[0034] A first unloading roller 19, which is arranged at the bottom of the first raw material bin 5, a first bracket 7 is fixedly connected between the first raw material bin 5 and the second raw material bin 6, a rotating motor 8 is fixedly connected to the bottom of the first bracket 7, a transmission shaft 9 is fixedly connected to the output end of the rotating motor 8, and a uniform component for uniform unloading is arranged at the bottom of the transmission shaft 9;

[0038] In order to solve the problem that it is inconvenient to proportion the dry quenched coke powder and the coal powder, when the dry quenched coke powder and the coal powder need to be sprayed, the dry quenched coke powder and the coal powder can be placed in the first raw material bin 5 and the second raw material bin 6 respectively, so that the dry quenched coke powder and the coal powder are stored separately, and then the rotating motor 8 is started to drive the uniform component to run.

In the blast furnace, by setting an adjustment component, when it is necessary to adjust the ratio between dry quenching coke powder and coal powder, some components in the uniform component can be taken out and replaced, so as to adapt to different needs. By setting a knocking component, when adding dry quenching coke powder and coal powder, it is convenient to knock the injection shell 1, so that the injection shell 1 vibrates slightly, thereby preventing the dry quenching coke powder and coal powder from sticking to the injection shell 1. By setting a heat dissipation component, when the rotating motor 8 is running, the transmission rod 46 and the fan blades can be driven to rotate, and the wind force can be transmitted to the outer wall of the injection shell 1 through the heat dissipation component, so as to facilitate the heat dissipation treatment of the outside of the injection shell 1.

[0039] Reference Figure 3-4 The uniform component includes a first gear 10, which is fixedly connected to the outer wall of the transmission shaft 9, a transmission belt 11 is meshed on the outer wall of the first gear 10, a second gear 12 is meshed on the other side of the inner wall of the transmission belt 11, a stirring rod 13 is fixedly connected to the center of the second gear 12, the stirring rod 13 is arranged inside the first raw material bin 5, two groups of the second gear 12 are arranged, and two groups of the stirring rod 13 are arranged and symmetrically distributed inside the first raw material bin 5 and the second raw material bin 6, a first bevel gear 14 is fixedly connected to the bottom of the transmission shaft 9, a second bevel gear 15 is meshed on the bottom of the first bevel gear 14, and the second bevel gear 15 A rotating rod 16 is fixedly connected to the center of the rotating rod 16, and a limiting rod 18 is fixedly connected to the outer wall of the rotating rod 16. More than four limiting rods 18 are provided and are circumferentially distributed on the outer wall of the rotating rod 16. One end of the rotating rod 16 is inserted into the inner wall of the first unloading roller 19 through the limiting rod 18, and the other end of the rotating rod 16 is inserted into the second unloading roller 20 through the limiting rod 18. A mounting cylinder 17 is fixedly connected to the top end of the converging tube 4. Two groups of mounting cylinders 17 are provided and are symmetrically distributed at both ends of the converging tube 4. The first unloading roller 19 and the second unloading roller 20 are respectively arranged inside the two groups of mounting cylinders 17, and the surfaces of the first unloading roller 19 and the second unloading roller 20 are provided with unloading grooves.

[0040] When the rotating motor 8 drives the transmission shaft 9 to rotate, it will drive the first gear 10 set on the outer wall of the transmission shaft 9 to rotate, and when the first gear 10 rotates, it will drive the transmission belt 11 to rotate, and when the transmission belt 11 rotates, it will drive the two sets of second gears 12 and the stirring rod 13 to rotate together, so that the dry quenching coke powder and the coal powder in the first raw material bin 5 and the second raw material bin 6 can be stirred by the two sets of stirring rods 13, so that the dry quenching coke powder and the coal powder are stirred in the first raw material bin 5 and the second raw material bin 6 respectively, so that they can be stirred evenly, and the dry quenching coke powder and the coal powder are prevented from long-term accumulation and agglomeration. When the transmission shaft 9 rotates, it will drive the first bevel gear set at the bottom 14 rotates, and when the first bevel gear 14 rotates, it will drive the second bevel gear 15 at the bottom to rotate, and when the second bevel gear 15 rotates, it will drive the rotating rod 16 to rotate, and when the rotating rod 16 rotates, it will drive multiple groups of limiting rods 18 to rotate together, and the limiting rods 18 can drive the first unloading roller 19 and the second unloading roller 20 to rotate in the two groups of mounting cylinders 17 respectively. Since the surfaces of the first unloading roller 19 and the second unloading roller 20 are both provided with unloading grooves, the dry quenching coke powder and the coal powder can fall into the converging pipe 4 through the unloading grooves, and the numbers of unloading grooves on the first unloading roller 19 and the second unloading roller 20 are different, so the dry quenching coke powder and the coal powder can fall according to different proportions.

