Definitions

  • the invention relates to a device for briquetting plant material, in particular stalk material, according to the preamble of claim 1.
  • a straw briquetting device with a screw compactor whose rotatably drivable screw has at its front end in the conveying direction a conical tapering in the conveying direction, which is defined by several turns of two projecting from a conical screw core helical spiral.
  • the conical section of the otherwise cylindrical screw projects into a conical compression chamber of a screw housing, into which the screw, which is mounted on the fly, projects.
  • a hopper for the straw to be briquetted is attached, which is compacted by the rotating screw in the conical screw section and pressed out via an outlet opening at the tapered end of the conical surface of the screw housing.
  • the pressure of the conical screw compressor can be controlled via a tubular press die with a variable outlet cross section, which adjoins the outlet opening of the conical surface.
  • the straw to be briquetted is strongly compressed under the pressure of the conical screw compactor, whereby it heats up and, due to its lignin content in the heat, is baked into a straw cake that is not very flowable even when warm. Since there may be congestion in particular at the transition from the inner cone of the screw housing to the press die, which block the outlet opening of the conical screw compressor, a press ram is arranged axially displaceably in the screw of the device known from DE-OS 34 22 658, which periodically moves in the screw housing accumulating compacted straw is pushed out into the press die.
  • the lignin content of the straw not only enables briquetting, but also sticks the press ram, which is displaceably guided in the screw, to immobility with the screw.
  • the known device can thus only be operated in comparatively short operating intervals before it has to be dismantled and cleaned.
  • the invention is based on a guide bar which is arranged on the inner cone surface of the screw housing of the known device and projects toward the screw.
  • a plurality of guide strips extending in the axial direction of the screw are provided on the inner cone jacket, by means of which the twisting of the straw cake is to be prevented during compaction.
  • the invention proceeds from this principle and allows the straw cake to rotate in the cone screw compactor.
  • the guide bar encloses the screw in the form of a conical spiral with a direction opposite to that of the screw, whereby the guide bar screws the rotating straw cake to the outlet opening of the inner cone of the screw housing and ensures a smooth and trouble-free discharge to the press die. Press rams or the like, which are provided in the known device, can thus be omitted.
  • a guide bar is to be understood as an elongated element which is capable of screwing onto the compacted, rotating crop in the conveying direction.
  • the element can in particular also have the shape of a rib or a web, which is also integrally formed on the worm housing, for example by grooves in the worm housing.
  • the device according to the invention is suitable for briquetting plant materials of all types and consistency, in particular also wood waste, such as sawdust and wood shavings; but it is particularly especially used for briquetting stalks, especially dry stalks, such as straw.
  • the inner conical surface of the screw housing normally extends beyond the screw in the conveying direction of the screw. In this way, a tapering chamber remains in the screw housing in front of the screw at the entrance to the pressing die, through which the pressing pressure of the screw must drive the already compacted straw. This is considerably facilitated if the guide bar extends into the area of the inner cone surface that extends beyond the screw and expediently reaches as far as the outlet opening. It is understood that the cone helix can optionally also be designed as a multi-start cone helix consisting of several guide strips.
  • the cone screw compressor is assigned a coaxial screw compressor, which is fed with the straw material from above via a filling funnel.
  • the screws of the cone screw compressor and the screw pre-compressor have a common screw core, so that there is a considerable overall length of the device.
  • the screw of the conical screw compressor has a conical shape over almost its entire conveying length and the screw pre-compressor with a screw axis running transversely, in particular perpendicularly, to the screw axis of the conical screw compressor directly to an inlet opening in the Screw housing of the cone screw compressor connects.
  • the resulting comparatively compact arrangement can be further reduced in favor of downsizing the screw pre-compressor if, on the side of the screw pre-compressor on which the outlet opening of the cone screw compressor is located, a pre-press roller unit with at least two axially parallel to one another and to the screw axis of the screw pre-compressor rotatably driven pre-pressing rollers is arranged, which press the straw between them and push them into an inlet opening of the screw pre-compressor transversely to its screw axis.
  • the straw to be compacted is fed on the side of the pre-press roller unit facing away from the screw pre-compactor, for example via a conveyor belt, and passes through an essentially U-shaped path during the transport and compacting process, on which the respective processing components can be arranged relatively close together.
  • the two pre-press rollers can be arranged axially parallel one above the other and, if necessary, be adjustable relative to one another, and, depending on their direction of rotation, a rotationally driven blow bar roller can also provide either an additional pre-press effect or a combing effect that equalizes the loading rate.
  • a ring part is arranged in a preferred embodiment between the outlet opening of the conical compression chamber of the conical screw compressor and the pressing die adjoining the outlet opening in the conveying direction, on the inner jacket of which a plurality of degassing channels open to the environment.
