Description

Technical Field

[0001] This utility model belongs to the technical field of removing slag layer from the surface of waste chromium corundum bricks, and specifically relates to a device for removing slag layer from the surface of waste chromium corundum bricks. Background Technology

[0002] The current preparation process of recycled dense composite chromium corundum mainly involves raw material processing, molding, and sintering. The specific method is as follows: using waste chromium corundum from the kiln as raw material, the slag layer on the surface of the waste chromium corundum bricks is first removed manually. Then, the waste chromium corundum bricks are processed into granules or powder through crushing and screening. Subsequently, the waste chromium corundum brick raw material is wet-mixed and granulated. Finally, it is sintered at a high temperature of 1550~1650℃ to form new dense composite chromium corundum. Because the surface slag layer of the chromium corundum brick is a complex multiphase system, it mainly includes the main crystalline phase dominated by Al2O3-Cr2O3 solid solution, the secondary phase dominated by magnesium chromium spinel (MgO·Cr2O3), the glassy phase dominated by silicate glass, and small amounts of impurity phases such as FeO, MgO, and SiO2. The formation mechanism of the slag layer on the surface of waste chromium corundum bricks: In high-temperature operating environments, the chromium corundum brick material and molten slag undergo complex physicochemical reactions through physical penetration and chemical reaction mechanisms. For the process of regenerating dense composite chromium corundum, if the slag layer on the surface of waste chromium corundum bricks is not removed, it will lead to a decrease in the key performance indicators (bulk density, apparent porosity, and thermal shock stability) of the regenerated dense composite chromium corundum.

[0003] In existing technologies, the removal of the slag layer on the surface of waste chromium corundum bricks is done manually by scraping or grinding. Because the slag layer on the surface of waste chromium corundum bricks is highly dense and hard, for slag layers that cannot be removed manually, further grinding with a grinding machine is required to remove the slag layer. This results in low efficiency and high labor costs in removing the slag layer from the surface of waste chromium corundum bricks. Based on the above-mentioned technical deficiencies in existing technologies, the inventors have developed a device for removing the slag layer from the surface of waste chromium corundum bricks, which can effectively solve the aforementioned technical problems.

[0011] The hydraulic cylinder is fixedly connected to the oil outlet of the hydraulic oil solenoid valve on the output end of the hydraulic station via a high-pressure oil pipe, and the hydraulic oil solenoid valve is fixedly connected to the PLC control module via a signal line.

[0012] The dimensions of the working plate and the lifting base plate are smaller than the size of the lower opening of the enclosed box.

[0013] The inclined chute includes a chute body, which is U-shaped with folded edges on the front and rear sides. Fixing plates are fixedly installed on the front and rear sides of the left end of the chute body. The rear side of the left end of the fixing plate on the rear side of the chute body is fixed to the inner right side of the vertical side plate of the support. The front side of the left end of the fixing plate on the front side of the chute body is fixed to the inner right side of the vertical fixing plate. The height of the chute body is lower than the height of the conveyor belt.

[0014] The upper end face of the collection box is equipped with lifting lugs at the middle position of the left and right sides. The overhead crane or lifting device can use the lifting lugs to lift the chromium corundum bricks after the slag layer has been removed to the crushing process for the next crushing operation.

