Problems solved by technology

The utility model waste concrete has a strong source property, no special treatment is required, less and more precise equipment and low energy consumption can realize the joint production of various recycled materials; the strength of C30 concrete mixed with recycled sand is higher than that of the reference concrete, and the recycled sand has no impact on slump Concrete with higher slump requirements has better adaptability, and the best replacement rate of recycled sand is 10% to 30%; the disadvantage of this utility model is that waste concrete cannot be completely crushed and cannot be screened and classified

Abstract

The invention relates to a device for preparing reclaimed sand, in particular to a device for preparing reclaimed sand through waste concrete. The device for preparing reclaimed sand through waste concrete comprises a side support I, a side support II, a power mechanism, a planetary gear mechanism, a gear ring, a crushing cylinder, a sieve plate, a transmission mechanism I, a pushing mechanism, acrushing mechanism, a transmission mechanism II, a crank mechanism, connecting rods and a sieve box. The planetary gear mechanism comprises a supporting plate, a supporting cylinder, a planetary gearbase plate, a sliding column, two rotary columns and planetary gears, wherein the supporting cylinder is fixedly connected to the supporting plate, the planetary gear base plate is fixedly connected to the inner circle of the supporting cylinder, the lower end of the sliding column is fixedly connected to the planetary gear base plate, the upper ends of the two rotary columns are fixedly connectedto the planetary gear base plate, and the planetary gears are rotatably connected to the two rotary columns. Concrete can be completely crushed in two directions through the crushing cylinder and thecrushing mechanism, and the completely-crushed concrete is screened through the sieve box.

Description

technical field [0001] The invention relates to a device for preparing recycled sand, more specifically, a device for preparing recycled sand from waste concrete. Background technique [0002] For example, patent number CN201620077756.0 is a system device for preparing recycled sand from waste concrete, including a feeding hopper, a belt input machine, a fine crusher, a belt output machine, and a screening machine arranged in sequence, so as to realize recycled sand, recycled gravel, and recycled melon. Combined production of rice stone and regenerated fine powder; also includes a dust collector equipped with induced draft fan and air compressor for collecting the dust from the fine crusher and the sieving machine to produce regenerated fine powder. The utility model waste concrete has a strong source property, no special treatment is required, less and more precise equipment and low energy consumption can realize the joint production of various recycled materials; the stren...
