Description

Technical Field

[0001] This utility model relates to the field of sintering machine technology, and in particular to a sintering fuel mixing and blending device. Background Technology

[0002] In conventional sintering processes, the one-time input of fuel often results in fine mineral powder adhering to the surface of solid fuel or mixing with it to form a spherical structure, which in turn hinders the effective combustion of fuel particles. Therefore, to improve this problem, it is necessary to mix some fuel with the sintering mixture and participate in the granulation process together.

[0003] The existing equipment includes a coke powder feeding device for sintering machines and a rake tooth loosening device for sintering machines. The coke powder feeding device for sintering machines mainly relies on the feeding trough under the screw conveyor for fuel laying. However, this structure has limitations in the precise control of the feeding weight and cannot achieve the ideal control effect.

[0004] On the other hand, the existing sintering machine rake tooth loosening device achieves loosening and mixing through the reciprocating motion of a multi-axis crank arm. However, this structural design has many moving joints and there is a lot of dust in the sintering environment, which may lead to a high failure rate. In addition, it can only stir in one direction and cannot achieve the ideal mixing effect.

[0005] Therefore, it is necessary to propose a sintering fuel mixing device to solve or at least alleviate the above-mentioned defects. Utility Model Content

[0033] Please see the appendix Figure 1-3 The present invention provides a sintering fuel mixing and blending device in one embodiment, comprising a silo 10 and a screw feeder 20, a spreading mechanism 30, and a blending mechanism 40 built into the silo 10. Details are as follows:

[0034] The top of the silo 10 is provided with a feed inlet 110. The screw feeding mechanism 20 is connected to the top of the silo 10 and is rotatably arranged. The feed inlet 110 is connected to the screw feeding mechanism 20. The bottom of the screw feeding mechanism 20 is provided with a feeding channel 211. The spreading mechanism 30 is connected to the middle of the silo 10 and is rotatably arranged. The spreading mechanism 30 has a plurality of metering grooves 311 units arranged side by side along its own axis. Each metering groove 311 unit includes a plurality of metering grooves 311 arranged at intervals along the circumference of the spreading mechanism 30. The mixing mechanism 40 is connected to the bottom of the silo 10 and is rotatably arranged. The top of the mixing mechanism 40 is provided with a feed channel 411.

[0035] Specifically, the sintering fuel addition and mixing device in this application includes a silo 10 and a screw feeding mechanism 20, a spreading mechanism 30 and a mixing mechanism 40 built into the silo 10. The silo 10 serves as the storage chamber of the entire device. After the feed inlet 110 is set at its top, the fuel enters from the feed inlet 110 and then passes through the screw feeding mechanism 20, the spreading mechanism 30 and the mixing mechanism 40 arranged from top to bottom in sequence to complete the entire feeding, spreading and mixing process.

[0036] Fuel enters the hopper 10 through the inlet 110 and is first fed by the screw feeder 20. The screw feeder 20 utilizes its screw output to push the fuel forward axially, ensuring stable delivery across the full width of the trolley. The feeding channel 211 at the bottom of the screw feeder 20 simultaneously discharges fuel during transport, which gradually falls onto the spreading mechanism 30 located in the middle of the hopper 10. The spreading mechanism 30 has multiple metering grooves 311 arranged side-by-side along its axial direction, ensuring that each width range has a metering groove 311 unit. Each metering groove 311 unit includes multiple metering grooves 311 spaced circumferentially along the spreading mechanism 30, so that the metering grooves 311 rotate with the mechanism as it rotates. After the fuel is collected at the top, it is rotated to the bottom for spreading. Since the size of each metering trough 311 is consistent and quantitative, the fuel falling downward within each width range under the uniform rotation of the spreading mechanism 30 is also uniform. In a preferred embodiment of this application, the cross-section of the metering trough 311 can be long and narrow, so that the length, width and height of each metering trough 311 are consistent to ensure quantitative spreading. Finally, the fuel is mixed and stirred by the bottom mixing mechanism 40 so that the fuel is evenly coated on the surface of the mixed particles, thereby achieving the effect of uniform fuel distribution and efficient mixing. Therefore, a feeding channel 411 needs to be opened at the top of the mixing mechanism 40 so that the quantitative fuel falling through the metering trough 311 can smoothly enter the mixing mechanism 40 and be repeatedly stirred and mixed with the sintered ore already distributed in the mixing mechanism 40.

[0037] In a preferred embodiment of the present invention, the spiral feeding mechanism 20 includes a first cylinder 210, a first rotating shaft 220, a spiral blade 230, a first driving assembly 240, and two first bearing seats 250. The first cylinder 210 is connected to the top of the hopper 10, and the feeding channel 211 is provided at the bottom of the first cylinder 210. The two first bearing seats 250 are connected to the top two ends of the hopper 10. The two ends of the first rotating shaft 220 extend out of the first cylinder 210 and are rotatably connected to the first bearing seats 250. The spiral blade 230 is mounted on the first rotating shaft 220. The driving end of the first driving assembly 240 is connected to one end of the first rotating shaft 220.

