Detailed Description
In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.
The term "plurality" as used herein refers to a plurality, typically two or more, of indefinite quantities; and when "a number" is used to denote the number of a certain number of components, the number of components is not necessarily related to each other.
The terms "first," "second," and the like herein are merely used for convenience in describing two or more structures or components having the same or similar structure, and do not denote any particular limitation of the order.
As shown in fig. 1 to 3, the present invention provides a compartment of a dryer, comprising a shoveling plate structure and a tubular compartment body 11, the shoveling plate structure comprising: the first shoveling plate group 12 comprises a plurality of first shoveling plates 121, wherein the plurality of first shoveling plates 121 are arranged on the inner wall of the bin body 11 at intervals along the circumferential direction so as to form a circle, and the inner wall of the bin body 11 is provided with a plurality of circles of first shoveling plates 121 at intervals along the axial direction; the second shoveling plate set 13 is fixed in the bin body 11 through a bracket 14, a first annular channel M is formed between the second shoveling plate set 13 and the first shoveling plate set 12, at least one second annular channel N is formed in the second shoveling plate set 13, and materials to be dried (in the field of particle board production, the materials to be dried can be wet shavings) can at least be displaced in the first annular channel M and the second annular channel N.
By adopting the scheme, the wet wood shavings can axially displace in the bin body 11 and also can circumferentially displace in the first annular channel M and the second annular channel N, and the travel of the wet wood shavings can be increased, which is equivalent to prolonging the drying time of the wet wood shavings in the bin body 11 and is beneficial to ensuring the drying effect of the wet wood shavings; moreover, the movement space of the wet wood shavings is increased, so that the accumulation and blockage of the wet wood shavings in the bin body 11 and the blockage caused by the accumulation and blockage can be avoided to a large extent, and the smooth movement of the wet wood shavings in the bin body 11 can be ensured.
It should be noted that, the cylinder of the dryer has a split structure and an integral structure, and the sub-bin provided by the invention is mainly set for the cylinder with the split structure, and when in specific operation, a plurality of sections of sub-bins provided by the invention can be adopted or combined with the sub-bins in the prior art, so as to finally form the complete cylinder of the dryer.
Specifically, as shown in fig. 4 to 6, along the axial direction of the bin body 11, a circle of the first shoveling plates 121 at the downstream can rotate by a first set angle in the same circumferential direction (anticlockwise or clockwise) relative to a circle of the first shoveling plates 121 at the upstream; the direction of the downstream turn of the first shoe 121 with respect to the upstream turn of the first shoe 121 is opposite to the direction of the rotation of the housing 11.
So, each first shoveling plate 121 can form a spiral structure which extends along the axial direction on the inner wall of the bin body 11 and is opposite to the direction of the bin body 11, when the bin body 11 rotates, the wet wood shavings can move downstream under the driving force of the spiral structure, meanwhile, under the driving of the spiral structure, the movement track of the wet wood shavings in the bin body 11 can also approach the spiral shape, the travel of the wet wood shavings in the bin body 11 can be prolonged to a greater extent, and the drying effect of the wet wood shavings can be further effectively ensured.
Here, the embodiment of the present invention is not limited to the specific value of the first setting angle, and in practical application, a person skilled in the art may set parameters such as the number of the first shovels 121 in each turn; in a specific embodiment, the first shoveling plate 121 of each turn may be set to 24 pieces, and the first setting angle may be 2-4 degrees, and may be specifically set to 3 degrees.
The first plate 121 may include a root plate portion 121a and a head portion 121b, one end of the root plate portion 121a may be attached to the inner wall of the housing 11, and the other end may be attached to the head portion 121b. When the bin body 11 rotates, wet shavings at the bottom of the bin body 11 can be lifted by the shoveling part 121b and turned over to the top of the bin body 11, then the wet shavings are scattered in a curtain shape from the top, and the wet shavings can be in a sufficient dispersion state, so that the wet shavings can be fully contacted with mixed hot air entering the bin body 11, and the rapid evaporation of moisture is promoted.
