Description

Technical Field

[0001] The utility model belongs to the technical field of copper rod production, in particular to a melting furnace for copper rod production. Background Art

[0002] In the process of producing semi-finished copper wire or finished copper wire, a certain process is required to first prepare the electrolytic copper raw material into an oxygen-free copper rod with a diameter of 3mm or 8mm, and then make the oxygen-free copper rod into copper wire through processes such as wire drawing. When producing oxygen-free copper rods, the electrolytic copper raw material must first be melted into copper liquid through a melting furnace.

[0003] A Chinese patent document with authorization announcement number CN220083641U discloses a vertical melting furnace for copper wire production. After raw materials are added into the boiler through a feed port, the raw materials in the boiler are heated by a heating layer arranged below the boiler, and the raw materials are stirred by a stirring rod rotating with a connecting rod to accelerate the melting speed of the raw materials.

[0004] However, in the prior art, after raw materials of different sizes enter the melting furnace, it is difficult to evenly distribute them in the melting furnace for heating, and it is difficult to grasp the timing of stirring the raw materials. Stirring too early may easily cause the inside of the melting furnace to be scratched by the raw materials, while stirring too late is not conducive to accelerating the melting of the raw materials. Therefore, a melting furnace for copper rod production is proposed. Utility Model Content

[0012] Preferably, the bottom side of the furnace body is semicircular.

[0013] Preferably, the feed bin is rotatably connected to the bin cover.

[0014] The beneficial effects of the utility model are as follows: it is convenient to retain raw materials of different sizes in different areas through the melting piece, so that the raw materials of smaller sizes that are easy to melt can radiate heat to the raw materials of larger sizes during the process of being heated and melted first, thereby ensuring that all the raw materials can be melted and avoiding the raw materials of larger sizes from contacting the stirring component, so that the staff can observe the appearance changes of these raw materials through the feeding piece and accurately grasp the working timing of the stirring component.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0026] The present invention is further described below by way of embodiments in conjunction with the accompanying drawings.

[0027] like Figure 1-Figure 6 As shown, a melting furnace for copper rod production comprises a melting material component 1 which can melt raw materials quickly and evenly and prevent unmelted raw materials from being mixed into molten copper liquid, a stirring component 2 which can stir the molten copper liquid to make the temperature rise uniformly at various places inside the melting furnace, a stop valve 3 which can control the on-off of the pipeline at the discharge end of the melting furnace is arranged on one side of the melting material component 1, and an exhaust joint 4 which can guide the exhaust gas generated in the raw material melting process to the outside of the melting furnace is arranged above the melting material component 1.

[0028] In this embodiment: the melt assembly 1 includes a melting part that can retain raw materials of different sizes and specifications in different regions and heat the raw materials in different regions together, a heating part that can stably support the melting part and make the raw materials in it evenly heated, and a feeding part that can easily add materials to the melting part. The heating part includes a base 101, and the front and rear sides of the base 101 are fixedly connected to the inspection plate 102, and the two sides of the base 101 are fixedly connected to the arc frame 103, and the arc frame 103 is fixedly connected to the support 104, and the height A heat pipe 105 is fixedly installed between the supports 104 with the same vertical and horizontal positions, the melting part includes a furnace body 106 fixedly installed in the base 101, a material blocking net 107 is fixedly connected to the upper side of the furnace body 106, and a feeding part includes a feeding bin 108 fixedly connected to the top of the furnace body 106, a bin cover 109 is movably installed in front of the feeding bin 108, and windows 110 are fixedly installed on both sides of the bin cover 109; the bottom side of the furnace body 106 is semicircular, and the feeding bin 108 is rotatably connected to the bin cover 109;

[0029] The base 101 provides installation positions for the inspection plate 102, the curved frame 103, the furnace body 106 and other components. The removable inspection plate 102 allows the staff to conveniently and regularly inspect the heat pipe 105 arranged in the base 101 and ensure the cleanliness of the environment where the heat pipe 105 is located. The heat pipe 105 is installed between the curved frames 103 through the support 104, and the heat pipe 105 can be evenly surrounded by the bottom side of the furnace body 106. The silo 108, silo cover 109, window 110 and other components create a relatively closed environment for melting electrolytic copper raw materials. The opening and closing of the feed end of the melting furnace is controlled by rotating the silo cover 109 relative to the feed silo 108. The raw materials injected into the furnace body 106 through the feed silo 108 are intercepted by the intercepting net 107, so that only the raw materials that can pass through the intercepting net 107 can fall into the furnace body 106. The retention amount of raw materials on the intercepting net 107 and the changes in appearance can be observed through the window 110.

[0030] In this embodiment: the stirring component 2 includes a shaft seat 201 fixedly connected to both sides of the furnace body 106, a rotating shaft 202 is movably connected between the shaft seats 201, an agitator 203 is fixedly connected to the outer side of the rotating shaft 202, and a motor 204 is fixedly connected to one end of the rotating shaft 202; the shaft seat 201 is rotatably connected to the rotating shaft 202; the rotating shaft 202 is installed in the furnace body 106 through the shaft seat 201, and the rotating shaft 202 is driven to rotate relative to the shaft seat 201 by the motor 204, and the rotation of the output end of the motor 204 is transmitted to the agitator 203 through the rotating shaft 202, so that the agitator 203 can rotate around the axis of the rotating shaft 202 at a certain speed.

[0031] Working principle: When the melting furnace is installed and used for copper rod production, after the exhaust joint 4 is connected to the exhaust gas treatment equipment, the bin cover 109 is opened to put the electrolytic copper raw materials that are crushed or cut into a certain specification into the feed bin 108. Under the interception effect of the blocking net 107, the raw materials that can pass through the blocking net 107 will fall to the bottom area of ​​the furnace body 106, and the other raw materials will remain on the blocking net 107. After the raw materials are added, the bin cover 109 can be locked and the heat pipe 105 can be used to heat the raw materials at the bottom of the furnace body 106. As the temperature of this part of the raw materials increases, its temperature The raw materials on the material blocking net 107 are gradually radiated to increase the temperature of the raw materials. When the raw materials on the material blocking net 107 show signs of melting through the viewing window 110, it means that the raw materials in the furnace body 106 have basically turned into copper liquid. At this time, the motor 204 can drive the stirrer 203 to rotate, thereby stirring the copper liquid to make the temperature of each part in the furnace body 106 tend to be consistent. When the raw materials on the material blocking net 107 gradually melt and drip into the copper liquid, the particle size of this part of the raw materials will gradually decrease until they can pass through the material blocking net 107 and fall into the copper liquid, and are quickly melted by the high-temperature copper liquid.

[0032] When the motor 204 can work, the stop valve 3 can be opened appropriately to allow the copper liquid to flow out slowly at a certain speed, or when there is no more raw material left on the blocking net 107, the stop valve 3 can be fully opened to allow the copper liquid to flow out quickly. In addition, during the entire process of melting the raw materials, the exhaust joint 4 can be connected to the exhaust gas treatment equipment to extract and purify the exhaust gas generated in the melting furnace.

[0033] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
