[0039] In an ore sintering experimental device provided by an embodiment of the present disclosure, the combustion part can perform combustion heating, and the smoke and hot air burned in the combustion part can heat the heat storage chamber 100, and the combustion parts are two respectively arranged on both sides of the heat storage chamber 100, and the combustion heat is increased by the combustion parts on both sides, and the heat is supplied simultaneously by the combustion parts on both sides, so that the heat storage chamber 100 can be heated together by the combustion parts on both sides, so that the heat storage chamber 100 can be fully heated, and the hot air enters the heat storage chamber 100 from both sides, and the hot air then enters the sintering furnace 203 from the heat storage chamber 100, and the heat storage chamber 10 The lower part of the heat storage chamber 100 is provided with a sealing sleeve 101, which is connected to the inside of the heat storage chamber 100. The sealing sleeve 101 is inserted between the first sealing cylinder 201 and the sintering furnace 203. The sealing between the sealing sleeve 101 and the sintering furnace 203 allows the hot air in the heat storage chamber 100 to enter the sintering furnace 203 after the sintering furnace 203 is connected to the sealing sleeve 101. In this way, the ore powder in the sintering furnace 203 can be heated and sintered. The sintering box 200 is movably arranged at the bottom of the heat storage chamber 100. The sintering box 200 and the heat storage chamber 100 are movably connected. By moving the sintering box 200, the sintering box 200 can be In order to facilitate the placement and removal of materials in the sintering furnace 203, the heat exchange flue 202 in the sintering box 200 can discharge the flue gas entering the sintering furnace 203. Liquid is injected between the heat exchange flue 202 and the sintering box 200 to exchange heat with the heat exchange flue 202, and the flue gas discharged from the sintering furnace 203 can be cooled to prevent the temperature discharged from the sintering furnace 203 from being too high. The liquid in the sintering box 200 enters between the first sealing cylinder 201 and the sintering furnace 203, and the sealing sleeve 101 can be inserted into the liquid between the first sealing cylinder 201 and the sintering furnace 203. Through the liquid, The sintering furnace 203 is sealedly connected to the sealing sleeve 101, which can prevent the flue gas and hot air in the sintering furnace 203 from being discharged from between the sintering furnace 203 and the sealing sleeve 101. One end of the heat exchange flue 202 is connected to the sintering furnace 203 to absorb the flue gas in the sintering furnace 203, and the other end of the heat exchange flue 202 extends out of the sintering box 200 to discharge the flue gas. The trolley 300 at the bottom of the sintering box 200 can drive the sintering box 200 to move at the bottom of the heat storage chamber 100, and the sintering box 200 can be raised and lowered on the trolley 300, which can facilitate the connection between the sintering furnace 203 and the sealing sleeve 101.

[0040] Combination Figure 1-2As shown, preferably, the combustion part includes: two combustion furnaces, which are divided into furnace A 501 and furnace B 502, which are respectively arranged on both sides of the heat storage chamber 100, and the combustion furnace is connected to the heat storage chamber 100; two gas pipelines 600, which are respectively connected to the furnace A 501 and the furnace B 502, and the two gas pipelines 600 are respectively provided with a gas valve 601; two blast pipelines 602, which are respectively connected to the furnace A 501 and the furnace B 502, and the two blast pipelines 602 are respectively provided with a blast valve 603; three induced draft pipelines 604, two of which are respectively connected to the furnace A 501 and the furnace B 502, and the other one can be connected to the heat exchange flue 202, and the three induced draft pipelines 604 are respectively provided with induced draft valves 605.

[0041] In this way, the combustion part is composed of two combustion furnaces, and the two combustion furnaces are divided into A furnace 501 and B furnace 502. Furnace A 501 and furnace B 502 are respectively connected with gas pipelines 600, and the gas pipelines 600 can be connected to the upper part of the combustion furnaces to supply gas to the combustion furnaces so that the combustion furnaces can burn. Furnace A 501 and furnace B 502 are respectively connected with blast ducts 602, and the blast ducts 602 can supply gas to furnace A 501 and furnace B 502, thereby increasing the air in furnace A 501 and furnace B 502, so that furnace A 501 and furnace B 502 can burn better. The bottom of furnace A 501 and furnace B 502 are respectively connected with induced draft ducts 604, and There are three induced draft ducts 604, and another one can be connected to the heat exchange flue 202. The flue gas in the combustion furnace can be extracted and discharged through the heat exchange flue 202. The induced draft duct 604 is connected to an induced draft fan, which can extract the induced draft duct 604 to facilitate the extraction of flue gas. Gas valves 601 are respectively installed on the gas pipeline 600, and the gas intake of gas can be controlled by the gas valve 601. Blower valves 603 are respectively installed on the blast duct 602, and the air intake can be respectively controlled by the blast valve 603. Induction valves 605 are respectively installed on the induced draft duct 604, and the extraction of flue gas from the induced draft duct 604 can be controlled by the induced draft valve 605.

