Description

Technical Field

[0001] The utility model belongs to the technical field of copper smelting, and particularly relates to a temperature measuring device for an anode furnace. Background Art

[0002] In the prior art, the temperature of the molten copper in the anode furnace is usually measured by sampling from the copper outlet after the molten copper or copper slag is poured. The temperature data of the molten liquid in the furnace measured in this way is lagging and cannot meet today's high-quality production needs. The temperature in the anode furnace is as high as 1400°C, and the existing temperature measuring equipment cannot perform continuous temperature measurement under this temperature environment. Therefore, during copper smelting, an observation hole is opened on the anode furnace body. When the molten copper liquid level is below the observation hole, an infrared temperature measuring instrument is used to measure the temperature of the furnace through the observation hole outside the anode furnace body. However, since the liquid surface in the furnace is filled with flowing air and natural gas, the accuracy of the temperature measurement cannot be guaranteed. Utility Model Content

[0003] The utility model aims to provide an anode furnace temperature measuring device which can measure the temperature of molten copper in real time and accurately.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is: a temperature measuring device for an anode furnace, including a three-way joint, a side passage of the three-way joint is connected to a redox gas source, a straight passage is connected to an outer end of an air supply pipe, and another straight passage is connected to a window mounting tube. The window mounting tube is a straight tube, and the other end of the window mounting tube is connected to a probe mounting tube. The temperature measuring probe is accommodated in the probe mounting tube and the detection direction of the probe is parallel to the tube core of the window mounting tube.

[0005] Compared with the prior art, the utility model has the following technical effects: during the production process of the anode furnace, the redox gas is fed into the molten copper water through the air supply pipe, and the temperature measuring probe arranged on the outside of the redox gas inlet will not affect the delivery of the redox gas. At the same time, the redox gas can also purge the area in front of the temperature measuring probe to avoid dust particles in the furnace blocking the temperature measuring probe and prevent the molten body in the furnace from flowing out and causing the probe to be damaged due to high temperature, so that the temperature measuring probe can directly collect information of the molten copper water for analysis, thereby ensuring the real-time and accuracy of the temperature measurement.

DETAILED DESCRIPTION

[0010] The specific implementation of the utility model is further described in detail below through the description of embodiments in conjunction with the accompanying drawings.

[0011] An anode furnace temperature measuring device, as shown in the attached Figure 1 , 2 As shown, it includes a three-way joint 10, a window installation tube 20, and a probe installation tube 30 connected in sequence. Among them, the side passage 12 of the three-way joint 10 is used to communicate with the redox gas source, one straight passage is connected to the outer end of the air supply pipe, and the other straight passage is connected to the window installation tube 20. The other end of the window installation tube 20 is connected to the probe installation tube 30, and the temperature probe 41 is accommodated in the probe installation tube 30. Among them, the air supply pipe is inserted and fixed at the air outlet of the furnace body, penetrates the furnace wall of the anode furnace and extends into the furnace cavity. The straight tube cavity of the three-way joint 10 and the tube cavity of the window installation tube 20 should be connected with the air supply pipe and form a passage for the temperature probe 41 to detect. In this embodiment, the window installation tube 20 is a straight tube, the tube core of the window installation tube 20 is parallel to the tube core of the three-way joint 10, and the detection direction of the temperature probe 41 is also parallel to the tube core of the window installation tube 20.

[0012] In a more preferred solution, in order to facilitate positioning and installation and ensure the reliability of the detection path on the front side of the temperature measuring probe 41, the window installation tube 20 and the three-way connector 10 are arranged in a straight and coaxial manner. Figure 2 As shown, the window installation tube 20 is flange-connected with the three-way structure 10. Specifically, a flange 21 is provided at one end of the window installation tube 20, and a flange 2 11 is provided at a straight-through port of the three-way joint 10 corresponding to the flange 21. The middle part of the flange 21 is recessed toward the tube body of the window installation tube 20 to form a recess 22 for accommodating the window glass. The inner diameter of the recess 22 is larger than the inner diameter of the straight-through pipe opening of the three-way joint 10, and the inner diameter of the window installation tube 20 is smaller than the inner diameter of the straight-through pipe opening of the three-way joint 10. Specifically, the distance between the end face of the straight pipe connected between the three-way joint 10 and the window installation tube 20 and the bottom end face of the recess 22 should match the thickness of the window glass, so that in the use state, the two side end faces of the window glass are respectively pressed and fitted with the tube end of the three-way joint 10 and the bottom end face of the recess 22, so that its axial positioning can be achieved. The outer contour of the window glass matches the inner contour of the recess 22, so that its radial positioning can be achieved.

[0013] In order to facilitate cleaning of the air supply pipe when it is blocked, in this embodiment, the three-way connector 10 is detachably connected to the air supply pipe, as shown in the attached figure. Figure 2 As shown, the straight-through port of the three-way joint 10 away from the window mounting tube 20 is provided with an internal thread that matches the outer end of the air supply pipe.

[0014] As attached Figure 2 As shown, the tube core of the side passage 12 of the three-way joint 10 is arranged adjacent to the flange 21, which can increase the length of the connecting pipe section between the three-way joint 10 and the air supply pipe, and also arrange the gas inlet adjacent to the window, which can prevent dust particles from adhering to the window, thereby ensuring the accuracy of detection.

[0015] To facilitate the installation of the temperature probe 41, the probe installation tube 30 includes a detachably connected positioning tube 31 and a sleeve 32. One end of the positioning tube 31 is connected to the window installation tube 20, and the other end is internally positioned and connected to the temperature probe 41 and externally connected to the sleeve 32. The cable 42 connected to the tail end of the temperature probe 41 passes through the sleeve 32 and is led outward.

[0016] The positioning tube 31 is coaxially arranged with the window mounting tube 20. The positioning tube 31 and the window mounting tube 20 are connected by a tube clamp, and the tube end of the positioning tube 31 adjacent to the window mounting tube 20 protrudes outward along its radial direction to form a positioning ring 1 311, and the adjacent tube end of the window mounting tube 20 is correspondingly provided with a positioning ring 23, and the outer contours of the positioning ring 1 311 and the positioning ring 23 are consistent, and the tube clamp clamps the positioning ring 1 311 and the positioning ring 23 to limit the relative displacement of the two.

[0017] A lead tube 321 is provided on the tube body of the sleeve 32 , and the tube core is arranged at an angle with the positioning tube 31 . The lead tube 321 is arranged at an obtuse angle with the front tube body of the sleeve 32 .

[0018] When in use, the cable 42 connected to the tail end of the temperature probe 41 is first passed backward from the front end of the sleeve 32 and led out from the lead tube 321, and then the temperature probe 41 and the positioning tube 31 are fixedly connected, and then the sleeve 32 is sleeved on the positioning tube 31, so that the installation and positioning of the temperature probe 41 can be conveniently and reliably achieved. In this embodiment, the temperature probe 41 and the positioning tube 31 are threadedly connected and arranged coaxially, so that the installation and removal operations of the temperature probe 41 are convenient and the positioning is reliable.