  • the degassing channels are capillary channels with a very small width, for example of the order of a tenth of a millimeter, through which the developing steam can escape.
  • the ring part is expediently a component produced using spark erosion technology.
  • the degassing channels should essentially only allow the passage of steam and possibly also fine dust. They can be in the form of axially extending slots which merge into radially overlying, axially extending, wider discharge channels in order to improve the vapor discharge. While the degassing ducts are closed off axially on both ends of the ring part by adjacent surfaces of adjacent components, the discharge ducts are open to the surroundings on at least one end side of the ring part, for which purpose, in the adjacent component, for example the screw housing of the conical screw compressor, an annular duct open to the surroundings can be incorporated.
  • the ring part In order to be able to manufacture the ring part more easily, it is expediently not an integral part of the screw housing or the press die, but rather sits as a separate component in a chamber of a die tube of the press die open towards the screw housing of the conical screw compressor.
  • the adjoining to the outlet opening of the cone screw compressor of the device known from DE-OS 34 22 658 press die has an essentially coaxial to the cone axis of the cone screw compressor, divided by two axial slots in two halves, the outlet cross section through a radially acting, hydraulic Pliers can be varied.
  • the outlet cross section of such a die can only be adjusted relatively inaccurately.
  • a comparatively high hydraulic pressure must be constantly applied to adjust the outlet cross section.
  • a more precise adjustment of the outlet cross-section with reduced actuating forces can be achieved if wedge surfaces are provided on the outside of the die tube, which is divided into radially movable tongues by the axially extending slots, which jointly encloses a clamping ring.
  • the clamping ring and the die tube are axially movably guided relative to one another and are biased against one another in the axial direction by springs.
  • the actuator of the wedge gear formed by the clamping ring and the wedge surfaces adjusts the clamping ring against the force of the springs.
  • the angle of inclination of the wedge surfaces is preferably chosen so that self-locking occurs, so that the actuator no longer has to absorb the baling pressure of the straw.
  • the actuating force to be exerted by the actuator can be reduced even further if the springs pretension the clamping ring and the die tube against one another in the direction of a narrowing of the outlet cross section of the press die.
  • This design of the pressing die can also be used with other straw briquetting devices than the device explained above.
  • the die tube is firmly connected to the screw housing and a machine base of the conical screw compressor.
  • Several springs are distributed around the circumference of the die tube, which are supported on a support flange of the die tube on the one hand and on heads of axially extending tie rods which are fixedly connected to the press die or to the machine base.
  • Such a press die needs only a few components.
  • the die tube and the screw housing of the conical screw compressor form a structural unit which is guided so as to be movable in the axial direction of the screw relative to the screw and the machine base.
  • This variant has the advantage that not only the outlet cross section of the die can be varied, but also the free internal volume of the conical screw compressor.
  • the wedge surfaces are arranged so that when the outlet cross section of the press die is widened, the screw housing is removed from the screw in the conveying direction thereof.
  • the pressure in the compressor chamber thus decreases immediately due to the adjustment movement due to the expansion of the compressor chamber and instantly supports the relief effect of the opening die. In the opposite case, the pressure rise in the compressor chamber is accelerated when the die is closed.
  • a pressing pressure sensor is expediently assigned to the conical screw compressor, and the actuator can be controlled as a function of the pressing pressure sensor.
  • the baling pressure sensor can respond to the actual pressure acting between the worm and the worm housing, but is easier to implement if it senses the baling pressure via an indirect parameter. for example via the drive torque of the screw of the conical screw compressor.
  • the material stowed in the matrix tube is pushed out at the end of the matrix tube opposite the outlet opening by the delivery pressure of the conical screw compressor.
  • the die tube must therefore be so long that the compacted material has cooled to a solid mass at its outlet end. This requires comparatively long die tubes.
  • a turret press die is arranged in front of the outlet opening of the conical screw compressor, the die tubes arranged on a common, rotatably mounted turret head can be individually aligned in succession to the outlet opening.
  • the turret press die is assigned an ejection station which is offset from the outlet opening in the circumferential direction of the turret head.
  • the turret press die comprises a plurality of die tubes, which are dimensioned exclusively from the point of view of the briquette formation and the achievement of a sufficiently high retaining pressure of the conical screw compressor, which facilitates the control of the briquetting process, since the compression process takes place independently of the ejection step.
  • the turret has a fixed closure wall axially opposite the outlet opening of the conical screw compressor, which at least ver the respective aligned to the outlet die tube on the side facing away from the outlet opening ver closes.
  • the matrix tube forms, together with the closure wall, a chamber into which the screw compressor feeds and which preferably already has the final size of the briquettes to be produced.
