Problems solved by technology

Here, the problem arises that the binder and the particles glued with the binder can deposit on the inner wall of the descender, and thus the descender tends to become dirty
The mechanical construction necessary for this can be costly and it can be difficult to achieve a sustained high-efficiency seal

Embodiment Construction

[0086] Due to the large number of embodiments, the reference numerals 21x, 23x, 24x, 31x, 32x, 33x, 34x are subsequently introduced as references to multiple components, a to d being used instead to denote x.

[0087] exist figure 1 A schematic diagram of an overall view of the device for gluing granules with the metering device 2 at the beginning and the mixing device 7 at the end is shown schematically in . A descending channel 3 and a descending channel structure 10 which will be further described below are arranged between the dosing device and the mixing device. Here, the granules are fed as a granulate stream 1 from the granulate silo into the dosing device 2 , usually by means of a discharge device, are weighed there, and enter the descending feeder via a conventional belt regulator (not shown) for dosing. Road 4. In the downcomer, the particle flow or particles 1 are dispersed and / or distributed onto the dispersion device 3 and there dispersed and / or distributed into...

Abstract

The invention relates to a downcomer structure (20), in particular a device for gluing granules (1) at least partly composed of fibers and / or chips suitable for producing material sheets , wherein the descending channel structure (20) has a descending channel (21), the descending channel has an inlet for feeding particles (1) and an outlet for outputting particles (1), and has a (21) At least one first cleaning device of at least one inner wall (21). The object of the present invention is to provide a descending channel structure which can effectively prevent solid viscous material from forming in the descending channel. The invention is moreover intended for very different types of downcomers and can be modified for integration into existing installations. The crux of the invention is that the downcomer structure (20) also has at least one second cleaning device for cleaning the at least one first cleaning device. (1443).

Description

technical field [0001] The invention relates to a descending channel structure. Background technique [0002] The production of material panels from, for example, chips or medium-density fibers or other flowable materials is an automated process and has been used in many countries for many years. As is known, the pressing of the preprocessed chips or fibers is carried out either in a cyclic manner or continuously. In addition to the many plant components located before and after the press, the production of the spreading mat by means of the spreading machine plays a prominent role here, however, in addition to the quality of the raw material, the quality of the produced spreading mat is also an important factor. The desire to manufacture inexpensive panels of materials from natural raw materials and man-made binders has forced producers to develop more efficient manufacturing methods. Particular emphasis is placed here on particularly low downtimes and low wear. [0003] ...
