Description
"Water-cooled transport roller for a roller-hearth kiln"
Specification The invention relates to a water-cooled transport roller for a roller-hearth kiln comprising a cylindrical base body, a thermal insulation on the outer periphery of the base body, and a cooling water conduit placed in a central position in the base body, whereby the cooling water can be fed into the conduit at an end of the base body which is rotationally arranged, flows through the conduit, and then flows back through an annular chamber located between the conduit and the base body, after a change in direction on the exit side of the conduit.
According to an embodiment known from practice, from which the invention proceeds, the conduit is structured to narrow towards the water entry side, and held in place in the base body using a spacer. The water feed takes place by means of a water inlet pipe that is inserted into the narrowed connection end of the conduit. The water flowing back flows through between stays of the spacer and exits out of a face opening of a connection element inserted into the base body. A deflection head with radial bores is connected at the other end of the conduit, which head is clamped onto a mandrel. The water supply, particularly the water feed, proves to be a weak point of the known transport roller. Relative movements between the conduit held in the base body and rotating with the base body, and the water feed pipe that is arranged not to rotate, result in wear of the water feed pipe. The conduit built into the base body for supplying water consists of a thin-walled pipe with a great length, whose exact alignment in the rotation axis of the base body cannot always be guaranteed. In the case of an offset or a slight curvature of the conduit end, the water feed pipe inserted into the conduit is subject to significant shear stress, which results in damage to the water feed pipe after a short time. Even a short-term interruption of the water supply or even a disruption of the water supply immediately results in irreversible damage to the transport roller, due to the high kiln temperatures. The progression of damage, as described, occurs suddenly and is impossible to estimate during operation of the transport roller.
The invention is based on the task of further developing a water-cooled transport roller with the structure described initially, in such a way that a premature defect in the cooling water supply is precluded, to a great extent.
The task is accomplished, according to the invention, in that a shaft is fixed to the base body which exhibits a cavity for receiving the water input end of the conduit, a central bore aligned with the rotation axis of the base body, for feeding the cooling water, as well as drain channels for draining the water backflow, which run into a water collecting chamber, and that the shaft is rotationally connected to a water distributing head for feeding the central bore with cooling water and extracting the water backflow from the water collecting chamber. The teaching according to the invention proceeds from the damage analysis of the known embodiment as described above. In the arrangement according to the invention, the rotating passage required for the water feed and the water drain is shifted out of the region of the conduit into a module that consists of a shaft and a water distributing head. The elements of this module are solid, precision-machined components. In this connection, it can be guaranteed that the connection elements that rotate relative to one another align precisely, adhering to close tolerances. The end of the water-carrying conduit is fitted into the shaft so as not to rotate. Any offset relative to the rotation axis of the transport roller and/or any curvature of the conduit is therefore not harmful to the function of the arrangement according to the invention.
There are various possibilities for a further design development of the module consisting of shaft and water distributing head. One embodiment provides that the water distributing head has a water feed pipe that aligns with the rotation axis, and engages in a central bore of the shaft at its end, allowing rotational movement. According to another embodiment, the shaft has a cylinder journal that aligns with the central bore, which passes through a shaft passage of the water distributing head and can be connected with a device for cooling water feed, so as to rotate. In the case of both embodiments, it is practical if the water distributing head has a dead-end bore in the lengthwise direction for the water backflow, the diameter of which is greater than the outside diameter of the water feed pipe or the cylinder journal, respectively. The back-flowing water flows through an annular chamber delimited by the dead-end bore and the water feed, and exits through a cross-bore that opens into the dead-end bore.
According to an advantageous embodiment of the invention, the shaft can be screwed onto the face of the base body. For this purpose, it has a flange that can be attached to the face of the base body, and a connection end that is fitted into the base body, which centers the shaft on the base body.
In another embodiment, the invention teaches that a spacer with radial stays is arranged at the water exit end of the conduit, and that a hollow shaft is inserted into the base body, which shaft has a cavity for holding the spacer. In the embodiment as described, the water exits axially out of the conduit and its direction is changed in the cavity in which the spacer is inserted. This embodiment guarantees a large exit cross-section and thereby a change in direction of the water, which occurs with little pressure loss. This also contributes to reliable function of the cooling water supply. The hollow shaft can have a shaft extension for connecting a drive device.