  • the opening edge of each die tube facing the outlet opening expediently forms an annular knife-edge which shears off the strand of material emerging from the outlet opening of the conical screw compressor during the indexing movement of the turret head.
  • the die tubes are arranged at a distance from one another on the turret head in the circumferential direction and form radially open cooling air passages between them.
  • a cooling air blower conveys cooling air from radially inside to radially outside through these cooling air passages, so that the briquetted material can cool down during the gradual approach to the ejection station.
  • the ejection station is angularly offset in the conveying direction by the largest possible number of die tubes against the position aligned with the outlet opening of the conical screw compressor.
  • an optionally hydraulically driven ratchet step mechanism For the step-by-step drive of the turret head, an optionally hydraulically driven ratchet step mechanism has proven to be suitable.
  • FIG. 1 and 2 show a straw briquetting device with which loosely poured straw, which has not previously been comminuted or ground, can be compacted into compact straw briquettes of high density of at least 0.5 kg / dm 3.
  • the straw is placed over a hopper 1 on an endless conveyor belt 5 moving in the direction of an arrow 3, which conveys the straw between two pre-press rolls 7, 9 of a pre-press roll assembly, generally designated 11, one above the other with a horizontal axis.
  • the pre-pressing rollers 7, 9 provided on their circumference with gripping teeth, strips or the like are driven in opposite directions to one another.
  • the upper pre-press roller 9 is, for example, guided in a vertically movable manner on arms, not shown, and is biased by springs or weights against the pre-press roller 7.
  • a strip roller 13 is arranged above the conveyor belt 5, axially parallel, in the same direction is driven to the pre-press roller 9 and ensures a further pre-compression of the straw introduced by the conveyor belt 5 between the pre-press rollers 7, 9.
  • the slat roller 13 can also be driven in the opposite rotating manner, in which case it then serves as a combing roller and ensures an even straw flow on the conveyor belt 5.
  • a screw pre-compressor 15 On the outlet side of the pre-press roll mill 11 there is a screw pre-compressor 15 with a compressor screw 19 arranged in a screw housing 17, axially parallel to the pre-press roll mill 11.
  • the screw pre-compactor 15 deflects the pre-pressed straw transported in the direction of arrow 3 in the axial direction of the compacting screw 19 and ensures further compacting of the straw.
  • the compressor screw 19 has an essentially cylindrical screw core 21 and an at least single-start screw helix 23, which tapers conically at its discharge end 25.
  • a motor 26 drives the screw pre-compressor 15, the pre-press roll mill 11, the strip roll 13 and optionally the conveyor belt 5.
  • the briquetting takes place in a conical screw compressor 27, the conical screw 29 of which is arranged with the screw axis 31 extending at right angles to the axis of the precompressing screw 19 in a conical compressor space 33 of a screw housing 35 firmly connected to the screw housing 17.
  • the conical screw 29, which is mounted on the screw housing 35 or a machine base via bearings 37, is driven by a drive motor, not shown, via a belt drive 39.
  • the conical compression chamber 33 opens at an axial distance from the free end of the cone screw 29 in an outlet opening 41, which, as will be explained in more detail below, is followed by a degassing ring 43 and a press die 45 with a hydraulically controllable outlet cross section.
  • the conical screw compactor 27 picks up the pre-compacted straw directly from the screw precompressor 15, the compacting screw 19 of which engages for this purpose with its end 25 in the region of the larger-diameter end of the conical screw 29 in a conical inlet opening 47 of the screw housing 35.
  • the conveying direction of the conical screw compressor 27 is horizontal and opposite to the conveying direction 3 of the conveyor belt 5. This results in an essentially U-shaped processing path, the components of the straw briquetting device being able to be arranged in a comparatively narrow space.
  • the conical screw 29 of the conical screw compressor 27 has a truncated cone-shaped screw core 49, from which a single or multiple-flight screw helix 51 with a truncated cone-shaped outer contour protrudes radially.
  • the conical compression space 33 is delimited by an inner conical surface 55 provided with radially protruding strips or ribs 53, which extends in the conveying direction of the conical screw 29 over its tapered end to the outlet opening 41 and is also provided with ribs 53 in this area.
  • the ribs 53 enclose the conical screw 29 in the form of a single or multi-start helix, the winding direction of which is opposite to the winding direction of the worm helix 51 and can be limited or formed by grooves which are incorporated in the worm housing 35.
  • the conical screw 29 conveys the pre-compacted straw supplied via the inlet opening 47 to the outlet opening, where it is jammed by the subsequent press die 45 and compressed under high pressure.
