Concrete powder storage tank for environment-friendly concrete production

The utility model discloses a concrete powder storage tank for environment-friendly concrete production, and relates to the technical field of environment-friendly concrete. The device comprises a first storage box used for storing concrete powder needed in the concrete production process; the second storage box is used for storing concrete powder with the particle diameter exceeding the standard; a screening mechanism used for screening concrete powder is installed in the first storage box. A discharging pipe is fixed to the bottom of the first storage box, and a smashing mechanism used for smashing concrete in the caking state is installed in the discharging pipe. By means of the screening mechanism, concrete powder which does not meet the standard can enter the second storage box, the quality of subsequent concrete is improved, the situation that the concrete powder which does not meet the standard enters the subsequent machining process is reduced, the caking phenomenon of the concrete powder can be reduc
