Description

Technical Field

[0001] The present invention belongs to the field of drying technology, and specifically relates to drying solid materials, and in particular to drying equipment and a drying process for producing bio-based materials. Background Art

[0002] Bio-based materials refer to a new type of material made from renewable biomass through biological, chemical, and physical means. After collection, bio-based materials need to be dehumidified and dried to prevent rapid decay and degradation, ensuring their reuse.

[0003] In related technologies, drying is typically performed using a hot air blower. However, bio-based materials (such as starch-based and cellulose-based materials) are inherently highly hygroscopic, causing the surface of the bio-based materials to soften and form a sticky layer, which easily clumps after drying. In related technologies, bio-based materials (such as starch-based and cellulose-based materials) are dispersed through stirring to prevent surface sticking caused by residual moisture. However, the rotation of the stirring paddle can cause the bio-based materials (such as cellulose fibers) to break, reducing mechanical properties.

[0004] Therefore, how to prevent bio-based materials from agglomerating during the drying process is a technical problem that urgently needs to be solved in this field.

[0005] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present application concept, and therefore, the above description is not considered to constitute information of related technology.

[0062] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them.

Instead, the use of the terms "example," "exemplary," and the like is intended to present concepts in a concrete manner.

[0067] After research, it was found that in the related art, drying is usually carried out by heating with a hot air blower, but the bio-based materials (such as starch-based and cellulose-based materials) themselves have strong hygroscopicity, which causes the surface of the bio-based materials to soften and form a sticky layer, which is easy to agglomerate after drying. Existing drying equipment cannot prevent the bio-based materials from agglomerating during the drying process. In the related art, bio-based materials (such as starch-based and cellulose-based materials) can be dispersed by stirring to prevent surface stickiness caused by residual moisture. However, the rotation of the stirring paddle will cause the bio-based materials (such as cellulose fibers) to break and reduce the mechanical properties. Therefore, the traditional stirring method is not suitable for the bio-based materials (such as starch-based and cellulose-based materials) of this embodiment.

[0068] Therefore, how to prevent bio-based materials from agglomerating during the drying process is a technical problem that urgently needs to be solved in this field.

[0069] The defects in the above solutions and the causes of their occurrence are the results obtained by the inventors after practice and careful research. Therefore, the process of discovering the above problems and the solutions proposed by the present disclosure in this article should be the contributions made by the inventors to the present disclosure during the disclosure process.

[0070] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0071] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0072] like Figures 1 to 8 As shown, at least one embodiment provides a drying device for bio-based material production, comprising: a drying box 1, the bottom of which is provided with a drive motor 2; the drive motor 2 is a low-speed motor, wherein the rotation speed of the rotating shaft 20 is 20-30 revolutions per minute. The drying box 1 is rectangular and placed upright; a hot air blower 11 is provided on one side of the drying box 1, and the hot air blower 11 is connected to the drying box 1 and is suitable for delivering hot air into the drying box 1. Preferably, when using cellulose-based materials, the hot air delivered by the hot air blower 11 in the drying box 1 has a temperature of 55-80°C.

[0073] Reference Attachment Figure 2 , a partition 10 is horizontally arranged inside the drying box 1; a transmission sleeve 3 is rotatably arranged on the partition 10 and is sleeved on the outer wall of the rotating shaft 20 of the drive motor 2; the transmission sleeve 3 adopts a detachable structure. When the protrusion 21 abuts the sliding block 51, the transmission sleeve 3 rotates synchronously with the rotating shaft 20; when the protrusion 21 is disengaged from the sliding block 51, the rotating shaft 20 rotates relative to the transmission sleeve 3. In this state, the rotating shaft 20 rotates idly relative to the transmission sleeve 3. A protrusion 21 is radially provided on the outer wall of the rotating shaft 20; a loading tray 4 is sleeved on the outer wall of the transmission sleeve 3; the loading tray 4 is parallel to the partition 10, and a fixed cylinder 40 is axially provided, the fixed cylinder 40 is sleeved on the outer wall of the transmission sleeve 3, and a gap is provided between the inner wall of the fixed cylinder 40 and the outer wall of the outer friction cylinder 32.

