Description

Technical Field

[0001] The utility model relates to the technical field of metallurgy, in particular to a device for stably discharging slag by tilting a leaching tank. Background Art

[0002] In the intermittent leaching process of triple leaching and quadruple washing in the vanadium sesquioxide leaching process, the waste slag and returned slag after the tank leaching generates qualified liquid need to be poured into the reversible large belt below through the tilting of the key equipment, the leaching tank. The reversible large belt runs bidirectionally to discharge the slag, and the returned slag enters the roasting furnace for the cyclic closed-loop operation of the external transportation of the waste slag. The stable operation of the leaching tank is directly related to the normal production of the main line of the entire roasting system. Previously, in order to smoothly discharge the slag, when the leaching tank was tilted to discharge the slag, the operator used the impact inertia of the tilting of the leaching tank to discharge the slag downward. The tilting impact of the leaching tank was large and the stability was poor. During the process of tilting and discharging the slag, the elastic vibration impact of the leaching tank was obvious, causing greater damage to the rack cylinder, fixed bearing seat and transmission shaft of the leaching tank of the tank leaching operation equipment. The unstable tilting and discharging of the slag by the leaching tank not only caused the uneven discharge of the slag from the leaching tank to be too large, but also the phenomenon that the slag frequently jammed the reversible large belt below and affected the production. In addition, the elastic vibration impact often caused major equipment accidents such as the cracking and explosion of the cylinder body of the rack cylinder, the overturning of the foundation of the fixed bearing seat and the fracture of the transmission shaft of the leaching tank. The occurrence of equipment accidents such as explosion, overturning and fracture also posed a great threat to the personal safety of the on-site operators.

[0003] The electro-hydraulic rotary actuator with precise angle control disclosed in CN 104454771 A, the rack cylinder mainly includes a cylinder barrel, a piston rod, pistons at both ends of the piston rod, gland covers at both ends of the cylinder barrel. Teeth are arranged on the piston rod, and a gear meshes with the teeth of the piston rod. A magnetostrictive displacement sensor is penetrated through one of the two gland covers, a magnetic ring is connected to the piston close to the gland cover, and the detection end of the magnetostrictive displacement sensor is penetrated into the magnetic ring. The linear displacement analog signal provided by the magnetostrictive displacement sensor is converted into the angle of the gear swing through PLC control. This prior art proposes to precisely control the angle of the gear swing by using the magnetostrictive displacement sensor.

[0004] The environmental protection type metallurgical slag cooling treatment system and process disclosed in CN 108559811 B, the slag pot tilter includes a tilting mechanism vertical plate and a slag pot locking mechanism; the slag pot locking mechanism includes a fixed large gear, a small gear and a locking pin. The fixed large gear is fixedly installed inside the bearing seat of the slag pot tilter. The two small gears are respectively hinged to the tilting mechanism vertical plate through rotary pairs and respectively mesh with the fixed large gear and the locking pin. Both sides of the locking pin are connected to the tilting mechanism vertical plate through linear pairs. When the slag pot is locked, no power mechanism is required and it is locked naturally. This prior art proposes to realize the locking of the slag pot by using the fixed large gear, two small gears and the locking pin.

[0005] A clean, heat extraction, dry treatment system and process for high-temperature metallurgical slag disclosed in CN 111518971 B. The slag ladle tilter consists of a tilter mounting frame, a tilter hydraulic motor, a slag ladle frame, and a spring clamp. The two ends of the main shaft of the slag ladle frame are fixed on the tilter mounting frame through bearing seats, and one end is connected to the drive shaft of the tilter hydraulic motor. The tilter mounting frame is respectively placed on both sides of the annular rotating platform group, and the spring clamp is used to fix the slag ladle in the slag ladle frame. The prior art proposes to achieve arbitrary adjustment of the tilting speed and tilting angle of the slag ladle through stepless speed regulation of the tilter hydraulic motor.

[0006] Currently, the tilting devices and methods in the metallurgical or chemical enterprises in the industry are relatively single, mainly mechanical. However, the prior art does not give a suitable method and device to improve the equipment damage and personal injury caused by the impact of tilting and discharging slag in the leaching tank due to the unstable phenomenon of tilting and discharging slag in the leaching tank.

