Description

Technical Field

[0001] The utility model relates to the technical field of sintering machines, in particular to a sintering machine material distribution segregation detection device and system. Background Art

[0002] Sintering distribution is the process of evenly distributing the sintering mix across the width of the sintering trolley using a distribution device, while maintaining good air permeability. Distribution requires a certain degree of segregation, with the mix particle size gradually coarsening from top to bottom along the height of the bed, while the fuel distribution gradually decreases from top to bottom.

[0003] The sintering material distribution system consists of a shuttle distributor, a mixing silo, a mud roller feeder, and a nine-roller distributor (or reflector). The mixed material is distributed to the mixing silo by the shuttle distributor, which moves back and forth across the width of the trolley. The mud roller feeder then feeds the mixed material from the silo to the reflector or nine-roller distributor, which then distributes it to the sintering trolley. The shuttle distributor ensures uniformity of the mixed material across the width of the trolley. The mud roller feeder discharges the material from the mixing silo, adjusting the material flow rate by gate opening and speed. The nine-roller distributor or reflector acts as a discharge chute and ensures proper material segregation. The nine-roller distributor uses the gap between the rollers to allow fine particles to flow down to the top of the material bed, while coarse particles flow down the rollers and, due to their rolling motion, to the bottom of the material bed. The reflector adjusts the inclination and height of the reflector to adjust the segregation. Reasonable material distribution segregation can improve the permeability of the material layer, increase production efficiency and sintered ore quality, and reduce solid fuel consumption during sintering.

[0004] The current method for detecting material distribution segregation involves sampling the mixed material distributed to the sintering machine trolley. Specifically, when the designated trolley reaches the bottom of the sintering machine's igniter, the ignition level is adjusted, preventing ignition of the material surface on the trolley. After the trolley has run to the designated limit, the sintering machine is shut down, the fan damper is closed, and the trolley is hoisted out using an overhead crane. Samples are then taken from various locations on the trolley for screening, weighing, and analysis. This existing method for detecting material distribution segregation is labor-intensive, inefficient, and subject to significant detection errors, impacting both sintering machine production efficiency and sintered ore quality. Utility Model Content

DETAILED DESCRIPTION

[0026] To make the purpose, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0027] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, "connected" can mean a direct connection, an indirect connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0028] In this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus comprising the element.

[0029] After research, the applicant found that the main reasons for the defects of traditional technology are as follows: 1. The ignition device needs to be adjusted. In order to detect the distribution of the mixture on the trolley and ensure the state of the mixture, the mixture cannot be ignited. When the scheduled inspection trolley passes under the igniter, the igniter needs to be adjusted to not ignite the material surface of the trolley. This operation requires special personnel to operate and is likely to affect the ignition effect of the material surface of the adjacent trolleys, resulting in poor ignition effect of adjacent trolleys and affecting the quality of the sintered ore. 2. The machine needs to be stopped to lift out the trolley. The lifting of the trolley with unignited mixture requires stopping the machine. During this operation, the cooperation of at least three people, including the sintering machine main control room personnel, the overhead crane operator, and the crane operator, is required. The downtime is more than 10 minutes, which affects the efficiency of the sintering machine and is prone to operational accidents. 3. The detection deviation is large; after the trolley is hoisted out, sampling and testing are carried out, and points are taken in the width and length directions of the trolley, and materials are taken at the corresponding points. Since the mixture is easy to collapse, the particle size composition of the mixture taken out at this point and the original mixture at the corresponding height deviates, which affects the judgment of segregation distribution and makes it impossible to adjust the distributor later.

[0030] In response to the common method of traditional technology for detecting the segregation of sintering machine distribution: the trolley lifting and sampling detection method, the segregation detection device proposed in this application can solve the problems existing in the current detection, such as pre-booking trolleys, adjusting and shutting down ignition devices, sintering machine shutdown, and the cooperation of multiple crane operators and maintenance personnel. It can detect the distribution segregation conditions of different points of the sintering machine online, and then make corresponding adjustments to the equipment operation, improve the distribution effect, improve the efficiency of the sintering machine, and improve the quality of sintered ore.

[0031] First, as Figure 1 As shown, the embodiment of the present invention provides a sintering machine material distribution segregation detection device, comprising: a crossbeam 101, located above the sintering trolley, installed transversely along the width direction of the sintering trolley, and the length of the crossbeam 101 is greater than or equal to the width of the sintering trolley. The transverse installation is horizontal installation.

