Description

Technical Field

[0001] The utility model relates to the technical field of concrete, in particular to a cleaning mechanism for processing recycled concrete aggregate. Background Art

[0002] Recycled concrete often contains impurities such as dirt, sawdust, and plastic. While crushing equipment can remove some impurities to a certain extent, complete removal is often difficult. Residual impurities can affect the quality of the recycled aggregate and reduce the performance of the recycled concrete. For example, the presence of dirt can affect the bonding between the recycled aggregate and cement, reducing the strength of the concrete; impurities such as plastic can create weak spots in the concrete, affecting its durability. Therefore, thorough cleaning of the concrete aggregate is crucial:

[0003] First, cleaning concrete aggregate enhances its strength and durability. The clean surface of the cleaned aggregate strengthens its bond with the cement paste, forming a tighter bond during the hardening process, thereby increasing its strength. Clean aggregate also reduces pores and cracks in the concrete, reducing the penetration of moisture and harmful substances, and enhancing its durability.

[0004] Secondly, cleaning concrete aggregates can reduce the risk of alkali-aggregate reaction. Uncleaned aggregates may contain reactive minerals that react with the alkali in cement, producing expansive substances that can cause cracking and damage to the concrete. Aggregate cleaning removes these reactive substances, ensuring project safety.

[0005] At the same time, unwashed aggregates will generate a lot of dust during transportation, stacking and use, causing environmental pollution. Therefore, the cleaning process is very necessary.

[0006] However, the current cleaning device cannot fully clean the aggregate, has a slow cleaning speed and low efficiency, cannot tumble the aggregate, and the dirt on the aggregate is not easy to fall off, resulting in poor cleaning effect.

[0007] In order to solve this technical problem, we propose a cleaning mechanism for processing recycled concrete aggregate. Utility Model Content

[0008] The purpose of the utility model is to provide a cleaning mechanism for processing recycled concrete aggregate to solve the problems raised in the above background technology.

[0009] In order to solve the above technical problems, the utility model provides the following technical solutions: a cleaning mechanism for recycled concrete aggregate processing, comprising a main structure and a circulation structure, wherein the outer wall of the main structure is fixedly connected to the circulation structure;

[0010] The main structure includes a cleaning box, a high-pressure spray head is fixedly connected to the top wall of the cleaning box, a driving motor is fixedly connected to the outer wall of the cleaning box, an output end of the driving motor is fixedly connected to a driving gear, an outer surface of the driving gear is meshed with a driven gear, an outer wall of the driven gear is fixedly connected to a rotating shaft, an end of the rotating shaft away from the driven gear is fixedly connected to a cleaning cylinder, a friction block is fixedly connected to the inside of the cleaning cylinder, and an end of the cleaning cylinder away from the rotating shaft is fixedly connected to a feed hopper.

[0011] Preferably, one end of the rotating shaft away from the driven gear passes through the cleaning box and extends to the inside, and the rotating shaft is rotatably connected to the cleaning box via a bearing.

[0012] Preferably, one end of the feed hopper away from the cleaning cylinder passes through the inner wall of the cleaning box and extends to the outside, and the feed hopper is rotatably connected to the cleaning box through a bearing.

[0013] Preferably, the circulation structure includes a purification box body, a filter assembly is provided inside the purification box body, the outer wall of the purification box body is fixedly connected to a first water tank, the inner bottom wall of the first water tank is fixedly connected to a first water pump, the output end of the first water pump is fixedly connected to a water pipe, a second water tank is provided at the end of the water pipe away from the first water pump, the inner bottom wall of the second water tank is fixedly connected to a second water pump, and the output end of the second water pump is fixedly connected to a water inlet pipe.

[0014] Preferably, a drain pipe is fixedly connected to an outer wall of the purification box body on one side close to the first water tank, and the drain pipe is arranged in the first water tank.

[0015] Preferably, one end of the water inlet pipe away from the second water pump passes through the top of the cleaning box and extends to the inside of the cleaning box to be fixedly connected to the high-pressure sprinkler head.

[0016] Preferably, a water injection pipe is provided on the top of the second water tank.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0018] First, the utility model puts aggregate into the cleaning barrel through the feed hopper, injects clean water into the second water tank through the water injection pipe, starts the second water pump to pass the clean water through the water inlet pipe and the high-pressure spray head, and uses the impact force of water to efficiently clean the aggregate. By starting the drive motor, the driving gear is driven to rotate, and the driving gear drives the meshing driven gear to rotate. The rotating driven gear drives the rotating shaft to rotate, and also drives the cleaning barrel to rotate, so that the high-pressure spray head can fully clean the aggregate from multiple angles. The aggregate rolls in the cleaning barrel, and the aggregate collides and rubs against the friction block, which causes the dust and dirt on the aggregate to fall off. The combination of the two cleaning methods further improves the cleaning effect, can continuously clean the aggregate, and has a fast cleaning speed and high efficiency.

[0019] Secondly, the sewage after cleaning the aggregate flows into the purification box, and is filtered and purified by the filtering component. The filtered water is discharged into the first water tank through the drain pipe, and the first water pump is started to input the filtered water into the second water tank through the water pipe, and then the second water pump is started to input the filtered water into the high-pressure sprinkler head through the water inlet pipe to complete the water cycle, and finally achieve the purpose of recycling water resources, reducing resource consumption rate and reducing use cost.
