[0031] In addition, in the present invention, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0032] For ease of understanding, the principle of smoke and dust in the molten iron tank is explained here. Molten iron discharged from the blast furnace flows into the molten iron tank. Molten iron from the blast furnace flows into the molten iron tank below through the molten iron swing flow trough. The high-temperature and high-speed molten iron produces strong vortices and disturbances on the surrounding air, and reacts with it to generate red smoke and dust containing iron oxide particles. The smoke envelops a large amount of original dust in the tank, and under the combined action of dynamic pressure (rebound force) and hot pressure, it forms a concentrated floating jet that diffuses upward. Corresponding treatment is required.

[0033] The present application is described below with reference to the accompanying drawings and specific embodiments. Figure 1 is a structural schematic diagram of a tin-tapping tank position system in some embodiments or certain embodiments of the present application, Figure 2 This application Figure 1 DD section view of the China Iron water tank at the working position. Figure 3 This application Figure 1 CC section view of the China Iron water tank at the working position, reference Figure 1 to Figure 3 In some embodiments, the embodiments of the present application provide a tin-out tank system, including a tin-out tank 1, a retaining wall 2, a dust removal cover 3, a molten iron tank 4, a dust prevention component 5 and a dust collection component 6.

[0034] The retaining wall 2 is arranged around the iron tank position 1, the dust removal cover 3 is arranged on the top of the retaining wall 2, and forms a channel S with a working position with the retaining wall 2, the iron groove 103 is inserted into the channel S to guide the molten iron to the iron tank 4 at the working position, the dust prevention component 5 is arranged to be liftable relative to the retaining wall 2 so that its bottom is higher or lower than the opening 41 of the iron tank 4, the dust prevention component 5 extends from one retaining wall 2 to the adjacent retaining wall 2, and the dust suction component 6 is inserted into the channel S to extract the smoke and dust in the channel S.

[0035] In the iron-outlet tank position system, a retaining wall 2 is arranged around the iron-outlet tank position 1, and a dust-removing cover plate 3 is arranged on the retaining wall 2. A channel S with a working position can be formed between the dust-removing cover plate 3 and the retaining wall 2, and the molten iron tank 4 can receive the molten iron in the iron groove 103 inserted into the channel S at the working position. For the large amount of smoke generated by the molten iron tank 4 in the process of receiving the molten iron, the anti-dust component 5 can be raised and lowered relative to the retaining wall 2 so that its bottom is higher or lower than the opening 41 of the molten iron tank 4, and the anti-dust component 5 extends from one retaining wall 2 to the adjacent retaining wall 2. When the anti-dust component 5 is lower than the opening 41 of the molten iron tank 4, the surrounding retaining wall 2, the dust-removing cover plate 3 and the anti-dust component 5 can close the space above the molten iron tank 4, and limit the smoke generated by the molten iron tank 4 receiving the molten iron to the channel S, and then extract and process it through the dust suction component 6 inserted into the channel S. The smoke generated when the molten iron tank 4 receives molten iron can be sealed in the channel S for effective extraction and treatment, which can reduce the amount of smoke dissipated into the environment and improve the environmental protection effect of the iron-outlet tank position system. The technical problem that the environmental protection effect of the iron-outlet tank position 1 is not ideal can be solved. Moreover, when the anti-dust component 5 is higher than the opening 41 of the molten iron tank 4, the anti-dust component 5 will not affect the movement and other operations of the molten iron tank 4, and can also improve the working efficiency of the iron-outlet tank position system.

[0036] It should be noted that the iron-discharging tank position 1 refers to the parking position of the iron-discharging tank that receives the molten iron during the iron-discharging process of the blast furnace, and the retaining wall 2 can be set on the civil structure beam above the opening 41 of the iron-discharging tank 4 and set around the iron-discharging tank position 1. Figure 2 and Figure 3 In the figure, the state of the anti-dust component 5 being lower than the opening 41 of the molten iron tank 4 is shown. At this time, the space between the top of the molten iron tank 4 and the dust removal cover plate 3 is nearly closed, which can effectively reduce the pollution caused by smoke escaping from the channel S and improve the environmental protection effect of the iron tank position system. The working position can be a certain point on the iron tank position 1 that needs to receive the molten iron.

[0037] For ease of understanding, here is provided Figure 4 and Figure 5 , Figure 4 This application Figure 1 FF section view of the non-working position. Figure 5 This application Figure 1 EE section view of the non-working position. Figure 4 and Figure 5 Indicated in Figure 1 A cross-sectional view of another state of the iron tank position system is shown in the figure. At this time, the height of the anti-dust assembly 5 is higher than the opening 41 of the molten iron tank 4. The molten iron tank 4 can move from the bottom of the anti-dust assembly 5 through the channel S or perform other operations, which is beneficial to ensure the working efficiency of the iron tank position system.

[0038] It should be noted that Figure 2The cross-sectional position in the middle DD direction is Figure 4 The cross-sectional position in the middle FF direction is the same. Figure 3 The cross-sectional position in the CC direction is Figure 5 The cross-sectional position in the EE direction is the same, so Figure 1 Use the letters in brackets to distinguish DD from FF, and the same applies to CC from EE.

[0039] In some embodiments, the iron tapping tank system further includes an air curtain assembly 7 connected to the anti-dust assembly 5, and the air curtain assembly 7 is used to promote the flow of smoke toward the dust collection component.

