[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0026] Reference Figure 1An electrically heated dryer includes an outer shell 1, a support 2, an inner shell 3, a stirring mechanism 4, a heating mechanism 5, and a driving mechanism 6. The outer shell 1 is arranged along the length of the support 2 and is fixed to the top of the support 2. The outer shell 1 is hollow inside and open at both ends. The inner shell 3 is also hollow inside and open at both ends. The diameter of the inner shell 3 is smaller than that of the outer shell 1, and it is rotatably connected inside the outer shell 1. The inner shell 3 is arranged along the length of the outer shell 1, and its length is longer than that of the outer shell 1. Both ends of the inner shell 3 extend outside the outer shell 1. The stirring mechanism 4 is arranged inside the inner shell 3 and is used to stir the magnesia-carbon brick granules. The heating mechanism 5 is arranged between the inner shell 3 and the outer shell 1 and is used to heat the magnesia-carbon brick granules in the inner shell 3. The driving mechanism 6 is arranged on the support 2 and is used to provide power to the inner shell 3.
[0027] Reference Figures 1-3 The inner shell 3 has a feed end at one end and a discharge end at the other end along its length. The stirring mechanism 4 includes spiral blades 41, a beater assembly 42, a stirring assembly 43, and a lifting plate 44. There are multiple spiral blades 41, which are uniformly fixed on the inner circumferential surface of the feed end of the inner shell 3. The beater assembly 42 is located inside the inner shell 3 on the side away from the feed end of the spiral blades 41. There are multiple sets of beater assemblies 42, four sets in this embodiment, which are uniformly fixed on the inner wall of the inner shell 3 along its circumference. Each set of beater assemblies 42 includes two beaters 421, which are spaced apart along the length of the inner shell 3. Each beater assembly 421 includes two hinge seats 4211 and a beater plate 4213. The two hinge seats 4211 are spaced apart along the length of the inner shell 3 and are respectively hinged to hinge rods 4212. The striking plate 4213 is rectangular in shape and has multiple through holes evenly spaced on it. The striking plate 4213 is positioned between two hinge seats 4211, and one end of the striking plate 4213 along its length is fixedly connected to two hinge rods 4212.
[0028] In operation, the operator places the magnesia-carbon brick granules to be dried into the inner shell 3 from the feed end and starts the drive mechanism 6. The drive mechanism 6 drives the inner shell 3 to rotate. As the inner shell 3 rotates, the magnesia-carbon brick granules move towards the discharge end along with the spiral blades 41. During the rotation of the inner shell 3, due to the gravity of the clapping plate 4213, the clapping plate 4213 can pat the magnesia-carbon brick granules while the inner shell 3 is rotating, spreading the magnesia-carbon brick granules evenly, increasing the force-bearing area of the magnesia-carbon brick granules, reducing accumulation, and making the magnesia-carbon brick granules heat evenly, thus improving the drying efficiency. After being patted, the magnesia-carbon brick granules enter the mixing component 43. With the rotation of the mixing component 43 and the lifting plate 44, the magnesia-carbon brick granules are further loosened, making the magnesia-carbon brick granules heat evenly. The magnesia-carbon brick granules also move towards the discharge end along with the lifting plate 44. Finally, the dried magnesia-carbon brick granules are discharged from the discharge end.
