[0002] When metal is melted in a metal smelting furnace, a thermocouple needs to be arranged inside the furnace to monitor the temperature inside the furnace, so as to ensure the smelting efficiency and quality of the metal. However, the thermocouples inside the existing metal smelting furnace are not always monitoring the operation, which requires the existing metal smelting furnace to be provided with a storage tube inside to protect the thermocouples. However, most of the existing thermocouples are arranged on the furnace cover of the metal smelting furnace, and no sealing structure for protecting the storage tube is arranged on the lower side. As a result, when the molten metal inside the metal smelting furnace splashes, it will still come into contact with the thermocouple inside the storage tube, which obviously poses a great safety hazard. For this reason, we propose a metal smelting furnace that is convenient for furnace temperature monitoring. Utility Model Content

[0029] Specifically, through the sliding cooperation between each sealing block 23 and the sealing plate 20 and the driving plate 21, and through the sliding cooperation between the driving slider 33 and the driving slide groove 32, when the thermocouple body 2 is unfolded downward, it can drive each sealing block 23 to expand outward, so as to facilitate the thermocouple body 2 to extend downward, and when the thermocouple body 2 is contracted upward, it can drive each sealing block 23 to contract inward, so as to seal the lower end of the storage tube 11, thereby achieving the effect of protecting the thermocouple body 2 inside it, and then through the sliding cooperation between the driving slider 33 and the driving slide groove 32, the sealing block 23 can be positioned to prevent it from loosening.
[0030] In another embodiment provided by the present invention, the inner side of the upper end surface of each sealing block 23 is inclined, and the upper and lower end surfaces of each sealing block 23 are respectively fixedly installed with a sliding shaft 24 and a limiting slider 26, the upper end surface of the sealing plate 20 is provided with a plurality of limiting grooves 27 that are respectively slidably matched with each limiting slider 26, and the lower end surface of the driving plate 21 is provided with a plurality of inclined grooves 25 that are respectively slidably matched with each sliding shaft 24.
[0031] Specifically, through the sliding cooperation between the limiting slider 26 and the limiting slot 27, the movement direction of each sealing block 23 can be limited on the upper end surface of the sealing plate 20, so that the rotating driving plate 21 can drive each sealing block 23 to shrink inward or expand outward through the sliding cooperation between the inclined slot 25 and the sliding shaft 24.
[0032] In another embodiment provided by the present invention, a partition plate 41 is fixedly installed on the upper side of the inner cavity of the storage tube 11, a limiting insertion cavity 42 is provided on the lower end surface of the partition plate 41, a threaded sleeve 43 which is plugged into the inner cavity of the limiting insertion cavity 42 is fixedly installed on the upper end surface of the movable plate 31, a threaded rod 44 which is threadably matched with the threaded sleeve 43 is rotatably installed in the limiting insertion cavity 42, a motor 4 is fixedly installed on the upper end surface of the partition plate 41, and the lower end surface of the motor 4 is fixedly connected to the middle part of the upper end of the threaded rod 44 through its output shaft.
[0033] Specifically, the movement direction of the threaded sleeve 43 can be limited by the plug-in cooperation between the threaded sleeve 43 and the limiting insertion cavity 42, so that when the motor 4 drives the threaded rod 44 to rotate through its output shaft, it can drive the threaded sleeve 43 and the thermocouple body 2 at the lower end of the threaded sleeve 43 to move up and down.
[0034] In another embodiment provided by the present invention, a wire 5 and a wire organizer 51 are provided in the storage tube 11, the wire 5 is fixed between the thermocouple body 2 and the storage tube 11, and limit blocks 53 symmetrically arranged on the left and right are fixedly installed on the upper and lower sides of the inner cavity of the wire organizer 51, and the wire 5 is inserted between the limit blocks 53 on the left and right sides. A wire take-up block 52 is rotatably installed in the wire organizer 51, and the middle part of the wire take-up block 52 is fixedly connected to the wire 5, and limited rotation cavities 50 are respectively provided on both sides of the wire organizer 51, and annular rotating seats 55 rotatably connected to the limited rotation cavities 50 on both sides are fixedly installed on both sides of the outer periphery of the wire take-up block 52, a socket 56 is provided in the middle part of the annular rotating seat 55, and a spring 54 inserted into the socket 56 is provided on the outer periphery of the annular rotating seat 55, and the outer end of the spring 54 is clamped with the inner wall of the limited rotation cavity 50.
[0035] Specifically, when the thermocouple body 2 contracts upward or expands downward, the spring 54 between the annular rotating seat 55 and the limiting rotating cavity 50 is cooperated so that the moving thermocouple body 2 can drive the wire 5 to be rolled up or released outside the wire organizer 51, thereby achieving the effect of arranging the wire 5 and avoiding contact between the middle part of the wire 5 and the thermocouple body 2, thereby protecting both.
[0036] Working principle: When storing the thermocouple body 2, start the motor 4, and drive the threaded rod 44 to rotate through its output shaft. The limiting plug cavity 42 is plugged in with the threaded sleeve 43 to limit the movement direction of the threaded sleeve 43, so that the rotating threaded rod 44 can drive the threaded sleeve 43 and the thermocouple body 2 at the lower end of the threaded sleeve 43 to move upward through the threaded cooperation between it and the threaded sleeve 43, and store it in the storage cylinder 11. When the driving slider 33 on the periphery of the movable plate 31 contacts the inclined section in the middle of the driving groove 32 on the inner wall of the rotating cylinder 3, the rotating cylinder 3 can be driven to rotate on the inner wall of the storage cylinder 11, so that the rotating cylinder 3 can be To drive the driving plate 21 to rotate on the upper end of the sealing plate 20, the sealing plate 20 restricts the movement direction of each sealing block 23 through the sliding cooperation between the limiting slide groove 27 and the limiting slider 26, so that the rotating driving plate 21 can drive each sealing block 23 to retract inward through the sliding cooperation between the sliding shaft 24 and the inclined slide groove 25, so as to seal the lower end of the storage tube 11, and when the driving slider 33 contacts the upper section of the driving slide groove 32, the driving plate 21 can be positioned in the storage tube 11, so that the sealing block 23 can be positioned to avoid loosening of the sealing block 23 and ensure the sealing effect of the sealing block 23 on the lower end of the storage tube 11.
[0037] On the contrary, starting the output shaft of the motor 4 to rotate in the reverse direction can drive the sealing block 23 to expand outward, and drive the thermocouple body 2 to expand downward, so that the thermocouple body 2 can monitor the internal temperature of the metal smelting furnace.
[0038] When the thermocouple body 2 is in motion, the moving thermocouple body 2 can drive the wire 5 to move with it. When the wire 5 extends downward with the thermocouple body 2, the wire 5 can drive the wire take-up block 52 fixedly connected thereto to rotate in the wire organizer 51, so that the wire 5 outside the wire take-up block 52 can be released, thereby achieving the effect of expanding the wire 5, and during the rotation of the wire take-up block 52, the middle part of the spring 54 can be driven to rotate, and the outer end of the spring 54 is engaged with the inner wall of the limiting rotation cavity 50, so that the spring 54 is deformed. This makes the relaxed wire 5 lose the limiting effect on the spring 54 when the thermocouple body 2 contracts upward. Under the action of the spring 54 restoring its deformation, the wire take-up block 52 can be driven to rotate in the opposite direction, and then the wire 5 can be rolled up around the wire take-up block 52, thereby achieving the effect of arranging the wire 5 and avoiding the middle part of the wire 5 from contacting the thermocouple body 2, thereby achieving the effect of protecting both.
