Embodiment Construction

[0031] figure 1 A schematic diagram of the fiber preparation system in the first embodiment is shown, and the fiber preparation system has a series of fiber processing machines. The air extraction system with the filter house 7 is common throughout the fiber processing system, and the air extraction system usually has an exhaust fan and a filter. The clean exhaust air 54 is exhausted from the filter house 7 to the environment or otherwise used in the spinning mill. The filter house has at least one first suction port 8 and one second suction port 9. The exhaust air is sucked in at a constant pressure via both the suction ports 8 and 9. Starting from the filter house 7, the air extraction system includes an ID fan 12 and a collection line 10. The ID fan is connected to the second suction port 9 on the filter house 7 via a pressure line 11, and the collection line is connected to the first suction Port 8. The air extraction duct originating from a separate machine, the air ext...

Abstract

The invention relates to a fiber preparation system with of a succession of machines (1-6) and conveyor sections (14-18) that are arranged between the machines (1-6) for pneumatic flock conveyance andan air extraction system for extracting exhaust air from the conveyor sections (14-18). The air extraction system has an ID (induced draft) fan (12) that is connected by means of a suction line (13)to at least one of the conveyor sections (14-18) via air extraction ducts (34, 37, 45) emanating from the suction line (13) and associated with the respective conveyor section (14-18). The air extraction ducts (41, 48) that are not connected to the suction line (13) are brought together in a collecting line (10).

Description

Technical field [0001] The invention relates to pneumatic fiber bundle transmission, to an air extraction system in a fiber preparation system, and to a method for controlling volume flow and pressure distribution in a fiber preparation system. The fiber preparation system includes a series of machines, a conveyor section for pneumatic fiber bundle transmission arranged between the machines, and an air extraction system for extracting exhaust air from the conveyor section. Background technique [0002] Fiber processing machines such as bale openers, cleaners, separators, intermediate storage containers (so-called "condenser"), mixers or carding machines are used in fiber preparation and are used for cleaning, mixing fiber materials and removing fibers The material is dispersed into individual fibers and the fibers are parallelized. A fundamental distinction can be made between the two types of machines. Machines of the first type include, for example, condensers or intermediate...