[0038] It should be noted that by rotating the first rotating shaft 220 to drive the spiral blades 230 to rotate, the fuel is conveyed forward along with the spiral blades 230, thereby ensuring that the fuel is stably delivered to the full width of the trolley. The first bearing seat 250 is used to rotatably mount the first rotating shaft 220, and the first driving assembly 240 drives the first rotating shaft 220 to rotate.

[0039] In a preferred embodiment of the present invention, the material spreading mechanism 30 divides the hopper 10 into an upper storage space 120 and a lower storage space 130, and the bottom side wall of the upper storage space 120 of the hopper 10 is inclined downward.

[0040] It is important to note that the fuel must fall onto the spreading mechanism 30 after coming down from the screw feeder 20. Therefore, the spreading mechanism 30 forms a closed cavity in the upper part of the silo 10, meaning there is no gap between the spreading mechanism 30 and the side wall of the silo 10. This allows the spreading mechanism 30 to divide the silo 10 into an upper storage space 120 and a lower storage space 130. The upper storage space 120 is used to accumulate fuel from the screw feeder 20 to the spreading mechanism 30, while the lower storage space 130 is used for the fuel in the metering tank 311 of the spreading mechanism 30 to fall into the mixing mechanism 40. The bottom side wall of the upper storage space 120 of the silo 10 is inclined downwards to ensure that if the fuel feeding speed is insufficient and causes accumulation, it can slide downwards under the action of gravity through the inclined wall.

[0041] In a preferred embodiment of the present invention, the material spreading mechanism 30 includes a roller 310, a second drive assembly 320, and two second bearing seats 330. The two second bearing seats 330 are connected to each other at the two ends of the middle part of the hopper 10. The two ends of the roller 310 extend out of the hopper 10 and are rotatably connected to the second bearing seats 330. The roller 310 is provided with the metering groove 311. The drive end of the second drive assembly 320 is connected to one end of the roller 310.

[0042] It is worth noting that the roller 310 has metering grooves 311, and its rotation drives all the metering grooves 311 to rotate. The second bearing seat 330 is used to rotatably connect the two ends of the roller 310. The roller 310 is driven to rotate by the second drive assembly 320. Fuel enters the metering grooves 311 from the top of the roller 310. As the roller 310 rotates to the bottom, the fuel in the metering grooves 311 falls down. The amount that falls down each time is constant, so as to achieve the purpose of uniform distribution.

[0043] In a preferred embodiment of the present invention, the mixing mechanism 40 includes a second cylinder 410, a second rotating shaft 420, a mixing plow 430, a third drive assembly 440, and two third bearing seats 450. The second cylinder 410 is connected to the bottom of the hopper 10, and the top of the second cylinder 410 is provided with the feeding channel 411. The two third bearing seats 450 are connected to the bottom ends of the hopper 10. The two ends of the second rotating shaft 420 extend out of the second cylinder 410 and are rotatably connected to the third bearing seats 450. The mixing plow 430 is mounted on the second rotating shaft 420. The drive end of the third drive assembly 440 is connected to one end of the second rotating shaft 420.

[0044] It is worth noting that the mixing effect of fuel and sinter is achieved by rotating the second rotating shaft 420 to drive the mixing plow head 430 to rotate. The mixing plow head 430 can be in the form of bidirectional blades to achieve bidirectional mixing and further enhance the mixing effect. The third bearing seat 450 is used to rotatably mount the second rotating shaft 420, and the second rotating shaft 420 is driven to rotate by the third drive assembly 440.

[0045] Furthermore, the metering grooves 311 of each two adjacent metering groove units are staggered along the circumference of the roller 310.

[0046] It should be noted that this refers to the arrangement of two adjacent metering troughs 311 units by rotating them at a certain angle so that the metering troughs 311 between the two adjacent metering troughs 311 units are not on the same axis, forming a staggered form, so as to form an intermittent material feeding form, avoiding material accumulation, but each feeding still maintains a quantitative amount.

[0047] Furthermore, it also includes an overflow pipe 140, which is disposed outside the silo 10. The top end of the overflow pipe 140 is connected to the upper storage space 120 and disposed above the inclined side wall of the upper storage space 120, and the bottom end of the overflow pipe 140 is connected to the lower storage space 130.

[0048] It should be understood that the overflow pipe 140 is used to quickly guide fuel overflow from the upper storage space 120 into the lower storage space 130, where it falls into the mixing mechanism 40 and is distributed on the surface of the sinter, thereby enhancing the overall safety of the equipment, effectively preventing damage to the equipment caused by abnormal material overflow, and ensuring continuous and stable operation of the equipment under strict safety protection.

[0049] Furthermore, it also includes a radar level gauge 150, which is connected to the side wall of the silo 10 and is located above the top of the overflow pipe 140.

