1 Patentni zahtevki 1. Priprava za ravnanje s prašnato snovjo v tekočinskem koritu, kije pomešana s produkti, ki se ne dajo splaviti, pri čemer je priprava opremljena s sistemom za zaznavanje zamašitve in obsega: a) sredstvo (13) za nabiranje prašnate snovi; b) sredstvo za splavitev, ki obsega keson (14) iz dveh delov: zgornjega dela, ki je povezan z enim svojih koncev z nabiralnim sredstvom (13) s pomočjo dovajalne cevi (15) in z nasprotnim koncem s cevjo (16) za uravnovešanje, in spodnjega dela za dovajanje plina za splavitev, pri čemer je ta razdeljen v dva neodvisna prostora (18,20), ki se jima dovaja plin za splavitev preko iste cevi (22), ki se razdeli v dva kraka (23 in 24), in sta ločena od zgornjega dela z dvema poroznima stenama (19 in 21), pri čemer je prva porozna stena (19) nameščena pod dovajalno cevjo in v sosednjem področju in je druga porozna stena (21) nameščena pod cevjo za uravnovešanje in v sosednjem področju; c) sredstvo za odstranjevanje prašnate snovi, ki je nameščeno v zgornjem delu kesona na koncu, ki leži nasproti dovajalni cevi; označena s tem, da je prva porozna stena (19) nameščena na vodoravnem nivoju, ki je nižji od le-tega za drugo porozno steno (21), in da je priprava opremljena z merilnimi sredstvi in sredstvi za beleženje tekom časa razlike tlakov, ki vladajo v vsakem izmed dveh neodvisnih prostorov (18) in (20).A device for handling a powdered substance in a liquid bed, mixed with non-abrasive products, wherein the device is provided with a clogging detection system and comprises: a) means for collecting a powdered substance; b) a launching means comprising a casing (14) of two parts: an upper part which is connected to one of its ends by a picking means (13) by means of a feed tube (15) and a counter-end with a balancing tube (16) , and a lower part for supplying a gas for launching, whereby it is divided into two independent spaces (18,20) which are supplied to the launching gas via the same tube (22), which is divided into two arms (23 and 24) , and are separated from the upper part by two porous walls (19 and 21), wherein the first porous wall (19) is located under the feed tube and in the adjacent region, and the second porous wall (21) is positioned under the balancing tube and in the adjacent field; c) means for removing the powdered substance located in the upper end of the hopper at the end lying opposite the feed tube; characterized in that the first porous wall (19) is located at a horizontal level that is lower than the latter for the second porous wall (21), and that the device is provided with measuring means and recording means during the time of the pressure difference they rule in each of the two independent spaces (18) and (20).2. Priprava po zahtevku 1, označena s tem, da je sredstvo za odstranjevanje splavljenega produkta sestavljeno iz izstopnega ustja (17) za prašnato snov, ki je nameščeno neposredno nad porozno steno ob cevi za uravnovešanje. 2Device according to claim 1, characterized in that the means for removing the abandoned product is composed of an outlet orifice (17) for the powder material located directly above the porous wall along the balancing tube. 23. Priprava po zahtevku 1, označena s tem, da je opremljena s sistemom za vibriranje, ki lahko porozni steni podeli izmenjujoče gibanje, s sistemom sit, ki dopuščajo odstranjevanje trdne faze, ki se ni splavila in se dekantira na najnižjem delu porozne stene, in daje sredstvo za odstranjevanje splavljenega produkta sestavljeno iz preliva, kije nameščen na zgornjem delu kesona nasproti tistemu od dovajalne cevi.Device according to claim 1, characterized in that it is provided with a vibration system capable of dividing the alternating movement of the porous wall with a sit system that allows the removal of a solid phase which has not split and decanted on the lowest part of the porous wall, and the means for removing the dismantled product is composed of an overflow which is located on the upper part of the casson opposite to that of the feed pipe.4. Priprava po zahtevku 1, označena s tem, da je sredstvo za odstranjevanje splavljenega produkta sestavljeno iz: a) dovajalne cevi (39) za plin pri povečanem tlaku, ki se končuje z injektorjem (40) v zgornjem delu kesona nad porozno steno nasproti dovajalni cevi, b) navpične prenosne cevi (41), kije na svojem spodnjem delu opremljena z ustjem (42), kije nameščeno navpično in nad injektorjem.Device according to claim 1, characterized in that the means for removing the depleted product is comprised of: a) a gas supply gas supply pipe (39) with an increased pressure ending with the injector (40) in the upper part of the cupola above the porous wall opposite b) vertical transmission pipes (41), which are provided with an orifice (42) on their lower part, which is mounted vertically and above the injector.5. Postopek za zaznavanje zamašitve, ki uporablja pripravo po kateremkoli izmed zahtevkov 1 do 4, označen s tem, da se neprestano nadzira povečanje tlačne razlike med dvema neodvisnima protominama spodnjega dela kesona in da se pristopi k čiščenju porozne stene, ko ta tlačna razlika preseže vnaprej določeno predvideno vrednost.A method for detecting the clogging using the device according to any one of claims 1 to 4, characterized in that the increase in the pressure difference between the two independent protons of the lower part of the cassone is constantly monitored and that the porous wall is approaching when the pressure difference is exceeded predetermined predicted value.
