Description

Technical Field

[0001] The present application relates to the field of metallurgical technology, and in particular to a low-cost cooling system for high-temperature solid steel slag. Background Art

[0002] The efficient recovery of metallic iron and inorganic material resources in steel slag must first be crushed and separated, and then the two types of materials are separated by magnetic separation, so as to achieve targeted resource utilization. The pretreatment process of steel slag is a prerequisite for the crushing and magnetic separation of steel slag. Pretreatment under high temperature conditions can achieve more efficient crushing, screening and magnetic separation of steel slag.

[0003] At present, the pretreatment process of steel slag is the hot stuffing method. The hot stuffing method is the most commonly used process for steel slag treatment. It has a series of advantages such as wide adaptability, good slag pulverization effect after hot stuffing, slag iron separation, high recovery rate of metallic iron, and qualified tailing stability. The hot stuffing method is divided into two processes: pool hot stuffing and pressurized hot stuffing. Among them, the pressurized hot stuffing method uses a mechanized roller crusher to crush the high-temperature steel slag, realizing the equipment automation of the crushing process, but the hot stuffing system uses a large number of pressure vessels, the system equipment occupies a large space, and the investment is high. In addition, this method is to pour the high-temperature steel slag in the water-cooled tank into the hot stuffing pool and then perform water cooling. After cooling, the cooled high-temperature steel slag is loaded into the water-cooled tank and transported to the next workstation, which is very troublesome and wastes manpower and material resources. Therefore, the present application provides a low-cost cooling system for high-temperature solid steel slag to solve the above problems. Utility Model Content

[0039] The present application embodiment provides a low-cost cooling system for high-temperature solid steel slag, referring to Figure 1 to Figure 2 The low-cost cooling system for high-temperature solid steel slag includes a water cooling box 10, a water sealing tank 20, a water cooling tank 30 and a water cooling cover 40 with raised edges on all sides.

[0040] The top of the water cooling box 10 is open, the water sealing groove 30 is fixedly arranged on the top of the water cooling box 10, and a through hole leading from the outside to the inside of the water cooling box 10 is arranged in the middle position of the water sealing groove 20.

[0041] The main body of the water cooling box 10 is a square trough body of a concrete structure, that is, the side walls and the bottom of the water cooling box are both concrete structures. The thickness of the side walls of the water cooling box is 150mm to 600mm, and the thickness of the bottom is not less than 200mm.

[0042] The water cooling cover 40 is arranged above the water sealing groove 20, and the periphery of the water cooling cover 40 is arranged in the water sealing groove 20, and there is a gap between the water cooling cover 40 and the bottom of the water sealing groove 20. The interior of the water cooling box 10 can be connected with the outside through the gap, wherein water is arranged in the water sealing groove 20 to prevent the gas inside the water cooling box 10 from entering the outside through the gap, and to maintain a certain pressure inside the water cooling box 10. The water cooling cover 40 can rotate relative to the top of the water cooling box 10 to open or close the top of the water cooling box 10.

[0043] When the water-cooling cover 40 covers the top of the water-cooling box 10, the periphery of the water-cooling cover 40 is located in the water seal groove 20, and there is a gap between the water-cooling cover 40 and the bottom of the water seal groove 20. At this time, the water-cooling cover 40 is not close to the groove wall of the water seal groove 20, and there is a gap between the two. If there is no water in the water seal groove 20, the gas inside the water-cooling box 10 can enter the outside through these gaps. By adjusting the amount of water in the water tank (water seal height), a certain pressure can be maintained inside the water-cooling box 10, so there is no need to set up a large number of pressure vessels to maintain the pressure inside the water-cooling box 10, thereby greatly reducing the investment cost. The pressure inside the water-cooling box 10 is maintained at 1KPa to 5KPa.

[0044] The water cooling cover 40 may be a square structure cover. When the water cooling cover 40 covers the top of the water cooling box 10, the four sides of the water cooling cover 40 may be water-sealed through the water sealing groove 20. The depth of the water sealing groove 20 is 200 mm to 600 mm.