According to a preferred embodiment of the invention, the thermal insulation on the periphery of the base body consists of a fiber mat made of inorganic fibers resistant to high temperatures, which is clamped in place between the base body and an outside pipe that forms the running surface, subject to elastic compression. The outside pipe is attached in known manner, on stays that are welded onto the base body. Suitable fibers are, for example, ceramic fibers, glass fibers, and Si02 fibers.
In the following, the invention will be described using a drawing that shows an exemplary embodiment. This schematically shows:
Fig. 1, a lengthwise cross-section through a water-cooled transport roller for a roller-hearth kiln structured according to the invention;
Fig. 2, the cooling water inlet end of the transport roller on a larger scale as compared with Fig. 1, also in lengthwise cross-section.
The transport roller shown in the figures consists, in its essential structure, of a cylindrical base body 1, a thermal insulation 2 on the outer periphery of the base body 1, and a conduit 3 for cooling water arranged in a central position in the base body 1. The cooling water can be fed into the conduit 3 at an end of the base body 1 which is rotationally arranged, flows through the conduit 3, and then flows back through an annular chamber 4 located between the conduit and the base body, after a change in direction on the exit side end of the conduit.
A shaft 5 is attached to the base body 1, which shaft exhibits a cavity for receiving the water input end 6 of the conduit, a central bore 7 aligned with the rotation axis of the base body 1 for feeding the cooling water, as well as drain channels 9 for draining the water backflow, which run into a water collecting chamber 8. The drain channels 9 consist of bores that are arranged concentrically around the central bore 7.
The water collecting chamber 8 consists of a cylindrical space that is closed off with a lid 10. The shaft 5 is rotationally connected to a water distributing head 11 for feeding the central bore 7 with cooling water and extracting the water backflow from the water collecting chamber 8. It is particularly evident from the enlarged representation of Fig. 2 that the water distributing head 11 has a water feed pipe 12 that aligns with the rotation axis, and engages in a central bore 7 of the shaft 5 at its end, allowing rotational movement. It is practical if a small gap is provided between the shaft end and the central bore 7, so that wear-free rotational movement of the water feed pipe 12 relative to the shaft 5 is guaranteed. Leakages and related slight reflux mixing between the inflowing water and the hot water backflow can be accepted without problems, if the water throughput performance is sufficiently high. However, a seal arrangement between the water feed pipe 12 and the central bore 7 is not supposed to be precluded. Mounting of the water distributing head 11, allowing rotational movement, takes place at the lid, which is structured as a bearing lid with appropriately machined bearing surfaces.
It is furthermore evident from Fig. 2 that the water distributing head 11 has a dead-end bore 13 in the lengthwise direction, for the water backflow, the diameter of which is greater than the outside diameter of the water feed pipe 12. A
cross-bore 14 for water discharge opens into the dead-end bore 13.
The shaft 5 has a flange that can be attached to the face of the base body 1 with screws 15, and a connection end that is fitted into the base body 1.
It is evident from the figures that a spacer 16 with radial stays 17 is arranged at the water exit end of the conduit 3. A
hollow shaft 18 is inserted into the base body 1, which has a cavity 19 for the spacer. The conduit 3 is arranged so as not to rotate, and centered by the spacer 16. The hollow shaft 18 can be welded onto the base body 1 or be flanged onto the face of the base body 1 with screws, analogous to the shaft 5 on the cooling water inlet end. The cooling water exits at the face of the conduit 3, and its direction is changed in the cavity 19 of the hollow shaft 18. It flows through the channels formed by the radial stays 17 of the spacer 16 and flows out in the annular chamber 4 between the conduit 3 and the base body l, whereby a heat exchange takes place with the hot base body 1, on the one hand, and with the cooled conduit 3, on the other hand. The hollow shaft 18 furthermore has a shaft extension for connecting a drive device.
