Description

Technical Field

[0001] This utility model relates to the field of sintering technology, specifically to a sintering fuel secondary addition and distribution device. Background Technology

[0002] In the solid fuel fractionation process for sintering, a portion of the fuel is mixed with the sintering mixture and participates in the granulation of the sintering mixture. Another portion of the externally added fuel is applied to the surface of the mixture particles via the upper layer of the sintering machine trolley after secondary mixing of the sintering mixture. This effectively reduces the fuel consumption of sintering solids, saves energy and reduces carbon emissions, while also improving the sintering yield, utilization coefficient, and strength of the sintered ore. The main component of sintering solid fuel is coke powder. Currently, there are no mature examples of methods for uniformly adding externally added coke powder to the surface of the sintering mixture particles. How to achieve uniform addition of coke powder fuel in the width direction of the sintering trolley using a feeding device is a current challenge in the industry.

[0003] Existing secondary feeding methods typically achieve uniform fuel width feeding by setting up large hoppers to ensure a continuous supply of fuel. However, this feeding system is complex to set up, occupies a large space, is costly, and lacks adaptability, causing numerous inconveniences in practical applications. Moreover, storing too much coke powder due to the small amount of fuel added poses certain safety hazards. Furthermore, the feeding rate of existing screw conveyors is not well matched with the discharge rate of the discharge device, easily leading to problems such as insufficient feeding (no discharge at the end of the conveyor) or excessive feeding (fuel not being discharged in time, causing fuel compression). Utility Model Content

[0004] The main purpose of this utility model is to provide a secondary addition and distribution device for sintering fuel, so as to solve the problem that it is not easy to achieve uniform distribution of sintering fuel in the width direction of the sintering trolley during secondary distribution.

[0006] A secondary fuel addition and feeding device for sintering includes a secondary feeding device and a sintering machine frame. The secondary feeding device includes a housing, a fuel delivery device, a hinge support, a weighing sensor, and a feeding roller. The bottom of the housing is connected to the sintering machine frame via the hinge support and the weighing sensor. The housing is located directly above the sintering trolley and is horizontally positioned along the width of the sintering trolley. The hinge support and the weighing sensor are symmetrically arranged on both sides of the housing. The weighing sensor is symmetrically arranged at least at both ends of one side of the housing.

[0007] The housing has a receiving cavity, the top of which is connected to a feed inlet, and the bottom of which is connected to a discharge outlet. A fuel delivery device is rotatably mounted within the receiving cavity to deliver fuel from the feed inlet to the end of the cavity. The length of the discharge outlet matches the width of the sintering trolley. A feeding roller is rotatably positioned directly below the discharge outlet. When the feeding roller rotates, fuel is discharged from the discharge outlet. When the feeding roller stops rotating, fuel discharge stops from the discharge outlet.

[0008] Preferably, the sintering machine frame includes a first crossbeam and a second crossbeam that are parallel to each other, both of which are mounted above the sintering trolley along the width direction of the sintering trolley. There are two hinge supports and two load cells.

Detailed Implementation

[0026] The technical solution of this utility model is illustrated below. The scope of protection of this utility model includes, but is not limited to, the following embodiments.

[0027] Please refer to Figures 1 to 4 A secondary fuel addition and feeding device for sintering includes a secondary feeding device 1 and a sintering machine frame 2. The secondary feeding device 1 includes a housing 105, a fuel conveying device 104, a hinge support 103, a weighing sensor 107, and a feeding roller 106. The bottom of the housing 105 is connected to the sintering machine frame 2 via the hinge support 103 and the weighing sensor 107. The housing 105 is located directly above the sintering trolley 3 and is horizontally arranged along the width direction of the sintering trolley 3. The hinge support 103 and the weighing sensor 107 are symmetrically arranged on both sides of the housing 105. The weighing sensor 107 is symmetrically arranged at at least two ends on one side of the housing 105.

[0028] A receiving cavity is provided inside the housing 105. The top of the receiving cavity is connected to the feed inlet 102, and the bottom of the receiving cavity is connected to the discharge outlet. A fuel conveying device 104 is rotatably disposed inside the receiving cavity to convey fuel (mainly coke powder) from the feed inlet 102 to the end of the receiving cavity. The length of the discharge outlet matches the width of the sintering trolley 3. A feeding roller 106 is rotatably disposed directly below the discharge outlet. When the feeding roller 106 rotates, material is discharged from the discharge outlet. When the feeding roller 106 stops rotating, material discharge from the discharge outlet stops.