[0029] To make the objectives, technical solutions, and advantages of the present invention clearer and more understandable, the following further elaborates on the embodiments of the present invention in detail with reference to specific embodiments and the accompanying drawings.

[0030] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two entities or parameters with the same name but different identities. It can be seen that "first" and "second" are only for the convenience of expression and should not be construed as a limitation on the embodiments of the present invention. This will not be elaborated one by one in the subsequent embodiments.

[0031] The present invention provides a device for stable slag discharge by tilting a leaching tank, as Figure 1 shown, which includes a fixed structure, a locking hook device 3, a rack cylinder 4, a tilting device, a variable-frequency shock vibrator 9, a hydraulic system, and a terminal buffer 14. The locking hook device 3, the rack cylinder 4, and the terminal buffer 14 are fixedly arranged on the fixed structure. The tilting device is rotatably arranged on the fixed structure through the rack cylinder 4. The locking hook device 3 is releasably fixedly connected to the tilting device. The variable-frequency shock vibrator 9 is arranged on the tilting device. The terminal buffer 14 is used to reduce the impact of the tilting device when the tilting device tilts. The rack cylinder 4 is connected to the hydraulic system and is controlled by the hydraulic system.

[0032] In some embodiments, the fixing structure includes a column 1 and an I-beam foundation 6. The I-beam foundation 6 is horizontally arranged, and the column 1 is fixedly arranged on the I-beam foundation 6 and perpendicular to the I-beam foundation 6. The hook device 3 is fixedly arranged on one side of the column 1, and the length direction of the hook device 3 is parallel to the length direction of the I-beam foundation 6. The rack cylinder 4 is fixedly arranged on the I-beam foundation 6 adjacent to the hook device 3, and the terminal buffer 14 is arranged on the I-beam foundation 6 and away from the hook device 3 and the rack cylinder 4.

[0033] In some embodiments, the fixing structure includes two columns 1 and two I-beam foundations 6. The two I-beam foundations 6 are horizontally arranged and parallelly aligned. One column 1 is fixedly arranged on each I-beam foundation 6, and the two columns 1 are respectively perpendicular to the corresponding I-beam foundations 6. The hook device 3 is fixedly arranged on one side of one column 1, and the length direction of the hook device 3 is parallel to the length direction of the I-beam foundation 6 corresponding to the column 1. The rack cylinder 4 is fixedly arranged on the corresponding I-beam foundation 6 adjacent to the hook device 3. The terminal buffers 14 are respectively arranged on the two I-beam foundations 6.

[0034] In some embodiments, the base of the rack cylinder 4 is fixed on the I-beam foundation 6 by the rack cylinder fixing bolts 13 and the reinforcing U-shaped clamps 5, so as to firmly fix the rack cylinder 4 on the I-beam foundation 6. The rack cylinder fixing bolts 13 and the reinforcing U-shaped clamps 5 improve the stability of the rack cylinder 4, such that when the tipping device rotates through the rack cylinder 4, the firmness of the rack cylinder 4 relative to the I-beam foundation 6 is improved, and the impact of the tipping of the tipping device on the rack cylinder 4 is avoided.

[0035] In some embodiments, the tipping device includes a leaching tank 7, a leaching tank transmission shaft 8 and a mechanical stop 2. The mechanical stop 2 is arranged outside the leaching tank 7. The leaching tank transmission shaft 8 is centrally arranged on the leaching tank 7 and fixedly connected to the leaching tank 7. One end of the leaching tank transmission shaft 8 is fixedly connected to the central axis of the rack cylinder 4, such that the rotation of the central axis of the rack cylinder 4 drives the rotation of the leaching tank transmission shaft 8, and further drives the rotation of the leaching tank 7. Similarly, when the central axis of the rack cylinder 4 stops rotating, the leaching tank transmission shaft 8 stops rotating, and the leaching tank 7 also stops rotating.

