Description

Technical Field

[0001] This utility model belongs to the field of auxiliary equipment for smelting furnaces, and in particular relates to a tuyer device for a copper smelting furnace. Background Technology

[0002] A vent, also known as an air inlet, is a gas inlet in a copper smelting furnace used to introduce air or oxygen-enriched gas into the furnace to maintain the high-temperature reaction inside. "Blocking the vent" refers to the operational procedure of temporarily sealing the vent with a drill rod during the operation of a copper smelting furnace to limit the amount of gas entering and thus control the process effects within the furnace.

[0003] In existing technologies, the operation of plugging vents is mainly carried out manually. Due to the high temperatures near the copper smelting furnace, workers must wear heavy heat-insulating gear, resulting in low efficiency and certain safety risks. Furthermore, when plugging vents manually, the insertion effectiveness of the drill rod inside the vent depends entirely on the operator's experience, making the sealing effect unpredictable. This can easily lead to the copper smelting furnace failing to achieve the desired process results, resulting in unnecessary economic losses. Utility Model Content

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] A tuyer device for a copper smelting furnace, the structure of which can be made of Figures 1-4 The diagram is shown below. In this embodiment, the tuyer device for the copper smelting furnace includes: a support frame 1, a drill rod 2, a drive cylinder 3, and a connecting frame 4.

[0027] Specifically, the bottom surface of the support frame 1 is provided with a first connecting lug 11 and a guide rail 12, and a slidable connecting seat 7 is provided on the guide rail 12. The drill rod 2 is detachably mounted on the connecting seat 7, and the length direction of the drill rod 2 is parallel to the length direction of the guide rail 12. The drive cylinder 3 is detachably mounted on the bottom surface of the support frame 1, and the drive cylinder 3 and the first connecting lug 11 are respectively located at both ends of the guide rail 12, and the telescopic rod of the drive cylinder 3 is detachably connected to the connecting seat 7. The connecting frame 4 is detachably mounted on the gas pipe 9 of the copper smelting furnace, and a second connecting lug 41 hinged to the first connecting lug 11 is provided on the top of the connecting frame 4.

[0028] During the venting operation, the extension rod of the drive cylinder 3 will extend, causing the connecting seat 7 to slide towards the connecting frame 4. At this time, the drill rod 2 will insert into the vent (i.e., the opening of the gas pipe 9) along the connecting frame 4, thus sealing the vent and limiting the amount of gas entering, ensuring the process effect inside the copper smelting furnace meets actual requirements. Furthermore, the operator can adjust the extension stroke of the drive cylinder 3 according to actual conditions to ensure the drill rod 2's insertion into the vent meets specific needs. After the process inside the copper smelting furnace is completed, the extension rod of the drive cylinder 3 can be shortened. At this time, the connecting seat 7 will slide towards the drive cylinder 3, causing the drill rod 2 to exit the vent (i.e., the opening of the gas pipe 9), thus restoring normal gas supply.

[0029] Optionally, to achieve a detachable connection between the telescopic rod of the drive cylinder 3 and the connecting seat 7, a connecting screw head 31 can be provided at the end of the telescopic rod of the drive cylinder 3, and the outer diameter of the connecting screw head 31 should be smaller than the outer diameter of the telescopic rod of the drive cylinder 3. Correspondingly, a connecting plate 72 should be provided on the connecting seat 7, and a connecting hole should be provided on the connecting plate 72. At the same time, a locking nut 32 should also be provided on the connecting screw head 31, and the locking nut 32 and the telescopic rod of the drive cylinder 3 are respectively located on both sides of the connecting plate 72. During assembly, the operator can insert the connecting screw head 31 into the connecting hole and use the locking nut 32 to prevent the connecting screw head 31 from separating from the connecting plate 72, thereby allowing the connecting seat 7 to move with the extension or retraction of the telescopic rod of the drive cylinder 3.

[0030] In addition, to achieve a detachable connection between the drill rod 2 and the connecting seat 7, a connecting plate 21 is provided on the drill rod 2. During assembly, the operator installs the connecting plate 21 onto the side wall of the connecting seat 7 near the connecting frame 4 using bolts or other common detachable connection methods to ensure that the drill rod 2 follows the movement of the connecting seat 7.