[0029] In the technical solution of this utility model, the housing 105 is mounted on the top of the sintering trolley via the sintering machine frame 2, and the housing 105 is horizontally arranged along the width direction of the sintering trolley 3. The length of the discharge port of the housing 105 matches the width of the sintering trolley 3. The fuel conveying device 104 can convey the fuel from the feed port 102 to the end of the receiving cavity and fall from the discharge port to the sintering trolley 3. The material distribution roller 106 directly below the discharge port can control the discharge. One side of the housing 105 is supported by a hinge support 103, and the opposite side is supported by a weighing sensor 107 symmetrically arranged with the hinge support 103. The weighing sensor 107 is symmetrically arranged at least at both ends of the housing 105. The hinge support 103 can absorb some vibration and improve the stability of the device. Due to the symmetrical design, the distribution of fuel in the housing 105 can be known through the weighing sensor 107, which is beneficial to match the feed and discharge of the receiving cavity and ensure that there is always material at the end of the receiving cavity, thereby achieving uniform material distribution in the width direction of the sintering trolley 3.

[0030] Specifically, the sintering trolley 3 passes under the sintering machine frame 2, and the secondary material feeding device 1 is located directly above the sintering trolley 2, after the roller material feeding device 4 (for primary material feeding) and before the ignition sintering device.

[0031] Preferably, the sintering machine frame 2 includes a first crossbeam 201 and a second crossbeam 202 that are parallel to each other. Both the first crossbeam 201 and the second crossbeam 202 are mounted above the sintering trolley 3 along the width direction of the sintering trolley 3. There are two hinge supports 103 and two load cells 107. Two first connecting seats 110 are symmetrically arranged at both ends of one side of the housing 105, and two second connecting seats 111 are symmetrically arranged at both ends of the opposite side of the housing 105. Each first connecting seat 110 corresponds to a hinge support 103, and the first connecting seat 110 is connected to the first crossbeam 201 through the corresponding hinge support 103. Each second connecting seat 111 corresponds to a load cell 107, and the second connecting seat 111 is connected to the second crossbeam 202 through the corresponding load cell 107.

[0032] The distribution of fuel within the containment cavity can be determined by the weighing of the load cell 107, thus helping the system to handle different fuel distributions accordingly. In one embodiment, two load cells 107 are respectively located at the front and rear ends of the housing 105. Before feeding, the two load cells weigh 300 kg each. After feeding, the load cell at the front end of the housing 105 weighs 360 kg, and the load cell at the rear end weighs 350 kg, indicating that there is 220 kg (110 kg × 2) of fuel in the housing 105. The normal reading range of the load cell 107 is set to 330~380 kg. Within this range, the system operates normally. If the weight is less than this, the conveyor is first turned on to bring the corresponding amount of fuel into the housing 105 (i.e., the reading of the load cell 107 reaches the normal range of fuel amount) before the feeding roller 106 is turned on to feed the fuel. If the weight exceeds this value, the feeding will be stopped first, and the cloth roller 106 will be turned on to release a portion of the fuel so that the amount of fuel in the housing 105 reaches the preset range (i.e., the normal reading range set by the weighing sensor 107) before feeding can begin. This will ultimately achieve a balance between feeding and discharging, and prevent uneven distribution of the material in the width direction due to insufficient fuel or material blockage due to excessive fuel.

[0033] Preferably, the width of the receiving cavity gradually decreases from the feed inlet 102 side to the discharge outlet side. This facilitates the flow of fuel from the discharge outlet. In one embodiment, the housing 105 is U-shaped, and the discharge outlet is V-shaped (with gradually approaching baffles on both sides of the discharge outlet to guide the fuel downward).

[0034] Preferably, the fuel delivery device 104 includes a first rotating shaft 1041, a first helical blade 1042, and a second helical blade 1043. One end of the rotating shaft 1041 is rotatably connected to the end wall of the housing 105, and the other end is rotatably connected to the opposite end wall of the housing 105. The first helical blade 1042 and the second helical blade 1043 are both fixedly connected to the outer wall of the first rotating shaft 1041, and the second helical blade 1043 is disposed outside the first helical blade 1042. The first helical blade 1042 and the second helical blade 1043 rotate in opposite directions.

[0035] By using the first helical blade 1042 and the second helical blade 1043 with opposite rotation directions, not only can efficient fuel transportation be achieved, but the shearing and backflow effects generated by the reverse helices can also improve the uniformity of the fabric distribution and anti-clogging performance, which is beneficial to the continuous and stable supply of fuel. Specifically, both the first helical blade 1042 and the second helical blade 1043 are welded to the surface of the first rotating shaft 1041, and the contact point between the second helical blade 1043 and the first helical blade 1042 is fixed by welding to improve the stability of the structure. In one embodiment, both the first helical blade 1042 and the second helical blade 1043 are made of wear-resistant steel (such as NM400 wear-resistant steel or Q355 wear-resistant steel).