[0032] A transverse motor 102 is slidably connected to the crossbeam 101. A vertical reclaiming motor 103 is connected to a reclaimer 104 for sampling the mixed material within the sintering trolley. The vertical reclaiming motor 103 is connected to the transverse motor 102, and the reclaimer 104 is retractably connected to the vertical reclaiming motor 103. The reclaimer 104 is vertically positioned above the sintering trolley. The transverse motor 102 is used to drive the vertical reclaiming motor 103 and the reclaimer 104 to move on the crossbeam. The vertical reclaiming motor 103 is used to control the reclaimer 104 to move vertically up and down to sample the mixed material within the sintering trolley.

[0033] Specifically, the lateral movement motor 102 is slidably connected to the crossbeam 101, which is connected to the vertical material reclaiming motor 103 connected to the material reclaimer 104. When the lateral movement motor 102 is in operation, it can slide on the crossbeam 101, thereby driving the vertical material reclaiming motor 103 and the material reclaimer 104 to move in the width direction of the sintering trolley. In one embodiment, the crossbeam 101 can be an I-beam.

[0034] In one embodiment, the lateral movement motor 102 can be slidably connected to the crossbeam 101 via a slider. The lateral movement motor 102 can be an AC asynchronous motor, a servo motor, a stepper motor, or other motors that can support forward and reverse rotation.

[0035] In another embodiment, Figure 2 As shown, the material picker 104 may include a tubular device 1042 and a connecting member 1041 , the tubular device 1042 is connected to the connecting member 1041 , the tubular device 1042 is arranged downward, and the vertical material picker motor 103 is telescopically connected to the connecting member 1041 .

[0036] Alternatively, the connecting member 1041 may be a bolt. When the vertical reclaiming motor 103 is in operation, the bolt is controlled to rotate up and down. When the bolt rotates downward, the tubular member 1042 is moved downward; when the bolt rotates upward, the tubular member 1042 is moved upward. This allows the vertical reclaiming motor 103 to control the up and down movement of the tubular member 1042.

[0037] The length of the bolt is greater than or equal to the length of the tubular device 1042. In the initial state, the bottom of the bolt is connected to the vertical material reclaiming motor 103. The vertical material reclaiming motor 103 can be a linear motor or a lifting motor.

[0038] Optionally, the length of the tubular device 1042 can be between 1000 mm and 1100 mm. Furthermore, when the detection device is not in use, in order to prevent the material picker 104 from scratching the sintering trolley, the vertical height between the bottom of the beam 101 and the upper edge of the sintering trolley's railing is greater than or equal to 1200 mm.

[0039] In a specific embodiment, the start and stop of the lateral movement motor 102 and the vertical material taking motor 103 can be manually controlled.

[0040] Preferably, the segregation detection device may further include a controller, which is electrically connected to the lateral movement motor 102 and the vertical material-retrieving motor 103 , respectively, and is used to control the operation of the lateral movement motor 102 and the vertical material-retrieving motor 103 .

[0041] Specifically, the controller may include a left key, a right key, and a stop key for the lateral movement motor 102, and an up key, a down key, and a stop key for the vertical reclaiming motor 103. The left key and the right key of the lateral movement motor 102 are used to control the lateral left and right movement of the reclaimer 104, and the up key and the down key of the vertical reclaiming motor 103 are used to control the reclaiming and returning of the reclaimer 104. The controller may be a single-chip microcomputer controller or a PLC controller.

[0042] Furthermore, in order to facilitate the operation and adjustment of the material picker 104, the segregation detection device can also include an operation screen, which is communicatively connected to the controller. The operation screen is used to display the working status of the horizontal moving motor 102, the vertical material picking motor 103 and the material picker 104 in real time, which is conducive to achieving precise control of the material picker 104.

[0043] Furthermore, if Figure 2 As shown, the axial direction of the tubular device 1042 may include multiple spaced-apart material taking slots 1043. In actual use, the tubular device 1042 is controlled to be inserted into the mixed material in the sintering trolley, and the multiple material taking slots 1043 of the tubular device 1042 are filled with mixed material samples at different vertical directions at that position.

[0044] Specifically, the number of material troughs 1043 can be 3-5, and the shape of the material troughs 1043 can be rectangular. Of course, as other optional embodiments, the number of material troughs 1043 can be more, and the shape of the material troughs 1043 can also be elliptical or other shapes, which is not limited in this application.

