Definitions

  • the invention relates to a dryer for drying continuously conveyed goods and a method for drying continuously conveyed goods with the features of the preamble of the independent claims.
  • dryers are used in a variety of different embodiments for drying threads or fabric webs that have been treated with water or other media.
  • heated air streams are used for drying, which evaporate the liquids, for example the water, and remove the water vapor.
  • Such dryers are also used for sizing threads. After the size has been applied to the threads, excess water must be removed from the threads in a drying process.
  • the productivity of such dryers depends on various parameters. The higher the temperature of the dryer is selected, the higher the drying effect and the faster the system can be operated. However, the temperature cannot be chosen to be arbitrarily high because excessive temperatures would destroy the threads, which often consist of plastic or contain plastic.
  • a high dryer performance can also be achieved by simultaneously feeding several threads through the dryer in a group of threads. It is also possible to pass several layers of threads through the dryer. But as soon as too many layers of threads on top of each other there is a risk that threads lying inside the thread sheet will no longer be dried sufficiently.
  • the introduction of threads into the dryer by the operating personnel should also be simplified. According to the invention, this object is achieved with a dryer for drying continuously conveyed goods and with a method for stopping or temporarily interrupting drying with the features of the characterizing part of the independent claims.
  • the dryer for drying continuously conveyed goods is used in particular for drying a sized sheet of thread.
  • the dryer has a first dryer arrangement and a second dryer arrangement, between which a passage for the passage of the goods to be dried is formed.
  • the first The dryer arrangement and the second dryer arrangement are designed to be movable with respect to one another such that the passage for carrying the goods through in a stop position of the dryer is larger, ie has a larger cross section than in an operating position.
  • the provision of two dryer arrangements allows effective drying of larger thread sheets, since heat acts on the thread sheet from two sides.
  • the first and the second dryer arrangement are arranged one above the other and the second dryer arrangement located at the top is designed to be raised. In the event of a plant shutdown, the second dryer arrangement is moved into the
  • the dryer arrangements remain essentially parallel to each other.
  • the cross section of the passage corresponds approximately to the cross section of the thread sheet to be dried.
  • the passage has a larger cross-section in the raised stop position.
  • the hot air can escape laterally between the two dryer arrangements.
  • a new thread can be easily carried out by the operating personnel from the side of the dryer through the gap formed between the lower edge of the upper dryer and the upper edge of the lower dryer. in this context it is advantageous if the space around the dryer is free of installations, for example supports or the like, so that access to the gap is not made more difficult.
  • the dryer arrangements are designed as warm air dryers, in which a warm gas stream can preferably be guided approximately parallel along the goods.
  • the dryer can be provided with one or more gas burners for heating the air flow.
  • Each dryer arrangement advantageously has several, advantageously two, gas burners.
  • the gas burners can be individually regulated. This makes it possible to achieve a homogeneous temperature distribution of the air over the entire width of the dryer.
  • the heating of the air flow by means of steam or thermal oil heating coils is also conceivable.
  • the passage between the first and the second dryer arrangement is sealed at the side.
  • the side seal prevents heat loss in normal operating conditions.
  • a dryer for drying continuously conveyed goods in particular for drying a sized sheet of threads, which has a first and a second dryer arrangement.
  • the goods to be dried are carried out between the first and the second dryer arrangement.
  • the first dryer arrangement and the second dryer arrangement are designed as warm air dryers, in which a warm gas flow can be guided approximately parallel along the goods. Because drying takes place from two sides of the goods, it is possible to use thicker ones Thread coulters to dry without the risk that the heat will not get to threads lying further inside the coulter. The amount of threads dried at the same time can therefore be increased while the treatment speed remains the same.
  • the first and the second dryer arrangement are preferably formed symmetrically to one another with respect to a plane of symmetry.
  • the plane of symmetry lies approximately in the middle of the path for the goods to be dried.
  • the invention therefore provides for a second, identical dryer arrangement to be provided on the opposite side of the product in a dryer arrangement known per se with a warm air flow parallel to the product.
  • a dryer as described above is used in particular.
  • the movement of the goods is stopped, for example due to a thread break.
  • the first dryer arrangement is moved with respect to the second dryer arrangement in such a way that the passage for the goods formed between the first and the second dryer arrangement is enlarged.
  • the second dryer arrangement located above the first dryer arrangement is started up.
  • FIG. 1 shows a schematic representation of a system for sizing threads with a dryer according to the invention
  • FIG. 2 cross section through a dryer according to the invention in an operating position
  • FIG. 3 side view of the dryer arrangements from FIG. 2 in the operating position
  • FIG. 4 cross section through the dryer according to FIG. 2 in a stop position
  • FIG. 1 side view of the dryer assemblies in the stop position.
  • FIG. 1 schematically shows a device for sizing threads, for example weaving warps, which has a dryer 1 with the features of the invention.
  • the weaving warp W to be sized is supplied with size in a size application unit 10 and then passed through the dryer 1.
