[0027] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] Reference Figure 1 As shown, the present invention provides a disc dryer, comprising: a shell 1, a heating disc structure 3, a transmission shaft 2 and a raking device 4, wherein the heating disc structure 3 is fixedly arranged in the shell 1; the transmission shaft 2 is arranged in the shell 1 along the vertical direction, and the transmission shaft 2 is movably arranged in the heating disc structure 3; the raking device 4 comprises a mounting assembly 41 and a raking member 42, one end of the mounting assembly 41 is transmission-connected to the transmission shaft 2, and the other end abuts against the outer edge of the heating disc structure 3, and the mounting assembly 41 is mounted on the heating disc structure 3; the raking member 42 is detachably mounted on the mounting assembly 41, and a first gap is formed between the lower end of the raking member 42 and the bottom of the heating disc structure 3.

[0029] Specifically, the heating disc structure 3 is relatively fixedly arranged with respect to the shell body 1, and the raking device 4 is rotatably arranged on the transmission shaft 2. The raking device 4 includes a mounting assembly 41 and a raking member 42. The transmission shaft 2 drives the mounting assembly 41 to rotate, so as to drive the raking member 42 to rotate, thereby turning the material on the heating disc structure 3 to achieve drying of the material. The raking member 42 is detachably connected to the mounting assembly 41, and a first gap is formed between the lower end of the raking member 42 and the bottom of the heating disc structure 3, thereby avoiding damage to the material when the raking member 42 moves the material, and at the same time avoiding friction between the raking member 42 and the heating disc structure 3, generating foreign matter and debris, and affecting product quality.

[0030] It can be understood that the heating disc structure 3 and the transmission shaft 2 rotate relative to each other, the mounting assembly 41 is connected to the transmission shaft 2, the material falls on the heating disc structure 3, the transmission shaft 2 rotates to drive the mounting assembly 41 to rotate, thereby driving the rake member 42 to rotate, and there is a first gap between the rake member 42 and the heating disc structure 3. When the rake member 42 rotates, the material on the heating disc structure 3 is turned over to achieve uniform drying of the material. The first gap is set to avoid friction between the rake member 42 and the heating disc structure 3, avoid the generation of foreign debris, and at the same time avoid the rake member 42 from squeezing the material, causing the material to be crushed, affecting the quality of the finished product.

[0031] It should be noted that the mounting assembly 41, the rake blade member 42 and the heating disc structure 3 are all made of metal, and a high temperature and wear-resistant coating, such as a polytetrafluoroethylene coating, is provided on the surface to be suitable for a high temperature dry environment. The mounting assembly 41 abuts against the outer edge of the heating disc structure 3, and the use of wear-resistant materials can extend the service life and reduce the operation and maintenance costs.

[0032] In some embodiments of the present invention, a plurality of mounting components 41 and a plurality of raking leaf members 42 are provided, and the plurality of mounting components 41 located on the same horizontal plane are evenly spaced along the circumference of the transmission shaft 2 so as to be mounted on the heating disk structure 3, and a plurality of raking leaf members 42 are provided on the mounting components 41, and the plurality of raking leaf members 42 are evenly spaced along the length direction of the mounting components 41.

[0033] Specifically, multiple mounting components 41 and raking blade components 42 are provided, wherein multiple mounting components 41 located on the same horizontal plane are evenly spaced around the circumference of the transmission shaft 2, and multiple raking blade components 42 are provided on one mounting component 41 along its length direction, thereby ensuring that the material in the heating disk structure 3 is evenly turned over and the drying efficiency is improved.

[0034] In some embodiments of the present invention, the heating plate structure 3 includes a first heating plate 31 mounted on the transmission shaft 2, the first heating plate 31 includes a base plate 311 and a plate rack 312 arranged on the outer edge of the base plate 311, and a hollow gap is formed between the plate rack 312 and the base plate 311.

[0035] In some embodiments of the present invention, the heating plate structure 3 also includes a second heating plate 32 mounted on the transmission shaft 2, the first heating plate 31 and the second heating plate 32 are spaced apart in the vertical direction, the second heating plate 32 is located below the first heating plate 31, and a through hole is provided in the middle of the second heating plate 32.

[0036] Specifically, multiple first heating disks 31 can be provided, and a hollow gap is formed between the bottom plate 311 and the disk frame 312. The rake blades 42 turn the material during rotation, and the material easily falls from the hollow gap to the next first heating disk 31, thereby achieving multi-stage drying and improving the drying effect.

