[0039] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0040] Please refer to Figures 1 to 7 In the first embodiment of the present invention, a scraper structure 10 is provided, wherein at least a portion of the scraper structure 10 extends between two adjacent rotating discs 20 of the dryer, and at least a portion of the scraper structure 10 extending between the two adjacent rotating discs 20 is adapted to the gap between the two adjacent rotating discs 20; wherein, along the extension direction from the center of the rotating disc 20 to the edge of the rotating disc 20, the width of at least a portion of the scraper structure 10 in the direction of the gap between the two adjacent rotating discs 20 gradually increases.
[0041] With the scraper structure 10 provided in this embodiment, a gap is formed between the rotating discs 20, and at least a portion of the scraper extends into the gap. In the extending direction from the center of the rotating disc 20 to the edge of the rotating disc 20, the width of the gap in the arrangement direction of the rotating discs 20 gradually increases. Since at least a portion of the scraper structure 10 extending into the gap is adapted to the gap, it is possible to clean the materials adhered to two adjacent rotating discs 20, so that other materials in the gap can also contact the rotating disc 20, thereby improving the drying efficiency of the dryer.
[0042] Specifically, the extending direction from the center of the rotating disk 20 to the edge of the rotating disk 20 is the radial direction of the rotating disk 20 .
[0043] Specifically, the rotating disk 20 is a circular ring structure, and the thickness of the rotating disk 20 gradually becomes thinner along the extending direction from the center to the edge of the rotating disk 20, so that the width of the gap between adjacent rotating disks 20 in this direction gradually increases.
[0044] Specifically, a rotating shaft 40 is provided inside the dryer, and a plurality of rotating discs 20 are sequentially sleeved on the rotating shaft 40, and the rotating discs 20 are driven to rotate by the rotating shaft 40. The rotating shaft 40 is driven to rotate by an engine, a motor or other structure, which is not limited here.
[0045] Specifically, the rotating disk 20 is connected to a heat source, or the rotating disk 20 itself can generate heat.
[0046] In this embodiment, the scraper structure 10 also includes a first scraper 11. The width of the first scraper 11 gradually increases along the extension direction from the center of the rotating disk 20 to the edge of the rotating disk 20. The first scraper 11 has a pushing surface 111 for contacting the material. The pushing surface 111 includes an inner concave surface or an outer convex surface. In this way, when the pushing surface 111 includes an inner concave surface, the pushing surface 111 can scrape up the material between the rotating disks 20, thereby breaking up the material, further improving the stirring effect of the scraper structure 10; when the pushing surface 111 includes an outer convex surface, the pushing surface 111 can distribute the material between the rotating disks 20 to both sides onto the rotating disks 20, thereby increasing the contact area between the material and the rotating disk 20 and improving the utilization rate of the heat source.
[0047] In this embodiment, the scraper structure 10 also includes a second scraper 12, which is connected to the first scraper 11, and at least a portion of the second scraper 12 extends into the gap between two adjacent rotating disks 20. The width of the second scraper 12 along the direction of the gap between the two adjacent rotating disks 20 is less than or equal to the width of the first scraper 11 along the direction of the gap between the two adjacent rotating disks 20; wherein the push surface 111 is located on the side of the first scraper 11 away from the second scraper 12, and the push surface 111 includes an inner concave surface that is concave toward the second scraper 12 or an outer convex surface that is convex away from the second scraper 12.
[0048] With such a setting, the second scraper 12 is connected to the first scraper 11, and the first scraper 11 can be set in the gap of the rotating disk 20 through the second scraper 12. Since the width of the second scraper 12 in the direction along the gap between two adjacent rotating disks 20 is less than or equal to the width of the first scraper 11 in the direction along the gap between two adjacent rotating disks 20, the second scraper 12 will not interfere with the movement of the rotating disk 20, and the stirring effect of the scraper structure 10 can be improved by setting the second scraper 12, further breaking up the material to improve the drying efficiency of the dryer.
[0049] In this embodiment, Figure 2 As shown, the pushing surface 111 is a first inner concave surface 1111, and the first inner concave surface 1111 is symmetrically arranged relative to the second scraper 12; or Figure 3As shown, the push surface 111 is a first convex surface 1112, and the first convex surface 1112 is symmetrically arranged relative to the second scraper 12; or Figure 4 , Figure 5 As shown, the pushing surface 111 includes a second inner concave surface 1113 and a second outer convex surface 1114 arranged along the radial direction of the rotating disk 20 . The second inner concave surface 1113 is symmetrically arranged relative to the second scraper 12 , and the second outer convex surface 1114 is symmetrically arranged relative to the second scraper 12 .
[0050] With such a configuration, when the push surface 111 is the first inner concave surface 1111, the first inner concave surface 1111 of the push surface 111 can scrape up the material between the rotating disks 20, thereby improving the stirring effect. When the push surface 111 is the first outer convex surface 1112, the push surface 111 can distribute the material between the rotating disks 20 to the rotating disks 20 to increase the contact area between the material and the rotating disks 20, thereby improving the utilization rate of the heat source. When the push surface 111 includes the second inner concave surface 1113 and the second outer convex surface 1114 arranged along the radial direction of the rotating disk 20, it can not only scrape up the material between the rotating disks 20, but also distribute the material between the rotating disks 20 to the rotating disks 20 to ensure the stirring effect and improve the utilization rate of the heat source.
[0051] Specifically, Figure 4 As shown, the push surface 111 can be configured such that the second inner concave surface 1113 is closer to the center of the disk than the second outer convex surface 1114; Figure 5 As shown, the push surface 111 can be configured such that the second outer convex surface 1114 is closer to the center of the disk than the second inner concave surface 1113; or, the second inner concave surface 1113 and the second outer convex surface 1114 can be alternately configured. The specific structure of the push surface 111 is not limited here and can be configured according to specific usage requirements.
