Description

Technical Field

[0001] This utility model relates to the technical field of roasting furnace maintenance devices, specifically to a maintenance device for a fire channel wall. Background Technology

[0002] The fire channel wall is an important component of the roasting furnace. It primarily forms the fire channel, allowing flames and hot gases to flow within and heat the materials. The fire channel wall is a wall structure built of refractory materials (such as refractory bricks, refractory mortar, and refractory fibers). Located inside the roasting furnace, it supports the fire channel, isolates the flames and hot gases, and allows them to flow along a predetermined path within the fire channel, uniformly heating the materials. During use, the fire channel wall must not only possess high strength and stability to withstand the high temperatures of the flames and hot gases without deformation or cracking, but also excellent thermal insulation properties to reduce heat loss and protect other parts of the roasting furnace from the effects of high temperatures.

[0003] However, in actual use, the fire channel wall is eroded and worn by factors such as flames, hot air, and materials, which can cause changes in the wall structure. This can easily lead to raw blocks not being able to be loaded and cooked blocks not being able to be discharged. It can also cause the fire channel to be blocked, affecting the quality of the carbon blocks and seriously affecting the normal operation of the roasting furnace. To solve this problem, it is necessary to maintain the entire fire channel wall regularly. However, due to the large area of ​​the entire wall, the maintenance cycle is long and the insulation effect of the repaired wall is not ideal. Therefore, it is necessary to use corresponding maintenance devices to improve the quality of maintenance.

[0004] In the prior art, for example, a patent application with application number CN201320421890.4 discloses a calcining furnace fire channel wall repair device, comprising an open square box, with V-shaped openings on opposite sides of the upper part of the square box, and locking bolts at the V-shaped openings; a circular hole at the bottom of the square box is fixedly connected to the upper part of a circular tube, the lower part of the circular tube is inserted into the upper part of a flexible connecting cylinder, and the lower part of the flexible connecting cylinder is connected to the upper part of a suction pipe; the upper and lower parts of the flexible connecting cylinder are respectively provided with hose clamps. This calcining furnace fire channel wall repair device utilizes the suction function of a multi-functional overhead crane for unblocking, effectively solving the problem of material leakage and blockage in damaged fire channel walls during the low-temperature preheating stage and other different low-temperature zones. It is convenient to maintain, has high work efficiency, significantly reduces damage to the calcining furnace fire channel wall, reduces the adverse effects of fire channel blockage, and can directly repair and unblock fire channels in the preheating zone, reducing the labor intensity of workers.

[0005] Although this device can solve the problem of material leakage and blockage in the damaged fire channel wall, it can only be used for repairing and clearing the fire channel and is not suitable for repairing the fire channel wall of the roasting furnace. It cannot provide a favorable repair work space for the workers repairing the fire channel wall of the roasting furnace. Therefore, a repair device needs to be designed specifically for the problem of fire channel wall repair.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the background technology of this disclosure and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0027] This application provides a fire wall maintenance device, which solves the problem that existing fire wall maintenance devices cannot be used for fire wall maintenance. To better understand the technical solution of this application, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0028] This example discloses a maintenance device for a fire channel wall; see [link to relevant documentation]. Figures 1 to 7 The device includes a support base 2, symmetrically mounted wheels 3 at the bottom of the support base 2, a load-bearing plate 1 mounted on the support base 2, a plurality of positioning studs 4 symmetrically fixed on the load-bearing plate 1, and a repair platform 5 sleeved on the positioning studs 4.

The rotating shaft 32 is rotatably mounted on the support base 2, and a rotating gear 33 is also sleeved and fixed in the middle of the rotating shaft 32. The bottom of the support base 2 is also provided with a bottom groove 21, which corresponds to the position of the rotating gear 33. A drive screw 6 is rotatably mounted in the bottom groove 21. A drive motor 61 is also fixed on the outside of the support base 2. The drive screw 6 meshes with the rotating gear 33, and the drive motor 61 is connected to the outer end of the drive screw 6.

