[0002] Steel slag resource utilization equipment is a device for processing and reusing steel slag generated during the iron and steel smelting process. Through processes such as crushing, screening, magnetic separation, and grinding, it can effectively separate metallic iron and non-metallic minerals, realizing resource recycling. After processing, steel slag can be used as cement admixture, road base material, concrete aggregate, or other building material raw materials, which not only improves resource utilization but also reduces the environmental impact of solid waste stockpiling, thus contributing to the green and low-carbon development of the metallurgical industry.

[0003] In existing technologies, when larger steel slags remain in the screening frame after screening, the residual steel slags need to be cleaned manually. This not only involves a cumbersome and time-consuming process, but also increases the intensity and cost of manual labor and makes it difficult to guarantee the thoroughness of the cleaning. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a steel slag resource utilization device, including a support structure, a grinding device, a vibration structure, and a screening structure. The grinding device, vibration structure, and screening structure are respectively installed on the support structure. The screening structure includes a screening frame, a connecting shaft, and a screw. The screening frame is rotatably connected to a fixed frame via the connecting shaft. One end of the screw is rotatably installed on the outer wall of the fixed frame, and a turntable is fixedly installed on the other end of the screw. A connecting plate is threaded onto the screw, and insertion rods are fixedly installed at both ends of the connecting plate.

[0007] In a preferred embodiment of the steel slag resource utilization device of this utility model, the vibration structure includes a fixed plate, a fixed frame, a spring, and a crossbar. The fixed plate is fixedly installed on the support frame, and a sliding rod is fixedly installed on the top of the fixed plate. An ear block is fixedly installed on the outer wall of the fixed frame. The ear block is penetrated by the sliding rod, and the ear block and the sliding rod are slidably connected. The spring is sleeved on the sliding rod, and one end of the spring is fixedly connected to the fixed plate, and the other end is fixedly connected to the ear block.

Then, the screening frame can be directly rotated to pour out the larger steel slag inside. After pouring out, the screening frame can be re-fixed by aligning the limiting hole and the insertion rod and rotating the screw in the opposite direction. The whole process is convenient to operate and the structure is stable. It can efficiently complete the cleaning of residual steel slag after screening and the device reset, improving the continuity and convenience of steel slag treatment.

[0013] 2.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1

[0023] Refer to attached figure Figure 1 - Appendix Figure 3 This is the first embodiment of the present invention, which provides a steel slag resource utilization device, including a support structure 1, a grinding device 2, a vibration structure 3, and a screening structure 4. The grinding device 2, the vibration structure 3, and the screening structure 4 are respectively installed on the support structure 1. The support structure 1 includes a base plate 11, a support frame 12, and a collection box 14. The support frame 12 is fixedly installed on the top of the base plate 11, and the four corners of the bottom end of the base plate 11 are fixedly installed with support legs 13. The collection box 14 is installed on the top of the base plate 11, and the grinding device 2 is fixedly installed on the top of the support frame 12. The grinding device 2 belongs to the prior art.

[0024] The vibration structure 3 includes a fixed plate 301, a fixed frame 302, a spring 305, and a crossbar 306. The fixed plate 301 is fixedly mounted on the support frame 12. A sliding rod 304 is fixedly mounted on the top of the fixed plate 301. An ear block 303 is fixedly mounted on the outer wall of the fixed frame 302. The ear block 303 is penetrated by the sliding rod 304, and the ear block 303 and the sliding rod 304 are slidably connected. The screening structure 4 is installed inside the fixed frame 302. The spring 305 is sleeved on the sliding rod 304. One end of the spring 305 is fixedly connected to the fixed plate 301, and the other end is fixedly connected to the sliding rod 304. Ear blocks 303 are fixedly connected, crossbars 306 are fixedly installed between fixed plates 301, bearing seats 307 are fixedly installed in the middle of crossbars 306, motors 308 are fixedly installed on the outside of bearing seats 307, motor shafts of motors 308 extend through bearing seats 307 to the other end of bearing seats 307, and motor shafts of motors 308 and bearing seats 307 are rotatably connected, cams 309 are fixedly installed on motor shafts of motors 308, and arc blocks 310 are fixedly installed on the outer wall of fixed frame 302, with cams 309 and arc blocks 310 in contact.

[0025] During use, steel slag is poured into grinding equipment 2, where it is ground and then falls into screening structure 4. Motor 308 is started, and the motor shaft of motor 308 drives cam 309 to rotate. Cam 309 contacts arc block 310, causing fixed frame 302 to move up and down on slide rod 304 via ear block 303 and spring 305, thereby causing screening structure 4 to vibrate. The steel slag is screened by the vibration of screening structure 4, and the screened steel slag falls into collection box 14 for collection. Example 2

[0026] Refer to attached figure Figure 4 and attached Figure 5 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0027] The screening structure 4 includes a screening frame 41, a connecting shaft 42, and a screw 43. The connecting shaft 42 is fixedly installed at both ends of the screening frame 41 and extends into the fixed frame 302. The screening frame 41 is rotatably connected to the fixed frame 302 through the connecting shaft 42. One end of the screw 43 is rotatably installed on the outer wall of the fixed frame 302, and the other end of the screw 43 is fixedly installed with a turntable 44. A connecting plate 45 is threaded onto the screw 43. Insert rods 46 are fixedly installed at both ends of the connecting plate 45. The insert rods 46 pass through the fixed frame 302 and extend into the interior of the fixed frame 302. The insert rods 46 and the fixed frame 302 are slidably connected. The outer wall of the screening frame 41 is provided with limiting holes 47 that match the insert rods 46.

[0028] During use, steel slag falls into the screening frame 41. The up-and-down movement of the fixed frame 302 causes the screening frame 41 to vibrate, screening the steel slag through the screening frame 41. Larger steel slags remain inside the screening frame 41. After screening, the turntable 44 is rotated, which drives the screw 43 to rotate. The screw 43 controls the movement of the connecting plate 45, which in turn drives the insertion rod 46 to slide in the fixed frame 302. This causes the insertion rod 46 to disengage from the limiting hole 47, thereby releasing the limitation on the screening frame 41. The screening frame 41 is then rotated to pour out the screened steel slag. After pouring, the limiting hole 47 and the insertion rod 46 are aligned. The screw 43 is then rotated to re-insert the insertion rod 46 into the limiting hole 47.

[0029] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