The thermal insulation 2 consists of a fiber mat made of inorganic fibers that are resistant to high temperatures, for example ceramic fibers or Si02 fibers. The fiber mat is clamped in place between the base body 1 and an outside pipe 20 that forms the running surface and is made up of pipe segments, subject to elastic compression. The outside pipe 20, i.e. the pipe segments, are attached on stays 21 that are welded onto the base body 1 on the outside. The base body 1 is mounted on segments 22 on both sides of the heat insulation region.
Specification The invention relates to a water-cooled transport roller for a roller-hearth kiln comprising a cylindrical base body, a thermal insulation on the outer periphery of the base body, and a cooling water conduit placed in a central position in the base body, whereby the cooling water can be fed into the conduit at an end of the base body which is rotationally arranged, flows through the conduit, and then flows back through an annular chamber located between the conduit and the base body, after a change in direction on the exit side of the conduit.
According to an embodiment known from practice, from which the invention proceeds, the conduit is structured to narrow towards the water entry side, and held in place in the base body using a spacer. The water feed takes place by means of a water inlet pipe that is inserted into the narrowed connection end of the conduit. The water flowing back flows through between stays of the spacer and exits out of a face opening of a connection element inserted into the base body. A deflection head with radial bores is connected at the other end of the conduit, which head is clamped onto a mandrel. The water supply, particularly the water feed, proves to be a weak point of the known transport roller. Relative movements between the conduit held in the base body and rotating with the base body, and the water feed pipe that is arranged not to rotate, result in wear of the water feed pipe. The conduit built into the base body for supplying water consists of a thin-walled pipe with a great length, whose exact alignment in the rotation axis of the base body cannot always be guaranteed. In the case of an offset or a slight curvature of the conduit end, the water feed pipe inserted into the conduit is subject to significant shear stress, which results in damage to the water feed pipe after a short time. Even a short-term interruption of the water supply or even a disruption of the water supply immediately results in irreversible damage to the transport roller, due to the high kiln temperatures. The progression of damage, as described, occurs suddenly and is impossible to estimate during operation of the transport roller.
The invention is based on the task of further developing a water-cooled transport roller with the structure described initially, in such a way that a premature defect in the cooling water supply is precluded, to a great extent.
The task is accomplished, according to the invention, in that a shaft is fixed to the base body which exhibits a cavity for receiving the water input end of the conduit, a central bore aligned with the rotation axis of the base body, for feeding the cooling water, as well as drain channels for draining the water backflow, which run into a water collecting chamber, and that the shaft is rotationally connected to a water distributing head for feeding the central bore with cooling water and extracting the water backflow from the water collecting chamber.

In this connection, it can be guaranteed that the connection elements that rotate relative to one another align precisely, adhering to close tolerances. The end of the water-carrying conduit is fitted into the shaft so as not to rotate. Any offset relative to the rotation axis of the transport roller and/or any curvature of the conduit is therefore not harmful to the function of the arrangement according to the invention.
There are various possibilities for a further design development of the module consisting of shaft and water distributing head. One embodiment provides that the water distributing head has a water feed pipe that aligns with the rotation axis, and engages in a central bore of the shaft at its end, allowing rotational movement. According to another embodiment, the shaft has a cylinder journal that aligns with the central bore, which passes through a shaft passage of the water distributing head and can be connected with a device for cooling water feed, so as to rotate. In the case of both embodiments, it is practical if the water distributing head has a dead-end bore in the lengthwise direction for the water backflow, the diameter of which is greater than the outside diameter of the water feed pipe or the cylinder journal, respectively. The back-flowing water flows through an annular chamber delimited by the dead-end bore and the water feed, and exits through a cross-bore that opens into the dead-end bore.
According to an advantageous embodiment of the invention, the shaft can be screwed onto the face of the base body. For this purpose, it has a flange that can be attached to the face of the base body, and a connection end that is fitted into the base body, which centers the shaft on the base body.

This embodiment guarantees a large exit cross-section and thereby a change in direction of the water, which occurs with little pressure loss. This also contributes to reliable function of the cooling water supply. The hollow shaft can have a shaft extension for connecting a drive device.