[0041] Reference Figure 5-7 The adjustment assembly includes a cover plate 21, which is arranged at one end of the mounting tube 17. A first mounting block 22 is fixedly connected to one side of the mounting tube 17. A slot is provided inside the first mounting block 22. A limiting slot is provided at the bottom of the slot. A first spring 24 is fixedly connected to the bottom of the limiting slot. An insert block 25 is fixedly connected to the top of the first spring 24. The insert block 25 extends into the inner wall of the slot. A second mounting block 23 is fixedly connected to one side of the cover plate 21. The push rod 26 is slidably connected to the first spring 24. The inner wall of the second mounting block 23, the arc head 29 is inserted into the inner wall of the slot, the inner wall of the second mounting block 23 is fixedly connected with a fixing plate 27, the outer wall of the push rod 26 is fixedly connected with a limiting plate 28, the end of the push rod 26 away from the arc head 29 extends out of the inner wall of the second mounting block 23, the outer wall of the push rod 26 is slidably connected with a slider 30, the slider 30 is arranged on one side of the arc head 29, the outer wall of the push rod 26 is fixedly connected with a protrusion, and the protrusion is arranged on the side of the slider 30 away from the arc head 29.

[0042] When it is necessary to replace the first feeding roller 19 and the second feeding roller 20, the push rod 26 can be pushed to make the push rod 26 drive the arc head 29, the slider 30, the limiting piece 28 and the protrusion to move to one side. When the slider 30 moves to one side of the plug block 25, since the slider 30 is inclined on both sides, the slider 30 is kept fixed when it moves to the side of the plug block 25 with the cooperation of the protrusion. The plug block 25 can be squeezed downward and retracted into the limiting groove by the inclination set on one side of the plug block 25. When the slider 30 is pushed by the plug block 25, it will retract into the inner wall of the arc head 29 on one side, and then the second mounting block 23 can be pulled. When the second mounting block 23 moves to one side, the plug block can be moved by the inclination of the other side of the slider 30. 25 is squeezed into the limiting groove again, so that the push rod 26 can be moved out of the slot in the first mounting block 22, and the cover plate 21 can be removed from one side of the mounting cylinder 17 at the same time, and the first feeding roller 19 or the second feeding roller 20 can be replaced according to the need of the ratio, and the first feeding roller 19 and the second feeding roller 20 with a suitable number of feeding grooves can be selected and reinstalled in the mounting cylinder 17, and then the end of the push rod 26 with the arc head 29 can be inserted into the slot, and the side of the arc head 29 with the arc surface after passing through the insert block 25 will make the insert block 25 stuck between the arc head 29 and the slider 30, so that the straight side of the arc head 29 faces the block, so that the second mounting block 23 and the cover plate 21 can be firmly installed.

[0043] Reference Figure 5-7 A cover plate 31 is provided on one side of the second mounting block 23, and the cover plate 31 is sleeved on the outer wall of the push rod 26. An arc block 32 is fixedly connected to the top of the cover plate 31, and the arc block 32 is made of iron. A magnet 33 is fixedly connected to the side of the cover plate 21 away from the mounting tube 17, and the magnet 33 is adsorbed on one side of the arc block 32.

[0044] By setting a cover plate 31 on one side of the second mounting block 23, protection can be provided for the outside of the push rod 26 to prevent the push rod 26 from being triggered by external force. By setting a magnet 33 on one side of the cover plate 21, when installing two sets of cover plates 31, it is not convenient to connect the two sets of cover plates 31 through the arc block 32, and the magnet 33 can absorb the iron arc block 32 to facilitate the installation of the two sets of cover plates 31 on the outside of the two sets of second mounting blocks 23.

[0045] Reference Figure 8The knocking assembly includes a third gear 34, the third gear 34 is fixed to the outer wall of the rotating rod 16, a fourth gear 35 is meshed on one side of the third gear 34, a round rod is fixed on one side of the fourth gear 35, a half tooth 36 is fixed on the side of the round rod away from the fourth gear 35, the rack 39 is meshed on one side of the half tooth 36, a second bracket 37 is fixed between the first raw material bin 5 and the second raw material bin 6, a sliding frame 38 is fixed at the center of the second bracket 37, the rack 39 is slidably connected to the inner wall of the sliding frame 38, a ring is sleeved on the outer wall of the round rod, the ring is fixed to one side of the sliding frame 38, a first side plate 41 is fixed on one side of the rack 39, a second spring 42 is fixed to the bottom of the first side plate 41, a second side plate 43 is fixed to the bottom of the second spring 42, and the second side plate 43 is fixed to the inner wall of the sliding frame 38.

