Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy smelting technology, and in particular to an aluminum alloy melt temperature detection component and smelting equipment. Background Technology

[0002] Accurate detection of the melt temperature is crucial during the aluminum alloy smelting process. This helps operators precisely control the smelting temperature, ensuring uniform composition and stable performance of the aluminum alloy, avoiding defects such as porosity and cracks caused by temperature deviations, and improving the quality of aluminum alloy products.

[0003] In existing methods for detecting the temperature of molten aluminum alloy, the detection probe of the detector is mainly inserted into the solution manually. However, due to the high temperature of the solution, handheld detection is dangerous and cannot achieve real-time detection. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the inherent dangers of handheld detection and the lack of real-time detection capabilities, by proposing an aluminum alloy molten metal temperature detection component and smelting equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A component for detecting the temperature of molten aluminum alloy and a melting equipment, comprising:

[0007] The installation barrel has a limiting strip fixedly connected to one side of its outer wall and a toothed rack fixedly connected to the other side of its outer wall.

[0008] The mounting bracket is inserted into the mounting bucket;

[0009] A temperature detector is fixedly connected to the bottom of the mounting bracket, and the probe of the temperature detector extends to the bottom of the mounting barrel.

[0010] In one possible design, the mounting bracket has L-shaped grooves on both sides of the bottom, a top plate is slidably connected in the L-shaped groove, a spring is provided at the top of the L-shaped groove, and the two ends of the spring are welded to the top inner wall of the L-shaped groove and the top of the top plate, respectively. The bottom of the top plate has a slot.

[0011] In one possible design, two stop bars are fixed to the inner walls of both sides of the mounting barrel, and the two stop bars are respectively inserted into the corresponding L-shaped grooves and engage with the slots, so that the mounting frame can be detachably fixed inside the mounting barrel.

[0012] In one possible design, heat insulation cotton is fixedly installed on the bottom inner wall of the mounting barrel, and the heat insulation cotton covers the outer wall of the temperature detector to isolate the heat of the high-temperature molten liquid.

[0013] A smelting device includes an aluminum alloy molten metal temperature detection component and a furnace body. The top of the furnace body is covered with a cover plate, and an installation bucket slides through the cover plate. A drive motor is fixedly connected to the top of the cover plate, and a gear is rotatably connected inside the cover plate. The output shaft of the drive motor and one end of the gear are fixedly connected by a coupling. The gear meshes with a rack to drive the installation bucket to rise and fall, so that the probe of the temperature detector can be inserted into the molten metal inside the furnace body.

[0014] In one possible design, mounting plates are fixedly connected to both sides of the furnace body, and L-shaped supports are provided on both sides of the furnace body. One end of each mounting plate is rotatably connected to one end of each L-shaped support via a rotating shaft. An electric push rod is provided between the L-shaped support and the mounting plate, with the bottom of the electric push rod movably connected to the top of the L-shaped support and the top of the electric push rod movably connected to the bottom of the mounting plate. An L-shaped bracket is fixedly installed on one side of the furnace body, and a cylinder is fixedly inserted through the L-shaped bracket. The output shaft of the cylinder passes through the bottom of the L-shaped bracket and is fixedly connected to the top of the cover plate to control the lifting and lowering of the cover plate.

[0015] In this application, the temperature detector is fixed to the bottom of the mounting bracket with bolts. The mounting bracket, along with the temperature detector, is inserted into the mounting barrel, and the temperature detector is inserted into the insulation cotton. The probe of the temperature detector extends to the bottom of the mounting barrel. When the mounting bracket is inserted into the mounting barrel, the L-shaped groove fits onto the stop rod and rotates, pushing the top plate upward. The top plate compresses the spring. Then, the mounting bracket is rotated again, and the top surface of the stop rod contacts the slot. The pressure on the mounting bracket is released, and the top plate and the stop rod are pressed together. The spring returns to its original position, and the slot at the bottom of the top plate clamps and limits the stop rod. The aluminum alloy is placed into the furnace body, and the drive motor is started. The output shaft of the drive motor drives the gear to rotate. The gear meshes with the rack, driving the mounting barrel to descend through the guide bar, so that the probe at the bottom of the temperature detector extends into the solution. The temperature detector at the bottom of the mounting bracket is connected to the mounting bracket via a connecting wire. When the power is applied, the temperature detector monitors the solution. When the solution is heated and heat preservation is required, the cylinder is energized, and the output shaft of the cylinder on the L-shaped bracket extends, causing the cover plate to cover the top of the furnace body. As the cover plate is lowered, the drive motor is started, and the output shaft of the drive motor rotates in the opposite direction, driving the gear to rotate. The gear meshes with the rack and pinion, pushing the mounting bucket upward. The mounting bucket drives the mounting frame upward, and the temperature detector maintains the upward movement. When the cover plate is completely on the furnace body, the temperature detector also rises. During the upward movement, the PLC controller controls the drive motor and cylinder to ensure that the temperature detector probe is always inserted into the solution. The cylinder output shaft retracts, lifting the cover plate. The two electric push rods are energized, and their output shafts extend, supporting the furnace body on the mounting plate, allowing the furnace body to flip on the L-shaped support.