[0050] It should be noted that the radar level gauge 150 is used to determine the real-time fuel thickness in the upper storage space 120 and to give a timely signal, so that the frequency of each drive component can be adjusted according to different situations to ensure that the fuel supply is sufficient but not excessive, and to effectively prevent the fuel from overflowing. Therefore, it is arranged above the top of the overflow pipe 140 to ensure that each position can be detected smoothly. It is understood that the radar level gauge 150 is a relatively mature technical device, so it will not be described in detail here.

[0051] Furthermore, the first drive component 240, the second drive component 320, and the third drive component 440 all adopt variable frequency geared motors.

[0052] It should be noted that using a variable frequency geared motor allows for real-time adjustment of different motor frequencies to control different speeds, thereby changing the material feeding situation according to circumstances.

[0053] To facilitate understanding by those skilled in the art, a preferred embodiment of the operation method is described below. Please refer to the appendix. Figure 3 :

[0054] Step 1: Start the variable frequency reduction motor (first drive assembly 240) of the screw feeder mechanism 20 to drive the first rotating shaft 220 to drive the screw blades 230 to rotate;

[0055] Step 2: Fuel is continuously fed in from the feed port 110 and pushed forward by the spiral blades 230 to cover the entire width of the trolley and fill the upper storage space 120;

[0056] Step 3: When the radar level gauge 150 detects that the fuel level is lower than the level line at point A, the variable frequency reduction motor (first drive component 240) of the screw feeder mechanism 20 outputs at a full frequency of 50Hz, and the first rotating shaft 220 reaches its maximum speed to transport the fuel into the upper storage space 120.

[0057] Step 4: When the radar level gauge 150 detects that the fuel is between the level lines at points A and B, the frequency of the variable frequency reduction motor (first drive component 240) of the screw feeder mechanism 20 is changed to 40Hz output, and the conveying capacity of the screw feeder mechanism 20 is higher than the feeding speed of the spreading mechanism 30.

[0058] Step 5: When the radar level gauge 150 detects that the fuel is between the level lines at points B and C, the frequency of the variable frequency reduction motor (first drive component 240) of the screw feeder mechanism 20 is changed to 30Hz output. The conveying capacity of the screw feeder mechanism 20 is slightly higher than the feeding speed of the spreading mechanism 30.

[0059] Step 6: When the radar level gauge 150 detects that the fuel is between the level lines at C and D, the frequency of the variable frequency reduction motor (first drive component 240) of the screw feeder mechanism 20 is changed to 25Hz output. The conveying capacity of the screw feeder mechanism 20 is equal to the feeding amount of the material spreading mechanism 30. At this time, the conveying speed of the screw feeder mechanism 20 can be gradually reduced to reduce the rate of increase in material layer thickness, so that the radar level gauge 150 is more accurate and can better control the thickness of the material layer to prevent fuel overflow.

[0060] Step 7: In abnormal circumstances, when the radar level gauge 150 detects that the fuel level exceeds the level line at point D, the screw feeder 20 will stop running, but will be restarted after the fuel level drops below the level line at point D.

[0061] Step 8: In abnormal circumstances, when the radar level gauge 150 detects that the fuel exceeds the level line at point D, but the screw feeder 20 does not stop running and continues to deliver fuel, the fuel fills the upper storage space 120, which will damage the equipment. At this time, the overflowing fuel can be diverted to the surface of the sinter in the lower storage space 130 through the overflow pipe 140, and the entire equipment will alarm and stop.

[0062] Step 9: When the radar level gauge 150 detects that the fuel is at the level line at point B, the variable frequency reduction motor (second drive component 320) of the material spreading mechanism 30 starts and feeds the fuel at a uniform speed of 25Hz.

[0063] Step 10: When the steel plant increases the operating speed of the sintering machine according to its own production needs, the frequency of the variable frequency reduction motor (second drive component 320) of the feeding mechanism 30 increases, the speed increases, and the feeding amount increases.

[0064] Step 11: When the steel plant reduces the operating speed of the sintering machine according to its own production needs, the frequency of the variable frequency reduction motor (second drive component 320) of the feeding mechanism 30 increases, the speed increases, and the feeding decreases.

[0065] Step 12: When the radar level gauge 150 detects that the fuel is at the level line at point B, the variable frequency reduction motor (third drive component 440) of the mixing mechanism 40 is started to mix at a uniform speed of 25Hz.

[0066] Step 13: When the frequency of the variable frequency reduction motor (second drive component 320) of the material spreading mechanism 30 increases, the frequency of the variable frequency reduction motor of the mixing device 5-1 increases at the same frequency.

[0067] Step 14: When the frequency of the variable frequency reduction motor (second drive component 320) of the material spreading mechanism 30 decreases, the frequency of the variable frequency reduction motor of the mixing device 5-1 decreases at the same frequency.

[0068] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