[0074] Reference Attachment Figure 4The linkage structure 5 is disposed within the transmission sleeve 3. The linkage structure 5 includes a sliding block 51 radially slidably disposed on the inner wall of the inner positioning cylinder 31 and facing the rotating shaft 20. The upper end of the sliding block 51 is aligned with the upper end of the protrusion 21. The lower end of the sliding block 51 extends toward the partition 10, and its axial width is greater than the axial width of the protrusion 21. The drive motor 2 drives the rotating shaft 20 to rotate until the protrusion 21 abuts the sliding block 51. The protrusion 21 strikes the side wall of the sliding block 51, vibrating the loading tray 4. The protrusion 21 strikes the sliding block 51, vibrating the loading tray 4, thereby causing the material in the loading tray 4 to move from a static state to a rotating state, thereby achieving the effect of vibrating the material in the loading tray 4. An elastic member 52 is disposed between the side wall of the sliding block 51 and the inner wall of the outer friction cylinder 32, and is adapted to push the sliding block 51 toward the rotating shaft 20. The elastic member 52 is a compression spring.

[0075] The hot air blower 11 is adapted to deliver hot air into the drying oven 1. When the temperature within the drying oven 1 rises to a predetermined level, the outer friction cylinder 32 expands and deforms due to the heat, causing an interference fit with the inner wall of the fixed cylinder 40. When the rotating shaft 20 drives the protrusion 21 to rotate, the protrusion 21 strikes the sidewall of the sliding block 51, vibrating the carrier plate 4. The rotation of the protrusion 21 driven by the rotating shaft 20 drives the synchronous rotation of the outer friction cylinder 32, the fixed cylinder 40, and the carrier plate 4. The sliding block 51 slides away from the rotating shaft 20 until it disengages from the protrusion 21, and the rotating shaft 20 drives the protrusion 21 to rotate relative to the inner positioning cylinder 31.

[0076] Through the cooperation of the transmission sleeve 3, the loading tray 4 and the linkage structure 5, the transmission sleeve 3 expands due to heat and abuts against the inner wall of the loading tray 4, and the rotating shaft 20 rotates until the protrusion 21 abuts against the linkage structure 5, so that the loading tray 4 rotates synchronously with the rotating shaft 20; the protrusion 21 intermittently hits the sliding block 51, so that the material in the loading tray 4 slides relative to the loading tray 4, thereby shaking the material in the loading tray 4, thereby preventing the material in the loading tray 4 from sticking to each other and clumping.

[0077] Reference Attachment Figure 3 and Figure 4 The transmission sleeve 3 includes an inner positioning cylinder 31 and an outer friction cylinder 32, with a cavity 34 defined between the inner positioning cylinder 31 and the outer friction cylinder 32. A fixing ring 310 is provided at the upper end of the inner positioning cylinder 31. The outer diameter of the fixing ring 310 is no larger than that of the outer friction cylinder 32, and the upper end of the outer friction cylinder 32 is fixed to the bottom wall of the fixing ring 310. The horizontal height of the fixing cylinder 40 is less than that of the fixing ring 310.

[0078] The fixed cylinder 40 is adapted to tilt axially relative to the outer friction cylinder 32 to facilitate access to and placement of the loading tray 4. The outer friction cylinder 32 is a thermal expansion component, preferably made of silicone rubber, which has a volume expansion rate of 5%-8% at 55-80°C, effectively filling the gap between the fixed cylinder 40 and the outer friction cylinder 32. Thermal expansion and deformation of the outer friction cylinder 32 create an interference fit between the outer wall of the outer friction cylinder 32 and the inner wall of the fixed cylinder 40. Rotation of the outer friction cylinder 32 simultaneously drives the fixed cylinder 40 and the loading tray 4 to rotate.

