Description

[0001] The present invention relates to the technical field of sintering machines, and in particular to an electromagnetic material loosening system and method for a sintering machine trolley. Background Art

[0002] The belt sintering machine is an industrial equipment primarily used for the sintering of iron ore. Due to its importance in modern steel production, the optimization of the belt sintering machine has always been a research focus in the steel industry. Thick-bed sintering, due to its thicker bed, can process more material in a single sintering process, thereby improving production efficiency. Heat is also more easily retained in the thicker bed, enabling more efficient use of thermal energy. Thicker beds provide more uniform temperature distribution during the sintering process, helping to improve the overall quality of the sintered ore. Therefore, it has become a research hotspot and optimization direction.

[0003] In existing thick-bed sintering machines, the thick material bed is often over-compacted due to the combined effects of wind pressure and gravity. This over-compaction increases the resistance within the material bed, affecting the efficiency and quality of the sintering process. The increased resistance can lead to uneven heating and sintering within the material bed, which can reduce the quality of the sintered product. In addition, this also means higher energy consumption and operating costs, as more energy is required to achieve the desired sintering effect through the over-compacted layer.

[0039] Please see the attached Figure 1-3 In one embodiment of the present invention, an electromagnetic loosening system for a sintering machine trolley 50 includes a moving system 10, an electromagnetic loosening mechanism 20, a monitoring system 30, and a control system 40. The specific solution is as follows:

[0040] The moving system 10 is used to adjust the position of the electromagnetic loosening mechanism 20, is arranged at intervals below the sintering machine trolley 50, and is movably arranged along the extension direction of the sintering machine trolley 50; the electromagnetic loosening mechanism 20 is used to generate lifting force on the material layer of the sintering machine trolley 50 to loosen the material layer, is connected to the top of the moving system 10, and the electromagnetic loosening mechanism 20 is adjustably arranged along the vertical position; the monitoring system 30 is used to collect real-time data of the material layer of the sintering machine trolley 50, is connected to the sintering machine trolley 50, and is communicated with the control system 40; the control system 40 is used to receive real-time data fed back by the monitoring system 30 and output current to the electromagnetic loosening mechanism 20, and the control system 40 is electrically connected to the electromagnetic loosening mechanism 20.

[0041] Specifically, the mobile system 10 can adjust the position of the electromagnetic loosening mechanism 20. The relative position between the magnetic field generated by the electromagnetic loosening mechanism 20 and the target sintering machine trolley 50 material layer is different depending on the position of the electromagnetic loosening mechanism 20. It can adapt to changing the magnetic field strength to adjust the generated force, and can also be set in the material layer area with high compaction to enhance the loosening effect, thereby meeting the needs of different loosening conditions in actual work and improving the adaptability of the device. It is arranged at intervals below the sintering machine trolley 50 so that the electromagnetic loosening mechanism 20 can be arranged at intervals below the sintering machine trolley 50 after installation; the electromagnetic loosening mechanism 20 is used to affect the compaction of the material layer, and it adopts a combination of a magnetic conductor 210 and a coil group 220, and the magnetic conductor 210 is connected to the connecting plate 130. The coil groups 220 are all sleeved on the magnetic conductor 210 to form a structure similar to an electromagnetic coil, which serves as a component constituting the core of the loosener and is used to generate a changing magnetic field to loosen the material layer. The coil group 220 uses multiple coil layers to generate a superimposed magnetic field, thereby enhancing the magnetic field strength. The specific number can be selected according to actual needs. Preferably, a copper coil can be used. The copper coil has good conductivity, so that the current passes through the coil efficiently to generate a stronger magnetic field, and the magnetic permeability block can use silicon steel sheets to utilize its high magnetic permeability to enhance the magnetic field strength. It is worth mentioning that the entire electromagnetic loosening mechanism 20 needs to be set directly above the sintering machine trolley 50 to ensure that the force generated is upward, thereby forming a lift to loosen the material layer and reduce the material layer resistance.

[0042] Among them, the principle of the electromagnetic loosening mechanism 20 is mainly based on the action of the Lorentz force, which is the force generated when current passes through a conductor in a magnetic field. In application, the sintered iron ore layer itself acts as a conductor, and the changing magnetic field generated by the electromagnetic coil (magnetic conductor 210 and coil group 220) is used to excite the current in the material layer, and then affect its compaction through the Lorentz force, specifically F = I × (L × B); I is the current intensity in the conductor, L is the length of the conductor, which in this case can be understood as the length of the material layer movement path, and B is the magnetic field strength; in the application of electromagnetic loosening, by controlling the current in the electromagnetic coil (that is, changing the current intensity I) and the magnetic field strength (B), the magnitude of the Lorentz force acting on the material layer can be accurately adjusted, thereby generating an upward force (lift) effect on the material layer to affect the compaction of the material layer, so it is necessary to use the control system 40 to adjust the current intensity and current frequency.

