Description

Technical Field

[0001] This invention relates to the field of smelting furnace technology, and more specifically to an online temperature monitoring device for the reaction tower of a copper smelting flash smelting furnace. Background Technology

[0002] In modern metallurgy and non-ferrous metal refining, blowing furnaces are widely used as highly efficient and energy-saving production equipment. These blowing furnaces are typically equipped with a copper water jacket cooling system, the core function of which is to absorb the large amount of heat generated inside the furnace through circulating cooling water, thereby maintaining the stability and safe operation of the furnace structure.

[0003] The reaction process in a flash furnace mainly takes place in the reaction tower. If the material and oxygen-enriched air are not mixed evenly inside the reaction tower, the degree of reaction will be greatly affected. In severe cases, raw material may accumulate at the bottom of the reaction tower. Therefore, a means is needed to reflect the reaction status of the material inside the reaction tower to avoid material segregation. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide an online temperature monitoring device for the reaction tower of a copper smelting flash smelting furnace.

[0008] A mounting bracket is provided on the cylinder, and the mounting bracket has a mounting groove for inserting thermocouples;

[0009] A positioning component, located within the mounting bracket, is used to secure the thermocouple.

[0030] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0031] Reference Figures 1-6 As shown, an online temperature monitoring device for the reaction tower of a copper smelting flash smelting furnace includes a reaction tower body composed of a multi-layered cylindrical body 1 and a copper water jacket 2. A nozzle 3 is installed at the top of the reaction tower body. The composition of the reactant material in the reaction tower body is Cu: 55-72%, Fe: 5-10%, S: 20-25%, CaO: 3.5-4.5%, H2O≤0.2%; the particle size of the material is 0-5mm, and the reaction temperature in the tower is ≤1450℃.

[0032] The shell of the reaction tower is columnar, with a height of 7.9m and a diameter of 7m. The tower body is axially separated by 21 layers of copper water jacket 2 and 20 layers of cylindrical body 1. The thickness of the refractory bricks inside the cylindrical body 1 is 250mm.

[0033] Temperature monitoring points are installed at point 1 on layers 2, 4, 6, 8, 10, 12, 15, and 17 of the cylindrical body, and a temperature monitoring point is installed every 45°.

[0034] All the temperature data above are uploaded to the DCS system and collected by the intelligent scheduling and optimization system of the process internet platform. The system can monitor the temperature and trend inside the flash smelting furnace reaction tower in real time, and the intelligent scheduling and optimization system can provide feedback and suggestions for adjusting operating parameters based on the current production parameters.

[0035] Also includes:

[0036] Thermocouple 5 is installed at the temperature monitoring point to measure the reaction temperature inside the reaction tower;

[0037] Mounting bracket 4 is set on cylinder 1. Mounting bracket 4 has a mounting groove 40 for inserting thermocouple 5.

[0038] The positioning component 41 is set inside the mounting bracket 4. Cavities are provided on both sides of the mounting groove 40, and the positioning component 41 is set inside the cavity. An openable cover plate is also provided on the top of the cavity for fixing the thermocouple 5.

[0039] A self-locking mechanism is provided on one side of the positioning component 41 and is used to lock the positioning component 41.

[0040] When installing thermocouple 5, insert thermocouple 5 into the mounting slot 40, and the positioning component 41 will fix thermocouple 5 in place. The positioning component 41 will then activate the self-locking mechanism to lock the positioning component 41.

[0041] In one embodiment, the positioning component 41 includes a movable plate 411. The middle part of the movable plate 411 is rotatably connected to the inner wall of the cavity of the mounting bracket 4 via a fixed pivot 412. A first insert plate 414 is provided on the movable plate 411. A first slot is provided on the side of the cavity near the mounting groove 40. The first insert plate 414 can be inserted into the mounting groove 40 through the first slot. The thermocouple 5 is provided with a positioning hole 51 that mates with the first insert plate 414. When the thermocouple 5 is fully inserted, the first insert plate 414 can be inserted into the positioning hole 51 to clamp and fix the thermocouple 5. One end of the first insert plate 414 is... A first movable slider 413 is rotatably connected to the movable plate 411. A second insert plate 416 is provided at the bottom of the first insert plate 414. A second slot is provided on the side of the cavity near the mounting groove 40. Initially, the second insert plate 416 is inserted into the mounting groove 40 through the second slot. The second insert plate 416 is retractable. A second movable slider 415 is rotatably connected to the movable plate 411. A third movable slider 417 is rotatably connected to the self-locking mechanism on the side of the movable plate 411 away from the first insert plate 414.

