Description

Technical Field

[0001] The utility model relates to the technical field of rare earth drying treatment, and particularly relates to a drying device for rare earth recovery. Background Art

[0002] The purpose of rare earth drying treatment is mainly to remove moisture in rare earth materials to improve the quality and stability of rare earth products. Wet rare earth will reduce its purity, increase impurity content, and affect the progress of chemical reactions, etc.

[0003] After retrieval, a patent with the application number CN201920883303.0 discloses a drying device for rare earth processing, whose structure includes support feet, a drying box, a viewing window, an air outlet, a feeding port, a discharge hopper, a fan, a heating box, a ventilation pipe, a control panel, a power plug, and a shaking mechanism. To solve the problem that the falling speed of rare earth is too fast, resulting in some rare earth not being completely dried when the rare earth falls into the discharge port, a shaking mechanism is arranged in the middle of the inner side of the drying box. When the motor works, the cam in the rotating rod is driven to rotate through the first transmission belt, and then the second cam is driven to rotate through the second transmission belt. The two cams rotate simultaneously to strike the shaking plate, causing it to rise and then reset and retract through the spring. Thus, when the rare earth falls on the upper end of the shaking plate, it bounces up to reduce the speed, and finally falls from both ends of the shaking plate, so as to achieve the effect of reducing the falling speed of rare earth and improving the drying efficiency.

[0004] The drying efficiency of the current rare earth drying device is slow. When the rare earth is heated and processed in the drying box, the fluidity of the rare earth is small (the rare earth is in a static state or undergoes a small-scale turning treatment), resulting in a small contact area between the rare earth and heat, which not only increases the drying time of the rare earth but also reduces the drying effect of the rare earth, resulting in insufficient dryness of the rare earth. Therefore, we need to propose a drying device for rare earth recovery. Content of the Utility Model

[0005] The purpose of the utility model is to provide a drying device for rare earth recovery. By designing to rotatably install an inner cylinder inside an outer cylinder and rotatably install a stirring mechanism inside the inner cylinder, heat is introduced into the gap between the inner cylinder and the outer cylinder to realize heat conduction to the rare earth in the inner cylinder and achieve drying of the rare earth. The turning plate arranged inside the inner cylinder can lift the rare earth to a certain height, and then the rare earth falls and impacts the inner wall of the inner cylinder and the convex blocks. This method increases the fluidity of the rare earth during the drying process inside the inner cylinder, and the surface of the rare earth will come into contact with heat, improving the rare earth drying efficiency; and when the rare earth falls, it will be impacted into fragments, and the rare earth will come into contact with the stirring mechanism, which can further break up the rare earth, further increasing the contact area between the rare earth and heat, and thus improving the drying effect of the rare earth, so as to solve the problems raised in the above background art.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figure 1-7 , the present invention provides a technical solution: a drying device for rare earth recovery, including a support plate 2, a base 6 is installed on the support plate 2, an outer cylinder 7 is installed on the base 6, an inner cylinder 8 is rotatably installed inside the outer cylinder 7, and a gap for heat flow is left between the inner wall of the outer cylinder 7 and the outer wall of the inner cylinder 8. The external heat is introduced into the gap by a fan, and the rare earth inside the inner cylinder 8 is heated and dried by heat conduction. A first driving mechanism 9 for driving the inner cylinder 8 to rotate is installed at one end of the support plate 2;

[0027] It should be noted that, as Figure 1 shown, a feed inlet is provided at the upper part of one end of the inner cylinder 8; as Figure 2 shown, a discharge outlet is provided at the lower part of the other end of the inner cylinder 8.

[0028] A plurality of turning plates 81 for lifting rare earth and a plurality of bumps 82 are respectively installed on the inner wall of the inner cylinder 8. A stirring mechanism 10 for crushing rare earth is rotatably installed inside the inner cylinder 8. A second driving mechanism 11 for driving the stirring mechanism 10 to rotate is installed at the other end of the support plate 2.

[0029] The turning plate 81 lifts the rare earth to a certain height. When the inner cylinder 8 rotates more than 90 degrees (i.e., when the rare earth is at the position diagonally above the inner cylinder 8), the rare earth slides down along the turning plate 81 and falls back to the inner bottom of the inner cylinder 8.

