Embodiment 1

[0030] Embodiment 1 is basically as attached figure 1 As shown: a device for preparing recycled building materials from construction waste, including a shell 1, a feed hopper 23 is welded on the upper part of the shell 1, and a vertical feed channel 24 is welded on the top wall of the shell 1, and The feed channel 24 is located inside the housing 1 . The casing 1 is provided with a screening mechanism capable of simultaneously screening aggregates of different particle sizes, and an adjustable proportioning mechanism is provided below the screening mechanism, and the adjustable proportioning mechanism is connected to a mixing box 18 .

[0031] The screening mechanism is used to screen the crushed construction waste, and screen the crushed construction waste into fine aggregate and coarse aggregate. The screening mechanism includes a sieve plate 6, the left end of the sieve plate 6 is set as a fine screen 9, the right end of the sieve plate 6 is set as a coarse screen 8, the t...

Embodiment 2

[0041] combine figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the adjustment assembly in this embodiment includes a first telescopic plate 13 fixed on the bottom of the coarse aggregate box 2 / fine aggregate box 3, and the first telescopic plate 13 When stretched, the outlet 11 can be blocked; the upper part of the coarse aggregate box 2 / fine aggregate box 3 is fixedly connected with a second telescopic plate 14, and when the second telescopic plate 14 is stretched, the discharge path of the aggregate can be staged. . The outer wall of the coarse aggregate box 2 / fine aggregate box 3 is fixedly connected with a load cell, the left side wall of the coarse aggregate box 2 / fine aggregate box 3 is provided with a strip hole, and one end of the first telescopic plate 13 is passed through The strip-shaped hole is fixedly connected with the load cell, and the load cell is connected with a controller 15 for controlling the expansion and contraction ...

Abstract

The invention relates to the field of construction waste disposal, and more particularly discloses a plant for preparing recycled construction materials from construction waste. The plant comprises ahousing in which a screening mechanism that can realize simultaneous screening of aggregates with different particle sizes. The screening mechanism comprises a fine aggregate section and a coarse aggregate section. An adjustable proportioning mechanism is disposed below the screening mechanism. The adjustable proportioning mechanism comprises a coarse aggregate box and a fine aggregate that directly face the coarse aggregate section and the fine aggregate section, respectively. An adjusting module for adjusting a feeding amount is disposed in each of the coarse aggregate box and the fine aggregate box. The plant for preparing recycled construction materials from construction waste solves the problem of high working strength of an operator due to manual proportioning and mixing of differentaggregates as required for construction materials to be prepared during aggregate proportioning in prior art.

Description

technical field [0001] The invention relates to the field of construction waste treatment, in particular to a device for preparing recycled building materials from construction waste. Background technique [0002] As one of the pillar industries of the national economy, the construction industry has developed rapidly in recent years. With the gradual acceleration of the pace of urbanization in my country, the total amount of urban construction waste is increasing year by year. Most of the construction waste from the demolition of old buildings in our country is used as road foundation cushion and site backfill, and most of them are discharged as garbage. Even if they are used to fill lakes and ponds, they also cause new environmental hazards. For this reason, recycling construction waste to prepare recycled aggregate has become a research hotspot in recent years. The use of construction waste to prepare recycled aggregate can not only solve the problem of waste of land res...
