Description

Technical Field

[0001] The present invention belongs to the technical field of drying, specifically relates to drying solid materials, and particularly relates to a drying device and a drying process for the production of bio-based materials. Background Art

[0002] Bio-based materials refer to a new type of materials made from renewable biomass through biological, chemical, physical and other means. After the bio-based materials are collected, they need to be dehumidified and dried to prevent them from rapidly rotting and degrading, and to ensure the reuse of bio-based materials.

[0003] In the related art, drying is usually carried out by heating with a hot air blower. However, bio-based materials (such as starch-based and cellulose-based materials) themselves have strong hygroscopicity, resulting in the softening of the surface of bio-based materials to form a viscous layer, and they are prone to caking after drying. In the related art, bio-based materials (such as starch-based and cellulose-based materials) are dispersed by stirring to prevent surface adhesion caused by residual moisture. However, the rotation of the stirring paddle will cause the bio-based materials (such as cellulose fibers) to break, reducing the mechanical properties.

[0004] Therefore, how to avoid caking of bio-based materials 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 art section is only used to understand the background art of the concept of this application. Therefore, the above description is not considered to constitute information on the related art. Summary of the Invention

[0007] In a first aspect, the embodiments of the present disclosure provide a drying device for the production of bio-based materials, including: A drying box, at the bottom of which a driving motor is provided; A transmission sleeve, which is rotatably arranged on a partition plate and sleeved on the outer wall of the rotating shaft of the driving motor; A carrier plate, which is parallel to the partition plate, and a fixed cylinder is axially arranged on the carrier plate, and the fixed cylinder is sleeved on the outer wall of the transmission sleeve; The transmission sleeve includes an inner positioning cylinder and an outer friction cylinder, and there is a cavity between the inner positioning cylinder and the outer friction cylinder; The outer friction cylinder is a thermal expansion part, and there is a gap between its outer wall and the inner wall of the fixed cylinder; A linkage structure, including: A sliding block, which is radially slidably arranged on the inner wall of the inner positioning cylinder and faces the rotating shaft; An elastic member, which is arranged between the side wall of the sliding block and the inner wall of the outer friction cylinder and is used to push the sliding block towards the rotating shaft direction; When the temperature inside the drying oven rises to the preset temperature, the outer friction cylinder expands and deforms due to heat and is in interference fit with the inner wall of the fixed cylinder and abuts against it. When the rotating shaft drives the convex block to rotate, the convex block impacts the side wall of the sliding block to vibrate the loading tray. The sliding block slides away from the rotating shaft until it disengages from the convex block, and the rotating shaft drives the convex block to rotate relative to the inner positioning cylinder.

[0008] In an alternative embodiment, the convex block is radially fixed on the outer wall of the rotating shaft, and the horizontal height of the upper end is the same as the horizontal height of the upper end of the sliding block. The lower end of the sliding block extends towards the partition board, and the axial width is greater than the axial width of the convex block. Among them, when the driving motor drives the rotating shaft to rotate until the convex block abuts against the sliding block, the convex block impacts the side wall of the sliding block to vibrate the loading tray.

[0009] In an alternative embodiment, a positioning block is vertically fixed on the partition board, and the positioning block extends along the axial direction of the inner positioning cylinder. The horizontal height of the positioning block is lower than the horizontal height of the convex block. The side wall of the lower end of the sliding block and the side wall of the upper end of the positioning block partially overlap axially. Among them, when the convex block abuts against the sliding block, the rotating shaft drives the convex block to rotate synchronously with the inner positioning cylinder. When the sliding block abuts against the positioning block, the positioning block is adapted to push the sliding block to slide radially outwards so that the sliding block disengages from the convex block. The driving motor drives the rotating shaft and the convex block to rotate relative to the inner positioning cylinder.

[0010] In an alternative embodiment, a first inclined surface is provided on one side of the positioning block close to the sliding block. A second inclined surface matching the first inclined surface is provided on the side wall of the sliding block. Among them, when the convex block drives the sliding block to rotate until it abuts against the positioning block, the first inclined surface abuts against the second inclined surface, and the sliding block moves outwards until it disengages from the convex block.

