Definitions

• the invention relates to a heat treatment machine for loading a material web which is continuously guided in the longitudinal direction with hot air from a hot air circuit, into which preheated fresh air which is to be blown off via an exhaust air flap and which is heated by means of heat exchangers is to be fed in via a supply air flap with the aid of heat exchangers.
• the invention relates to a fixing machine or a tensioning machine for loading a broadly guided textile web, wherein preheated fresh air is continuously fed into the hot air circuit by heated exhaust air.
• air means any gas to be used to operate a heat treatment machine.
• "Supply air and exhaust air flaps" are preferably mechanical closure flaps, but in principle the terms should encompass all types of valves.
• the still hot or heated exhaust air is used for preheating fresh air to be supplied from the respective hot air circuit.
• large-area hot air ducts or ducts are generally required, since the hot, gaseous medium is usually directed uniformly onto the web. Efforts are therefore made to seal the entire hot air duct as well as possible.
• this requirement for reducing heat losses is countered by the fact that the individual parts of the hot air circuit should also be able to be cleaned in the simplest possible manner and opened accordingly.
• the heat exchanger and its connecting lines to the associated machine can be integrated into the machine housing in such a way that the line losses are minimized and, moreover, a picture of the housing that is as closed as possible is created.
• the invention is based on the object of improving the above-mentioned hot-air treatment machine in such a way that, in particular, in the case of integrated .
• Arrangement of the device for heat recovery an automatic proportional control of the cross section of the supply and exhaust air line is to be provided with as little effort as possible.
• the solution according to the invention consists in the exhaust air flap and the supply air flap being mechanically coupled to one another in the sense of setting a fixed ratio of supply and exhaust air volume. This means, in particular, to spatially assign the flaps to one another in such a way that they can be mechanically connected to one another, preferably via a single rod.
• the invention therefore also consists in arranging the supply air and exhaust air ducts and the associated flaps in such a way that their opening and closing movements can be coupled mechanically, in particular via an adjusting rod.
• the supply air / exhaust air coupling according to the invention is also possible with an externally arranged heat recovery system.
• the drawing shows a cross section perpendicular to the direction of travel of a continuous web 3, in particular a textile web, which is continuously guided between chains 1 in a tensioning frame housing designated overall by 2.
• the treatment air is guided in the tenter frame in the direction of the arrow 4 shown by a fan 5 to nozzle boxes 6 and 7, from which the treatment gas is blown onto the material web 3.
• the gas then moves in the opposite direction away from the material web 3 via gaps provided between the nozzle boxes 6 and 7 extending transversely to the transport direction of the material web 3 into the spaces 8 and 9 above and below the nozzle box arrangement. From here, the treatment gas is returned to the suction chamber 11 of the fan 5 via a heating register 10.
• the exhaust air valve 13 is a flap.
• the exhaust air duct 12 contains a heat exchanger 14 in which cold fresh air supplied through a fresh air duct 16 in the direction of the arrow 15 is to be preheated.
• a glass tube heat exchanger 14 can be provided in the fresh air duct 16 .
• the supply air and exhaust air flaps 17 and 13 are far apart, for example. B. at such points on the machine or the channels that the simplest possible assembly of drive elements seems possible.
• the flaps 17, 13 are arranged according to the invention so that their opening movements are to be mechanically coupled.
• a connecting rod 18 is provided between the flaps as a mechanical coupling. It can be seen by selecting the connecting rod 18 or by adjusting the length of the connecting rod 18 that when one of the flaps 17, 13 is actuated, the other is moved accordingly. This enables a very simple mechanical control of the ratio of the quantities of supply air and exhaust air - even with an integrated heat recovery device.
