Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

Example (b):

referring to fig. 1, the present invention provides a technical solution: double butterfly valve airlock of unloading, including inlet pipe 1, the fixed connecting pipe 2 that is provided with in right side of inlet pipe 1, the fixed material pipe 3 that waits that is provided with of downside of connecting pipe 2, the fixed air hammer knocker 4 that is provided with of right side wall of material pipe 3 waits can be knocked the lateral wall of material pipe 3 for the powder shattering of adhesion drops, the dismantled and assembled butterfly valve 5 that is provided with of lower extreme of material pipe 3 waits, the dismantled and assembled material pipe two 6 that is provided with of lower extreme of butterfly valve 5, the fixed air hammer knocker two 7 that is provided with of right side wall of material pipe two 6 waits, the dismantled and assembled butterfly valve two 8 that is provided with of lower extreme of material pipe two 6, the dismantled and assembled discharging pipe 9 that is provided with of butterfly valve two 8, butterfly valve two 8 close when butterfly valve 5 opens, and the in-process of unloading keeps encapsulated situation like this and goes on.