[0042] The heat storage chamber 100 can be heated by hot air and flue gas through the two combustion furnaces.

[0043] Combination Figure 3-4As shown, preferably, a second sealing cylinder 204 is opened on the other side of the upper part of the sintering box 200, and the second sealing cylinder 204 is flush with the first sealing cylinder 201 in height, and the first sealing cylinder 204 is connected to the second sealing cylinder 204 through the sintering box 200; and a sealing platform 205 is provided in the second sealing cylinder 204, and the height of the sealing platform 205 is flush with the upper height of the second sealing cylinder 204; a circulating water tank 206 is provided on the upper part of the sintering box 200, and a circulating water pump 207 is provided in the circulating water tank 206, and the circulating water pump 207 is connected to the first sealing cylinder 201; a return water tank 208 is provided on the side wall of the second sealing cylinder 204, an overflow port 209 is provided between the second sealing cylinder 204 and the return water tank 208, and the return water tank 208 is connected to the circulating water tank 206.

[0044] In this way, a second sealing cylinder 204 is arranged on the other side of the upper part of the sintering box 200, and the height of the second sealing cylinder 204 is the same as that of the first sealing cylinder 201, so that the liquid can be prevented from flowing out of the lower sealing cylinder when the heights of the second sealing cylinder 204 and the first sealing cylinder 201 are different, and the first sealing cylinder 201 and the second sealing cylinder 204 are connected through the sintering box 200, and a sealing platform 205 is installed in the second sealing cylinder 204, and a gap is formed between the second sealing cylinder 204 and the sealing platform 205, and the gap is filled with liquid. When preheating, the sealing sleeve 101 can be inserted into the liquid between the second sealing cylinder 204 and the sealing platform 205, so that the heat storage chamber 100 can be sealed and preheated, and the height of the sealing platform 205 is flush with the upper part of the second sealing cylinder 204, and a circulating water tank 206 is also installed on the sintering box 200, and the circulating water tank 206 can store liquid, so that the water in the sintering box 200 can be circulated. Thereby, it plays a role in cooling the heat exchange flue 202. A return water tank 208 is arranged on the outer side of the second sealing cylinder 204. The second seal discharges water into the return water tank 208 through the overflow port 209 between the second seal and the return water tank 208. Then the circulating water pump 207 in the circulating water tank 206 circulates water to the sintering box 200, and the water flowing out of the return water tank 208 can flow back into the circulating water tank 206. The circulating water pump 207 is connected to the first sealing cylinder 201, and the circulating water pump 207 supplies water to the first sealing cylinder 201. The water in the first sealing cylinder 201 is connected with the second sealing cylinder 204 through the sintering box 200, so that the water surface in the first sealing cylinder 201 and the second sealing cylinder 204 can be flush, so that the water in the first sealing cylinder 201 and the second sealing cylinder 204 can be prevented from evaporating due to heating, resulting in a reduction of water. In addition, due to the circulation of water, the heat exchange flue 202 can be circulated for heat exchange to prevent the temperature of the heat exchange flue 202 from being too high.

[0045] Combination Figure 1 and 3-4, preferably, the lifting device includes: four lifting wheels 401, which are fixedly arranged on two sides of the trolley 300 respectively; a lifting frame 402, which is fixedly arranged on both sides of the sintering box 200, and the lifting frame 402 is matched with the lifting wheel 401; a limit part 403, which is fixedly arranged on both sides of the bottom of the heat storage chamber 100; baffles 404, which are two groups, one group of two, one group of baffles 404 is fixedly arranged on one side of the sintering box 200, and the limit part 403 is arranged between the two baffles 404, and the two groups of baffles 404 are respectively arranged on both sides of the sintering box 200; a track 405, which is arranged at the bottom of the trolley 300, and the trolley 300 is slidably arranged on the track 405; a limit switch 406, which is fixedly arranged on both sides of the track 405, and the limit switch 406 is arranged on the track 405 on both sides of the trolley 300.

