Description

Technical Field

[0001] This invention relates to the field of dust suppression equipment technology, and in particular to a dust suppression device and process for processing magnesia-carbon bricks for electric furnaces. Background Technology

[0002] The processing of magnesia-carbon bricks for electric furnaces generates a large amount of dust. If this dust is not dealt with in a timely manner, it will not only pollute the working environment but also endanger the health of operators and may affect the normal operation of production equipment.

[0003] Traditional dust suppression devices mostly use a single filtration method, where dust-laden gas directly enters the filter element for filtration. This causes a large amount of dust to accumulate rapidly on the surface of the filter element, making it prone to clogging. Frequent cleaning or replacement is required, which not only increases maintenance costs but also reduces dust suppression efficiency. Summary of the Invention

[0004] Based on the technical problems existing in the prior art, the present invention proposes a dust reduction device and process for processing magnesia-carbon bricks for electric furnaces.

[0005] This invention proposes a dust collection device for processing magnesia-carbon bricks in an electric furnace, comprising a dust collection box. A partition is fixedly connected inside the dust collection box, and an air outlet is provided on the partition. A filter bag covering the air outlet is fixedly connected to the bottom of the partition. An air inlet pipe and an air outlet pipe are provided on the outer wall of the dust collection box, located below and above the partition, respectively. A fan is fixedly connected to the other end of the air outlet pipe. The direction of the air inlet pipe is tangential to the dust collection box. A slag discharge port is provided at the bottom of the dust collection box, and a feeder is connected to the slag discharge port. The air enters the dust collector tangentially through the inlet duct, forming a rotating airflow inside. Some of the heavier dust particles are thrown against the inner wall of the dust collector by centrifugal force and fall to the slag discharge port. The remaining dust-laden gas rises and is filtered through the filter bags, where the dust is trapped on the surface. The filtered clean gas is discharged through the outlet and outlet duct under the action of the fan. The collected dust is discharged from the slag discharge port through the feeder. This effectively reduces the amount of dust accumulation on the surface of the filter bags, thereby delaying the clogging time of the filter bags.

[0006] Preferably, the filter bag is equipped with a dust removal mechanism, which includes a cleaning frame with a polygonal cross-section. A speed-regulating motor is fixedly connected to the inner wall of the top of the dust collector. The cleaning frame is connected to the output shaft of the speed-regulating motor. The filter bag is fitted onto the cleaning frame, and the bottom of the filter bag is connected to a pull rope through multiple connectors. The other end of the pull rope is fixed to the inner wall of the dust collector through connectors. During the dust removal process, the filter bag will adhere to the cleaning frame due to negative pressure and form a polygonal shape. When cleaning the filter bag, the speed-regulating motor drives the cleaning frame to rotate. Since the cleaning frame has a polygonal cross-section, its rotation will periodically beat the filter bag, causing the filter bag to vibrate. At the same time, the bottom of the filter bag is fixed by the pull rope and connectors. Under the action of vibration, the dust adhering to the surface of the filter bag is shaken off, and the shaken-off dust falls to the slag discharge port.

[0007] Preferably, the feeder includes a housing fixedly connected to the bottom of the slag discharge port, a feed plate is provided inside the housing, a drive motor is fixedly connected to one end of the housing, and the feed plate is connected to the output shaft of the drive motor; the drive motor drives the feed plate to rotate inside the housing, so as to evenly transport and discharge the dust falling from the slag discharge port, and the feed speed can be adjusted by controlling the speed of the drive motor.

[0008] Preferably, a dust suppression device for processing magnesia-carbon bricks in an electric furnace further includes: a dust accumulation collection module installed on the side of the filter bag, used to capture the sound wave attenuation characteristics of the filter bag being vibrated by the cleaning frame, and to generate a dust accumulation coefficient through a control module; an adhesion strength collection module installed on the power supply circuit of the speed-regulating motor, used to monitor the load current fluctuation of the speed-regulating motor in real time, and to generate an adhesion strength coefficient through a control module; the control module performs a comprehensive analysis of the generated dust accumulation coefficient and adhesion strength coefficient to generate an evaluation coefficient, determines whether it is necessary to enhance the dust removal intensity, compares the evaluation coefficient with a pre-set reference threshold, and controls the working state of the dust removal mechanism based on the comparison result.

