In portion, material inlet end is communicated with the rectangle mixing unit.
The improvement of such scheme is the cylindrical feeding-passage and mixing chamber respectively by the first pillar and the second pillar
It is connected with horizontal shelf.
The further improvement of such scheme is that first pillar and/or the second pillar pass through adjustable mechanism and horizontal shelf
Connection so that the first pillar and/or the second pillar can move up and down on the vertical plane.
Adjustable mechanism described in such scheme is hollow sleeve, first pillar and/or the second pillar with it is described hollow
Casing threads coordinates.
The beneficial effects of the utility model are to cancel shrinking segment structure, substitute and realize gas with the conical pipeline of peripheral hardware
Compression acceleration, the length of venturi is shortened, saves space.