[0015] The working process of this device for removing the slag layer from the surface of waste chromium corundum bricks is as follows: First, the operator turns on the conveyor via a control switch, and also turns on the stepper motor of the closed cleaning mechanism via another control switch, causing it to rotate. Then, the operator places the chromium corundum bricks removed from the kiln onto the conveyor belt, with the slag layer facing upwards. When the conveyor transports the chromium corundum bricks to the lower position of the proximity switch on the side of the vertical cylinder of the pushing mechanism, the proximity switch senses the position signal of the chromium corundum bricks and transmits the acquired position signal to the PLC control module. The PLC control module then sends a start control command to the solenoid valve of the vertical cylinder of the pushing mechanism, causing the double telescopic rod of the vertical cylinder to open. As the vertical cylinder extends, the magnetic ring on the double telescopic rod moves to the position of magnetic switch A at the lower rear of the vertical cylinder. Due to the magnetic force of the ring, magnetic switch A is opened. At this time, magnetic switch A transmits the received position signal of the vertical cylinder's telescopic rod to the PLC control module. Simultaneously, the PLC control module sends a closing control command to the solenoid valve of the vertical cylinder, stopping the vertical cylinder's movement (at this point, the chromium corundum brick is transported to the right side of the vertical cylinder, and the sliding body is located in the middle of the left side of the chromium corundum brick). Simultaneously, the PLC control module sends an opening control command to the solenoid valve of the horizontal cylinder. The double telescopic rods of the transverse cylinder begin to extend to the right, causing the pusher plate to move the chromium corundum brick to the right. When the magnetic ring on the double telescopic rods of the transverse cylinder moves to the position of magnetic switch B in the middle of the upper guide rail on the front side of the transverse cylinder, the magnetic force of the magnetic ring opens magnetic switch B and sends a position signal to the PLC control module. At this time, the chromium corundum brick is pushed onto the working plate of the lifting mechanism (at this time, the pusher plate is on the left side of the working plate, and the chromium corundum brick is in the middle of the working plate). Simultaneously, the PLC control module sends an opening control command to the hydraulic oil solenoid valve of the lifting mechanism hydraulic cylinder, and the telescopic rod of the hydraulic cylinder begins to extend. Under the push of the telescopic rod of the hydraulic cylinder, the lifting base plate and the working plate are moved together. The guide cylinder rises along the symmetrically arranged guide posts. When the guide cylinder moves to the position of the guide post's limit plate, the slag layer on the upper surface of the chromium corundum brick on the working plate contacts the bottom of the cleaning blade of the closed cleaning mechanism (at this time, the working plate is flush with the bottom end face of the closed box). At this time, under the rotation of the stepper motor, the drive shaft is driven to rotate at high speed around the axis of the rotary bearing. The high-speed rotating cleaning blades rotate and cut away the slag layer on the upper surface of the chromium corundum brick. During the high-speed rotation process of cutting away the slag layer on the upper surface of the chromium corundum brick, dust will inevitably be generated. At this time, the induced draft fan of the bag filter draws the dust generated by the rotational cutting of the slag layer into the bag filter through the dust collection pipe and filters it.After the slag layer on the upper surface of the chromium corundum brick is removed by rotation (according to the rotation removal time set by the PLC control module), the PLC control module sends an opening control command to the hydraulic solenoid valve of the hydraulic cylinder. The telescopic rod of the hydraulic cylinder retracts to its initial position (i.e., the working plate is flush with the conveyor belt of the conveyor). At the same time, the PLC control module sends another opening control command to the solenoid valve of the transverse cylinder of the pushing mechanism. The double telescopic rod of the transverse cylinder continues to extend to the right, driving the pushing plate to move to the right. During the movement of the pushing plate, it pushes the chromium corundum brick that has been rotated and removed to continue moving to the right. When the double telescopic rod of the transverse cylinder extends... When the retractable magnetic ring moves to the position of magnetic switch B at the right end of the lower guide rail on the front side of the transverse cylinder, the magnetic force of the magnetic ring opens magnetic switch B and obtains the position information of the double telescopic rod of the transverse cylinder. At this time, the chromium corundum brick is pushed onto the chute body of the inclined chute and falls into the collection box. After the slag layer on the surface of the first chromium corundum brick is removed by rotation, the above-mentioned action of rotating and removing the slag layer on the surface of the first chromium corundum brick is repeated to continuously remove the slag layer on the surface of the chromium corundum brick. When the collection box is full of the removed chromium corundum bricks, it can be lifted to the crushing process using an overhead crane or hoisting device.

[0016] The beneficial effects of this utility model are as follows: by setting up a conveyor, support, closed cleaning mechanism, pushing mechanism, lifting mechanism, inclined chute and collection box, and through the automated linkage control of the PLC control module, the removal efficiency of the slag layer on the surface of waste chromium corundum bricks is greatly improved and the labor cost is reduced.

