Multi-screen vibrating screen with vibration damping function

Abstract

The invention relates to a multi-screen vibrating screen with a vibration damping function. The multi-screen vibrating screen comprises a support, a vibration reduction tray, a vibration box and a driving part. the support is arranged on the ground; the vibration reduction tray comprises a bottom plate and a supporting plate, the supporting plate is oppositely arranged above the bottom plate, thebottom plate is arranged with an elastic plate, a fixing screw and a first fixing seat; the middle of the elastic plate is bent and is fixedly connected with the lower end of the supporting plate, theelastic plate is fixedly connected with the bottom plate through a fixing screw, the first fixing seat is arranged at one end of the elastic plate, the upper end surface of the first fixing seat is covered with a rubber pad, the lower end face of the supporting plate is provided with a second fixing base, the second fixing base is arranged corresponding to the first fixing base; the vibration boxis detachably arranged on the upper end surface of the supporting plate, a feeding opening and discharging openings are formed in the vibration box, at least two screens are arranged between the feeding opening and the discharging openings in parallel at intervals; the driving part drives the screens to vibrate, the impact of the second fixing seat can be effectively buffered through the rubber pad, a part of vibration is counteracted by the elastic plate at the same time, so that the influence of vibration on the support is reduced.

Description

technical field [0001] The invention relates to the field of fertilizer production, in particular to a multi-mesh vibrating screen with a vibration-reducing function. 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 method is to screen through sieves, but manual screening is time-consuming and laborious; thus, different vibrating screens have been developed for fertilizer screening. In the prior art, in order to ensure screening efficiency or improve screening accuracy, people use multi-screen vibrating screens to Screening fertilizers, but due to the increase in the number of screens, the vibration amplitude of the entire vibrating screen frame becomes larger.

The traditional method is to screen through sieves, but manual screening is time-consuming and laborious; thus, different vibrating screens have been developed for fertilizer screening. In the prior art, in order to ensure screening efficiency or improve screening accuracy, people use multi-screen vibrating screens to Screening fertilizers, but due to the increase in the number of screens, the vibration amplitude of the entire vibrating screen frame becomes larger. For the parts that are fixedly connected into welding or riveting, long-term vibration will lead to deformation of the connection, and in severe cases, it will lead to structural collapse. Bad
