Settling double-cone section spiral discharging filter centrifuge

Abstract

The invention relates to a settling double-cone section spiral discharging filter centrifuge. The settling double-cone section spiral discharging filter centrifuge comprises a machine seat, a drivingmotor fixed to the machine seat, a differential mechanism and a cylindrical shell. A double-cone screen rotary drum spiral assembling unit is arranged in the cylinder shell, and the driving motor is connected with the double-cone screen rotary drum spiral assembling unit through the differential mechanism. The double-cone screen rotary drum spiral assembling unit comprises a rotary drum assembly and a spiral feed pusher assembly located in the rotary drum assembly, a straight cylinder section, a first cone cylinder section and a second cone cylinder section are sequentially included from frontto back, and the thin ends of the first cone cylinder section and the second cone cylinder section are coaxially and fixedly connected. Screen holes are densely formed in the rotary drum wall of thestraight cylinder section, the first cone cylinder section and the second cone cylinder section of the rotary drum assembly. The settling double-cone section spiral discharging filter centrifuge has the advantages that a solid phase material is subjected to extrusion crushing and dehydration drying in sequence in the first cone cylinder section and the second cone cylinder section of the rotary drum assembly driven by the spiral feed pusher assembly, the action distance of extrusion crushing is effectively extended and time of extrusion crushing is effectively prolonged and extruded water is thrown out through the screen holes in time, and the crushing and dehydration effects are better.

Description

technical field [0001] The invention belongs to the field of mechanical equipment for solid-liquid separation, and in particular relates to a sedimentation double-cone segment spiral discharge filter centrifuge. Background technique [0002] The screw settling discharge centrifuge has a drum and a screw pusher located in the drum. The drum and the screw feeder rotate at a high speed under the drive of the motor (due to the difference in the speed of the two due to the differential). The feed pipe extends into the screw feeder and the wall of the screw feeder is provided with a distribution hole, the material enters the screw feeder from the feed pipe and finally enters between the screw feeder and the drum through the distribution hole . The material is placed with the drum at high speed. Under the action of centrifugal force, the material is subjected to a centrifugal acceleration several thousand times greater than the specific gravity. The solid particles in the material...

AI Technical Summary

Problems solved by technology

[0003] The drum and the screw pusher of the spiral sedimentation discharge centrifuge in the prior art are composed of a straight cylinder and a single cone cylinder located at one end of the straight cylinder. The screw pusher is located in the drum and coiled on the side wall of the screw pusher The helical blades are matched with the drum wall of the drum, and its disadvantages are: the dehydration effect is not good, and there is no screen hole for the extruded water to be thrown out on the drum wall, so it settles in the drum. The water extruded by the solid phase on the inner wall cannot be discharged in time during the process of advancing to the slag outlet, which affects the dehydration effect; The effect is not good and the water contained in the solid phase substance cannot be further removed after reaching the single cone, and there is no drying effect
