Definitions

  • the invention relates to a briquetting press, in particular for wood shavings, sawdust and wood dust, with a conical feed hopper in which a conveyor shaft is provided, which is driven from below via a universal joint, with an intermittently driven pre-pressing screw, with a press piston and a cylinder-like press jacket.
  • a briquetting press in particular for metal chips, is published in DE-C-23 13 343.
  • a chip holder pierces a chip container, a briquette being formed in a die. By moving the chip container, the die is removed from an end plate and the briquette is ejected from the press ram so that it can fall off.
  • CH-A-628 837 relates to a briquetting press for waste heating material.
  • a fixed funnel is arranged above a rotary table provided with press cylinder jackets, which has a horizontal feed screw and a vertically acting pre-press piston which stuffs the press cylinder jackets.
  • An upper press piston and a lower counter-piston act diametrically opposite the pre-press piston, the upper press piston pushing the briquette with the counter-piston into an output ring, from which it falls on an inclined plane.
  • DE-A-30 49 276 proposes a briquetting press for use in the peat, coal and coking industry for the production of heating briquettes and for use in agriculture for the production of briquettes from coarse feed for feeding cattle.
  • a briquetting press for use in the peat, coal and coking industry for the production of heating briquettes and for use in agriculture for the production of briquettes from coarse feed for feeding cattle.
  • two pre-press cylinders designed in the opposite direction of rotation via Maltese crosses.
  • the teeth of these two pressing organs delimit a cylindrical pre-pressing space in their paired comparison.
  • the pre-pressed briquette is pressed through a reciprocating ram through a conical constriction and an ejection channel.
  • the object of the invention is to achieve a constant strength of the briquettes by regulating the pressing resistance with a relatively small motor power and reduced energy consumption as well as with a simple construction.
  • a briquetting press which is characterized in that the press jacket is divided in the longitudinal direction and has two shell halves, the lower shell half being firmly connected to the housing of the press plunger, that the upper shell half, close to the inlet connection and downstream the pre-press screw is provided with a joint, so that this shell half can be pivoted upward to expand the flow cross-section, and that the outer end of the upper shell half is operatively connected to a hydraulically actuated stop piston, so that the upper shell half is raised when the pressure of the plunger exceeds a predetermined value.
  • FIG. 1 shows a schematically drawn cross section through the briquetting press
  • FIG. 2 shows a view in the direction X of the ejection opening of the press jacket.
  • the briquetting press shown has a conical feed hopper 1 in which a conveyor shaft 3 provided with blades 2 is installed. This is driven from below via a bevel gear 4 and a universal joint 5.
  • a conical feed hopper 1 in which a conveyor shaft 3 provided with blades 2 is installed. This is driven from below via a bevel gear 4 and a universal joint 5.
  • an intermittently driven pre-press screw 6 is provided, which brings the wood residues 8 to be formed into briquettes 7, for example shavings, sawdust and wood dust, in an oblique direction through a nozzle 9 into a press jacket 10.
  • a press piston 13 formed with a rear shoulder 12 is actuated by a press cylinder 11. With the forward Stroke, the press piston 13 presses the material 8 supplied by the screw 6 into the press jacket 10, so that four briquettes 7 come to lie one behind the other in this.
  • the press jacket 10 has two shell halves 10a, 10b separated in the longitudinal center thereof.
  • the lower half shell 10a is firmly connected to the housing 14 of the plunger 13.
  • the upper shell half 10b is provided near the inlet connection 9 with a joint 15, the
  • Pivot axis is transverse to the longitudinal axis of the press casing 10.
  • the upper shell half 10b can thus be pivoted upwards about the joint 15, the through-flow cross section for the briquettes 7 being expanded and the pressing pressure being reduced.
  • a hydraulically operated stop piston 16 acts on the outer end of the upper shell half 10b (FIG. 2). This is in operative connection with a solenoid valve (not shown in the drawing) and a pressure switch 17 connected to the press cylinder 11.
  • the press piston 13 presses the material 8 together with approximately 90% of its maximum pressing force. If the pressing force rises above this value, the stop bolt 16 is relaxed via the pressure switch 17, so that the upper shell half 10b can swing out somewhat upwards. As a result, the pressing resistance on the piston 13 is reduced and the outermost briquette 7 can be ejected without problems.
  • a limit switch 18 effects a backward stroke of the plunger 13.
  • the pre-press screw 6 is driven by an oil motor.
  • the stroke direction is reversed with a pressure switch, not shown in the drawing.
  • the solenoid valve maintains the pressure on the stop piston 16 until the discharge pressure of the piston 13 exceeds its predetermined value.
  • the pivotable upper shell half 10b which is under a certain adjustable pressure of the plunger 16, brings about a constant strength of the briquettes with different wood waste materials (chips, sawdust, wood dust), a trouble-free ejection of the briquettes 7 and a reduced energy consumption.

Abstract

Dans une presse à briquettes, le manteau de presse (10) entourant les briquettes (7) à expulser est d'une configuration empêchant la résistance d'expulsion de dépasser une valeur prédéterminée de façon à pouvoir obtenir une solidité constante de la briquette (7) même à partir de différents matériaux de déchets de bois et à pouvoir maintenir à un niveau bas la puissance requise du moteur. A cet effet, le manteau de presse (10) est divisé dans le sens longitudinal. La moitié supérieure de l'enveloppe (10b) peut pivoter vers le haut autour d'une articulation (15) aussitôt qu'un boulon de butée (16) agissant sur l'extrémité extérieure de cette moitié d'enveloppe (10b) se retire à la suite d'une pression trop importante du piston de compression (13).
