The invention provides a pressurized melt filter. The pressurized melt filter comprises a heating box body and a plurality of filtration chambers, wherein the lower portions of the filtration chambersare provided with a first melt input port, the lower portions of filter bodies are provided with a second melt input port, the first melt input port is in butt joint with the second melt input port,the upper portions of the filtration chambers are provided with a first melt output port, the upper portions of the filter bodies are provided with a second melt output port, the first melt output port is in butt joint with the second melt output port, a first tee valve is arranged between the first melt input port and a melt inlet, a second tee valve is arranged between the first melt output portand a melt outlet, the heating box body is also internally provided with a booster pump, the booster pump is arranged in the melt inlet, and the booster pump is communicated with the first tee valve.The pressurized melt filter has the advantages that through pressurization of the booster pump, the process pressure requirements are met, and the unlimited pressurization of a threaded rod is avoided, thereby prolonging the service life of the threaded rod.
