AI Technical Summary

⚠Technical Problem

In existing technologies, the calcium carbonate generated from gypsum dust produced during gypsum mine crushing tends to accumulate at the bottom of the equipment after dust suppression treatment, leading to secondary pollution that is difficult to clean.

⚗Method used

A dust recycling device for gypsum production was designed, which includes a spraying device, a collection device, a splash prevention device, and a tapping device inside the dust suction pipe. Through spraying, compaction, splash prevention, and vibration, the effective collection and cleaning of calcium carbonate is achieved.

🎯Benefits of technology

It effectively prevents calcium carbonate residue at the bottom of the suction pipe, reduces secondary pollution, and improves the efficiency of dust recovery and cleaning effect.

Abstract

The application discloses a dust recycling equipment for gypsum production and relates to the technical field of gypsum, which comprises a dust suction pipe, a spray washing device arranged in the dust suction pipe, a linear motor, a sliding rod fixedly installed at the output end of the linear motor, a top rod, a rotating nozzle, a pull rod and a blowdown cover plate. The outer wall of the sliding rod is rotatably installed at one end of the top rod, the other end of the top rod is rotatably installed on the outer wall of the rotating nozzle, the outer wall of the lower end of the sliding rod is rotatably installed at one end of the pull rod, the other end of the pull rod is rotatably installed on the outer wall of the blowdown cover plate, a blowdown opening is arranged in the bottom of the dust suction pipe, and the blowdown cover plate is slidably installed in the blowdown opening. The dust recycling equipment for gypsum production is provided with the spray washing device. When the sliding rod moves downward, the rotating nozzle can spray downward, and the blowdown opening is opened through the pull rod, so that the spraying of the rotating nozzle can spray calcium carbonate at the bottom into the collecting box for collection, thereby preventing secondary pollution caused by the residual calcium carbonate at the bottom of the dust suction pipe.
