Description

Technical Field

[0001] The utility model relates to the technical field of copper smelting, in particular to an emergency drive device for a converter. Background Art

[0002] The converter in copper smelting is an important equipment for refining the matte produced by the flash furnace into crude copper required for the anode furnace. The shaking furnace system is the throat equipment of the converter. If the shaking furnace system fails during the normal air supply production process of the converter, the furnace body cannot be shaken to a safe angle in time, which may cause the blower to surge and excessive copper blowing reaction at the least, and may cause major production accidents such as damage to the blower and blocked air eye at the worst. For some converters that are not equipped with a second drive system, and due to the small on-site space and limited renovation funds, how to provide a set of emergency drive devices under various restrictions has become a problem to be solved.

[0016] The embodiment of the present application provides an emergency drive device for a converter, which effectively solves the problem that if a furnace shaking system fails during the normal air supply production process of the converter, the furnace body cannot be shaken to a safe angle in time, which may cause the blower to surge and excessive copper blowing reaction at the least, or cause serious production accidents such as damage to the blower and blocked air eye at the worst. Under the limitations of on-site space and renovation funds, a small reducer is added to the tail of the existing drive motor to transmit the driving force through the mechanical structure to meet the need for emergency furnace shaking.

[0017] Example

[0018] like Figure 1As shown, the technical solution in the embodiment of the present application is to effectively solve the technical problem that if the shaking furnace system fails during the normal air supply production process of the converter, the furnace body cannot be shaken to a safe angle in time, which may cause the blower to surge and excessive copper blowing reaction at the least, and may cause damage to the blower, block the air eye and other major production accidents at the worst. The overall idea is as follows: a converter emergency drive device, including a reducer body 1, a drive spindle 2, a first mounting key 3, a backrest wheel 4, a motor extension shaft 5, a second mounting key 6, a key pin 7 and a furnace body motor 8. The rotor of the furnace body motor 8 is provided with a center hole required for the installation of the motor extension shaft 5. The motor extension shaft 5 is fixed in the center hole of the furnace body motor 8 by the key pin 7. The backrest wheel 4 includes two, one of which is mounted on the motor extension shaft 5 by the second mounting key 6. On, another backrest wheel 4 is installed on the driving main shaft 2 through the first installation key 3, the backrest wheel 4 and the motor extension shaft 5 are interference fit, the backrest wheel 4 and the driving main shaft 2 are clearance fit, the driving main shaft 2 is installed on the reducer body 1 through the first installation key 3, when the emergency drive device is needed, the two backrest wheels 4 are engaged by pushing the backrest wheel 4, and then the reducer body 1 is started, the reducer body 1 rotates to drive the driving main shaft 2 to rotate, the driving main shaft 2 rotates to drive the backrest wheel 4 to rotate, the backrest wheel 4 rotates to drive the motor extension shaft 5 to rotate, the motor extension shaft 5 rotates to drive the furnace body motor 8 to rotate, and finally the furnace body motor 8 transmits the drive to drive the converter body to shake the furnace. The emergency drive device can not only be used for converter shaking, but also can be used for most equipment systems that only have a single drive device and urgently need a backup drive device.

[0019] In view of the problems existing in the prior art, the utility model provides a converter emergency drive device. Under the limitation of on-site space and transformation funds, a small reducer is added to the tail of the existing drive motor to transmit the driving force through the mechanical structure to meet the demand of emergency shaking of the furnace.

[0020] Working principle:

[0021] The first step is to use the emergency drive device by pushing the backrest wheels 4 to engage the two backrest wheels 4, and then start the reducer body 1. The reducer body 1 rotates to drive the driving main shaft 2, and the driving main shaft 2 rotates to drive the backrest wheels 4. The rotation of the backrest wheels 4 drives the motor extension shaft 5 to rotate, and the rotation of the motor extension shaft 5 drives the furnace body motor 8 to rotate, and finally the furnace body motor 8 transmits the drive to drive the converter body to shake the furnace.

[0022] In the second step, the emergency drive device can not only be used for converter shaking, but also for most equipment systems that only have a single drive device and urgently need a backup drive device.

[0023] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