[0029] Reference Figure 2 and Figure 3 The stirring assembly 43 is located inside the inner shell 3 at the end of the tapping assembly 42 away from the spiral blade 41. Multiple sets of stirring assemblies 43 are arranged at even intervals along the length of the inner shell 3. Each set of stirring assemblies 43 includes a hexagonal frame 431, connecting rods 432, and an L-shaped plate 433. The center of the hexagonal frame 431 is located on the central axis of the inner shell 3. Three connecting rods 432 are present, each passing through one of the three diagonals of the hexagonal frame 431, with both ends of the connecting rods fixed to the inner wall of the inner shell 3. Stirring blades 434 are fixed to each side of the hexagonal frame 431, and stirring blades 434 are also fixed to the ends of the connecting rods 432 that protrude from the hexagonal frame 431. Multiple small holes 4341 are evenly distributed on the stirring blades 434 to improve the hot air flow rate, ensuring uniform heating of the magnesia-carbon brick granules and improving drying efficiency. There are six L-shaped plates 433, and the six L-shaped plates 433 are respectively set in the gaps where the three connecting rods 432 intersect. One end of the L-shaped plate 433 is fixedly connected to the intersection of the three connecting rods 432, so that they form a windmill shape, which is used to improve the stirring effect on the magnesia-carbon brick particles and improve the drying efficiency.
[0030] Reference Figure 2 Multiple lifting plates 44 are evenly fixed to the inner wall of the entire inner shell 3. Each lifting plate 44 includes a horizontal plate 441 and a vertical plate 442. One end of the horizontal plate 441 along its width direction is fixedly connected to the inner wall of the inner shell 3, and the other end is fixedly connected to one end of the vertical plate 442 along its width direction. The included angle between the horizontal plate 441 and the vertical plate 442 is 90-120°. Multiple small holes 4341 are evenly provided on both the horizontal plate 441 and the vertical plate 442 to facilitate increased hot air flow rate and improve the drying efficiency of the magnesia-carbon brick granules.
[0031] Reference Figure 1 and Figure 4 The heating mechanism 5 includes heating tubes 51 and a temperature control probe 52. Multiple heating tubes 51 are evenly spaced and fixed to the inner wall of the outer casing 1, and the heating tubes 51 are electrically controlled. Insulating rock wool (not shown in the figure) is fixed between the heating tubes 51 and the outer casing 1 on the inner wall of the outer casing 1 for further insulation. The temperature control probe 52 is fixed to the outer casing 1, with one end extending into the outer casing 1 for temperature monitoring.
[0032] Reference Figure 1 and Figure 4The drive mechanism 6 includes a motor 61, a first gear 62, a second gear 63, and a support assembly 64. The motor 61 is fixed at the feed end of the bracket 2, and its output shaft faces the inner shell 3. The first gear 62 is fixed on the output shaft of the motor 61, and the second gear 63 is fixed on the outer circumferential surface of the inner shell 3 at the end extending from the outer shell 1, with the first gear 62 and the second gear 63 meshing. There are two sets of support assemblies 64, which are respectively located at the feed end and the discharge end of the bracket 2, for supporting the inner shell 3. Each set of support assemblies 64 includes two support wheels 641 and a support ring 642. The two support wheels 641 are fixed at both ends of the bracket 2 along its width direction, and the support ring 642 is fixed on the outer circumferential surface of the inner shell 3 at the end extending from the outer shell 1, with the support ring 642 meshing with the two support wheels 641.
[0033] When the motor 61 is started, the output shaft of the motor 61 can drive the first gear 62 to rotate. Since the first gear 62 and the second gear 63 are meshed, the second gear 63 can also be driven to rotate, thereby causing the inner shell 3 to rotate and providing power. At the same time, the support ring 642 rotates, causing the support wheel 641 to also rotate, supporting the inner shell 3 and improving the stability of the inner shell 3.
[0034] The working principle of this utility model is as follows: The user puts the magnesia-carbon brick granules to be dried into the feed end of the inner shell 3, starts the heating mechanism 5, the heating mechanism 5 can heat the inner shell 3, and at the same time starts the motor 61. The motor 61 drives the inner shell 3 to rotate, which makes the magnesia-carbon brick granules move towards the discharge end with the spiral blades 41. They are then stirred by the beater component 42 and the stirring component 43 in sequence, and finally discharged by the lifting plate 44 to the discharge end, so that the magnesia-carbon brick granules are heated evenly, which helps to improve the drying efficiency.
[0035] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
