Description

Technical Field

[0001] This utility model relates to the field of refractory material production technology, specifically to a drying equipment for producing refractory materials. Background Technology

[0002] During the forming process, refractory blanks contain a certain amount of moisture. The presence of this moisture can affect the strength and stability of the blanks. Drying treatment can remove the moisture from the blanks and bring them to the moisture content required for firing.

[0003] Application No. 202422000904.6 discloses a drying equipment for producing refractory materials. By setting up a transmission mechanism, granular refractory materials can be placed on a placement plate. While being dried by a dryer, a motor is started to drive a reciprocating screw to rotate. As the reciprocating screw rotates, it drives a moving block to move back and forth along the trajectory of a sliding block and a sliding groove. The moving block then drives a linkage plate and a lever to move back and forth. The lever contacts the refractory material and disperses the accumulated refractory material, thereby preventing the refractory material from piling up.

[0004] The refractory materials mentioned above are piled up on the placement plate, which can easily affect the drying effect of the heating box. Moreover, when there are many materials, it is difficult to disperse them by moving the lever, resulting in uneven drying. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Please see Figures 1 to 4This utility model provides a technical solution: a drying equipment for producing refractory materials, including a drying box 1, with a drying chamber 2 inside the drying box 1. Heating plates 24 are installed inside the drying box 1 and on both sides of the drying chamber 2 to facilitate heating of the drying chamber 2 and the materials. An air groove 4 is provided inside the drying box 1 and at the top of the drying chamber 2. An air pump 5 is installed at the top of the drying box 1, with an air inlet pipe 6 fixedly connected to the input end of the air pump 5. One end of the air inlet pipe 6 is fixedly connected to the air groove 4 to extract air from the drying chamber 2, which helps to lower the air pressure and the boiling point of water, thereby accelerating the vaporization of water and the drying of materials. A stirring rod 7 is rotatably connected inside the drying chamber 2, and flaps 8 are installed on both sides of the stirring rod 7. A servo motor 30 is installed on one side, and the output end of the servo motor 30 is fixedly connected to the stirring rod 7 via a coupling, driving the stirring rod 7 to rotate and causing the flap plate 8 to flip the material, which helps to make the material heat more evenly. The flap plate 8 has multiple discharge holes 25 inside, allowing the material to pass through and ensuring the flow of the material during flipping. The stirring rod 7 is rotatably connected to one side of each adjacent flap plate 8, and stirring blades are installed on both sides of the stirring shaft 9, which facilitates the stirring of the material with the rotation of the stirring rod 7, making the mixture more even. A feed pipe 3 is installed at the top of the drying chamber 2 and on one side of the air trough 4. One end of the feed pipe 3 is fixedly connected to the feed hopper. An air trough 19 is opened inside the drying chamber 1 and on one side of the feed pipe 3. The drying chamber 1 has multiple ventilation holes 20 located between the drying chamber 2 and the air duct 19. A fan 21 is installed on the top of the drying chamber 1. A heating box 22 is fixedly connected to the output end of the fan 21. An air duct 23 is fixedly connected to one end of the heating box 22. One end of the air duct 23 is fixedly connected to the air duct 19. A heating element is installed inside the heating box 22. With the operation of the fan 21, the hot air heated by the heating box 22 is easily introduced into the air duct 19 through the air duct 23, and then enters the drying chamber 2 through the multiple ventilation holes 20 to dry the material. Valves are installed on one side of the feed pipe 3 and the air duct 23 to close the feed pipe 3 and the air duct 23 when the air pump 5 is running, ensuring the sealing of the drying chamber 2. The stirring rod 7 has a hollow groove 10 inside. A first rotating shaft 11 is rotatably connected inside the trough 10, and the first rotating shaft 11 is fixedly connected to the stirring shaft 9. A first bevel gear 12 is installed on the outer side of the first rotating shaft 11. A bracket 13 is installed inside the trough 10 and on one side of the first bevel gear 12. A second rotating shaft 14 is rotatably connected to one side of the bracket 13. A second gear 15 and a second bevel gear 16 are respectively installed on the outer side of the second rotating shaft 14. The second bevel gear 16 meshes with the first bevel gear 12. A support shaft 17 is fixedly connected to one side of the drying chamber 2 and inside the trough 10. A first gear 18 is fixedly connected to one end of the support shaft 17. The first gear 18 meshes with the second gear 15. The second gear 15 and the second bevel gear 16 mesh with the first gear 18 and the first bevel gear 12, respectively.The first rotating shaft 11 drives the support shaft 17. When the second gear 15 revolves with the stirring rod 7, it rotates under the action of the first gear 18, driving the first rotating shaft 11 and the stirring shaft 9 to rotate. This enhances the stirring effect on the material and prevents localized overheating. The support shaft 17 is aligned with the center line of the stirring rod 7, so that when the second gear 15 revolves with the stirring rod 7, it surrounds the first gear 18 and maintains meshing with it. A control panel 31 is installed on one side of the servo motor 30 in the drying chamber 1. The drying chamber 1 is located inside the drying cavity 2 at the bottom. The drying chamber 1 is equipped with a discharge port 26. Electric push rods 27 are installed on both sides of the bottom of the drying chamber 1, corresponding to the discharge port 26. The output ends of the two electric push rods 27 are fixedly connected to a support frame 28. A baffle 29 is installed at one end of the support frame 28, inside the discharge port 26. This allows the electric push rods 27 to drive the baffle 29 to rise or fall, closing or opening the discharge port 26, facilitating control of material discharge. Both the baffle 29 and the drying chamber 2 are fan-shaped. The discharge port 26 and the drying chamber 2 are both in contact with the flap 8, allowing the material to be fully turned over without obstructing the movement of the flap 8.

[0019] In summary, during operation, the refractory material drying equipment involves feeding the material into the drying chamber 2 inside the drying box 1 through the feed pipe 3. The heating plate 24 heats both the drying chamber 2 and the material. Simultaneously, the fan 21 introduces hot air heated by the heating box 22 into the drying chamber 2 through the air duct 23 and multiple ventilation holes 20 to dry the material. The servo motor 30 drives the stirring rod 7 to rotate, causing the flaps 8 on both sides of the stirring rod 7 to agitate the material. The stirring rod 7 has an internal slot 10, which is fixedly connected to the stirring rod 7. The second gear 15 and the second bevel gear 16 on the second rotating shaft 14 mesh with the support shaft 17 and the first gear 18 and the first bevel gear 12 on the outer side of the first rotating shaft 11, respectively. One end of the support shaft 17 is fixedly connected to the drying chamber 2 and does not contact the slot 10 or the stirring rod 7. Therefore, the slot 10... When the second rotating shaft 14 and the second gear 15 in the tank 10 revolve with the stirring rod 7, the support shaft 17 and the first gear 18 remain unchanged. The second gear 15 rotates by meshing with the first gear 18, which drives the second rotating shaft 14, the second bevel gear 16, the first bevel gear 12, the first rotating shaft 11, and the stirring shaft 9 to rotate. The stirring shaft 9 then stirs the material. After a period of time, the blower 21 is turned off, and the feed pipe 3 and the air pipe 23 are closed by the valve to seal the drying chamber 2. At the same time, the air pump 5 is started and the air is extracted from the drying chamber 2 through the air inlet pipe 6. The air pressure in the drying chamber 2 decreases accordingly, and the heating plate 24 is started to perform secondary drying on the material. After the drying is completed, the electric push rod 27 pushes the support frame 28 to move down, so that the baffle 29 on the support frame 28 separates from the discharge port 26, and the discharge port 26 can be opened to discharge the material.
