Technical Field

[0001] This utility model relates to the field of screening technology for purified ash from calcium carbide furnaces, specifically a screening device for secondary production of purified ash from calcium carbide furnaces. Background Technology

[0002] Purification ash is an industrial waste residue generated during the industrial production of acetylene, polyvinyl chloride, etc. Its main component is calcium hydroxide, and it also contains small amounts of oxides such as silicon dioxide, aluminum oxide, and iron oxide, as well as a small amount of organic matter. The strong alkalinity and high calcium content of purification ash make it a potential raw material for desulfurization agents. This allows purification ash to be processed into desulfurization raw materials, thereby reducing environmental pollution and enabling effective recycling of purification ash.

[0003] Purification ash is a type of solid waste, which is generally disposed of by stockpiling or landfilling. However, these methods cause significant environmental pollution and the ash cannot be effectively recycled. Therefore, a recycling system for purification ash is needed to effectively recycle and reuse the ash and reduce environmental pollution. Utility Model Content

The two ends of screening plate 7 and screening plate 8 are respectively located in the guide groove 15 at the corresponding positions and are slidably connected.

[0027] In this embodiment of the utility model, by opening the electric push rod 502 and hydraulic rod 503 inside the power box 501, and cooperating with the connecting plate 1 504 and the connecting plate 2 505, the screening plate 1 7 and the screening plate 2 8 can be driven to reciprocate in opposite directions, ensuring the screening efficiency of the purified ash mixture.

[0028] Please refer to Figures 2-4 The vibrating material throwing mechanism 4 includes an installation groove 401 opened in the inner wall of the machine body 2.
