    专利说明:

    The invention relates to a timber thawing plant according to the preamble of patent claim 1.
    Raw wood, for example tree trunks, are often stored outdoors, which can also freeze at low temperatures. Before further processing, for example to chipboard, the frozen wood is thawed. Here it is known to promote the raw wood through a pool with warm water to thaw it.
    The disadvantage of this is that this process consumes a lot of energy, and much of the heat energy is lost unused.
    The object of the invention is therefore to provide a Holzauftauanlage of the type mentioned, with which the mentioned disadvantages can be avoided, with which the method for thawing can be done more energy efficient.
    This is achieved by the features of claim 1 according to the invention.
    This results in the advantage that the thawing of the raw wood can be carried out particularly energy efficient, in particular, a core of the raw wood can be thawed particularly reliable. By constructing the thawing channel in sections, with a pumping line between the sections conveying the effluent against a conveying direction of the pieces of raw wood, a very good heat transfer from the thawing liquid to the pieces of roughwood can be achieved, similar to a countercurrent heat exchanger, whereby a local temperature difference between the thawing liquid and the piece of roughwood can be kept low , As a result, it can further be achieved that the raw wood piece at the outlet of the thawing channel is in contact with a substantially barely cooled and therefore particularly warm thawing liquid, whereby the core of the piece of raw wood can also be thawed particularly reliably. At the entrance of the thawing channel, the defrosting liquid is already strongly cooled, whereby hardly any heat energy is lost by removing the defrosting liquid at this point.
    The invention further relates to a method for thawing frozen pieces of wood according to claim 10.
    The object of the invention is therefore also to provide a method of the type mentioned at the beginning, with which the mentioned disadvantages can be avoided, with which the method for thawing can be made more energy-efficient.
    This is achieved by the features of claim 10 according to the invention.
    The advantages of the method correspond to the advantages of Holzauftauanlage.
    The subclaims relate to further advantageous embodiments of the invention.
    It is hereby expressly referred to the wording of the claims, whereby the claims at this point are incorporated by reference into the description and are considered to be reproduced verbatim.
    The invention will be further described with reference to the accompanying drawings, in which only one preferred embodiment is shown by way of example. Showing:
    Fig. 1 shows a preferred embodiment of the Holzauftauanlage as a section inSeitenansicht;
    Fig. 2 shows a preferred embodiment of Holzauftauanlage in plan view;
    Fig. 3 shows a preferred embodiment of the timber thawing plant as a section in front view; and
    4 shows a detail from FIG. 1.
    Figures 1 to 4 show a preferred embodiment of a timber thawing installation 1 for thawing frozen pieces of roughwood, the timber thawing installation 1 having an air duct 2, the defrosting duct 2 having an inlet 3 and an outlet 4 for the pieces of raw wood, with nozzles 5 arranged on the thawing channel (2) are for introducing a Auftauflüssigkeit 6 in the thawing channel (2).
    A Holzauftauanlage 1 is a facility for thawing wood, especially wood, the wood thawing 1 is provided to receive the raw wood pieces in a frozen state and to freeze, ie to raise their temperature above the freezing point. The raw wood pieces may in particular be round wood pieces, preferably logs.
    The Holzauftauanlage 1 has a thawing channel 2, through which the Holzholzstücke can be promoted. The thawing channel 2 may in particular be designed as an elongated basin.
    Here, the thawing channel 2 has an inlet 3 and an outlet 4 for the pieces of wood, the pieces of raw wood being conveyed from the inlet 3 to the outlet 4. The conveying direction of the raw wood pieces therefore runs from the inlet 3 to the outlet 4. The conveying direction is indicated by arrows in FIGS. 1 and 4.
    The conveying of the pieces of raw wood in the thawing channel 2 can be effected in particular by means of a conveying device 15, which preferably runs through the entire air duct 2, that is to say from the inlet 3 to the outlet 4. In particular, the conveyor 15 may be a continuous conveyor, most preferably a chain conveyor.
