[0022] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In the description of the present invention, if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, if the terms "first", "second", "third" appear, they are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0024] Embodiment 1:

[0025] like Figure 1 , 2 In the illustrated embodiment, rollers or tracks may be provided on the outer wall of the drum 101, and the drum 101 is mounted on the bracket, and the drum 101 is driven to rotate by external force. The material to be dried enters through the inlet at one end of the drum 101, and the heat generated by the heating device enters the drum 101 through the inlet or outlet of the drum 101. After the material in the drum 101 is heated, the moisture in the material is removed.

[0026] Several lifting components are arranged along the radial direction of the drum 101 on the inner wall of the drum 101, and are used to lift the materials to be dried in the drum 101, so as to increase the chances of the materials to be dried contacting with the hot air. Specifically, each lifting component includes several lifting plates 102, and each lifting plate 102 is evenly distributed along the axial direction of the inner wall of the drum 101, and each lifting plate 102 extends toward the inside of the drum 101. During operation, in order to ensure that the materials lifted from the bottom by each lifting plate 102 are lifted to a higher height, each lifting plate 102 is arranged in a curved surface shape, wherein the shape of the curved surface can be in the form of a non-rotating curved surface. When each lifting plate 102 is installed on the drum 101, the section where the edge of each lifting plate 102 contacts the drum 101 is perpendicular to the section where the contact part of each lifting plate and the inner wall of the drum 101 is located, and the bending direction of each lifting plate 102 is toward the rotation direction of the drum 101.

[0027] Each lifting plate 102 is arranged at a spatial angle α with the rotation center line 103 of the drum 101. The angle α may be preferably 5°-15° according to factors such as the regularity and moisture content of the material to be dried. The existence of the angle α enables, when each lifting plate 102 lifts the material, the lifted material, under the action of its own gravity and the inclined surface of the lifting plate 102, to make part of the material move in the direction of the drum 101 outlet when falling.

[0028] Embodiment 2:

[0029] On the basis of Example 1, Figure 1 In the illustrated embodiment, the lifting plates 102 of adjacent lifting assemblies are staggered along the viewing direction of the rotation centerline 103 of the drum 101. When in use, as the drum 101 rotates, the lifting plates 102 of each lifting assembly do not pick up materials at the bottom of the drum 101 at the same time, so as to reduce the load of the driving device that drives the drum 101 to rotate. At the same time, the materials lifted in the space of the drum 101 are more uniform.

[0030] Embodiment 3:

[0031] On the basis of Example 1 or 2, Figure 3 In the illustrated embodiment, a baffle 104 is provided at the edge of each lifting plate 102 facing the feed port. The presence of the baffle 104 ensures that when the material is lifted, the material movement will not be oriented toward the entrance of the drum 101, thereby reducing the time that the material to be dried stays in the drum 101 and improving work efficiency.

[0032] Embodiment 4:

[0033] On the basis of any one of embodiments 1-3, Figure 3 , 4 In the illustrated embodiment, in order to adjust the angle of the spatial intersection angle α between each lifting plate 102 and the rotation center line 103 of the drum 101, each lifting plate 102 is provided with a mounting rod 107 at the edge of one side of the inner wall of the drum 101, wherein the mounting rod 107 can be connected to the edge of the lifting plate 102 by welding, and the body of the drum 101 is provided with a mounting hole adapted to the mounting rod 107. When each lifting plate 102 is assembled with the drum 101, the mounting rod 107 can be inserted into the mounting hole, and after adjusting the angle of the lifting plate 102, the mounting rod 107 and the drum 101 are locked by the nut 105. In order to prevent the mounting rod 107 and the drum 101 from loosening during use, the edge of one side of the lifting plate 102 and the drum 101 in contact is set in an arc shape, so that the point of force of the lifting plate 102 and the drum 101 is at the connection part between the lifting plate 102 and the mounting rod 107.

[0034] like Figure 3 ,4 In the illustrated embodiment, in order to increase the strength of the connection point between the mounting rod 107 and the lifting plate 102, a first base 108 is provided at one end where the mounting rod 107 and the lifting plate 102 are connected, and the edge of the lifting plate 102 is connected to the end surface of the first base 108 by welding, thereby increasing the contact area and making the connection between the mounting rod 107 and the lifting plate 102 more secure;

[0035] In order to increase the connection strength between the drum 101 and the lifting plate 102, a second base 111 is provided on the inner wall of the drum 101. The second base 111 is connected to the inner wall of the drum 101 by welding, and the through hole at the second base 111 and the mounting hole should be concentric during installation. When the lifting plate 102 and the drum 101 are assembled, the mounting rod 107 is inserted into the through hole, the first base 108 is clamped in the countersunk hole of the second base 111, and the mounting rod 107 is locked to the drum 101 by the nut 105.

[0036] like Figure 4 In the illustrated embodiment, in order to further prevent the angle of the lifting plate 102 from changing during use, the surfaces of the first base 108 and the countersunk hole that contact each other are both provided with teeth that mesh with each other.

[0037] like Figure 3 , 4 In the illustrated embodiment, in order to increase the connection strength between the first base 108 and the lifting plate 102, a groove 109 is provided at the end surface of the first base 108, and the edge of the lifting plate 102 close to the inner wall of the drum 101 is clamped in the groove 109 and connected to the first base 108 by welding.

[0038] like Figure 3 In the illustrated embodiment, in order to prevent the nut 105 from loosening during use, a spring washer 106 is provided between the nut 105 and the outer wall of the drum 101 .

[0039] Embodiment 5:

[0040] On the basis of Embodiment 3 or 4, in order to increase the lifting efficiency of the material to be dried and prevent the material from flowing out from the gap between the lifting plate 102 and the inner wall of the drum 101, a flexible gasket is provided at the edge of the lifting plate 102 close to the inner wall of the drum 101. When the lifting plate 102 is adjusted at an angle and locked with the drum 101, the flexible gasket blocks the gap between the lifting plate 102 and the inner wall of the drum 101. The flexible gasket can be made of high temperature resistant rubber or silicone.

[0041] Embodiment 6:

[0042] On the basis of any one of embodiments 3-5, Figure 3In the illustrated embodiment, in order to facilitate locking between the mounting rod 107 and the drum 101, a clamping block 110 or a clamping hole is provided at the end of the mounting rod 107 away from the lifting plate 102, wherein the clamping block 110 or the clamping hole can be in the form of an external hexagon or an internal hexagon.

[0043] In order to facilitate the positioning of the lifting plate 102, the relative angles of the clamping block 110 or the clamping hole and the lifting plate 102 should be consistent. During the specific installation, the rotation angle of the wrench that fixes the clamping block 110 or the clamping hole can be used as the basis for adjusting the angle of the lifting plate 102.

[0044] The embodiments described above are only preferred specific implementation methods of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present utility model according to the technical solution and utility model concept of the present utility model, which should be covered by the protection scope of the present utility model.
