Description

Technical Field

[0001] The present invention belongs to the technical field of steel slag treatment, and specifically refers to a steel slag treatment device for improving the iron recovery rate in steel slag. Background Art

[0002] Steel slag is one of the main solid wastes generated in the iron and steel smelting process, and it contains a certain amount of iron elements. Traditional steel slag treatment methods usually adopt simple crushing and magnetic separation processes. However, due to the complex composition and uneven hardness of steel slag, the recovery rate of iron elements is relatively low, and problems such as equipment wear and high energy consumption are prone to occur during the treatment process. In the prior art, most steel slag crushing devices are driven by a single power, which is difficult to meet the crushing requirements of steel slag with different hardnesses, resulting in low crushing efficiency. At the same time, the design of the magnetic separation mechanism is often relatively simple, unable to achieve efficient and continuous iron element recovery, further reducing the resource utilization rate.

[0040] The support housing assembly 1 includes a fixed base 101, a detachable housing 102, a collection box 103, a cover plate 104, and a feed hopper 105. The detachable housing 102 is fixedly connected to the fixed base 101. The collection box 103 penetrates and is slidably connected to the detachable housing 102. The cover plate 104 is fixedly connected to the top end of the detachable housing 102. The feed hopper 105 penetrates and is fixedly connected to the cover plate 104.

[0041] The position of the feed hopper 105 corresponds to the position of the crushing container 201.

[0042] During specific use, the steel slag is fed into the interior of the crushing container 201 through the feed hopper 105. The crushing drive motor 205 is started. The crushing drive motor 205 drives the driving bevel gear 207 to rotate through the first key shaft 206. The driving bevel gear 207 drives the driven bevel gear 209 to rotate. The driven bevel gear 209 drives the second key shaft 212 to rotate through the connecting sleeve 210. The second key shaft 212 drives the rotating shaft 202 to rotate through the docking shaft 213. A docking gear 203 is provided on the second key shaft 212. The rotating shaft 202 rotates synchronously and in the opposite direction under the action of the docking gear 203. Thus, the crushing blades 204 provided on the rotating shaft 202 crush the steel slag entering the crushing container 201.

[0043] When there are steel slag blocks with relatively high hardness during the process of crushing the steel slag, the driving force transmitted by the crushing drive motor 205 through the driving bevel gear 207 cannot complete the crushing of the steel slag blocks. At this time, the crushing blades 204 cannot rotate, and the rotating disc 214 stops rotating. The movable rod 217 provided on the rotating disc 214 contracts inward under the action of the telescopic spring 218. At this time, the movable rod 217 drives the driving bevel gear 208 to displace along the first key shaft 206 through the fixed rod 219 and the connecting plate 222 provided on the fixed rod 219. At the same time, the movable rod 217 drives the connecting sleeve 210 to displace along the second key shaft 212 through the transmission rod 220 and the connecting plate 222 provided on the transmission rod 220. The driven bevel gear 209 disengages from the driving bevel gear 207 and engages with the driving bevel gear 208. After the driving bevel gear 208 and the driven bevel gear 209 are engaged, the force for driving the rotating shaft 202 to rotate increases, and the force for squeezing the steel slag also increases accordingly, so that the steel slag that could not be broken originally is crushed.

[0044] After the obstructing steel slag is crushed, the rotating disk 214 resumes rotation. At this time, the movable rod 217 provided on the rotating disk 214 expands outwards under the action of centrifugal force, and drives the second driving bevel gear 208 to disengage from the driven bevel gear 209. At the same time, the driven bevel gear 209 is initially engaged with the first driving bevel gear 207, enabling the rotating shaft 202 to rotate normally. After the driven bevel gear 209 is engaged with the first driving bevel gear 207, the rotation speed of the rotating disk 214 increases, thereby driving the second driving bevel gear 208 and the driven bevel gear 209 to reset to the initial position.

[0045] Start the feeding drive motor 302. The feeding drive motor 302 drives the conveyor belt 304 to rotate through the output shaft 303. At the same time, the driving pulley 305 and the transmission belt 309 drive the driven pulley 308 to rotate. The driven pulley 308 drives the cam 313 to rotate, causing the cam 313 to drive the vibrating plate 311 to vibrate up and down along the sliding groove 310. The crushed steel slag falls on the upper surface of the conveyor belt 304 and is conveyed by the conveyor belt 304. During the conveying process of the steel slag, the power supply 409 supplies power to the electromagnet 410, causing the electromagnet 410 to generate magnetic force and adsorb the iron-containing debris in the steel slag on the upper surface of the conveyor belt 304. The time relay 407 provided on the upper surface of the support plate 401 sends a signal to the controller 408 after reaching the preset time. After receiving the signal, the controller 408 first starts the electric telescopic rod 402. The electric telescopic rod 402 drives the reciprocating rack 403 to displace. The reciprocating rack 403 drives the rotating mounting rod 404 to rotate synchronously in the opposite direction through the adjusting gear 406, causing the electromagnet 410 to move above the collection box 103. Subsequently, the controller 408 controls the power supply 409 to stop power supply. After the electromagnet 410 loses power supply, the magnetic force disappears, and the iron debris originally adsorbed on the electromagnet 410 falls into the interior of the collection box 103. Subsequently, the electric telescopic rod 402 drives the reciprocating rack 403 to reset, and the reciprocating rack 403 drives the rotating mounting rod 404 to reset. At the same time, the power supply 409 resumes power supply to the electromagnet 410.

[0046] Finally, the staff can regularly pull out the collection box 103 from the detachable housing 102 and clean the collection box 103. The above is the overall working process of the present invention. Just repeat this step during the next use, and the actual operation process is very simple and easy.