[0016] Beneficial effects: In this utility model, the aluminum alloy melt temperature detection component and smelting equipment achieve stable installation and flexible disassembly of the detection device by accurately installing the temperature detector at the bottom of the mounting frame and extending it into the mounting barrel, in conjunction with the locking structure of the L-shaped groove, top plate, spring and stop bar.

[0017] In this utility model, the aluminum alloy melt temperature detection component and smelting equipment, by means of a drive motor driving gear and rack meshing, can precisely control the lifting and lowering of the installation tank, so that the temperature detector probe is always deeply inserted into the solution, ensuring the accuracy of temperature detection and the flexibility of operation.

[0018] In this invention, the temperature detector is conveniently disassembled inside the mounting container. At the same time, the gear and rack can be used to adjust the temperature detector, and the height of the probe inserted into the solution can be kept constant, ensuring the real-time performance and stability of the detection data.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In one embodiment: Refer to Figures 1 to 4A temperature detection component for molten aluminum alloy comprises a cylindrical mounting barrel 8, with a fixing strip 11 welded to one outer wall and a fixing rack 13 welded to the other outer wall, ensuring that the fixing strip 11 and the rack 13 are parallel and at the same height. Insulating cotton 14, made of ceramic fiber, is pasted onto the inner bottom wall of the mounting barrel 8, completely covering the mounting area of ​​the temperature detector 19. A rectangular mounting bracket 12 is used to fix the temperature detector 19 at its bottom center with M6 bolts, ensuring that the probe of the temperature detector 19 extends vertically downwards to the bottom of the mounting barrel 8. L-shaped grooves 15 are symmetrically welded to the bottom of both sides of the mounting bracket 12, with a vertical arm length of 20mm and a horizontal arm length of 15mm.

[0026] Reference Figure 4 A top plate 16 is slidably installed in the L-shaped groove 15, and an arc-shaped slot 18 is opened at the bottom for locking. A compression spring 17 is installed on the top of the L-shaped groove 15. The free length of the spring 17 is 15mm. When compressed to 10mm, it generates a spring force of 5N. The two ends of the spring 17 are welded and fixed to the inner wall of the top of the L-shaped groove 15 and the top of the top plate 16 respectively through spring seats.

[0027] Reference Figure 3 Symmetrical baffles 20 are welded to the inner walls of both sides of the mounting barrel 8, with their horizontal positions aligned with the vertical arms of the L-shaped groove 15 and their vertical positions higher than the L-shaped groove 15. The mounting bracket 12, along with the temperature detector 19, is inserted from the top of the mounting barrel 8, allowing the L-shaped groove 15 to fit into the baffles 20. This pushes the top plate 16 upwards by the baffles 20, compressing the spring 17 to a stroke of 10mm. The mounting bracket 12 is then rotated until the top of the baffle 20 aligns with the slot 18. The mounting bracket 12 is then released, and the spring 17 returns to its original position, pushing the top plate 16 downwards, causing the slot 18 to lock the baffle 20 in place, thus securing the mounting bracket 12. At this point, the probe of the temperature detector 19 protrudes through the bottom opening of the mounting barrel 8, and the insulation cotton 14 completely covers the body of the temperature detector 19.

[0028] This application can be used in the field of aluminum alloy smelting, or in other fields applicable to this application.

[0029] In another embodiment: Reference Figure 1 This smelting equipment, applied in the field of aluminum alloy smelting, consists of a rectangular furnace body 1 with symmetrically welded mounting plates 4 on its two outer walls. L-shaped supports 2 are fixed to a horizontal base using M12 bolts. A rotating shaft connects the mounting plates 4 to the horizontal arms of the L-shaped supports 2, forming a flip-up structure. An electric push rod 3 is installed between the vertical arm of the L-shaped supports 2 and the mounting plate 4. The push rod 3 is connected to the L-shaped supports 2 at the bottom via a hinge and to the mounting plate 4 at the top via a ball joint. When the electric push rod 3 is fully retracted, the furnace body 1 is vertical.

[0030] Take a rectangular cover plate 7 and make a through hole in its center. Slide the cover plate 7 on the guide column at the top of the furnace body 1 through a linear bearing. Weld a drive motor 9 bracket to the top of the cover plate 7. The output shaft of the motor is connected to the gear 10 through a coupling. The rack 13 of the mounting barrel 8 is properly engaged. Weld an L-shaped bracket 5 to one side of the furnace body 1. Install a cylinder 6 on the horizontal arm of the L-shaped bracket 5. The piston rod end of the cylinder 6 is connected to the top of the cover plate 7 through a flange. When the cylinder 6 is fully extended, the cover plate 7 presses against the furnace body 1.

[0031] refer to Figure 1 Temperature detector 19 is connected to PLC controller via shielded cable, and drive motor 9 and cylinder 6 solenoid valve are connected to PLC controller via relay. The PLC program is set so that the mounting bucket 8 is raised or lowered according to the lifting or lowering of cover plate 7, ensuring that the probe of temperature detector 19 is always immersed in the molten metal; when the molten metal needs to be poured out, electric push rod 3 extends to tilt furnace body 1.

[0032] However, as is well known to those skilled in the art, the working principles and wiring methods of cylinder 6 and drive motor 9 are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0033] In this invention, the furnace body 1 can be the same as the CMQG600 aluminum melting furnace, and the temperature detector 19 can be the same as the Shenjie Instrument WRPWRN temperature sensor.

[0034] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
