Description

Technical Field

[0001] This utility model relates to the field of formaldehyde filtration technology, specifically to an annealing device for precious metal processing. Background Technology

[0002] Annealing furnaces for precious metals are primarily used to improve the crystal structure and properties of precious metal materials. Through heat treatment, the furnace eliminates internal stresses generated during processing, resulting in finer grains, thus improving the material's toughness and plasticity, reducing hardness, and making machining easier. Furthermore, the furnace removes impurities and gases from the metal, enhancing its purity and surface quality, thereby improving product stability and reliability. Precious metal annealing furnaces are widely used in gold and silver jewelry processing, gold and silver surface treatment, and quenching and tempering of precious metal alloys. Annealing significantly improves the quality and performance of precious metal materials, meeting the needs of various industrial applications.

[0003] Existing precious metal annealing equipment requires varying temperatures when processing precious metal wires of different thicknesses. As a result, the internal temperature of the annealing equipment is frequently switched according to the demand. However, while heating is easy, cooling is difficult. When it is necessary to cool down to a temperature suitable for processing a certain specification of precious metal wire, natural cooling is generally used, which is undoubtedly inefficient. Furthermore, the cooling capacity of the equipment is insufficient, thus inhibiting work efficiency.

[0004] Therefore, a solution is needed. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-7This utility model provides a technical solution to achieve this: it includes a heating tube sleeve 1, an annealing furnace body 2, a material tube 3, a support frame 4, a temperature sensor 5, a conduction tube 6, a controller 7, and a cooling box 8. The heating tube sleeve 1 is wrapped around the annealing furnace body 2, the support frame 4 is located inside the annealing furnace body 2, the material tube 3 is located above the support frame 4, the temperature sensor 5 is located in the middle of the support frame 4, the conduction tube 6 is inserted through the annealing furnace body 2 and located at the bottom of the temperature sensor 5, the cooling box 8 is wrapped around the annealing furnace body 2, and the controller 7 is located at the front end of the bottom of the cooling box 8.

[0029] The core cooling box 8 includes a box body 81, a fixing groove 82, several fixing plates 83, several heat dissipation fins 84, several cooling holes 85, and a cooling mechanism 86. The box body 81 has a rounded cuboid structure. The fixing groove 82 has an octagonal structure and is installed inside the box body 81. Several fixing plates 83 have a trapezoidal three-dimensional structure and are installed opposite each other at the upper and lower ends of the fixing groove 82. Several heat dissipation fins 84 are evenly arranged on each fixing plate 83. Several cooling holes 85 are evenly arranged on the left and right side walls of the fixing groove 82. The cooling mechanism 86 is located inside the box body 81.

[0030] The conductive tube 6 extends downward from the bottom of the temperature sensor 5 and the annealing furnace body 2 and bends into the cooling box 8 to connect with the controller 7. The heat dissipation fins 84 are of different sizes and are arranged in an arc shape on the fixing plate 83.

[0031] Specifically, the cooling mechanism 86 includes a cooling box 861, several cooling pipes 862, several transport pumps 863, several air boxes 864, several air ducts 865, and several powerful fans 866. The cooling box 861 is located at the bottom center inside the box body 81. Several air boxes 864 are oppositely arranged at the left and right ends of the fixed slot 82. Several air ducts 865 are equidistantly arranged on the side of each air box 864 away from the fixed slot 82. Several cooling pipes 862 are located at the rear end of the cooling box 861, pass through the air boxes 864, and reciprocate up and down through the air boxes 864. The tail end of the cooling pipe 862 is connected to the front end of the cooling box 861 and is located on the left and right sides of the conduction pipe 6. Several transport pumps 863 are wrapped around each cooling pipe 862 and are located at the rear end of the cooling box 861. Several powerful fans 866 are arranged on the left and right side walls of the cooling box 865 corresponding to each air duct 865 and are connected to each air duct 865. The bellows 864 has a hollow U-shaped three-dimensional structure and the side facing the fixed groove 82 and the part in contact with the air guide duct 865 are both connected. The air guide duct 865 has a hollow T-shaped three-dimensional structure and the front and rear ends are connected.

[0032] This design incorporates a novel cooling chamber 8. Coolant is repeatedly circulated within cooling pipes 862 via cooling chamber 861 to cool the interior of the air chamber 864. Subsequently, a powerful fan 866 draws in external air, propelling the cool air from the air chamber 866 along each cooling hole 85 to rapidly cool the annealing furnace body 2, which is fixed to the heat dissipation fins 84 within the mounting slot 82. Simultaneously, a temperature sensor 5 monitors the temperature inside the annealing furnace body 2 in real time and sends data to the controller 7. When cooling is required, an external controller sends a code to the controller 7, instructing it to operate the cooling chamber 861 until the temperature of the annealing furnace body 2 is reduced to the required level. This design significantly increases the cooling efficiency of the annealing furnace body 2.

[0033] Working principle: When the annealing furnace body 2 needs to be cooled, the external controller can transmit a signal to the cooling box 8 through the controller 7 to start the cooling box 8. The cooling box 8 transports the coolant by the transport pump 863 through the entire cooling pipe 862 to the air box 864 for rapid cooling. At the same time, the external controller controls the powerful fan 866 to introduce air through the air box 864 and spray the cold air through the cooling hole 85 to rapidly cool the annealing furnace body 2 until the required temperature is reached.

These components are all general standard parts or components known to those skilled in the art. The structure and principle of this invention are readily known to those skilled in the art through technical manuals or conventional experimental methods. The problem this invention solves is that existing precious metal annealing equipment requires varying temperatures depending on the thickness of the precious metal wire being processed. Consequently, the internal temperature of the annealing equipment frequently changes according to these requirements. While heating is easy, cooling is difficult. When cooling to a suitable temperature for processing a specific specification of precious metal wire is needed, natural cooling is typically used, which is undoubtedly inefficient. Even with cooling structures, the cooling effect is insufficient, further hindering efficiency. This invention significantly increases the cooling efficiency of the furnace body.