[0036] In some embodiments, such as Figure 1As shown, the leaching tank 7 includes a bottom wall and four side walls arranged in sequence around the bottom wall and connected in sequence. The four side walls are the first side wall 17, the second side wall 18, the third side wall 19, and the fourth side wall in sequence. Among them, the first side wall 17 faces the rack cylinder 4. A locking structure 20 is provided on the first side wall 17. The locking structure 20 matches the hook device 3. The hook device 3 can be hooked together with the locking structure 20 or separated from the locking structure 20. When the hook device 3 is hooked together with the locking structure 20, the leaching tank 7 is perpendicular to the I-beam foundation 6 and stationary relative to the rack cylinder 4. The leaching tank 7 is firmly hooked to the column 1 through the hook device 3. The hook device 3, as a safety device, hooks the leaching tank 7 to the column 1 before the leaching tank 7 is full of slag and does not tip over, thereby preventing the leaching tank 7 from accidentally tipping over due to misoperation.

[0037] In some embodiments, the mechanical stop 2 is provided on the first side wall 17 of the leaching tank 7. When the leaching tank 7 is tilted in place, the mechanical stop 2 touches and combines with the terminal buffer 14, thereby reducing the downward turning impact of the leaching tank 7 and enabling the leaching tank 7 to stay stably.

[0038] In some embodiments, a variable-frequency shock vibrator 9 is provided on the leaching tank 7. The variable-frequency shock vibrator 9 has different vibration frequencies. When the leaching tank 7 stays at different tilting angles, the leaching tank 7 can be vibrated by the variable-frequency shock vibrator 9 using a vibration frequency matching the tilting angle of the leaching tank 7. By adjusting the different vibration frequencies of the variable-frequency shock vibrator 9 to vibrate the leaching tank 7 for slag discharging, the uniformity and stability of the slag discharging of the leaching tank 7 are ensured, and the phenomena of excessive and uneven slag discharging amount of the leaching tank 7 and frequent dead pressing of the slag on the reversible large belt below affecting production are avoided. During the process of the leaching tank 7 tilting for slag discharging, the vibration frequency of the variable-frequency shock vibrator 9 changes from large to small, that is, the vibration frequency of the variable-frequency shock vibrator 9 decreases as the tilting degree of the leaching tank 7 increases, so that the slag in the leaching tank 7 vibrates and stably slides down to the reversible large belt below, avoiding the phenomena of large elastic impact vibration of the slag and unstable slag discharging amount during the existing leaching tank 7 tilting for slag discharging relying on the inertial impact of downward turning. The variable-frequency shock vibrator 9 improves the existing inertial blanking of the leaching tank 7 to shock blanking, and improves the safety factor of the leaching tank 7 tilting for blanking.

[0039] In some embodiments, the variable-frequency shock vibrator 9 is provided outside the second side wall 18 of the leaching tank 7. When the leaching tank 7 tilts downward for slag discharging, the variable-frequency shock vibrator 9 vibrates the second side wall 18, so that the slag slides down in a vibrating manner on the vibrating second side wall 18, improving the uniformity and stability of the slag falling onto the reversible large belt below the leaching tank 7.

[0040] In some embodiments, the tipping device includes a rotating contact block 10 which is arranged on the leaching tank transmission shaft 8. The rotating contact block 10 is fixed to the end of the leaching tank transmission shaft 8 at one end which is fixedly connected to the central axis of the rack cylinder 4, and the rotating contact block 10 rotates with the rotation of the leaching tank transmission shaft 8.

[0041] In some embodiments, one end of the rotating contact block 10 is arranged at the center of the end of the leaching tank transmission shaft 8, and the other end is located outside the end of the leaching tank transmission shaft 8. For example, the rotating contact block 10 can be in the shape of a pointer, a sector or a triangle.

[0042] In some embodiments, a displacement sensor 21 is arranged on the rack cylinder 4. As Figure 2 shown, the displacement sensor 21 is arranged on one side of the rack cylinder 4 and is used for accurately positioning the movement of the rack cylinder 4. The design of the rack cylinder 4 and the displacement sensor 21 mainly ensures that the piston of the rack cylinder 4 can be accurately displaced, reduces the operation impact caused by excessive displacement of the rack of the rack cylinder 4, and at the same time extends the service life of the rack cylinder 4. Since the displacement of the rack of the rack cylinder 4 is related to the impact of the leaching tank 7 and the mass of the leaching tank 7 is large, the greater the rack displacement, the greater the impact of the leaching tank 7. When the rack displacement can be accurately controlled, the rack displacement can be reduced, thereby reducing the impact of the leaching tank 7.