[0079] Reference Attachment Figure 3 The outer wall of the transmission sleeve 3 is fixed with a carrier 33. The carrier 33 is located below the carrier plate 4 and has an outer diameter larger than the inner diameter of the fixed cylinder 40. The carrier 33 is suitable for supporting the carrier plate 4. At room temperature, the outer friction cylinder 32 rotates relative to the carrier plate 4. When the carrier plate 4 tilts relative to the carrier 33, the carrier plate 4 tilts relative to the horizontal plane, and the axis of the fixed cylinder 40 tilts relative to the axis of the inner positioning cylinder 31. Since the outer friction cylinder 32 is a flexible component, the inner wall of the tilted fixed cylinder 40 will squeeze the outer wall of the outer friction cylinder 32. The fixed cylinder 40 can tilt axially relative to the outer friction cylinder 32, making it easier to remove and place the carrier plate 4.

[0080] Reference Attachment Figure 5 A positioning block 53 is vertically fixed to the partition 10. The positioning block 53 extends axially along the inner positioning cylinder 31 and is lower in height than the protrusion 21. When the rotating shaft 20 drives the protrusion 21 to rotate, the positioning block 53 does not interfere with the circumferential rotation of the protrusion 21. The lower sidewall of the sliding block 51 and the upper sidewall of the positioning block 53 partially overlap in the axial direction. When the protrusion 21 abuts the sliding block 51, the rotating shaft 20 drives the protrusion 21 and the inner positioning cylinder 31 to rotate synchronously. When the inner positioning cylinder 31 and the sliding block 51 rotate until they abut against the positioning block 53 (the protrusion 21 moves to directly above the positioning block 53), the positioning block 53 is adapted to push the sliding block 51 to slide radially outward, so that the sliding block 51 disengages from the protrusion 21. The protrusion 21 passes over the sliding block 51 and continues to rotate. The drive motor 2 drives the rotating shaft 20 and the protrusion 21 to rotate relative to the inner positioning cylinder 31. After the rotating shaft 20 and the protrusion 21 rotate 360°, the protrusion 21 hits the side wall of the sliding block 51 again.

[0081] Reference Attachment Figure 5 In order to push the sliding block 51 to slide radially outward, a first inclined surface 54 is provided on the side of the positioning block 53 close to the sliding block 51; a second inclined surface 510 is provided on the side wall of the sliding block 51 to match the first inclined surface 54; wherein, when the protrusion 21 drives the sliding block 51 to rotate until it abuts against the positioning block 53, the first inclined surface 54 abuts against the second inclined surface 510, and the sliding block 51 moves outward until it disengages from the protrusion 21.

[0082] Reference Attachment Figure 3 . A plurality of air holes 41 are provided in a matrix on the carrier plate 4, and the diameter of the air holes 41 is smaller than the particle size of the material; a protective ring 42 is provided circumferentially on the outer wall of the carrier plate 4, and the axial height of the protective ring 42 is not less than the axial height of the fixed cylinder 40.

[0083] The specific working principle is as follows:

[0084] Reference Attachment Figure 6 After the loading tray 4 is placed horizontally on the carrier 33, the fixed cylinder 40 is synchronously sleeved onto the outer wall of the outer friction cylinder 32. As the temperature inside the drying oven 1 rises, the outer friction cylinder 32 expands and deforms due to the heat, forming an interference fit with the inner wall of the fixed cylinder 40, causing the loading tray 4 to rotate synchronously. The rotating shaft 20 drives the protrusion 21 to rotate synchronously until the protrusion 21 abuts the side wall of the sliding block 51. The rotating protrusion 21 strikes the side wall of the stationary sliding block 51, generating vibration. The rotating shaft 20 continues to rotate, driving the protrusion 21, sliding block 51, outer friction cylinder 32, fixed cylinder 40, and loading tray 4 to rotate synchronously. Figure 6 Here, F1 represents the rotation direction of the rotating shaft 20, and F2 represents the rotation direction of the outer friction cylinder 32. When the protrusion 21 abuts against the sliding block 51, the rotation directions of F1 and F2 are consistent.

