[0002] Metal smelting is the process of melting solid metal into liquid in a heating furnace and tempering it. It is one of the casting production processes. During smelting, the furnace charge undergoes certain physical and chemical changes in the high-temperature furnace, producing crude metal or metal concentrates and slag. This process is particularly important in pyrometallurgy. In addition to concentrates, roasted sand, sinter, etc., the furnace charge sometimes needs to be mixed with flux to make it easier to melt, as well as reducing agents added to carry out certain reactions. Smelting technology has a long history. As early as the Shang Dynasty in China, there were mature crucible manufacturing processes and systems used for metal smelting.

[0003] Please refer to the high-temperature molten metal temperature measuring device published in Announcement No. CN208458891 U.

It solves the problem that the comparative patent is inconvenient to quickly elongate and adjust the temperature measuring coupler during use and cannot effectively contact the metal smelting material.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a metal smelting temperature measuring device, comprising a mounting cylinder, wherein an adjusting elongation mechanism is provided inside the mounting cylinder;

[0006] The adjusting elongation mechanism includes a rotary motor fixedly installed inside the mounting cylinder, a reciprocating lead screw rotatably connected to the mounting cylinder on the output shaft of the rotary motor, a threaded block threadedly connected to the outer side of the reciprocating lead screw, a limiting plate slidably connected to the mounting cylinder fixedly installed at the top and bottom of the threaded block, and a hand-held bracket fixedly installed on the outer side of the mounting cylinder.

[0007] A support rod is fixedly installed on one side of the limiting plate, and a mounting base is fixedly installed on the right side of the support rod. An adjusting cylinder is movably connected to the outside of the mounting base, and a temperature measuring thermocouple is provided on the inside of the adjusting cylinder.

[0013] Furthermore, the pull ring has two circular slots inside, and the pull ring is used to pull the pull rope.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] This metal smelting temperature measuring device, through its adjustable extension mechanism, uses a rotary motor and a reciprocating screw to move a threaded block to the right, thereby moving a support rod, mounting base, adjusting cylinder, and thermocouple. This allows the thermocouple to extend, facilitating its insertion into the molten metal for temperature measurement.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 The metal smelting temperature measuring device in this embodiment includes a mounting cylinder 1, and an adjustment elongation mechanism is provided inside the mounting cylinder 1.

[0023] In the first embodiment, the elongation adjustment mechanism includes a rotary motor 2 fixedly installed inside the mounting cylinder 1. The output shaft of the rotary motor 2 is fixedly installed with a reciprocating screw 3 that is rotatably connected to the mounting cylinder 1. A threaded block 4 is threadedly connected to the outer side of the reciprocating screw 3. A threaded groove is opened inside the threaded block 4. The threaded block 4 is threadedly connected to the reciprocating screw 3 through the threaded groove, which helps the threaded block 4 to move on the outer side of the reciprocating screw 3.

[0024] Among them, the top and bottom of the threaded block 4 are fixedly installed with limiting plates 5 that are slidably connected to the mounting cylinder 1. The top and bottom of the mounting cylinder 1 are provided with limiting grooves. The limiting plates 5 are movably connected to the mounting cylinder 1 through the limiting grooves, which helps the limiting plates 5 to move inside the mounting cylinder 1. A hand-held bracket 6 is fixedly installed on the outside of the mounting cylinder 1.

[0025] In this embodiment, a support rod 7 is fixedly installed on one side of the limiting plate 5, and a mounting base 8 is fixedly installed on the right side of the support rod 7. An adjusting cylinder 9 is movably connected to the outside of the mounting base 8, a temperature measuring thermocouple 10 is provided on the inside of the adjusting cylinder 9, and an angle adjustment component is provided on one side of the mounting base 8.

[0026] In embodiment 2, the angle adjustment assembly includes a telescopic spring 11 hinged to the right side of the mounting base 8, a fixed plate 12 fixedly mounted on one side of the telescopic spring 11, a movable rod 13 hinged to the inside of the fixed plate 12 and hinged to the adjusting cylinder 9, and a pull rope 14 movably connected to the left side of the fixed plate 12. The angle adjustment assembly also includes a limiting seat 15 movably connected to the outside of the pull rope 14 and fixedly connected to the mounting base 8.

[0027] The limiting seat 15 has a movable groove inside, and the pull rope 14 is movably connected to the limiting seat 15 through the movable groove, which helps the limiting seat 15 to limit the pull rope 14. A pull ring 16 is fixedly installed on the other side of the pull rope 14. The pull ring 16 has two circular through grooves inside, and the pull ring 16 is used to pull the pull rope 14, which helps to move the pull ring 16.

[0028] It should be noted that this metal smelting temperature measuring device, through the set adjustment extension mechanism, uses the rotary motor 2 and the reciprocating screw 3 to drive the threaded block 4 to move to the right, thereby moving the support rod 7, mounting base 8, adjusting cylinder 9 and temperature measuring coupler 10, so that the temperature measuring coupler 10 can be extended to facilitate its movement into the metal smelting material for temperature measurement. Pulling the pull ring 16 can move the pull rope 14, and at the same time, it can compress the telescopic spring 11 and pull the movable rod 13 to move. The movement of the movable rod 13 causes the outer side of the mounting base 8 to rotate. The rotation of the adjusting cylinder 9 can cause the temperature measuring coupler 10 to rise or fall, making it easier to insert into the interior of the metal smelting material, which helps to measure the temperature more effectively and increases the flexibility of the device.

[0029] The working principle of the above embodiments is as follows:

[0030] When using this metal smelting temperature measuring device, the handheld frame 6 can be moved first, and the mounting cylinder 1, adjusting cylinder 9 and temperature measuring coupler 10 can be moved through the handheld frame 6 until the temperature measuring coupler 10 moves to the top of the metal smelting furnace. Then, the rotary motor 2 can be started to drive the reciprocating screw 3 to rotate. The threaded block 4 on the outside of the reciprocating screw 3 moves left and right under the limit of the limiting plate 5. The movement of the threaded block 4 to the right drives the support rod 7, mounting base 8, adjusting cylinder 9 and temperature measuring coupler 10 to move, so that the temperature measuring coupler 10 can be extended and moved into the metal smelting furnace for temperature measurement.

[0031] Pulling the pull ring 16 can also move the pull rope 14, which in turn moves the fixed plate 12. As the fixed plate 12 moves, it can compress the telescopic spring 11 and pull the movable rod 13. The movement of the movable rod 13 causes the outer side of the mounting base 8 to rotate. The rotation of the adjusting cylinder 9 can cause the temperature measuring coupler 10 to rise or fall, making it easier to insert into the interior of the molten metal material. This helps to measure the temperature more effectively and greatly improves the flexibility and practicality of the device.
