Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of impurity removal, in particular to an impurity removal device for high-strength and durable recycled concrete. Background Art
[0002] High-strength concrete refers to concrete with a strength grade of C60 or above. Aggregate is a granular loose material that acts as a skeleton or filler in concrete. Aggregate prepared by crushing and screening waste concrete is called recycled concrete aggregate (recycled aggregate for short). When recycled aggregate is used in high-strength concrete, it needs to be screened before use.
[0003] At present, with the rapid development of cities, more and more waste concrete is generated. In order to reuse the waste concrete and prevent the waste concrete from polluting the environment, people crush and remove impurities from the waste concrete to generate recycled concrete aggregate. The impurity removal device under the existing technology has relatively complete functions, but it is impossible to effectively remove the leaves and plastic products mixed in the waste concrete, resulting in leaves and plastic products mixed in the waste concrete, causing quality problems of the recycled concrete. At the same time, the screening of coarse aggregate and fine aggregate requires the screening of the waste concrete after impurity removal, resulting in the mixing of qualified and unqualified aggregates during screening, which can easily lead to blockage of holes, resulting in slow screening and low screening efficiency.

[0010] Compared with the prior art, the utility model has the following beneficial effects:
[0011] 1. The impurity removal device for high-strength and durable recycled concrete can remove light debris such as leaves in waste concrete through structures such as a mixing box, an overflow port, and a water tank. The water bucket continuously fills the mixing box with water through a transmission pipe and a diversion pipe. When the waste concrete enters the mixing box, the light debris mixed in the waste concrete floats on the water surface due to the stirring of the motor A. When the water inside the mixing box reaches a certain amount, it flows back into the water tank through the overflow port, and the light debris floating on the water surface will follow the water flow into the water tank, and the light debris such as leaves will be removed after being filtered by a filter plate, thereby achieving the effect of removing light debris such as leaves mixed in the waste concrete.
[0012] 2. The impurity removal device of the high-strength and durable recycled concrete realizes the repeated use of filtered water by setting up overflow ports, water tanks, diversion pipes and other structures. The waste liquid in the mixing box flows back to the water tank, and the built-in pump in the water tank pumps the waste liquid into the cyclone. Through the separation effect of the cyclone, the sand and dust particles in the waste liquid flow out through the aggregate outlet, and the filtered water filtered by the cyclone flows out through the water source outlet and enters the interior of the mixing box through the transmission pipe and the diversion pipe.
[0013] 3. The impurity removal device of the high-strength and durable recycled concrete can distinguish the coarse and fine aggregates of the waste concrete by setting structures such as a discharge box, a cyclone, and an aggregate trough. The waste concrete is stirred by a mixing box, and the fine aggregate and light garbage enter the water tank with the water flow. After being separated by the cyclone, the fine aggregate is discharged from the aggregate outlet of the cyclone. The coarse aggregate is heavier and sinks in the mixing box. It is sent into the discharge box by a spiral blade, and the coarse aggregate is discharged by the discharge box, which has the effect of separating the coarse and fine aggregates.

[0023] A tripod is fixedly installed on the top of the water tank 11, and a cyclone 14 is fixedly installed on the inner ring of the tripod. A wastewater pipe 15 is fixedly connected between the water tank 11 and the cyclone 14. A water pump is built in the water tank 11 to pump the wastewater in the water tank 11 into the cyclone 14 through the wastewater pipe 15. The bottom of the cyclone 14 is provided with an aggregate outlet, and the top of the cyclone 14 is provided with a water source outlet. After the water tank 11 pumps the wastewater into the cyclone 14, the sand and small particles in the wastewater are separated by the cyclone 14.

[0024] Working principle: The crushed waste concrete is poured into the mixing box 1 through the feed port of the mixing box 1, and the water tank 11 continuously flows into the mixing box 1 through the diverter pipe 18. The motor A6 stirs the waste concrete through the spiral blade 10, so that the leaves and plastic products mixed in the waste concrete float on the water surface. After the water fills the mixing box 1, it flows into the water tank 11 through the overflow port 5, and the leaves and other debris floating on the water surface follow the water flow into the water tank 11. After entering the water tank 11, it is filtered by the filter plate 13. The leaves and other debris are isolated above the filter plate 13 and mixed with the ash. Wastewater containing dust and sand and gravel flows into the water tank 11, and is pumped into the cyclone 14 by the built-in pump of the water tank 11. After separation in the cyclone 14, aggregates such as sand and gravel flow out through the bottom aggregate outlet, and the filtered water flows into the transmission pipe 17 and the diversion pipe 18 through the upper water source outlet. The filtered water flows into the interior of the mixing box 1 through the transmission pipe 17 and the diversion pipe 18, thereby realizing the recycling of water. The waste concrete without debris follows the rotation of the motor A6 and enters the discharge box 7. The motor B9 drives the spiral blade 10 to rotate, and brings the cleaned coarse aggregate out of the discharge box 7, thereby realizing the removal of impurities from the waste concrete.