[0040] The air curtain assembly 7 can promote the flow of smoke into the dust collecting component, further reduce the possibility of smoke escaping into the environment on the basis of the anti-dust assembly 5, and improve the environmental protection effect of the iron tank position system. In addition, the air curtain assembly 7 is connected to the anti-dust assembly 5, which can also reduce the space required by the air curtain assembly 7. The air curtain assembly 7 can be raised and lowered together with the anti-dust assembly 5 to reduce interference, and promote the smoke to be extracted by the dust collecting component when the molten iron tank 4 is in the working position.

[0041] In some embodiments, the air curtain assembly 7 includes a nozzle 71 , a pipe 72 and a carrier 73 for carrying a medium. The nozzle 71 is connected to the anti-dust assembly 5 and faces upwards to the molten iron ladle 4 . The pipe 72 connects the carrier 73 and the nozzle 71 .

[0042] The carrier 73 in the air curtain assembly 7 can supply the medium, and the medium enters the nozzle 71 through the pipe 72, and then the smoke flowing out of the opening 41 of the molten iron tank 4 moves upward through the nozzle 71, which is beneficial for the smoke to enter the dust collection part. The medium sprayed from the nozzle 71 can also react with the smoke and purify the smoke, which is also beneficial to improving the environmental protection effect of the iron tank position system.

[0043] In some embodiments, the carrier 73 may be a gas cylinder or a water tank or other structure, and the medium carried in the carrier 73 may be cooling water, etc. After being sprayed out by the nozzle 71, a high-speed water mist jet is formed, which has a better purification effect and can also reduce the temperature in the channel S, thereby ensuring the stable operation of the iron tank position 1.

[0044] In some embodiments, the pipeline 72 may include a metal hose section 721 and a medium pipeline section 722, the metal hose section 721 connects the carrier 73 and the medium pipeline section 722, the medium pipeline section 722 is further connected to the nozzle 71, and the length of the metal hose section 721 is greater than the length of the medium pipeline section 722. This is beneficial to increase the service life of the air curtain assembly 7, reduce losses, and improve the environmental protection effect of the iron tapping tank system.

[0045] In some embodiments, a plurality of nozzles 71 are arranged at intervals in the dust prevention assembly 5 along the arrangement direction of the retaining wall 2. The effect of promoting airflow and purifying the environment in the channel S is good, which is conducive to improving the environmental protection effect of the iron tank position system. The dust prevention assembly 5 and the air curtain assembly 7 can effectively control the flow direction of the flue gas flow to avoid the overflow of smoke and dust caused by excessive short-term flue gas volume or lateral wind; at the same time, it does not affect the movement of the molten iron tank 4 car and the normal operation of the swing chute.

[0046] In some embodiments, the air curtain assembly 7 may also only include a nozzle or other structural parts other than the nozzle 71 inserted into the retaining wall 2 and extending into the channel S. This application does not impose any limitation on this.

[0047] In some embodiments, the anti-dust assembly 5 may include: at least two anti-dust curtains 51 that are both escalable relative to the retaining wall 2.

It is easy to operate, can effectively reduce the dispersion of smoke and dust, and can effectively improve the environmental performance of the iron tank position system.

[0048] In some embodiments, the anti-dust curtains 51 are all complete curtains, and when the bottom of each anti-dust curtain 51 drops below the opening 41 of the molten iron tank 4, the anti-dust curtain 51 can cover the space above the molten iron tank 4 at one end of the corresponding channel S, and in the direction of the extension of the channel S, the anti-dust curtain 51 is in contact with one end of the dust removal cover plate 3 and one side of the two retaining walls 2. It can improve the limiting effect of smoke and dust, reduce the possibility of smoke and dust escaping, and improve the environmental protection effect of the iron tank position system.

[0049] In some embodiments, the anti-dust curtain 51 includes a steel frame 511 and a fireproof cloth 512 laid on the steel frame 511. The anti-dust curtain 51 can improve the effect of preventing smoke and dust from escaping in a high temperature environment, thereby improving the environmental protection effect of the iron tank system.

[0050] In some embodiments, the steel frame 511 may be a steel structure frame, and the thickness of the steel structure frame is not less than 5 mm. This is beneficial to prolonging the service life of the anti-dust curtain 51, and the steel frame 511 and the fireproof cloth 512 can be spliced ​​together. This reduces loss and waste, and is also beneficial to improving the environmental protection effect of the iron tank position system.

[0053] In some embodiments, the iron-outlet tank position system further includes an intermediate partition wall 9 and a molten iron swing flow trough 10. The intermediate partition wall 9 is arranged in the corresponding channel S and is lower than the retaining wall 2. The channel S is provided with working positions on both sides of the intermediate partition wall 9. The molten iron swing flow trough 10 is swingably arranged on the top of the intermediate partition wall 9. The molten iron swing flow trough 10 receives the molten iron from the iron ditch 103, and the two ends are respectively used to guide the molten iron into the molten iron tank 4 located at the corresponding working position.

[0054] In some embodiments, two working positions can be arranged on both sides of the middle isolation wall 9, the iron groove 103 can be inserted into the channel S along the extension direction of the channel S, and the iron groove 103 can be supported on the support 102 or supported on the shell of the blast furnace (not shown in the figure), so as to guide the molten iron discharged from the blast furnace into the molten iron swing flow channel 10.
