Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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 some, but not all, embodiments of the present invention. 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", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

As shown in fig. 1 to 2, the rotary drum for the glufosinate-ammonium slurry dewatering centrifuge comprises a separation section 701 and a filter section 702, wherein a threaded hole 703 connected with a front journal 10 is formed in an end face of the separation section 701, a threaded hole 703 connected with a rear journal 11 is formed in an end face of the filter section 702, a filter medium is arranged on an inner surface of the filter section 702, the filter medium is a filter screen, and a liquid outlet hole 704 is formed in a side face of the filter section 702. The suspension enters the separation section through the feeding pipe and is uniformly fed into the rotary drum from the material distribution holes under the action of centrifugal force. The solid particles with larger specific gravity are deposited on the inner wall of the rotary drum to form a slag settling layer; the liquid with smaller specific gravity forms an annular clarified liquid layer on the upper surface of the sediment layer. The sediment layer is continuously thickened along with the increase of the feeding material, the inner diameter of the clarified liquid layer is gradually reduced, when the sediment layer is reduced to the position of the liquid outlet, the sediment layer flows out of the liquid outlet, and the sediment layer is conveyed to the tail end through the screw conveyor. The sediment layer is at the in-process of backward transport, when through the filter segment, because be equipped with the filter screen on the inner wall of filter segment, can block that solid particle gets into out in the liquid hole.
