Feeding device for solid foam discharging rod

The invention discloses a feeding device for a solid foam discharging rod, and belongs to the technical field of natural gas collection. The feeding device comprises an upper pressure measuring valve mounted at the top of a natural gas collecting tree, and the top of the upper pressure measuring valve is connected with a storage container through an upper connecting pipeline; the storage container comprises a foam discharging rod feeding pipe which is used for feeding solid foam discharging rods. By adopting the releasing device, when the air pressure in the storage container and the air pressure in the natural gas collecting tree are balanced, the solid foam discharging rod falls into the gas recovery well along the natural gas collecting tree under the action of gravity, and thus reaction is carried out. According to the solid foam drainage rod feeding device, the solid foam drainage rod can be fed more conveniently and quickly, the problem that the traditional foam drainage rod feeding process is too compl