Detailed Implementation

[0023] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model provides a device for removing the impregnation residue layer on the surface of waste chromium corundum bricks:

[0025] like Figure 1 , 2 As shown in Figures 3 and 4, the closed cleaning mechanism 4 is fixedly installed at the upper front side of the support 3. The closed cleaning mechanism 4 can perform rotary cutting to remove the slag layer of the chromium corundum brick 2 in a closed state. The closed cleaning mechanism 4 includes a closed box 41, which is a hollow square shape with the upper and four sides closed and the lower part open. The rear side of the closed box 41 is fixedly connected to the front side of the vertical plate 33 of the support 3. The motor mounting bracket 42 is fixedly installed at the middle of the upper rear side of the closed box 41, and the stepper motor 43 is fixedly installed at the front side of the motor mounting bracket 42. The drive shaft 44 is fixedly installed at the lower part of the bottom power output shaft of the stepper motor 43, and the rotary bearing 45 is fixedly installed on the closed box. At the upper center of the enclosed box 41, the drive shaft 44 extends through the inner ring of the slewing bearing 45 into the interior of the enclosed box 41, and the drive shaft 44 is fixed to the inner ring of the slewing bearing 45; the cleaning blade disc 46 is fixedly installed at the bottom of the drive shaft 44, the cleaning blade disc 46 is circular, and the fan-shaped bosses 47 are fixedly installed at the bottom of the cleaning blade disc 46. The fan-shaped bosses 47 are arranged at equal angles around the circumference of the cleaning blade disc 46, and a cleaning blade 48 is fixedly installed on the bottom edge of each fan-shaped boss 47; the dust removal pipe 49 is fixedly installed at the upper middle part of the rear side of the enclosed box 41, the dust removal pipe 49 is connected to the interior of the enclosed box 41, and the outer end of the dust removal pipe 49 is fixedly connected to the bag filter.

[0026] With the aforementioned enclosed box 41, after the working plate 66 of the lifting mechanism 6 rises into the enclosed box 41, the lower opening of the enclosed box 41 is sealed by the working plate 66. This effectively prevents dust from overflowing when the slag layer on the surface of the chromium corundum brick 2 is removed by rotary cutting with the cleaning knife 48, thus reducing dust pollution to the environment.

[0027] The aforementioned arrangement of stepper motor 43, drive shaft 44, rotary bearing 45, cleaning cutter disc 46, fan-shaped boss 47, and cleaning blade 48, under the rotation of stepper motor 43, drives drive shaft 44 to rotate around the center of rotary bearing 45, thereby driving cleaning cutter disc 46 to rotate at high speed, and using cleaning blade 46 to rotary cut and remove the slag layer on the surface of chromium corundum brick 2.

[0028] The dust collection pipe 49, along with the bag filter, allows the dust generated during the rotary cutting process to be transported to the bag filter, thus achieving dust collection.

[0029] like Figure 1 , 2 As shown in Figures 3 and 4, the pushing mechanism 5 is fixedly installed at the middle left position of the upper part of the support 3. The pushing mechanism 5 is used to push the chromium corundum brick 2 to the conveying position or to push the chromium corundum brick 2 to the unloading position. The pushing mechanism 5 includes an L-shaped fixing plate 51, which is horizontally fixedly installed at the middle left position of the longitudinal mounting plate 34 of the support 3. The reinforcing block 52 is fixedly installed at the front and rear positions of the connection between the L-shaped fixing plate 51 and the longitudinal mounting plate 34. The vertical cylinder 53 is fixedly installed on the left end face of the L-shaped fixing plate 51. The slide rail 55 is fixedly installed at the middle right side face of the vertical cylinder 53. The slide groove 55 is opened at the middle left side face of the sliding body 45. The sliding body 54 is L-shaped. The slide groove 55 of the sliding body 54 is fitted onto the slide rail 55. The double telescopic rod of the vertical cylinder 53 is fixed to the bottom of the sliding body 54 by nuts. Cylinder 57 is fixedly installed at the bottom right side of sliding body 54. Push plate 58 is fixedly installed at the right end of double telescopic rod of horizontal cylinder 57 by nuts. Push plate 58 is fixedly installed perpendicular to horizontal cylinder 57. There are two magnetic switches A59. One is fixedly installed at the upper part of the left side guide rail that runs vertically through the rear side of vertical cylinder 53. The other is fixedly installed at the lower part of the right side guide rail that runs vertically through the rear side of vertical cylinder 53. There are two magnetic switches B510. One is fixedly installed at the middle of the upper guide rail on the front side of horizontal cylinder 57. The other is fixedly installed at the right end of the lower guide rail on the front side of horizontal cylinder 57. Proximity switch 511 is fixedly installed at the bottom middle of the left side of vertical cylinder 53. Proximity switch 511 is fixedly connected to PLC control module through signal line.

