Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] as attached figure 1 As shown, the thickener is composed of a motor 1, a reduction box 2, a worm 3, a worm wheel 4, and a rake frame 5. The motor 1 drives a worm gear mechanism composed of a worm 3 and a worm wheel 4 through a reduction box 2. The main shaft 12 is installed in the inner hole of the worm wheel. , Cooperate with the gap of the worm gear, the main shaft can move up and down in the hole of the worm gear to lift and lower the rake frame. The rake frame 5 is made up of four rakes, which are evenly distributed in the concentration pool, and the long rakes are spaced apart from the short rakes. One end of each rake is fixed on the wheel disc at the lower end of the main shaft, and can move up and down with the main shaft 12.

Abstract

The present invention discloses a novel overflow apparatus thickener, which comprises a motor, a reduction gearbox, a material discharge device, a heightened overflow weir, T-shaped three-way pipes and other structures, wherein the overflow weir is made from concrete, the width is the same as the wall thickness of the rack on the outer side of an annular chute, the height is the same as the wall height of the rack on the outer side of the annular chute, a plurality of water outlets are uniformly arranged on the overflow weir position according to the flow rate, and the T-shaped three-way pipes are arranged on the water outlet positions. According to the present invention, the technical problems that the water outlet gap between the overflow device and the annular baffle requires frequent cleaning of the produced calcium, the annular baffle easily rot, the replace time of the annular baffle is long, the work difficulty is high and the like are solved, the maintenance cost is reduced, and the equipment service life is prolonged.

Description

technical field [0001] The invention relates to a mine thickener, especially a thickener used for thickening lead concentrate. Background technique [0002] Thickener is a machine that concentrates ore pulp from low concentration to high concentration. It is mainly used for concentration and purification of all mixed liquids containing solid materials in industries such as mineral processing, chemical industry, infrastructure and sewage treatment. [0003] Commonly used center-driven thickeners are mainly composed of circular thickeners, rake racks, transmission devices, rake rack lifting devices, feeding devices, unloading devices, and overflow devices. The overflow device is composed of an annular chute, an overflow weir, an annular baffle mechanism and a screw connection mechanism. Its working process is as follows: the ore slurry is fed into the center of the thickening pool through the feeding device, the minerals settle under the action of gravity, and finally sink to...