The root plate 121a may be a straight plate, the width direction of the root plate may be in the same direction as the axial direction of the bin 11, and the length direction of the root plate may be in the same direction as the radial direction of the bin 11, that is, the weld seam formed by the root plate 121a and the inner wall of the bin 11 may extend in the axial direction, and meanwhile, the root plate 121a may be perpendicular to the wall of the bin 11, so that the welding angle may be easily controlled, the welding operation may be simplified, and reliable welding between the root plate 121a and the wall may be ensured. Of course, the root plate 121a may be an arc plate, or the root plate 121a may have a certain angle with the radial direction of the bin 11, which is an option in practical implementation.
Here, the embodiment of the present invention is not limited to the specific shape of the header 121b, and may be a uniform shape or may have several shapes, so long as the header 121b is capable of lifting up the wet shavings and driving the wet shavings to turn over in the bin 11 when the bin 11 rotates.
In the embodiment of the drawings, the first turn of the first header 121 may include three types of header portions 121b, and the first header 121 having the three types of header portions 121b may be arranged in a set order in the circumferential direction.
First, as shown in fig. 7 and 8, the header 121b of the first sheet may be a bent sheet, and includes a first plate portion 121b-1 and a second plate portion 121b-2, one end of the first plate portion 121b-1 may be connected to the root plate portion 121a, the other end may be connected to the second plate portion 121b-2, and a first angle α may be formed between the first plate portion 121b-1 and the second plate portion 121b-2, where the first angle α enables the header 121b itself of such a shape to lift wet shavings; the first plate 121b-1 and the root plate 121a may form a second angle β therebetween, and 90 ° < β <180 °, the first angle α and the second angle β may be respectively located at two sides of the first plate 121b-1, in other words, if the spoon is used to match the first type of first shoveling plate, the spoon head (i.e., the shoveling head 121 b) and the spoon handle (i.e., the root plate 121 a) may be substantially flush, so that when the root plate 121a is substantially in a horizontal position and the shoveling head 121b is upward, more wet shavings may be lifted, and when other positions, the wet shavings lifted in the shoveling head 121b may gradually disperse and fall off in a curtain shape in the first annular channel M; the second plate portion 121b-2 may be a widened plate, and specifically, the width of the second plate portion 121b-2 may be gradually narrowed from upstream to downstream so as to facilitate the wet wood shavings to gradually separate from the shoveling plate under the effect of the mixed hot air.
Next, as shown in fig. 9 and 10, the header 121b of the second first header may be a straight plate and disposed at an angle with respect to the root plate 121a, where the angle makes the header 121b cooperate with the root plate 121a to lift the wet wood shavings, so as to drive the wet wood shavings to turn over from the bottom to the top of the bin 11, and the header 121b may be a widened plate. Compared with the first shoveling plate of the first type, the shoveling plate 121 of the first type can well shovel the wet shavings in the horizontal position with the shoveling head 121b facing upwards and in the vertical position, namely, the shoveling capability of the shoveling plate on the wet shavings is stronger, and the turning of the wet shavings in the bin 11 is facilitated.
Again, as shown in fig. 11 and 12, the shape of the shoveling head 121b of the third first shoveling plate is similar to that of the first shoveling plate, and may also include a first plate portion 121b-1 and a second plate portion 121b-2, a first included angle α may be formed between the first plate portion 121b-1 and the second plate portion 121b-2, a second included angle β may be formed between the first plate portion 121b-1 and the root plate portion 121a, and 90 ° < β <180 °; the difference from the first type of first shoveling plate is that the first included angle α and the second included angle β are both located on the same side of the first plate portion 121b-1, and if the spoon is still used to compare with the third type of first shoveling plate, the spoon head (i.e. the shoveling head portion 121 b) is relatively closer to the spoon handle (i.e. the root plate portion 121 a), so that the third type of parting shoveling plate of the pattern can be used to lift wet shavings in the horizontal position, the vertical position and the process that the bin 11 rotates from top to bottom, and compared with the first type of first shoveling plate 121 and the second type of first shoveling plate 121, the capability of the third type of parting shoveling plate of the pattern to lift wet shavings is stronger.