[0043] In detail, the control system 40 is used to provide current to the electromagnetic loosening mechanism 20. The control system 40 changes the strength and direction of the magnetic field by adjusting the current intensity and the frequency of the alternating current in the electromagnetic loosening mechanism 20. The strength of the electromagnetic field directly affects the magnitude of the Lorentz force, so the control system 40 is electrically connected to the electromagnetic coil; and in order to understand the changes in the compaction state of the material layer in real time, it is also necessary to set up the monitoring system 30 to monitor the compaction state of the material layer in real time. In this way, the control system 40 also has the function of synchronously collecting the system for analysis. These data (compactness of the material layer) are fed back to the control system 40 in real time. The control system 40 adjusts the current and frequency of the electromagnetic coil according to these feedbacks to achieve precise control of the compaction of the material layer. Therefore, the monitoring system 30 needs to be communicated with the control system 40 to feedback and receive data, and the monitoring system 30 needs to be connected to the sintering machine trolley 50 to be set on the sintering belt of the sintering machine trolley 50 to ensure accurate data collection, and it is best installed in a position close to the electromagnetic stirrer to ensure that changes in the compaction of the material layer can be accurately monitored.

[0044] As a preferred embodiment of the present invention, the moving system 10 includes a moving track 110, a power trolley 120 and a connecting plate 130, the inner side of the moving track 110 has a slide groove 111, and the power trolley 120 has a power wheel 121 and a support wheel 122; wherein, the moving track 110 is arranged in parallel below the sintering machine trolley 50, the power wheel 121 of the power trolley 120 is arranged on the moving track 110, and the support wheel 122 of the power trolley 120 is slidably connected to the slide groove 111, the connecting plate 130 is connected to the top of the power trolley 120 and is adjustable vertically, and the electromagnetic loosening mechanism 20 is connected to the connecting plate 130 and is arranged at intervals below the sintering machine trolley 50.

[0045] It should be noted that the movable track 110 is arranged parallel to the bottom of the sintering machine trolley 50 so as to be consistent with the moving direction of the material layer, so that although the electromagnetic loosening mechanism 20 changes its position after movement, it is still directly below the sintering machine trolley 50, which can ensure the best loosening effect; the connecting plate 130 is used for the installation of the electromagnetic loosening mechanism 20, which is connected to the top of the power trolley 120 to drive the electromagnetic loosening mechanism 20 to be movable and adjustable along the extension direction of the sintering machine trolley 50. Furthermore, the connecting plate 130 is arranged to be adjustable vertically, so that the vertical position of the electromagnetic stirring mechanism can also be adjusted to adjust the spacing between the electromagnetic loosening mechanism 20 and the material layer and adjust the magnetic field distribution; the power wheel 121 of the power trolley 120 is placed on the movable track 110 for rolling movement, and the support wheel 122 is used to slide in the slide groove 111 of the movable track 110, which can play a guiding role to prevent the power trolley 120 from derailing and offset.

[0046] As a preferred embodiment of the present invention, the mobile system 10 also includes a vertical adjustment component 140, which includes two screw rods 141 arranged relatively along the length direction of the connecting plate 130 and four sliding rods 142 distributed in a matrix shape. The bottom ends of the sliding rods 142 and the screw rods 141 are both connected to the power trolley 120, and the top ends of the sliding rods 142 and the screw rods 141 pass through and extend out of the connecting plate 130, and the screw rods 141 are threadedly connected to the connecting plate 130.

[0047] It is worth noting that the vertical adjustment component 140 is used to adjust the vertical position of the connecting plate 130, thereby driving the adjustment of the vertical position of the electromagnetic loosening mechanism 20. It includes a screw rod 141 and a slide rod 142. The screw rod 141 adopts the form of two relatively arranged along the length direction of the connecting plate 130. Its bottom end is connected to the power trolley 120 and is rotatably arranged. It is threadedly connected to the connecting plate 130 to achieve the up and down adjustment of the connecting plate 130 when rotating; and the slide rod 142 plays a certain guiding role, so that the four corners of the connecting plate 130 can be synchronously and evenly raised and lowered when moving. Therefore, the slide rod 142 adopts the form of four matrix-shaped distributions to respectively pass through the connecting plate 130.

[0048] Furthermore, the horizontal cross-sections of the magnetic conductor 210 and the coil assembly 220 are square.

