Definitions

• the present invention relates to a device for separating substances of different flowability.
• the present invention further relates to a method for setting up a device for separating substances of different flowability and a method for operating such a device.
• Such devices and methods are used in various industrial areas. In principle, materials that have a different flow behavior can be separated. Such devices and methods are used, for example, in the recycling of animal bodies to separate skin, meat and / or tendon parts from bones or bones. These are also used to separate the flesh from the skin, stems, seeds or stones of vegetables or fruit. Another field of application is the separation of, in particular, composite packaging, for example cardboard beverage packaging, which consist of cardboard boxes coated with plastic film and / or aluminum film.
• the also referred to as separators devices for separating substances with different flowability usually include a hollow drum provided with a perforated jacket surface and a press belt that is operatively connected to the hollow drum in a partial circumferential area. Press belt and hollow drum are both driven. The material to be separated arrives in a feed area between the elastic press belt and the perforated hollow drum. The press belt, together with the hollow drum, forms a feed wedge for the material to be pressed in this feed area.
• a disadvantage of the known devices and methods is that when the material to be pressed is pulled in and when the materials of different flowability are separated, high pressure forces can act, which often have an unfavorable effect on the press belt. For example, there may be undesirable overstretching of the press belt.
• support elements of different designs arranged on the side of the press belt facing away from the material to be separated are used to support the press belt. The use of support chains has proven itself in so-called soft separators.
• the advantage of the support chain is a more even loading of the press belt that is guided over it.
• the support chain presses the press belt in a partial area of the looping of the hollow drum against the outer surface of the hollow drum. This causes the press belt to be guided, in particular in the area in front of the pressure roller, and thus reduces the occurrence of functional impairment and / or damage to the press belt.
• the support chains are pre-tensioned accordingly. Adequate guiding and support of the press belt is guaranteed, however, a large pretension of the support chain leads to strong signs of wear of all components of the support chain and to a heavy load on the support chain bearings.
• Support chains of this type are generally supported by means of rollers, one roller being designed as a drive roller, while the other roller is a tensioning roller.
• the pretensioning of the support chain can be adjusted with the help of the position-variable tension roller, so that the pressure force that the support chain exerts on the press belt can also be adjusted.
• Devices of this type are known for example from documents DE 20 2004 014 365 U1 and DE 20 2007 004 473 U1.
• the hollow drums are also subject to wear. Their outer surfaces must be ground at regular intervals, reducing their diameter. A change in the hollow drum diameter can have a negative impact on wear and yield during the cutting process. In order to counteract these negative effects, in addition to the tension roller, the position of the drive roller relative to the hollow drum must also be adjusted. The adjustment is made regularly by loosening and re-adjusting a shaft clamp connection.
