[0011] Compared with the prior art, the present invention has the following beneficial effects: 1.

This design not only eliminates the cumbersome transfer steps, saves time and manpower, but also ensures that the ceramic powder is evenly turned over in the cylinder and moves smoothly to one end through the rotation and tilting of the cooling cylinder, thereby realizing continuous and efficient cooling treatment and improving the practicality and efficiency of the entire purification and calcination process.

The arrangement of the heat conduction plate helps to transfer the heat of the ceramic powder inside the cooling cylinder to the outside during the cooling process, while the heat sink greatly increases the heat exchange area and accelerates the heat dissipation. In addition, a number of air vents are arranged inside the heat sink. Both the heat conduction plate and the heat sink are made of die-cast aluminum alloy. The design of the air vents promotes air circulation and further enhances the heat dissipation effect. The die-cast aluminum alloy material not only has good thermal conductivity, but also has high strength and corrosion resistance, which ensures the cooling cylinder's ability to dissipate heat outward and is beneficial to the rapid and uniform cooling of the ceramic powder.

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention.

[0017] See also Figure 1-5 An embodiment of the present invention is: a ceramic powder dry purification calcining device, comprising a calcining cylinder 3, an outer side of the calcining cylinder 3 is fixedly mounted with an external gear 13, the calcining cylinder 3 is tilted, a feed box 18 is rotatably mounted on one side of the lowest end of the calcining cylinder 3, a feed guide pipe 19 is fixedly mounted below the feed box 18, a cooling cylinder 4 is arranged on one side of the feed guide pipe 19, an outer side of the cooling cylinder 4 is fixedly mounted with an external gear 6, and the cooling cylinder 4 is tilted.

[0018] When in use, the calcining cylinder 3 and the cooling cylinder 4 can be driven to rotate by driving the outer gear 2 13 and the outer gear 1 6 to rotate respectively. When the ceramic powder is dry-process purified, the ceramic powder is input into the calcining cylinder 3 for calcination. The calcining cylinder 3 is rotated and tilted to move the ceramic powder to one end of the calcining cylinder 3, and then the calcined ceramic powder is directly input into the cooling cylinder 4 through the feed box 18 and the guide pipe 19. The cooling cylinder 4 is rotated and tilted to turn the ceramic powder over in the cooling cylinder 4 and move to one end for output, thereby realizing continuous and efficient cooling treatment and improving the practicality and efficiency of the entire purification and calcination process.

The four heat conduction plates 11 are respectively provided at the upper end, lower end and both sides of the cooling cylinder 4. A heat sink 12 is fixedly installed outside the heat conduction plate 11. Three heat sink 12 are provided.

[0020] The design of the heat conduction plate 11 fixedly installed inside the cooling cylinder 4 and the heat sink 12 outside it is beneficial to increase the heat exchange efficiency. The setting of the heat conduction plate 11 helps to transfer the heat inside the cooling cylinder 4 to the outside during the cooling process of the ceramic powder, while the heat sink 12 greatly increases the heat exchange area and accelerates the dissipation of heat, thereby improving the cooling efficiency and facilitating the rapid and uniform cooling of the ceramic powder.

[0021] Furthermore, a plurality of vent holes are provided inside the heat sink 12 , and the heat conduction plate 11 and the heat sink 12 are both made of die-cast aluminum alloy.

[0022] The design of the vents promotes air circulation and further enhances the heat dissipation effect. The die-cast aluminum alloy material not only has good thermal conductivity, but also has high strength and corrosion resistance, which ensures the outward heat dissipation ability of the cooling cylinder 4 and is beneficial to the cooling work of the ceramic powder after calcination.

[0023] Furthermore, a transmission gear 7 is meshedly installed below the external gear 6, and a gear rack 8 is symmetrically installed on both sides of the transmission gear 7 for rotation. A reducer 9 is provided on one side of the gear rack 8, and the output end of the reducer 9 is fixedly connected to the transmission gear 7, and a motor 10 is fixedly installed on one side of the reducer 9 through a coupling.

[0024] The driving structure composed of a transmission gear 7, a gear frame 8, a reducer 9 and a motor 10 realizes the driving of the cooling cylinder 4, ensuring the continuity and uniformity of the cooling process. At the same time, the use of the reducer 9 also plays a role in deceleration and torque increase, protecting the motor from the influence of excessive load and extending the service life of the equipment.

[0025] Furthermore, a transmission gear 14 is meshedly installed below the outer gear 13, and gear racks 15 are symmetrically installed on both sides of the transmission gear 14 for rotation. A reducer 16 is provided on one side of the gear rack 15, and the output end of the reducer 16 is fixedly connected to the transmission gear 14, and a motor 17 is fixedly installed on one side of the reducer 16 through a coupling.

[0026] The driving structure of the calcining tube 3, which is composed of the transmission gear 2 14, gear rack 2 15, reducer 2 16 and motor 2 17 below the outer gear 2 13, ensures that the calcining tube 3 can rotate at a predetermined speed and direction, promotes uniform heating and effective movement of the ceramic powder during the calcining process, and improves the calcining efficiency and quality.

[0027] Furthermore, a feeding pipe 1 is provided at one side of the highest end of the calcining tube 3 , and a gas burner 2 is provided below the feeding pipe 1 .

[0028] The setting of the feeding pipe 1 facilitates the continuous addition of ceramic powder into the calcining tube 3, and the gas burner 2 can spray fire into the calcining tube 3 to generate high-temperature flue gas in the calcining tube 3, which is beneficial to the heat calcination of the ceramic powder and increases practicality.

[0029] Furthermore, an exhaust port is provided above the feed box 18 , and the exhaust port is externally connected to a cyclone dust collector to facilitate the output and treatment of the gas in the calcining cylinder 3 . A discharge hopper 5 is provided below the lowest end of the cooling cylinder 4 .

[0030] The design of the exhaust port helps to discharge the gas generated during the calcination process, ensuring the safety of the working environment, while the discharge hopper 5 facilitates the smooth discharge of the cooled ceramic powder, improves production efficiency, and also facilitates the connection of subsequent processes.

[0031] Working principle: When in use, ceramic powder is continuously added into the inclined calcining cylinder 3 through the feeding pipe 1, and the gas burner 2 sprays fire into the calcining cylinder 3 to generate high-temperature flue gas, so that the ceramic powder is heated and calcined. The calcining cylinder 3 is driven by the external gear 13, and the transmission gear 14, the gear rack 15, the reducer 16 and the motor 17 are coordinated to realize rotation, so that the ceramic powder moves to one end of the calcining cylinder 3. After calcination, the ceramic powder directly enters the inclined cooling cylinder 4 through the rotating feeding box 18 and the guide pipe 19. The cooling cylinder 4 Driven by the external gear 6, the rotation is achieved through the cooperation of the transmission gear 7, the gear frame 8, the reducer 9 and the motor 10. At the same time, the heat transfer plate 11 inside the cooling cylinder 4 and the heat sink 12 outside work together to enhance the heat exchange efficiency and accelerate the heat dissipation, so that the ceramic powder turns over in the cooling cylinder 4 and moves to one end for rapid and uniform cooling. The cooled ceramic powder is discharged through the discharging hopper 5, thereby realizing the continuous and efficient purification, calcination and cooling treatment of the ceramic powder, and improving the practicality and efficiency of the whole process.