  • the dryer 1 consists essentially of two dryer arrangements 2, 3. Between the lower dryer arrangement 2 and the upper dryer arrangement 3, a passage 4 is formed for the goods w to be dried.
  • the dryer arrangements 2, 3 are designed as warm air dryers.
  • the goods W are acted upon from above and from below with a hot gas stream G which runs approximately parallel to the goods W.
  • a cross section through the dryer 1 is shown in FIG.
  • a passage 4 with an approximately rectangular cross section is formed between a lower dryer arrangement 2 and an upper dryer arrangement 3.
  • the passage 4 serves, for example, to receive a family of warp threads W to be dried.
  • the warp threads are arranged in a family with a matrix-shaped cross section.
  • the dryer arrangements 2, 3 have side walls 7 which laterally delimit the passage 4.
  • the gap 14, which is formed between the lower edge 8 of the side wall 7 of the upper dryer arrangement 3 and the upper edge 9 of the side wall 7 of the lower dryer arrangement 2, is sealed with a sealant 6. Glass fabrics, for example, can be used as the sealant 6.
  • the dryer arrangements are provided with gas burners 5.
  • Each dryer arrangement 2, 3 has a gas burner 5 on both sides. The air circulating in the dryer arrangements 2, 3 can thus be heated homogeneously.
  • the upper dryer arrangement 3 is suspended from a frame 11.
  • the frame 11 is supported on lateral supports 13 and can be raised by means of an actuating device (not shown) comprising an electric motor and threaded spindles.
  • an actuating device (not shown) comprising an electric motor and threaded spindles.
  • the upper dryer 3 In the operating position B (see FIG. 2), the upper dryer 3 is arranged such that the gap 14 between the side walls 7 of the lower dryer arrangement 2 and the upper dryer arrangement 3 is closed.
  • FIG. 3 shows the two dryer arrangements 2, 3 according to FIG. 2 in a side view.
  • Each dryer arrangement has fans12.
  • the fans 12 are arranged in the area of the outlet of the goods W to be dried.
  • the fan 12 generates a NEN circulating gas stream G.
  • the gas stream G is heated in the gas burners 5 and in the area of the entry of the goods W into the dryer 1 approximately parallel to the goods W in the passage 4.
  • the gas flow G is sucked in again by the fans 12 in the area of the outlet W of the goods from the dryer, which results in a circulation.
  • the gas stream G is generally a pure air stream containing water vapor. However, it would also be conceivable to supply treatment media to the gas stream for the treatment of the goods W.
  • the lower dryer arrangement 2 and the upper dryer arrangement 3 are essentially identical and are symmetrical with respect to a plane of symmetry E lying approximately in the middle of the path for the goods W.
  • FIG. 4 shows a cross section of the dryer 1 in the stop position S.
  • the passage 4 formed between the lower dryer arrangement 2 and the upper dryer arrangement 3 has a larger cross section in comparison to the operating position B.
  • the gap 14 formed between the upper edge 9 of the side wall 7 of the lower dryer arrangement 2 and the lower edge 8 of the side wall 7 of the upper dryer arrangement 3 is no longer closed. Heat H prevailing in the passage 4 can escape through the gap 14, as shown schematically by arrows.
  • the upper dryer arrangement 3 is raised by 80 cm.
  • the gap 14 is therefore 80 cm.
  • the upper dryer arrangement 3 is moved at a speed of 50 mm per second. announce that the stop position is reached after 16 seconds.
  • the speed is also variably adjustable.
  • FIG. 5 shows the dryer arrangements 2, 3 in side view and in stop position S. After a thread breakage, the goods W can be passed from the side through the gap 14 through the dryer.
  • the upper dryer arrangement 3 is preferably raised by a motor in the event of an interruption in operation.
  • the start-up can be triggered manually or automatically. Automatic triggering can take place, for example, as a result of a thread break (which can be detected automatically or manually) or also as a result of an excessive temperature.
  • the dryer arrangements 2, 3 are also advantageously switched off. This means primarily that the gas burner B and the fans 12 are put out of operation.
  • the dryer 1 enables the efficient drying of goods, for example a set of warp threads.
  • goods for example a set of warp threads.
  • up to 10 v 000 warp yarns are passed through the dryer.
  • a gas stream G with a temperature of up to 260 ° C. is passed over the goods W in the dryer.
  • the temperature of the gas stream G can be chosen so high because due to the open gap 14 in the stop position S, there is no heat build-up inside the dryer 1.
  • Efficient drying can be achieved in a similar manner if a first and a second dryer arrangement in the manner shown in FIG. 3 are used. It is not absolutely necessary to design the first and second dryer arrangements to be mutually movable if suitable precautions are taken to avoid a build-up of heat. For example, flaps that can be opened from the side can facilitate the outflow of the hot gas flow G in the event of an interruption in operation and enable lateral access to the goods W.
  • Corresponding flaps can be operated automatically or by hand.
