[0016] 4. The automatic feeding gunning machine for refractory maintenance of the furnace uses a spiral plate to push and rotate the outer push plate to push the conveyed material outward. The pushed material will contact the convex rotating plate driven by the drive motor. The rotation of the convex rotating plate will stir the material, further promote the mutual contact between the materials, accelerate the uniform mixing of the materials, and indirectly improve the working speed of the gunning.

[0017] 5. The automatic feeding gunning machine for furnace refractory maintenance uses a driving motor to drive the convex rotating plate to generate vibrations that are transmitted to the contact rod through a fixed method. The contact area between the contact rod and the material is large, which increases the effect of the vibration on the material, allowing the driving motor to drive the convex rotating plate to generate vibrations that better act on the material, allowing the mixed bubbles in the material to be discharged, which can enhance the effect of material gunning.

At the same time, the bottom rotating scraper plate 603 will push the edge material upward when it rotates.

[0023] A top rotating scraper plate 604 is fixedly connected to the top of the bottom rotating scraper plate 603. The top rotating scraper plate 604 is in a spiral shape opposite to the bottom rotating scraper plate 603. The rotation of the top rotating scraper plate 604 will press the material on the edge downward, and the edge of the movable bottom 602 will fit against the inner wall of the spraying material mixing tank 1.

[0024] The outer wall of the spraying material mixing tank 1 is fixedly connected with a spraying gun interface 8, and a valve is arranged inside the spraying gun interface 8. The spraying gun interface 8 is connected to the spraying gun so that the material can be sent into the spraying gun for spraying, and the position of the spraying gun interface 8 is flush with the connection between the top rotating scraper plate 604 and the bottom rotating scraper plate 603. When the movable bottom support 602 rotates, a large mutual squeezing force will be generated at the connection between the top rotating scraper plate 604 and the top rotating scraper plate 604. Opening the valve of the spraying gun interface 8 can allow the mixed material to be discharged to the spraying gun through the spraying gun interface 8 for spraying, and the material can be sent into the spraying gun interface, which can avoid residual material inside the spraying material mixing tank 1 due to adhesion, so that the material can be fully utilized to improve the speed of the spraying work.

[0025] The top of the bottom rotating scraper plate 603 is fixedly connected with a spiral fixing rod 605, and the outer wall of the spiral fixing rod 605 is fixedly connected with a spiral plate push 606. The spiral plate push 606 will be driven to rotate by the stirring motor 601 through the spiral fixing rod 605. The rotation of the spiral plate push 606 will transport the material at the bottom of the spraying material mixing tank 1 to the top. The outer wall of the spiral plate push 606 is fixedly connected with an outer push plate 607. The spiral plate push 606 rotates with the outer push plate 607.

[0026] When in use, first add the material into the feeding port 5, let the motor drive the twist rod inside the feeding pipe 3, under the action of the twist rod, the material can pass through the feeding pipe 3 and be automatically transported to the inside of the spraying material mixing tank 1, then, add a proper amount of water to the mixing tank, at the same time, start the stirring motor 601, after the stirring motor 601 is running, it will drive the bottom rotating scraper plate 603 to rotate through the movable bottom support 602, and in this process, it will also synchronously drive the top rotating scraper plate 604 to move together, so as to fully stir the material inside the spraying material mixing tank 1, in addition, the spiral plate push 606 will also be driven to rotate by the stirring motor 601 through the spiral fixing rod 605, the rotation of the spiral plate push 606 will transport the material at the bottom of the spraying material mixing tank 1 to the top, and the outer push plate 607 will push the transported material to the edge under the action of centrifugal force, so that the materials inside the spraying material mixing tank 1 can contact each other more evenly. , and during the rotation, the top rotating scraper plate 604 rotates to press the material on the edge downward, and the bottom rotating scraper plate 603 pushes the material on the edge upward, which will generate a large mutual squeezing force at the connection between the top rotating scraper plate 604 and the top rotating scraper plate 604. Opening the valve of the spraying gun interface 8 can allow the mixed material to be discharged to the spraying gun through the spraying gun interface 8 for spraying. When the material inside the spraying material mixing tank 1 continues to decrease, the top rotating scraper plate 604 and the bottom rotating scraper plate 603 will scrape the inner wall of the spraying material mixing tank 1, and under the action of rotation, the material will be pushed to the connection between the top rotating scraper plate 604 and the bottom rotating scraper plate 603, and finally, the material can be delivered into the spraying gun interface 8, allowing the spraying gun to penetrate into the kiln for spraying, which can effectively avoid residual material inside the spraying material mixing tank 1 due to adhesion, thereby ensuring that the material is fully utilized.