[0045] The main bodies of the water-cooling cover 40 and the water seal groove 20 are both made of steel structural materials, and the thickness of the steel used is 8 mm to 25 mm.

[0046] A plurality of water outlet holes 50 are arranged around the tank body of the water cooling tank 30, and the water cooling tank 30 is used to hold high-temperature steel slag that needs to be cooled and crushed.

[0047] The water cooling tank 30 is a steel structure tank body, the tank wall thickness of the water cooling tank 30 is not less than 30 mm, and the water outlet holes 50 are evenly distributed at the lower part of the water cooling tank 30 .

[0048] A water sprinkling mechanism 60 is disposed at the bottom of the water cooling cover 40 , and a boss 70 for placing the water cooling tank 30 is disposed at the bottom of the water cooling box 10 .

[0049] The watering mechanism 50 is used to cool and crush the high-temperature steel slag in the water-cooling tank 30 , and the water outlet 50 is used to discharge the water in the water-cooling tank 30 .

[0050] Among them, when the high-temperature steel slag in the water-cooling tank 30 needs to be cooled and crushed, the water-cooling box 10 is first placed on the boss 70, and then water is sprinkled into the water-cooling box 10 through the sprinkler mechanism 50. When the high-temperature steel slag in the water-cooling tank 30 is cooled, the water-cooling tank 30 can be directly moved to the next workstation.

[0051] The embodiment of the present application can directly perform water cooling operation on the high-temperature steel slag in the water-cooling tank 30, and the water in the water-cooling tank 30 can flow out from the through hole, so that the high-temperature steel slag in the water-cooling tank 30 does not need to be poured into the bottom of the water-cooling box 10 and then the water-cooling operation is performed, which reduces the manpower and material resources required to load the cooled high-temperature steel slag into the water-cooling tank 30 after the high-temperature steel slag is cooled, greatly reducing costs and improving efficiency. In addition, by setting the water seal groove 20, the water cooling cover 40 and the water seal groove 20 are gap-matched, and then by adjusting the amount of water in the water seal groove 40, it is possible to maintain a certain pressure inside the water-cooling box 10, and there is no need to set up a large number of pressure vessels to maintain the pressure inside the water-cooling box 10, thereby greatly reducing the investment cost.

[0052] In some embodiments, the diameter of the water outlet hole 50 is 2 mm to 6 mm.

[0053] Considering that if the water outlet hole 50 is too large, the slag particles will be flushed out of the water cooling tank 30, and if the water outlet hole 50 is too small, the fine slag particles will clog the water outlet hole 50, the hole diameter of the water outlet hole 50 is set to 2 mm to 6 mm.

[0054] In some embodiments, the height of the boss 70 ranges from 0.2 m to 0.3 m.

[0055] Considering that a certain height of the boss is conducive to drainage, but too high a height requires increasing the height of the entire system such as the water cooling box 10, which will increase the manufacturing cost, the height of the boss 70 is set within the range of 0.2m to 0.3m.

[0056] In some embodiments, a drainage hole 80 is disposed on the bottom side wall of the water cooling box 10 , and a drainage groove 90 is disposed on the outside of the water cooling box 10 , and the drainage groove 90 is connected to the drainage hole 80 .

[0057] The drainage hole 80 and the drainage groove 90 are used to drain the water in the water cooling box 10 .

[0058] The main body of the drainage groove 90 is a concrete structure, with a width of 300 mm to 800 mm and a depth of 400 mm to 800 mm. The diameter of the drainage hole 80 is 100 mm to 400 mm.

[0059] In some embodiments, a mesh screen is provided on one side of the drainage hole 80 located inside the water cooling box 10 .

[0060] The mesh screen is used to prevent excessive fine slag from flowing into the drainage trough 90. The mesh screen can be a stainless steel mesh screen.

[0061] In some embodiments, the low-cost cooling system for high-temperature solid steel slag further includes a flue gas dust removal mechanism 100 , and a first exhaust channel 110 is disposed on the water-cooled cover 40 , and the first exhaust channel 110 is connected to the flue gas dust removal mechanism 100 .

