The cylinder door 2, which is hinged to the inner rear end of the heat-insulating cylinder 1, and the water tank 8 located on the lower right side of the heat-insulating cylinder 1 are fitted together. When the cylinder door 2 is closed... Symmetrically arranged on the heat insulation cylinder 1, and a limiting block 3 that is damped and rotatedly connected to the heat insulation cylinder 1 is attached to the rear side of the upper inner end of the cylinder door 2. A flow connection structure is provided between the heat insulation cylinder 1 and the water tank 8, and a waste heat utilization structure is provided inside the water tank 8. The flow connection structure includes a transfer pipe 9, a first solenoid valve 10, a pump 11, a mounting plate 12, a return pipe 13, and a second solenoid valve 14. The first solenoid valve 10 is fixedly installed on the inner side of the left end of the water tank 8. The waste heat utilization structure includes a heat exchange cylinder 15, a baffle plate 16, and a heat exchange plate 17. The heat exchange cylinder 15 is fixedly installed on the inner side of the middle part of the water tank 8.

[0028] Inside the heat insulation cylinder 1, support mesh 4 is fixedly connected at equal intervals and nested with the cylinder door 2. A bearing plate 5 is attached to the upper surface of the middle part of the support mesh 4. A heating pipe 6, which is fixedly installed in the heat insulation cylinder 1, is snapped through the inner side of the outer end of the bearing plate 5. The heating pipe 6 is symmetrically arranged about the middle of the heat insulation cylinder 1. A thermometer 7 is embedded in the inner side of the upper rear end of the heat insulation cylinder 1. A transfer pipe 9 is threaded between the heat insulation cylinder 1 and the first solenoid valve 10. A pump 11 connected to the right side of the water tank 8 is installed.

[0029] To address the problems in existing technologies, such as the inconvenience of handling magnetic cores during production, difficulty in controlling the sintering temperature, limited sintering results, and difficulty in recovering and utilizing residual heat from sintering, leading to resource waste, this embodiment employs the following technical solution: Figure 1 , Figure 2 and Figure 3 First, the operator can control the operation of the heating tubes 6, which are symmetrically fixed in the center of the heat insulation cylinder 1, via the controller 20 embedded in the upper right inner side of the water tank 8, depending on whether preheating is required. Then, the operator can rotate the limiting block 3, which is connected to the damping block 3 at the upper rear side of the heat insulation cylinder 1, to disconnect the limiting block 3 from the hinged cylinder door 2 inside the heat insulation cylinder 1. Next, the cylinder door 2 can be rotated outward to disconnect the closed connection between the cylinder door 2 and the heat insulation cylinder 1. Then, the carrier plate 5, on which the shaped magnetic core is placed, can be removed and placed inside the heat insulation cylinder 1, so that the carrier plate 5 is attached to the heat insulation cylinder 1. The upper surface of the middle part of the inner equal-spaced fixed support net 4 can be rotated in sequence after placement, so that the lower end of the limit block 3 fits and limits the cylinder door 2. Then, the heating tube 6 symmetrically arranged in the center can be controlled by the controller 20 to perform the sintering operation on the magnetic core. The temperature display of the temperature measuring instrument 7 embedded in the inner side of the upper end of the heat insulation cylinder 1 can be observed to know the temperature inside the heat insulation cylinder 1. The controller 20 can then control the operation of the heating tube 6, thereby controlling the sintering temperature of the magnetic core and making the sintering effect of the equipment better.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 After the magnetic core is sintered, the controller 20 can control the operation of the second solenoid valve 14 and the first solenoid valve 10, which are fixedly installed on the inner side of the upper end of the heat insulation cylinder 1 and the inner side of the left end of the water tank 8, respectively. This allows the lower ends of the heat insulation cylinder 1 and the water tank 8 to be connected to the first solenoid valve 10 via the transfer pipe 9, and the upper end of the heat insulation cylinder 1 to be connected to the return pipe 13 via the second solenoid valve 14. The controller 20 can then control the pump 11 installed on the mounting plate 12 to operate. Since the pump 11 is connected to the right side of the water tank 8 and the return pipe 13 is connected to the external thread of the pump 11, the operation of the pump 11 facilitates the hot gas in the heat insulation cylinder 1 to enter the water tank 8 through the transfer pipe 9 and then return to the heat insulation cylinder 1 through the return pipe 13, thus achieving circulation.

[0031] like Figure 1 , Figure 2 , Figure 4 and Figure 5 Because a heat exchange cylinder 15 is fixedly connected to the inner side of the middle of the water tank 8, and baffle plates 16 are interlaced and fixedly connected to it inside the heat exchange cylinder 15, and heat exchange plates 17 are interlaced and fixed outside the heat exchange cylinder 15, which are also interlaced with the baffle plates 16, it is convenient for hot air to circulate inside the heat exchange cylinder 15 through the baffle plates 16. It is also convenient for the water inside the outer end of the water tank 8 to be heated by the heat exchange performance of the heat exchange cylinder 15 and the heat exchange plates 17 themselves, so as to achieve the purpose of heat exchange and recovery of sintering waste heat and avoid resource waste. The controller 20 can control the temperature sensor 18 and the display 19 embedded in the water tank 8 to operate, so as to sense and display the water temperature in the water tank 8, so that the controller 20 can control the operation of the third solenoid valve 21 fixedly installed on the inner side of the rear end of the water tank 8 to circulate and drain the hot water in the water tank 8 for use. All the electrical components mentioned above are existing technologies and will not be described in detail here.