According to a preferred embodiment of the invention, the thermal insulation on the periphery of the base body consists of a fiber mat made of inorganic fibers resistant to high temperatures, which is clamped in place between the base body and an outside pipe that forms the running surface, subject to elastic compression. The outside pipe is attached in known manner, on stays that are welded onto the base body. Suitable fibers are, for example, ceramic fibers, glass fibers, and Si02 fibers.
In the following, the invention will be described using a drawing that shows an exemplary embodiment. This schematically shows:
Fig. 1, a lengthwise cross-section through a water-cooled transport roller for a roller-hearth kiln structured according to the invention;
Fig. 2, the cooling water inlet end of the transport roller on a larger scale as compared with Fig. 1, also in lengthwise cross-section.
The transport roller shown in the figures consists, in its essential structure, of a cylindrical base body 1, a thermal insulation 2 on the outer periphery of the base body 1, and a conduit 3 for cooling water arranged in a central position in the base body 1. The cooling water can be fed into the conduit 3 at an end of the base body 1 which is rotationally arranged, flows through the conduit 3, and then flows back through an annular chamber 4 located between the conduit and the base body, after a change in direction on the exit side end of the conduit.
A shaft 5 is attached to the base body 1, which shaft exhibits a cavity for receiving the water input end 6 of the conduit, a central bore 7 aligned with the rotation axis of the base body 1 for feeding the cooling water, as well as drain channels 9 for draining the water backflow, which run into a water collecting chamber 8. The drain channels 9 consist of bores that are arranged concentrically around the central bore 7.
The water collecting chamber 8 consists of a cylindrical space that is closed off with a lid 10. The shaft 5 is rotationally connected to a water distributing head 11 for feeding the central bore 7 with cooling water and extracting the water backflow from the water collecting chamber 8. It is particularly evident from the enlarged representation of Fig. 2 that the water distributing head 11 has a water feed pipe 12 that aligns with the rotation axis, and engages in a central bore 7 of the shaft 5 at its end, allowing rotational movement. It is practical if a small gap is provided between the shaft end and the central bore 7, so that wear-free rotational movement of the water feed pipe 12 relative to the shaft 5 is guaranteed. Leakages and related slight reflux mixing between the inflowing water and the hot water backflow can be accepted without problems, if the water throughput performance is sufficiently high. However, a seal arrangement between the water feed pipe 12 and the central bore 7 is not supposed to be precluded. Mounting of the water distributing head 11, allowing rotational movement, takes place at the lid, which is structured as a bearing lid with appropriately machined bearing surfaces.
It is furthermore evident from Fig. 2 that the water distributing head 11 has a dead-end bore 13 in the lengthwise direction, for the water backflow, the diameter of which is greater than the outside diameter of the water feed pipe 12. A
cross-bore 14 for water discharge opens into the dead-end bore 13.
The shaft 5 has a flange that can be attached to the face of the base body 1 with screws 15, and a connection end that is fitted into the base body 1.
It is evident from the figures that a spacer 16 with radial stays 17 is arranged at the water exit end of the conduit 3. A
hollow shaft 18 is inserted into the base body 1, which has a cavity 19 for the spacer. The conduit 3 is arranged so as not to rotate, and centered by the spacer 16. The hollow shaft 18 can be welded onto the base body 1 or be flanged onto the face of the base body 1 with screws, analogous to the shaft 5 on the cooling water inlet end. The cooling water exits at the face of the conduit 3, and its direction is changed in the cavity 19 of the hollow shaft 18. It flows through the channels formed by the radial stays 17 of the spacer 16 and flows out in the annular chamber 4 between the conduit 3 and the base body l, whereby a heat exchange takes place with the hot base body 1, on the one hand, and with the cooled conduit 3, on the other hand. The hollow shaft 18 furthermore has a shaft extension for connecting a drive device.
The thermal insulation 2 consists of a fiber mat made of inorganic fibers that are resistant to high temperatures, for example ceramic fibers or Si02 fibers. The fiber mat is clamped in place between the base body 1 and an outside pipe 20 that forms the running surface and is made up of pipe segments, subject to elastic compression. The outside pipe 20, i.e. the pipe segments, are attached on stays 21 that are welded onto the base body 1 on the outside. The base body 1 is mounted on segments 22 on both sides of the heat insulation region.