[0043] In some embodiments, a rack cylinder damper 11 is arranged on the rack cylinder 4. The rack cylinder damper 11 is used to damp the rack cylinder 4 and reduce the buffering of the leaching tank 7. The rack cylinder damper 11 is arranged at the end face of the rack cylinder 4 corresponding to the piston of the rack cylinder 4. When the leaching tank 7 stays at any tipping position, the oil circuit supplied to the rack cylinder 4 stops, and the piston of the rack cylinder 4 continues to move due to inertia. At this time, the rack cylinder damper 11 restricts the movement of the piston, prevents the piston from impacting the end cover of the rack cylinder 4 due to inertia when the rack cylinder 4 stops moving, maintains the buffering of the rack cylinder 4, and further ensures the stability of the rack cylinder 4. Therefore, during the downward tipping process of the leaching tank 7, the rack cylinder damper 11 can buffer and stabilize the rack cylinder 4 when the leaching tank 7 stays at any tipping position angle.

[0044] In some embodiments, a rack cylinder stroke limit 12 is arranged on the rack cylinder 4. The rack cylinder stroke limit 12 is arranged adjacent to the leaching tank transmission shaft 8 and is configured to stop the rotation of the rotating contact block 10 when it touches the rotating contact block 10 of the tipping device in rotation. When the rotating contact block 10 touches the rack cylinder stroke limit 12, the rack cylinder stroke limit 12 transmits an electrical signal indicating the position where the rotating contact block 10 arrives to the hydraulic system, and the hydraulic system controls the oil circuit supplied to the rack cylinder 4 not to work, so that the rack cylinder 4 stops working, thereby keeping the leaching tank 7 stationary. In some embodiments, the rack cylinder stroke limit 12 can be a sensor.

[0045] In some embodiments, there are two rack cylinder stroke limits 12, namely the first rack cylinder stroke limit and the second rack cylinder stroke limit, which are arranged on both sides of the rotary touch block 10 and are used to limit the rotary touch block 10 to the first position, the second position, and between the first position and the second position. When the rotary touch block 10 is in the first position, the rotary touch block 10 touches the first rack cylinder stroke limit, and the leaching tank 7 approaches the column 1. The first rack cylinder stroke limit avoids the collision between the leaching tank 7 and the column 1. When the rotary touch block 10 is in the second position, the rotary touch block 10 touches the second rack cylinder stroke limit, and the leaching tank 7 is in the state of being overturned in place and the leaching tank 7 stops overturning. At this time, the mechanical stop block 2 on the leaching tank 7 touches and combines with the terminal buffer 14, and the second rack cylinder stroke limit controls the leaching tank 7 to be overturned in place.

[0046] In some embodiments, the terminal buffer 14 can be a rubber block or a spring. The terminal buffer 14 has the function of spring buffering. When the leaching tank 7 is overturned in place, the terminal buffer 14 touches and combines with the mechanical stop block 2, avoiding the impact deformation of the I-beam foundation 6 by the leaching tank 7, reducing the in-place impact of the leaching tank 7, and enabling the leaching tank 7 to stay stably in place.

[0047] In some embodiments, as Figure 2 shown, the hydraulic system includes a proportional directional valve 15. The proportional directional valve 15 is a control element of the hydraulic system. The proportional directional valve 15 replaces the ordinary electromagnetic directional valve, avoiding the defects of large hydraulic shock, easy generation of more shocks, and the resulting unstable factors of the ordinary electromagnetic directional valve. The proportional directional valve 15 uses continuous and precise control of the valve opening to achieve the purpose of controlling the stability of the oil circuit of the rack cylinder 4, with higher precision than the ordinary electromagnetic directional valve. The proportional directional valve 15 precisely controls the movement of the rack cylinder 4 by controlling the stability of the oil circuit of the rack cylinder 4.