[0009] Preferably, the output and input ends of the dust accumulation collection module and the output and input ends of the adhesion strength collection module are electrically connected to the input and output ends of the control module, respectively, and the output end of the control module is electrically connected to the input end of the speed regulating motor.

[0010] Preferably, the steps by which the control module controls the working state of the dust removal mechanism based on the comparison results are as follows:

[0011] The dust accumulation acquisition module collects and captures the acoustic attenuation characteristics of the filter bag being vibrated by the cleaning rack; the adhesion strength acquisition module monitors the load current fluctuation of the speed-regulating motor; the control module calculates the dust accumulation coefficient, adhesion strength coefficient, and evaluation coefficient; if the evaluation coefficient is less than the set threshold: maintain the current parameters; if the evaluation coefficient is greater than or equal to the set threshold: increase the vibration frequency and the torque of the speed-regulating motor.

[0012] Preferably, the logic for generating the dust accumulation coefficient is as follows:

[0013] The actual acoustic amplitude of the dust removal mechanism at each time point within time T is obtained through the dust accumulation acquisition module; the dust accumulation coefficient is calculated based on the dispersion of the actual acoustic amplitude relative to the average acoustic amplitude.

[0014] Preferably, the logic for generating the adhesion strength coefficient is as follows:

[0015] The actual operating current of the speed-regulating motor of the dust removal mechanism at each moment within time T is obtained by the adhesion strength acquisition module; the adhesion strength coefficient is calculated based on the fluctuation of the actual operating current relative to the average current.

[0016] Preferably, the logic for generating the evaluation coefficients is as follows:

[0017] The control module generates evaluation coefficients by making dynamic priority decisions based on the nonlinear coupling relationship between the dust accumulation coefficient and the adhesion strength coefficient through preset weighting coefficients.

[0018] The present invention also provides a dust reduction process for processing magnesia-carbon bricks for electric furnaces, comprising the following steps:

[0019] Step 1: Dust-laden gas enters the dust collector tangentially through the inlet pipe, forming a rotating airflow inside the dust collector. Some of the larger dust particles are thrown against the inner wall of the dust collector by centrifugal force and fall to the slag discharge port. The remaining dust-laden gas rises and is filtered through the filter bags. The dust is trapped on the surface of the filter bags. The filtered clean gas is discharged through the outlet under the action of the fan.

[0020] Step 2: Start the motor to drive the polygonal cleaning frame to rotate. During the rotation, the filter bag is periodically tapped and vibrated, and the dust adhering to the surface of the filter bag is shaken off to the slag discharge port.

[0021] Step 3: The dust falling from the slag discharge port is conveyed and discharged through the feeder.

Detailed Implementation

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0035] Reference Figures 1-6 A dust removal device for processing magnesia-carbon bricks in an electric furnace includes a dust collection box 1. A partition 2 is fixedly connected inside the dust collection box 1. An air outlet 3 is opened on the partition 2. A filter bag 4 covering the air outlet 3 is fixedly connected to the bottom of the partition 2. An air inlet pipe 5 and an air outlet pipe 6 are provided on the outer wall of the dust collection box 1. The air inlet pipe 5 and the air outlet pipe 6 are located below and above the partition 2, respectively. A fan 7 is fixedly connected to the other end of the air outlet pipe 6. The direction of the air inlet pipe 5 is tangent to the dust collection box 1. A slag discharge port 12 is provided at the bottom of the dust collection box 1. A feeder is connected to the slag discharge port 12.

[0036] In use, dust-laden gas enters the dust collector 1 tangentially through the inlet pipe 5, forming a rotating airflow inside the dust collector 1. Some of the larger dust particles are thrown against the inner wall of the dust collector 1 by centrifugal force and fall to the slag discharge port 12. The remaining dust-laden gas is filtered upward through the filter bag 4, and the dust is trapped on the surface of the filter bag 4. The filtered clean gas is discharged through the outlet 3 and the outlet pipe 6 under the action of the fan 7. The collected dust is discharged from the slag discharge port 12 through the feeder. This can effectively reduce the amount of dust accumulation on the surface of the filter bag 4, thereby delaying the clogging time of the filter bag 4.

