The traditional calcination method of oyster shells may have the disadvantage of uneven calcination, which is mainly due to the uneven and discontinuous heating of the oyster shells during the calcination process, low calcination efficiency, and this uneven calcination will cause the quality of the produced oyster shell powder to be unstable, which in turn affects the effect of its subsequent application. In addition, the feeding and discharging methods may not be convenient enough, resulting in low operating efficiency. At the same time, for the oyster shell powder produced during the calcination process, the traditional device may lack an effective collection mechanism, resulting in the scattering and waste of powder.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0030] A device for high temperature calcination of oyster shells, such as Figure 1-Figure 3As shown, it includes a calcining workbench 10 for calcining oyster shells, a metal conveyor mesh belt 20 is installed on the calcining workbench 10, a feed inclined plate 30 is installed on the top of one end of the metal conveyor mesh belt 20, a discharge inclined plate 40 is installed on the bottom of the other end of the metal conveyor mesh belt 20, and a powder collecting plate 50 is installed at the bottom of the calcining workbench 10; a gas conveying seat 11 is installed on the calcining workbench 10, the gas conveying seat 11 is arranged between the upper layer and the lower layer of the metal conveyor mesh belt 20, and a high-temperature flame nozzle 13 is installed on the top surface of the gas conveying seat 11. The arrangement of the metal conveyor mesh belt 20 allows the oyster shells to be evenly distributed on the calcining workbench 10, and as the mesh belt moves, the oyster shells can be gradually calcined. The continuous transmission design improves production efficiency and makes the calcination process more continuous and uniform. The arrangement of the feed inclined plate 30 and the discharge inclined plate 40 makes it more convenient to add and remove the oyster shells. The inclined design allows the oyster shells to slide in and out of the device smoothly, reducing the difficulty of manual operation and improving work efficiency. The powder collecting plate 50 is used to collect the oyster shell powder generated during the calcination process, avoiding the scattering and waste of the powder. At the same time, the design of the powder collecting plate 50 makes the collection of powder more concentrated and convenient, which is convenient for subsequent processing and utilization. The high-temperature flame nozzle 13 directly calcines the oyster shells at high temperature, so that the oyster shells can be heated quickly and evenly, improving the calcination effect and product quality.

[0031] Furthermore, fixed columns 12 are installed at the four top corners of the bottom of the calcining workbench 10, and moving wheels 14 are installed at the bottom of each fixed column 12, so that the entire device can be easily moved and positioned, thereby enhancing the flexibility and portability of the device and facilitating its use in different workplaces or production lines.

[0032] Specifically, conveying rollers 21 are installed at both ends of the metal conveying mesh belt 20. The metal conveying mesh belt 20 and the conveying rollers 21 are driven and connected to ensure stable conveyance of oyster shells during the calcination process, avoid blockage or jamming, and improve production efficiency.

[0033] It is worth noting that the spacing between the gas conveying seat 11 and the upper layer of the metal conveying mesh belt 20 is 8-12mm, which ensures that the oyster shells can be evenly heated during the calcination process and avoids the problem of excessive or insufficient heat concentration. The high-temperature flame nozzle 13 is made of brass, and the height of the high-temperature flame nozzle 13 is 2-4mm, which ensures that the flame can directly and effectively act on the oyster shells, thereby improving the calcination effect.

[0034] The inclination angles of the feed inclined plate 30 and the discharge inclined plate 40 are both 20-30°, so that the oyster shells can slide in and out of the device smoothly, reducing the difficulty of manual operation. At the same time, the appropriate inclination angle also helps to control the flow speed and distribution uniformity of the oyster shells during the calcination process.

[0035] In addition, a vibration motor 51 is installed on the bottom surface of the powder collecting plate 50 to help better collect and discharge the oyster shell powder generated during the calcining process through vibration.

[0036] The working principle of the device for high-temperature calcining oyster shells is as follows: the operator ensures that the calcining workbench 10, the metal conveyor mesh belt 20, the feed inclined plate 30, the discharge inclined plate 40, the powder collecting plate 50, the gas conveying seat 11 and the high-temperature flame nozzle 13 are all correctly installed and in good working condition, turns on the power supply of the calcining workbench 10 and the gas supply of the gas conveying seat 11, and evenly places the oyster shells on the starting end of the metal conveyor mesh belt 20 through the feed inclined plate 30. The metal conveyor mesh belt 20 starts to operate and conveys the oyster shells to the calcining workbench 11. 0, when the oyster shells are conveyed to the top of the gas conveying seat 11, the high-temperature flame nozzle 13 starts to work, spraying high-temperature flames to calcine the oyster shells. During the calcination process, the oyster shells are gradually calcined as the metal conveyor mesh belt 20 moves, realizing a continuous and uniform calcination process. The generated oyster shell powder will fall onto the powder collecting plate 50 for centralized collection. The calcined oyster shells are finally conveyed to the discharging inclined plate 40 through the metal conveyor mesh belt 20. The calcined oyster shells slide out of the device along the discharging inclined plate 40 to complete the discharging process.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