[0048] In some embodiments, the hydraulic system includes a pilot-operated check valve 16, which is used in combination with the proportional directional valve 15. The pilot-operated check valve 16 has the function of safely locking the rack cylinder 4. In the case of power failure or oil circuit bursting, it is used to lock the entire oil circuit, thereby locking the rack cylinder 4 at any angle, and further locking the leaching tank 7 at any position to prevent the leaching tank 7 from suddenly overturning. The design of the pilot-operated check valve 16 improves the stability of the rack cylinder 4, and further improves the overturning stability of the leaching tank 7.

[0049] In some embodiments, the hook locking device 3 includes a spring and a hook. The spring is connected to the hook and acts as a spring for the hook. After the leaching tank 7 automatically returns to its original position, the hook of the hook locking device 3 automatically hooks the locking structure 20 on the leaching tank 7 under the action of the spring. That is, when the leaching tank 7 is perpendicular to the I-beam foundation 6, the hook locking device 3 automatically hooks the locking structure 20 on the leaching tank 7 to prevent the leaching tank 7 from tipping down due to malfunction. The hook locking device 3 plays a role in protecting the safety of the leaching tank 7. When the leaching tank 7 is ready to tip, the hook of the hook locking device 3 can be manually pulled out to separate the hook from the locking structure 20, thereby releasing the leaching tank 7.

[0050] In some embodiments, the device for stably tipping and discharging slag of the leaching tank provided by the present utility model includes two columns 1, two I-beam foundations 6, a hook locking device 3, a rack cylinder 4, a variable-frequency shock vibrator 9, a leaching tank 7, a leaching tank transmission shaft 8, two terminal buffers 14, and a hydraulic system. The two columns 1 are respectively vertically and fixedly connected to the two I-beam foundations 6. The hook locking device 3 is arranged on one column 1, and the rack cylinder 4 is fixed on the I-beam foundation 6 perpendicular to the column 1 through a rack cylinder fixing bolt 13 and a reinforcing U-shaped clamp 5. A bearing seat (not shown) is arranged on the other I-beam foundation 6. A displacement sensor 21, two rack cylinder dampers 11, and two rack cylinder stroke limits 12 are arranged on the rack cylinder 4. A locking structure 20 and a mechanical stop 2 are arranged on the first side wall 17 of the leaching tank 7. The variable-frequency shock vibrator 9 is arranged on the second side wall 18 of the leaching tank 7. A mechanical stop 2 is arranged on the third side wall 19 of the leaching tank 7. The leaching tank transmission shaft 8 is fixedly arranged on the leaching tank 7 and one end thereof is fixedly connected to the central axis of the rack cylinder 4. The other end of the leaching tank transmission shaft 8 is rotatably arranged on the bearing seat. A rotating touch block 10 is fixed on the end of the leaching tank transmission shaft 8 fixedly connected to the central axis of the rack cylinder 4. The rotating touch block 10 is arranged between the two rack cylinder stroke limits 12. A terminal buffer 14 is arranged on each of the two I-beam foundations 6, and the two terminal buffers 14 respectively correspond to the two mechanical stops 2. The proportional reversing valve 15 and the hydraulic control one-way valve 16 of the hydraulic system are used in combination with the rack cylinder 4.

[0051] In some embodiments, for the device for stably tipping and discharging slag of the leaching tank provided by the present utility model, when the tipping device is in the normal state of not tipping, the tipping device is hooked to the column 1 through the hook locking device 3. When the tipping device is in the state of tipping in place, the tipping device is unlocked from the hook locking device 3 and the tipping device touches and combines with the terminal buffer 14. When the tipping device tips, the tipping angle of the tipping device is controlled by the rack cylinder 4.

[0052] The present utility model provides a method for stable slag discharging by tilting a leaching tank, using a device for stable slag discharging by tilting a leaching tank. By adopting a proportional reversing valve 15 and a pilot-operated check valve 16 of a hydraulic system and a displacement sensor 21 on a rack cylinder 4 to control the rack cylinder 4, and adopting a locking hook device 3, a variable-frequency vibration exciter 9 and a terminal buffer 14 to control the tilting device, the tilting device can tilt stably, discharge slag evenly and be hooked to a fixed structure.