[0042] In one embodiment, the second insert plate 416 includes a fixed sleeve 4161 rotatably connected to the second movable slider 415. A telescopic plug 4162 is provided inside the fixed sleeve 4161. One end of the telescopic plug 4162 and a telescopic mechanism are also provided inside the fixed sleeve 4161. The telescopic plug 4162 is slidably connected to the fixed sleeve 4161 through the telescopic mechanism.

[0043] After the thermocouple 5 is inserted along the mounting groove 40, the thermocouple 5 will first push the second insert plate 416 outward. Since the first insert plate 414 is blocked by the thermocouple 5, the telescopic plug 4162 retracts into the fixed sleeve 4161 and compresses the telescopic mechanism. When the thermocouple 5 is fully inserted into the mounting groove 40, when the first insert plate 414 is aligned with the positioning hole 51, the movable plate 411 will deflect along the fixed rotating shaft 412 under the elastic force of the telescopic mechanism, so that the first insert plate 414 is inserted into the positioning hole 51, thus completing the fixation of the thermocouple 5. At the same time, when the movable plate 411 deflects, it will also activate the self-locking mechanism.

[0044] In one embodiment, the side wall of the fixed sleeve 4161 is provided with a movable groove, and the telescopic mechanism includes a guide rod 4163 located in the movable groove. One end of the telescopic plug 4162 is provided with a limiting slider 4164 sleeved on the guide rod 4163, and one side of the limiting slider 4164 is provided with a return spring 4165 sleeved on the guide rod 4163. When the telescopic plug 4162 is initially compressed, the telescopic plug 4162 will drive the limiting slider 4164 to slide on the guide rod 4163, and the limiting slider 4164 will compress the return spring 4165.

[0045] In one embodiment, the self-locking mechanism includes a driven component 42 that is rotatably connected to the third movable slider 417. The top of the driven component 42 is provided with a locking component 43 that is slidably connected to the mounting bracket 4, and the locking component 43 is engaged with the driven component 42.

[0046] When the movable plate 411 rotates, it pulls the driven component 42 to move. The locking component 43 has a built-in anti-reverse mechanism, which ensures that the driven component 42 can only move forward and prevents it from moving backward.

[0047] In one embodiment, the driven component 42 includes a driven plate 421, with sliding plates 424 slidably connected to the mounting bracket 4 on both sides of the driven plate 421, and a connecting block 425 rotatably connected to the third moving slider 417 at one end of the driven plate 421. A buckle is also provided inside the driven plate 421 to engage with the locking component 43.

[0048] The locking assembly 43 includes a locking plate 431, which has multiple locking grooves that cooperate with the buckle. A slide rod 433 is provided inside the mounting bracket 4. Lifting sliders 432 are provided on both sides of the locking plate 431 and are fitted onto the slide rods 433. A locking spring 434 is provided on one side of the lifting slider 432 and is fitted onto the slide rods 433. A handle 435 is fixedly provided on the top of the locking plate 431.

[0049] A limiting groove is provided on the driven plate 421. The fastener includes multiple identical positioning rods 422 located in the limiting groove. The positioning rods 422 are inserted into the locking groove. The positioning rods 422 and the locking groove are both inclined on one side near the connecting block 425, and both on the other side are vertical. This is mainly to facilitate the positioning rods 422 to slide along the inclined surface, while the vertical surface can prevent them from sliding backward. A positioning spring 423 is provided at one end of the positioning rod 422 and in the limiting groove. The positioning rod 422 is connected to the bottom of the limiting groove through the positioning spring 423.

[0050] When the movable plate 411 pulls the driven plate 421, the driven plate 421 moves forward, which in turn pulls the positioning rod 422 to move together. The positioning rod 422 is squeezed and retracts inward. When it moves to the next locking groove, the positioning rod 422 will be inserted into it to complete the fixation. In the later disassembly, you only need to pull the handle 435 upward to make the locking plate 431 disengage from the driven plate 421. At this time, the driven plate 421 is also released from the restriction and can be pulled backward to open it, allowing the thermocouple 5 to be pulled out.

[0051] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