    The thawing channel 2 may be particularly preferably formed straight, as shown for example in Figs. 1 and 2. In Figs. 1 and 2, not all sections 7, 71, 72, 73 and not all of the individual sections 7, 71, 72, 73 can be assigned and repeated characteristics are provided with a reference numeral.
    Alternatively it can be provided that the thawing channel 2 has at least one bend.
    The defrosting channel 2 is intended to receive a defrosting liquid 6. The blow-off liquid 6 may in particular be water. However, other effluents 6 such as oils or mixtures of various liquids are also possible. In operation, the defrosting liquid 6 releases its heat to the pieces of raw wood to thaw it. The level of the Auftauflüssigkeit 6 in the thawing channel 2 is in theFig. 1 and 4 indicated by a jagged line.
    The amount of the Auftauflüssigkeit 6 in the thawing channel 2 may be particularly preferably chosen such that the individual pieces of raw wood do not float.
    The introduction of the Auftauflüssigkeit 6 in the thawing channel 2 via nozzles 5. The nozzles 5 denote here an outlet opening from the pumping line eighth
    It is provided that a first section 7, 71 of the thawing channel 2 and a second section 7, 72 of the thawing channel 2 are arranged between the inlet 3 and the outlet 4 such that the outlet 4 is closer to the second section 7, 72 than to the first section 7, 71 in that at least one of the nozzles 5 is arranged in the first section 7, 71 and is connected via a pumping line 8 to at least one suction opening 9 arranged in the second section 7, 72. In other words, between the inlet 3 and the outlet 4, a first section 7, 71 of the thawing channel 2 and a second section 7, 72 of the thawing channel 2 arranged downstream of the first section 7, 71 are arranged, with at least one nozzle 5 of the first Section 7, 71 is connected via a pumping line 8 to at least one suction opening 9 of the second section 7, 72. In this case, the Auftauflüssigkeit 6 is removed from the Auftaukanal 2 through the second section 7,72abed intake 9, pumped in the pumping line 8 against the conveying direction, and introduced in the first section 7,71 wieder in the thawing channel 2.
    Furthermore, a method for thawing frozen pieces of raw wood, in particular in a timber thawing plant 1, is provided, wherein the pieces of raw wood in a thawing channel 2 at least partially filled with a discharging liquid 6 are first passed through a first section 7, 71 of the thawing channel 2 and subsequently through a second section 7, 72 of the thawing channel 2 Aftertaste 2 are conveyed, wherein the Auftauflüssigkeit 6 is pumped from the second section 7,72 via a pumping line 8 in the first section 7,71.
    This results in the advantage that the thawing of the raw wood can be carried out particularly energy efficient, in particular, a core of the raw wood can be thawed especially reliable on. By the construction of the thawing channel 2in sections 7,71,72,73, wherein a pumping line 8 between the sections 7,71,72,73 promotes the Auftauflüssigkeit 6 against a conveying direction of the raw wood pieces, similar to a Gegenstromwärmetäuscher a particularly good heat transfer from the Auftauflüssigkeit 6 can be achieved to the raw wood pieces, wherein a local temperature difference between the Auftauflüssigkeit 6 and the raw wood piece can be kept low. As a result, it can further be achieved that the raw wood piece at the outlet 4 of the thawing channel 2 is in contact with a substantially barely cooled and therefore particularly warm thawing liquid 6, whereby the core of the piece of raw wood can also be thawed particularly reliably. At the entrance 3 of the thawing channel 2, the Auftauflüssigkeit 6bereits already strongly cooled, whereby hardly any heat energy is lost by removing the Auftauflüssigkeit 6 at this point.
    In particular, the raw wood pieces can be conveyed continuously through the various sections 7, 71, 72, 73.
    Sections 7, 71, 72, 73 together form a continuous channel for the pieces of woodwood, with adjacent sections 7, 71, 72, 73 separated from each other by an imaginary plane transverse to the conveying direction.
