[0033] The pressure pump supplies high-pressure gas into the interior of the heat preservation support device 1 through the injection port 302, thereby accelerating the fluidity of the molten metal.

[0034] Through the above technical solution, the solid metal or molten metal is placed inside the holding barrel 201, and a sealed space is formed by the cooperation of the sealing cover 301 and the heat preservation barrel 101. Then, a high pressure is applied to the interior of the heat preservation support device 1 from the injection port 302 through the pressure pump, and the high pressure is used to push the molten metal to quickly pass through the filtering holes 202 for filtration, achieving the effect of improving the filtration efficiency.

[0035] Specifically, a pressure relief valve 303 is further installed on the top of the sealing cover 301, and the pressure relief valve 303 communicates with the interior of the heat preservation barrel 101.

[0036] Through the above technical solution, the pressure relief valve 303 is provided on the sealing cover 301 to protect the heat preservation support device 1. When the internal pressure of the heat preservation support device 1 is too high, the excess pressure is discharged through the pressure relief valve 303 to prevent the interior of the heat preservation support device 1 from always being under high pressure and exploding.

[0037] Specifically, a suspension handle 203 is fixedly connected to the top of the holding barrel 201. The suspension handle 203 is wound around the top of the holding barrel 201 in a corrugated shape, and a plurality of hook holes are formed between the suspension handle 203 and the top of the holding barrel 201.

[0038] Through the above technical solution, the function of setting the suspension handle 203 on the holding barrel 201 is to facilitate the removal of the holding barrel 201. By using a hook in cooperation with the suspension handle 203 and through a lifting device, the holding barrel 201 can be taken out for filling or cleaning.

[0041] Specifically, the heat preservation support device 1 includes a heat preservation barrel 101.

The provided discharge port 102 is used to discharge the filtered molten metal. When filtering the molten metal, the discharge port 102 can be sealed by the sealing device 103 to increase the pressure inside the heat preservation barrel 101, or the discharge port 102 can be kept open to allow the molten metal to flow out continuously.

[0043] Specifically, a supporting boss 104 is fixedly connected inside the heat preservation barrel 101. A cavity 105 is formed inside the supporting boss 104, and a heating device 106 is fixedly connected inside the cavity 105.

[0044] A power supply junction box 107 is fixedly connected to the outer surface of the heat preservation barrel 101. The power supply junction box 107 is connected to an external power supply to supply power to the heating device 106.

[0045] Through the above technical solution, the provided supporting boss 104 is used to support the containing barrel 201. And because the supporting boss 104 is provided, the thickness is increased, which can be used to form the cavity 105, and the heating device 106 is installed inside the cavity 105 to heat the containing barrel 201, so that the molten metal inside the containing barrel 201 can maintain a continuous high temperature.

[0046] The power supply junction box 107 has an adjustment function. In addition to supplying power to the heating device 106, it can also adjust the temperature of the heating device 106, so that the heating device 106 can be set according to needs.

[0047] Specifically, the containing barrel 201 includes an upper barrel and a lower barrel. The upper barrel and the lower barrel are fixedly connected. The diameter of the upper barrel is equal to the inner diameter of the heat preservation barrel 101, and the diameter of the lower barrel is equal to the inner diameter of the supporting boss 104. And the bottom of the upper barrel is lapped on the top of the supporting boss 104.

[0048] Through the above technical solution, the containing barrel 201 is set as an upper barrel and a lower barrel, so that the containing barrel 201 can support the supporting boss 104, and the bottom of the containing barrel 201 is suspended, so that the molten metal can flow better to the bottom of the heat preservation barrel 101.

[0049] The inner wall of the lower barrel is closely attached to the inner wall of the supporting boss 104, so that the temperature generated by the heating device 106 can be effectively conducted to the molten metal in the containing barrel 201 to prevent the molten metal from solidifying too quickly.

[0050] In use, a solid metal or a metal liquid is placed inside the containing barrel 201, and a sealed space is formed by the cooperation of the sealing cover 301 and the heat preservation barrel 101. Then, a high pressure is applied to the inside of the heat preservation barrel 101 from the injection port 302 through a pressure pump. The high pressure is used to push the metal liquid to quickly pass through the filter holes 202 to achieve filtration, thus achieving the effect of improving the filtration efficiency;

[0051] The containing barrel 201 is supported by arranging a supporting boss 104 inside the heat preservation barrel 101, a cavity 105 is arranged inside the supporting boss 104, and the containing barrel 201 is further heated by a heating device 106 inside the cavity 105. While preventing the metal liquid from solidifying, the fluidity of the metal liquid can be improved and the smeltable waste residue can be reheated and smelted again, thus achieving the effects of preventing the metal liquid from solidifying and reheating and smelting the residue again.