  • the compacting effect increases the temperature of the straw cake to such an extent that it bakes the straw cake into a briquette material that is compact and can be subjected to mechanical stress after the subsequent cooling. Since the compacted straw is not only driven by the conical screw 29 in the conveying direction, but is also at least partially rotated about the screw axis 31, the helically arranged ribs 53 support the conveying effect, since they screw the rotating straw in the conveying direction due to the opposite sense of the helix 51 .
  • the ribs 53 in the region of the outlet opening 41 support the passage of the compacted straw into the essentially cylindrical outlet channel 61 formed by an opening 57 of the degassing ring 43 and a die tube 59 of the press die 45.
  • the ribs 53 thus prevent the outlet opening 41 from being blocked unintentionally.
  • the heating of the compacted straw in the compressor chamber 33 is so strong that water vapor can form in particular in the area of the outlet opening 41 due to the drying process, which can lead to overpressure damage to the device, but in particular the compressed straw contained in the matrix tube 59 explosively from the compression tube 59 can drive out.
  • a plurality of degassing slots 63 distributed in the circumferential direction are provided in the degassing ring 43 adjoining the outlet opening 41.
  • the degassing slots 63 are designed as capillary slots with a slot width of the order of 1/10 mm and extend over the whole te length of the degassing ring 43.
  • the degassing slots 63 which open radially on the inside to the opening 57, open into radially overlying wider discharge channels 65, which wedge-shaped widen towards the conical screw compressor 27 and open at the end face of the degassing ring 43 into an annular channel 67 which is open to the environment.
  • the degassing slots 63 and the discharge channels 65 can be incorporated into the degassing ring 43, for example, by means of electrical erosion processes.
  • the degassing ring 43 which is designed as a separate component for easier manufacture, is seated in a chamber 69, open towards the screw housing 35, of a foot part 71 of the pressing die 45 holding the die tube 59 on the screw housing 35.
  • the die tube 59 has an outer jacket 73 which widens conically towards the conical screw compressor 27 and is divided into a plurality, here eight, radially resilient tongues 77 by a plurality of circumferentially arranged axial slots 75.
  • the outer cone of the die tube 59 is surrounded by two clamping rings 79, 81 which are connected by adjustable spacer bolts 83 to form a unit which can be moved along the die tube 59.
  • the clamping ring 79 carries a radially projecting ring flange 85 which is guided on several, here three, circumferentially offset guide rods 87 projecting from the foot part 71.
  • plate spring assemblies 89 are guided on guide rods 87, which are supported between the ring flange 85 on the one hand and screw heads 91 of the guide rods 87 on the other hand.
  • the conical surface 73 of the die tube 59 and the clamping rings 79, 81 form a self-locking for the radial pressure in the die tube 59 Wedge gear, the plate spring assemblies 89 pretensioning the clamping rings 79, 81 in the closing direction of the die tube 59.
  • the translation effect of the wedge gear is sufficient to be able to close the die tube 59 against the pressure of the compacted straw.
  • the straw heated due to the pressing action by the conical screw compressor 27 cools during the pushing out through the outlet channel 61 to a briquette strand, which is cut into pieces at the outlet of the pressing die 45 by suitable tools, for example a saw or the like.
  • the length of the die tube 59 can be shortened if the individual tongues 77 are provided with axially extending cooling water channels 97.
  • cooling water channels 99 can be provided on the outer circumference of the degassing ring 43. Inlet and outlet lines to the cooling water channels 97, 99 are not shown for the sake of simplicity.
  • FIG. 6 shows a variant of a device for briquetting straw, which differs from the device of FIGS. 1 to 5 essentially only in the type of control of the outlet pressure of the conical screw compressor. Parts having the same effect are designated in FIG. 1 with the reference numbers of FIGS. 1 to 5 and provided with the letter a to distinguish them. To explain the structure and function of these parts, reference is made to the description of FIGS. 1 to 5.

Because of this relative displacement, the outlet cross section of the die 45a is increased on the one hand and the screw housing 35a is removed from the conical screw 29a on the other hand. This reduces the jamming effect of the press die 45a on the one hand, and on the other hand there is an immediate reduction in pressure in the compressor space 33a.

  • the number of matrix tubes 129 located in the direction of rotation 145 between the filling position and the ejection position should therefore be as large as possible, compared to the remaining matrix tubes or those remaining in the opposite direction between these two positions.
  • the die tubes 129 are arranged at a distance from one another in the circumferential direction and between them delimit radial cooling air openings 147 through which a fan 149 arranged coaxially with the axis of rotation 125 conveys cooling air from radially inside to radially outside.
  • the turret press die 121 explained above can, after it manages with comparatively short die tubes 129, also be used without the degassing ring 43b explained above.
  • the turret 123 then connects essentially directly to the outlet opening 41b of the conical screw compressor 27b.