[0049] It should be noted that the square structure can easily correspond to the shape of the sintering machine trolley 50, so that the magnetic field distribution range can correspond to the width of the sintering machine trolley 50 to ensure the loosening effect; further, the transverse length of the magnetic conductor 210 is matched with the transverse width of the sintering machine trolley 50, which means that the transverse length of the magnetic conductor 210 is the same as the transverse width of the sintering machine trolley 50, so that the magnetic field distribution can cover the sintering machine trolley 50, ensuring the coverage range of the lift and the good and uniform loosening effect. It can be understood that the transverse here refers to the width direction of the sintering machine trolley 50.

[0050] Furthermore, the monitoring system 30 includes a pressure sensor, which is installed on the sintering belt of the sintering machine trolley 50 and is in communication with the control system 40 .

[0051] It should be understood that the pressure sensor is used to monitor the real-time pressure value of the material layer, thereby reflecting the compaction degree of the material layer under the combined action of wind pressure and gravity. By feeding back the data to the control system 40 in real time, the control system 40 adjusts the current and frequency of the electromagnetic coil according to these feedbacks, thereby achieving precise control of the looseness of the material layer.

[0052] The present application also provides an electromagnetic loosening method for a sintering machine trolley 50, which is applied to the electromagnetic loosening system for the sintering machine trolley 50 as described above, and includes the following steps:

[0053] S1, sets the initial current parameters of the control system 40 according to the initial compaction state of the material layer, and determines the initial position of the electromagnetic loosening mechanism 20; wherein, the initial current parameters include initial current intensity and initial current frequency; it should be noted that an initial value is set in this way, so that the current intensity can be gradually increased, the current frequency can be changed, etc. based on this initial value, thereby changing the magnetic field and adjusting the stirring force; and the initial position is a preset loosening position, which can be moved to an area with a high degree of compaction for targeted loosening according to real-time monitoring.

[0054] S2, provides current to the electromagnetic loosening mechanism 20 through the control system 40, so that the electromagnetic loosening mechanism 20 generates a lifting force for loosening the material layer; it should be noted that after power is turned on, the current passes through the electromagnetic coil (magnetic conductor 210 and coil group 220) to generate a magnetic field, and the material layer acts as a conductor to pass through the magnetic field, thereby generating a Lorentz force as a force for loosening the material layer, achieving a stirring effect, and affecting the compaction of the material layer.

[0055] S3, the real-time compaction of the material layer of the sintering machine trolley 50 after electromagnetic loosening is obtained through the monitoring system 30, and the feedback is given to the control system 40; it can be understood that after the Lorentz force is generated to loosen the material, the real-time flow conditions of the material layer in the sintering machine trolley 50 will change, such as the compaction of the material layer, etc. After the real-time data is obtained through the monitoring system 30 (pressure sensor), it is fed back to the control system 40 to facilitate subsequent targeted adjustments.

[0056] S4, analyzes the real-time compaction degree of the material layer of the sintering machine trolley 50, forms a correction current parameter through the output of the control system 40, and adjusts the correction position of the electromagnetic loosening mechanism 20 through the mobile system 10 to form a correction lift for loosening the material layer of the sintering machine trolley 50; wherein, the correction current parameter includes a correction current intensity and a correction current frequency; it should be noted that after receiving the real-time data fed back by the monitoring system 30, the control system 40 continuously adjusts the current intensity I and the magnetic field intensity B according to the formula F=I×(L×B), so as to maintain or change the force on the material layer; specifically, according to the feedback data, increases or decreases the current intensity I and the magnetic field intensity B. The magnetic field strength is adjusted by reducing the current intensity, thereby changing the magnitude of the Lorentz force, which directly affects the effect of the lift on the material layer. For example, by increasing the current intensity or the magnetic field intensity, the Lorentz force will be increased, forming a correction force (corrected lift) for loosening the material layer of the sintering machine trolley 50, so as to loosen the material layer and avoid excessive compaction. At the same time, the position of the electromagnetic loosening mechanism 20 can also be adjusted by the mobile system 10 to affect the real-time data of the material layer, and according to the feedback adjustment, it can be moved to the area with greater compaction to carry out targeted loosening. Thus, the stirring effect can be adjusted comprehensively through the current intensity, current frequency and the position of the electromagnetic stirring mechanism.

[0057] S5, repeat steps S2 to S4.

[0058] It can be understood that the continuous monitoring and adjustment cycle ensures that the loose material layer is carried out according to the expected goals and remains loose even when production conditions change, so as to optimize the sintering process, improve efficiency and product quality, thereby solving the problem of excessive compaction due to the combined effect of wind pressure and gravity, reducing the resistance of the material layer, and significantly reducing the energy consumption of wind resistance. The key to this method is the ability to dynamically adjust the Lorentz force based on real-time monitoring data to adapt to the immediate needs of the production process.
