And the precipitate is conveyed to the top of the stirring assembly through a spiral blade in the stirring assembly, and is discharged through a slag discharge pipe, so that the problem that wastewater is pretreated by adopting a filter screen at the present stage, and time and labor are consumed when the filter screen is cleaned subsequently is solved.

The utility model belongs to the technical field of gulch gold beneficiation equipment, and particularly relates to an automatic rapid ore discharging and gold beneficiation chute. During normal production, ore pulp flows out of a chute body through an ore discharging opening cover plate, when ore discharging is needed, an ore discharging and flushing switch is turned on, the switch controls thin air cylinders on the two sides to support and connect a lifting plate at the same time, and the thin air cylinders are connected with the lifting plate; when the lifting plate is lifted, the vortex plate ore storage grid connected to the lifting plate and the ore discharge port cover plate are also lifted together, and heavy minerals on the bed surface flow into the ore discharge hopper through the ore discharge port reserved in the lower portion of the pressing plate under the scouring of large water flow of the ore discharge flushing pipe and are finally collected into a recovery container through the ore discharge pipe. The whole ore discharge is automatically completed, the process is automatic, rapid and convenient, and the ore discharge can be completed within 5-10 minutes, so that the ore discharge time is greatly saved, the production time is prolonged, the labor intensity is reduced, and the number of workers is reduced.

This utility model relates to the field of mining blasting technology and provides a dust suppression device after open-pit mine blasting. The device includes a main body with a water tank fixedly installed inside. A water injection pipe is fixedly embedded in the right side of the water tank, and the outer surface of the water injection pipe is fixedly embedded in the rear side of the main body. It also includes a feeding component fixedly embedded inside the main body. In use, the design of the feeding tray and stirring blade structure allows for precise control of the dust suppressant dosage each time, while effectively mixing the dust suppressant and water to ensure a fully uniform distribution. This enhances the adhesion of the sprayed water mist particles, enabling them to adhere more effectively to the surface of fine dust particles, increasing the settling velocity of the dust particles. This improves the settling velocity of fine particles and reduces the likelihood of them being blown away by the wind.
