Definitions

  • the invention relates to a device for smuggling a hot flour-like material, in particular a hot cement raw meal stream in the cyclone levitation gas heat exchanger system of a plant for the production of cement clinker from raw meal, with a Lock housing with upper good entry opening, lower good exit opening and at least one arranged between the two openings Pendulum flap.
  • Plants for the production of cement clinker from raw cement powder according to the dry process have a raw meal preheater, which in usually consists of a cyclone suspended gas heat exchanger system, where the raw flour is given up where it is successively the cyclone stages in combined cocurrent / countercurrent Exhaust gas from a precalcination stage travels to the bottom Cyclone separated from the hot exhaust gas flow and as a highly precalcined Cement raw meal in the inlet chamber of the rotary kiln to be introduced, in whose sintering zone it burned to cement clinker becomes.
  • a raw meal preheater which in usually consists of a cyclone suspended gas heat exchanger system, where the raw flour is given up where it is successively the cyclone stages in combined cocurrent / countercurrent Exhaust gas from a precalcination stage travels to the bottom Cyclone separated from the hot exhaust gas flow and as a highly precalcined Cement raw meal in the inlet chamber of the rotary kiln
  • heated raw meal is in each case vertical or inclined flour down pipes or raw meal chutes under the influence the gravity in the respective exhaust pipe section or the precalcined raw meal from the lowest cyclone level to the Rotary kiln inlet chamber introduced.
  • pendulum locks or flap boxes also double swing locks installed, in which one or two weight-loaded pendulum flaps are integrated, which have the task of holding back the hot gas flow and on the other hand after a certain solid loading by swinging open the flaps through the hot raw meal stream down to let the flour fall pipe through
  • These swing flaps are of high mechanical, chemical and thermal stress and thus a high thermochemical and exposed to abrasive wear.
  • the pendulum flaps were previously formed in one piece, d. H. in the event of wear the entire swing flap removed and repaired accordingly or can be exchanged for a new swing flap.
  • the invention has for its object to smuggling or distribution or allocation of a hot flour-like material stream in particular a device such as a pendulum lock for cement plants create their pendulum flap or their pendulum flaps in the event of wear easy and inexpensive to repair or replace is or are.
  • the at least one swing flap arranged in the lock housing is not in one piece, but is at least in two parts and two-part design consisting of an upper hanging part and a lower wear part composed especially of other material is.
  • the upper hanging part which is tough heat-resistant material
  • the lower wear part the pendulum flap, which is preferably made of a wear-resistant heat resistant material is stiff, d. H. Not articulated but releasably connected.
  • the size of the wearing part corresponds to that lower swing flap area, of the periodically pent up and released Hot flour flow in contact with the hot abrasive flour flow comes.
  • the upper hanging part and the lower wearing part others Material can expand differently and arise no thermal stress. In the event of wear, only the Connection between the upper suspension part and the lower wear part solved and the wearing part is repaired or against new part replaced. Occasionally, the materials of the two Flap parts can also be designed the same or of the same type.
  • the releasable connection between the upper suspension part and the lower wear part be designed like a stiff or stiffened joint.
  • the upper suspension part and the lower wear part of the pendulum flap on the adjacent sides in the manner of a tongue and groove connection interlock, with the interlocking flap parts by corresponding aligned Through openings two spaced apart, parallel to Swiveling axis of the pendulum flap removably led bolts are.
  • the upper suspension part of the swing flap can be made from a cast body consist of a shaft journal on both sides of the top is cast on.
  • the two shaft journals of the upper suspension part then form the pivot axis or pendulum axis of the weight-loaded Pendulum flap.
  • the hanging part can also be used as a welded construction be carried out.
  • the lower wear part can also be designed as a cast part, welded part or ceramic part.
  • At least the side of the stressed wear facing away from the flow of material to be Swing flap with a fireproof and wear-resistant Material be coated.
  • the two parts of the pendulum flap or at least the lower wear part as a composite body be formed consisting of a flat metallic Basic body, on the web of a metallic grid-shaped grate are arranged, the openings with a heat-resistant ceramic mass are filled out.
  • One or both parts of the flap can also be on one or both surfaces be provided with another wear protection layer.
  • FIG. 1 is in the sloping raw meal slide or flour down pipe 10, through which a hot raw meal stream under the influence of gravity 11 is promoted from top to bottom, a pendulum lock installed with a housing 12 with an upper good entry opening 13 and lower good exit opening 14 and with a between two openings arranged pendulum flap 15, which as a result of Weight load 16 in an oblique, the raw meal 11 shut off Position is held.
  • the between the individual cyclone stages of the cyclone levitation gas heat exchanger system of a cement clinker production line built-in pendulum lock with its weight-loaded Pendulum flap 15 has the task, on the one hand, of the Principle of hot exhaust gas flow rising from bottom to top in each case withhold and on the other hand after a certain solid loading by swinging the pendulum flap 15 to the right the periodically dammed up raw meal stream 11 downwards to pass through the flour drop line 10a.
  • the pendulum flap 15 is formed at least in two parts and an upper suspension part 15a and a lower one Wear part 15b assembled.
  • the upper suspension part 15a of the pendulum flap made of a tough heat-resistant material, e.g. B. from one Cast body exist, on the top of each one Shaft journal 17 is cast on, so that the two shaft journals 17 the pivot axis of the pendulum flap 15 in the flap housing 12 form.
  • the lower flap part 15b consists, for. B. from a wear-resistant heat-resistant material.
  • Upper suspension part 15a and lower wear part 15b of the swing flap are stiff, d. H. not articulated, but releasably connected.
  • upper suspension part 15a and the lower wear part 15b of the swing flap on the adjacent sides in the manner of a tongue and groove connection into each other, with the interlocking in the toothing area Flap parts by corresponding aligned Through openings two spaced apart, parallel to Pivot axis 17 of the pendulum flap pin 18 and 19 releasable are passed through. If the pendulum flap becomes worn only the two bolts 18 and 19 loosened, and the lower wear part 15b is repaired after its removal or by a new wear part replaced.
  • the invention allows a strict separation of functions between the Flap suspension part 15a made of a tough heat-resistant material and the flap wear part 15b from a brittle and hard material and yet both flap parts are coupled together, without thermal stress.
  • the one to be smuggled Gutstrom 11 side of the pendulum flap facing away in the conveying direction coated with a fire-resistant and wear-resistant material his.
  • the two parts 15a and 15b the pendulum flap be formed as a composite body consisting of a flat metallic base, on which as a reinforcement Webs 20 of a metallic grid-shaped grate are arranged, whose openings are filled with a heat-resistant ceramic mass 21 are.
  • the two pendulum flap parts can also be used as coolant Hollow body can be formed, so that an additional external Cooling the swing flap is made possible.
  • the invention is applicable not only to swing flaps, but also for so-called impact slides, which are used across cement plants a hot gas line coming from the rotary kiln is installed and have the task of preheated raw cement meal from the side is introduced into the hot gas line, depending on the baffle slide position to distribute or evenly over the hot gas cross section suspend.
