Apparatus for Recovering Gravels and Sands from Waste Ready-Mixed Concrete

摘要

The present invention provides in particular for the gravel and sand and the water separation, but to effectively improve the workability and to minimize the floor space the other hand, high-quality recycled aggregate by reducing the water content of the screened aggregate recycling apparatus of waste ready-mixed concrete.; The invention lungs ready-mixed concrete is sent (10), pump (P) and the secondary sludge tank 40 of the selected gravel and the conveyor (20) (21), and primary sludge tank (30) for conveying the sand a spring for each of the pipes 31, 41 as in the cyclone 50 and the conventional structure of the connection, the closed ready-mixed concrete sent 10 and the conveyor 20, 21 has a bottom fixed plate between 61 ( in the S) by the interlocking configuration of the vibration housing (60) which vibrates at a vibration motor (M) of the upper oscillating housing 60 has a screen net body 62 and a screen net body 63 of the micro pores of the upstream inclined pores the up and down to be performed in hangong determine the gravel and sand at the same time by installing the other hand, each screen net body is vibrated in the upward diagonal direction by the vibration of the vibration housing and increase the dewatering effect with a feed want of gravel and sand, the conveyor 20, 21 is full, by one end, while the net body, each screen 62, 63, a terminal position on the bottom up and down configuration To thereby greatly reducing the installation area. In addition, to the pump (P) up or stop according to the first the inner wall of the sludge tank 30, at the bottom of the pump (P) and electrically-level switch (SW1) water level a (SW2) by configuring the inflow linked to .
