Technical Field

[0001] The present invention relates to the technical field of metallurgical solid waste treatment, and more specifically, to a device for collaborative treatment and resource utilization of the entire industrial chain of metallurgical solid waste. Background Art

[0002] The efficient resource utilization of metallurgical solid waste (such as blast furnace slag, steel slag, copper slag, etc.) is the core link for the metallurgical industry to achieve green transformation. The current mainstream metallurgical solid waste treatment processes include steps such as crushing, melting, sorting, and forming. Among them, the continuous transportation of high-temperature molten materials is the key to connecting each link. Due to its advantages such as good airtightness and high transportation efficiency, screw conveyors are widely used in the transfer of molten slag.

[0003] Existing screw conveyors usually include structures such as screw blades. Currently, it is difficult to detect the wear of the screw blades of the screw conveyor, resulting in out-of-control dynamic balance and serious vibration. Moreover, it is difficult to compensate for the dynamic balance of the current screw conveyor, relying on manual surfacing repair or counterweight adjustment after shutdown. Summary of the Invention

Liquid metal is stored in the liquid storage cavities, and the volume of the liquid metal accounts for 80% of the liquid storage cavity.

[0009] Further, connection channels are connected to the liquid storage cavities.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Refer to Figures 1-9 , a collaborative processing and resource utilization device for the whole industrial chain of metallurgical solid waste, including a metallurgical solid waste conveyor 1, and further including:

[0035] A transmission shaft 2 and a screw blade 3. A monitoring module is arranged inside the transmission shaft 2 and the screw blade 3. The monitoring module is used to monitor the wear condition of the screw blade 3 during the working process. A compensation module is also arranged inside the transmission shaft 2. The compensation module is used to compensate the equipment according to the wear condition of the screw blade 3;

[0036] During use, metallurgical solid waste enters the metallurgical solid waste conveyor 1 through the feed port. The metallurgical solid waste conveyor 1 transports the metallurgical solid waste through the transmission shaft 2 and the screw blade 3. The metallurgical solid waste is discharged from the discharge port. During the working process of the screw blade 3, the screw blade 3 will be worn by the metallurgical solid waste. The monitoring module monitors the wear condition of the screw blade 3 in real time. When the wear reaches the set value, the compensation mechanism is triggered in time, and compensation is carried out through the compensation module to maintain the dynamic balance of the equipment. When the compensation times of the screw blade 3 reach the maintenance period, the equipment needs to be shut down for maintenance.

[0037] Refer to Figure 3, the monitoring module includes a piezoelectric torque sensor 4 and a fiber Bragg grating sensor 6. The piezoelectric torque sensor 4 is installed between the root of the helical blade 3 and the transmission shaft 2 and is evenly installed along the helical direction of the helical blade 3. An installation groove 5 is provided on the helical blade 3, and the fiber Bragg grating sensor 6 is installed in the installation groove 5. The fiber Bragg grating sensor 6 is sealed in the installation groove 5 through a laser cladding alloy layer. The fiber Bragg grating sensor 6 is arranged in a Fibonacci sequence along the helical direction of the helical blade 3. By arranging the fiber Bragg grating sensors 6 in a Fibonacci sequence, the detection blind area can be reduced. The alloy sealing layer needs to be heat-resistant to ensure the stability of the sensor under high-temperature working conditions. The piezoelectric torque sensor 4 detects the torque fluctuation at the root of the helical blade 3 to capture abnormal load signals. The fiber Bragg grating sensor 6 quantifies the wear thickness of the helical blade 3 through the wavelength shift amount. Through the collaborative monitoring of multiple sensors, the key wear areas along the entire length of the helical blade 3 are covered.

[0038] Refer to Figure 4 and Figure 5 , multiple sets of liquid storage chambers are arranged along the direction of the transmission shaft 2 inside the transmission shaft 2. Each set of liquid storage chambers includes twelve liquid storage cavities 7 evenly arranged in a circumferential array. The liquid storage cavity 7 stores liquid metal, and the volume of the liquid metal accounts for 80% of the liquid storage cavity 7. The liquid metal is a gallium-indium-tin eutectic alloy. When it is detected that a certain helical blade 3 is worn and needs to be compensated, the corresponding liquid storage chamber at that place is triggered, and the liquid metal in the liquid storage cavity 7 on the worn side is transferred to the liquid storage cavity 7 on the symmetric side to adjust the mass distribution of the transmission shaft 2 and offset the centrifugal force caused by the wear of the helical blade 3. Based on the principle of momentum moment balance, the dynamic balance of the equipment is restored.

