[0030] Specifically, when the pulverized coal flows into the connecting pipe 1 402 in the injection box 4 through the conveying pipe 3, a control valve on the connecting pipe 1 402 will open, so that the pulverized coal can flow through the connecting pipe 1 402 to the connecting pipe 2 404 corresponding to the control valve, and then flow to the primary storage box 403 through the connecting pipe 2 404. When the deflection angle of the guide plate 102 exceeds a certain range, so that the difference in the particle size of the pulverized coal before and after the deflection is too large, the connecting pipe 1 402 will open another control valve, so that the pulverized coal of the new particle size will flow to the new primary storage box 403, and then the pulverized coal of different particle sizes will be stored in a graded manner to meet various needs during blast furnace combustion. When the equipment is working, the control valves on the connecting pipe 3 405 and the connecting pipe 4 406 will open, so that the pulverized coal in the primary storage box 403 can flow to the connecting pipe 3 405 through the connecting pipe 4 406, and then the fan 1 414 will be used to make the pulverized coal in the connecting pipe 3 405 The pulverized coal will flow to connecting pipe seven 411, and then flow from connecting pipe seven 411 to regulating box 413 and then flow into the blast furnace through injection port 7 for combustion. When the equipment stops working, some pulverized coal will remain in the regulating box 413. At this time, the control valves at connecting pipe three 405 and connecting pipe four 406 will be closed, and at the same time, a control valve at connecting pipe five 408 and connecting pipe six 409 will be opened, and the air pump 410 starts working, cooperating with the fan one 414 to make the remaining pulverized coal in connecting pipe three 405 and regulating box 413 flow to connecting pipe six 409 through connecting pipe eight 412, and then flow to the secondary storage box 407 through connecting pipe six 409 for storage. When the equipment works again, the control valves at connecting pipe four 406 and connecting pipe three 405 will be opened synchronously with the control valves of the corresponding pulverized coal particle sizes at the primary storage box 403 and connecting pipe three 405, so that the pulverized coal in the secondary storage box 407 can be consumed first.

[0031] See also Figure 3 An opening 423 is provided at one end of the first-level storage box 403 close to the connecting pipe 2 404, and a push plate 421 is slidably connected inside the first-level storage box 403. A gravity sensor is provided on the push plate 421, and an electric telescopic rod 422 is fixedly connected to the lower end of the push plate 421. The electric telescopic rod 422 is fixedly connected to the first-level storage box 403, and an output port 424 is fixedly connected to one side of the first-level storage box 403.

[0032] Specifically, after the classified coal powder flows into the primary storage box 403 through the connecting pipe 2 404, it will be accumulated in the primary storage box 403 under the action of the push plate 421.

When the control valves at the connecting pipe 406 and the connecting pipe 3 405 are opened, the electric telescopic rod 422 will drive the push plate 421 to move, so that the coal powder in the primary storage box 403 can flow to the connecting pipe 3 405 through the output port 424, thereby providing sufficient coal powder for blast furnace combustion.

[0033] See also Figure 4 A partition 419 is fixedly connected to the inside of the regulating box 413, and a reversing valve 1 416 is provided at one end of the partition 419 close to the connecting pipe 7 411, and an input pipe 420 is fixedly connected to the one end of the reversing valve 1 416 close to the connecting pipe 7 411, and the input pipe 420 is fixedly connected to the connecting pipe 7 411, and a reversing valve 2 417 is provided at one end of the partition 419 away from the connecting pipe 7 411, and an output pipe 418 is fixedly connected to the output pipe 418, and the output pipe 418 is fixedly connected to the blowing port 7, and control boxes 415 are provided on both sides of the partition 419, and connecting pipes are connected to both sides of the control box 415, and the connecting pipes are fixedly connected to the reversing valve 1 416 and the reversing valve 2 417 respectively.

After a period of time, the reversing valve one 416 will synchronously reverse, so that the coal powder in the connecting pipe seven 411 will flow to the output pipe 418 through the other control box 415, thereby reducing the content of coal powder of new particle size flowing to the stopped control box 415, thereby providing sufficient time for the coal powder processing in the stopped control box 415.

[0035] See also Figure 5The separator 1 includes a shell 101 fixedly connected to the hot air blower 2, a feed pipe 105 is arranged at the center of the shell 101, the feed pipe 105 is fixedly connected to the feed port 5, and one end of the feed pipe 105 away from the shell 101 is fixedly connected to a protective shell 104, and two openings are arranged on both sides of the protective shell 104, which are respectively fixedly connected to the fan 8 and the conveying pipe 3.

[0036] One end of the protective shell 104 close to the outer shell 101 is fixedly connected to a secondary separation chamber 106, and the secondary separation chamber 106 is fixedly connected to the outer shell 101. An isolation chamber 103 is arranged inside the outer shell 101. The central axis of the isolation chamber 103 coincides with the central axis of the feed pipe 105.

One end of the guide plate 102 away from the feed pipe 105 is fixedly connected to a rotating rod, and both ends of the rotating rod are rotatably connected to the outer shell 101 and the isolation chamber 103.