[0011] In an alternative embodiment, a plurality of air holes are arranged in a matrix on the loading tray, and the diameter of the air holes is smaller than the particle size of the material. A protective ring is circumferentially arranged on the outer wall of the loading tray, and the axial height of the protective ring is not less than the axial height of the fixed cylinder.

[0012] In an alternative embodiment, a carrier is sleeved on the outer wall of the transmission sleeve, the carrier is located below the loading tray, and the outer diameter is larger than the outer diameter of the fixed cylinder.

[0013] In an alternative embodiment, a fixing ring is provided at the upper end of the inner positioning cylinder. The outer diameter of the fixing ring is not greater than that of the outer friction cylinder, and the upper end of the outer friction cylinder is fixed to the bottom wall of the fixing ring.

[0014] In an alternative embodiment, the horizontal height of the fixing cylinder is less than that of the fixing ring; Wherein, the fixing cylinder is axially adapted to be inclined relative to the outer friction cylinder to facilitate the loading and unloading of the loading tray.

[0015] In an alternative embodiment, a hot air blower is provided on one side of the drying oven. The hot air blower is communicated with the drying oven and conveys hot air.

[0016] In a second aspect, the embodiments of the present disclosure further provide a drying process for a drying device, and the drying process includes: Put the material into the loading tray, and the loading tray is sleeved on the outer wall of the transmission sleeve; When the temperature in the drying oven rises, the transmission sleeve expands and deforms due to heat and is in interference fit with the inner wall of the loading tray; When the rotating shaft drives the convex block to rotate, the convex block impacts the side wall of the sliding block to vibrate the loading tray; The sliding block slides away from the rotating shaft until it disengages from the convex block, and the rotating shaft drives the convex block to rotate relative to the inner positioning cylinder; When the rotating shaft drives the convex block to rotate 360° and then abuts against the sliding block again, the convex block impacts the side wall of the sliding block again, vibrating the loading tray again and driving the loading tray to rotate synchronously.

[0017] The beneficial effects of the present invention are as follows. The present invention provides a drying device and a drying process for the production of bio-based materials. Through the cooperation of the transmission sleeve, the loading tray and the linkage structure, the transmission sleeve expands due to heat and is in interference fit with the inner wall of the loading tray. When the rotating shaft rotates to make the convex block impact the sliding block, while vibrating the loading tray, the loading tray is driven to rotate synchronously with the rotating shaft; the positioning block pushes the sliding block to disengage from the convex block, and the rotating shaft drives the convex block to rotate idly relative to the inner fixing cylinder by 360° until the convex block impacts the sliding block again; by intermittently impacting the sliding block with the convex block, the materials in the loading tray slide relative to the loading tray, so as to vibrate the materials in the loading tray, thereby preventing the materials in the loading tray from sticking and caking with each other.

[0028] It has been found that in related technologies, drying is usually carried out by heating with a hot air blower. However, 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 viscous layer, and they are prone to caking after drying. And the existing drying equipment cannot avoid the caking of bio-based materials during the drying process. In related technologies, the bio-based materials (such as starch-based and cellulose-based materials) can be dispersed by stirring to prevent surface adhesion caused by residual moisture. However, the rotation of the stirring paddle will cause the bio-based materials (such as cellulose fibers) to break, reducing the mechanical properties. Therefore, the traditional stirring method is not applicable to the bio-based materials (such as starch-based and cellulose-based materials) of this embodiment.

[0029] Therefore, how to avoid the caking of bio-based materials during the drying process is a technical problem that urgently needs to be solved in this field.

[0030] Regarding the defects of the above solutions and the reasons for their occurrence, they are all the results obtained by the inventors after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure for the above problems should be the contributions made by the inventors to this disclosure during the disclosure process.

