Definitions

  • the invention relates to a water nozzle for dust control, in particular on cutting rollers, essentially consisting of a housing which can be screwed into a water supply line and has a collecting bore on the water inlet side and a central bore of small diameter on the water outlet side.
  • a water nozzle is shown, in which in the collecting hole on the water inlet side in front of the nozzle to prevent a possible A strainer is used to block the nozzle due to contamination. It can be assumed that the corresponding impurities are collected within the sieve body, but that the content of the sieve body ultimately means that an adequate atomization of water can no longer be carried out. The exchange of the screen body is associated with corresponding downtimes of the extraction machine.
  • the invention has now set itself the task of creating a water nozzle for dust control, in particular on cutting rollers, which avoids the blockages while avoiding the above-mentioned disadvantages and largely guarantees the functionality of the nozzles and which is also simple and inexpensive to manufacture.
  • the collecting bore is divided into two sections, in that a stepped guide sleeve with a piston which is stepped several times in the axial direction and can be preloaded via a spring is arranged in the section of the receiving bore of the housing and can be screwed into it, and that the Guide sleeve consists of a channel-like inlet on the water inlet side and a subsequent extension and the piston arranged in the guide sleeve has a slight widening in the inlet and a larger widening within the extension, the widening of the piston forming a narrowed annular gap with the inlet when water enters.
  • the guide sleeve consists of a channel-like feed on the water inlet side and a subsequent extension and the piston arranged in the guide sleeve has a slight widening in the feed and a strong widening within the extension.
  • the technical advantage of the invention is to be seen in particular in the fact that the high cost of downtimes, which have to be carried out by the constantly necessary cleaning of the water nozzles, are substantially reduced since the nozzles according to the invention are equipped with a self-cleaning device.
  • the water nozzle shown in section in the drawing consists essentially of a housing 1 having an external thread 3, in which a central bore is made.
  • the collecting hole is divided into two sections 2 and 17 with different diameters.
  • a guide sleeve 5 can be screwed into section 2 of the collecting bore by means of a further thread 4.
  • the thread 3 is provided for connection to a water supply line.
  • the guide sleeve 5 has a narrowed channel-like guide 7 on the water inlet side and then an extension 8.
  • the extension 8 merges into the section 17 within the housing 1.
  • the section 17 as part of the central bore is provided with a step 15 in relation to the extension 8.
  • a multiply graduated piston 6 is arranged within the guide sleeve 5.
  • the piston 6 At its upper end arranged on the water inlet side, the piston 6 has a slight reinforcement 9 and a larger reinforcement within the extension 8 10 on.
  • the piston 6 At the lower end of the piston 6 on the water outlet side, the piston 6 has a piston stub 14.
  • the piston 6 can be pretensioned by means of a spiral-shaped spring 13.
  • In the reinforcement 10 there is a horizontal bore 11 and a bore 12 extending vertically through the piston stub 14.
  • the spring 13 is mounted within the section 17 in the step 16, which is designed as an abutment.
  • the upper end of the spring is guided through the piston stub 14.
  • the central bore 18 connects to the section 17 on the water outlet side.
