Description

Celem ulepszenia koksu hutniczego, o- trzymywanego z wegla koksowego, bo¬ gatego w gaz, zostaija dodawane do wegla koksowego Ar odki schu- dzajace, np. pyl koksowy, mial weglo¬ wy, antracyt lub tym podobne domieszki.Ponizszy wynalazek ma za zadanie wy¬ tworzyc sposób, przy którym mietylko zo¬ staja wydzielone w znany sposób ewentu¬ alne czesci, zawieraj aoe wiele popiolu, lecz zostaje takze umozliwione lzejsze mielenie i równomierniej sza domieszka srodka schu- dlzajacegoi. Wedlug wynalazku, sposób ten polega na tern, ze srodki schudzajace pod¬ legaja wspólnie z weglem bogatym w gaz znanemu przygotowaniu mokr^mechanicz- nemu.Nizej isa opisane dwie mozliwosci prze¬ prowadzenia tego sposobu.Wedlug fig. 1 dodaje sie srodek schu- dzajacy np, mial koksowy w suichym sta¬ nie do wegla, z moznoscia reguloiwania jego ilosci. Mial doprowadza sie w wózkach wywrotowych albo w inny sposób do szy¬ bu a, zaopatrzonego w elewator 6, zapomo- ca którego srodek schudzajacy doprowa¬ dza isie do zjbiarniika c dla wegla grubego, a stad mieszanine mialu weglowego i wegla surowego odprowadza sie elewatorem e do skrzynek plóczkowych. Regulowanie stosunku ilosciowego srodka schuidzajapego i wegla surowego od¬ bywa sie przy przedstawionym przykladzie albo zapomoca zmiany szybkosci elewatora lub tez zapomoca regulowania suwakiem d ilosci srodka schuidzajacego, doprowadza¬ nego do elewatora b.Wedlug fig. 2, wegiel surowy zostaje najpierw przemyty znanym sposobem w skrzyni osadowej /, podczas gdy mycie srodków schuidzajajcych odbywa isie oddziel¬ nie w malej skrzyni plóczkowej g.Przemyty mial koksowy przeprowadza sie w ilosciach dajacych sie regulowac, do przemytego wegla koksowego do przewietrz- ników h, skad tnuieszanitia ta d osia je sie zapamoca pompy, po ewientualnem przejsciu przez beben sitowy, do czerpa¬ ków plóczkiowych, gdzie odbywa sie od¬ wadnianie .miesizaniny weglowo-koksowej.Przy obu rodzajach wykonania sposo¬ bu, mieszanina wegla surowego i srodka schuidzajacego przechodzi wspólnie dluga droge, co daije rekojmie zupelnego zmie¬ szania. Srodek schudzaijacy zostaje roz¬ drabniany w stanie mokrym i wspólnie z weglem, przez co zostaje znacznie zmniej¬ szone zuzycie maszyny mielacej. Oprócz teigo zastaja wymyte, jak przy innych spo¬ sobach, bogate w popiól czesci srodka schudzajacego. PL PL PLIn order to improve blast furnace coke obtained from gas-rich coking coal, reducing agents, e.g. coke dust, coal dust, anthracite or similar admixtures, are added to the coking coal. The present invention is intended to create a method in which not only any parts containing a lot of ash are separated in a known manner, but also easier grinding and a more uniform admixture of the reducing agent are made possible. According to the invention, this method consists in the fact that the slimming agents are subjected together with the gas-rich coal to a known wet-mechanical preparation. Two possibilities for carrying out this method are described below. According to Fig. 1, the slimming agent, e.g., coke fines, is added to the coal in a dry state, with the possibility of regulating its quantity. The fines are fed in tipping cars or in another manner to shaft a, which is equipped with an elevator 6, by means of which the slimming agent is fed to the bin c for coarse coal, and from there the mixture of fines and raw coal is discharged through elevator e to the washing boxes. The regulation of the quantitative ratio of the cooling agent and raw coal is carried out in the presented example either by changing the elevator speed or by regulating the amount of cooling agent fed to the elevator b with a slider d. According to Fig. 2, the raw coal is first washed in a known manner in the settling box /, while the washing of cooling agents takes place separately in a small washing box g. The washed coke fines are transferred in adjustable quantities to the washed coking coal to the aerators h, from where the mixing is achieved by means of a pump, after optionally passing through a screen drum, to the washing buckets, where the mixture is dewatered. Coal-coke. In both methods, the mixture of raw coal and the slimming agent travels a long distance together, ensuring complete mixing. The slimming agent is ground in a wet state and together with the coal, which significantly reduces wear on the grinding machine. In addition, as in other methods, the ash-rich parts of the slimming agent are washed out. PL PL PL
