[0002] Recycled concrete is a building material made by crushing, screening and washing discarded concrete. The raw materials of recycled concrete usually contain sand, gravel, organic matter, steel bars and other impurities. In order to ensure the quality and performance of recycled concrete, it is necessary to remove impurities. When removing iron impurities such as steel bars, the concrete that is crushed and transmitted outward is generally adsorbed and removed by a magnetic adsorption structure to separate the iron impurities in the concrete fragments, and then the entire magnetic structure is rotated and adjusted to the top of the collection frame. During this process, the magnetic structure still has a magnetic attraction, but its magnetic attraction to the iron material on the transmission structure will gradually decrease with increasing distance. In addition, the iron material that is magnetically attracted at this stage may also collide with other structures on the device, which may easily cause the iron material adsorbed during the rotation of the magnetic structure to fall off.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In order to solve the problem that the iron impurities in some recycled concrete are removed in the existing recycled concrete impurity removal structure, the iron materials adsorbed by the magnetic suction structure may fall down during the rotation process. Figure 1-Figure 4 , an embodiment provided by the utility model:

[0022] A regenerated concrete impurity removal structure, comprising a crushing component 1, a conveying component 2 is installed on the crushing component 1, a transfer component 3 is installed on the conveying component 2, two support plates 4 arranged front and back are fixedly installed on one side of the conveying component 2, a hydraulic cylinder 5 is installed on the top of the support plate 4, an electric magnetic attraction structure 6 is installed on the free end of the hydraulic cylinder 5, the transfer component 3 comprises a collection frame 301 placed on the other side of the conveying component 2, a multi-section electric push rod 302 is installed on the top of one side of the conveying component 2, a T-shaped cylinder 303 is installed on the free end of the multi-section electric push rod 302, a sleeve structure 304 is rotatably sleeved on the outer surface of the T-shaped cylinder 303, a sliding frame 305 which is gradually inclined downward from one side to the side close to the collecting frame 301 is fixedly installed on the back of the sleeve structure 304, support plates 306 are fixedly installed on both sides of the bottom of the sliding frame 305, the length of the sliding frame 305 is greater than the length of the electric magnetic attraction structure 6, and one side of the sliding frame 305 extends to the top of the collecting frame 301;

[0023] In the present device, the recycled concrete is put into the space inside the crushing component 1, and the crushing component 1 is used to crush the larger blocks of recycled concrete into smaller blocks, and then the smaller blocks fall down to the upper surface of the conveying component 2. As the conveying component 2 is conveying, the small blocks of concrete pass under the electric magnetic structure 6 at a certain speed, and at this time, the hydraulic cylinder 5 is in a downward extension state, so that the electric magnetic structure 6 is close to the concrete on the upper surface of the conveying component 2 below. The electric magnetic structure 6 is used to continuously absorb the iron in the concrete fragments conveyed outward through the conveying component 2, so as to achieve the purpose of removing the iron in the recycled concrete. In addition, when the outer surface of the electric magnetic structure 6 is more adsorbed, the hydraulic cylinder 5 is used to The upward contraction drives the electric magnetic structure 6 to move upward, and adjusts it to the upper side of the sliding frame 305. Thereafter, the multi-section electric push rod 302 is extended or contracted backward by a set length, so as to adjust the sliding frame 305 to the right below the electric magnetic structure 6 to be cleaned through the T-shaped cylinder 303 and the sleeve structure 304. At the same time, the electric magnetic structure 6 is disconnected from the power supply according to the set program. At this time, the iron material adsorbed on its surface falls directly into the sliding frame 305, and slides down autonomously to the inside of the collection frame 301, so as to achieve the purpose of conveniently cleaning the adsorbed iron material. Thereafter, the sliding frame 305 returns to its original position, and the two electric magnetic structures 6 in the device work together to ensure the uninterrupted removal of iron impurities from concrete fragments.

[0024] Specifically, when there is iron material in the slide frame 305 that has not slid down into the collection frame 301, the staff can lift up the higher side of the slide frame 305, control the sleeve structure 304 to rotate upward along the outer surface of the T-shaped cylinder 303, and increase the inclination of the slide frame 305 to assist the iron material to slide into the collection frame 301.

[0026] The driving structure 104 runs, driving the crushing rollers 102 to rotate at a set speed, and then squeezes the concrete blocks between the two crushing rollers 102 to crush them into small pieces that fall downwards. In addition, the two additional crushing racks 103 can effectively improve the comprehensiveness of the crushing of the concrete blocks and prevent them from falling downwards along the gap between the crushing rollers 102 and the equipment housing 101. The retractable delivery port 105 can, to a certain extent, prevent the fragments from splashing upwards during the crushing process.
