The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

As shown in fig. 1-3:

a building waste powder recovery system for manufacturing waste bricks comprises a cyclone separator 1, a fine material storage tank 2, a coarse material storage tank 3 and a spraying settling tank 4, wherein a filtering assembly 5 is arranged at an outlet of a blanking pipe 31 at the top of the coarse material storage tank 3 and is connected with an air inlet pipe 11 of the cyclone separator 1 in the vertical direction; the blanking pipe 31 is connected with the exhaust pipe 6 of the dust suction device in a T shape; the outlet at the bottom end of the cyclone separator 1 is connected with the fine material storage tank 2, and the exhaust pipe 12 at the top is connected with the buffer water tank 43.

The working process is as follows: the dust collector of the factory area sucks the raised dust formed in the process of crushing the building waste powder and leaves the raised dust to the blanking pipe 31 from the exhaust pipe 6 of the dust collector, as the outlet of the blanking pipe 31 is provided with the filtering component 5, larger particles are intercepted, and the building waste particles enter the coarse material storage tank 3 through the blanking pipe 31 under the action of gravity because of too large specific gravity, the filtered air flow continuously enters the cyclone separator 1 to separate fine dust and then enters the fine material storage tank 2 (the cyclone separator is based on the cyclone separation technology, and the separation between phases is realized by utilizing the density difference between two phases or multiple phases under the action of centrifugal force, which is a separation device rapidly developed in recent years and is not repeated because of the prior art, the dust content in the separated air flow is very low, but in order to reduce pollution, the discharged air flow is sprayed and settled through the spraying and settling tank 4, the treated gas stream is almost dust free.

Specifically, the filter assembly 5 comprises a filter cavity 51 and reverse threaded connectors 52 at two ends, and a filter screen 53 is installed in the filter cavity 51, so that the filter assembly can be conveniently detached to be replaced or the filter screen can be conveniently cleaned.

Specifically, the filter screen 53 is made of a stainless steel wire mesh, and the filtering aperture is 0.8-1.2mm, because the construction waste powder is high in hardness and is in a high-speed movement state, the filter screen needs to have certain strength to avoid frequent replacement.

Specifically, the spray settling tank 4 comprises a tank body 41 and a buffer tank 43, wherein one side of the tank body 41 is connected with the exhaust pipe 12 of the cyclone separator 1, the top of the other side is provided with an exhaust port 42, and the bottom side is provided with a sewage discharge pipe 47; the top of the box body 41 is externally provided with the buffer water tank 43, the bottom of the buffer water tank 43 is transversely provided with a plurality of flat water outlet seams 43a at intervals, and compared with a spray head mode, the flat water outlet seams 43a form a water curtain, so that the sedimentation effect is better.