[0037] It can be understood that the heating disk structure 3 includes a first heating disk 31 and a second heating disk 32, and the first heating disk 31 and the second heating disk 32 are arranged at intervals in the vertical direction. The second heating disk 32 is located below the first heating disk 31. The material in the first heating disk 31 falls into the second heating disk 32 after primary drying to achieve secondary drying. A through hole is set in the middle of the second heating disk 32, and the dried material flows out from the through hole.

[0038] In some embodiments of the present invention, a plurality of first heating disks 31 and second heating disks 32 are provided, and the first heating disks 31 and second heating disks 32 are alternately arranged, and the material falls from the outside of the first heating disk 31 into the second heating disk 32, and after being turned and dried by the raking leaf member 42, falls from the through hole into the first heating disk 31 of the next level, thereby achieving repeated turning and drying of the material and improving the drying effect.

[0039] In some embodiments of the present invention, a feed port 11 is disposed at the top of the shell 1 , a discharge port 12 is disposed at the bottom of the shell 1 , and a diameter of the second heating disk 32 is greater than a diameter of the first heating disk 31 .

[0040] Specifically, a feed port 11 is arranged at the top of the shell 1, and a discharge port 12 is arranged at the bottom. By continuously supplying material to the feed port 11, continuous drying of the material can be achieved and the yield can be improved. It can be understood that the diameter of the second heating disk 32 is larger than the diameter of the first heating disk 31, so as to ensure that when the material falls from the outer edge of the first heating disk 31, it can fall into the second heating disk 32 to continue drying, thereby preventing the material from falling directly and flowing out of the discharge port 12, resulting in incomplete drying of the material and affecting the product quality.

[0041] In some embodiments of the present invention, the number of leaf raking devices 4 is equal to the sum of the number of first heating trays 31 and the number of second heating trays 32 , and the length of the mounting assembly 41 is greater than the radius of the second heating tray 32 .

[0042] Specifically, the length of the mounting assembly 41 is greater than the radius of the second heating plate 32, thereby ensuring that the mounting assembly 41 is mounted on the first heating plate 31 and the second heating plate 32, so that the forces at both ends of the mounting assembly 41 are balanced, avoiding excessive torque caused by unilateral force and bending deformation.

[0043] In some embodiments of the present invention, the second heating plate body 32 includes an outer edge portion and a plate bottom that are connected to each other, the outer edge portion extends upward and tilts from the inside to the outside, the other end of the mounting assembly 41 abuts against the upper end of the outer edge portion, and the plate bottom is concave and tilted downward from the outer edge toward the through hole.

[0044] Specifically, the second heating plate body 32 includes an outer edge portion and a plate bottom, which are integrally formed. The outer edge portion extends upward from the inside to the outside to form a flared setting to facilitate carrying of materials. The bottom of the plate is concave and inclined downward from the outer edge toward the through hole, thereby ensuring that the material can fall through the through hole.

[0045] In some embodiments of the present invention, the bottom plate 311 of the first heating plate body 31 is planar or inclined downward from the center toward the outer edge.

[0046] Specifically, a hollow gap is formed between the bottom plate 311 and the plate frame 312 of the first heating plate body 31. To facilitate the falling of materials from the hollow gap, the bottom plate 311 of the first heating plate body 31 is arranged to be flat or inclined downward from the center of the circle to the outer edge, thereby ensuring continuous drying of the material and avoiding accumulation of the material in the first heating plate body 31, which affects the drying efficiency.

[0047] Reference Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the mounting assembly 41 includes a mounting shaft 411, a rake frame 412 and a rake mounting plate 413, one end of the mounting shaft 411 is transmission-connected to the transmission shaft 2, and the other end of the mounting shaft 411 abuts against the outer edge of the heating disk structure 3;

[0048] A plurality of raking leaf racks 412 are provided along the length direction of the installation shaft 411 , one end of the raking leaf rack 412 is fixedly connected to the installation shaft 411 , and a raking leaf installation plate 413 is provided at the other end of the raking leaf rack 412 .

[0049] Specifically, in some embodiments of the present invention, the raking member 42 is provided with a plurality of first mounting holes 421 in the vertical direction, the raking mounting plate 413 is provided with a second mounting hole 4131, the raking device 4 also includes an adjusting fixture, which can be passed through the first mounting hole 421 and the second mounting hole 4131 to fix the raking member 42 on the raking mounting plate 413, and the raking member 42 is suitable for sliding in the vertical direction to adjust the width of the first gap.

[0050] It is understandable that by adjusting the fixing member, the rake member 42 is fixed to the mounting plate, and by adjusting the mounting height of the rake member 42, the width of the first gap is adjusted to adapt to materials of various specifications, ensure the completeness of the material drying, and avoid the material being squeezed and damaged.

[0051] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