[0062] The first exhaust passage 110 is used to exhaust the water vapor in the water cooling box 10. The water vapor coming out of the first exhaust passage 110 enters the flue gas dust removal mechanism 100, and is discharged to the outside after being processed by the flue gas dust removal mechanism 100.

[0063] In some embodiments, the flue gas dust removal mechanism 100 includes an exhaust pipe 1001, a wet dust collector 1002, an induced draft fan 1003 and a chimney 1004; the first exhaust channel 110 is connected to the hollow rotating shaft 120 on the water-cooled cover 40, and the hollow rotating shaft 120 is connected to the wet dust collector 1002 through the exhaust pipe 1001, and the wet dust collector 1002, the induced draft fan 1003 and the chimney 1004 are connected in turn through the exhaust pipe 1001.

[0064] The hollow rotating shaft 120 and the water cooling cover 40 are fixedly connected, and the hollow rotating shaft 120 and the exhaust pipe 1001 are rotatably connected.

[0065] In some embodiments, a second exhaust passage 130 is provided on the side wall of the water cooling box 10 , and the second exhaust passage 130 is connected to the flue gas dust removal mechanism 100 .

[0066] Specifically, the second exhaust passage 130 is connected to the first exhaust pipe 1001 in the flue gas dust removal mechanism 100 through an exhaust pipe. The first exhaust pipe is the exhaust pipe 1001 connecting the hollow rotating shaft 120 and the wet dust collector 1003 .

[0067] The second exhaust passage 130 is used to exhaust the water vapor in the water cooling box 10. The water vapor coming out of the second exhaust passage 130 enters the flue gas dust removal mechanism 100, and is discharged to the outside after being processed by the flue gas dust removal mechanism 100.

[0068] The reason why the first exhaust channel 110 and the second exhaust channel 130 are provided at the same time is that the two exhaust channels are more conducive to exhaust. Although the first exhaust channel 110 is conducive to the exhaust of system smoke, it is limited by the fact that the hollow rotating shaft 120 should not be too large, and only the first exhaust channel 110 is not enough to support exhaust. Therefore, it is more appropriate to provide the first exhaust channel 110 and the second exhaust channel 130 at the same time. The channel diameter of the second exhaust channel 130 can be set larger.

[0069] The aperture of the second exhaust passage 130 is 300 mm to 1200 mm.

[0070] In some embodiments, the high-temperature solid steel slag low-cost cooling system also includes a support base 140 arranged outside the water cooling box 10; a hydraulic cylinder 150 is arranged on the support base 140, and the hydraulic cylinder 150 is fixedly connected to the hollow rotating shaft 120 on the water cooling cover 40 through a traction plate 160. The hydraulic cylinder 150 is used to drive the water cooling cover 40 to rotate relative to the top of the water cooling box 10 to open or close the top of the water cooling box 10.

[0071] The traction plate 160 is a steel structure, and the thickness of the main steel plate is 20 mm to 60 mm. The traction plate 160 is used for the hydraulic cylinder 150 to pull and push the water cooling cover 40 to open or close.

[0072] The hydraulic cylinder 150 and the traction plate 160 are fixedly connected, and the traction plate 160 and the hollow rotating shaft 120 are fixedly connected.

[0073] In some embodiments, the high-temperature solid steel slag low-cost cooling system further includes a lifting mechanism 170 , and the lifting mechanism 170 is used to lift the water-cooling tank 30 .

[0074] Among them, the lifting mechanism 170 is used to transfer the water-cooling tank 30 filled with high-temperature solid steel slag to the boss 70 in the water-cooling tank 30, and after the high-temperature solid steel slag in the water-cooling tank 30 is water-cooled, transfer the water-cooling tank 30 on the boss 70 to the next workstation.

[0075] In some embodiments, a cushion layer 180 is disposed at the bottom of the water cooling box 10 .

