Definitions
- the invention relates to a dryer having an upper row and a lower row of rolls, wherein the rolls are arranged interchangeably in the dryer.
- contact dryers for drying web or filamentary material
- an upper and a lower row of rollers are arranged such that the material to be dried rotates each roller with a wrap angle of approximately 180 °.
- the known contact dryers have the advantage of good accessibility to insert the web or thread-like material or to intervene in case of possible disturbances can.
- the contact dryers must be completely enclosed. Since the roll surfaces are subject to mechanical and / or chemical wear during operation due to the product, the rolls must be replaced after a certain operating time to rework the surfaces.
- the well-known closed housing causes a considerable effort in the removal of the rollers, since the panel must be partially completely disassembled. The disassembly of the panel can cause a higher cost than replacing the rollers. This is associated with long downtime of the entire system.
- the invention solves the problem by the teaching of claim 1; Further advantageous features of the invention are characterized by the subclaims.
- the dryer comprises an upper row and a lower row of rolls, the rolls being arranged interchangeably in the dryer.
- each roller module comprises a roller with two bearings and with a front and rear support.
- the fact that the rollers are arranged with the storage on the supports, can be removed by disassembly of the supports in a few steps, the roller module from the dryer and replaced.
- the downtimes are reduced considerably, so that the plant availability can be significantly increased.
- the concept of the removable and replaceable roller module the heat loss of the dryer can be significantly reduced, especially if only one roller has a defect and must be replaced quickly.
- a lower roller module is releasably secured with its support on the frame of the dryer.
- the upper roller module is releasably secured with its support on a frame.
- the frame thereby generates the distance of the upper row of rolls to the lower row of rolls and corresponds approximately to a roll diameter, so that the endless sheet-like material wraps all rolls by approximately 180 °.
- the attachment of the lower roller module to the frame and the attachment of the upper roller module to the frame allows a simple construction of the dryer.
- On the frame of the dryer so alternately a frame for an upper roll module and a support for a lower roll module are arranged side by side.
- each roller has at least one frontally arranged opening into which a lifting device of an industrial truck can engage.
- the upper cladding of the housing or insulation of the dryer does not need to be dismantled during the lateral intervention of an industrial vehicle.
- the roller modules can be disassembled in a horizontal or horizontal position and pulled out laterally. This facilitates positioning during assembly or disassembly. At the same time, only a small opening in the casing of the dryer is necessary to disassemble the roll modules.
- At least one opening is rectangular and suitable to receive one or two forks of a forklift.
- the upper panel to be opened can be moved vertically along one or more guides. This makes it easy to open the panel so that the roller modules can be disassembled and replaced.
- the vertical mobility of the upper panel reduces the space required for the dryer, since according to the prior art, the walls or parts of the side panel had to be stored.
- the upper panel to be opened comprises a continuous panel as well as a structured panel arranged thereunder.
- the structured cladding can have viewing windows, recesses, etc. and is adapted to the design conditions of the dryer.
- the continuous panel is as simple and high quality executed in the insulation effect, so that the panel to be opened can be carried out inexpensively.
- the structured cladding has recesses corresponding to the bearings and supports of the roller modules.
- the heat loss of the dryer is minimized and at the same time the plant availability is increased.
- Figure 1 a side view of a closed contact dryer
- FIG. 1a is an illustration of an upper roller module
- FIG. 1 b an illustration of a lower roller module
- Figure 2 a perspective view of a partially opened
- Figure 1 shows a contact dryer 1 in which the rolls W1, W3, W5 and W7 form an upper row of rolls and the rolls W2, W4, W6 and W8 a lower row of rolls.
- a web-shaped material 2 or alternatively endless threads or filaments are guided through an inlet opening 3 to the first roll W1, guided around it to a second roll W2 until all rolls are looped and the web-shaped material 2 is fed via an outlet opening 4 for further processing ,
- the rollers W1 - W8 are arranged so that the web-shaped material 2 wraps around them by approximately 180 ° and is thereby dried by the contact with the heated rollers.
- the upper row of rolls W1, W3, W5, W7 is arranged vertically offset from the lower row of rolls W2, W4, W6, W8 by approximately one roll diameter.