For the three first shoveling plates, the first type has the worst shoveling capability for the wet shavings, the third type has the strongest shoveling capability for the wet shavings, and the second type has moderate shoveling capability for the wet shavings, when the second type first shoveling plates are arranged along the circumferential direction, the second type first shoveling plates can be firstly arranged at equal intervals along the circumferential direction for one circle, then the first type first shoveling plates and the third type first shoveling plates are sequentially arranged between two adjacent second type first shoveling plates, so that one first type first shoveling plate or one third type first shoveling plate, one second type first shoveling plate between the first type first shoveling plate and the third type first shoveling plate are necessarily arranged between the two second type first shoveling plates, namely, the arrangement mode shown in fig. 4-6 is adopted to balance the shoveling capability of each shoveling plate for the wet shavings along the circumferential direction.
Referring to fig. 4, after the three first shoveling plates 121 are arranged in the sequence (i.e., the set sequence), each first shoveling plate 121 can basically lift up the wet shavings and drive the wet shavings to turn over from bottom to top in a quarter circle segment at the right lower part of the bin 11; in the quarter arc section at the right upper part of the bin body 11, the wet shavings lifted by the first shoveling plate start to gradually fall off and spread in a curtain shape; in the quarter arc section at the left upper part of the bin body 11, the wet shavings lifted by the second and third first shoveling plates also start to gradually fall off and spread in a curtain shape; in the quarter arc section at the left lower part of the bin body 11, each shoveling plate can gradually start to lift the wet shavings at the bottom of the bin body 11. So set up, the left half of storehouse body 11, right half all can have the wet wood shavings to be the curtain and spread out, can make full use of the interior space of storehouse body 11, accelerate the drying of wet wood shavings.
It should be understood that the above description is only one specific embodiment in which the three first shovels 121 are arranged in the set order, and it is not intended to limit the scope of the dryer provided by the present invention, and the set order in which the three first shovels 121 are arranged may be changed in implementation, for example, the three first shovels may be arranged in the circumferential order; even if the types of the first shovels 121 are changed, more or fewer types of the first shovels 121 may exist, and the first shovels of the types may be arranged in a new setting order.
As further shown in fig. 13, and referring to fig. 2, the second shoe group 13 may include an annular portion 131, where the annular portion 131 may include two annular beams 131a disposed opposite to each other in the axial direction and a plurality of connection beams 131b connecting the two annular beams 131a, and each of the connection beams 131b may be provided with a plurality of second shoes 132 at intervals in the axial direction.
The number of the annular portions 131 may be one or a plurality. When the number of the wet wood shavings is one, a first annular channel M can be formed between the annular part 131 and the first shoveling plate group 12, a circular channel (not shown in the figure) can be formed inside the annular part 131, and the wet wood shavings can also pass through the circular channel; when there are a plurality of annular portions 131, a first annular channel M may be formed between the outermost annular portion 131 and the first shoveling plate set 12, a second annular channel N may be formed between two radially adjacent annular portions 131, and a circular channel may be formed in the innermost annular portion 131.
Further, a central portion 133 may be further included, the central portion 133 may include two central plates 133a disposed opposite to each other and a central beam 133b connecting the two central plates 133a, and the central beam 133b may be provided with a plurality of second copy plates 132 at intervals in an axial direction. The aforementioned annular portion 131 may be sleeved on the central portion 133, and a second annular channel N may be formed between the annular portion 131 and the central portion 133, in which case there will be no separate circular channel.
The bracket 14 may be a tripod, which may include three legs 141, two ends of each leg 141 may be respectively connected to the central plate 133a and the inner wall of the bin 11, and each leg 141 may be fixed to the ring beam 131a to fix the second shoveling plate group 13 in each sub-cylinder; at the same time, the ring beam 131a fixed to each leg 141 corresponds to the reinforcing beam of the bracket 14, and the structural strength of the entire bracket 14 can be improved. It will be appreciated that the number of legs 141 of the stand 14 is not limited to three, but may be four, five or even more, and may be set as desired by those skilled in the art in practical applications.
