Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a mounting structure for a ceramic liner.

(b) Conventional technology Conventionally, in order to prevent wear that occurs on the surfaces of conveyor belts and pulleys, and on the inner surfaces of hoppers that receive ore, gravel, etc., there have been systems in which a large number of ceramic liners for wear prevention are attached to the surfaces. .

(C) Problems to be Solved by the Invention However, since the ceramic liners attached to such conveyor belts, etc. must accommodate bending at the pulley portion, there are slight gaps between the ceramic liners. The rubber mounting board in the gap was worn out, and the ceramic liner did not have an effective wear effect.

An object of the present invention is to provide a ceramic liner mounting structure that can solve the above problems.

(d) Means for solving the problem The present invention provides a mounting structure for a ceramic liner in which rod-shaped ceramic liners are installed in parallel on the surface of a mounting board. It has an approximately horizontal H-shape consisting of a lower horizontal part and a vertical part that integrally connects both horizontal parts, and the lower horizontal part and the vertical part are buried in the mounting board, and the upper horizontal part is connected to the upper layer. The upper layer is placed in a superposed state on the lower layer of the upper horizontal part of the adjacent ceramic liner, and the upper layer of the upper horizontal part of the adjacent ceramic liner is placed on the lower layer. This invention relates to a mounting structure for a ceramic liner characterized in that layers are placed in a polymerized state.

(E) Effect In this invention, the upper horizontal part of the ceramic liner has a stepped structure consisting of an upper layer and a lower layer. The entire surface of the mounting board is completely covered by placing the ceramic liner in a polymerized state on the lower layer of the ceramic liner, and placing the upper layer of the upper horizontal part of the adjacent ceramic liner on the lower layer in a polymerized state. Can be done.

(F) Effects With the above configuration, the present invention has the following effects.

The upper horizontal part of the ceramic liner has a stepped structure and is connected to the adjacent ceramic in a mutually overlapping state, effectively preventing powder from entering the boundary between ceramic liners even at bent parts such as pulleys. This can prevent damage to the mounting board and prevent wear on the mounting board.

By making the upper horizontal part of the ceramic liner have a stepped structure, the thickness of the upper horizontal part can be increased while ensuring sufficient flexibility of the mounting board, and the heat insulation effect can be improved.

(g) Examples The present invention will be specifically described below based on examples shown in the attached drawings.

In Fig. 1, A indicates a belt conveyor;
The conveyor belt A is an endless conveyor belt 1 wound around a driving pulley 12 and a driven pulley 13.
Consists of 1.

In order to prevent the endless conveyor belt 11 from deflecting, a plurality of guide rollers 11a are interposed between the drive pulley 12 and the driven pulley 13.

A hopper 4 is disposed at one end of the endless conveyor belt 11 for cutting raw materials B such as gravel, various powders, ores onto the conveyor belt 11.

In the configuration of the belt conveyor A, the conveyor belt 11 is preferably made of a rubber mounting board 15 having high strength and flexibility. In order to prevent wear, a plurality of ceramic liners L are installed in a partially buried state.

As shown in FIGS. 2 and 3, each ceramic liner L is disposed in a horizontal direction perpendicular to the running direction of the conveyor belt 1, and there is a gap between adjacent ceramic liners L as will be described later. There are no gaps.

Such ceramic liner L is produced by, for example, mixing 80 to 90% by weight of alumina powder with a particle size of 10 μm or less with 20 to 10% by weight of silica powder, which also has a particle size of 10 μm or less, and forming the mixture into a long length. It can be manufactured by compression molding into a rod shape and sintering the molded body under known sintering conditions.

In the structure for attaching the ceramic liner L to the mounting board 15, the present invention is characterized by the cross-sectional shape of the ceramic liner L and the structure in which the ceramic liner L overlaps with the adjacent ceramic liner L.

That is, as shown in FIG. 4, each ceramic liner L has a cross section consisting of an upper horizontal part 20, a lower horizontal part 21, and a vertical part 22 that integrally connects both horizontal parts 20 and 21. It is approximately horizontally H-shaped.

Further, the ceramic liner L has its lower horizontal portion 21 and vertical portion 22 buried in the mounting substrate, and its upper horizontal portion 20 is buried between the upper layer 20a and the lower layer 20.
It has a stepped structure in which b and b are connected.

With this configuration, each ceramic liner L
The upper layer 20a of the upper horizontal portion 20 of the ceramic liner L is adjacent to the lower layer 20a of the upper horizontal portion 20 of the ceramic liner L.
The mounting substrate 15 is placed on the ceramic liner L in a polymerized state, and the upper layer 20b of the upper horizontal portion 20 of the adjacent ceramic liner L is placed on the lower layer 20b in a polymerized state. This allows the mounting board 15 to be completely covered and prevents wear of the mounting board 15.

In addition, since the ceramic liners L can be mutually bent at the stepped portions, the above-described pulley 14 can easily follow the bending of the pulley 14, and there is no risk of it peeling off from the mounting board 15.

In addition, the upper horizontal part 2 of each ceramic liner L
The end surface a of the upper layer 20a of the ceramic liner L is in contact with the stepped shoulder surface b of the upper horizontal portion 20 of the adjacent ceramic liner L, eliminating the gap between the ceramic liners L and further reducing the wear of the mounting board 15. It can be prevented.

Furthermore, the upper layer 20a of the ceramic liner L
A rubber plate 23 is interposed at the overlapping portion of the lower layer 20b, which can more effectively prevent powder etc. from entering the mounting board 15, and can effectively reduce the impact applied to the ceramic liner L. absorb,
Damage to the ceramic liner L can be prevented.

In the above configuration, the lower horizontal portion 21 of the ceramic liner is buried in the mounting board 15 in a horizontal state, so it functions as an anchor that effectively prevents the ceramic liner L from detaching from the mounting board 15. It turns out.

Moreover, FIGS. 5 and 6 show the ceramic liner L in the form of tiles, which can provide the same effects as the rod-shaped bodies shown in FIGS. 1 to 4.