- All rollers are mounted on both sides in each case a bearing 5, wherein the bearings 5 are arranged on a support 6 in the upper row of rollers W1, W3, W5, W7, which in turn are mounted on a frame 7.
- the frame 7 essentially produces the vertical distance to the lower row of rollers.
- the lower row of rollers W2, W4, W6, W8 is arranged with their bearings on both sides 5 on a respective support 8, which in turn is attached to the frame 9 or foundation of the contact dryer 1.
- rollers W1, W3, W5, W7 take place by releasing the supports 6 on both sides from the frame 7.
- a forklift can dive with its prongs or forks into at least one frontal opening 10 of the rollers W1 - W8 and pull out the entire roller including bearing 5 and support 6 from the contact drier 1.
- a new roller is used in reverse order.
- an upper roll module is formed by an upper roll, front and rear supports 6 and by two bearings 5, each of which is placed on a support 6 and supports the upper roll.
- the lower roller module is formed by a lower roller, a front and rear support 8, and by two bearings 5, each of which is arranged on a support 8 and supports the roller. Thanks to the modular design, each roller can be changed quickly and replaced with a new roller in just a few simple steps.
- a frame 7 for an upper roller module and a support 8 for a lower roller module are arranged side by side.
- a frame 7 for an upper roller module and a support 8 for a lower roller module are arranged side by side.
- a lateral frame or a lateral frame which accommodates the bearings for the rollers. Since the frame 7 for the upper roller module without spacing next to a support 8 for the lower Roll module is arranged and mounted on the frame 9, results in a self-stabilizing construction, which allows to disassemble individual roller modules or exchange.
- the at least one frontal opening 10 in the rollers allows easy handling and transport through any industrial truck. Since in large operations for transporting heavy loads forklift standard, the rectangular design of one or more openings 10, one or two forks of a forklift dive into the roller, lift them and drive the entire roller module out of the contact dryer 1 out. The rectangular opening on the forks of a forklift prevents twisting of the roller module during lifting and transport. This makes the roll change safer, but also more accurate, because the roll modules can be positioned accurately. If you wanted to replace the rollers by means of hall crane as in the prior art, a complete disassembly of the top and ceiling panels of the contact dryer would be necessary.
- the invention thus enables a roll change, in which only a part of the side panel of the contact dryer must be opened.
- the enclosure of the contact dryer 1 has been adapted to a quick roll change.
- the entire panel of the contact dryer 1 is shown closed.
- Behind the closed cladding rollers W1 - W4 are indicated.
- the cladding or housing of the contact drier 1 comprises a solid, non-openable cladding, of which a cladding 12 can be seen in the region above the end faces of the rollers.
- the side walls with the inlet and outlet ports 3, 4 are also designed so that they can be disassembled with effort, but not open by default.
- the ceiling cover of the contact dryer is firmly mounted and not open by default.
- An upper cladding comprises a continuous cladding 13, as well as a structured cladding 14 arranged thereunder, which is adapted to the supports 6, 8 and the bearings 5.
- the upper panel 13, 14 is vertically movable along one or more guides 11.
- the upper panel 13, 14 of the contact dryer 1 is opened so far that the rollers W5-W8 can be exchanged.
- the continuous panel 13 with the textured panel 14 have been pushed vertically along the guide 11. Since the cladding elements 12, 13, 14 are thermally insulated and therefore correspondingly heavy, a mechanical or automatic drive 17 can raise and secure the movable cladding 13, 14.
- the rollers W5 - W8 can be pulled out of the contact dryer 1 after loosening fasteners with the supports 6, 8 and the bearings 5, in which, for example, a forklift with its fork enters the at least one opening 10 and the roller out of the contact dryer 1 out moves. After changing the rollers, the upper panel 13, 14 is drained again.
- the structured cladding 14 has recesses 15 which correspond to the shape of the bearings 5. Furthermore, the structured cladding 14 has recesses 16 which correspond to the supports 6 and the bearings 5 arranged thereon. Thus, the upper panel 13, 14 rests on the supports 6, 8, so that they are not covered. This results in the possibility to start with the dismantling of the rollers already with the enclosure closed or to prepare it, so that a possible heat loss of the contact dryer 1 can be minimized.