[0030] The aforementioned arrangement of the vertical cylinder 53, sliding body 54, slide rail 55, and slide groove 56 in the pushing mechanism 5, along with the two magnetic switches A59 located on the rear side of the vertical cylinder 53, allows for the sensing and positioning of the specific extension and retraction positions of the double telescopic rods of the vertical cylinder 53. This enables the lifting and lowering movement of the horizontal cylinder 57. On one hand, this positions the pushing plate 58 against the side of the chromium corundum brick 2. On the other hand, it prevents the vertical cylinder 53 and the horizontal cylinder 57 from interfering with the chromium corundum brick 2 conveyed on the conveyor 1.

[0031] The aforementioned arrangement of the horizontal cylinder 57, pusher plate 58, and magnetic switch B510 in the pushing mechanism 5 allows for control of the specific position of the pusher plate 58. This is achieved by using the magnetic switch B510 located in the middle of the upper guide rail on the front side of the horizontal cylinder 57 and the magnetic switch B510 located at the right end of the lower guide rail on the front side of the horizontal cylinder 57. On one hand, when the chromium corundum brick 2 is pushed to its right end position by the conveyor belt of the conveyor 1, it is automatically pushed onto the working plate 66 of the lifting mechanism 6 under the automatic control of the PLC control module. On the other hand, after the slag layer on the surface of the chromium corundum brick 2 is removed by the cleaning knife 48, the magnetic switch B510 located at the right end of the lower guide rail on the front side of the horizontal cylinder 57 senses and positions the telescopic rod of the horizontal cylinder 57, allowing the removed chromium corundum brick 2 to be pushed to the inclined chute 8, where it slides into the collection box 9 using its own gravity.

[0032] The aforementioned setting of proximity switch 511, along with the automatic control of the PLC control module, enables the automatic opening and closing of the feeding mechanism 5.

[0033] like Figure 3 and 4 As shown, the lifting mechanism 6 is fixedly installed in the middle of the bracket 3. The lifting mechanism 6 is used to push the chromium corundum brick 2 to move up or down. The lifting mechanism 6 includes guide columns 61, which are symmetrically fixedly installed in the middle of the upper part of the base plate 32. A limit plate 63 is fixed on the upper part of the guide columns 61. The guide cylinder 62 is vertically fixedly installed on the left and right sides of the lifting base plate 65. The guide columns 61 extend through the guide cylinder 62 to the upper part of the lifting base plate 65. A working plate 66 is provided on the upper part of the lifting base plate 65. The lifting base plate 65 and the working plate 66 are fixedly connected by four connecting columns 67. The connecting columns 67 are located at the four corners between the lifting base plate 65 and the working plate 66.

[0034] The aforementioned arrangement of the guide column 61, guide cylinder 62, and limiting plate 63 in the lifting mechanism 6 ensures stable guidance for the lifting of the lifting base plate 65 and working plate 66 during the process of the hydraulic cylinder 64 pushing the lifting base plate 65 and working plate 66 to rise and fall. At the same time, the limiting plate 63 can prevent the lifting base plate 65 and working plate 66 from rising excessively and falling off.

[0035] The aforementioned arrangement of the lifting base plate 65, the working plate 66, and the connecting column 67 allows the lifting base plate 65 and the working plate 66 to be fixedly connected into an integral structure. On the one hand, this provides stable support for the chromium corundum brick 2; on the other hand, when the chromium corundum brick 2 on the working plate 66 rises into the interior of the enclosed box 41, the working plate 66 is flush with the lower opening end face of the enclosed box 41. By using the working plate 66 and the enclosed box 41 to form an enclosed space, it can effectively prevent dust from overflowing due to the rotary cutting and removal of the slag layer on the surface of the chromium corundum brick 2, thus preventing environmental pollution.

