Definitions
- the invention relates to a device for dispensing pasty material with the material to be conveyed, preferably by means of a thick matter pump loadable to form a coherent line of conveyed goods, a delivery pipe provided with an ejection opening and with an axially parallel or coaxial through the discharge opening mandrel engaging in the pipe section for dividing the leaked strand of conveyed material.
- the invention further relates to a method for applying pasty Conveyed goods, in which the conveyed goods in the form of a strand with a Pipe section of a delivery line provided with the discharge opening is pressed, wherein the conveyed material strand is formed into a hollow strand in the pipe section which, after exiting through the discharge opening on the inside with a Pressure medium is applied.
- Devices of this type are used, for example, to drain water Enter sewage sludge for disposal in incinerators or on To spend landfills.
- a known device of a similar design has a cylindrical lance tube trained feeder from which through an entry opening in a furnace sticks out.
- the lance application is carried out under Pressure column of conveyed material at the end of the conveying line through the lance tube pressed.
- a pipe profile corresponding to this is formed Strand, which, depending on the consistency, in a coherent form or lumps through the pipe opening into the oven.
- sewage sludge introduced in the form of lumps or lumps is due to the low surface / volume ratio an increased supply from external energy to combustion. Another negative effect in this direction results from a locally uneven loading of the Oven.
- the object of the invention is a device and to develop a process for the discharge of pasty material to be conveyed, with simple means a spreadable shape and large area Distribution of the material to be conveyed is made possible.
- the invention is based on the idea of the incoming conveyor line in the area of the discharge opening with formation of scatterable Cut up bulk material and spread it in this form.
- the cathedral against the conveying direction pointing, engaging in the pipe section conical Dome tip, and that it is in an outside of the pipe section, preferably near the opening, pointing transversely to the conveying direction has nozzles which can be acted upon by a pressure medium.
- the preferably cylindrical dome has one against the conveying direction pointing conical mandrel tip. This will reduce the flow resistance and thus reduces the pressure losses in the flow of material to be conveyed.
- a further improvement in this regard is achieved if the pipe section is in its opening section close to the opening according to the local Mandrel cross-section has expanded inner cross-section and if the pipe section is flared in the area of the mandrel tip towards the discharge opening.
- the mandrel is on a protruding part, preferably projecting beyond the opening-side end of the pipe section Support structure arranged, which expediently at least three, preferably arranged at equal angular distances from one another, with her one radially oriented leg with the mandrel and with her other, axially parallel legs with the opening end of the pipe section has connected angle struts and thus for division of the incoming flow contributes.
- the nozzles with a through the mandrel and Support structure passed through, preferably via a jacket opening of the pipe section communicate with the pressure medium channel acted upon by the pressure medium.
- the pipe section advantageously has a near its arranged at the opening end, projecting radially outwards, flange ring that can be fastened with screws.
- the pressure medium supply can be continuous or pulsed and automatically controlled by the incoming flow become.
- the method according to the invention is advantageously for loading incinerators with sewage sludge used. Due to the size reduction and the large area Distribution of the sludge parts becomes self-reliance of the combustion process improved.
- the inventive method can also be used Advantage for spreading sewage sludge on land and use forestry or landfills.
- the device shown in the drawing is for Spreading of pasty materials, in particular thickened sewage sludge, in the form of bulk material determined a delivery line.
- the device 10 consists essentially of a an outlet 20 of a delivery line 12 by means of a pressure-tight pipe coupling 24 (sealing ring 22) flanged cylindrical pipe section 14 and one at a Support structure 15 attached coaxially by a Ejecting opening 30 engaging in the pipe section 14 Thorn 18th
- the pipe section 14 is based on its cylindrical Entrance 26 flared on a central section 28 and goes into a cylindrical end portion 32 with greater clear width over.
- the pipe section points in Region of the end portion 32 a radially outward projecting flange ring 34 with which it is connected to a Wall opening 36 of an incinerator by means of screws 35 is flanged.
- angle braces 16 are at equal angular intervals from one another arranged and are with their one, radially aligned Leg 38 with the outside of the pipe section 14 located end of the mandrel 18 and with its other, axially parallel leg 42 with the end face 54 of the pipe section 14 connected.
- the mandrel 18 engages approximately half the length of its cylindrical Shaft coaxially into the pipe section and carries one against the direction of conveyance, in the conical central section 28 of the pipe section 14, conical tip 44. Close to the opening The area outside the pipe section 14 has the mandrel 18 four in an annular zone 46 at the same angular distance arranged around the circumference, radially outwards directed nozzles 48, which with an axially through the Mandrel 18 and passed through one of the angle struts 16 Communicate pressure medium channel 50.
- the pressure medium channel 50 is through a jacket opening 56 through a longitudinal bore 52 of the tubular jacket through pressurized on the outside.
- the conveyor line 12 is with the help a thick matter pump with pasty material, for example with thickened sewage sludge, loaded.
- a thick matter pump with pasty material, for example with thickened sewage sludge, loaded.
- the pump pressure is the material to be conveyed, forming a connected conveyor line through the conveyor line 12 transported through to the pipe section 14.
- the strand cross section is through the inlet width 58 of the Pipe piece 14 determined.
- the conveyed material strand through the mandrel tip 44 impaled and thereby forming a hollow strand radially expanded.
- the invention relates to an apparatus 10 and a method for dispensing pasty material from a Conveying line 12, the material being conveyed through a Ejection opening 30 provided pipe section 14 pressed and formed into a hollow strand by means of a mandrel 18 becomes.
- the hollow strand is passed through after the passage compressed air is applied to the discharge opening 30 on the inside and divided it to form bulk material.
