Definitions

  • This invention relates to a gearing and overloading safety system for worm conveying of solid fuel.
  • the present invention is especially well suited for stoker furnaces needing very high gear ratios and rapid change of gears. This may be desirable in the case of various volume/weight ratios.
  • the known techniques suffer the drawback that the chain is caused to break or that the motor seizes as a consequence of a possible blocking of the worm.
  • the purpose of the present invention is to provide an improved stoker system.
  • a system of simple construction which has a high gear ratio with a minimum of power loss, and which has a spring for adjustment of maximum load, and where the said spring at the same time acts as an overload safety device for the worm conveyor.
  • the novelty according to the invention is the use of a crank movement to pull the idling bearings which pull the worm a distance forward, and on the return stroke the worm comes to a standstill.
  • a safety arrangement in the form of a compres ⁇ sion spring is to be used in push rotation.
  • the drive arm is prolonged so that the spring is mounted on the other side of the gear arm. which thus makes the spring function as a compression spring.
  • a rapid change in the gearing can be effected by changing the length of the drive arm, either by moving the push/pull rod into holes or infinitely variably in a slit.
  • the overload safety device can, in principle, run endlessly without damage to vital parts.
  • the result will be a functional heating plant, which is simple of construction and has a conveyor system consisting of few components.
  • Fig. 1 shows a fuel hopper with a stoker conveyor system. Examples of embodiment.
  • Fig. 1 shows the stoker conveyor system mounted on a fuel hopper, and which consists of an idling bearing on which is mounted a gear arm and a drive arm with an overload safety device.
  • the drive arm with the overload safety device (1) is loosely mounted on the gear change arm (2). This makes it possible to change the gearing, which will cause a change in the speed of rotation of the stoker worm body (4).
  • the gear change arm (2) is built integral with an idling bearing (3), which is mounted on the stoker worm (4) itself.
  • the whole stoker conveyor system is driven by an electric motor (5).
  • the electric motor (5) transmits the drive to the drive arm (1) via an eccentric disk (6).
  • the drive arm (1) is of a cylindrical construction with an overload spring (7), and by means of the tensioner device (8) it is possible to change the maximum load of the overload safety device.