[0039] Refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 , a connecting channel 8 is communicated with each liquid storage cavity 7. Multiple connecting channels 8 are communicated through an annular channel 9. Adjacent two annular channels 9 are communicated through a transverse channel 10. Multiple electromagnetic pumps 11 are arranged inside the transmission shaft 2. A first connecting pipe 12 communicated with the corresponding liquid storage cavity 7 is installed on the electromagnetic pump 11, and a second connecting pipe 13 communicated with the corresponding connecting channel 8 is installed on the electromagnetic pump 11. When it is necessary to transfer liquid metal for compensation, the corresponding electromagnetic pump 11 is started. The electromagnetic pump 11 extracts liquid metal from the corresponding liquid storage cavity 7 through the first connecting pipe 12 and discharges it into the corresponding connecting channel 8. The liquid metal enters the corresponding liquid storage cavity 7 through the annular channel 9 and the connecting channel 8 to form a reverse mass moment. By setting the transverse channel 10, when the liquid metal amount in a certain liquid storage chamber is insufficient, the liquid metal can be transferred across the liquid storage chambers through the transverse channel 10.

[0040] Refer to Figure 7, a plurality of micro motors 14 are installed in the transmission shaft 2. The output shaft of the micro motor 14 is fixedly connected with a plugging ball 15. The plugging ball 15 is located between the connecting channel 8, the annular channel 9 and the transverse channel 10. A T-shaped channel 16 is opened on the plugging ball 15. When the micro motor 14 is started to drive the plugging ball 15 to rotate, the plugging ball 15 drives the T-shaped channel 16 to rotate, so that the T-shaped channel 16 rotates to a proper angle to connect the proper channels, or the connecting channel 8 can be closed by rotating the plugging ball 15 to a proper angle to prevent the liquid metal in the liquid storage cavity 7 from flowing out.

[0041] Refer to Figure 8 , a first cooling channel 17 and a second cooling channel 18 are opened in the transmission shaft 2. The first cooling channel 17 and the second cooling channel 18 are located outside the liquid storage cavity 7. The first cooling channel 17 and the second cooling channel 18 are communicated through a connecting cavity 19. The outer wall of the transmission shaft 2 is rotatably connected with a first hollow ring block 20 communicated with the first cooling channel 17, and the outer wall of the transmission shaft 2 is rotatably connected with a second hollow ring block 21 communicated with the second cooling channel 18. A coolant is arranged in the first cooling channel 17 and the second cooling channel 18. The first hollow ring block 20 and the second hollow ring block 21 are connected with an external circulation pump through a connecting pipe. The coolant sequentially passes through the first hollow ring block 20, the first cooling channel 17, the connecting cavity 19, the second cooling channel 18 and the second hollow ring block 21 through the external circulation pump, and the coolant can cool the liquid metal in the liquid storage cavity 7 to keep the liquid metal below the set temperature.

[0042] Refer to Figure 8 , two bearing seats 22 are arranged in the metallurgical solid waste conveyor 1. The transmission shaft 2 is arranged between the two bearing seats 22. A vibration sensor 23 is installed in the bearing seat 22. The vibration of the transmission shaft 2 is monitored in real time through the vibration sensor 23, and the vibration data is fed back to the control system in real time. When the threshold value is exceeded, compensation optimization is triggered, and the compensation parameters are fine-tuned through data.

[0043] A method for collaborative treatment and resource utilization of the whole industrial chain of metallurgical solid waste includes the following steps:

[0044] S1: The solid waste generated by metallurgy is transported through the metallurgical solid waste conveyor 1. The solid waste enters from the feed inlet of the metallurgical solid waste conveyor 1, and the solid waste is transported by the rotation of the transmission shaft 2 and the spiral blade 3, and the solid waste leaves from the discharge outlet.

[0045] S2: During the process of the spiral blade 3 transporting the solid waste, the piezoelectric torque sensor 4 detects the torque fluctuation at the root of the spiral blade 3 in real time, the fiber Bragg grating sensor 6 monitors the wear thickness of the blade according to the Fibonacci sequence distribution, and the vibration sensor 23 feeds back the dynamic balance state in real time.

[0046] S3: Calculate the liquid metal compensation amount based on the wear data, and drive the liquid metal to transfer from the liquid storage cavity 7 on the worn side to the symmetric liquid storage cavity 7 through the electromagnetic pump 11;

[0047] S4: Circulate the cooling medium through the first cooling channel 17 and the second cooling channel 18 to maintain the temperature of the liquid metal;

[0048] S5: After the compensation is completed, continue to monitor the spiral blade 3 until the maintenance cycle of the spiral blade 3 is reached, and perform maintenance on the entire equipment and the spiral blade 3.