[0036] The hydraulic cylinder 64 can be used to press the chromium corundum brick 2 on the upper part of the working plate 66 against the bottom of the cleaning cutter disc 46, and the high-speed rotating cleaning cutter 48 can be used to remove the slag layer on the surface of the chromium corundum brick 2 by rotary cutting.

[0037] like Figure 1 and 2 As shown, the vertical fixing plate 7 is fixedly installed at the bottom front side of the support 3. The height of the vertical fixing plate 7 is greater than the height of the conveyor 1. The inclined chute 8 is inclinedly installed inside the support 3 and the vertical fixing plate 7. The left rear side of the fixing plate 82 on the rear side of the chute body 81 is fixed to the right inner side of the vertical side plate 33 of the support 3. The left front side of the fixing plate 82 on the front side of the chute body 81 is fixed to the right inner side of the vertical fixing plate 7.

[0038] The main purpose of this arrangement is to securely fix the inclined chute 8 to the inner side of the fixing plate 7 and the vertical side plate 33.

[0039] like Figure 1 , 2 As shown, the inclined chute 8 is inclinedly installed inside the support 3 and the vertical fixing plate 7. The inclined chute 8 is used for free-fall conveying of chromium corundum bricks 2 after the slag layer has been removed. The inclined chute 8 includes a chute body 81, which is U-shaped with folded edges on the front and rear sides. The fixing plate 82 is fixedly installed on the front and rear sides of the left end of the chute body 81. The rear side of the left end of the fixing plate 82 on the rear side of the chute body 81 is fixed to the inner side of the right side of the vertical side plate 33 of the support 3. The front side of the left end of the fixing plate 82 on the front side of the chute body 81 is fixed to the inner side of the right side of the vertical fixing plate 7. The height of the chute body 81 is lower than the height of the conveyor belt of the conveyor 1.

[0040] The above-mentioned inclined chute 8 is used to allow the chromium corundum brick 2, after the surface slag layer has been removed, to slide into the collection box 9 by the gravity of the chromium corundum brick 2 itself.

[0041] like Figure 1 and 2 As shown, the collection box 9 is placed at the bottom right side of the inclined chute 8. The collection box 9 is a hollow square shape with an open top and closed sides and bottom. Lifting lugs are provided at the middle of the left and right sides of the upper end face of the collection box 9.

[0042] The above-mentioned method involves installing lifting lugs at the middle position of the left and right sides of the upper end face of the collection box 9, so that the chromium corundum brick 2 after the slag layer has been removed can be lifted to the crushing process by using an overhead crane or lifting device.

[0043] The PLC control module, the solenoid valves of the vertical cylinder 53 and the horizontal cylinder 57, and the hydraulic solenoid valve of the hydraulic cylinder 64 described in this utility model are all within the scope of existing technology. At the same time, the automated control of the PLC control module is also within the scope of existing technology, which is fully known to those skilled in the art. Therefore, its working principle and control method will not be described in detail.

