Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] See also Figure 1-5 In this embodiment, a device for recovering concrete slag powder includes a workbench 1, a ramp frame 2 is installed on the top of the workbench 1, a recovery structure 3 is installed at the middle position of the top of the ramp frame 2, the recovery structure 3 includes a support frame 31, two first support seats 38 and two second support seats 311, a fixed seat 4 is installed on the top of the ramp frame 2, and a clearing structure 5 is installed on the top of the fixed seat 4; the clearing structure 5 includes two fixed frames 51, and inner grooves 52 are opened on both sides of the two fixed frames 51, and springs 53 are installed on both sides of the inner walls of the two inner grooves 52. A movable plate 54 is installed between the two springs 53, a connecting plate 55 is installed between the two movable plates 54, a plurality of top columns 56 are installed at the bottom of the connecting plate 55, a through slot 510 is opened at the top of the fixed frame 51, a third support seat 57 is installed on one side of the top of the fixed frame 51, a second motor 58 is installed inside the third support seat 57, a rotating disk 59 is installed at one end of the output shaft of the second motor 58, an eccentric column 511 is installed on one side of the rotating disk 59, a hinged rod 512 is sleeved on the outer surface of the eccentric column 511, and one end of the hinged rod 512 is hingedly connected to the connecting plate 55.
[0023] A roller 32 is rotatably mounted inside the support frame 31. Geared rings 33 are mounted on both sides of the outer surface of the roller 32. A partition plate 34 is mounted on one end of the roller 32. A screening drum 35 is mounted on one side of the partition plate 34. The screening drum 35 is connected to the fixed seat 4. An opening and closing door 41 is hingedly mounted on one side of the outer surface of the fixed seat 4. Two first support seats 38 are set on both sides of the roller 32. Two bidirectional rods 39 are mounted inside the two first support seats 38. Gears 310 are mounted on both ends of the two bidirectional rods 39, and the two gears 310 respectively mesh with the two geared rings 33. Two second support seats 311 are set on the right side of the first support seat 38. First motors 312 are mounted inside the two second support seats 311. The output shafts of the two first motors 312 are fixedly connected to the bidirectional rods 39. A connecting pipe 36 is rotatably mounted on one end of the right side of the roller 32. A blanking frame 37 is mounted on one side of the connecting pipe 36. The blanking frame 37 needs to be connected to the feeding equipment when working to prevent the connecting pipe 36 from driving the blanking frame 37 to rotate along with the drum 32.
[0024] By driving the first motors 312 on both sides, the output shafts thereof drive the bidirectional rods 39 to rotate, thereby enabling the toothed ring 33 to drive the roller 32 to rotate, thereby enabling the screening drum 35 to rotate at high speed following the same, and feeding the material into the discharge frame 37. Since the recovery structure 3 is slightly tilted as a whole, the vibration generated when the screening drum 35 rotates can screen the steel slag powder.
[0025] A drop chute 6 is provided on the top of the ramp frame 2, and a collecting frame 7 is placed inside the workbench 1. Finer slag is screened and falls into the collecting frame 7 from the holes of the screening cylinder 35, while larger slag powder falls out from the fixing seat 4.
[0026] Working principle: When in use, first connect the feeding frame 37 to the feeding equipment, and then feed the material. The output shaft of the first motor 312 on both sides drives the bidirectional rod 39 to rotate, thereby allowing the tooth ring 33 to drive the roller 32 to rotate, thereby allowing the screening drum 35 to follow its high-speed rotation, and feed the material in the feeding frame 37. Since the recovery structure 3 is slightly tilted as a whole, the vibration generated when the screening drum 35 rotates can screen the steel slag powder. After opening the opening and closing door 41, the finer steel slag screened from the holes of the screening drum 35 falls into the collecting frame 7, and the larger steel slag powder falls out from the fixing seat 4. After the screening work is completed, the larger steel slag powder stuck in the screening drum 35 is processed. When the large steel slag is finely powdered, the speed of the first motor 312 is lowered to match the speed of the second motor 58. At this time, by starting the second motor 58, its output shaft drives the rotating disk 59 to rotate. Due to the hinge of the eccentric column 511, the hinge rod 512 can drive the connecting plate 55 to move up and down in the inner groove 52. The connection of the spring 53 can avoid the movable plate 54 from colliding with the inner wall of the inner groove 52 to cause damage. As a result, the multiple top columns 56 at the bottom of the connecting plate 55 can be extended into the internal holes of the screening drum 35, pushing the steel slag stuck inside into the screening drum 35, and finally falling out from the fixed seat 4, thereby facilitating the cleaning of the recovery equipment screen and preventing blockage.
