DE2849655A1 - Conveyor track in tunnel kiln for baking ceramic prods. - which rest on trays supported by balls rolling round oval grooves in hearth plates - Google Patents

Abstract

The bed of the track is formed by two rows of plates, where the plates in one row are staggered w.r.t. the plates in the other row. All the plate contain an oval track formed by a groove and contg. balls. The workpieces rest on trays which travel through the kiln on the balls, which roll round the oval tracks during the transport of the trays. The invention ensures that the balls are at a relatively constant temp. in their respective parts of the kiln, and is an improvement on the conveyor track described in DT22220392, in which the balls roll right through the kiln and are then carried back to the kiln inlet.

Description

Transport track in a tunnel kiln for firing ceramic goods.

Dic: The invention relates to a conveyor track in a tunnel fen for firing ceramic goods, with those listed in the preamble of the claim Features.

In DE-OS 22 20 392 such a transport path is described, in the case of the ctie, the balls carrying the sledges with the sledges through the combustion channel be guided. The balls are placed on the rolling plates at the entrance of the firing channel placed and at the exit of the firing channel from the roll-off plates and again transported back to the entrance of the firing channel for reuse.

This return transport of the balls involves considerable structural engineering Expenditure for the creation of corresponding machines wd transport devices in advance.

Auel} the balls are exposed to a strong temperature change, which has a detrimental effect on the service life.

The invention is based on the object of a transport path in vain To create a tunnel furnace for firing ceramic goods, in which the z ': m wear and further conveying the sled serving balls depending on the location in the firing channel are exposed to an approximately constant temperature These The object is according to the invention by the characterizing part of the claim listed features solved.

Since this is the placement and removal of the balls from the roll-off plates and there is no need to transport the balls back, this has an advantageous effect on investment costs the end.

Since the balls run around in the oval-shaped grooves and on remain at the intended location in the area of a roll-off plate the balls subjected to a constant temperature effect, so that the service life of the balls reaches a higher value.

The fact that only the balls that are during the concentricity in the Oval-shaped grooves are located on the edge of the transport track, the sledges to carry it further, while the other balls circulate unloaded, is the Wear on the balls kept low.

In the drawing, a transport path according to the invention is based on an embodiment shown schematically. 1 shows a partial plan view onto the transport path, the carriages being omitted, FIG. 2 a section according to line II - II in FIG. 1.

The conveyor track 1, which is in a tunnel kiln for firing ceramic Can be well arranged, consists of two rows 2 and 3 adjacent Roll-off plates 4. The roll-off plates 4 of row 2 are to the roll-off plates 4 of the Row 3 staggered. The roll-off plates 4 lie on the floor or

The bottom line of the firing channel is only up and down gutters depending on the load be replaced.

Each Abreilplatte 4 has a channel 5 on the top, in the form of a Ovals runs. The grooves 5 take balls 6, which in the grooves 5 in the round roll off.

The balls 6 located in the edge area 4a of the transport path 4 carry Carriages 7, which have a recess 8 corresponding to the rolling area of the balls 6, in such a way that the balls 6 located in the edge area 4a carry the slide 7, while the balls 6 located in the inner region 4b of the transport path 4 have no load capacity circulate freely.

Due to the movement of the slide 7, the balls 6 are continuously removed the edge area 4a into the inner area 4b and from there in turn into the edge area 4a kept in constant circulation.

Thus the circulation of the balls 6 from the inner area 4b into the edge area 4a is facilitated, the transport path 1 can move in the direction of movement of the carriage 7 rise slightly so that the balls 6 with a slight slope the inner area 4b run through.

The grooves in the edge area 4b can also be opposite to the direction of movement the carriage 7 rise slightly to the middle of the oval-shaped circuit and then fall off, so that here too the balls 6 by themselves from the inner region 4b into the Reach edge area 4a.
