Fiber material dispersing and feeding device

Abstract

The invention discloses a fiber material dispersing and feeding device which comprises a screen, a first fixed frame and a second fixed frame; the first fixed frame and the second fixed frame are oppositely arranged and are provided with sliding rails respectively; each sliding rail is provided with a slider; one side of the screen is fixedly connected with the slider on the first fixed frame through a connecting shaft; the other side of the screen is fixedly connected with the slider on the second fixed frame through a connecting shaft; the first fixed frame or the second fixed frame is provided with a drive mechanism; and the drive mechanism drives the screen to freely slide along the sliding rails. By adopting the fiber material dispersing and feeding device disclosed by the invention,the fiber material unloading efficiency and quality can be effectively improved, the fiber material unloading is more rapid and labor-saving, and fiber materials are more uniform in distribution without clumping, so that a preparation speed, the strength and the quality of the concrete and the like are guaranteed.

Description

technical field [0001] The invention relates to a fiber material dispersion feeding device. Background technique [0002] Fiber materials (such as steel fibers, etc.) are added to many modern concretes to increase the compressive and tensile strength of concrete, such as ordinary steel fiber concrete, reactive powder concrete (RPC) and ultra-high performance concrete (UHPC). The feeding requirements of fiber materials are relatively strict. It is necessary to ensure that the fiber materials are dispersed and evenly attached to the concrete when they are fed, otherwise it is easy to cause the fiber materials to agglomerate, resulting in the quality of the prepared concrete not meeting the requirements or damaging the mixer. [0003] In actual engineering production, there are special fiber material feeding machines that can better complete the fiber material underground feeding process. However, these existing devices are not suitable for laboratory production or when using s...

Problems solved by technology

The efficiency of this method is very low, and it is easy to hurt hands. In the preparation process of some concrete with strict requirements on mixing time, it is difficult to complete the blanking process of fiber materials within the required time using this original method.

Today, as fiber-containing concrete is becoming more and more common, more and more laboratories are paying more attention to the research and preparation of fiber-based concrete. The original concrete addition method is difficult to adapt to the current requirements.
