Description

Technical Field

[0001] This utility model relates to the technical field of steel slag screening devices, specifically a steel slag particle size screening device. Background Technology

[0002] A byproduct of the steelmaking process, it consists of various oxides formed by the oxidation of impurities such as silicon, manganese, phosphorus, and sulfur in pig iron during the smelting process, as well as salts formed by the reaction of these oxides with solvents. It is divided into three types: electric furnace slag, open-hearth furnace slag, and converter slag.

[0003] There are two main ways to comprehensively utilize steel slag as a secondary resource. One is to use it as a smelting solvent and recycle it in the plant. It can not only replace limestone, but also recover a large amount of metallic iron and other useful elements. The other is to use it as a raw material for manufacturing road construction materials, building materials or agricultural fertilizers.

[0004] After steel slag is produced, it needs to be screened and cleaned. Screening often uses multi-stage screening, but existing multi-stage screening requires changing containers with different apertures, which is inefficient. Some containers that can change the aperture can only change the aperture on one side, and cannot increase or decrease the aperture proportionally. Screening accuracy needs to be further improved. Therefore, we propose a steel slag particle size screening device. Utility Model Content

[0005] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0025] The following describes, with reference to the accompanying drawings, some embodiments of a steel slag particle size screening device provided by this utility model.

[0026] Combination Figure 1-3 As shown, the present invention provides a steel slag particle size screening device, comprising: a frame 100 and a screening component 200 disposed on the frame 100.

[0027] The screening assembly 200 includes a screening mechanism mounted on the frame 100, an adjustment mechanism disposed on the screening mechanism, and a feeding mechanism mounted on the end of the screening mechanism. The adjustment mechanism includes an adjustment cage 310 fitted on the outside of the screening mechanism, an adjustment hole 320 opened on the adjustment cage 310, an annular rail 330 mounted on the end of the adjustment cage 310, a locking block 340 locked in the annular rail 330, an electric telescopic rod 350 connected to the locking block 340 and mounted on the screening mechanism, and a feeding mechanism disposed on the annular rail 310. The toothed ring 360 on the outer side of the rail 330, the gear 370 meshing with the toothed ring 360, and the motor 380 connected to one side of the gear 370, through the screening assembly 200, can drive the gear 370 to rotate using the motor 380, adjust the position of the adjusting cage 310 on the screening cage 220, so that the adjusting hole 320 and the screen hole 230 are vertically offset. Then, the electric telescopic rod 350 drives the adjusting cage 310 to move horizontally, thereby horizontally offsetting the adjusting hole 320 and the screen hole 230, realizing the proportional increase or decrease of the screen hole, which greatly improves the screening accuracy of steel slag.

[0028] Specifically, the screening mechanism includes a motor 210 mounted on the frame 100, a screening cage 220 fixed to the drive end of the motor 210 and mounted on the frame 100, and screen holes 230 opened on the screening cage 220. The motor 210 can drive the screening cage 220 to rotate, and steel slag of the appropriate size can be discharged from the screen holes 230.

[0029] Furthermore, the feeding mechanism includes a feeding cylinder 410 mounted on the frame 100, a feeding chamber 420 opened in the feeding cylinder 410, a feeding hole 430 opened above the feeding chamber 420, an inner liner 440 disposed in the feeding cylinder 410, an extension ring 450 fixed to the end of the feeding cylinder 410 and extending into the screening cage 220, a bearing 460 installed at the end of the screening cage 220 for supporting the feeding cylinder 410, and a feeding bin 470 connected to the bearing 460. Through the screening assembly 200, steel slag can be directly fed into the feeding chamber 420 and then flow into the screening cage 220. In conjunction with the vibrator 443, the vibrating plate 441 is vibrated to accelerate the entry of steel slag, which is highly practical.

[0030] On the other hand, a vibrating plate 441 is embedded in the inner side of the inner liner 440. A vibrating rod 442 is connected to the vibrating plate 441, and a vibrator 443 is connected to the end of the vibrating rod 442. The vibration generated by the vibrator 443 can be transmitted to the vibrating plate 441, thereby accelerating the discharge of steel slag and preventing blockage.

[0031] Furthermore, the diameter of the feeding chamber 420 gradually increases from the outer to the inner part, which facilitates the smooth discharge of steel slag and is a relatively reasonable design.

[0032] On the other hand, the sieve hole 230 and the adjustment hole 320 are square holes with the same hole diameter. Using square holes can better adjust the hole diameter proportionally. Compared with adjustment from one side, it can screen steel slag of different sizes more evenly, so as to prevent the discharge of irregularly shaped steel slag with unsuitable specifications.

[0033] The working principle and usage process of this utility model are as follows: First, steel slag is continuously fed into the discharge chamber 420 through the feeding bin 470. Then, the steel slag flows into the screening cage 220. At the same time, motor 210 drives the screening cage 220 to rotate, and then motor 380 drives the gear 370 to rotate, adjusting the position of the adjusting cage 310 on the screening cage 220 so that the adjusting hole 320 and the screen hole 230 are vertically offset. Then, the electric telescopic rod 350 drives the adjusting cage 310 to move horizontally, thereby horizontally offsetting the adjusting hole 320 and the screen hole 230, realizing the proportional increase or decrease of the screen hole. After the hole diameter is adjusted, steel slag of the correct size is discharged from the screen hole 230. Then, the hole diameter of the adjusting screen hole 230 is increased again in the above manner until all the steel slag in the batch is discharged and collected in sections.

[0034] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
