Instant steam-exploded straw treatment device

The invention discloses an instant steam-exploded straw treatment device. The instant steam-exploded straw treatment device comprises a steam explosion tank which is vertically arranged; the steam explosion tank is fixed by utilizing a bracket arranged on the side face of the steam explosion tank; a feeding hole is formed in the top of the steam explosion tank; a cabin door which is hydraulically controlled is arranged at the feeding hole; a T-shaped connecting piece is arranged at one end of the cabin door; the lower end of the T-shaped connecting piece is hinged to a side wall of the feeding hole; the right end of the T-shaped connecting piece is hinged to a hydraulic rod; the other end of the hydraulic rod is hinged to an outer wall of the steam explosion tank and a buckle is arranged at the other end of the cabin door; the side wall of the steam explosion tank is provided with an arc-shaped door which is coaxial with a tank body of the steam explosion tank; a pressure gauge and a gas inlet are arranged on the side wall of the steam explosion tank; the gas inlet is connected with a steam channel; and a first check valve is arranged at the gas inlet. By adopting the arc-shaped door, the pressure relief area is enlarged and steam explosion is realized.
