Exhaust connection structure of supercharger of diesel

Provided is an exhaust connection structure of a supercharger of a diesel. The exhaust connection structure comprises an exhaust pipe, the supercharger, an exhaust flange, sealing rings, a silencer and a silencer support, wherein the supercharger is fixedly connected to the exhaust pipe of an engine and connected with the large end of the exhaust flange through bolts, the exhaust flange is connected with the air inlet of the silencer through the sealing rings, the silencer support is connected with the exhaust pipe, the top surface of the silencer support is connected with a base of the silencer, each sealing ring is provided with an opening, and the openings of the four sealing rings are alternately formed in a 90-degree mode. By means of the exhaust connection structure, connection between the supercharger and the silencer is flexible connection, the disassembly and assembly difficulty is effectively lowered, cold looseness and air leakage do not happen easily on the connection portion of the supercharger and the silencer, the connection reliability is greatly improved, mating main machine products can be safely used under the condition of long-term vibration, and the overall reliability of the diesel is improved.