[0046] In this way, the lifting wheels 401 arranged on both sides of the trolley 300 can play the role of supporting the lifting frame 402. The lifting frame 402 is slidably arranged on the lifting wheels 401. The sintering box 200 slides on the lifting wheels 401 through the lifting frames 402 on both sides. When preheating is performed, the trolley 300 moves to the side of the sintering box 200 with the sintering furnace 203, so that the sealing platform 205 is aligned and connected with the heat storage chamber 100. When the sealing platform 205 moves to the bottom of the heat storage chamber 100, the sintering box 200 rises, so that the sealing platform 205 is connected with the sealing sleeve 101 at the bottom of the heat storage chamber 100. The lifting frame 402 is an inverted V-shaped structure. When the trolley 300 drives the sintering box 200 to move When the sealing platform 205 and the sealing sleeve 101 are on the same central axis line, the baffle 404 on one side of the sealing platform 205 contacts the limiting part 403, and the limiting part 403 blocks the movement of the sintering box 200. Since the sintering box 200 is not subjected to force on the side of the trolley 300, the middle part of the lifting frame 402 is pressed on the lifting wheel 401. When the trolley 300 continues to move forward, the sintering box 200 is subjected to a blocking force, which causes the lifting wheel 401 to slide in the lifting frame 402. Since the two ends of the lifting frame 402 are respectively inclined downward, when the lifting frame 402 moves on the lifting wheel 401, the sintering furnace 203 is lifted, so that the sealing sleeve 101 can be inserted into the second sealing cylinder 204. The trolley 300 is placed on the sealing platform 205. When the sintering furnace 203 is raised to a suitable position, the trolley 300 touches the limit switch 406 on the track 405, and the trolley 300 stops moving, which can prevent the lifting frame 402 from being separated from the lifting wheel 401. The track 405 can make the trolley 300 slide smoothly to prevent vibration during movement. In this way, the heat storage chamber 100 can be sealed when it is preheated. After the preheating is completed, the trolley 300 moves in the opposite direction. Since the lifting frame 402 is tilted, the baffle 404 will still be pressed on the limit portion 403. When the trolley 300 moves, the lifting frame 402 on the side of the sintering box 200 will move when the lifting wheel 401 moves. The sintering box 200 is made to fall. When the sintering box 200 falls completely, the sintering box 200 will move with the trolley 300. The trolley 300 continues to move. After the sintering box 200 falls completely, the baffle 404 will be separated from the limiting part 403. The baffle 404 on the side of the sintering furnace 203 will lean against the limiting part 403. The trolley 300 continues to move to the limit switch 406 on the other side. Through the restriction of the baffle 404 by the limiting part 403, the sintering box 200 can be lifted up under the push of the trolley 300, so that the sealing sleeve 101 can be inserted into the liquid between the first sealing tube 201 and the sintering furnace 203 for sealing, thereby preventing gas leakage during ore sintering.

[0047] Combination Figure 1 As shown, preferably, an explosion-proof sealing valve is provided on the upper portion of the heat storage chamber 100 , and the explosion-proof sealing valve is in communication with the heat storage chamber 100 .

[0048] In this way, by installing an explosion-proof sealing valve in the heat storage chamber 100, the pressure in the heat storage chamber 100 can be prevented from increasing, and the pressure in the heat storage chamber 100 can be stabilized. In addition, the depth of the explosion-proof sealing valve inserted into the liquid is less than the depth of the sealing sleeve 101 inserted into the liquid, thereby preventing the high-pressure gas from being discharged from the sealing sleeve 101, thereby facilitating the high-pressure gas to be discharged from the explosion-proof sealing valve.

[0049] Combination Figure 6 As shown, preferably, the combustion furnace comprises: furnace A 501 and furnace B 502 , an air-permeable partition 503 is provided at the bottom of the combustion furnace, and heat storage stones 504 are provided on the upper part of the partition 503 .

[0050] In this way, the combustion furnace is divided into two furnaces A 501 and B 502. The partition 503 installed on the inner side of the bottom of the combustion furnace can support the heat storage stone 504 in the combustion furnace, so that a cavity can be formed at the bottom of the combustion furnace, which can facilitate the circulation of flue gas and air. During preheating, the flue gas will pass through the heat storage stone 504, and the flue gas can heat the heat storage stone 504, and the heat storage stone 504 can also cool the flue gas. When the heat storage stone 504 is heated and the ore is sintered, air enters from the bottom of the combustion furnace and flows through the heat storage stone 504. The heat storage stone 504 can heat the air. The heated air can directly supply gas combustion, which can increase the temperature generated by gas combustion.

[0051] Preferably, the liquid in the sintering box 200 is water, and the height of the liquid is flush with the height of the overflow port 209 .

[0052] In this way, the liquid in the sintering box 200 is water and can be easily replaced, and the height of the liquid can be controlled through the overflow port 209, so that the liquid level in the first sealing cylinder 201 and the second sealing cylinder 204 can be flush.

[0053] Combination Figure 3-4 As shown, preferably, a rubber connecting sleeve 210 is provided at one end of the heat exchange flue 202 extending out of the sintering box 200 , the opening of the rubber connecting sleeve 210 faces upward, and the rubber connecting sleeve 210 can be connected to the induced draft duct 604 .

