Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention is applicable to powder and granule transportation equipment, such as vibrations, elbows, tees, pumps, blowing basins, and cyclones in dust collection, slurry transportation, sludge water, pneumatic transportation lines, etc. , relates to a lining laminate applied to parts such as tanks where severe wear occurs.

Conventional technology and its problems Rubber, cement, wear-resistant cast iron, etc. are used as the above-mentioned lining materials, but none of them are optimal in terms of durability, vehicle volume, workability, price, etc. .

Therefore, recently, tile-shaped ceramics have been attracting attention as a material that satisfies each of the above points.

A method of lining the inner surface of a vibrator or the like with ceramic is to directly adhere the ceramic to the inner surface of the vibrator or the like using an adhesive, but this method has the following problems. First, ceramics cannot be pasted in recessed areas such as vibrators that are out of reach.
Poor workability. Second, since the contact area between the ceramic and the vibrator is small, the adhesive strength of the ceramic is weak. Third, if a pipe or the like corrodes, the ceramic easily peels off.

An object of the present invention is to provide a laminate for lining a powder transport device, etc., which solves all of the above-mentioned problems.

Means for Solving the Problems The laminate for lining of powder and granular material transport equipment, etc. according to the present invention has an outer surface that is similar to the lining of powder and granular material transport equipment, etc.
It is provided with an outer layer formed in such a shape and made of a synthetic resin at a portion where it should be T, and an inner layer which covers the inner surface of the outer layer and is made of a large number of tile-shaped wear-resistant materials.

Tile refers not only to flat tiles, but also includes thicker tiles, such as short columnar tiles, and similar tiles.

Embodiments Next, embodiments of the present invention will be described in detail with reference to the drawings.

As shown in Fig. 1, a laminate for lining materials such as powder and granular material transportation equipment has an outer layer (12) made of a synthetic resin (11), and an inner surface of the outer layer (12) covered with a wear-resistant material (13). and an inner layer (14). Synthetic resin (11)
Epoxy-based materials are most suitable, but the material is not necessarily limited thereto. Furthermore, if the laminate requires strength, glass fibers (not shown) may be embedded in the synthetic resin (11). The wear-resistant material (13) is made of ceramic whose main component is a metal oxide such as aluminum oxide, and has a square size of 2 cm x 2 cm.
It is formed into a tile shape with a thickness of about 4 mm. Both the inner and outer peripheral surfaces of the wear-resistant material (13) are chamfered (15).
is applied.

Figures 4 to 7 show the above-mentioned outer layer (12) and inner FJ.
(14) and shows the appearance of laminates having various shapes. In other words, in Fig. 4, the plate-like object is shown, and in Fig. 5, the object is cross-sectionally shaped.
FIG. 6 shows a gutter-like structure with a U-shaped cross section, and FIG. 7 shows a hopper-like structure. The shape of the laminate is not limited to those shown in FIGS. 4 to 7, and the shape of the laminate is determined in accordance with the shape of the part to be lined, such as equipment for transporting powder or granular materials (not shown). . The outer surface of the outer layer <12) of the laminate thus formed into a predetermined shape has a shape corresponding to the portion to be lined as described above. Attachment of the laminate to the same part is selected as appropriate, such as by pasting the laminate to the same part with an adhesive, or by means of rescue tightening such as bolts and nuts.

FIGS. 2 and 3 show modifications of the wear-resistant material. The wear-resistant material (16) shown in Fig. 2 does not have the above-mentioned tile shape, but has a short column shape, and its outer peripheral surface has a tapered part (17 ) is provided. The synthetic resin (11) is packed tightly between the tapered portions (17) of adjacent wear-resistant materials (16), thereby preventing the wear-resistant materials (16) from moving in the lateral direction. ing. The wear-resistant material (18) shown in Figure 3 has a shape and has a tapered part (18) on the outer peripheral surface, as in Figure 2^.
19), and an annular groove (20) is further formed in the tapered portion (19), so that the portion outside the annular groove (20) forms a removal prevention protrusion (21). A stop projection (21) prevents the wear-resistant material (18) from being pulled out from the synthetic resin (11), that is, prevents it from moving inward.

Next, a method for manufacturing the laminate will be described with reference to FIG. Here, we will explain a method for manufacturing the gutter-shaped laminate shown in FIG. 6 using the tile-shaped wear-resistant material (13), but there are also cases where column-shaped wear-resistant materials (16) (18) are used, Needless to say, the same applies to the case of manufacturing a laminated body having a rectangular shape other than the sixth example.

A mold (22) is used for manufacturing the laminate.

The mold (22) has a gutter-like shape similar to the gutter-shaped laminate produced thereby, and its outer peripheral surface is similar to the layer (14) of the same laminated body.
It matches the inner peripheral surface of.

First, a large number of wear-resistant materials (13) are attached to the outer surface of the mold (22) so as to cover it.
! 4. Place the wear material (13) on the double-sided adhesive sheet (23) in advance.
) on one side, and the adhesive sheet = 1 to (23)
The wear-resistant material (13) is attached to the outer surface of the mold (22) through the abrasion resistant material (13). Next, synthetic resin (11) is applied or sprayed onto the joints and outer surface of each wear-resistant material (13). Then, as the synthetic resin (11) hardens, the wear-resistant material (13) and the synthetic resin (11) are integrated, and the integrated wear-resistant material (13) and synthetic resin are separated from the mold (22). A laminate is obtained by molding. Hot air or the like may be used to cure the synthetic resin (11).

Effects of the Invention According to the present invention, since the outer surface of the outer layer is formed in a shape similar to that of a part to be lined in powder and granular material transport equipment, the laminate can be easily applied to the same part as a lining material. Since the synthetic resin and wear-resistant material are integrated, the wear-resistant material will not peel off unless the synthetic resin is destroyed, and the presence of the synthetic resin outer layer will prevent corrosion of the parts that should be lined. can be prevented.
