[0016] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0017] Depend on Figures 1 to 4 It is known that a refractory brick drying cart with uniform heating includes a base 1, a circular cavity 2 on the base 1, cover plates 3 rotatably mounted at both ends of the cavity 2, a central shaft 4 at the center of the cavity 2, a heat source inside the central shaft 4, and multiple rotating cylinders 5 detachably placed inside the cavity 2, which surround the central shaft 4. Refractory bricks are placed inside the rotating cylinders 5. A connecting shaft 6 extending out of the end of the cavity 2 is provided at the end of the rotating cylinder 5. A bushing 7 rotating synchronously with the cover plate 3 is provided at the end of the cavity 2. Multiple gears 8 are provided around the bushing 7. After the gears 8 are connected to the connecting shaft 6, they form a structure in which the gears 8 and the rotating cylinders 5 rotate synchronously. A gear ring 9 is provided at the end of the cavity 2. The gear ring 9 meshes with the gears 8. When the cover plate 3 rotates, the gears 8 rotate, causing the rotating cylinders 5 to rotate inside the cavity 2.

[0018] In practical use, this utility model According to the size of the refractory bricks, adjust the position of the refractory bricks inside the rotating drum 5, and place the refractory bricks into the rotating drum 5 one by one. Place the rotating drum 5 into the cavity 2 and fix it. Connect the connecting shaft 6 with the gear 8, start the heat source, and heat and dry the refractory bricks. The multiple rotating drums 5 in the cavity 2 rotate during heating, and each rotating drum 5 rotates on its own axis, so that each refractory brick is heated evenly, ensuring the drying effect, thereby ensuring product consistency and improving product quality.

[0019] Multiple wheels 10 are provided under the base 1 to facilitate the movement of mobile devices to a suitable location.

[0020] The rotating cylinder 5 is equipped with multiple sets of limiting plates 11. Each set of limiting plates 11 forms a ring structure. The ring structure can limit the rotation of the rotating cylinder 5, making the rotating cylinder 5 more stable when rotating in the cavity 2.

[0021] The rotating drum 5 includes a fixed plate 12 at its inner end, with multiple connecting rods 13 extending from the periphery of the fixed plate 12. The connecting rods 13 are arranged parallel to the axis of the rotating drum 5, and multiple limiting rings 14 are provided on the multiple connecting rods 13. An end cap 15 is detachably provided at the outer end of the rotating drum 5. Multiple positioning holes 16 are provided on the fixed plate 12 and the end cap 15. Positioning rods 17 are inserted into the positioning holes 16. The multiple positioning rods 17 constitute a limit for the refractory brick, so that the position of the refractory brick inside the rotating drum 5 is fixed.

[0022] According to the size and specifications of the refractory bricks, the positioning rod 17 is inserted at the appropriate position to fix the position of the refractory bricks inside the rotating drum 5. The refractory bricks can remain stable when the rotating drum 5 rotates, avoiding shaking and damage to the refractory bricks.

[0023] The positioning hole 16 on the end cap 15 is a through hole, the positioning rod 17 protrudes outside the end cap 15, and the other positioning holes 16 are used to discharge excess gas generated during drying.

[0024] The end cap 15 has multiple threaded holes around its perimeter, and the outermost end of the rotating cylinder 5 has a through hole that mates with the countersunk hole. Screws are used to position the end cap 15.

[0025] The connecting shaft 6 is a hexagonal prism structure. The gear 8 has a hexagonal hole in the center that matches the connecting shaft 6. A limit hole 18 is opened on the connecting shaft 6. After the connecting shaft 6 passes through the gear 8, a limit pin passes through the limit hole 18, so that the rotating drum 5 cannot move axially.

[0026] Gear 8 and connecting shaft 6 are engaged by a hexagonal prism and hexagonal hole structure, so that the two rotate synchronously. Due to the meshing of gear 8 and gear ring 9, the rotating drum 5 can revolve around the sun and rotate on its own axis at the same time. The positional relationship between the refractory brick and the heat source is constantly changing, so that the heating is uniform.

[0027] A motor 19 is installed on the base 1. The motor 19 drives the bushing 7 to rotate. A connecting plate 20 is provided between the bushing 7 and the gear 8. The gear 8 rotates at the end of the connecting plate 20. The end of the connecting shaft 6 passes through the connecting plate 20 and is positioned by a limit pin to prevent the rotating drum 5 from coming off.

[0028] Motor 19 drives cover plate 3 and rotating drum 5 to rotate. Motor 19 is located outside cavity 2 for easy ventilation and heat dissipation.

[0029] Compared with the prior art, this utility model has the following beneficial effects: the refractory bricks can continuously change position during the heating and drying process, so that the position of the refractory bricks and the heat source are constantly changing, thereby ensuring the uniformity of heating of the refractory bricks, thereby improving the consistency and stability of the dried refractory bricks and improving product quality.
