TH6000B - Processing and equipment for collecting mineral fibers - Google Patents

Abstract

The invention involves collecting the fibers under the fiber-making machines with the aim of obtaining the filaments. It offers self-contained collection zones to each fiber-making machine. The surface of the collection area increases in the direction of increasing density. The invention also proposes a device that is characterized by having 2 reels per 3 filament machines.

Claims (27)

1. The process supports the separation of fibers and gases produced by multiple fiber-making machines in order to obtain a fiber sheet in which the fibers are collected by vacuum extraction, where each fiber-making machine (i) has its own collection area (Zi). The collected fibers are removed from the collection area by one or more conveyor belts shared for multiple collection areas (Zi) which are characterized by the trajectory of such conveyor belts being convex and that the surface of the collection area (Zi) rises in the direction in which the material rises on such conveyor belts. 2. The supporting process under claim 1 is characterized by fibers being removed via two inward-facing conveyor belts and by the surface area of the collection region (Zi) increasing in the direction of the position where the composite fiber sheet was last formed. 3. The supporting procedure under claim 1 or 2 is defined as having a constant return flow rate. 4. The supporting procedure under claim 3 is characterized by a zero return flow rate. 5. The process supporting any one of the claims 1 through 4 is characterized as the collection area (Zi) being part of a conveyor belt. 6. Any one of the supporting procedures under claims 1 through 5 shall be characterized by the same low pressure applied to the fiber sheet for all collection areas (Zi). 7. Any of the supporting processes under claims 1 through 6 are characterized by varying fiber drop heights depending on their fiber-making machinery. 8. Any of the supporting processes under claims 1 through 7 are characterized in which the increase in the surface area of the collection area (Zi) is achieved by modifying the angle of inclination of the relative perpendicular to the collection area relative to the rotation of the fiber-making machine used in conjunction with the collection surface. 9. The process supporting claim number 8 is characterized by the surface area of the collection area (Zi) being increased by increasing the distance (E) between the axes of the fiber-making machine. 10. The supporting process under claims 8 and 9, which is characterized by an increase in the area of the collection area as a result of the increased tilt of the axis of rotation of the fiber-making machine. 11. Any of the supporting processes under claims 1 through 10 are characterized as a fiber extraction process being applied to the primary material to aid in its extraction from the collection area. 12. The supporting process under any of Claims 1 through 11 is characterized by the fiber-making machines being arranged in groups of 3 or 4 machines with 1 receiving module for each group. 13. The support procedure under claim 12 is defined as such that the receiving module is installed in series. 14. The support procedure under claim 12 is defined as such that the supporting modules are installed in parallel. 15. The supporting process under claim 13 or 14 is characterized by the primary material being formed by each supporting module being constructed by parallel layering. 16. The supporting process under claim 13 or 14 is characterized by the primary material formed by each supporting module being assembled by cross-layering. 17. The supporting process under claim 16 is characterized by the primary material being assembled by stacking at least six interlayers of the primary material. 18. Any of the supporting processes under claims 1 through 17 are characterized by a collection surface consisting of a wheel. 19. The supporting procedure under claim 18 is defined as follows: a pair of wheels are arranged per group of three fiber-making machines. 20. Any of the supporting processes under Claims 18 and 19 are characterized in such that the minimum drop height of the mineral fibers results in a fiber impact velocity on the wheel of less than 20 m/s. 21. The support procedure under claim 20 is defined as having a minimum fall height between 2500 and 5000 millimeters. 22. Support devices for insulating mineral fibers, specifically glass fibers, for the purpose of separating the fibers and surrounding gases beneath the fiber-making machine so that a fiber sheet can be obtained in conjunction with groups of three fiber-making machines, each group of which each fiber-making machine (i) has its own collection area (Zi). The collected fibers are removed from the collection area by one or more conveyor belts shared for multiple collection areas (Zi). The support device, constructed by a cover, contains a pair of wheels (21) perforated across its entire circumferential surface and is equipped with a centering and supporting device for the internal suction, which is characterized so that the surface area of the collection area (Zi) increases in the direction in which the material increases on such conveyor belts. 23. The equipment under claim 22 is characterized by the vacuum wheel and bottom being equipped with cleaning and drying devices. 24. One of the devices under claims 22 to 23 is characterized as being composed of an endless conveyor belt placed beneath the wheels, which from this point directly separates the primary material. 25. Any device under claims 22 through 24 is characterized as being further comprising an overlapping device. 26. The device under claim 22 is characterized in which each wheel is driven by a pair of rollers. 27. Any device under claims 22 through 26 is characterized by rollers exerting a small pulling force on the primary material before it is collected by an endless conveyor belt.
