materials (refractory bricks) expand and squeeze each other tightly due to the high temperature, and the expansion stresses restrain each other to reach a balance. However, after the furnace is shut down, the refractory materials shrink, and a large amount of high-humidity air enters the refractory bricks and is easily sucked into the masonry, causing the bricks to break, thereby affecting the service life and safety performance of the kiln.

[0004] To this end, we provide assembled tunnel kiln side walls to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide an assembled tunnel kiln side wall, which solves the problem in the prior art that the tunnel kiln outer wall is built on site with red bricks, has a long construction period, and does not have a moisture-proof function through the coordinated arrangement of an assembly component and a protection component.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0010] The utility model is further configured that a card slot is provided inside the installation plate, and the size of the card connecting plate is the same as that of the card slot.

[0011] The utility model is further configured such that the height of the heat insulation board is less than the distance between the two sets of guide rail boards, and the size of the metal back plate is the same as that of the fireproof board.

[0016] The utility model can install the metal back plate and the refractory bricks and the refractory bricks separately through the setting of the assembly components.

[0029] The protective component includes a base layer 301, a heat-resistant expansion layer 302 is fixedly connected to the surface of the base layer 301, a durability layer 303 is fixedly connected to the surface of the heat-resistant expansion layer 302, and a moisture-proof layer 304 is coated on the surface of the durability layer 303. The refractory brick 3 consists of a base layer 301, a heat-resistant expansion layer 302, a durability layer 303 and a moisture-proof layer 304.

[0030] Specifically, the metal back plate 1 is used to support the entire wall and facilitate connection with external equipment. The fire-resistant board 2 can effectively isolate the internal and external environments to prevent the external structure from being affected by high temperatures. The insulation board 4 can be used as the lining material of the side wall to protect the exterior wall and other structural materials from high temperatures and chemical corrosion, thereby extending the service life of the side wall. The mounting plate 5 and the clamping plate 6 can be clamped together to facilitate the simultaneous fixing of multiple sets of side wall panels. Specific embodiment 2

[0032] See also Figure 1-4 On the basis of the specific embodiment 1, a card slot 9 is opened inside the mounting plate 5, the size of the card slot 9 is the same as that of the card slot 9, the height of the heat insulation board 4 is less than the spacing between the two sets of guide rail plates 7, the size of the metal back plate 1 is the same as that of the fire-resistant board 2, and a fixing plate 10 is fixedly connected to the rear side of the mounting plate 5, and a fixing bolt 11 is arranged on the rear side of the fixing plate 10, and the front side of the fixing bolt 11 penetrates the fixing plate 10 and is threadedly connected to the metal back plate 1.

The height of the insulation plate 4 is less than the spacing between the two sets of guide rails 7. After the two sets of guide rails 8 are inserted into the guide plate 7, the insulation plate 4 can be inserted into the rear side of the fire-resistant plate 2 to fix the fire-resistant plate 2 and install the insulation plate 4.

Specific embodiment three

[0035] See also Figure 1-4 On the basis of the first and second embodiments, the base layer 301 is made of silicate material, the anti-thermal expansion layer 302 is made of refractory ceramic material, the durability layer 303 is made of high-aluminum refractory material, and the moisture-proof layer 304 is made of aluminum silicate refractory coating.

[0036] Specifically, the base layer 301 is made of silicate material.

The silicate refractory brick 3 has a small thermal expansion coefficient and shrinkage rate, can maintain structural stability, and reduce deformation and damage under high temperature conditions. The anti-thermal expansion layer 302 is made of refractory ceramic material. The refractory ceramic material also usually shows a small shrinkage rate and has good anti-thermal expansion performance. It can reduce the shrinkage effect during the hot and cold cycle process, and at the same time reduce the shrinkage during the kiln operation. In order to solve the problem of cracks and gaps caused by shrinkage caused by hot and cold cycles during operation, the durability layer 303 adopts high-aluminum refractory materials, which usually have a smaller shrinkage rate, can maintain stability at high temperatures, and show good durability during kiln operation. The moisture-proof layer 304 adopts aluminum silicate refractory coating, which has good fire resistance and moisture-proof function, can effectively reduce moisture penetration and improve the moisture resistance of refractory materials. The moisture-proof function of refractory coatings is mainly achieved by controlling the pore structure of the coating and improving the sealing and water resistance of the coating.

[0037] The working principle of the utility model is as follows: the staff moves the fireproof board 2 so that the guide rail 8 on the rear side of the fireproof board 2 fits with the metal back plate 1, and then pushes the fireproof board 2 upward so that the guide rail 8 is inserted into the guide rail plate 7 to achieve the clamping connection between the fireproof board 2 and the metal back plate 1. Figure 2 As shown, the two groups of heat insulation boards 4 are then moved and inserted between the fireproof board 2 and the metal back plate 1, and the fireproof board 2 is limited and fixed by the heat insulation boards 4;

[0038] Repeat the above process to quickly assemble multiple sets of metal back plates 1 and fireproof plates 2, and then move the two assembled metal back plates 1 relative to each other. Figure 3 As shown, the clamping plate 6 is inserted into the mounting plate 5, and then the fixing bolts 11 are inserted into the fixing plate 10 and threadedly fixed to the metal back plate 1, so as to realize the rapid assembly of the side wall panels and increase the construction efficiency;

[0039] At the same time, the base layer 301 is made of silicate material, and the silicate refractory brick 3 has excellent refractory properties and can maintain structural integrity and stability in a high temperature environment. The anti-thermal expansion layer 302 is made of refractory ceramic material, which can reduce the impact during the hot and cold cycle. The durability layer 303 is made of high-aluminum refractory material, which usually has a smaller shrinkage rate and can maintain stability at high temperatures. The moisture-proof layer 304 is made of aluminum silicate refractory coating, which has good refractory properties and moisture-proof functions, can effectively reduce moisture penetration and improve the moisture resistance of the refractory material.
