[0001] The utility model relates to the technical field of iron-making blast furnaces, in particular to a wear-resistant and anti-falling ceramic lining plate for a material discharge chute of an iron-making blast furnace. Background Art

[0002] A blast furnace is a device used to produce pig iron. During the use of the unloading chute of the blast furnace, a ceramic lining needs to be laid on its inner wall.

[0003] After searching, the patent number is CN213207246U, and the name is a utility model of a ceramic composite lining, including a substrate and a ceramic block. Through research and analysis, it is found that although its overall density is greatly reduced and its weight is greatly reduced during use, and it can be applied to more and wider occasions, etc., it still has the following disadvantages to a certain extent.

[0004] For example, it does not have an anti-falling function. During the use of the above-mentioned ceramic lining, the bolts cannot be limited and fixed, which causes the bolts used to position the ceramic lining to loosen easily during long-term use, thereby causing the lining to fall off, thereby affecting the use of the unloading chute. In order to solve the above technical problems, we have designed a wear-resistant and anti-falling ceramic lining for the unloading chute of an iron-making blast furnace. Utility Model Content

[0005] The utility model aims to provide a wear-resistant and anti-falling ceramic lining for the unloading chute of an iron-making blast furnace, which has the advantages of anti-falling function and strong wear resistance, and solves the problem that the existing ceramic lining cannot limit and fix the surface of the bolt during use, and the wear resistance of the ceramic surface is poor, and it is easy to wear during long-term use.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wear-resistant and anti-falling ceramic lining for a material chute of an iron-making blast furnace, comprising a lining, a first groove is provided on the front side of the lining, a first bolt is movably connected to the inner cavity of the first groove, a rear end of the first bolt passes through to the rear side of the lining, a second groove is provided at the bottom of the inner cavity of the first bolt, a second bolt is threadedly connected to the inner cavity of the second groove, a slide groove is provided at the bottom of the front side of the first bolt, a slide plate is slidably connected to the inner cavity of the slide groove, a clamping plate is fixedly connected to the inner wall of the first groove, a threaded hole is provided on the front side of the lining, and a wear-resistant mechanism is threadedly connected to the inner cavity of the threaded hole.

[0007] Preferably, the wear-resistant mechanism comprises a threaded rod, a surface of the threaded rod is threadedly connected to a threaded hole, and a wear-resistant protrusion is riveted on the front end of the threaded rod.

[0008] Preferably, limiting grooves are provided at the tops of both sides of the inner cavity of the slide groove, limiting plates are riveted to the tops of both sides of the slide plate, and the opposite sides of the limiting plates extend to the inner cavity of the limiting groove.

[0009] Preferably, a positioning groove is provided on the top of the slide plate, and the bottom end of the second bolt extends to the inner cavity of the positioning groove.

[0010] Preferably, there are several card boards, which are arranged in a surrounding manner.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. The utility model has the advantage of anti-falling function through the cooperation of the first groove, the first bolt, the second groove, the second bolt, the slide, the slide plate and the clamping plate. The liner and the unloading chute are connected and fixed by the first bolt, and then the slide plate is inserted into the inner cavity of the slide, the second bolt is placed in the inner cavity of the second groove, and then the second bolt is tightened to make the bottom end of the second bolt extend to the inner cavity of the positioning groove. At this time, the slide plate is engaged with the clamping plate, so that the first bolt cannot rotate, thereby preventing the liner from falling off.

[0013] 2. The utility model has the advantage of strong wear resistance through the cooperation of the threaded hole and the wear-resistant mechanism. The threaded rod is installed in the inner cavity of the threaded hole, and the material contacts the wear-resistant protrusion during the feeding process, thereby reducing the friction on the lining and improving the service life of the lining.
