Description

Apparatus and process for producing layers from rock fibers and similar insulating fibrous materials
The invention relates to an apparatus and to a process for producing layers from rock fibers and similar insulating fibrous materials. The apparatus and the process of the invention are used in the manufacture of insulating plates and felt layers from rock fibers and similar insulating materials .
Several technological processes for producing layers of insulating plates and felts have been known . in the art.
Initially, the basis of the manufacturing processes was the formation of the whole layer in the so-called collection chamber. Th'is process, however, presented many disadvantages, such as: a) uneven density transversally to the line, b) uneven density along the thickness of the layer, c) uneven density in the longitudinal direction of the line .
From here, the prior art moved towards the so-called inclined and drum collection chambers, followed by a cross laying device. With this layer-forming process many of the aforesaid disadvantages were avoided. However, problems still remain concerning the microdensities and the hardness properties of the products.
The object of the invention is to provide an apparatus and process for producing layers from rock fibers and similar insulating materials that will supply products of uniform density, microdensity and hardness.
According to the invention, the object is achieved with an apparatus and a process for producing layers from rock fibers and similar insulating materials according to the independent patent claims . In the research and development of new products with improved mechanical and physical properties we have developed a new technological manufacturing process, by means of which the fiber layer is intertwined several times - transversally at least twice - to form the final layer.
This manufacturing process yields a layer with uniform microdensities and a product with considerably improved physical and mechanical properties.
The present invention is described hereinafter with reference to an embodiment and two schematic drawings, wherein:
Fig. 1 is a projection view of an embodiment of the inventive apparatus, and
Fig. 2 is a side view of the drive of the collection chamber conveyor.
The rock or other . similar fibers which are formed and blown off the rotor are deposited in the form of a layer onto the steel conveyor 1 of the collection chamber. The conveyor 1 must operate at a very high speed. From there, the layer passes to the receiving conveyor 2 which carries the fibers to a pair of vertical oscillating belts 3. The pair of vertical oscillating belts 3 oscillate transversally to the advancement direction of the layer. Thus, the layer is deposited on the feeding conveyor 4 which conveys it further to another pair of vertical oscillating belts 5. The oscillating belts * 5 deposit the layer onto the deposit conveyor 6. Thereupon, the layer, obtained by the deposition of the preceding layers, is formed in the hardening chamber. The velocities of the respective belts and of the collection chamber may be adjusted in order to obtain a layer which is best suited for a specific target product.
Figure 1 represents an embodiment of the invention, showing the manufacturing process and the apparatus for depositing two transversal layers. In the industrial production, apparatuses with two, three, or four transversal depositing devices, arranged in a cascade, are used. The apparatus as such enables any given stage of transversal deposition to be selectively enabled, depending on the technological requirements of the specific target product.
According to the invention, the layer of fibers entering the hardening chamber consists of two, three, or more transversally deposited layers, which are preferably laid at an angle of 90° relative to each other. In the first depositing • stage the width of the layer is several times greater than or equal to the depositing span of the layer itself. By adjusting the depositing span of the individual stages, the orientation of the fibers in the final layer may be regulated, regardless of the depositing span of the final stage. By appropriately selecting the depositing span of the respective stages, the direction of the fibers may be adjusted to suit a predetermined product.
The apparatus of the invention is constructed in such a manner as to permit all, or several, or only one of the stages of transversal deposition to be employed at a time. The oscillating belts allow for sufficiently high depositing speeds at the various stages.
The collection chamber conveyor 1 is designed and constructed specifically for the required high speeds (up to 400 m/min) . The conveyor is shown in Fig. 2. A Gall chain with specially shaped lamellae 11 and with a step smaller than 100 mm is supported by supporting wheels 21 which are coated with an elastic, wear-resisting material. As a segment of the steel conveyor, the lamella 31 is fixed to the chain. Only one part thereof is shown in Fig. 2; the actual assembly obviously comprises two Gall chains, one on each side, the straight lamellae 11 being fixed on said Gall chains. According to the invention, therefore, the apparatus for producing layers from rock fibers and similar insulating materials consists of a conveyor 1 of the collection chamber, a receiving conveyor 2, at least two pairs of vertical oscillating belts 3, 5, at least one feeding conveyor 4, and at least one deposit conveyor 6. The two pairs of vertical oscillating belts 3, 5 oscillate with a controlled preset amplitude. The receiving conveyor 2 and the deposit conveyors 6 are positioned perpendicularly to the feeding conveyors 4.
The process for producing layers from rock fibers and similar insulating materials is performed as follows: the fibers are transported by the conveyor 1 to the receiving conveyor 2, which then carries them into the nip formed by the first pair of vertical oscillating belts 3, which, in turn, deposit the fibers in a zigzag onto the first feeding conveyor 4, from where they pass between the second pair of vertical oscillating belts 5, which deposit them in a zigzag onto the first deposit conveyor 6, wherein the zigzag deposition may be repeated so that the layer of fibers entering the hardening chamber consists of two or more transversally deposited layers, laid at an angle of 90° relative to each other.
