DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4 The present invention provides a disc dryer with a vertical flip rake shovel, comprising a drying cylinder 101, wherein a plurality of heating discs are arranged inside the drying cylinder 101, wherein the heating discs are divided into a small heating disc 102 and a large heating disc 103, wherein the large heating disc 103 is provided with an opening 104 for guiding the material, and a driving shaft 105 is rotatably connected to the interior of the drying cylinder 101, and further comprising:

[0023] A vertical flipping rake shovel assembly for guiding and conveying materials is provided above the small heating plate 102 and the large heating plate 103;

[0024] The vertical flip rake shovel assembly includes a mounting rod 201, one end of which is fixedly mounted on the outer side of the drive shaft 105. A plurality of rake plates 202 are evenly distributed on the outer side of the mounting rod 201. A connecting plate 203 is connected to the lower side of the rake plate 202 through an elastic component. A mounting plate 204 is provided on one side of the connecting plate 203. A rake blade 205 is mounted on the mounting plate 204 through a mounting member. A telescopic component for assisting the telescopic connection is provided between the connecting plate 203 and the mounting plate 204.

[0025] It should be noted here that during the operation of the disc dryer, the vertical flip rake shovel assembly allows the material to continuously flow through the entire dryer for drying and heating treatment. During the drying process, the elastic assembly and the telescopic assembly cooperate with each other to ensure the flipping and pushing effect of the material falling from the upper end of the heating disc, thereby reducing the effect of part of the material sticking to the heating disc due to the effect of the heating temperature, affecting the efficiency of material flipping and transportation.

[0026] The telescopic assembly includes multiple sets of sleeves 601 fixed on the connecting plate 203, and a slide rod 602 is slidably connected to the sleeve 601, and one end of the slide rod 602 is fixed to the mounting plate 204;

[0027] It should be noted that the sleeve 601 and the slide bar 602 allow the mounting plate 204 to contract toward the connecting plate 203 after receiving a force.

[0028] A first spring 603 is sleeved on the outer side of the sleeve 601, and the two ends of the first spring 603 are respectively abutted against the connecting plate 203 and the mounting plate 204;

[0029] It should be noted here that the first spring 603 facilitates elastic pushing of the mounting plate 204 after the relative contraction movement occurs.

[0030] The elastic assembly includes multiple groups of T-shaped rods 501 slidably connected to the harrow plate 202. One end of each group of T-shaped rods 501 is fixed to the upper end of the connecting plate 203. A second spring 502 is sleeved on the outer side of each group of T-shaped rods 501. The two ends of the second spring 502 are respectively set against the harrow plate 202 and the connecting plate 203.

[0031] It should be noted here that: in the process of flipping and conveying the material, the elastic pushing effect of the second spring 502 on the elastic component on the connecting plate 203 and the connection effect between the sleeve 601 and the slide rod 602 on the telescopic component are used to make the lower end of the rake leaf 205 installed on the mounting plate 204 remain against the upper end of the heating plate while the material is being stir-fried and conveyed. By maintaining the counteraction between the rake leaf 205 and the upper end of the heating plate, the flipping and pushing effect of the material falling from the upper end of the heating plate can be guaranteed.

[0032] The mounting member is a slot 3 provided at the lower end of the mounting plate 204 for mounting the rake leaf 205. The mounting plate 204 is provided with a position limiting assembly for limiting the position of the rake leaf 205 after the position is fixed.

[0033] It should be noted that the card slot 3 facilitates the card installation of the auxiliary rake leaf 205 .

[0034] The limiting assembly includes a threaded hole 401 formed on the mounting plate 204, the threaded hole 401 being in communication with the card slot 3, and a threaded pin 402 being threadedly engaged with the threaded hole 401;

[0035] It should be noted here that: when the threaded pin 402 is rotated, the threaded pin 402 and the threaded hole 401 are engaged with each other during the rotation, so that one end of the threaded pin 402 abuts against one side of the installed rake leaf 205, thereby limiting the installed rake leaf 205.

[0036] Working principle: During the operation of the disc dryer, the material to be dried is placed inside the drying cylinder 101. After placement, the driving shaft 105 is rotated. During the rotation of the driving shaft 105, the mounting rods 201 of each group of vertical flip-type rake shovel assemblies are driven to rotate. During the movement of the mounting rod 201, the connection between the elastic component and the components on the telescopic component drives the rake blades 205 installed on the mounting plate 204 to rotate, so that the rake blades 205 continuously turn the material, and in the process of turning, the material flows along the exponential spiral line across the surface of the heating plate. This flow mode helps the material to be evenly heated and dried during the drying process. At the same time, during the entire material conveying process, the outer edge of the material on the small heating plate 102 is transferred to the outer edge of the large heating plate 103 below, and moves inward on the large heating plate 103, and finally falls from the middle opening 104 into the small heating plate 102 of the next layer, so that the material can continuously flow through the entire dryer;

[0037] In the process of flipping and conveying the material, the second spring 502 on the elastic assembly pushes the connecting plate 203 and the connecting action of the sleeve 601 on the telescopic assembly and the slide rod 602, so that the lower end of the rake 205 installed on the mounting plate 204 is kept against the upper end of the heating plate while the material is being stir-fried and conveyed. The rake 205 and the upper end of the heating plate are kept against each other to ensure the flipping and pushing effect of the material falling from the upper end of the heating plate, thereby reducing the effect of part of the material sticking to the heating plate due to the effect of the heating temperature, which affects the efficiency of material flipping and conveying.

[0038] When the material is turned over and conveyed by the resistance of the rake leaf 205 against the upper end of the heating plate, when the adhesion effect between the turned and pushed material and the heating plate is strong and the rake leaf 205 cannot directly push and separate, the movement of the rake leaf 205 and the adhered material is blocked, and as the connecting plate 203 continues to move, the connecting plate 203 and the mounting plate 204 undergo relative contraction movement. During the contraction process, each group of slide bars 602 is pushed to slide on each group of sleeves 601 respectively, and the first spring 603 is deformed by force to generate elastic force. The elastic force of the first spring 603 squeezes and pushes the mounting plate 204 and the rake leaf 205 after the movement is blocked, thereby increasing the pushing effect of the rake leaf 205 on the adhered material and finally separating the adhered material from the heating plate, further ensuring the turning and conveying efficiency of the material during the heating process.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
