[0028] like Figures 1 to 5As shown, a heat preservation furnace for copper alloy processing includes: a fixed box 1, which is open at one end. Inside the fixed box 1, a first heat insulation layer 101, a first heat preservation layer 102, and a placement layer 103 are arranged in sequence. The open end of the first heat preservation layer 102 is provided with multiple flow guide grooves 104; a flow guide 2 is disposed at the open end of the fixed box 1 to drive the flow of heat inside the placement layer 103; and a blocking member 3 is disposed inside the placement layer 103 to block impurities. Specifically, when heat preservation of metal, the metal is first placed inside the placement layer 103. Then, the metal is heat-preserved by the cooperation of the first heat insulation layer 101, the first heat preservation layer 102, and the placement layer 103 to prevent uneven cooling of the metal and deformation. Finally, the placement layer 103 is sealed by the flow guide 2 to ensure stable cooling of the metal. During the sealing process of the placement layer 103 by the flow guide 2, the heat inside the placement layer 103 is circulated to ensure uniform heat distribution inside the placement layer 103.
[0029] like Figures 1 to 5 As shown, the placement layer 103 is also equipped with multiple heating wires. The placement layer 103 also has multiple air guide grooves 105 and through holes. The air guide grooves 105 are located at the top of the placement layer 103, and the through holes are located at the bottom of the placement layer 103. Both the air guide grooves 105 and the through holes are connected to the flow guide grooves 104. Specifically, the heating wires can control the temperature inside the placement layer 103 during use; the air guide grooves 105 can guide the heat accumulated at the top of the placement layer 103 during use; the flow guide grooves 104 can guide the heat inside the placement layer 103 during use; and the through holes at the bottom can guide the heat at the top of the placement layer 103 during use, ensuring uniform temperature inside the placement layer 103.
[0030] like Figures 1 to 5As shown, the flow guide 2 includes a fixed cover 201, which is located at the opening end of the fixed box 1 and can rotate relative to the fixed box 1. A second heat insulation layer 202 and a second heat preservation layer 203 are sequentially provided on the side of the fixed cover 201 relative to the fixed box 1. The second heat preservation layer 203 has an air inlet 206 and an air outlet 208 respectively on the side of the fixed box 1, and the air inlet 206 and air outlet 208 correspond one-to-one with the flow guide groove 104. An air inlet groove 205 and an air outlet groove 207 are also provided inside the second heat preservation layer 203, which are connected to the air inlet 206 and air outlet 208 respectively. A volute fan 204 is rotatably connected inside the second heat preservation layer 203. Specifically, the fixed cover 201 and the fixed box 1 are connected by a hinge, facilitating the handling of metal components during use. Inside the component box placement layer 103, a fixed cover 201 and a fixed box 1 are added, which are made of cast iron or stainless steel, to protect the first insulation layer 101 and the second insulation layer 202 during use. The first insulation layer 101 and the second insulation layer 202 can be made of fiberglass wool or rock wool. The second insulation layer 203 and the placement layer 103 are both made of refractory cement or refractory bricks to ensure the stability of the metal insulation process. During use, the volute fan 204 can absorb the heat from the top of the placement layer 103 through the cooperation of the air inlet 206 and the air inlet groove 205, so that the hot air is discharged into the through hole through the exhaust groove 207 and the air outlet 208, ensuring the uniformity of heat during the insulation process of the placement layer 103. An electric motor is also provided on the outside of the fixed cover 201, which can drive the volute fan 204 to rotate during use.
[0031] like Figures 1 to 5 As shown, the blocking component 3 includes a sliding rod 301, which is T-shaped. There are multiple sliding rods 301, each corresponding to a through hole. The sliding rods 301 slide inside the through holes. Specifically, during use, the hot air driven by the volute fan 204 pushes the sliding rod 301 upward, allowing the hot air to be discharged into the placement layer 103 through the through holes. When the heat preservation is stopped, the sliding rod 301 moves downward along the through holes under the action of gravity, thereby sealing the through holes and preventing metal debris from entering the through holes and causing blockage. The outer side of the sliding rod 301 is coated with a heat insulation layer. The sliding rod 301 is made of high-temperature resistant foam material to ensure that hot air can blow the sliding rod 301 during use.
[0032] like Figures 1 to 5 As shown, a limiting block 304 and a retaining ring 302 are also provided on the outside of the sliding rod 301. The retaining ring 302 is sleeved on the outside of the sliding rod 301 and is connected to the through hole. The limiting block 304 is provided at the bottom of the sliding rod 301. Specifically, during use, the sliding distance of the sliding rod 301 is limited by the cooperation of the retaining ring 302 and the limiting block 304 to prevent the sliding rod 301 from sliding out of the through hole.
[0033] like Figures 1 to 5 As shown, the sliding rod 301 also has a groove 303 on its outer side. There are multiple grooves 303. Specifically, the grooves 303 can increase the flow rate of hot air inside the through hole during use, further ensuring the uniformity of temperature of the placement layer 103 during use.
[0034] like Figures 1 to 5 As shown, the working state of the copper alloy processing heat preservation furnace is as follows: When heat preservation of metal, the metal part is first placed inside the placement layer 103, and then the metal part is assisted in heat preservation by heating wire. During the heat preservation process, the heat inside the placement layer 103 is circulated by the cooperation of the guide groove 104, air inlet 206, air inlet groove 205, air outlet groove 207 and air outlet 208, so as to ensure the uniformity of the internal temperature of the placement layer 103 during use and avoid uneven cooling of the metal part during the heat preservation process.
[0035] In summary, this utility model includes: a fixed box 1, which is open at one end. Inside the fixed box 1, a first heat insulation layer 101, a first heat preservation layer 102, and a placement layer 103 are arranged in sequence. The opening end of the first heat preservation layer 102 is provided with multiple guide grooves 104; a guide member 2 is disposed at the opening end of the fixed box 1 to drive the flow of heat inside the placement layer 103; and a blocking member 3 is disposed inside the placement layer 103 to block impurities. Through the arrangement of the first heat preservation layer 102 and the guide member 2, this utility model achieves the control of the air accumulated at the top of the placement layer 103 by the cooperation of the first heat preservation layer 102, the guide grooves 104, the second heat preservation layer 203, the air inlet 206, the air inlet groove 205, the exhaust groove 207, and the air outlet 208, thus avoiding uneven temperature distribution. It also requires the use of an electric heating wire for auxiliary temperature control, thereby reducing energy consumption during the heat preservation process.