    It can preferably be provided that the second section 7, 72 is arranged directly adjacent to the first section 7, 71. The second section 7, 7 thus follows directly the first section 7, 7, whereby a particularly uniform temperature profile is achieved.
    Alternatively, the pumping line 8 may extend over more than one section 7,71,72,73.
    In particular, provision may be made for a third section 7, 73 of the thawing channel 2 to be arranged between the second section 7, 72 of the air duct 2 and the outlet 4, and for at least one of the nozzles 5 to be arranged in the second section 7, 7 and via a pumping line 8 at least one, in the third section 7, 72 arranged, suction port 9 is connected. Here, preferably, viewed in the conveying direction, after the second section 7, 72 of the air duct 2, the third section 7, 37 of the thawing channel 2 can be arranged, wherein at least one nozzle 5 of the second section 7, 72 is connected via a pumping line 8 to at least one suction opening 9 of the third The second section 7,72 is thus a section 7,71,72,73, the nozzle 5 with the
    Suction port 9 of a - seen in the conveying direction - subsequent section 7.71.72.73 is connected, while the suction port 9 of this second section 7,72 with the nozzle 5 of a - seen in the conveying direction - ahead section 7,71,72,73 is connected. As a result, the delivery liquid 6 is conveyed against the conveying direction of the raw wood pieces. Thus, for many sections 7, 71, 72, 73, the individual sections may be considered both the first section 7, 71, the second section 7, 72, or the third section 7, 73. This is illustrated clearly in FIG. 4, where the reference numeral for the first section 7, 71, the second section 7, 7 and the third section 7, 73 is assigned once, it being understood that these assignments are also displaced in or against the conveying direction can.
    Particularly preferably, it can be provided that the thawing channel 2 has a multiplicity of essentially identical sections 7, 71, 72, 73, that at least one nozzle 5, one suction opening 9 and one pumping line 8 are arranged in each of these sections 7, 71, 72, 73 , and that the at least one nozzle 5 of each section 7, 71, 72, 73 is connected via the pumping line 8 to an intake opening 9 arranged in another section 7, 71, 72, 73 which is closer to the outlet 4. Here, the at least one nozzle 5 of each section 7.71.72.73 via the pumping line 8 with a suction port 9 of a - viewed in the conveying direction - subsequent section 7,71,72,73 be connected.
    The thawing channel 2 may therefore preferably comprise a series of substantially identically formed sections 7, 71, 72, 73 through which the raw wood pieces are conveyed. Via the pumping lines 8, the defrosting liquid 6 is pumped from section 7,71,72,73 to section 7,71,72,73 against the conveying direction, wherein the Auftauflüssigkeit 6 in each section a part of their heat to the raw wood pieces emits and thereby cools while the raw wood pieces are heated continuously.
    At the edges of the series of substantially identically formed sections 7.71.72.73 edge sections 74 may be arranged, which are incomplete in comparison to the sections 7, 71, 72, 73 in the row, since these are no longer connected to a present or following section 7, 71,72,73 are connected.
    In particular, it can be provided that one of the pumping lines 8 connects only the at least one suction opening 9 of a single section 7, 71, 72, 73 with only the at least one nozzle 5 of another section 7, 71, 72, 73. In other words, one of the pumping lines 8 connects only two sections 7, 71, 72, 73 with each other.
    The thawing channel 2 may in particular have more than 5, preferably more than 10, more preferably more than 20, sections 7, 71, 72, 73.
    The sections 7, 71, 72, 73 may be particularly preferably designed as joinable segments. Thus, the Holzauftauanlage 1 can be particularly simple to build, and the length of the thawing channel 2 can be easily adjusted.
    The individual sections 7, 71, 72, 73 can in particular have a length of between 1 and 5 m, particularly preferably between 1.5 and 2.5 m.
    In particular, the pumping line 8 may comprise a pump 16 which pumps the discharge liquid 6 through the pumping line 8. In particular, the pump 16 may be a dirty water pump.
    The pumping line 8 can in particular run outside of the thawing channel 2.