[0030] The repair platform 5 also includes a calibration component 51 symmetrically mounted on the outside of the repair channel 52, multiple snap-fit ​​sleeves 54 rotatably mounted on the positioning block 55, and a storage frame 53 mounted on the positioning block 55. The snap-fit ​​sleeves 54 are fitted onto the positioning studs 4 and have corresponding internal threads. A snap-fit ​​gear 541 connected to the snap-fit ​​sleeves 54 is also provided on the back of the positioning block 55. The repair platform 5 also includes a central gear 56 symmetrically mounted on the back of the positioning block 55 and a drive gear 57 mounted between the central gears 56. The central gears 56 mesh with the snap-fit ​​gears 541, and the drive gears 57 mesh with the central gears 56. A gear motor 571 connected to the drive gear 57 is also mounted on the positioning block 55. The calibration assembly 51 includes a limiting screw 513 rotatably mounted on the outside of the repair channel 52, a screw catch 5131 symmetrically sleeved on the limiting screw 513, a limiting rod 512 rotatably mounted on the screw catch 5131, a connecting block 5121 rotatably mounted on the free end of the limiting rod 512, and a calibration plate 511 fixed on the connecting block 5121. The limiting screw 513 is also provided with symmetrical forward and reverse threads. The calibration assembly 51 also includes a driven bevel gear 514 mounted on one end of the limiting screw 513 and a driving bevel gear 515 rotatably mounted on the repair channel 52. The driving bevel gear 515 meshes with the driven bevel gear 514. A control turntable 516 connected to the driving bevel gear 515 is also provided inside the repair channel 52.

[0031] When implementing the device of this application, the device is placed between the fire walls that need to be repaired. Then, refractory materials such as refractory bricks used for repair are stacked in the storage frame 53. The repair worker stands in the repair passage 52. Next, the gear motor 571 is started to raise the repair platform 5. The specific working principle is as follows: the gear motor 571 drives the drive gear 57 to rotate, which in turn drives the intermediate gear 56 to rotate synchronously. The intermediate gear 56 drives the locking gear 541 to rotate synchronously. When the locking gear 541 rotates, the locking sleeve 54 rotates synchronously. Its internal thread, limited by the positioning stud 4, drives the positioning block 55 to move upward, thereby causing the repair platform 5 to rise synchronously. When the repair platform 5 rises to the required repair height, the gear motor 571 is turned off, and the repair platform 5 stops rising. Then, the repair worker manually rotates... The control turntable 516 drives the active bevel gear 515 to rotate, which in turn drives the driven bevel gear 514 to rotate. The driven bevel gear 514 drives the limiting screw 513 to rotate synchronously. Under the action of the bidirectional thread on the limiting screw 513, the screw locking block 5131 moves towards the center of the limiting screw 513. During the displacement, the calibration plate 511 moves outward continuously due to the limiting rod 512, until a portion of the lower part of the calibration plate 511 abuts against the side wall of the fire channel wall. At this point, the rotation of the control turntable 516 stops. The repair worker can then quickly lay the refractory bricks on the fire channel wall. Due to the limiting effect of the calibration plate 511, the refractory bricks are neatly stacked on the fire channel wall, ensuring work quality while improving repair efficiency and effectively shortening the maintenance cycle. During repair, to further improve efficiency, the repair worker can also operate the bidirectional calibration plate 511 to repair both sides of the fire channel wall, which is simple and practical to operate. After the calibration plate 511 has been repaired in the contact area, the control turntable 516 is rotated in the reverse direction to reset the calibration plate 511. Then, the drive motor 61 is started, driving the drive screw 6 to rotate. The rotating drive screw 6 drives the rotating shaft 32 to rotate via the rotating gear 33. The rotating shaft 32, in conjunction with the synchronizing rod 31, drives the rotating wheel 3 to rotate synchronously, thereby achieving the displacement of the device. When the device has moved to the next area to be repaired, the drive motor 61 is turned off, the device stops moving, and the repair worker can reuse the calibration plate 511 to continue the repair work. For areas to be repaired at different heights, the repair worker can also adjust the height of the repair platform 5 by controlling the gear motor 571. Combined with the rotation of the rotating wheel 3, repair work can be carried out in any area, which is not only flexible and practical but also improves repair efficiency and shortens the repair cycle. Furthermore, the motors used in the device of this application are all existing technologies, and their specific working principles will not be elaborated in this technical solution.
