Description

Technical Field

[0001] The utility model relates to a drying device for heating and baking anode steel claws in aluminum electrolysis production, and particularly relates to a steel claw drying device. Background Art

[0002] Electrolytic aluminum is obtained by electrolysis in an aluminum electrolysis cell. Modern industrial production of electrolytic aluminum often adopts the cryolite-aluminum oxide molten salt electrolysis method. Molten cryolite is the solvent, aluminum oxide is the solute, a carbon body is used as the anode, and aluminum liquid is used as the cathode. After passing a strong direct current, an electrochemical reaction, that is, electrolysis, occurs at the two electrodes in the electrolysis cell at 950°C - 970°C.

[0003] The anode is an important component in an aluminum electrolysis cell. The anode includes an anode rod and anode steel claws, etc. Before the anode steel claws, the anode rod, and the anode assembly are cast, the anode steel claws need to be dipped in a graphite solution (a solution prepared by mixing graphite powder and kerosene). After dipping, drying treatment is required to avoid the generation of gas during the pouring of molten iron, which may cause the molten iron to explode and injure people.

[0004] In the prior art, a steel claw drying device is used to dry the steel claws. The steel claw drying device includes a device support. A plurality of nozzles are arranged on the device support at intervals in the left-right direction. The number of nozzles corresponds to the number of claw parts of the steel claws. For example, for a four-claw steel claw, there are four nozzles. The gas inlet end of the nozzle is connected to a gas pipeline, and an ignition needle is arranged beside the nozzle.

[0005] During use, the steel claws dipped with the graphite solution are lifted above the nozzles by a lifting tool. The ignition needle ignites, and the nozzles spray fire on the corresponding claw parts of the steel claws to dry the steel claws. The problems existing in the existing such steel claw drying device are as follows: When the steel claws are above the corresponding nozzles, since the graphite solution on the steel claws is not dry, the excess graphite solution on the steel claws will drip downward. The dripping graphite solution will fall on the nozzles and the ignition needle. The graphite solution falling on the ignition needle will cause the next ignition to fail, and the graphite solution falling on the nozzles is likely to accumulate and affect the size of the fire spraying, thereby affecting the drying efficiency. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a steel claw drying device to solve the technical problem that the graphite solution on the steel claws in the prior art drips onto the ignition needle and the nozzles, affecting the normal operation of the drying device.

[0007] To solve the above technical problem, the technical solution of a steel claw drying device in the utility model is as follows:

[0008] A steel claw drying device, comprising a device support. A rigid gas main pipe with a rotation axis extending in the left-right direction is rotatably assembled on the device support. The air inlet end of the rigid gas main pipe is used to be connected with a corresponding gas pipe. A main pipe fixing structure for fixing the position of the rigid gas main pipe after rotational adjustment is provided between the device support and the rigid gas main pipe. The steel claw drying device further includes a plurality of nozzles spaced along the left-right direction. Ignition needles are arranged beside the nozzles. The rigid gas main pipe has C-shaped pipe sections corresponding to the number of nozzles. The nozzles are connected to the C-shaped pipe sections through rigid gas branch pipes extending radially along the rigid gas main pipe. During the rotation of the rigid gas main pipe, there are a working position where the C-shaped pipe sections and the rigid gas branch pipes are in a vertical posture and a stowed position where the C-shaped pipe sections and the rigid gas branch pipes are in a horizontal posture.

[0009] Further, in the stowed position, the concave part of the C-shaped pipe section is used to avoid the graphite solution dripping from the corresponding steel claws.

[0010] Further, an installation sleeve with an axis extending in the left-right direction is fixed on the device support. Both ends of the rigid gas main pipe are rotatably assembled on the corresponding installation sleeves. The main pipe fixing structure includes a tightening screw threadedly connected to the corresponding installation sleeve for tightening the rigid gas main pipe.

[0011] Further, a rotary joint for rotatably connecting with the gas pipe is provided at the air inlet end of the rigid gas main pipe.

[0012] Further, the device support includes an upper support, a lower support and telescopic legs arranged between the upper support and the lower support. Travel wheels are arranged on the lower support. The rigid gas main pipe is rotatably assembled on the upper support.

[0013] Further, a front support and a rear support are arranged on the device support on the front and rear sides of the rigid gas main pipe. Wind shields are arranged at the upper ends of the front support and the rear support. Both the front support and the rear support include a plurality of support rods spaced along the left-right direction. During the rotation of the rigid gas branch pipe from the working position to the stowed position, the rigid gas branch pipe passes through the gap between two adjacent corresponding support rods.

[0014] Further, the support rods are telescopic rods with adjustable heights.

[0015] The beneficial effects of the present utility model are as follows: In the present utility model, the rigid gas main pipe is rotationally assembled on the device bracket. When the graphite solution can flow and drip on the steel claws, the rigid gas main pipe is rotated to the laid-down position. At this time, when the graphite solution on the steel claws drips, the dripping graphite solution will flow away through the concave part of the C-shaped pipe section and will not adhere to the nozzle and the ignition needle. When the graphite solution on the steel claws no longer flows and drips, the rigid gas main pipe is rotated to the working position, and then the rigid gas main pipe is fixed. At this time, the ignition needle ignites, and the flame ejected by the nozzle can dry the corresponding steel claws. The present utility model can prevent the dripping graphite solution from dripping onto the ignition needle and the nozzle, and avoid the dripping graphite solution from affecting the drying of the drying device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] For the convenience of understanding the present utility model, the present utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments. The preferred embodiments of the present utility model are shown in the drawings. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosed content of the present utility model more thorough and comprehensive.

[0023] It should be noted that unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the specification of the present utility model are only for the purpose of describing specific embodiments and are not used to limit the present utility model.

