Horizontal spiral discharge settling centrifuge

[0016] The present invention will now be described in further detail with reference to the drawings. These drawings are all simplified schematic diagrams, which merely illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.

[0017] Such as figure 1 with figure 2 As shown, a horizontal spiral unloading sedimentation centrifuge of the present invention includes a rotating drum 1 and a screw 2. The screw 2 has spirally arranged blades 21, and the outer cover of the rotating drum 1 is provided with a shell 3, and the shell 3 is provided with a feed port 31 communicating with the inner cavity of the screw 2, the lower end of the housing 3 is provided with a liquid discharge port 32 at one end close to the feed port 31, and a slag discharge port 33 at the other end. The inner wall of the drum 1 is provided with at least 20 grooves along the circumferential direction. By opening a plurality of grooves on the inner wall of the drum 1, it can prevent the liquid phase from forming a water film and prevent the solid phase from accumulating, thus avoiding the wear of the blade 21. The solid phase will partially accumulate in the grooves, but not Affect the normal operation of the blade.

[0018] In an embodiment of the groove, the radial cross-sectional shape of the groove is rectangular.

[0019] In an embodiment of the groove, the radial cross-sectional shape of the groove is an arc shape.

[0020] Specifically, the inner diameter of the rotating drum 1 is 530 mm, and the number of grooves on the inner wall of the rotating drum 1 is 24-36.

[0021] Preferably, the 24-36 grooves are evenly arranged on the inner wall of the drum 1 along the circumferential direction.

[0022] Taking the above-mentioned ideal embodiment according to the present invention as enlightenment, through the above-mentioned description content, relevant staff can make various changes and modifications without departing from the scope of the technical idea of ​​the present invention. The technical scope of the present invention is not limited to the content of the description, and its technical scope must be determined according to the scope of the claims.
