Definitions

  • the invention relates to a device for producing a coal cake for coking, with an upwardly open molding box for receiving a ground coal with or without binder comprehensive bed and at least one acting on the bed in the mold box shock element for compacting and solidification of the bed to form a block ,
  • press punches for static compression of the co m comprises, wherein the pressing pressure exerting punches are each acted upon by a hammer, whose impulse on the ram on the bulk material is transferred.
  • the invention is based on the object, compared to the latter prior art constructively simplified device of the type mentioned, which is based on compression of the coal bed substantially only by pulse action and in terms of efficiency of coal compression and the achieved compression and solidification degree is significantly improved, to accomplish.
  • the problem solving device according to the invention is characterized by a provided for resting on the bed block block, which at least partially transmits the pulse of the rod element to the bed.
  • the stamp block according to the invention without even achieve a speed comparable to the impact speed of the rod element, possibly transmit the entire hammer pulse.
  • the reduced compared to the speed of the shock element speed of the punch block lateral material displacements during the impact process unlike would strike the shock element directly on the bed, largely avoided, and there is a concentrated in the direction of impact compression of the bulk material. Also, the adjacent side walls of the mold box are less loaded.
  • the impact element exerts a straight, preferably elastic impact on the stamp block, so that tilting movements of the stamp block with respect to the impact direction are avoided and the bulk material under the stamp block compacts into the depth.
  • the bulk of the facing punch surface of the punch block is greater than the punch block facing impact surface of the shock element or at most equal to this surface.
  • Stamp block can be coordinated so that the shock element loses its entire momentum when shock or block is thrown back on the stamp. In the latter case, only a part of the kinetic energy of the shock element is transmitted, which can be compensated if necessary by an increase of the impact frequency, the rebounding of the impact element counteracting an increase of the beat frequency.
  • the mass of the impact element may be less than or greater than the mass of the stamp block.
  • the stamp block optionally extends over the entire width of the stamp box. He could also extend over its entire length. In the latter case, it covers the entire surface of the bed and, if appropriate, several impact elements striking at different locations of the stamp block are provided, or at least one impact element can be moved in the longitudinal direction of the stamp block.
  • each impact element and one stamp block in each case form part of a machining unit which, in its entirety, can be moved both horizontally and vertically by a movement device.
  • facilities such as flexible strands, provided for the movable coupling of the stamp block to said processing unit, so that the Stamp block on the one hand can rest on the bulk material movable, but it is possible, on the other hand, to lift the processing unit including stamp block from the bed, for example, to introduce more bedding layers in the mold box.
  • the filling facing the stamp surface of the punch blocks on a compaction of the bed on a region concentrating around the shock axis shaping.
  • the stamp surface is shaped so that the bulk material when possible can not dodge perpendicular to the direction of impact.
  • the stamp surface may e.g. be concave or have a shape approximated to such a stamp surface.
  • the impact speed, the impact frequency and the mass of the impact element are variable, so that adaptation to different bulk material properties or other changes in the conditions for the compression, e.g. with increasing dumping height, can be accommodated.
  • the die block and the impact element have means for centering the impact element on the
  • stamp block on impact can have a control which comprises a sensor which detects the compacting action and a control which processes the sensor signal and which changes the momentum transmission by the impact element under the control of a desired compacting effect.
  • the sensor expediently detects a kinematic variable of the stamp block which is decisive for the compaction effect, for example the advance of the stamp block achieved by the momentum transfer or its maximum deceleration.
  • Fig. 2 shows the device of Fig. 1 in partial view from above
  • Hg. 3 another embodiment of a stamp block and a shock element of a device according to the invention.
  • a device shown schematically in a longitudinal section in FIG. 1 for producing a coal cake comprises an upwardly open molding box 1 for receiving a layered or uniquely introduced ground coal and, if appropriate, a binder 2.
  • the internal dimensions of the molding box are in the example shown 7 x 0.5 x 17 m, whereby the dimension 7m refers to the height.
  • a processing unit 3 arranged above the bed 7 comprises a drop hammer 4 and a punch block 5 provided for placement on the bed 2.
  • the processing unit 3 can be moved both vertically into the molding box 1 and out of the molding box as well as horizontally in the longitudinal direction of the opening 7 of the molding box 1.
  • the drop hammer 4 is movable separately relative to the processing unit 3 in the vertical direction. Devices for holding and guiding the punch block 5 on the processing unit 3 as well as drive means for the drop hammer 4 are not shown.
  • a plurality of processing units could be provided, possibly in such a number that the entire surface of the bed is completely covered by the stamp block of these processing units.
  • the stamp block 5 extends over the entire width of the opening 7, i. over the entire horizontal width of the molding box 1.
  • the molding box 1 is shown in FIG.
  • the processing unit 3 is to be sunk far into the depth of the molding box 1 by the movement device 6.
  • the movement device 6 further provides for horizontal displacements of the processing unit 3 in positions above compression sections 8.
  • the number of compression sections 8 is approximately equal to the quotient of the horizontal length of the molding box 1 and the length of the stamp block 5 in the longitudinal direction of the molding box 1.
  • the stamping block 5 Before activation of the drop hammer 4, the stamping block 5 is deposited in the approached by means of the moving device 6 compression section 8 by the processing unit 3 on the surface of the bed 2, so that it rests with its the bulkhead facing punch surface 9 against the carbon material. In this state, the fall hammer 4 hits each with a predetermined
  • a stamp block 5a shown in FIG. 3 has a slightly concave stamp face 9a, which ensures that the bulk material compaction concentrates on a region indicated by dashed lines 10 and 11 around the joint axis 11. By this measure, it can largely be avoided that material flows laterally into adjacent, already treated compression sections 8a and, with an increase in the compacted surface, again leads to a reduction of the degree of density in the adjacent compression sections 8a.
  • the stamp block 5a has a conical recess 13 on its side facing the drop hammer 3a, which confronts a corresponding end cone 14 of a drop hammer 4a. The recess 13 and the cone 14 form a case hammer 4a at Butt centering guide which ensures a straight joint without jamming of the punch block 5a.
