Abstract
Description
Technical Field

[0002] Recycled aggregate refers to small-particle aggregate formed after screening and processing of miscellaneous fill, which can be used to make recycled concrete. Recycled aggregate is divided into fully recycled aggregate, recycled coarse aggregate and recycled fine aggregate. During the production and processing of recycled aggregate, impurity removal equipment is often required to clean the impurities in the recycled aggregate to improve the quality of recycled aggregate production;
[0003] After investigation, the disclosure (announcement) number: CN220092054U discloses a recycled aggregate impurity removal device. This technology discloses "a recycled aggregate impurity removal device, including a processing box and a protective door, a impurity removal box is installed above the processing box, and a top cover is provided above the impurity removal box, a rotating rod is connected in the middle of the top cover, and a stirring blade is installed on the outer side of the rotating rod, a blower is provided on the left side of the processing box, and a mounting bolt is connected to the outer side of the blower, an air supply pipe is connected on the left side of the blower, and an air blowing head is provided below the air supply pipe, the protective door is provided on the front outer side of the processing box, and a connecting shaft is provided on the right side of the protective door, a first filter plate is connected to the middle part of the inner side of the processing box, and a collecting box is provided in the middle part of the bottom plate" and other technical solutions, which have "the impurity removal device is convenient and sufficient to remove impurities in the recycled aggregate when in use, thereby obtaining relatively pure aggregate, convenient and automatic classification of the aggregate after impurity removal, convenient fixing of the unloading box position for unloading" and other technical effects;
[0004] Although the above solution already includes the screening and processing steps of recycled aggregates, it is worth noting that the recycled aggregates may still be mixed with metal impurities such as iron filings. The presence of these metal impurities such as iron filings cannot be ignored because they will directly have a negative impact on the quality of the recycled aggregates. These metal impurities may weaken the strength, durability and stability of the aggregates, and thus cause adverse consequences in the application of key areas such as construction and roads, limiting their potential performance and benefits.

[0027] The main assembly 21 includes a bracket 211 fixed on the top of the base frame 1 and an axle seat 212 fixed at both ends of the top of the bracket 211;
[0028] The screening assembly 22 includes a shaft 221 rotatably mounted between shaft seats 212 at both ends, and a frame 222 fixed to the outer wall of the shaft 221;
[0029] The impurity removal assembly 23 includes four lower material bins 231 fixed inside the bracket 211, a conductive magnetic plate 232 rotatably mounted at the lower end of the lower material bin 231, a circular plate 233 fixed at the front end of the conductive magnetic plate 232, and a connecting rod 234 rotatably mounted between each circular plate 233. A servo motor 235 is installed at the rear end of one of the lower material bins 231, and the output end of the servo motor 235 is connected to one of the conductive magnetic plates 232.
[0030] The driving assembly 24 includes a three-phase motor 241 installed on one side of the upper end of the base frame 1.
[0031] In this embodiment, after the screened recycled aggregate falls into the discharge bin 231, the conductive magnetic plate 232 is energized to adsorb metal impurities in the recycled aggregate; when the upward side of the conductive magnetic plate 232 is fully adsorbed, the output end of the servo motor 235 drives the conductive magnetic plate 232 to drive the circular plate 233 to rotate 180°, and the circular plate 233 drives the remaining circular plates 233 to rotate through the connecting rod 234, and the remaining circular plates 233 then drive the remaining conductive magnetic plates 232 to rotate synchronously, so that the other side of the conductive magnetic plate 232 faces upward and continues to adsorb metal impurities; and during the rotation of the conductive magnetic plate 232, the recycled aggregate accumulated in the discharge bin 231 is also removed and can fall into the corresponding collection box 3 below.
[0032] Specifically, the screening assembly 22 further includes a primary filter cartridge 223 , a secondary filter cartridge 224 , a tertiary filter cartridge 225 and a quaternary filter cartridge 226 which are sequentially arranged from left to right inside the frame 222 .
[0033] In this embodiment, the recycled aggregate entering the frame 222 can be screened and processed by the primary filter cartridge 223, the secondary filter cartridge 224, the tertiary filter cartridge 225 and the quaternary filter cartridge 226 in sequence.
[0034] Specifically, the main assembly 21 further includes mounting frames 213 fixed at both ends of the bracket 211 , and a feed hopper 214 and a discharge hopper 215 are respectively fixed on the mounting frames 213 at both ends.
[0035] Specifically, the driving assembly 24 further includes a driven pulley 244 mounted on one end of the shaft 221 , a driving pulley 242 mounted on the output end of the three-phase motor 241 , and a belt 243 mounted between the driving pulley 242 and the driven pulley 244 .

[0037] Specifically, the impurity removal component 23 further includes an arc-shaped groove 236 opened at the upper end of the lower bin 231 .
[0038] In this embodiment, the lower hopper 231 can be matched with the lower end of the frame 222 through the arc-shaped groove 236, so that the recycled aggregate in the screening process can fall into the corresponding lower hopper 231 below.
[0039] Specifically, four collection boxes 3 are placed on the top of the base frame 1, and a limit frame 4 is fixed to the top right end of the base frame 1. The support legs at both ends of the base frame 1 are at different heights, so that the base frame 1 is tilted, with the first-stage filter cartridge 223 located at a higher end and the fourth-stage filter cartridge 226 located at a lower end. The limit frame 4 is located at the lower end.
[0040] In this embodiment, the recycled aggregate after screening and impurity removal falls into the collection box 3 for collection, and the collection box 3 is limited by the limiting frame 4 to prevent the collection box 3 from tilting and sliding downward.
[0041] The working principle and use process of the utility model are as follows: first, the recycled aggregate is poured into the frame 222 through the feed hopper 214, and then the output end of the three-phase motor 241 drives the driving wheel 242 to cooperate with the belt 243 to drive the driven wheel 244 to rotate, and the driven wheel 244 drives the frame 222 to rotate through the shaft 221, so that the recycled aggregate can be screened and processed in sequence through the primary filter cartridge 223, the secondary filter cartridge 224, the tertiary filter cartridge 225 and the quaternary filter cartridge 226;
[0042] Then, the recycled aggregate in the screening process can fall into the corresponding lower hopper 231 below, and the metal impurities in the recycled aggregate are adsorbed by the conductive magnetic plate 232 after being energized; when the upward side of the conductive magnetic plate 232 is fully adsorbed, the output end of the servo motor 235 drives the conductive magnetic plate 232 to drive the circular plate 233 to rotate 180°, and the circular plate 233 drives the remaining circular plates 233 to rotate through the connecting rod 234, and the remaining circular plates 233 then drive the remaining conductive magnetic plates 232 to rotate synchronously, so that the other side of the conductive magnetic plate 232 faces upward and continues to adsorb metal impurities; and during the rotation of the conductive magnetic plate 232, the recycled aggregate accumulated in the lower hopper 231 is removed and can fall into the corresponding collection box 3 below for collection.
