Definitions

  • the invention relates to a safety system for a roller mill according to the preamble of claim 1 known, for example from DE19 702 854 ,
  • roller mills have considerable advantages in terms of design and control as well as in terms of energy consumption, environmental behavior and overall economy.
  • roller mills are used both for the production of cement raw meal and for clinker milling and coal grinding. If raw material grinding plants are operated in conjunction with rotary kilns and a calcination plant, the kiln exhaust gases from the heat exchanger and clinker cooler process can be used for mill drying and for the pneumatic transport of the ground cement raw material or coal.
  • FIG. 1 Such a roller mill is shown in sections in a side view and without housing. Grinding rollers 2, each with a rocker arm 21 about a swing lever axis 22 in a Bearing 29 of a stand 20 are pivotally mounted, roll on a driven by a drive shaft 26 via a gear 4 grinding bowl 3.
  • the Wälzmühle according to Fig. 1 has two grinding rollers, of which only one grinding roller 2 is shown.
  • the stands 20, which are each associated with a grinding roller 2 are at its lower end in a region of a mill foundation 5, which is usually a concrete foundation, attached to a steel foundation frame 15.
  • the mill gear 4 is anchored via an intermediate plate or a gear base plate 27 in the mill foundation 5 or foundation frame 15.
  • An Indian DE 103 43 218 A1 described roller mill safety system provides for a constant availability of at least four grinding rollers by the arrangement of more than four grinding rollers, the grinding rollers are arranged in pairs opposite each other and four grinding rollers provide about 80% of the full mill power in a four-roller operation.
  • the roller mill is operated with four rollers after the defective grinding roller and its opposite grinding roller were swung out.
  • the advantage of this safety concept is that the roller mill continue to be operated with damage to the grinding rollers, rocker arm or suspension systems after a brief stop and swing a pair of grinding rollers with four grinding rollers can and the raw meal production and thus the furnace operation does not have to be stopped.
  • the swung-out grinding rollers, rocker arms or suspension systems can be separated or replaced.
  • roller mill must be put out of action in a gear damage, whereby the subsequent processes are interrupted and in a cement plant, for example, the clinker production is stopped. It is necessary to repair the gearbox and to pull it out from under the mill for this purpose, after removing the electric drive motor including the coupling and disconnecting all connecting piping to a lubrication system.
  • a replacement transmission can also be installed, if available. Repair and installation of a replacement gearbox, however, require several days of removal and installation time.
  • the invention has for its object to provide a security system for a rolling mill, particularly for a roller mill in modular construction, which ensures the transmission side with a low capital and installation costs, a high availability of the roller mill. According to the invention the object is achieved by the features of claim 1. Advantageous and advantageous embodiments are contained in the subclaims and in the description of the figures.
  • a basic idea of the invention can be seen to provide a change concept for the mill gear, which allows a rapid replacement of the mill gear and possibly the drive motor and the lubrication system and keeps the downtime and the resulting production loss extremely low.
  • a second gear is provided as a replacement or replacement gear
  • the mill gear and the exchange gear is arranged on at least one base plate.
  • the base plate is arranged, preferably in predetermined paths, adjustably on the mill foundation or the foundation frame and arranged on the base plate exchange gear can be damaged by adjusting the base plate in place of the mill gear, i. into the mill area and under the grinding bowl. According to the invention, this requires only an adjustment of the at least one base plate.
  • the mill gear located in operation and the electric drive motor connected to the mill gear via a torsionally flexible coupling are arranged on a horizontally adjustable base plate and aligned exactly with one another.
  • the units are arranged side by side and on a longitudinal axis of the base plate, and on the motor side facing away from the mill gear, a second mill gear as a Replacement or replacement gear and a connected via a clutch engine further pre-assembled.
  • the required lubrication system for the transmission lubrication is located between the mill gear and the replacement gear and connected via pipes to both gears.
  • the grinding bowl is lifted after loosening fastening screws and supported separately. Subsequently, the entire base plate is longitudinally displaced, such that the exchange gear is positioned under the grinding bowl. After lowering and fixing the grinding bowl, the mill operation can be resumed.
  • the particular advantage of this transmission safety concept according to the invention is that the defective transmission can be repaired without disturbing the grinding operation or removed for repair.
  • the safety system is suitable for cement plants and other central grinding plants and leads to significant time savings in a gearbox change.
  • Another advantage of this safety concept is that the loosening and subsequent reconnection of the lubrication lines, the time-consuming alignment of the individual components, gear, clutch, motor to each other, as well as the sequence of the removal and subsequent installation omitted or not respected.
  • the individual units are arranged side by side on the longitudinal axis of the base plate, and the base plate is designed to be displaceable in the direction of its longitudinal axis.
  • An alternative safety system provides a common base plate with a pre-assembled mill gear, a replacement gearbox and a common lubrication system, which can be adjusted horizontally.
  • the drive motor arranged outside the base plate is disassembled and mounted on the opposite side after the base plate has been moved to its new position.
  • the replacement gear is positioned in the mill center and under the grinding bowl and is connected to the displaced drive motor.
  • Another alternative provides a transmission-safety system in which the base plate with the aggregates arranged thereon not only horizontally and in the direction of the longitudinal axis of the base plate is displaceable, but can also be rotated about a vertical axis.
  • the operating mill gear, the lubrication system and the exchange gear are mounted, while the drive motor outside of the adjustable base plate on a separate frame or a console, which allows the alignment of the shaft journals of transmission and motor to each other, is arranged.
  • the base plate in the opposite direction, relative to the drive motor, linearly displaced from the mill area and outside the mill area by 180 ° about the vertical axis, which may be provided in the lubrication system rotated. Thereafter, the base plate is pushed back in the direction of mill area and drive motor, the exchange gear is now arranged under the grinding bowl in the operating position and can be connected to the drive motor via the clutch.
  • the base plate is dimensioned such that an arrangement and longitudinal displacement between each two stands of the roller mill is ensured.
  • Roller mills with an odd number of rolls e.g. Three- or five-roller mills are the preferred catchment area of the following gearbox variant.
  • a first and second base plate are used.
  • the mill gear, the drive motor and the clutch are mounted aligned with each other.
  • the replacement gearbox, the second motor and a clutch are mounted ready for use.
  • the lubrication system can be placed separately next to the mill gear or is also on the respective base plate, in which case two lubrication systems are used.
  • the entire unit of the first base plate is withdrawn from the mill area and laterally, i. shifted at right angles to the longitudinal axis of the first base plate in an area designated as a repair area.
  • the second base plate with the exchange gear is defined by a region designated as an application region, e.g. transversely to the longitudinal axis of the second base plate, moved and then passes through a longitudinal displacement in the mill area and under the grinding bowl.
  • the second base plate can be provided without a motor and the drive motor can be arranged on this second base plate if necessary.