[0076] The cushion layer 180 is used to prevent the solid slag in the water cooling tank 30 from falling to the bottom of the water cooling box 10 and causing damage to the bottom.

[0077] The cushion layer 180 is granular steel slag, slag or crushed stone, and the particle size is 20 mm to 50 mm.

[0078] The working principle of the low-cost cooling system for high-temperature solid steel slag is as follows: (1) A hydraulic cylinder 150 is used to open the water-cooling cover 40 above the water-cooling box 10, and then a lifting mechanism 170 is used to lift the water-cooling tank 30 containing high-temperature steel slag at a certain temperature to the boss 70 in the water-cooling box 10, and finally, a hydraulic cylinder 150 is used to close the water-cooling cover 40 above the water-cooling box 10; (2) The watering mechanism 60 below the water-cooling cover 40 is opened to cool the high-temperature steel slag in the water-cooling tank 30 with water at a certain water pumping rate. During the water pumping cooling process, a slightly positive pressure atmosphere with a certain pressure is maintained in the water-cooling box 10 until the high-temperature steel slag is cooled to a certain temperature condition by water pumping; (3) The high-temperature steel slag in the water-cooling tank 10 encounters water to generate a large amount of water vapor, and the water vapor is discharged through the second exhaust channel 130 and the first exhaust channel 130. The exhaust passage 110 enters the exhaust pipe 1001 respectively, and then passes through the wet dust collector 1002 and the chimney 1004 to meet the standards and be discharged outside; (4) The water that has not evaporated and is pumped into the water cooling tank 30 by the water sprinkling mechanism 60 is discharged from the water outlet holes 50 around the lower tank wall of the water cooling tank 30, and then flows into the drainage trough 90 through the drainage hole 80 at the bottom of the water cooling box 10 together with the water that has not been pumped into the water cooling tank 30 and is discharged outside; (5) After a certain period of water pumping and cooling operation, the ambient temperature and the high-temperature slag temperature in the water cooling box 10 are respectively reduced to certain temperature conditions. At this time, the water pumping operation is stopped, and the hydraulic cylinder 150 is used to open the water cooling cover 40 above the water cooling box 10. After the water cooling tank 30 is left vacant for a certain period of time, the lifting mechanism 170 is used to lift the cooled water cooling tank 30 out of the water cooling box 10.

[0079] The initial temperature of the high-temperature steel slag in the water cooling tank 30 is 400℃~1200℃. The amount of water pumped per ton of high-temperature steel slag is 0.5t~1.5t. After 1h~3h of water pumping and cooling, the ambient temperature in the water cooling box 10 is reduced to less than 70℃. The water cooling cover 40 above the water cooling box 10 is opened, and the water cooling tank 30 is left empty for drainage for 10~30 minutes, and the cooling of the high-temperature steel slag is completed. The water consumption per ton of high-temperature steel slag treated by this process is 0.2t~0.6t. After the process treatment, the high-temperature steel slag is reduced to less than 100℃, the average particle size of the steel slag is 20mm~40mm, and the mass proportion of steel slag above 150mm is less than 20%.

[0080] In summary, the low-cost cooling system for high-temperature solid steel slag provided by the embodiment of the present application can maintain a certain pressure inside the water-cooled box 10 by setting a water seal groove 20, matching the gap between the water-cooled cover 40 and the water seal groove 20, and then adjusting the amount of water in the water seal groove 20. It is not necessary to set up a large number of pressure vessels to maintain the pressure inside the water-cooled box 10, thereby greatly reducing the investment cost. In addition, since a large number of water outlet holes 50 are arranged around the water-cooled tank 30, the high-temperature steel slag in the water-cooled tank 30 can be directly cooled by pumping water, and the water in the water-cooled tank 30 can flow out from the through hole, so that it is not necessary to pour the high-temperature steel slag in the water-cooled tank 30 into the bottom of the water-cooled box 10 and then perform water cooling, which reduces the process of manpower and material resources required to load the cooled high-temperature steel slag into the water-cooled tank 30 after the high-temperature steel slag is cooled, greatly reducing costs and improving efficiency.
