Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an exchanger such as a rotary heat exchanger formed of a substrate with low rigidity such as asbestos, and a method for manufacturing the same.

Generally, as shown in FIG. 1, the rotary heat exchanger E is disposed so as to span two flow paths, and is used so that heat exchange is performed between the air flows S1 and S2 flowing in these flow paths.

In order to prevent the airflows S1 and S2 from leaking from these channels, a sealing material Se is generally attached to the frame F, and the rotary heat exchanger E is equipped with a sealing material Se.
The contact portions (both end surfaces) in contact with e slide on the sealing material Se as it rotates.

Therefore, if the rotary heat exchanger is made of non-metallic materials such as asbestos, the rigidity and wear resistance will be low, and the contact parts will wear out due to sliding with the sealing material Se, causing dust generation. Another problem is that they are easily damaged and become unusable.

Therefore, an object of the present invention is to provide an exchanger such as a rotary heat exchanger that solves this problem.

Below, an example in which the present invention is implemented in a rotary heat exchanger will be described in detail together with a manufacturing method.

Figures 3A and 3B are a front view and a top view schematically showing a manufacturing apparatus for carrying out the manufacturing method in an embodiment of the present invention, and Figures 4A, B, and C show the same manufacturing process. 5A and 5B are cross-sectional views showing a base material provided with a protective coating and other embodiments.

A base material 1 made of a strip of asbestos material wound into a roll is unwound and fed in the direction D, and on both sides of the unwound base material 1, a strip of asbestos material wound in a roll is unrolled and fed in the direction D. The protection piece 2 made of aluminum is unwound and fed in the direction D via the guide G1.

As shown in FIG. 4A, the guide G1 causes the protective piece 2 to abut perpendicularly on both sides of the base material, and in this abutting state, the protective piece 2 is moved together with the base material 1 in the direction D.

Eventually, the protective piece 2 reaches the first-stage forming roll 3, where it is bent by a pressing force against the base material 1, and then moves along the guide G2.

Note that G3 is a guide roller that serves to prevent the base material 1 from deforming up and down when the protective piece is pressed against the base material 1 side by the forming roll 3.

In this way, the protective piece 2 is attached to the base material 1 as shown in FIG. 4B.
The base material 1 moves together with the base material 1 while remaining in contact with the base material 1 at an acute angle on both sides.

Moving in this way, the protective piece 2 and the base material 1 are pressed from above and below by the pressing roll 4, and the protective piece 2 is pressed tightly against both sides of the base material 1, as shown in FIGS. 4C and 5A. As shown, a protective covering part 2' is provided to cover both sides of the base material 1 with protective pieces 2.

Note that the state in which the protective covering portion 2' covers both sides of the base material is not limited to the above, but includes the state shown in FIG.
Furthermore, it goes without saying that it can be made into various forms.

The base material 1 provided with the protective covering portion 2' in this manner becomes a rotary heat exchanger through the following molding process.

That is, after being formed into a wavy shape by passing between forming rolls whose outer circumferential surfaces are formed into a wavy shape, the strip 6 made of a strip of asbestos paper wound around the roll is fed and overlapped with the strip 6. The rotary heat exchanger 7 is wound in a spiral shape as a whole to form a honeycomb shape.

This rotary heat exchanger 7 has the above-mentioned protective covering portions 2' formed on both end faces thereof.

Note that it is of course possible to provide a protective coating made of aluminum or the like on both sides of the strip 6 in the same manner as the base material 1, and the base material 1 can be attached to the base material 1 by adhesive means.
It is also possible to bond the protective covering 2' to the aluminum or the like of the strip 6.

Therefore, when this rotary heat exchanger 7 is used in a generally used manner, for example, the manner shown in FIGS.
Since both end faces of the rotary heat exchanger 7 are coated with protective coatings 2', the rotary heat exchanger 7 slides on the sealing material Se as it rotates, but is hardly subject to wear or damage.

The present invention has been described above using an exchanger for heat exchange as an example, but is not limited to this, and may be applied to an exchanger having a moisture exchange function depending on the base material, strip, etc. Can be implemented.

According to the present invention, since an exchanger such as a rotary heat exchanger is coated with a protective member on both sides of the base material, there is almost no wear or damage even when sliding on a sealing material, etc., and the base material As a material with low rigidity, such as asbestos, can be used, which simplifies the construction.However, in this case, it generates almost no dust during use, which helps prevent asbestos pollution, and prevents it from becoming unusable due to damage. Moreover, in terms of manufacturing, since the base material provided with the protective coating is subjected to the process for molding, there are no countermeasures against unexpected deformation during molding, destruction due to insufficient strength, etc. It has many practical advantages, such as ease of management.
