Ultrahigh-pressure material barrel with heat preservation effect

The utility model relates to the technical field of ultrahigh-pressure equipment, in particular to an ultrahigh-pressure material barrel with a heat preservation effect, which comprises a material barrel body. The heating coil pipe is arranged on the surface of the material barrel body, when heated purified water passes through the material barrel body, the material barrel body can be heated, when a piston in the material barrel body moves to the discharging plug end, a switch valve on the adding pipe is opened, hot water enters the material barrel body synchronously to heat the inner wall of the material barrel body, and meanwhile, the heating coil pipe can heat the inner wall of the material barrel body. The pressure relief valve is opened, purified water entering the material barrel body flows back into the purified water tank from the pressure relief pipe, the outer wall and the inner wall of the material barrel body can be synchronously heated at the same time, after the set heating duration is reached,
