Vibrating screen with eccentric screen mesh

Abstract

The invention relates to a vibrating screen with an eccentric screen mesh. The vibrating screen comprises a frame, an eccentric screen plate, a cam assembly, and a limiting part, wherein an upper endof the frame is provided with a feeding port, and the other end is provided with a discharging port; the eccentric screen plate comprises a screen plate and a first rotating shaft; the sieve plate isrotatably mounted on the frame through the first rotating shaft; the first rotating shaft is disposed near one end of the screen plate; one end of the screen plate close to the first rotating shaft isa feeding end and located below the feeding port, and the other end is a discharge end facing the discharge port; the screen plate is provided with a screen mesh; the cam assembly comprises a rotation driving device, a cam and a second rotating shaft; the cam is rotatably mounted under the screen plate through the second rotating shaft; the rotation driving device is drivingly connected to the second rotating shaft to drive the cam to rotate; an outer peripheral surface of the cam abuts against the lower end surface of the screen plate; and the limiting member is disposed on the vibrating screen for limiting the turning of the screen plate. According to the vibrating screen with the eccentric screen mesh, the screen plate alternately screens upper and lower layers of fertilizer to ensurescreening quality and improves the screening efficiency.

Description

technical field [0001] The invention relates to the field of compound fertilizer production, in particular to a vibrating screen with an eccentric screen. Background technique [0002] In the process of compound fertilizer production, compound fertilizer forms particles through processes such as melting, emulsification, and granulation, but the shape and size of the produced particles often do not meet the requirements, and screening is required to select particles that do not meet the requirements. The traditional way is to screen through a sieve, but manual screening is time-consuming and laborious; the vibrating screen in the prior art generally uses a horizontal rotation for screening, and does not fully shake the upper and lower particles, so multiple screenings are generally used The method makes the screening more thorough, but in practical applications, each additional screening requires an additional sieve plate and driving device, and takes up a larger floor area. ...
