Double-layer spiral vibrating screen

Abstract

The invention discloses a double-layer spiral vibrating screen and relates to the technical field of vibrating screens. The double-layer spiral vibrating screen comprises a base, a vibrating cabin anda spiral vibrating device, wherein the base comprises a circular disc and a circular ring; the circular ring is fixed on one surface of the circular disc; a plurality of stepped holes are formed in one surface of the circular ring and are matched with stepped columns of the vibrating cabin; a plurality of stepped columns are arranged on one surface of the vibrating cabin; the circumferential sidefaces of the stepped columns are matched with springs; the internal surface of the vibrating cabin is matched with the spiral vibrating device; the spiral vibrating device comprises a spiral vibrating screen, a spiral vibrating plate and a central shaft; the spiral vibrating screen and the spiral vibrating plate are arranged on the circumferential side face of the central shaft; the spiral vibrating plate is positioned below the spiral vibrating screen; a vibration motor device is fixed at one end of the central shaft of the spiral vibrating device; and the other end of the central shaft is matched with a dustproof cover. According to the invention, through action of the double-layer spiral vibrating screen, the vibration motor and the vibrating cabin, the problems that material in screenmeshes of the vibrating screen is jammed and excessive materials of the vibrating screen are piled up are solved.

Description

technical field [0001] The invention belongs to the technical field of vibrating screens, in particular to a double-layer spiral vibrating screen. Background technique [0002] At present, when the existing vibrating screen uses vibration to screen the particle size of the material, some difficult-to-screen granular materials are often stuck in the screen holes of the vibrating screen. With the extension of the screening working time, the screen holes The number of jams is increasing, and the number of screen holes that can be used for effective screening is decreasing, resulting in a decrease in the screening efficiency of the vibrating screen. Especially when the vibrating screen is used to accurately screen the particle size of the material, the material jam phenomenon in the screen hole will directly affect the accuracy of the screening test result. Therefore, the material jam problem in the screen hole in the vibrating screen is one of the key technical problems in the...
