Description

Technical Field

[0001] This utility model relates to the field of steel slag technology, and in particular to a grate structure for steel slag treatment. Background Technology

[0002] Steel slag is 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. When using a hot quenching tank to cool steel slag, a grate structure is needed to block the steel slag and to discharge wastewater during water spray cooling.

[0003] A search revealed a Chinese patent (application number "202122327076.3") that discloses "a water grate structure for a hot quenching tank for steel slag treatment." This grate structure includes a grid baffle; a grid baffle, side plates, and two end plates are fixed along the edge of the grid bottom plate. The grid baffle and side plates are arranged opposite each other, and the two end plates are arranged opposite each other, forming a four-sided enclosed space. However, during use, when steel slag is transported into the hot quenching tank, some of the molten steel slag will be discharged to the outside through the drain holes of the grate structure. When the steel slag cools, the drain holes become clogged, resulting in low practicality. Utility Model Content

[0004] This utility model provides a grate structure for steel slag treatment, which solves the problem proposed in the prior art that when the grate structure is in use, partially molten steel slag will be discharged to the outside along the drainage holes of the grate structure, and the drainage holes will be blocked when the steel slag cools, resulting in low practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A grate structure for steel slag treatment includes a hot quenching tank. The hot quenching tank includes a tank body and a bottom plate fixed to the lower inner wall of the tank body. A drainage mechanism is provided at the bottom of the tank body. The drainage mechanism includes two mounting frames fixed to the inner wall of the bottom of the tank body and drainage covers fixed to the outer walls of the two mounting frames on both sides. A sealing mechanism is provided at the lower part of the tank body. The sealing mechanism includes four lifting cylinders respectively bolted to the inner wall of the bottom of the tank body, mounting blocks bolted to the outer wall of the piston rod of the lifting cylinders, and several sealing plates respectively fixed to the outer wall of the top of the mounting blocks. Several heat exchange mechanisms are provided on the mounting blocks. The heat exchange mechanisms include connecting plates bolted to the outer wall of the bottom of the mounting blocks, several heat exchange plates respectively fixed to the outer wall of the top of the connecting plates, and several heat dissipation plates fixed to the outer wall of the bottom of the connecting plates. A heat dissipation mechanism is provided on one side of the bottom of the mounting blocks. The heat dissipation mechanism includes a mounting plate and several heat dissipation fans bolted to the outer wall of one side of the mounting plate.

[0007] Preferably, the bottom plate has several drainage holes on its top outer wall, the pool body has an installation port on its lower outer wall on one side, and the pool body has an air outlet on its lower outer wall away from the installation port.

[0008] Preferably, the two mounting frames are fixed to the inner walls of the pool body on both sides, and a gap is left between one side of the two mounting frames and the pool body.

[0009] Preferably, the upper parts of the four lifting cylinders are connected in pairs to the inner walls of the top of the two mounting frames by bolts. The mounting block is slidably installed on the inner wall of the lower part of the pool. Several sealing plates are respectively inserted into several drainage holes. Two first drainage ports are opened on the outer wall of the bottom of the mounting block, and several second drainage ports are opened on the outer wall of the bottom of the mounting block located between the two first drainage ports.

[0010] With the above solution, the sealing plate is inserted into the drain hole. When the steel slag is transported into the hot quenching tank, the sealing plate seals the molten steel slag in the hot quenching tank. When the temperature of the steel slag drops to 300℃-400℃, the steel slag is sprayed with water. At this time, the piston rod of the lifting cylinder descends, driving the mounting block and the sealing plate to descend, thereby causing the sealing plate to detach from the drain hole, so that the wastewater can be discharged from the drain hole.

[0011] Preferably, the mounting block and the top outer wall of the sealing plates are all provided with through holes, and the heat exchange plates are respectively fitted into the through holes.

[0012] Preferably, the mounting plate is bolted to the bottom outer wall of the mounting block, and the mounting plate is slidably sleeved on the inner wall of one side of the pool body, with several cooling fans slidably sleeved in the mounting openings.