[0046] When the rotating rod 16 rotates, the third gear 34 on one side will be driven to rotate, and the third gear 34 will drive the fourth gear 35 meshing with it to rotate when rotating, and the fourth gear 35 can drive the half teeth 36 on one side to rotate in a circle through the round rod. When the toothed side of the half teeth 36 is meshed with the rack 39, the rack 39 will be pushed downward, and the rack 39 will drive the impact block 40 at the bottom to move downward when moving downward. When the impact block 40 hits the top of the injection shell 1, the injection shell 1 will vibrate slightly, so that the dry quenching coke powder and coal powder adhered to the inner wall of the injection shell 1 will be shaken off, so as to prevent the dry quenching coke powder and coal powder from adhering to the inside of the injection shell 1, and when the toothed side of the half teeth 36 passes the rack 39, the second spring 42 at the top of the second side plate 43 will push the first side plate 41 to reset upward, and when the first side plate 41 moves upward, it will drive the rack 39 to reset upward, which is conducive to the next knocking.

[0047] Reference Fig. 9 The heat dissipation assembly includes a fifth gear 44, which is fixedly connected to the outer wall of the transmission shaft 9, a sixth gear 45 is meshed on one side of the fifth gear 44, and the size of the sixth gear 45 is smaller than the fifth gear 44. The transmission rod 46 is fixedly connected to the bottom of the sixth gear 45. A cooling cover 48 is fixedly connected to the outer wall of the injection shell 1, and a transmission pipe 47 is fixedly connected to the top of the cooling cover 48. The fan blades are arranged inside the transmission pipe 47. A hoop 49 is fixedly connected to the top of the cooling cover 48, and the hoop 49 is sleeved on the outer wall of the transmission rod 46. A plurality of air holes 50 are provided at the bottom of the cooling cover 48.

[0048] When the transmission shaft 9 rotates, the fifth gear 44 is driven to rotate, and the fifth gear 44 in turn drives the sixth gear 45 meshed on one side to rotate. Since the size of the fifth gear 44 is larger than the sixth gear 45, when the fifth gear 44 is transmitting to the sixth gear 45, the rotation speed of the sixth gear 45 is greater than that of the fifth gear 44. When the sixth gear 45 rotates, it drives the transmission rod 46 and the fan blades to rotate, thereby generating wind force through the rotation of the fan blades. The wind force generated by the fan blades will be transmitted into the cooling cover 48 through the transmission pipe 47. Since the cooling cover 48 is tightly attached to the outer wall of the spray shell 1, the temperature outside the spray shell 1 can be taken away by the wind force, thereby achieving the effect of cooling the spray shell 1.

