Description

Technical Field

[0001] The present application relates to the technical field of aggregate recovery devices, and in particular to an aggregate recovery device. Background Art

[0002] Aggregate, also known as "aggregate", is a granular material that acts as a skeleton and filler in concrete and mortar. There are two types: fine aggregate and coarse aggregate. The diameter of fine aggregate particles is between 0.16 and 5 mm. Natural sand is generally used, such as river sand, sea sand and valley sand. When natural sand is lacking, artificial sand ground from hard rocks can also be used. The diameter of coarse aggregate particles is greater than 5 mm. Commonly used ones are crushed stone and pebbles. Under the same conditions, the strength of crushed stone concrete is higher than that of pebble concrete, but crushed stone is made by crushing rocks, and its cost is higher than that of pebbles. The coarse aggregates commonly used in lightweight aggregate concrete include natural porous rocks such as pumice, and artificial porous aggregates such as ceramsite and expanded slag.

[0003] During the concrete production process, an inclined belt conveyor is required to transport the aggregates in the aggregate silo to the mixing equipment. During the conveying process, the belt needs to be sprayed with water to clean it. However, there is no device in the existing aggregate recovery device that can realize integrated recovery technology.

[0004] For this purpose, the present application proposes an aggregate recovery device. Utility Model Content

[0005] The present application proposes an aggregate recovery device to solve the problems raised in the above-mentioned background technology. By arranging a conveying mechanism, a feeding mechanism, a settling mechanism, a discharging mechanism, a discharging mechanism and a recovery mechanism, spray water containing aggregate enters the connecting pipe through the conveyor, and the aggregate passing through the connecting pipe falls into the sedimentation tank and is deposited in the sedimentation area. The left side wall of the sedimentation tank is connected to an overflow pipe for recovering clean water. By arranging a bucket shape below the sedimentation area, the aggregate in the sedimentation area is discharged smoothly. By opening the valve, the deposited aggregate is discharged from the sedimentation area in the sedimentation tank into the discharge pipe, and falls into the guide chute through the discharge pipe. By arranging an inclined plate in the guide chute, the aggregate in the guide chute is facilitated to enter the recovery pool smoothly. By arranging a recovery mechanism, the aggregate falling into the guide chute from the discharge pipe is recovered and uniformly recovered into the recovery pool, realizing integrated aggregate recovery, saving time cost and labor cost, greatly improving the efficiency of aggregate recovery, and further enhancing the practicality of the device.

After the aggregate passes through the connecting pipe 31 and falls into the sedimentation tank 42, it is deposited in the sedimentation area 44. The left side wall of the sedimentation tank 42 is connected with an overflow pipe 47 for recovering clean water. By setting a bucket shape 45 below the sedimentation area 44, the aggregate in the sedimentation area 44 is discharged smoothly. By opening the valve 52, the deposited aggregate is discharged from the sedimentation area 44 in the sedimentation tank 42 into the discharge pipe 51, and falls into the guide trough 62 through the discharge pipe 51. By setting an inclined plate 63 in the guide trough 62, the aggregate in the guide trough 62 is facilitated to smoothly enter the recovery tank 72. By setting the recovery mechanism 7, the aggregate falling into the guide trough 62 from the discharge pipe 51 is recovered and uniformly recovered into the recovery tank 72.
