[0003] Existing drying equipment generally suffers from low thermal efficiency, difficulty in handling high-viscosity materials, and uneven drying that easily leads to agglomeration, which in turn affects the use of subsequent materials and causes losses. Therefore, this application proposes a rotary drying oven for the preparation process of inorganic pigments. Utility Model Content

The servo motor is mounted on the top of the positioning seat.

[0007] By adopting the above technical solution, a servo motor can be driven to rotate the gear, which in turn can work with the gear ring to rotate the drying furnace body on the outer edge of the positioning seat, thus achieving rotation. Furthermore, the lifting plate can continuously scatter the material inside the drying furnace body to form a material curtain.

[0008] In a preferred embodiment, a feed pipe is installed on one side of the drying furnace body, a sealing cover is installed on the other side of the drying furnace body, a discharge pipe is installed on the outer wall of the sealing cover, and a control valve is rotatably installed on the inner wall of the discharge pipe.

[0009] By adopting the above technical solution, external materials can be added into the interior of the drying furnace through the feed pipe, and then the processed materials inside the drying furnace can be discharged to the outside through the discharge pipe, thus achieving material discharge.

[0010] In a preferred embodiment, a positioning frame is installed on the outer wall of the sealing cover, the end of the air tube near the rotating tube is fixedly connected to the inner wall of the positioning frame, and the air pump is fixedly connected to the outer wall of the sealing cover.

[0011] By adopting the above technical solution, it can be used to position the trachea, ensuring that the trachea delivers gas inside the rotating tube and that the rotating tube does not interfere with the trachea when it rotates, thus ensuring the stability of its operation.

[0012] In a preferred embodiment, the drive unit includes a driven wheel fixed to the outer edge of the rotating tube, a stepper motor is mounted on the outer wall of the sealing cover, the power output shaft of the stepper motor is fixedly connected to a driving wheel, and a transmission belt is sleeved on the inner wall of the driving wheel and the driven wheel.

The spiral blades can move the material inside the drying furnace to different positions, ensuring the uniformity of drying and heating.

[0014] In a preferred embodiment, the outer edge of the rotating tube is provided with multiple air outlets, which are connected to the rotating tube and the air pipe.

[0015] By adopting the above technical solution, the gas inside the rotating tube can be discharged into the interior of the drying furnace through multiple air outlets, thereby allowing the interior of the drying furnace to be cleaned by blowing air when the sealing cover is opened, thus ensuring the cleanliness of the interior of the drying furnace.

[0016] In a preferred embodiment, the outer wall of the sealing cover is fixedly connected to the outer ring of the bearing, and the rotating tube is fixedly connected to the inner ring of the bearing.

[0017] By adopting the above technical solution, it can be used to position the rotating tube, ensure the stability of the rotating tube during rotation, and ensure that the rotating tube will not easily shift or swing in position during rotation.

[0018] The beneficial effects of this application are: This rotary drying oven in the preparation process of inorganic pigments drives a servo motor to rotate a gear, which in turn drives the drying oven body to rotate at the outer edge of the positioning seat in conjunction with a gear ring. This rotation is achieved by the lifting plates continuously scattering the material inside the drying oven body to form a material curtain, and can separate the material to prevent it from sticking and clumping. At the same time, the spiral blades can move the material inside the drying oven body to different positions to ensure the uniformity of drying and heating.

[0019] This rotary drying oven in the preparation process of inorganic pigments uses a driving air pump to deliver gas into the interior of the rotary tube through an air pipe. The gas is then sprayed through multiple spiral blades to clean the interior of the drying oven, thus ensuring the cleanliness of the interior of the drying oven. Attached Figure Description

[0022] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0023] Reference Figure 1-4A rotary drying oven for the preparation of inorganic pigments includes a drying oven body 1, an insulation jacket 2 installed inside the drying oven body 1, a stainless steel inner cylinder 3 installed inside the insulation jacket 2, a sealing cover 9 threadedly connected to the inner wall of the stainless steel inner cylinder 3, a positioning seat 4 rotatably installed at the bottom of the drying oven body 1, a driving mechanism installed at the top of the positioning seat 4, a rotating tube 12 rotatably installed on the inner wall of the sealing cover 9, a spiral blade 13 installed on the outer edge of the rotating tube 12, one end of an air pipe 14 rotatably inserted into the inner wall of the rotating tube 12, the other end of the air pipe 14 being fixedly connected to the output end of an air pump 15, a driving part installed on the outer wall of the sealing cover 9, and multiple lifting plates 22 installed on the inner wall of the drying oven body 1.

