Method and device for treating elements passing through a chamber by means of gases

The invention relates to a method for treating Elements, whereby the .zu "treated elements a Can pass through chamber through which gases are passed, their temperature and / or composition in such a way is that this treatment is through their contact with these Elements is ensured.

By the method according to the invention it should be "at the same early reduction of the dimensions of this chamber, especially in the direction of movement of the elements, to obtain a homogeneous and effective treatment of these elements. ^

According to the method of the invention, the elements to be treated are simultaneously a translational and a Rotational movement granted: 'The elements pass through the length of the chamber several times at different levels; one leaves these elements on ρlanen surfaces arranged one above the other, which are transverse

7G9R 1 3 / Π7 £ <3

extend across the chamber, roll, and bring it in Contact with organs that are themselves driven with a continuous translational motion, whereby the same organs successively pass the elements in one direction, then in the other at two different levels.

The elements treated by this process are generally cylindrical, spherical, or ovoid Shape and are driven with a rotational movement around their axis or around their center.

The method according to the invention can be applied to a wide variety of treatment processes such as, for example Drying, hardening, cooling, heating, specifically for processes such as tempering, stress relieving or the like. It can also be applied to covering the surface of elements with substances such as Coatings, paran paints, etc., their composition can be heterogeneous and its components can be effectively mixed due to the motions imparted to these elements will. The method can also be used to create semi-rigid, flexible or peelable elements on the elements to be treated Provide cover layers or coatings.

The elements treated may be tubular in shape, particularly cylindrical tubular shape be. Above all, they can consist of fibrous products and, in particular, fibrous insulating shell bodies in which a binder is distributed between the fibers, those contained in the chamber Gases provide thermal treatment over the entire thickness of the products, with polymerization or the hardening of the binder is made possible. This ar-

articles can be formed, for example, by insulating fibrous shell bodies, in particular of small diameter be, as for example in the German patent application P 25 20 462.0 (corresponding to France 74 17 232 of May 17, 1974 or in DL-PS-AP 119 161 with the title "Process for the continuous production of insulating shell bodies and apparatus for implementation of the method ". According to this, they consist of a felt in which a binding agent is distributed is, these shell bodies have a permeable structure and hardened and smooth inner and outer surfaces own.

The invention also relates to a device for performing this method, the device being formed is through a chamber with at least two perforated floors or plates arranged one above the other, on which the elements to be treated roll and wherein at least one endless chain is provided, which in translational movement is driven and is firmly connected to organs with which the to be treated Elements come into contact, the upper run of this endless chain for the movement of these elements in one Direction above the level of a perforated floor, while its lower run ensures its displacement in the. in the other direction above the other perforated floor, the transition of the elements to be treated from one run to the other due to gravity.

For example, embodiments of the invention will only be explained in more detail with reference to the accompanying drawings, in which
Figure 1 is a partially sectioned view of the chamber;

709813/0749

FIG. 2 is a detailed view and shows the device for driving and rotating the elements in the chamber; Figure 3 is a longitudinal section on a larger scale the advancing device of the chamber of FIG. 1 and FIGS. 4 and 5 are partial longitudinal sections through two embodiments the drive device of the elements to be treated.

The invention is described as applied to fibrous insulating shell bodies A, which consist of a felt in which a binding agent is distributed, in particular of the kind described in the above patent application. This device is for the whole and uniform curing of the shell bodies determined, wherein polymerization or curing of the binder are ensured.

During curing in the chamber or in the heating oven or continuous furnace, the shell bodies are moved without the use of force, in such a way that delamination of the Outer layers and the formation of surface defects that are harmful to the appearance are avoided. On the other hand, the shell bodies are kept completely flat over their length during the dwell time in the heating furnace and make complete rotations about their axis in such a way that the hardening is evened out.

The shell bodies A are guided one after the other in front of a gate 1 operated by a winch 2, whereby each Shell body is stopped before its entry. The opening of this gate is timed and limited, to reduce heat loss in the furnace.

In order to reduce the dwell time of the shell bodies in the heating furnace

709813/0749

longer while still "limiting its length" the continuous furnace has several levels on top of each other, five in the example shown.

Each of these levels consists of a perforated floor made up of one or more parts on which, the shell bodies A roll by being driven with the help of 4 rods which are driven with a continuous translational movement. Chains such as 5 firmly connected to the bars. The arrangement according to the invention is such that one of these endless chains 5 with their upper run for displacement in one direction, then in the other direction by means of their lower run on two consecutive ones Levels of perforated floors 3 ensures.

According to the example under consideration, three chains 5 with bars 4 are provided in order to obtain five levels lying one above the other. The chains are driven via a continuously variable transmission with drive via a chain which is in engagement with the sprockets 6.

The shell bodies A are placed on the perforated floors 3 deposited between two consecutive rods 4. The movement of the endless chain 5 provides the feed of the rods 4. Each of the shell bodies A is pushed through the rod immediately in front of it and becomes demonstrated by rolling on the support plate 3. Between the end 9 of the perforated floor under consideration and the last bar in front of the chain wheel 6 is a free one Space 7 is provided in such a way that a shell body A passes to the lower level due to gravity.

At this level, the rods 4 circulate in a de-

7098 1 3/074 9

opposite direction and are then driven by the return strand of the endless chain. It follows from this that the shell bodies under the same conditions on a horizontal transfer level in one direction opposite to that which they experience at the level immediately above. the Shell bodies finally leave the lower level 8 by rolling on an inclined plane 10.

The continuous furnace is heated by means of gas burners 12 which are arranged on the floor 13 of the continuous furnace and above which small arch stones 14 made of stainless metal are arranged to prevent localized overheating of the lower levels of the continuous oven or heating cabinet avoid. The homogeneous distribution of the rising warm air over the entire height of the continuous furnace is obtained by using a thin perforated sheet 15 that is parallel to the top of the arch stones 14 and below a certain distance to the latter is arranged.

After passing through contact with all of these shell bodies, the air is withdrawn via the chimney 16.

D _a s described and illustrated example relates to the jail that the elements to be treated A bearing floor 3 arranged horizontally.

According to the embodiments according to Figures 4 and 5 are these floors or plates inclined to the horizon.

The inclination of the floor 3 is corresponding to FIG. 4 - in the direction of movement of elements A seen - increasing; the rods 4, which touch these elements, then provide for their Drive.

Such an embodiment enables a regular
Rotation of the elements, even if the rotational shape
of these elements is imperfect.

Awake, the embodiment of Figure 5, the slope of the floor 3 is seen in the direction of movement of the elements A,
directed downwards. These are carried along by gravity and in this case the rods 4 ensure that their movement is regulated. In addition to the advantage mentioned above with reference to FIG. 4, this is beneficial. Arrangement of the bottom 3 the discharge of the material particles which may have detached from the elements A during their passage in the treatment chamber.