[0036] Preferably, the device further includes a first driving device 101. The first driving device 101 is fixedly mounted on the sintering machine frame 2 for driving the first rotating shaft 1041 to rotate.

[0037] Specifically, the first drive device 101 includes a first drive motor and a first torque arm. The output shaft of the first drive motor is coaxially connected to the first rotating shaft 1041 via a coupling, and the first drive motor is fixedly connected to the sintering machine frame 2 via the first torque arm to improve the stability of the first drive motor. The first drive motor is a variable frequency motor, and the speed of the output shaft is controlled by frequency conversion, thereby controlling the speed of the second rotating shaft 1041.

[0038] Preferably, the fabric roller 106 is spaced a predetermined distance from the discharge port. The fabric roller 106 includes a second rotating shaft 1061 and a plurality of fabric plates 1062 evenly spaced along the circumference of the second rotating shaft 1061. The fabric plates 1062 extend along the length of the second rotating shaft 1061. Mounting plates are respectively provided at both ends of the bottom of the housing 105. The discharge port is located between two mounting plates. One end of the second rotating shaft 1061 is rotatably connected to one of the mounting plates, and the other end is rotatably connected to the other mounting plate.

[0039] Specifically, the preset distance between the feeding roller 106 and the discharge port is 1-2 mm. After the fuel flows out of the discharge port, it falls between the two feeding plates 1062. When the second rotating shaft 1061 is not rotating, the fuel stays between the two feeding plates 1062; when the second rotating shaft 1061 rotates, the fuel falls from between the two feeding plates 1062 onto the sintering trolley 3. The feeding plates 1062 are made of wear-resistant steel (such as NM400 wear-resistant steel or Q355 wear-resistant steel).

[0040] Preferably, the fabric plate 1062 is detachably connected to the second rotating shaft 1061.

[0041] Specifically, the fabric plate 1062 is connected to the second rotating shaft 1061 by screws. In one embodiment, the fabric plate 1062 includes a first plate and a second plate, the first plate and the second plate having the same length, and the length is not less than the length of the discharge port. The first plate is arc-shaped, and the arc of the first plate is consistent with the arc of the outer wall of the second rotating shaft 1061. The first plate is in close contact with the second rotating shaft 1061, and the second plate is fixedly connected to the side of the first plate opposite to the second rotating shaft 1061. The first plate has a plurality of screw holes penetrating the plate thickness, the screw holes being evenly distributed along the length direction of the first plate, and the screw holes being symmetrically distributed on both sides of the second plate. Screws are threaded through the screw holes and threadedly connected to the second rotating shaft 1061 to connect the fabric plate 1062 to the second rotating shaft 1061.

[0042] Preferably, the device further includes a second drive unit. The second drive unit is fixedly mounted on the sintering machine frame 2 to drive the second rotating shaft 1061 to rotate.

[0043] Specifically, the second drive device 109 includes a second drive motor and a second torque arm. The output shaft of the second drive motor is coaxially connected to the second rotating shaft 1061 via a coupling, and the second drive motor is fixedly connected to the sintering machine frame 2 via the second torque arm to improve the stability of the first drive motor. The second drive motor is a variable frequency motor, and the speed of the output shaft is controlled by frequency conversion, thereby controlling the speed of the second rotating shaft 1061.

[0044] Preferably, the top of the housing 105 has overflow ports at both ends that connect to the receiving cavity. The overflow ports are provided with grilles 108.

[0045] When the load cell 107 fails and a large amount of fuel accumulates in the housing 105, the fuel will overflow onto the sintering trolley 3 through the overflow port, without affecting the equipment. Specifically, the grille 108 is detachably installed at the overflow port, and the holes of the grille 108 are small to prevent debris (such as bolts) from falling into the housing 105 from the overflow port.

[0046] Preferably, the feed inlet 102 is located at one end of the top of the housing 105. This arrangement allows fuel to easily enter one end of the receiving cavity from the feed inlet 102 and then be transported to the other end of the receiving cavity via the fuel conveying device 104, thereby ensuring a uniform distribution of fuel within the receiving cavity and facilitating the uniform falling of fuel from the discharge port onto the sintering trolley 3.

A fuel conveying device 104 is rotatably disposed inside the receiving cavity to convey fuel (mainly coke powder) from the feed inlet 102 to the end of the receiving cavity. The length of the discharge outlet matches the width of the sintering trolley 3. A feeding roller 106 is rotatably disposed directly below the discharge outlet.