[0031] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0032] The following will describe in detail some embodiments of the present invention with reference to the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0033] As Figures 1 to 8 shown, at least one embodiment provides a drying device for the production of bio-based materials, including: a drying box 1, with a driving motor 2 arranged at the bottom thereof; the driving motor 2 is a low-speed motor, and the rotational speed of the rotating shaft 20 is 20 - 30 revolutions per minute. The drying box 1 is rectangular and is placed upright; a hot air blower 11 is arranged on one side of the drying box 1, and the hot air blower 11 is communicated with the drying box 1, and the hot air blower 11 is adapted to convey hot air into the drying box 1. Preferably, when it comes to cellulose-based materials, the temperature of the hot air conveyed by the hot air blower 11 into the drying box 1 is 55 - 80 °C.

[0034] Refer to the attached Figure 2, a partition plate 10, which is horizontally arranged inside the drying oven 1; a transmission sleeve 3, which is rotatably arranged on the partition plate 10 and sleeved on the outer wall of the rotating shaft 20 of the driving motor 2; the transmission sleeve 3 adopts a detachable structure. When the convex block 21 abuts against the sliding block 51, the transmission sleeve 3 rotates synchronously with the rotating shaft 20; when the convex block 21 disengages from the sliding block 51, the rotating shaft 20 rotates relative to the transmission sleeve 3. In this state, the rotating shaft 20 idles relative to the transmission sleeve 3. A convex block 21 is radially arranged on the outer wall of the rotating shaft 20; a carrier plate 4, which is sleeved on the outer wall of the transmission sleeve 3; the carrier plate 4 is parallel to the partition plate 10, and an axial fixed cylinder 40 is arranged, the fixed cylinder 40 is sleeved on the outer wall of the transmission sleeve 3, and there is a gap between the inner wall of the fixed cylinder 40 and the outer wall of the outer friction cylinder 32.

[0035] Refer to the appendix Figure 4 , a linkage structure 5, which is arranged inside the transmission sleeve 3; the linkage structure 5 includes: a sliding block 51, which is radially slidably arranged on the inner wall of the inner positioning cylinder 31 and faces the rotating shaft 20; the upper horizontal height of the sliding block 51 is the same as the upper horizontal height of the convex block 21; the lower end of the sliding block 51 extends towards the partition plate 10, and the axial width is greater than the axial width of the convex block 21; the driving motor 2 drives the rotating shaft 20 to rotate until the convex block 21 abuts against the sliding block 51, and the convex block 21 impacts the side wall of the sliding block 51 to vibrate the carrier plate 4. The convex block 21 impacts the sliding block 51 to vibrate the carrier plate 4, so that the materials in the carrier plate 4 move from the static state to the rotating state, thus realizing the effect of vibrating the materials in the carrier plate 4. An elastic member 52, which is arranged between the side wall of the sliding block 51 and the inner wall of the outer friction cylinder 32, and is suitable for pushing the sliding block 51 towards the rotating shaft 20; the elastic member 52 is a compression spring.

[0036] The hot air blower 11 is suitable for conveying hot air into the drying oven 1. When the temperature in the drying oven 1 rises to the preset temperature, the outer friction cylinder 32 expands and deforms due to heat and is in interference fit with the inner wall of the fixed cylinder 40; when the rotating shaft 20 drives the convex block 21 to rotate, the convex block 21 impacts the side wall of the sliding block 51 to vibrate the carrier plate 4; the rotating shaft 20 drives the convex block 21 to rotate and drives the outer friction cylinder 32, the fixed cylinder 40 and the carrier plate 4 to rotate synchronously. The sliding block 51 slides away from the rotating shaft 20 until it disengages from the convex block 21, and the rotating shaft 20 drives the convex block 21 to rotate relative to the inner positioning cylinder 31.

[0037] Through the cooperation of the transmission sleeve 3, the carrier plate 4 and the linkage structure 5, the transmission sleeve 3 expands due to heat and abuts against the inner wall of the carrier plate 4, and the rotating shaft 20 rotates until the convex block 21 abuts against the linkage structure 5, so that the carrier plate 4 rotates synchronously with the rotating shaft 20; by the intermittent impact of the convex block 21 on the sliding block 51, the materials in the carrier plate 4 slide relative to the carrier plate 4 to shake the materials in the carrier plate 4, thereby preventing the materials in the carrier plate 4 from sticking and caking with each other.

