of the last rotating drum, and the vote in the rotary motion of this drum is adjustable both for her to be ensured only to fire guide speed than any fluctuating also the direction of rotation within narrow limits averages. To be adjusted at the inlet end of the supply and does not have to be after the tip loading and mixing drum B , a burner 17 is arranged, loads aligned or on the different 5 with which a substoichiometric heating of the combustibility of all too different wastes is carried out interior space. Be supported by them. A further advantage of the inventive chiometric heating is a liquefaction, that the filling volume of the storage and mixing of the solid tars, oils and the like of the air-switched rotary drum. This offers the io for lack is not possible. The storage and mixing possibility of bunkering the accumulating waste drum B is provided at the outlet end with a conical transition 19 with simultaneous mixing with the already conical transition 19, which is carried over a waste before it is burned into the connection 20 downstream Rotating drum C long. This intermixing is brought about by the. In the area of the conical transition 19 the possibility of reversing the 15 according to the plan and possibly intensified in the adjacent inner area of the direction of rotation, since with such a rotating, storage and mixing drum B , a discharge direction reversal is also provided for the conveying direction of the invention screw 21, which the pretreated sealing in the conical narrowing outlet cases are transported evenly into the downstream rotary drum end of the storage and mixing drum arranged mel C.

Claims (2)

1 have 2 inhibiting projections. This results in patent claims: A sufficient residence time of the waste to be incinerated in the plant is achieved. 1. Device for incineration of waste, It is also known as from the magazine consisting of two independently driven, 5 "fuel-heat-power", 16 (1964), no. 8, p. 380, cascaded rotary drums, from or from the United States patent 2,963,996 the upstream rotary drum, which is connected to the combustion gases in the rotary kiln, is connected to the garbage collectors' loading lock, burns in direct current as well as in the Geder Processing of the waste and the counterflow in relation to the main direction of movement switched rotary drum whose incineration serves to lead io of the garbage. In application to industrial waste in liquid, the use of the known systems for doughing and solid form, thereby marked-burning of garbage prepares especially in the case that the upstream rotary drum - the disposal of industrial waste especially then has a storage and mixing drum (B. ) in a horizontal arrangement, which is technically and economically difficult, if the waste is incurred irregularly. Since the inlet side is provided with an oxygen-free burner (17) which can produce the irregularity of the accumulation of so-exhaust gas and probably on the type of waste accruing, which narrows conically on the outlet side and a location of origin or the temporal Distribution conveyor screw (21) and their filling volume as well as the respective amount. 20 The rotary drum (C) used to incinerate industrial waste is significantly larger than that of the downstream drum. Incinerators, however, are mostly on more 2. Apparatus according to claim 1, characterized in that the direction of rotation of the supply siert and in its capacity for a possible, but and mixing drum (B) is reversible. measured the maximum seizure that occurs only rarely. Abas seen from the fact that an intermittent commissioning would take the incinerator an unfavorable economic one There are also greater difficulties in terms of combustion technology. The invention relates to a device for processing. The object is to provide a device burning of waste, consisting of two independent 30 creating, which makes it possible, despite uneven, gig driven, series-connected rotary- discontinuous waste feed both according to Art drums, of which the upstream rotary current as well as according to the amount a uniform permanent emblem, to enable them to be operated in connection with a loading sluice in an incineration plant, The processing of the waste and the precautions must be taken to ensure that there are no unreasonably downstream Rotary drum the combustion of which serves up 35 dirt and residue approaches, in application to industrial waste in liquid, tread. In particular, those in refineries or doughy and firm form. petrochemicals incurred in similar operations Such a device is simpler from the Belgian waste, such as solid tars, oils and the like Patent 676,484 known. Way can be eliminated. In the known device there are two coaxial 40. To solve this problem, according to the invention, one after the other arranged, cylindrical rotary current in a device which is indicated at the beginning provided with a slight inclination of the axes, NEN type proposed that the upstream rotary die a drying and a combustion chamber drum a storage and mixing drum in the weaving. Both rotary drums have essentially a horizontal arrangement that aligns Diameter, the upstream rotary current 45 on the running side with an oxygen-free exhaust gas has a charging burner at its upper end and a ko device on the outlet side for the waste and is used by the narrowed track and has a discharge screw disposal of waste. For this it is with a double and its filling volume much larger than that of the walled jacket, through whose hollow rotary drum is connected downstream. In doing so, it proves Room hot gases for the purpose of heating the interior are particularly advantageous according to the invention when interior space can be passed through. This rotating drum determines the direction of rotation of the storage and mixing drum opens at its other, lower end in is reversible. the second rotary drum, which is equipped with the Forces through these measures, several advantages incineration of the dried waste required compared to the known systems for waste incineration devices is equipped. The waste achieved through-55. By training the upstream hikers the entire device from the loaded rotary drum to a storage and mixing drum device to the discharge device at the bottom, in which no combustion takes place yet lying end of the combustion chamber in the direct prayer, which can be performed according to any schedule Pass-through and in countercurrent to the flames sent with the waste as well as enabled tion and the hot gas flow given with it. 60 an intensive mixing of the various Rotary kilns for waste incineration are also incidents with the consequence of a homogenization of the Abderweitig known, for example from the German Fallgutes. In the interaction of this mixed effect Utility model 1 898 016, in which one for the control with the speed control of the supply and mixed combustion Above all, the loading of the generation system is described, the specialty of which in 65 downstream rotors used for combustion special shape of the firebricks drum with one in composition and quantity which is used to line the interior of the rotary kiln - an even flow of waste wall to be incinerated are used and which the good conveyance achieves well. Moreover, the dimensioning needs
