Four-link type bin arch breaking system and method and application of four-link type bin arch breaking method

Abstract

The invention belongs to the technical field of material conveying instruments, and discloses a four-link type bin arch breaking system and method and application of the four-link type bin arch breaking method. During the arch breaking process in the first stage, a linear driving device driving rod stretches out to drive a swinging arm and a first arc-shaped plate to swing around hinge points of the swinging arm and the first arc-shaped plate with a storage bin; meanwhile, an adjustable pull rod at the lower end of the first arc-shaped plate drives a second arc-shaped plate to swing around a hinge point of the second arc-shaped plate with the storage bin; materials start to fall down, and the arching phenomenon is eliminated; during the falling process of the materials in the second stage,existing cavities are filled with the materials, and when the materials act on overflow prevention plates on the two sides, the overflow prevention plates respectively swing around hinge points withthe first arc-shaped plate and the second arc-shaped plate, so that a partial space is reserved; and the linear driving device driving rod retracts to drive the swinging arm and the first arc-shaped plate to swing around the hinge points of the swinging arm and the first arc-shaped plate with the storage bin to start resetting. According to the four-link type bin arch breaking system and method and the application of the four-link type bin arch breaking method, the arch breaking of granular materials, powdery materials and wet-bonded materials with high water content can be rapidly completed.

Description

technical field [0001] The invention belongs to the technical field of material conveying equipment, and in particular relates to a four-link type silo arch breaking system, an arch breaking method and an application thereof. Background technique [0002] At present, the closest existing technology: in the process of modern industrial production, with the development of mining, mineral processing, metallurgy, chemical industry, fertilizer, grain and building materials, the role of silos is becoming more and more important. During the use of the silo, because the internal force of the material is greater than the gravity, it often leads to the occurrence of arching. This problem is often solved by changing the structure of the silo or adding a corresponding arch breaking device. At present, the most commonly used arch breaking methods include: vibration arch breaking, high-pressure fluidized arch breaking, and mechanical forced arch breaking, or a combination of the above met...
