Side discharge spiral classifier for mineral dressing

Abstract

The invention discloses a side discharge spiral classifier for mineral dressing, and relates to the technical field of spiral classifiers. The side discharge spiral classifier comprises a bottom plate, wherein the bottom plate is provided with a concentric-square-shaped frame and a fixed U-shaped block; the concentric-square-shaped frame is provided with a threaded rod; the outer end of the threaded rod is provided with a rotating structure; the threaded rod is provided with a movable U-shaped block; a limiting structure is arranged between the movable U-shaped block and the concentric-square-shaped frame; the movable U-shaped block is provided with a rotary supporting leg; the rotary supporting leg is connected with a frame; the fixed U-shaped block is provided with a fixed supporting leg; the fixed supporting leg is connected with the frame; the frame is provided with a feed hopper; the frame is provided with a mounting plate; the mounting plate is provided with a motor; the motor isprovided with a spiral body; the frame is provided with small-sized discharge holes, medium-sized discharge holes and large-sized discharge holes; the frame is provided with an arc-shaped groove; thearc-shaped groove is provided with an arc-shaped plate; the arc-shaped plate is provided with small-sized through holes, medium-sized through holes and large-sized through holes; the arc-shaped plateis provided with an L-shaped plate; and the frame is provided with a large material outlet pipe and the fixed U-shaped block. By using the side discharge spiral classifier, the thrust force of the movable U-shaped block to the threaded rod is reduced; the thread damage of the threaded rod is alleviated; the replacement and maintenance frequency is decreased; the classification cost is decreased;and the side discharge spiral classifier is convenient for actual use.

Description

technical field [0001] The invention relates to the technical field of spiral classifiers, in particular to a side discharge spiral classifier for mineral processing. Background technique [0002] Spiral classifier is one of the equipment for beneficiation. The spiral classifier is a kind of equipment for mechanical classification based on the principle that the specific gravity of solid particles is different, so the speed of sedimentation in the liquid is different. Then the coarse material is screwed into the feed port of the mill by the spiral blade, and the filtered fine material is discharged from the overflow pipe. The spiral classifier is referred to as the classifier. Spiral, submerged single-screw and double-screw classifiers. The classifier is mainly composed of a transmission device, a spiral body, a tank body, a lifting mechanism, a lower support (bearing bush) and an ore discharge valve. The spiral classifier is widely used in mineral processing plants. It c...

Problems solved by technology

[0005] Aiming at the above-mentioned shortcomings existing in the prior art, the present invention provides a side-discharge spiral classifier for mineral processing, which can effectively overcome the problem in the prior art that the adjusting screw is not designed after the angle adjustment of the spiral classifier. Protective structure, the thread of the adjusting screw is easy to be damaged during mineral processing and grading, and needs to be replaced and repaired after a period of use, resulting in high grading costs and inconvenient practical use. At the same time, the grading gears of the spiral classifier are fixed and cannot be adjusted. The problem
