Problems solved by technology

This undoubtedly leads to a limited production rate (in the case of a 60 mm thick mat of pressed material, the current limit is about 8 t / h), because when the permeable belt has the maximum tensile strength, this leads to the length of the hardened section limit, the length limit depends on the product density

Embodiment Construction

[0031] figure 1 A schematic side view of a device for producing insulating panels according to the invention is shown. Between the upper circumferential screen belt 5a and the lower circumferential screen belt 5d, a pressed material at least partially made of lignocellulosic particles wetted with a binder is placed in the first zone Z1 and the second zone Z1. are processed in zone Z2. The separation of the zones is shown schematically in all figures by vertical dashed lines.

[0032] In the past, the pressed material mat was heated with steam or a steam-air mixture in the upper and lower sieve surrounds and finally hardened by heat application via die plates. Only speeds up to the tensile strength limit of the screen can be achieved.

[0033] now at figure 1 It can be seen that two further surrounding sieve belts are arranged within the surrounding upper sieve 5a and the surrounding lower sieve belt 5d. In the upper part of the device, these screen belts have the referenc...

Abstract

The invention relates to a device and a method having a first and a second zone (Z1, Z2) for producing insulating or acoustic panels from a pressed material mat (2) which consists at least partially of lignocellulose particles coated with binders, the first zone (Z1) being designed for heating and / or compressing the pressed material mat, and the second zone (Z2) being designed for curing the pressed material mat with the aid of calibration plates (3), and there being driven circulating screen bands (5a-5f) in contact with the upper and lower pressed material mat surfaces. According to the invention, to increase the production speed, at least four circulating screen bands (5a-5f) are used, at least two of which are in operative contact with the pressed material mat (2) in the region of the first zone (Z1), and at least two of which are in operative contact with the pressed material mat (2) in the region of the second zone (Z2).

Description

technical field [0001] The invention relates to an apparatus for producing insulating or acoustic panels from a mat of pressed material at least partially made of lignocellulosic, wetted with an adhesive, having a first zone and a second zone. wherein the first zone is configured for heating and / or compressing a mat of pressed material, and the second zone is configured for hardening the mat of pressed material by means of a sizing plate and driven around A screen belt is disposed in contact with the upper and lower pressing material mat surfaces. [0002] Furthermore, the invention relates to a method for producing an insulating or acoustic panel from a mat of pressed material at least partially composed of lignocellulosic granules moistened with a binder, using the mentioned apparatus production. Background technique [0003] Such a device is known, for example, from DE 10 2008 039 720 B4. In some cases, such plants have serial pre-compression devices or post-acting com...
