[0021] By rotating rotating rod 7, rotating rod 7 drives two gears 8 to rotate, the engagement of two gears 8 and tooth slot 12 drives sliding plate 5 to move up and down in vertical direction, so that sliding plate 5 moves upward when firebrick needs to enter drying oven 3, after firebrick enters drying oven 3, sliding plate 5 moves downward, guaranteeing the closure of drying oven 3, compared with traditional device, the up-and-down movement of sliding plate can be controlled by simple rotating action, without complex mechanical structure or external power source, easy to operate and efficient, sliding plate 5 can closely adhere to drying oven 3, effectively prevent heat loss and the entry of external impurities, guarantee the stability and efficiency of drying process.

[0022] Firstly, the staff starts motor three 20 through the external controller, the output shaft of motor three 20 rotates, and the rotating power is transmitted to the lead screw 23 through the belt four 21, the rotation of the lead screw 23 causes the two moving blocks 24 connected with it by screw to move left and right in horizontal direction, the movement of the moving block 24 drives the lifting frame 2 to move up and down through the hinged action of the connecting rod 25, so as to adjust the height of the drying box 3 to adapt to the height requirement of different equipment, when it is needed to convey the firebrick, start motor two 16 through the external controller, the output shaft of motor two 16 drives the leftmost rotating rod 17 to rotate, and then synchronously rotates all rotating rods 17 through the transmission action of belt three 19, the round roller 18 on the rotating rod 17 rotates, which provides power for the conveying of the firebrick, so that the firebrick can be conveyed to the drying box 3 smoothly, before the firebrick enters the drying box 3, it is needed to start motor one 10 through the external controller, the output shaft of motor one 10 rotates, drives the rotating rod 7 to rotate through the cooperation of belt two 11, drives the two gears 8 to rotate through the rotating rotating rod 7, the gear 8 is engaged with the tooth groove 12 on the left outer wall of the sliding plate 5, so as to drive the sliding plate 5 to move upward in vertical direction,

[0023] When the firebrick enters the drying box 3, rotate the rotating rod 7 again, so that the sliding plate 5 moves downward until it closely fits with the top of the drying box 3, to ensure the sealing of the drying box, then start the fan 14, the fan blade rotates rapidly, first inhales the fresh air or heated air on the right side of the fan into the fan, then blows out the air from the air outlet on the left side of the fan uniformly, forming a strong and stable air flow, and then providing a continuous and uniform heat source for the drying box 3 through the two staggered distributed resistance wires 15, when the hot air flow blown out by the fan 14 passes through the resistance wire 15, it will be heated rapidly and flow to the surface of the firebrick with a large amount of heat energy.

[0024] Among them, the top of the support one 1 is fixedly installed with the motor three 20, the top of the support one 1 is fixedly installed with two fixed blocks 22, the side close to each other of the two fixed blocks 22 is rotatably installed with the lead screw 23, the outer wall of the lead screw 23 is wound with the belt four 21 on the output shaft of the motor three 20, the outer wall of the lead screw 23 is threadedly sleeved with the two moving blocks 24, the top of the two moving blocks 24 is hingedly installed with the connecting rod 25, the top of the two connecting rods 25 is hingedly connected with the bottom of the lifting frame 2.

[0025] When the motor three 20 is started through the external controller, the rotation of its output shaft is transmitted to the lead screw 23 through the belt four 21, which ensures that the rotating power of the motor three 20 can be efficiently transmitted to the lead screw 23. The lead screw 23 is threadedly connected with the two moving blocks 24, and this connection enables the rotation of the lead screw 23 to be converted into the linear motion of the moving blocks 24. When the lead screw 23 rotates under the drive of the belt four 21, the two moving blocks 24 move horizontally leftward and rightward along the axial direction of the lead screw 23. With the movement of the moving blocks 24, they drive the two connecting rods 25 to move. Here, the connecting rod 25 serves to connect the moving blocks 24 and the subsequent mechanical structure. When the moving blocks 24 move leftward or rightward, the connecting rod 25 changes the angle accordingly, thereby driving the mechanical structure connected therewith to move up and down correspondingly. Compared with the traditional device, the device has higher flexibility and adaptability. By adjusting the rotating speed and direction of the motor three 20, the height of the lifting frame 2 can be accurately controlled, so that it can adapt to the height of other equipment in the whole refractory brick production process.

[0026] The motor one 10 is fixedly installed at the top of the drying box 3, and the output shaft of the motor one 10 is wound with the belt two 11 on the outer wall of the left rotating rod 7. The outer wall of each rotating rod 7 is wound with the belt one 9.

[0027] The motor one 10 is started through the external controller, and the output shaft of the motor one 10 rotates to drive the rotating rod 7 to rotate through the cooperation of the belt two 11, thereby providing power support for the heat preservation mechanism.