[0054] In this way, a rubber connecting sleeve 210 is provided on the heat exchange flue 202 extending out of the sintering box 200, and the opening of the rubber connecting sleeve 210 is upward, and the opening of the induced draft duct 604 is downward. When the rubber connecting sleeve 210 rises, it can be pressed on the induced draft duct 604, so that the induced draft duct 604 can be tightly connected with the rubber connecting sleeve 210, which makes it convenient for the induced draft duct 604 to extract the flue gas in the heat exchange duct.

[0055] Combination Figure 5-6As shown, preferably, the interior of the heat storage chamber 100 is hollow, and an air duct 102 is provided on the inner side of the bottom of the heat storage chamber 100 , and the air duct 102 is communicated with the sealing sleeve 101 .

[0056] In this way, the heat storage chamber 100 is hollow, which can facilitate the mixing of hot air in the combustion furnaces on both sides so as to facilitate the entry into the sintering furnace 203. In addition, there is an air duct 102 extending upward from the bottom of the heat storage chamber 100. The air duct 102 can prevent the flame in the combustion furnace from directly entering the sealed connecting sleeve. In addition, by separately arranging the heat storage chamber 100, it is convenient to adjust and monitor the temperature output in the heat storage chamber 100, so as to prevent the flame from directly entering the sintering furnace 203, causing the problem that the sintering temperature cannot be controlled.

[0057] Combination Figure 7 As shown, preferably, the lifting frame 402 is an inverted V-shaped structure with a groove on one side, and the lifting wheel 401 is slidably disposed in the groove of the lifting frame 402 .

[0058] When the lifting frame 402 is set to an inverted V shape, the lifting frame 402 will drop under the action of gravity, and the highest bent part of the lifting frame 402 will be pressed on the lifting pulley. At this time, the sintering box 200 is at the lowest position. When the baffle plate 404 on the side of the sintering box 200 is blocked by the limiting part 403, the sintering box 200 stops moving, and the trolley 300 drives the lifting pulley to continue moving. At this time, the lifting pulley will move to one side of the lifting frame 402. Since the side of the V-shaped lifting frame 402 extends downward at an angle, when the height of the lifting wheel 401 remains unchanged, the lifting frame 402 will be pushed up by the lifting wheel 401, thereby driving the sintering box 200 to rise through the rise of the lifting frame 402, thereby achieving a sealing effect between the sintering box 200 and the heat storage chamber 100.

[0059] How to use the ore sintering experimental device:

[0060] Preheating: through the sealing connection between the second sealing cylinder 204 and the sealing sleeve 101, the A furnace 501 starts to burn, and the B furnace 502 does not burn and smoke is sucked. The smoke and hot air from the A furnace 501 enter the B furnace 502 through the regenerator 100, heat the regenerator 100 and the heat storage stone 504 in the B furnace 502, and then are discharged from the B furnace 502;

[0061] The B furnace 502 starts to burn, and the A furnace 501 is closed. The smoke and hot air from the B furnace 502 enter the A furnace 501 from the regenerator 100, heat the regenerator 100 and the heat storage stones 504 in the A furnace 501, and then are discharged from the A furnace 501. The temperature of the smoke discharged from the regenerator 100 can be reduced by filtering the heat storage stones 504.

[0062] When furnace A 501 is burning, the gas pipeline 600 and the blast pipeline 602 connected to furnace A 501 are opened, and only the induced draft pipeline 604 connected to furnace B 502 is opened, and the gas pipeline 600 and the blast pipeline 602 connected to furnace B 502 are closed;

[0063] When the B furnace 502 is burning, the gas pipeline 600 and the blast pipeline 602 connected to the B furnace 502 are opened, and only the induced draft pipeline 604 connected to the A furnace 501 is opened, and the gas pipeline 600 and the blast pipeline 602 connected to the B furnace 502 are closed;

[0064] The A furnace 501 and the B furnace 502 are alternately ignited and burned to heat the regenerator 100 and the regenerator stones 504 in the A furnace 501 and the B furnace 502;

[0065] Sintering: The first sealing cylinder 201 is sealed and connected with the sealing sleeve 101, the sintering furnace 203 is connected with the heat storage chamber 100, the A furnace 501 and the B furnace 502 are started at the same time, and the air flows through the heat storage stone 504, and the heat storage stone 504 preheats the air; the air enters the A furnace 501 and the B furnace 502 for combustion, the flue gas and hot air enter the heat storage chamber 100, and then enter the sintering furnace 203 from the heat storage chamber 100 for heating and sintering, and the hot air after sintering is discharged from the heat exchange pipe, and the liquid in the sintering box 200 can cool the flue gas and hot air. When the sintering box 200 rises, the rubber connecting sleeve 210 on the heat exchange flue 202 is sealedly connected with the induced draft duct 604, so that the induced draft duct 604 can extract the flue gas in the heat exchange flue 202, reduce the pressure in the heat storage chamber 100, and transport the flue gas to the dust removal equipment for dust removal before discharge.