The inner wall of the bin body 11 can be provided with three hanging lugs 142 at intervals along the circumferential direction, each supporting leg 141 can comprise a first sub-beam 141a, a second sub-beam 141b and a third sub-beam 141c which are sequentially hinged, the first sub-beam 141a can be further hinged with the corresponding hanging lug 142, the second sub-beam 141b can be provided with a through hole 141b-1, the annular beam 131a can be arranged through the through hole 141b-1, the annular beam 131a and the second sub-beam 141b can be fixedly connected, and the third sub-beam 141c can be further hinged with the central plate 133 a.
In this way, by adjusting the included angles among the first beam 141a, the second beam 141b and the third beam 141c, the distance between the center plate 133a and the cylinder wall of the dryer with different specifications can be adapted, so that the bracket 14 can have wider applicability; and by adopting the structure, the machining precision requirement of each beam of the supporting leg 141 can be reduced, even if a certain deviation exists between the machining size and the design value of each beam, the machining difficulty of the supporting leg 141 can be greatly reduced by adjusting the included angle of each beam to adapt.
It should be noted that, in the above-mentioned scheme, the leg 141 adopts a three-section beam structure, in fact, it may also adopt more sections of beams, which is mainly related to the number of the annular portions 131, and if the number of the annular portions 131 is plural, the number of the sections included in the leg 141 may also be increased; for example, if the number of the ring-shaped portions 131 is two, the leg 141 may include four segments, and the ring-shaped beam 131a of each ring-shaped portion 131 may be fixed to one segment.
As shown in fig. 14, the ring beam 131a may be in a split structure, which includes a plurality of arc-shaped sub beams 131a-1, so that the ring beam 131a can conveniently pass through the through holes 141b-1 of the second sub beam 141 b; in practice, adjacent ends of two adjacent arc-shaped sub beams 131a-1 may be inserted into the via holes 141b-1 of the corresponding second sub beam 141b, and fixed to the second sub beam 141b by welding. By adopting the scheme, the breaking position of the two adjacent arc-shaped sub beams 131a-1 can be hidden in the through hole 141b-1, and the circumferential structure of the annular beam 131a is kept complete by welding with the second sub beam 141b, so that the structural stability of the whole annular portion 131 can be ensured, and meanwhile, the convenience of connecting the annular beam 131a with the bracket 14 can be considered.
Here, the embodiment of the present invention is not limited to the number of the arc-shaped sub-beams 131a-1, and in a preferred embodiment, the number of the arc-shaped sub-beams 131a-1 may be the same as the number of the legs 141, so that the ends of the arc-shaped sub-beams 131a-1 can be hidden in the through holes 141b-1 of the corresponding second sub-beams 141b, and the occurrence of unnecessary welds is avoided. In other words, for the tripod having three legs 141 described above, the embodiment of the present invention preferably employs a three-section arc-shaped sub-beam 131 a-1.
As shown in fig. 15 and 16, in a specific embodiment, the first and third sub-beams 141a and 141c may each be a welded part, which may include a base plate 141a-1, two welding plates 141a-2 may be welded on the upper and lower surfaces of the two ends of the base plate 141a-1, a connection gap may be formed between the two welding plates 141a-2 located at the same end, and the two ends of the second sub-beam 141b, the hanger 142 and the center plate 133a may be inserted into the connection gap, and then, by matching with a connector in the form of a pin, the hinge relationship between the first sub-beam 141a and the hanger 142, between the second sub-beam 141b and the third sub-beam 141c and the second sub-beam 141b and between the center plate 133a may be realized.
In addition to the above, the above-described connection gaps may be provided in the lugs 142, the second beam 141b, and the center plate 133a, and thus the hinge between the beams of the leg 141 and between the leg 141 and the lugs 142 and the center plate 133a may be realized.
As shown in fig. 17, each connection beam 131b may be provided with a plurality of circles of second shoveling plates 132, each circle of second shoveling plates 132 may be disposed at intervals along the axial direction of the connection beam 131b, and each circle of second shoveling plates 132 may be uniformly distributed along the circumferential direction, so that the second shoveling plates 132 may be disposed at different positions in the circumferential direction and the axial direction of the connection beam 131b to act on wet shavings.
