Definitions

  • the invention relates to a device for prevention the formation of blockages at the discharge of rust or Churning through large pieces of material, for example through large pieces of slag residues, especially on Ejection of sieve grates at an incinerator for lignite combustion.
  • the invention has for its object a device to create through which the aforementioned Difficulties will be eliminated.
  • the task is solved by a Device of the type mentioned in that under the discharge of the grate or the chute of an incinerator one by at least one 2-roller crusher formed shredding device is arranged.
  • This 2-roller crusher will fit exactly below the Sieve overflow used.
  • the crushing rollers are the 2-roller crusher overhung, the bearing on the side of the device facing away from the grate are located.
  • the bearings of the 2-roller crusher and the entire drive is therefore outside the warm range.
  • the device according to the invention can thereby be improved that the crushing area of the crushing rollers through at least one cooling water chamber to the storage area the 2-roller crusher is sealed.
  • the cooling water chamber forms another thermal protection for the Storage of the 2-roller crusher and their drive.
  • Another improvement of the device according to the invention is that above each 2-roller crusher several needle slides are provided. Means this needle pusher becomes the one during execution discharge of the combustion device open from maintenance work protected. For this it is only necessary to push the needle pusher over the discharge To push the combustion device.
  • the device shown in the drawing consists in essentially consisting of 2-roller crushers arranged side by side 1 with the associated drive 2, the 2-roller crusher 1 under the dropping of a - by dashed lines indicated - rust R arranged are.
  • the section shown in FIG The device shows two - of several - 2-roller crushers 1.
  • the left side of FIG. 2 shows a 2-roller crusher 1 in the area of the crushing rollers 3 and the right side of FIG. 2 a 2-roller crusher 1 in the area of the drive 2.
  • the crushing rollers 3 stored on the fly.
  • the camp 4 are on the Rust (R) side facing away from the outside Warm area.
  • a cooling water chamber 5 is provided between the crushing rollers 3 and the bearings 4, a cooling water chamber 5 is provided.
  • the 2-roller crusher 1 are in a manner not shown slidably arranged.
  • the needle slide 6 Above the 2-roller crusher 1, several are side by side arranged needle slide 6 provided the the discharge 7 then open during the maintenance work protect. Here, the needle slide 6 are in the position shown in the drawing. Before start the operation of the device, the needle slide 6th in the position 6 'indicated by dashed lines pushed.