[0024] An embodiment of a steel claw drying device in the present utility model is as Figures 1 to 4 shown: It includes a device support 1. The device support includes an upper support 2, a lower support 3, and telescopic legs 4 disposed between the upper support and the lower support. A traveling wheel 5 is provided at the bottom of the lower support 3. There are two telescopic legs, and the two telescopic legs are arranged at intervals in the left-right direction. In this embodiment, the positioning of each telescopic leg after telescoping is achieved by two pins 20 arranged at intervals in the up-down direction. Pull out the pins, and the telescopic legs can be freely telescoped. When the height of the telescopic legs is adjusted in place, pins need to be inserted into the corresponding pin holes of the two legs in telescopic cooperation to achieve the height positioning of the telescopic legs.

[0025] The upper support includes an intermediate support cross beam whose length extends in the left-right direction. A plurality of support longitudinal beams whose lengths extend in the front-back direction are fixed on the intermediate support cross beam. The support longitudinal beams are arranged at intervals in the front-back direction. The front and rear ends of each support longitudinal beam are respectively fixed with a front support cross beam and a rear support cross beam.

[0026] Two mounting sleeves 12 arranged at intervals in the left-right direction are fixed on the intermediate support cross beam. The axis of the mounting sleeve 12 extends in the left-right direction. A rigid gas main pipe 13 whose rotation axis extends in the left-right direction is rotatably assembled in the inner hole of the mounting sleeve. A main pipe fixing structure for fixing the position of the rigid gas main pipe after rotational adjustment is provided between the device support and the rigid gas main pipe. The main pipe fixing structure includes a tightening screw 11 threadedly connected to the corresponding mounting sleeve for pressing against the rigid gas main pipe. Loosen the tightening screw, and the rigid gas main pipe can rotate. When the tightening screw is tightened, the rigid gas main pipe can rotate.

[0027] A rotary joint 16 for rotatably connecting with a gas pipe 17 is provided at the air inlet end of the rigid gas main pipe 13. Through the setting of the rotary joint 16, the gas pipe 17 cannot rotate, and the rigid gas main pipe 13 can rotate relative to the gas pipe.

[0028] The steel claw drying device further includes a plurality of nozzles 9 arranged at intervals in the left-right direction, and an ignition needle 8 is arranged beside each nozzle 9. In this embodiment, there are four nozzles 9. During use, each nozzle is placed directly below the corresponding claw part of the steel claw 14, and the nozzle sprays fire upward to dry the claw part.

[0029] The rigid gas main pipe has C-shaped pipe sections 18 corresponding to the number of nozzles. The nozzles are connected to the C-shaped pipe sections 18 through rigid gas branch pipes 10 extending radially along the rigid gas main pipe. During the rotation of the rigid gas main pipe, there are a working position that makes the C-shaped pipe section and the rigid gas branch pipe in a vertical posture and a stowed position that makes the C-shaped pipe section and the rigid gas branch pipe in a horizontal posture. Both the rigid gas main pipe and the rigid gas branch pipe are metal pipes.

[0030] In the stowed position, the concave part 19 of the C-shaped pipe section is used to avoid the graphite solution dripping from the corresponding steel claw.

[0031] On the device bracket, a front bracket and a rear bracket are arranged on the front and rear sides of the rigid gas main pipe. Wind shields are arranged at the upper ends of the front bracket and the rear bracket. Both the front bracket and the rear bracket include a plurality of bracket rods arranged at intervals in the left-right direction. During the rotation of the rigid gas branch pipe from the working position to the stowed position, the rigid gas branch pipe passes through the gap between two adjacent bracket rods. The lower ends of the bracket rods of the front bracket are fixed on the front bracket cross beam, and the lower ends of the bracket rods of the rear bracket are fixed on the rear bracket cross beam.

[0032] The bracket rod is a telescopic rod with adjustable height. After adjusting the telescopic height of the bracket rod, the height of the bracket rod is fixed by a bracket rod tightening screw.

[0033] During use, move the steel claw drying device to the lower side of the steel claw to be dried. If the graphite solution on the steel claw can still flow and drip, first rotate the rigid gas main pipe to the stowed position. At this time, the dripping graphite solution just passes through the concave part of the C-shaped pipe section and will not adhere to the nozzles and ignition needles. When the graphite solution on the steel claw can no longer flow and drip, rotate the rigid gas main pipe to the working position. At this time, the nozzles can spray fire upward to dry the claw part of the steel claw. Adjust the telescopic legs to adjust the height of the nozzles relative to the steel claw and improve the fire spraying effect; adjust the height of the bracket rods to adjust the height of the wind shields, which helps to ensure that the heat at the drying position does not escape and guarantees the drying effect.

[0034] In the above description of this specification, unless otherwise clearly defined and limited, terms such as "fixed", "installed", "connected" or "coupled" should be understood in a broad sense. For example, for the term "connected", it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, or it can be the communication inside two components or the interaction relationship between two components. Therefore, unless otherwise clearly defined in this specification, those skilled in the art can understand the specific meanings of the above terms in this utility model according to specific circumstances.

[0035] According to the above description of this specification, those skilled in the art can also understand the terms used as follows. For example, terms indicating orientation or positional relationships such as "upper", "lower", "front", "rear", "left", "right", "length", "width", "thickness", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", "center", "longitudinal", "transverse", "clockwise" or "counterclockwise" are based on the orientation or positional relationships shown in the drawings of this specification. They are only for the purpose of facilitating the description of the solution of this utility model and simplifying the description, rather than explicitly or implicitly indicating that the devices or components involved must have the specific orientation, be constructed and operated in the specific orientation. Therefore, the above terms of orientation or positional relationships cannot be understood or interpreted as limitations on the solution of this utility model.