[0044] like Figure 1-5As shown, the working process of this device for removing the slag layer from the surface of waste chromium corundum bricks is as follows: First, the operator turns on the conveyor 1 via a control switch, and turns on the stepper motor 43 of the closed cleaning mechanism 4 via a control switch, putting it into a rotating state; then, the operator places the chromium corundum bricks 2 removed from the kiln onto the conveyor belt of the conveyor 1, with the slag layer of the chromium corundum bricks 2 facing upwards. When the conveyor 1 transports the chromium corundum bricks 2 to the lower position of the proximity switch 511 on the side of the vertical cylinder 53 of the pushing mechanism 5, the proximity switch 511 senses... After receiving the position signal of the chromium corundum brick 2, the acquired position signal of the chromium corundum brick 2 is transmitted to the PLC control module. The PLC control module sends a start control command to the solenoid valve of the vertical cylinder 53 of the pushing mechanism 5. The double telescopic rod of the vertical cylinder 53 begins to extend. When the magnetic ring on the double telescopic rod of the vertical cylinder 53 moves to the position of the magnetic switch A59 at the lower rear side of the vertical cylinder 53 as the telescopic rod extends, the magnetic force of the magnetic ring causes the magnetic switch A59 at the lower rear side of the vertical cylinder 53 to be in the open state. At this time, the magnetic switch A59 at the lower rear of the vertical cylinder 53 transmits the received position signal of the telescopic rod of the vertical cylinder 53 to the PLC control module. Simultaneously, the PLC control module sends a closing control command to the solenoid valve of the vertical cylinder 53, causing the vertical cylinder 53 to stop moving (at this time, the chromium corundum brick 2 is transported to the right side of the vertical cylinder 53, and the sliding body 54 is located in the middle of the left side of the chromium corundum brick 2). At the same time, the PLC control module sends an opening control command to the solenoid valve of the horizontal cylinder 57, causing the horizontal cylinder 57 to double telescopic... The rod begins to extend to the right, causing the pusher plate 58 to push the chromium corundum brick 2 to move to the right. When the magnetic ring on the double telescopic rod of the transverse cylinder 57 moves to the position of the magnetic switch B510 in the middle of the upper guide rail on the front side of the transverse cylinder 57, the magnetic force of the magnetic ring causes the magnetic switch B510 to open and send a position signal to the PLC control module. At this time, the chromium corundum brick 2 is pushed onto the working plate 66 of the lifting mechanism 6 (at this time, the pusher plate 58 is in the left position of the working plate 66, and the chromium corundum brick 2 is in the middle position of the working plate 66).At the same time, the PLC control module sends an opening control command to the hydraulic oil solenoid valve of the hydraulic cylinder 64 of the lifting mechanism 6. The extension rod of the hydraulic cylinder 64 begins to extend. Under the push of the extension rod of the hydraulic cylinder 64, the lifting base plate 35 and the working plate 66 are raised along the guide cylinder 61 symmetrically arranged on the left and right sides using the guide cylinder 62. When the guide cylinder 62 moves up to the position of the limit plate 63 of the guide cylinder 61, the slag layer on the upper surface of the chromium corundum brick 2 on the working plate 66 contacts the bottom of the cleaning blade 46 of the sealing cleaning mechanism 4 (at this time, the working plate 66 is flush with the bottom end face of the sealing box 41). At this time, the stepper motor 43 rotates... Under the action of rotation, the drive shaft 44 is driven to rotate at high speed around the axis of the slewing bearing 45, driving the cleaning cutter disc 46 to rotate. The high-speed rotating cleaning cutter 48 removes the slag layer on the upper surface of the chromium corundum brick 2. During the high-speed rotation process of removing the slag layer on the upper surface of the chromium corundum brick 2, dust will inevitably be generated. At this time, the induced draft fan of the bag filter draws the dust generated by the rotation of the slag layer into the bag filter through the dust collection pipe 49 for filtration and dust removal. After the rotation of the slag layer on the upper surface of the chromium corundum brick 2 is completed (according to the rotation removal time set by the PLC control module), the PLC control module sends a hydraulic... The hydraulic solenoid valve of cylinder 64 sends an open control command, and the telescopic rod of hydraulic cylinder 64 retracts to its initial position (i.e., the working plate 66 is flush with the conveyor belt of conveyor 1). At the same time, the PLC control module sends another open control command to the solenoid valve of the transverse cylinder 57 of the pushing mechanism 5. The double telescopic rod of the transverse cylinder 57 continues to extend to the right, driving the pushing plate 58 to move to the right. During the movement of the pushing plate 58, it pushes the rotary cut-off chromium corundum brick 2 to continue moving to the right. When the magnetic ring of the double telescopic rod of the transverse cylinder 57 moves to the right end of the lower guide rail on the front side of the transverse cylinder 57... When the magnetic switch B510 is in position, the magnetic force of the magnetic ring causes the magnetic switch B510 to open, and the position information of the double telescopic rod of the transverse cylinder 57 is obtained. At this time, the chromium corundum brick 2 is pushed onto the chute body 81 of the inclined chute 8 and falls into the collection box 9. After the slag layer on the surface of the first chromium corundum brick 2 is removed by rotation, the above-mentioned action of rotating and removing the slag layer on the surface of the first chromium corundum brick 2 is repeated, so that the slag layer on the surface of the chromium corundum brick 2 can be continuously removed. When the collection box 9 is full of the removed chromium corundum brick 2, the collection box 9 can be lifted to the crushing process using an overhead crane or hoisting device.
