干粉搅拌站及其振动筛

Dry powder mixing plant and vibrating screen thereof

Abstract

本实用新型公开了一种振动筛,该振动筛包括:底座、振动筛筛体、弹性部件以及减震器。具体地,所述弹性部件安装在所述底座上以支撑所述振动筛筛体;所述减震器设在所述底座与所述振动筛筛体之间且与所述底座和所述振动筛筛体相连。根据本实用新型实施例的振动筛,筛分结束时,减震器可以快速的使振动筛筛体停止震动,避免振动筛筛体长时间低频震动,降低对干粉搅拌站机械机构的损害。此外,相对传统技术中的采用偏心电机反接制动,不仅保护了偏心电机,同时也避免产生瞬时高电流而造成对控制系统元件的损坏。结构简单,使用方便,且提高了干粉搅拌站的使用寿命。此外,本实用新型还公开了一种具有该振动筛的干粉搅拌站。
The utility model discloses a vibrating screen. The vibrating screen comprises a base, a vibrating screen body, an elastic component and a vibration damper. Specifically, the elastic component is arranged on the base so as to support the vibrating screen body; the vibration damper is arranged between the base and the vibrating screen body and is connected with the base and the vibrating screen body. According to the vibrating screen disclosed by the embodiment of the utility model, when screening is completed, the vibration damper enables the vibrating screen body to stop vibrating quickly, so that the long-time low-frequency vibration of the vibrating screen body is prevented, and the damages of mechanical mechanisms of a dry powder mixing plant are reduced. Moreover, compared with the traditional technology that an eccentric motor is adopted for plug braking, the eccentric motor is protected, and simultaneously the damages of control system elements caused by instantaneous high current are also prevented. The vibrating screen is simple in structure and convenient to use, and the service life of the dry powder mixing plant is prolonged. Moreover, the utility model further discloses a dry powder mixing plant with the vibrating screen.