[0027] Example 2: Please refer to Figure 1-8 Based on the first embodiment, the present invention provides a technical solution: The auxiliary feeding mechanism 7 includes an annular rubber pad 701, which is fixedly connected to the top of the spraying material mixing tank 1. A top cover plate 702 is fixedly connected to the top of the annular rubber pad 701. The annular rubber pad 701 can absorb vibrations to avoid excessive vibration transmission. A blanking suction port 703 is provided on the top of the top cover plate 702, and the blanking suction port 703 is located at the bottom corresponding to the feeding pipe 3.

[0028] A water inlet is provided on the top of the top cover plate 702, and two barrier filters 705 are fixedly connected inside the top cover plate 702. Exhaust fans 704 are fixedly connected at the corresponding positions of the two barrier filters 705 on the top of the top cover plate 702. The exhaust fan 704 will discharge the air inside the spraying material mixing tank 1 to the outside, and an inhalation airflow will be generated at the blanking suction port 703 to inhale the delivered material to prevent the material from floating when the material is discharged and causing dust. When the exhaust fan 704 discharges the gas, it is blocked by the barrier filter 705 to prevent the internal material from being discharged with the airflow.

[0029] Two contact rods 706 are fixedly connected to the bottom of the top cover plate 702, and the contact rods 706 are located between the corresponding top rotating scraper plates 604 and the spiral plate pushers 606. The contact rods 706 increase the contact area with the material and can increase the effect of vibration on the material. The outer push plate 607 pushes the conveyed material outward, and the pushed material will contact the convex rotating plate 708 driven by the drive motor 707. The convex rotating plate 708 rotates and is driven to rotate to stir the contacted material. This stirring action further promotes the mutual contact between the materials, so that the materials can be more fully mixed together.

[0030] A driving motor 707 is fixedly connected to the bottom of the contact rod 706, and a convex rotating plate 708 is fixedly connected to the outer wall of the driving motor 707. The convex rotating plate 708 plays a role similar to a cam. The convex rotating plate 708 is fixedly connected to the output shaft of the driving motor 707. The driving motor 707 drives the convex rotating plate 708 to rotate, which will cause vibration. The contact rod 706 is fixedly connected to the blanking suction port 703, which will cause the blanking suction port 703 to vibrate together.

[0031] When in use, the exhaust fan 704 is started while the material is being fed in by the feeding pipe 3. The exhaust fan 704 will discharge the air inside the gunning material mixing tank 1 to the outside, thereby generating an inhaled airflow at the blanking suction port 703. When the material is fed to the top of the gunning material mixing tank 1 by the feeding pipe 3, the material is poured into the gunning material mixing tank 1 through the blanking suction port 703. The blanking suction port 703 will inhale the material into the gunning material mixing tank 1 to prevent the material from scattering during unloading and causing dust. At the same time, the driving motor 707 drives the convex rotating plate 708 to rotate. The convex rotating plate 708 plays a role similar to a cam, which will cause Vibration, which is fixedly connected to the blanking suction port 703 through the contact rod 706, will make the blanking suction port 703 vibrate together, and the material on the surface of the blanking suction port 703 will be loosened and sucked into the airflow, so as to prevent the material from adhering to the surface of the blanking suction port 703. When the exhaust fan 704 discharges gas, it will be blocked by the barrier filter 705 to prevent the internal material from being discharged with the airflow. After the blanking is completed, the exhaust fan 704 is turned off, and the convex rotating plate 708 is driven by the driving motor 707 to continuously vibrate. The shaking will make the material attached to the barrier filter 705 fall off from the barrier filter 705 naturally under the action of the shaking and return to the inside of the spraying material mixing tank 1.

[0032] When the spiral plate pusher 606 rotates, the conveyed material will be pushed outward through the outer push plate 607, and the pushed material will contact the convex rotating plate 708 driven by the driving motor 707. The convex rotating plate 708 rotates and is driven to rotate to stir the contacted material. This stirring action further promotes the mutual contact between the materials, allowing the materials to be more fully mixed together. Under the continuous rotation and stirring of the convex rotating plate 708, the contact between the materials is more frequent and close, thereby accelerating the uniform mixing process of the materials.

[0033] The driving motor 707 drives the convex rotating plate 708 to rotate. During this process, the vibration generated will be transmitted to the contact rod 706 through the fixed structure. Since the contact area between the contact rod 706 and the material is large, the effect of the vibration on the material is increased. In this way, the vibration generated by the convex rotating plate 708 driven by the driving motor 707 can better act on the material. This vibration will prompt the material particles to rearrange and distribute. Under the continuous action of the vibration, the material particles will undergo relative displacement and gradually tend to a more dense stacking state, which can effectively discharge the mixed bubbles in the material, thereby improving the quality and performance of the material and providing better materials for the subsequent spraying of the furnace.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