[0028] The drying box 3 is fixedly installed with the resting plate 13 on the inner wall, and the fan 14 is fixedly installed on the resting plate 13. Two resistance wires 15 are fixedly installed on the top inner wall of the drying box 3, and the two resistance wires 15 are designed to be staggered.

[0029] The resting plate 13, the fan 14, and the resistance wires 15 on the top inner wall together constitute an efficient and stable drying system. The design of the resting plate 13 not only provides a solid support surface for the refractory bricks, but also optimizes the spatial layout inside the drying box 3, ensuring the circulation of hot air inside and maximizing the drying efficiency. After the fan 14 is started, the fan blades rotate rapidly to first suck the fresh air or heated air on the right side of the fan into the fan, and then uniformly blow the air out of the air outlet on the left side of the fan, forming a strong and stable air flow. The two staggered resistance wires 15 provide a continuous and uniform heat source for the drying box 3. When the hot air flow blown by the fan 14 passes through the resistance wires 15, it is rapidly heated and carries a large amount of heat energy to the surfaces of the refractory bricks.

[0030] The lifting frame 2 has a motor 16 fixedly installed on its back. The top of the lifting frame 2 is recessed and has a groove design. Several rotating rods 17 are rotatably installed on the inner wall of the lifting frame 2. The back of the leftmost rotating rod 17 extends to the outside of the lifting frame 2 and is fixedly connected to the output shaft of the motor 16. A round roller 18 is fixedly sleeved on the outer wall of each rotating rod 17.

[0031] When motor 16 is started by the external controller, the output shaft of motor 16 immediately begins to rotate, directly driving the leftmost rotating rod 17 to rotate. This ensures the directness and efficiency of power transmission, reduces energy loss during transmission, and thus improves the overall efficiency of the drying device. As the rotating rod 17 rotates, the circular rollers 18 fixedly mounted on each rotating rod also rotate. The circular rollers 18 provide a stable and uniform conveying surface for the refractory bricks, ensuring that the refractory bricks can enter the drying chamber 3 at a uniform and stable speed. This avoids damage to the refractory bricks caused by uneven speed or shaking during the conveying process, ensuring the integrity and quality of the product.

[0032] Among them, the front of several rotating rods 17 extends to the outside of the lifting frame 2, and belts 3 19 are wrapped around the outer wall of each pair of corresponding rotating rods 17. The number of belts 3 19 is one less than the number of rotating rods 17.

[0033] By extending the front of several rotating rods 17 outside the lifting frame 2, and winding belts 19 around the outer walls of corresponding rotating rods 17, belts 19 not only transmit power, thus improving drying efficiency, but also ensure that the refractory bricks maintain a stable state during the drying process. This prevents deformation or damage caused by uneven forces during drying, thereby guaranteeing product quality and stability.

[0034] Working principle and usage process of this utility model:

[0035] First, the operator starts motor 20 via an external controller. The output shaft of motor 20 rotates, transmitting rotational power to lead screw 23 via belt 21. The rotation of lead screw 23 causes two threaded moving blocks 24 to move horizontally left and right. The movement of moving blocks 24, through the hinge of connecting rod 25, drives the lifting frame 2 to adjust the height of the drying chamber 3 to accommodate different equipment height requirements. When refractory bricks need to be conveyed, motor 16 is started via the external controller. The output shaft of motor 16 drives the leftmost rotating rod 17 to rotate, which, through the transmission of belt 19, causes all rotating rods 17 to rotate synchronously. The rollers 18 on the rotating rods 17 rotate accordingly, providing power for the conveying of refractory bricks, allowing them to be smoothly conveyed into the drying chamber 3. Before the refractory bricks enter the drying chamber 3, motor 10 needs to be started via the external controller. The output of motor 10... The shaft rotates, and with the cooperation of belt 11, it drives the rotating rod 7 to rotate as well. The rotating rod 7 drives the two gears 8 to rotate. The gears 8 mesh with the tooth grooves 12 on the outer left side of the sliding plate 5, thereby driving the sliding plate 5 to move vertically upward, making room for the refractory bricks to enter. After the refractory bricks enter the drying box 3, the rotating rod 7 is rotated again, causing the sliding plate 5 to move downward until it is tightly attached to the top of the drying box 3, ensuring the sealing of the drying box. Then, the fan 14 is started, and the fan blades rotate rapidly. First, fresh air or heated air from the right side of the fan is drawn into the fan. Then, this air is blown out evenly from the air outlet on the left side of the fan, forming a strong and stable airflow. Then, through two staggered resistance wires 15, a continuous and uniform heat source is provided in the drying box 3. When the hot airflow blown out by the fan 14 passes through the resistance wires 15, it is rapidly heated and carries a large amount of heat energy to each surface of the refractory bricks.
