Embodiment Construction

[0010] In the accompanying drawings, 1 represents the casing of the decomposition device. A rotor 2 comprising blades 3 designed as substantially axially parallel slats is mounted inside the tubular housing 1 and coaxially with it. The drive motor is schematically indicated at 4 and drives the rotor 2 at a high rotational speed via a drive belt indicated at 5, thus causing the blades 3 at the point of delivery of the material to be decomposed to impinge on said material at high speed. The delivery takes place via a connection or conduit 6, through which the pumpable substance is introduced. The solid part of the substance is broken up by the impingement of the rotating blades or slats 3 on the solid. The discharge takes place via the discharge cone 7 at the cooling end 8 of the tubular rotary kiln, the fixing of which can be achieved in a particularly simple and stable manner via the flange 9 . Reference numeral 10 denotes a slide, by means of which the outlet opening can be...

Abstract

The invention relates to a method for introducing waste and/or alternative fuels into a clinker production method. The invention is characterized in that the starting materials are subjected, as sludges or in suspended form as a pumpable compound, to mechanical deagglomeration. The pumpable compound is ejected into rising pipes, pre-calcining furnaces and/or the rotary kiln. The device for carrying out the method is characterized by a tubular housing (1) having a rotor (2) that is received so that it can be rotated in relation to the axis of the tube in a substantially concentric manner and can be driven to rotate. Said rotor has rotor blades (3) that sweep over the space between the rotor shaft and the housing wall, a plurality of lines or openings (6, 7, 11, 14) being adjacent to the jacket of the tubular housing (1) and at least one line (6) being arranged together with the sludge supply and at least one being off-set in the circumferential direction.

Description

[0001] technology utilization [0002] The invention relates to a method for introducing waste and / or alternative fuels into a slag production process and a device for carrying out said method. Background technique [0003] In general, waste and alternative fuels exist in different states of matter and in different compositions. For example, it is known to convey used used tires to a suitable charging point in a tubular rotary kiln of a slag production plant by means of suitable conveying devices, wherein the corresponding plant parts must be adapted to the size of the used tires and to the The corresponding quality of the above-mentioned waste for proper transportation. Different solids are often present in different shapes, requiring conveying and feeding equipment to be specially adapted to the shape or to properly break down the material into loose material for delivery to the appropriate feeding point. However, for mechanically decomposed solids, the chemical compositio...