[0038] Refer to the appendixFigure 3 and Figure 4 The transmission sleeve 3 includes an inner positioning cylinder 31 and an outer friction cylinder 32, and a cavity 34 is provided 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, and the outer diameter of the fixing ring 310 is not greater 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 the horizontal height of the fixing ring 310; The fixed cylinder 40 is suitable for being tilted relative to the outer friction cylinder 32 in the axial direction, so as to facilitate the placement of the loading plate 4. The outer friction cylinder 32 is a heat expansion component, preferably, the outer friction cylinder 32 is silicone rubber, whose volume expansion rate can reach 5%-8% at 55-80°C, which can effectively fill the gap between the fixed cylinder 40. The outer friction cylinder 32 is deformed by heat expansion, so that the outer wall of the outer friction cylinder 32 and the inner wall of the fixed cylinder 40 are in interference fit and abutted, and when the outer friction cylinder 32 rotates, it drives the fixed cylinder 40 and the loading plate 4 to rotate synchronously.

[0039] Reference Figure 3 , a platform 33 is fixed on the outer wall of the transmission sleeve 3, and the platform 33 is located below the carrier plate 4, and the outer diameter is larger than the inner diameter of the fixed cylinder 40. The platform 33 is suitable for supporting the carrier plate 4. Among them, at room temperature, the outer friction cylinder 32 rotates relative to the carrier plate 4; when the carrier plate 4 is tilted relative to the platform 33, the carrier plate 4 is tilted relative to the horizontal plane, and the axis of the fixed cylinder 40 is tilted relative to the axis of the inner positioning cylinder 31. Since the outer friction cylinder 32 is a flexible part, the inner wall of the fixed cylinder 40 after tilting will squeeze the outer wall of the outer friction cylinder 32. The fixed cylinder 40 can be tilted relative to the outer friction cylinder 32 in the axial direction, which is convenient for taking and placing the carrier plate 4.

[0040] Reference Figure 5 A positioning block 53 is vertically fixed on the partition 10. The positioning block 53 extends axially along the inner positioning cylinder 31, and its horizontal height is lower than that of the protrusion 21. When the rotating shaft 20 drives the protrusion 21 to rotate, the positioning block 53 will not interfere with the circumferential rotation of the protrusion 21. 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 abuts against 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 to abut against the positioning block 53 (the protrusion 21 moves to the top of the positioning block 53), the positioning block 53 is suitable for pushing the sliding block 51 to slide radially outward, so that the sliding block 51 is separated from the protrusion 21, and the protrusion 21 continues to rotate over the sliding block 51, and the driving 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.

[0041] Reference appendix Figure 5 , in order to drive the sliding block 51 to slide radially outward, a first inclined surface 54 is provided on one side of the positioning block 53 close to the sliding block 51; a second inclined surface 510 matching the first inclined surface 54 is provided on the side wall of the sliding block 51; wherein, when the convex block 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 convex block 21.

[0042] Reference appendix Figure 3 . A plurality of air holes 41 are arranged in a matrix on the loading tray 4, and the diameter of the air holes 41 is smaller than the particle size of the material; a protective ring 42 is arranged circumferentially on the outer wall of the loading tray 4, and the axial height of the protective ring 42 is not less than the axial height of the fixed cylinder 40.

[0043] The specific working principle is as follows: Reference appendix Figure 6 , after the loading tray 4 is placed horizontally on the loading platform 33, the fixed cylinder 40 is synchronously sleeved on the outer wall of the outer friction cylinder 32. As the temperature in the drying oven 1 rises, the outer friction cylinder 32 expands and deforms due to heat and abuts against the inner wall of the fixed cylinder 40 with an interference fit, and the outer friction cylinder 32 drives the loading tray 4 to rotate synchronously. The rotating shaft 20 drives the convex block 21 to rotate synchronously until the convex block 21 abuts against the side wall of the sliding block 51. The rotating convex block 21 impacts the side wall of the stationary sliding block 51, thereby generating vibration. The rotating shaft 20 continues to rotate to drive the convex block 21, the sliding block 51, the outer friction cylinder 32, the fixed cylinder 40 and the loading tray 4 to rotate synchronously. Figure 6 In [description], F1 represents the rotation direction of the rotating shaft 20, and F2 represents the rotation direction of the outer friction cylinder 32. When the convex block 21 abuts against the sliding block 51, the rotation directions of F1 and F2 are the same.

