Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a furnace, and more particularly to a furnace that uses a furnace cylinder having a corrugated cross-section as a furnace material.

Traditionally, furnaces have been installed in which a furnace tube body with a wave-shaped cross section is fitted around the outer periphery of a core body made of a porous cylindrical body, and both ends are held down by donut plate-shaped end plates. A passing device is used.

However, in the above-mentioned furnace, if the stagnation cylinder becomes clogged, it is necessary to replace it with a new one. There was still not enough in terms of sexual security.

The present invention has been made for the purpose of providing a furnace filtration device that can improve the ease of attaching a filtration bridge to a core body and enhance the sealing effect after installation. All but a few ridges at at least one location on the mounting portions at both ends of the furnace tube are fixed with a hardening resin or the like in a sliding state at a predetermined pitch and in an arc shape that closely contacts the outer circumferential surface of the core. However, elasticity in the circumferential direction is left in the free ridge portions of the several ridges that do not solidify, and when it is applied to the core, it is expanded and lacquered by the expansion of the free ridge portions, and after competition, as necessary. It is characterized by a structure in which a piece of soft packing is interposed in the free space, and the end plate prevents both ends of the furnace tube from coming off and is fixed.

The present invention will be described below with reference to embodiments shown in the drawings.

FIG. 1 shows a longitudinal cross section of an embodiment of the furnace filtration device according to the present invention, and its basic configuration is the same as that of the secondary furnace, including a core body 1 made of a porous cylindrical body; A furnace tube body 2 that is iron-fitted on the outer periphery, and a donut plate-shaped end plate 3 that is iron-fitted to both ends of the core body 1 to fix the furnace tube body 2.
, 3. The furnace tube body 2 is made by bending furnace paper into a corrugated shape and winding it into a cylinder shape, and usually has about 160 ridges in the circumferential direction. It is joined along the outer periphery of 1.

In the present invention, when the furnace tube body 2 is fitted to the core body 1, in a diametrically symmetrical position, the peak portion 2A of the furnace tube body 2 is
, 2A... are brought into a sliding state in which they slide at a predetermined pitch, and are hardened over a required range at both ends of the furnace tube body 2 in an arc shape that matches the arc of the outer peripheral surface of the core body 1. The several peaks of the furnace tube body 2 between the fixed areas 5 and 5 become free peaks 2 in a free state.
B, 2B.

Therefore, the diameter of the furnace cylinder 2 can be expanded at the free peaks 2B, 2B in the free state, and then when aligned with the outer peripheral surface of the core 1, all the peaks 2A, 2
B is formed to be the furnace tube body 2 which is curved at a predetermined pitch.

In the illustrated embodiment, a soft packing piece 6 made of European synthetic resin or the like as shown in FIG. 3 is attached to the outer surface of the free mount 2B in consideration of the sealability of the free mount 2B portion. The soft packing pieces 6 have a wedge-shaped side surface, and when they are adhered alternately to the outer surfaces of the free ridges 28 as shown in the second figure and brought into a sliding state, the soft packing pieces 6 each have a wedge-like shape. As shown in the figure, the ends of the furnace tube body 2 in this area are sealed by coming into close contact with each other. In addition, a packing 7 is also interposed on the outer peripheral surface of the core body 1 at a portion where the fixing regions 5, 5 of the furnace cylinder 2 and the soft packing pieces 6 are placed.

In the figure, 8' is a fixing band. Since the present invention is constructed as described above, when the furnace tube body 2 is iron-fitted to the core body 1, by holding the fixing areas 5, 5 and spreading them out, the peaks of the free mountain-dense portion can be adjusted as shown in the second figure. It can be stretched and expanded as shown in the figure, and can be easily collocated with the core body 1, and then fixed areas 5, 5
If it is brought into close contact with the outer circumferential surface of the core body 1, the peak of the free mountain field portion will shrink, and the European packing pieces 6 glued to the outer surface of the free mountain wave will come into close contact with each other and become in a predetermined sliding state. At the same time, all ends of the furnace cylinder 2 are sealed to ensure that no fluid leaks.

As explained above, according to the present invention, there is no cross-sectional wave shape and it is possible to immediately set a predetermined pitch by simply fitting the furnace tube to the core, so that the pitch of the furnace tube to the core can be immediately set. It is extremely easy to install, and since the fixed area is sealed from the beginning, the only part that requires sealing is the free crest, making it easy to seal, significantly improving assembly and sealing performance. I can do it.
