Description

Technical Field

[0001] This invention relates to the field of copper smelting furnace technology, specifically to a copper smelting furnace equipped with an online detection device. Background Technology

[0002] Copper smelting refers to the production activities of refining copper from raw materials such as copper concentrate and scrap copper through smelting, refining, and electrolysis. Pyrometallurgical smelting, primarily using copper sulfide concentrate, involves smelting, blowing, pyrometallurgical refining, and electrolytic refining to produce electrolytic copper. This method has the advantages of strong adaptability, fast smelting speed, full utilization of sulfur in sulfide ores, low energy consumption, and high production efficiency, making it particularly suitable for processing copper sulfide ores and oxide-rich ores. During the smelting process, various tests are required to ensure product quality and improve production efficiency. Temperature is often measured using thermocouples or infrared thermometers. Infrared thermometers use non-contact detection, resulting in larger temperature errors. Thermocouples are exposed to high temperatures for extended periods, which can damage internal components. Furthermore, impurities easily remain on the surface after temperature measurement, making cleaning difficult. These impurities can fall into the molten steel during subsequent measurements, causing contamination. Summary of the Invention

[0006] Preferably, the arc-shaped body has a through groove for the thermocouple to extend out, and the protective box is detachably connected to a connecting shell by bolts. Both the protective box and the connecting shell are fixedly installed with snap-fit ​​plates for limiting the position of the thermocouple.

[0007] Preferably, the blower assembly includes a vertical push rod fixedly installed inside the mounting box and a fixed connecting plate fixedly installed on the protective box via a connecting bracket.

The gear is rotatably connected to the middle of the fixed connecting plate. The two rack plates are located on both sides of one end of the fixed connecting plate.

[0008] Preferably, each of the two rack plates has a connecting plate fixedly connected to its far-away ends. A vertical guide rod is fixedly connected to the upper end of the upper connecting plate, which is located directly below the vertical push rod. A limiting rod is slidably inserted into each of the two rack plates. The end of the limiting rod away from the rack plate is fixedly connected to the fixed connecting plate via a connecting block. A return spring is sleeved on the limiting rod. A piston rod is fixedly connected to the close-away ends of the two connecting plates.

[0009] Preferably, each of the two piston rods is slidably connected to a fixed cavity column, and a piston plate is fixedly connected to one end of each of the two piston rods that extends into the fixed cavity column. The piston plate is slidably connected to the fixed cavity column, and the two fixed cavity columns are fixedly connected to the protective box through a fixed sleeve plate. An air outlet pipe is provided at the ends of the two fixed cavity columns that are far apart from each other.

[0010] Preferably, the cleaning assembly includes push rods symmetrically installed on both sides of the inner wall of the mounting box, a second annular tube sleeved on the protective box, and a first annular tube sleeved on the thermocouple.

[0014] Compared with the prior art, the beneficial effects of the present invention are: With a feeding port, cold air enters the connecting conduit and then the protective box. At the same time, the cold air flows out from the air outlet on the protective box, which can cool the components around the protective box and the thermocouple part inside the protective box, thereby improving the service life of the thermocouple.