[0037] Furthermore, a dust removal mechanism is provided inside the filter bag 4. The dust removal mechanism includes a cleaning frame 9 with a polygonal cross-section. A speed-regulating motor 8 is fixedly connected to the top inner wall of the dust collector 1. The cleaning frame 9 is connected to the output shaft of the speed-regulating motor 8. The filter bag 4 is fitted onto the cleaning frame 9. The bottom of the filter bag 4 is connected to a pull rope 10 through multiple connectors 11. The other end of the pull rope 10 is fixed to the inner wall of the dust collector 1 through the connectors 11.

[0038] During use, in the dust suppression process, the filter bag 4 will adhere to the cleaning frame 9 due to negative pressure, forming a polygonal shape. When cleaning the filter bag 4, the speed-regulating motor 8 drives the cleaning frame 9 to rotate. Because the cleaning frame 9 has a polygonal cross-section, its rotation will periodically tap the filter bag 4, causing the filter bag 4 to vibrate (e.g., ...). Figure 3 In the process, the filter bag 4 is formed from a polygon into a circle. At the same time, the bottom of the filter bag 4 is fixed by the pull rope 10 and the connector 11. Under the action of vibration, the dust adhering to the surface of the filter bag 4 is shaken off, and the shaken dust falls to the slag discharge port 12.

[0039] The feeder includes a housing 13 fixedly connected to the bottom of the slag discharge port 12, a feed plate 15 is provided inside the housing 13, a drive motor 14 is fixedly connected to one end of the housing 13, and the feed plate 15 is connected to the output shaft of the drive motor 14.

[0040] In use, the drive motor 14 drives the feeding plate 15 to rotate inside the housing 13, which evenly conveys and discharges the dust falling from the slag discharge port 12. The feeding speed can be adjusted by controlling the speed of the drive motor 14.

[0041] In another embodiment, a dust suppression device for processing magnesia-carbon bricks in an electric furnace further includes:

[0042] The dust accumulation collection module 16 is installed on the side of the filter bag 4 to capture the sound wave attenuation characteristics of the cleaning frame 9 vibrating the filter bag 4, and generates the dust accumulation coefficient through the control module 18.

[0043] The adhesion strength acquisition module 17 is installed on the power supply circuit of the speed-regulating motor 8. It is used to monitor the load current fluctuation of the speed-regulating motor 8 in real time and generate the adhesion strength coefficient through the control module 18.

[0044] It should be noted that the dust accumulation acquisition module 16 can be an acoustic vibration sensor or other device that can capture the acoustic attenuation characteristics of the cleaning rack 9 vibrating the filter bag 4 in real time, the adhesion strength acquisition module 17 can be a current sensor or other device that can monitor the load current fluctuation of the speed-regulating motor 8 in real time, and the control module 18 is an embedded controller (such as the STM32 series) that integrates data fusion algorithms. Therefore, the dust accumulation acquisition module 16, the adhesion strength acquisition module 17, and the control module 18 are not specifically limited here and can be selected according to actual needs.

[0045] In use, the control module 18 performs a comprehensive analysis of the generated dust accumulation coefficient and adhesion strength coefficient to generate an evaluation coefficient, determine whether it is necessary to enhance the dust removal intensity, compare the evaluation coefficient with a pre-set reference threshold, and control the working state of the dust removal mechanism based on the comparison result.

[0046] The output and input terminals of the dust accumulation acquisition module 16 and the adhesion strength acquisition module 17 are electrically connected to the input and output terminals of the control module 18, respectively. The output terminal of the control module 18 is electrically connected to the input terminal of the speed regulating motor 8.

[0047] In another embodiment, the control module 18 performs a comprehensive analysis of the generated dust accumulation coefficient and adhesion strength coefficient to generate an evaluation coefficient, determines whether the dust removal intensity needs to be increased, and compares the evaluation coefficient with a preset reference threshold. The execution steps for controlling the working state of the dust removal mechanism based on the comparison result are as follows:

[0048] Real-time detection: The dust accumulation acquisition module 16 collects and captures the sound wave attenuation characteristics of the cleaning rack 9 and the vibrating filter bag 4; the adhesion strength acquisition module 17 monitors the load current fluctuation of the speed-regulating motor 8;

[0049] Coefficient calculation:

[0050] Dust accumulation coefficient: quantifies the thickness and uniformity of the dust layer on the surface of the filter bag. It reflects the accumulation state by the degree of energy attenuation of sound waves in the dust layer. The larger the Dδ, the lower the air permeability of the filter bag → the higher the system wind resistance → the higher the fan energy consumption → the dust cake may locally clump together → the more you need to increase the rapping intensity; the smaller the Dδ, the cleaner the filter bag surface → maintain the regular dust cleaning cycle.

