[0002] The lining of a smelting furnace refers to the refractory material layer inside the furnace. It is primarily used to protect the furnace structure, withstand high temperatures and chemical corrosion, and provide necessary thermal insulation for the smelting process. The quality and performance of the lining directly affect the efficiency, service life, and safety of the furnace. A wear monitoring sensor is a device used to monitor the wear and tear of the lining in real time. This device typically uses induction technology to assess the condition and remaining life of the lining by detecting parameters such as temperature, thickness, and electrical conductivity.
[0003] The gases and molten metal produced during the smelting process in a smelting furnace can be corrosive, eroding sensor materials and affecting their performance and lifespan. Under high temperatures and harsh environments, sensors are prone to damage and failure, making it impossible to accurately monitor the furnace's lining. This makes regular maintenance and calibration of sensors difficult, increasing the complexity of equipment management.
[0004] Therefore, a smelting furnace lining loss monitoring sensing device is proposed. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0028] See also Figures 1 to 6 , is an embodiment provided by the utility model: a smelting furnace lining loss monitoring sensing device, comprising a flame retardant protective housing 1 and a control switch 2, the control switch 2 being fixedly mounted on the inner wall of the flame retardant protective housing 1, the interior of the flame retardant protective housing 1 being rotatably connected to a door panel 3, and the interior of the flame retardant protective housing 1 being provided with a maintenance trigger component for convenient maintenance processing, wherein:
[0029] The maintenance and inspection trigger assembly includes a magnetic plate 41, which is fixedly connected to the inside of the flame-retardant protective shell 1. An iron block 42 is fixedly connected to the lower inner wall of the door panel 3. The iron block 42 and the magnetic plate 41 are located on the same longitudinal center line. Grooves 45 are provided in the middle of both sides of the inner wall of the flame-retardant protective shell 1. The inner walls of the grooves 45 on both sides are slidably connected with cross plates 44. The middle of both sides of the cross plates 44 are sleeved with toggle sleeves 43. The bottom ends of the toggle sleeves 43 on both sides are attached to the inner wall of the door panel 3. An infrared temperature sensor 46 is provided above the cross plates 44. Right-angle grooves 47 are provided on both sides of the inner wall of the flame-retardant protective shell 1. The outer wall of the door panel 3 is slidably connected to the inner wall of the right-angle groove 47.
[0030] Wherein: the material of the flame retardant protective shell 1 is set to silicon carbide;
[0031] Better: the flame retardant protective shell 1 and the infrared temperature sensor 46 are installed at the edge of the inner wall of the furnace mouth of the smelting furnace. The infrared temperature sensor 46 is stored inside the flame retardant protective shell 1 during the process of monitoring and sensing the loss of the lining of the smelting furnace to avoid being affected by high temperature. When the infrared temperature sensor 46 needs to be maintained and inspected, the magnetic plate 41 can be energized by the control switch 2, and then the iron block 42 can be attracted to drive the door panel 3 to be converted from a vertical state to an inclined state along the right-angle groove 47. As the door panel 3 tilts and moves, its inner wall will come into contact with the toggle sleeves 43 on both sides, squeezing it into an inclined state, and then the horizontal plate 44 can be pushed outward along the groove 45, so that the infrared temperature sensor 46 can be pushed out to the outside of the flame retardant protective shell 1.
[0032] A hook post 48 is fixedly connected to the rear side of the inner wall of the flame-retardant protective housing 1. A traction spring 49 is fixedly connected to the outer wall of the hook post 48. The end of the traction spring 49 away from the hook post 48 is fixedly connected to the bottom of the horizontal plate 44. A receiving seat 410 is fixedly connected to the rear side of the inner wall of the flame-retardant protective housing 1. The inner wall height of the receiving seat 410 corresponds to the height of the horizontal plate 44.
[0033] Wherein: the hook 48 and the receiving seat 410 are located on the same longitudinal straight line;
[0034] Better: As the horizontal plate 44 moves outward, the traction spring 49 will be tensilely deformed, and with the cooperation of the hook column 48, the movement of the horizontal plate 44 can be more stable. The setting of the receiving seat 410 can dock with the horizontal plate 44 when it is reversed and recovered to the inside of the flame retardant protective shell 1, making the top placement more stable.
