Embodiment Construction

[0026] Figure 1 shows the schematic structure of a plant, which shows a partial view of a multilayer press 1 with three press plates 2, two plate layers 3 formed therethrough, one with steam storage The steam device of the tank 8, and the steam introduction pipe 12 drawn from the storage tank to the multi-layer press 1. The lead-in pipe is connected in the lower region of the multilayer press 1 to the first vertical through-hole of the press plate 2 and can be applied to the pressed product mat 4 via the supply channel 33 and the ducts present in the press plate 2 if required. steam. This is only shown schematically in the middle press platen 2 . On the press platen 2 of the upper deck 3 , vertical supply channels 33 are connected to the process gas discharge duct 13 and via the duct 13 to a vacuum device 16 or directly to a gas purifier 31 .

Abstract

The press (1) has guiding channels provided in press plates (2) for process gases, where the guiding channels are equipped with openings, and through holes are arranged in the press plates. Supply channels run perpendicular to press surfaces through the arrangement of supply channels (33) over tires (3). A connection unit is arranged between the press surfaces of the adjacent press plates, and connections to distribution channels are provided in the through holes of the press plates.

Description

technical field [0001] The invention relates to a single-layer or multi-layer press for the manufacture of material panels according to the subject matter of claim 1 . Background technique [0002] During the manufacture of sheets of material by means of single- or multi-layer presses, during the application of heat and pressure to the mat of pressed product to be deformed, usually consisting of glued and loosely separated chips or similar particles, Toxic waste gas will be formed, which needs to be removed by appropriate special methods such as industrial waste gas scrubbing or waste gas incineration. The term "material board" means in particular a compacted board, an OSB board made of an directional diffused press, or an MDF board made of medium-density fibers. In this case, the pressed product mat is conveyed directly or after preparation by means of a scattering machine on a screen or on a belt into a single-layer or multi-layer press and pressurized there. The harmful...