    It can preferably be provided that the nozzles 5 are arranged on an upper side 10 of the air duct 2. In particular, the nozzles 5 can be directed downwards in the operating position. As a result, the raw wood pieces are reliably doused in each section 7,71,72,73 from above with the Auftauflüssigkeit 6, whereby a particularly uniform heat transfer can take place.
    The nozzles 5 may preferably be formed as swirl nozzles.
    Each section 7, 71, 72, 73 may in particular have a multiplicity of nozzles 5.
    The nozzles 5 may be particularly preferably directed substantially transversely to the conveying direction of the raw wood pieces. It can thus be achieved that through the nozzles 5 no strong flow of the Auftauflüssigkeit 6 causes parallel to the conveying direction, which would favor an exchange of the Auftauflüssigkeit 6 between the individual sections 7,71,72,73 within the thawing channel 2.
    In particular, it can be provided that in the individual sections 7, 71, 72, 73 the defrosting liquid 6 in the thawing channel 2 is flowed substantially transversely to the conveying direction of the pieces of rough wood, and that transport of the air-discharging liquid 6 between the sections 7, 71, 72, 73 is predominantly through the pumping lines 8 takes place. That transport of the defrosting liquid 6 between the sections 7, 71, 72, 73 takes place predominantly through the pumping lines 8 means that at least half of the exchange of the defrosting liquid 6 between two adjacent sections 7, 71, 72, 73 takes place via the pumping line 8, and not as Flow in the thawing channel 2. Thereby, the replacement of the Auftauflüssigkeit 6 between two sections 7,71,72,73 can be well controlled and predetermined, and is only slightly dependent on the capacity of the pieces of wood in the thawing channel 2.
    Furthermore, it can be provided that the suction openings 9 are arranged on an underside 11 of the thawing channel 2. This allows the defrosting liquid 6 to be pumped out after it has completely passed through the individual section 7, 71, 72, 73.
    In particular, it can be provided that an equalizing tank 14 is arranged below the thawing channel 2. The equalizing tank 14 is particularly useful as a buffer for the defrosting liquid 6, so that fluctuations in the liquid level in the thawing channel 2 can be balanced by varying filling amounts of the raw wood pieces. Furthermore, the defrosting channel 2 can be emptied quickly for the case of maintenance.
    Particularly preferably, it can be anticipated that the Auftauflüssigkeit 6 is heated in a heating device to a predetermined temperature and then introduced in the region of the exit 4 of the thawing channel 2 in the thawing channel 2. In particular, the heating device may be a burner or a heat exchanger, through which the Auftauflüssigkeit 6 can be supplied to the heat energy required for the Luftausprozeß. Thereby, the heated Auftauflüssigkeit 6 is fed only in the region of the output 4, and can then be pumped by the pumping lines 8 via the individual sections 7,71,72,73 against the conveying direction.
    The heating device may in particular have a feed line which opens into the thawing channel 2 in the region of the outlet 4 of the thawing channel 2. The feed line may in particular open into a rim section 74, which is close to the outlet 4.
    Furthermore, it can be provided that the heating device removes the defrosting liquid 6 at least indirectly from the area of the inlet 3 of the defrosting channel 2 from the air duct 2. Thereby, a closed circuit for the exhaust liquid 6 can be achieved, wherein the Auftauflüssigkeit 6 is cooled in the thawing channel from the output 4 to the input 3, and then reheated by the Aufeehizeinrichtung.
    This removal of Auftauflüssigkeit 6 from the thawing channel 2 can take place via a sampling line from the area of the entrance 3 of the thawing channel 2.
    Furthermore, it can be provided that the Auftauflüssigkeit 6 emerges in the region of the Eingangs3 from the thawing channel 2 in the equalizing tank 14. The defrosting liquid 6 may then be introduced from the equalizing tank 14 into the heating device.
    Preferably, it can be provided that the Auftauflüssigkeit 6 is cleaned in front of the heating device in a cleaning device.
