Novel filtration formula spherical pig receiver

The utility model discloses a novel filtration formula spherical pig receiver locates to carry on the reaming processing and welds the filter -tank with closing heat -extraction system pipeline connection at the closely fast open -blind board end of spherical pig receiver, and insert through the reducing and close the calandria line, be provided with the filter in the filter -tank, the filter -tank is provided with and filters the groove support rank, the filter is provided with the filter step, the filter passes through the filter step is sat and is sealed filter on the groove support rank. The utility model discloses simple structure, maneuverability is strong, can effectively solve among the spherical pig recovery process to spherical pig receiver pressure release, flowing back the time, and impurity such as mud, sand, dirt lack effective filtration and block up the problem of closing the heat -extraction system pipeline in the fluid, can solve effectively also that impurity such asmud in the fluid, sand,
