Detailed Description

The present invention will be described in further detail with reference to specific examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the present disclosure, as defined by the following claims.

Example 1

As shown in the figure, the utility model discloses a horizontal scraper coal slime centrifuge observation door of unloading with function of ventilating, include: the observation door body of setting in centrifuge door 3 below, the observation door body is including observing door frame 6, observation window, connecting pipe 7, orifice plate and handle 8, it installs to observe door frame 6 on centrifuge door 3, and should observe door frame 6's top and bottom and cooperate with centrifuge door 3 respectively, the observation window inlays the dress and is in observe the centre of door frame 6, the one side of observing door frame 6 is equipped with the pivot and is connected with centrifuge door 3, the both ends of connecting pipe 7 are all installed on observation door, be equipped with a breather plate 9 between the bottom of connecting pipe 7 and the observation window in order to be used for communicating with outside atmosphere, handle 8 is installed on the right side of observing door and window, and this handle 8 installation is connected with connecting pipe 7.