[0037] Specifically, the injection coal falls from the conveying pipe 3 into the grinder 6 for grinding, and the hot air blower 2 continuously inputs hot air into the grinder 6. The hot air generated by the hot air blower 2 brings the coal powder ground by the grinder 6 into the separator 1. The coal powder floats to the guide plate 102 through the cavity between the outer shell 101 and the isolation chamber 103. Under the action of the guide plate 102, the centrifugal force of the large-sized coal powder is relatively large, and it will directly collide with the feed pipe 105, and then pass through the feed pipe 105 and The cavity between the isolation chambers 103 falls back into the grinder 6, while the coal powder with small particle size has small centrifugal force and will float to the protective shell 104 through the cavity between the feed pipe 105 and the secondary separation chamber 106. The coal powder in the protective shell 104 is sprayed by the fan 8, so that the coal powder in the protective shell 104 flows to the spray box 4 through the conveying pipe 3. At the same time, the angle of the guide plate 102 can be adjusted by rotating the rotating rod. The larger the angle, the stronger the swirl and the finer the screened coal powder.

[0038] Working principle of the present invention: the coal for injection falls from the conveying pipe 3 into the grinder 6 for grinding, and the hot air blower 2 continuously inputs hot air into the grinder 6. The hot air generated by the hot air blower 2 brings the coal powder ground by the grinder 6 into the separator 1, and the coal powder floats to the guide plate 102 through the cavity between the outer shell 101 and the isolation chamber 103. Under the action of the guide plate 102, the centrifugal force of the large-sized coal powder is relatively large, and it will directly collide with the feed pipe 105, and then fall back into the grinder 6 through the cavity between the feed pipe 105 and the isolation chamber 103, while the centrifugal force of the small-sized coal powder is relatively small, and it will float to the protective shell 104 through the cavity between the feed pipe 105 and the secondary separation chamber 106, and then the coal powder in the protective shell 104 will be sifted by the fan 8. The pulverized coal in the protective shell 104 flows into the blowing box 4 through the conveying pipe 3. At the same time, the angle of the guide plate 102 can be adjusted by rotating the rotating rod. The larger the angle, the stronger the swirl and the finer the sieved pulverized coal. When the pulverized coal flows into the connecting pipe 1 402 in the blowing box 4 through the conveying pipe 3, a control valve on the connecting pipe 1 402 will open, so that the pulverized coal can flow into the connecting pipe 2 404 corresponding to the control valve through the connecting pipe 1 402, and then flow into the primary storage box 403 through the connecting pipe 2 404. When the deflection angle of the guide plate 102 exceeds a certain range, so that the difference in the particle size of the pulverized coal before and after the deflection is too large, the connecting pipe 1 402 will open another control valve, so that the pulverized coal of the new particle size will flow into the new primary storage box 403, thereby Coal powder of different particle sizes is stored in grades to meet various needs during blast furnace combustion. After the graded coal powder flows into the primary storage box 403 through the connecting pipe 2 404, it will be accumulated in the primary storage box 403 under the action of the push plate 421. At the same time, the gravity sensor on the push plate 421 will sense the weight. When the weight in the push plate 421 is too heavy, the control valve between the connecting pipe 2 404 and the connecting pipe 1 402 will be controlled to be closed, and the guide plate 102 will be controlled to deflect, so that the coal powder flowing out of the separator 1 can be supplemented with coal powder of other particle sizes. When the control valves at the connecting pipe 406 and the connecting pipe 3 405 are opened, the electric telescopic rod 422 will drive the push plate 421 to move, so that the coal powder in the primary storage box 403 can be transported to the conveyor belt 406. The outlet 424 flows into the connecting pipe three 405 and thus provides sufficient pulverized coal for the blast furnace combustion. When the equipment is working, the control valves on the connecting pipe three 405 and the connecting pipe four 406 will be opened, so that the pulverized coal in the primary storage box 403 can flow to the connecting pipe three 405 through the connecting pipe four 406, and then through the action of the fan one 414, the pulverized coal in the connecting pipe three 405 will flow to the connecting pipe seven 411, and then flow from the connecting pipe seven 411 to the regulating box 413 and then flow to the blast furnace through the injection port 7 for combustion. After the pulverized coal flows to the regulating box 413 through the connecting pipe seven 411, it will flow to one of the control boxes 415 through the input pipe 420, and then flow to the output pipe 418 through the control box 415 and then flow to the injection port 7 to provide pulverized coal for the blast furnace combustion.When the blast furnace needs to change the pulverized coal of different particle sizes, the reversing valve 2 417 will be reversed, so that the remaining pulverized coal can be quickly stored in the control box 415 for preliminary storage, and then flow to the air pump 410 through the connecting pipe 8 412 for subsequent processing, and no longer flow to the blast furnace to affect the combustion of the blast furnace. After a period of time, the reversing valve 1 416 will be synchronously reversed, so that the pulverized coal in the connecting pipe 7 411 will flow to the output pipe 418 through another control box 415, reducing the content of the pulverized coal of the new particle size flowing to the stopped control box 415, providing sufficient time for the pulverized coal processing in the stopped control box 415, and when the equipment stops working, the residual part will be in the regulating box 413. At this time, the control valves at the connecting pipe three 405 and the connecting pipe four 406 will be closed, and at the same time, a control valve at the connecting pipe five 408 and the connecting pipe six 409 will be opened, and the air pump 410 will start to work synchronously, and cooperate with the fan one 414 to make the residual coal powder in the connecting pipe three 405 and the regulating box 413 flow to the connecting pipe six 409 through the connecting pipe eight 412, and then flow to the secondary storage box 407 through the connecting pipe six 409 for storage. When the equipment works again, the control valves at the connecting pipe four 406 and the connecting pipe three 405 will be opened synchronously with the control valves of the corresponding coal powder particle size at the primary storage box 403 and the connecting pipe three 405, so that the coal powder in the secondary storage box 407 can be consumed first.
