Description

Technical Field

[0001] The invention relates to the technical field of roasting furnaces, and in particular to a fire channel wall maintenance device. Background Art

[0002] The open anode baking furnace is a high-temperature kiln currently used for baking carbon anode products at home and abroad. This type of carbon anode product is used in aluminum electrolytic cells in the electrolytic aluminum industry as anodes of metal aluminum electrolytic cells. With the large-scale production capacity in recent years, large-scale anode baking furnaces are widely used. Whether it is investment cost or operating energy consumption, there are great advantages. However, large-scale also brings problems such as large deformation of the fire channel and low life. Among them, the deformation of the fire channel is the primary problem of large anode baking furnaces. The deformation of the fire channel mainly refers to the bending of the fire channel. On the one hand, it is caused by production process and refractory construction problems. On the other hand, it is due to the blockage of the vertical joints and expansion joints of the fire channel wall due to inadequate daily maintenance. Therefore, daily maintenance of the baking furnace is a very important routine operation.

[0003] In the current maintenance of the fire channel wall, the maintenance personnel install the furnace frame above the working area and stand on the furnace frame to maintain the fire channel wall, which is time-consuming, labor-intensive and inconvenient. In addition, there is a risk of falling during the maintenance process. The safety protection is only provided by the safety nets set on both sides of the roasting furnace to intercept the falling personnel, which is difficult to ensure the personal safety of the maintenance personnel. At the same time, the existing furnace frame is directly installed on the furnace chamber, which is easy to cause damage to the fire channel wall of the roasting furnace and affect the service life of the fire channel wall. Summary of the invention

[0004] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a fire channel wall maintenance device, which ensures the safety of the maintenance personnel by arranging a winch and a hanging basket to carry the maintenance personnel to enter the material box for operation, and by arranging a supporting mechanism, the structure of the maintenance device is stable, easy to move, and more efficient.

[0005] In order to achieve the above object, the main technical solutions adopted by the present invention include: A fire channel wall maintenance device, comprising a main beam, a supporting mechanism, a driving motor and a winch, wherein the supporting mechanism is divided into two groups, the main beam is arranged along the width direction of the roasting furnace, the two ends of the main beam are respectively connected to a group of supporting mechanisms, the bottom end of the supporting mechanism is provided with a roller, the driving motor is slidably connected to the main beam, the winch is connected to the driving motor, the driving motor is used to drive the winch to move along the main beam, the winch is provided with a hanging basket, the winch is used to control the hanging basket to move up and down, and the hanging basket is used to load maintenance personnel into the material box; The supporting mechanism includes an inclined column and a supporting beam. There are two inclined columns, the top ends of which are connected to the main beam, and the bottom ends of which are connected to the rollers. The supporting beam is horizontally arranged, and the two ends of the supporting beam are respectively connected to the middle of the two inclined columns. The two inclined columns and the supporting beam together form an A shape.

[0006] By setting up a winch and a hanging basket to carry maintenance personnel into the material box for operation, the safety of the maintenance personnel is guaranteed. By setting up a supporting mechanism, the structure of the maintenance device is stable, easy to move, and more efficient.

[0007] By setting the rollers, the maintenance device can be manually moved, which is convenient and quick.

[0008] Furthermore, the inclined columns are made of channel steel, and the top ends of the two inclined columns are welded and connected, making the supporting mechanism more stable.

[0009] Furthermore, the main beam is made of I-beam.

[0010] Furthermore, it also includes a first steel cable, both ends of which are respectively connected to the upper part of the supporting mechanism, and the first steel cable is used to mount the power supply cable.

[0011] Furthermore, it also includes a second steel cable, which is arranged along the width direction of the roasting furnace. There are two second steel cables, which are horizontally parallel. Both ends of the second steel cables are connected to the lower part of the inclined column. The second steel cable is used to provide protection for maintenance personnel who have not entered the material box.

[0012] During maintenance operations, some personnel stand on the furnace surface to perform auxiliary maintenance work. The current safety net can only intercept personnel falling to the outside of the furnace surface, and there is still a risk of falling into the material box. By setting a second steel cable to block the inside of the furnace surface, even if they fall accidentally, they can pull the second steel cable back to their original position, ensuring the safety of the maintenance personnel.

[0013] Furthermore, the width of the hanging basket is 10-30 mm smaller than the width of the roasting furnace material box, and the length of the hanging basket is 0.8-1 m.

[0014] By properly setting the width of the hanging basket, the hanging basket can enter the deformed material box for maintenance work.

[0015] Furthermore, the drive motor and the winch are connected to the control system together, and a remote control is provided at the maintenance site. By connecting to the control system and providing a remote control at the maintenance site, maintenance work can be easily scheduled.

[0016] Furthermore, the main beam is 450-550 mm longer than the width of the roasting furnace chamber.

[0017] The beneficial effects of the present invention are: The fire channel wall maintenance device of the present invention ensures the safety of the maintenance personnel by arranging a winch and a hanging basket to carry the maintenance personnel to enter the material box for operation. By arranging a supporting mechanism, the maintenance device structure is stable, easy to move, and more efficient. In addition, a second steel cable is provided to block the inner side of the furnace surface. Even if the furnace surface personnel accidentally fall, they can return to their position by pulling the second steel cable, further ensuring the safety of the maintenance personnel.

[0023] By setting the roller 4, the manual moving maintenance device is realized, which is convenient and quick. Considering the high temperature of the furnace surface, a steel roller 4 is generally used, with a diameter of about 20 cm.

[0024] Specifically, the inclined column 2 is made of channel steel, and the top ends of two inclined columns 2 are welded and connected, so that the supporting mechanism is more stable.