    In particular, it can be provided that the Auftauflüssigkeit 6 is heated in the Aufeehizeinrichtung to a predetermined temperature of 50 ° C to 99 ° C, in particular 60 ° C to 70 ° C.
    It can be provided that the Auftauflüssigkeit 6 in the region of the output 4 at a temperature of 50X to 99 ° C, in particular 60 ° C to 70 ° C, is introduced.
    Furthermore, it can be provided that the Auftauflüssigkeit 6 in the region of the Eingangs3 of the thawing channel 2 has a temperature of 0 ° C to 15 ° C, in particular 0 ° C to 7 ° C. If the Auftauflüssigkeit 6 is brought out of the thawing channel 2 with such a low temperature hardly any heat energy is lost unused.
    Particularly preferably, it can be provided that in the thawing channel 2 a conveying device 15 is arranged for a transverse transport of the pieces of raw wood in the conveying direction. It can be provided that the raw wood pieces are conveyed in the transverse transport through the thawing channel 2. As a result, a high filling density of the raw wood pieces in the thawing channel 2 can be achieved. Furthermore, it can be achieved that a flow of the Auftauflüssigkeit 6 is prevented parallel to the conveying direction by lying across the conveying direction pieces of wood in the thawing channel 2. Thereby, it can be supported that transport of the Auftauflüssigkeit 6 between the sections 7,71,72,73 takes place mainly via the pumping lines 8.
    Furthermore, it can be provided that the raw wood pieces are conveyed through the thawing channel 2 in a plurality of layers one above the other, that is to say in particular as a pile of wood.
    Particularly preferably, it can be provided that the nozzles 5, in particular in each of the sections 7, 71, 72, 73, extend over an entire width of the thawing channel 2. This is shown in FIG. 2.
    The thawing channel 2 may in particular be designed as an elongated basin. The air duct 2 may in this case have two side walls 18 which laterally delimit the space in the air duct 2. Furthermore, the thawing channel 2 may be closed at its front sides 19.
    In order to introduce the pieces of raw wood into the thawing channel 2, provision may be made for a feed device 20 for the pieces of rough wood to be arranged at the entrance 3. The feeding device 20 may in particular comprise a chute 21 and a retaining device 22. By the retainer 22, the formation of a pile of wood from the pieces of raw wood can be assisted.
    At the exit 4 of the thawing channel 2 it can be provided that the conveying device 15 is formed rising in a ramp shape in order to bring the raw wood pieces out of the air duct 2.
    The frozen raw wood pieces may often have contaminants on their surface which are frozen and fall off the pieces of woodwood during thawing and accumulate on the underside 11 of the thawing channel 2.
    Specifically, it may be provided that on the underside 11 of the thawing channel 2, a scraping device 12 and a subchannel 13 extending in a longitudinal direction of the thawing channel 2 are arranged, and that the scraping device 12 is adapted to deposit contaminants on the underside 11 of the thawing channel 2 into the lower channel 13. In particular, the scraping device 12 may comprise a plurality of conveyors, in particular chain conveyors, which convey transversely to the conveying direction of the pieces of rough wood. As a result, contaminants can be reliably supplied from the bottom 11 of the thawing passage 2 into the subchannel 13.
    The subchannel 13 may in this case be a further longitudinal channel in the air duct 2.
    In this case, an upper edge of the scraping device 12 can be arranged lower than an upper edge of the conveying device 15. As a result, the scraping device 12 reliably removes the contaminants without damaging the raw wood pieces.
    Particularly preferably, provision may be made for a contamination conveyor 23 for the contaminants to be arranged in the subchannel 13. The contaminant conveying device 23 can be designed, in particular, as a continuous conveyor, in particular as a chain conveyor.
    Particularly preferably, it may be provided that a conveying direction of the contaminant conveying device 23 from the output 4 to the inlet 3 runs. Thereby, the impurities at the entrance 3 of the thawing channel 2, where the temperature of the Auftauflüssigkeit 6 is the lowest, are discharged from the thawing channel 2.
