Description

Technical Field

[0001] This invention relates to the field of concrete material preparation technology, and in particular to a low-carbon and environmentally friendly building concrete material preparation device and preparation method. Background Technology

[0002] Low-carbon and environmentally friendly building concrete materials refer to concrete materials that can significantly reduce carbon emissions and environmental impact during production, use, and disposal. These materials not only help reduce the consumption of natural resources but also improve the sustainability and environmental performance of buildings. They reduce carbon emissions and environmental impact during production, while utilizing industrial waste and recycled materials to reduce dependence on natural resources and improve the durability and service life of concrete, reducing the frequency of maintenance and replacement. Therefore, a preparation device is needed to facilitate the processing of building concrete materials.

[0003] However, in the current traditional concrete material preparation equipment, the recycled aggregate usually needs to be cleaned during the preparation process. During the cleaning process, the surface dust is mostly treated by drum cleaning. However, since the recycled aggregate is mixed with small particles during the crushing process, it does not meet the preparation requirements. As a result, recycled aggregate of different volumes is mixed and cleaned during the cleaning process, which is not convenient for subsequent preparation. Summary of the Invention

[0004] This disclosure relates to a low-carbon and environmentally friendly building concrete material preparation device and method, which includes an external discharge section and a cleaning section. Aggregates are conveyed to the inside of a cleaning drum through a diversion cylinder. The cleaning drum is then rotated and adjusted by a torsion motor and a cylindrical gear, which simultaneously causes the internal aggregates to tumble, cooperating with the liquid inside the loading cylinder to clean the aggregates. During the cleaning process, internal particulate matter is screened out and falls into the inside of a pull-out drawer. Impurities on the surface of the aggregates float to the liquid surface due to buoyancy, thus completing the cleaning of the aggregates. A dust baffle is flipped up and slides and closes inside the loading cylinder, thereby separating the internal liquid. Then, a blocking rod is pulled out from the drain hole, allowing the internal liquid to be discharged from the drain hole. Then, by rotating a locking torsion ring, the external discharge drawer slides inside the cleaning drum, discharging the cleaned aggregates from the cleaning drum during the sliding process. At the same time, the pull-out drawer is pulled out from the bottom solidification tank to collect the screened small particulate matter.

[0043] In the embodiments disclosed herein, such as Figure 11As shown, the cleaning drum 301 is a cylindrical structure with equidistant lower drainage holes on its outer wall.

[0044] This invention discloses a method for preparing a low-carbon and environmentally friendly building concrete material preparation device, comprising the following steps:

[0045] 1. When cleaning recycled aggregate, the aggregate is conveyed to the inside of the cleaning drum 301 through the diversion cylinder 102. Then, the cleaning drum 301 is rotated and adjusted by the torsion motor and the column gear. At the same time, the aggregate inside is turned over to cooperate with the liquid inside the loading cylinder 101 to clean the aggregate. During the cleaning process, the internal particulate matter is screened out and falls into the inside of the pull-out drawer 202. Meanwhile, the impurities on the surface of the aggregate float to the surface of the liquid due to buoyancy, so as to complete the cleaning of the aggregate.

[0046] 2. During the external discharge process, the dust baffle 304 is flipped up to slide and close inside the loading cylinder 101, thereby separating the internal liquid. Then, the blocking rod 204 is pulled out from the drain hole 203, allowing the internal liquid to be discharged from the drain hole 203. Then, by rotating the locking torsion ring 303, the external discharge puller 302 is driven to slide inside the washing drum 301. During the sliding process, the washed aggregate is discharged from the washing drum 301. At the same time, the pull-out drawer 202 is pulled out from the bottom solidification tank 201 to collect the screened small particles.

[0047] The specific usage and function of this embodiment: In this invention, when in use, the entire device is moved to a designated position, and then liquid is added to the inside of the loading cylinder 101. Then, the recycled aggregate to be cleaned is transported to the inside of the loading cylinder 101 and the cleaning drum 301 through the diversion cylinder 102, so that the recycled aggregate is immersed in the liquid. Then, the torsion motor on the loading cylinder 101 is started, which drives the column gear to control the cleaning drum 301 to rotate. This facilitates the internal recycled aggregate to be turned over during the rotation. During the turning process, the recycled aggregate is cleaned by the liquid. At the same time, during the cleaning process, the small particle impurities mixed in the recycled aggregate are screened out by the rolling and fall into the pull-out drawer 202 for temporary storage. The dust on the surface of the recycled aggregate is mixed in the liquid under the cleaning of the liquid and floats on the surface of the liquid, so as to facilitate the cleaning of the recycled aggregate.

[0048] After cleaning, the dust baffle 304 is flipped up and slidably adjusted within the guide groove 103. After moving to the designated position, the locking frame 205 is rotated to lock the dust baffle 304 with the nut, thereby dividing the internal space of the loading cylinder 101. Then, the blocking rod 204 is pulled out to allow the liquid inside the loading cylinder 101 to drain out through the drain hole 203. After the liquid is drained, the external pull-out drawer 202 is used to pull out the accumulated small particles inside for easy collection. Then, the locking torsion ring 303 is rotated to pull out the external puller 302, which helps to push the cleaned recycled aggregate outward, facilitating the collection and discharge of the cleaned recycled aggregate for later concrete material preparation.