[0015] As the protective box moves upward, a blowing assembly, through the cooperation of two rack plates and gears, enables two piston rods to drive two piston plates, pushing the gas in the two fixed chamber columns into the second annular tube and the first annular tube respectively. A cleaning assembly ensures that as the protective box moves upward, the second annular tube moves downward on the protective box, and the first annular tube moves downward on the thermocouple. With the cooperation of the blowing assembly and the protective box, the second and first nozzles spray air onto the protective box and the thermocouple as they move downward, cooling the surfaces of the protective box and the thermocouple while blowing off impurities.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1 to 14This invention provides a technical solution: a copper smelting furnace with an online detection device, comprising a furnace wall 1, a furnace body 2, and a feeding port 3. A side groove is formed on the furnace wall 1, and an arc-shaped body 4 is rotatably disposed within the side groove. An mounting block 8 is disposed on the furnace wall 1, and a first hydraulic rod 9 is rotatably connected to the mounting block 8. The first hydraulic rod 9 is rotatably connected to a mounting box 7 via a fixing bracket 10. The mounting box 7 is fixedly disposed within the arc-shaped body 4. A second hydraulic rod 11 is disposed at the top of the mounting box 7. A protective box 14 is fixedly connected to the output end of the second hydraulic rod 11. A thermocouple 15 is disposed within the protective box 14, and a blowing assembly 16 is disposed on the protective box 14. A device for monitoring is fitted onto the protective box 14 and the thermocouple 15. A cleaning component 12 is provided to clean residue from the protective box 14 and thermocouple 15. The cleaning component 12 is connected to the blowing component 16. A cooling component 13 is provided on the mounting box 7 to cool the interior of the protective box 14. A collection box 5 is located on the furnace wall 1 near the lower part of the arc-shaped body 4. An installation component 6 is provided on the furnace wall 1 for installing the collection box 5. In actual use, the parts extending into the furnace wall 1 can be made of heat-resistant materials, such as tungsten steel. Furthermore, high-temperature resistant springs are used to ensure the normal operation of the detection device. In actual use, the collection box 5 is used in conjunction with display instruments, recording instruments, and electronic regulators to facilitate online detection of the copper molten temperature. Cold air enters through the feeding port 3 and the connecting conduit 133, then into the protective box 14. Simultaneously, the cold air flows out from the air outlet on the protective box 14, cooling the components surrounding the protective box 14 and the thermocouple 15 inside, thus extending the service life of the thermocouple 15. As the protective box 14 moves upward, a blowing assembly 16, in conjunction with two rack plates 164 and gears 165, drives two piston rods 169 to push the gas from the two fixed chamber columns 1610 into the second annular tube 1212 and the first annular tube 127, respectively. A cleaning assembly 12 is also included to prevent... As the protective box 14 moves upward, the second annular tube 1212 moves downward on the protective box 14, and the first annular tube 127 moves downward on the thermocouple 15. With the cooperation of the blowing assembly 16 and the protective box 14, the second nozzle 1213 and the first nozzle 128 spray air onto the protective box 14 and the thermocouple 15 as they move downward. While cooling the surface of the protective box 14 and the thermocouple 15, the impurities on them are blown off. The impurities fall into the collection box 5. Pulling down the connecting horizontal plate 63 causes the sliding block 62 to move out of the slot on the limiting plate 61, which facilitates the installation and removal of the collection box 5 and the collection and treatment of impurities in the collection box 5.

[0033] like Figure 5 as well as Figure 6As shown, the cooling component 13 includes a blower 131, a vortex tube 132, and a connecting conduit 133. The blower 131 is fixedly installed on the upper end of the mounting box 7. The air outlet of the blower 131 is connected to the air inlet of the vortex tube 132. The cold air end of the vortex tube 132 is fixedly connected to the connecting conduit 133. The connecting conduit 133 extends into the mounting box 7 and is connected to the protective box 14. The bottom of the protective box 14 is provided with an air outlet. The arc-shaped body 4 is provided with a through groove for the thermocouple 15 to extend out. The protective box 14 is detachably connected to the connecting shell 141 by bolts. Both the protective box 14 and the connecting shell 141 are fixed inside. A snap-fit ​​plate 142 is installed to limit the thermocouple 15. The snap-fit ​​plate 142 on the protective box 14 and the connecting shell 141 engages and locks, limiting the thermocouple 15 and facilitating its installation. The blower 131 delivers gas to the vortex tube 132. The cold air enters the connecting conduit 133 from the cold air outlet of the vortex tube 132, and then enters the protective box 14. The cold air flows out from the air outlet on the protective box 14, which can cool the components around the protective box 14 and the thermocouple 15 inside the protective box 14, thereby improving the service life of the thermocouple 15.