[0031] As an optional implementation of this embodiment, in order to improve the stability of the drill rod 2 on the connecting seat 7, the connecting seat 7 may also be provided with a receiving hook 71 for accommodating the drill rod 2, thereby supporting the drill rod 2 by means of the receiving hook 71.

[0032] Figure 4 The diagram shows the structure of the connecting frame 4. The connecting frame 4 may include a guide tube 42 and a tube bracket 43 for supporting the air guide tube 9. The axis of the tube bracket 43 is aligned with the axis of the guide tube 42, and the guide tube 42 is located on the side of the tube bracket 43 closest to the guide rail 12. During assembly between the connecting frame 4 and the air guide tube 9, the worker can place the air guide tube 9 inside the tube bracket 43 and fix it to the tube bracket 43 using pipe clamps or other common pipe fittings. Because the axis of the tube bracket 43 is aligned with the axis of the guide tube 42, after the air guide tube 9 is placed inside the tube bracket 43, the axis of the air guide tube 9 will be aligned with the axis of the guide tube 42. During the air hole insertion operation, the guide tube 42 guides the drill rod 2, allowing it to be smoothly inserted into the air hole (i.e., the opening of the air guide tube 9).

[0033] To prevent the device from obstructing the area near the air duct 9 when the venting operation is not required, this embodiment may further include a top beam 5 and a lifting cylinder 6. The top beam 5 is positioned above the support frame 1, and a third connecting lug 51 is located at the bottom of the top beam 5. A fourth connecting lug 13 is also provided on the top surface of the support frame 1, and the fourth connecting lug 13 is located between the first connecting lug 11 and the drive cylinder 3. The lifting cylinder 6 is positioned between the top beam 5 and the support frame 1, and the lifting cylinder 6 is hinged to the third connecting lug 51, with its extension rod hinged to the fourth connecting lug 13.

[0034] like Figure 1 and Figure 2 As shown, when the telescopic rod of the lifting cylinder 6 is extended to its limit, the axis of the chisel 2 will be aligned with the axis of the air guide pipe 9. At this time, the action of the driving cylinder 3 can drive the chisel 2 to insert or withdraw from the air hole (i.e., the opening of the air guide pipe 9).

[0035] When there is no need to operate the air vent, the telescopic rod of the lifting cylinder 6 can be driven to shorten. At this time, the support frame 1 will flip upward around the hinge point of the first connecting ear 11 and the second connecting ear 41, thereby avoiding obstruction of the air inlet area of ​​the air duct 9 and ensuring that the staff has more operating space.

[0036] As another optional implementation of this embodiment, to further improve the movement accuracy of the drill rod 2, the device may also include a guide seat 8. Specifically, the guide seat 8 is detachably mounted on the guide slide rail 12, and a guide hook 81 for accommodating the drill rod 2 is provided on the guide seat 8, and the guide seat 8 should be located between the connecting seat 7 and the connecting frame 4. In use, the guide hook 81 can support the drill rod 2 between the connecting frame 4 and the connecting seat 7, thereby preventing the drill rod 2 from bending due to its excessive length, and ensuring that the drill rod 2 is accurately inserted into the air hole (i.e., the opening of the air duct 9).

[0037] It should be noted that the staff should set the specific installation position of the guide seat 8 according to the actual travel of the connecting seat 7, so as to avoid the guide seat 8 from causing undue influence on the normal operation of the connecting seat 7.

[0038] The effects of the above solution are explained below:

[0039] This embodiment provides a tuyer device for a copper smelting furnace. It automatically completes the tuyer operation by driving a connecting seat to slide using a drive cylinder, improving operational efficiency and reducing worker safety. Secondly, the device can flexibly control the stroke of the drive cylinder according to actual needs, ensuring good insertion of the drill rod. Furthermore, the device can also tilt the support frame upwards using a lifting cylinder to prevent undue obstruction of the air duct area when the tuyer is not needed.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