[0052] In this embodiment, a material disturbance groove 112 is provided at the edge of the first scraper 11. In this way, the material between the rotating discs 20 can be further differentiated through the material disturbance groove 112, thereby improving the stirring effect of the scraper structure 10.
[0053] In this embodiment, there are multiple material disturbance grooves 112. The multiple material disturbance grooves 112 are arranged at intervals around the periphery of the first scraper 11. In this way, the multiple material disturbance grooves 112 can further separate the materials between the rotating discs 20, thereby improving the stirring effect of the scraper structure 10.
[0054] Alternatively, a part of the plurality of material disturbing grooves 112 are arranged at intervals along the radial direction of the rotating disc 20 on one side of the first scraper 11 close to one of the two adjacent rotating discs 20, and another part of the plurality of material disturbing grooves 112 are arranged at intervals along the radial direction of the rotating disc 20 on one side of the first scraper 11 close to the other of the two adjacent rotating discs 20. In this way, the edge of the first scraper 11 is concave-convex through the plurality of material disturbing grooves 112, so that the first scraper 11 is convenient for cleaning the material adhering to the rotating disc 20, thereby improving the heat exchange efficiency of the dryer.
[0055] In this embodiment, when the push surface 111 is an inner concave surface, the inner concave surface includes a first inclined surface and a second inclined surface connected to each other, and the angle between the first inclined surface and the second inclined surface is α, 30°≤α≤60°; when the push surface 111 is an outer convex surface, the outer convex surface includes a third inclined surface and a fourth inclined surface connected to each other, and the angle between the third inclined surface and the fourth inclined surface is β, 30°≤β≤60°. Through such an angle setting, when the push surface 111 is an inner concave surface, it is more convenient to scrape the material between the rotating discs 20, and when the push surface 111 is an outer convex surface, it is more convenient to distribute the material between the rotating discs 20 to both sides onto the rotating discs 20.
[0056] In this embodiment, the first scraper 11 is provided with a clamping member 113 adapted to the second scraper 12, and the clamping member 113 is clamped on the first scraper 11. In this way, the structure is simple, and the first scraper 11 and the second scraper 12 can be easily separated.
[0057] In this embodiment, the second scraper 12 is a flat plate structure, and the second scraper 12 is arranged parallel to the rotating surface of the rotating disk 20. In this way, the first scraper 11 and the second scraper 12 can be connected more conveniently, and the stability of the connection between the second scraper 12 and the first scraper 11 is improved in structure.
[0058] In this embodiment, a portion of the second scraper 12 extends into the gap between two adjacent rotating discs 20, another portion of the second scraper 12 extends out of the gap between two adjacent rotating discs 20, and another portion of the second scraper 12 is connected to the housing 31 of the dryer. In this way, the installation of the scraper structure 10 is achieved by connecting the second scraper 12 to the housing 31 of the dryer.
[0059] Specifically, the dryer is provided with a base 311, the shell 31 is connected to the base 311, a cavity is provided inside the base 311, the cavity is adapted to the size of the second scraper 12, an opening connected to the cavity is provided below the base 311, the second scraper 12 enters the cavity through the opening, a first mounting hole 121 is provided on the second scraper 12, and a second mounting hole 312 corresponding to the first mounting hole 121 is provided on the base 311, and the connecting piece passes through the second mounting hole 312 and the first mounting hole 121 in sequence, so that the scraper structure 10 is installed on the base 311.
[0060] Please refer to Figure 8 In the second embodiment of the present invention, a dryer is provided, and the dryer includes the scraper structure 10 provided in the first embodiment. Since at least a portion of the scraper structure 10 extending into the gap between the discs is adapted to the gap, the materials adhered to two adjacent rotating discs 20 can be cleaned, so that other materials can also directly contact the rotating discs 20 for heat exchange, thereby improving the drying efficiency of the dryer.
[0061] In this embodiment, the dryer includes a plurality of rotating discs 20, and at least a portion of the scraper structure 10 extends into the gap between two adjacent rotating discs 20. In this way, a scraper structure 10 is provided between each rotating disc 20, thereby improving the drying efficiency of the dryer.
[0062] In this embodiment, the dryer further includes a first push plate 32, which is disposed on the rotating disc 20. The first push plate 32 extends along the axial direction of the rotating disc 20, and the first push plate 32 is spaced apart from the scraper structure 10. In this way, the material in the dryer can be lifted by the first push plate 32, thereby breaking up the material and further improving the drying efficiency of the dryer.
[0063] Alternatively, the included angle between the first push plate 32 and the axis of the rotating disk 20 may be within a small angle range, that is, ±10°.
[0064] In this embodiment, the dryer further includes a second push plate 33, which is arranged on the rotating disc 20. The second push plate 33 is inclined at a preset angle to the circumference of the rotating disc 20, and the second push plate 33 is spaced apart from the scraper structure 10. In this way, since the second push plate 33 is inclined at a preset angle to the circumference of the rotating disc 20, during the movement, the second push plate 33 can squeeze the material, thereby pushing the material forward in the dryer. Specifically, the angle between the second push plate 33 and the axis of the rotating disc 20 is in the range of ±80°.
[0065] From the above description, it can be seen that the above-mentioned embodiment of the utility model achieves the following technical effects: it is capable of cleaning the materials adhered to two adjacent rotating discs 20, so that other materials between the rotating discs 20 can also directly contact the rotating discs 20, thereby improving the drying efficiency of the dryer.