[0030] The rotating shaft 101 rotates, thereby driving the stirring rod 102 to rotate, causing the rare earth to collide with the stirring rod 102, and the stirring rod 102 can break the rare earth.

[0031] The first driving mechanism 9 includes a first fixing block 91 installed on the support plate 2, a first mounting plate 92 is installed on the first fixing block 91, and a first motor 93 is installed on the first mounting plate 92.

[0032] A second gear 96 is sleeved on the output shaft of the first motor 93. A rotating column 94 is connected to the center position of one end of the inner cylinder 8. A first gear 95 is sleeved on the outer wall of the rotating column 94, and the first gear 95 meshes with the second gear 96.

[0033] The first motor 93 drives the second gear 96 to rotate. Under the cooperation of the meshing of the first gear 95 and the second gear 96, the rotating column 94 is driven to rotate, and then the inner cylinder 8 is driven to rotate.

[0034] The stirring mechanism 10 includes a rotating shaft 101 rotatably installed inside the inner cylinder 8. A plurality of groups of stirring rods 102 arranged at equal intervals in a ring shape are connected to the outer wall of the rotating shaft 101. The stirring rods 102 can break up the rare earth, increasing the contact area between the rare earth and the heat.

[0035] The second driving mechanism includes a second fixing block 111 installed on the support plate 2. A second mounting plate 112 is installed on the second fixing block 111, and a second motor 113 is installed on the second mounting plate 112.

[0036] One end of the output shaft of the second motor 113 is sleeved with a fourth gear 115, and one end of the outer wall of the rotating shaft 101 is sleeved with a third gear 114. The third gear 114 meshes with the fourth gear 115.

[0037] The second motor 113 drives the rotating shaft 101 to rotate through the third gear 114 and the fourth gear 115.

[0038] It further includes a bottom plate 1. A first support block 3 and a second support block 4 are respectively installed at both ends of the surface of the bottom plate 1. One end of the support plate 2 is rotatably installed on the first support block 3, the other end of the support plate 2 is lapped on the second support block 4, and a cylinder 5 is rotatably installed at a position between the bottom plate 1 and the support plate 2 close to the second support block 4.

[0039] After drying is completed, operate the cylinder 5. The cylinder 5 can lift one end of the support plate 2, causing the inner cylinder 8 to tilt. Then open the sealing door on the discharge port, and the dried rare earth can be discharged.

[0040] During use, the rare earth is added into the inner cylinder 8 from the feed port, and heat / hot air (the generation of hot air can install electric heating coils in a box body and heat the air in the box body through the electric heating coils. This is prior art and not shown in the figure) is introduced into the gap between the outer cylinder 7 and the inner cylinder 8. The heat is introduced into the inner cylinder 8 through the outer shell of the inner cylinder 8 to realize the heating of the rare earth;

[0041] Then drive the inner cylinder 8 to rotate. Specifically, the first motor 93 drives the second gear 96 to rotate. Under the cooperation of the meshing of the first gear 95 and the second gear 96, the rotating column 94 is driven to rotate, and then the inner cylinder 8 is driven to rotate. The turning plate 81 inside the inner cylinder 8 is used to lift the rare earth to a certain height. When the inner cylinder 8 rotates more than 90 degrees, the rare earth slides down along the turning plate 81 and falls back to the inner bottom of the inner cylinder 8 again, realizing the continuous flow of the rare earth and reducing the contact dead angle between the rare earth and the heat;

[0042] Drive the stirring mechanism 10 to rotate simultaneously. Specifically, the second motor 113 drives the rotating shaft 101 to rotate through the third gear 114 and the fourth gear 115, and then drives the stirring rod 102 to rotate, causing the rare earth to collide with the stirring rod 102. The stirring rod 102 can break up the rare earth. At the same time, after the rare earth falls, if it contacts the convex block 82, it will also be broken by the convex block 82, making the rare earth into smaller particles, increasing the contact area between the rare earth and heat, and improving the drying effect on the rare earth.

[0043] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
