Material sieving device and operation method thereof

Abstract

The invention discloses a material sieving device and an operation method thereof. The material sieving device comprises a rack. A protecting cover is mounted on the rack, and a material sieving mechanism and a material separating mechanism are mounted in the protecting cover. The material sieving mechanism comprises a material sieving net and a material sieving steel ring, and the material sieving net is connected to the material sieving steel ring through a stretching spring. A vibration mechanism is arranged below the material sieving net and comprises a transmission rod, a cam and a disc.The material separating mechanism comprises a three-blade material separating plate, a rotating shaft, a coupling and a motor. The motor is arranged on the lower portion of a material collecting box,and the interior of the material collecting box is divided into a finished material bin and a waste material bin which correspond to the material sieving net and a material filtering trough. Accordingto the material sieving device and the operation method thereof, building materials on the material sieving net are sieved and filtered through the material sieving mechanism and the vibration mechanism, the material sieving device is good in vibration effect, and the mechanism transmission mode is simple; and secondly, the situation that the large-particle materials remain on the material sieving net, and consequently, the sieving efficiency of the subsequent process is affected can be avoided through the material separating mechanism, the whole device treats the materials in a graded mode,the collecting effect is better, reutilization in the subsequent process is facilitated, and energy conservation and environmental protection are achieved.

Description

technical field [0001] The invention relates to the technical field of material screening, in particular to a material screening device and an operating method thereof. Background technique [0002] In the field of construction processing, many construction materials need to be screened before use, and unsatisfactory parts are kicked out to ensure the construction quality. Patent No. 201320434765.7 discloses a building material processing and screening device. This technology has simple structure, convenient maintenance and high practicability. However, because the screening mechanism in this technology is a simple orifice plate, the rotation of the orifice plate depends entirely on the ring shape. Driven by the gear, that is, the orifice plate can only rotate in the horizontal direction. In the rotating state, affected by the centripetal force, the building materials inside the sieve drum will form a swirling flow, and many materials will be twisted into a whole and rarely ...

Patent No. 201320434765.7 discloses a building material processing and screening device. This technology has simple structure, convenient maintenance and high practicability. However, because the screening mechanism in this technology is a simple orifice plate, the rotation of the orifice plate depends entirely on the ring shape. Driven by the gear, that is, the orifice plate can only rotate in the horizontal direction. In the rotating state, affected by the centripetal force, the building materials inside the sieve drum will form a swirling flow, and many materials will be twisted into a whole and rarely dispersed. The screening effect is greatly reduced, and it is difficult to achieve the screening purpose at one time, and rework is often required, which is time-consuming and laborious

[0003] Secondly, in traditional construction material screening devices, there are often only corresponding equipment for screening materials that meet the requirements, but there is no device for corresponding processing of materials that do not meet the requirements, resulting in the need for subsequent processing, which takes a long time and is cumbersome. , bringing unnecessary trouble to material screening
