Detailed Description

The present invention will be further described with reference to the following examples, which are not intended to limit the scope of the present invention, but are intended to be covered by the appended claims in any way.

Referring to fig. 1-3, the utility model discloses a processing apparatus for gravel and sand recovery in construction waste, including a separator 1. The top of cylinder 1 is equipped with the feeder hopper, and two servo motor 2 are installed to one side of cylinder 1, and pivot 3 is installed to servo motor 2's drive end, and pivot 3 runs through cylinder 1 and extends to the opposite side of cylinder 1, and pivot 3 rotates with cylinder 1 to be connected, is equipped with a plurality of toper material beating poles 4 on the lateral wall of pivot 3. When the construction waste enters the separating cylinder, the construction waste is scattered through the rotating conical knockout rod 4. The construction waste accumulated for a long time is likely to be agglomerated by moisture and its own pressure, and if it is not scattered, it may not be separated completely. The below of separation cylinder 1 is equipped with vibrating screen 5, and vibrating motor 6 is installed to vibrating screen 5's bottom, and vibrating screen 5's discharge end is equipped with stone collection box 7, realizes the recovery of stone. The below of shale shaker 5 is equipped with sand circulation case 8, and shale shaker 5 passes through spring 9 and is connected with sand circulation case 8, and the one end of sand circulation case 8 is equipped with sand recovery case 10, is equipped with dust removal mechanism between sand recovery case 10 and the sand circulation case 8. Through the dust removal effect of the dust removal mechanism, the sand separated from the sand and the stone is removed and then recovered, and the purity of the recovered sand can be effectively improved.

Preferably, the two servo motors 2 rotate in opposite directions to better break up the gravel and sand.

A sand flowing channel 11 which is obliquely arranged is arranged in the sand flowing box 8, a plurality of refining grids 12 are arranged at the discharging end of the sand flowing channel 11, and a sand guide plate 13 is arranged on the outer side of each refining grid 12. Through the blocking and refining functions of the refining grid bars 12, sand can enter the sand guide plate 13 more uniformly, and the subsequent dust removal of the sand is facilitated.

The dust removing mechanism of the present embodiment includes a dust recovery bag and a blower 14. The blower 14 is arranged on one side of the sand recycling tank 10, the other side of the sand recycling tank 10 is provided with a dust collection interface 15, and the dust collection interface 15 is connected with the dust recycling bag through a connecting pipe to realize dust removal of sand. And the dust is recycled through the dust recycling bag, so that the problem that the dust pollutes the surrounding environment can be avoided.

Preferably, an induced draft fan is arranged in the connecting pipe. Through the mode of one blowing and inhaling promptly, can be better lead the dust that blows off, can effectual improvement dust removal effect. The dust collection connector 15 is a horn-shaped connector, which is beneficial to recycling dust.

Preferably, the discharge end of the vibrating screen 5 is hinged with a stone guide plate 16, an electric push rod is hinged below the vibrating screen 5, and the piston end of the electric push rod is hinged below the stone guide plate 16. Through the action of the electric push rod, the stone material guide plate 16 can swing up and down to adjust the position of the stones falling into the stone recovery box 7, so that the stones are more uniformly filled in the stone recovery box 7.

The utility model discloses a theory of operation is: the servo motor 2 is started to add construction waste from the feed hopper to the separation cylinder 1. When the construction waste falls to the position of the rotating shaft 3, the conical material beating rod 4 on the rotating shaft 3 breaks up the construction waste to separate sand and stones. The separated sand and stones enter the vibrating screen 5, the sand falls in the sand flowing box 8 from the meshes of the vibrating screen 5 in a vibrating mode, and the stones fall in the stone recovery box 7 from the discharge end of the vibrating screen 5. The sand dropped in the sand circulation box 8 will automatically flow towards the sand reclamation box 10, and in the process of the sand flowing out of the sand circulation box 8 and dropping in the sand reclamation box 10, the blower 14 blows the dust in the sand towards the dust suction interface 15 to remove dust from the sand, improving the purity of the sand dropping in the sand reclamation box 10.

The above is only the preferred embodiment of the present invention, and it should be noted that for those skilled in the art, without departing from the structure of the present invention, several modifications and improvements can be made, which will not affect the utility model and the utility of the patent.