[0049] Working principle: In order to solve the problem of inconvenient proportioning of dry quenched coke powder and coal powder, when dry quenched coke powder and coal powder need to be sprayed, the dry quenched coke powder and coal powder can be put into the first raw material bin 5 and the second raw material bin 6 respectively, so that the dry quenched coke powder and coal powder are stored separately, and then the rotating motor 8 is started to drive the first gear 10 arranged on the outer wall of the transmission shaft 9 to rotate, and when the first gear 10 rotates, it will drive the transmission belt 11 to rotate, and when the transmission belt 11 rotates, it will drive the two sets of second gears 12 and the stirring rod 13 to rotate together, so that the dry quenched coke powder and coal powder in the first raw material bin 5 and the second raw material bin 6 can be stirred by the two sets of stirring rods 13, so that the dry quenched coke powder and coal powder are stirred in the first raw material bin 5 and the second raw material bin 6 respectively. It can be stirred evenly to prevent the dry quenching coke powder and coal powder from long-term accumulation and agglomeration. When the transmission shaft 9 rotates, it will drive the first bevel gear 14 set at the bottom to rotate. When the first bevel gear 14 rotates, it will drive the second bevel gear 15 at the bottom to rotate. When the second bevel gear 15 rotates, it will drive the rotating rod 16 to rotate. When the rotating rod 16 rotates, it will drive multiple groups of limiting rods 18 to rotate together. The limiting rod 18 can drive the first unloading roller 19 and the second unloading roller 20 to rotate in the two groups of mounting tubes 17 respectively. Since the surfaces of the first unloading roller 19 and the second unloading roller 20 are both provided with unloading grooves, the dry quenching coke powder and coal powder can fall into the converging pipe 4 through the unloading grooves, and the number of unloading grooves on the first unloading roller 19 and the second unloading roller 20 is The dry quenched coke powder and the coal powder are different, so the dry quenched coke powder and the coal powder can be dropped in different proportions, and the dry quenched coke powder and the coal powder in the converging pipe 4 will fall downward into the injection shell 1, and the dry quenched coke powder and the coal powder will be blown and mixed by the gas blown in from the air inlet pipe 2, and the mixed dry quenched coke powder and the coal powder will be sprayed into the blast furnace from the ejection pipe 3. When it is necessary to adjust the ratio between the dry quenched coke powder and the coal powder, the push rod 26 can be pushed to make the push rod 26 drive the arc head 29, the slider 30, the limiting sheet 28 and the protrusion to move to one side. When the slider 30 moves to one side of the plug block 25, since the two sides of the slider 30 are inclined, the slider 30 is kept fixed when it moves to the side of the plug block 25 under the cooperation of the protrusion, and the plug block 25 can be squeezed downward and retracted into the limit groove by the inclination set on one side of the plug block 25. When the slider 30 is pushed by the insert block 25, it will retract into the inner wall of the arc head 29 on one side, and then the second mounting block 23 can be pulled. When the second mounting block 23 moves to one side, the insert block 25 can be squeezed into the limiting groove again by tilting the other side of the slider 30, so that the push rod 26 can be moved out of the slot in the first mounting block 22, and the cover plate 21 can be removed from one side of the mounting cylinder 17. The first feeding roller 19 or the second feeding roller 20 can be replaced according to the needs of the ratio. The first feeding roller 19 and the second feeding roller 20 with the appropriate number of feeding grooves can be selected and reinstalled in the mounting cylinder 17, and then the end of the push rod 26 with the arc head 29 can be inserted into the slot, and the side with the arc surface of the arc head 29 passes through the insert block 25.The plug block 25 is stuck between the arc head 29 and the slider 30, so that the straight side of the arc head 29 faces the block, so that the second mounting block 23 and the cover plate 21 can be firmly installed. By arranging the cover plate 31 on one side of the second mounting block 23, the outside of the push rod 26 can be protected to prevent the push rod 26 from being triggered by external forces. By arranging the magnet 33 on one side of the cover plate 21, when installing the two sets of cover plates 31, it is not convenient to connect the two sets of cover plates 31 through the arc block 32, and the magnet 33 can absorb the iron arc block 32 to facilitate the two sets of cover plates. The third gear 31 is installed on the outside of the two sets of second mounting blocks 23. When the rotating rod 16 rotates, the third gear 34 on one side is driven to rotate, and the third gear 34 rotates and drives the fourth gear 35 meshing with it to rotate. The fourth gear 35 can drive the half teeth 36 on one side to rotate in a circle through the round rod. When the toothed side of the half teeth 36 meshes with the rack 39, the rack 39 is pushed downward. When the rack 39 moves downward, it drives the impact block 40 at the bottom to move downward. When the impact block 40 hits the top of the injection shell 1, the injection shell 1 is generated. The semi-toothed belt 36 generates slight vibration, thereby shaking off the dry quenching coke powder and coal powder adhering to the inner wall of the injection shell 1, and preventing the dry quenching coke powder and coal powder from adhering to the inside of the injection shell 1. When the toothed side of the semi-toothed belt 36 passes the rack 39, the second spring 42 at the top of the second side plate 43 pushes the first side plate 41 to reset upward, and when the first side plate 41 moves upward, it drives the rack 39 to reset upward, which is beneficial to the next knocking. When the transmission shaft 9 rotates, it drives the fifth gear 44 to rotate, and the fifth gear 44 drives the sixth gear 45 meshed on one side to rotate. The fifth gear 44 is larger than the sixth gear 45, so when the fifth gear 44 is in transmission with the sixth gear 45, the rotation speed of the sixth gear 45 will be greater than that of the fifth gear 44, and the sixth gear 45 will drive the transmission rod 46 and the fan blades to rotate when rotating, thereby generating wind force through the rotation of the fan blades, and the wind force generated by the fan blades will be transmitted into the cooling cover 48 through the transmission pipe 47, and because the cooling cover 48 is closely attached to the outer wall of the spray shell 1, the temperature outside the spray shell 1 can be taken away by wind force, thereby achieving the effect of cooling the spray shell 1.