[0044] Reference appendix Figure 7 , the convex block 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 (since the horizontal height of the positioning block 53 is lower than the horizontal height of the convex block 21, and the lower side wall of the sliding block 51 and the upper side wall of the positioning block 53 partially overlap axially); when the convex block 21 drives the sliding block 51 to continue to rotate, the positioning block 53 pushes the sliding block 51 to slide radially outward, ( Figure 7 in [description], F2 represents the outward sliding direction of the sliding block 51) at this time, the convex block 21 moves to directly above the positioning block 53, and the sliding block 51 is pushed outward by the positioning block 53, so that the sliding block 51 disengages from the convex block 21. Figure 7F1 in it represents the rotation direction of the rotating shaft 20. Since the convex block 21 is disengaged from the sliding block 51, at this time, the rotating shaft 20 only drives the convex block 21 to rotate, while the sliding block 51, the outer friction cylinder 32, the fixed cylinder 40 and the load tray 4 all remain stationary.

[0045] Refer to the appendix Figure 8 , when the convex block 21 is disengaged from the sliding block 51, the elastic member 52 pushes the sliding block 51 to slide inward for resetting ( Figure 8 F2 in it represents the direction of the sliding block 51 sliding inward for resetting). After the sliding block 51 is disengaged from the convex block 21, the convex block 21 rotates past the sliding block 51 and continues to rotate ( Figure 8 F1 in it represents the rotation direction of the rotating shaft 20). At this time, under the inertia effect, the inner positioning cylinder 31 and the outer friction cylinder 32 drive the sliding block 51 to rotate inertially relative to the positioning block 53 until the sliding block 51 is misaligned with the positioning block 53 ( Figure 8 in the sliding block 51 is located on the right side of the positioning block 53 and rotates to the left side of the positioning block 53 under the inertia effect); the rotating shaft 20 drives the convex block 21 to continue to rotate. At this time, the inner positioning cylinder 31, the outer friction cylinder 32 and the load tray 4 all remain stationary. After the rotating shaft 20 drives the convex block 21 to rotate one circle (i.e., rotate 360°), the convex block 21 hits the side wall of the sliding block 51 again. The rotating convex block 21 hits the side wall of the stationary sliding block 51, and vibration is generated again.

[0046] By intermittently hitting the sliding block 51 with the convex block 21 to generate vibration, and the vibration is transmitted to the load tray 4 through the transmission sleeve 3, so that the materials in the load tray 4 slide relative to the load tray 4 to shake the materials in the load tray 4, thereby preventing the materials in the load tray 4 from sticking to each other and caking.

[0047] At least one embodiment provides a drying process of a drying device, and the drying process includes: Put the materials into the load tray 4, and the load tray 4 is sleeved on the outer wall of the transmission sleeve 3; when the temperature in the drying box 1 rises, the transmission sleeve 3 expands and deforms due to heat and is in interference fit with the inner wall of the load tray 4; when the rotating shaft 20 drives the convex block 21 to rotate, the convex block 21 hits the side wall of the sliding block 51 to vibrate the load tray 4; the sliding block 51 slides away from the rotating shaft 20 to disengage from the convex block 21, and the rotating shaft 20 drives the convex block 21 to rotate relative to the inner positioning cylinder 31; when the rotating shaft 20 drives the convex block 21 to rotate 360° and abuts against the sliding block 51 again, the convex block 21 hits the side wall of the sliding block 51 again, vibrating the load tray 4 again and driving the load tray 4 to rotate synchronously.