[0051] The logic for generating the dust accumulation coefficient is as follows:

[0052] S1. The dust accumulation collection module 16 acquires the actual acoustic wave amplitude at different times within time T during the cleaning of filter bag 4 by the dust cleaning mechanism. The actual acoustic wave amplitude acquired at time i within time T is calibrated as... , i = 1, 2, 3, ..., p, where i is a positive integer;

[0053] S2. Calculate the dust accumulation coefficient. The expression for the calculation is:

[0054]

[0055] In the formula, denoted as the average acoustic amplitude over time T; p represents the number of samples taken over time T.

[0056] Adhesion strength coefficient: Characterizes the bonding force between the powder cake and the filter bag fibers. It reflects the mechanical resistance through the dispersion of the load current of the cleaning motor. The larger the Iσ, the more likely it is that high humidity dust or tar will adhere to the filter bag, which may cause "bag clogging" failure, requiring increased vibration force or extended cleaning time. The smaller the Iσ, the easier it is for the powder cake to fall off, which may reduce the cleaning frequency.

[0057] The logic for generating the adhesion strength coefficient is as follows:

[0058] S1. The actual operating current of the speed-regulating motor 8 at different times within time T during the cleaning of filter bag 4 is obtained through the adhesion strength acquisition module 17. The actual operating current obtained at time n within time T is calibrated as... n = 1, 2, 3, ..., k, where n is a positive integer;

[0059] S2. Calculate the adhesion strength coefficient. The expression for the calculation is:

[0060]

[0061] In the formula, Let be the average current over time T; k is the number of samples over time T.

[0062] Evaluation coefficient: This coefficient is a priority indicator that comprehensively assesses the risk of dust accumulation (Dδ) and the risk of mechanical overload (Iσ), resolving conflicting decisions between the two types of parameters. For example, if the dust is thick but loose (Dδ↑, Iσ↓), only routine dust removal is needed; if the dust is thin but strongly adhered (Dδ↓, Iσ↑), enhanced rapping (to prevent caking) is required. The control module 18 generates the evaluation coefficient based on the nonlinear coupling relationship between the dust accumulation coefficient and the adhesion strength coefficient, using preset weighting coefficients for dynamic priority decision-making. The control module 18 then performs a formulaic analysis based on the following formula:

[0063]

[0064] In the formula, r1 and r2 are weighting coefficients. The influence of the adhesion strength coefficient on the evaluation coefficient is higher than that of the dust accumulation coefficient. For example, r1=1.2 and r2=1.5 (the specific values ​​need to be dynamically determined based on experimental data).

[0065] Dynamic adjustment: If Rg<0.8: Maintain current parameters; if Rg≥0.8: Activate enhanced mode: increase vibration frequency by 30%, shorten dust removal cycle by 50%, and increase torque of speed-regulating motor 8 by 20%.

[0066] In addition, the present invention also provides a dust reduction process for processing magnesia-carbon bricks for electric furnaces, comprising the following steps:

[0067] Step 1: Dust-laden gas enters the dust collector tangentially through the inlet pipe, forming a rotating airflow inside the dust collector. Some of the larger dust particles are thrown against the inner wall of the dust collector by centrifugal force and fall to the slag discharge port. The remaining dust-laden gas rises and is filtered through the filter bags. The dust is trapped on the surface of the filter bags. The filtered clean gas is discharged through the outlet under the action of the fan.

[0068] Step 2: Start the motor to drive the polygonal cleaning frame to rotate. During the rotation, the filter bag is periodically tapped and vibrated, and the dust adhering to the surface of the filter bag is shaken off to the slag discharge port.

[0069] Step 3: The dust falling from the slag discharge port is conveyed and discharged through the feeder.

[0070] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
