Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so as to make the technical solutions of the present invention easier to understand and grasp.

In the present embodiment, it should be understood that the terms "middle", "upper", "lower", "top", "right", "left", "above", "back", "middle", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description of the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

In the present embodiment, if the connection or fixing manner between the components is not specifically described, the connection or fixing manner may be a bolt fixing manner, a pin connecting manner, or the like, which is commonly used in the prior art, and therefore, details thereof are not described in the present embodiment.

A steam impact device for preventing wood chip buffer bin bridging, as shown in figure 1-2, comprises a waste heat steam pipe 1 for conveying waste heat steam, a three-way joint 2 arranged at the tail end of the waste heat steam pipe 1, a plurality of steam distribution pipes 3 arranged at the side of the buffer bin in an annular array and communicated through the three-way joint 2 and used for distributing the steam into a bottom air injection pipe 4 and an upper end air injection pipe 5, the bottom air injection pipes 4 are arranged at the lower end of the steam distribution pipes 3 at equal intervals and the tail ends of the steam distribution pipes extend into the buffer bin, the wood at the bottom of the buffer bin is impacted by utilizing the sprayed steam to avoid the wood bridging, the upper end air injection pipes 5 are arranged at the upper end of the steam distribution pipes 3 at equal intervals and the tail ends of the steam distribution pipes extend into the buffer bin to spray the steam to push the wood at the upper end of the buffer bin to move so as to avoid the wood bridging at the upper end of the bin, the device comprises a bottom gas injection pipe 4, an upper gas injection pipe 5, a first electromagnetic valve 6, a steam jacking mechanism 7, a steam inlet combination 8 and a pressure sensor 9, wherein the first electromagnetic valve 6 is arranged on the bottom gas injection pipe 4 and the upper gas injection pipe 5 and used for controlling the bottom gas injection pipe 4 and the upper gas injection pipe 5 to spray steam, the steam jacking mechanism 7 is arranged inside a storage bin and used for jacking wood by utilizing the steam so as to push the wood to move, and thus the problem of wood bridging is solved; and a first pressure relief valve 11 is arranged on the waste heat steam pipe 1.

The steam jacking mechanism 7 comprises a support frame 71, a steam steaming body 72 arranged on the center of the support frame 71, a moving rod 73 arranged inside the steam steaming body 72, a jacking cap 74 arranged at the top of the moving rod 73 and used for abutting and jacking wood and an umbrella cap 75 arranged on the support frame 71 and positioned below the support frame 71, wherein after high-pressure steam is flushed into the steam steaming body, the moving rod 73 is pushed by air pressure to move upwards; the bottom of the moving rod 73 is also provided with a frustum 76 for pushing the wood at the bottom of the storage bin, and the moving rod 73 can also descend to extrude the wood to move downwards; the bottom of support frame 71 is provided with range finding sensor 77 for detect the inside timber height in feed bin bottom, admission combination 8 includes steam inlet pipe 81, sets up second solenoid valve 82 on the steam inlet pipe 81 sets up check valve 83 on the steam inlet pipe 81, and sets up the second relief valve 84 of steam inlet pipe 81 side.
