Powder concentrator being convenient for fine powder collection

Abstract

The invention discloses a powder concentrator being convenient for fine powder collection and relates to the technical field of mineral powder screening. The powder concentrator comprises a powder concentrator body, wherein the powder concentrator body comprises a transmission device, a feeding hopper, a shell body, a rotor and two cyclone barrels; an air inlet is arranged at the bottom end of theshell body; a fan is connected into the air inlet; the shell body communicates with the feeding hopper; ventilating pipes correspondingly communicate with two sides of the top end of the shell body;two ends of the ventilating pipes are both positioned outside the shell body; the transmission device is arranged at the inner top of the shell body; the cyclone barrels correspondingly communicate with the two ends of the ventilating pipes; openings are formed in the side walls of the cyclone barrels; collecting tanks are connected onto the openings; inclined filtering plates are rotationally connected into the cyclone barrels; the ends, far away from the rotational connecting positions, of the filtering parts are positioned in the openings, and springs are connected between the ends and thebottom ends of the openings; vibrating motors are arranged on the outer walls of the cyclone barrels; and output shafts of the vibrating motors penetrate through the side walls of the cyclone barrelsand are connected with the filtering plates. By adoption of the powder concentrator, the problem that when being collected, fine powder is blown by airflow to form flying dust, and then part of the fine powder is wasted can be solved.

Description

Technical field [0001] The invention relates to the technical field of mineral powder screening, in particular to a powder concentrator that is convenient for fine powder collection. Background technique [0002] The classifier is generally used for the screening of ore and stone. The classifier separates the fine and coarse ore powder. The classifier includes a transmission device, a feeding hopper, a shell, a rotor and a cyclone, the shell and the feed The bucket is connected, the top of the shell is connected with a vent pipe, the vent pipe is provided with a transmission device, and the two ends of the vent pipe are respectively connected with the cyclone. When the powder concentrator is running, the transmission device drives the rotor to rotate. When the rotor rotates, the bulky raw materials are thrown onto the inner wall of the shell due to centrifugal force, and fall from the inner wall of the shell to the bottom of the shell, while the fine powder enters the cyclone wit...