[0024] See Figure 1 and Figure 2 The driving mechanism includes a gear ring 5, which is installed on the outer wall of the drying furnace body 1. A gear 6 meshes with the outer edge of the gear ring 5. The power output shaft of the servo motor 7 is fixedly connected to one side of the gear 6. The servo motor 7 is installed on the top of the positioning seat 4, so that the servo motor 7 can drive the gear 6 to rotate. In turn, the gear ring 5 can drive the drying furnace body 1 to rotate at the outer edge of the positioning seat 4, thereby achieving rotation. Furthermore, the lifting plate 22 can continuously throw the material inside the drying furnace body 1 to form a material curtain.

[0025] See Figure 1 and Figure 3 A feed pipe 8 is installed on one side of the drying furnace body 1, and a sealing cover 9 is installed on the other side of the drying furnace body 1. A discharge pipe 10 is installed on the outer wall of the sealing cover 9, and a control valve 11 is rotatably installed on the inner wall of the discharge pipe 10, so that external materials can be added into the interior of the drying furnace body 1 through the feed pipe 8, and then the processed materials inside the drying furnace body 1 can be discharged to the outside through the discharge pipe 10 to achieve material discharge.

[0026] See Figure 3 A positioning frame 16 is installed on the outer wall of the sealing cover 9. The end of the air pipe 14 near the rotating pipe 12 is fixedly connected to the inner wall of the positioning frame 16. The air pump 15 is fixedly connected to the outer wall of the sealing cover 9, so that it can be used to position the air pipe 14. This ensures that the air pipe 14 will not interfere with the air pipe 14 when it is delivering gas to the inside of the rotating pipe 12 and when the rotating pipe 12 is rotating, thus ensuring the stability of its operation.

[0027] See Figure 3 and Figure 4The drive unit includes a driven wheel 17, which is fixed to the outer edge of the rotating tube 12. A stepper motor 20 is installed on the outer wall of the sealing cover 9. The power output shaft of the stepper motor 20 is fixedly connected to the drive wheel 19. A transmission belt 18 is sleeved on the inner wall of the drive wheel 19 and the driven wheel 17, so that the stepper motor 20 can drive the drive wheel 19 to rotate, and then the driven wheel 17 can be driven to rotate by the transmission belt 18. This can further drive the rotating tube 12 and the spiral blades 13 to rotate. The spiral blades 13 can move the material inside the drying furnace 1 to different positions to ensure the uniformity of drying and heating.

[0028] See Figure 4 The outer edge of the rotating tube 12 is provided with multiple air outlets 21, which are connected to the rotating tube 12 and the air pipe 14. This allows the gas inside the rotating tube 12 to be discharged into the interior of the drying furnace 1 through the multiple air outlets 21. This enables the interior of the drying furnace 1 to be cleaned by blowing air when the sealing cover 9 is opened, thereby ensuring the cleanliness of the interior of the drying furnace 1.

[0029] See Figure 3 and Figure 4 The outer wall of the sealing cover 9 is fixedly connected to the outer ring of the bearing, and the rotating tube 12 is fixedly connected to the inner ring of the bearing, so that the rotating tube 12 can be used to position the rotating tube 12, ensuring the stability of the rotating tube 12 when rotating, and ensuring that the rotating tube 12 will not easily shift or swing in position when rotating.

[0030] Working principle: First, the material to be processed can be added into the drying furnace body 1 through the feed pipe 8, and then dried. Then, the servo motor 7 drives the gear 6 to rotate, which in turn works with the gear ring 5 to rotate the drying furnace body 1 at the outer edge of the positioning seat 4. Further, the lifting plate 22 can continuously scatter the material inside the drying furnace body 1 to form a material curtain, and drive the stepper motor 20 to drive the drive wheel 19 to rotate, which in turn uses the transmission belt 18 to drive the driven wheel 17 to rotate, which in turn drives the rotating tube 12 and the spiral blades 13 to rotate. The spiral blades 13 can move the material inside the drying furnace body 1 to different positions to ensure the uniformity of drying and heating. Further, the material inside the drying furnace body 1 can be discharged to the outside through the discharge pipe 10. At the same time, the sealing cover 9 can be removed, and then the air pump 15 works with the air pipe 14 to deliver gas into the rotating tube 12, which can then be sprayed through multiple spiral blades 13 to clean the inside of the drying furnace body 1, thus ensuring the cleanliness of the inside of the drying furnace body 1.
