The utility model discloses a molding sand preparation device and relates to the technical field of molding sand preparation. The device comprises a preparation tank, a tank cover is detachably mounted at the upper end of the preparation tank, a connecting structure is arranged between the preparation tank and the tank cover, a rotating pipe is movably inserted into the upper end of the tank cover, the lower end of the rotating pipe is movably inserted into the preparation tank, and stirring rods are arranged on the two sides of the rotating pipe. A driver is fixedly mounted at the upper end of the tank cover, a transmission gear is mounted at the output end of the driver, a user puts materials into the preparation tank, the driver drives a rotating pipe to rotate through the transmission gear and a rotating gear, the rotating pipe conveniently mixes and stirs the materials in the preparation tank through a stirring rod, and the stirring rod is used for stirring the materials in the preparation tank. And water enters a rotating pipe through a connecting water pipe and is sprayed out through water spraying holes in the surfaces of the rotating pipe and a rotating water pipe, so that the materials in the preparation tank are conveniently and comprehensively sprayed, and the mixing effect is enhanced.

This invention discloses a waste circuit board processing system and method, belonging to the field of waste circuit boards. The waste circuit board processing system includes a crushing device, a dehydration device, a mixer, a microwave pyrolysis furnace, a heat exchanger, an absorption tower, an adsorption system, an incineration system, and a chimney, arranged sequentially along the processing direction. The desorption gas outlet of the adsorption system is connected to the incineration system via a pipeline, and the exhaust port of the adsorption system is connected to the chimney via a pipeline. The exhaust port of the incineration system is connected to both the chimney and the adsorption system via pipelines. This invention employs a microwave high-temperature pyrolysis + oxide absorption process to separate the circuit board metal from the substrate, effectively reducing the generation of gases such as dioxins.
