The invention discloses a melt filtering metering device. The melt filtering metering device comprises a shell, a discharging switching valve, a feeding switching valve, a discharging valve, an exhaust pipe, a melt inlet pipe, a heat medium outlet pipe, a discharging pipe, a melt outlet pipe, a heat medium inlet pipe, a liquid discharging opening, a sewage draining opening and a metering pump; a heat medium heating cavity is formed in the shell; the metering pump is fixed to a metering pump bracket; the heat medium outlet pipe is arranged on the melt inlet pipe in a sleeving manner; the heat medium inlet pipe is arranged on the melt outlet pipe in a sleeving manner. According to the melt filtering metering device disclosed by the invention, a melt filter and the metering pump are arranged in the same device; the flow of a melt before spinning is shortened; the degradation of the melt is avoided; the product quality is improved; the heat medium in the heat heating cavity ensures the consistency of the temperature of the melt which is discharged from the filter and the temperature of the melt in the metering pump, and the influence on the control and the product quality of the flow rate of the melt caused by the change of the melt temperature is avoided.