[0035] A clamping and positioning assembly for positioning and preventing deviation of the infrared temperature sensor 46 is provided in the middle of the horizontal plate 44, wherein:
[0036] The clamping and positioning assembly includes a fan blade 51, which is rotatably connected to the bottom of the horizontal plate 44. The middle part of the fan blade 51 passes through the horizontal plate 44 and is fixedly connected to a special-shaped cam 52. Guide grooves 55 are provided at the four corners of the top of the horizontal plate 44. The inner walls of the guide grooves 55 on both sides are slidably connected to movable plates 53. The middle parts of the outer walls of the movable plates 53 on both sides are fixedly connected to connecting springs 54 and connected. Clamping blocks 56 are fixedly connected to both sides of the top of the movable plates 53 on both sides. The inner walls of the clamping blocks 56 on both sides are attached to the outer walls of the infrared temperature sensor 46. The control switch 2 is electrically connected to the magnetic plate 41, the infrared temperature sensor 46 and the fan blade 51.
[0037] Among them: the special-shaped cam 52 is a symmetrical staggered splicing arrangement of two semicircular wheels, and the vertical section of the movable plate 53 is π-shaped;
[0038] Better: by controlling the switch 2 to control the fan blade 51 to rotate at the bottom of the horizontal plate 44, it can drive the special-shaped cam 52 to rotate. After it rotates ninety degrees from the horizontal state, its outer walls on both sides can push the movable plates 53 on both sides to move on the inner walls of the guide groove 55. The connecting springs 54 on both sides can limit the movable plates 53 on both sides to avoid sliding deviation, complete the adjustment of the spacing size, and then firmly fix the infrared temperature sensor 46.
[0039] The above implementation works as follows:
[0040] The steps for running the job are as follows:
[0041] The flame retardant protective housing 1 and the infrared temperature sensor 46 are installed at the edge of the inner wall of the furnace mouth of the smelting furnace. In the process of monitoring and sensing the loss of the lining of the smelting furnace, the infrared temperature sensor 46 is stored in the interior of the flame retardant protective housing 1 to avoid being affected by high temperature. When it is necessary to perform maintenance and inspection on the infrared temperature sensor 46, the magnetic plate 41 can be energized by the control switch 2, and then the iron block 42 can be attracted to drive the door panel 3 to be converted from a vertical state to an inclined state along the right-angle groove 47. As the door panel 3 tilts, its inner wall will come into contact with the toggle sleeves 43 on both sides, squeezing it into an inclined state, so that the horizontal plate 44 can be moved. The infrared temperature sensor 46 is pushed outward along the groove 45 to the outside of the flame-retardant protective housing 1. As the horizontal plate 44 moves outward, the traction spring 49 is stretched and deformed. With the cooperation of the hook column 48, the movement of the horizontal plate 44 is made more stable. The receiving seat 410 is provided to dock with the horizontal plate 44 when it is reversely recovered into the flame-retardant protective housing 1, making the top placement more stable and facilitating maintenance operations for maintenance personnel without having to reach into the smelting furnace and the flame-retardant protective housing 1. The infrared temperature sensor 46 can be regularly maintained and calibrated, thereby optimizing the convenience of equipment management.
[0042] By controlling the switch 2 to control the fan blades 51 to rotate at the bottom of the horizontal plate 44, the special-shaped cam 52 can be driven to rotate. After it rotates ninety degrees from the horizontal state, the outer walls on both sides can push the movable plates 53 on both sides to move on the inner walls of the guide groove 55. The connecting springs 54 on both sides can limit the movable plates 53 on both sides to avoid sliding deviation, complete the adjustment of the spacing size, and then firmly fix the infrared temperature sensor 46 to ensure that it can be sufficiently stable during the adjustment, push out and retract, and prevent it from slipping and causing damage. In addition, during the adjustment process, the fan blades 51 can be driven to rotate inside the flame retardant protective shell 1 to blow away the higher internal heat, so that the internal accumulated heat can be discharged in real time to avoid affecting the infrared temperature sensor 46, thereby extending its service life.
