Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of ceramic tile production equipment, and in particular to an arc-shaped tile pad. Background Technology
[0002] Ceramic liners are made primarily of alumina (AL2O3), with other additives, and sintered at a high temperature of 1700℃. They are widely used in coal conveying, material conveying, pulverizing, ash removal, and dust removal systems in enterprises such as thermal power, steel, smelting, machinery, coal, mining, chemical, cement, and port terminals. Different types of products can be selected according to different needs. Some circular equipment will be covered with a protective layer, which is made of arc-shaped inner lining plates spliced together. The arc-shaped inner lining plates are made of ceramic material. The protective layer can protect the inner wall of the circular equipment from damage. The ceramic lining plate is a ceramic tile with an arc shape. Before sintering, the ceramic tile is divided into sections using steel molds, dry-pressed and sintered, and then ground and spliced into a cylindrical shape.
[0003] When ceramic curved tile blanks are stacked on a sintering platform, the following problems arise:
[0004] 1. During the firing process of tile-shaped clay blanks in the kiln, the placement method (such as standing upright, placing with the arc facing upwards or downwards) will cause deformation due to "shrinkage" and high-temperature softening and deformation, resulting in the ceramics not meeting the standard size after firing. At the same time, because the stacked clay blanks shrink simultaneously during firing, the yield of curved ceramic tiles is low.
[0005] 2. After sintering, ceramic tiles require extensive polishing to meet the requirements of the drawings, resulting in high production costs and a low pass rate. Utility Model Content
[0006] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.
[0007] Specifically, the technical problem to be solved by this utility model is to provide an arc-shaped tile-shaped pad to solve the current problems of large overall cost of ceramic lining, deformation of tile-shaped clay blanks during sintering, and the need for polishing of sintered ceramic tiles to meet the product standards in the drawings.
[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution:
[0009] An arc-shaped tile-like pad includes a metal pad frame, on which an arc-shaped tile sintering support mechanism is fixedly installed, and on the top of the metal pad frame is an extension mechanism.
[0010] The arc-shaped tile sintering support mechanism includes a support pad frame, with a first locking strip fixedly installed at the bottom of the support pad frame, second locking strips fixedly installed on both sides of the support pad frame, and a metal arc-shaped pad head fixedly installed at the top of the support pad frame.
[0011] As an improved technical solution, the top of the metal pad is provided with a slot, and the inner surface of the slot engages with the outer surface of the first card strip.
[0012] As an improved technical solution, the extension mechanism includes an extension rod, a locking block is fixedly installed at the bottom of the extension rod, and a sliding groove is provided on the opposite side of the two extension rods.
[0013] As an improved technical solution, the inner surface of the groove is slidably connected to the outer surface of the second card strip.
[0014] As an improved technical solution, the extension mechanism further includes a fixing groove, which is opened at the top of the extension rod and the top of the metal pad, and the inner surface of the fixing groove is engaged with the outer surface of the locking block.
[0015] As an improved technical solution, the top of the metal arc-shaped pad is provided with a ceramic tile blank.
[0016] After adopting the above technical solution, the beneficial effects of this utility model are:
[0017] 1. This utility model improves the design of ceramic tile blanks by adding a sintering and shaping process. Through the combined use of metal pads, support pads, and metal arc-shaped pads, the metal arc-shaped pads work in conjunction with the ceramic tile blanks. This ensures that the force of the ceramic tile blanks is uniformly received by the metal pads during sintering, softening, and shrinking. Therefore, the product cannot deform when softening at high temperatures. This avoids the problem of high production costs and low pass rates caused by the need for extensive grinding of sintered ceramic tiles to meet the requirements of the drawings. Furthermore, the support pads are used in conjunction with the No. 1 clip and the slot, allowing for the replacement of metal arc-shaped pads with correspondingly customized arcs according to the curvature of the ceramic tile blanks.
[0018] 2. This utility model adds a design to maintain a consistent curvature for all sintered ceramic tile blanks. Through the cooperation of extension rods and metal pads with clips and fixing grooves, multiple support pads are vertically overlapped on the extension rods. This ensures that only one layer of ceramic tile blank is placed on each metal arc-shaped pad, preventing the ceramic tile blanks from being stacked and sintered, which would cause them to soften and stick together. This avoids the problem of having to pry apart and grind the stuck ceramic tiles after sintering, thus improving the yield of sintered ceramic tiles and reducing the manufacturing cost of arc-shaped ceramic tiles.

