This utility model relates to the field of bamboo aggregate preparation technology, specifically to a system for utilizing waste heat from bamboo leaf ash preparation flue gas. The system includes a calcining furnace, a drying device, and a drying tower. The calcining furnace is connected to the drying device and the drying tower. A partition plate is installed inside the calcining furnace, dividing it into a first chamber and a second chamber. A preparation cylinder is installed in the second chamber and is detachably mounted on the partition plate. Several through holes are provided on the partition plate, and the first chamber communicates with the second chamber through these through holes. The system also includes a collector, pipe A, and pipe B. The collector communicates with the second chamber, and the end of pipe B communicates with the drying tower. This system solves the problems of low energy utilization efficiency in the preparation of functional additives in bamboo aggregate concrete production, lack of waste heat recovery from bamboo leaf calcination, and energy waste caused by fragmented heat supply in various process stages.

This invention relates to the field of gold extraction technology and discloses an automated fire testing system, comprising a manual operation area, a sample mixing and melting area, and an ash blowing area. Centered on the manual operation area, a crucible preparation area is connected in series with the starting point of the sample mixing and melting area. The process areas of the sample mixing and melting area are linearly distributed and unidirectionally connected. The melting furnace is located at the far end of the manual operation area and is connected in series with the backup area of ​​the manual operation area via an AGV, forming a closed loop. The ash blowing area is divided into a buffer area, an ash preparation area, and a processing area. The buffer area and the processing area are bidirectionally connected in a closed loop. A novel automated equipment layout is implemented to optimize temperature and process flow, reducing the impact on manual labor while shortening the conveying distance. The improved batching system allows for simultaneous batching and crucible preparation processes. The mixing platform enables pre-batching, multiple interval mixing, and the addition and covering of the covering agent, thereby significantly shortening the linear length of the sample mixing and melting area and improving production line efficiency.