[0013] The above scheme involves contacting the heat exchange plate with the steel slag, allowing the heat in the steel slag to be exchanged with the heat exchange plate, and then the heat is transferred to the heat dissipation plate. Multiple sets of cooling fans operate, cooling the heat dissipation plate, and hot air is discharged from the air outlet. When the piston rod of the lifting cylinder descends, the cooling fans move within the installation port.

[0014] The beneficial effects of this utility model are as follows:

[0015] The sealing plate is inserted into the drain hole. When steel slag is transported into the hot quenching tank, the sealing plate seals the molten steel slag in the hot quenching tank. When the temperature of the steel slag drops to 300℃-400℃, water is sprayed onto the steel slag. At this time, the piston rod of the lifting cylinder descends, driving the mounting block and the sealing plate to descend, thereby causing the sealing plate to detach from the drain hole, allowing wastewater to be discharged from the drain hole. This prevents molten steel slag from entering the drain hole and causing blockage when the steel slag is transported into the hot quenching tank, thus improving practicality.

An air outlet 12 is opened on the lower outer wall of the tank body 101 away from the installation port 11. A drainage mechanism 2 is provided at the bottom of the tank body 101. The drainage mechanism 2 includes two installation frames 201 fixed to the bottom inner wall of the tank body 101 and drainage covers 202 fixed to the middle outer walls of the two installation frames 201 on both sides. The two installation frames 201 are fixed to the inner walls of the tank body 101 on both sides. A gap is left between one side of the two installation frames 201 and the tank body 101. A water outlet is opened on one side of the tank body 101. The water outlet is connected to the drainage cover. The bottom inner wall of 202 is tangent. The lower part of the pool body 101 is provided with a sealing mechanism 3. The sealing mechanism 3 includes four lifting cylinders 301 that are respectively bolted to the bottom inner wall of the pool body 101, mounting blocks 302 that are bolted to the outer wall of the piston rod of the lifting cylinders 301, and several sealing plates 303 that are respectively fixed to the top outer wall of the mounting blocks 302. The upper parts of the four lifting cylinders 301 are respectively bolted to the top inner wall of the two mounting frames 201. The mounting blocks 302 are slidably installed on the lower inner wall of the pool body 101. Several sealing plates 303 are respectively inserted into several drainage holes 103. Two first drainage ports 31 are opened on the bottom outer wall of the mounting blocks 302. Several second drainage ports 32 are opened on the bottom outer wall of the mounting blocks 302 between the two first drainage ports 31.

[0027] Example 2, refer to Figure 7-8 A grate structure for steel slag treatment includes several heat exchange mechanisms 4. Each heat exchange mechanism 4 includes a connecting plate 401 bolted to the bottom outer wall of a mounting block 302, several heat exchange plates 402 respectively fixed to the top outer wall of the connecting plate 401, and several heat dissipation plates 403 fixed to the bottom outer wall of the connecting plate 401. Through holes are formed on the top outer walls of the mounting block 302 and the several sealing plates 303. The several heat exchange plates 402 are respectively fitted into the several through holes. A heat dissipation mechanism 5 is provided on one side of the bottom of the mounting block 302. The heat dissipation mechanism 5 includes a mounting plate 501 and several heat dissipation fans 502 that are bolted to the outer wall of one side of the mounting plate 501.

[0028] Working principle: The sealing plate 303 is inserted into the drain hole 103. When the steel slag is transported into the hot quenching tank 1, the sealing plate 303 seals the molten steel slag in the hot quenching tank 1. When the temperature of the steel slag drops to 300℃-400℃, the steel slag is sprayed with water. At this time, the piston rod of the lifting cylinder 301 descends, driving the mounting block 302 and the sealing plate 303 to descend, thereby causing the sealing plate 303 to detach from the drain hole 103, allowing the wastewater to be discharged from the drain hole 103. The heat exchange plate 402 comes into contact with the steel slag, allowing the steel slag to exchange heat with the heat exchange plate 402. Subsequently, the heat is transferred to the heat dissipation plate 403. Multiple sets of heat dissipation fans 502 operate, and the heat dissipation fans 502 cool the heat dissipation plate 403, allowing hot air to be discharged from the air outlet 12. When the piston rod of the lifting cylinder 301 descends, the heat dissipation fans 502 move within the mounting port 11.