[0085] Reference Attachment Figure 7 , the protrusion 21 drives the sliding block 51, so that the inner positioning cylinder 31 and the outer friction cylinder 32 rotate synchronously with the rotating shaft 20, until the sliding block 51 abuts against the positioning block 53 (because the horizontal height of the positioning block 53 is lower than the horizontal height of the protrusion 21, and the lower end side wall of the sliding block 51 and the upper end side wall of the positioning block 53 partially overlap in the axial direction); when the protrusion 21 drives the sliding block 51 to continue rotating, the positioning block 53 pushes the sliding block 51 to slide radially outward, ( Figure 7 F2 in the figure represents the outward sliding direction of the sliding block 51) At this time, the protrusion 21 moves to just above the positioning block 53, and the sliding block 51 is pushed by the positioning block 53 to slide outward, so that the sliding block 51 is disengaged from the protrusion 21. Figure 7 F1 in the figure indicates the rotation direction of the shaft 20. Since the protrusion 21 is disengaged from the sliding block 51, the shaft 20 only drives the protrusion 21 to rotate, while the sliding block 51, the outer friction cylinder 32, the fixed cylinder 40 and the loading plate 4 remain stationary.

[0086] Reference Attachment Figure 8 When the protrusion 21 is separated from the sliding block 51, the elastic member 52 pushes the sliding block 51 to slide back inward ( Figure 8 F2 in the figure indicates the sliding direction of the sliding block 51 to reset inwards). After the sliding block 51 is separated from the protrusion 21, the protrusion 21 passes over the sliding block 51 and continues to rotate ( Figure 8F1 in the figure represents the rotation direction of the shaft 20). At this time, the inner positioning cylinder 31 and the outer friction cylinder 32 drive the sliding block 51 to rotate relative to the positioning block 53 by inertia, until the sliding block 51 and the positioning block 53 are misaligned ( Figure 8 The middle sliding block 51 rotates from the right side of the positioning block 53 to the left side of the positioning block 53 due to inertia); the rotating shaft 20 drives the protrusion 21 to continue rotating. At this time, the inner positioning cylinder 31, the outer friction cylinder 32 and the loading plate 4 remain stationary. After the rotating shaft 20 drives the protrusion 21 to rotate one circle (i.e., rotates 360°), the protrusion 21 hits the side wall of the sliding block 51 again. The rotating protrusion 21 hits the side wall of the stationary sliding block 51, generating vibration again.

[0087] The protrusion 21 intermittently strikes the sliding block 51 to generate vibration, which is transmitted to the loading tray 4 through the transmission sleeve 3, so that the material in the loading tray 4 slides relative to the loading tray 4, thereby shaking the material in the loading tray 4, thereby preventing the material in the loading tray 4 from sticking to each other.

[0088] At least one embodiment provides a drying process for a drying device, the drying process comprising:

[0089] The material is placed in the loading tray 4, and the loading tray 4 is sleeved on the outer wall of the transmission sleeve 3; when the temperature in the drying oven 1 rises, the transmission sleeve 3 expands and deforms due to the heat, and abuts against the inner wall of the loading tray 4 with an interference fit; when the rotating shaft 20 drives the protrusion 21 to rotate, the protrusion 21 hits the side wall of the sliding block 51 to vibrate the loading tray 4; the sliding block 51 slides in a direction away from the rotating shaft 20 until it is disengaged from the protrusion 21, and the rotating shaft 20 drives the protrusion 21 to rotate relative to the inner positioning cylinder 31; when the rotating shaft 20 drives the protrusion 21 to rotate 360° and abuts against the sliding block 51 again, the protrusion 21 hits the side wall of the sliding block 51 again, vibrating the loading tray 4 again and driving the loading tray 4 to rotate synchronously.