It will be appreciated that the number of the second shoveling plates 132 mounted on the connection beam 131b is not too large, and the second shoveling plates 132 are too large, so that the mounting of the second shoveling plates 132 is difficult, and the number of the second shoveling plates 132 is not too small, and the too small second shoveling plates 132 cannot perform the function of well shoveling and turning the wet shavings.
In order to achieve both convenience in installation and lifting and turning effects on wet shavings, in the embodiment of the present invention, a circle of second shoveling plates 132 installed downstream of the connection beam 131b may be rotated by a second set angle in the same direction (clockwise or counterclockwise) in the circumferential direction relative to an adjacent circle of second shoveling plates 132 installed upstream, so that even if the number of second shoveling plates 132 in a single circle is small, a large number of second shoveling plates 132 may be still present in the circumferential direction for the entire connection beam 131 b.
Similarly, as shown in fig. 20, the center beam 133b may be provided with a plurality of circles of the second shoveling plates 132, the circles of the second shoveling plates 132 may be disposed at intervals along the axial direction of the center beam 133b, the second shoveling plates 132 in each circle may be uniformly distributed along the circumferential direction, and a circle of the second shoveling plates 132 disposed downstream of the center beam 133b may be disposed at a third set offset angle with respect to an adjacent circle of the second shoveling plates 132 disposed upstream of the center beam 133 b.
Here, the embodiment of the present invention is not limited to a specific number of the second handsheets 132 and specific values of the second setting angle and the third setting angle, which are installed to the connection beam 131b and the center beam 133b, and may be set by those skilled in the art according to actual needs when the embodiment is implemented.
Specifically, as shown in fig. 18 and 19, the number of the second shoveling plates 132 in one turn on the connection beam 131b may be four, and two adjacent turns may be installed in a staggered manner by rotating 90 degrees in the circumferential direction, and at this time, the connection beam 131b has 8 second shoveling plates 132 in the circumferential direction; as shown in fig. 21 and 22, the number of the second shoveling plates 132 in one turn on the center beam 133b may be six, and two adjacent turns may be installed in a staggered manner by 30 degrees in the circumferential direction, and at this time, the center beam 133b corresponds to the presence of 12 second shoveling plates 132 in the circumferential direction.
The direction of the offset mounting of the second lug 132 on the downstream side of the connection beam 131b and the center beam 133b and the direction of the offset mounting of the second lug 132 on the upstream side thereof are opposite to the direction of the bin 11, that is, spiral structures opposite to the direction of the bin 11 may be formed on the annular portion 131 and the center portion 133, and the stroke of the wet wood chip displaced along with the annular portion 131 and the center portion 133 may be extended.
It should be appreciated that for a dryer cartridge having a segmented structure, it may include multiple segments of bins, wherein the bins at both ends are end portion bins, one of the two end portion bins is a feed bin and the other is a discharge bin, the feed bin is provided with a feed inlet 112a-1, and the discharge bin is provided with a discharge outlet.
When the sub-tank provided by the present invention is used as a feeding sub-tank, as shown in fig. 23, the feeding sub-tank 112 may include a front section 112a and a rear section 112b, the front section 112a is a front portion of the feeding sub-tank 112, which is provided with the above-mentioned feeding port 112a-1, and the rear section 112b is a rear portion of the feeding sub-tank 112, in which the second sheet group 13 is provided, that is, the front portion of the feeding sub-tank 112 may not be provided with the second sheet group 13. In this way, a larger space can exist in the front part of the feeding barrel 112, so that the smoothness of feeding of the wet shavings can be ensured to a larger extent, and the wet shavings entering the rotary drum 11 can quickly exchange heat and moisture with the mixed hot air.
The second shoe group 13 located in the rear section 112b may also include a center portion 133 and an annular portion 131. As shown in fig. 24 and 25, in order to reduce the feeding resistance to a greater extent, only one circle of second shoveling plates 132 may be disposed on each connection beam 131b of the annular portion 131 in the rear section 112b, and the circle of second shoveling plates 132 may be located at the end of the connection beam 131b away from the feeding port 112a-1, so that more space may be left in the feeding split cylinder 112b to ensure the smoothness of feeding to the greatest extent.