[0030] like Figure 1 and Figure 4 As shown in the figure, this embodiment provides an arc-shaped tile-shaped pad, which includes a metal pad frame 1, an arc-shaped tile sintering support mechanism 2 fixedly installed on the metal pad frame 1, and an extension mechanism 3 fixedly installed on the top of the metal pad frame 1.
[0031] The arc-shaped tile sintering support mechanism 2 includes a support pad frame 21. A first-order clip 22 is fixedly installed at the bottom of the support pad frame 21, and a second-order clip 23 is fixedly installed on both sides of the support pad frame 21. A metal arc-shaped pad head 24 is fixedly installed at the top of the support pad frame 21.
[0032] The metal pad 1, support pad 21, first clamping strip 22, second clamping strip 23, and metal arc-shaped pad 24 are all made of titanium alloy. Titanium alloy costs around 600 yuan per kilogram, resulting in low-cost equipment. Furthermore, titanium alloy is a high-strength, low-density metal material with excellent high-temperature resistance. Its melting point is as high as 1688°C, and its boiling point reaches 3287°C, demonstrating its superior high-temperature tolerance. In addition, titanium alloy also has excellent fatigue resistance, corrosion resistance, and low thermal conductivity. The curvature of the metal arc-shaped pad 24 matches the curvature of the ceramic tile blank 5. By changing the support pad 21, metal arc-shaped pads 24 with different curvatures can be fixed to the metal pad 1, ensuring that ceramic tile blanks 5 with different curvatures have corresponding metal arc-shaped pads 24.
[0033] like Figure 1 and Figure 4 As shown, the top of the metal pad 1 is provided with a slot 4, and the inner surface of the slot 4 is engaged with the outer surface of the first card strip 22.
[0034] The support pad 21 can be fixed to the metal pad 1 by the first clip 22.
[0035] like Figure 1 and Figure 3 As shown, the extension mechanism 3 includes an extension rod 31, a locking block 32 is fixedly installed at the bottom of the extension rod 31, and a sliding groove 33 is provided on the opposite side of the two extension rods 31.
[0036] Both the extension rod 31 and the locking block 32 are made of titanium alloy.
[0037] like Figure 1 and Figure 3 As shown, the inner surface of the slide groove 33 is slidably connected to the outer surface of the second card strip 23.
[0038] The support pad 21 can be fixed inside the extension rod 31 by means of the second clip 23.
[0039] like Figure 1 , Figure 2 and Figure 3 As shown, the extension mechanism 3 also includes a fixing groove 34, which is opened on the top of the extension rod 31 and the top of the metal pad 1. The inner surface of the fixing groove 34 is engaged with the outer surface of the locking block 32.
[0040] The cooperation between the fixing slot 34 and the locking block 32 allows multiple extension rods 31 to be assembled into a whole and fixed to the metal pad 1.
[0041] like Figure 1 As shown, the top of the metal arc-shaped pad 24 is provided with a ceramic tile blank 5.
[0042] Ceramic tile blank 5 is a clay blank made of alumina (AL2O3) as the main material. After being sintered at high temperature, it becomes a ceramic tile.
[0043] In use, the user first assembles the multiple extension rods 31. First, the locking block 32 at the bottom of one extension rod 31 is inserted into the fixing groove 34 at the top of another extension rod 31, assembling the multiple extension rods 31 into a single unit. Then, the locking block 32 at the bottom of the assembled extension rod 31 is inserted into the fixing groove 34 above the metal pad 1. Next, the support pad 21 is placed on the metal pad 1, with the first locking strip 22 of the support pad 21 engaging in the locking groove 4, and the second locking strip 23 engaging in the sliding groove 33, thus placing the support pad 21 onto the metal pad 1. Simultaneously, multiple support pads 21 are placed onto the extension rods 31, with the second locking strip 23 of the support pad 21 engaging... Within the groove 33 of the extension rod 31, multiple support pads 21 with metal arc-shaped pads 24 are positioned above the metal pad 1. The processed ceramic tile blanks 5 are then placed on the metal arc-shaped pads 24. After all the ceramic tile blanks 5 are placed on the metal arc-shaped pads 24, the metal pad 1 is placed in a high-temperature furnace for sintering. During sintering, the ceramic tile blanks 5 soften and shrink. After softening, they adhere tightly to the metal arc-shaped pads 24, ensuring that the arc-shaped top of the metal arc-shaped pads 24 maintains the curvature of the ceramic tile blanks 5. Simultaneously, the stress generated when the ceramic tile blanks 5 shrink can be evenly applied to the top of the metal arc-shaped pads 24, thus preventing the product from deforming during high-temperature softening.
[0044] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