[0034] like Figures 9 to 12As shown, the blower assembly 16 includes a vertical push rod 161 fixedly installed inside the mounting box 7 and a fixed connecting plate 163 fixedly installed on the protective box 14 via a connecting bracket. Two rack plates 164 are slidably connected to one end of the fixed connecting plate 163 near the protective box 14. A gear 165 meshes between the two rack plates 164, and the gear 165 is rotatably connected to the middle of the fixed connecting plate 163. The two rack plates 164 are located on opposite sides of one end of the fixed connecting plate 163. A connecting plate 168 is fixedly connected to the ends of the two rack plates 164 that are far apart from each other. A connecting plate 168 is fixedly connected to the upper end of the upper connecting plate 168. A vertical guide rod 162 is located directly below the vertical push rod 161. Limiting rods 166 are slidably inserted into the interior of both rack plates 164. The end of the limiting rod 166 away from the rack plate 164 is fixedly connected to the fixed connecting plate 163 via a connecting block. A return spring 167 is sleeved on the limiting rod 166, used to reset the rack plate 164. Piston rods 169 are fixedly connected to the ends of the two connecting plates 168 that are close to each other. Fixed cavity columns 1610 are slidably connected to both piston rods 169. The ends of the two piston rods 169 that extend into the fixed cavity columns 1610 are... A piston plate 1613 is fixedly connected, and the piston plate 1613 is slidably connected to the fixed cavity column 1610. The two fixed cavity columns 1610 are fixedly connected to the protective box 14 through the fixed sleeve plate 1611. The ends of the two fixed cavity columns 1610 that are far apart from each other are connected to an air outlet pipe 1612. The vertical push rod 161 contacts the vertical guide rod 162, pushing the connecting rod 121 to contact the connecting vertical plate 122. When the protective box 14 moves upward, since the fixed connecting plate 163 moves upward together with the protective box 14, the vertical guide rod 162 drives an upper rack plate 164 to slide downward on the fixed connecting plate 163 through the gear. 165 drives the lower rack plate 164 to slide upward, the limiting rod 166 slides into the rack plate 164, the return spring 167 is compressed, the two connecting plates 168 drive the piston plate 1613 to move in the fixed cavity column 1610 through the piston rod 169, and spray the gas in the fixed cavity column 1610 out of the gas outlet pipe 1612. The upper gas outlet pipe 1612 delivers the gas to the second annular pipe 1212, and the gas is sprayed out from the second nozzle 1213. The lower gas outlet pipe 1612 delivers the gas to the first annular pipe 127, and the gas is sprayed out from the first nozzle 128.

[0035] like Figure 6 , Figure 7 , Figure 8 as well as Figure 11As shown, the cleaning assembly 12 includes push rods 121 symmetrically installed on both sides of the inner wall of the mounting box 7, a second annular tube 1212 sleeved on the protective box 14, and a first annular tube 127 sleeved on the thermocouple 15. An upper vent pipe 1612 communicates with the second annular tube 1212, and a lower vent pipe 1612 communicates with the first annular tube 127. A first fixing horizontal plate 123 is symmetrically fixedly connected to the second annular tube 1212, and a connecting rod is fixedly connected to the upper end of the first fixing horizontal plate 123. Vertical plate 122 is located directly below push rod 121. A connecting strip 129 is fixedly connected to the upper end of the first fixed horizontal plate 123. A spring 1210 is fixedly mounted on the connecting strip 129. The spring 1210 is used to reset the second annular tube 1212 and the first annular tube 127. One end of the spring 1210, located in the middle, is fixedly connected to the protective box 14 via a fixing post 1211. A movable vertical rod 124 is fixedly connected to the lower end of the first fixed horizontal plate 123. A sliding connection is made to the movable vertical rod 124. A fixed square plate 125 is fixedly connected to the protective box 14. A second fixed horizontal plate 126 is fixedly connected to the lower end of the movable vertical rod 124. The second fixed horizontal plate 126 is fixedly connected to the first annular tube 127. Multiple first nozzles 128 are connected to the first annular tube 127, and multiple second nozzles 1213 are connected to the second annular tube 1212. Under the resistance of the pushing rod 121, the connecting vertical plate 122 drives the second nozzles 1213 to move downwards via the first fixed horizontal plate 123. Plate 123 drives the movable vertical rod 124 to slide on the fixed square plate 125. The first fixed horizontal plate 123 pulls the spring spring 1210 through the connecting strip 129 to drive the fixed column 1211 to retract. The movable vertical rod 124 drives the first annular tube 127 to move downward through the second fixed horizontal plate 126, thereby realizing that the second nozzle 1213 and the first nozzle 128 spray air on the protective box 14 and thermocouple 15 during the downward movement, cooling the surface of the protective box 14 and thermocouple 15 while blowing off the impurities on them.

