Vibrating screen device for wet screening concrete mortar

Abstract

The invention discloses a vibrating screen device for wet screening concrete mortar. The vibrating screen device comprises a device body, wherein a movable rack capable of freely sliding in the horizontal direction is arranged in the device body, a screen is arranged in the movable rack, reset mechanisms used for resetting the movable rack are arranged on two sides of the device body, a driving mechanism used for driving the movable rack to perform reciprocating motion is mounted at the bottom in the device body, a scraping mechanism used for scraping dirt at the lower end of the screen is further arranged in the device body, and a feeding hopper is arranged at the upper end of the device body in a penetrating manner. According to the vibrating screen device, concrete is screened through fluctuating shake, the efficiency is higher as compared with that of existing horizontal vibrationscreening, besides, the concrete is effectively prevented from adhering to the bottom of the screen, the cost of manual cleaning is reduced, and meshes of the screen are blown by airflow and are effectively prevented from being blocked.

Description

technical field [0001] The invention relates to the technical field of concrete production, in particular to a concrete wet screening mortar vibrating screen device. Background technique [0002] Concrete mortar usually needs to be sieved during the manufacturing process to screen out the unqualified material particles. At present, there are many types of vibrating screens for concrete wet screening mortar on the market, with different sizes. [0003] The existing concrete wet screening mortar screening device uses a horizontal shaking method to screen the concrete. This screening method has the following defects: [0004] 1. When shaking horizontally, the stones in the concrete are easy to block the mesh holes of the screen, resulting in unsmooth screening; [0005] 2. The existing concrete screening device does not have a mechanism for cleaning the screen, which leads to the need to manually clean the screen after each use of the equipment, resulting in high labor costs. ...
