Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1, 2 and 3, the sectional type high-efficiency static pressure box comprises a static pressure box body 1, wherein the static pressure box body 1 is divided into an upper box body 101 and a lower box body 102; the top of the upper box body 101 is provided with an air inlet 7, the interior of the upper box body 101 is connected with a liquid tank filter 3, and the outer wall of the upper box body 101 is connected with an L-shaped connecting piece 8; the outer wall of the lower box body 102 is connected with a U-shaped connecting piece 9, and the bottom of the lower box body 102 is connected with a flow dispersing plate 10; the L-shaped connecting piece 8 is connected with the U-shaped connecting piece 9 through an M4 pull nut 6; the lower box 102 is fixedly attached to the ceiling plate 11.
