Embodiment Construction
[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0014] Referring to the accompanying drawings, a new structure with adjustable height of both light and heavy liquid phase weirs, including a base 3, the base 3 is in the shape of a ring, a handle 5 passes through the ring surface of the base 3, and the handle 5 and the sliding sleeve 6 are threaded connection, the pressure ring 4 is fixed on the base 3, and radially constrains the sliding sleeve 6; the upper end of the base 3 is equipped with a gland 1, and the gland 1 is fixed with a skimming pipe 2 through a flange. The other end of the base 3 is fixedly provided with an overflow plate 8, and the drum 7 is welded on the overflow plate 8; the handle 5 and the adjusting plate 10 are connected as one by threads, and the adjusting plate 10 is respectively fixed with a light liquid phase tube 11 and the heavy liquid phase pipe 9; the top of the light liquid pha...

The invention discloses a novel structure with functions of adjusting the heights of light and heavy liquid-phase weir crests. Handles penetrate an annular surface of a base of the novel structure and are connected with slide bushings in a threaded manner, a compressing ring is fixed onto the base by the aid of the slide bushings, the handles are integrally connected with adjusting plates in a threaded manner, light liquid-phase pipes and heavy liquid-phase pipes are respectively fixed onto the adjusting plates, a gland is mounted at one end of the base, a liquid skimming pipe is arranged on the gland, an overflow plate is fixed to the other end of the base, a rotor drum is welded on the overflow plate, light liquid-phase pipe orifices are arranged on the tops of the light liquid-phase pipes and penetrate the base, and heavy liquid-phase pipe orifices are arranged on the heavy liquid-phase pipes, penetrate the base and are close to the liquid skimming pipe; kidney-shaped holes are formed in the overflow plate, and overflow holes are formed in the adjusting plates; the handles can rotate to drive the adjusting plates, so that various difference values can be generated by change of the heights of the heavy liquid-phase weir crests and change of the heights of the light liquid-phase weir crests, heavy liquid-phase can flow over along the heavy liquid-phase pipes, and light liquid-phase can flow over along the light liquid-phase pipes. The novel structure has the advantages that the handles can rotates, so that the heights of the light and heavy liquid-phase weir crests can be steplessly adjusted in appropriate ranges, and the novel structure is applicable to places where verification of model machines needs to be repeatedly adjusted.
Description
technical field [0001] The invention relates to the technical field of adjusting the weir height of a horizontal spiral sedimentation centrifuge, in particular to a novel structure with adjustable weir heights for light and heavy liquid phases. Background technique [0002] Due to the different specific gravity of the material, the horizontal spiral decanter centrifuge is subjected to different centrifugal forces, so it will form heavy and light liquid phases and solid annular layers. Adjusting the height of the weir is an important part of the separation effect of the horizontal spiral decanter centrifuge. The existing structure is to change the height of the weir by adjusting the heavy liquid phase overflow plate and the light liquid phase overflow plate to move radially along the overflow cavity. The light and heavy liquid phases enter the corresponding effusion chambers through their respective channels. This method has poor adjustability and is more complicated to adju...