[0036] like Figure 14 As shown, the installation component 6 includes a limiting plate 61 fixedly connected to the collection box 5. A limiting groove is provided on the furnace wall 1 for the limiting plate 61 to extend into. A sliding block 62 is slidably connected in the limiting groove. A slot is provided on the limiting plate 61 for the sliding block 62 to engage. A connecting horizontal plate 63 is fixedly connected to the lower end of the sliding block 62. A connecting spring 64 is fixedly connected to the upper end of the connecting horizontal plate 63. The upper end of the connecting spring 64 is fixedly connected to the furnace wall 1. When impurities fall into the collection box 5, the connecting horizontal plate 63 is pulled down, causing the sliding block 62 to move out of the slot on the limiting plate 61. This facilitates the installation and disassembly of the collection box 5 and the collection and processing of impurities in the collection box 5.

[0037] In practical use, when it is necessary to detect the temperature of molten steel, the first hydraulic rod 9 is activated to push the fixed frame 10, which in turn drives the arc-shaped body 4 to rotate on the furnace wall 1. The through groove on the arc-shaped body 4 rotates into the furnace wall 1. The second hydraulic rod 11 is activated to drive the protective box 14 and the thermocouple 15 downward, so that the thermocouple 15 can detect the temperature of the molten steel. The blower 131 is activated, and the blower 131 delivers gas to the vortex tube 132. The cold air enters the connecting conduit 133 from the cold air outlet of the vortex tube 132, and then enters the protective box 14. The cold air flows out from the air outlet on the protective box 14, which can cool the components around the protective box 14 and the thermocouple 15 inside the protective box 14, thereby improving the temperature. The service life of thermocouple 15 is measured when the test ends. The second hydraulic rod 11 moves thermocouple 15 into the mounting box 7 and stops. The first hydraulic rod 9, through the mounting box 7, rotates the arc-shaped body 4 out of the furnace wall 1. At this time, the collection box 5 is directly below the mounting box 7. The second hydraulic rod 11 again moves the protective box 14 upwards. The vertical push rod 161 contacts the vertical guide rod 162, pushing the connecting rod 121 to contact the connecting vertical plate 122. When the protective box 14 moves upwards, the fixed connecting plate 163 moves upwards along with the protective box 14. The vertical guide rod 162 drives an upper rack plate 164 to slide downwards on the fixed connecting plate 163, and through the gear 165, drives a lower rack plate 164 to slide upwards, thus limiting the movement. The insertion rod 166 slides into the rack plate 164, compressing the return spring 167. The two connecting plates 168, via the piston rod 169, drive the piston plate 1613 to move within the fixed cavity column 1610, causing the gas within the fixed cavity column 1610 to be ejected from the outlet pipe 1612. The upper outlet pipe 1612 delivers the gas to the second annular pipe 1212, where it is ejected from the second nozzle 1213. The lower outlet pipe 1612 delivers the gas to the first annular pipe 127, where it is ejected from the first nozzle 128. Simultaneously, under the resistance of the pushing rod 121, the connecting vertical plate 122, via the first fixed horizontal plate 123, drives the second nozzle 1213 to move downwards. 123 drives the movable vertical rod 124 to slide on the fixed square plate 125. The first fixed horizontal plate 123 pulls the spring spring 1210 through the connecting strip 129 to drive the fixed column 1211 to retract. The movable vertical rod 124 drives the first annular tube 127 to move downward through the second fixed horizontal plate 126. This enables the second nozzle 1213 and the first nozzle 128 to spray air onto the protective box 14 and the thermocouple 15 during the downward movement. While cooling the surface of the protective box 14 and the thermocouple 15, the impurities on them are blown off. The impurities fall into the collection box 5. Pulling down the connecting horizontal plate 63 causes the sliding block 62 to move out of the slot on the limiting plate 61, which facilitates the collection and processing of impurities in the collection box 5.
