Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and grasped.

Example 1

Referring to fig. 1, the conventional screw extrusion dehydrator has no casing, and only uses a base to support a main body 6, so that noise is diffused all around during operation, resulting in poor workshop operating environment.

To this end, referring to fig. 2, 3 and 4, the screw extrusion dehydrator is improved in structure, a silencing cover is arranged outside a main body of the screw extrusion dehydrator, specifically, the silencing cover is arranged on a base of the main body of the screw extrusion dehydrator, meanwhile, in order to maintain each part device in the cover body, the silencing cover adopts a split structure and comprises a left cover body 2, a middle cover body 1 and a right cover body 3, the cover bodies of the left part, the middle part and the right part are all prepared by a silencing plate 9, a caulking groove 51 is arranged on the base 5, two ends of the caulking groove are opened, L-shaped mounting plates 10 extend out from the bottom ends of the two sides of the left cover body, the right cover body and the middle cover body, the longitudinal ends of the L-shaped mounting plates are embedded into the caulking groove, mounting holes are arranged on the transverse ends, the mounting plates are matched with the caulking groove to facilitate the butt joint of the left cover body, the right cover body and the middle, the rubber layer is laid on the inner peripheral wall, during installation, the longitudinal ends of the left and right cover body installation plates are firstly arranged in the caulking groove, the longitudinal movement along the groove enables the ends of the left and right covers to enter the stepped ports at the two ends of the middle part, and the rubber layer is sealed.