The specific shape of each second shoe 132 provided in the annular portion 131 and each second shoe 132 provided in the center portion 133 may be the same or different, and may be specifically set according to actual needs. In the embodiment of the drawings, the second shoveling plate 132 provided in the annular portion 131 may be the aforementioned second type first shoveling plate, and the second shoveling plate 132 provided in the center portion 133 may be the aforementioned third type first shoveling plate, and the second shoveling plate 132 provided in the annular portion 131 is smaller in size than the second shoveling plate 132 provided in the center portion 133 due to space limitation.
In the above embodiments, the first and second sheet groups 12 and 13 may be distributed in the drum 11 as shown in fig. 3 in the examples of the present invention. Fig. 3 shows the structures of the first and second shoe groups 12 and 13 by taking, as an example, a case where only one annular portion 131 exists in the second shoe group 13 and a central portion 133 exists.
In the mounting, the mounting direction of each second shoe 132 of the second shoe group 13 may be opposite to each first shoe 121 of the first shoe group 12, and the mounting direction here mainly means the orientation of the shoe portion 121b. With the view of fig. 3 as a view, the header 121b of each first shoveling plate 121 faces counterclockwise, and the header 121b of each second shoveling plate 132 faces clockwise, so that, at the right half of the first annular channel M, the wet shavings from each second shoveling plate 132 of the annular portion 131 gradually fall off and are scattered in a curtain shape, while each first shoveling plate 121 can alternately lift, turn over the wet shavings from the annular portion 131 and from the bottom of the bin 11, and at the left half of the first annular channel M, the wet shavings from each first shoveling plate 121 gradually fall off and are scattered in a curtain shape, while each second shoveling plate 132 of the annular portion 131 can lift and turn over the wet shavings from the first shoveling plate set 12 and from the bottom of the bin 11, so that the wet shavings in the first annular channel M can be alternately lifted, turned over and scattered by the first shovelling plate set 12 and the second shoveling plate set 13, thereby facilitating the rapid drying of the wet shavings in the first annular channel M; similarly, in the right half of the second annular channel N, the wet shavings lifted by the second shoveling plates 132 of the central portion 133 will gradually fall off and spread in a curtain shape, while the second shoveling plates 132 of the annular portion 131 can lift and turn over the wet shavings lifted by the second shoveling plates 132 of the annular portion 131 in the left half of the second annular channel N, while the second shoveling plates 132 of the central portion 133 can lift and turn over the wet shavings lifted by the annular portion 131, so that the wet shavings in the second annular channel N can alternately lift, turn over and spread between the inner and outer rings of the second shoveling plates 132, which is more beneficial to drying the wet shavings in the second annular channel N, and meanwhile, the wet shavings can be prevented from gathering at the bottom and center of the bin 11. The description herein mainly refers to the scheme of one annular portion 131 and one central portion 133 from the perspective of fig. 3, and regarding the scheme of coexistence of a plurality of annular portions 131, a plurality of annular portions 131 and a central portion 133, the embodiments of the present invention are similar to the above in effect and will not be repeated.
The above description of the mounting direction of each first shoveling plate 121 of the first shoveling plate set 12 and each second shoveling plate 132 of the second shoveling plate set 13 is only a preferred embodiment of the present invention, and it is not intended to limit the implementation range of the compartment of the dryer provided by the present invention, and the specific arrangement modes of the shoveling plates may be rearranged in consideration of the actual situation such as the difficulty of mounting.
It should be emphasized that while the present invention provides a compartment for a dryer that is designed to initially enhance the drying effect of wet strands in the field of oriented strand board production, this is not intended to be limiting of the range of applications for the compartment, and indeed the compartment may be used in other similar fields than the field of oriented strand board production.
The foregoing is merely a preferred embodiment of the present invention and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present invention, which are intended to be comprehended within the scope of the present invention.