[0045] In this embodiment, the diameter of the tubular device 1042 may range from 45 to 55 mm, for example, the diameter is 50 mm.

[0046] Furthermore, the tubular device 1042 may include a scale. Specifically, a scale is marked on the outside of the device, with the bottom scale of the tubular device 1042 being zero. Each time a sample is taken, the tubular device 1042 is moved down to the lowest point to sample the mixture at the corresponding thickness.

[0047] Furthermore, in order to facilitate the acquisition of the sampled mixed material, the material reclaimer 104 is detachably connected to the vertical material reclaimer motor 103. The material reclaimer 104 can be installed before sampling and removed after sampling.

[0048] In this embodiment, the material taking position of the segregation detection device is first determined, the segregation detection device is turned on, the lateral movement key is activated, and the material taker 104 is moved to this position; the vertical material taking down key is activated, and the material taker 104 is moved downward to the bottom of the sintering material layer, and the stop key is pressed; the vertical material taking up key is activated, and the material taker 104 is moved upward until it completely leaves the sintering material layer; the material taker 104 of the segregation distribution detection device is removed, placed in a horizontal position, and the mixed materials from different parts are taken out in sequence from the top of the material taker 104.

[0049] Furthermore, the segregation detection device may further include: a sifter for sieving the sampled mixed material and an electronic scale for weighing the sieved mixed material.

[0050] As an embodiment, the sifter may include two sieves, wherein the mesh size of one sieve is 3 mm and the mesh size of the other sieve is 5 mm. Optionally, the electronic scale may be a 3 kg electronic scale.

[0051] The taken-out mixture is sieved with sieves with apertures of 3 mm and 5 mm, and weighed with an electronic scale to calculate the particle size composition of the mixture at different positions along the height of the material layer.

[0052] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods:

[0053] (1) Determine the material taking position of the segregation detection device, turn on the segregation detection device, start the equipment lateral movement key, and move the material taker 104 to the position;

[0054] (2) Start the vertical material reclaiming down key, move the reclaimer 104 downward to the bottom of the sintering material layer, and press the stop key;

[0055] (3) Activate the vertical material removal button up key to move the material removal device 104 upward until it is completely away from the sintering material layer;

[0056] (4) Remove the material dispensing device 104 from the segregation distribution detection device, place it in a horizontal position, and take out the mixed materials at different thicknesses from the top of the material dispensing device 104 in sequence;

[0057] (5) The removed mixed material is sieved with sieves with apertures of 3 mm and 5 mm, weighed with an electronic scale, and the particle size composition of the mixed material at different positions along the material layer is calculated. This allows the distribution effect of the sintering distribution system to be tested.

[0058] This device can be used to sample and analyze the mixture at any position on the sintering machine trolley and within any material layer thickness range. Sampling and analyzing the mixture using this material removal device can be performed under normal operating conditions of the sintering machine, without adjusting the ignition device or shutting down the sintering machine. This device can quickly detect material layer segregation and is simple to operate with low workload, requiring only one person to complete the task. Compared with traditional detection methods, this device is more accurate, has smaller errors, and can truly reflect the distribution of the mixture on the trolley, facilitating precise adjustment of the distribution device at a later stage. The mixture removed at this point will not deviate from the particle size composition of the mixture at the original corresponding height due to the collapse of the mixture, resulting in a smaller detection deviation for the segregation detection device.

[0059] In summary, the present embodiment provides a sintering machine material distribution segregation detection device, which adopts a method in which a motor controls the material taker to move horizontally within the width of the trolley and the material taker motor moves vertically to sample the mixed material distributed on the trolley for detection.

[0060] Second, as Figure 3 As shown, an embodiment of the present invention provides a sintering machine distribution system, comprising: a nine-roller distributor 200, a flat material net 300 and the segregation detection device 100 of the first aspect described above, wherein the segregation detection device 100 is arranged between the nine-roller distributor 200 and the flat material net 300.

[0061] Specifically, the crossbeam and the material taker of the segregation detection device 100 are both located above the sintering trolley 400, so that the material taker can be inserted into the mixed material in the sintering trolley to take out the material. Figure 3 As shown, the sintering material distribution system may further include a mixing silo 500 and a mud roller feeder 600 .

[0062] The present embodiment provides a sintering machine distribution system, whose implementation principle and technical effects are the same as those of the aforementioned device embodiment. For the sake of brief description, for matters not mentioned in the device embodiment, reference may be made to the corresponding contents in the aforementioned device embodiment.