[0053] The method for stable slag discharging by tilting the leaching tank of the present utility model, as Figure 3 shown, includes the following steps:

[0054] Step 1: Pull open the locking hook device 3, release the tilting device filled with slag from the fixed structure, and the tilting device slowly and stably turns downward under the restriction of the rack cylinder 4;

[0055] Step 2: During the process of the tilting device turning downward, precisely control the tilting angle of the tilting device and stably stop the tilting device through the proportional reversing valve 15, the pilot-operated check valve 16 and the displacement sensor 21. And when the tilting device stops at different tilting angles, adjust the vibration frequency of the variable-frequency vibration exciter 9 to vibrate and discharge slag from the tilting device;

[0056] Step 3: When the tilting device tilts in place, the tilting device touches and combines with the terminal buffer 14, and the tilting device stops stably, completing stable slag discharging;

[0057] Step 4: Reset the tilting device and hook the tilting device to the fixed structure through the locking hook device 3;

[0058] Step 5: After the tilting device is filled with slag, repeat the above steps 1 to 4.

[0059] In some embodiments, in step 1, the tilting device slowly and stably turns downward under the restriction of the rack cylinder 4, including: precisely controlling the displacement of the piston of the rack cylinder 4 through the displacement sensor 21 to precisely control the displacement of the rack of the rack cylinder 4, thereby precisely controlling the tilting of the tilting device.

[0060] In some embodiments, in step 1, precisely controlling the tilting of the tilting device includes precisely controlling the rotation of the leaching tank 7 of the tilting device.

[0061] In some embodiments, in step 2, precisely controlling the tilting angle of the tilting device and stably stopping the tilting device through the proportional reversing valve 15, the pilot-operated check valve 16 and the displacement sensor 21, including: precisely controlling the tilting of the tilting device through the displacement sensor 21, precisely controlling the action of the rack cylinder 4 to control the tilting angle of the tilting device by controlling the oil circuit of the rack cylinder 4 through the proportional reversing valve 15, and locking the rack cylinder 4 by using the pilot-operated check valve 16 in combination with the proportional reversing valve 15 to control the locking of the tilting device, so that the tilting device stops stably at different tilting angles.

[0062] In some embodiments, in step 2, adjusting the vibration frequency of the variable-frequency shock vibrator 9 to shock and discharge slag from the tipping device includes: using the variable-frequency shock vibrator 9 to shock the tipping device at a vibration frequency matching the tipping angle of the tipping device, so that the slag in the tipping device vibrates and falls.

[0063] In some embodiments, in step 2, when the tipping device stays at different tipping angles, the rack cylinder damper 11 provided on the rack cylinder 4 is used to damp the rack cylinder 4.

[0064] In some embodiments, in step 3, the tipping device is in place after tipping, including: the second rack cylinder stroke limit provided on the rack cylinder 4 touches the rotary touch block 10 provided on the tipping device.

[0065] In some embodiments, in step 3, the tipping device is in place after tipping, including: the mechanical stop 2 on the tipping device touches and combines with the terminal buffer 14 on the fixed structure.

[0066] In some embodiments, in step 4, resetting the tipping device includes: pushing the tipping device by an operator, and then the tipping device automatically rises and resets smoothly under the restriction of the rack cylinder 4.

[0067] The device and method for stable slag discharge of the tipping leaching tank of the present utility model enable the leaching tank 7 of the tipping device, during the tipping slag discharge process, not to use the inertial impact of the existing leaching tank 7 to discharge slag, but to combine the optimized mechanical buffer device of the leaching tank 7 with variable-frequency shock slag discharge and the displacement sensor 21, the proportional directional valve 15 and the hydraulic control check valve 16 of the hydraulic system to control the rack cylinder 4. During the tipping slag discharge process of the leaching tank 7, it ensures the stability of the fixed structure of the leaching tank 7, ensures that the leaching tank 7 can stay stably at any tipping angle position during tipping slag discharge and reduces impact, ensures that the downward elastic vibration impact of the leaching tank 7 during downward tipping is small, the downward slag discharge amount in the tank is uniform and the slag discharge is smooth. In addition, the device and method for stable slag discharge of the tipping leaching tank not only play a good protective role in the slag discharge of the leaching tank 7, but also play a role in ensuring the personal safety of on-site operators, ensuring the stable and efficient operation of the key tipping equipment of the enterprise.
